Technical Field
[0001] This application relates to the field of automobile manufacturing, and in particular to a vehicle structure for a hood lock. Background Technology
[0002] In the modern automotive manufacturing industry, the hood lock is a core component for maintaining vehicle safety, and its performance directly affects the safety of passengers and the vehicle itself. During the manufacturing process, the hood lock typically uses a carrier to move and position itself between different production facilities.
[0003] However, existing carriers can only be used as simple placement fixtures, primarily serving as temporary support during the processing. When the carrier moves to different processing stations, the hatch lock needs to be transferred to the corresponding production mechanism, which not only reduces the processing efficiency of the hatch lock but also easily damages it.
[0004] For example, when riveting the main board and locating pin of the hood lock, the main board and locating pin need to be transferred from the carrier to the riveting mechanism. During the transfer process, relative misalignment can easily occur between the main board and the locating pin, causing the subsequent riveting process to be unable to proceed smoothly. This greatly affects the riveting quality and efficiency of the hood lock. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this application provides a vehicle structure for a front hatch lock that can assist in the riveting of the front hatch lock.
[0006] The vehicle structure provided in this application adopts the following technical solution:
[0007] A carrier structure for a front hatch lock includes a carrier body, on which multiple riveting posts are provided, and multiple riveting blocks are spaced apart on the periphery of each riveting post.
[0008] By adopting the above technical solution, when the front hatch lock is mounted on the vehicle body, the riveting pin can be inserted into the positioning pin. Pressure is applied to the riveting pin, and multiple riveting blocks can be squeezed into the positioning pin under pressure and riveted to the side wall of the positioning pin relative to the main board. In this way, the main board and the positioning pin can be riveted directly on the vehicle body without having to transfer them to the riveting mechanism, which effectively improves the riveting quality and efficiency of the front hatch lock.
[0009] In one specific implementation, one side of the vehicle body has a bearing surface, the rivet block is conical, and the height of the rivet block in the radial direction of the rivet post gradually increases in the direction away from the bearing surface.
[0010] By adopting the above technical solution, the riveting block can rivet the positioning pin to the main board by gradually increasing its height as the riveting pin extends into the positioning pin. This not only results in high riveting efficiency but also avoids damage to the positioning pin.
[0011] In one specific implementation scheme, the vehicle body is provided with a plurality of clearance holes, each of which corresponds to a plurality of riveting posts, and each of the riveting posts is slidably inserted into the corresponding clearance hole.
[0012] By adopting the above technical solution, the riveting column can drive multiple riveting blocks to be accommodated in or out of the clearance hole during its sliding process, so as to complete the relative riveting of the main board and the positioning pin according to the specific processing process, and prevent the riveting blocks from being continuously exposed on the bearing surface, thus interfering with the normal loading of the front hatch lock.
[0013] In one specific implementation, a spring is sleeved on the end of the rivet post away from the bearing surface, and the spring is connected to the side of the carrier body opposite to the bearing surface.
[0014] By adopting the above technical solution, after riveting is completed, the multiple riveting blocks squeezed into the positioning pin can be reset under the action of the spring, which facilitates the subsequent relative disassembly of the front hatch lock and the vehicle body.
[0015] In one specific implementation, a guide sleeve is internally connected in the clearance hole, the riveting post includes a post body passing through the guide sleeve and a washer located at the end of the post body away from the bearing surface, and the two ends of the spring are respectively connected to the guide sleeve and the washer.
[0016] In one specific implementation, the riveting post further includes a bushing annularly disposed on the post body. The bushing is housed in the guide sleeve and has a clearance fit with the guide sleeve. A limiting ring is provided inside the end of the guide sleeve away from the bearing surface, and the inner diameter of the limiting ring is smaller than the outer diameter of the bushing.
[0017] By adopting the above technical solution, the limiting ring can limit the riveting post, preventing the riveting post from dislodging from the clearance hole and affecting the riveting process of the riveting block to the front hatch lock.
