Technical Field

[0001] This application relates to a folding vehicle, and particularly to a folding vehicle that automatically interrupts a folding signal.

Background Art

[0002] Conventional folding senior cars are generally designed with a foldable structure to improve the convenience of use. By controlling a switch, the extension and retraction of an electric push rod can be controlled, and the automatic folding or unfolding of the frame can be realized. However, the method of controlling the frame to automatically fold or unfold by controlling such a switch is likely to cause accidental folding during the use of the folding vehicle due to accidentally touching the switch, and further cause the phenomenon of hurting the user, and the safety of use is not high enough.

Summary of the Invention

[0003] The object of this application is to provide a folding vehicle that automatically interrupts a folding signal, which can avoid accidental folding of the folding vehicle caused by the user accidentally touching the folding switch when riding, and improve the safety of riding.

[0004] To achieve the above object, the folding vehicle that automatically interrupts the folding signal according to this application includes a vehicle support frame, a seat body, a sensing device, a driving device, and a controller. The seat body is provided on the vehicle support frame, one end is movably provided on the vehicle support frame, the driving device is provided on the vehicle support frame and is electrically connected to the controller to drive the vehicle support frame to unfold or fold, the sensing device is provided between one end of the seat body and the vehicle support frame and is electrically connected to the controller. When the seat body bears gravity and approaches the vehicle support frame, the sensing device is triggered, and the controller interrupts the signal for controlling the driving device to operate.

[0005] Compared to conventional technology, in this invention, the seat body is movably installed on the vehicle support frame, and a sensing device is installed between the seat body and the vehicle support frame, electrically connecting the sensing device and the controller. When a user sits on the seat body, the movement of the seat body relative to the vehicle support frame drives the sensing device, triggering the latter, which then transmits a sensing signal to the controller, allowing the controller to control the drive device and stop the drive. Therefore, the folding signal of the folding car can be automatically interrupted by the sensing device, preventing the folding car from being unexpectedly folded by accidentally touching the control switch while the user is getting on, thus avoiding unexpected damage to the user. The interruption process is automatically triggered by the gravity of the user sitting on it, does not require manual intervention, and is controlled automatically, effectively improving the safety of using the folding car.

[0006] Preferably, an elastic member is provided between the vehicle support frame and the seat body, and the elastic member provides an elastic force that separates the seat body from the vehicle support frame, thereby releasing the trigger state of the sensing device. By installing the elastic member, the seat body can be automatically returned to its original position, the sensing device releases the trigger when no one is in the vehicle, and the controller can send a drive signal to activate the drive unit, thereby enabling the folding of the vehicle support frame.

[0007] Preferably, the vehicle support frame has one end pivotally attached to the rear end of the seat body and a groove at the other end, and the front end of the seat body is slidably mounted in the groove by a slide shaft, and when a load is applied to the seat body, the slide shaft slides from one end of the groove towards the vehicle support frame to the other end. By providing the groove, the seat body not only moves relative to the vehicle support frame but also does not detach from the vehicle support frame, and furthermore, it provides power to trigger or release the sensing device, thereby achieving the purpose of automatic control.

[0008] Specifically, the sensing device includes a sensor and a first trigger, the sensor being mounted on the vehicle support frame and electrically connected to the controller, and the first trigger being connected to the front end of the seat body and approaching the sensor as the seat body moves to trigger the sensor.

By providing the slide shaft in the elongated hole, the first trigger can move in conjunction with the seat body and move linearly along the direction of the first support rod, which makes the movement of the first trigger more stable and is advantageous for stable contact with the sensor.

[0010] Specifically, the sensing device further includes a second trigger, the second trigger being fixed within the first support rod, and the sensor being fixed to the second trigger.

[0011] Specifically, the vehicle support frame includes a first support rod, a second support rod, and a third support rod, the first support rod and the second support rod are installed so as to intersect, their middle portions are pivotally connected to each other, the upper end of the second support rod is pivotally connected to the lower end of the third support rod, the upper end of the third support rod is pivotally connected to the rear end of the seat body, and the groove body is installed on the upper end of the first support rod.

The seat body 2 is provided on the vehicle support frame 1, and one end is movably provided on the vehicle support frame 1. Specifically, the rear end of the seat body 2 is pivotally attached to one end of the vehicle support frame 1, so that the seat body 2 can swing at a certain angle relative to the vehicle support frame 1, and the front end is connected to the other end of the vehicle support frame 1, so that it can move toward or away from that end of the vehicle support frame 1. The drive device 4 is provided on the vehicle support frame 1 and electrically connected to the controller 5 to drive the vehicle support frame 1 to unfold or fold. The drive device 4 is a linear telescopic actuator, and may be, for example, an electric push rod. The sensing device 3 is provided between one end of the seat body 2 and the vehicle support frame 1 and is electrically connected to the controller 5. When the seat body 2 approaches the vehicle support frame 1 under the influence of gravity, it triggers the sensing device 3, interrupting the signal that controls the controller 5 to operate the drive unit 4.

