Figure 2E yes Figure 2B Side view of the lower center shell.

[0045] like Figure 2A and2B As shown, the housing 102 includes an upper housing 103 and a lower housing 104 . The upper housing 103 is connected to the lower housing 104 and encloses a hollow accommodation space 205 .

[0046] Figure 2C is the perspective of the upper housing 103 viewed from the inner side toward the lower housing 104, as shown in FIG. Figure 2C As shown, the upper shell 103 has an upper bottom 211, an upper side 212 and an edge 213. The upper bottom 211 is a substantially rectangular flat plate and has an opening 115. The opening 115 is a substantially rounded rectangle with arc chamfers. The upper side 212 extends from the edges of the upper bottom 211 along the height direction H1 of the cover assembly 100 (that is, a direction substantially perpendicular to the upper bottom 211), thereby enclosing an upper space 215 with the upper bottom 211. The edge 213 extends from one end of the upper side 212 away from the upper bottom 211 in a direction substantially parallel to the upper bottom 211, and the edge 213 is used to connect with the lower shell 104. The upper side 212 also has a pair of recesses 241 and 242, which are recessed from the distal end of the upper side 212 toward the upper bottom 211. In the length direction of the cover assembly 100, the recesses 241 and 242 are substantially aligned with the opening 115.

[0047] The upper bottom portion 211 , the upper side portion 212 and the edge 213 may have a certain curvature to adapt to the installation position of the vehicle, and the parallel and vertical mentioned here refer to the approximate directions.

[0048] Figure 2D is a perspective of the lower housing 104 from the top of the lower housing 104 downward, Figure 2E is a perspective viewed from the front side of the lower housing 104, as shown in FIG. Figure 2D and Figure 2EAs shown, the lower shell 104 has a lower bottom 221 and a lower side 222. The lower bottom 221 is a substantially rectangular flat plate and has an opening 225. The opening 225 is used to install the charging port of the vehicle. The opening 225 forms a charging area, and the charging area includes a first charging area 258 and a second charging area 259. The first charging area 258 and the second charging area 259 are distributed along the length direction L1 of the cover assembly 100. The lower side 222 extends from the edges of the lower bottom 221 along the height direction H1 of the cover assembly 100 (that is, a direction substantially perpendicular to the lower bottom 221), thereby enclosing a lower space 216 with the lower bottom 221. The upper shell 103 can cover the lower shell 104, and the edge 213 of the upper shell 103 can be connected to the lower side 222. The lower space 216 and the upper space 215 together form the accommodating space 205 of the shell 102. The lower side portion 222 has a front side portion 261 and a rear side portion 262 that are oppositely disposed, and the front side portion 261 and the rear side portion 262 extend along the length direction L1 of the cover assembly 100. The front side portion 261 and the rear side portion 262 have convex portions 263 and 264, respectively, and when the upper shell 103 and the lower shell 104 are connected, the convex portions 263 and 264 can enter the concave portions 241 and 242 of the upper shell 103.

[0049] The front side portion 261 and the rear side portion 262 are both provided with a limiting device, and the limiting devices on the front side portion 261 and the rear side portion 262 have the same structure. The limiting device on the front side portion 261 is used as an example to describe its structure. Figure 2D As shown, the limiting device includes a transverse guide groove 281 and a vertical guide groove 282. The transverse guide groove 281 extends along the length direction of the cover assembly and has a first end 295 and a second end 296. The vertical guide groove 282 extends along the height direction of the cover assembly and is connected to the transverse guide groove 281, so that the corresponding positioning component can slide between the vertical guide groove 282 and the transverse guide groove 281. In the length direction L1 of the cover assembly 100, the first end 295 and the second end 296 of the transverse guide groove 281 extend beyond the protrusion 263 of the front side portion 261. The vertical guide groove 282 includes a first groove 291 and a second groove 292, and there is a spacing between the first groove 291 and the second groove 292 in the length direction L1 of the cover assembly 100. The first groove 291 and the second groove 292 are respectively connected to the transverse guide groove 281 and extend in the direction of the upper housing 103 along the height direction H1 of the cover assembly. The first groove 291 and the second groove 292 are located on the protrusion 263 of the front side portion 261. In the length direction L1 of the cap assembly 100, the first groove 291 and the second groove 292 are spaced apart from the first end 295 and the second end 296 of the transverse guide groove 281.

[0050] Similarly, the rear side portion 262 includes a transverse guide groove 283 and a vertical guide groove 284 , which correspond to the shapes of the transverse guide groove 281 and the vertical guide groove 282 of the front side portion 261 , and are not described again herein.

