Description

Technical Field

[0001] This utility model relates to the field of battery swapping stations, specifically to a rope tensioning device, a battery hoist, and a battery swapping station. Background Technology

[0002] Currently, the rope tensioning device of the existing battery swapping stations for new energy heavy-duty trucks includes a roller assembly, an inclined tension spring, a rotating frame, and a tensioning wheel mounted on the rotating frame. Both the tension spring and the rotating frame are located within the roller assembly. The rotating frame can rotate about an axis parallel to the rotation axis of the rollers. The tension spring is connected to the rotating frame to apply a force to it. This force causes the rotating frame to rotate in one direction, thereby pressing the tensioning wheel against the rope to tension it.

[0003] However, this rope tensioning device has a complex structure and lacks a structure to protect the tension spring from excessive deformation.

[0004] Therefore, this utility model provides a rope tensioning device, a battery hoist, and a battery swapping station to at least partially solve the above-mentioned problems. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further described in detail in the detailed embodiments section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above-mentioned technical problems, this utility model provides a rope tensioning device, which includes:

[0007] support;

[0008] A connecting frame assembly is movably connected to a bracket in opposite first and second directions;

[0009] Rollers, rotatably connected to the connecting frame assembly, are used to set the ropes;

[0010] An elastic element, one end of which contacts the bracket and the other end of which contacts the connecting frame assembly, so as to apply a force parallel to the first direction to the connecting frame assembly, the force of which can cause the connecting frame assembly to move along the first direction to tension the rope.

[0011] The connecting frame assembly includes a blocking part, and the bracket and the blocking part are arranged sequentially along the first direction. When the connecting frame assembly moves along the second direction and causes the blocking part to abut against the bracket, the bracket restricts the connecting frame assembly from continuing to move along the second direction, thereby restricting the deformation of the elastic element.

[0012] According to the rope tensioning device of this utility model, the elastic element automatically moves the connecting frame assembly along the first direction when the rope is slack, thereby tensioning the rope. Furthermore, the elastic element deforms along the set direction, resulting in a simple structure for the entire rope tensioning device. The blocking part, during the movement of the connecting frame assembly along the second direction, blocks the blocking part when it reaches the support, thus limiting the position of the connecting frame assembly along the second direction. This limits the deformation of the elastic element, preventing excessive deformation and protecting the elastic element, thereby increasing its service life.

[0013] Optionally, the connecting frame assembly further includes a connecting frame and a mounting post connected to the connecting frame. The connecting frame and the support are arranged sequentially along a first direction. The mounting post is movably inserted through the support along both the first and second directions, and an elastic element is sleeved on the mounting post.

[0014] Optionally, the elastic element is located on the side of the bracket away from the connecting frame.

[0015] Optionally, the connector assembly also includes an adjuster threadedly connected to the mounting post and located between the connector and the bracket.

[0016] Optionally, the mounting column and the connecting bracket can be detachably connected.

[0017] Optionally, the connecting frame assembly further includes a blocking post connected to the connecting frame. The blocking post and the mounting post are spaced apart. The blocking post is movably inserted through the bracket in both a first direction and a second direction. A blocking part is disposed on the blocking post. In the first direction, the blocking part and the connecting frame are respectively located on both sides of the bracket.

[0018] Optionally, the blocking post and the connecting bracket can be detachably connected.

[0019] Optionally, the blocking part is detachably sleeved on the blocking post.

[0020] Optionally, the connecting frame assembly includes two mounting posts, with a blocking post located between the two mounting posts.

[0021] Optionally, the rope tensioning device further includes:

[0022] A photoelectric sensor, which is fixedly positioned relative to one of the bracket and connector assembly;

[0023] A shield, another fixed component in the bracket and connecting frame assembly, blocks the signal light emitted by the photoelectric sensor when the connecting frame assembly is in a preset position where the rope is fully slack or disconnected.

[0024] This utility model also provides a battery lifting device, which includes:

[0025] Hangers; and

[0026] The aforementioned rope tensioning device has its support fixedly mounted on the hanger.

