Description

Technical Field

[0001] This utility model relates to the technical field of unmanned vehicle chassis, specifically to an unmanned vehicle chassis frame reinforcement structure. Background Technology

[0002] In the logistics industry, unmanned vehicle delivery is commonly used to solve the "last mile" problem in logistics transportation. This involves unmanned delivery of packages to the final destination, improving transportation efficiency and saving labor costs. Typically, the steering system of an unmanned vehicle chassis uses automotive-grade EPS steering. This type of steering has low precision and poor retrofitting capabilities. EPS stands for Electric Power Steering, which is a power steering system that relies on an electric motor to provide auxiliary torque.

[0003] According to Chinese patent CN214930229U, an unmanned vehicle chassis structure is disclosed. The unmanned vehicle chassis includes a power system, a braking system, a steering system, and a vehicle frame. The power system includes a power battery system and a dual-hub motor rear-drive system, which is fixed to the rear wheels of the unmanned vehicle. The braking system is a steer-by-wire electro-hydraulic brake system, and the steering system is a steer-by-wire system. The vehicle frame is used to fix the power battery system, braking system, and steering system. An upper sealing plate is located opposite the vehicle frame to enclose it. The vehicle frame is connected to the front wheels using a double wishbone front suspension.

[0004] In the above solution, the front and rear body frames are directly connected to form the vehicle frame, which has the following disadvantages: when in use, the overall structural strength of the frame is low, and therefore it cannot withstand greater loads and impacts, resulting in a reduction in the service life and safety of the frame. Utility Model Content

[0005] The purpose of this utility model is to provide a chassis frame reinforcement structure for unmanned vehicles, in order to solve the problem that the overall structural strength of the frame is low during use, which makes it unable to withstand greater loads and impacts, thus reducing the service life and safety of the frame.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a chassis frame reinforcement structure for an unmanned vehicle, including a front frame, the front frame being fixed to the front side of the outer wall of the main frame, a rear frame being fixed to the rear side of the outer wall of the main frame, two reinforcing crossbeams being fixed inside the main frame, several reinforcing curved beams being fixed between the two reinforcing crossbeams and the main frame, a first longitudinal beam being fixed between the front frame and the main frame, a second longitudinal beam being fixed between the rear frame and the main frame, and two first reinforcing ribs being fixed to the front and rear sides of the outer wall of the main frame, the top surfaces of the two first reinforcing ribs on the front side being fixedly connected to the bottom surface of the front frame, and the top surfaces of the two first reinforcing ribs on the rear side being fixedly connected to the bottom surface of the rear frame.

[0007] Preferably, a plurality of first triangular plates are fixed inside the main frame, a plurality of second triangular plates are fixed between the front frame and the main frame, and a plurality of third triangular plates are fixed between the rear frame and the main frame.

[0008] Preferably, a first side plate is fixed between the left and right sides of the front frame and the left and right sides of the main frame, and a second side plate is fixed between the left and right sides of the rear frame and the left and right sides of the main frame.

[0009] Preferably, a number of uprights are fixed inside the main frame, a second reinforcing rib is fixed between the upright on the front side and the first longitudinal beam, and a third reinforcing rib is fixed between the upright on the rear side and the second longitudinal beam.

[0010] Preferably, a first diagonal brace is fixed to the left and right sides of the first longitudinal beam, and the two first diagonal braces are fixedly connected to the inner wall of the front frame. A second diagonal brace is fixed to the left and right sides of the second longitudinal beam, and the two second diagonal braces are fixedly connected to the inner wall of the rear frame.

[0011] Preferably, two first fixing plates are fixed to the left and right sides of the first longitudinal beam, the two first fixing plates on the front side are fixedly connected to the inner wall of the front frame, and the two first fixing plates on the rear side are fixedly connected to the front side of the outer wall of the main frame. Two second fixing plates are fixed to the left and right sides of the second longitudinal beam, the two second fixing plates on the front side are fixedly connected to the rear side of the outer wall of the main frame, and the two second fixing plates on the rear side are fixedly connected to the inner wall of the rear frame.

[0012] Compared with existing technologies, the unmanned vehicle chassis frame reinforcement structure that adopts the above technical solution has the following beneficial effects:

[0013] 1. In use, the combined use of reinforced crossbeams, reinforced curved beams, first longitudinal beams, second longitudinal beams and first reinforcing ribs helps to reinforce the front frame, main frame and rear frame, and strengthen the connection between them, thereby improving the overall structural strength of the frame, enabling it to withstand greater loads and impacts, thus improving the service life and safety of the frame.

[0014] Second, during use, the first triangular plate effectively disperses the stress inside the main frame, preventing deformation and torsion. Simultaneously, the combined use of the second and third triangular plates not only enhances the connection strength between the frames but also improves the overall rigidity and stability of the frame through the stability principle of triangles, reducing stress concentration and increasing frame durability. The first side plate effectively prevents relative displacement between the front frame and the main frame under lateral forces, while the second side plate serves the same purpose, reinforcing the lateral connection between the rear frame and the main frame. These side plates not only increase the contact area between the frames but also enhance the overall frame's anti-roll capability through their rigidity and stability.

