Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery swap equipment, and particularly relates to an opening and closing device, a vehicle carrying platform and a battery swap station. BACKGROUND

[0002] Nowadays, electric vehicles are increasingly popular among consumers. After the electric energy of an electric vehicle is used up, the electric vehicle needs to be charged. Due to the limitation of current battery technology and charging technology, it takes a long time to fully charge an electric vehicle, which is not as simple and fast as refueling a vehicle. Therefore, in order to reduce the waiting time of users, replacing the battery when the electric energy of an electric vehicle is almost exhausted is an effective means. In order to facilitate battery replacement and meet the battery replacement needs of an increasing number of electric vehicles, a battery swap station needs to be built.

[0003] When performing a battery swap operation, a battery swap vehicle needs to be driven into a battery swap position of a battery swap station first. The battery swap station is provided with a battery swap opening below the battery swap position. A battery swap device below the battery swap opening takes down a battery pack with low electric energy and then packs a battery pack with full electric energy onto the vehicle to complete a battery swap operation. However, this battery swap operation has the following problems: first, the battery swap vehicle needs to pass through the battery swap opening when driving to the battery swap position. The battery swap device below the battery swap opening and the like are exposed below the driver's field of view. The driver needs to exert additional attention to avoid the battery swap opening in the already compact battery swap station, which causes great psychological pressure to the driver and greatly affects the user's battery swap experience; second, in the process of passing through, sundries and the like attached to the chassis of the battery swap vehicle may fall onto the battery swap device below through the battery swap opening. In addition, the battery swap opening is opened for a long time. Dust and sundries inside the battery swap station may also pass through the battery swap opening to adversely affect the battery swap device below, increasing the cleaning and maintenance pressure on the battery swap device. CONTENT OF THE UTILITY MODEL

[0004] The application provides an opening and closing device, a vehicle carrying platform and a battery swap station to solve the technical problems that the user's battery swap experience is poor due to great driving pressure in the conventional battery swap station, and the battery swap device is easily affected by dust and sundries.

[0005] The technical scheme adopted by the application is as follows:

[0006] An opening and closing device is installed above a battery swap opening of a battery swap station to open or close the battery swap opening. The opening and closing device comprises a driving mechanism and a shielding piece. The driving mechanism drives the shielding piece to move in a horizontal direction to close or open the battery swap opening.

[0007] The opening and closing device of the present application can open or close the battery replacement opening. When the battery replacement vehicle is performing the battery replacement operation, the vehicle needs to pass through the battery replacement opening to reach the preset battery replacement position. During the displacement of the vehicle, the shielding piece closes the battery replacement opening, so that the battery replacement equipment below the battery replacement opening is avoided from being exposed to the driver's field of view, the driver does not need to exert additional attention to avoid the battery replacement opening, which greatly reduces the psychological pressure of the user and helps to increase the user's battery replacement experience. In addition, when the shielding piece closes the battery replacement opening, it can serve as a bearing platform for the battery replacement vehicle to drive through, preventing the battery replacement vehicle from falling off the battery replacement opening due to vehicle deviation, further improving the user's battery replacement experience. During the passage of the vehicle, the shielding piece closes the battery replacement opening, which can prevent dust, debris and the like at the vehicle chassis from entering below the battery replacement opening and adversely affecting the battery replacement equipment below, which helps to reduce the cleaning pressure in the battery replacement channel. When the battery replacement vehicle completes the battery replacement, the shielding piece can also block the battery replacement opening to prevent the debris in the battery replacement station from interfering with the battery replacement equipment, providing stability protection for the work of the battery replacement equipment. Furthermore, the shielding piece moves in the horizontal direction to open or close the battery replacement opening, so that its movement path does not interfere with the battery replacement vehicle above and the battery replacement equipment below, providing a larger operating space for the battery replacement equipment below.

[0008] The battery replacement opening is provided with a bearing platform on both sides along the movement direction of the shielding piece, and the upper surface of the shielding piece is located on the same horizontal plane as the upper surface of the bearing platform.

