Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an anti-loosening connector for automobile bodies. Background Technology

[0002] The car body is the mounting base for all body parts. It usually refers to the rigid spatial structure composed of the main load-bearing elements such as longitudinal and transverse beams and pillars, as well as the plates connected to them. During the assembly of a car, various accessories such as pillars, door sills, floor, roof, and doors are installed on the car body. When installing the doors, connectors are needed to connect the doors to the car body.

[0003] In existing technology, the connector mainly consists of a fixed seat connected to the car body, a movable seat connected to the door, and a rotating shaft that allows the two connecting seats to rotate relative to each other. During assembly, the fixed seat is first fixed to the preset mounting position on the car body by bolts or welding, and then the movable seat is mated and tightened to the connection point on the inside of the door. Finally, the door opening and closing function is realized by the rotation of the rotating shaft.

[0004] However, during operation, when a passenger opens the car door, the door opens to the preset limit under the force of the push. At this point, the movable seat will collide hard with the limiting structure of the fixed seat. The impact force generated by the hard collision will be transmitted to the fit gap between the pivot and the connecting seat, as well as the connection between the fixed seat and the car body, and between the movable seat and the car door. Under long-term repeated impacts, the connecting bolts are prone to loosening, which reduces the installation firmness of the connecting seat.

[0005] Therefore, an anti-loosening connector for automobile body is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the connecting bolts of the car body connector are prone to loosening when passengers open the car door, and to propose a car body anti-loosening connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an anti-loosening connector for an automotive body, comprising a fixed base, a fixed plate fixedly connected to the surface of the fixed base, a rotating shaft rotatably connected inside the fixed plate, connecting plates fixedly connected to both ends of the rotating shaft, the connecting plates slidably connected to the fixed plate, a movable seat fixedly connected to the surface of the connecting plate, a fixed ring fixedly connected to the surface of the fixed base, a slider slidably connected to the inner circumferential surface of the fixed ring, a screw threadedly connected to the slider, an arc-shaped plate rotatably connected to one end of the screw, a spring fixedly connected between the fixed base and the slider, and a pressure block fixedly connected to the circumferential surface of the rotating shaft.

[0008] The effect achieved by the above components is as follows: when a passenger opens the car door, the pressure block will exert a continuously increasing thrust on the arc plate, and the spring will be gradually compressed. During the compression process, the spring will generate a reverse elastic force. This elastic force can transform the hard collision when the traditional connector opens the car door into the elastic buffer of the spring, which greatly reduces the impact force generated by the collision. This prevents the bolts at the connection between the fixed seat and the housing, and between the movable seat and the car door from loosening due to repeated violent impacts, and effectively ensures the overall installation firmness of the connector.

[0009] Preferably, the inner circumferential surface of the fixing ring is provided with a groove, and the circumferential surface of the slider is fixedly connected with a protrusion, and the groove and the protrusion are slidably connected.

[0010] The effect achieved by the above components is that the sliding of the slider will cause the protrusion to slide along the inner wall of the groove, and the cooperation between the protrusion and the groove can prevent the slider from coming off the inner circumference of the fixing ring.

[0011] Preferably, a rotating plate is fixedly connected to the circumferential surface of the screw.

[0012] The effect achieved by the above components is that the rotating plate can easily adjust the position of the arc-shaped plate by rotating the screw.

[0013] Preferably, a limiting plate is fixedly connected to the surface of the arc-shaped plate, and the limiting plate is slidably connected to the fixed plate.

[0014] The effect achieved by the above components is that the limiting plate can slide along the surface of the fixed plate following the arc plate, and the limiting plate can prevent the arc plate from rotating with the screw.

[0015] Preferably, the circumferential surface of the pressing block is provided with a plurality of strip grooves.

[0016] The effect achieved by the above components is that the strip groove can increase the friction between the pressure block and the arc plate, thereby improving the deceleration effect.

[0017] Preferably, a shield is fixedly connected to the surface of the fixing base, the shield is fixedly connected to the fixing plate, the surface of the fixing plate has a locking hole, the inner wall of the locking hole is slidably connected to a locking plate, and the surface of the locking plate is fixedly connected to a baffle.

