[0085] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0086] Example 1

[0087] like Figure 1-Figure 5 As shown, the present invention discloses a channel opening and closing device for a battery swap station. The battery swap station of this embodiment may include a battery swap platform, a charging compartment and a battery swap device. The charging compartment is arranged on at least one side of the battery swap platform perpendicular to the driving direction of the electric vehicle. The battery swap device travels back and forth between the battery swap platform and the charging compartment to exchange batteries. The battery swap station also includes a channel opening for the battery swap device to enter and exit the charging compartment. The channel opening is provided with a channel opening and closing device, which is used to open or close the channel opening. Of course, in other embodiments, this embodiment can be applied to other types of battery swap stations or charging stations to open and close the channel opening.

[0088] The channel opening and closing device of this embodiment is used for opening and closing the channel opening of the battery exchange equipment in the battery exchange station, such as Figure 1 As shown, the passage opening and closing device includes: a mounting portion 100, a lifting portion 200 and a driving portion 300, wherein the lifting portion 200 is installed on the battery swap station through the mounting portion 100, and the driving portion 300 drives the lifting portion 200 to rise and fall relative to the mounting portion 100 to open or close the passage opening. The mounting portion 100 is automatically driven to rise and fall by the driving portion 300, so that the entry and exit passage opening can be opened according to the entry and exit needs of the battery swap equipment. Therefore, the passage opening and closing device can keep the battery swap station airtight when not in operation, ensure that the battery compartment is isolated from the outside world, will not be damaged by the outside world, and the internal temperature control is more stable. At the same time, it can be automatically opened in the working state to ensure the entry and exit of the battery swap equipment.

[0089] The driving unit 300 includes a transmission rod and a power source, the power source is connected to one end of the transmission rod 320, and the other end of the transmission rod is connected to the lifting unit 200. The driving unit 300 adopts the structure of the transmission rod, and the transmission rod is driven by the power source to drive the lifting unit 200. The structure is relatively simple and durable, with a long service life, and the internal space of the battery swap station is small. The driving structure of the transmission rod can drive a heavy door panel, and the applicability is good.

[0090] In a preferred embodiment, Figure 2 As shown, the transmission rod is a piston rod, the power source includes a cylinder 310, and the mounting portion 100 includes a cylinder bracket 510 for fixing the cylinder 310. The lifting portion 200 is provided with a mounting bracket 520, and the mounting bracket 520 is provided with a piston rod connecting portion 530, and the transmission rod 320 is connected to the piston rod connecting portion 530. Stable and reliable driving can be achieved through the piston rod and the cylinder 310. It can be understood that the driving portion is not limited to the pneumatic structure in this embodiment. In other optional embodiments, the power source can also include other structures such as a hydraulic cylinder and a motor to drive the transmission rod.

[0091] Among them, in one embodiment, the mounting portion 100 is connected to a box structure located between the battery swap compartment and the charging compartment in the battery swap station. In another embodiment, the battery swap station further includes box columns for installing the box of the battery swap station, and the side and top surfaces of the mounting portion 100 are connected to the box columns. In these two embodiments, the mounting portion 100 is directly connected to the partition structure between the battery swap compartment and the charging compartment, making full use of the original structure of the battery swap station. In addition, the lifting portion 200 occupies less internal space of the charging room, and the space at the rear of the lifting portion 200 is sufficient to accommodate the battery swap equipment, so the lifting portion 200 can be a flat structure. Of course, in other embodiments, the mounting portion 100 can also be connected to other structures for fixation.

[0092] like Figure 2 and Figure 3 As shown, in one embodiment, the lifting part 200 and the mounting part 100 are lifted relative to each other by means of a sliding shoe 210 and a sliding rail 400. The sliding shoe 210 is slidably connected to the sliding rail 400. The movement guidance of the lifting part 200 can be achieved by means of the sliding shoe 210 and the sliding rail 400. The sliding shoe 210 can be arranged on the lifting part 200 or the mounting part 100, and the sliding rail 400 can be correspondingly arranged on the mounting part 100 or the lifting part 200. Of course, in other embodiments, other structures can also be used to achieve relative lifting, such as guide wheels, sliders and other structures.

