[0026] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the three-dimensional structure of a quick-release connection mechanism 100 according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic structural diagram of the quick-release connection mechanism 100 in a disassembled state; Figure 3 yes Figure 1 A schematic structural diagram of a quick-release connection mechanism 100 in a cross-sectional state. An embodiment of the present invention provides a quick-release connection mechanism 100 applied to a vehicle model, wherein the quick-release connection mechanism 100 includes a mounting assembly 10 and a fixing assembly 20. The mounting assembly 10 includes a mounting seat 11 and a connecting column 12, wherein the connecting column 12 is connected to the mounting seat 11, wherein a slot 121 is provided on the outer peripheral surface of the connecting column 12, and wherein the mounting seat 11 is used to be connected to a vehicle shell. The fixing assembly 20 includes a fixed shell 21, a rotating member 22, and a clamping block 23, wherein the fixed shell 21 is provided with a mounting hole 211 and is used to be connected to a chassis, wherein the clamping block 23 is movably disposed in the fixed shell 21 and is provided with a rack 231, wherein the rotating member 22 is passed through the fixed shell 21 and is provided with a gear 223 meshing with the rack 231, wherein the rotating member 22 can rotate around its own axis to drive the clamping block 23 to move to a first position or a second position.

[0027] When the mounting seat 11 and the fixing shell 21 are in the installed state, the connecting column 12 extends from the mounting hole 211 into the fixing shell 21, and the block 23 is in the first position and is located in the slot 121 to restrict the connecting column 12 from leaving the fixing shell 21; when the block 23 moves from the first position to the second position, the block 23 leaves the slot 121 to release the restriction on the connecting column 12.

[0028] Specifically, in order to facilitate the connection of the mounting seat 11 and the fixing shell 21 to the vehicle shell and the chassis respectively, the mounting seat 11 is arranged on the top side of the fixing shell 21. The mounting seat 11 can be connected and fixed to the vehicle shell by bolts, screws, pins and other structures, and the fixing shell 21 can be connected and fixed to the chassis by bolts, screws, pins and other structures. The card slot 121 on the outer peripheral surface of the connecting column 12 extends in the circumferential direction, and its corresponding arc is 180°.

[0029] Specifically, the rack 231 of the clamping 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 clamping block 23, that is, the motion of the clamping block 23 between the first position and the second position is a linear motion.

[0030] It should be noted that there can be multiple first positions, and the block 23 can extend into the slot 121 in multiple first positions to restrict the connection column 12 from leaving the fixed shell 21. There can be multiple second positions, and the block 23 can leave the slot 121 in multiple first positions to release the restriction on the connection column 12. It can be understood that when the block 23 is located in the slot 121, if the connection column 12 moves in the direction of exiting the mounting hole 211, the block 23 will abut against the inner wall of the slot 121 to restrict the connection column 12 from leaving the fixed shell 21.

[0031] By setting a split mounting seat 11 and a fixed shell 21, the mounting seat 11 is used to connect with the vehicle shell, and the fixed shell 21 is used to connect with the chassis. The user can assemble the mounting seat 11 and the fixed shell 21 together so that the connecting column 12 on the mounting seat 11 extends into the fixed shell 21 through the mounting hole 211, and then rotate the rotating member 22 to drive the block 23 to move to the first position, so that the block 23 extends into the slot 121, so as to limit the connecting column 12 from leaving the fixed shell 21. The mounting seat 11 and the fixed shell 21 are relatively fixed, thereby completing the assembly of the vehicle shell and the chassis. The user can also drive the block 23 to move to the second position by rotating the rotating member 22, so that the block 23 leaves the slot 121, so as to release the restriction on the connecting column 12, and the mounting seat 11 and the fixed shell 21 can be separated, thereby completing the disassembly of the vehicle shell and the chassis. In this way, the user does not need additional tools for disassembly and assembly, which simplifies the disassembly and assembly of the vehicle shell and the chassis and improves the user experience.

[0032] In one embodiment of this implementation, please refer to Figures 2 to 4 , Figure 4 yes Figure 1The schematic diagram of the structure of the installation component 10 in the quick-release connection mechanism 100 in the disassembled state. The fixing component 20 includes a first elastic member 24, which is disposed in the fixing shell 21 and connected to the card block 23. The first elastic member 24 provides an elastic force to the card block 23 to move toward the first position. In this way, the first elastic member 24 can provide an elastic force to the card block 23 to move from the second position to the first position, so that the user does not need to use the rotating member 22 to move the card block 23 from the second position to the first position to achieve the installation of the mounting seat 11 and the fixing shell 21, which is conducive to improving the user experience. At the same time, the elastic force provided by the first elastic member 24 can keep the card block 23 in cooperation with the card slot 121 to improve the reliability of the installation.