[0027] According to the present invention, the battery lifting device includes the aforementioned rope tensioning device and an elastic element. When the rope is slack, the elastic element automatically moves the connecting frame assembly along a first direction, thereby tensioning the rope. Furthermore, the elastic element deforms along the setting direction, resulting in a simple structure for the entire rope tensioning device. The blocking part, during the movement of the connecting frame assembly along a second direction, blocks the blocking part when it reaches the support, thus limiting the position of the connecting frame assembly along the second direction. This limits the deformation of the elastic element, preventing excessive deformation and protecting the elastic element, thereby increasing its service life.

[0028] This utility model also provides a battery swapping station, which includes the aforementioned battery hoist.

[0029] According to the present invention, the battery swapping station includes the aforementioned battery hoist, which in turn includes the aforementioned rope tensioning device and an elastic element. When the rope is slack, the elastic element automatically moves the connecting frame assembly along a first direction, thereby tensioning the rope. Furthermore, the elastic element deforms along the setting direction, resulting in a simple structure for the entire rope tensioning device. The blocking part, during the movement of the connecting frame assembly along a second direction, blocks the blocking part when it reaches the support, thus limiting the position of the connecting frame assembly along the second direction. This limits the deformation of the elastic element, preventing excessive deformation and protecting the elastic element, thereby increasing its service life. Attached Figure Description

[0047] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0048] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0049] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not include any other meaning, such as a specific order.

[0050] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may also include other embodiments.

[0051] This embodiment provides a rope tensioning device. The rope tensioning device is used for a battery lifting device. The battery lifting device includes a frame (not shown), a lifting bracket 100, and a rope 101. The lifting bracket 100 is used to secure the battery pack. The lifting bracket 100 is suspended from the frame by the rope 101. By retracting or extending the rope 101, the raising and lowering of the lifting bracket 100 can be controlled. Thus, the lifting bracket 100 is controlled to move downwards to the battery pack, thereby gripping the battery pack. Then, the lifting bracket 100 is controlled to move upwards, thereby lifting the battery pack. The rope tensioning device is used to tension the rope 101 to prevent the rope 101 from slack.

[0052] Please refer to Figures 1 to 6 The rope tensioning device includes a bracket 110. The bracket 110 can be fixedly mounted to the hanger 100. For example, the bracket 110 can be welded to the hanger 100 or detachably connected to the hanger 100 by fasteners.

[0053] Alternatively, the support 110 can be a flat plate structure. Therefore, the structure of the support 110 is simple.

[0054] like Figures 3 to 6 As shown, the rope tensioning device also includes a connecting frame assembly 120 and a roller 130. The roller 130 is rotatably connected to the connecting frame assembly 120. The roller 130 is used to set the rope 101. One end of the rope 101 extends downwards, then passes over the lower edge of the roller 130 and extends upwards.

[0055] The connecting frame assembly 120 is movably connected to the support 110 along the setting direction D. The setting direction D includes a first direction D1 and a second direction D2, which are opposite. In this embodiment, the first direction D1 is vertically downward, and the second direction D2 is vertically upward. The connecting frame assembly 120 is movable relative to the support 110 along both the first direction D1 and the second direction D2. When the connecting frame assembly 120 moves relative to the support 110 along the first direction D1, it can drive the roller 130 to move along the first direction D1, thereby tensioning the rope 101.

[0056] When the connecting frame assembly 120 moves relative to the support 110 along the second direction D2, it can drive the roller 130 to move along the second direction D2, thereby slackening the rope 101.

[0057] It is understood that, in embodiments not shown, the setting direction can be any other direction at an angle to the vertical direction. For example, a horizontal direction, or a setting direction inclined to the vertical direction.

[0058] Please refer to Figures 3 to 6 The rope tensioning device also includes an elastic element 140. The elastic element 140 can be a cylindrical spring. One end of the elastic element 140 contacts the bracket 110. The other end of the elastic element 140 contacts the connecting frame assembly 120. The elastic element 140, deforming along the setting direction D, applies a force to the connecting frame assembly 120. The direction of this force is parallel to the first direction D1. This force enables the connecting frame assembly 120 to move along the first direction D1 to tension the rope 101. Thus, when the rope 101 slacks, the elastic element 140 automatically moves the connecting frame assembly 120 along the first direction D1, thereby tensioning the rope 101.