[0015] Thirdly, during use, the uprights effectively support and reinforce the main frame. Simultaneously, the second and third reinforcing ribs increase the contact area and distribute stress, further enhancing the connection strength between the uprights and the longitudinal beams, allowing the frame to withstand greater vertical loads. The first diagonal brace effectively prevents the first longitudinal beam from bending and deforming under stress, while the second diagonal brace serves the same purpose, reinforcing the connection between the second longitudinal beam and the rear frame. These diagonal braces not only increase the rigidity and stability of the frame but also optimize the stress state of the frame through their inclination angle. The first fixing plate effectively prevents the relative displacement of the first longitudinal beam under stress. The second fixing plate serves the same purpose, reinforcing the connection between the second longitudinal beam and the rear and main frames. It not only increases the contact area between the frames but also enhances the overall connection strength and stability of the frame through its rigidity and stability. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, an unmanned vehicle chassis frame reinforcement structure includes a front frame 1, which is fixed to the front side of the outer wall of the main frame 2. A rear frame 3 is fixed to the rear side of the outer wall of the main frame 2. Two reinforcing crossbeams 4 are fixed inside the main frame 2. Several reinforcing curved beams 5 are fixed between the two reinforcing crossbeams 4 and the main frame 2. A first longitudinal beam 6 is fixed between the front frame 1 and the main frame 2. A second longitudinal beam 7 is fixed between the rear frame 3 and the main frame 2. Two first reinforcing ribs 8 are fixed to the front and rear sides of the outer wall of the main frame 2. The top surfaces of the two first reinforcing ribs 8 on the front side are fixedly connected to the bottom surface of the front frame 1, and the top surfaces of the two first reinforcing ribs 8 on the rear side are fixedly connected to the bottom surface of the rear frame 3.

[0023] In use, the reinforcing crossbeam 4 strengthens the main frame 2, enhancing its bending and torsional resistance. The reinforcing curved beam 5 further disperses stress from various directions, making the main frame 2 more stable. The first longitudinal beam 6 reinforces the connection between the front frame 1 and the main frame 2, effectively preventing relative displacement. The second longitudinal beam 7 serves the same purpose, reinforcing the connection between the rear frame 3 and the main frame 2. The first reinforcing rib 8 further strengthens the connections between the front frame 1, the rear frame 3, and the main frame 2, increasing the contact area and dispersing stress, thus improving the strength and stability of the connections. The combined use of the reinforcing crossbeam 4, reinforcing curved beam 5, first longitudinal beam 6, second longitudinal beam 7, and first reinforcing rib 8 strengthens the front frame 1, main frame 2, and rear frame 3, and reinforces their connections, thereby improving the overall structural strength of the frame. This allows it to withstand greater loads and impacts, improving the frame's service life and safety.

[0024] like Figures 1-4 As shown, several first triangular plates 9 are fixed inside the main frame 2, several second triangular plates 10 are fixed between the front frame 1 and the main frame 2, and several third triangular plates 11 are fixed between the rear frame 3 and the main frame 2.

[0025] In use, the first triangle plate 9 effectively disperses the stress inside the main frame 2, preventing deformation and twisting of the frame. At the same time, the combined use of the second triangle plate 10 and the third triangle plate 11 not only enhances the connection strength between the frames, but also improves the rigidity and stability of the entire frame through the stability principle of triangles, reducing stress concentration and improving the durability of the frame.

[0026] like Figures 1-4 As shown, first side plates 12 are fixed between the left and right sides of the front frame 1 and the left and right sides of the main frame 2, and second side plates 13 are fixed between the left and right sides of the rear frame 3 and the left and right sides of the main frame 2. Several uprights 14 are fixed inside the main frame 2. A second reinforcing rib plate 15 is fixed between the front upright 14 and the first longitudinal beam 6, and a third reinforcing rib plate 16 is fixed between the rear upright 14 and the second longitudinal beam 7.

[0027] In use, the first side plate 12 effectively prevents relative displacement between the front frame 1 and the main frame 2 under lateral forces. The second side plate 13 serves the same purpose, reinforcing the lateral connection between the rear frame 3 and the main frame 2. These side plates not only increase the contact area between the frames but also enhance the overall frame's anti-roll capability through their rigidity and stability. The uprights 14 serve to support and reinforce the main frame 2. Meanwhile, the second and third reinforcing ribs 15 and 16 further enhance the connection strength between the uprights 14 and the longitudinal beams by increasing the contact area and dispersing stress, enabling the frame to withstand greater vertical loads.

[0028] like Figures 1-4 As shown, the left and right sides of the first longitudinal beam 6 are respectively fixed with first diagonal rods 17, and the two first diagonal rods 17 are respectively fixedly connected to the inner wall of the front frame 1. The left and right sides of the second longitudinal beam 7 are respectively fixed with second diagonal rods 18, and the two second diagonal rods 18 are respectively fixedly connected to the inner wall of the rear frame 3. The left and right sides of the first longitudinal beam 6 are respectively fixed with two first fixing plates 19. The two first fixing plates 19 on the front side are respectively fixedly connected to the inner wall of the front frame 1, and the two first fixing plates 19 on the rear side are respectively fixedly connected to the front side of the outer wall of the main frame 2. The left and right sides of the second longitudinal beam 7 are respectively fixed with two second fixing plates 20. The two second fixing plates 20 on the front side are respectively fixedly connected to the rear side of the outer wall of the main frame 2, and the two second fixing plates 20 on the rear side are respectively fixedly connected to the inner wall of the rear frame 3.

[0029] In use, the first diagonal brace 17 effectively prevents the first longitudinal beam 6 from bending and deforming under stress, while the second diagonal brace 18 serves the same purpose, reinforcing the connection between the second longitudinal beam 7 and the rear frame 3. These diagonal braces not only increase the rigidity and stability of the frame but also optimize the stress state of the frame through their tilt angle. The first fixing plate 19 effectively prevents the relative displacement of the first longitudinal beam 6 under stress. The second fixing plate 20 serves the same purpose, reinforcing the connection between the second longitudinal beam 7 and the rear frame 3 and the main frame 2. It not only increases the contact area between the frames but also improves the connection strength and stability of the entire frame through its rigidity and stability.
