Description

Quick-release connection mechanism for vehicle models and vehicle models Technical Field

[0001] This application relates to the field of vehicle model technology, and in particular to a quick-release connection mechanism for vehicle models and a vehicle model. Background Technology

[0002] A vehicle model is a model made based on a real vehicle, according to its proportions. Some highly detailed vehicle models are identical to real vehicles in shape, structure, color, and interior components. In practical applications, vehicle models can be used as decorative items to adorn the environment or collected as souvenirs.

[0003] In existing technologies, the chassis and body of a vehicle model are directly fixed together with screws. Users need to use tools such as screwdrivers to install or disassemble them, which is troublesome and results in a poor user experience. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a quick-release connection mechanism and a vehicle model for use in vehicle models, which can simplify the assembly and disassembly of the chassis and body shell, and improve the user experience.

[0005] In a first aspect, embodiments of this application provide a quick-release connection mechanism for a vehicle model. The quick-release connection mechanism includes: an installation component, including a mounting base and a connecting column, the connecting column being connected to the mounting base, the outer peripheral surface of the connecting column having a slot, and the mounting base being used to connect to a vehicle body; and a fixing component, including a fixing shell, a rotating member, and a locking block, the fixing shell having an installation hole and being used to connect to a chassis, the locking block being movably disposed within the fixing shell and having a rack, the rotating member passing through the fixing shell and having a gear meshing with the rack, the rotating member being rotatable around its own axis to drive the locking block to move to a first position or a second position; when the mounting base and the fixing shell are in the installation state, the connecting column extends into the fixing shell from the installation hole, the locking block is in the first position and located within the slot, thus restricting the connecting column from leaving the fixing shell; when the locking block moves from the first position to the second position, the locking block leaves the slot, thus releasing the restriction on the connecting column.

[0006] The quick-release connecting mechanism provided in the first aspect of this application has at least the following beneficial effects:

[0007] By using a separate mounting base and a fixed housing, the mounting base connects to the vehicle body, and the fixed housing connects to the chassis. Users can assemble the mounting base and fixed housing together, allowing the connecting post on the mounting base to extend into the fixed housing through the mounting hole. Rotating the rotating component moves the locking block to a first position, causing the locking block to extend into a slot, thus preventing the connecting post from leaving the fixed housing. The mounting base and fixed housing are then relatively fixed, completing the assembly of the vehicle body and chassis. Users can also rotate the rotating component to move the locking block to a second position, causing the locking block to leave the slot and releasing the restriction on the connecting post. The mounting base and fixed housing can then be separated, completing the disassembly of the vehicle body and chassis. This eliminates the need for additional tools, simplifying the assembly and disassembly of the vehicle body and chassis and improving the user experience.

[0008] In one embodiment of this implementation, the fixing component includes a first elastic element disposed within the fixing shell and connected to the locking block, the first elastic element providing an elastic force to the locking block to move toward the first position.

[0009] In one embodiment of this implementation, the fixing component includes a sliding block, the sliding block is fixed to the fixing shell, the locking block has a sliding groove, the sliding block slides in cooperation with the sliding groove, a first elastic member is disposed in the sliding groove, one end of the first elastic member abuts against the sliding block, and the other end of the first elastic member abuts against the inner wall of the sliding groove.

[0010] In one embodiment of this implementation, the locking block has a sliding protrusion on the side facing away from the rack, and the sliding protrusion abuts against the inner wall of the fixed shell. When the rotating member rotates around its own axis, the locking block slides along the inner wall to the first position or the second position.

[0011] In one embodiment of this implementation, the card block is provided with an annular opening that can cooperate with the card slot. When the card block is in the first position, the annular opening is opposite to the mounting hole.

[0012] In one embodiment of this implementation, the annular bayonet has a guide surface. When the connecting post extends into the fixing shell from the mounting hole, the connecting post abuts against the guide surface and pushes the locking block from the first position to the second position.

[0013] In one embodiment of this implementation, there are two of each of the locking blocks, the mounting holes, and the connecting posts. Both locking blocks are connected to the rotating member, and the two connecting posts extend into the fixed housing from their respective mounting holes. When the rotating member rotates around its own axis, it can drive the two locking blocks to move in opposite directions and engage with the corresponding slots of the connecting posts.

