Description

Technical Field

[0001] The present application relates to the technical field of vehicle manufacturing, and in particular to a position limiting cooperation device, and a vehicle provided with the position limiting cooperation device. Background Art

[0002] Due to the needs of transporting goods, the tailgate opening angle is usually required to be as large as possible. When the tailgate is opened to 270°, in order to prevent the double-opening tailgate from hitting the side body of the car body during the opening process and causing the tailgate to be accidentally closed due to non-human operation, a limit matching device is usually added.

[0003] Currently, most of the limiting cooperation devices on the market adopt a back door limiting structure and a side panel limiting structure including magnetic adsorption. However, the contact surface of the back door limiting structure and the side panel limiting structure is a plane, resulting in a limited contact area between the two. The magnetic attraction force is likely to have an area of ​​stress concentration on the contact surface, which is not only likely to cause impact loss between the back door limiting structure and the side panel limiting structure, but also likely to result in poor limiting and fixing effects between the two, resulting in the problem of back door limiting failure.

[0065] The present application provides a position limiting cooperation device and a vehicle.

[0066] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0067] like Figure 1-Figure 9 As shown, an embodiment of the present application provides a limiting cooperation device, which includes a back door limiting structure 1 and a side panel limiting structure 2. The back door limiting structure 1 is installed on the back door body 3 of the vehicle, and the back door limiting structure 1 includes a first limiting portion 111. The side panel limiting structure 2 is installed on the side panel body 4 of the vehicle, and the side panel limiting structure 2 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 raised portion that cooperates with the recessed portion in limiting. When the back door body 3 is flipped to be close to the side panel body 4, the first limiting portion 111 and the second limiting portion 211 cooperate in limiting and are fixed by magnetic attraction.

[0068] It should be noted that the solution of fixing the first limiting portion 111 and the second limiting portion 211 by magnetic attraction at least includes:

[0069] ① One of the first limiting portion 111 and the second limiting portion 211 is a magnetic member, and the other is a metal member that can be magnetically fixed by the magnetic member;

[0070] ② The first limiting portion 111 is a magnetic member, and a metal member that can be fixed by the magnetic member is disposed on a surface of the second limiting portion 211 on one side away from the first limiting portion 111;

[0071] ③ The first limiting portion 111 is a metal part that can be fixed by a magnetic attraction component, and a magnetic attraction component is provided on a side surface of the second limiting portion 211 away from the first limiting portion 111.

[0072] Optionally, the first limiting portion 111 is a recessed portion, and the second limiting portion 211 is a raised portion. Optionally, the recessed portion is a spherical recess, and the raised portion is a spherical raised portion.

[0073] The present application optimizes the structural form of the first limiting portion 111 and the second limiting portion 211, so that the two are respectively a recessed portion and a raised portion that can be limited and matched, and the contact surface between the recessed portion and the raised portion is an arc-shaped surface, which ensures a reliable contact area between the two compared to the contact surface being a plane in the prior art; due to the increase in the contact area and the fact that the contact surface is an arc-shaped surface, the stress concentration area of ​​the magnetic attraction on the contact surface is avoided, and the magnetic attraction is more evenly dispersed on the contact surface, which not only avoids the impact loss between the back door limiting structure and the side panel limiting structure, but also ensures the limiting and fixing effect of the two, so that the back door limiting structure is firmly and stably fixed to the side panel limiting structure, and then the back door body is firmly and stably fixed to the side panel body, avoiding the problem of limiting failure of the back door body.

[0074] Furthermore, since the contact surfaces of the first limiting portion 111 and the second limiting portion 211 are arc-shaped surfaces, the magnetic fixing surfaces of the first limiting portion 111 and the second limiting portion 211 can be set to an arc-shaped shape that is compatible with the above-mentioned arc-shaped surfaces, thereby ensuring the magnetic fixing area of ​​the two, thereby making the back door limiting structure 1 firmly and stably fixed to the side panel limiting structure 2, and then making the back door body 3 firmly and stably fixed to the side panel body 4, thereby avoiding the problem of limiting failure of the back door body 3.

[0075] Please see attached Figure 6-7 In certain embodiments of the present application, the back door limiting structure 1 includes an elastic member 12, which can drive the first limiting portion 111 to move telescopically to adjust the position of the first limiting portion 111 and the second limiting portion 211.

[0076] It should be noted that the side enclosure limiting structure 2 is fixed to the side enclosure body 4, and the second limiting portion 211 is kept in a fixed position. The elastic member 12 can be any one of a spring, an elastic rubber member, a bellows, etc.

