Limiting device and vehicle
[0001] This application claims priority to Chinese Patent Application No. 202510205057.3, filed on February 24, 2025, entitled “Limiting and Matching Device and Vehicle”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of vehicle manufacturing technology, and in particular to a limiting and fitting device, and a vehicle equipped with the limiting and fitting device. Background Technology
[0003] Due to the need for moving goods, the larger the opening angle of the tailgate, the better. When the tailgate is opened to 270°, in order to prevent the split tailgate from hitting the side of the vehicle body during the opening process and to prevent the tailgate from being accidentally closed due to non-human operation, a limiting device is usually added.
[0004] Most of the limiting and engaging devices on the market currently use a back door limiting structure and a side wall limiting structure, which include magnetic adsorption. However, the contact surfaces of the back door limiting structure and the side wall limiting structure are planar, resulting in a limited contact area. The magnetic attraction is prone to stress concentration areas on the contact surface, which not only easily causes impact loss between the back door limiting structure and the side wall limiting structure, but also easily leads to poor limiting and fixing effect of the two, resulting in the problem of back door limiting failure. Summary of the Invention

[0055] This application provides a limiting and matching device and a vehicle.
[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0057] As shown in Figures 1-9, this application embodiment provides a limiting and engaging device, which includes a tailgate limiting structure 1 and a side panel limiting structure 2. The tailgate limiting structure 1 is installed on the tailgate body 3 of the vehicle and includes a first limiting portion 111. The side panel limiting structure 2 is installed on the side panel body 4 of the vehicle and includes a second limiting portion 211. One of the first limiting portion 111 and the second limiting portion 211 is a recessed portion, and the other is a protrusion that limits and engages with the recessed portion. When the tailgate body 3 is flipped to be close to the side panel body 4, the first limiting portion 111 and the second limiting portion 211 are limited and engaged and fixed by magnetic attraction.
[0058] It should be noted that the magnetic fixation scheme between the first limiting part 111 and the second limiting part 211 includes at least the following:
[0059] (1) One of the first limiting part 111 and the second limiting part 211 is a magnetic member, and the other is a metal member that can be magnetically attracted and fixed by the magnetic member;
[0060] (2) The first limiting part 111 is a magnetic suction member, and the second limiting part 211 is provided with a metal part that can be magnetically attracted and fixed by the magnetic suction member on the side surface away from the first limiting part 111.
[0061] (3) The first limiting part 111 is a metal part that can be magnetically attracted and fixed by the magnetic attractant, and the second limiting part 211 is provided with a magnetic attractant on the side surface away from the first limiting part 111.
[0062] Optionally, the first limiting part 111 is a recessed part; the second limiting part 211 is a protruding part. Optionally, the recessed part is a spherical recess, and the protruding part is a spherical protrusion.
[0063] This application optimizes the structural form of the first limiting part 111 and the second limiting part 211, making them a recessed part and a protruding part that can be limited and matched, respectively. The contact surface of the recessed part and the protruding part is an arc-shaped surface, which ensures a reliable contact area between the two compared to the planar contact surface in the prior art. Due to the increase in contact area and the fact that the contact surface is an arc-shaped surface, the stress concentration area of the magnetic attraction force on the contact surface is avoided, and the magnetic attraction force is more evenly distributed on the contact surface. This not only avoids the impact loss between the tailgate limiting structure and the side wall limiting structure, but also ensures the limiting and fixing effect of the two, so that the tailgate limiting structure is firmly and stably fixed to the side wall limiting structure, and thus the tailgate body is firmly and stably fixed to the side wall body, avoiding the problem of limiting failure of the tailgate body.
[0064] Furthermore, since the contact surfaces of the first limiting part 111 and the second limiting part 211 are arc-shaped, the magnetic fixing surfaces of the first limiting part 111 and the second limiting part 211 can be set to an arc shape that matches the aforementioned arc-shaped surface. This ensures the magnetic fixing area of both, thereby making the back door limiting structure 1 securely and stably fixed to the side wall limiting structure 2, and thus making the back door body 3 securely and stably fixed to the side wall body 4, avoiding the problem of limiting failure of the back door body 3.
