The present embodiment provides a power assist apparatus for a vehicle, which is described in detail below with reference to fig. 1 to 4.

As shown in fig. 1, a power assisting device 110 provided in an embodiment of the present application includes: the first clamping seat 110 and the second clamping seat 120 detachably connected with the first clamping seat 110, a first clamping groove 111 matched with a vehicle beam of the vehicle is arranged at the connecting side of the first clamping seat 110 and the second clamping seat 120, and a second clamping groove 121 opposite to the first clamping groove 111 and matched with the vehicle beam of the vehicle is arranged on the second clamping seat 120; the second card holder 120 is provided with a wheel set 130, and the power assisting device 110 further includes a motor connected to the wheel set 130, and a charging pedal 140 electrically connected to the motor; when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 is in contact with a wheel body of the vehicle; the motor can drive the wheel body of the vehicle to rotate through the wheel set 130; when the power assisting device 110 is located on a road surface, the plane on which the charging pedal 140 is located matches the road surface, and the motor can drive the wheel set 130 to rotate on the road surface.

In the present embodiment, the vehicle refers to an apparatus having a running function. For example, the vehicle may be an automobile, a scooter, or a bicycle 200. Fig. 2 exemplarily shows that the vehicle is a bicycle 200.

The vehicle beam in this embodiment is used for supporting a wheel body of a vehicle, and may be a main beam or a sub beam. The structure and shape of the vehicle beam can be set according to actual needs. Fig. 2 exemplarily shows that the vehicle is a bicycle 200, where the beam is a main beam of the bicycle 200, where the main beam is a cylindrical tube.

In this embodiment, a first clamping groove 111 matched with a beam of the vehicle is disposed on a connection side of the first clamping seat 110 and the second clamping seat 120. The shape of the first engaging groove 111 may be set according to actual needs, as long as it is convenient to engage the vehicle beam. For example, when the vehicle beam is a cylindrical pipe, the cross-sectional shape of the first engaging groove 111 may be rectangular or trapezoidal.

The second clamping seat 120 in this embodiment is provided with a second clamping groove 121 opposite to the first clamping groove 111 and matched with the vehicle beam of the vehicle, and is used for being matched with the first clamping groove 111 to clamp the power assisting device 110 on the vehicle beam of the vehicle. The shape of the second card slot 121 may be the same as or different from the shape of the first card slot 111. The shape of the second engaging groove 121 can be set according to actual needs, as long as it is convenient to engage the vehicle beam of the vehicle. For example, when the vehicle beam is a cylindrical pipe, the cross-sectional shapes of the first engaging groove 111 and the second engaging groove 121 may be both rectangular or trapezoidal. Fig. 1 exemplarily shows that, when the vehicle body member is a cylindrical pipe body, the cross-sectional shape of the first engaging groove 111 and the cross-sectional shape of the second engaging groove 121 are both circular.

The motor in this embodiment is used to provide driving force for the wheel set 130, and the motor here may be an inner rotor motor or an outer rotor motor. When the motor is an inner rotor motor, the first end of the rotating shaft of the motor is used as an output end to be connected with the power input mechanism of the wheel set 130; the power input mechanism here may be a fixed shaft connected to the wheel set 130. When the motor is an outer rotor motor, the outer side of the outer rotor of the motor can be used as an output end to be connected with the power input mechanism of the wheel set 130; the power input means here may be a hub connected to the rotor. For example, as shown in fig. 3 and 4, the motor may be an in-wheel motor 150, and the wheel set 130 is disposed directly outside the in-wheel motor 150. Optionally, a planetary reducer connected to the in-wheel motor 150 is disposed in the in-wheel motor 150, a gear knob 151 connected to the planetary reducer is further disposed on a side surface of the in-wheel motor 150, and a transmission ratio of the planetary reducer can be changed by rotating the gear knob 151, so as to change a rotation speed and a torque of the in-wheel motor 150, so as to respectively adapt to a high-speed low-torque performance when the power assisting device 110 provides power for the vehicle and a low-speed high-torque performance when the coasting function is implemented. Of course, the planetary reducer can be replaced by a combination of a primary gear and a secondary gear; when the in-wheel motor 150 is engaged with the primary gear, the in-wheel motor 150 provides high speed low torque performance; when the in-wheel motor 150 is engaged with the secondary gear, the in-wheel motor 150 provides low speed high torque performance. It is understood that the hub motor 150 herein can also have high-speed low-torque performance and low-speed high-torque performance by changing the parallel-serial connection form of the motor windings.

