[0041] The present application provides a battery testing device, which includes a sealed door 1000 and a cabinet, wherein the sealed door 1000 is rotatably connected to the cabinet to realize opening and closing of the cabinet. It should be noted that the battery testing device here can be a formation device, a capacity separation device, etc., and of course it can also be other battery testing devices in a battery production line.

[0042] Figure 1 This is a schematic diagram of a sealing door 1000 in a closed state provided according to one embodiment of the present application. Figure 2 for Figure 1 Schematic diagram of the sealing door 1000 in the open state.

[0043] See also Figure 1 and Figure 2 The sealing door 1000 includes a movable door assembly 100, an opening and closing mechanism 200 and a door panel assembly 300. The movable door assembly 100 is located on one side of the door panel assembly 300 in the thickness direction, the opening and closing mechanism 200 is connected to the door panel assembly 300, and the movable door assembly 100 is connected to the opening and closing mechanism 200.

[0044] The door panel assembly 300 is provided with a door opening H1, and the opening and closing mechanism 200 is used to drive the movable door assembly 100 to move between an open position and a closed position. In the open position, the movable door assembly 100 opens the door opening H1. In the closed position, the movable door assembly 100 closes the door opening H1.

[0045] When the movable door assembly 100 moves from the open position to the closed position, the distance between the movable door assembly 100 and the door panel assembly 300 in the thickness direction gradually decreases.

[0046] It should be understood that when the movable door assembly 100 is in the open position, the sealing door 1000 is in the open state. When the movable door assembly 100 is in the closed position, the sealing door 1000 is in the closed state.

[0047] In this embodiment, the movable door assembly 100 and the door panel assembly 300 are arranged side by side in the thickness direction, and the movable door assembly 100 is movably connected to the door panel assembly 300 through the opening and closing mechanism 200. Under the action of the opening and closing mechanism 200, the movable door assembly 100 can move relative to the door panel assembly 300 to achieve movement between a closed position and an open position, thereby opening or closing the door opening H1, that is, achieving switching between a closed state and an open state.

[0048] When the sealing door 1000 switches from an open state to a closed state, the movable door assembly 100 moves from an open position toward a closed position, and the distance between the movable door assembly 100 and the door panel assembly 300 in the thickness direction gradually decreases until the movable door assembly 100 is completely close to the door panel assembly 300. At this time, the movable door assembly 100 is in a closed position.

[0049] It should be understood that when the movable door assembly 100 is in the closed position, under the continued driving of the opening and closing mechanism 200, the movable door assembly 100 still has a tendency to continue to move. However, due to the obstruction of the door panel assembly 300, the movable door assembly 100 cannot continue to move. At this time, a large pre-tightening force is formed between the movable door assembly 100 and the door panel assembly 300 to ensure the sealing performance, thereby improving the thermal insulation capacity of the battery testing equipment.

[0050] It should be understood that when the sealing door 1000 switches from the closed state to the open state, the movable door assembly 100 moves from the closed position to the open position, and accordingly, the distance between the movable door assembly 100 and the door panel assembly 300 in the thickness direction gradually increases. At this time, the movable door assembly 100 and the door panel assembly 300 are spaced apart in the thickness direction, and the movable door assembly 100 fully opens the door opening H1.

[0051] It should be noted that the thickness direction here may refer to the thickness direction of the sealing door 1000, or the thickness direction of the movable door assembly 100 or the thickness direction of the door panel assembly 300, that is, the thickness direction of the sealing door 1000, the thickness direction of the movable door assembly 100 and the thickness direction of the door panel assembly 300 all refer to the same direction.

[0052] exist Figure 2 In the illustrated embodiment, the door opening H1 is a rectangular hole opened on the door panel assembly 300 . Of course, it may also be a circular hole, a square hole, etc. There is no specific limitation and it can be adjusted according to design requirements.

[0053] In a further optional embodiment, the opening and closing mechanism 200 includes a driving module 210 and a limiting module 220. The driving module 210 and the limiting module 220 are both connected to the door panel assembly 300, and the movable door assembly 100 is connected to the driving module 210.

