Description

Technical Field

[0001] The utility model relates to the technical field of vehicle tailgates, in particular to a vehicle tailgate limiting mechanism. Background Art

[0002] For vehicle cantilever tailgates, most of them are fixed to the rear beam of the vehicle through a suspension bracket with multiple oil cylinders by a suspension plate, and are operated through an electric control and power unit system to control the tailgate panel to turn backward from a vertical state - to a horizontal state - to descend to the ground - to incline downward until the front end of the panel fits the ground.

[0003] During the use of the vehicle tailgate, it is necessary to limit its lifting height. The prior art mainly adopts the following two limiting methods: 1. Refer to the attached drawings of the specification Figure 5 As shown, two L-shaped limiting plates are installed on the vehicle's main beam and auxiliary beam to limit the lifting arm through the limiting plates; 2. By setting a travel switch to control the opening and closing of the electrical appliance to control the lifting height of the tailgate; both of the above methods have drawbacks. For the method of setting the limiting plates, since the national regulations do not allow welding on the vehicle's main beam and only bolts can be used for fixing, the installation is time-consuming and laborious. However, after the tailgate is used for a period of time, gaps are generated due to wear, resulting in uneven left and right heights of the tailgate. After the heights are inconsistent, it is very difficult to adjust the limiting plates; for the method of setting the travel switch, the travel switch is exposed and easily gets water, causing a short circuit and malfunction. After the tailgate is used and gaps are generated due to wear, resulting in uneven left and right heights of the tailgate, adjustment cannot be performed after the heights become inconsistent. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a vehicle tailgate limiting mechanism.

[0005] The utility model is realized through the following technical solutions:

[0006] A vehicle tailgate limiting mechanism includes two limiting frames fixed on the vehicle. The limiting frame includes:

[0007] A fixed end, which is connected to the vehicle;

[0008] An adjusting end, which is arranged above the fixed end and its end extends above the lifting arm of the vehicle tailgate;

[0009] A limiting member, which is arranged at the end of the adjusting end and the bottom of the limiting member can approach or move away from the lifting arm.

[0010] The further setting of the utility model is that the limiting frame is fixed on the cross beam of the vehicle tailgate, and the cross beam is fixed to the rear main beam of the vehicle.

[0011] The further setting of the utility model is that the adjusting end and the fixed end are inclined.

[0012] A further setting of the utility model is that an adjustment hole is provided at the end of the adjustment end, and the limiting member is arranged in the adjustment hole and its end extends to the lower side of the adjustment end.

[0013] A further setting of the utility model is that the adjustment hole is a threaded hole, the limiting member is a bolt, and the limiting member is threadedly connected to the adjustment hole.

[0029] Referring to Figures 1 to 4 As shown, a vehicle tailgate limiting mechanism includes two limiting frames fixed to the vehicle. The limiting frame includes: a fixed end 200, and the fixed end 200 is connected to the vehicle; an adjusting end 300, the adjusting end 300 is arranged above the fixed end 200 and the end thereof extends above the lifting arm 400 of the vehicle tailgate; a limiting member 500, the limiting member 500 is arranged at the end of the adjusting end 300 and the bottom of the limiting member 500 can approach or move away from the lifting arm 400; in the above technical solution, the limiting frame is an integral structure. Referring to Figure 1As shown, the lifting arm 400 is rotatable. The end of the adjusting end 300 extends above the lifting arm 400, and a limiting member 500 is provided at the end of the adjusting end 300. During the process of the lifting arm 400 rotating and rising, due to the existence of the limiting member 500, when the lifting arm 400 contacts the limiting member 500, the limiting member 500 can play a blocking role to prevent the lifting arm 400 from rotating upward; the bottom of the limiting member 500 can approach or move away from the lifting arm 400, that is, the limiting member 500 can move up and down relative to the adjusting end 300. When the vehicle tailgate has inconsistent left and right heights due to long-term use, since there are two limiting frames, by adjusting the limiting members 500 of the two limiting frames respectively, the rotation and rising stroke of the two lifting arms 400 can be adjusted, so as to ensure that the left and right heights of the vehicle tailgate are the same when it is retracted; compared with the prior art which sets the L-shaped limiting plate 1 and fixes the limiting plate 1 on the vehicle frame and the vehicle auxiliary beam, the structural design of this technical solution is novel and ingenious and is convenient for installation; compared with the travel switch of the prior art, in this technical solution, through the separately adjustable limiting member 500, it can be adjusted according to different requirements to make the left and right heights of the vehicle tailgate the same and more stable; it should be noted that the lifting arm 400 mentioned in this technical solution is the prior art, and its structure can be referred to the accompanying drawings of the specification. Figure 4 , the lifting arm 400 includes an outer arm plate and an inner arm plate, and a sealing plate and other structures are connected between the outer arm plate and the inner arm plate. In this technical solution, the end of the adjusting end 300 extends above the lifting arm 400 of the vehicle tailgate, taking the Figure 4 angle as an example, the end of the adjusting end 300 extends above the lower part of the lifting arm 400 of the vehicle tailgate, that is, above the lower part of the sealing plate.