[0018] Referring further to Figures 3 and 4, an elastic member 6 is provided between the vehicle support frame 1 and the seat body 2. The elastic member 6 provides an elastic force that separates the seat body 2 from the vehicle support frame 1. When the seat body 2 is unloaded, the elastic force of the elastic member 6 is sufficient to push the seat body 2 away from the vehicle support frame 1, thereby releasing the trigger state of the sensing device 3. The elastic member 6 is a compression spring. By providing the elastic member 6, the seat body 2 can be automatically returned to its original position, the sensing device 3 can release the trigger when no one is sitting on it, and the controller 5 can send a drive signal to activate the drive device 4, thereby enabling the folding of the vehicle support frame 1.

[0019] Referring further to Figures 3-5, a groove 1a is provided at the end of the vehicle support frame 1 adjacent to the front end of the seat body 2, a connecting lug 21 is provided on the lower side of the front end of the seat body 2, a lateral slide shaft 22 is provided on the connecting lug 21, the slide shaft 22 is slidably drilled in the groove 1a, and when a load is applied to the seat body 2, the slide shaft 22 slides from one end of the groove 1a to the other end of the groove 1a in a direction approaching the vehicle support frame 1. By providing the groove 1a, the seat body 2 not only moves relative to the vehicle support frame 1, but also does not detach from the vehicle support frame 1, and furthermore, it provides power to trigger or release the sensing device 3, thereby achieving the purpose of automatic control. In this embodiment, the groove 1a has a bent structure. Specifically, the groove body 1a includes a first groove body 11a and a second groove body 12a. The first groove body 11a extends from its upper end toward the front and downward of the folding wheel 100 and communicates with one end of the second groove body 12a, while the second groove body 12a extends toward the rear and downward of the folding wheel 100. The widths of the first groove body 11a and the second groove body 12a are greater than the diameter of the slide shaft 22, and the slide shaft 22 is installed in the first groove body 11a or the second groove body 12a with a gap between them. By installing the groove body 1a in a bent structure, during the folding process, the slide shaft 22 slides into the first groove body 11a, and the side walls of the first groove body 11a prevent the slide shaft 22 from moving along other directions, further achieving self-locking, preventing the seat body 2 from being pushed down by an external force during the folding process and triggering the sensing device 3, thereby improving reliability of use. In other embodiments, the groove 1a may have an arc-shaped structure.

[0020] Referring further to Figures 4 and 5, the sensing device 3 includes a sensor 31, a first trigger 32, and a second trigger 33. The sensor 31 is provided on the vehicle support frame 1 and electrically connected to the controller 5. The first trigger 32 is connected to the underside of the front end of the seat body 2 and, as the seat body 2 moves, approaches the sensor 31 to trigger it, or moves away from the sensor 31 to de-trigger it. By providing the sensor 31 on the vehicle support frame 1, it moves in accordance with the seat body 2 using the first trigger 32, and the first trigger 32 can trigger or de-trigger the sensor 31. Specifically, the second trigger 33 is fixed within the first support rod 13, and the sensor 31 is fixed within the first support rod 13 by being fixed to the second trigger 33. More specifically, the first trigger 32 is slidably provided within the first support rod 13 of the vehicle support frame 1, and an elongated hole 32a is provided within the first trigger 32, with the extension direction of the elongated hole 32a being perpendicular to the extension direction of the length of the first support rod 13. The slide shaft 22 slidably passes through the elongated hole 32a. By providing the slide shaft 22 in the elongated hole 32a, the first trigger 32 can not only move in conjunction with the movement of the seat body 2, but also move linearly along the direction of the first support rod 13, which is advantageous for stabilizing the movement of the first trigger 32 and ensuring stable contact with the sensor 31. A leg portion 321 is provided on the side of the first trigger 32 facing the sensor 31, and the leg portion 321 can be used to contact the sensor 31 and trigger it.Further, the elastic member 6 is provided between the first trigger 32 and the second trigger 33. Specifically, a first positioning hole 322 is provided on the side of the first trigger 32 facing the second trigger 33, and a second positioning hole 331 is provided on the side of the second trigger 33 facing the first trigger 32.

