Description

Technical Field

[0001] This utility model belongs to the technical field of tailgate lock body, specifically relating to a riveting structure for a tailgate lock body. Background Technology

[0002] In the field of motorcycle parts and manufacturing, the lock body of the motorcycle tail box is a fastener whose reliability directly determines the safety and service life of the tail box. The straight pull stud (straight pull riveting) of the traditional tail box lock body is widely used in the connection of motorcycle tail box and other components due to its simple structure, convenient installation and cost advantages, especially in structures such as tail box lock bodies that need to be opened and closed repeatedly.

[0003] The existing straight pull studs are based on a single mechanical model of "linear tension-radial expansion". The core rod is pulled to expand the sleeve and form a mechanical engagement with the pre-made hole wall. This structure leads to two key limitations: First, the direction of force is extremely dependent on axial load. When the motorcycle encounters road bumps, impacts from rapid acceleration and deceleration, or lateral forces when the tail box is opened or closed, micro gaps are prone to appear at the connection interface. After long-term vibration cycles, the torque decays significantly, exceeding the industry safety threshold. Second, the plastic deformation of the material is concentrated in the local area of ​​the sleeve. The resulting "point contact" interlocking structure has insufficient shear strength. In the alloy material connection commonly used in motorcycle lightweighting, the probability of shear force failure is significantly increased, causing the relative position of the lock body and the tail box to shift, which manifests as lock cylinder shaking, jamming, or even functional failure. Utility Model Content

[0004] The purpose of this utility model is to provide a riveting structure for a tailgate lock body to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A riveting structure for a tailgate lock body, comprising:

[0006] Upper locking body, which is installed on the tail box, is used to lock the tail box body and the lid of the tail box; lower locking body, which is installed on the box body, is used to securely lock the box body to the motorcycle tail rack.

[0007] The locking body includes a locking face cover, a locking face cover buckle, and a locking bottom cover. The locking face cover, the locking face cover buckle, and the locking bottom cover are connected by two sets of first rivet pins, so that the locking face cover buckle can rotate relative to the locking face cover around the first rivet pin, and the locking bottom cover can rotate relative to the locking face cover through another set of first rivet pins, thereby meeting the activity requirements of the lock body during locking and unlocking.

[0008] The lower lock body includes a lower lock face cover, a lower lock cover buckle, and a lower lock bottom cover. The lower lock face cover, the lower lock cover buckle, and the lower lock bottom cover are also riveted together by two sets of first rivet pins, so that the lower lock cover buckle can rotate relative to the lower lock face cover around the first rivet pin, and the lower lock bottom cover can rotate relative to the lower lock face cover by another set of first rivet pins, thereby meeting the movement requirements of the lock body during locking and unlocking.

[0009] Preferably, a movable switch is slidably connected inside both the upper and lower locking bottom covers. Guide rods are connected to both ends of the movable switch. Guide grooves are provided on both sides of the upper and lower locking bottom covers, and the guide rods are slidably connected in the guide grooves. The movable switch is provided inside the upper and lower locking bottom covers. Through the sliding cooperation between the guide rods and the guide grooves, a stable sliding trajectory is provided for the movable switch, ensuring that it slides smoothly without deviation.

[0010] Preferably, both the upper and lower locking covers have slots on both sides of their bottom, and the guide rod is inserted into the slots. Both the upper and lower locking covers have lock heads with limit plates connected to their bottoms. The position of the movable switch is fixed by the engagement of the slots and the guide rod. The lock heads and limit plates in the upper and lower locking covers provide a structural basis for restricting the movement of the movable switch.

[0011] Preferably, one end of the movable switch is connected to a push plate, and the other end is connected to a short rod. Both ends of the upper and lower locking covers are provided with slots. The push plate and the short rod slide through the slots respectively. A spring is fitted on the short rod, and both ends of the spring are connected to the movable switch and the upper or lower locking cover respectively. The movable switch is operated and moved by sliding along the slots with the push plate and the short rod. The movable switch is connected to the cover by the spring, so that the movable switch can automatically reset after operation.

[0012] Preferably, both the upper and lower locking covers have a fixing buckle on one side, and a second rivet pin is riveted to the fixing buckle. Both the upper and lower locking cover fasteners have an arc-shaped groove at their bottom, and the second rivet pin is inserted into the arc-shaped groove. The riveting connection between the fixing buckle and the second rivet pin, combined with the engagement of the second rivet pin with the arc-shaped groove of the fastener, restricts the rotation trajectory of the fastener and prevents misalignment of the fastener to ensure accurate locking.

