Description

Technical Field

[0001] This utility model relates to the field of pickup truck manufacturing technology, and in particular to an electrically openable and electrically closed pickup truck cargo tailgate. Background Technology

[0002] Most pickup trucks currently feature manually operated tailgates, while electrically operated tailgates are more commonly found in SUVs and MPVs. This means that opening and closing the tailgates on pickup trucks still largely relies on manual operation, which is time-consuming and labor-intensive. Furthermore, in existing SUVs and MPVs, the electrically operated tailgates are controlled automatically from the driver's cab or remotely via the key fob. However, closing the tailgate requires the driver to get out of the vehicle, walk around to the rear, and manually press the close button on the bottom edge of the tailgate, making the process cumbersome. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an electrically openable and electrically closed tailgate for pickup truck cargo boxes.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution: The electrically operated pickup truck cargo tailgate of this utility model includes a door hinged to the rear end of the pickup truck cargo box. Inside the door is a power assembly for driving it to tilt upwards or downwards. The power assembly includes a power source and a pair of synchronously rotating drive rods driven by the power source. The axes of the two drive rods are aligned with the hinge shaft axes of the left and right sides of the door that are hinged to the pickup truck cargo box. The distal ends of the two drive rods are respectively fixed to the left and right side panels of the door through connectors.

[0005] Furthermore, the power source includes a fixed frame, a drive motor, and a worm gear reducer. The fixed frame is installed in the interlayer cavity inside the door. The drive motor and the worm gear reducer are mounted on the fixed frame. The worm gear reducer has a power input end that is drively connected to the working shaft of the drive motor, and a pair of power output ends for inserting the drive rod. Using a worm gear reducer to drive and connect the drive motor and the drive rod ensures a high speed ratio reduction while possessing excellent self-locking properties, effectively preventing reverse power transmission and achieving safe braking.

[0006] Furthermore, torsion springs are fitted on the hinge shafts on both sides of the door. The torsion springs can provide a reverse force when the door flips down to prevent the door from falling too fast.

[0007] The advantages of this invention lie in its simple and lightweight structure, and its ease of installation and operation. It can easily achieve electric opening and closing of the rear cargo door of a pickup truck. The opening and closing operations can be completed simultaneously from the driver's cab or using a remote control switch, making operation simpler, faster, and more labor-saving. This improves the convenience of opening and closing the rear cargo door of the pickup truck, enhances the recognizability of the final produced pickup truck product, and improves brand awareness and competitiveness.

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] Figure 2 yes Figure 1 The exploded diagram. Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 , 2 As shown, the electrically openable and electrically closed pickup truck cargo tailgate of this utility model includes a hollow structure door 1 formed by an inner wall panel, an outer wall panel, a left side panel, a right side panel, a top side panel, and a bottom side panel. The left and right side panels of the door 1 are hinged to the rear end of the pickup truck cargo box near the lower edge via hinge shafts to form a tailgate that can cover the pickup truck cargo box. The door 1 has a cargo box closing position that rotates upward around the hinge shaft to a vertical position and a cargo box opening position that rotates downward around the hinge shaft to a horizontal position.

[0012] A power assembly for driving the door 1 to tilt upwards or downwards is provided inside the door 1. The power assembly is located in the cavity inside the door 1, which can avoid occupying extra space inside the vehicle and improve the integrity and completeness of the door 1. The power assembly includes a power source 2 and a pair of drive rods 3 driven by the power source 2 to rotate synchronously. The axes of the two drive rods 3 are aligned and are aligned with the axes of the hinge shafts on the left and right sides of the door 1 that are hinged to the pickup truck cargo box. The far ends of the two drive rods 3 are respectively fixed to the inner sides of the left and right side panels of the door 1 through connectors 4.

[0013] Specifically, the power source 2 includes a fixed frame 2.1, a drive motor 2.2, and a worm gear reducer 2.3. The fixed frame 2.1 is installed in the interlayer cavity inside the door 1. The drive motor 2.2 and the worm gear reducer 2.3 are mounted on the fixed frame 2.1. The worm gear reducer 2.3 has a power input end that is connected to the working shaft of the drive motor 2.2, and a pair of power output ends for inserting the drive rod 3. The worm gear reducer 2.3 is used to form the transmission connection between the drive motor 2.2 and the drive rod 3, which can ensure a high speed ratio reduction while having excellent self-locking performance, effectively preventing the reverse transmission of power and realizing the safe braking of the door 1.

[0014] In addition, to further improve the stability of the door 1 when it rotates and opens, a torsion spring 5 should be installed on the hinge shafts on the left and right sides of the door 1 respectively. The torsional direction of the two torsion springs 5 ​​is the same, which can provide a reverse force when the door 1 is flipped down to open, so as to prevent the door 1 from falling too fast and hitting the driver or the vehicle body.

[0015] In actual operation, simply control the drive motor 2.2 to rotate forward to open the cargo box 1, or control the drive motor 2.2 to rotate in reverse to close the cargo box 1. Of course, the control button for the drive motor 2.2 can be located in the driver's cab or on a remote control switch. This way, the driver and passengers can easily open or close the pickup truck cargo box electrically from the driver's cab by operating the control button or the remote control switch without getting out of the vehicle. This makes the operation simpler, faster, and saves time and effort, improves the convenience of opening and closing the cargo box 1 at the rear of the pickup truck cargo box, increases the recognizability of the final produced pickup truck product, and enhances brand awareness and competitiveness.

[0016] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
