The worker quickly switches the assembly tool 100 according to the type of vehicle components, which reduces the waste of operation actions, improves the convenience of operation, and improves the assembly efficiency; the following is an explanation through specific implementation methods:

[0048] Please also read Figure 3The switching assembly tool 100 of this embodiment includes: a first assembly part 1 and a second assembly part 2; the first assembly part 1 includes a first assembly body 11 and a first assembly part 12 provided at the end of the first assembly body 11 and used to assemble the first component 200; the second assembly part 2 includes a second assembly body 21 and a second assembly part 22 provided at the end of the second assembly body 21 and used to assemble the second component 300, the second assembly body 21 is provided with a telescopic through hole 23 along its own axial direction X, the first assembly body 11 is penetrated in the telescopic through hole 23 and can move along the axial direction X of the second assembly body 21, and the first assembly part 12 can extend or retract relative to the second assembly part 22 as the first assembly body 11 moves; the first assembly part 12 is used to assemble and connect with the first component 200 when the first assembly part 12 is extended, and the second assembly part 22 is used to assemble and connect with the second component 300 when the first assembly part 12 is retracted.

[0049] Here, it can be understood that the first assembly part 1 refers to a component used to assemble the first component 200; the first assembly part 1 includes a first assembly body 11 and a first assembly portion 12, the first assembly body 11 refers to a body used for the first assembly part 1, and the first assembly body 11 is used to set the first assembly portion 12; the first assembly portion 12 refers to a component used to connect with the first component 200, wherein the first assembly portion 12 can exert a force on the first component 200 under the drive of an external force, so that the first component 200 is assembled;

[0050] The second assembly part 2 refers to a component used to assemble the second component 300; the second assembly part 2 includes a second assembly body 21 and a second assembly part 22, the second assembly body 21 refers to a body used for the second assembly part 2, and the second assembly body 21 is used to set the second assembly part 22; the second assembly part 22 refers to a component used to connect with the second component 300, wherein the second assembly part 22 can exert a force on the second component 300 under the drive of an external force, so that the second component 300 is assembled;

[0051] Among them, the second assembly body 21 is provided with a telescopic through hole 23, and the telescopic through hole 23 extends along the axial direction X of the second assembly body 21, that is, the depth direction of the telescopic through hole 23 is parallel to the axial direction X of the second assembly body 21; the first assembly body 11 is penetrated by the telescopic through hole 23, and the first assembly body 11 can move along the axial direction X of the second assembly body 21 in the telescopic through hole 23, and the first assembly part 12 can move with the movement of the first assembly body 11, and the first assembly part 12 can extend or retract relative to the second assembly part 22. When the first assembly part 12 extends out of the second assembly part 22, the first assembly part 12 is used to connect with the first component 200 to realize the assembly operation of the first component 200; when the second assembly part 22 retracts into the second assembly part 22, the second assembly part 22 is used to connect with the second component 300 to realize the assembly operation of the second component 300.

[0052] Please also read Figure 4 and Figure 5 The working principle of the switching assembly tool 100 provided in this embodiment is as follows:

[0053] The switching assembly tool 100 of the present embodiment can be used to assemble two types of vehicle components, including but not limited to studs or nuts; the present embodiment is explained by adjusting the studs and tightening the nuts in the vehicle assembly operation. In actual application scenarios, the switching assembly tool 100 of the present embodiment can assemble other suitable vehicle components. The nuts of the present embodiment are sleeved on the studs. The studs need to be adjusted first in the assembly operation. First, the first assembly body 11 is moved to drive the first assembly part 12 to extend relative to the second assembly part 22. At this time, the first assembly part 12 can be connected to the first component 200, that is, the first assembly part 12 is connected to the studs and is used to rotate the studs to achieve the assembly operation of the studs; after completing the assembly of the studs, the first assembly body 11 is moved to drive the first assembly part 12 to retract into the second assembly part 22. At this time, the second assembly part 22 can be connected to the second component 300, that is, the second assembly part 22 is connected to the nut and is used to rotate the nut to achieve the assembly operation of the nut.

[0054] By adopting the above technical solution:

[0055] First, the two assembly tools are integrated into one switching assembly tool 100, which reduces the number of tools and space occupied by workers during assembly and improves the convenience of carrying tools.

[0056] Secondly, different assembly parts can be switched by relatively moving the first assembly part 1 and the second assembly part 2, thereby reducing the waste of operation actions caused by replacing different assembly tools and improving the convenience of operation;

[0057] Finally, the first assembly portion 12 can be extended or retracted relative to the second assembly portion 22 to realize the switch assembly of two different vehicle components, which simplifies the assembly operation and improves the assembly efficiency.