[0059] Please refer to the following: Figure 3 The connecting frame assembly 120 includes a blocking portion 126. The bracket 110 and the blocking portion 126 are sequentially arranged along a first direction D1. Thus, along the first direction D1, the blocking portion 126 is located on the side of the bracket 110 closest to the elastic member 140. That is, along the first direction D1, the blocking portion 126 and the elastic member 140 are located on the same side of the bracket 110. Thus, during the movement of the connecting frame assembly 120 along a second direction D2, when the blocking portion 126 moves to the bracket 110, the bracket 110 blocks the blocking portion 126, thereby limiting the position of the connecting frame assembly 120 along the second direction D2. This limits the deformation of the elastic member 140, preventing excessive deformation, thus protecting the elastic member 140 and increasing its service life.

[0060] In this embodiment, the elastic element 140 is configured such that when the rope 101 is slack, the elastic element 140 automatically moves the connecting frame assembly 120 along the first direction D1, thereby tensioning the rope 101. Furthermore, the elastic element 140 deforms along the setting direction D, simplifying the structure of the entire rope tensioning device. The blocking part 126 is configured such that during the movement of the connecting frame assembly 120 along the second direction D2, when the blocking part 126 moves to the bracket 110, the bracket 110 blocks the blocking part 126, thereby limiting the position of the connecting frame assembly 120 along the second direction D2. This limits the deformation of the elastic element 140, preventing excessive deformation and protecting the elastic element 140, thus increasing its service life.

[0061] Optionally, such as Figure 3As shown, the connecting frame assembly 120 also includes a connecting frame 121. The connecting frame 121 includes a bottom wall 122 and two side walls 123. The two side walls 123 are located on the same side (upper side) of the bottom wall 122. The two side walls 123 are spaced apart. Both side walls 123 are connected to the bottom wall 122. Therefore, the connecting frame 121 has high strength.

[0062] Optionally, such as Figure 4 As shown, the rope tensioning device also includes a rotating shaft 132, a bearing 131, a shaft fixing plate, and a retaining ring. The rotating shaft 132 passes through the inner ring of the bearing 131. The outer ring of the bearing 131 passes through the roller 130. Thus, the roller 130 can rotate about the axis of the rotating shaft 132 relative to the rotating shaft 132. The rotating shaft 132 passes through a side wall 123. The shaft fixing plate fits against the side wall 123 and connects to the rotating shaft 132. The retaining ring is fitted onto the rotating shaft 132 to prevent the bearing 131 from moving along the axial direction of the rotating shaft 132.

[0063] Please refer to Figures 3 to 6 The connecting frame 121 and the bracket 110 are arranged sequentially along the first direction D1. The connecting frame assembly 120 also includes a mounting post 124 and a nut 127. One end of the mounting post 124 is connected to the connecting frame 121. The mounting post 124 extends out of the connecting frame 121 along the setting direction D. The bracket 110 includes a mounting hole with its axial direction parallel to the setting direction D. The mounting post 124 is movably inserted into the mounting hole along both the first direction D1 and the second direction D2.

[0064] The elastic element 140 is sleeved on the mounting post 124. The nut 127 is threaded to the mounting post 124. Along the setting direction D, both the nut 127 and the elastic element 140 are located on the side of the bracket 110 away from the connecting frame 121. Along the setting direction D, the elastic element 140 is located between the bracket 110 and the nut 127 connected to the mounting post 124. One end of the elastic element 140 abuts against the bracket 110. The other end of the elastic element 140 abuts against the nut 127 connected to the mounting post 124.