[0009] The bearing platform can provide a support position for the wheels of the battery replacement vehicle. When the battery replacement vehicle moves to the preset battery replacement position, the front wheels and rear wheels can be supported on the two bearing platforms, respectively, to provide stable support for the battery replacement vehicle, thereby providing stability protection for the battery replacement work. On this basis, the upper surface of the shielding piece is arranged to be located on the same horizontal plane as the upper surface of the bearing platform, so that the vehicle does not experience the jerk caused by the up-down misalignment when passing through the shielding piece when entering or leaving the battery replacement station, thereby making the vehicle entry and exit more stable and helping to increase the user's battery replacement experience.

[0010] The bottom of the shielding piece is provided with a moving piece, the sidewall of the bearing platform is provided with a guide rail extending along the length direction thereof, the guide rail is located below the moving piece and cooperates with the moving piece to enable the shielding piece to move along the guide rail to close or open the battery replacement opening.

[0011] By setting the moving piece and the guide rail, on the one hand, the shielding piece can be driven by the moving piece to move along the guide rail, which improves the smoothness of the shielding piece opening or closing the battery swap opening, reduces the waiting time required for the battery swap vehicle to wait for the shielding piece to move to open the battery swap opening after reaching the position, and improves the battery swap efficiency; on the other hand, the setting of the guide rail provides a guiding effect for the movement of the shielding piece, so that the shielding piece can move along the extension direction of the guide rail to open or close the battery swap opening, thereby reducing the probability of the shielding piece being stuck with the side wall of the battery swap opening due to movement deviation, and improving the stability of the battery swap work.

[0012] The bottom of the shielding piece is provided with support plates arranged at intervals, and support shafts fixedly connected with the two support plates respectively, the moving piece is located between the two support plates, and the support shafts pass through the moving piece in the axial direction of the moving piece, so that the moving piece rotates around the support shafts.

[0013] The moving piece moves along the guide rail by rotating around the support shafts, that is, the moving piece and the guide rail are in rolling friction during the movement of the shielding piece, which greatly reduces the frictional resistance during the movement of the shielding piece and improves the smoothness of the movement of the shielding piece; in addition, the support plates at the bottom of the shielding piece not only provide the function of support shafts for the moving piece, but also support the shielding piece, which has high functional integration and optimizes the structural design of the opening and closing device.

[0014] The moving piece is a groove wheel, the groove wheel has limiting plates on both sides, a limiting recess is formed between the two limiting plates, and the two limiting plates are located on both sides of the guide rail so that the guide rail at least partially matches the limiting recess to facilitate the movement of the groove wheel along the guide rail.

[0015] By setting the limiting plates, the limiting plates respectively abut against both sides of the guide rail, which can prevent the groove wheel from moving deviation during the movement along the guide rail, and the cooperation of the limiting recess and the guide rail enables the groove wheel to stably roll along the extension direction of the guide rail, thereby stably opening or closing the battery swap opening, and avoiding the shielding piece from being stuck during the movement.

[0016] The opening and closing device further comprises limiting pieces arranged on the side walls on both sides of the shielding piece in the moving direction, and the side walls of the bearing platform are provided with limiting grooves consistent with the extension direction of the guide rail, and the limiting pieces can move along the extension direction of the limiting grooves to guide the movement of the shielding piece along the guide rail.

[0017] By setting the limiting grooves and the limiting pieces on both sides of the moving direction of the shielding piece, the shielding piece can move along the guide rail under the guiding action of the limiting pieces and the limiting grooves, which further reduces the possibility of movement deviation of the moving piece, thereby further improving the smoothness of the movement of the shielding piece.

[0018] The limiting piece comprises a plurality of limiting rollers arranged at intervals, and the limiting rollers are respectively in abutment with the top wall and the bottom wall of the limiting groove; and / or the limiting groove is located above the guide rail.

[0019] The limiting piece is provided as a limiting roller, which can reduce the frictional resistance between the limiting roller and the limiting groove during the movement of the limiting roller in the limiting groove, thereby reducing the frictional force suffered by the shielding piece during the movement of the shielding piece, and helping to improve the smoothness of the movement of the shielding piece. On this basis, the number of limiting rollers is set to be multiple, which can improve the limiting effect of the limiting rollers on the shielding piece. The limiting groove is arranged above the guide rail, so that the limiting groove and the guide rail are arranged in a staggered manner and do not conflict with each other in the transverse space, thereby optimizing the structural layout of the opening and closing device.

