Abstract
Description
Technical Field

[0002] A door limiter is an auxiliary component connecting an automobile door and the vehicle body, and its main function is to limit the opening angle of the door. The tailgate limiter mounting bracket is an important part to keep the limiter stably connected. During the use of the vehicle, the door limiter helps prevent the door from opening or closing by itself when the vehicle body is tilted.

[0021] In order to make the purpose and advantages of the present utility model clearer, the following specifically describes the present utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the protection scope of the specific request of the present utility model.
[0022] As Figure 1 shown, a tailgate limiter mounting bracket for a small car includes a limiting arm 1. A second rotating shaft 4 is provided at one end of the limiting arm 1. Second support frames 5 are respectively provided at both ends of the second rotating shaft 4. Second fixing seats 6 are provided at the other ends of the two groups of support frames. A limiting device 2 is provided on the limiting arm 1. An anti-collision device 3 is provided at the other end of the limiting arm 1;
[0023] Among them, the limiting device 2 includes a spring 203 and a roller 207. The spring 203 always maintains pressure on the roller 207. The anti-collision device 3 includes a baffle 303 and an elastic member 302. The elastic member 302 is used to control the reset of the baffle 303.
[0024] In this embodiment, the limiter is first installed. Through the through hole opened in the second fixing seat 6, the second fixing seat 6 is fixed to the vehicle frame, so that the second support frame 5 and the second rotating shaft 4 are fixed. Through the through hole opened in the support plate 201 of the limiting device 2, the limiter is fixed to the vehicle door. When the vehicle door is opened or closed, the vehicle door rotates by a certain angle. Due to the rotation of the vehicle door, the limiting arm 1 rotates, so that the limiting arm 1 rotates around the second rotating shaft 4. At this time, due to the rotation of the limiting arm 1, the limiting arm 1 in the limiting device 2 moves, so that the roller 207 rolls along the limiting arm 1. When passing through the groove on the limiting arm 1, due to the elastic force of the spring 203, the first fixing seat 204 moves downward, so that the first support frame 205, the first rotating shaft 206 and the roller 207 on the first fixing seat 204 move downward together, so that the roller 207 always has an extrusion force on the limiting arm 1. When preparing to move towards the convex part, a certain pushing force or pulling force needs to be provided manually, so that the limiting arm 1 has enough force to squeeze the roller 207, so that the roller 207 moves upward. At this time, due to the extrusion of the limiting arm 1, the spring 203 is squeezed and deformed, so that the limiting arm 1 can reach the next stage better. In this process, since only the roller 207 contacts the limiting arm 1, the noise between metals is reduced; when the vehicle door is opened too wide, the rotation angle of the limiting arm 1 is too large, resulting in the limiting arm 1 inside the vehicle door being close to the vehicle door. At this time, the fixing plate 301 in the anti-collision device 3 approaches the housing 202, so that the baffle 303 squeezes the housing 202. Due to the action of the elastic member 302, the fixing plate 301 cannot squeeze the housing 202. And at this time, after the baffle 303 squeezes the housing 202, due to the pulling force of the elastic member 302, the baffle 303 moves away from the housing 202, playing a buffering role, thus completing a series of operations.
[0025] As Figure 2 and Figure 3 shown, the limiting device 2 includes a support plate 201. The support plate 201 is slidably connected to the limiting arm 1. One side of the support plate 201 is fixedly connected to a housing 202. Above the housing 202, a spring 203 is fixedly connected. Below the spring 203, a first fixing seat 204 is fixedly connected. At both ends below the first fixing seat 204, first support frames 205 are respectively fixedly connected. The lower ends of the two groups of first support frames 205 are fixedly connected to a first rotating shaft 206. A roller 207 is rotatably connected to the first rotating shaft 206, and the roller 207 is in rolling connection with the limiting arm 1. A structure symmetrical to the upper part inside the housing 202 is provided at the lower end inside the housing 202.
[0026] In the above - mentioned manner, when opening or closing the vehicle door, the vehicle door rotates by a certain angle. Due to the rotation of the vehicle door, the limiting arm 1 rotates, causing the limiting arm 1 to rotate around the second rotating shaft 4. At this time, due to the rotation of the limiting arm 1, the limiting arm 1 in the limiting device 2 moves, causing the roller 207 to roll along the limiting arm 1. When passing through the groove on the limiting arm 1, due to the elastic force of the spring 203, the first fixed seat 204 moves downward, causing the first support frame 205, the first rotating shaft 206, and the roller 207 on the first fixed seat 204 to move downward together. As a result, the roller 207 always exerts a squeezing force on the limiting arm 1. When preparing to move towards the convex part, a certain pushing force or pulling force needs to be provided manually, so that the limiting arm 1 has sufficient force to squeeze the roller 207, causing the roller 207 to move upward. At this time, due to the squeezing of the limiting arm 1, the spring 203 is squeezed and deformed, enabling the limiting arm 1 to better reach the next stage. In this process, since only the roller 207 is in contact with the limiting arm 1, the noise between metals is reduced.
[0027] As Figure 2 shown, the anti - collision device 3 includes a fixing plate 301. The fixing plate 301 is fixedly connected to the limiting arm 1. Elastic members 302 are fixed at both ends of the fixing plate 301, and a baffle 303 is fixed to the ends of the elastic members 302.
