Description

Technical Field

[0001] This utility model relates to the field of motorcycle component technology, specifically to a modular motorcycle frame that can be quickly disassembled and assembled. Background Technology

[0002] Modular motorcycle frames are a design that breaks down the frame structure into multiple independent modules, which can be combined, replaced, or upgraded according to different needs.

[0003] Chinese utility model patent with authorization announcement number CN206885244U discloses a modularly designed electric motorcycle frame assembly and the electric motorcycle thereof. The motorcycle frame adopts a modular design, which can combine frames of different module styles, improve the commonality of parts, reduce the development cycle of the frame, and reduce the manufacturing cost of the frame.

[0004] However, the motorcycle frame has certain defects in assembly and disassembly. The front, middle and rear component modules in this application are welded together sequentially. Once the modules are fixed by welding, each component module cannot be disassembled or replaced individually, and users cannot adjust the frame structure according to their needs. Therefore, this utility model proposes a modular motorcycle frame that can be quickly disassembled and assembled to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular motorcycle frame that can be quickly disassembled and assembled, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular motorcycle frame that can be quickly disassembled and assembled, including a front frame, a middle frame, and a rear frame;

[0007] The lower frame at both ends of the central frame is provided with limiting grooves, and the upper frame is provided with auxiliary connecting components;

[0008] The front and rear fixed frames are detachably mounted at both ends of the middle fixed frame via the auxiliary connecting assembly.

[0009] The auxiliary connection assembly includes several sets of fixing plates, several sets of first hinge seats, and several sets of second hinge seats. Each pair of fixing plates is welded to the assembly cavity reserved in the middle of the upper frame on both sides of the central frame. Each set of first hinge seats is hinged to a set of fixing plates, and a set of second hinge seats is hinged between each pair of first hinge seats.

[0010] Preferably, the front support frame and the rear support frame are welded together at their ends, and a limiting hole is reserved above the connecting part.

[0011] Preferably, the size of the lower part of the connecting part is fitted into the limiting groove on the lower frame.

[0012] Preferably, the lower end of the second hinge seat has two sets of positioning posts in an integral structure.

[0013] Preferably, the two sets of positioning posts are adapted to the limiting holes reserved above the connecting part.

[0014] Preferably, the auxiliary connection assembly further includes a fixing block and a threaded pin. The fixing block is disposed on multiple sets of first hinge seats. The fixing block has a through hole. The threaded pin can pass through the through hole of the fixing block and connect to the threaded cavity on one set of the fixing plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By using the hinge structure and positioning of the auxiliary connecting components, the problem of the traditional welded modular frame being unable to be disassembled is solved. The lower part of the connection between the front frame and the rear frame is fitted with the limiting groove of the middle frame to achieve initial positioning. The positioning pin of the second hinge seat is inserted into the limiting hole of the connection to complete precise fixation. Then, the overall structure is locked by the threaded pin. Assembly or disassembly can be completed without welding tools. This structure allows users to quickly replace different modules according to their needs, meeting the needs of personalized modification and functional adjustment.

[0017] (2) The lateral displacement is restricted by the fitting of the limiting groove and the connecting part, and the matching of the positioning post and the limiting hole ensures the precise vertical docking. The threaded pin is connected to the screw cavity of the fixing block and the fixing plate, which distributes the stress of the hinge structure to multiple components. At the same time, the fitting of the connecting part and the limiting groove, and the matching of the positioning post and the limiting hole, standardize the interface between modules. This ensures the universal interchangeability of different modules and reduces the risk of vibration and loosening during driving by combining rigid positioning and flexible hinge, thus ensuring the overall structural strength of the frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a modular motorcycle frame that can be quickly disassembled and assembled, including a front frame 1, a middle frame 2, and a rear frame 3. The lower frame at both ends of the middle frame 2 is provided with limiting grooves 21, and the upper frame is provided with auxiliary connecting components 5. The front frame 1 and the rear frame 3 are detachably installed at both ends of the middle frame 2 through the auxiliary connecting components 5. The auxiliary connecting components 5 include several sets of fixing plates 51, several sets of first hinge seats 52, and several sets of second hinge seats 53. Each pair of fixing plates 51 are welded opposite to each other at the assembly cavity reserved in the middle position of the upper frame on both sides of the middle frame 2. Each set of first hinge seats 52 is hinged to a set of fixing plates 51, and a set of second hinge seats 53 is hinged between each pair of first hinge seats 52. The ends of the front frame 1 and the rear frame 3 are welded with connecting parts 4, and limiting holes are reserved above the connecting parts 4.

