[0023] Due to the need for transporting goods, the tailgate opening angle is usually as large as possible. When the tailgate is opened to 270°, in order to prevent the split tailgate from hitting the rear side of the vehicle during the opening process and to prevent the tailgate from being accidentally closed due to non-human operation, a limiting structure is usually added.

[0024] Currently, the connection stability between components of the tailgate limiting structure on the market is not strong, which can easily cause some components to detach from the other parts as the tailgate is closing.

[0025] To solve the above-mentioned technical problems, this utility model proposes a tailgate limiting structure 10.

[0026] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the tailgate limiting structure 10 includes an inner core 100, a first connector 200, a second connector 400, and a ball head 500. The first connector 200 is disposed at one end of the inner core 100, and a first anti-detachment structure 300 is provided between the inner core 100 and the first connector 200. The second connector 400 is disposed at the other end of the inner core 100. The ball head 500 is connected to the second connector 400.

[0027] The technical solution of this utility model provides a first anti-detachment structure 300 between the inner core 100 and the first connector 200. This increases the anti-detachment force between the inner core 100 and the first connector 200, thereby preventing the inner core 100 and the first connector 200 from separating. This also prevents the ball head 500, which is installed on the inner core 100 via the second connector 400, from separating from the first connector 200. Since the tailgate limiting structure 10 is installed via the first connector 200, this solution can prevent the inner core 100 and the first connector 200 from separating, thereby preventing the tailgate limiting structure 10 from failing and ensuring the normal function of the tailgate limiting structure 10.

[0028] It should be noted that in this embodiment, the tailgate limiting structure 10 is installed on the side panel of the vehicle body, that is, the first connecting member 200 is used to connect with the vehicle body. When the tailgate is opened to near the side panel, the tailgate limiting structure 10 fixes the tailgate relatively to the side panel. This solution is described using the tailgate limiting structure 10 installed on the vehicle body as an example. Of course, this solution is not limited to this; in other embodiments, the tailgate limiting structure 10 can also be installed on the tailgate.

[0029] In this embodiment, the ball joint is configured as a magnetic ball joint, so that when the tailgate is opened to near the side panel, the magnetic ball joint can attract the magnetic engagement structure on the tailgate, thereby fixing the tailgate relatively to the side panel. Of course, the ball joint can also be configured as an iron ball joint, with a magnetic engagement groove on the tailgate to accommodate the iron ball joint.

[0030] Optionally, the outer peripheral surface of the first connector 200200 is provided with a first anti-detachment protrusion 210, and the inner core 100 is provided with a first mounting groove 110 corresponding to the first anti-detachment protrusion 210. It can be understood that the first anti-detachment protrusion 210 is provided in the first mounting groove 110, and the groove wall of the first mounting groove 110 will restrict the axial and radial displacement of the first anti-detachment protrusion 210, thereby further increasing the anti-detachment force between the inner core 100 and the first connector 200, preventing the inner core 100 and the first connector 200 from separating, thereby preventing the tailgate limiting structure 10 from failing and ensuring the normal function of the tailgate limiting structure 10.

[0031] Secondly, in this embodiment, the first connector 200 is configured as a connecting bolt, and the first anti-detachment protrusion 210 is formed on the head of the connecting bolt. This increases the anti-detachment force between the inner core 100 and the first connector 200, and facilitates the connection between the first connector 200 and the side panel of the vehicle body. Further, the side panel of the vehicle body can be provided with threaded holes corresponding to the connecting bolts, and the bolts of the connecting bolts can be screwed into the threaded holes. Alternatively, mounting holes can be provided on the vehicle body, with the bolts of the connecting bolts passing through the mounting holes and being fixed to the vehicle body with nuts. Of course, this solution is not limited to this. In other embodiments, the first connector 200 can be configured as a mounting rod, with a radially extending reinforcing protrusion at the end of the mounting rod. The inner core 100 is provided with a limiting groove corresponding to the reinforcing protrusion, and the reinforcing protrusion is located within the limiting groove. This also increases the anti-detachment force between the inner core 100 and the first connector 200. The reinforcing protrusion can be a reinforcing ring protrusion or multiple spaced reinforcing protrusions extending radially along the mounting rod.

[0032] Furthermore, the first anti-detachment structure 300 includes a first anti-detachment recess 310 on the outer peripheral surface of the connecting bolt and a first anti-detachment protrusion 320 on the inner core 100 corresponding to the first anti-detachment recess 310. This anti-detachment structure is simple in construction and easy to mold. Of course, this solution is not limited to this. In other embodiments, the first anti-detachment structure 300 may also include an external thread on the outer peripheral surface of the first connector 200. When the first anti-detachment protrusion 210 is provided, the external thread is located on the outer peripheral surface of the first anti-detachment protrusion 210, and the inner core 100 has an internal thread corresponding to the external thread. Furthermore, the first anti-detachment protrusion 210 of the first connector 200 can be widened, that is, the outer peripheral surface of the first anti-detachment protrusion 210 can be widened, which can further increase the anti-detachment force between the first connector 200 and the inner core 100.