[0054] The driving module 210 is used to drive the movable door assembly 100 to move, and the limiting module 220 is used to determine the closing position and the opening position.

[0055] In this embodiment, the driving module 210 and the limiting module 220 are both fixedly mounted on the door panel assembly 300 , and the movable door assembly 100 is connected to the driving module 210 , thereby realizing a movable connection with the door panel assembly 300 .

[0056] The driving module 210 can provide driving force for the movable door assembly 100 to move the movable door assembly 100, and the limiting module 220 is used to determine the stop position, i.e., the closed position and the open position, of the movable door assembly 100. The driving module 210 cooperates with the limiting module 220 to enable the movable door assembly 100 to move between the closed position and the open position.

[0057] It should be understood that the stop module 220 ensures that the stop position of the movable door assembly 100 is appropriate, specifically, when the movable door assembly 100 is in the open position, the movable door assembly 100 can fully open the door opening H1. When the movable door assembly 100 is in the closed position, the movable door assembly 100 fully closes the door opening H1, and sufficient sealing pressure is formed between the movable door assembly 100 and the door panel assembly 300.

[0058] It should be noted that the moving trajectory of the movable door assembly 100 driven by the driving module 210 can be a straight trajectory or an arc trajectory, etc., to ensure that the distance between the movable door assembly 100 and the door panel assembly 300 in the thickness direction changes gradually during the movement, and the specific design can be based on needs.

[0059] In a further optional embodiment, the driving module 210 is disposed on opposite sides of the door opening H1 and includes a rodless cylinder 211 and a support frame 212. The support frame 212 is connected to the door panel assembly 300, the rodless cylinder 211 is connected to the support frame 212, and the movable door assembly 100 is connected to the rodless cylinder 211 on both sides.

[0060] The limiting module 220 and the rodless cylinder 211 are located on opposite sides of the support frame 212. The limiting module 220 includes a first limiting module 221 and a second limiting module 222. The first limiting module 221 is used to determine the closed position, and the second limiting module 222 is used to determine the open position.

[0061] In this embodiment, the driving modules 210 are arranged on opposite sides of the door opening H1, and the driving modules 210 on one side are composed of a rodless cylinder 211 and a support frame 212. The rodless cylinder 211 is connected to the door panel assembly 300 through the support frame 212, and the movable door assembly 100 is fixedly mounted on the rodless cylinder 211 on both sides of the door opening H1.

[0062] The rodless cylinder 211 serves as a power device to provide a moving driving force for the movable door assembly 100 , and the support frame 212 serves to support the rodless cylinder 211 and the movable door assembly 100 .

[0063] In addition, the rodless cylinder 211 is fixedly installed on the side of the support frame 212 close to the door opening H1, and the first limiting module 221 and the second limiting module 222 are arranged at intervals along the moving direction of the movable door assembly 100 and are both located on the side of the support frame 212 away from the door opening H1.

[0064] The first limiting module 221 and the second limiting module 222 define the stop position of the movable door assembly 100 in the moving direction, which specifically corresponds to the closed position and the open position.

[0065] It should be understood that the rodless cylinders 211 on both sides can be driven synchronously, so that the movable door assembly 100 can maintain translational motion, thereby preventing the movable door assembly 100 from shaking during movement and ensuring stability during movement.

[0066] It should be noted that the number of the rodless cylinders 211 is preferably an even number, which can be 2, 4 or 6. When the number of the rodless cylinders 211 is not less than 4, the number of the rodless cylinders 211 in the single-side driving module 210 is not less than 2 and can be arranged side by side on the support frame 212 in the thickness direction.

[0067] In addition, the driving module 210 is not limited to being driven by the rodless cylinder 211 as a power source. For example, it can also be driven by a motor in conjunction with a guide rail slider, a ball screw and other transmission mechanisms, or it can also be driven by an oil cylinder, an electric push rod, etc., which can be adjusted according to needs.

[0068] exist Figure 1 and Figure 2 In the illustrated embodiment, the movable door assembly 100 and the door panel assembly 300 are both rectangular structures, and the number of the driving modules 210 is two. The two driving modules 210 are arranged at intervals along the length direction of the door panel assembly 300 and are respectively located on both sides of the length direction of the door opening H1. The number of the rodless cylinder 211 in the single-side driving module 210 is one.