[0014] In one embodiment of this implementation, the quick-release connection mechanism includes an annular sealing plug, which is disposed around the mounting hole, and the sealing plug is connected to the mounting base and the fixed shell on its two axial sides, respectively.

[0015] In one embodiment of this implementation, the fixing component includes a top rod and a second elastic member. The top rod is movably disposed within the fixing housing and opposite to the mounting hole. The second elastic member is installed in the fixing housing and connected to the top rod. The second elastic member is used to apply an elastic force toward the mounting hole to the top rod. After the locking block leaves the locking slot, the top rod can push the connecting post out of the mounting hole.

[0016] In one embodiment of this implementation, the rotating component includes a knob and a rotating rod. The knob is located on the side of the fixed housing facing away from the mounting base, and the rotating rod is rotatably connected to the fixed housing, with its two ends respectively connected to the knob and the gear.

The mounting base of the quick-release connection mechanism is connected to the body shell, and the fixing shell of the quick-release connection mechanism is connected to the chassis.

[0018] The vehicle model provided by the second aspect of this application has at least the following beneficial effects:

[0019] By incorporating the quick-release connection mechanism of the first aspect of the implementation into the vehicle model, the assembly and disassembly of the body shell and chassis can be simplified, thereby improving the user experience.

[0020] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] Please refer to Figures 1 to 3. Figure 1 is a three-dimensional structural schematic diagram of the quick-release connecting mechanism 100 according to an embodiment of this application; Figure 2 is a structural schematic diagram of the quick-release connecting mechanism 100 in Figure 1 in an exploded state; Figure 3 is a structural schematic diagram of the quick-release connecting mechanism 100 in Figure 1 in a cross-sectional state. This application provides a quick-release connecting mechanism 100 applied to a vehicle model. The quick-release connecting mechanism 100 includes a mounting component 10 and a fixing component 20. The mounting component 10 includes a mounting base 11 and a connecting post 12. The connecting post 12 is connected to the mounting base 11, and a slot 121 is formed on the outer peripheral surface of the connecting post 12. The mounting base 11 is used to connect to the vehicle body. The fixing assembly 20 includes a fixing shell 21, a rotating member 22, and a locking block 23. The fixing shell 21 has a mounting hole 211 for connecting to the chassis. The locking block 23 is movably disposed in the fixing shell 21 and is provided with a rack 231. The rotating member 22 passes through the fixing shell 21 and is provided with a gear 223 that meshes with the rack 231. The rotating member 22 can rotate around its own axis to drive the locking block 23 to move to a first position or a second position.

[0035] When the mounting base 11 and the fixed housing 21 are in the installation state, the connecting post 12 extends into the fixed housing 21 through the mounting hole 211, and the locking block 23 is in the first position and located in the locking groove 121 to restrict the connecting post 12 from leaving the fixed housing 21; when the locking block 23 moves from the first position to the second position, the locking block 23 leaves the locking groove 121 to release the restriction on the connecting post 12.

[0036] Specifically, to facilitate the connection of the mounting base 11 and the fixing shell 21 to the vehicle body and chassis respectively, the mounting base 11 is located on the top side of the fixing shell 21. The mounting base 11 can be connected and fixed to the vehicle body by bolts, screws, pins, or other structures, and the fixing shell 21 can be connected and fixed to the chassis by bolts, screws, pins, or other structures. The groove 121 on the outer peripheral surface of the connecting post 12 extends circumferentially, with a corresponding arc of 180°.

[0037] Specifically, the rack 231 of the locking block 23 meshes with the gear 223 of the rotating member 22, and the rotational motion of the rotating member 22 can be converted into the linear motion of the locking block 23, that is, the motion of the locking block 23 between the first position and the second position is linear motion.

[0038] It should be noted that there can be multiple first positions, and the locking block 23 can extend into the locking groove 121 in multiple first positions to prevent the connecting post 12 from leaving the fixing housing 21. There can also be multiple second positions, and the locking block 23 can leave the locking groove 121 in multiple first positions to release the restriction on the connecting post 12. It can be understood that when the locking block 23 is located in the locking groove 121, if the connecting post 12 moves in the direction of exiting the mounting hole 211, the locking block 23 will abut against the inner wall of the locking groove 121 to prevent the connecting post 12 from leaving the fixing housing 21.