[0021] Also, as shown in FIGS. 2 and 3, the vehicle support frame 1 includes a front vehicle body rod 11, a rear vehicle body rod 12, a first support rod 13, a second support rod 14, a third support rod 15, a tie rod 16, a front wheel support frame 17, a rear wheel support frame 18, a front wheel 19, and a rear wheel 20. The rear end of the front vehicle body rod 11 is pivotally attached to the front end of the rear vehicle body rod 12, the front end of the front vehicle body rod 11 is pivotally attached to the front wheel support frame 17, the front wheel 19 is provided on the front wheel support frame 17, the rear end of the rear vehicle body rod 12 is pivotally attached to the rear wheel support frame 18, the rear wheel 20 is provided on the rear wheel support frame 18, and the lower end of the first support rod 13 is connected to the rear wheel support frame 18. The second support rod 14 is installed so as to intersect the first support rod 13, and the middle parts thereof are pivotally attached to each other. The lower end of the second support rod 14 is pivotally attached to the rear end of the front vehicle body rod 11. An engaging convex portion 111 is provided on one of the end faces of the rear end of the front vehicle body rod 11 and the end face of the lower end of the second support rod 14, and an engaging concave portion 141 is provided on the other. The engaging convex portion 111 and the engaging concave portion 141 are engaged and connected to each other during deployment to lock the vehicle support frame 1. The upper end of the second support rod 14 is pivotally attached to the lower end of the third support rod 15, the upper end of the third support rod 15 is pivotally attached to the rear end of the seat body 2, and the groove body 1a is provided at the upper end of the first support rod 13. The front end of the tie rod 16 is pivotally attached to the front wheel support frame 17, and the rear end of the tie rod 16 is pivotally attached to the rear vehicle body rod 12.

[0022] Based on the above, the operating principle of the folding vehicle 100 that automatically interrupts the folding signal of the present invention will be described in detail below with reference to Figures 2, 6, and 7.

[0023] When the folding vehicle 100 is fully unfolded and unloaded, the slide shaft 22 is positioned at the uppermost end of the first groove 11a, at which point the first trigger 32 is separated from the sensor 31, and the sensor 31 is in the trigger-release state. At this time, the signal connection between the controller 5 and the drive unit 4 is on, and the user presses the control switch to send a signal to the controller 5 via the control switch, which controls the controller 5 to activate the drive unit 4, and the drive unit 4 can be driven to unfold or fold the vehicle support frame 1.

[0024] When the folding cart 100 is fully deployed and the user gets on it, the seat body 2 bears the load. At this time, the seat body 2 moves downward against the elastic force of the elastic member 6, and the slide shaft 22 slides from the first groove body 11a to the lower end of the second groove body 12a. At the same time, the slide shaft 22 pushes the first trigger 32 to move, and slides the first trigger 32 along the extending direction of the first support rod 13 closer to the sensor 31, and finally contacts the sensor 31, and further triggers the sensor 31. The sensor 31 transmits a signal to the controller 5. In this case, after receiving the signal, the controller 5 can interrupt the signal connected to the driving device 4, and can also interrupt the signal connected to the control switch between the controller 5 and the control switch. Even if the control switch is pressed, the controller 5 cannot control the activation of the driving device 4. In this case, the driving device 4 will not accidentally fold the vehicle support frame 1, and the safety is greatly improved. When the user gets off the vehicle, the seat body 2 is in a non-load state, and the elastic member 6 elastically pushes the seat body 2 to return, separating the seat body 2 from the vehicle support frame 1. At this time, the seat body 2 interlocks with the first trigger 32 to separate from the sensor 31, and the triggered state of the sensor 31 is released. Therefore, the controller 5 can restore the signal connected to the driving device 4, or the controller 5 can restore the signal connected to the control switch, and the controller 5 can control the driving device 4 again to activate the folding of the vehicle support frame 1.

[0025] Compared to conventional technology, this invention provides a seat body 2 that is movably mounted on a vehicle support frame 1, a sensing device 3 between the seat body 2 and the vehicle support frame 1, and an electrically connected sensing device 3 and a controller 5. When a user gets on the seat body 2, the movement of the seat body 2 relative to the vehicle support frame 1 drives the sensing device 3, which is triggered, transmitting a sensing signal to the controller 5, and the controller 5 controls the drive device 4 to stop the drive. Therefore, the sensing device 3 can automatically interrupt the folding signal of the folding car 100, preventing the folding car 100 from unexpectedly folding due to the user accidentally touching the control switch during the process of getting on, thus avoiding unexpected damage to the user due to unexpected folding. The interruption process is automatically triggered by the gravity of the user getting on, does not require manual intervention, and is controlled automatically, effectively improving the safety of using the folding car 100.
