Description

Car seat headrest with light

Technical field

The invention belongs to the technical field of automobile seats, and specifically relates to a car seat headrest with a lighting lamp.

Background technique

With the development of the automobile industry, people's requirements for automobile functionality are increasing day by day, especially for rear passengers, who need more adequate lighting. Traditional lighting for rear passengers is usually set on the top of the car, but when the passengers are reading a book or similar situations, the light source is far away and cannot provide sufficient brightness for the rear passengers. If in order to meet the demand, the brightness of the lights on the top of the car is blindly increased, especially at night, it will seriously affect the driver's driving safety and cause the driver to be unable to see the rearview mirror clearly. Solving the above problems has become a top priority.

Contents of the invention

In order to solve the above technical problems, the present invention provides a car seat headrest with a lighting lamp, which can provide lighting for rear passengers without affecting the driver's driving safety.

In order to achieve the above objects, the technical solutions of the present invention are as follows:

Using the above structure, the lamp holder is fixed on the headrest frame, ensuring the reliability of the installation and long service life.

Preferably: the mounting part has a hollow structure. The above structure is adopted to ensure installation reliability while reducing weight and meeting vehicle lightweight requirements.

Preferably, the headrest rod includes two oppositely arranged tubular support rods, and each of the support rods includes a support section, a bending section and a mounting section from top to bottom. Using the above structure, the impact resistance strength of the headrest rod can be effectively improved by increasing the design of the bending section, and the safety of the seat headrest can be improved.

Preferably: the support section has two first flat notches and a second flat notch distributed up and down, and there is an included angle between the extending surfaces of the first flat notch and the second flat notch; the head The pillow frame has two assembly grooves for respectively fixing the corresponding support sections. Each assembly groove has a first engaging protrusion adapted to the first flat notch and a second engaging protrusion adapted to the second flat notch. Snap-on bump. The above structure can reliably fix the relative position of the headrest frame and the headrest rod, prevent the headrest frame from rotating relative to the support rod, and also prevent the headrest frame from sliding out of the support rod and being separated from it.

Preferably: the lower part of the lamp holder has a support part, and the lower end of the support part has two positioning grooves that are adapted to the corresponding bending sections. With the above structure, the bent section of the support pole can provide support for the lamp holder through the support portion, thereby improving the reliability of the installation of the lamp holder. Moreover, the positioning groove can further limit the lamp holder to prevent it from shaking.

Preferably: the outer edge of the rear end of the lamp holder has an annular slot, the groove wall of the annular slot has a ring of snap-in structures distributed in an array, and the inner surface of the lampshade has a ring that can be inserted into the annular slot and connected with The snap-in structure is suitable for the columnar snap-in structure. The above structure enables the lampshade to be reliably installed on the lamp holder.

Preferably, the clamping structure includes a clamping interface and a clamping protrusion, and the columnar clamping structure includes a claw that is adapted to the card interface and a snap ring that is adapted to the clamping protrusion. With the above structure, the lampshade can be mounted on the lamp holder more reliably through the mixed arrangement of the snap interface and the snap protrusion as well as the mixed arrangement of the claws and the snap ring.

Preferably: the inner surface of the lampshade has reinforcing ribs. Adopting the above structure can effectively improve the strength of the lampshade and extend its service life.

Preferably, the lamp holder is provided with three weight-reducing grooves, and reinforcing blocks are provided in each of the three weight-reducing grooves. The above structure not only reduces weight, meets the vehicle's lightweight requirements, but also ensures the strength of the lamp holder itself.

Compared with the prior art, the beneficial effects of the present invention are:

The car seat headrest with lighting provided by the present invention has a novel structure and good reliability. It can provide close-range lighting for rear passengers, meet the needs of rear passengers for lighting brightness, and enrich the seat headrest. At the same time, due to the low position of the light source, it will not affect the driver's observation of the rearview mirror, ensuring driving safety.