[0069] The two ends of the movable door assembly 100 in the length direction are respectively connected to the rodless cylinders 211 in the driving modules 210 on both sides, and are driven by the rodless cylinders 211 on both sides to displace in the width direction and in the thickness direction.

[0070] In addition, the first limiting module 221 and the second limiting module 222 are arranged at intervals along the width direction of the door panel assembly 300 and are located at one side of the length direction of the door opening H1.

[0071] It should be noted that the arrangement of the driving module 210 and the limiting module 220 is not limited to the illustrated embodiment, as long as the sealing of the door opening H1 can be achieved. For example, the two driving modules 210 can also be arranged at intervals along the width direction of the door panel assembly 300 and are respectively located on both sides of the width direction of the door opening H1, and the two ends of the movable door assembly 100 in the width direction are respectively connected to the rodless cylinders 211 in the driving modules 210 on both sides, and are driven by the rodless cylinders 211 on both sides to displace in the length direction and also in the thickness direction.

[0072] In addition, the layout of the limiting module 220 is adjusted accordingly, and the first limiting module 221 and the second limiting module 222 are arranged at intervals along the length direction of the door panel assembly 300 and are located at one side of the width direction of the door opening H1.

[0073] In addition, Figure 1 and Figure 2 In the illustrated embodiment, the first limit module 221 and the second limit module 222 are arranged on one side of the door opening H1, that is, only one side of the driving module 210 is correspondingly arranged with the first limit module 221 and the second limit module 222, so as to determine the closed position and the open position.

[0074] Of course, the first limit module 221 and the second limit module 222 can be set on both sides of the door opening H1, that is, the driving modules 210 on both sides are correspondingly arranged with the first limit module 221 and the second limit module 222, and the first limit modules 221 on both sides are aligned to determine the closed position, and the second limit modules 222 on both sides are aligned to determine the open position.

[0075] Figure 3 for Figure 2 Sectional view at A in the figure. Figure 3 In a further optional embodiment, the rodless cylinder 211 includes a guide rod 2111 and a slider 2112 , the guide rod 2111 is connected to the support frame 212 , and the slider 2112 is slidably connected to the guide rod 2111 and can move along the guide rod 2111 .

[0076] The distances between the two ends of the guide rod 2111 and the door panel assembly 300 in the thickness direction are not equal. The movable door assembly 100 is connected to the slider 2112 and moves along the extension direction of the guide rod 2111 driven by the slider 2112 .

[0077] It can be understood that the biggest feature of the rodless cylinder 211 compared to the transmission cylinder is that it has no piston rod, which can significantly reduce the installation space and improve the compactness of the sealing door 1000 under the same stroke length.

[0078] In addition to the guide rod 2111 and the slider 2112, the rodless cylinder 211 also includes a cylinder body, a sealing system, an interface, etc. Since these components are not related to the content of this application, they are not described here.

[0079] The rodless cylinder 211 can realize linear motion. Specifically, the guide rod 2111 is fixedly mounted on the support frame 212 , and the slider 2112 can slide along the guide rod 2111 to realize linear motion. The extension direction of the guide rod 2111 is the moving direction of the slider 2112 .

[0080] In addition, the distance between the end of the guide rod 2111 close to the open position and the door panel assembly 300 in the thickness direction is greater than the distance between the end of the guide rod 2111 close to the closed position and the door panel assembly 300 in the thickness direction, that is, the guide rod 2111 is arranged inclined.

[0081] In this way, the movable door assembly 100 moves in a straight line driven by the slider 2112 and also generates displacement in the thickness direction. In other words, the rodless cylinder 211 is fixedly installed on the support frame 212 in an inclined manner to achieve driving the movable door assembly 100 to generate displacement in the thickness direction, and in the closed position, the movable door assembly 100 is closely attached to the door panel assembly 300 and completely covers the door opening H1, and in the open position, the movable door assembly 100 and the door panel assembly 300 are spaced apart in the thickness direction and the door opening H1 is completely opened.