[0051] Figure 3A yes Figure 1B A three-dimensional diagram of the middle cover. Figure 3B yes Figure 3A A three-dimensional view of the middle cover from another angle. Figure 3A is a view from the perspective of going up from the top of the cover 106, Figure 3B This is a view from below the cover 106 .

[0052] like Figure 3A and Figure 3B As shown, the cover 106 is generally a rounded rectangle and has a first side 311 and a second side 312. The first side 311 is a side facing the external space, and the second side 312 is a side facing the lower shell 104. The cover 106 has a cover body 301 and a flange 302. The shape of the cover body 301 matches the shape of the opening 115 of the upper shell 103, so that the cover body 301 can enter the opening 115. The flange 302 is formed by extending the edge of the cover body 301 to the surroundings, and the cover body 301 protrudes from the flange 302. When the cover body 301 enters the opening 115 of the upper shell 103, the flange 302 abuts against the surroundings of the opening 115 of the upper shell 103 to prevent the cover 106 from passing through the opening 115. The second side 312 of the cover 106 has a pair of shaft mounting parts 381 and 382 for connecting with the rotating assembly 107.

[0053] Figure 4 yes Figure 1B A perspective view of the rotating assembly, such as Figure 4As shown, the rotating assembly 107 includes a first rotating transmission member 401 and a second rotating transmission member 402, and the first rotating transmission member 401 and the second rotating transmission member 402 have the same structure and are respectively connected to the shaft mounting portion 381 and 382 of the cover 106. The structure of the rotating transmission member will be described below by taking the second rotating transmission member 402 as an example. The second rotating transmission member 402 includes a first shaft 411, a second shaft 412, and a connecting portion 413. The connecting portion 413 includes a front portion 415 and a rear portion 416. The front portion 415 and the rear portion 416 are provided with through holes to allow the first shaft 411 and the second shaft 412 to pass through. The first shaft 411 and the second shaft 412 are connected through the connecting portion 413, and the first shaft 411 and the second shaft 412 are arranged in parallel, and there is a spacing between the first shaft 411 and the second shaft 412. The first shaft 411 and the second shaft 412 pass through and extend out of the front portion 415 and the rear portion 416. The first shaft 411 and the second shaft 412 together form a positioning portion 420. The front portion 415 has a convex portion 440, which is substantially flush with the first shaft 411 and has a spacing with the second shaft 412, and is used to install the torsion spring 150. The size of the first shaft 411 matches the size of the first slot 291 or the second slot 292 of the lower housing 104, so that the first shaft 411 can move in the first slot 291 or the second slot 292 along the height direction H1 of the cover assembly 100, but cannot shake along the length direction L1.

[0054] Figure 5 yes Figure 1B The three-dimensional diagram of the torsion spring is as follows: Figure 5 As shown, the torsion spring 150 has a main body 501, and a first arm 511 and a second arm 512 extending from the main body 501. There is an angle between the first arm 511 and the second arm 512. The first arm 511 and the second arm 512 can move closer to or farther from each other, thereby generating elastic force.

[0055] Figure 6 yes Figure 1B A three-dimensional diagram of the seal. Figure 6 As shown, the seal 120 is generally a rectangular plate and has a first side 601 facing the upper shell 103 and a second side 602 facing the lower shell 104. The first side 601 of the seal 120 has mounting portions 611 and 612, and the mounting portions 611 and 612 have mounting channels 623 and 624. The second shaft 412 of each of the first rotating transmission member 401 and the second rotating transmission member 402 can pass through the mounting channel 623 or 624 to connect the rotating assembly 107 with the seal 120. The second side 602 forms a sealing surface that can contact the charging port. The seal 120 is made of a material with a certain elasticity and can undergo a certain deformation.

[0056] Figure 7 yes Figure 1BSchematic diagram of the connection between the middle cover, transmission assembly, torsion spring and seal. Figure 7 As shown, the first shaft 411 of the first rotating transmission member 401 and the second rotating transmission member 402 passes through and extends out of the shaft mounting parts 381 and 382 of the cover 106. The first shaft 411 can rotate relative to the shaft mounting parts 381 and 382, ​​so that the cover 106 is connected to the rotating transmission members 401 and 402 through the first shaft 411. The second shaft 412 of the first rotating transmission member 401 and the second rotating transmission member 402 passes through and extends out of the mounting parts 611 and 612 of the sealing member 120, so that the sealing member 120 is connected to the rotating transmission members 401 and 402 through the second shaft 412. The first arm 511 of the torsion spring 150 is connected to the protrusion 440 of the second rotating transmission member 402, and the other end is connected to the sealing member 120. The first arm 511 of the torsion spring 150 is roughly flush with the first shaft 411 of the second rotating transmission member 402, and the second arm 512 is roughly flush with the second shaft 412 of the second rotating transmission member 402. The torsion spring 150 provides an elastic force between the first shaft 411 and the second shaft 412 of the second rotating transmission member 402. The torsion spring 150 keeps the first shaft 411 of the second rotating transmission member 402 relative to the second shaft 412 of the second rotating transmission member 402 at a position such as Figure 7 In the vertical position shown, that is, along the height direction H1 of the cover assembly 102 , the first shaft 411 of the second rotation transmission member 402 is located directly above the second shaft 412 of the second rotation transmission member 402 .