[0093] like Figure 4As shown, in one embodiment of the sliding shoe 210, the sliding shoe 210 and the sliding rail 400 have a sliding surface on one side where they slide together. The sliding surface of the sliding shoe 210 and / or the sliding rail 400 is made of a polymer material. For example, the sliding surface can be made of polyethylene, polytetrafluoroethylene, ceramic composite material, etc. The sliding surface of the polymer material is smoother, which reduces the resistance during sliding, and has good wear resistance and a long service life. The sliding surface can be set on the surface of the side where the sliding shoe 210 and the sliding rail 400 cooperate by gluing, riveting or clamping. In other embodiments, a sliding surface of other lubricating materials can also be set.

[0094] like Figure 4 As shown in FIG. 1 , in another embodiment of the sliding shoe 210, a sliding groove 211 is provided on the sliding shoe 210, and the slide rail 400 has a matching portion 420, wherein the matching portion 420 is inserted into the sliding groove 211 and slidably matches with the sliding groove 211. The sliding groove 211 can be nested with the matching portion 420, so as to prevent the sliding groove 211 from falling out of the matching portion during sliding. Figure 4 As shown, further, a guide surface 213 is provided on the slide shoe 210, and the slide rail 400 passes through the guide surface 213 and slides with the slide groove 211. The cross-sectional dimension of the guide surface 213 in the sliding direction of the slide rail 400 gradually narrows from large to small until it is narrowed to the same cross-sectional dimension as the slide groove 211, and is connected to the slide groove 211, thereby guiding the slide rail 400 to gradually slide into the slide groove 211.

[0095] like Figure 3 As shown, in one embodiment of the slide rail 400, the slide rail 400 is an L-shaped bent plate, one end of the L-shaped slide rail 400 has a matching portion 420, and the other end is a fixed portion 410 fixedly connected to the mounting portion 100. Preferably, the fixing bracket 110 on the mounting portion 100 is connected to the fixed portion 410 at the other end of the slide rail 400. The L-shaped bent plate structure of the slide rail 400 is simple and is also conducive to installation and fixation. In other embodiments, the slide rail 400 can also adopt other forms, such as I-shaped, straight-line and other known shapes.

[0096] like Figure 2 As shown, in one embodiment, the passage opening and closing device further includes a detection device, which may be a travel switch 700. The travel switch 700 is disposed on the mounting portion 100. When the lifting portion 200 rises to a preset position, the travel switch 700 contacts the lifting portion 200 to detect whether the lifting portion 200 is in place. The travel switch 700 detects the lifting position of the lifting portion 200, thereby determining whether the lifting portion 200 is in place, which is conducive to automatic control.

[0097] like Figure 1 and Figure 2As shown, in one embodiment, the mounting portion 100 is further provided with a functional opening, and the number of the functional openings may be one or more. In this embodiment, the functional openings specifically include a functional opening 101 and a functional opening 102, and the functional openings 101 and the functional opening 102 are correspondingly provided with a cover plate 610 and a cover plate 620, and the cover plate 610 and the cover plate 620 are used to close or open the functional opening 101 and the functional opening 102. The functional openings 101 and the functional openings 102 can be used to inspect and repair the interior of the passage opening and closing device without disassembling the passage opening and closing device.

[0098] In a further preferred embodiment, one end of the cover plate 610 and / or the cover plate 620 is locked to the mounting portion 100 by a locking mechanism 720, and the other end of the cover plate 610 and / or the cover plate 620 is hingedly connected to the mounting portion 100. The cover plate can be locked by the locking mechanism 720 to prevent the cover plate from being accidentally opened or opened by unnecessary personnel. In other embodiments, the cover plate 610 and / or the cover plate 620 can also be fixed to the mounting portion 100 by other means such as threaded connection, clamping, etc.

[0099] One embodiment of the lock mechanism 720 includes a lock body and a swing rod that moves relative to the lock body. The lock body is installed on the inner side of the mounting portion 100 through a lock bracket. The swing rod cooperates with the mounting portion 100 and locks or unlocks the cover plate by swinging the swing rod. The cooperation between the swing rod and the mounting portion 100 can be that the swing rod directly clamps the frame of the opening on the mounting portion 100, or a matching portion corresponding to the position of the swing rod can be provided on the mounting portion 100 to achieve a more secure cover plate locking effect. Of course, in other optional embodiments, the lock mechanism 720 can also be other types of structures that can lock the cover plate, such as a latch, a lock tongue, etc.