[0028] In the above - mentioned manner, when the vehicle door is opened too wide, the limiting arm 1 rotates by too large an angle, causing the limiting arm 1 inside the vehicle door to be close to the vehicle door. At this time, the fixing plate 301 in the anti - collision device 3 approaches the housing 202, causing the baffle 303 to squeeze the housing 202. Due to the action of the elastic member 302, the fixing plate 301 cannot squeeze the housing 202. At this time, after the baffle 303 squeezes the housing 202, due to the pulling force of the elastic member 302, the baffle 303 moves away from the housing 202, playing a buffering role.
[0029] As Figure 2 shown, a through - hole is opened at one end of the limiting arm 1 close to the second base. The second rotating shaft 4 is arranged in the through - hole opened by the limiting arm 1. The second rotating shaft 4 is rotatably connected to the limiting arm 1. Both ends of the second rotating shaft 4 are respectively rotatably connected to two groups of second support frames 5. The second support frames 5 are fixedly connected to the second fixed seat 6, and the second fixed seat 6 is provided with a fixing through - hole.
[0030] In the above - mentioned manner, the through - hole opened at one end of the limiting arm 1 close to the second base is for the limiting arm 1 to rotate around the second rotating shaft 4 during the rotation process. And the through - hole opened in the second fixed seat 6 enables the second fixed seat 6 to be fixed to the vehicle frame, enabling the second support frame 5 and the second rotating shaft 4 to be fixed, so that the limiting arm 1 does not move during rotation.
[0031] As Figure 3 shown, through holes are formed at both ends of the support plate 201, and a square through hole is formed in the middle of the support plate 201. The limiting arm 1 is arranged in the square through hole formed in the middle of the support plate 201, and the support plate 201 is slidably connected to the limiting arm 1.
[0032] In the above manner, the through holes formed at both ends of the support plate 201 can fix the limiting device 2 on the vehicle door, so that the limiting arm 1 can move better.
[0033] As Figure 3 shown, a cavity is formed inside the housing 202, and through holes are formed on both sides of the housing 202. The limiting arm 1 is arranged in the through holes formed in the housing 202, and the spring 203, the first fixing seat 204, the first support frame 205, the first rotating shaft 206 and the roller 207 are arranged in the cavity formed in the housing (202).
[0034] In the above manner, when the vehicle door is opened or closed, the vehicle door rotates by a certain angle. Due to the rotation of the vehicle door, the limiting arm 1 rotates, so that the limiting arm 1 rotates around the second rotating shaft 4. At this time, due to the rotation of the limiting arm 1, the limiting arm 1 in the limiting device 2 moves, so that the roller 207 rolls along the limiting arm 1. When passing through the groove on the limiting arm 1, due to the elastic force of the spring 203, the first fixing seat 204 moves downward, so that the first support frame 205, the first rotating shaft 206 and the roller 207 on the first fixing seat 204 move downward together, so that the roller 207 always has an extrusion force on the limiting arm 1. When preparing to move to the protrusion, a certain pushing force or pulling force needs to be provided manually, so that the limiting arm 1 has enough force to extrude the roller 207, so that the roller 207 moves upward. At this time, due to the extrusion of the limiting arm 1, the spring 203 is extruded and deformed, so that the limiting arm 1 can reach the next stage better.
[0035] The working principle of this utility model is as follows: First, install the stopper. Fix the second fixing seat 6 on the vehicle frame through the through hole opened in the second fixing seat 6, so that the second support frame 5 and the second rotating shaft 4 are fixed. Fix the stopper on the car door through the through hole opened in the support plate 201 in the limiting device 2. When opening or closing the car door, the car door rotates by a certain angle. Due to the rotation of the car door, the limiting arm 1 rotates, so that the limiting arm 1 rotates around the second rotating shaft 4. At this time, due to the rotation of the limiting arm 1, the limiting arm 1 in the limiting device 2 moves, so that the roller 207 rolls along the limiting arm 1. When passing through the groove on the limiting arm 1, due to the elastic force of the spring 203, the first fixing seat 204 moves downward, so that the first support frame 205, the first rotating shaft 206 and the roller 207 on the first fixing seat 204 move downward together, so that the roller 207 always has an extrusion force on the limiting arm 1. When preparing to move to the convex part, a certain pushing force or pulling force needs to be provided manually, so that the limiting arm 1 has enough force to squeeze the roller 207, so that the roller 207 moves upward. At this time, due to the extrusion of the limiting arm 1, the spring 203 is squeezed and deformed, so that the limiting arm 1 can better reach the next stage. In this process, since only the roller 207 contacts the limiting arm 1, the noise between metals is reduced; when the car door is opened too wide, the rotation angle of the limiting arm 1 is too large, resulting in the limiting arm 1 inside the car door being close to the car door. At this time, the fixing plate 301 in the anti-collision device 3 approaches the housing 202, so that the baffle 303 squeezes the housing 202. Due to the action of the elastic member 302, the fixing plate 301 cannot squeeze the housing 202. And at this time, after the baffle 303 squeezes the housing 202, due to the pulling force of the elastic member 302, the baffle 303 moves away from the housing 202, playing a buffering role, thus completing a series of operations.
[0036] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