The charging pedal 140 in this embodiment is used to provide electric energy for the motor, and the setting position of the charging pedal 140 may be set according to actual needs, as long as when the power assisting device 110 is located on a road surface, the plane on which the charging pedal 140 is located matches with the road surface. The plane in which the charging pedal 140 is located matches the road surface so that a person located on the charging pedal 140 can slide through the booster 110. Here, the charging pedal 140 may be disposed on the first card socket 110, the second card socket 120, or both the first card socket 110 and the second card socket 120. Optionally, the top side of the charging pedal 140 may be provided with a slip-preventing structure. The anti-slip structure may be a protrusion structure provided on the top side of the charging pedal 140, or may be an anti-slip layer coated on the top side of the charging pedal 140.

In this embodiment, the first card holder 110 is detachably connected to the second card holder 120, and the connection manner between the first card holder 110 and the second card holder 120 is not limited, for example, the first card holder 110 and the second card holder 120 may be detachably connected by bolts or by fasteners.

Illustratively, as shown in fig. 1, a first end of the connection side of the first cartridge 110 and the second cartridge 120 and a first end of the connection side of the second cartridge 120 and the first cartridge 110 are hinged; a groove 123 is formed at a second end of the connecting side of the second card holder 120 and the first card holder 110, and a snap ring 114 matched with the groove 123 is arranged at a second end of the connecting side of the first card holder 110 and the second card holder 120; the snap ring 114 can rotate to be clamped in the groove 123 through the second end of the connecting side of the first clamping seat 110 and the second clamping seat 120, and can rotate and be far away from the groove 123 through the second end of the connecting side of the first clamping seat 110 and the second clamping seat 120.

In some optional implementations of this example, in order to conveniently clamp the snap ring 114 in the groove 123, as shown in fig. 1, a lock rod 115 is further disposed at a second end of a connection side of the first cassette 110 and the second cassette 120, a first end of the lock rod 115 is hinged to a second end of the connection side of the first cassette 110 and the second cassette 120, and a second end of the lock rod 115 is hinged to the snap ring 114; when the clamping ring 114 is clamped in the groove 123, the locking rod 115 can rotate around the second end of the connecting side of the first clamping seat 110 and the second clamping seat 120 along a first direction to enable the clamping ring 114 to be clamped in the groove 123, and can rotate around the second end of the connecting side of the first clamping seat 110 and the second clamping seat 120 along a second direction to enable the clamping ring 114 clamped in the groove 123 to be separated from the groove 123; wherein the first direction and the second direction are opposite.

In use, as shown in fig. 1, the first clamping seat 110 and the second clamping seat 120 are detachably connected together, so as to ensure that the shape of the power assisting device 110 is fixed. When the boosting device 110 needs to provide boosting force to the vehicle, as shown in fig. 10, the first clamping seat 110 may be rotated until the second end of the first clamping seat 110 is separated from the second end of the first clamping seat 110, and the boosting device 110 is placed at a vehicle beam of the vehicle, so that the vehicle beam is located between the first clamping groove 111 and the second clamping groove 121; as shown in fig. 8, rotating the first cartridge 110 to bring the second end of the first cartridge 110 into engagement with the second end of the second cartridge 120; as shown in fig. 9, the locking bar 115 is rotated in the second direction to clamp the snap ring 114 in the groove 123; as shown in fig. 1, rotating the locking lever 115 in a first direction causes the snap ring 114 to snap into the groove 123. When the power assisting device 110 needs to be removed from the vehicle, as shown in fig. 8, the lock rod 115 is rotated in the second direction to disengage the snap ring 114 clamped in the groove 123 from the groove 123; as shown in fig. 10, the power assisting device 110 can be removed by opening the first clamping seat 110 and the second clamping seat 120. It can be understood that when the power assisting device 110 is used as a sliding device, the first clamping seat 110 and the second clamping seat 120 are connected together.

The second clamping seat 120 in this embodiment is provided with a wheel set 130, where the wheel set 130 may include one wheel body, or may include a plurality of wheel bodies, and fig. 2 exemplarily shows that the wheel set 130 includes one wheel body. The wheel set 130 is used for contacting with a wheel body of the vehicle when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, so that the motor drives the wheel set 130 to rotate, and the wheel body of the vehicle is driven to rotate, thereby providing driving force for the vehicle to run; when the power assisting device 110 is located on a road surface, the plane on which the charging pedal 140 is located matches the road surface, and the motor can drive the wheel set 130 to rotate on the road surface, so that a human body located on the charging pedal 140 can slide on the road surface through the power assisting device 110. The position of the wheel set 130 corresponds to the position of the charging pedal 140, and the position of the wheel set 130 can be set according to actual needs, as long as the power assisting device 110 can realize both the power assisting function of the vehicle and the road surface sliding function. Two alternative setting positions of the wheel set 130 and the charge pedal 140 are listed below by way of example.

