Description

Technical Field

[0001] This utility model relates generally to the technical field of battery swapping, and more specifically to a battery swapping station hoisting assembly and a battery swapping station. Background Technology

[0002] Existing top-mounted battery swapping stations for new energy heavy-duty trucks use wire rope winches to lift batteries. During battery swapping operations, if the winch drum drive motor brake malfunctions, the loss of braking function can cause the battery and lifting device to fall. This could result in minor damage to the vehicle, or even a fire or explosion risk from the rapid fall and impact of the battery. Furthermore, a winch drum brake malfunction (or inaccurate placement of the lifting device causing the positioning sensor to fail to engage or malfunction, resulting in the lifting device being on the battery while the winch drum motor continues to rotate without a stop command) can lead to the continuous release of the wire rope. This could cause the wire rope to lose tension and detach from the winch drum's grooves. Improper handling afterward can damage the wire rope and cause a safety accident.

[0003] Therefore, there is a need to provide a battery swapping station hoisting assembly and a battery swapping station to at least partially solve the above problems. Utility Model Content

[0093] 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.

[0094] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the invention.

[0095] The ordinal numbers such as "first" and "second" used in this utility model are merely identifiers and do not have any other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0096] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0097] This utility model provides a battery swapping station hoisting component and a battery swapping station using the hoisting component.

[0098] Please see Figure 1 The battery swapping station 100 includes a battery (not shown) and a battery swapping station lifting assembly 200. Specifically, the battery swapping station lifting assembly 200 includes a winch mechanism 210 and a lifting device 220. The lifting device 220 is used to lift the battery. The lifting device 220 is connected to the lower part of the winch mechanism 210 by a rope 201. The winch mechanism 210 is used to drive the lifting device 220 up and down in the vertical direction DH by winding and releasing the rope 201. The battery swapping station lifting assembly 220 also includes a traversing mechanism (not shown) for driving the winch mechanism 210 to move along a second horizontal direction D2. For example, the winch mechanism 210 has a main frame 218 adapted for the traversing mechanism to improve the flexibility of the battery swapping station lifting assembly 200 and facilitate its use.

[0099] Please see now Figures 1 to 4 The hoisting mechanism 210 includes a base frame 211, a hoisting drum 212, a rotating shaft 213, and a brake 240. The rotating shaft 213 extends in a horizontal direction. Figure 2In this configuration, the rotating shaft 213 extends along a first horizontal direction D1, which intersects with the aforementioned second horizontal direction D2. Preferably, the first horizontal direction D1 is perpendicular to the second horizontal direction D2. Specifically, the winch drum 212 is sleeved and connected to the radially outer side of the rotating shaft 213, allowing the winch drum 212 to rotate about the rotating shaft 213 as an axis. The rope 201 is wound around the radially outer peripheral wall of the winch drum 212. The rotating shaft 213 includes a braking section 216 extending outward from the outer side of the winch drum 212 along a horizontal direction (e.g., the first horizontal direction D1). That is, the winch drum 212 can rotate relative to the base frame 211 with its own axis as an axis. The winch drum 212 is connected to the base frame 211, and the braking section 216 is located on the outer side of the base frame 211. A brake 240 is arranged radially outward from the braking section 216. The brake 240 is used to clamp the shaft 213 when the winch drum 212 stalls, so as to stop the winch drum 212 from rotating.

[0100] According to the plan, a brake 240 is added to the hoisting assembly 200 of the battery swapping station at the winch drum 212. The brake 240 can be quickly activated to brake the winch drum 212 in the event of a stall, so as to ensure the safe conduct of the hoisting operation.

[0101] Please continue reading. Figures 1 to 4 Furthermore, the hoisting mechanism 210 also includes a wheel 214. The wheel 214 is coaxially connected to the shaft 213 and located radially outside the braking section 216. That is, the radial dimension of the wheel 214 is larger than the radial dimension of the braking section 216, which shortens the clamping stroke of the brake 240 compared to directly clamping the braking section 216, facilitating rapid clamping by the brake 240 and enabling the hoisting drum 212 to stop in time. Specifically, the brake 240 is connected to the base frame 211 and is arranged radially outside the wheel 214 to clamp the wheel 214 when the hoisting drum 212 stalls. The brake 240 includes brake shoes 241, which are arranged in pairs and are arranged radially outside the wheel 214. It should be noted that the two brake shoes 241 in the pair are movable between the clamping position and the release position along the radial direction of the shaft 213. The two brake shoes 241 in the clamping position move to abut against the wheel disc 214, so that the winch drum 212 stops rotating; the two brake shoes 241 in the release position move away from the wheel disc 214. Preferably, the brake 240 is constructed as an electromagnetic drum brake.

