Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and more specifically, to a battery replacement device. Background Art

[0002] Existing battery swap stations use battery swap equipment to lift battery boxes. The battery swap equipment usually includes a main body, a telescopic arm, and a hoist. The main body is provided with a walking mechanism, which can be a roller. The walking mechanism can drive the main body to move along the length of the battery swap station. The telescopic arm is provided on the main body, and a lifting mechanism is provided on the telescopic arm. The lifting mechanism has a lifting rope.

The telescopic arm includes a plurality of movable arms, and adjacent movable arms are movably connected, and the telescopic arm can be extended into and out of the battery swap station. The lifting mechanism may be a winch, one end of the rope 5 is connected to the winch, and the other end is connected to the sling 3, and the winch winding the rope 5 can realize the lifting movement of the sling 3. The lifting mechanism may also be an oil cylinder, the movable end of the oil cylinder is connected to the rope 5, and the telescopic movement of the oil cylinder can drive the rope 5 to telescope, so that the rope 5 drives the sling 3 to lift and lower. The rope limit frame 4 is connected to the telescopic arm, and the rope limit frame 4 has a plurality of limit holes 411. A plurality of pulleys 431 are provided on the rope limit frame 4, and the limit holes 411 are located below the pulleys 431. Each of the ropes 5 passes through the corresponding pulley 431 and then turns downward and extends, and passes through the corresponding limit holes 411. The sling 3 is directly or indirectly connected to each of the ropes 5. When the battery exchange equipment of the present application is hoisting the battery box, the limit holes 411 limit the bottom of the rope 5 to prevent the bottom of the rope 5 from swinging too much, so that the sling can clamp the battery box stably and is less affected by the environment, thereby improving the convenience of the battery box hoisting operation, and achieving high battery transportation efficiency and safety, thereby avoiding the occurrence of safety accidents and damage to assets.

[0053] like Figure 1 and Figure 7As shown, the rope limiting frame 4 includes a fixing frame 43 and a limiting frame 41. The fixing frame 43 is connected to the telescopic arm, and each pulley 431 is provided on the fixing frame 43. The pulley 431 plays the role of converting the direction of the rope 5 and reducing friction resistance.

[0054] like Figure 1 and Figure 7 As shown, the fixing frame 43 is provided with a mounting shaft 432. Each pulley 431 is rotatably mounted on the mounting shaft 432, and the pulleys 431 are sequentially spaced along the length of the mounting shaft 432. The mounting shaft 432 facilitates the mounting of the pulleys 431. When the lifting mechanism is in operation, the lifting rope 5 is driven to move up and down around the pulleys 431. When the lifting rope 5 and the pulleys 431 are in rolling engagement, the pulleys 431 rotate about the mounting shaft 432 as the rotation axis.

[0055] like Figure 1 and Figure 7 As shown, the rope limiting frame 4 includes two lower extension frames 42, and the two lower extension frames 42 are respectively connected to the two sides of the fixed frame 43. The limiting frame 41 is located on the side of the lower extension frame 42 away from the fixed frame 43, and the two ends of the limiting frame 41 are respectively connected to the two lower extension frames 42. The limiting frame 41 is located below the fixed frame 43 and is spaced apart from the fixed frame 43. A plurality of limiting holes 411 are provided on the limiting frame 41. The limiting holes 411 are spaced apart in sequence along the length direction of the limiting frame 41. It should be noted that the lower extension frame 42 can be indirectly connected to the telescopic arm through the fixed frame 43.