[0013] Preferably, the movable switch is internally connected to a limiting post, and the limiting piece is used to abut against the limiting post to restrict the movement of the movable switch. The movement of the movable switch is restricted by the abutting cooperation between the limiting post inside the movable switch and the limiting piece at the bottom of the lock head, so as to prevent the movable switch from being accidentally activated due to vibration while the motorcycle is running.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The riveting process of this structure uses "rotation + axial pressure" to make the riveting pin material uniformly plastically deformed to form "surface contact" locking, which can withstand axial, lateral and shear forces at the same time. The torque attenuation rate is significantly reduced compared with traditional straight pull nails, and the lower lock body can maintain a stable connection between the box and the tail frame for a long time, avoiding the tail box shaking during driving.

[0016] (2) The riveting connection of the two sets of first rivet pins ensures the smooth rotation of the buckle and bottom cover relative to the top cover, and avoids shaking caused by excessive gap. The cooperation between the second rivet pin and the arc groove further restricts the rotation trajectory, prevents the buckle from being misaligned, and ensures that each locking is accurate.

[0017] (3) The contact between the limit plate and the limit post can lock the position of the movable switch to prevent accidental locking due to vibration during motorcycle operation (avoiding the tail box from opening accidentally or detaching from the tail frame). The design of the guide rod being inserted into the slot avoids the movable switch from shifting and causing loose locking, further ensuring driving safety. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] This utility model provides, for example Figure 1-6 The tailgate lock body shown has a riveting structure comprising:

[0028] Locking body 1 is installed on the tailgate or the corresponding position of the tailgate. Its core function is to realize the controllable locking / unlocking action of the tailgate body and the tailgate. Through the linkage of its own components, it ensures the sealing when the tailgate is closed and the smoothness when it is opened, and avoids relative displacement between the tailgate body and the tailgate during driving.

[0029] Lower locking body 2 is installed at the bottom of the tail box and is used to form a rigid connection between the tail box and the motorcycle tail frame. It can resist the longitudinal and lateral impact forces generated by the bumps and rapid acceleration / deceleration during the motorcycle's operation, and prevent the tail box from separating from the tail frame or from large shaking.

[0030] The locking body 1 includes a locking face cover 3, a locking cover buckle 4, and a locking bottom cover 5. The locking face cover 3 is an external protective and structural support component of the locking body 1, which can protect the internal components from external dust, rain, and impact damage. The locking cover buckle 4 is a core locking transmission component, which is used to adapt to the locking structure of the tail box body to realize the connection between the locking body 1 and the box body. The locking bottom cover 5 is a mounting carrier for internal moving parts, providing a stable installation and movement space for components such as the movable switch 10.

[0031] The upper locking cover 3, the upper locking cover buckle 4, and the upper locking bottom cover 5 are connected by two sets of first rivet pins 6 using a riveting process. The riveting process uses the combined action of "rotating rivet head + axial pressure" to make the metal at the end of the first rivet pin 6 undergo uniform plastic deformation, forming a "surface contact" locking structure that is tightly fitted to the surface of the component. Compared with the "point contact" engagement of traditional straight pull pins, it can simultaneously withstand axial load and lateral shear force, significantly reducing the torque attenuation rate after long-term vibration and avoiding shaking caused by micro-gaps between lock body components.

[0032] The two sets of first rivet pins 6 have clearly defined functions: one set is used to realize the rotation of the upper cover latch 4 relative to the upper cover 3 around the axis, which meets the matching action of the latch and the lid locking structure when locked, and ensures that the latch can accurately engage or disengage from the locking position; the other set is used to realize the rotation of the upper bottom cover 5 relative to the upper cover 3 around the axis, which adapts to the position adjustment requirements of the bottom cover and the box body during the opening and closing of the tail box, while avoiding the looseness of the parts caused by excessive clearance, and ensuring the stability of the lock body during the locking and unlocking process;

[0033] The lower lock body 2 includes a lower lock face cover 7, a lower lock cover buckle 8, and a lower lock bottom cover 9. The functions of each component are the same as the corresponding components of the upper lock body 1: the lower lock face cover 7 is a structural support and protective component of the lower lock body 2, the lower lock cover buckle 8 is used to adapt to the locking structure of the motorcycle tail rack, and the lower lock bottom cover 9 is the mounting carrier for the internal moving parts of the lower lock body 2.