[0065] The elastic element 140 is in a compressed state. Along the setting direction D, the blocking portion 126 is located on the side of the nut 127 connected to the mounting post 124 near the bracket 110. Along the setting direction D, the blocking portion 126 and the nut 127 connected to the mounting post 124 are spaced apart. Thus, when the rope 101 is slack, the compressed elastic element 140 applies the aforementioned force to the nut 127 it abuts against, causing the nut 127 to move downwards relative to the bracket 110, thereby tensioning the rope 101. Therefore, the structure of the connecting frame assembly 120 is simple.

[0066] It is understood that, in embodiments not shown, the elastic element is located above the support and between the support and the bottom wall. In this case, the connecting frame assembly may not include the adjusting element described later. The two ends of the elastic element are connected to the support and the bottom wall, respectively. The elastic element can be in a stretched state.

[0067] Furthermore, such as Figure 3 As shown, the connecting frame assembly 120 includes two spaced-apart mounting posts 124. Thus, the connecting frame assembly 120 passes through two mounting holes via the two mounting posts 124, resulting in smoother movement of the connecting frame assembly 120 relative to the bracket 110.

[0068] Alternatively, please continue to refer to Figure 3 The bottom wall 122 of the connecting bracket 121 has a threaded hole for mounting. The mounting post 124 is threaded into the threaded hole. In this way, the mounting post 124 and the connecting bracket 121 are detachably connected. As a result, the structure of the connecting bracket 121 and the mounting post 124 is simple and easy to manufacture.

[0069] Please refer to Figures 3 to 6 The connecting bracket assembly 120 also includes an adjusting member 128. The adjusting member 128 can be a nut. The adjusting member 128 is threaded to the mounting post 124 (the external thread on the outer circumference of the mounting post 124 is not shown). The adjusting member 128 is located between the bottom wall 122 and the bracket 110. Thus, by turning the adjusting member 128 to rotate relative to the mounting post 124, the adjusting member 128 can be moved relative to the mounting post 124 along the setting direction D, thereby adjusting the position of the adjusting member 128 relative to the mounting post 124 along the setting direction D, and consequently adjusting the range of movement of the connecting bracket assembly 120 relative to the bracket 110 along the setting direction D.

[0070] Furthermore, the adjusting member 128 can be pressed against the bottom wall 122. This increases the friction between the mounting post 124 and the bottom wall 122, thereby increasing the strength of the connection between the mounting post 124 and the bottom wall 122.

[0071] Optionally, such as Figure 3 As shown, the connecting frame assembly 120 also includes a blocking post 125. One end of the blocking post 125 is connected to the connecting frame 121. The blocking post 125 extends out of the connecting frame 121 along the setting direction D. The bracket 110 includes a blocking hole with its axial direction parallel to the setting direction D. The blocking post 125 is movably disposed through the blocking hole along a first direction D1 and a second direction D2. The blocking post 125 and the mounting post 124 are spaced apart. A blocking portion 126 is disposed on the blocking post 125. Along the setting direction D, the blocking portion 126 and the connecting frame 121 are located on opposite sides of the bracket 110. Along the radial direction of the blocking post 125, the blocking portion 126 extends to the outer side of the outer peripheral surface of the blocking post 125. Thus, the connecting frame assembly 120 has a simple structure.

[0072] In addition, the connecting frame assembly 120 is installed in the mounting hole and the blocking hole through the mounting post 124 and the blocking post 125 respectively, making the movement of the connecting frame assembly 120 relative to the bracket 110 more stable.

[0073] like Figure 3 As shown, the bottom wall 122 of the connecting frame 121 has a blocking threaded hole. The blocking post 125 is threaded to the blocking threaded hole. In this way, the blocking post 125 and the connecting frame 121 are detachably connected. As a result, the structure of the connecting frame 121 and the blocking post 125 is simple and easy to process.

[0074] Please refer to Figure 3 The blocking part 126 is a circumferentially closed annular structure. The blocking part 126 is detachably sleeved on the blocking post 125. The nut 127 is threadedly connected to the free end of the blocking post 125. Along the setting direction D, the blocking part 126 is located between the nut 127 and the bracket 110 to define the position of the blocking part 126. Thus, the blocking post 125 has a simple structure and is easy to manufacture.