[0056] In one possible embodiment, Figure 1 As shown, the battery exchange equipment includes: a sling adapter device 1 and a retractable anti-sway mechanism 2. The sling adapter device 1 has a matching seat 11, the matching seat 11 is connected to the lifting rope 5, and the sling 3 is connected to the sling adapter device 1. The retractable anti-sway mechanism 2 is connected to the fixed frame 43, and the retractable anti-sway mechanism 2 has a positioning component 21, and the positioning component 21 and the matching seat 11 are limited and matched to limit the shaking of the sling adapter device 1. The positioning component 21 of the retractable anti-sway mechanism 2 rises and falls synchronously with the matching seat 11. When the battery box is hoisted by the battery exchange equipment of the present application, the positioning component 21 can be limited and matched with the matching seat 11 to limit the shaking of the sling adapter device 1, so that the sling 3 can clamp the battery box stably, is less affected by the environment, and will not shake significantly even in the presence of external force, thereby improving the convenience of the battery box hoisting operation, and improving the battery transportation efficiency and safety, thereby avoiding the occurrence of safety accidents and damage to assets.

[0057] like Figure 1、 Figure 2 and Figure 4 As shown, the mating seat 11 has a through slot 111. The positioning component 21 is disposed through the through slot 111, and both ends of the positioning component 21 are respectively connected to the two scissor fork lifting frames 22.

[0058] like Figure 4 and Figure 5 As shown, the mating seat 11 is provided with an outwardly expanded groove 112 at each end. The outwardly expanded groove 112 communicates with the through-slot 111 and has an outer diameter larger than that of the through-slot 111. A bearing 115 is disposed within the outwardly expanded groove 112. The positioning member 21 is disposed through the bearing 115 and the through-slot 111. The positioning member 21 and the through-slot 111 are relatively rotatable, and the bearing 115 reduces frictional resistance between the positioning member 21 and the through-slot 111.

[0059] In one possible embodiment, Figure 7 and Figure 8 As shown, a limit switch 421 is provided on the lower extension frame 42. A trigger portion 23 is provided on the retractable anti-sway mechanism 2. When the sling 3 is raised to the limit height, the trigger portion 23 can trigger the limit switch 421. When the telescopic wall is retracted and extended, the trigger portion 23 will move up and down. When the sling 3 is raised to the limit height, the trigger portion 23 will approach and trigger the limit switch 421, indicating that the sling 3 has risen to the highest position, and the lifting mechanism will be controlled to stop working. The limit switch 421 can be a proximity switch. When the trigger portion 23 approaches the limit switch 421, the limit switch 421 can be triggered to generate a corresponding in-position signal.

[0060] The lower extension frame 42 is provided with a guide slot 422 extending longitudinally. The travel switch 421 is located on one side of the guide slot 422 along the width direction. The trigger portion 23 is disposed within the guide slot 422. The guide slot 422 is a hollow slot. When the travel switch 421 is raised or lowered along the guide slot 422, the trigger portion 23 passes through the travel switch 421 when the sling 3 is raised to its maximum height.

[0061] like Figure 1 and Figure 2As shown, the retractable anti-sway mechanism 2 includes a scissor lift frame 22, which comprises multiple connecting rod groups. Each connecting rod group includes two cross-arranged movable links 221, which are hingedly connected by a shaft. A shaft on the connecting rod group includes a trigger portion 23. The shaft can be the trigger portion 23, or the end of the shaft that extends out of the guide slot 422 can be the trigger portion 23. The trigger portion 23 can be a part of the shaft or integrally formed with the shaft. The two movable links 221 of the connecting rod group at the top of the scissor lift frame 22 are slidably connected to the fixed frame 43. The shaft of the connecting rod group at the bottom of the scissor lift frame 22 is connected to the positioning member 21. That is, the positioning member 21 is located on the rotation axis of the two movable links 221 of the connecting rod group at the bottom of the scissor lift frame 22. The two movable links 221 can be connected by a connecting shaft, which is connected to the positioning member 21. The two movable links 221 of the connecting rod group at the bottom end of the scissor fork lifting frame 22 can be crossed or staggered. During the lifting process of the sling 3, the scissor fork lifting frame 22 drives the positioning component 21 to move up and down synchronously. The scissor fork lifting frame 22 and the positioning component 21 cooperate with each other to move up and down synchronously, which can prevent or reduce the battery box hoisted by the sling 3 from shaking violently during the rising and falling process. The retractable anti-sway mechanism 2 can also be an oil cylinder, one end of the oil cylinder is fixed, and the other end (i.e., the telescopic end) is connected to the sling adapter 1. The lifting movement of the oil cylinder can cooperate with the sling adapter 1 to play an anti-sway role.

