[0028] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0029] Please refer to Figures 1-6 As shown, the drum-type cruise control device disclosed in this embodiment includes a rear shell 1 with an open outer side and a cover plate 2 provided on the outer side of the rear shell 1 for sealing the rear shell 1. The rear shell 1 and the cover plate 2 are assembled to form a mounting shell, and a through hole 17 for the throttle handle to pass through is provided on the surface of the mounting shell; the inner cavity of the rear shell 1 is divided into a mounting cavity 3, a locking cavity 4 and a connecting cavity 5, respectively. The mounting cavity 3 is located at the bottom of the inner cavity of the rear shell 1, the locking cavity 4 is located in the inner cavity of the rear shell 1 and is located above the mounting cavity 3 shown and is connected to the mounting cavity 3. The locking cavity 4 is circular in shape, and the connecting cavity 5 is located on one side of the locking cavity 4 and is located above the mounting cavity 3 and is connected to the mounting cavity 3.

[0030] An auxiliary ring 18 is detachably provided in the inner cavity of the through hole 17. The outer ring surface of the auxiliary ring 18 contacts the inner wall surface of the through hole 17, and the inner ring surface of the auxiliary ring 18 contacts the throttle handle of the motorcycle. The auxiliary ring 18 has a certain elasticity and can produce a certain elastic deformation, so as to better fit the handle and increase the friction of the throttle handle; the inner cavity of the locking cavity 4 is provided with a locking mechanism for limiting the throttle handle, the inner cavity of the locking cavity 4 is provided with a driving mechanism for driving the locking mechanism, and the inner cavity of the installation cavity 3 is provided with a positioning mechanism for limiting the driving mechanism.

[0031] The inner cavity of the installation cavity 3 is provided with a control switch 10. The control switch 10 is a mature existing technology. It is connected to the power supply module and the drive module. When it is closed, the negative signal of the power supply module cannot be sent to the drive module. When it is opened, it means that it can be sent. The specific model is not limited; the positioning mechanism includes a rotating plate 8 rotatably connected to the inner cavity of the installation cavity 3. The middle part of the rotating plate 8 is bent downward to form a bending part. The rotating axis of the rotating plate 8 is located at the end away from the control switch 10, so that when one end of the control switch 10 moves downward, the other end moves upward, and vice versa. Therefore, the rotation of the rotating plate 8 can also be controlled by manual hand, so that the positioning mechanism can lock the drive mechanism or cancel the lock. A clamping member 29 for limiting the drive mechanism is provided on the top of the rotating plate 8. After the throttle handle is locked by the locking mechanism through the driving mechanism, the locking member is avoided by limiting the driving mechanism. When the throttle handle is locked, the rotating plate 8 is automatically rotated by the elastic force of the auxiliary spring 21, and the rotating plate 8 moves upward near the end of the control switch 10, and the clamping member 29 limits the driving mechanism.

[0032] It also includes a signal control switch module, a drive module, a winding module and a power supply module. The signal control switch module is connected to the power supply module to send a control signal to the power supply module, the power supply module is connected to the drive mechanism to send the positive signal of the power supply module to the drive mechanism, and the drive module is connected to the winding module to send a signal to the winding module for closing the circuit.

[0033] The locking mechanism includes two fixing rods 6 and two locking members 7 which are fixedly connected to the inner cavity of the locking cavity 4 in a mirror-image manner with the center of the locking cavity 4 as the center of the circle. One end of the two locking members 7 is rotatably connected to the inner cavity of the locking cavity 4 through the fixing rod 6, and the other end thereof can move toward the center of the locking cavity 4 when rotating. The auxiliary ring 18 is squeezed by the other ends of the two locking members 7 to make it fit the throttle handle to increase friction, and the throttle handle is pressed tightly to achieve the effect of locking the throttle handle.