[0033] Optionally, in this embodiment, the tailgate limiting structure 10 further includes a protective sleeve 600. The protective sleeve 600 at least covers one end of the inner core 100 near the ball joint 500 and the portion covering the ball joint 500. The protective sleeve 600 not only protects the ball joint 500 but also prevents the tailgate from colliding with the inner core 100. Of course, this solution is not limited to this. In other embodiments, the protective sleeve 600 may not be provided, and a reasonable distance may be set between the inner core 100 and the ball joint 500 to prevent the tailgate from colliding with the inner core 100.

[0034] Optionally, in this embodiment, a second anti-detachment structure 700 is provided between the sheath 600 and the inner core 100. This increases the anti-detachment force between the inner core 100 and the sheath 600, thereby preventing the inner core 100 and the sheath 600 from separating. It is understood that if the sheath 600 separates from the inner core 100, it may cover the ball joint 500, affecting the fit between the ball joint 500 and the tailgate. Therefore, the second anti-detachment structure 700 between the sheath 600 and the inner core 100 can prevent the tailgate limiting structure 10 from failing and ensure the normal function of the tailgate limiting structure 10. Of course, this solution is not limited to this. In other embodiments, the second anti-detachment structure 700 may not be provided between the sheath 600 and the inner core 100, but a double connection structure may be provided between the sheath 600 and the inner core 100, such as, but not limited to, adhesive and screw connections.

[0035] The second anti-detachment structure 700 includes a second anti-detachment protrusion 710 disposed on the outer peripheral surface of the inner core 100, and a second anti-detachment recess 720 disposed on the sheath 600 corresponding to the second anti-detachment protrusion 710. Such an anti-detachment structure has a simple construction and is easy to manufacture molds. Of course, this solution is not limited to this. In other embodiments, the first anti-detachment structure 300 may also include an external thread disposed on the outer peripheral surface of the inner core 100, and the sheath 600 is provided with an internal thread corresponding to the external thread.

[0036] Reference Figure 2 Furthermore, the first anti-detachment protrusion 320 and / or the second anti-detachment protrusion 710 have a rectangular cross-section in the axial direction of the connecting bolt. This further increases the anti-detachment force between the connecting bolt and the inner core 100, and between the inner core 100 and the sheath 600. Of course, this solution is not limited to this. In other embodiments, the cross-section of the first anti-detachment protrusion 320 and / or the second anti-detachment protrusion 710 in the axial direction of the connecting bolt may be trapezoidal, and the width of the first anti-detachment protrusion 320 and / or the second anti-detachment protrusion gradually increases in the direction towards the free end.

[0037] Furthermore, the inner core 100 and the sheath 600 are subjected to two-color injection molding. Two-color injection molding refers to injecting two different plastic materials in stages within the same production cycle to form an integrated composite product. By connecting and molding the inner core 100 and the sheath 600 through such injection molding process, the fastening force between the two can be strengthened, while reducing the steps of separate molding and installation, thereby helping to improve production efficiency.

[0038] Optionally, the sheath 600 is conical in shape and tapers towards the ball joint 500. This better covers the inner core 100 while reducing the volume of the sheath 600 and minimizing interference when the tailgate and ball joint 500 are engaged. However, this solution is not limited to this; in other embodiments, the sheath 600 may also be cylindrical.

[0039] Furthermore, the sheath 600 is made of a soft material, which can better cushion the impact force of the tailgate.

[0040] Furthermore, the outer peripheral surface of the second connector 400 is provided with a second anti-detachment protrusion 410, and the inner core 100 is provided with a second mounting groove 120 corresponding to the second anti-detachment protrusion 410. It can be understood that the second anti-detachment protrusion 410 is located in the second mounting groove 120, and the groove wall of the second mounting groove 120 will restrict the axial and radial displacement of the second anti-detachment protrusion 410, thereby further increasing the anti-detachment force between the inner core 100 and the second connector 400, preventing the inner core 100 and the second connector 400 from separating, thereby preventing the tailgate limiting structure 10 from failing and ensuring the normal function of the tailgate limiting structure 10.

[0041] Secondly, in this embodiment, the second connector 400 is configured as a mounting bolt, and the second anti-detachment protrusion is formed on the head of the mounting bolt. Further, the ball head 500 can have a threaded hole corresponding to the mounting bolt, and the bolt can be screwed into the threaded hole, thereby increasing the anti-detachment force between the inner core 100 and the second connector 400. This also facilitates the connection between the second connector 400 and the ball head 500, increasing the fastening force between them. Of course, this solution is not limited to this. In other embodiments, the second connector 400 can be configured as a mounting rod, with a radially extending reinforcing protrusion at the end of the mounting rod. The inner core 100 has a limiting groove corresponding to the reinforcing protrusion, and the reinforcing protrusion is located within the limiting groove. The inner core 100 has a mounting groove corresponding to the mounting rod, and the mounting rod and mounting groove are interference-fitted. This also increases the anti-detachment force between the inner core 100 and the second connector 400. The reinforcing protrusion can be a reinforcing ring protrusion or multiple spaced reinforcing protrusions extending radially along the mounting rod.

[0042] Furthermore, the inner core 100 is inserted into the first connector 200 and / or the second connector 400 via injection molding. This is because insert injection molding allows the inner core 100 to fit tightly against the first connector 200 and / or the second connector 400, thereby further increasing the release force between the inner core 100 and the first connector 200, and / or the inner core 100 and the second connector 400. Moreover, the insert injection molding process is simple and can increase production efficiency.