[0057] Figure 8 yes Figure 1A The cover assembly in the figure hides the motor and the front housing baffle. Figure 8 The figure shows the matching relationship between the linear transmission parts, gears and rotating components. Figure 8 As shown, the first shaft 411 and the second shaft 412 of the rotating assembly 107 are located in the transverse guide groove 281 and the vertical guide groove 282 of the housing 102. That is, the positioning portion 420 is located in the limiting device. Figure 8In the state shown, the cover 106 is in the closed position, the cover 106 covers the opening 115, and the main body 301 of the cover 106 is approximately flush with the outer surface of the upper shell 103. The first shaft 411 is located at the top of the vertical guide groove 282, and the second shaft 412 is approximately located directly below the first shaft 411. The linear transmission member 108 is a rack, one side of which has teeth 811, and the teeth 811 are distributed along the length direction of the cover assembly 100, and the teeth 811 can be engaged with the gear 132. The second shaft 412 is connected to the linear transmission member 108, and the linear transmission member 108 can drive the second shaft 412 to move. When the gear 132 rotates, the linear transmission member 108 moves linearly along the length direction L1 through the cooperation of the teeth 811 and the gear 132. The gear 132 is driven by the motor 131 and can rotate forward or reverse, thereby driving the linear transmission member 108 to move along the first direction D1 or the second direction D2 as shown by the arrow.

Figure 9A-9E The movement of the cover is shown for easy understanding. Figure 9A-9E The view in Figure 2 hides the motor, the housing cover on the front, the linear drive and the gears.

[0059] like Fig. 9A As shown, when the cover is in the closed position, the cover 106 is located at the highest position in the height direction of the cover assembly 100, the cover 106 covers the opening 115, and the main body 301 of the cover 106 is roughly flush with the outer surface of the upper shell 103. The first axis 411 is located at the top of the vertical guide groove 282, and the second axis 412 is located in the horizontal guide groove 281 and is directly below the first axis 411. That is, in the closed position of the cover, the first axis 411 is distributed along the height direction of the cover assembly 100 relative to the second axis 412. The torsion spring 150 is not compressed at this time and can keep the rotating assembly 107 in this position. At this time, if the operator presses the cover 106, the force direction of the operator is in a straight line with the first axis 411 and the second axis 412, and the first rotating transmission member 401 and the second rotating transmission member 402 will not deflect, so that the cover 106 is locked and does not move along the height direction H1.

[0060] When the cover 106 is about to move from the closed position to the first open position, it first reaches the intermediate position. Fig. 9B As shown, the motor 131 drives the gear 132 to rotate forward, so that the linear transmission member 108 moves along the first direction D1. The linear transmission member 108 drives the second shaft 412 of the rotating transmission members 401 and 402 to move along the first direction D1 in the transverse guide groove 281, so that the first shaft 411 of the rotating transmission members 401 and 402 moves toward the transverse guide groove 281 along the height direction H1, and the rotating transmission members 401 and 402 rotate, so that the torsion spring 150 is deformed and elastic restoring force is stored. When the first shaft 411 enters the transverse guide groove 281 and is flush with the second shaft 412, the cover 106 reaches the middle position. At this time, the cover 106 leaves the opening 115 of the upper shell 103 and reaches the lowest position downward. In the process of moving from the closed position to the middle position, the cover 106 moves downward (i.e., toward the lower shell 104) along the height direction H1 of the cover assembly 100.