[0034] The driving mechanism includes a detachable driving ring 15 which is arranged in the inner cavity of the locking cavity 4, and the driving ring 15 is in the shape of a hollow circular ring and has a certain elasticity. The hollow space meets the requirements of installing the auxiliary ring 18, and the driving ring 15 can rotate in the inner cavity of the locking cavity 4. Two sliding grooves 16 and two positioning grooves 31 are provided on the surface of the driving ring 15. The two sliding grooves 16 correspond one-to-one to the two fixed rods 6 and the two fixed rods 6 pass through the corresponding sliding grooves 16 respectively. A mounting block 26 is fixedly connected to the surface of the driving ring 15, and one end of the mounting block 26 passes through the outside of the rear shell 1. By pressing the end of the mounting block 26 that passes through the outside of the rear shell 1, the mounting block 26 can be rotated clockwise or counterclockwise, thereby rotating or resetting the locking member 7.

[0035] The surfaces of the two locking members 7 and one end away from the fixed rod 6 are fixedly connected with an auxiliary rod 14. The top ends of the two auxiliary rods 14 correspond one-to-one to the two positioning grooves 31 and pass through the corresponding positioning grooves 31. According to the above content, it can be known that the driving ring 15 is installed in the inner cavity of the locking cavity 4, and the fixed rod 6 passes through the sliding groove 16 and the auxiliary rod 14 passes through the positioning groove 31. The sliding groove 16 and the positioning groove 31 both meet the requirements of rotating the locking member 7 when the driving ring 15 is rotated. The movement direction of the other end is limited by the positioning groove 31, and the rotation of the rotating plate 8 is more stable through the fixed rod 6.

[0036] The outer ring surface of the driving ring 15 is recessed inward to form a locking groove 30, and the locking groove 30 and the outer ring surface of the driving ring 15 form an angle portion. When the throttle handle is not locked, the clamping piece 29 is in contact with the outer ring surface of the driving ring 15, and the elastic force of the auxiliary spring 21 makes the clamping piece 29 close to the outer ring surface of the driving ring 15. When the throttle handle needs to be locked, the driving ring 15 is rotated to drive the two locking pieces 7 to rotate and then move toward the auxiliary ring 18. While locking the throttle handle, due to the rotation of the driving ring 15 and under the elastic force of the auxiliary spring 21, when the position of the locking groove 30 corresponds to the position of the clamping piece 29, the auxiliary spring 21 causes the clamping piece 29 to move upward and engage with the locking groove 30 to achieve position limiting of the driving ring 15.

[0037] A pressure plate 19 is fixedly connected to the driving ring 15, one end of which passes through the inner cavity of the connecting chamber 5. The pressure plate 19 can move up and down in the vertical direction in the inner cavity of the connecting chamber 5, and because the pressure plate 19 is fixedly connected to the driving ring 15, it can drive the driving ring 15 to move clockwise or counterclockwise. The inner cavity of the connecting chamber 5 is provided with a fixed spring 20 for resetting the pressure plate 19. When the driving ring 15 rotates clockwise, the pressure plate 19 moves downward to squeeze the fixed spring 20 to generate elastic force. When the clamping member 29 is out of contact with the locking groove 30, the driving ring 15 rotates counterclockwise through the resetting of the fixed spring 20, and the locking member 7 is reset.

[0038] An upper movable groove 28 for the movement of the mounting block 26 is provided on the surface of the rear shell 1. The upper movable groove 28 is used to press the mounting block 26 to drive the drive ring 15 to rotate clockwise or counterclockwise, so that the throttle handle can be manually selectively locked and a movable groove 9 for the movement of one end of the rotating plate 8 can be provided. A fixed block 13 is provided at one end of the rotating plate 8. The movable groove 9 provided can enable the fixed block 13 and one end of the rotating plate 8 to move up and down in the vertical direction. Therefore, when the drive mechanism is locked or the limit is canceled, it will not be affected. Similarly, one end of the rotating plate 8 can be manually moved downward to cancel the limit on the drive mechanism.

