Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a snap-fit ​​connection device. Background Technology

[0002] Common connection methods used in automobile assembly include bolted connections (i.e., threaded fastening with bolts and nuts), adhesive bonding, riveting, and clip-on fastening. Among these, clip-on fastening is frequently used for securing parts such as interior trim components.

[0003] When using clips to secure parts, if the parts need to be disassembled for repair, it is often necessary to use force to forcibly remove parts such as interior panels, making disassembly and replacement inconvenient, and may even damage the parts and clips, making the clips unusable and limiting the convenience and economy of using automotive parts.

[0004] Therefore, this application provides a new snap-fit ​​connection device to address the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a snap-fit ​​connection device to at least alleviate the technical problems of troublesome disassembly and assembly of parts and inconvenient replacement and maintenance in the prior art.

[0006] To achieve the above objectives, the present invention provides a snap-fit ​​connection device for fixing a component to be installed to a plate, the snap-fit ​​connection device comprising: A clamping mechanism, wherein the clamping mechanism is used to clamp the part to be installed onto the surface of the plate; and A locking mechanism is provided for locking the clamping mechanism to the plate, and the locking mechanism includes a locked state that locks the clamping mechanism to the plate and an unlocked state that unlocks the clamping mechanism from the plate.

[0007] Furthermore, the clamping mechanism includes a clamping plate and a connecting shaft connected to the clamping plate. The connecting shaft can pass through the component to be installed and the plate in sequence, so that the component to be installed is clamped between the clamping plate and the plate. The locking mechanism is connected to the connecting shaft.

[0008] Furthermore, the locking mechanism includes a pressing shaft connected to the clamping plate and an elastic claw connected to the pressing shaft. After the connecting shaft passes through the part to be installed and the plate, the elastic claw is located on the side of the plate away from the clamping plate. The pressing shaft can move towards or away from the clamping plate. When the pressing shaft moves towards the clamping plate, the elastic claw can contact the plate and lock itself onto the plate.

[0009] Furthermore, multiple elastic claws are provided, and the multiple elastic claws are spaced apart circumferentially along the pressing axis.

[0010] Furthermore, the locking mechanism also includes a locking nut screwed onto the connecting shaft. After the connecting shaft passes through the part to be installed and the plate, the locking nut is located on the side of the plate away from the clamping plate, and the elastic claw is located between the plate and the locking nut. When the pressing axis moves towards the clamping plate, the elastic claw can contact the plate. At this time, the locking nut is rotated towards the elastic claw to contact the elastic claw and lock the elastic claw to the plate.

[0011] Furthermore, the connecting shaft is a hollow shaft with an inner cavity, the pressing shaft is inserted into the inner cavity and connected to the clamping plate; The peripheral wall of the connecting shaft is provided with a guide groove that communicates with the inner cavity. The elastic claw extends beyond the connecting shaft through the guide groove, and when the pressing axis moves toward or away from the clamping plate, the elastic claw can move along the guide groove.

[0012] Furthermore, an elastic element is connected between the pressing shaft and the clamping plate. When the pressing shaft moves toward the clamping plate, the elastic element is gradually compressed.

[0013] Furthermore, the elastic element is a spring or a sheet spring.

[0014] Furthermore, the outer peripheral wall of the pressing shaft is provided with a convex shaft, and the connecting shaft is provided with a locking hole on the side near the inner cavity; The pressing shaft is disposed in the inner cavity and is clearance-fitted with the connecting shaft; When the pressing axis moves towards the clamping plate until the elastic claw contacts the plate, the pressing axis moves radially within the inner cavity, allowing the convex shaft to be inserted into the locking hole.

[0015] Furthermore, the locking nut has a groove on the side near the elastic claw. When the pressing shaft can move away from the clamping plate, the elastic claw can elastically deform to retract into the groove.