[0065] Please refer to Figures 6-8. In some embodiments of this application, the back door limiting structure 1 includes an elastic member 12. The elastic member 12 can drive the first limiting part 111 to move telescopically to adjust the position of the first limiting part 111 and the second limiting part 211 in a limiting engagement.
[0066] It should be noted that the side panel limiting structure 2 is fixed to the side panel body 4, and the second limiting part 211 remains in a fixed position. The elastic element 12 can be any one of a spring, an elastic rubber element, a bellows, etc.
[0067] By setting the elastic element 12, the first limiting part 111 has a certain degree of freedom in position adjustment, thereby allowing the installation of the tailgate limiting structure 1 on the tailgate body 3 and / or the side wall limiting structure 2 on the side wall body 4 to have a certain amount of assembly error, ensuring that when the tailgate body 3 is flipped to be close to the side wall body 4, the first limiting part 111 can always reliably cooperate with the second limiting part 211 for limiting.
[0068] Furthermore, under the action of the elastic member 12, when the first limiting part 111 is flipped to make contact with the second limiting part 211, it has a certain elastic buffer to avoid collision damage between the first limiting part 111 and the second limiting part 211.
[0069] Please refer to Figures 4-6. In some embodiments of this application, the tailgate limiting structure 1 includes a first limiting member 11, an elastic member 12, a first sheath 13, and a magnetic component 14. The first sheath 13 includes a first end opening 131 and a second end opening 132 positioned opposite each other. The first limiting member 11 is movably fitted inside the first sheath 13, and the first limiting member 11 includes a first limiting portion 111 exposed at the first end opening 131. One end of the elastic member 12 is fixed to the tailgate limiting structure 1, and the other end is a free end. The magnetic component 14 is connected to the free end of the elastic member 12, and the magnetic component 14 receives the first limiting member 11.
[0070] When the first limiting part 111 is pressed, it presses against the magnetic component 14 and compresses the elastic member 12, thereby retracting the first limiting part 111. When the pressure on the first limiting part 111 disappears, the elastic member 12 recovers its own deformation force, and under the action of the elastic member 12 recovering its own deformation force, it drives the magnetic component 14 together with the first limiting part 11 to return to the initial position, thereby realizing the extension movement of the first limiting part 111.
[0071] Please refer to Figures 8-9. It should be noted that the side-mounted limiting structure 2 includes a second limiting member 21 and a second protective sleeve 22. The second protective sleeve 22 has a third end opening 221 and a fourth end opening 222. The second limiting member 21 is fixedly sleeved on the second protective sleeve 22 and includes a second limiting portion 211 exposed at the third end opening 221. Both the first limiting member 11 and the second limiting member 21 are made of magnetically attractive metal or metal alloy; for example, the first limiting member 11 and the second limiting member 21 can be made of stainless steel.
[0072] When the tailgate body 3 is flipped to the side body 4, the first limiting part 111 is subjected to a resisting force from the second limiting part 211. When the tailgate body 3 is flipped to detach from the side body 4, the resisting force on the first limiting part 111 disappears.
[0073] The first limiting member 11 and the second limiting member 21 are magnetically attracted by the magnetic component 14, thereby magnetically fixing the first limiting part 111 and the second limiting part 211 together. As described above, at least one of the first limiting member 11 and the second limiting member 21 is avoided as a magnetic member, thereby avoiding excessive attraction between the two and causing damage to the stability of the overall structure.
[0074] As shown above, the components of the back door limiting structure 1 are simple, easy to manufacture and process, and quick and easy to assemble. It not only realizes the magnetic fixation of the first limiting part 111 and the second limiting part 211, but also realizes the extension and retraction movement of the first limiting part 111 driven by the elastic element 12.
[0075] Please refer to Figures 5-6. In some embodiments of this application, the back door limiting structure 1 includes a limiting sleeve 15 fitted inside a first sleeve 13 and having openings at both ends. The opening of the limiting sleeve 15 near the first end opening 131 is an insert 151; a first stop edge 152 extends radially outward from the outer peripheral edge of the insert 151. A first limiting member 11 is movably fitted inside the limiting sleeve 15. The first limiting member 11 includes a second stop edge 112 located inside the limiting sleeve 15, and a first limiting portion 111 of the first limiting member 11 is exposed outside the insert 151. Under the action of the elastic member 12, the first limiting portion 111 can extend and move relative to the insert 151, and the extension displacement of the first limiting portion 111 is limited by the stop engagement of the second stop edge 112 and the first stop edge 152.