[0033] In one embodiment of this implementation, please refer to Figures 2 to 4 The fixed assembly 20 includes a sliding block 25, which is fixed to the fixed shell 21. The block 23 is provided with a slide groove 232. The sliding block 25 is slidably matched with the slide groove 232. The first elastic member 24 is provided in the slide groove 232. One end of the first elastic member 24 abuts against the sliding block 25, and the other end of the first elastic member 24 abuts against the inner wall of the slide groove 232. In this way, the sliding block 25 can be used to guide the movement of the block 23, and the first elastic member 24 can also be stored in the block 23, thereby reducing the volume of the fixed shell 21.

[0034] In this embodiment, the first elastic member 24 is disposed on a side of the sliding block 25 facing away from the rotating member 22, and the first elastic member 24 is in a compressed state to apply an elastic force to the clamping block 23 toward the axis of the mounting hole 211. It can be understood that when the clamping block 23 is in the first position, one side of the sliding block 25 abuts against the side wall of the slide groove 232 close to 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 member 24.

[0035] In one embodiment of this implementation, please refer to Figures 2 to 4 A sliding protrusion 233 is provided on the side of the block 23 facing away from the rack 231, and 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 block 23 slides along the inner wall to the first position or the second position. Specifically, the sliding protrusion 233 is provided in plurality, and the plurality of sliding protrusions 233 abut against the inner wall of the fixed shell 21. By providing the sliding protrusion 233, the sliding protrusion 233 can abut against the inner wall of the fixed shell 21 to guide the movement of the block 23. At the same time, the fixed shell 21 can be used to limit the block 23, so that the rack 231 on the block 23 can be meshed with the gear 223 on the rotating member 22, thereby improving the stability of the transmission. In addition, by abutting the sliding protrusion 233 against the inner wall of the fixed shell 21, the connection strength between the block 23 and the fixed shell 21 can be improved.

[0036] In one embodiment of this implementation, please refer to Figures 2 to 4 The block 23 is provided with an annular bayonet 234 that can cooperate with the slot 121. When the block 23 is in the first position, the annular bayonet 234 is opposite to the mounting hole 211. Specifically, the shape of the annular bayonet 234 matches the shape of the slot 121. By providing the annular bayonet 234, the annular bayonet 234 can better contact with the slot 121, and can better limit the connection column 12 from leaving the fixed shell 21. At the same time, when the block 23 is in the first position, the annular bayonet 234 is opposite to the mounting hole 211, so that when the block 23 is in the first position, the annular bayonet 234 can extend into the slot 121 to limit the connection column 12 from leaving the fixed shell 21.

[0037] In one embodiment of this implementation, please refer to Figures 2 to 4 The annular bayonet 234 has a guide surface 2341. When the connecting column 12 extends from the mounting hole 211 into the fixed shell 21, the connecting column 12 abuts against the guide surface 2341 and pushes the block 23 to move from the first position to the second position. With such a configuration, during the installation process, the user can insert the connecting column 12 into the mounting hole 211 without rotating the rotating member 22. At the same time, in conjunction with the first elastic member 24, when the user inserts the connecting column 12 into the mounting hole 211, the block 23 can overcome the elastic force of the first elastic member 24 and leave the first position. After the connecting column 12 is inserted, the block 23 can be reset to the first position under the action of the first elastic member 24 to limit the connecting column 12 from leaving the fixed shell 21. The assembly is relatively simple, which is conducive to improving the user experience.

[0038] In this embodiment, the bottom end of the connecting column 12 is constructed as a cone so that the conical surface and the guide surface 2341 can fit together, so that the connecting column 12 can better push the block 23 to move from the first position to the second position during the process of inserting the connecting column 12 into the mounting hole 211.

[0039] In one embodiment of this implementation, please refer to Figures 2 to 4 , the number of the block 23, the mounting hole 211 and the connecting column 12 are all two, the two blocks 23 are connected to the rotating member 22, and the two connecting columns 12 extend into the fixed shell 21 from the corresponding mounting holes 211 respectively. When the rotating member 22 rotates around its own axis, it can drive the two blocks 23 to move in opposite directions and respectively cooperate with the corresponding slots 121 of the connecting column 12. Such a setting can improve the connection strength of the mounting seat 11 and the fixed shell 21 after installation, and at the same time, the user can complete the restriction or contact restriction of the two connecting columns 12 while rotating the rotating member 22, which is relatively simple to operate and is conducive to improving the user experience.

[0040] In one embodiment of this implementation, please refer to Figures 2 to 4The quick-release connection mechanism 100 includes an annular sealing plug 30, which is arranged around the mounting hole 211. The sealing plug is connected to the mounting seat 11 and the fixed shell 21 on both sides in the axial direction. This arrangement can reduce the risk of dust and other debris entering the fixed shell 21 from the mounting hole 211, thereby increasing the service life of the quick-release connection mechanism 100.