For example, as shown in fig. 1 and 5, a wheel set 130 and a charging pedal 140 are arranged at a first optional position, a first clamping mechanism is arranged at the bottom side of the charging pedal 140, a second clamping mechanism 112 matched with the first clamping mechanism is arranged at the first clamping seat 110, the charging pedal 140 is connected with the first clamping seat 110 through the first clamping mechanism and the second clamping mechanism 112, and the wheel set 130 is arranged at the side surface of the second clamping seat 120 opposite to the charging pedal 140. Here, the charging pedal 140 and the wheel set 130 are disposed on opposite sides of the power assisting device 110, so that when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 is in contact with a wheel body of the vehicle; when the boosting device 110 is located on the road surface, the plane on which the charging pedal 140 is located matches the road surface.

The structure of the first clamping mechanism and the structure of the second clamping mechanism 112 can be set according to actual needs as long as the connection of the charging pedal 140 and the first card holder 110 can be realized. For example, the first clamping mechanism may be a through hole disposed at the bottom side of the charging pedal 140, and correspondingly, the second clamping mechanism 112 may be a threaded hole disposed on the first card socket 110 and matched with the through hole, and a screw matched with the threaded hole is used to pass through the through hole at the bottom side of the charging pedal 140 and be connected with the threaded hole on the first card socket 110, so as to connect the charging pedal 140 and the first card socket 110. For another example, the first clamping mechanism is a clamping slot with a T-shaped cross section, the second clamping mechanism 112 is a first clamping hook with a T-shaped cross section, and the first clamping hook is inserted into the clamping slot, so that the connection between the charging pedal 140 and the first clamping seat 110 is realized. It can be understood that the cross-sectional shape of the locking groove may also be triangular or trapezoidal, and correspondingly, the cross-sectional shape of the first hook may also be triangular or trapezoidal.

For another example, in a second optional arrangement position of the wheel set 130 and the charging pedal 140, a first clamping mechanism is arranged on the bottom side of the charging pedal 140; a second clamping mechanism 112 matched with the first clamping mechanism is arranged on the opposite side of the connecting side of the first card holder 110 and the second card holder 120, and a third clamping mechanism 113 matched with the first clamping mechanism is further arranged on the adjacent side of the connecting side of the first card holder 110 and the second card holder 120; the wheel set 130 protrudes from the side surface of the second clamping seat 120 opposite to the connecting side of the first clamping seat 110, and protrudes from the side surface of the second clamping seat 120 opposite to the second clamping mechanism 112; as shown in fig. 6 and 2, when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the charging pedal 140 is connected to the first clamping seat 110 through the first clamping mechanism and the second clamping mechanism 112; the part of the wheel set 130, which protrudes out of the side surface opposite to the side where the second clamping seat 120 is connected with the first clamping seat 110, can be in contact with the wheel body of the vehicle, and the motor can drive the wheel body of the vehicle to rotate through the wheel set 130; as shown in fig. 3, when the power assisting device 110 is located on a road surface, the charging pedal 140 is connected to the first clamping seat 110 through the first clamping mechanism and the third clamping mechanism 113; the part of the wheel set 130 protruding out of the side of the second clamping seat 120 opposite to the second clamping mechanism 112 contacts with the road surface, and the motor can drive the wheel set 130 to rotate on the road surface.