[0020] The shielding piece comprises a first baffle and a second baffle arranged in sequence along the moving direction, and the opposite sides of the first baffle and the second baffle are respectively provided with corresponding driving mechanisms. The driving mechanisms drive the first baffle and the second baffle to move in opposite directions to open or close the battery replacement opening.

[0021] The shielding piece is provided as a first baffle and a second baffle, and the driving mechanisms are respectively arranged on the opposite sides of the first baffle and the second baffle. The first baffle and the second baffle move synchronously to open or close the battery replacement opening, thereby shortening the movement stroke of each of the first baffle and the second baffle, and enabling the battery replacement opening to be opened or closed more quickly. Meanwhile, the first baffle and the second baffle move in opposite directions, which can uniformly occupy the space on both sides of the battery replacement opening, thereby reducing the demand for the space on one side of the battery replacement opening and optimizing the spatial layout of the opening and closing device.

[0022] The driving mechanism comprises a driving piece and a transmission piece connected between the driving piece and the shielding piece. The driving piece can drive the transmission piece to extend or retract to drive the shielding piece to move in the horizontal direction.

[0023] The transmission piece extends or retracts to drive the shielding piece to move, so that the driving piece requires a smaller working space when driving the shielding piece to move, and the driving piece itself is stationary when driving the shielding piece to move, and only the transmission piece extends or retracts to drive the shielding piece to move. In this way, the stability of the driving piece when working can be improved, and the shielding piece can be opened or closed to the battery replacement opening under the stable driving of the driving piece.

[0024] The transmission piece comprises a plurality of sequentially hinged scissor groups, and each scissor group comprises an inner arm and an outer arm hinged to each other. The inner arms and the outer arms of adjacent two scissor groups are hinged to each other, respectively.

[0025] The driving member drives the shielding member to move in real time with higher efficiency through the sequentially hinged scissors groups, and the telescopic movement of the scissors groups realizes the telescopic movement of the driving member, so that the driving member has higher structural stability, and the driving member drives the shielding member to the position more accurately, so that the shielding member can be accurately stopped at the preset position. In addition, the number of scissors groups can be adjusted according to the setting position of the driving member and the stroke demand of the shielding member, for example, when the driving member is far away from the shielding member or the shielding member, the number of scissors groups can be increased to improve the movement stroke of the shielding member driven by the driving member.

[0026] The driving mechanism includes a mounting frame, the driving member is mounted on the mounting frame, the mounting frame is provided with a guide sliding rail, the output end of the driving member is provided with a first guide member capable of sliding along the guide sliding rail, and the outer arm of the scissors group close to the driving member is hinged to the mounting frame and the inner arm is hinged to the first guide member; and / or the shielding member is provided with a guide sliding groove, the inner arm of the scissors group close to the shielding member is hinged to the shielding member and the outer arm is hinged to a second guide member located in the guide sliding groove.

[0027] The mounting frame provides a mounting position for the driving member, so that the driving member can stably drive the shielding member, and the guide sliding rail of the mounting frame and the first guide member at the end of the driving member provide movement guide for the inner arm of the scissors group connected to the driving member, so that the inner arm of the scissors group can move towards or away from the outer arm under the guide of the first guide member and the guide sliding rail, providing stability for the telescopic movement of the scissors group. Similarly, the guide sliding groove on the shielding member and the second guide member also provide movement guide for the telescopic movement of the inner arm and the outer arm of the scissors group connected to the shielding member, so that the outer arm of the scissors group can move towards or away from the inner arm along the extension direction of the guide sliding rail under the action of the second guide member, realizing the stable telescopic movement of the scissors group and further improving the driving stability of the shielding member.

[0028] A vehicle carrying platform includes a bearing platform and an opening and closing device as described above, the bearing platform has two, the two bearing platforms are arranged at intervals and form the battery replacement opening in the middle, and the driving mechanism drives the shielding member to move along the extension direction of the bearing platform to close or open the battery replacement opening.

