Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seat backboards, and particularly relates to a lightweight seat backboard. Background Art

[0002] Automobiles have become a common means of transportation. The automobile seat backboard is an important part of an automobile, which is used to enable drivers or passengers to sit in the automobile safely and stably. During the use of automobile seats, in order to improve comfort, it is desired that the seat backboard assembly be more lightweight. However, the existing seat backboards are assembled from multiple parts, resulting in a complex overall structure and assembly process, and also causing problems such as a large volume and high weight of the seat backboard. Such automobile seat skeletons can no longer meet the requirements of vehicle lightweighting. In addition, the existing seat backboards are mostly solid, and the breathability is insufficient when users lean on the backboard, making the comfort of use not ideal. Therefore, there is an urgent need for a lightweight seat backboard to solve the above problems. Summary of the Utility Model

[0003] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a lightweight seat backboard.

[0004] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0005] A lightweight seat backboard includes a seat plate. Support side plates are installed on both sides of the top of the seat plate. The two support side plates are arranged opposite to each other. Assembly grooves are provided on the inner sides of the two support side plates. Assembly blocks are installed in the assembly grooves. A lightweight skeleton is installed between the two assembly blocks. An air-permeable support plate is installed on the front of the lightweight skeleton. A limiting frame is installed on the outside of the air-permeable support plate. An air-permeable foam layer is provided in the limiting frame. A backrest mesh surface is installed on the outside of the limiting frame. A number of air holes are provided on the backrest mesh surface. A backboard is installed on the back of the lightweight skeleton. A number of air slots are provided on the backboard, which are inclined from the inside to the outside and from top to bottom. A screen is installed on the outside of the air slots. A top seat is also installed between the two support side plates. The top seat is installed on the top of the lightweight skeleton. A buffer headrest is installed on the top of the top seat.

[0006] Further defined, the lightweight skeleton and the two assembly blocks are integrally formed. A number of hollow holes are provided on the lightweight skeleton. Such a structural design facilitates the installation of the lightweight skeleton, and by providing hollow holes on the lightweight skeleton, the structural lightweighting is achieved.

[0007] Further defined, a positioning plug is fixedly installed at the top of the lightweight skeleton, and a positioning slot is provided at the bottom of the top seat corresponding to the positioning plug. Such a structural design enables the top seat to be positioned and installed when installing the top seat, preventing the top seat from being installed in the wrong direction.

[0008] Further defined, limiting pressure blocks are installed on both sides of the top seat. A through hole is provided at the center of the limiting pressure block. Countersunk holes are provided on both sides of the support side plate corresponding to the through hole. A positioning bolt is installed in the countersunk hole on one side. The other side of the positioning bolt passes through the through hole and is connected with a locking nut, and the locking nut is installed in the countersunk hole on the other side. Such a structural design, after installing the top seat between the support side plates on both sides, installs the limiting pressure blocks on both sides of the top seat into the assembly grooves of the support side plates. Then insert a positioning bolt from the countersunk hole on one side, so that the positioning bolt passes through the through hole of the limiting pressure block and extends out from the countersunk hole on the other side. Finally, lock the locking nut on the extended positioning bolt so that the locking nut is installed in the countersunk hole, thereby completing the limiting and fixed installation of the top seat, further ensuring the fixation of the lightweight skeleton and improving the subsequent stable use effect.

[0009] Further defined, both the breathable support plate and the limiting frame are arranged between the two assembly blocks, and the backrest mesh surface and the back plate are installed between the support side plates on both sides. Such a structural design facilitates limiting installation and improves the subsequent use effect.

[0010] The beneficial effects of the present utility model are as follows: By directly inserting the lightweight skeleton into the assembly groove on the support side plate, the installation of the seat backrest is completed. Its installation method is greatly simplified. Moreover, by opening hollow holes on the lightweight skeleton, lightweight can be effectively achieved and the weight is greatly reduced. Then, with the cooperation of the breathable support plate, while achieving the effects of ventilation and support, it can also strengthen the strength of the seat back plate, making it not easily damaged. At the same time, under the effects of the backrest mesh surface, the breathable foam layer and the ventilation grooves on the back plate, the seat back plate has good breathability, making the ride more comfortable.

[0019] Preferably, the lightweight skeleton 5 and the two assembly blocks 4 are integrally formed, and a plurality of hollow holes 16 are provided on the lightweight skeleton 5. Such a structural design facilitates the installation of the lightweight skeleton 5, and by providing the hollow holes 16 on the lightweight skeleton 5, the structural lightweight is achieved. In fact, other structural shapes of the lightweight skeleton 5 can also be considered according to specific situations.

[0020] Preferably, a positioning plug block 17 is fixedly installed on the top of the lightweight skeleton 5, and a positioning slot 18 is provided at the bottom of the top seat 14 corresponding to the positioning plug block 17. Such a structural design enables the top seat 14 to be positioned and installed when installing the top seat 14, preventing the top seat 14 from being installed reversely. In fact, other positioning and installation structural shapes of the lightweight skeleton 5 and the top seat 14 can also be considered according to specific situations.

[0021] Preferably, limiting pressure blocks 19 are installed on both sides of the top seat 14. A through hole 20 is provided at the center of the limiting pressure block 19. Counterbore holes 21 are provided on both sides of the support side plate 2 corresponding to the through hole 20. A positioning bolt 22 is installed in one of the counterbore holes 21. The other side of the positioning bolt 22 passes through the through hole 20 and is connected with a locking nut 23. The locking nut 23 is installed in the other counterbore hole 21. After the top seat 14 is installed between the support side plates 2 on both sides with such a structural design, the limiting pressure blocks 19 on both sides of the top seat 14 are installed into the assembly grooves 3 of the support side plates 2. Then, the positioning bolt 22 is inserted from one of the counterbore holes 21, so that the positioning bolt 22 passes through the through hole 20 of the limiting pressure block 19 and extends out from the other counterbore hole 21.

In fact, other installation structural shapes of the breathable support plate 6, the limiting frame 7, the backrest mesh surface 9 and the back plate 11 can also be considered according to specific situations.

[0023] In this embodiment, when the driver or passenger is sitting, the back of the driver or passenger leans against the backrest mesh surface 9, and the weight of the human body will squeeze the breathable foam layer 8 in the limiting frame 7, causing the breathable foam layer 8 to deform and fit the back of the driver or passenger, making it more comfortable when sitting. The heat on the back of the driver or passenger can dissipate heat and breathe through the breathable holes 10 on the backrest mesh surface 9, and cooperate with the breathable foam layer 8, the breathable support plate 6, the lightweight skeleton 5 and the breathable grooves 12 on the back plate 11, so that the air permeability of the entire seat backrest is good, and the driver or passenger is more comfortable when sitting. Moreover, under the effect of the mesh 13, impurities can be prevented from entering the lightweight skeleton 5 and affecting the breathable foam layer 8.

[0024] At the same time, the lightweight skeleton 5 is matched with the assembly grooves 3 on the support side plates 2 through the assembly blocks 4 on both sides. The lightweight skeleton 5 is directly inserted into the assembly grooves 3 on the support side plates 2 to complete the installation of the seat backrest. Its installation method is greatly simplified. And through holes 16 are opened on the lightweight skeleton 5, which can effectively achieve lightweight and greatly reduce the weight. Then, with the cooperation of the breathable support plate 6, while achieving the effect of breathable support, it can also strengthen the strength of the seat backrest and make it not easily damaged.

[0025] The above embodiments are only used to exemplarily illustrate the principles and effects of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present utility model should still be covered by the claims of the present utility model.
