Description

Technical Field

[0001] This utility model relates to the field of unmanned delivery vehicle technology, and in particular to a frame for an unmanned delivery vehicle. Background Technology

[0002] With the rapid development of e-commerce and logistics, unmanned delivery vehicles are increasingly being used as a solution for "last-mile" delivery. The vehicle frame, as a key load-bearing structure of unmanned delivery vehicles, directly affects the stability, safety, load-bearing capacity, and internal space layout of the entire vehicle.

[0003] Existing unmanned delivery vehicle frames are mostly modified from traditional vehicle chassis structures, which have the following problems: First, the structure lacks rigidity and is prone to deformation when driving on complex road conditions or being hit by a collision, affecting vehicle stability and the safety of internal precision equipment; second, the functional layout is unreasonable, and the layout of key parts such as the battery compartment, wheel hubs, and front assembly area has not been optimized, resulting in low space utilization or an unstable center of gravity; third, the front frame is mostly a simple three-dimensional frame with weak impact resistance, making it difficult to effectively absorb energy and protect core components in the event of a collision.

[0004] Therefore, there is an urgent need for a special chassis for unmanned delivery vehicles that is structurally stable, rationally laid out, highly rigid, and lightweight. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a frame for an unmanned delivery vehicle, the specific technical solution of which is as follows: A frame for an unmanned delivery vehicle includes a base frame and a front frame, wherein the front frame is fixedly mounted on one side of the base frame. Its innovation lies in: The base frame includes an outer frame, battery partition brackets, front wheel rims, rear wheel rims, and a front-end mounting bracket. The outer frame is rectangular, forming the basic outline of the vehicle frame. Two battery partition brackets are parallel and perpendicular to each other on the lower surface of the outer frame, forming a neat battery compartment for the centralized and safe placement of the vehicle batteries. The front-end mounting bracket is horizontally positioned on one side of the outer frame for precise positioning and installation of the front-end frame. The front and rear wheel rims are fixedly mounted on the lower surface of the outer frame, located on either side of the battery partition brackets, with the front wheel rims positioned closer to the front-end frame. This layout helps optimize the vehicle's center of gravity distribution.

[0006] The front frame includes a lower front frame, a middle front frame, a top front frame, a first connecting rod, and a second connecting rod. The lower front frame, middle front frame, and top front frame are arranged parallel to each other from bottom to top, forming a stable tower structure. The first connecting rod is fixedly connected to the lower front frame and the middle front frame at its upper and lower ends, respectively, and the second connecting rod is fixedly connected to the middle front frame and the top front frame at its upper and lower ends, respectively. These connecting rods greatly enhance the longitudinal rigidity and torsional resistance of the front frame. The lower front frame is constructed as a polygonal frame to improve structural stability.

[0007] Furthermore, a preferred embodiment of the lower frame of the vehicle front is a hexagonal structure, including a long side, a short side, two side edges, and two inclined sides. The long side is parallel to the short side, the two side edges are vertically fixed to the two ends of the long side, and one end of the two inclined sides connects to the two sides of the short side, while the other end connects to the two side edges respectively. This hexagonal structure, by introducing the inclined sides, effectively disperses the impact force throughout the entire frame, significantly improving impact resistance and stability.

[0008] Furthermore, to enhance the rigidity of the base frame, vertically downward outer frame support frames are provided on the lower ends of both sides of the outer frame, and the battery partition frame is fixedly connected to the outer frame support frames through the outer frame connecting frame, forming a stable triangular support system.

[0009] Furthermore, a front crossbeam extends outward from the side of the outer frame closest to the front frame, and a trim panel is installed on its outer side. The front crossbeam not only increases the structural strength of the front of the vehicle, but also absorbs and disperses impact energy during a collision.

[0010] Furthermore, a bumper mounting bracket is provided at the lower end of the front crossbeam for mounting the bumper and providing primary protection.

