Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0031] See also Figure 1-Figure 9 The present embodiment discloses a portable multifunctional mobile power source, including a mobile power source body 1, a storage chamber 3 is arranged below the mobile power source body 1, a plurality of strip grooves 4 are opened below the storage chamber 3, and a plurality of support blocks 5 are fixed on the storage chamber 3, a rotating frame 6 is rotatably connected to the support blocks 5, a buffer assembly is fixed at the lower end of the rotating frame 6, a moving wheel 7 is fixed at the lower end of the buffer assembly, two sets of screw rod assemblies are rotatably connected to the storage chamber 3, and a connecting piece 9 is rotatably connected between the screw rod assembly and the rotating frame 6;

[0032] A hollow column 10 is fixed on one side of the storage chamber 3, and a first rotating rod 11 is slidably connected inside the hollow column 10. One end of the first rotating rod 11 is slidably connected to the storage chamber 3, and a hand wheel 21 is fixed to one end of the first rotating rod 11. Two first bevel gears 12 are fixed on the first rotating rod 11. A second rotating rod 13 is rotatably connected inside the storage chamber 3, a winding seat 14 is fixed on the second rotating rod 13, and a traction rope 15 is installed on the winding seat 14.

[0033] The buffer assembly includes two mounting plates 61 , which are respectively fixed on the rotating frame 6 and the moving wheel 7 , a damping rod 62 is fixed between the two mounting plates 61 , a first spring 63 is sleeved on the damping rod 62 , and two ends of the first spring 63 are respectively fixed on the two mounting plates 61 .

[0034] The screw rod assembly includes a bidirectional screw rod 81, both ends of which are rotatably connected to the storage chamber 3, and two threaded blocks 82 are threadedly connected to the bidirectional screw rod 81, and the two threaded blocks 82 are rotatably connected to the two connecting plates 9. A second bevel gear 83 is fixed to the bidirectional screw rod 81, and the second bevel gear 83 is meshed with the first bevel gear 12. One end of the bidirectional screw rod 81 is sleeved with a rectangular block 85, and the rectangular block 85 is fixed to the storage chamber 3. A locking screw 84 is threadedly connected to the rectangular block 85.

[0035] A slide groove 17 is provided on the storage chamber 3, and a sealing plate 16 is slidably connected in the slide groove 17. The sealing plate 16 is elastically connected to the storage chamber 3 through a second spring 18. A resistance column 19 is fixed on the sealing plate 16, and a resistance bracket 20 is fixed on the threaded block 82. The resistance bracket 20 resists the resistance column 19.

[0036] When using the mobile power source body 1, refer to Figure 1-Figure 6, the first rotating rod 11 is driven to rotate by the hand wheel 21. At this time, the positioning pin 23 fixed on the V-shaped spring piece 22 is inserted into the first annular groove 24 in the hollow column 10, and the second bevel gear 83 is meshed with the first bevel gear 12. During the rotation of the first rotating rod 11, the two first bevel gears 12 drive the two second bevel gears 83 to rotate synchronously, prompting the two bidirectional screw rods 81 to rotate. The two threaded blocks 82 move on the bidirectional screw rods 81 at the same time, which can drive the connecting piece 9 and the resistance bracket 20 to move horizontally. The resistance bracket 20 conflicts with the resistance column 19 fixed on the sealing plate 16, prompting the sealing plate 16 to slide horizontally in the slide groove 17 to facilitate opening the strip groove 4. The second spring 18 accumulates force. During the horizontal movement of the connecting piece 9, the rotating frame 6 is driven to rotate on the support block 5, prompting the buffer assembly and the moving wheel 7 rotates in the strip groove and gradually contacts the ground, raising the height of the mobile power source body 1, so that the moving wheel 7 is in an extended state, and by pulling the traction rope 15, the second rotating rod 13 drives the winding seat 14 to rotate, and the traction rope 15 is unwound, and the mobile power source body 1 can be pulled to move on the road surface by the traction rope 15. Through the cooperation of the damping rod 62, the first spring 63 and the two mounting plates 61 in the buffer assembly, it can provide a good anti-vibration effect under complex road conditions, improve the anti-seismic buffering performance, reduce the influence of external forces on the mobile power source body 1, greatly improve the convenience of carrying the mobile power source body 1, save time and effort, and when the mobile power source body 1 is discharged after the movement is completed, the moving wheel 7 can be stored in the storage chamber 3, which can cause the bottom of the storage chamber 3 to contact with the ground, increase the contact area, and improve the stability of use. Example

[0037] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 8 A V-shaped spring piece 22 is fixed in the first rotating rod 11, and a positioning pin 23 is fixed on the V-shaped spring piece 22. The positioning pin 23 is slidably connected to the first rotating rod 11. A first annular groove 24 and a second annular groove 25 are respectively opened in the hollow column 10, and the first annular groove 24 and the second annular groove 25 are both adapted to the positioning pin 23.

