Description

Technical Field

[0001] The present application relates to a cover and a cover assembly, and in particular to a cover and a cover assembly suitable for charging ports of different diameters on new energy vehicles. Background Art

[0002] New energy vehicles need to be equipped with charging seats, which usually have DC charging ports and AC charging ports. In order to save costs, more and more car companies are using charging seats with integrated DC charging ports and AC charging ports. When new energy vehicles are charged outdoors, first open the charging seat cover on the surface of the vehicle body to expose the charging port. When charging, the charging gun can only seal the charging port being charged, while the other charging port will be exposed to the external environment. If it rains while the new energy vehicle is charging, the charging port exposed to the external environment will be at risk of water ingress, which may affect the performance of the charging connection device and bring safety hazards. Since the sizes of DC and AC charging ports in China are different, the above problems can be solved by setting two charging port covers to seal the DC charging port and the AC charging port respectively. The corresponding charging port cover needs to be removed during charging. Summary of the invention

[0003] Considering that using two charging port covers to seal the DC charging port and the AC charging port respectively will increase the complexity of the charging operation, for example, each time a charging operation is performed, it is necessary to first open the charging seat cover on the surface of the vehicle body, and then open the corresponding charging port cover (DC charging port cover or AC charging port cover), a dual-purpose charging port cover can be designed. When the charging gun is aimed at one of the charging ports for charging, the charging port cover can seal the other unused charging port. Since the dual-purpose charging port cover is provided with a sealing portion with a corresponding outer diameter on both sides of the cover, it can be applied to charging ports of two different diameters, such as an AC charging port or a DC charging port.

[0004] However, the two sealing parts of the dual-purpose charging port cover are respectively arranged on both sides of the cover, so when the charging port cover seals one of the charging ports (e.g., the DC charging port), the sealing part used to seal the other charging port (e.g., the AC charging port) will be exposed to the outside, so that during the charging operation, the other sealing part (e.g., the sealing part sealing the AC charging port) faces a greater possibility of being contaminated by the external environment (dust, rain, etc.). If the contaminated sealing part (e.g., the sealing part sealing the AC charging port) is used to seal the other charging port (e.g., the AC charging port), the charging port (e.g., the AC charging port) will be contaminated, and then the electrical components (e.g., the socket, etc.) inside the charging port will be contaminated.

[0005] In addition, the charging port cover of the prior art requires manual operation to remove or seal the charging port, so that the contaminants on the user's hands will also contaminate the sealing part of the charging port during the above operation, and further contaminate the electrical components inside the charging port. At the same time, manually touching the charging port cover also poses a risk of electric shock.

[0006] Based on the technical problems existing in the above prior art, the present application provides a charging port cover, which can be used to seal two charging ports of different diameters. The two sealing parts of the charging port cover are arranged on the same side of the cover. When in use, the two sealing parts are simultaneously facing the inner side of the charging port, and no sealing part is exposed to the outer side of the charging port, thereby reducing the possibility of the sealing part being contaminated. The charging port cover of the present application is movably connected to the charging seat through a four-bar linkage mechanism. In the process of switching the charging port cover from one charging port to another, one side of the sealing part of the charging port cover always remains facing the inner side of the charging port, thereby reducing the possibility of the sealing part being contaminated during the use of the charging port cover when switching the charging port. At the same time, the present application uses a motor to drive the movement of the charging port cover through a four-bar linkage mechanism, avoiding manual direct operation of the charging port cover to switch the sealed charging port, which not only avoids the possibility of electric shock to the human body, but also further increases the controllability of the charging port cover to switch the charging port, which can meet the needs of integrated control of future new energy vehicles.

Where possible, the same or similar reference numerals used in this application refer to the same components.

[0044] Figures 1A-1C 1 is a three-dimensional diagram of the charging assembly 100 of the present application. Figure 1A It shows the charging gun 101 is about to be used with the DC interface 132. Figure 1B It shows the charging gun 101 is about to be used with the AC interface 134. Figure 1C It is an exploded view of the charging component 100 to illustrate the matching relationship between the various components in the charging component 100.