[0018] In one specific implementation, the plurality of rivet blocks are spaced apart on one side of the bushing near the bearing surface.
[0019] In one specific implementation scheme, an assembly area and a riveting area are respectively arranged at both ends of the bearing surface, the multiple riveting posts are arranged in the riveting area, and multiple limiting blocks are also arranged in the riveting area.
[0020] By adopting the above technical solution, the assembly and riveting processes of the front hatch lock can be carried out in the assembly area and the riveting area respectively, preventing the riveting block from interfering with the assembly process of the front hatch lock.
[0021] In one specific implementation, multiple positioning posts are provided in the assembly area.
[0022] By adopting the above technical solution, multiple positioning pins can be supported at the bottom of the front hatch lock during the assembly process, preventing the front hatch lock from moving during the assembly process.
[0023] In one specific implementation scheme, a transport block is provided on each side of the bearing surface, and the transport block is provided with a transport port.
[0024] By adopting the above technical solution, the handling mechanism can move the vehicle through the handling port, preventing the vehicle from falling off during the handling process.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] When the front hatch lock is mounted on the vehicle body, the rivet pin can be inserted into the positioning pin. Pressure is applied to the rivet pin, and multiple rivet blocks can be squeezed into the positioning pin under pressure and the side wall of the positioning pin is riveted to the main board. In this way, the main board and the positioning pin can be riveted directly on the vehicle body without having to transfer them to the riveting mechanism, which effectively improves the riveting quality and efficiency of the front hatch lock.

Detailed Implementation
[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] See Figure 1-3 As shown, a vehicle structure for a front hatch lock is illustrated. In conjunction with... Figure 1 As shown, the hood lock includes a main board 100 and three mounting holes 101 on the main board 100. A hollow positioning pin 102 is inserted into each mounting hole 101, and three riveting interfaces 103 are also provided on the peripheral wall of each mounting hole 101.
[0034] In this embodiment, as Figure 1-2 As shown, the vehicle structure includes a vehicle body 1, on which three riveting posts 2 are provided, and three riveting blocks 3 are spaced apart on the periphery of the riveting posts 2. The three riveting posts 2 are used to pass through the three positioning pins 102 respectively, and the three riveting blocks 3 correspond one-to-one with the three riveting interfaces 103 and are used to press the side walls of the positioning pins 102 into the three riveting interfaces 103.
[0035] Specifically, when the hatch lock is mounted on the vehicle body 1, the rivet pin 2 can be inserted into the positioning pin 102. Subsequently, the vehicle body 1 is lifted upwards by the lifting mechanism, while the hatch lock is pressed down by the clamping mechanism. Under the lifting force of the lifting mechanism, the rivet pin 2 slides into the positioning pin 102. The three rivet blocks 3 are pushed into the positioning pin 102 by the rivet pin 2. During this process, the parts of the inner wall of the positioning pin 102 that abut against the three rivet blocks 3 are pressed into the three riveting interfaces 103, thus completing the relative riveting of the positioning pin 102 and the main board 100. In this way, the main board 100 and the positioning pin 102 can be directly riveted on the vehicle body 1, without needing to be transferred to the riveting mechanism, effectively improving the riveting quality and efficiency of the hatch lock.
[0036] Both the lifting mechanism and the clamping mechanism can be accomplished using existing equipment. For example, the lifting mechanism can be a lifting cylinder, and the clamping mechanism can be a clamping cylinder. The specific structure and principle will not be elaborated here.
[0037] In this embodiment, combined with Figure 2-3 As shown, one side of the carrier body 1 has a bearing surface 1a, and the riveting block 3 is pyramidal in shape. The height of the riveting block 3 in the radial direction of the riveting post 2 gradually increases in the direction away from the bearing surface 1a. The riveting block 3 can rivet the positioning pin 102 to the main board 100 by its gradually increasing height as the riveting post 2 extends into the positioning pin 102. This not only has high riveting efficiency but also avoids damage to the positioning pin 102.