[0016] By adopting the above technical solution, the snap-fit ​​connection device of the present invention has at least the following beneficial effects: When using the snap-fit ​​connection device of this embodiment, the component to be installed is first placed on the plate, and then the component to be installed is clamped to the surface of the plate by the clamping mechanism. Then, the clamping mechanism is locked to the plate by the locking mechanism, so that the locking mechanism is in the locked state, thereby fixing the component to be installed to the plate. When it is necessary to disassemble it, the locking mechanism is first unlocked, at which time the clamping mechanism is unlocked from the plate, and then the clamping mechanism is disassembled, so that the component to be installed can be taken out from the plate, which is convenient for replacing new parts or repairing the component to be installed.

[0017] In summary, using the snap-fit ​​connection device of this embodiment makes the disassembly and installation of parts convenient and will not cause damage to the parts. Furthermore, the snap-fit ​​connection device can be reused, alleviating the technical problems of troublesome disassembly and assembly and inconvenient replacement and maintenance of parts in the prior art.

[0024] Example Please see Figure 1 and Figure 2 This embodiment provides a snap-fit ​​connection device for fixing the part to be installed 1 to the plate 2. The snap-fit ​​connection device includes a clamping mechanism 3 and a locking mechanism 4. The clamping mechanism 3 is used to clamp the part to be installed 1 to the surface of the plate 2. The locking mechanism 4 is used to lock the clamping mechanism 3 to the plate 2. The locking mechanism 4 includes a locked state that locks the clamping mechanism 3 to the plate 2 and an unlocked state that unlocks the clamping mechanism 3 from the plate 2.

[0025] When using the snap-fit ​​connection device of this embodiment, the component to be installed 1 is first placed on the plate 2, and then the component to be installed 1 is clamped to the surface of the plate 2 by the clamping mechanism 3. Then, the clamping mechanism 3 is locked to the plate 2 by the locking mechanism 4, so that the locking mechanism 4 is in the locked state, thereby fixing the component to be installed 1 to the plate 2. When it is necessary to disassemble it, the locking mechanism 4 is first unlocked, at which time the clamping mechanism 3 is unlocked from the plate 2, and then the clamping mechanism 3 is disassembled, so that the component to be installed 1 can be taken out from the plate 2, which is convenient for replacing new parts or repairing the component to be installed 1.

[0026] In summary, using the snap-fit ​​connection device of this embodiment makes the disassembly and installation of parts convenient and will not cause damage to the parts. Furthermore, the snap-fit ​​connection device can be reused, alleviating the technical problems of troublesome disassembly and assembly and inconvenient replacement and maintenance of parts in the prior art.

[0027] Preferably, please refer to Figure 3 In this embodiment, the clamping mechanism 3 includes a clamping plate 31 and a connecting shaft 32 connected to the clamping plate 31. The connecting shaft 32 can pass through the component to be installed 1 and the plate 2 in sequence, so that the component to be installed 1 is clamped between the clamping plate 31 and the plate 2. The locking mechanism 4 is connected to the connecting shaft 32.

[0028] It should be noted that the plate 2 can be sheet metal or plastic, and can be flat, curved, etc. Correspondingly, the clamping plate 31 can be flat, curved, etc. The clamping mechanism 3 clamps the part to be installed 1 between the clamping plate 31 and the plate 2. Therefore, the shape of the clamping plate 31 matches the side of the part to be installed 1 away from the plate 2.

[0029] Preferably, please refer to Figure 3 and combined Figure 1 In this embodiment, the locking mechanism 4 includes a pressing shaft 41 connected to the clamping plate 31 and an elastic claw 42 connected to the pressing shaft 41. After the connecting shaft 32 passes through the part to be installed 1 and the plate 2, the elastic claw 42 is located on the side of the plate 2 away from the clamping plate 31. The pressing shaft 41 can move towards or away from the clamping plate 31. When the pressing shaft 41 moves towards the clamping plate 31, the elastic claw 42 can contact the plate 2 and lock onto the plate 2.