[0025] Please see Figures 1 to 4 The size of the lower part of the connecting part 4 fits into the limiting groove 21 on the lower frame. When the vehicle is driving, the vibration and impact force generated can be transmitted and dispersed through the fitting part, reducing the stress on the auxiliary connecting component 5, reducing the risk of damage to the connection due to excessive stress over a long period of time, and improving the safety of the overall frame structure.

[0026] Please see Figures 1 to 4 The lower end of the second hinge seat 53 is integrally structured with two sets of positioning posts 55.

[0027] Please see Figures 1 to 4 The two sets of positioning pins 55 are adapted to the limiting holes reserved above the connecting part 4.

[0028] Please see Figures 1 to 4 The auxiliary connection component 5 also includes a fixing block 521 and a threaded pin 54. The fixing block 521 is disposed on multiple sets of first hinge seats 52. The fixing block 521 has a through hole. The threaded pin 54 can pass through the through hole of the fixing block 521 and connect to the threaded cavity on one set of fixing plates 51.

[0029] By using the hinge structure and positioning of the auxiliary connecting component 5, the problem of the indivisibility of traditional welded modular frames is solved. The lower part of the connecting part 4 of the front frame 1 and the rear frame 3 is engaged with the limiting groove 21 of the middle frame 2 to achieve initial positioning. The positioning post 55 of the second hinge seat 53 is inserted into the limiting hole of the connecting part 4 to complete precise fixation. Then, the overall structure is locked by the threaded pin 54. Assembly or disassembly can be completed without welding tools. This structure allows users to quickly replace different modules according to their needs, meeting the needs of personalized modification and functional adjustment.

[0030] When using,

[0031] First, pull the second hinge seat 53 upward, and the first hinge seat 52 rotates. Then, align the lower part of the connecting part 4 at the end of the front frame 1 or the rear frame 3 with the limiting groove 21 of the corresponding lower frame of the middle frame 2, so that the lower part of the connecting part 4 fits into the limiting groove 21, thus completing the initial vertical positioning of the module and limiting the lateral displacement.

[0032] Next, the second hinge seat 53 is restored to the horizontal position, and the first hinge seat 52 is also restored to the horizontal position. At this time, the two sets of positioning pins 55 at the lower end of the second hinge seat 53 are aligned with the reserved limiting holes above the connecting part 4. The positioning pins 55 are inserted into the limiting holes to achieve precise positioning of the module in the horizontal direction. At this time, the connecting part 4 of the front fixed frame 1 or the rear fixed frame 3 and the middle fixed frame 2 forms a stable pre-fixed state.

[0033] Finally, threaded pin 54 is passed through the through hole of fixing block 521 on first hinge seat 52, aligned and screwed into the threaded cavity on one set of fixing plates 51 until threaded pin 54 is fully locked. Through the rigid connection between fixing block 521 and fixing plate 51, the positions of first hinge seat 52 and second hinge seat 53 are fixed, so that the auxiliary connection assembly 5 forms a stable locking structure, completing the assembly of front fixed frame 1 or rear fixed frame 3 with middle fixed frame 2. When it is necessary to disassemble front fixed frame 1 and rear fixed frame 3, simply reverse the above steps to remove front fixed frame 1 and rear fixed frame 3 from middle fixed frame 2.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