[0030] Refer to Figure 2 and Figure 3 As shown, the limiting frame is fixed on the cross beam 600 of the vehicle tailgate, and the cross beam 600 is fixed to the rear frame of the vehicle; in the above technical solution, the cross beam 600 of the vehicle tailgate is the main frame part of the vehicle tailgate, and the limiting frame is welded and fixed to the cross beam 600. Refer to Figure 1 As shown, the lower side of the fixed end 200 of the limiting frame has a rectangular notch, which is used for sleeving on the cross beam 600 of the vehicle tailgate, and then the limiting frame is fixed to the cross beam 600 of the vehicle tailgate by welding. As an extension, the lower side of the fixed end 200 has an L-shaped notch, and the fixed end 200 can also be fixed to the cross beam 600 of the vehicle tailgate by welding; for the convenience of understanding, this technical solution introduces the connection method between the cross beam 600 of the vehicle tailgate and the rear frame of the vehicle. Refer to Figure 2 and Figure 3As shown, the rear end of the crossbeam 600 is vertically connected to two longitudinal beams, and the other ends of the two longitudinal beams are connected to the rear bumper of the vehicle. Two connecting frames 700 are fixed to the upper end of the crossbeam 600, and a connecting frame 700 is fixed to each longitudinal beam. Therefore, the crossbeam 600 of the tail plate of the vehicle is fixed to the rear beam of the vehicle through four connecting frames 700 by bolts, that is, the limit frame is fixed to the vehicle through the crossbeam 600, the connecting frame 700 and the rear beam, so that the technical solution is more stable and reliable.

[0031] See also Figures 1 to 3 As shown, the adjusting end 300 and the fixing end 200 are arranged at an angle.

[0032] See also Figure 2 and Figure 3 As shown, an adjustment hole is provided at the end of the adjustment end 300, and the limit member 500 is arranged in the adjustment hole and its end extends to the lower side of the adjustment end 300; in the above technical solution, the limit member 500 is moved up and down relative to the adjustment end 300 through the setting of the adjustment hole.

[0033] As a further preferred solution, the adjustment hole is a threaded hole, the limit member 500 is a bolt, and the limit member 500 is threadedly connected to the adjustment hole; in the above technical solution, the limit member 500 can rotate in the adjustment hole, so that the bottom of the limit member 500 approaches or moves away from the direction of the lifting arm 400. It is worth noting that the bolt head of the limit member 500 is located on the lower side, so that the release area is increased when the lifting arm 400 contacts the limit member 500. Furthermore, as a preference, a buffer pad is bonded to the bottom of the limit member 500. The buffer pad is made of rubber and can play a buffering role to avoid long-term contact between the two and damage as much as possible.

[0034] See also Figures 1 to 3 As shown, the vehicle tailgate limiting mechanism also includes at least one locking member 100, which is connected to the limiting member 500; in the above technical solution, the locking member 100 is a nut, and there are preferably two locking members 100, both of which are threadedly screwed to the limiting member 500 and are respectively located at the upper end of the adjustment end 300 and the lower end of the adjustment end 300, and the two locking members 100 can lock the limiting member 500 to prevent the limiting member 500 from loosening and shaking; and when the limiting member 500 needs to be adjusted, the locking member 100 can also be loosened.

[0035] It should be noted that in the technical solution of a vehicle tailgate limiting mechanism proposed in this application, the vehicle tailgate, the cross beam 600 of the vehicle tailgate, and the lifting arm 400 are all prior arts, which can be selected by those skilled in the art according to actual needs.