[0045] like Figure 1C As shown, the charging assembly 100 of the present application includes a cover assembly, a DC interface 132 and an AC interface 134, and the cover assembly is arranged on the inner side of the body 102 of the new energy vehicle. Specifically, a charging seat opening 103 is opened on the body 102, and the cover assembly is arranged on the inner side of the body corresponding to the corresponding position of the charging seat opening 103, and a charging seat cover 104 is arranged near the charging seat opening 103 to close the charging seat opening 103. Figures 1A-1C 2 is a schematic diagram showing that the charging seat cover 104 is in an open state. When the charging seat cover 104 is closed, the charging seat cover 104 can remain flush with the surface of the vehicle body 102.

[0046] In the embodiment of the present application, the opening and closing of the charging seat cover 104 can be controlled by the main control system of the car (not shown in the figure). For ordinary technicians in this field, in some other embodiments, the opening and closing of the charging opening cover 104 can also be operated manually.

[0047] like Figures 1A-1C As shown, the cover assembly includes a cover 106, a charging seat 111, an upper connecting rod 112 and a lower connecting rod 114, wherein the upper connecting rod 112 and the lower connecting rod 114 have the same length, and are used to movably connect the cover 106 to the charging seat 111. Two charging ports are respectively provided through the inner end surface of the charging seat 111. In an embodiment of the present application, the cross-section of the charging port is roughly circular, and the above-mentioned two charging ports are charging ports with different apertures, namely, a DC charging port 122 and an AC charging port 124, wherein the DC charging port 122 includes a DC charging port inner wall 142 with a first diameter, and the AC charging port 124 includes an AC charging port inner wall 144 with a second diameter, and the cover 106 can respectively produce an interference fit with the DC charging port inner wall 142 and the AC charging port inner wall 144 to seal the DC charging port 122 and the AC charging port 124. In the embodiment of the present application, the aperture of the DC charging port inner wall 142 of the DC charging port 122 is larger than the aperture of the AC charging port inner wall 144 of the AC charging port 124. In some other embodiments, the aperture of the DC charging port inner wall 142 may also be set to be smaller than the aperture of the AC charging port inner wall 144.

[0048] For those skilled in the art, in some other embodiments, the DC charging port 122 and the AC charging port 124 may also be configured to have the same aperture.

[0049] For those skilled in the art, in some other embodiments, the cross-sections of the DC charging port 122 and the AC charging port 124 may also be set to other shapes, such as an ellipse or a rectangle with rounded corners.

[0050] For those skilled in the art, in some other embodiments, the cross-sections of the DC charging port 122 and the AC charging port 124 may also be configured to be different shapes from each other.

[0051] like Figure 1A-1BAs shown, the DC interface 132 can be extended into the DC charging port 122 and partially accommodated inside the DC charging port 122. Similarly, the AC interface 134 can be extended into the AC charging port 124 and partially accommodated inside the AC charging port 124, so that the charging gun 101 can pass through the charging seat opening 103 and the DC charging port 122 from the outside of the vehicle body 102 in sequence to engage with the DC interface 132 and maintain electrical connection, or pass through the charging seat opening 103 and the AC charging port 124 in sequence to engage with the AC interface 134 and maintain electrical connection. A charging gun fixing portion 108 is also provided above the DC charging port 122 and the AC charging port 124 of the charging seat 111, respectively, for fixing the charging gun 101 when the charging gun 101 is engaged with the DC interface 132 or the AC interface 134, thereby preventing the charging gun 101 from accidentally falling off when the vehicle is charging.

[0052] Continue to refer to Figures 1A-1C The inner end surface of the charging seat 111 is also provided with an upper pivot connection portion 136 and a lower pivot connection portion 138. The upper pivot connection portion 136 is pivotally connected to one end of the upper connecting rod 112, and the lower pivot connection portion 138 is pivotally connected to one end of the lower connecting rod 114. The other ends of the upper connecting rod 112 and the lower connecting rod 114 relative to the charging seat 111 are respectively connected to the cover pivot upper portion 222 of the cover 106 (see Figure 2A ) and the cover pivot lower portion 224 (see Figure 2A ) are pivotally connected together. The end of the upper link 112 connected to the upper pivot connection 136 can swing back and forth around the pivot axis D, the end of the lower link 114 connected to the lower pivot connection 138 can swing back and forth around the pivot axis C, the end of the upper link 112 connected to the upper cover pivot portion 222 can swing back and forth around the pivot axis B, and the end of the lower link 114 connected to the lower cover pivot portion 224 can swing back and forth around the pivot axis A. The pivot axis B and the pivot axis A pass through the upper cover pivot portion 222 and the lower cover pivot portion 224 of the cover 106, respectively, and the pivot axis D and the pivot axis C pass through the upper pivot connection portion 136 and the lower pivot connection portion 138 of the charging base 111, respectively. The pivot axis A, the pivot axis B, the pivot axis C and the pivot axis D are parallel to each other and are arranged at a distance from each other, so that the cover 106, the charging base 111, the upper connecting rod 112 and the lower connecting rod 114 form a four-bar linkage (see Figures 3A-3C description).