[0029] The vehicle carrying platform of the present application includes two bearing platforms arranged at intervals, and the two bearing platforms are used to accommodate the battery replacement equipment. The battery replacement equipment takes and places the battery pack of the battery replacement vehicle through the upper battery replacement opening, and the opening and closing device can open or close the battery replacement opening, ensuring that the battery replacement vehicle drives and the battery replacement opening is closed after the battery replacement vehicle drives away, and the battery replacement equipment has good sealing performance.

[0030] A battery swap station comprises a battery swap device, a charging rack, and a carrying platform as described above.

[0031] The battery swap station of the present application realizes the closure of the battery swap opening during the entry and exit of the battery swap vehicle, greatly improving the user's battery swap experience.

[0032] Thanks to the above technical solutions, the present application has the following advantages:

[0033] 1. The opening and closing device of the present application can open or close the battery swap opening. When the battery swap vehicle is performing the battery swap operation, the vehicle needs to pass through the battery swap opening to reach the preset battery swap position. During the displacement of the vehicle, the shielding member closes the battery swap opening, so as to avoid the battery swap device below the battery swap opening from being exposed to the driver's field of view, and the driver does not need to exert additional attention to avoid the battery swap opening, greatly reducing the user's psychological pressure and helping to improve the user's battery swap experience. In addition, when the shielding member closes the battery swap opening, it can serve as a carrying platform for the battery swap vehicle to drive through, preventing the battery swap vehicle from falling off the battery swap opening due to vehicle deviation, and further improving the user's battery swap experience. During the passage of the vehicle, the shielding member closes the battery swap opening, which can prevent dust, debris, and the like at the vehicle chassis from entering below the battery swap opening and adversely affecting the battery swap device below, helping to reduce the cleaning pressure in the battery swap channel. When the battery swap vehicle completes the battery swap, the shielding member can also block the battery swap opening to prevent the battery swap station from being interfered with by debris, providing stability protection for the operation of the battery swap device.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0063] As Figure 1 , Figure 2As shown, an opening and closing device is installed above the battery replacement port 1 in the battery replacement station to open or close the battery replacement port 1. The opening and closing device includes a driving mechanism 2 and a shielding piece 3. The driving mechanism 2 drives the shielding piece 3 to move in the horizontal direction to close the battery replacement port 1 or open the battery replacement port 1.

[0064] The opening and closing device of the present application can open or close the battery replacement port 1. When the battery replacement vehicle performs the battery replacement operation, the vehicle needs to pass through the battery replacement port 1 to reach the preset battery replacement position. During the displacement of the vehicle, the shielding piece 3 closes the battery replacement port 1, so that the battery replacement equipment below the battery replacement port 1 is avoided from being exposed to the driver's field of view. The driver does not need to exert additional attention to avoid the battery replacement port 1, which greatly reduces the psychological pressure of the user and helps to increase the user's battery replacement experience. In addition, when the shielding piece 3 closes the battery replacement port 1, it can serve as a bearing platform 4 for the battery replacement vehicle to drive through, preventing the battery replacement vehicle from falling from the battery replacement port 1 due to vehicle deviation, further improving the user's battery replacement experience. During the passage of the vehicle, the shielding piece 3 closes the battery replacement port 1, which can avoid dust, debris and the like at the vehicle chassis from entering below the battery replacement port 1 and adversely affecting the battery replacement equipment below, which helps to reduce the cleaning pressure in the battery replacement passage. When the battery replacement vehicle completes the battery replacement, the shielding piece 3 can also block the battery replacement port 1 to prevent the battery replacement station from interfering with the battery replacement equipment, providing stability protection for the work of the battery replacement equipment. Furthermore, the shielding piece 3 moves in the horizontal direction to open or close the battery replacement port 1, so that its movement path does not interfere with the battery replacement vehicle above and the battery replacement equipment below, providing a larger operating space for the battery replacement equipment below.

