Description

Technical Field

[0001] The invention particularly relates to a vehicle side cargo door system based on composite materials. Background Art

[0002] A vehicle side pickup door usually refers to a door on the side of a vehicle used for picking up or loading goods, and is widely used in commercial vehicles such as trucks, delivery trucks, vans, etc. This type of door is designed to provide convenient side passage and facilitate cargo loading and unloading, and is particularly suitable for transportation tasks that require frequent side operations.

[0003] During use, the existing car side pickup door has an outward-opening door panel that is mostly one-piece. When it is rotated outward to open, it occupies a large external length space and cannot maximize the door opening space for people to pick up goods. In addition, the door panel is mostly made of metal, which is heavy and has a high production cost. For this reason, we propose a car side pickup door system based on composite materials. Summary of the invention

[0004] The object of the present invention is to provide a vehicle side cargo door system based on composite materials to solve the problems raised in the above background technology.

[0037] Preferably, a gas spring 10 is rotatably connected to the upper end of the inner wall of the door frame 1, and the other end of the gas spring 10 cooperates with the inner panel 5 to facilitate supporting the first door panel 2 after it is opened.

[0038] Preferably, the lock assembly 7 includes a pull rope 701, a connecting strip 702, a mounting frame 703, a slide groove 705, a return spring 706 and a lock tongue 707. The mounting frame 703 is detachably mounted on the upper edge of the second door panel 3, and the inner end of the mounting frame 703 has a slide groove 705. The lock tongue 707 is slidably mounted on the inner side of the slide groove 705, and one end of the lock tongue 707 has a connecting strip 702. The return spring 706 is sleeved on the outer surface of the connecting strip 702, and one end of the return spring 706 is in conflict with the lock tongue 707. One end of the connecting strip 702 is provided with a pull rope 701 that cooperates with the rotating handle 9, so that the second door panel 3 can be unlocked by pulling the pull rope 701, thereby facilitating opening.

[0039] Preferably, the lock assembly 7 also includes a limit frame 704, which is detachably mounted on the inner wall of the door frame 1, and a slot matching the lock tongue 707 is provided on one side of the limit frame 704, so as to quickly match the lock tongue 707 with the slot to complete the locking of the second door panel 3.

[0046] The working principle and use process of the present invention are as follows: when in use, the handle 4 is pulled toward the side away from the first door panel 2, at which time the handle 4 drives the pull cords 701 at both ends of the first lock body 6 to move, and the pull cords 701 drive the lock tongue 707 to move through the connecting strip 702, so that the lock tongue 707 withdraws from the slot on one side of the limiting frame 704, and at this time the first door panel 2 can be flipped upward to 93°, and the first door panel 2 is supported by the handle 4, and then the rotating handle 9 is turned, and the rotating handle 9 drives the pull cords 701 at both ends of the second lock body 8 to move, and similarly, the other lock tongues 707 can be released from the other slots. , and then the second door panel 3 can be flipped downward to 178° to maximize the cargo picking space. The first door panel 2 and the second door panel 3 are both made of PP (polypropylene) + EPDM (ethylene propylene rubber) + T30 (polypropylene homopolymer) materials, and the inner panel 5 is made of high-temperature resistant SMC (sheet molding compound) material, which is then bonded with polyurethane two-component adhesive to form a cavity. A sheet metal bracket will be assembled inside before bonding to avoid the traditional door panels that are welded with aluminum plates and aluminum tubes, which are heavy and costly. The present device can have both good lightweight effects and low manufacturing costs.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
