Description

Technical Field

[0001] The utility model relates to the technical field of torque controllers, in particular to a torque controller for an electric power-assisted vehicle. Background Art

[0002] Torque sensor, also known as torque sensor, torque sensor, torque sensor, torque meter, is divided into two categories: dynamic and static. Dynamic torque sensor can also be called torque sensor, torque speed sensor, non-contact torque sensor, rotational torque sensor, etc. Torque sensor is a detection of the perception of torsional torque on various rotating or non-rotating mechanical parts. The torque sensor converts the physical change of torque into an accurate electrical signal. In order to achieve the function of assisted riding and power saving in the use of electric power-assisted bicycles, a torque controller is required. When the torque sensor detects that the user is stepping on the pedal, the motor is started to achieve the function of assisting.

[0003] Patent No. CN202223184328.2 discloses a torque controller for an electric power-assisted bicycle, which realizes air circulation and filtering of the air through a transmission structure and a filter cover, and then dissipates heat inside the torque controller, so as to avoid severe heat generation causing deformation of metal parts, causing sensor failure, and failing to accurately start and shut down the motor, which cannot meet actual needs. However, during long-term operation, a lot of dust and debris will accumulate on the surface of the filter cover, which will affect the ventilation effect of the filter cover, reduce the air flow rate, and lead to poor heat dissipation effect. Manual cleaning is required in the later stage, which is time-consuming and labor-intensive. For this reason, we propose a torque controller for an electric power-assisted bicycle.

[0022] Among them, the heat dissipation component includes a fan blade 16, a first gear 12, a second gear 14 and a first transmission rod 15. The first gear 12 is detachably connected to the surface of one end of the torsion shaft 4.

The fan blade 16 is detachably connected to one end of the first transmission rod 15 relative to the second gear 14 through a bolt; the first gear 12 and the second gear 14 are both bevel gears. During the rotation of the torsion shaft 4, the first gear 12 is driven to rotate, and the second gear 14 and the fan blade 16 meshed therewith are driven to rotate, so that the fan blade 16 draws air into the shell 1, and the air passes through the connection between the torsion shaft 4 and the torque sensor 13 to dissipate the heat at the connection. The hot air is blown out of the shell 1 through the air duct, so that the torque controller 11 achieves the effect of heat dissipation and can operate continuously and stably.

[0023] Among them, the cleaning component 8 includes a mounting head 801, a fixing plate 802, an elastic connecting rod 803 and a brush plate 804. The mounting head 801 is rotatably connected to the center position of the outer wall of the dust filter cartridge 7 through a rotating connecting shaft.

By rotating the torsion shaft 4, the torque sensor 13 detects a signal and transmits it to the controller 11.

The rotation of the torsion shaft 4 drives the first gear 12 to rotate, thereby driving the second gear 14 and the fan blade 16 meshing therewith to rotate, so that the fan blade 16 draws air into the housing 1, and the air passes through the connection between the torsion shaft 4 and the torque sensor 13 to dissipate heat at the connection, and the hot air is blown out of the housing 1 through the air duct, so that The torque controller 11 can achieve the effect of heat dissipation and can operate continuously and stably. During the rotation of the fan blades 16, the second transmission rod 17 drives the mounting head 801 on the surface of the dust filter cartridge 7 and the brush plate 804 installed on one side of the mounting cartridge to rotate synchronously. The rotating brush plate 804 is used to clean the surface of the dust filter cartridge 7 to prevent dust and debris from accumulating on the surface of the dust filter cartridge 7.
