[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0024] According to an embodiment of this utility model, a vehicle body structure is provided; please refer to [link / reference]. Figures 1 to 2 The vehicle includes a vehicle frame 1, on which a front side door 2 and a rear side door 3 forming a double-door structure are provided. The front side door 2 and the rear side door 3 are located on the same side of the vehicle frame 1, and there is a portion of the vehicle frame between them. A rear door 4 is provided at the rear end of the vehicle frame 1. The front side door 2, the rear side door 3 and the rear door 4 are respectively connected to the vehicle frame 1 through locking mechanisms.

[0025] Compared to existing technologies that use sliding doors, adopting a double-door structure for the front side door 2 and the rear side door 3 not only eliminates the hassle of installing sliding tracks but also reduces the number of positioning and locking points required. The advantage of this design lies in its simpler and clearer structure, involving relatively fewer mechanical parts, thereby effectively reducing maintenance costs, manufacturing complexity, and overall cost.

[0026] Furthermore, the front side door 2, the rear side door 3, and the rear door 4 are hinged to the vehicle body frame 1. Particularly noteworthy is the hinged connection of the rear side door 3 to the vehicle body frame 1. Specifically, the middle of the rear side door 3 is hinged to the vehicle body frame 1, cleverly avoiding the fatigue impact problem between the rear side door and the vehicle body frame that may occur in traditional designs. This not only prevents deformation of the rear side door due to long-term use but also eliminates the possibility of the door getting stuck, ensuring smooth and durable door opening and closing operations. This improves the overall quality of the vehicle and provides users with a safer and more convenient user experience.

[0027] Furthermore, the front side door 2 and the rear side door 3 are not in direct contact, but are separated by a portion of the body frame. This allows for better installation of sealing strips, improving the sealing effect when the doors are closed and reducing the possibility of air or water leakage. At the same time, retaining a portion of the body frame between the front side door 2 and the rear side door 3 can significantly enhance the overall rigidity of the body structure.

[0028] Furthermore, the vehicle frame 1 is made of high-strength steel to enhance the strength and rigidity of the overall structure.

[0029] Furthermore, one side of the vehicle frame 1 is provided with a front side door 2 and a rear side door 3 that form a double-door structure. Taking the double-door structure on the right side of the vehicle frame 1 as an example, the vehicle frame 1 is provided with a left front door, a right front door and a rear side door, and the right front door and the rear side door form a double-door structure.

[0030] Furthermore, the vehicle body frame 1 is provided with a front side door 2 and a rear side door 3 on both sides, forming a double-door structure. Specifically, the vehicle body frame 1 is provided with a left front door, a left rear door, a right front door, and a rear side door. The left front door and the left rear door form a double-door structure, and the right front door and the rear side door form a double-door structure.

[0031] Furthermore, given that MPVs, microvans, motorhomes, vans, SUVs, and light commercial vehicles typically have relatively high bodies, in order to minimize the weight of the rear side door 3 without compromising functionality, the bottom of the rear side door 3 extends to the chassis of the vehicle frame 1, while its top is set lower than the roof height of the vehicle frame 1. Specifically, this structural design intentionally leaves a certain gap between the rear side door 3 and the roof, satisfying both functional requirements and achieving the goal of lightweight design.

[0032] Furthermore, the rear door 4 is configured as a double-opening, lift-up, or side-opening type.

[0033] In the vehicle body structure of this embodiment, please refer to Figures 1 to 2 The locking mechanism includes a lock body and a latch. The lock body is respectively disposed on the front side door 2, the rear side door 3 and the rear door 4, and the latch is disposed on the vehicle body frame 1 corresponding to the lock body.

[0034] It should be noted that the combined use of the lock body and the latch ensures that the car door is securely closed, preventing the door from opening accidentally while the vehicle is in motion, thereby ensuring the safety of the passengers inside the vehicle.

[0035] Furthermore, the lock body is equipped with automatic locking or electronic control functions, making it simple and quick to close the car door.

[0036] Furthermore, sealing strips are installed between the front side door 2, the rear side door 3, and the rear door 4 and the vehicle body frame 1. Additionally, a lock body is installed in the middle of each door (including the front side door 2, the rear side door 3, and the rear door 4). Positioning the lock body in the middle of the door allows for a more even distribution of force when the door is closed between the door and the vehicle body frame 1, helping to reduce the risk of door deformation due to uneven force distribution and enhancing the overall stability of the connection point between the door and the vehicle body frame 1. Simultaneously, the design of the lock body in the middle ensures better uniform compression of the sealing strip around the door, thus providing a better sealing effect.

[0037] In the vehicle body structure of this embodiment, please refer to Figures 1 to 3 An inner handle 10 is provided on the inner side of the rear side door 3. The top and bottom of the inner handle 10 are respectively set as arc-shaped structures that adapt to the curvature of the inner side of the rear side door to improve the fit of the assembly.

[0038] Furthermore, the top and bottom widths of the inner handle 10 are greater than its middle width to improve assembly stability. At the same time, the top and bottom of the inner handle 10 are provided with mounting holes, through which screws pass and are embedded inside the side rear door 3.

[0039] Furthermore, the inner handle 10 is located on the edge of the rear side door 3 near the front side door 2, which makes full use of the space inside the rear side door 3, avoids interference with other functional areas, and conforms to ergonomics, improving the ease of operation. The inner handle 10 is set in a vertical direction, which conforms to the gripping habits of most users, making the opening and closing of the door more convenient. The middle of the inner handle 10 is provided with a recessed relief groove 11 that moves away from the front side door 2, providing more space for the user's gripping work and avoiding the risk of fingers being pinched due to the inner handle 10 being too close to the edge of the rear side door 3.

[0040] In the vehicle body structure of this embodiment, please refer to Figures 1 to 3 The inner handle 10 is equipped with a lock body switch 12 that is connected to the lock body on the rear side door 3. The inner handle 10 and the lock body switch 12 are integrated, allowing users to directly control the locking and unlocking status of the door by operating the lock body switch 12, making the opening and locking operations simpler and faster.

[0041] Specifically, the top of the inner handle 10 is provided with a receiving groove, and the lock body switch 12 is located inside the receiving groove. The door can be unlocked and / or locked by moving the lock body switch 12.

[0042] In the vehicle body structure of this embodiment, please refer to Figures 1 to 2 A foot pedal 7 is provided on the chassis of the vehicle body frame 1, and the foot pedal 7 is located below the side rear door 3.

[0043] Furthermore, the connection structure between the foot pedal 7 and the chassis can be set to telescopic. At the same time, the foot pedal 7 can be set to a hollow structure, which can reduce the overall weight and prevent dust accumulation.
