Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts processing, in particular to a rotation buffer mechanism for an automobile rear armrest box. Background Art
[0002] The rear armrest of a car is an important part of the car seat. It is mainly designed to meet the comfort of the rear passengers. It is used to place their arms so that they can get an effective rest, avoid numbness and stiffness, and reduce riding fatigue. Water cups can also be placed on the armrest.
[0003] In general, the rear armrest box is stored inside the rear seat. When needed, it can be rotated out from the inside of the seat. Due to the weight of the armrest box itself, the armrest box rotates out at a fast speed, and the bracket inside the armrest box collides with the seat bracket. Over time, it will cause the armrest box structure or the seat structure to deform, resulting in the armrest box being installed loosely. In addition, with the popularization of smart cars, the armrest box has more and more functions, so there are more and more electronic circuits inside the armrest box. If the armrest box is often collided, it will affect the stability of the internal electronic circuit connection, causing electronic circuit failure, affecting the normal operation of the corresponding functions of the armrest box.
[0004] In response to the above problems, this utility model document proposes a rotation buffer mechanism for the rear armrest box of an automobile. Utility Model Content
[0005] The utility model provides a rotation buffer mechanism for an armrest box in the rear of an automobile, which reduces the impact force of the armrest box rotation and improves the stability of the armrest box installation structure.
[0006] The utility model provides the following technical solutions:
[0007] A rotation buffer mechanism for a rear armrest box of a car includes an armrest box bracket, the armrest box bracket includes a rotation bracket and a fixed bracket, the rotation bracket includes two side panels, one end of the two side panels is connected and fixed by a connecting plate, and a rotating shaft is provided through the other end, a reinforcing plate is further provided between the two side panels, a gas spring is provided between the reinforcing plate and the rotating shaft, and the fixed bracket is fixedly provided at both ends of the rotating shaft.
[0008] Furthermore, a ball head connector is provided at one end of the gas spring, and a rod end joint bearing is provided at the other end.
[0009] Furthermore, a connecting ear plate is fixedly connected to the rotating shaft, a connecting hole is opened on the connecting ear plate, and the connecting ear plate is rotatably connected to the rod end joint bearing.
[0010] Furthermore, a mounting hole is provided on the connecting ear plate, and the connecting ear plate is sleeved on the rotating shaft through the mounting hole and fixedly connected to the rotating shaft by welding.
[0011] Furthermore, a mounting and positioning plate is provided between the reinforcing plate and the side plate. The mounting and positioning plate is a "Z"-shaped structure. A ball head seat that cooperates with the ball head connector is provided on the mounting and positioning plate.
[0012] In the utility model, the fixed bracket is connected to the car seat bracket. When the armrest box is folded, the gas spring on the rotating bracket is in a contracted state. When the armrest box is lowered, the gas spring is pulled at the same time. The elastic force of the gas spring offsets part of the gravity of the rotating bracket, so that the rotating bracket rotates slowly and smoothly, thereby reducing the impact force of the rotating bracket during rotation, thereby ensuring the stability of the installation structure of the armrest box bracket on the car seat bracket, and reducing the impact on the internal circuit of the armrest box, thereby ensuring the normal use of the armrest box.

[0021] Example:
[0022] Reference Figure 1 As shown, a rotation buffer mechanism for the rear armrest box of a car includes an armrest box bracket, which includes a rotating bracket 1 and a fixed bracket 2. The rotating bracket 1 includes two side panels 101. One end of the two side panels 101 is connected and fixed by a connecting plate 102, and a rotating shaft 3 is provided at the other end. A reinforcing plate 103 is also provided between the two side panels 101, and a gas spring 4 is provided between the reinforcing plate 103 and the rotating shaft 3. The fixed bracket 2 is fixedly provided at both ends of the rotating shaft 3.