[0075] like Figure 3 As shown, the blocking post 125 is located between the two mounting posts 124. Thus, the structure of the bracket 110 and the connecting frame assembly 120 is simple.

[0076] Please refer to Figure 5 and Figure 6 Optionally, the rope tensioning device further includes a photoelectric sensor 150, a baffle plate 160, a sensor mounting base, and a controller (not shown). The photoelectric sensor 150 has a transmitting tube and a receiving tube. The positions of the transmitting tube and the receiving tube are correspondingly arranged. The transmitting tube can emit signal light outward. The receiving tube can receive the signal light emitted by the transmitting tube. Optionally, the photoelectric sensor 150 can be a through-beam photoelectric switch, such as a slotted photoelectric switch.

[0077] The controller is electrically connected to the photoelectric sensor 150. The photoelectric sensor 150 is fixedly mounted on the hanger 100 via a sensor mounting base. Thus, the photoelectric sensor 150 is fixedly mounted relative to the bracket 110. A shield 160 is mounted on the connecting frame assembly 120. Thus, the shield 160 is fixedly mounted relative to the connecting frame assembly 120.

[0078] like Figure 6As shown, when the connecting frame assembly 120 is positioned at a preset position along the setting direction D, the shielding plate 160 is located at the photoelectric sensor 150. At this time, the shielding plate 160 can block the signal light emitted by the transmitting tube, preventing the receiving tube from receiving the signal light emitted by the transmitting tube. When the receiving tube does not receive the signal light emitted by the transmitting tube, the photoelectric sensor 150 sends position information to the controller. That is, the position information indicates that the connecting frame assembly 120 is at the preset position along the setting direction D. Thus, the controller can determine whether the connecting frame assembly 120 is at the preset position based on whether it receives the position information.

[0079] The preset position can be adjusted as needed. For example, when the rope 101 is completely slack or disconnected, the connecting frame assembly 120 is in the preset position. The preset position can be the position of the connecting frame assembly 120 relative to the support 110 when the adjusting member 128 in its current position contacts the support 110. At this time, the blocking part 126 moves away from the support 110.

[0080] It is understood that, in embodiments not shown, the photoelectric sensor may be disposed on the connecting frame assembly for fixed installation relative to the connecting frame assembly. The shield may be disposed on the bracket or hanger for fixed installation relative to the bracket.

[0081] This utility model also provides a battery lifting device. The battery lifting device includes the aforementioned rope tensioning device.

[0082] In this embodiment, the battery hoist includes the aforementioned rope tensioning device and the elastic element 140. When the rope 101 is slack, the elastic element 140 automatically moves the connecting frame assembly 120 along the first direction D1, thereby tensioning the rope 101. Furthermore, the elastic element 140 deforms along the setting direction D, resulting in a simple structure for the entire rope tensioning device. The blocking part 126, during the movement of the connecting frame assembly 120 along the second direction D2, when it reaches the bracket 110, blocks the blocking part 126, thus limiting the position of the connecting frame assembly 120 along the second direction D2. This limits the deformation of the elastic element 140, preventing excessive deformation and protecting the elastic element 140, thereby increasing its service life.

[0083] This utility model also provides a battery swapping station. The battery swapping station includes the aforementioned battery hoist and battery pack.

[0084] In this embodiment, the battery swapping station includes the aforementioned battery hoist, which includes the aforementioned rope tensioning device. The elastic element 140 is configured such that when the rope 101 is slack, the elastic element 140 automatically moves the connecting frame assembly 120 along the first direction D1, thereby tensioning the rope 101. Furthermore, the elastic element 140 deforms along the setting direction D, simplifying the structure of the entire rope tensioning device. The blocking part 126, during the movement of the connecting frame assembly 120 along the second direction D2, when the blocking part 126 moves to the support 110, the support 110 blocks the blocking part 126, thus limiting the position of the connecting frame assembly 120 along the second direction D2. This limits the deformation of the elastic element 140, preventing excessive deformation and protecting the elastic element 140, thereby increasing its service life.
