[0056] Embodiment 1
[0057] like Figure 1 , Figure 2 as well as Figure 3 , Figure 4 As shown, the present invention provides a brake cable drive device for a split lock, including a motor 1 (see Figure 7 ), a control panel (not shown in the figure) and a sensor (not shown in the figure); the control panel is electrically connected to the motor 1 and the sensor respectively;
[0058] The above-mentioned sensor is used to detect the braking state and send it to the control panel, and the control panel controls the running state of the motor according to the braking state; the above-mentioned motor 1 is used to be connected to the brake cable A to drive the brake cable A to move.
[0059] The above sensor can detect the tension of the brake cable (or brake force), the motor transmission and the output torque of the motor, etc. The above control panel can coordinately control the output power and output torque of the motor, and finally realize the control of the braking force;
[0060] The sensor and control panel are the core of the control part, which are used to adjust and control the motor; at the same time, the motor is connected to the brake cable to drive the brake cable pulling action, and finally realize the braking force control of the brake device. The sensor is used to detect the braking state and send it to the control panel; at the same time, the control panel controls the running state of the motor according to the braking state. In the specific application process, when the motor rotates and outputs a certain number of circles or a certain torque, a certain output power, the pulling stroke of the brake cable can be adjusted and changed (a certain pulling force is obtained). Under the action of this stretching stroke, the brake cable can be driven to achieve a certain degree of braking force (this braking force can be half braking or fixed-point full braking); the motor is controlled through the electronic control part of the control panel, which is finally reflected in the stroke control or pulling force control of the above-mentioned brake cable, thereby realizing the electric control of the roller brake.
[0061] like Figure 1-Figure 4 As shown, the brake cable drive device of the split lock also includes a cable winding wheel 2 (see Figure 8 ); the motor 1 is used to drive the wire pulling reel 2 to rotate, and the wire pulling reel 2 is used to wind the brake wire A.
[0062] It should be noted that in the specific technical scheme of the embodiment of the present invention, during the specific assembly, the brake wire driving device of the split lock can drive the wire winding wheel to rotate, and the brake wire is wound in the circumferential inner groove of the wire winding wheel to form a fixed connection; in this way, the motor can be used to drive the above-mentioned wire winding wheel to rotate to change the stroke of the brake wire, etc., thereby realizing the control of the braking force or the locking force.
[0063] As an implementable solution; the above-mentioned sensor is a Hall sensor; the Hall sensor is used to detect the rotation speed of the wire pulling winding wheel; the control panel is used to convert the current rotation speed into the number of rotations; it is also used to control the rotation action of the motor after receiving the braking control instruction, adjust the number of rotations of the wire pulling winding wheel to reach the target number of rotations, thereby controlling the stroke of the brake wire and finally achieving control of the braking force.
[0064] It should be noted that in the specific technical solution of the embodiment of the present invention, the Hall sensor is used to detect the rotation speed of the wire pulling winding wheel, and the control panel is used to convert the current rotation speed into the number of rotations. However, the control panel presets a target number of rotations to achieve the target braking force or locking force, and then controls the motor to rotate. When the motor reaches the target value, the corresponding control purpose is achieved.
[0065] As an implementable solution, the above-mentioned sensor is a tension sensor; the tension sensor is used to detect the tension of the brake cable; the control panel is used to adjust the tension of the brake cable to reach the target value through the rotation of the motor after receiving the brake control command, thereby finally realizing the control of the braking force.

[0067] As an implementable solution, the above-mentioned sensor is a torque sensor; the torque sensor is used to detect the output torque of the motor; the control panel is used to control the rotation of the motor after receiving the braking control command, adjust the output torque of the control motor to reach the target value, and finally realize the control of the braking force.
[0068] It should be noted that the torque sensor (also known as torque sensor, torque sensor, torque sensor, torque meter) is a detector of the torsional torque perception on various rotating or non-rotating mechanical parts. The torque sensor converts the physical change of torque into an accurate electrical signal. The torque sensor can be used in the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches. It has the advantages of high precision, fast frequency response, good reliability, and long life. The above-mentioned control panel is adjusted according to the detected output torque, and finally ensures that the output torque of the control motor reaches the target value (for example: the output torque value of the braking force or the locking force is achieved), and then the corresponding control purpose can be achieved.

[0070] It should be noted that in the specific technical scheme of the embodiment of the present invention, a transmission mechanism is also designed in the motor drive device; the transmission mechanism is arranged between the motor and the wire pulling winding wheel, and the main function of the transmission mechanism is to realize the transmission of the output power of the motor to the wire pulling winding wheel, thereby driving the wire pulling winding wheel to rotate.

[0072] It should be noted that in the specific technical scheme of the embodiment of the present invention, the above-mentioned transmission mechanism includes but is not limited to the use of a gear set, and other transmission mechanisms may also be implemented. However, in the preferred scheme, it is preferred to use a gear set. The above-mentioned gear set realizes stable and reliable power transmission, ensures that the wire pulling and winding wheel rotates smoothly, thereby ensuring that the final output braking force is also more stable.
[0073] like Figure 1 , Figure 2 as well as Figure 3 As shown, the brake cable drive device of the split lock also includes a drive device housing 4; the drive device housing 4 is used to store the motor 1, the cable winding wheel 2 and the gear set.
[0074] It should be noted that in the specific technical scheme of the embodiment of the present invention, the brake wire drive device of the above-mentioned split lock is also designed with a drive device housing, which is used to encapsulate and protect the internal motor and wire winding wheel, gear set and other structures, which is beneficial to achieve waterproof, dustproof and other protection for the brake wire drive device of the split lock.
[0075] like Fig.12 as well as Fig.13 As shown, the drive device housing 4 includes an upper housing 41 and a lower housing 42; the upper housing 41 and the lower housing 42 are detachably connected by bolts.
[0076] It should be noted that in the specific technical solution of the embodiment of the present invention, the drive device housing includes an upper shell and a lower shell, and the two are detachably connected by bolts.