[0030] With this setup, when using the snap-fit ​​connection device of this embodiment, the component to be installed 1 is first placed on the plate 2, and then the connecting shaft 32 passes through the component to be installed 1 and the plate 2 in sequence, so that the component to be installed 1 is clamped between the clamping plate 31 and the plate 2. Then, the pressing shaft 41 is moved towards the clamping plate 31, so that the elastic claw 42 moves accordingly until the elastic claw 42 contacts the plate 2 and locks onto the plate 2. At this time, the locking mechanism 4 is in a locked state, thus locking the component to be installed 1 between the clamping plate 31 and the plate 2.

[0031] When it is necessary to disassemble the part to be installed 1, first unlock the elastic claw 42 from the plate 2, then move the pressing shaft 41 away from the clamping plate 31, so that the elastic claw 42 moves accordingly until the elastic claw 42 disengages from the plate 2, and the connecting shaft 32 can move away from the plate 2, so that the part to be installed 1 loses the clamping force of the clamping plate 31 and can be disassembled and removed, which is convenient for replacing new parts or repairing the part to be installed 1.

[0032] Preferably, please refer to Figure 1In this embodiment, multiple elastic claws 42 are provided, and the multiple elastic claws 42 are spaced apart along the circumferential direction of the pressing shaft 41.

[0033] For example, the elastic claws 42 can be configured to have two, three, four, or five, etc.

[0034] Preferably, multiple elastic claws 42 are evenly arranged along the circumference of the pressing shaft 41. This arrangement makes the locking of the elastic claws 42 on the part to be installed more stable and reliable, and prevents the part to be installed from moving between the clamping plate 31 and the plate 2.

[0035] Preferably, please refer to Figure 1 and Figure 2 In this embodiment, the locking mechanism 4 further includes a locking nut 43 screwed onto the connecting shaft 32. After the connecting shaft 32 passes through the part to be installed 1 and the plate 2, the locking nut 43 is located on the side of the plate 2 away from the clamping plate 31, and the elastic claw 42 is located between the plate 2 and the locking nut 43. When the pressing shaft 41 moves toward the clamping plate 31, the elastic claw 42 can contact the plate 2. At this time, the locking nut 43 is rotated toward the elastic claw 42, so that it can contact the elastic claw 42 and lock the elastic claw 42 onto the plate 2.

[0036] With this setup, when using the snap-fit ​​connection device of this embodiment, the component to be installed 1 is first placed on the plate 2, and then the connecting shaft 32 passes through the component to be installed 1 and the plate 2 in sequence, so that the component to be installed 1 is clamped between the clamping plate 31 and the plate 2. Then, the pressing shaft 41 is moved towards the clamping plate 31, so that the elastic claw 42 moves accordingly until the elastic claw 42 contacts the plate 2. Then, the locking nut 43 is rotated towards the elastic claw 42, so that the locking nut 43 contacts the elastic claw 42, and the elastic claw 42 is locked to the plate 2 by the locking nut 43. At this time, the locking mechanism 4 is in the locked state, thus realizing the locking of the component to be installed 1 between the clamping plate 31 and the plate 2.

[0037] When it is necessary to disassemble the part to be installed 1, first rotate the locking nut 43 away from the elastic claw 42 to disengage the locking nut 43 from the elastic claw 42. At this time, the locking mechanism 4 is in the unlocked state, and the elastic claw 42 loses the support of the locking nut 43. Then move the pressing shaft 41 away from the clamping plate 31, so that the elastic claw 42 moves accordingly until the elastic claw 42 disengages from the plate 2. The connecting shaft 32 can then move away from the plate 2, so that the part to be installed 1 loses the clamping force of the clamping plate 31 and can be disassembled and removed for easy replacement of new parts or maintenance of the part to be installed 1.

