Description

Technical Field

[0001] The present application generally relates to the technical field of battery replacement for new energy vehicles, and more specifically to a stacker and a battery replacement station. Background Art

[0002] The battery swap station in the related art has a stacker for storing, accessing and stacking batteries. The stacker includes a battery loading platform and a stacking frame. The battery loading platform is mounted on the stacking frame using at least one pair of linear guide assemblies so as to be able to perform lifting and lowering movements relative to the stacking frame in the vertical direction. Each pair of linear guide assemblies includes at least two slide rails. The stacking frame is provided with a slide rail mounting surface suitable for mounting the slide rails. In order to ensure that the slide rail mounting surfaces of the same pair of slide rails are in the same plane or parallel to each other, very high processing accuracy requirements are imposed on the slide rail mounting surfaces. If the processing accuracy of the slide rail mounting surface does not meet the requirements, the force between the sliding part and the slide rail will increase, thereby reducing the service life of the slide rail and the sliding part.

It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inner", "outer" and similar expressions used in this application are for illustrative purposes only and are not limiting.

[0089] Terms like "center," "parallel," "perpendicular," "aligned," "symmetrical," etc., as used in this application do not necessarily require precision but may include typical engineering tolerances.

[0090] Below, we will refer to the attached Figures 1 to 9 The specific embodiments of the stacker 150 and the battery swap station 100 having the same of the present application are described in more detail. These drawings show representative embodiments of the present application and do not limit the present application.

[0091] Reference Figures 1 to 8 The embodiment of the present application provides a stacker 150. The stacker 150 is applied to a battery swap station 100. The stacker 150 includes a loading rack 151, a stacking frame 153, a first guide assembly 154 and an adjustment connection assembly 155.

[0092] The stacking rack 153 has a first mounting surface 153a extending along a first direction. The first direction here is a vertical direction D3 or substantially a vertical direction D3. The vertical direction D3 can be referred to as a vertical direction or a height direction. In the example where the first direction is substantially a vertical direction D3, the first direction has a small angle with the vertical direction, such as any angle within a range of -5° to 5° between the first direction and the vertical direction. The first mounting surface 153a can generally be a plane, but it is not excluded that it can be made into a curved surface or other forms of surfaces.

[0093] The first guide assembly 154 is connected between the stacking frame 153 and the carrier 151. That is, the carrier 151 is installed on the stacking frame 153 through the first guide assembly 154. In this way, the carrier 151 can move relative to the stacking frame 153 along the vertical direction D3 of the stacking frame 153 through the first guide assembly 154. The first guide assembly 154 includes a first slide rail 154a and a first sliding portion 154b. The first slide rail 154a is fixed to the first mounting surface 153a, and the first slide rail 154a extends along the first direction. The first sliding portion 154b is slidably connected to the first slide rail 154a.

[0094] The adjustment connection assembly 155 is movably connected between the first sliding portion 154b and the carrier 151, so that the first sliding portion 154b can move relative to the carrier 151 in the second direction. The second direction is perpendicular or substantially perpendicular to the first mounting surface 153a. In the example where the second direction is substantially perpendicular to the first mounting surface 153a, the angle between the second direction and the first mounting surface 153a can be any angle within the range of 85° to 95°.

[0095] According to the stacker 150 of the embodiment of the present application, an adjustment connection assembly 155 is added between the carrier 151 and the first sliding portion 154b to allow the carrier 151 to move relative to the first sliding portion 154b in the second direction. By adopting the above technical solution, the problem of the installation surfaces of a pair of slide rails including the first slide rail 154a not being coplanar or parallel due to insufficient processing accuracy or assembly errors can be overcome, thereby also helping to reduce the requirements for the processing accuracy of the installation surfaces of the slide rails to reduce production costs. At the same time, the external force on the first sliding portion 154b can also be reduced, thereby increasing the life of the first guide assembly 154.

[0096] Reference Figures 1 to 3 ,as well as Figure 5 In some embodiments, the adjustment connection assembly 155 includes a first connection member 155a and a second connection member 155b. The first connection member 155a is fixedly connected to the first sliding portion 154b. The second connection member 155b is fixedly connected to the carrier 151. The first connection member 155a is movably connected to the second connection member 155b along the second direction. During the lifting and lowering movement of the carrier 151, the first connection member 155a and the second connection member 155b can adaptively move relative to each other in the second direction to adapt to the use scenario in which the mounting surfaces of a pair of slide rails including the first slide rail 154a are not coplanar or parallel.

