Electronic assist trolley

Abstract

This invention discloses an electrically assisted trolley, including a frame support, a rear wheel support, a quick-release structure, and a rear wheel assembly. The rear wheel support is connected to the frame support and has one end away from the frame support. The quick-release structure is disposed at this end of the rear wheel support. The rear wheel assembly is detachably disposed on the quick-release structure and includes a motor, a rear wheel, and a connecting structure. The motor is disposed on the rear wheel and connected to the connecting structure, and the motor and the rear wheel are rotatable relative to the connecting structure. The connecting structure corresponds to the quick-release structure and has a connector. The connecting structure is detachably connected to the quick-release structure through the connector to mount the rear wheel assembly onto the rear wheel support.

Claims

1. An electric assisted stroller, comprising: One vehicle body support frame; A rear wheel bracket connected to the vehicle body bracket, the rear wheel bracket having an end away from the vehicle body bracket; a quick-release structure disposed at that end of the rear wheel bracket; and a rear wheel assembly detachably disposed on the quick-release structure, the rear wheel assembly including a motor, a rear wheel, and a connecting structure, the motor being disposed on the rear wheel and connected to the connecting structure, and the motor and the rear wheel being rotatable relative to the connecting structure; wherein the connecting structure is correspondingly disposed to the quick-release structure and has a connector, the connecting structure being detachably connected to the quick-release structure through the connector to install the rear wheel assembly onto the rear wheel bracket.

2. The electric assisted trolley as claimed in claim 1, wherein the quick-release structure includes a pressing member, a linkage member, a stop member and an elastic member, the linkage member passing through the elastic member and connecting to the pressing member, the stop member passing through the linkage member, and the two sides of the elastic member abutting against the pressing member and the stop member.

3. The electric assisted trolley as claimed in claim 2, wherein the linkage includes an arcuate groove, the connector passes through the linkage, and is correspondingly arranged with respect to the arcuate groove.

4. The electric assisted trolley as claimed in claim 3, wherein the arcuate groove includes a first arcuate portion; when the pressing member is pressed down and the linkage member is activated, the elastic member is compressed to provide an elastic restoring force, and the connecting member can pass through the first arcuate portion.

5. The electric assisted stroller as claimed in claim 4, wherein the arcuate groove further includes a second arcuate portion connected to the first arcuate portion, and the connector has an annular recess corresponding to the second arcuate portion; when the pressing member is not pressed down, the elastic restoring force causes the linkage and the pressing member to return to an initial position, thereby causing the second arcuate portion to lock the annular recess.

6. The electric assisted trolley as claimed in claim 1, wherein the motor includes a shaft passing through the connection structure.

7. The electric assisted trolley as claimed in claim 1, wherein the connecting structure further has a connecting surface abutting against the quick-release structure.

8. The electrically assisted stroller as described in claim 1, further comprising: A support frame is connected to the vehicle body frame; A drive assembly is detachably mounted on the support frame. The drive assembly is electrically connected to the motor to drive the motor to rotate.

9. The electric assisted stroller as claimed in claim 8, wherein the drive assembly includes a mounting frame, a drive unit and a battery pack, the mounting frame being detachably fixed to the support frame, and the drive unit or the battery pack being fixed to the support frame via the mounting frame.

10. The electric assisted stroller as claimed in claim 9, wherein the mounting bracket includes a pressing member that, when the pressing member is pressed down, allows the battery pack to be mounted to or detached from the mounting bracket.

11. The electrically assisted stroller as described in claim 8, further comprising: A push handle bracket is installed on the side of the support frame away from the rear wheel bracket; A travel controller is detachably mounted on the push handle bracket. The travel controller is electrically connected to the drive assembly and is used to control the rotation of the motor.

12. The electric assisted stroller as claimed in claim 11, wherein the travel controller has a first side and a second side, the first side having an acceleration button, a deceleration button, a plurality of speed indicator lights and a push button, and the second side having a forward / backward selection button.

13. The electric assisted stroller as claimed in claim 12, wherein the speed indicator lights are displayed in accordance with the number of times the acceleration button or the deceleration button is pressed.

14. The electric assisted stroller as claimed in claim 12, wherein the first side and the second side are located on opposite or adjacent sides of the travel controller.

15. The electrically assisted stroller as described in claim 1, further comprising: A front wheel is located on the side of the vehicle body support away from the rear wheel support.

16. The electrically assisted stroller as described in claim 1, further comprising: A support frame is connected to the vehicle body frame; An upper support frame is installed on the side of the support frame away from the vehicle body support; And a support frame, which is located on the side of the vehicle body support away from the rear wheel support.