[0034] The lower lock cover 7, lower lock cover buckle 8, and lower lock bottom cover 9 are also connected by two sets of first rivet pins 6. The connection principle is the same as that of the upper lock body 1. This ensures that the lower lock cover buckle 8 can rotate flexibly relative to the lower lock cover 7 around the first rivet pin 6, and the lower lock bottom cover 9 can rotate relative to the lower lock cover 7 through another set of first rivet pins 6. It also maintains the connection strength of each component of the lower lock body 2, meets the activity requirements of the tail box and tail frame during locking and unlocking, and avoids relative displacement between the tail box and tail frame during driving.

[0035] Both the upper locking bottom cover 5 and the lower locking bottom cover 9 are slidably connected to a movable switch component 10. The movable switch component 10 is the core actuator for locking / unlocking the lock body. It drives the associated structure to switch the locking state through lateral sliding, preventing accidental operation in non-operational states. The movable switch component 10 is symmetrically connected to guide rods 11 at both ends. The guide rods 11 and the movable switch component 10 form an integrated structure and can move laterally synchronously with the movable switch component 10. Both sides of the upper locking bottom cover 5 and the lower locking bottom cover 9 are provided with guide grooves 12 that are adapted to the guide rods 11, and the guides... The rod 11 is slidably connected in the guide groove 12. The guide rod 11 and the guide groove 12 form a sliding guide pair, which limits the movement trajectory of the movable switch 10 to a straight line, so as to avoid the movable switch 10 from being unable to lock or getting stuck due to the offset during lateral movement. The groove wall of the guide groove 12 and the guide rod 11 maintain a preset gap, which not only ensures that the guide rod 11 slides smoothly, but also limits the lateral movement of the guide rod 11 by the groove wall, resists the impact of motorcycle vibration on the movable switch 10, maintains its positional stability, and prevents the guide rod 11 from coming out of the guide groove 12.

[0036] Both the upper locking cover 3 and the lower locking cover 7 have slots 13 on both sides of their bottom that are adapted to the guide rod 11. When the movable switch 10 slides to the locked position, the guide rod 11 is engaged in the slot 13. The slot 13 provides axial limit for the guide rod 11, forming a mechanical stop to prevent the movable switch 10 from sliding backward due to vibration or accidental contact by external force, thus ensuring the reliability of the lock body's locked state.

[0037] Both the upper locking cover 3 and the lower locking cover 7 are equipped with lock heads 14. The lock heads 14 provide an interface for external operation (such as key turning). The rotation of the lock heads 14 drives the associated components to lock / unlock the lock body. Its structural strength meets the requirements of long-term operation and avoids damage caused by repeated key turning. The bottom of the lock head 14 is fixedly connected to a limiting piece 15. The limiting piece 15 rotates synchronously with the lock head 14 and serves as a locking component for the movable switch 10. By cooperating with the limiting structure of the movable switch 10, it restricts the movement of the movable switch 10 and ensures that the movable switch 10 cannot move when not in operation.

[0038] One end of the movable switch 10 is fixedly connected to a push plate 16. The push plate 16 serves as the force-applying component for the user to operate the movable switch 10. The portion of the push plate 16 extending beyond the upper locking cover 3 or the lower locking cover 7 is provided with anti-slip texture to increase the friction between the hand and the push plate 16, making it easier for the user to slide the movable switch 10 by pushing the push plate 16, thus improving the ease of operation. The other end of the movable switch 10 is fixedly connected to a short rod 17. The short rod 17 and the push plate 16 are located at opposite ends of the movable switch 10, and their axes are aligned with the sliding direction of the movable switch 10, ensuring that the movable switch 10 is subjected to balanced force and preventing tilting during sliding. Both ends of the upper locking cover 3 and the lower locking cover 7 are provided with slots 18 that are adapted to the push plate 16 and the short rod 17. The push plate 16 and the short rod 17 slide through the slots 18, which provide space for the movement of the push plate 16 and the short rod 17 while limiting their range of motion, preventing damage to the associated structure due to excessive movement of the short rod 17 or the push plate 16.

[0039] A spring 19 is fitted on the short rod 17, and the two ends of the spring 19 are fixedly connected to the movable switch 10 and the inner wall of the upper locking cover 3 or the lower locking cover 7, respectively. The spring 19 provides the reset power for the movable switch 10. When the user releases the push plate 16, the spring 19 returns from the compressed state to the natural state, and pushes the movable switch 10 to automatically reset to the locked position through the short rod 17, without the need for manual adjustment.