[0082] It should be understood that the rodless cylinder 211 needs to be connected to an air circuit to realize its operation. When the movable door assembly 100 is in a closed position, the air circuit can be controlled to ensure that the rodless cylinder 211 maintains a certain air pressure so that the movable door assembly 100 can form a stable sealing pressure on the door panel assembly 300.

[0083] exist Figure 3 In the illustrated embodiment, the guide rod 2111 is arranged obliquely relative to the straight line in the width direction, and the distances between the two ends of the guide rod 2111 and the door panel assembly 300 in the thickness direction are unequal.

[0084] Figure 4 for Figure 2 In the B-direction view, the B-direction in the figure is the length direction. Figure 5 for Figure 1 See the enlarged view of point C in Figure 1. Figure 4 and Figure 5 In a further optional embodiment, the support frame 212 is provided with a guide hole H2, and the extension direction of the guide hole H2 is the extension direction of the guide rod 2111.

[0085] The first limiting module 221 and the second limiting module 222 are arranged at intervals along the extending direction of the guide hole H2. The slider 2112 is provided with a positioning structure 2113, which passes through the guide hole H2 and can move to the positions of the first limiting module 221 and the second limiting module 222.

[0086] In this embodiment, the moving direction of the slider 2112 is the extending direction of the guide rod 2111 , and the extending direction of the guide rod 2111 is the same as the extending direction of the guide hole H2 .

[0087] In this way, the first limit module 221 and the second limit module 222 are spaced apart along the moving direction of the slider 2112. Accordingly, the positioning structure 2113 fixedly mounted on the slider 2112 can move along the extension direction of the guide hole H2 and reach the positions of the first limit module 221 and the second limit module 222.

[0088] Furthermore, the open position and the closed position can be determined by the positioning structure 2113 cooperating with the first limiting module 221 and the second limiting module 222 respectively.

[0089] In some optional embodiments, the first limiting module 221 and the second limiting module 222 both include micro switches, and the positioning structure 2113 can abut against the micro switches to change the switch signal to determine that the movable door assembly 100 reaches the corresponding position.

[0090] In some other optional embodiments, the positioning structure 2113 is a baffle, and the first limiting module 221 and the second limiting module 222 both include slot-type photoelectric switches. The positioning structure 2113 can reach the groove of the slot-type photoelectric switch to change the switch signal, thereby determining that the movable door assembly 100 has reached the corresponding position.

[0091] In some optional embodiments, the support frame 212 includes a support plate 2121 and a support seat 2122, wherein the support seat 2122 is connected to the door panel assembly 300 and is located at both ends of the support plate 2121. The rodless cylinder 211 is disposed on the support plate 2121, and the guide hole H2 is disposed on the support plate 2121.

[0092] In this embodiment, the support frame 212 is composed of a support plate 2121 and two support seats 2122. The support plate 2121 is connected to the door panel assembly 300 through the support seats 2122 on both sides. The support plate 2121 is provided with a guide hole H2 extending along the movement direction of the slider 2112. After the rodless cylinder 211 is installed on the support plate 2121, the positioning structure 2113 can pass through the guide hole H2.

[0093] See also Figure 1 and Figure 2In some optional embodiments, the door panel assembly 300 includes a door panel body 310 and a limiting structure 320 , the limiting structure 320 is disposed on the door panel body 310 , and the door opening H1 is located in the door panel body 310 .

[0094] When the movable door assembly 100 is in the closed position or the open position, the movable door assembly 100 is connected to the limiting structure 320 .

[0095] In this embodiment, the driving module 210 , the limiting module 220 , and the limiting structure 320 in the opening and closing mechanism 200 are all fixedly mounted on the door panel body 310 , and the door opening H1 is opened in the door panel body 310 .

[0096] In addition to being limited by the limiting module 220 to determine the closed position and the open position, the movable door assembly 100 is further limited by the limiting structure 320. The limiting structure 320 can prevent the movable door assembly 100 from exceeding the closed position or the open position due to movement inertia, and determine the stability of the stop position of the movable door assembly 100.