[0039] By setting a split mounting base 11 and a fixing shell 21, the mounting base 11 is used to connect to the vehicle body, and the fixing shell 21 is used to connect to the chassis. The user can assemble the mounting base 11 and the fixing shell 21 together, so that the connecting post 12 on the mounting base 11 extends into the fixing shell 21 through the mounting hole 211. Then, by rotating the rotating component 22, the locking block 23 is moved to the first position, so that the locking block 23 extends into the locking groove 121 to prevent the connecting post 12 from leaving the fixing shell 21. The mounting base 11 and the fixing shell 21 are relatively fixed, thereby completing the assembly of the vehicle body and the chassis. The user can also rotate the rotating component 22 to move the locking block 23 to the second position, so that the locking block 23 leaves the locking groove 121 to release the restriction on the connecting post 12. The mounting base 11 and the fixing shell 21 can be separated, thereby completing the disassembly of the vehicle body and the chassis. In this way, the user does not need additional tools for disassembly and assembly, simplifying the disassembly and assembly of the vehicle body and the chassis and improving the user experience.

[0040] In one embodiment of this implementation, please refer to Figures 2 to 4. Figure 4 is a structural schematic diagram of the installation component 10 in the disassembled state of the quick-release connection mechanism 100 of Figure 1. The fixing component 20 includes a first elastic member 24, which is disposed within the fixing shell 21 and connected to the locking block 23. The first elastic member 24 provides an elastic force to the locking block 23 to move towards a first position. With this configuration, the first elastic member 24 can provide an elastic force to the locking block 23 to move from a second position to a first position, so that the user does not need to use the rotating member 22 to move the locking block 23 from the second position to the first position to achieve the installation of the mounting base 11 and the fixing shell 21, which is beneficial to improving the user experience. At the same time, the elastic force provided by the first elastic member 24 can keep the locking block 23 in cooperation with the slot 121, thereby improving the reliability of the installation.

[0041] In one embodiment of this implementation, referring to Figures 2 to 4, the fixing component 20 includes a sliding block 25, which is fixed to the fixing shell 21. The locking block 23 has a groove 232, and the sliding block 25 slides in conjunction with the groove 232. A first elastic member 24 is disposed in the groove 232, with one end abutting against the sliding block 25 and the other end abutting against the inner wall of the groove 232. This arrangement allows the sliding block 25 to guide the movement of the locking block 23 while simultaneously housing the first elastic member 24 within the locking block 23, reducing the volume of the fixing shell 21.

[0042] In this embodiment, the first elastic element 24 is disposed on the side of the sliding block 25 facing away from the rotating member 22. The first elastic element 24 is in a compressed state to apply an elastic force to the locking block 23 toward the axis of the mounting hole 211. It can be understood that when the locking block 23 is in the first position, one side of the sliding block 25 abuts against the side wall of the slide groove 232 near the rotating member 22, and the other side of the sliding block 25 abuts against the side wall of the slide groove 232 away from the rotating member 22 through the first elastic element 24.

[0043] In one embodiment of this implementation, referring to Figures 2 to 4, the locking block 23 has a sliding protrusion 233 on the side facing away from the rack 231. The sliding protrusion 233 abuts against the inner wall of the fixed shell 21. When the rotating member 22 rotates around its own axis, the locking block 23 slides along the inner wall to a first position or a second position. Specifically, multiple sliding protrusions 233 are provided, and all of them abut against the inner wall of the fixed shell 21. By providing the sliding protrusions 233, the sliding protrusions 233 can abut against the inner wall of the fixed shell 21 to guide the movement of the locking block 23. At the same time, the fixed shell 21 can be used to limit the locking block 23, so that the rack 231 on the locking block 23 can maintain meshing with the gear 223 on the rotating member 22, improving the stability of the transmission. Furthermore, by using the sliding protrusions 233 to abut against the inner wall of the fixed shell 21, the connection strength between the locking block 23 and the fixed shell 21 can be improved.

[0044] In one embodiment of this implementation, referring to Figures 2 to 4, the locking block 23 is provided with an annular locking opening 234 that can cooperate with the locking slot 121. When the locking block 23 is in the first position, the annular locking opening 234 is opposite to the mounting hole 211. Specifically, the shape of the annular locking opening 234 matches the shape of the locking slot 121. By providing the annular locking opening 234, the annular locking opening 234 can make better contact with the locking slot 121, and can better restrict the connecting post 12 from leaving the fixing housing 21. At the same time, and when the locking block 23 is in the first position, the annular locking opening 234 is opposite to the mounting hole 211, so that when the locking block 23 is in the first position, the annular locking opening 234 can extend into the locking slot 121 to restrict the connecting post 12 from leaving the fixing housing 21.