[0076] It should be noted that when the external force on the first limiting part 111 disappears, the elastic member 12 drives the second stop edge 112 to move to stop and engage with the first stop edge 152, and the extension displacement of the first limiting part 111 relative to the insertion opening 151 is at its maximum; and at this time, the elastic member 12 is in a natural state or a compressed state.
[0077] By setting the limiting sleeve 15, the first limiting part 111 can move flexibly and freely within the first sleeve 13; and by the stop cooperation between the first stop edge 152 and the second stop edge 112, it can be ensured that the first limiting part 111 cannot detach from the connection and cooperation with the limiting sleeve 15.
[0078] Referring to Figures 6-7, in some embodiments of this application, the magnetic component 14 includes a receiving member 141, two spaced-apart and oppositely disposed snap-fit plates 142, and a magnetic element 143. The receiving member 141 is formed with a receiving groove 1411. Each snap-fit plate 142 extends at least partially into and is confined within the receiving groove 1411. The magnetic element 143 is located within the receiving groove 1411 and is fixed between the two snap-fit plates 142. The receiving member 141 is connected to the free end of the elastic member 12; the snap-fit plates 142 receive the first limiting member 11.
[0079] It should be noted that the bottom of the receiving groove 1411 abuts against the free end of the elastic member 12, or is fixedly connected to the free end of the elastic member 12. The first limiting member 11 is placed on the side surface of the snap-fit plate 142 away from the elastic member 12, so that the snap-fit plate 142 receives the first limiting member 11. The magnetic member 143 is a magnet.
[0080] The components of the magnetic assembly 14 are simple, easy to manufacture and process, and quick and easy to assemble. It not only achieves the connection with the elastic element 12, but also achieves the reception and magnetic fixation of the first limiting element 11.
[0081] Please refer to Figure 6. In some embodiments of this application, the first limiting member 11 is a cylindrical structure with an opening. A recessed portion is formed on the side surface of the cylindrical structure opposite to the opening, which is recessed into the opening. The side surface of the recessed portion near the opening abuts against the snap-fit plate 142, and the contour shape of the snap-fit plate 142 abuts against the recessed portion is adapted to the contour shape of the recessed portion.
[0082] Please refer to Figure 9. It should be noted that the second limiting member 21 is a spherical structure, protruding from the surface of the second sheath 22 to form a raised portion. The contour shape of the latching plate 142 abutting the recess is arc-shaped.
[0083] As shown above, a reliable contact area between the snap-fit plate 142 and the recessed part is achieved, ensuring a reliable and stable bearing effect on the recessed part.
[0084] Please refer to Figure 6. In some embodiments, the recess abuts against the snap-fit plate 142, and there is a gap between the magnetic element 143 and the recess.
[0085] Since there is a gap between the magnetic component 143 and the recessed portion, the magnetic attraction force on the first limiting component 11 can be weakened to a certain extent, thereby avoiding excessive attraction force between the first limiting component 11 and the second limiting component 21, which would damage the stability of the overall structure.
[0086] Please refer to Figures 6-7. In some embodiments, the receiving member 141 includes a limiting post 1412, which is eccentrically positioned relative to the central axis of the cylindrical structure and can extend into the internal space of the cylindrical structure to limit the tilt angle of the receiving member 141.
[0087] It should be noted that the two opposite walls of the receiving groove 1411 are connected to receiving plates 1413 extending outward from the receiving groove 1411, and each of the two receiving plates 1413 is provided with a limit post 1412.
[0088] As described above, by limiting the engagement of the limiting post 1412 with the circumferential sidewall of the cylindrical structure, excessive shaking of the receiving part 141 can be avoided, thereby preventing excessive shaking of the snap plate 142 and the magnetic part 143, and ensuring the overall stability of the magnetic assembly 14.
[0089] Please refer to Figure 2. In some embodiments of this application, the tailgate limiting structure 1 includes a first screw 17 and a first nut 18. The first nut 18 is fixed to the inner side of the tailgate body 3, and the first screw 17 passes through the first mounting hole of the tailgate body 3 and is locked to the first nut 18 to fix the tailgate limiting structure 1 to the tailgate body 3.