[0018] The above components achieve the following effect: the shield and baffle work together to effectively block dust and other impurities in the external environment, preventing the screw from getting stuck due to the accumulation of impurities.

[0019] Preferably, a plurality of elastic strips are fixedly connected to the surface of the card plate, and the elastic strips abut against the inner wall of the card hole.

[0020] The effect achieved by the above components is that the elastic strip will deform and press against the inner wall of the locking hole, so as to realize the quick reinstallation of the baffle.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting components such as a fixing ring, slider, screw, arc plate, spring, and pressure block, when a passenger opens the car door, the pressure block will generate a continuously increasing thrust on the arc plate, and the spring will be gradually compressed. During the compression process, the spring will generate a reverse elastic force. This elastic force can transform the hard collision when the car door is opened by the traditional connector into the elastic buffer of the spring, which greatly reduces the impact force generated by the collision. This prevents the bolts at the connection between the fixed seat and the housing, and between the movable seat and the car door from loosening due to repeated violent impacts, and effectively ensures the overall installation firmness of the connector.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-6As shown, this utility model provides an anti-loosening connector for an automotive body, including a fixed base 1, a fixed plate 2 fixedly connected to the surface of the fixed base 1, a rotating shaft 3 rotatably connected inside the fixed plate 2, connecting plates 4 fixedly connected to both ends of the rotating shaft 3, the connecting plates 4 slidably connected to the fixed plate 2, a movable seat 5 fixedly connected to the surface of the connecting plate 4, a fixed ring 6 fixedly connected to the surface of the fixed base 1, a slider 7 slidably connected to the inner circumferential surface of the fixed ring 6, a screw 8 internally threaded to the slider 7, and an arc-shaped plate 9 rotatably connected to one end of the screw 8. The fixed base 1 and the slider 7 are fixedly... A spring 10 is fixedly connected to the circumferential surface of the rotating shaft 3, and a pressure block 11 is fixedly connected to it. When the passenger opens the door, the pressure block 11 will exert a continuously increasing thrust on the arc plate 9, and the spring 10 will be gradually compressed. During the compression process, the spring 10 will generate a reverse elastic force. This elastic force can transform the hard collision when the traditional connector opens the door into the elastic buffer of the spring 10, which greatly reduces the impact force generated by the collision. This prevents the bolts connecting the fixed seat 1 and the housing, and the movable seat 5 and the door from loosening due to repeated violent impacts, and effectively ensures the overall installation firmness of the connector.

[0027] like Figures 2-6 As shown, the inner circumferential surface of the fixed ring 6 has a groove 12, and the circumferential surface of the slider 7 is fixedly connected to a protrusion 13. The groove 12 and the protrusion 13 are slidably connected. When the slider 7 slides, it will drive the protrusion 13 to slide along the inner wall of the groove 12. The cooperation between the protrusion 13 and the groove 12 can prevent the slider 7 from coming off the inner circumferential surface of the fixed ring 6. The circumferential surface of the screw 8 is fixedly connected to a rotating plate 14. The rotating plate 14 can easily rotate the screw 8 to adjust the position of the arc plate 9. The surface of the arc plate 9 is fixedly connected to a limiting plate 15. The limiting plate 15 is slidably connected to the fixed plate 2. The limiting plate 15 can slide along the surface of the fixed plate 2 with the arc plate 9. The limiting plate 15 can prevent the arc plate 9 from rotating with the screw 8. The circumferential surface of the pressure block 11 has several strip grooves 16. The strip grooves 16 can increase the friction between the pressure block 11 and the arc plate 9 and improve the deceleration effect.

