Description

Technical Field

[0001] The utility model relates to the technical field of locking a vehicle back door, in particular to a self-locking back door and a vehicle. Background Art

[0002] Existing garbage trucks generally have a frame, the interior of the frame is hollow to form a compartment in which a garbage bin can be placed, and a rear door is provided at the rear end of the frame. When the rear door is opened, the garbage bin can be exposed.

[0003] In particular, there is a garbage truck whose upper end of the back door is hingedly connected to the frame. When the back door is opened from bottom to top, the garbage bin can be moved out of the vehicle, and when the back door is closed from top to bottom, the garbage bin can be moved into the vehicle, which is convenient for daily work.

[0004] However, since the above-mentioned tailgate is a movable part, there is actually no connection structure between the lower end of the tailgate and the vehicle frame. When the tailgate is closed, it is overlapped on the vehicle frame under the action of gravity, which makes the tailgate less stable in the closed state. During the driving of the vehicle, the tailgate will shake to a certain extent.

[0005] To address the above problem, usually, two sets of magnets are installed on the tailgate and the frame respectively, so that when the tailgate is in the closed state, the tailgate is adsorbed on the frame by the magnetic force of the magnets. However, there is still an unstable factor in fixing the tailgate with the magnetic force of the magnets, especially in bumpy road conditions, where the magnetic force is prone to failure, resulting in the risk of the tailgate coming off.

DETAILED DESCRIPTION

[0033] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0034] First, as Figure 1-6 As shown, this embodiment provides a self-locking tailgate, which includes a frame 100. The frame 100 is hollow inside to form a compartment 110. A trash bin 200 is placed in the compartment 110. An opening 120 is provided on a side of the compartment 110 away from the front of the vehicle. A tailgate 300 is installed at the opening 120 of the compartment 110, and the compartment 110 can be opened and closed by the tailgate 300.

[0035] In some embodiments, when the back door 300 is in a closed state, the back door 300 has a first side wall 310 facing the outside of the vehicle compartment 110, and the trash bin 200 has a second side wall 210 facing the outside of the vehicle compartment 110. That is, when the back door 300 is in a closed state, the first side wall 310 and the second side wall 210 can be directly seen from the side of the frame 100 away from the front of the vehicle, that is, the first side wall 310 and the second side wall 210 are directly exposed to the outside of the vehicle compartment 110, wherein the second side wall 210 of the trash bin 200 is below the first side wall 310 of the back door 300.

[0036] In some embodiments, the first end of the back door 300 away from the trash bin 200 is rotatably connected to the frame 100. Specifically, the first end of the back door 300 is mounted on the frame 100 through three hinges 400, and the hinges 400 can better realize the rotation between the first end of the back door 300 and the frame 100, so that the back door 300 can be opened and closed by rotating the first end.

[0037] In some embodiments, a first link 111 and a second link 112 are further provided between the trash bin 200 and the frame 100, wherein the first end of the first link 111 is rotatably connected in the carriage 110, the second end of the first link 111 is rotatably connected to the trash bin 200, the first end of the second link 112 is rotatably connected in the carriage 110, and the second end of the second link 112 is rotatably connected to the trash bin 200. When the tailgate 300 is in an open state, the trash bin 200 can be pulled, and the trash bin 200 can be pulled out of the vehicle compartment 110 by the rotation of the two ends of the first link 111 and the second link 112; similarly, when a reverse force is applied to the trash bin 200, the two ends of the first link 111 and the second link 112 will rotate in the opposite direction, and the trash bin 200 can be pushed into the vehicle compartment 110; through the arrangement of the first link 111 and the second link 112, on the one hand, the connection between the trash bin 200 and the vehicle frame 100 is realized, and on the other hand, it is also convenient for the staff to move the trash bin 200, making it easy to use.

