[0029] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this utility model, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0031] like Figures 1-10 As shown, the front passage door assembly of the car trunk of the present invention is fixed to the body sheet metal by screws, such as Figure 3 The vehicle trunk front passage door assembly is composed of a trunk front passage door 1, a fixing bracket 2, a blocking cover 3, and a motor 4.

[0032] The fixing bracket 2 is secured to the vehicle body sheet metal via six screws. Specifically, the fixing bracket 2 is secured to the vehicle body. Specifically, a screw seat is provided at each of the four corners of the fixing bracket 2, each secured to the vehicle body sheet metal via a screw. A screw seat is also provided on the lower edge of the fixing bracket 2, near the motor 4, for securing to the vehicle body sheet metal via a single screw. A screw seat is also provided in the middle of the upper edge of the fixing bracket 2, away from the trunk's front access door 1, for securing to the vehicle body sheet metal via a single screw.

[0033] A sliding groove is respectively provided on the upper and lower sealing edges of the fixing bracket 2 .

[0034] The blocking cover 3 is provided with a screw seat, and the upper and lower left side sealing edges of the fixed bracket 2 are each provided with a screw to be screwed to the blocking cover 3. In the present utility model, the blocking cover 3 is provided to fix and restrict the sliding out of the trunk front passage door 1. Specifically, the trunk front passage door 1 is slid from the side into the upper and lower sliding grooves of the fixed bracket 2. The protruding flanges at the upper and lower ends of the trunk front passage door 1 can slide with the sliding grooves and move left and right along the sliding grooves under the action of external force. The blocking cover 3 is then installed to prevent the trunk front passage door 1 from sliding out of the sliding groove through the left side sealing edge of the fixed bracket 2.

[0035] A plurality of ridges are provided on the right side sealing edge of the fixing bracket 2, three in this embodiment, for limiting the position of the front passage door 1 of the luggage compartment when it slides to the right.

[0036] A limiting bracket is provided on the left and right sides of the motor 4 , respectively. The limiting brackets are connected to the fixing bracket 2 by two screws passing through the limiting brackets to fix the motor 4 on the fixing bracket 2 .

[0037] A rack is provided below the trunk front passage door 1, capable of meshing with a gear mounted on the end of the output shaft of the motor 4. The occupants in the cab activate the motor via a switch. The gear on the motor output shaft, through the meshing transmission of the rack and pinion, drives the trunk front passage door 1 to slide left and right along the upper and lower grooves of the fixed bracket 2, thereby opening and closing the trunk front passage door 1. Specifically, a wiring harness is used to connect the switch to the motor to control the motor. The forward and reverse rotation of the motor is achieved by reversing the positive and negative poles of the power supply, allowing the trunk front passage door 1 to move left and right along the upper and lower grooves of the fixed bracket 2, thereby opening and closing the trunk front passage door 1.