[0061] When the cover 106 moves from the middle position to the first open position, the motor 131 drives the gear 132 to continue to rotate forward, and the linear transmission member 108 continues to move along the first direction D1. The linear transmission member 108 drives the second shafts 412 of the rotating transmission members 401 and 402 to continue to move in the first direction D1 in the transverse guide groove 281. During this movement, the first shafts 411 of the rotating transmission members 401 and 402 move in the transverse guide groove 281 along the first direction D1 along with the second shaft 412. During the above movement, the first shaft 411 and the second shaft 412 are both located in the transverse guide groove 281, that is, the first shaft 411 and the second shaft 412 are arranged along the length direction L1 of the cover assembly 100. Fig. 9C As shown, when the second shaft 412 moves to a specific position, the cover 106 reaches a first open position. In the first open position, the left side of the opening 115 is exposed. A portion of the cover 106 corresponds to the right side of the opening 115.

[0062] When the cover 106 moves from the first open position to the closed position, the motor 131 drives the gear 132 to rotate in the opposite direction, so that the linear transmission member 108 drives the second shaft 412 of the rotary transmission members 401 and 402 to move in the transverse guide groove 281 along the second direction D2. Fig. 9B When the cover 106 is in the middle position shown in FIG. 1 , the first shaft 411 enters the vertical guide groove 281. The second shaft 412 is continuously moved along the second direction D2 until it is aligned with the first shaft 411. Fig. 9A Shown in closed position.

[0063] In one embodiment of the present application, in the first open position, the second shaft 412 of the rotating transmission member 402 reaches the second end 296 of the transverse guide slot 281, and the second shaft 412 of the rotating transmission member 402 cannot continue to move along the first direction. In another embodiment of the present application, in the first open position, the second shaft 412 of the rotating transmission member 402 is at a certain distance from the second end 296 of the transverse guide slot 281, and the second shaft 412 of the rotating transmission member 402 can continue to move along the first direction.

[0064] When the cover 106 is about to move from the closed position to the second open position, it also reaches the intermediate position first. Fig.9D As shown, the motor 131 drives the gear 132 to rotate in the opposite direction, so that the linear transmission member 108 moves along the second direction D2. The linear transmission member 108 overcomes the elastic force of the torsion spring 150 and drives the second shaft 412 of the rotating transmission members 401 and 402 to move in the second direction D2 in the transverse guide groove 281, so that the first shaft 411 of the rotating transmission members 401 and 402 moves toward the transverse guide groove 281 along the height direction H1, and the rotating transmission members 401 and 402 rotate, so that the torsion spring 150 is deformed and the elastic restoring force is accumulated. When the first shaft 411 enters the transverse guide groove 281 and is flush with the second shaft 412, the cover 106 reaches the middle position. Fig. 9B The state shown is the same, at this time, the cover 106 leaves the opening 115 of the upper shell 103 and reaches the lowest position downward. For the cover 106, no matter it moves toward the first open position or the second open position, the middle position of the cover 106 is the position when it moves downward (i.e., toward the lower shell 104) along the height direction H1 of the cover assembly 100 to reach the lowest position. For the rotating transmission members 401 and 402, when the cover 106 reaches the middle position, the positions of the second shafts 412 of the rotating transmission members 401 and 402 are different. In the length direction of the cover assembly 100, during the movement of the rotating transmission members 401 and 402, the respective second shafts 412 are always located upstream in the movement direction of the corresponding first shaft 411.

[0065] When the cover 106 moves from the middle position to the second open position, the motor 131 drives the gear 132 to continue to rotate in the opposite direction, and the linear transmission member 108 continues to move along the second direction D2. The linear transmission member 108 drives the second shafts 412 of the rotating transmission members 401 and 402 to continue to move in the second direction D2 in the transverse guide groove 281. During this movement, the first shaft 411 of the rotating transmission members 401 and 402 moves in the transverse guide groove 281 along the second direction D2 along with the second shaft 412. During the above movement, the first shaft 411 and the second shaft 412 are both located in the transverse guide groove 281, that is, the first shaft 411 and the second shaft 412 are arranged along the length direction L1 of the cover assembly 100. Fig.9EAs shown, when the second shaft 412 moves to a specific position, the cover 106 reaches a second open position. In the second open position, the right side of the opening 115 is exposed. A portion of the cover 106 corresponds to the left side of the opening 115.

[0066] When the cover 106 moves from the second open position to the closed position, the motor 131 drives the gear 132 to rotate in the positive direction, so that the linear transmission member 108 drives the second shaft 412 of the rotary transmission members 401 and 402 to move in the transverse guide groove 281 along the first direction D1. Fig.9D When the cover 106 is in the middle position shown in FIG. 1 , the first shaft 411 enters the vertical guide groove 281. The second shaft 412 is continuously moved along the first direction D1 until it is aligned with the first shaft 411. Fig. 9A Shown in closed position.

