[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] See also Figure 1-Figure 17 The automatic reset energy storage rebound device includes a rebound bracket, an elastic element 1 and a push element 2, and is characterized in that: the rebound bracket is provided with a heart-shaped slide groove 3, a control circuit board 19, and a power supply element 20 and a reset drive component electrically connected to the control circuit board 19 respectively; the elastic element 1 elastically acts on the rebound bracket and the push element 2 respectively; the push element 2 is drivingly connected to the reset drive component, and a movable part 4 is arranged on it; the push element 2 slides on the rebound bracket through the elastic expansion and contraction of the elastic element 1, and drives the movable part 4 to slide and / or position along the track of the heart-shaped slide groove 3 in a sequential direction when sliding.

When the push element 2 elastically extends and opens on the rebound bracket, the control circuit board 19 will control the reset drive assembly to drive the push element 2 to automatically reset and slide in, and position and close on the rebound bracket, so as to effectively avoid the problem of the push element 2 in the prior art that must be manually closed and reset after being pressed to open, so that the push element 2 can automatically close and reset after the user presses to open, thereby reducing the user's operation and improving the user's experience.

[0046] Moreover, the reset drive assembly is reset to the initial position under the control of the control circuit board 19 when the push element 2 is closed, so as to wait for the next round of work, thereby avoiding the problem that the reset drive assembly cannot be automatically reset after work, or needs to be reset manually, causing the push element 2 to be unable to elastically extend and open, or the user's operation is cumbersome, which not only ensures the normal use of the product, but also makes the use of the product more intelligent, further improving the user's experience

[0047] Specifically, the reset drive assembly includes a motor 30, a transmission wheel 31, a transmission rod 32 and a driving member 33; the motor 30 is drivingly connected to the transmission wheel 31, and the two are integrally modularly arranged; the transmission wheel 31 is drivingly connected to the transmission rod 32, and the transmission rod 32 is drivingly connected to the driving member 33; the driving member 33 linearly reciprocates on the rebound bracket through the cooperation of the motor 30, the transmission wheel 31 and the transmission rod 32.

[0048] The reset drive assembly also includes an assembly shell 34; the motor 30 and the transmission wheel 31 are respectively arranged in the assembly shell 34, and an integrated modular setting is formed by the assembly shell 34. The integrated modular setting of the motor 30 and the transmission wheel 31 has a simple structure and a small volume, and will not occupy too much rebound bracket space after assembly.

[0049] The transmission wheel 31 is provided with a transmission part 35 ; the end of the transmission rod 32 is provided with a transmission matching part 36 , and is transmission-connected with the transmission part 35 of the transmission wheel 31 via the transmission matching part 36 .

[0050] The transmission rod 32 is rotated on the rebound bracket through the cooperation of the motor 30 and the transmission wheel 31, and a threaded portion 37 is also provided on the rebound bracket; a hole portion 38 is provided on the driving member 33, and a spiral portion 39 is provided in the hole portion 38; the driving member 33 is sleeved on the transmission rod 32 through the hole portion 38, and is driven and connected by the spiral portion 39 and the threaded portion 37 in an engaging manner. The driving member 33 slides linearly back and forth on the rebound bracket through the rotation of the transmission rod 32.

[0051] The driving member 33 is provided with a driving portion 40 ; the pushing element 2 is provided with a driving matching portion 41 .

[0052] When the push element 2 elastically extends and opens when the rebound bracket, the driving member 33 acts on the driving matching portion 41 through the driving portion 40, and drives the push element 2 to automatically return to its original position and slide in, and to be positioned and closed on the rebound bracket.

[0053] The control circuit board 19 is electrically connected to the power supply element 20 and the motor 30 through power lines 42 , and a switch 43 is also disposed thereon; the pushing element 2 is provided with a touch portion 44 .

[0054] The pushing element 2 acts on the switch 43 through the touch portion 44 when the rebound bracket elastically extends and opens to a certain position; the control circuit board 19 controls the motor 30 to drive the pushing element 2 to automatically return to its original position and slide in through the cooperation of the transmission wheel 31, the transmission rod 32, and the driving member 33, and to position and close on the rebound bracket through the touch delay of the switch 43 or the continued extension and opening of the pushing element 2.

