Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-2 As shown, an embodiment of this utility model provides a synchronous braking device, which includes: The system includes a braking unit, a traction connection assembly 1, a signal assembly, and a braking control assembly 2. One end of the traction connection assembly 1 forms a connection end that connects to the power vehicle, and the other end forms a bearing end. The signal assembly is located at the power vehicle and is used to sense or collect braking signals and braking force signals. The braking control assembly 2 is fixed on the bearing end and is electrically connected to the sensing assembly and the braking unit. It receives braking signals and braking force signals sensed or collected by the signal assembly and drives the braking unit to operate.

[0020] In this invention, a braking unit, a traction connection assembly 1, a signal assembly, and a braking control assembly 2 are provided. The signal assembly is located at the power vehicle and is used to sense or collect braking signals and braking force signals. The braking control assembly 2 is fixed on the bearing end and electrically connected to the sensing assembly and the braking unit. It receives the braking signals sensed or collected by the signal assembly and drives the braking unit to operate, enabling the trailer to obtain braking signals and braking force signals. Based on these signals, the trailer's braking unit is driven to perform corresponding actions, thereby enabling the traction vehicle and the trailer to brake synchronously, improving braking effect and ensuring driving safety. In actual use, the synchronous braking device is independent of the preceding vehicle. Only the synchronous braking device needs to be installed on the trailer to achieve braking control of the trailer, without the need to modify or recalibrate the preceding vehicle, reducing the operating cost of the trailer and improving its adaptability.

[0021] Specifically, the braking unit includes a braking unit and a hydraulic unit. The braking unit and the hydraulic unit are connected by a pipeline. The hydraulic unit is electrically connected to the braking control component 2. The hydraulic unit applies hydraulic pressure to the braking unit according to the signal from the braking control component 2 to achieve braking.

[0022] Furthermore, the hydraulic unit includes a cylinder, a piston, and a telescopic motor. The cylinder is equipped with a pipeline connected to the brake unit. One end of the piston is connected to the cylinder, and the other end is connected to the movable end of the telescopic motor. The telescopic motor is electrically connected to the brake control assembly 2. Under the drive of the brake control assembly 2, the movable end of the telescopic motor extends, compressing the piston, thereby driving the hydraulic fluid in the cylinder to flow through the pipeline to the brake unit, thus driving the brake unit to perform braking.

[0023] Furthermore, the piston component includes a piston cylinder and a piston rod. The piston cylinder is connected to the hydraulic cylinder. One end of the piston rod forms a piston, extending into the piston cylinder and being movably and sealingly connected to it. The other end of the piston rod is connected to the movable end of the telescopic motor. When the movable end of the telescopic motor extends, the piston rod moves, compressing the internal space of the piston cylinder. This compresses the hydraulic fluid in the hydraulic cylinder, driving it to flow through the pipeline to the brake unit, thus driving the brake unit to apply the brakes. Conversely, when the movable end of the telescopic motor retracts, the piston rod moves, increasing the internal space of the piston cylinder. This causes the hydraulic fluid to flow back through the pipeline, disengaging the brake unit from the braking state.

[0024] Specifically, the braking unit is a conventional device on the market, which realizes the braking function under hydraulic drive. Its specific structure is well known to those skilled in the art, so it will not be described in detail here.

[0025] Specifically, the traction connection assembly 1 includes a housing 11, a connecting seat 12, a connecting rod 13, and an elastic element. An installation space is formed inside the housing 11. The connecting seat 12 is fixed to the inner wall of the housing 11. The connecting rod 13, the elastic element, and the brake control assembly 2 are all disposed within the installation space. The connecting rod 13 is movably inserted through the connecting seat 12. The elastic element is sleeved on the connecting rod 13, with one end fixed to the connecting seat 12 and the other end fixed to the connecting rod 13. One end of the connecting rod 13 forms a connection end for connecting to the traction vehicle, and the other end of the connecting rod 13 is movably connected to the connecting seat 12.

[0026] Furthermore, the traction connection assembly 1 also includes a support plate 14, which is located at the end of the connecting rod 13 away from the traction vehicle and can limit the connection rod 13. The two ends of the support plate 14 are fixed to the inner wall of the housing 11, supporting the internal space of the housing 11 and increasing the strength of the housing 11.

[0027] Furthermore, the braking control component 2 is fixed to the support cross plate 14.

[0028] Specifically, the signal component is used to acquire braking signals. In some embodiments, the signal component includes a signal collector that is electrically connected to the controller of the traction vehicle and the braking control component 2 to acquire the braking signals of the traction vehicle.

[0029] Furthermore, the signal component includes an acceleration sensor, which is fixed to the traction vehicle and electrically connected to the brake control component 2. The acceleration sensor is used to sense changes in the acceleration of the traction vehicle to generate a braking force signal.

[0030] Furthermore, it also includes a buffer assembly, which is fixed to the support cross plate 14 to buffer the movement of the connecting rod 13.

[0031] Furthermore, the buffer assembly includes a buffer and a connecting rod. The buffer is fixed to the support plate 14. The movable end of the buffer is connected to one end of the connecting rod and can extend and retract relative to the buffer. The other end of the connecting rod is connected to the connecting rod. The buffer 31 is configured to slow down the movement of the movable end of the buffer. The buffer can slow down the extension and retraction process of the movable end of the buffer.

[0032] Furthermore, the bottom of the housing 11 is provided with an inspection port 111, and a dust cover 112 is detachably connected to the inspection port 111, covering the inspection port 111. When it is necessary to repair the device inside the housing 11, the dust cover 112 can be removed to repair the interior.

[0033] The beneficial effects of this utility model are: This utility model includes a braking unit, a traction connection assembly, a signal assembly, and a braking control assembly. One end of the traction connection assembly forms a connection end that connects to the power vehicle, and the other end forms a bearing end.

This invention includes a braking unit, a traction connection assembly, a signal assembly, and a braking control assembly. These devices are all mounted on the trailer and are independent of the towing vehicle. The signal assembly is located on the power vehicle and is used to sense or collect braking signals and braking force signals. The braking control assembly is fixed to the bearing end and electrically connected to the sensing assembly and the braking unit. It receives the braking signals and braking force signals sensed or collected by the signal assembly and drives the braking unit to operate, enabling the trailer to obtain braking signals and braking force signals.
