It has the vital effect of balancing the supply and demand of electricity. Specifically, it can effectively store electric energy when there is surplus electric energy, and can supply electric energy in a timely and accurate manner when there is a shortage of electric energy. Not only that, it can also play the key role of backup power supply. Especially in specific scenarios such as outdoor camping, people generally choose to carry energy storage backup power devices and use them as backup power supply.

[0003] However, in actual situations, when people are at camping sites that are completely inaccessible to vehicles, users will inevitably need to lift the energy storage backup device with pure manpower to move it to the corresponding camping site.

The worm 71 is rotatably provided in the regulating cavity 17, and the upper end of the worm 71 passes through the regulating cavity 17 and is fixedly connected with a knob 18. The worm 71 and the worm wheel 72 are meshed, and the unfolded helix angle of the worm 71 is smaller than the friction angle between the worm 71 and the worm wheel 72. Through the transmission cooperation of the worm 71 and the worm wheel 72, it is convenient for the user to control the rotation of the pull rod 6 through the knob 18 to adjust the required pulling angle, and the unfolded helix angle design of the worm 71 can realize the self-locking between the worm 71 and the worm wheel 72, avoiding the tediousness of manual locking;

[0028] The lower side of the support seat 2 is slidably connected with a support plate 8, and a plurality of buffer shock absorbing mechanisms 9 are fixedly arranged on the lower side of the support plate 8. The buffer shock absorbing mechanisms 9 include a mother seat 91, a piston block 92 and a child seat 93. The mother seat 91 is fixedly arranged on the lower side of the support plate 8, and the child seat 93 is slidably connected with the mother seat 91 through the piston block 92. A linear bearing that slides with the child seat 93 is arranged on the mother seat 91 to ensure the sealing of the sliding of the child seat 93 and the mother seat 91. The walking wheel 10 is rotatably arranged at the lower end of the child seat 93, and the piston block 92 is fixedly connected to the female seat 91 through a buffer spring 19, and the lower space of the piston block 92 is injected with a coolant 15, and the lower space of the piston block 92 is connected to the heat dissipation cavity 12 through a corrugated telescopic tube 14.

The limit rod 28 is fixedly connected, and the limit rod 28 is slidably connected to the support plate 8. The thread lead angle of the lead screw 111 is less than the equivalent friction angle. Through the transmission cooperation of the bevel gear assembly 112, it is convenient for the user to control the rotation of the lead screw 111 through the turning handle 27, and then cooperate with the support plate 8 to control the lifting of each walking wheel 10. The setting of the limit rod 28 can limit the support plate 8 to prevent the support plate 8 from rotating with the lead screw 111. The design of the thread lead angle of the lead screw 111 can achieve self-locking between the lead screw 111 and the support plate 8 to avoid the tediousness of manual locking.

[0030] A heat dissipation cavity 12 is provided on the support seat 2, and a plurality of heat dissipation blocks 13 are fixedly arranged on the heat dissipation cavity 12. The heat dissipation cavity 12 and the corresponding buffer shock absorbing mechanism 9 are connected through a corrugated telescopic tube 14. Coolant 15 is injected into the heat dissipation cavity 12 and the buffer shock absorbing mechanism 9. A plurality of vibration blocks 20 are rotatably arranged in the heat dissipation cavity 12, and a waterproof ceramic piezoelectric sheet 21 is embedded in the vibration block 20. The waterproof ceramic piezoelectric sheet 21 is electrically connected to the energy storage backup box 3. Through the waterproof ceramic piezoelectric sheet 21, the vibration of the coolant 15 can be used to generate electrical energy to supplement the device to a certain extent, so as to achieve a certain energy-saving purpose.