Here, the structure of the first chucking mechanism, the structure of the second chucking mechanism 112, and the structure of the third chucking mechanism 113 may be set as necessary. For example, the first clamping mechanism may be a through hole disposed at the bottom side of the charging pedal 140, and correspondingly, the second clamping mechanism 112 may be a threaded hole disposed at the opposite side of the connection side of the first card holder 110 and the second card holder 120 and matched with the through hole; the third clamping mechanism 113 may be a threaded hole disposed at a side adjacent to the connection side of the first clamping base 110 and the second clamping base 120 and matched with the through hole; when the power assisting device 110 is clamped on a vehicle beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, a screw matched with a threaded hole is used to penetrate through a through hole on the bottom side of the charging pedal 140 to be connected with a threaded hole on the opposite side of the connecting side of the first clamping seat 110 and the second clamping seat 120, so that the connection between the charging pedal 140 and the first clamping seat 110 is realized; when the power assisting device 110 is located on a road surface, a screw matched with the threaded hole penetrates through a through hole in the bottom side of the charging pedal 140 to be connected with a threaded hole in the adjacent side of the connection side of the first clamping seat 110 and the second clamping seat 120, so that the connection between the charging pedal 140 and the first clamping seat 110 is realized. For another example, the first clamping mechanism is a clamping groove with a T-shaped cross section, the second clamping mechanism 112 is a first hook with a T-shaped cross section, which is matched with the clamping groove, and the third clamping mechanism 113 is a second hook with a T-shaped cross section, which is matched with the clamping groove, when the power assisting device 110 is clamped on a vehicle beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the first hook is inserted into the clamping groove, so that the connection between the charging pedal 140 and the first clamping seat 110 is realized; when the power assisting device 110 is located on the road surface, the second hook is inserted into the slot, so that the connection between the charging pedal 140 and the first card seat 110 is realized. It can be understood that the cross-sectional shape of the locking groove may be triangular or trapezoidal, and correspondingly, the cross-sectional shape of the first hook and the cross-sectional shape of the second hook may be both triangular or trapezoidal.

Optionally, as shown in fig. 6, in a second optional setting position of the wheel set 130 and the charging pedal 140, a fourth clamping mechanism 122 matched with the first clamping mechanism may be provided at a position of the second clamping seat 120 corresponding to the third clamping mechanism 113; when the power assisting device 110 is located on a road surface, the charging pedal 140 is connected to the first card holder 110 through the first clamping mechanism and the third clamping mechanism 113, and is connected to the second card holder 120 through the first clamping mechanism and the fourth clamping mechanism. Here, by simultaneously connecting the charging pedal 140 to the first clamping seat 110 and the second clamping seat 120, the power assisting device 110 can slide on the road more reliably.

The fourth chucking mechanism 122 corresponds to the third chucking mechanism 113 and may be provided as needed. For example, when the first clamping mechanism is a through hole disposed at the bottom side of the charging pedal 140, correspondingly, the fourth clamping mechanism 122 may be a threaded hole disposed at a position corresponding to the second clamping mechanism 120 and the third clamping mechanism 113 (a threaded hole matching with the through hole at the adjacent side of the connection side of the first clamping base 110 and the second clamping base 120), and matching with the through hole at the bottom side of the charging pedal 140; when the power assisting device 110 is located on a road surface, a screw matched with a threaded hole penetrates through a through hole in the bottom side of the charging pedal 140 to be connected with a threaded hole in the adjacent side of the connecting side of the first clamping seat 110 and the second clamping seat 120, and meanwhile, a screw matched with a threaded hole penetrates through a through hole in the bottom side of the charging pedal 140 to be connected with a threaded hole in the second clamping seat 120; the connection of the charging pedal 140 with the first card socket 110 and the second card socket 120 is realized. For another example, when the first clamping mechanism is a slot with a T-shaped cross section, correspondingly, the fourth clamping mechanism 122 is a third hook with a T-shaped cross section, which is matched with the slot; when the power assisting device 110 is located on the road surface, the second hook and the third hook are inserted into the clamping grooves, so that the charging pedal 140 is connected with the first clamping seat 110 and the second clamping seat 120 at the same time. It can be understood that the cross-sectional shape of the locking groove may be triangular or trapezoidal, and correspondingly, the cross-sectional shape of the first hook, the cross-sectional shape of the second hook and the cross-sectional shape of the third hook may be triangular or trapezoidal.

In some optional implementations of this embodiment, the boosting device 110 further includes an adjusting mechanism 160, and the wheel set 130 is connected to the second clamping seat 120 through the adjusting mechanism 160; when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 can move along a wheel body of the vehicle through the adjusting mechanism 160 to contact with the wheel body of the vehicle. When the power assisting device 110 is clamped on the beams of different vehicles, the distance between the wheel set 130 and the wheel body of the vehicle is different, and the adjusting mechanism 160 can make the wheel set 130 contact with the wheel body of the vehicle, so that the power assisting device 110 can adapt to different vehicles and provide power assistance for different vehicles. Of course, the power assisting device 110 may not include the adjusting mechanism 160, and in this case, the power assisting device 110 needs to be arranged for a corresponding type of vehicle, and when the power assisting device 110 is mounted to a beam of the vehicle, the wheel set 130 is in contact with a wheel body of the vehicle, so that the power assisting device 110 provides power assistance for the corresponding type of vehicle.