[0055] The heart-shaped slide groove 3 is at least provided with a first limited sliding area 8 , a first conversion position 9 , an inclined guide area 10 , and a heart-shaped stay area 11 ; the movable member 4 is provided with a sliding portion 7 .

[0056] like Figure 11-13 As shown, when the pushing element 2 slides into the rebound bracket, it drives the movable part 4 to slide in the direction of the heart-shaped slide groove 3. When the movable part 4 slides to a certain position, the sliding part 7 is limited to slide into the first limited sliding area 8. When the first limited sliding area 8 slides to a certain position, the sliding part 7 slides along the trajectory of the first conversion position 9, and is limited to slide to the inclined guide area 10 by the elastic element 1, and finally slides into and stays in the heart-shaped stay area 11 through the inclined guiding effect of the inclined guide area 10.

[0057] When the sliding portion 7 stays in the heart-shaped stay area 11, the push element 2 is positioned and closed on the rebound bracket, and the touch portion 44 and the switch 43, and the drive portion 40 and the drive matching portion 41 are separated from each other and form a certain distance.

[0058] The heart-shaped slide groove 3 is also provided with a second conversion position 12 and a second limit sliding area 13 .

[0059] like Figure 13-Figure 17 As shown, when the sliding portion 7 stays in the heart-shaped staying area 11 and the pushing element 2 is pressed and slid relative to the rebound bracket, the sliding portion 7 is driven by the pushing element 2 to slide out of the heart-shaped staying area 11, and slides along the trajectory of the second conversion position 12, and is limited to slide to the second limited sliding area 13 by the elastic element 1.

[0060] When the sliding portion 7 slides to the second limited sliding area 13 , the push element 2 is elastically extended by the elastic element 1 and opened on the rebound bracket, and acts on the switch 43 through the touch portion 44 when extended to a certain position.

[0061] When the touch portion 44 acts on the switch 43 for a certain period of time, or when the touch portion 44 acts on the switch 43 and the pushing element 2 continues to elastically extend and open a certain distance on the rebound bracket, the driving matching portion 41 relies on the driving portion 40, or a gap is formed between the driving portion 40, and the control circuit board 19 controls the motor 30 to drive the transmission wheel 31 to rotate. When the transmission wheel 31 rotates, it drives the transmission rod 32 to rotate in one direction, and drives the driving member 33 to act on the driving matching portion 41 through the driving portion 40, and drives the pushing element 2 to automatically reset and slide in, and position and close on the rebound bracket.

[0062] The touch portion 44 is separated from the switch 43 when the pushing element 2 automatically resets and slides into the rebound bracket; when the switch 43 and the touch portion 44 are separated from each other for a certain period of time, or when the pushing element 2 is positioned and closed on the rebound bracket, the control circuit board 19 controls the motor 30 to drive the transmission wheel 31 to rotate, and the transmission wheel 31 drives the transmission rod 32 to rotate in the opposite direction when rotating, and drives the driving member 33 to reset to the initial position.

[0063] The control circuit board 19 of this embodiment controls the motor 30 in a delayed manner. That is, when the touch portion 44 acts on the switch 43 for a certain period of time, the control circuit board 19 controls the motor 30 to drive the transmission rod 32 to rotate in one direction. When the switch 43 and the touch portion 44 are separated from each other for a certain period of time, the control circuit board 19 controls the motor 30 to drive the transmission rod 32 to rotate in the opposite direction.

[0064] like Fig.10 As shown, the first limit sliding area 8, the inclined guide area 10, the heart-shaped stop area 11, and the second limit sliding area 13 are connected to each other end to end; the first conversion position 9 is located between the first limit sliding area 8 and the inclined guide area 10; the second conversion position 12 is located between the heart-shaped stop area 11 and the second limit sliding area 13.

[0065] Furthermore, a positioning portion 6 is provided on the pushing element 2 and / or the movable member 4, and an elastic member 5 is positioned by the positioning portion 6, and two ends of the elastic member 5 elastically act on the pushing element 2 and the movable member 4 respectively.

