[0026] Please refer to Figures 1 - 5, this application provides a limiting device 100, which includes a magnetic attracting member 1 and a limiting main body 2. The limiting main body 2 has a fitting surface 21, and the fitting surface 21 is recessed to form a receiving groove 22. The magnetic attracting member 1 is arranged in the receiving groove 22. The fitting surface 21 is used to fit with the vehicle tailgate and is adsorbed on the vehicle tailgate through the magnetic attracting member 1. The limiting main body 2 further includes a limiting portion 23, and the limiting portion 23 is used to overlap the movable leaf of the hinge. Specifically, the limiting device 100 of the embodiment of this application is adsorbed on the vehicle tailgate through the fitting surface 21, and the movable leaf of the hinge is overlapped by the limiting portion 23 to limit the opening angle of the hinge, so that the opening angle of the hinge remains consistent during the process of the vehicle tailgate locking the vehicle body, reducing the displacement of the tailgate, improving the assembly consistency, and reducing the workload of the adjustment personnel.

[0027] During use, first open the movable leaf of the hinge of the vehicle tailgate, then insert the limiting device 100 into the lower end of the movable leaf, adsorb it on the tailgate through the magnetic attracting member 1 on the fitting surface 21, and then lean the movable leaf against the limiting portion 23, that is, the installation is completed. At this time, since the movement range of the movable leaf is limited by the limiting portion 23, during the process of locking the tailgate, the movable leaf can keep the angle unchanged when it is opened, thereby reducing the displacement of the tailgate, improving the assembly consistency, and reducing the workload of the adjustment personnel. For the limiting device 100 of the embodiment of this application, it is adsorbed on the tailgate through the magnetic attracting member 1, which is convenient for installation and disassembly, and is convenient to take during the operation process.

[0028] Furthermore, the material of the limiting main body 2 can include blackened metal. On the one hand, it can make the magnetic attracting member 1 adsorbed in the receiving groove 22 to improve stability. On the other hand, the magnetic attracting member 1 is magnetically adsorbed in the receiving groove 22, so that the magnetic force in the circumferential direction of the magnetic attracting member 1 and the direction towards the receiving groove 22 cancels each other out, thereby enhancing the magnetic force of the magnetic attracting member 1 towards the vehicle tailgate direction to improve the adsorption force on the tailgate and improve reliability and stability. The maximum length of the limiting main body 2 is 42 mm, with a small volume, a simple structure, and is convenient to take, which can increase the number of applicable vehicle models and improve the versatility. It should be noted that the maximum length is the maximum length of the limiting main body 2 in all directions. By limiting the maximum length of the limiting main body 2 in all directions, the volume of the limiting main body 2 is reduced to simplify the structure, facilitate installation and disassembly, and improve the versatility.

[0029] In an embodiment of this application, the limiting main body 2 further includes a main body portion 25 and a limiting block 24. The fitting surface 21 is located on one side of the main body portion 25 facing the vehicle tailgate, the limiting block 24 is located on the side of the main body portion 25 away from the vehicle tailgate, the limiting portion 23 is arranged on the limiting block 24, and the limiting block 24 is detachably connected to the main body portion 25.

[0030] Specifically, one side of the main body facing the vehicle tailgate is adsorbed to the tailgate through the fitting surface 21, and the side of the main body away from the vehicle tailgate is lapped on the movable leaf of the hinge through the limiting part 23, thereby restricting the pivoting movement of the movable leaf and keeping the opening angle of the movable leaf unchanged. The limiting block 24 is detachably connected to the main body, so as to facilitate later replacement and maintenance, simplify the structure and reduce the cost.

[0031] In one embodiment of the present application, the limiting block 24 and the limiting part 23 are integrally formed, so that the limiting block 24 and the limiting part 23 can be shipped as a whole, simplify the process and improve the production efficiency. In another embodiment, the limiting block 24 and the limiting part 23 can also be detachably connected. By replacing the limiting parts 23 with different lengths to lap the movable leaves of different hinges, the reliability and versatility are improved.

[0032] In a specific embodiment of the present application, the limiting device 100 further includes a fixing member. The limiting block 24 is provided with a groove with an opening facing the main body part 25 and a first locking hole 241 penetrating through the groove. At least part of the main body part 25 is located in the groove, and the main body part 25 is provided with a second locking hole. The fixing member sequentially passes through the first locking hole 241 and the second locking hole to detachably connect the limiting block 24 and the main body part 25.

[0033] Specifically, a part of the main body part 25 is adapted to the groove. Along the direction facing the vehicle tailgate, the size of the main body part 25 is larger than the size of the groove, so as to prevent the limiting block 24 from contacting or abutting against the vehicle tailgate and causing damage to the tailgate. Part of the main body part 25 is embedded in the groove and fixed by a fixing member to improve the reliability and stability. In a specific embodiment, the first locking hole 241 may include a through hole 11 without a thread, the second locking hole may include a threaded screw hole, and the fixing member may include a fixing bolt. The fixing bolt passes through the through hole 11 and is screwed into the screw hole to connect and fix the limiting block 24 and the main body part 25, improving the stability. In another specific embodiment, the first locking hole 241 may also have a thread. In other specific embodiments, the first locking hole 241 and the second locking hole may further include other hole types, and the fixing member may further include other structural members.

[0034] In one embodiment of the present application, the limiting part 23 includes extending arms. Two extending arms are arranged on opposite sides of the limiting block 24, and the extending direction of the extending arms is perpendicular to the movement direction of the movable leaf.