[0090] It should be noted that the tailgate body 3 includes an outer tailgate panel and an inner tailgate panel; optionally, a tailgate reinforcing plate is provided between the outer tailgate panel and the inner tailgate panel. Three mounting holes respectively opened in the outer tailgate panel, the tailgate reinforcing plate, and the tailgate inner panel are connected to form a first mounting hole; the first mounting hole is a mounting through hole with a diameter larger than the outer diameter of the first screw 17, so as to facilitate the threaded rotation and fixing assembly of the first screw 17.
[0091] As described above, the first nut 18 is rotated into the first mounting hole of the tailgate body 3 and locked and fixed inside the tailgate body 3 (i.e. inside the body sheet metal), thus achieving a stable installation effect in a limited space and solving the installation problem of the tailgate limiting structure 1 on the thicker tailgate body 3.
[0092] Please refer to Figure 4. In some embodiments of this application, the side enclosure limiting structure 2 includes a second screw 24 and a second nut 25. The second nut 25 is fixed to the inner side of the side enclosure body 4, and the second screw 24 passes through the second mounting hole of the side enclosure body 4 and is locked to the second nut 25 to fix the side enclosure limiting structure 2 to the side enclosure body 4.
[0093] It should be noted that the side panel body 4 includes an outer side panel and an inner side panel; optionally, a side panel reinforcing plate is provided between the outer side panel and the inner side panel. Three assembly holes are respectively opened in the outer side panel, the reinforcing plate, and the inner side panel, which are connected to form a second mounting hole; the second mounting hole is a mounting through hole with a diameter larger than the outer diameter of the second screw 24, so as to facilitate the threaded rotation and fixing assembly of the second screw 24.
[0094] As described above, the second screw 24 is rotated into the second mounting hole of the side body 4 and locked in place by the second nut 25 inside the side body 4 (i.e. inside the body sheet metal), thus achieving a stable installation effect in a limited space and solving the installation problem of the side body limiting structure 2 on the side body 4 with thicker profiles.
[0095] Referring to Figures 2 and 6, in some embodiments of this application, the back door limiting structure 1 includes a first sheath 13 and a first base 16 fitted inside the first sheath 13. A first screw 17 is fixed to the first base 16 and extends out of a second end opening 132 of the first sheath 13. The first sheath 13 is circumferentially sealed to at least a portion of the first base 16, and the circumferential edge of the second end opening 132 extends radially outward with a first covering edge 133 to cover the first mounting hole.
[0096] It should be noted that the first base 16 and the first screw 17 are injection molded as a single unit. The first end opening 131 of the first sleeve 13 exposes the first limiting part 111, and the first screw 17 extends from the second end opening 132 of the first sleeve 13. The first base 16 has external threads, and the limiting sleeve 15 has internal threads, and the limiting sleeve 15 is threadedly connected to the first base 16.
[0097] The first covering edge 133 is formed on the lip structure of the first sheath 13, which can cover the first mounting hole and achieve the effects of aesthetics, waterproofing, and corrosion resistance.
[0098] Referring to Figures 4 and 9, in some embodiments of this application, the side-mounted limiting structure 2 includes a second sheath 22 and a second base 23 fitted inside the second sheath 22. A second screw 24 is fixed to the second base 23 and extends out of a fourth end opening 222 of the second sheath 22. The second sheath 22 and at least a portion of the second base 23 are circumferentially sealed, and a second covering edge 223 extends radially outward from the circumferential edge of the fourth end opening 222 to cover the second mounting hole.
[0099] It should be noted that the second base 23 and the second screw 24 are injection molded as a single unit. The two opposite ends of the second sheath 22 have a third end opening 221 and a fourth end opening 222, respectively; the third end opening 221 of the second sheath 22 exposes the second limiting part 211, and the second screw 24 extends from the fourth end opening 222 of the second sheath 22. The side limiting structure 2 includes a third screw 26, which is injection molded as a single unit with the second base 23, and the second limiting member 21 is threadedly connected to the third screw 26.
[0100] The second cover edge 223 is formed on the lip structure of the second sheath 22, which can cover the second mounting hole, and has the effects of aesthetics, waterproofing and corrosion protection.
