[0037] like Figures 1 to 5 As shown, this application provides a balancer. The balancer includes a housing assembly 10, a winding assembly 20, and a drive assembly 30. The housing assembly 10 includes a base 11, a housing 12, and a sealing ring 13. The housing 12 covers the base 11 and forms a cavity 14 with the base 11. The sealing ring 13 is disposed at the gap between the housing 12 and the base 11. The winding assembly 20 is disposed in the cavity 14. A pull rope 21 is wound on the winding assembly 20, and one end of the pull rope 21 extends out of the housing assembly 10. The drive assembly 30 is mounted in the cavity 14 and connected to the winding assembly 20 to release the pull rope 21 from the winding assembly 20 or to wind it onto the winding assembly 20.

[0038] In this embodiment, a sealing ring 13 is provided at the gap between the outer shell 12 and the base 11, effectively blocking rainwater from seeping into the cavity 14. The sealing ring 13 also significantly enhances the seal between the outer shell 12 and the base 11, reducing the risk of damage due to water ingress and thus lowering maintenance costs. Therefore, this balancer protects internal components from rainwater corrosion, ensures smooth contraction, improves waterproof performance, and extends service life. Simultaneously, the outer shell 12 covers the base 11 and forms the cavity 14, further protecting the winding assembly 20 and drive assembly 30 within the cavity 14 from rainwater erosion. The outer cover blocks more rainwater, further enhancing the balancer's waterproof effect and ensuring good waterproof performance.

[0039] During the use of the balancer, the drive component 30 is connected to the winding component 20 and drives the winding component 20 to rotate, so that the pull rope 21 is released from the winding component 20 or wound onto the winding component 20 to meet the user's needs.

[0040] In one embodiment, the base 11 includes a first plate 111 and a second plate 112. The first plate 111 divides the cavity 14 into a first chamber 141 and a second chamber 142, which are isolated from each other. A winding assembly 20 is installed in the first chamber 141. A drive assembly 30 is installed in the second chamber 142, and a portion of the structure of the drive assembly 30 extends from the second chamber 142 to the first chamber 141 for connecting the winding assembly 20. During the release and rewinding process, the pull cord 21 carries some rainwater into the first chamber 141. The isolation between the first chamber 141 and the second chamber 142 effectively prevents rainwater from entering the second chamber 142, protecting the drive components and other electrically charged parts in the second chamber 142 from rainwater damage and reducing the risk of short circuits and corrosion caused by rainwater.

[0041] The second plate 112 is vertically connected to the first plate 111. This arrangement increases the rigidity of the base 11, allowing the balancer to better resist deformation and damage. This arrangement also improves the stability of the balancer, ensures smooth retraction of the pull cord 21, and enhances the user experience.

[0042] In one embodiment, the housing 12 includes a first housing 121 and a second housing 122. The first housing 121 covers a first side of the first plate 111 and forms a first chamber 141 with the first plate 111. The winding assembly 20 is located within the first chamber 141. The first housing 121 protects the winding assembly 20 from damage caused by rain, dust, etc., and ensures that the pull cord 21 can be smoothly released from or wound onto the winding assembly 20. The second housing 122 covers a second side of the first plate 111 opposite to the first side and a second plate 112, and the second housing 122, the first plate 111, and the second plate 112 form a second chamber 142. The drive assembly 30 is located within the second chamber 142. The second housing 122, the first plate 111, and the second plate 112 prevent rain, dust, etc. from the external environment from entering the second chamber 142, protecting the drive assembly 30 from damage caused by rain, dust, etc. At the same time, the second housing 122, the first plate 111 and the second plate 112 are closely fitted and support each other, forming a stable connection. This enhances the overall structural strength of the balancer, allowing the housing 12 to better resist deformation and damage when subjected to external forces, and further protecting the drive assembly 30 so that it can operate more stably.

[0043] The sealing ring 13 is disposed at the gaps where the second housing 122 connects to the first plate 111 and the second housing 122 connects to the second plate 112. The sealing ring 13 tightly fills the gaps between the second housing 122 and the first plate 111, and between the second housing 122 and the second plate 112, effectively preventing water, dust, and other external impurities from entering the second chamber 142, ensuring good sealing of the second chamber 142, and improving the waterproof performance of the balancer. Therefore, the first housing 121, the second housing 122, and the sealing ring 13 form a multi-layered protection, effectively preventing rainwater from entering the cavity 14, ensuring the proper operation of the components inside the cavity 14, and improving the waterproof performance of the balancer.

[0044] Specifically, the sealing ring 13 can be made of epoxy resin. Epoxy resin has good adhesion and plasticity, and can tightly fill the gaps between the second housing 122 and the first plate 111, and between the second housing 122 and the second plate 112, forming an effective sealing barrier that can effectively prevent rainwater from seeping into the cavity 14 through the gaps. In addition, the sealing layer formed after the epoxy resin has cured has high hardness and wear resistance, can maintain a stable sealing effect for a long time, and is not prone to aging, cracking, or peeling. Epoxy resin can ensure that the balancer's sealing performance remains good for a long time, which is beneficial to extending the balancer's service life. It is understood that the sealing ring 13 can also be made of other materials, and this embodiment is not limited to them.

[0045] In one embodiment, the first plate 111 is provided with a clearance hole 1111, and the drive assembly 30 includes a reducer 31 and a motor 32. The reducer 31 is located in the second chamber 142. The reducer 31 includes an output shaft 311, which passes through the clearance hole 1111 and is fixedly connected to the winding assembly 20. The motor 32 is located in the second chamber 142 and is drivenly connected to the reducer 31. The motor 32 is drivenly connected to the reducer 31 and drives the output shaft 311 of the reducer 31 to rotate. The fixed connection between the output shaft 311 and the winding assembly 20 can drive the winding assembly 20 to rotate, causing the pull rope 21 wound on the winding assembly 20 to be released or wound onto the winding assembly 20. Therefore, by controlling the operation of the motor 32, the release or winding of the pull rope 21 onto the winding assembly 20 can be controlled.