[0065] Specifically, a battery replacement passage is provided below the battery replacement port 1, and a battery replacement equipment is arranged in the battery replacement passage. In one embodiment, the battery replacement equipment can move back and forth along the battery replacement passage and transport battery packs. After the battery pack at the bottom of the battery replacement vehicle is disassembled, the battery replacement equipment transports it to the charging rack 120 in the battery replacement station, and can transport the full battery pack on the charging rack 120 to the bottom of the battery replacement vehicle and install it. In another embodiment, the battery replacement equipment is located below the battery replacement port 1 and cannot move in the battery replacement passage. An additional moving device is provided for the battery replacement equipment to transport battery packs. The battery replacement equipment can remove the battery pack at the bottom of the battery replacement vehicle, then transport the battery pack to the charging rack 120 in the battery replacement station through the moving device, and receive the full battery pack transported by the moving device and install it at the bottom of the battery replacement vehicle.

[0066] As a preferred embodiment of the present application, as shown in Figure 1 、 Figure 2As shown, the battery replacement opening 1 is provided with a bearing platform 4 on both sides along the moving direction of the shielding piece 3, and the upper surface of the shielding piece 3 is located on the same horizontal plane as the upper surface of the bearing platform 4. The bearing platform 4 can provide a support position for the wheels of the battery replacement vehicle, and when the battery replacement vehicle moves to the preset battery replacement position, the front wheels and rear wheels thereof can be supported on the two bearing platforms 4 respectively, thereby providing stable support for the battery replacement vehicle and ensuring the stability of the battery replacement work. On this basis, the upper surface of the shielding piece 3 is arranged on the same horizontal plane as the upper surface of the bearing platform 4, so that when the battery replacement vehicle enters or exits the battery replacement station, it will not experience the jerk caused by the up-down misalignment when passing through the shielding piece 3, thereby making the vehicle enter and exit more smoothly and helping to improve the user's battery replacement experience.

[0067] As a preferred embodiment of the present embodiment, as shown in Figure 3 , Figure 4 As shown, the bottom of the shielding piece 3 is provided with a moving piece 5, the sidewall of the bearing platform 4 is provided with a guide rail 6 extending along the length direction thereof, and the guide rail 6 is located below the moving piece 5 and cooperates with the moving piece 5 to enable the shielding piece 3 to move along the guide rail 6 to close or open the battery replacement opening 1. By arranging the moving piece 5 and the guide rail 6, on the one hand, the shielding piece 3 can be driven by the moving piece 5 to move along the guide rail 6, thereby improving the smoothness of the shielding piece 3 in opening or closing the battery replacement opening 1, reducing the waiting time required for the battery replacement vehicle to wait for the shielding piece 3 to move to open the battery replacement opening 1 after reaching the position, and improving the battery replacement efficiency; on the other hand, the arrangement of the guide rail 6 provides a guiding effect for the movement of the shielding piece 3, so that the shielding piece 3 can move along the extension direction of the guide rail 6 to open or close the battery replacement opening 1, thereby reducing the probability of jamming with the sidewall of the battery replacement opening 1 caused by the movement deviation of the shielding piece 3, and improving the stability of the battery replacement work.

[0068] The structure of the moving piece 5 is not limited in the present embodiment, and any one of the following examples can be adopted:

[0069] As shown in Figure 4 , the bottom of the shielding piece 3 is provided with spaced-apart support plates 31, and support shafts 32 are fixedly connected to the two support plates 31 respectively, the moving piece 5 is located between the two support plates 31, and the support shafts 32 are arranged through the moving piece 5 along the axial direction of the moving piece 5 to enable the moving piece 5 to rotate around the support shafts 32. The guide rail 6 is arranged in a rectangular strip structure, and the moving piece 5 moves along the guide rail 6 by rotating around the support shafts 32, that is, the rolling friction between the moving piece 5 and the guide rail 6 during the movement of the shielding piece 3 greatly reduces the frictional resistance during the movement of the shielding piece 3, thereby improving the smoothness of the movement of the shielding piece 3; in addition, the support plates 31 at the bottom of the shielding piece 3 not only provide the function of the support shafts 32 for the moving piece 5, but also support the shielding piece 3, thereby achieving high integration of functions and optimizing the structural design of the opening and closing device.