[0040] Both the upper lock cover 3 and the lower lock cover 7 are provided with a fixing buckle 20 on one side. The fixing buckle 20 is used to connect the lock body to the tail box cover (upper lock body 1) or the motorcycle tail frame (lower lock body 2). Its structural strength and installation position have been designed through stress analysis to ensure that the fixing buckle 20 can withstand the weight of the tail box and the load generated by driving vibration, and to avoid the locking body from failing due to the breakage of the fixing buckle 20.

[0041] The fixing buckle 20 is connected to a second rivet pin 21 by a riveting process. The riveting process causes the metal at the end of the second rivet pin 21 to undergo uniform plastic deformation, forming a stable integrated structure with the fixing buckle 20. Compared with traditional bolt connections, no threaded fit is required, avoiding the second rivet pin 21 from falling off due to loose threads. At the same time, after the end of the second rivet pin 21 is deformed, it fits against the surface of the fixing buckle 20, improving the connection strength and resisting lateral shear force. The bottom of the upper locking cover buckle 4 and the lower locking cover buckle 8 are provided with an arc-shaped groove 22 that matches the second rivet pin 21, and the second rivet pin 21 is inserted into the arc-shaped groove 22. The arc-shaped groove 22 and the second rivet pin 21 form a sliding limiting pair. When the buckle (upper locking cover buckle 4 / lower locking cover buckle 8) rotates around the first rivet pin 6, the second rivet pin 21 slides along the arc-shaped groove 22, limiting the rotation trajectory of the buckle and preventing the buckle from misaligning due to excessive rotation angle or offset.

[0042] The radius of curvature of the arc groove 22 is matched with the rotation radius of the fastener, ensuring that the second rivet pin 21 slides smoothly. At the same time, the two ends of the arc groove 22 are provided with limiting protrusions to prevent the second rivet pin 21 from coming out of the arc groove 22, ensuring the structural stability of the fastener during rotation and ensuring that each locking is accurate.

[0043] The movable switch 10 is fixedly connected to a limiting post 23. The axis of the limiting post 23 is perpendicular to the sliding direction of the movable switch 10. The limiting piece 15 is used to abut against the limiting post 23 to restrict the movement of the movable switch 10. The contact surface between the limiting piece 15 and the limiting post 23 is a plane or an arc-shaped surface to ensure that the force is uniform when the two are in contact, and to avoid local stress concentration that could cause damage to the component.

[0044] When the lock head 14 drives the limiting plate 15 to the locked position, the limiting plate 15 and the limiting post 23 are tightly abutted together. The blocking force of the limiting plate 15 on the limiting post 23 restricts the lateral movement of the movable switch 10, preventing the movable switch 10 from being accidentally activated due to vibration during motorcycle operation. When the lock head 14 drives the limiting plate 15 to the unlocked position, the limiting plate 15 and the limiting post 23 are disengaged, releasing the restriction on the movable switch 10. The movable switch 10 can slide freely, realizing the unlocking of the lock body.

[0045] The riveting structure of the tailgate lock body has three core components: upper lock body 1, upper lock face cover 3, upper lock cover buckle 4, and upper lock bottom cover 5. The lower lock body 2 has three corresponding components: lower lock face cover 7, lower lock cover buckle 8, and lower lock bottom cover 9. Two sets of first rivet pins 6 pass through the pre-made holes of each component of the upper lock body 1 and the lower lock body 2. The pre-made holes are kept coaxial to allow the first rivet pins 6 to pass through smoothly. The riveting head of the riveting equipment is aligned with the end of the first rivet pin 6 and rotates at high speed while applying axial pressure. This causes the metal material at the end of the rivet pin to undergo uniform plastic deformation under the combined force, forming a protruding structure similar to a "mushroom head". This structure fits tightly against the surface of the component, forming a "surface contact" locking structure. In contrast, traditional straight pull studs only expand the stud body through linear stretching, and the engagement with the component is a "point contact" engagement, which is far less stable than the riveting structure.