[0077] By arranging the elastic member 12, the first limiting portion 111 has a certain degree of freedom in position adjustment, so that the installation of the back door limiting structure 1 on the back door body 3 and / or the installation of the side panel limiting structure 2 on the side panel body 4 can have a certain amount of assembly error, thereby ensuring that when the back door body 3 is flipped to be close to the side panel body 4, the first limiting portion 111 can always be reliably limited and cooperated with the second limiting portion 211.

[0078] In addition, under the action of the elastic member 12 , when the first limiting portion 111 is turned over to limit contact with the second limiting portion 211 , a certain elastic buffer is provided to prevent the first limiting portion 111 and the second limiting portion 211 from collision and damage.

[0079] Please see attached Figure 4-6In certain embodiments of the present application, the back door limiting structure 1 includes a first limiting member 11, an elastic member 12, a first cover 13, and a magnetic component 14. The first cover 13 includes a first end opening 131 and a second end opening 132 that are relatively positioned. The first limiting member 11 is movably sleeved in the first cover 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 back door 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.

[0080] When the first position-limiting portion 111 is pressed, the first position-limiting portion 111 presses the magnetic component 14 and compresses the elastic member 12, thereby achieving the retraction movement of the first position-limiting portion 111. When the pressing force on the first position-limiting portion 111 disappears, the elastic member 12 restores its own deformation force, and under the action of the elastic member 12 restoring its own deformation force, the magnetic component 14 and the first position-limiting portion 11 are driven to return to the initial position, thereby achieving the extension movement of the first position-limiting portion 111.

[0081] Please see attached Figure 8-9 It should be noted that the side limiting structure 2 includes a second limiting member 21 and a second sheath 22. The second sheath 22 has a third end opening 221 and a fourth end opening 222; the second limiting member 21 is fixedly sleeved on the second sheath 22, and includes a second limiting portion 211 exposed at the third end opening 221. The first limiting member 11 and the second limiting member 21 are both made of metal or metal alloy that can be magnetically attracted; for example, the first limiting member 11 and the second limiting member 21 can be made of stainless steel.

[0082] When the back door body 3 is turned over to the side enclosure body 4, the first limit portion 111 can be subjected to the pressure from the second limit portion 211. When the back door body 3 is turned over to be separated from the side enclosure body 4, the pressure on the first limit portion 111 disappears.

[0083] 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 portion 111 and the second limiting portion 211 together. As described above, the disadvantage of setting at least one of the first limiting member 11 and the second limiting member 21 as a magnetic member, thereby avoiding the disadvantage that the adsorption force between the two is too large and the stability of the overall structure is damaged.

[0084] As described above, the components of the back door limiting structure 1 are simple, easy to produce and process, and quick and easy to assemble. It not only realizes the magnetic fixation of the first limiting portion 111 and the second limiting portion 211, but also realizes the telescopic movement of the first limiting portion 111 driven by the elastic member 12.

[0085] Please see attached Figure 5-6In certain embodiments of the present application, the back door limiting structure 1 includes a limiting sleeve 15 which is sleeved in the first sleeve 13 and has openings at both ends. The opening of the limiting sleeve 15 close to the first end opening 131 is an embedding opening 151; the outer peripheral edge of the embedding opening 151 has a first stop edge 152 extending radially outward. The first limiting member 11 is movably embedded in the limiting sleeve 15, and the first limiting member 11 includes a second stop edge 112 located in the limiting sleeve 15, and the first limiting portion 111 of the first limiting member 11 is exposed in the embedding opening 151. Under the action of the elastic member 12, the first limiting portion 111 can extend and move relative to the embedding opening 151, and the extension displacement of the first limiting portion 111 is limited under the stop cooperation of the second stop edge 112 and the first stop edge 152.

[0086] It should be noted that when the external force applied to the first limiting portion 111 disappears, the elastic member 12 drives the second stop edge 112 to move to engage with the first stop edge 152, and the extension displacement of the first limiting portion 111 relative to the embedding opening 151 is maximum; and at this time, the elastic member 12 is in a natural state or a compressed state.

[0087] By setting the limiting sleeve 15, the first limiting portion 111 can be flexibly and freely telescopically moved in the first sleeve 13; and through the stopping cooperation between the first stopping edge 152 and the second stopping edge 112, it can be ensured that the first limiting portion 111 cannot be separated from the connection with the limiting sleeve 15.

[0088] Please see attached Figure 6-7 In certain embodiments of the present application, the magnetic assembly 14 includes a receiving member 141, two spaced and oppositely arranged clamping plates 142, and a magnetic member 143. The receiving member 141 is formed with a receiving groove 1411. Each clamping plate 142 at least partially extends into the receiving groove 1411 and is limited in the receiving groove 1411. The magnetic member 143 is located in the receiving groove 1411 and is fixed between the two clamping plates 142. The receiving member 141 is connected to the free end of the elastic member 12; the clamping plate 142 receives the first limiting member 11.