[0066] One end of the movable member 4 is rotatably or swingably arranged on the push element 2, the middle part is elastically connected to the push element 2 through an elastic member 5, and the other end is provided with a sliding part 7.

[0067] The pushing element 2 drives the movable part 4 to follow the movement when elastically telescopically sliding. When the movable part 4 moves, it drives the sliding part 7 through the elastic part 5 to always generate elastic friction force between it and the rebound bracket. The sliding part 7 always slides and / or is positioned along the trajectory of the heart-shaped slide groove 3 in a sequential direction through the elastic friction force.

[0068] The elastic member 5 is utilized to elastically act on the pushing element 2 and the movable member 4 respectively, so that the movable member 4 always elastically acts on the rebound bracket through the elastic member 5, so that when the pushing element 2 elastically expands and contracts and slides, elastic friction force is generated between the movable member 4 and the rebound bracket, which not only reduces the assembly gap among the rebound bracket, the pushing element 2, and the movable member 4, making the mutual assembly more compact and stable, but also enables the movable member 4 to perform limiting activities. That is, when the pushing element 2 is pressed, telescopically slid on the rebound support, the movable part 4 can rotate or swing with the pushing element 2, and always slide and / or position along the trajectory of the heart-shaped slide groove 3 in a sequential direction through the elastic friction force, thereby avoiding the movable part 4 from sliding along the trajectory of the heart-shaped slide groove 3 in a sequential direction due to its own rotation or swinging force, or the elastic force of the elastic element, or the pressing force, and even getting stuck and unable to move on the heart-shaped slide groove 3, thereby ensuring that the pushing element 2 can rebound to open and slide to close on the rebound support under any circumstances, regardless of whether it is assembled in a longitudinal, oblique, horizontal, or inverted manner, thereby improving the product's stability in use.

[0069] The elastic friction force generated by the movable part 4 is greater than the rotation or swing force generated by itself.

[0070] It can be known from the above description that the elastic friction force is the force exerted by the movable part 4 on the rebound support through the elastic part 5 when the push element 2 elastically expands and contracts and slides, and the rotation or swing force is the rotation or swing force generated by the end of the movable part 4 in a natural state when the rebound support is installed laterally. Since the elastic friction force is greater than the rotation or swing force, the movable part 4 will not have any displacement phenomenon when it is stationary due to the action of the elastic friction force, so as to ensure that it always slides and / or is positioned along the track of the heart-shaped slide groove 3 in a sequential direction when the push element 2 elastically expands and contracts and slides.

[0071] The rebound bracket includes a cover plate 14 and an assembly seat 15 .

[0072] The heart-shaped slide groove 3 is arranged on the cover plate 14; the cover plate 14 is fixedly covered on the assembly seat 15, and a guide portion 16 is further arranged corresponding to the heart-shaped slide groove 3, and the guide portion 16 is located at the front end of the heart-shaped slide groove 3; the sliding portion 7 is guided by the guide portion 16 to slide into the first limited sliding area 8 of the heart-shaped slide groove 3. That is, each time the sliding portion 7 slides in the direction of the heart-shaped slide groove 3, it can slide into the first limited sliding area 8 through the guiding effect of the guide portion 16.

[0073] The assembly seat 15 is provided with an assembly cavity 17, and the assembly cavity 17 is provided with a socket 18; the elastic element 1 is a compression spring and is sleeved on the socket 18, one end of which elastically acts on the assembly cavity 17 or the socket 18, and the other end elastically acts on the pushing element 2, and always generates an elastic force in the direction of the pushing element 2; the pushing element 2 is sleeved on the socket 18, and elastically retracts and contracts on the assembly cavity 17 through the elastic element 1; wherein, the elastic force generated by the elastic element 1 is greater than the elastic force generated by the elastic piece 5, so when the pushing element 2 is positioned and closed on the rebound support, the elastic element 1 will be compressed to store energy, and when the pushing element 2 is pressed, the energy can be released and elastically opened relative to the rebound support.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