[0028] like Figure 2 , Figure 4 and Figure 6 As shown, a shield 17 is fixedly connected to the surface of the fixed base 1. The shield 17 is fixedly connected to the fixed plate 2. The surface of the fixed plate 2 is provided with a locking hole 18. A locking plate 19 is slidably connected to the inner wall of the locking hole 18. A baffle 20 is fixedly connected to the surface of the locking plate 19. The shield 17 and the baffle 20 work together to effectively block dust and other impurities in the external environment and prevent the screw 8 from getting stuck due to the accumulation of impurities. Several elastic strips 21 are fixedly connected to the surface of the locking plate 19. The elastic strips 21 abut against the inner wall of the locking hole 18. The elastic strips 21 will deform and press against the inner wall of the locking hole 18, so as to realize the quick reinstallation of the baffle 20.

[0029] The overall working principle is as follows: when a car door needs to be installed, the fixing seat 1 is first fastened to the preset mounting position of the car body by bolts or welding to ensure that the fixing seat 1 and the car body are stably connected. Then, the movable seat 5 is precisely aligned and fixed to the connection point on the inner side of the car door to complete the assembly of the car body and the car door. If a buffering effect is required during the opening of the car door, the rotating plate 14 on the circumference of the screw 8 can be rotated. With the help of the threaded engagement between the screw 8 and the slider 7, the arc plate 9 is pushed to move slowly towards the rotating shaft 3 until the arc plate 9 and the pressure block 11 on the circumference of the rotating shaft 3 form a preset gap. This gap can be adjusted according to the requirements of the limit angle of the car door opening of different models to achieve the best buffering effect. During the adjustment process, the limiting plate 15 will slide along the surface of the fixing plate 2 along with the arc plate 9. The limiting plate 15 can prevent the arc plate 9 from rotating with the screw 8.

[0030] When a passenger opens the car door, the door causes the movable seat 5 to rotate around the pivot 3. Simultaneously, the pivot 3 rotates, causing the connecting plates 4 at both ends to slide along the fixed plate 2. At the same time, the pressure block 11 on the circumferential surface of the pivot 3 gradually moves closer to the arc-shaped plate 9 as the pivot 3 rotates. When the door opening angle approaches the preset limit, the pressure block 11 first contacts the arc-shaped plate 9. Because the circumferential surface of the pressure block 11 has several grooves 16, these grooves increase the friction between the pressure block 11 and the arc-shaped plate 9, improving the deceleration effect. The pressure block 11 will generate a continuously increasing thrust on the arc plate 9. Under the action of the thrust, the arc plate 9 will drive the slider 7 to slide along the inner circumference of the fixed ring 6. The spring 10 will be gradually compressed. During the compression process, the spring 10 will generate a reverse elastic force. This elastic force can transform the hard collision when the traditional connector opens the car door into the elastic buffer of the spring 10, which greatly reduces the impact force generated by the collision. This will prevent the bolts of the fixed seat 1 and the housing, and the movable seat 5 and the car door from loosening due to repeated violent impacts, and effectively ensure the overall installation firmness of the connector.

[0031] When the car door is closed, the door will cause the movable seat 5 to rotate in the opposite direction. The rotating shaft 3 and the pressure block 11 will also rotate in the opposite direction synchronously. As the rotation angle changes, the pushing force of the pressure block 11 on the arc plate 9 will gradually disappear. At this time, the compressed spring 10 will return to its original shape under its own elastic force, and at the same time, it will drive the slider 7 and the arc plate 9 to reset together, eventually returning to the initial preset gap state. The sliding of the slider 7 will drive the protrusion 13 to slide along the inner wall of the groove 12. The cooperation between the protrusion 13 and the groove 12 can prevent the slider 7 from sliding out of the inner wall of the fixing ring 6. The circumferential surface protrudes, fully preparing for the buffer function when the car door is opened next time. In addition, the shield 17 and the baffle 20 work together to effectively block dust and other impurities in the external environment, preventing the screw 8 from getting stuck due to the accumulation of impurities. When it is necessary to rotate the rotating plate 14, simply pull the baffle 20 outward to drive the clamping plate 19 out of the clamping hole 18, and the baffle 20 can be removed. After maintenance, the clamping plate 19 is reinserted into the clamping hole 18, and the elastic strip 21 will deform and press against the inner wall of the clamping hole 18, realizing the quick reinstallation of the baffle 20.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