[0039] The rear shell 1 is provided with a mounting mechanism for mounting to the vehicle body bracket, and the mounting mechanism includes a detachable mounting bracket 23 on the rear shell 1, and a lower support plate 24 is detachably provided on the outer end of the mounting bracket 23, and a recess is formed on the surface of the lower support plate 24 for contacting the lower surface of the vehicle body bracket. An upper locking plate 25 is detachably provided on the lower support plate 24, and when the lower support plate 24 and the upper locking plate 25 are assembled with each other, a clamp for clamping the vehicle body bracket is formed, thereby completing the fixation of the mounting shell, and a mounting hole 22 for installing the mounting bracket 23 is provided on the surface of the rear shell 1. Similarly, the rear shell 1 can be connected to the surface of the motorcycle frame by bolts. When it is directly connected to the frame body by bolts, there is no need for a mounting mechanism to install the rear shell 1.

[0040] An installation groove 11 for installing the adjusting member 12 is provided on the surface of the rotating plate 8. The installation groove 11 is circular in shape and a through groove is formed at its bottom for passing the rope portion of the adjusting member 12 through the inner cavity of the locking cavity 4. An auxiliary hole 27 is provided at the bottom of the rear shell 1, and the rope portion of the adjusting member 12 is connected to the winding module through the auxiliary hole 27.

[0041] A system of a drum-type cruise control device includes a signal control switch module, a drive module, a winding module and a power supply module, wherein the signal control switch module can specifically be a brake signal switch module, an anti-skid switch module, a traction switch or a speed detection switch with a sudden deceleration, and can also include a control switch group of multiple switch combinations of the brake signal switch module, the anti-skid switch module, the traction switch or the speed detection switch with a sudden deceleration, without detailed description or specific limitation. The above-mentioned signal control switch module is connected to the power supply module to transmit the control signal to the power supply module, the power supply module is connected to the drive mechanism to send the signal to the drive mechanism, and the drive module is connected to the winding module to send the signal to the winding module for closing the circuit. The system of the drum-type cruise control device also includes a drum-type cruise control device, wherein the control switch 10 in the drum-type cruise control device is connected to the power supply module and the drive module to control the transmission of the negative signal.

[0042] When the throttle handle needs to be released from the locking position, the control switch 10 is not pressed down by the rotating plate 8, so the power supply module and the drive module circuit are connected, and the negative signal of the power supply module is provided by the control switch 10 to the drive module for standby. When the brake is squeezed, the signal control switch module sends a signal to the positive signal of the power supply module to the drive module. Since the negative signal is on standby at the drive module, the drive module immediately drives the winding module to rotate, so that the adjusting member 12 drives the rotating plate 8 to rotate, and the end close to the control switch 10 moves downward, and the switch of the control switch 10 is turned on. When the clutch 29 is closed and disengaged from the locking groove 30, the pressure plate 19 drives the drive ring 15 to rotate counterclockwise by the elastic force of the fixed spring 20, thereby resetting the two through holes 17, canceling the pressure on the auxiliary ring 18 and canceling the lock on the throttle handle, and achieving a forced unlocking state. Similarly, the unlocking state can be adopted by moving the fixed block 13 upward to rotate the rotating plate 8, so that the clamping member 29 can be disengaged from the locking groove 30, and the lock on the throttle handle can be canceled by the cooperation of the fixed spring 20, the pressure plate 19 and the drive ring 15.

[0043] When the accelerator handle is unlocked, the control switch 10 is disconnected, the driver squeezes the brake, and the signal control switch module sends a signal to the positive pole of the power supply module, and the signal is transmitted to the drive module. As the drive end, because it is disconnected in the unlocked state, the signal of the negative pole of the power supply module cannot be provided to the drive module, so the drive module will not rotate, and therefore will not increase the burden on the vehicle's power. In the normal unlocked state, when the brake is squeezed, the drive module will not run and produce noise.

[0044] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
