[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model discloses a driving structure for a hanging rail type charging pile, comprising:

[0027] An active drive component 1 is arranged on a base 2 and is used to cling to a hanging rail 3 and output power;

[0028] The driven component 4 is rotatably disposed on the top of the base 2 and hung on the hanging rail 3, and is used for bearing the weight and moving in an arc in accordance with the hanging rail 3;

[0029] The stabilizing component 5 is arranged on the top of the base 2 and is used to apply downward pressure to the side of the driven component 4 away from the rotating shaft.

[0030] The utility model provides an active driving component 1 so that the driving structure can remain in close contact with the hanging rail 3 when the thickness of the hanging rail 3 changes, and stably transmit the moving power for a long time. By providing a driven component 4, support is provided for the driving structure and the driving structure is guided to move in an arc in accordance with the hanging rail 3, thereby increasing the movement stability of the driving structure. By providing a stabilizing component 5, downward pressure is provided for the driven component 4 to avoid uneven force when the driven component 4 rotates in an arc in accordance with the hanging rail 3, thereby further improving the movement stability of the driving structure, thereby achieving the purpose of being able to output power in accordance with the track for a long time and effectively.

[0031] In one embodiment, the hanging rail 3 is an I-beam rail, and the active drive assembly 1 includes a slide rail 11 arranged on the top of the base 2, and a slide seat 12 capable of reciprocating along the length direction of the slide rail 11 is arranged on the slide rail 11, and a power wheel 13 and a top pressure assembly 14 are respectively arranged on the slide seat 12, which are located on both sides of the moving direction of the slide seat 12 and abut against the web of the hanging rail 3, and the hanging rail 3 is located between the power wheel 13 and the top pressure assembly 14;

[0032] The power wheel 13 is composed of a wheel body and a power member, wherein the power member is arranged inside the wheel body and is used to drive the wheel body to rotate.

[0033] The top pressure assembly 14 includes a support 141 arranged on the slide 12, and a movable rod 142 passing through the support 141 is arranged on the side of the support 141 close to the power wheel 13, and an adjusting nut 143 is arranged on the end of the movable rod 142 away from the power wheel 13. Abutment wheels 144 are rotatably arranged on the top and bottom of the movable rod 142, and the abutment wheel 144 is located at the end of the movable rod 142 close to the power wheel 13. A compression spring 145 for pushing the abutment wheel 144 to abut against the web of the hanging rail 3 is arranged in the support 141, and when the abutment wheel 144 and the power wheel 13 abut against the web of the hanging rail 3, the compression spring 145 is in a compressed state.

[0034] With such a design, when the power wheel 13 and the top pressure assembly 14 are both in contact with the web of the hanging rail 3, the friction between the rotation of the power wheel 13 and the web of the hanging rail 3 is utilized to push the entire driving structure forward. When the top pressure assembly 14 fails to abut against the hanging rail 3 due to the change in the curvature of the hanging rail 3, the positive push of the compression spring 145 pushes the movable rod 142 to move toward the side close to the hanging rail 3, so that the abutting wheel 144 is pushed to abut against the hanging rail 3. When the power wheel 13 fails to abut against the hanging rail 3 due to the change in the curvature of the hanging rail 3, the reverse push of the compression spring 145 pushes the support 141 to move away from the hanging rail 3, thereby driving the power wheel 13 installed on the slide seat 12 to approach and abut against the hanging rail 3, thereby achieving the effect of stable power transmission when the thickness of the track changes.

[0035] It should be noted that the power parts are mature existing technologies and will not be elaborated on here.

[0036] In one embodiment, the number of the driven components 4 is at least two, and the active driving component 1 is located between the two driven components 4;

[0037] The driven component 4 includes a bogie 41 rotatably arranged on the top of the base 2, and two roller mounting frames 42 are symmetrically arranged on the top of the bogie 41. The roller mounting frames 42 are provided with load-bearing wheels 43 that abut against the bottom wing plate of the hanging rail 3 and are located on the top of the bottom wing plate of the hanging rail 3. The minimum distance between the two load-bearing wheels 43 is less than the width of the bottom wing plate of the hanging rail 3.

[0038] With such a design, when the driving structure moves on the hanging rail 3, due to the self-weight of the driving structure, the load-bearing wheels 43 abut against the bottom wing plate of the hanging rail 3, bear the hanging gravity of the driving structure, and utilize the self-rotation of the load-bearing wheels 43 to reduce the friction resistance during movement. By arranging the load-bearing wheels 43 on the roller mounting frame 42 on the bogie 41, when the hanging rail 3 changes direction, the self-rotation of the bogie 41 is utilized to adjust the angle, so that the driven components 4 located on both sides of the driving structure's travel direction can smoothly pass through the direction change, ensuring that the charging piles can be transported stably.

[0039] It should be noted that when the driving structure moves to the bend of the hanging rail 3, since the driven components 4 have a sequence when entering the bend as a whole, when the front driven component 4 enters the bend, the rear is still on the straight section of the hanging rail 3, so the center line of the driving structure as a whole deviates from the track direction of the hanging rail 3. At this time, the power wheel 13 and the top pressure component 14 can slide and adjust on the slide rail 11 following the change in the curvature of the hanging rail 3, so that the power wheel 13 can still output power after the center line of the driving structure is offset, avoiding jamming.

[0040] In one embodiment, the driven assembly 4 further includes a driven wheel 44 rotatably mounted on the roller mounting frame 42 and abutting against the web of the hanging rail 3 .

[0041] This design increases the traveling stability of the driving structure after track wear through the bidirectional restriction of the driven wheel 44 and the load-bearing wheel 43.

[0042] In one embodiment, the stabilizing assembly 5 includes a stabilizing frame 51 symmetrically arranged on the top of the base 2, and the bogie 41 is located between the two stabilizing frames 51. The stabilizing frame 51 is rotatably provided with at least one lower pressure wheel 52 abutting against the top of the bogie 41 on one side of the roller mounting frame 42.

[0043] This design allows the lower pressure wheel 52 to abut against the bogie 41 away from the rotating shaft, thereby preventing the bogie 41 from tilting on one side due to gravity. At the same time, it can share the gravity borne by the bogie 41 and improve the smoothness of the rotation of the bogie 41.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] In addition, "plurality" means two or more.

[0047] 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 principles of the present invention should be included in the protection scope of the present invention.