[0100] In a further preferred embodiment, the functional opening 102 and the functional opening 101 serve as inspection ports. The functional opening 102 corresponds to the equipment component of the channel opening and closing device provided on the mounting portion 100, and the functional opening 101 corresponds to the equipment provided inside the battery swap station. Among them, in a preferred embodiment, the functional opening 102 is opened corresponding to the position of the travel switch 700 and the single valve 710 on the mounting portion 100, and the travel switch 700 and the single valve 710 are both fixed to the mounting portion 100 through a mounting bracket, and the single valve 710 is used to control the movement of the driving portion 300, and the single valve 710 can generally be a solenoid valve device. Since the travel switch 700 and the single valve 710 are arranged in a relatively compact position, the area of ​​the functional opening 102 is relatively small, and the cover plate 620 can preferably be directly fixed to the mounting portion 100 using threaded fasteners to save space and avoid conflicts. The functional opening 101 is opened corresponding to the position of the control cabinet in the battery swap station. Since the volume of the control cabinet is relatively large, the number of the functional openings 101 is two and the area is relatively large. One end of each cover plate 610 is hingedly connected to the mounting portion 100 , and the other end is locked to the mounting portion 100 via two locking mechanisms 720 , so that the cover plate 610 is firmly locked.

[0101] In a preferred embodiment, the power station includes an air compressor and an air pipe, and the air compressor provides gas to the cylinder 310 through the air pipe. The air pipe includes a main air pipe and a bronchial pipe, the main air pipe is connected to the air compressor, one end of the bronchial pipe is connected to the main air pipe through a single valve 710, and the other end is connected to the cylinder 310.

[0102] In a battery swap station, when charging compartments are provided on both sides of the battery swap platform, passage openings and corresponding passage opening opening and closing devices are provided on both sides of the battery swap platform. In order to save the internal space of the battery swap station, only one air compressor is generally provided in the battery swap station, and the air compressor is generally provided in the charging compartment on one side of the battery swap platform. The air compressor is connected to the single valve 710 on the passage opening and closing devices on both sides through two main air pipes, and the single valve 710 on the passage opening and closing devices on each side is connected to the cylinder 310 of the driving unit 300 through a bronchial tube to control the operation of the cylinder 310, thereby controlling the lifting and lowering of the passage opening and closing device.

[0106] Example 2

[0107] This embodiment discloses another embodiment of a channel opening and closing device. In this embodiment, the same or similar configurations as those in Embodiment 1 are not described in detail. Figure 6 and Figure 7 As shown, the passage opening and closing device also includes: a mounting part 100, a lifting part 200 and a driving part 300, wherein the lifting part 200 is installed at the battery swap station through the mounting part 100, and the driving part 300 drives the lifting part 200 to rise and fall relative to the mounting part 100 to open or close the passage. The driving part 300 automatically drives the mounting part 100 to rise and fall, thereby opening the passage according to the entry and exit needs of the battery swap equipment.

[0108] The lifting part 200 and the mounting part 100 are lifted and lowered relative to each other through the sliding shoe 210 and the sliding rail 400, and the sliding shoe 210 is slidably connected to the sliding rail 400. The driving part 300 includes a transmission rod and a power source. In this embodiment, the transmission rod can be preferably a piston rod, and the power source includes a cylinder 310. The lifting part 200 includes a door panel, wherein the sliding rail 400 is connected to the charging rack in the battery swap station through the mounting part 100, the sliding shoe 210 is installed on the door panel, the cylinder 310 is installed on the charging rack, and the piston rod is installed at the bottom of the back of the door panel.

[0109] like Figure 6 and Figure 7As shown, the installation position of the passage opening and closing device of this embodiment is different from that of embodiment 1 in that the installation part 100 of this embodiment is fixed on the charging rack 101 located in the charging compartment, and the charging rack 101 is used to charge and discharge the battery, and includes a column 110, a fixing bracket 120 and a beam 130. The installation part 100 is fixed on the column 110 and / or the beam 130 of the charging rack 101.

[0110] Among them, Figures 6 to 8 As shown, in a preferred embodiment, this part of the mounting portion 100 of the fixed slide rail 400 is fixed on the column 110. This part of the mounting portion 100 of the fixed cylinder 310 is similar to the crossbeam 130, which is horizontally mounted on the columns 110 on both sides for fixing.