[0041] In one embodiment of this implementation, please refer to Figures 2 to 4 The fixing assembly 20 includes a push rod 26 and a second elastic member 27. The push rod 26 is movably arranged in the fixing shell 21 and is opposite to the mounting hole 211. The second elastic member 27 is installed in the fixing shell 21 and connected to the push rod 26. The second elastic member 27 is used to apply an elastic force toward the mounting hole 211 to the push rod 26. After the block 23 leaves the slot 121, the push rod 26 can push the connecting column 12 out of the mounting hole 211. In this way, after the block 23 releases the restriction of the connecting column 12, the connecting column 12 can be pushed out by the push rod 26, thereby completing the disassembly of the mounting seat 11. The disassembly is relatively simple, which is conducive to improving the user experience.

[0042] 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 push rod 26, and the second elastic member 27 is in a compressed state. The fixed shell 21 is provided with a limiting boss 212, and the limiting boss 212 abuts against the push rod 26 to limit the push rod 26 from leaving the fixed shell 21.

[0043] It can be understood that, in the process of the connecting column 12 extending from the mounting hole 211 into the fixed shell 21, the connecting column 12 abuts against the push rod 26, and the connecting column 12 drives the push rod 26 to compress the second elastic member 27, and the connecting column 12 abuts against the block 23, and the connecting column 12 drives the block 23 to compress the first elastic member 24.

[0044] In one embodiment of this implementation, please refer to Figures 2 to 4 The rotating member 22 includes a knob 221 and a rotating rod 222. The knob 221 is disposed on the side of the fixed housing 21 facing away from the mounting seat 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 turn the knob 221 to drive the block 23 to move between the first position and the second position.

[0045] In one embodiment of this implementation, please refer to Figure 2 , Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic structural diagram of the fixing assembly 20 in the quick-release connection mechanism 100 in a disassembled state; Figure 6 yes Figure 1A schematic diagram of the structure of the fixing component 20 in the quick-release connection mechanism 100 after partially hiding the fixing shell 21. The mounting component 10 includes a first electrical connector 13, which is disposed on the mounting seat 11 and is used to electrically connect to electrical components on the vehicle shell. The fixing component 20 includes a second electrical connector 28, which is disposed on the fixing shell 21 and is used to electrically connect to control components on the chassis. When the mounting seat 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 seat 11 and the fixing shell 21 are in the disassembled state, the first electrical connector 13 and the second electrical connector 28 are separated.

[0046] Specifically, the electrical components may be selected from components such as vehicle lights and motors. The control components may be selected from components such as power supply circuit boards and controllers. In this embodiment, the first electrical connector 13 is electrically connected to the vehicle lights on the vehicle shell through cables, and the second electrical connector 28 is connected to the power supply circuit board on the chassis through cables. When the first electrical connector 13 and the second electrical connector 28 are connected, the power supply circuit board and the vehicle lights are connected.

[0047] With such a configuration, the control components and electrical components can be connected while the mounting base 11 and the fixed shell 21 are installed, and the control components and electrical components can be disconnected after the mounting base 11 and the fixed shell 21 are removed. Compared with the traditional method of directly connecting the control components and electrical components with cables, wiring is simpler, which is conducive to improving user experience.

[0048] In this embodiment, a reinforcing column 213 is provided on the fixing shell 21, and a reinforcing hole 111 is provided on the mounting seat 11. After the mounting seat 11 and the fixing shell 21 are installed, the reinforcing column 213 can extend into the reinforcing hole 111 and cooperate with the reinforcing hole 111, thereby improving the connection strength between the mounting seat 11 and the fixing shell 21.

[0049] In one embodiment of this implementation, please refer to Figure 2 , Figure 5 and Figure 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 to electrically connect to the electrical component. In this way, the first magnet 131 and the second electrical connector 28 can be adsorbed and connected to improve the reliability of electrical contact. At the same time, the first conductive sheet 132 can be used to connect a cable so as to facilitate electrical connection with the electrical component through the cable.

[0050] In one embodiment of this implementation, please refer to Figure 2 , Figure 5 and Figure 6The second electrical connector 28 includes a second magnet 281 and a second conductive sheet 282. The second magnet 281 is mounted on the fixed shell 21 and connected to the second conductive sheet 282. The second conductive sheet 282 is used to be electrically connected to the control component. In this way, the second magnet 281 and the first electrical connector 13 can be adsorbed and connected to improve the reliability of electrical contact. At the same time, the second conductive sheet 282 can be used to connect a cable so as to facilitate electrical connection with the control component through the cable.