[0045] In one embodiment of this implementation, referring to Figures 2 to 4, the annular bayonet 234 has a guide surface 2341. When the connecting post 12 extends into the fixing shell 21 from the mounting hole 211, the connecting post 12 abuts against the guide surface 2341, pushing the locking block 23 from the first position to the second position. With this configuration, during installation, the user does not need to rotate the rotating component 22 to insert the connecting post 12 into the mounting hole 211. Simultaneously, in conjunction with the first elastic element 24, the locking block 23 can overcome the elastic force of the first elastic element 24 and move away from the first position during the insertion of the connecting post 12 into the mounting hole 211. After the connecting post 12 is inserted, the locking block 23 can return to the first position under the action of the first elastic element 24, thus preventing the connecting post 12 from leaving the fixing shell 21. Assembly is relatively simple, which is beneficial to improving the user experience.

[0046] In this embodiment, the bottom end of the connecting post 12 is constructed as a cone, so that the cone surface and the guide surface 2341 can fit together, so that the connecting post 12 can better push the locking block 23 from the first position to the second position during the process of inserting into the mounting hole 211.

[0047] In one embodiment of this implementation, referring to Figures 2 to 4, there are two locking blocks 23, two mounting holes 211, and two connecting posts 12. Both locking blocks 23 are connected to the rotating member 22. The two connecting posts 12 extend into the fixed housing 21 from their respective mounting holes 211. When the rotating member 22 rotates around its own axis, it drives the two locking blocks 23 to move in opposite directions and engage with the corresponding slots 121 of the connecting posts 12. This arrangement improves the connection strength between the mounting base 11 and the fixed housing 21 after installation. Simultaneously, the user can simultaneously restrict or limit the contact of the two connecting posts 12 by rotating the rotating member 22, making the operation simple and enhancing the user experience.

[0048] In one embodiment of this implementation, referring to Figures 2 to 4, the quick-release connection mechanism 100 includes an annular sealing plug 30, which surrounds the mounting hole 211. The sealing plug is connected to the mounting base 11 and the fixed housing 21 on its two axially aligned sides, respectively. This arrangement reduces the risk of dust and other debris entering the fixed housing 21 through the mounting hole 211, thereby improving the service life of the quick-release connection mechanism 100.

[0049] In one embodiment of this implementation, referring to Figures 2 to 4, the fixing component 20 includes a push rod 26 and a second elastic member 27. The push rod 26 is movably disposed within the fixing housing 21 and faces the mounting hole 211. The second elastic member 27 is mounted on the fixing housing 21 and connected to the push rod 26. The second elastic member 27 is used to apply an elastic force to the push rod 26 toward the mounting hole 211. After the locking block 23 leaves the locking slot 121, the push rod 26 can push the connecting post 12 out of the mounting hole 211. This arrangement allows the connecting post 12 to be pushed out by the push rod 26 after the locking block 23 releases the restriction of the connecting post 12, thereby completing the disassembly of the mounting base 11. Disassembly is relatively simple and improves the user experience.

[0050] In this embodiment, the bottom end of the second elastic member 27 is connected to the bottom wall of the fixed shell 21, and the top end of the second elastic member 27 is connected to the top rod 26. The second elastic member 27 is in a compressed state. The fixed shell 21 is provided with a limiting boss 212, which abuts against the top rod 26 to prevent the top rod 26 from disengaging from the fixed shell 21.

[0051] It is understandable that during the process of the connecting post 12 extending from the mounting hole 211 into the fixed shell 21, the connecting post 12 abuts against the top rod 26, the connecting post 12 drives the top rod 26 to compress the second elastic element 27, and the connecting post 12 abuts against the locking block 23, the connecting post 12 drives the locking block 23 to compress the first elastic element 24.

[0052] In one embodiment of this implementation, referring to Figures 2 to 4, the rotating component 22 includes a knob 221 and a rotating rod 222. The knob 221 is located on the side of the fixed housing 21 facing away from the mounting base 11. The rotating rod 222 is rotatably connected to the fixed housing 21, and its two ends are respectively connected to the knob 221 and the gear 223. This arrangement allows the user to rotate the knob 221 to move the locking block 23 between a first position and a second position.

