Description

Technical Field

[0001] The utility model relates to the technical field of battery swapping equipment, in particular to a self-balancing battery swapping spreader. Background Art

[0002] At present, the battery swapping spreaders on the market do not have the function of self-balancing. After the steel wire ropes of the battery swapping spreader are fatigued, the battery swapping spreader will tilt, and the tilting of the battery swapping spreader will cause the connectors of the battery box to be damaged; at the same time, it will also cause the steel wire ropes of the battery swapping spreader to be unevenly stressed and easily break. When the battery swapping spreader tilts too much, its state cannot be recognized and the risk is uncontrollable.

[0003] Chinese Patent CN105110189A discloses an automatic balancing spreader, which is composed of a lifting beam, a balance control system, a spreader driving mechanism, etc., and is suitable for the balanced lifting of large objects with unclear center of gravity positions. By receiving the information of the inclination sensor and the position sensor through the balance controller, after automatically processing the data, the balance controller issues a driving control instruction to the motor. The motor drives the spreader to move through the reducer, the lead screw and the lead screw nut, so as to adjust the position of the spreader suspension point (that is, to change the center of gravity position of the lifting), so as to achieve the balanced lifting state. The invention has a simple structure and convenient operation, avoids the trouble of manually searching for the center of gravity position multiple times, improves the lifting efficiency of large objects, and reduces the operation difficulty and lifting cost. This method requires the cooperation of two sensors to achieve self-balancing, namely the position sensor and the inclination sensor. Relatively speaking, it is more complex to implement. Summary of the Utility Model

[0004] The utility model solves the problems in the related technologies and provides a self-balancing battery swapping spreader. The deceleration motor drives the moving guide wheel to translate on the guide rail through the lead screw transmission, driving the steel wire rope to stretch the battery swapping spreader. At the same time, the balance sensor judges the tilting angle direction of the battery swapping spreader, and the left and right self-balancing mechanisms will automatically adjust the lifting height of the steel wire rope to ensure that the battery swapping spreader remains in a horizontal state. It can be achieved only with one balance sensor, which simplifies the structure and is safer and more reliable to implement.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions: A self-balancing battery swapping spreader includes two groups of self-balancing mechanisms, a balance sensor, a controller, a battery swapping spreader and a steel wire rope, which are symmetrically arranged on the left and right. The self-balancing mechanism includes a driving mechanism, a lead screw, a guide rail, a moving guide wheel, a fixed guide wheel and a bottom plate. The driving mechanism is connected to the lead screw. The lead screw is connected to the moving guide wheels on both sides through the lead screw nuts thereon. Each moving guide wheel is slidably installed on the guide rail. The balance sensor is installed on the battery swapping spreader. The controller is respectively connected to the balance sensor and the driving mechanism. One end of the steel wire rope is fixed on the fixed block above the fixed guide wheel and sequentially passes around the moving guide wheel and the fixed guide wheel and extends downward to the other end and is connected to the battery swapping spreader.

[0006] As a preferred solution, it further includes a guiding mechanism, which includes a guiding shaft and a guiding sleeve corresponding in position. The guiding sleeve is installed on the bottom plate, and the guiding shaft is installed on the battery swapping spreader.

[0007] As a preferred solution, the driving mechanism and the guide rail are both installed on the bottom plate, and the bottom plate is provided with a hole for the steel wire rope to pass through.

[0008] As a preferred solution, the two moving guide wheels of each self - balancing mechanism are installed on the sliding plate, and the sliding plate is fixedly connected to the two screw nuts.

[0009] As a preferred solution, the driving mechanism is a reduction motor.