[0089] 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 limiter 11 is placed on a side surface of the clamping plate 142 away from the elastic member 12, so that the clamping plate 142 can receive the first limiter 11. The magnetic member 143 is a magnet.

[0090] The components of the magnetic assembly 14 are simple, easy to produce and process, and quick and convenient to assemble. It not only realizes the connection with the elastic member 12, but also realizes the reception and magnetic fixation of the first limit member 11.

[0091] Please see attached Figure 6In some embodiments of the present application, the first stopper 11 is a cylindrical structure with an opening, and a concave portion that is concave toward the opening is formed on a surface of the cylindrical structure opposite to the opening. A surface of the concave portion close to the opening abuts against the clamping plate 142, and the contour shape of the clamping plate 142 abutting against the concave portion is adapted to the contour shape of the concave portion.

[0092] Please see attached Fig. 9 It should be noted that the second stopper 21 is a spherical structure, and the spherical structure protrudes from the surface of the second sheath 22 to form a convex portion. The contour shape of the clamping plate 142 abutting against the concave portion is an arc shape.

[0093] As described above, a reliable contact area between the clamping plate 142 and the recessed portion is achieved, thereby ensuring a reliable and stable receiving effect on the recessed portion.

[0094] Please see attached Figure 6 In some embodiments, the recessed portion abuts against the clamping plate 142 , and there is a gap between the magnetic member 143 and the recessed portion.

[0095] Since there is a gap between the magnetic member 143 and the recessed portion, the magnetic attraction to the first limiting member 11 can be weakened to a certain extent, thereby avoiding the disadvantage that the adsorption force between the first limiting member 11 and the second limiting member 21 is too large and the stability of the overall structure is damaged.

[0096] Please see attached Figure 6-7 In some embodiments, the receiving member 141 includes a limiting column 1412 , which is eccentrically disposed 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 .

[0097] It should be noted that two opposite groove walls of the receiving groove 1411 are connected to receiving plates 1413 extending to the outside of the receiving groove 1411 , and limiting columns 1412 are provided on the two receiving plates 1413 .

[0098] As described above, by the limiting cooperation between the limiting column 1412 and the circumferential side wall of the cylindrical structure, excessive shaking of the receiving member 141 can be avoided, thereby avoiding excessive shaking of the clamping plate 142 and the magnetic member 143, thereby ensuring the stability of the overall structure of the magnetic component 14.

[0099] Please see attached Figure 2 In some embodiments of the present application, the back door limiting structure 1 includes a first screw rod 17 and a first nut 18. The first nut 18 is fixed to the inner side of the back door body 3, and the first screw rod 17 passes through the first mounting hole of the back door body 3 and is locked to the first nut 18 to fix the back door limiting structure 1 to the back door body 3.

[0100] It should be noted that the back door body 3 includes a back door outer plate and a back door inner plate; optionally, a back door reinforcement plate is provided between the back door outer plate and the back door inner plate. Three assembly holes respectively provided on the back door outer plate, the back door reinforcement plate and the back door inner plate are connected to form a first mounting hole; the first mounting hole is an installation through hole having a hole 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.

[0101] As described above, by rotating the first nut 18 to enter the first mounting hole of the tailgate body 3 and locking and fixing the first nut 18 on the inner side of the tailgate body 3 (i.e., inside the body sheet metal), a stable installation effect is achieved in a confined space, thereby solving the installation problem of the tailgate limiting structure 1 on the tailgate body 3 with a thicker profile.

[0102] Please see attached Figure 4 In some embodiments of the present 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.

[0103] It should be noted that the side enclosure body 4 includes a side enclosure outer plate and a side enclosure inner plate; optionally, a side enclosure reinforcement plate is provided between the side enclosure outer plate and the side enclosure inner plate. The three assembly holes respectively provided in the side enclosure outer plate, the side enclosure reinforcement plate and the side enclosure inner plate are connected to form a second mounting hole; the second mounting hole is a mounting through hole with a hole 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.

[0104] As mentioned above, by rotating the second screw rod 24 to enter the second mounting hole of the side enclosure body 4 and locking and fixing the second nut 25 on the inner side of the side enclosure body 4 (i.e., inside the vehicle body sheet metal), a stable installation effect is achieved in a confined space, thereby solving the installation problem of the side enclosure limiting structure 2 on the side enclosure body 4 with thicker profiles.