[0053] In one embodiment of this implementation, please refer to Figures 2, 5, and 6. Figure 5 is a structural schematic diagram of the fixing component 20 in the quick-release connection mechanism 100 of Figure 1 in an disassembled state; Figure 6 is a structural schematic diagram of the fixing component 20 in the quick-release connection mechanism 100 of Figure 1 after the hidden portion fixing shell 21 is installed. The mounting component 10 includes a first electrical connector 13, which is disposed on the mounting base 11 and used for electrical connection with electrical components on the vehicle body. The fixing component 20 includes a second electrical connector 28, which is disposed on the fixing shell 21 and used for electrical connection with control components on the chassis. When the mounting base 11 and the fixing shell 21 are in the installed state, the first electrical connector 13 and the second electrical connector 28 are connected to connect the control components and the electrical components; when the mounting base 11 and the fixing shell 21 are in the disassembled state, the first electrical connector 13 and the second electrical connector 28 are separated.

[0054] Specifically, the electrical components can be selected from vehicle lights, motors, etc. The control components can be selected from power supply circuit boards, controllers, etc. In this embodiment, the first electrical connector 13 is electrically connected to the vehicle lights on the vehicle body via a cable, and the second electrical connector 28 is connected to the power supply circuit board on the chassis via a cable. When the first electrical connector 13 and the second electrical connector 28 are connected, the power supply circuit board and the vehicle lights are switched on.

[0055] This configuration allows the control components and electrical components to be connected while the mounting base 11 and the fixed housing 21 are being installed, and to be disconnected after the mounting base 11 and the fixed housing 21 are being removed. Compared with the traditional method of directly connecting the control components and electrical components with cables, the wiring is simpler and helps to improve the user experience.

[0056] In this embodiment, the fixed shell 21 is provided with a reinforcing post 213 and the mounting base 11 is provided with a reinforcing hole 111. After the mounting base 11 and the fixed shell 21 are installed, the reinforcing post 213 can extend into the reinforcing hole 111 and cooperate with the reinforcing hole 111, thereby improving the connection strength between the mounting base 11 and the fixed shell 21.

[0057] In one embodiment of this implementation, referring to Figures 2, 5, and 6, the first electrical connector 13 includes a first magnet 131 and a first conductive sheet 132. The first magnet 131 is mounted on the mounting base 11 and connected to the first conductive sheet 132. The first conductive sheet 132 is used for electrical connection with the electrical component. This arrangement allows the first magnet 131 and the second electrical connector 28 to be attracted and connected, improving the reliability of the electrical contact. Simultaneously, the first conductive sheet 132 can be used to connect cables, facilitating electrical connection with the electrical component via cables.

[0058] In one embodiment of this implementation, referring to Figures 2, 5, and 6, the second electrical connector 28 includes a second magnet 281 and a second conductive sheet 282. The second magnet 281 is mounted on the fixed housing 21 and connected to the second conductive sheet 282, which is used for electrical connection with the control component. This arrangement allows the second magnet 281 and the first electrical connector 13 to be attracted together, improving the reliability of the electrical contact. Simultaneously, the second conductive sheet 282 can be used to connect cables, facilitating electrical connection with the control component via cables.

[0059] In one embodiment of this implementation, referring to Figures 2, 5, and 6, the mounting base 11 has a mounting groove 112. The first magnet 131 is mounted in the mounting groove 112, and the first conductive sheet 132 is fixed between the first magnet 131 and the bottom wall of the mounting groove 112. This arrangement allows the first conductive sheet 132 to be clamped and fixed by the first magnet 131 and the mounting base 11, and the mounting groove 112 provides positioning for the first magnet 131, thus improving the positional accuracy of the first magnet 131 and the mounting base 11.

[0060] In one embodiment of this implementation, referring to Figures 2, 5, and 6, the fixing shell 21 has a fixing groove 214, the second magnet 281 is installed in the fixing groove 214, and the second conductive sheet 282 is fixed between the second magnet 281 and the bottom wall of the fixing groove 214. This arrangement allows the second conductive sheet 282 to be clamped and fixed by the second magnet 281 and the fixing shell 21, and the fixing groove 214 provides positioning for the second magnet 281, thus improving the positional accuracy of the second magnet 281 and the fixing shell 21.