[0031] The base 1 is provided with a cleaning mechanism 16 matched with the running wheel 10, and the cleaning mechanism 16 is composed of a support frame 161, a micro motor 162 and a brush roller 163. The support frame 161 is fixedly arranged on the base 1, and the micro motor 162 is fixedly arranged on the support frame 161. The output end of the micro motor 162 is fixedly connected to the brush roller 163, and the bristles on the brush roller 163 correspond to the corresponding running wheel 10. Through the provided micro motor 162, the brush roller 163 can be controlled to rotate to automatically scrape and clean the running wheel 10, so as to avoid the tediousness of manual cleaning;

[0032] A collecting groove 25 corresponding to the brush roller 163 is provided on the base 1, and a positioning slot 26 matching the support seat 2 is provided on the base 1. Through the set collection groove 25, the dirt generated during the cleaning process of the brush roller 163 can be located and collected. The setting of the positioning slot 26 facilitates the positioning and docking of the support seat 2 and the base 1.

[0033] The operating principle of the present invention is now described as follows:

[0034] When it is necessary to carry the energy storage backup device to the camping site, the support seat 2 is separated from the base 1, and the base 1 is placed on the car, waiting for subsequent use. Then, the turning handle 27 is turned, and the turning handle 27 controls the rotation of the lead screw 111 through the bevel gear assembly 112. During the rotation of the lead screw 111, each walking wheel 10 is driven to move out of the support seat 2 through the support plate 8. After the walking wheel 10 contacts the ground, the knob 18 is turned, and the knob 18 controls the rotation of the worm 71. Under the transmission cooperation of the worm gear 72, the rotating shaft 5 drives the pull rod 6 to rotate. After the pull rod 6 rotates to the required angle, the knob 18 is stopped. At this time, the user can use the pull rod 6 to cooperate with each walking wheel 10 to drag the device to move, thereby avoiding the labor loss of manual handling and greatly improving the portability of the device.

[0035] When the device is moving on the walking wheel 10, if there are potholes and uneven roads, the buffer shock absorbing mechanism 9 will intervene and cooperate with the walking wheel 10 to achieve the purpose of buffering and shock absorbing. Specifically, when the walking wheel 10 encounters a pothole and uneven road, the walking wheel 10 will cooperate with the sub-seat 93 and the piston block 92 to squeeze the buffer spring 19 to consume the collision force, and when the buffer spring 19 rebounds, the piston block 92 will press down the coolant 15 on the lower side, and the viscous resistance of the coolant 15 can be used to consume the rebound energy of the buffer spring 19, thereby ensuring the buffering and shock absorbing effect during the movement of the entire device;

[0036] In addition, the piston block 92 will continuously squeeze the coolant 15 during the continuous movement, causing the coolant 15 in the heat dissipation cavity 12 to fluctuate, thereby causing the vibration block 20 in the heat dissipation cavity 12 to vibrate. The vibration force can be used to make the waterproof ceramic piezoelectric sheet 21 generate electrical energy, which is added to the energy storage backup box 3, thereby adding a part of the electrical energy to the energy storage backup box 3, and playing a certain energy-saving role.

[0037] After the device is moved to the target point, the handle 27 is turned in the opposite direction. Similarly, each walking wheel 10 will be retracted to ensure the flatness of the bottom surface of the support seat 2, thereby ensuring the stability of the placement of the entire device. Then, each electric push rod 23 is controlled to insert the insertion rod 24 into the ground to ensure the stability of the placement of the entire device. Then, the electrical appliances that need to be powered are connected to the interface of the energy storage backup box 3 for use. The heat energy generated by the energy storage backup box 3 during operation will be conducted to the heat dissipation cavity 12, absorbed by the coolant 15 in the heat dissipation cavity 12, and conducted to the outside in conjunction with each heat dissipation block 13 to ensure the heat dissipation of the energy storage backup box 3.

[0038] When camping is over and the device is moved to a parking spot, the support seat 2 is docked with the base 1 in cooperation with the positioning slot 26, and then each micro motor 162 is started. The micro motor 162 controls the rotation of the brush roller 163. During the rotation of the brush roller 163, the bristles thereon can scrape and clean the travel wheel 10. During the cleaning process, under the action of friction, the travel wheel 10 will rotate synchronously, and cooperate with the scraping and cleaning of the brush roller 163. The mud generated during the cleaning will fall into the collection trough 25 for centralized collection, so as to avoid being directly swept to the outside and polluting the external environment. In the later stage, the mud generated during the cleaning process can be collected and transferred to the corresponding garbage disposal point for treatment through the base 1.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
