[0034] According to the utility model, a large-scale automatic driving logistics vehicle with a two-way driving function is provided. Figures 1 to 5 As shown, the large-scale self-driving logistics vehicle with a two-way driving function is used in a production logistics park. The large-scale self-driving logistics vehicle with a two-way driving function includes a body 1 and a walking frame 2.

[0035] In the following description, reference will be made to Figures 1 to 5 The detailed structure of the body 1 and the traveling frame 2 of the large-scale automatic driving logistics vehicle with a two-way driving function is specifically described.

[0036] like Figure 1 and Figure 2 As shown, in the embodiment, the large-scale self-driving logistics vehicle with two-way driving function is designed as a symmetrical structure. Figure 2 As shown, the installation and layout of various components of the large-scale self-driving logistics vehicle with two-way driving function are based on the symmetrical center line S1 as the reference line, so that the large-scale self-driving logistics vehicle has the function of two-way driving, does not need to turn around, reduces the docking time, and when docking, the goods inside the logistics vehicle can be connected from two ports, which increases the flexibility of docking.

[0037] Specifically, the vehicle body 1 includes a symmetrically arranged first docking end 101, a second docking end 102 and a transmission part 103 for transporting and storing goods. The first docking end 101 and the second docking end 102 both include a docking port 104. The transmission part 103 is arranged inside the vehicle body 1, and both ends of the transmission part 103 are connected to the docking port 104 of the first docking end 101 and the docking port 104 of the second docking end 102. In this way, the goods can enter from the docking port 104 of the first docking end 101 and then be sent out through the docking port 104 of the second docking end 102, or enter from the docking port 104 of the first docking end 101 and be sent out from the docking port 104 of the first docking end 101, thereby increasing the flexibility of cargo docking and realizing two-way docking of the autonomous driving logistics vehicle. There is no need to turn around when transporting goods, and the goods can be transported from the two docking ports 104.

[0038] In addition, it should be noted that the large-scale in the large-scale autonomous driving logistics vehicle refers to the large overall size of the vehicle. In the embodiment, the vehicle is 3187 mm high, 2380 mm wide, and the vehicle mass is greater than 7000 kg. In this way, when the vehicle size and weight are large, it can realize the transportation of large goods and the weight and quantity of goods that can be transported are also large.

[0039] The walking frame 2 is arranged at the bottom of the vehicle body 1, and is used as a load-bearing component of the whole vehicle to bear the weight of the vehicle itself and the weight of the goods, and can realize the walking of the automatic driving logistics vehicle. The walking frame 2 may include a first walking end 201 and a second walking end 202 that are symmetrically arranged, and the first walking end 201 and the second walking end 202 both include a walking device, and the walking device includes a driving component 203 for power output and a walking component 204 for driving the vehicle body 1 to walk. The first walking end 201 and the second walking end 202 can independently realize walking (including forward, backward and turning), acceleration, deceleration and braking. In an embodiment, through the regulation of the electronic control component, the first walking end 201 and the second walking end 202 can move simultaneously to achieve a turning with a smaller turning radius, that is, the four wheels 205 of the first walking end 201 and the second walking end 202 turn at the same time, thereby realizing a turning in a small space. And after a failure occurs at one walking end, the other walking end can keep the whole vehicle walking. The regulation of the electronic control components mentioned here is a control method in the prior art, for example, EPS (electric steering by wire) is adopted, which can be known to those skilled in the art.

Since the vehicle is driven by the electronic control system, the vehicle is driven automatically, so there is no need to set up a cab, and the internal storage space is improved, which increases the cargo carrying capacity. The first docking end 101 and the second docking end 102 can realize two-way docking, and the vehicle does not need to turn around to achieve the docking of goods, which ensures the accuracy of the docking, reduces the docking time, and improves the logistics transportation efficiency. In addition, since each walking end of the large-scale self-driving logistics vehicle with two-way driving function is controlled and driven by a separate walking device, it can turn and transport goods in a restricted area.

Through a separate device, the two wheels 205 of the first walking end 201 and the two wheels 205 of the second walking end 202 are controlled separately, and when turning, the four wheels 205 can all move at the same time, thereby achieving a smaller radius of turning.

Specifically, the driving motor 2031 outputs a driving force through an output end, which may be, for example, a driving force that causes the wheels 205 to rotate forward or reversely through a gear forward or reverse output, thereby causing the vehicle to move forward or backward, and the driving motor 2031 is connected to the speed reducer 2032, and the driving force is output to the differential 2041 through the speed reducer 2032, and the differential 2041 transmits the driving force to the driving steering axle 2042, and the driving steering axle 2042 is connected to the two wheels 205. The driving steering axle 2042 can cause the two wheels 205 to rotate and turn. The electronic parking brake assembly 2033 is connected to the speed reducer 2032, and can brake the wheels 205 when parking or deceleration is required. It should be noted that the drive motor 2031, the reducer 2032, the electronic parking brake assembly 2033, the differential 2041 and the drive steering axle 2042 can all be components in the prior art, and their structures, principles, usage and installation methods are all known to those skilled in the art.