[0102] Please see now Figure 1 , Figure 3 and Figure 4The battery swapping station hoisting assembly 200 also includes a speed measuring component 215 and a control device 217. Specifically, the speed measuring component 215 is connected to the base frame 211. The speed measuring component 215 is located on the side of the winch drum 212 away from the brake section 216 along its own axial direction. The speed measuring component 215 is electrically connected to the winch drum 212. The speed measuring component 215 is used to measure the rotational speed of the winch drum 212. The control device 217 is electrically connected to the speed measuring component 215 and the brake 240 to send a clamping signal to the brake 240 when the rotational speed measured by the speed measuring component 215 exceeds a predetermined value. It can be understood that the aforementioned "stall" and the "rotational speed exceeding a predetermined value" here have the same meaning, both referring to the actual rotational speed of the winch drum 212 being greater than the set maximum rotational speed. When the speed measuring component 215 measures that the actual rotational speed of the winch drum 212 is greater than the set maximum rotational speed, it is determined that the winch drum 212 has stalled. The speed measuring component 215 sends a stall signal to the control device 217, which then sends a clamping command (signal) to the brake 240, so that the brake 240 locks the wheel disc 214, thereby achieving the purpose of braking the winch drum 212.

[0103] Please see now Figure 1 and Figure 5 The battery swapping station hoisting assembly 200 also includes a rope anti-slack device 230, which is mounted on the lifting device 220. The end of the rope 201 furthest from the winch mechanism 210 is connected to the rope anti-slack device 230. The rope anti-slack device 230 includes a mounting base 231, a pulley 232, and a tensioning mechanism 250. The mounting base 231 is fixed to the top wall of the lifting device 220. For example, the mounting base 231 is connected to the top wall of the lifting device 220 by multiple bolts. For details, please refer to... Figures 5 to 7 Pulley 232 is rotatably connected to mounting base 231 about its own pulley axis. The axis of pulley 232 extends in a horizontal direction (e.g., a first horizontal direction D1). Rope 201 passes through the groove 233 of pulley 232 and around the bottom of pulley 232, so that in the horizontal plane, rope 201 is divided into a first rope segment 202 and a second rope segment 203 located on both sides of pulley 232 in the radial direction. Tensioning mechanism 250 extends in the radial direction of pulley 232. The first end 252 of tensioning mechanism 250 is rotatably connected to mounting base 231 about the axis of pulley 232, and the second end 253 of tensioning mechanism 250 abuts against the first rope segment 202 and is located on the side of the first rope segment 202 opposite to pulley 232. It should be noted that the tensioning mechanism 250 is used to rotate in a second rotation direction when the rope 201 applies a force to the second end 253 of the tensioning mechanism 250 to cause the tensioning mechanism 250 to rotate in a first rotation direction. The first rotation direction is towards the bottom of the pulley 232, and the second rotation direction is opposite to the first rotation direction.

[0104] Please continue reading. Figures 5 to 7The rope anti-loosening device 230 also includes an elastic member 234. One end of the elastic member 234 is connected to the mounting base 231, and the other end of the elastic member 234 is connected between the first end 252 and the second end 253 of the tensioning mechanism 250. When the tensioning mechanism 250 rotates in a first rotation direction, the elastic member 234 is elastically stretched. Preferably, the elastic member 234 is constructed as a nitrogen spring. Nitrogen springs have technical advantages such as high force density, long life, and strong environmental adaptability. Specifically, the tensioning mechanism 250 includes two symmetrically arranged tensioning arms 251, which are respectively arranged on both sides of the pulley 232 in the axial direction. The tensioning arms 251 extend in the radial direction of the pulley 232. The first end 252 of the tensioning arm 251 corresponds to the first end 252 of the tensioning mechanism 250, and the second end 253 of the tensioning arm 251 corresponds to the second end 253 of the tensioning mechanism 250. The rope 201 acts simultaneously on the second ends 253 of both tensioning arms 251. Accordingly, one end of the elastic member 234 is connected to the mounting base 231, and the other end of the elastic member 234 is connected between the first end 252 and the second end 253 of the tensioning arm 251. When the tensioning arm 251 rotates in the first rotation direction, the elastic member 234 is elastically stretched. Preferably, there are two elastic members 234, which are respectively arranged on both sides of the pulley 232 in the axial direction. The tensioning arm 251 extends in the radial direction of the pulley 232, which reduces the stroke of the elastic member 234, preventing the elastic member 234 from being in a large-stroke stretched state for a long time and losing its elasticity, thus ensuring the effective maintenance of the tensioning function.