[0038] In this embodiment, the carrier body 1 has three clearance holes 4, which correspond one-to-one with three riveting posts 2. Each riveting post 2 is slidably inserted into the corresponding clearance hole 4. A spring 5 is sleeved on the end of the riveting post 2 away from the bearing surface 1a, and the spring 5 is connected to the side of the carrier body 1 away from the bearing surface 1a.
[0039] The riveting post 2 can drive multiple riveting blocks 3 to be accommodated in or out of the clearance hole 4 during its sliding process, so as to complete the relative riveting of the main board 100 and the positioning pin 102 according to the specific processing process, and prevent the riveting blocks 3 from being continuously exposed on the bearing surface 1a and interfering with the normal loading of the front hatch lock; after the riveting is completed, the multiple riveting blocks 3 squeezed into the positioning pin 102 can be reset under the action of the spring 5, which facilitates the subsequent relative disassembly of the front hatch lock and the vehicle body 1.
[0040] In this embodiment, a guide sleeve 6 is connected inside the clearance hole 4, and the riveting post 2 includes a post 2a passing through the guide sleeve 6 and a washer 2b located at the end of the post 2a away from the bearing surface 1a. The two ends of the spring 5 are respectively connected to the guide sleeve 6 and the washer 2b.
[0041] The riveting post 2 also includes a bushing 2c annularly disposed on the post body 2a. The bushing 2c is located in the middle of the post body 2a and is housed in the guide sleeve 6 with a clearance fit. Three riveting blocks 3 are spaced apart on the periphery of the end of the bushing 2c closest to the bearing surface 1a. A limiting ring 7 is provided inside the end of the guide sleeve 6 away from the bearing surface 1a. The inner diameter of the limiting ring 7 is smaller than the outer diameter of the bushing 2c. The limiting ring 7 can limit the riveting post 2, preventing the riveting post 2 from disengaging from the relief hole 4 and affecting the riveting process of the riveting blocks 3 to the front hatch lock.
[0042] In this embodiment, an assembly area and a riveting area are respectively arranged at both ends of the bearing surface 1a. Three riveting posts 2 are set in the riveting area, and two limiting blocks 8 are also set in the riveting area. Five positioning posts 9 are set in the assembly area. The five positioning posts 9 can be designed into different square or cylindrical shapes according to the specific positioning requirements of the front hatch lock. By dividing the bearing surface 1a into the assembly area and the riveting area, during assembly, the front hatch lock can be placed in the assembly area, and the positioning posts 9 are used to position and support the front hatch lock; during riveting, the front hatch lock can be placed in the riveting area, the limiting blocks 8 are used to limit the front hatch lock, and the riveting posts 2 are used to rivet the front hatch lock. This can avoid interference between the assembly and riveting processes of the front hatch lock.
[0043] In this embodiment, transport blocks 10 are respectively provided on both sides of the bearing surface 1a, and transport ports 10a are provided on the transport blocks 10. The transport mechanism can move the carrier through the transport ports 10a to prevent the carrier from falling during the transport process.
[0044] In this embodiment, two buffer blocks 11 are also provided at one end of the vehicle body 1.
[0045] The implementation principle of a vehicle structure according to an embodiment of this application is as follows:
[0046] The front hatch lock is mounted on the vehicle body 1. Then, the vehicle body 1 is lifted upward by the lifting mechanism, while the front hatch lock is pressed down by the clamping mechanism. Under the lifting force of the lifting mechanism, the rivet pin 2 slides into the positioning pin 102. The three rivet blocks 3 are squeezed into the positioning pin 102 by the rivet pin 2 and the side wall of the positioning pin 102 is pressed into the three rivet joints, thereby completing the relative riveting of the positioning pin 102 and the main board 100.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