[0097] In a further optional embodiment, the limiting structure 320 includes a first limiting seat array L1 and a second limiting seat array L2 , and the first limiting seat array L1 and the second limiting seat array L2 are located on both sides of the movable door assembly 100 in the moving direction of the movable door assembly 100 .

[0098] When the movable door assembly 100 is in the closed position, the movable door assembly 100 abuts against the first limiting seat array L1. When the movable door assembly 100 is in the open position, the movable door assembly 100 abuts against the second limiting seat array L2.

[0099] In this embodiment, the limiting structure 320 is composed of a first limiting seat array L1 and a second limiting seat array L2, and is arranged at intervals in the movement direction of the movable door assembly 100 and located on both sides of the movable door assembly 100. Therefore, the movable door assembly 100 can abut against the first limiting seat array L1 and the second limiting seat array L2 during movement.

[0100] Specifically, when the movable door assembly 100 reaches the closed position, the movable door assembly 100 is connected to the first position-limiting seat array L1. When the movable door assembly 100 reaches the open position, the movable door assembly 100 is connected to the second position-limiting seat array L2.

[0101] The first limiting seat L1 and the second limiting seat array L2 ensure that the movable door assembly 100 remains level at the stop position, thereby preventing the movable door assembly 100 from being uneven.

[0102] In a specific application, when the positioning structure 2113 reaches the position of the first limiting module 221, the movable door assembly 100 abuts against the first limiting seat array L1. When the positioning structure 2113 reaches the position of the second limiting module 222, the movable door assembly 100 abuts against the second limiting seat array L2.

[0103] In a further optional embodiment, both the first limiting seat array L1 and the second limiting seat array L2 include a plurality of limiting seats 321 that are spaced apart from each other.

[0104] In this embodiment, the single-side limit seat array includes a plurality of limit seats 321 installed at intervals on the door panel body 310. The plurality of limit seats 321 can form a plurality of contact positions with one side of the movable door assembly 100, thereby ensuring that the movable door assembly 100 remains horizontal.

[0105] In a specific application, the limiting seat 321 is provided with a buffer layer to reduce the impact of the movable door assembly 100 on the limiting seat 321 and also reduce noise. The buffer layer here can be a buffer rubber layer.

[0106] exist Figure 1 and Figure 2 In the illustrated embodiment, the first limiting seat array L1 and the second limiting seat array L2 are spaced apart along the thickness direction of the door panel assembly 300, and the limiting seat array on one side includes two limiting seats 321, which can respectively abut against both ends in the length direction of the movable door assembly 100. Of course, the number of limiting seats 321 in the limiting seat array on one side is not limited to the illustrated embodiment.

[0107] In some optional embodiments, the door panel assembly 300 further includes a plurality of hinged ends 340 , which are disposed on one side of the door panel body 310 and arranged at intervals.

[0108] As can be seen from the foregoing, the sealed door 1000 needs to be rotatably connected to the cabinet. In this embodiment, the hinged end 340 cooperates with the hinged structure (such as hinge, etc.) to realize the rotatable connection between the door panel assembly 300 and the cabinet, thereby realizing the rotatable connection between the entire sealed door 1000 and the cabinet, which is convenient for the staff to perform after-sales maintenance.

[0109] exist Figure 1 and Figure 2 In the illustrated embodiment, there are three hinge ends 340, all of which are disposed on one side of the length direction of the door panel body 310, and the three hinge ends 340 are spaced apart along the width direction of the door panel body 310. Of course, the number and arrangement of the hinge ends 340 are not limited to the illustrated embodiment.

[0110] Figure 6 for Figure 3 A partial enlarged view of D in the middle. Please refer to Figure 6In some optional embodiments, the door panel body 310 includes a front plywood layer 311, an intermediate heat-insulating layer 312, and a rear plywood layer 313. The front plywood layer 311, the intermediate heat-insulating layer 312, and the rear plywood layer 313 are stacked in sequence along the thickness direction.