[0038] A resisting rod 26 is disposed inside the first rotating rod 11 . The resisting rod 26 is elastically connected to the first rotating rod 11 via a third spring 27 . One end of the resisting rod 26 resists against the V-shaped spring sheet 22 .

[0039] A spur gear 28 is fixed on the first rotating rod 11 , and a gear ring 29 is fixed on one side of the winding seat 14 . The spur gear 28 is matched with the gear ring 29 .

[0040] In order to prevent the traction rope 15 from being damaged and contaminated by the outside world, and also to protect and preserve it, the traction rope 15 needs to be rolled up into the storage chamber 3. Figure 3-Figure 7By pressing the resistance rod 26 in the first rotating rod 11, the resistance rod 26 moves horizontally and contacts the V-shaped spring piece 22, and the third spring 27 accumulates force. The V-shaped spring piece 22 is affected by the resistance force and drives the positioning pin 23 to disengage from the first annular groove 24 and retract into the first rotating rod 11, pushing the first rotating rod 11 to move horizontally and rotate in the hollow column 10, and at the same time releasing the pressure on the resistance rod 26. When the positioning pin 23 encounters the second annular groove 25 during the movement, it can be moved by the elastic force of the V-shaped spring piece 22 itself. Under the action, the positioning pin 23 can be inserted into the second annular groove 25 to limit the first rotating rod 11, so that the spur gear 28 and the gear ring 29 can engage, and the second rotating rod 13 and the winding seat 14 can be rotated by rotating the hand wheel 21, so that the traction rope 15 can be wound onto the winding seat 14, and the locking screw 84 threadedly connected on the rectangular block 85 can limit the rotation angle of the bidirectional screw rod 81 to avoid the deviation of the position of the moving wheel 7 during the movement of the mobile power supply body 1, which affects the movement effect. Example

[0041] This embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 8 A through hole 30 is opened on the storage chamber 3, and the traction rope 15 is inserted in the through hole 30. A cleaning seat 31 is fixed on the storage chamber 3, and a fixing plate 32 is slidably connected to the cleaning seat 31. A cleaning sleeve 33 is fixed on the fixing plate 32, and the traction rope 15 is sleeved in the cleaning sleeve 33.

[0042] The fixing plate 32 is elastically connected to the storage chamber 3 via a fourth spring 34 . A resisting wedge 35 is fixed to the fixing plate 32 . A plurality of resisting blocks 36 are fixed to the winding seat 14 . The resisting blocks 36 resist against the resisting wedge 35 .

[0043] A first annular plate 37 is fixed on the second rotating rod 13, and a plurality of positioning holes 38 are opened on the first annular plate 37. A second annular plate 8 is mounted on the second rotating rod 13, and the second annular plate 8 is elastically connected to the storage chamber 3 through the fifth spring 2. A semicircular positioning block 39 is fixed on the second annular plate 8, and the semicircular positioning block 39 is adapted to the positioning hole 38.

[0044] Since the traction rope 15 will be contaminated with dust, impurities and moisture when placed on the ground after use, it is necessary to clean the traction rope 15 to keep it clean and hygienic to avoid bacterial growth. Figure 5-Figure 8The cleaning seat 31 provided on one side of the insertion hole 30 facilitates the insertion of the traction rope 15 into the cleaning sleeve 33 and the fixing plate 32 in the cleaning seat 31. The traction rope 15 can contact with the cleaning sleeve 33 during the winding process, and can clean the impurities, dust and moisture on the traction rope 15, keep it clean and sanitary, and avoid bacteria breeding, thereby ensuring the performance and safety of the traction rope 15. After cleaning, the problems on the traction rope 15 can be discovered and solved in time. During the rotation of the winding seat 14, the intermittent friction between the friction wedge 35 fixed on the fixing plate 32 can occur. At the same time, the fourth spring 34 reciprocates to store force and release elastic force, which can realize the reciprocating motion of the cleaning sleeve 33, thereby improving the effect of cleaning the surface of the traction rope 15. At the same time, when the cleaning sleeve 33 is squeezed by the fixing plate 32 and the side wall of the storage chamber 3 during the movement, the moisture can be squeezed out, so that the traction rope 15 can improve the drying effect during the cleaning process.

[0045] In order to improve the stability of the reel seat 14 after the traction rope 15 is reeled in, refer to Fig. 9 , it is necessary to limit the rotation of the second rotating rod 13, and a plurality of positioning holes 38 are opened on the first annular piece 37 fixed on the second rotating rod 13, which can be fitted with the semicircular positioning block 39 fixed to the second annular piece 8. The second annular piece 8 is elastically connected to the storage chamber 3 through the fifth spring 2, so that the semicircular positioning block 39 can always fit in the positioning hole 38, limiting the rotation of the first annular piece 37 and preventing the traction rope 15 from being in a loose state. When the rotation force of the winding seat 14 is large, the semicircular positioning block 39 can be disengaged from the positioning hole 38 when it is subjected to the resistance force of the first annular piece 37, thereby ensuring the normal operation of the winding seat 14 and avoiding affecting the winding and unwinding of the traction rope 15.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