[0038] Preferably, please refer to Figure 3In this embodiment, the connecting shaft 32 is a hollow shaft with an inner cavity. The pressing shaft 41 is inserted into the inner cavity and connected to the clamping plate 31. The peripheral wall of the connecting shaft 32 is provided with a guide groove 33 that communicates with the inner cavity. The elastic claw 42 extends beyond the connecting shaft 32 through the guide groove 33. When the pressing shaft 41 moves toward or away from the clamping plate 31, the elastic claw 42 can move along the guide groove 33.

[0039] This design reduces the size of the snap-fit ​​connection device, making it more compact and easier to use. Furthermore, the guide groove 33 allows the elastic claw 42 to extend beyond the connecting shaft 32 for contact with the plate 2, and also guides the movement of the pressing shaft 41 towards or away from the clamping plate 31, making the movement of the pressing shaft 41 more stable and reducing the problem of the pressing shaft 41 rotating relative to the connecting shaft 32 during movement.

[0040] Preferably, please refer to Figure 1 In this embodiment, an elastic element 44 is connected between the pressing shaft 41 and the clamping plate 31. When the pressing shaft 41 moves toward the clamping plate 31, the elastic element 44 is gradually compressed.

[0041] With this setup, after the component to be installed 1 is installed on the plate 2, the elastic element 44 is in a compressed state. When the component to be installed 1 is removed, the locking nut 43 rotates away from the elastic claw 42, causing the locking nut 43 to disengage from the elastic claw 42. At this time, the elastic claw 42 loses the support of the locking nut 43. Under the action of the pre-tightening force of the elastic element 44, it can drive the pressing shaft 41 to move away from the clamping plate 31, realizing automatic unlocking and further facilitating the disassembly of the parts.

[0042] Optionally, the elastic element 44 is a spring or a sheet spring.

[0043] Preferably, please refer to Figure 3 In this embodiment, a convex shaft 45 is provided on the outer peripheral wall of the pressing shaft 41, and a locking hole is provided on the side of the connecting shaft 32 near the inner cavity; the pressing shaft 41 is disposed in the inner cavity and is clearance-fitted with the connecting shaft 32; when the pressing shaft 41 moves towards the clamping plate 31 until the elastic claw 42 contacts the plate 2, the pressing shaft 41 moves radially within the inner cavity, allowing the convex shaft 45 to be inserted into the locking hole.

[0044] With this setup, when fixing the part to be installed 1, pressing the pressing shaft 41 moves it closer to the clamping plate 31, causing the elastic claw 42 to contact the plate 2. Then, the pressing shaft 41 moves radially within the inner cavity so that the convex shaft 45 is inserted into the locking hole, achieving initial locking of the pressing shaft 41. At this point, the operator's hand can be removed from the pressing shaft 41 to operate the locking nut 43, causing the locking nut 43 to rotate closer to the elastic claw 42.

[0045] When it is necessary to disassemble the part to be installed 1, first rotate the locking nut 43 away from the elastic claw 42 to disengage the locking nut 43 from the elastic claw 42. Then move the pressing shaft 41 radially within the inner cavity so that the convex shaft 45 is pulled out of the locking hole. The pressing shaft 41 loses its constraint and, under the pre-tightening force of the elastic element 44, the pressing shaft 41 automatically moves away from the clamping plate 31, thereby disengaging the elastic claw 42 from the plate 2.

[0046] Preferably, please refer to Figure 2 and combined Figure 4 In this embodiment, the locking nut 43 is provided with a groove 431 on the side near the elastic claw 42. When the pressing shaft 41 can move away from the clamping plate 31, the elastic claw 42 can elastically deform to retract into the groove 431.

[0047] With this configuration, when disassembling the part to be installed 1, the pressing shaft 41 moves away from the clamping plate 31 until the elastic claw 42 contacts the locking nut 43. The pressing shaft 41 continues to move away from the clamping plate 31, causing the elastic claw 42 to undergo elastic deformation under the limiting action of the locking nut 43 and retract into the groove 431. As a result, the radial dimension of the snap-fit ​​connection device is reduced, making it easier to pull the snap-fit ​​connection device out of the hole on the plate 2 and the part to be installed 1.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