[0070] In the second example, the guide rail is configured as a round rod extending along the length direction of the bearing platform, and the moving member is configured as a linear bearing sleeved outside the round rod or the moving member is configured as an arc structure clamped above the round rod. In this way, the linear bearing is used as the moving member, which can reduce the frictional resistance of the moving member when moving along the guide rail, thereby reducing the frictional resistance of the shielding member when moving, and helping to improve the smoothness of the movement of the shielding member.

[0071] As a preferred mode of the first example, as shown in Figure 4 The bottom of the shielding member 3 is provided with a mounting plate 35, and the support plate 31 is connected to the mounting plate 35. In this way, the stress area of the shielding member 3 can be improved, and the possibility of stress concentration at the connection between the shielding member 3 and the support plate 31 can be reduced.

[0072] As another preferred mode of the first example, as shown in Figure 4 The moving member 5 is a groove wheel 51, the groove wheel 51 is provided with limiting plates 52 on both sides, a limiting recess 53 is formed between the two limiting plates 52, and the two limiting plates 52 are located on both sides of the guide rail 6 so that the guide rail 6 at least partially fits into the limiting recess 53 to facilitate the movement of the groove wheel 51 along the guide rail 6. By arranging the limiting plates 52 to abut against the two sides of the guide rail 6, the movement of the groove wheel 51 can be prevented from being deviated during movement along the guide rail 6. The cooperation between the limiting recess 53 and the guide rail 6 enables the groove wheel 51 to stably roll along the extension direction of the guide rail 6, thereby stably opening or closing the battery replacement opening 1. It should be noted that the phrase "the guide rail 6 at least partially fits into the limiting recess 53" does not mean that the guide rail 6 abuts against the limiting plates 52, but rather there is a certain short distance between the limiting plates 52 and the guide rail 6. In this way, the limiting plates 52 can avoid friction with the guide rail 6 in the normal movement state of the moving member 5.

[0073] Preferably, as shown in Figure 5 The opening and closing device further includes limiting members 7 arranged on the side walls of the shielding member 3 along the movement direction. The side walls of the bearing platform 4 are provided with limiting grooves 41 extending in the same direction as the guide rail 6, and the limiting members 7 can move along the extension direction of the limiting grooves 41 to guide the movement of the shielding member 3 along the guide rail 6. By arranging the limiting grooves 41 and the limiting members 7 on both sides of the movement direction of the shielding member 3, the shielding member 3 can move along the guide rail 6 under the guidance of the limiting members 7 and the limiting grooves 41, further reducing the possibility of movement deviation of the moving member 5, and further improving the smoothness of the movement of the shielding member 3.

[0074] Further, as shown in Figure 5As shown, the limiting member 7 includes a plurality of limiting rollers arranged at intervals, and the limiting rollers are respectively in abutment with the top wall and the bottom wall of the limiting groove 41. The limiting member 7 is arranged as a limiting roller, which can reduce the frictional resistance between the limiting member 7 and the limiting groove 41 during the movement of the limiting member 7 in the limiting groove 41, thereby reducing the frictional force borne by the shielding member 3 during the movement of the shielding member 3, and helping to improve the smoothness of the movement of the shielding member 3. On this basis, the number of limiting rollers is arranged to be multiple, which can improve the limiting effect of the limiting rollers on the shielding member 3.

[0075] Further, as shown in Figure 3 , the limiting groove 41 is located above the guide rail 6. Arranging the limiting groove 41 above the guide rail 6 enables the limiting groove 41 and the guide rail 6 to be arranged in a staggered manner and not to conflict with each other in the transverse space, thereby optimizing the structural layout of the opening and closing device.

[0076] Preferably, as shown in Figure 4 , Figure 5 , the bottom of the shielding member 3 is provided with a connecting member 36 extending along the movement direction of the shielding member 3, the connecting member 36 is in the shape of a hollow square column, the limiting rollers are installed on the side wall of the connecting member 36, and the moving member 5 is installed on the bottom wall of the connecting member 36.