[0105] Figure 5 In this tensioning mechanism 250, a third groove 255 is provided at the second end 253. The opening of the third groove 255 faces the pulley 232, and the rope 201 passes through and contacts the third groove 255, so that the second end 253 of the tensioning mechanism 250 interacts with the rope 201. Specifically, the tensioning mechanism 250 includes a third roller 254, which is provided at the second end 253. The third roller 254 is disposed between two tensioning arms 251 and is pivotally connected to the two tensioning arms 251 about its own axis. The third groove 255 is an annular groove extending in the circumferential direction on the third roller 254. Furthermore, the rope anti-loosening device 230 also includes a limiting mechanism 235. The limiting mechanism 235 is connected to the mounting base 231, and the limiting mechanism 235 is located on the side of the second rope 203 away from the pulley 232, so as to form a limiting space between the limiting mechanism 235 and the pulley 232 to limit the second rope 203. For example Figure 5 and Figure 6In this configuration, the limiting mechanism 235 is constructed as a second roller, which is connected to the mounting base 231 via a connecting shaft 237. The second roller is rotatably connected to the mounting base 231 about the connecting shaft 237. The second roller is provided with a second groove 236 suitable for the rope 201, which is an annular groove extending in the circumferential direction on the second roller. The second groove 236 and the third groove 255 are located on opposite sides of a vertical plane passing through the axis of the pulley 232. The rope 201 passes through the second groove 236. The second groove 236, the third groove 255, and the groove 233 of the pulley 232 are aligned along the extending direction of the axis of the pulley 232.

[0106] Please continue reading. Figures 5 to 7 The rope anti-loosening device 230 also includes a detection component 260, and a control device 217 is electrically connected to the detection component 260 and the hoisting mechanism 210. The detection component 260 is at least connected to the tensioning mechanism 250 and is used to send a positioning signal to the control device 217 when the tensioning mechanism 250 rotates to its limit position in the second rotation direction. The control device 217 is used to control the hoisting mechanism 210 to stop operating after receiving the positioning signal. Specifically, the detection component 260 includes a sensor 261, a detection arm 262, and a positioning member 265. The detection arm 262 is connected to the tensioning mechanism 250 and rotates synchronously with the tensioning mechanism 250. The positioning member 265 is disposed on the mounting base 231, and when the tensioning mechanism 250 rotates to its limit position in the second rotation direction, the detection arm 262 abuts against the positioning member 265 or the distance between the detection arm 262 and the positioning member 265 is less than a preset value. Sensor 261 is disposed on detection arm 262 or positioning member 265. When detection arm 262 abuts against positioning member 265 or the distance between detection arm 262 and positioning member 265 is less than a preset value, sensor 261 sends a positioning signal to control device 217. Preferably, detection arm 262 includes a connecting part 263 and an action part 264 connected to each other, and the end of connecting part 263 away from action part 264 is connected to the first end 252 of tension arm 251. Sensor 261 is connected to mounting base 231 via positioning member 265.

[0107] The following describes the coordinated operation of the tensioning mechanism 250 and the control device 217.

[0108] The hoisting mechanism 210 controls the lifting device 220 to rise and fall vertically DH via the rope 201. (See also...) Figure 5 and Figure 6 The detection component 260 is in an untriggered state. When the rope 201 slackens, the elastic member 234 pulls the tensioning arm 251 to pivot about an axis extending along the first horizontal direction D1, specifically, to pivot counterclockwise, so that the third roller 254 acts on the first section of the rope 202, thereby ensuring that the rope 201 remains taut. When the detection arm 262 pivots counterclockwise with the tensioning arm 251 to... Figure 7When the indicated position is reached, the detection component 260 is in a triggered state. The sensor 261 sends a positioning signal to the control device 217. Upon receiving the positioning signal, the control device 217 controls the hoisting mechanism 210 to stop operating to ensure the safe conduct of the hoisting operation.

[0109] According to the battery swapping station hoisting assembly of this utility model, a brake is added to the winch drum. This brake can quickly activate and brake the winch drum in the event of stall. Furthermore, a rope anti-slackening device ensures that the hoisting ropes are always taut, preventing them from detaching from the winch drum. When the detection component is triggered, the control device will promptly stop the winch drum from rotating, eliminating safety hazards caused by the rope anti-slackening device failing to maintain rope tension.