[0111] In this embodiment, the door panel body 310 is a three-layer structure, wherein the middle insulation layer 312 can play a role in heat preservation. In specific applications, the middle insulation layer 312 is a rock wool layer, which has good heat preservation, heat insulation and fireproof performance. Of course, the middle insulation layer 312 can also be an insulation foam layer, etc., which can be adaptively adjusted according to needs.

[0112] It should be understood that the door panel body 310 is not limited to a three-layer panel structure, and the number of interlayers can be adaptively adjusted according to thermal insulation requirements.

[0113] In a further optional embodiment, the door panel assembly 300 further includes a sealing strip 330 , which is connected to the rear plywood layer 313 and disposed around the door panel body 310 .

[0114] From the above, it can be seen that the door panel assembly 300 needs to be rotatably connected to the cabinet body, wherein the rear plywood layer 313 is located on the side close to the cabinet body, and when the sealed door 1000 closes the cabinet body, the sealing strip 330 is clamped between the door panel assembly 300 and the cabinet body, and the thermal insulation performance is further improved by the sealing strip 330.

[0115] Figure 7 FIG. 1 is a partial cross-sectional view of a movable door assembly 100 provided according to one embodiment of the present application. Figure 7 The movable door assembly 100 includes a movable door body 110 and a sealing and heat-insulating layer 120. The sealing and heat-insulating layer 120 is attached to the movable door body 110 and is located between the movable door body 110 and the door panel assembly 300.

[0116] It should be understood that when the movable door assembly 100 is in a closed position, the movable door assembly 100 is in close contact with the door panel assembly 300, and the sealing and heat-insulating layer 120 is sandwiched between the movable door body 110 and the door panel assembly 300 to achieve a heat-insulating and sealing effect.

[0117] In a specific application, the sealing and heat-insulating layer 120 includes, for example, heat-insulating cotton, heat-insulating foam, etc. When the movable door assembly 100 is in a closed position, the sealing and heat-insulating layer 120 is squeezed and deformed, which is beneficial to heat-insulating sealing.

[0118] Figure 8 for Figure 2 A schematic diagram of the sealing door 1000 in another perspective. Figure 8The sealed door 1000 further includes a position detection module 400, which is disposed on a side of the door panel assembly 300 and away from the movable door assembly 100 in the thickness direction. The position detection module 400 is located at the peripheral side of the door opening H1.

[0119] It should be noted that after the sealed door 1000 is installed on the cabinet, the position detection module 400 is located inside the cabinet, the movable door assembly 100 is located outside the cabinet, and the battery is transported by a handling device and passes through the door opening H1 to be transported into the cabinet. It should be noted that the handling device here can be a stacker fork, a robotic arm, etc.

[0120] The position detection module 400 is mainly used to detect whether the handling equipment has passed through the door opening H1, so as to detect the loading and unloading process.

[0121] exist Figure 8 In the illustrated embodiment, the position detection module 400 is a photoelectric sensor including a transmitting end and a receiving end. The transmitting end is used to emit a light signal, and the receiving end is used to receive a light signal. One of the two is located in the middle of the width direction of the door opening H1, and the other is located at a corner of the door opening H1. In this way, the light signal is obliquely emitted relative to the straight line in the length direction, and the span of the light signal is larger, which is more conducive to sensing whether the handling equipment passes through the door opening H1.

[0122] It should be noted that the position detection module 400 is not limited to a photoelectric sensor, and may also be a laser sensor, for example.

[0123] In summary, the opening and closing mechanism 200 in the sealed door 1000 can drive the movable door assembly 100 to move relative to the door panel assembly 300, and determine the open position and the closed position of the movable door assembly 100. The opening and closing mechanism 200 causes the moving track of the movable door assembly 100 to be displaced in the thickness direction, and then the movable door assembly 100 is closely attached to the door panel assembly 300 in the closed position, so that the sealed door 1000 has good sealing performance when in the closed state, and accordingly, the thermal insulation performance of the cabinet can be improved.

[0124] Of course, the sealing door 1000 also has other advantages, which will not be repeated here. It should be understood that the battery testing equipment equipped with the sealing door 1000 obviously has all the beneficial effects brought by the sealing door 1000, which will not be repeated here.

[0125] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