[0111] like Figure 8 and Fig. 9 As shown, in a preferred embodiment, the cylinder 310 is connected to one end of the piston rod, the other end of the piston rod is connected to the lifting part 200, the lifting part 200 is provided with a mounting bracket 520, the mounting bracket 520 is provided with a piston rod connecting part 530, and the other end of the piston rod is connected to the piston rod connecting part 530. Stable and reliable driving can be achieved through the piston rod and the cylinder 310.

[0112] like Fig. 9 As shown, in a preferred embodiment, the piston rod and the piston rod connecting portion 530 are rotatably connected via a rotating shaft 540. The arrangement of the rotating shaft 540 allows the piston rod to rotate with the piston rod connecting portion 530 when the piston rod is lifted, thereby reducing the sliding accuracy requirements for the lifting portion 200.

[0113] like Fig.10 and Fig.11 As shown, in a preferred embodiment, a flexible barrier component 900 is connected to the inner side of the lifting part 200, and the bottom of the flexible barrier component 900 exceeds the bottom of the lifting part 200. The flexible barrier component 900 can seal the bottom space of the lifting part 200, and at the same time, it can also prevent the lifting part 200 from contacting the ground, and can also absorb the impact when the lifting part 200 accidentally collides with the battery replacement equipment when it descends.

[0114] like Fig.10 and Fig.11 As shown, in a further preferred embodiment, the flexible blocking component 900 is a brush, which is embedded in the brush installation strip 230, wherein the brush installation strip 230 is connected to the inner side of the bottom of the lifting part 200. The brush can be installed and replaced through the brush installation strip 230. Of course, in other embodiments, the flexible blocking component 900 in other forms such as rubber plates and aluminum alloy strips can also be used.

[0115] like Fig.10 and Fig.11 As shown, in a further preferred embodiment, the bottom of the lifting part 200 has an outwardly protruding enclosure part 220, and the bottom of the enclosure part 220 is connected to a flexible blocking component 900. After the passage opening and closing device is preferably installed on the charging rack 101, compared with the passage opening and closing device in Example 1, the space inside the lifting part 200 in this embodiment is smaller, resulting in problems in accommodating the battery exchange equipment. Therefore, by protruding the enclosure part 220 outward, the space inside the protruding enclosure part 220 can accommodate the battery exchange equipment, and in the case of a narrow internal space, the battery exchange equipment protruding outward is protected.

[0116] like Fig.10 and Fig.11 As shown, in a further preferred embodiment, the flexible blocking component 900 is a brush, which is embedded in the brush mounting strip 230, wherein the brush mounting strip 230 extends along the bottom shape of the enclosure 220, and makes the brush form a semi-enclosed shape. The semi-enclosed brush is sealed from three directions to prevent debris from entering the enclosure 220, thereby preventing the debris from affecting the operation of the battery exchange device.

[0117] Example 3

[0118] This embodiment discloses another embodiment of a channel opening and closing device. In this embodiment, the same or similar configurations as those in Embodiment 1 or Embodiment 2 are not described in detail. Figure 12-14 As shown, the passage opening and closing device also includes: a mounting portion 100, a lifting portion 200 and a driving portion 300, wherein the lifting portion 200 is installed on the battery swap station through the mounting portion 100, and the driving portion 300 drives the lifting portion 200 to rise and fall relative to the mounting portion 100 to open or close the passage. The driving portion 300 includes a power source and a transmission rod. In this embodiment, the connection method of the power source and the transmission rod can be the same as that of Example 1 or Example 2, thereby automatically driving the lifting of the mounting portion 100 through the driving portion 300, thereby opening the passage according to the entry and exit needs of the battery swap equipment.

[0119] like Fig.13 As shown, the mounting part 100 of this embodiment is provided with a travel switch 700. As in the embodiment, when the lifting part 200 rises to the position, the upper end of the lifting part 200 contacts the travel switch 700, so that the travel switch 700 senses the position information, thereby controlling the driving part 300 to stop the lifting part 200 from continuing to rise. For example, in this embodiment, the transmission rod is preferably a piston rod, and the power source includes a cylinder 310. Then, the air path of the cylinder 310 can be cut off by controlling the single valve 710 to stop the lifting part 200 from rising.

[0120] In some embodiments, the mounting portion 100 is connected to a box structure located between the battery swap compartment and the charging compartment in the battery swap station. In another embodiment, if the battery swap station further includes a box column for mounting the box of the battery swap station, the side and top surface of the mounting portion 100 are connected to the box column. Among them, the internal structure can be repaired by disassembling the mounting portion 100 as a whole. A handle can be further provided on the outside of the mounting portion 100 and the lifting portion 200 for easy picking.