[0062] like Figure 2 、 Figure 3 and Figure 6 As shown, a positioning shaft 2211 is provided on the movable link 221 of the connecting rod group at the bottom end of the scissor fork lifting frame 22. The sling adapter device 1 has a support frame 12, the matching seat 11 is connected to the support frame 12, the sling 3 is connected to the support frame 12, and a positioning notch 121 is provided on the support frame 12. When the sling 3 is raised to the extreme position, the positioning shaft 2211 is limited to the positioning notch 121. The scissor fork lifting frame 22 limits the support frame 12 to prevent the sling adapter device 1 from shaking, thereby ensuring the accuracy and safety of the action execution of the battery exchange equipment of this application.

[0063] like Figure 3 、 Figure 4 and Figure 6As shown, the support frame 12 is provided with first connecting seats 122 on either side of the mating seat 11 along the width direction. The first connecting seats 122 have an axial hole 1221. A protruding shaft 113 is provided on either side of the mating seat 11, and the protruding shaft 113 is rotatably connected to the corresponding axial hole 1221. The protruding shaft 113 and the connecting hole are limitedly engaged, and the positioning member 21 and the protruding shaft 113 are perpendicular to each other. The cooperation between the two can limit the degree of freedom of the support frame 12. Furthermore, the mating seat 11 is provided with spring seats 114 on both sides of the protruding shaft 113 along the length direction of the mating seat 11. A spring is provided between the spring seat 114 and the support frame 12. A positioning column 123 is vertically connected to the support frame 12, and a positioning groove 1141 is provided on the spring seat 114. The end of the positioning column 123 extends to the positioning groove 1141, and the spring is sleeved on the positioning column 123. One end of the spring presses against the support frame 12, and the other end presses against the spring seat 114.

[0064] When the sling 3 is lifting the battery box, the lifting position may be uneven. For example, the front of the vehicle body on which the battery box is placed is higher than the back, causing the vehicle body surface to be not parallel to the ground, or the vehicle body on which the battery box is placed is parked on an uneven ground, causing the vehicle body surface to be unevenly tilted, etc., so that the battery box seating position has a certain tilt angle. The matching structure of the spring seat 114, the spring and the support frame 12 can enable the support frame 12 to have a certain deflection angle according to the actual environment. The spring will adaptively stretch or compress and can adapt to the tilt of the top of the vehicle on which the battery box is placed. After the sling 3 lifts the battery box on the vehicle with an uneven road surface, the battery box returns to its original position under the action of gravity. At this time, the spring recovers its deformation, making the support frame 12 flat and no longer tilted.

[0065] In one possible embodiment, Figure 2 and Figure 8 As shown, the battery exchange device includes a support wheel 24, which is rotatably mounted on the shaft having the trigger portion 23, and the support wheel 24 is located in the guide groove 422. The width of the guide groove 422 is larger than the cross-sectional diameter of the shaft, and the diameter of the support wheel 24 is consistent with the width of the guide groove 422. The support wheel 24 and the guide groove 422 can be limitedly matched, so that the support wheel 24 can move up and down along the length of the guide groove 422.

[0066] like Figure 1 and Figure 2As shown, the retractable anti-sway mechanism 2 includes two scissor-fork lifting frames 22, which are located on either side of the mating seat 11. The two ends of the positioning member 21 are connected to corresponding scissor-fork lifting frames 22. The two scissor-fork lifting frames 22 move synchronously, simultaneously driving the positioning member 21 to move upward and downward, ensuring that the positioning member 21 remains stable and stable along its length.