[0077] As a preferred embodiment of the present application, as shown in Figure 1 , Figure 2 , the shielding member 3 includes a first baffle 33 and a second baffle 34 arranged in sequence along the movement direction, and the side away from the first baffle 33 and the second baffle 34 is respectively provided with a corresponding driving mechanism 2, and the driving mechanism 2 drives the first baffle 33 and the second baffle 34 to move in opposite directions to open or close the battery replacement opening 1. Arranging the shielding member 3 to include the first baffle 33 and the second baffle 34 and arranging the driving mechanism 2 on the side away from the first baffle 33 and the second baffle 34 enables the first baffle 33 and the second baffle 34 to move synchronously to open or close the battery replacement opening 1, thereby shortening the movement stroke of each of the first baffle 33 and the second baffle 34, and enabling the battery replacement opening 1 to be opened or closed more quickly. Meanwhile, the first baffle 33 and the second baffle 34 move in opposite directions respectively, which can uniformly occupy the space on both sides of the battery replacement opening 1, thereby reducing the demand for the space on one side of the battery replacement opening 1 and optimizing the spatial layout of the opening and closing device.

[0078] The present application does not limit the structural form of the shielding member, and in another embodiment, the shielding member can also be a plate-shaped structure, and the plate-shaped structure is driven by the driving mechanism 2 to open or close the battery replacement opening 1.

[0079] The present application does not limit the structural form of the driving mechanism 2 and the relative positional relationship between the shielding plate, and any one of the following embodiments can be adopted:

[0080] Embodiment one: as shown in Figure 1 , Figure 2As shown, the driving mechanism 2 comprises a driving member 21 and a transmission member 22 connected between the driving member 21 and the shielding member 3, the driving member 21 can drive the transmission member 22 to extend or retract to drive the shielding member 3 to move in the horizontal direction. The transmission member 22 extends or retracts to drive the shielding member 3 to move, so that the working space required by the driving member 21 to drive the shielding member 3 to move is small, and the driving member 21 is stationary when driving the shielding member 3 to move, and only relies on the extension and retraction of the transmission member 22 to drive the shielding member 3 to move. In this way, the stability of the driving member 21 when working can be improved, and then the shielding member 3 can be opened or closed under the stable driving of the driving member 21.

The transmission member 22 is formed by the sequentially hinged scissor groups 221, so that the real-time performance and movement efficiency of the transmission member 22 driving the shielding member 3 to move are higher, and the extension and retraction of the transmission member 22 is realized by the extension and retraction of the scissor group 221, so that the transmission member 22 has higher structural stability, and the position of the shielding member 3 driven by the driving member 21 is more accurate, and the shielding member 3 can be accurately stopped at the preset position; in addition, the number of scissor groups 221 can be adjusted according to the setting position of the driving member 21 and the stroke demand of the shielding member 3, for example, when the driving member 21 is far away from the shielding member 3 or the shielding member 3, the number of scissor groups 221 can be increased to improve the movement stroke of the shielding member 3 driven by the driving member 21.

[0083] Specifically, in the embodiment, the driving member 21 comprises a driving shaft, and the extension direction of the driving shaft is perpendicular to the extension direction of the shielding member 3, and the driving member 21 controls the extension and retraction of the driving shaft to drive the transmission member 22 to extend or retract.

The guide sliding rail 8 of the mounting frame 23 and the first guide piece 10 at the end of the driving piece 21 provide movement guidance for the inner arm 2211 of the scissor group 221 connected to the driving piece 21, so that the inner arm 2211 of the scissor group 221 can move towards or away from the outer arm 2212 under the guidance of the first guide piece 10 and the guide sliding rail 8, which provides stability guarantee for the extension and contraction of the scissor group 221. Similarly, the guide sliding groove 9 and the second guide piece 110 on the shielding piece 3 also provide movement guidance for the extension and contraction of the inner arm 2211 and the outer arm 2212 of the scissor group 221 connected to the shielding piece 3, so that the outer arm 2212 of the scissor group 221 can move towards or away from the inner arm 2211 along the extension direction of the guide sliding rail 8 under the action of the second guide piece 110, realizing the stable extension and contraction of the scissor group 221 and further improving the driving stability of the shielding piece 3.