[0067] and Fig. 9C Similar to the first open position of the cover shown, in one embodiment of the present application, in the second open position, the second shaft 412 of the rotating transmission member 402 reaches the first end 295 of the transverse guide slot 281, and the second shaft 412 of the rotating transmission member 401 cannot continue to move along the first direction. In another embodiment of the present application, in the second open position, the second shaft 412 of the rotating transmission member 401 is at a certain distance from the first end of the transverse guide slot 281, and the second shaft 412 of the rotating transmission member 401 can continue to move along the second direction.

[0068] In the present application, the cover 106 has a closed position, an intermediate position, a first open position, and a second open position. In the closed position, the cover 106 is in a locked state, and the thrust applied by the operator cannot move the cover 106. The cover 106 can move in two directions relative to the housing 102 to reach the first open position and the second open position.

[0069] Fig.10 yes Fig.9E Schematic diagram of the state of the cover, the rotating assembly and the torsion spring when the middle cover is in the second open position. Fig.10 As shown in FIG. 1 , when the cover is in the second open position, the angle between the first arm 511 and the second arm 512 of the torsion spring 150 increases, so that the torsion spring 150 is in a compressed state. The first arm 511 of the torsion spring 150 applies elastic force to the first shaft 411 of the rotating transmission member 402, so that the first shaft 411 tends to move upward relative to the second shaft 412. Fig.9E In the process of returning from the second open position to the closed position, when the first shaft 411 reaches the position of the second groove 292, the cover 106 reaches the position as shown in FIG. Fig.9DUnder the action of the torsion spring 150, the first shaft 411 will enter the second slot 292 instead of crossing the second slot 292 and continuing to move along the horizontal guide slot 281. After the first shaft 411 enters the second slot 292, the second shaft 412 continues to move to align with the first shaft 411, and the cover 106 returns to the closed position.

[0070] Similarly, in the case where the cover is located Fig. 9C In the first open position shown in FIG. 1 , the torsion spring 150 is also in a compressed state and applies elastic force to the first shaft 411 of the rotating transmission member 402, so that the first shaft 411 tends to move upward relative to the second shaft. Fig. 9C In the process of returning from the first open position to the closed position, when the first shaft 411 reaches the position of the second groove 292, the cover 106 reaches the position shown in FIG. Fig. 9B Under the action of the torsion spring 150, the first shaft 411 will enter the second slot 292 instead of crossing the second slot 292 and continuing to move along the horizontal guide slot 281. After the first shaft 411 enters the second slot 292, the second shaft 412 continues to move to align with the first shaft 411, and the cover 106 returns to the closed position.

[0071] In this embodiment, the torsion spring 150 guides the first shaft 411 of the rotary transmission member to enter the vertical guide groove 281 when the cover 106 returns to the closed position.

The operator can perform charging operation on the first charging port 1101 through the opening 115 of the upper shell 103. At the same time, since the second charging port 1102 is covered by the cover 106, the cover 106 can prevent external dust or water from entering the second charging port 1102.

[0075] like Fig. 11B As shown, when the cover 106 is in the second open position, the first charging area 258 and the first charging port 1101 are covered by the cover 106, and the second charging port 1102 is exposed. The operator can perform charging operation on the second charging port 1102 through the opening 115 of the upper shell 103. At the same time, since the first charging port 1101 is covered by the cover 106, the cover 106 can prevent external dust or water from entering the first charging port 1101.

[0076] Fig.12 yes Figure 1A A cross-sectional view of the cover assembly and the charging port component in FIG. Fig.12 The figure shows the matching relationship between the sealing member 120 and the charging port element 1110. Fig.12 As shown, the seal 120 is connected to the cover 106 through the rotating assembly 107. The seal 120 can follow the cover 106 to move along the length direction L1 of the cover assembly. The installation part of the cover assembly has a charging port element 110. When the cover 106 is in the closed position, the sealing surface of the seal 120 covers the surface of the charging port element 110 to prevent foreign matter from entering the first charging port or the second charging port.

[0077] When the cover 106 is located at the first open position or the second open position, the seal 120 covers the charging port covered by the cover 106 to prevent foreign matter from entering the corresponding charging port.

[0078] In one application of the present application, the cover assembly is suitable for a vehicle having two charging ports, a high-voltage port and a low-voltage port. Only one charging port needs to be used when charging the vehicle. If the other charging port is exposed to the external environment, dust, water or other impurities are easily introduced. The cover assembly in the present application has two opening positions, which can open one of the charging ports and cover the other charging port. The operator can use the opening position of the cover as needed. The cover assembly in the present application can prevent impurities from entering the other unused charging port during the charging process of the vehicle.