[0097] Reference Figures 1 to 3 , Figure 5 as well as Figure 6Further, the second connecting member 155b has a guide hole 155b4 extending along the second direction. The first connecting member 155a is movably connected to the guide hole 155b4. Through the cooperation between the guide hole 155b4 and the first connecting member 155a, the movement of the first connecting member 155a relative to the second connecting member 155b can be guided to ensure that the first connecting member 155a moves along the second direction.

[0098] It is understandable that the guide hole can also be provided in the first connecting member 155a. Accordingly, the second connecting member 155b is connected to the guide hole.

[0099] See also Figure 5 and Figure 6 In some embodiments, the second connecting member 155b includes a guide block 155b1 and a bushing 155b3. The guide block 155b1 is fixedly connected to the carrier 151. The guide block 155b1 is provided with a mounting hole 155b2. The bushing 155b3 is at least partially embedded in the mounting hole 155b2. The bushing 155b3 is formed with a guide hole 155b4. In this embodiment, the bushing 155b3 is connected to the first connecting member 155a, so that the bushing 155b3 can be easily replaced separately, thereby reducing maintenance costs.

[0100] Optionally, the bushing 155b3 can be an oil-free bushing. The oil-free bushing includes a tubular portion that can be inserted into the mounting hole 155b2 and a flange mounting portion located outside the guide block 155b1. The flange mounting portion is used to be mounted to the guide block 155b1 by bolts.

[0101] exist Figure 5 and Figure 6 In the example shown, the guide block 155b1 is provided with two mounting holes 155b2 and two bushings 155b3. Accordingly, the adjustment connection assembly 155 includes two first connection members 155a.

[0102] Optionally, the first connecting member 155a includes a guide rod 155a1 and another flange mounting portion. The guide rod 155a1 is used to pass through the guide hole 155b4. The other flange mounting portion is used to be mounted to the first sliding portion 154b by bolts.

[0103] In other examples not shown, the number of mounting holes 155b2 of the guide block 155b1, the number of bushings 155b3 corresponding to the same guide block 155b1, and the number of first connecting members 155a corresponding to one guide block 155b1 may each be three or other numbers. The number of mounting holes 155b2 of the guide block 155b1, the number of bushings 155b3 corresponding to the same guide block 155b1, and the number of first connecting members 155a corresponding to one guide block 155b1 are the same.

[0104] Reference Figures 1 to 3 In some embodiments, the stacking frame 153 further has a second mounting surface 153b. The second mounting surface 153b and the first mounting surface 153a are respectively located on both sides of the carrier 151 along the width direction D2 of the stacking frame 153. And the second mounting surface 153b extends along the first direction. The stacker 150 also includes a second guide assembly 156. The second guide assembly 156 includes a second slide rail 156a and a second sliding portion 156b. The second slide rail 156a is fixed to the second mounting surface 153b. The second sliding portion 156b is slidably connected to the second slide rail 156a. The second sliding portion 156b is fixed to the carrier 151. It can be understood that the second slide rail 156a here and the above-mentioned first slide rail 154a are a pair of slide rails. Since the second sliding part 156b is fixed to the carrier 151, the adaptive position adjustment of the first sliding part 154b and the carrier 151 by the adjusting connecting component 155 is based on the second mounting surface 153b as a reference surface. Therefore, on the premise that the position of the carrier 151 relative to the second mounting surface 153b in the second direction remains unchanged or basically unchanged, the adjusting connecting component 155 can be used to adaptively adjust the position of the first sliding part 154b relative to the carrier 151 in the second direction.

[0105] It should be noted that, although the first mounting surface 153a and the second mounting surface 153b both extend along the first direction, in theory the first mounting surface 153a and the second mounting surface 153b are symmetrical, parallel or coplanar. However, in actual processing, the first mounting surface 153 and the second mounting surface 153b may be asymmetrical, non-parallel or non-coplanar due to low processing accuracy or installation errors. If the first sliding portion 154b in the first guide assembly 154 and the second sliding portion 156b in the second guide assembly 156 are both fixedly connected to the carrier 151, during the up and down movement of the carrier 151, one of the first sliding portion 154b and the second sliding portion 156b will be pulled away from the slide rail or squeezed toward the slide rail in the second direction, resulting in damage to the guide assembly or affecting the normal movement of the carrier 151. The technical solution of the present application is to solve such a problem: by setting an adjustable connecting component 155, the first sliding part 154b has space and possibility for relative movement with the loading shelf 151 in the second direction, thereby avoiding damage to the guide component, ensuring the normal movement of the loading shelf 151, and reducing the manufacturing precision requirements of the stacking rack 153 itself.