[0077] like Figure 3 as well as Figure 4 As shown, the interior of the driving device housing 4 is also provided with a gear set fixing frame 5 (see Fig.10 ) and gear set protective housing 6 (see Fig.11 );
[0078] Among them, the gear group fixing frame is detachably connected to the inner side of the lower shell body; the gear group is arranged on one side of the gear group fixing frame, and the wire pulling winding wheel is located outside the lower shell body on the other side of the gear group fixing frame; the gear group and the wire pulling winding wheel are matched through the transmission shaft; and the gear group protective shell is connected to the side of the gear group fixing frame where the gear group is installed.
[0079] It should be noted that in the specific technical scheme of the embodiment of the present invention, a gear set fixing frame and a gear set protective shell are also provided inside the driving device housing; the gear set protective shell serves to encapsulate the gear set; and at the same time, the gear set fixing frame is used to install and fix the gear set and the wire pulling winding wheel.
[0080] like Figure 8 As shown, the wire pulling reel 2 comprises a wire winding groove portion 21 for winding the brake wire; the wire winding groove portion 21 is extended along the circumferential direction of the wire pulling reel 2.
[0081] It should be noted that in the specific technical solution of the embodiment of the present invention, a wire winding wheel is provided with a wire winding groove portion along the circumferential wall direction, and the main function of the wire winding groove portion is to facilitate the winding and fixing of the brake wire. During the specific assembly, the motor can drive the wire winding wheel to rotate, and the brake wire is wound in the circumferential inner groove of the wire winding wheel (i.e., the wire winding groove portion) and forms a fixed connection; finally, the motor is used to drive the wire winding wheel to rotate to change the travel of the brake wire, thereby realizing the control of the braking force.
[0082] like Figure 4 As shown, a concave winding wheel accommodating cavity 43 is provided on the surface of the lower shell 42, and the winding wheel accommodating cavity 43 is used to accommodate the wire pulling winding wheel 2, and a notch 44 is provided at the edge of the winding wheel accommodating cavity 43 for facilitating the pulling of the brake wire.
[0083] It should be noted that in the specific technical scheme of the embodiment of the present invention, a concave winding wheel accommodating cavity is arranged on the surface of the above-mentioned lower shell body, and the winding wheel accommodating cavity is used to accommodate the wire pulling winding wheel. The design of the above-mentioned concave winding wheel accommodating cavity can ensure that the wire pulling winding wheel is safely and partially hidden in the winding wheel accommodating cavity to form a certain degree of protection. At the same time, the edge of the winding wheel accommodating cavity is also designed with a notch, and the notch is for facilitating the free entry and exit of the brake cable.
[0084] like Figure 3 as well as Figure 4 As shown, the gear set protective housing 6 and the gear set fixing frame 5 are detachably connected via bolts.

[0086] Waterproof guide grooves are also provided at the outer edges of the upper shell 41 and the lower shell 42 (not shown in the figure, the waterproof guide grooves can prevent water from entering the brake cable drive device of the split lock and causing short circuit of electrical equipment, etc.).
[0087] The wire pulling and winding wheel 2 is any one of a carbon fiber structure wheel, a tungsten alloy structure wheel and a stainless steel structure wheel.
[0088] It should be noted that in the specific technical scheme of the embodiment of the present invention, the above-mentioned wire drawing winding wheel can be designed in various forms, but in the most preferred scheme, it is preferred to use a carbon fiber structural wheel or any one of a tungsten alloy structural wheel and a stainless steel structural wheel. The above-mentioned carbon fiber structural wheel has a light structure and high wear resistance, and can be suitable for the structural material selection of the wire drawing winding wheel. At the same time, the tungsten alloy structural wheel and the stainless steel structural wheel also have strong wear resistance and high deformation resistance, and are also suitable for the structural material selection of the wire drawing winding wheel.

In this way, when the roller brake is braking, its motor starts to rotate, the gear set moves, and the cable winding wheel starts to rotate, thereby driving the brake cable to travel a certain distance; after achieving a certain distance, its innermost gear-shaped steel ring rotates, and the gear lifts up each cylindrical steel ball, so that multiple (six) cylindrical steel balls expand outward, and the diameter of the structure surrounded by the cylindrical steel balls increases; after the diameter increases outward, the steel balls are forced to contact multiple brake pads (usually three), and the brake pads are expanded to the outer layer, and at this time, multiple brake pads move outward at the same time by a certain distance; finally, the brake pads are forced to contact the inner wall of the outermost brake drum to realize electric control braking; the braking force control of the above-mentioned electric control brake is more stable, more reliable, and the control accuracy is also higher.

At the same time, the above-mentioned sensor can detect the output power and output torque of the drive mechanism or directly detect the tension acting on the brake cable.
[0093] Correspondingly, the present invention also provides a vehicle, including a vehicle body, a brake device and a brake cable driving device of a split lock arranged on the vehicle body; the brake device includes a brake cable for realizing braking force control; the brake cable driving device of the split lock is connected to the brake device through the brake cable.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