[0010] As a preferred solution, both the moving guide wheel and the fixed guide wheel are installed on the guide wheel seat.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The reduction motor of the present utility model drives the moving guide wheel to translate on the guide rail through the screw drive to drive the steel wire rope to stretch the battery swapping spreader. At the same time, the balance sensor judges the tilting angle direction of the battery swapping spreader, and the left and right self - balancing mechanisms will automatically adjust the lifting height of the steel wire rope to ensure that the battery swapping spreader remains in a horizontal state. This can be achieved with only one balance sensor, which simplifies the structure and is safer and more reliable to implement; it increases the service life of accessories such as the steel wire rope and the guiding shaft; it runs stably and reduces the failure rate; it protects accessories such as the battery box and the connector; and it has a modular design, which is convenient and reliable for maintenance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0019] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the sizes of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0021] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure for the device. For example, if the device in the drawing is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0022] In addition, it should be noted that the use of terms such as "first", "second", etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, a self - balancing power - swapping sling includes two sets of self - balancing mechanisms 1 symmetrically arranged left and right, a balance sensor 2, a controller, a power - swapping sling 3, and a steel wire rope 4. The self - balancing mechanism 1 includes a driving mechanism 11, a lead screw 12, a guide rail 13, a moving guide wheel 14, a fixed guide wheel 15, and a bottom plate 18. The driving mechanism 11 is connected to the lead screw 12. The lead screw 12 is connected to the moving guide wheels 14 on both sides through a lead screw nut 16 thereon. Each moving guide wheel 14 is slidably installed on the guide rail 13. The balance sensor 2 is installed on the power - swapping sling 3. The controller is respectively connected to the balance sensor 2 and the driving mechanism 11. One end of the steel wire rope 4 is fixed to an L - shaped fixing block 17 above the fixed guide wheel 15. The L - shaped fixing block 17 includes a vertical plate and a horizontal plate. One end of the vertical plate is fixed to the bottom plate 18, and the other end is connected to the horizontal plate. The horizontal plate is located above the fixed guide wheel 15. The steel wire rope 4 sequentially passes around the moving guide wheel 14, the fixed guide wheel 15 and extends downward to the other end and is connected to the power - swapping sling 3.

[0024] In one embodiment, a guiding mechanism 5 is further included. The guiding mechanism 5 includes a guiding shaft 51 and a guide sleeve 52 corresponding in position. The guide sleeve 52 is installed on the bottom plate 18, and the guiding shaft 51 is installed on the power - swapping sling 3. There are also two sets of the guiding mechanism 5, which can be symmetrically distributed or distributed along the diagonal. When the power - swapping sling 3 moves up and down, the guiding shaft 51 can move up and down in the guide sleeve 52 to play a guiding role.

[0025] In one embodiment, the driving mechanism 11 and the guide rail 13 are both mounted on the bottom plate 18. The bottom plate 18 is provided with holes through which the wire ropes 4 pass. Since there are four wire ropes 4, there are also 4 holes on the bottom plate 18.

[0026] In one embodiment, the two moving guide wheels 14 in each set of self-balancing mechanisms 1 are mounted on the sliding plate 19 through guide wheel seats, and the sliding plate 19 is fixedly connected to the two screw nuts 16.

[0027] In one embodiment, the driving mechanism 1 is a reduction motor.

[0028] In one embodiment, the fixed guide wheel 15 is mounted on the bottom plate 18 through a guide wheel seat.

[0029] The working principle is as follows:

[0030] During operation, when the battery changing spreader 3 transports the battery box 6, the wire ropes 4 are stretched and lifted. At the same time, the balance sensor 2 judges the tilting angle direction of the battery changing spreader 3. If the right side is higher, then through the controller, the reduction motor of the left self-balancing mechanism 1 drives the moving guide wheel 14 to translate on the guide rail 15 through the screw drive to drive the wire rope 4 to automatically adjust the lifting height, ensuring that the battery changing spreader 3 remains in a horizontal state; if the left side is higher, then through the controller, the reduction motor of the right self-balancing mechanism 1 drives the moving guide wheel 14 to translate on the guide rail 15 through the screw drive to drive the wire rope 4 to automatically adjust the lifting height, ensuring that the battery changing spreader 3 remains in a horizontal state.

[0031] The above is the preferred embodiment of the present invention. Those skilled in the art of the present invention can also make changes and modifications to the above embodiment. Therefore, the present invention is not limited to the above specific embodiment, and any obvious improvement, replacement or variation made by those skilled in the art on the basis of the present invention belongs to the protection scope of the present invention.