In this implementation, the adjustment mechanism 160 is used to adjust the distance of the wheel set 130 from the wheel of the vehicle. The structure of the adjusting mechanism 160 may be set according to actual requirements, as long as it can move along the direction of the wheel body of the vehicle to make the wheel set 130 contact with the wheel body of the vehicle. Two implementations of the adjustment mechanism 160 are listed below by way of example.

For example, in a first implementation manner of the adjusting mechanism 160, the adjusting mechanism 160 includes a turbine rotatably disposed on the second clamping seat 120 and a movable shaft, a first end of the shaft is connected to the wheel set 130, and the wheel set 130 is capable of rotating at the first end of the shaft, a second end of the shaft is provided with a worm matching with the turbine, and when the power assisting device 110 is clamped on the beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 is capable of moving along the direction of the wheel body of the vehicle to contact with the wheel body of the vehicle through the turbine and the worm.

For another example, as shown in fig. 7, in a second implementation of the adjusting mechanism 160, the adjusting mechanism 160 includes: a first slide way 161 and a second slide way which are arranged on the second clamping seat 120, wherein the sliding direction of the first slide way 161 and the sliding direction of the second slide way are respectively consistent with the direction between the wheel set 130 and the wheel body of the vehicle; a first end of a shaft of the wheel set 130 is inserted into the first slideway 161, a first telescopic mechanism abutting against the first end of the shaft of the wheel set 130 is further arranged in the first slideway 161, a second end of the shaft of the wheel set 130 is inserted into the second slideway, and a second telescopic mechanism abutting against the second end of the shaft of the wheel set 130 is further arranged in the second slideway; wherein the first and second telescoping mechanisms are both in a compressed state; when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 can move to contact with a wheel body of the vehicle along a direction of the wheel body of the vehicle through the first telescopic mechanism and the second telescopic mechanism.

Here, the direction between the wheel set 130 and the wheel of the vehicle refers to a direction in which the wheel set 130 may contact the wheel of the vehicle after moving.

Here, two ends of the shaft of the wheel set 130 are respectively inserted into the first slide track 161 and the second slide track, the first end of the shaft of the wheel set 130 abuts against the first telescopic mechanism, the second end of the shaft of the wheel set 130 abuts against the second telescopic mechanism, and because the first telescopic mechanism and the second telescopic mechanism are both in a pressed state, the two ends of the shaft of the wheel set 130 can move to contact with the wheel body of the vehicle along the direction of the wheel body of the vehicle under the pressure action of the first telescopic mechanism and the second telescopic mechanism.

The first telescopic mechanism may be disposed according to actual requirements, as long as the first end of the shaft of the wheel set 130 can be pushed to slide in the first slideway 161. For example, the first telescopic mechanism may be a gas spring, or may be an elastic structure having a telescopic function.

The structure of the second telescopic mechanism and the structure of the first telescopic mechanism may be the same or different. When the structure of second telescopic machanism is the same with the structure of first telescopic machanism, processing is convenient, and later maintenance is convenient.

For example, the first telescopic mechanism includes a first spring 162 disposed at the bottom of the first slide track 161, a first slide block 163 abutting against the first spring 162, an opposite side of the first slide block 163 abutting against the first spring 162 abuts against a first end of the shaft of the wheel set 130, and the first spring 162 is in a compressed state; the second telescopic mechanism comprises a second spring arranged at the bottom of the second slide way and a second sliding block abutted against the second spring, the opposite side of the second sliding block abutted against the second spring is abutted against the second end of the shaft of the wheel set 130, and the second spring is in a compressed state; when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 can move to contact with a wheel body of the vehicle along a direction of the wheel body of the vehicle through the first slider 163 and the second slider.

In the embodiment of the present application, when the power assisting device 110 is clamped on a beam of the vehicle through the first clamping groove 111 and the second clamping groove 121, the wheel set 130 is in contact with a wheel body of the vehicle; the motor can drive the wheel body of the vehicle to rotate through the wheel set 130, so as to provide driving force for the vehicle and realize the power-assisted function; when the power assisting device 110 is located on the road surface, the plane where the charging pedal 140 is located is matched with the road surface, and the motor can drive the wheel set 130 to rotate on the road surface, so that the sliding function is realized. The power assisting device 110 of the embodiment can provide driving force for the vehicle and can also be used as a sliding device for sliding, so that the problems of single function and poor adaptability of the power assisting device 110 are solved.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