[0038] In some embodiments, a driving mechanism 600 is provided in the carriage 110, and the driving mechanism 600 can be specifically connected to the back door 300 and / or the trash bin 200. When the driving mechanism 600 is connected to the back door 300, the driving mechanism 600 is used to drive the back door 300, and when the driving mechanism 600 is working, the back door 300 can be opened or closed; when the driving mechanism 600 is connected to the trash bin 200, the driving mechanism 600 is used to drive the trash bin 200, and when the driving mechanism 600 is working, the trash bin 200 can be moved out of the carriage 110 or moved into the carriage 110 from the outside; when the driving mechanism 600 is connected to both the back door 300 and the trash bin 200, the back door 300 and the trash bin 200 can be driven respectively by the driving mechanism 600, which is convenient for use.

[0039] Furthermore, the driving mechanism 600 may include a motor, a cylinder, or an electric telescopic rod, etc., as long as it can drive the back door 300 or the trash bin 200.

[0040] Furthermore, a control button may be provided at the front of the vehicle to control the operation of the driving mechanism 600 , so that the driving mechanism 600 can be used to drive the movement of the back door 300 or the trash bin 200 .

[0041] In some embodiments, at least one limiting member 500 is provided between the tailgate 300 and the trash bin 200. When the tailgate 300 is in a closed state, the limiting member 500 can limit the tailgate 300 so that the tailgate 300 can be stably attached to the opening 120 of the vehicle compartment 110, thereby preventing the tailgate 300 from opening.

[0042] By setting the limiting member 500, the stability of the tailgate 300 in the closed state can be better improved. Even if the vehicle is in motion or passing through a bumpy road, the tailgate 300 will not shake significantly. Compared with the method of magnetic adsorption, the stability of limiting the tailgate 300 directly through the hardware structure is higher. Under the limiting action of the limiting member 500, the tailgate 300 can be directly blocked without failure, thereby preventing the tailgate 300 from opening.

[0043] In some embodiments, the limiting member 500 has a mounting portion 510 and a limiting portion 520. In this embodiment, the mounting portion 510 and the limiting portion 520 are arranged perpendicular to each other, so that the limiting member 500 is L-shaped; specifically, the mounting portion 510 is fixedly connected to the trash can 200, and when the back door 300 is in a closed state, the limiting portion 520 is located on the side of the first side wall 310 facing the outside of the vehicle compartment 110.

[0044] It can be understood that when the tailgate 300 is in the closed state, since the limiting portion 520 of the limiting member 500 fixedly connected to the trash bin 200 is located on the side of the first side wall 310 facing the outside of the vehicle compartment 110, in this embodiment, the limiting portion 520 is located at the second end of the tailgate 300. Therefore, the second end of the tailgate 300 can be blocked by the limiting portion 520, so that the second end of the tailgate 300 cannot move toward the outside of the vehicle compartment 110, thereby realizing the limiting of the tailgate 300 by the limiting member 500 through the limiting portion 520, thereby improving the stability of the tailgate 300 in the closed state.

[0045] It should be noted that when the back door 300 is opened from closed to open, the back door 300 is opened and the trash bin 200 is also moved toward the outside of the compartment 110. During the movement of the back door 300 and the trash bin 200, the second end of the back door 300 and the limiting portion 520 can be separated, thereby realizing the opening of the back door 300 and the movement of the trash bin 200. When the back door 300 is opened to closed, the back door 300 is closed and the trash bin 200 is also moved toward the inside of the compartment 110. When the back door 300 is completely attached to the opening 120 of the compartment 110, the trash bin 200 is opened. The trash bin 200 is also completely moved into the compartment 110. It should be noted that the process of the trash bin 200 being completely moved into the compartment 110 is slower than the process of the tailgate 300 being completely closed, so that the limiting portion 520 of the limiting member 500 fixed on the trash bin 200 is farther away from the compartment 110 than the second end of the tailgate 300. Therefore, when the tailgate 300 is completely closed, the limiting portion 520 can be located on the side of the second end of the tailgate 300 facing outside the compartment 110, so that the second end of the tailgate 300 can be blocked and limited, thereby realizing the self-locking of the tailgate 300 and improving the stability of the tailgate 300 in the closed state.