[0121] like Fig.12 As shown, in the preferred embodiment, the rubber pad 810 is strip-shaped, and the strip-shaped rubber pad 810 is respectively fixedly connected to the outer ends of the plurality of railing components 800. Thus, a continuous extension barrier can be achieved through a rubber pad 810, and the buffering area of ​​the rubber pad is increased, and the buffering effect is better.

[0122] like Fig.13 As shown, the lifting part 200 of this embodiment is a plate-shaped structure, and preferably a plurality of reinforcing ribs 220 are arranged on the lifting part 200. The reinforcing ribs 200 ensure the structural strength of the lifting part 200, and the arrangement of the reinforcing ribs 200 can be appropriate. For example, the reinforcing ribs 200 of this embodiment are distributed in both the horizontal and vertical directions, thereby enhancing the strength of the lifting part 200 in both the horizontal and vertical directions.

[0123] like Fig.13 as well as Fig.14 As shown, a guide hole 212 is provided on the slide shoe 210 of this embodiment, and the slide rail 400 passes through the guide hole and slides with the slide shoe 210. The guide hole 212 facilitates the entry of the slide rail 400 and plays a role in guiding and cooperating with the slide groove. The slide rail 400 is cylindrical, and one end of the cylindrical slide rail 400 passes through the guide hole 212, and the other end is fixedly connected to the mounting portion 100. Alternatively, the middle of the cylindrical slide rail 400 passes through the guide hole 212, and both ends are fixedly connected to the mounting portion 100. After the cylindrical slide rail 400 is matched with the guide hole 212, it can be constrained by the guide hole in all directions, thereby ensuring that no deviation and dislocation will occur during sliding, making the lifting process of the channel opening and closing device more stable.

[0124] like Fig.15 As shown, the present invention also discloses a battery replacement control method, which can be implemented using the channel opening and closing device in any of the above embodiments, including:

[0125] Step S101: After the vehicle enters the predetermined parking position of the battery swap station, a vehicle arrival signal is received.

[0126] Specifically, a vehicle arrival mechanism such as an arrival detection sensor and a wheel trigger mechanism can be set at a predetermined parking position in the battery swap station. After the vehicle enters and stops at the predetermined parking position, the vehicle arrival mechanism is triggered, and the vehicle arrival mechanism sends a vehicle arrival signal to the control device. The control device can preferably be set in the battery swap station and communicate with the vehicle arrival mechanism through buried lines or other wired or wireless methods.

[0127] Step S102: Send a driving control signal to control the driving part 300 to lift the lifting part 200 to open the passage opening.

[0128] Specifically, the control device is connected to the control device of the driving part 300 by wired or wireless means. For example, in this embodiment, the driving part adopts the structure of the cylinder 310 and the piston rod. The control device can send a driving control signal to the single valve 7100 connected to the cylinder 310 to control the single valve 710 to realize the action, so that the gas of the air compressor enters the cylinder 310 and lifts the lifting part 200 upward. After the lifting part 200 hits the travel switch 700, the cylinder stops lifting upward.

[0129] Step S103: After the battery replacement equipment returns to the charging compartment after replacing the battery, it receives a battery replacement arrival signal.

[0130] Specifically, an origin sensor can be set in the battery swap room of the battery swap station. After the battery swap equipment completely enters the charging compartment, that is, after all the battery swap equipment passes through the passage, the origin sensor is triggered. The origin sensor sends a battery swap arrival signal to the control device. At this time, the descent of the lifting part 200 will not collide with the battery swap equipment.

[0131] Step S104: sending a driving control signal to control the driving part 300 to lower the lifting part 200 to close the passage opening.

[0132] Specifically, the control device is connected to the single valve 710 by wire or wireless means, and after sending the driving control signal, the single valve 710 realizes the reverse action, so that the gas of the air compressor enters the cylinder 310 and descends the lifting part 200. After the complete descent, the passage is closed, and the external debris cannot enter the battery swap station.

[0133] It is understandable that the battery swap control method provided in the embodiment of the present invention can be implemented by means of software and necessary general hardware, and of course can also be implemented by hardware. Generally, the method described in the present invention can be executed by a control device set in a battery swap station, and the control device can be a programmable logic controller or a computer device, etc.
