[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown, a frame of an EMB-based unmanned logistics vehicle includes an electric brake 6, a frame body 1, a steering bridge 2, and a drive bridge 4. The steering bridge 2 and the drive bridge 4 are respectively fixed to both ends of the frame body 1. The steering bridge 2 is rotatably provided with a front steering seat 3 at both ends. The drive bridge 4 is provided with a connecting seat 5 at both ends. The electric brake 6 is respectively fixed on the front steering seat 3 and the connecting seat 5.

[0019] EMB stands for Electromechanical Brake, also known as Electric Brake 6, and is a commercially available product.

[0020] Both the front steering seat 3 and the connecting seat 5 are rotatably connected to the brake disc, and the electric brake 6 is set opposite to the brake disc.

[0021] Since the electric brake 6 does not require a hydraulic system, it greatly reduces the number of parts and the amount of assembly work, making assembly more convenient and faster. It also simplifies the frame structure and makes the connection of the electric brake 6 simpler, thus reducing costs.

[0022] To facilitate the installation of the electric brake 6, the front steering seat 3 is provided with a first fixing platform 31, which has a first fixing hole 32. The first fixing hole 32 is connected to the electric brake 6 by bolts. The connecting seat 5 is provided with a second fixing platform 52, which has a second fixing hole 53. The second fixing hole 53 is connected to the electric brake 6 by bolts.

[0023] The front steering seat 3 is also connected to the steering system for controlling the steering of the front wheels. The remaining structures of the steering bridge 2 and drive bridge 4 are existing mature technologies and will not be described in detail here.

[0024] like Figure 6 and Figure 7 As shown, to further improve control reliability and ensure reliable braking in conjunction with the electric brake 6, a first wheel speed sensor 91 and a second wheel speed sensor 92 are also included. The first wheel speed sensor 91 is fixed on the first detection boss 33 of the steering bridge 2 and is positioned opposite to the first detection tooth 22, used to detect the rotational speed of the two front wheels in real time. The first detection tooth 22 is located on the wheel hub 21 and arranged in a circular array along the axis. The second wheel speed sensor 92 is fixed on the second detection boss 51 of the drive bridge 4 and is positioned opposite to the second detection tooth, used to detect the rotational speed of the two rear wheels in real time. The second detection tooth is located on the outer circumferential surface of the drive shaft within the drive bridge and arranged in a circular array along the axis. By detecting the real-time rotational speeds of the front and rear wheels, the braking force can be precisely controlled, thereby ensuring smooth and reliable braking.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