[0046] Specifically, motor 32 can be a servo motor 32. The servo motor 32 can accurately convert voltage signals into torque and speed, enabling high-precision control and accurately controlling the length and speed of the release and rewind of the pull rope 21. The servo motor 32 also has a fast response speed, allowing for faster control of the release and rewind of the pull rope 21, ensuring the balancer can quickly respond to and execute user commands, meeting user needs. It is understood that other types of motors 32 can also be used; this embodiment is not limited to only one type.

[0047] The reducer 31 can be a planetary reducer. Planetary reducers have high transmission efficiency, reducing energy loss, improving the transmission efficiency of the balancer, and enabling precise control of the length and speed of the release and rewind of the pull rope 21. Planetary reducers are smaller in size, reducing the footprint of the drive assembly 30 and improving the integration of the balancer. It is understood that other types of reducers 31 can also be used; this embodiment is not limited to only one type.

[0048] In one embodiment, the winding assembly 20 includes a winding reel 22. A connection hole 221 is provided on the winding reel 22, and a pull rope 21 is wound around the outer periphery of the winding reel 22. An output shaft 311 passes through the connection hole 221 and is fixedly connected to the winding reel 22. A first sealing ring 222 is provided between the winding reel 22 and the reducer 31 on the side near the reducer 31, and the first sealing ring 222 surrounds the outer periphery of the connection hole 221. The output shaft 311 passes directly through the connection hole 221 on the winding reel 22 and is fixedly connected to the winding reel 22, allowing the winding reel 22 to rotate with the output shaft 311 to drive the pull rope 21 to release or rewind. This rigid connection ensures the directness and stability of the power transmission of the output shaft 311, improving the transmission efficiency of the balancer. The first sealing ring 222 can seal the connection hole 221, preventing rainwater from entering the connection hole 221 and causing the output shaft 311 to be corroded by rainwater, thereby affecting the smoothness of the rotation of the winding reel 22.

[0049] Specifically, the winding reel 22 can be configured as a ring structure, with the pull rope 21 wound around the outer ring side of the winding reel 22, and the output shaft 311 fixedly connected to the inner ring side of the winding reel 22. A flat key 223 can also be provided between the output shaft 311 and the winding reel 22. The flat key 223 strengthens the connection between the output shaft 311 and the winding reel 22, avoiding transmission failure caused by loose connection or slippage, and ensuring the continuity and reliability of the pull rope 21 operation.

[0050] In one embodiment, the winding assembly 20 further includes an end cap 224. The end cap 224 is attached to and covers the connection hole 221 on the side of the winding disc 22 opposite to the drive assembly 30. A second sealing ring 225 is provided between the end cap 224 and the winding disc 22, surrounding the outer periphery of the connection hole 221. The end cap 224 covering the connection hole 221 prevents rainwater from entering. The second sealing ring 225 seals the connection hole 221, further preventing rainwater from entering and causing corrosion of the output shaft 311, thus affecting the smoothness of the rotation of the winding disc 22. Specifically, the end cap 224 and the winding disc 22 are connected by screws, allowing the end cap 224 to be pressed against the winding disc 22 and compress the second sealing ring 225, further ensuring a more reliable seal for the second sealing ring 225.

[0051] In one embodiment, the reducer 31 includes a housing 312. The end face of the housing 312 near the first plate 111 is fitted to the first plate 111. This fit between the housing 312 and the first plate 111 allows the housing 312 to prevent rainwater from entering the second chamber 142 from the first chamber 141, creating a good barrier between the two chambers and further protecting the drive assembly 30 from rainwater erosion and damage. Furthermore, the fit between the housing 312 and the first plate 111 ensures good stability for the housing 312, thus guaranteeing the stability of the reducer 31.

[0052] In one embodiment, the balancer further includes a connecting wire 40. The connecting wire 40 passes through the second housing 122 and connects to the drive assembly 30. A waterproof connector 41 is provided at the connection point between the connecting wire 40 and the second housing 122. The waterproof connector 41 can prevent rainwater from entering the second housing 122, thereby protecting the electrical equipment inside the second housing 122 from damage and further ensuring the good waterproof performance of the balancer.

[0053] In one embodiment, the first housing 121 and the first plate 111 are connected by screws. This arrangement locks the first housing 121 onto the first plate 111, reducing the gap between the first housing 121 and the first plate 111, which helps to improve the waterproof performance of the balancer. At the same time, the screw connection facilitates quick installation and removal of the first housing 121, and also facilitates the inspection and maintenance of the winding assembly 20 after disassembly.

[0054] In one embodiment, the second housing 122 and the second plate 112 are connected by screws. This arrangement locks the second housing 122 onto the second plate 112, reducing the gap between the two and improving the balancer's waterproof performance. Simultaneously, the screw connection facilitates quick installation and removal of the second housing 122 and also allows for easy inspection and maintenance of the drive assembly 30 after disassembly.

[0055] The second chamber 142 also houses electrical equipment such as a control board 50 and a remote control module 60. The control board 50, remote control module 60, and drive assembly 30 are electrically connected. The remote control module 60 can send electrical signals to the control board 50 to control the operation of the drive assembly 30.

[0056] On the other hand, this application also provides a charging pile that includes the aforementioned balancer. Therefore, this charging pile incorporates all the technical effects of the aforementioned balancer. Since the technical effects of the balancer have already been described in detail above, they will not be repeated here.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0058] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