[0023] The fixing bracket 2 is installed on the rear seat bracket of the car, and the rotating shaft 3 is fixed on the fixing bracket 2, and one end of the two side panels 101 is fixed together by a connecting plate 102, and the stability of the splicing structure of the two side panels 101 is improved by the reinforcing plate 103. The side panel 101 is rotatably set on the rotating shaft 3. By rotating the side panel 101, the gas spring 4 is driven to rotate together, and the gas spring 4 will be stretched when rotating. The elastic force of the gas spring 4 offsets part of the weight of the rotating bracket 1, so that the rotating bracket 1 rotates slowly and smoothly, thereby reducing the impact force of the rotating bracket 1 when rotating, reducing the collision between the rotating bracket 1 and the car seat bracket, and having a protective effect on the rotating bracket 1 and the car bracket. At the same time, it ensures the stability of the connection structure between the rotating bracket 1 and the car bracket, and improves the service life of the armrest box.
[0024] A ball joint 6 is provided at one end of the gas spring 4 , and a rod end joint bearing 7 is provided at the other end.
[0025] The ball joint 6 and the rod end joint bearing 7 facilitate the installation of the gas spring 4 and ensure that the gas spring 4 can rotate together with the side plate 101.
[0026] A connecting ear plate is also fixedly connected to the rotating shaft 3 , a connecting hole is opened on the connecting ear plate, and the connecting ear plate is rotatably connected to the rod end joint bearing 7 .
[0027] The connecting ear plate is fixed on the rotating shaft 3 so that the side plate 101 can stretch the gas spring 4 while rotating on the rotating shaft 3, thereby ensuring the normal operation of the gas spring 4.
[0028] The connecting ear plate is provided with a mounting hole, and the connecting ear plate is sleeved on the rotating shaft 3 through the mounting hole and is fixedly connected to the rotating shaft 3 by welding.
[0029] The mounting hole is put on the rotating shaft 3, and then the connection is welded to ensure the stability of the connection structure between the connecting ear plate and the rotating shaft 3, and to ensure that the connecting ear plate will not rotate on the rotating shaft 3. When the gas spring 4 rotates, the position of one end connected to the connecting ear plate is fixed, and the gas spring 4 can be stretched, so that the gas spring 4 can provide elastic force to the rotating bracket 1.
[0030] A mounting and positioning plate 5 is provided between the reinforcing plate 103 and the side plate 101 . The mounting and positioning plate 5 is a “Z”-shaped structure. A ball head seat 8 that matches the ball head connector 6 is provided on the mounting and positioning plate 5 .
[0031] The installation of the ball head seat 8 is facilitated by installing the positioning plate 5 , and the ball head connector 6 at one end of the gas spring 4 is positioned by the ball head seat 8 , so as to facilitate the installation of the gas spring 4 .
[0032] During assembly, a connecting ear plate is sleeved on the rotating shaft 3 and the connection is welded and fixed. The positioning plate 5 is fixedly installed on the reinforcing plate 103 and the side plate 101, and then the ball head seat 8 is fixed to the installation positioning plate 5. The gas spring 4 is provided with a ball head connector 6 at one end which is matched and fixed with the ball head seat 8, and the other end is connected to the connecting ear plate and the rod end joint bearing 7 by a bolt. The fixed bracket 2 is fixed on the rear seat bracket of the car, and the rotating bracket 1 is embedded in the rear seat bracket of the car.
[0033] During use, when the armrest box is folded, the gas spring 4 is in a retracted state. When the armrest box is opened, the user pulls the rotating bracket 1 to rotate, while the fixed bracket 2 remains stationary, then the rotating shaft 3 does not move, and the connecting ear plate on the rotating shaft 3 also does not move. The rotating bracket 1 rotates on the rotating shaft 3, and when one end of the gas spring 4 rotates with the rotating bracket 1, the position of the other end does not change. Due to the length of the connecting ear plate, the gas spring 4 will be stretched, so that the gas spring 4 generates a contraction elastic force acting on the rotating bracket 1, thereby offsetting part of the gravity of the rotating bracket 1, making the rotating bracket 1 rotate at a stable speed, thereby reducing the impact force generated by the rotating bracket 1 and the rear seat bracket of the car after it is rotated into place, ensuring the stability of the structure directly connected to the armrest box bracket and the rear seat of the car, while also avoiding damage to the electronic circuits in the armrest box caused by collision.
[0034] The utility model has the advantages of simple structure, convenient use and suitable for promotion.
[0035] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The embodiments of the present utility model and the features of the embodiments can be combined with each other unless there is a conflict.