[0058] Please refer again Figure 2 and Figure 3 In one embodiment, the first assembly part 1 also includes a first limiting portion 13 provided on the first assembly body 11, and the second assembly part 2 also includes a second limiting portion 24 provided on the second assembly body 21; the first limiting portion 13 is connected to the second limiting portion 24 when the first assembly part 12 is retracted and extended to limit the current position relationship of the first assembly part 12 relative to the second assembly part 22.

[0059] Here, it can be understood that the first limiting portion 13 refers to a component used to limit the movement of the first assembly part 1; the first limiting portion 13 is arranged on the first assembly body 11; optionally, the first limiting portion 13 is convexly arranged on the surface of the first assembly body 11, and the protruding direction of the first limiting portion 13 is perpendicular to the axial direction X of the second assembly body 21; the second limiting portion 24 refers to a component used to cooperate with the first limiting portion 13 to limit the movement of the first assembly part 1; the second limiting portion 24 is arranged on the second assembly body 21; optionally, the second limiting portion 24 is concavely arranged on the surface of the second assembly body 21, and the concave direction of the second limiting portion 24 is perpendicular to the axial direction X of the second assembly body 21; in this embodiment, the first limiting portion 13 and the second limiting portion 24 are connected by concave-convex cooperation. When the first assembly part 12 is retracted relative to the second assembly part 22, the first limiting portion 13 is just connected to the second limiting portion 24, so that the first assembly part 12 stays in a position retracted relative to the second assembly part 22. When the first assembly portion 12 extends relative to the second assembly portion 22 , the first limiting portion 13 is just connected to the second limiting portion 24 , so that the first assembly portion 12 stays at a position extending relative to the second assembly portion 22 .

[0060] By adopting the above technical solution, the cooperation between the first limiting portion 13 and the second limiting portion 24 enables the first assembly portion 12 to stay in a position extended or retracted relative to the second assembly portion 22, avoiding accidental switching of the switching assembly tool 100 and improving the stability of the use of the switching assembly tool 100.

[0061] In one embodiment, there are two second limiting portions 24, which are arranged in sequence along the axial direction X of the second assembly body 21, wherein the position of one second limiting portion 24 corresponds to the extended position of the first assembly portion 12, and the position of the other second limiting portion 24 corresponds to the retracted position of the first assembly portion 12.

[0062] Here, it can be understood that the two second limiting portions 24 correspond to the extended position and the retracted position of the first assembly portion 12, respectively; that is, when the first limiting portion 13 moves along with the first assembly body 11 to connect with the second limiting portion 24 corresponding to the extended position of the first assembly portion 12, the second limiting portion 24 limits the first assembly portion 12 to the extended position; similarly, when the first limiting portion 13 moves along with the first assembly body 11 to connect with the second limiting portion 24 corresponding to the retracted position of the first assembly portion 12, the second limiting portion 24 limits the first assembly portion 12 to the retracted position.

[0063] By adopting the above technical solution, the two second limiting portions 24 respectively correspond to the extended and retracted positions of the first assembly portion 12 relative to the second assembly portion 22 , which facilitates the first assembly portion 12 to switch to different positions.

[0064] In one embodiment, the second limiting portion 24 includes a limiting hole 241 provided on the second assembly body 21; the first limiting portion 13 includes a limiting bead seat 131 and a limiting bead 132 provided on the limiting bead seat 131, the limiting bead seat 131 is provided on the first assembly body 11, the limiting bead 132 is elastically connected to the limiting bead seat 131, and the limiting bead 132 is used to be inserted into the limiting hole 241 under the action of elastic force to limit the current position relationship of the first assembly portion 12 relative to the second assembly portion 22.

[0065] Here, it can be understood that the second limiting portion 24 includes a limiting hole 241, which is opened on the second assembly body 21, and the aperture of the limiting hole 241 is slightly smaller than the size of the limiting bead 132, so that when the limiting bead 132 is inserted into the limiting hole 241, the hole wall of the limiting hole 241 can exert a force on the limiting bead 132, thereby limiting the limiting bead 132 in the limiting hole 241; when the worker exerts a force exceeding the force exerted by the hole wall of the limiting hole 241, the first assembly body 11 can drive the limiting bead 132 to disengage from the limiting hole 241. At this time, the first assembly body 11 drives the first assembly part 12 to move freely, and the first assembly part 12 can move to an extended or retracted position, and the limiting bead 132 is re-inserted into the corresponding limiting hole 241 under the action of elastic force.

[0066] By adopting the above technical solution, the first limiting portion 13 and the second limiting portion 24 have simple structures and strong operational reliability.

