Description

Technical Field

[0001] This utility model relates to the field of automobile tailgate technology, and in particular to a double-opening tailgate. Background Technology

[0002] For family travel needs, larger vehicles offer more spacious seating and storage, meeting the demands of family trips. For business travelers and long-distance journeys, larger vehicles provide a more comfortable ride and more storage space, suitable for extended journeys and carrying large amounts of luggage. For consumers seeking a personalized driving experience and luxury, larger vehicles offer more customization options and premium features. Based on these demands, the market is seeing an increasing number of larger vehicles. As the tailgate is the part that passengers need to open and close to access their luggage, its size naturally increases with the size of the vehicle. However, the space required for opening and closing the tailgate also increases; in congested parking lots, opening a large tailgate often results in it hitting vehicles or walls behind, causing inconvenience in accessing luggage. When parking off-road or on rough terrain, the tailgate may not be able to open fully due to the tilt of the ground.

[0003] Patent CN202510086980.X discloses a tailgate system and vehicle. This solution includes a tailgate, hinge assembly, glass, tailgate lock assembly, sealing assembly, and lifting assembly. The tailgate system has three modes: glass opening mode, side opening mode, and rear-flip opening mode. When the tailgate is against a wall or in a confined space, opening is restricted. In this case, the glass opening mode can be switched to, allowing the user to retrieve items by lowering the glass. In height-restricted areas such as underground parking garages, the side opening mode or rear-flip opening mode can be switched to, allowing the user to access the trunk and move goods. However, configuring three independent hinge mechanisms results in a complex structure and increased overall weight.

[0004] Therefore, existing technologies have drawbacks such as complex structure, high manufacturing cost, and low reliability in addressing the issue of tailgate opening in multiple limited scenarios. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the existing technology mentioned above and provide a double-opening tailgate with multiple spatial adaptability; lightweight, low cost and high reliability.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] This utility model proposes a dual-opening tailgate with a smaller opening door. The smaller door requires less space to open, preventing collisions with vehicles or walls when parking. Opening the smaller door when parking on slopes or uneven surfaces also reduces the risk of items rolling out. Its unique opening mechanism enhances vehicle brand recognition and attracts specific consumer groups. It overcomes the limitations of traditional large tailgates that are either fully open or fully closed, offering advantages in space utilization, scenario adaptability, and user experience, making it particularly suitable for car owners who prioritize multi-functionality, outdoor activities, or urban commuting needs.

[0008] This utility model provides a double-opening tailgate, including:

[0009] The tailgate is hinged to the vehicle body.

[0010] The tailgate small door is connected to the tailgate large door via a shared hinge;

[0011] The shared hinge includes two hinge structures, with the first hinge connected to the main tailgate and the second hinge connected to the small tailgate.

[0012] The sealing strip is snapped onto the tailgate door and achieves a seal between the tailgate door and the tailgate hatch by compression through a bubble tube.

[0013] Small door lock assembly, including a small door lock installed on the tailgate small door and a small door lock ring installed on the tailgate large door, or installed in reverse;

[0014] The small door support rod is connected at the upper end to the tailgate door or the vehicle body, and at the lower end to the tailgate small door, and is used to keep the tailgate small door open.

[0015] Furthermore, the tailgate hatch is made of composite material to meet the requirements for lightweight design.

[0016] Furthermore, the shared hinge is a coaxial structure, allowing the tailgate main door and tailgate side door to open and close relatively independently.

[0017] Furthermore, this also includes the rear windshield glass, which is bonded to the tailgate door using silicone sealant.

[0018] Furthermore, the small door support rod is provided in two parts, which are respectively installed on both sides of the tailgate.

[0019] Furthermore, the first hinge is connected to the tailgate main door by a first bolt, and the second hinge is connected to the tailgate side door by a second bolt.

[0020] Furthermore, the upper end of the small door support rod is connected to the tailgate main door via a fourth bolt, and the lower end is connected to the tailgate small door via a third bolt.

[0021] Furthermore, the space occupied when the tailgate small door is opened is less than the space required for the tailgate large door to be fully opened.

[0022] Furthermore, the sealing strip is snapped into place around the circumference of the tailgate.

[0023] Furthermore, the tailgate is connected to the vehicle body via hinges.

[0024] The assembly process is as follows:

[0025] First, connect the common hinge to the tailgate door using a tooling and bolts; then connect the tailgate door with the hinge to the vehicle body; next, install the sealing strip on the tailgate door using a snap-fit ​​method; and finally, install the small door lock ring on the tailgate door using bolts.

[0026] The rear windshield glass is bonded to the tailgate small door with glass glue; then the assembled tailgate small door is connected to the common hinge using a tool; then the small door lock is assembled to the tailgate small door with bolts; finally, the small door support rods are assembled to the tailgate large and small doors respectively to complete the assembly.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] (1) It has multiple spatial adaptability. Applicability to narrow environments: In crowded parking lots or narrow spaces, the opening space of the small door is smaller than that of a traditional tailgate, avoiding the risk of collision with vehicles / walls behind. Adaptability to complex terrain: When parking on a slope, the small door can be opened to reduce the risk of items rolling off; basic functionality is still guaranteed even on rough terrain. Adjustable gap position: The gap position between the small door and the main door can be optimized according to ergonomics to meet the needs of users of different heights and in special scenarios.

[0029] (2) Lightweight and low cost. The shared hinge enables double opening, resulting in a compact structure and high reliability. The small door uses composite materials, which are lighter than an all-metal structure, meeting the lightweight requirements of large-size tailgates. Attached Figure Description