[0035] Specifically, the movable page is overlapped by the extension arms to restrict the movement of the movable page, thereby keeping the angle of the movable page unchanged and improving consistency. The two extension arms are arranged on opposite sides of the limit block 24, so that both opposite ends of the movable page can be restricted by the extension arms, improving reliability and stability. The extension direction of the extension arms is perpendicular to the movement direction of the movable page, so as to increase the resistance to the movable page when the movable page leans against the extension arms, prevent the movable page from sliding or slipping out of the extension arms, thereby improving reliability and stability, ensuring the position of the movable page remains unchanged, and improving consistency.

[0036] In an embodiment of the present application, the limiting device 100 further includes a gasket 3, and the gasket 3 is detachably mounted between the main body portion 25 and the limit block 24.

[0037] Specifically, the gasket 3 is mounted between the main body portion 25 and the limit block 24, which can change the distance between the main body portion 25 and the limit block 24, and further change the distance between the main body portion 25 and the limiting portion 23, thereby changing the distance between the fitting surface 21 and the limiting portion 23, so that the opening angle of the movable page relative to the vehicle tailgate can be adjusted, and the opening angle of the movable page is adjusted by adjusting the thickness of the gasket 3.

[0038] Further, the thickness range of the gasket 3 in the direction towards the main body portion 25 is 0-1 mm, that is, the opening angle of the movable page can be adjusted by replacing gaskets 3 with different thicknesses, making the angle control adjustable. In some embodiments, the thickness of the gasket 3 can include 0.2 mm, 0.3 mm, 0.5 mm, 1.0 mm, etc. In other embodiments, the thickness of the gasket 3 can also include other thickness specifications.

[0039] In an embodiment of the present application, the gasket 3 is provided with a third locking hole, and the fixing member sequentially passes through the first locking hole 241, the second locking hole and the third locking hole to detachably mount the gasket 3 in the groove.

[0040] Specifically, the gasket 3 is fixed in the groove by the fixing member, which can increase the distance between the limiting portion 23 and the tailgate, adjust the opening angle of the movable page, and also facilitate the disassembly of the gasket 3 and the replacement of gaskets 3 with different thicknesses, reducing the later maintenance cost.

[0041] Further, the gasket 3 is arranged in the groove and can abut against the opposite side walls of the groove to fill the entire groove, preventing the position of the gasket 3 from changing and the gasket 3 from detaching during the screwing process of the fixing member, improving stability. In a specific embodiment, the gasket 3 can include a single elliptical hole square gasket 3 with an opening, that is, the third locking hole is an elliptical hole, and the opening faces the fixing member and is adapted to the fixing member. The size of the gasket 3 is 16*16 mm, that is, the corresponding groove size is 16 mm in length and width. In another specific embodiment, the gasket 3 can also include a closed square gasket 3.

[0042] In one embodiment of the present application, the receiving groove 22 extends in a direction perpendicular to the fitting surface 21, and the opening end of the receiving groove 22 faces the vehicle tailgate. In the direction perpendicular to the fitting surface 21, the size of the magnetic element 1 is smaller than the size of the receiving groove 22, so that the magnetic element 1 is spaced from the vehicle tailgate.

[0043] Specifically, the opening end of the receiving groove 22 faces the tailgate of the vehicle, which can enhance the magnetic force of the magnetic component 1 toward the tailgate of the vehicle, so as to improve the adsorption force on the tailgate, and improve reliability and stability. In the direction perpendicular to the fitting surface 21, the size of the magnetic component 1 is smaller than the size of the receiving groove 22, so that the magnetic component 1 is not in the same plane as the fitting surface 21, and is in direct contact with the tailgate of the vehicle through the fitting surface 21, so that the magnetic component 1 is separated from the tailgate by a certain distance, thereby protecting the magnetic component 1, reducing the damage caused by external force to the magnetic component 1, improving the service life of the magnetic component 1, and further improving the reliability and stability of the limiting device 100.

[0044] In one embodiment of the present application, the limiting device 100 further includes a fastener, and the magnetic member 1 is provided with a through hole 11. The fastener passes through the through hole 11 to fix the magnetic member 1 in the receiving groove 22, thereby improving reliability and stability.

[0045] Specifically, the fastener may include a fastening bolt, one end of which is not provided with a thread, and the other end of which is provided with a thread, and the through hole 11 can be passed through by the fastener. The accommodating groove 22 may include an accommodating portion and a fastening portion, the accommodating portion is located on the side facing the fitting surface 21, and the fastening portion is located on the side away from the fitting surface 21. The accommodating portion is used to accommodate the magnetic attraction component 1, and the fastening portion is provided with a thread to facilitate the fastening bolt to tighten and fix, thereby improving the reliability and stability of the connection and fixation between the magnetic attraction component 1 and the accommodating groove 22.

[0046] The limiting device 100 of the embodiment of the present application can be manually assembled, has a small size, is convenient and quick to use, and can control the opening angle of the hinge.

[0047] It should be noted that terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or vertical, but can be slightly inclined; terms such as "parallel" and "perpendicular" do not mean that the fittings are absolutely parallel or perpendicular to each other, but can have a certain angular deviation. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In addition, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the products of the present application are customarily placed during use. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0048] It can be understood that the meaning of "a plurality of" in this article is at least two, such as two, three, etc., unless there are specific restrictive explanations. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices. The term "and / or" merely describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.