[0106] Continue to refer to Figures 1 to 3, further, the stacking frame 153 has two first mounting surfaces 153a. Along the length direction D1 of the stacking frame 153, the two first mounting surfaces 153a are respectively located at the two ends of the stacking frame 153. In other words, the two first mounting surfaces 153a are respectively located at the two ends of the stacking frame 153 along the length direction D1 of the stacking frame 153. A first guide assembly 154 and an adjustment connection assembly 155 are provided between any first mounting surface 153a and the carrier 151. The stacking frame 153 has two second mounting surfaces 153b. Along the length direction D1 of the stacking frame 153, the two second mounting surfaces 153b are respectively located at the two ends of the stacking frame 153. A second guide assembly 156 is provided between any second mounting surface 153b and the carrier 151. In this way, at both ends of the length direction D1 of the stacking frame 153, there are second mounting surfaces 153b as reference surfaces, thereby ensuring the stability of the carrier 151 during the movement of the carrier 151 along the vertical direction D3.

[0107] exist Figures 1 to 3 In the example shown, the two first mounting surfaces 153a are located at the same end of the stacking frame 153 along the width direction D2 of the stacking frame 153. The two second mounting surfaces 153b are located at the same end of the stacking frame 153 along the width direction D2 of the stacking frame 153.

[0108] Optionally, the second sliding portion 156b may be fixedly connected to the carrier 151 via an intermediate connecting member such as an angle steel.

[0109] Reference Figure 1 , Figure 2 , Figure 7 as well as Figure 8In some embodiments, the stacker 150 further includes a fall-stopping assembly 158 and a chain drive assembly 157. The fall-stopping assembly 158 includes a fall-stopping member 158a. The fall-stopping member 158a is rotatably connected to the carrier 151 between a fall-stopping position and an avoidance position around a fall-stopping axis AX parallel to the horizontal direction. The chain drive assembly 157 is used to transmit power between the power source and the carrier 151 to actuate the carrier 151 to be lifted or lowered. The chain drive assembly 157 includes a chain 157a. The chain 157a is connected to the carrier 151. The stacking frame 153 is provided with a plurality of locking holes 153c. The locking holes 153c are arranged at intervals in the vertical direction D3 of the stacking frame 153. The locking holes 153c are suitable for inserting the fall-stopping member 158a located at the fall-stopping position. The fall-stopping member 158a located at the fall-stopping position is separated from the stacking frame 153. When the chain 157a is disconnected or detached from the carrier 151 and the carrier 151 falls, the fall-stopping component 158a pivots from the avoidance position to the fall-stopping position and is inserted into one of the multiple lock holes 153c, so that the carrier 151 can be parked at a certain position along the vertical direction D3, thereby preventing the carrier 151 from falling further. By providing the fall-stopping component 158, the carrier 151 can be prevented from falling when the chain 157a is disconnected or detached from the carrier 151 and the carrier 151 falls, thereby protecting the carrier 151 and the battery pack located on the carrier 151.

[0110] See also Figure 7 and Figure 8 Further, the fall-stop assembly 158 also includes a fall-stop housing 158i and a movable connecting member 158c. The fall-stop housing 158i is directly or indirectly fixed to the cargo carrier 151. The movable connecting member 158c is movably connected to the fall-stop housing 158i along the vertical direction D3. One end of the fall-stop member 158a constitutes a locking tongue 158a1 suitable for being inserted into the lock hole 153c. The fall-stop member 158a is linked to the movable connecting member 158c. One end of the chain 157a is connected to the movable connecting member 158c to drive the fall-stop assembly 158 to rise and fall as a whole via the movable connecting member 158c, thereby driving the cargo carrier 151 to rise and fall. When the chain 157a is disconnected or detached from the movable connecting member 158c, the movable connecting member 158c descends relative to the fall-stop housing 158i. In this way, when the chain 157a is disconnected or the chain 157a is separated from the movable connecting member 158c, a force can be transmitted between the movable connecting member 158c and the falling stopping member 158a, so that the falling stopping member 158a can pivot from the avoiding position to the falling stopping position.

[0111] See also Figure 1 , Figure 2 , Figure 4 , Figure 7 as well as Figure 8Optionally, the chain drive assembly 157 also includes an upper sprocket 157b and a lower sprocket 157c, the upper sprocket 157b is located above the lower sprocket 157c, one end of the chain 157a bypasses the upper sprocket 157b and is connected to the movable connecting member 158c, and the other end of the chain 157a bypasses the lower sprocket 157c and is connected to the anti-fall housing 158i. The power source of the stacker 150 can be connected to the upper sprocket 157b through a transmission shaft to output torque to the upper sprocket 157b through the transmission shaft. In the process of the upper sprocket 157b rotating in one rotation direction, it can drive the carrier 151 to rise. In the process of the upper sprocket 157b rotating in another rotation direction, it can drive the carrier 151 to rise.