[0046] During the riveting operation, while controlling the degree of deformation of the first rivet pin 6, it is also necessary to ensure that the deformed rivet pin firmly locks each component to prevent the parts from loosening, and to reserve rotation space for specific components. Taking the lock body 1 as an example, it is necessary to ensure that the upper lock cover buckle 4 can rotate flexibly relative to the upper lock face cover 3 around the first rivet pin 6, and at the same time, the upper lock bottom cover 5 can also rotate relative to the upper lock face cover 3 through another set of first rivet pins 6 (the linkage relationship of each component of the lower lock body 2 is completely consistent), to meet the movement requirements of the components when the lock body is opened and closed, and to prevent the components from jamming due to excessive riveting and being unable to rotate normally.

[0047] Based on the linkage relationship formed by the riveting connection, the lock body realizes the complete process of locking and unlocking through the cooperation of the movable switch 10 and the elastic structure. The components work together in a specific sequence, as follows:

[0048] The upper lock cover 3 is connected to the trunk body, and the fixing buckle 20 is connected to the trunk lid. When the trunk needs to be unlocked, the key is inserted into the lock cylinder 14 and turned. This causes the limiting plate 15 at the bottom of the lock cylinder 14 to rotate, disengaging from the limiting post 23. The locked state of the movable switch 10 is released. Normally, when the lock cylinder 14 is locked, it will jam the limiting post 23, restricting the movement of the movable switch 10. After the lock is released, when the limiting post 23 on the inner side of the movable switch 10 is disengaged from the limiting plate 15 at the bottom of the lock cylinder 14, a finger pushes the push plate 16 at one end of the movable switch 10. The push plate 16 slides along the preset slot 18 of the upper lock cover 3 / lower lock cover 7. Since the push plate 16 and the movable switch 10 are an integrated structure, it will directly drive the movable switch 10 to move horizontally synchronously. Both ends of the movable switch 10 are provided with guide rods 11, and the upper lock bottom cover 5 / lower lock bottom cover 9 are provided with guide grooves 12 at corresponding positions. The rod 11 is embedded in the guide groove 12 and slides along the guide groove 12 as the movable switch 10 moves, preventing the movable switch 10 from deviating and ensuring that it always moves smoothly along the preset trajectory. The other end of the movable switch 10 is provided with a short rod 17, which is connected to one end of the spring 19. The other end of the spring 19 is fixed to the spring 19 seat on the inside of the cover. When the movable switch 10 moves, the short rod 17 will compress the spring 19, allowing the spring 19 to store elastic potential energy. Since the pusher 16 at one end of the movable switch 10 can be pushed by a finger, the guide rod 11 can be driven to slide out of the slot 13, causing the locking bottom cover 5 and the locking front cover 3 to disengage. At this time, as the locking state of the movable switch 10 is released, the upper lock cover latch 4 / lower lock cover latch 8 can rotate freely around the first rivet pin 6, causing the second rivet pin 21, which is inserted into the arc groove 22, to slide out along the arc groove 22 and disengage, finally completing the unlocking of the lock body and allowing the tail box to be opened smoothly.

[0049] Locking process:

[0050] When the external force applied to the push plate 16 is released, the compressed spring 19 releases its elastic potential energy, pushing the short rod 17 to move in the opposite direction, thereby causing the movable switch 10 to reset. The guide rods 11 at both ends of the movable switch 10 slide back to the initial position of the guide groove 12, and the guide rods 11 will be engaged in the slots 13 on both sides of the upper lock cover 3. After the movable switch 10 is reset, the key is inserted into the lock cylinder 14 and turned. The limiting plate 15 at the bottom of the lock cylinder 14 and the limiting post 23 in the movable switch 10 will re-engage. Upon contact, the limiting piece 15 again engages with the limiting post 23, locking the position of the movable switch 10 to prevent it from moving arbitrarily. At this time, pushing the tailgate lid will cause the locking cover latch 4 to rotate in the opposite direction. The arc groove 22 on the locking cover latch 4 slides along the second rivet pin 21 and engages with the second rivet pin 21 until the locking cover latch 4 returns to its initial position and fully engages with the locking structure of the tailgate body, thus achieving a stable lock between the lock body and the tailgate body and the lid, ensuring that the tailgate will not open by itself during use.

[0051] The lower lock body 2 includes a lower lock face cover 7, a lower lock cover buckle 8, a lower lock bottom cover 9, and a fixing buckle 20. The lower lock face cover 7 is connected to the bottom of the tail box, while the fixing buckle 20 is connected to the motorcycle tail rack. When it is necessary to unlock and lock the tail box and the motorcycle tail rack, the above unlocking steps of the tail box body and the cover can be repeated.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