[0046] In some embodiments, a guide portion 521 is further provided on the limiting portion 520, and the guide portion 521 is specifically provided at a position of the limiting portion 520 away from the mounting portion 510. In this embodiment, the guide portion 521 is an arc-shaped plate and the arc-shaped plate is bent and extended toward the outside of the vehicle compartment 110; the guide portion 521 can guide or direct the movement of the tailgate 300. During the closing process of the tailgate 300, the second end of the tailgate 300 will basically move along the bending direction of the arc-shaped outer wall of the guide portion 521, thereby enabling the tailgate 300 to move to the side of the limiting portion 520 facing the vehicle compartment 110, so that the limiting portion 520 can limit the tailgate 300 and improve the stability of the tailgate 300.

[0047] In some embodiments, a plurality of first positioning holes 511 are provided on the mounting portion 510 of the limiting member 500, and a second positioning hole (not shown in the figure) matching the first positioning hole 511 is provided on the trash bin 200; when installing the limiting member 500 on the trash bin 200, first align the first positioning hole 511 on the limiting portion 520 with the second positioning hole on the trash bin 200, and then extend the bolt 512 into the first positioning hole 511 and the second positioning hole, so as to realize the fixed connection between the limiting member 500 and the trash bin 200 through the mounting portion 510.

[0048] Specifically, in the present embodiment, a third side wall 220 is provided on the side of the second side wall 210 toward the inside of the vehicle compartment 110, and the third side wall 220 is located at one end of the second side wall 210 close to the first side wall 310, the third side wall 220 is disposed perpendicular to the second side wall 210, and the first positioning hole 511 is disposed on the third side wall 220; when the mounting portion 510 of the L-shaped limiting member 500 is fixedly installed on the third side wall 220, a portion of the mounting portion 510 can extend out of the vehicle compartment 110 through the gap between the first side wall 310 and the second side wall 210, thereby enabling the limiting portion 520 of the limiting member 500 to be located on the side of the first side wall 310 toward the outside of the vehicle compartment 110, thereby effectively limiting the second end of the tailgate 300.

[0049] It can be understood that, in some embodiments, the limit member 500 can also be fixedly installed on the tailgate 300, so that the limit portion 520 is located on the side of the second side wall 210 facing the interior of the vehicle compartment 110. Through the obstruction between the limit portion 520 and the second side wall 210, the limit member 500 can also achieve a limiting effect on the second end of the tailgate 300, thereby preventing the tailgate 300 from shaking and even opening.

[0050] In some embodiments, at least one reinforcement is provided on the tailgate 300, and the provision of the reinforcement can improve the structural strength of the tailgate 300. While the structural strength of the tailgate 300 is improved, the stability and safety of the tailgate 300 in the closed state can also be improved accordingly.

[0051] It is understandable that the provision of the reinforcement increases the weight of the tailgate 300 accordingly, further requiring a greater driving force for the tailgate 300 to shake and open, thereby making the tailgate 300 more stable in the closed state.

[0052] Furthermore, a reinforcement member may be provided at a position of the back door 300 corresponding to the stopper 500 to improve the structural strength of the back door 300 where it is blocked by the stopper 500 , thereby improving stability and safety.

[0053] In some embodiments, the reinforcement includes two ridges 320, and both ridges 320 are located on the side of the first side wall 310 facing the outside of the vehicle compartment 110. However, in actual application, the ridges 320 are arranged on the side of the first side wall 310 facing the inside of the vehicle compartment 110, which can also play a role in improving the structural strength of the tailgate 300. Therefore, as long as the ridges 320 are arranged on the tailgate 300, there is no special limitation on this.

[0054] In some embodiments, the reinforcement member includes a reinforcement plate (not shown in the figure), which can be fixed on the tailgate 300 by bolts 512, so that the reinforcement plate and the tailgate 300 form an integrated structure, thereby improving the structural strength of the tailgate 300.

[0055] In a second aspect, a vehicle is provided in this embodiment, comprising the self-locking tailgate described above. Therefore, the vehicle in this embodiment can have the corresponding technical effects and advantages described above.

[0056] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