[0011] Furthermore, the outer wall of the base frame is provided with several side trim panel connectors to facilitate the installation and fixation of the vehicle shell.

[0012] Furthermore, decorative panel fittings are also provided on the outer walls of the first and second connecting rods, achieving a unity of structural function and aesthetic assembly.

[0013] Furthermore, the entire base frame is preferably made of high-strength aluminum alloy, achieving a perfect combination of lightweight and high strength.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Stable structure and high rigidity: The battery partition frame, outer frame support frame, and outer frame connecting frame work together to form a highly rigid base frame. The multi-layered parallel frame and vertical connecting rod design of the front frame form a stable spatial truss structure, significantly improving the overall torsional and impact resistance.

[0015] The layout is rational and space utilization is high: the battery compartment is centrally and neatly arranged between two battery partition racks, with a compact layout that facilitates the installation and maintenance of the battery pack. The front and rear wheel rims are located on both sides of the battery compartment, optimizing the vehicle's center of gravity and improving driving stability.

[0016] High safety: The unique hexagonal lower frame structure at the front and the design of the front crossbeam can effectively absorb and disperse collision energy from the front, providing better protection for critical components such as electronic equipment and batteries inside the vehicle.

[0017] High integration and easy assembly: The chassis integrates various mounting structures such as trim panel fittings and bumper mounting brackets, which facilitates the quick and accurate installation of vehicle shells, bumpers and other accessories, improving production efficiency.

[0018] Lightweight: The use of lightweight materials such as high-strength aluminum alloy effectively reduces the weight of the vehicle frame while ensuring structural strength, which helps to extend the driving range of the unmanned delivery vehicle. Attached Figure Description

[0028] like Figures 1 to 3 As shown, a frame for an unmanned delivery vehicle includes a base frame 1 and a front frame 2, with the front frame 2 fixedly mounted on one side of the base frame 1. The base frame 1 includes an outer frame 11, a battery partition frame 12, a front wheel rim 13, a rear wheel rim 14, and a front mounting frame 15. The outer frame 11 is rectangular, forming the basic outline of the frame. Two battery partition frames 12 are parallel and perpendicular to each other on the lower surface of the outer frame 11, forming a regular battery compartment for the centralized and safe placement of the vehicle's batteries. The front mounting frame 15 is horizontally positioned on one side of the outer frame 11 for precise positioning and installation of the front frame 2. The front wheel rim 13 and rear wheel rim 14 are fixedly mounted on the lower surface of the outer frame 11 and located on either side of the battery partition frame 12, with the front wheel rim 13 positioned close to the front frame 2. This layout helps optimize the vehicle's center of gravity distribution.

[0029] The front frame 2 includes a lower front frame 21, a middle front frame 22, a top front frame 23, a first connecting rod 24, and a second connecting rod 25.

The first connecting rod 24 is fixedly connected to the lower front frame 21 and the middle front frame 22 at its upper and lower ends, respectively, and the second connecting rod 25 is fixedly connected to the middle front frame 22 and the top front frame 23 at its upper and lower ends, respectively. These connecting rods greatly enhance the longitudinal rigidity and torsional resistance of the front frame 2. The lower front frame 21 is constructed as a polygonal frame to improve structural stability.

[0030] Through the coordinated action of the battery partition frame 12, the outer frame support frame 16, and the outer frame connecting frame 17, a high-rigidity base frame 1 is formed. The multi-layered parallel frame and vertical connecting rod design of the front frame 2 forms a stable spatial truss structure, significantly improving the overall torsional and impact resistance.

[0031] The battery compartment is centrally and neatly arranged between two battery partition frames 12, with a compact layout that facilitates battery pack installation and maintenance. The front wheel rims 13 and rear wheel rims 14 are located on either side of the battery compartment, optimizing the vehicle's center of gravity and improving driving stability. Furthermore, a preferred embodiment of the lower frame 21 of the vehicle front is a hexagonal structure, including a long side 211, a short side 212, side edges 213, and inclined edges 214.