[0067] In one possible embodiment, Figure 1 and Figure 3 As shown, the sling adapter device 1 includes a buffer assembly 13, and the buffer assembly 13 includes a first buffer frame 131 and a second buffer frame 132. The first buffer frame 131 is connected to the support frame 12, and the first buffer frame 131 can reciprocate along a first direction relative to the support frame 12. A first elastic component (not shown) is provided between the first buffer frame 131 and the support frame 12. The second buffer frame 132 is connected to the first buffer frame 131, and the second buffer frame 132 can reciprocate along a second direction relative to the support frame 12. A second elastic component (not shown) is provided between the second buffer frame 132 and the second buffer frame 132. The sling 3 is connected to the second buffer frame 132. When the sling 3 grabs or releases the battery box, the sling 3 and the battery box to be clamped or the position where the battery box needs to be placed may not be directly aligned in the direction perpendicular to the ground, and there may be a small deviation. The sling 3 and the vehicle on which the battery box is mounted are each provided with a guide portion on one side and a guide mating portion on the other side. When the battery box hoisted by the sling 3 contacts the vehicle, the guide portion and the guide mating portion engage in a limiting manner, and the sling 3 may need to be displaced in the first direction or / and the second direction, with the angle between the first direction or the second direction being 90 degrees. During the movement of the guide portion and the guide mating portion, the second buffer frame 132 drives the sling 3 to shift and adapt. If the sling adapter 1 is configured as a rigid structure, the rigid structure is fixed and cannot be displaced, making it difficult for the sling 3 to smoothly grasp the battery box or to accurately unload the battery box at a set position. The buffer assembly 13 provides the sling 3 with space for displacement in the first and second directions. Under the cooperation of the guide portion and the guide mating portion, the sling 3 can adapt to the actual seating position according to the actual seating position, thereby resolving the problem of difficulty in grasping or unloading when the sling 3 and the battery box are not aligned vertically.

[0068] like Figure 3As shown, the support frame 12 is provided with two second connecting seats 124 on the side facing away from the mating seat 11 in the thickness direction. The first buffer frame 131 is provided with two sets of third connecting seats 1311 on the side facing away from the sling 3. Two first rotating shafts 133 respectively pass through the corresponding second connecting seats 12, and their ends are fixedly connected to the corresponding third connecting seats 1311. The first rotating shafts 133 and the second connecting seats 124 are slidably connected. The first elastic member is sleeved on each of the two first rotating shafts 133, and the ends of the first elastic member respectively abut against the second connecting seat 124 and the corresponding third connecting seat 1311. The first elastic member can be a spring.

[0069] like Figure 3 As shown, two sets of fourth connecting seats 1312 are provided on the side of the first buffer frame 131 proximal to the sling 3. Two fifth connecting seats 1321 are provided on the side of the second buffer frame 132 facing away from the sling 3. Two second rotating shafts 134 extend through the ends of the corresponding fifth connecting seats 1321 and are fixedly connected to the corresponding fourth connecting seats 1312. A second elastic component is sleeved around each of the two second rotating shafts 134, with the ends of the second elastic component abutting against the fifth connecting seats 1321 and the corresponding fourth connecting seats 1312, respectively. The second rotating shaft 134 and the fifth connecting seats 1321 are slidably connected. The second elastic component may be a spring. The buffer assembly 13 improves the fault tolerance of the battery swapping device of the present application, allowing the sling 3 to be displaced in both the first and second directions. The first direction is the length of the first rotating shaft 133, and the second direction is the length of the second rotating shaft 134. This solves the problem of difficulty in grasping or unloading when the sling 3 and the battery box are not aligned vertically.

[0070] The battery exchange equipment of the present application adopts a retractable anti-sway mechanism 2. The two scissor-fork lifting frames 22 of the retractable anti-sway mechanism 2 can perform lifting movements. The lifting mechanism can provide power to the scissor-fork lifting frames 22, which can effectively prevent the battery box from shaking during the rising and falling process. A buffer component 13 is provided on the sling adapter 1, so that the sling 3 will shift along the first direction and the second direction to adapt to the deviation between the battery box and the sling 3. When subjected to external forces (such as wind or collision with external structures), the lifting of the battery box is not affected, the work efficiency is high, and it is not easy to cause safety accidents and damage assets.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention.