[0067] Please also read Figure 6 In one embodiment, the second assembly part 2 also includes a guide groove 25 provided on the second assembly body 21 and extending along the axial direction X of the second assembly body 21, and the first assembly part 1 also includes a guide portion 14 provided on the first assembly body 11, and the guide portion 14 is slidably provided in the guide groove 25, and the guide groove 25 is used to limit the guide portion 14 to limit the first assembly body 11 from rotating around the axis of the second assembly body 21.

[0068] Here, it can be understood that the guide groove 25 refers to a groove structure used to guide the moving direction of the first assembly body 11 and limit the rotation of the first assembly body 11 relative to the second assembly body 21; the guide groove 25 is opened on the second assembly body 21, and the length direction of the guide groove 25 is parallel to the axial direction X of the second assembly body 21. In this way, by slidingly connecting the guide portion 14 provided on the first assembly body 11 with the guide groove 25, the groove wall of the guide groove 25 can guide the first assembly body 11 to move along the axial direction X of the second assembly body 21, and at the same time, the groove wall of the guide groove 25 can limit the rotation of the first assembly body 11 around the axis of the second assembly body 21, thereby avoiding the relative rotation between the two and causing the failure of the assembly operation.

[0069] Specifically, the guide portion 14 may be a top screw, that is, the guide portion 14 may be threadedly connected to the first assembly body 11 .

[0070] By adopting the above technical solution, the cooperation between the guide groove 25 and the guide portion 14 guides the movement of the first assembly body 11, thereby improving the stability of the movement of the first assembly body 11; in addition, the cooperation between the guide groove 25 and the guide portion 14 limits the rotation of the first assembly body 11 relative to the second assembly body 21, thereby avoiding failure of the assembly operation.

[0071] In one embodiment, a handle portion exposed in the guide groove 25 is provided on the guide portion 14 .

[0072] Here, it can be understood that the handle can be used as a force-applying structure when a worker moves the first assembly part 1 , and the worker holds the handle to drive the entire first assembly part 1 to move relative to the second assembly part 2 .

[0073] Specifically, the handle portion and the guide portion 14 may be formed integrally.

[0074] By adopting the above technical solution, it is convenient for workers to move the first assembly part 1 , thereby improving the convenience of operating the first assembly part 1 .

[0075] In one embodiment, the guide portion 14 corresponds to the position of the first limiting portion 13 .

[0076] Here, it can be understood that since the guide portion 14 is exposed outside the guide groove 25, the guide portion 14 can be used to indicate whether the first limit portion 13 is inserted into the second limit portion 24; specifically, the guide portion 14 corresponds to the position of the first limit portion 13, so that when the worker sees that the guide portion 14 is aligned with the second limit portion 24, it means that the first limit portion 13 is successfully inserted into the second limit portion 24, and the worker can proceed to the next assembly operation.

[0077] By adopting the above technical solution, it is helpful for workers to determine whether the first assembly part 1 is in the correct position, thereby improving the reliability of the assembly operation.

[0078] In one embodiment, the first assembly member 1 further includes a connection portion 16 for connecting an external tool, and the connection portion 16 is disposed on an end of the first assembly body 11 facing away from the first assembly portion 12 .

[0079] Here, it can be understood that the external tool includes but is not limited to a ratchet or an electric wrench, and the connecting portion 16 of this embodiment can be a standard interface, so that the external tool is connected to the connecting portion 16 to achieve the applicability of the switch assembly tool 100.

[0080] By adopting the above technical solution, it is convenient to switch the connection between the assembly tool 100 and the external tool.

[0081] In one embodiment, the first assembly portion 12 and the second assembly portion 22 are sleeve structures of different sizes, respectively, and the sleeve structures are hexagonal sleeves or plum blossom sleeves.

[0082] Here, it can be understood that the first assembly part 12 and the second assembly part 22 are used to assemble hexagonal nuts or plum blossom bolts; in the present embodiment, the first assembly part 12 can be a hexagonal sleeve structure or a plum blossom sleeve structure, and the second assembly part 22 can be a hexagonal sleeve structure or a plum blossom sleeve structure. The size of the first assembly part 12 is smaller than that of the second assembly part 22, so that the first assembly part 12 can be retracted into the second assembly part 22.

[0083] By adopting the above technical solution, the switch assembly tool 100 of this embodiment can be used to assemble two different nuts or bolts, and has strong applicability.

[0084] In a second aspect, a vehicle assembly device is provided, comprising an external tool and the above-mentioned switch assembly tool 100 , wherein the external tool and the switch assembly tool 100 are detachably connected.

[0085] By adopting the above technical solution, on the basis of having the advantages of the switch assembly tool 100 of the above embodiment, the vehicle assembly device of this embodiment also has the advantages of strong assembly applicability and high assembly efficiency.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