[0053] Figures 2A-2C The specific structure of the cover 106 is shown from multiple perspectives, wherein Figure 2A 1 shows a perspective view of the cover 106 viewed from the outside of the charging port, Figure 2B 1 shows a perspective view of the cover 106 viewed from the inside of the charging port. Figure 2C For cover 106 along Figure 2B Sectional view taken along section line MM.

[0054] like Figure 2A-2B As shown, the cover 106 has a cover body 201, which is in the shape of a disc as a whole and is made by integral casting. The manufacturing material of the cover 106 is a soft plastic, such as TPE, so that the cover 106 can produce an interference fit with the inner wall of the charging port through elastic deformation when it is matched with the charging port, thereby sealing the charging port. When the cover 106 is inserted into the charging port, it can be sealed and fixed with the charging port through interference fit with the charging port; when the cover 106 is subjected to a pulling force toward the outside of the charging port, the interference fit part of the cover 106 can be separated from the sealing fixation with the charging port through elastic deformation.

[0055] For the convenience of description, the side of the cover 106 viewed from the outside of the charging port is defined as the outside of the cover, and the side of the cover 106 viewed from the inside of the charging port is defined as the inside of the cover. The outside and inside of the cover 106 are two sides of the cover 106 facing opposite to each other.

[0056] like Figure 2A As shown, a cover handle 202 is provided on the outward side of the cover body 201, which includes two handle recesses 211 and 212 recessed toward the inner side of the cover body 201, for facilitating the user's fingers to hold the cover 106. A cover pivot upper portion 222 and a cover pivot lower portion 224 are provided on the upper and lower sides of the cover handle 202, respectively, wherein the cover pivot upper portion 222 is pivotally connected to the upper connecting rod 112 and can pivot around the pivot axis B; the cover pivot lower portion 224 is pivotally connected to the lower connecting rod 114 and can pivot around the pivot axis A. The pivot axis A and the pivot axis B are parallel to each other and are staggered by a certain distance from each other along the transverse direction of the cover 106 in the figure.

[0057] like Figure 2B-2C As shown, the cover body 201 has a DC seal 204 and an AC seal 206 formed in sequence from outside to inside along the axial direction on the other side (the side facing inward) of the cover handle 202. In the embodiment of the present application, the cross-section of the outer periphery of the DC seal 204 and the AC seal 206 is substantially circular. Figure 2C As shown, from the radial direction of the cover body 201, the DC sealing part 204 and the AC sealing part 206 are arranged in a stepped shape, and are located in the outer circumferential direction of the cover body 201. The outer circumferential diameter of the DC sealing part 204 is larger than the outer circumferential diameter of the AC sealing part 206. The DC sealing part 204 is used to seal the DC charging port 122, and its diameter is slightly larger than the inner aperture of the DC charging port 122, so that it can form an interference fit with the inner wall 142 of the DC charging port, and can be temporarily fixed on the DC charging port 122. The AC sealing part 206 is used to seal the AC charging port 124, and its diameter is slightly larger than the inner aperture of the AC charging port 124, so that it can form an interference fit with the inner wall 144 of the AC charging port, and can be temporarily fixed on the AC charging port 124.

[0058] For those skilled in the art, in some other embodiments, since the apertures of the DC charging port 122 and the AC charging port 124 are also set to be the same, the outer diameter of the DC sealing portion 204 can also be set to be the same as the outer diameter of the AC sealing portion 206 .

[0059] For ordinary technicians in this field, in some other embodiments, since the cross-sections of the DC charging port 122 and the AC charging port 124 can be set to other shapes, such as an ellipse or a rectangle with rounded corners, the outer contours of the DC sealing portion 204 and the AC sealing portion 206 can also be set to a shape that matches the cross-sections of the DC charging port 122 and the AC charging port 124.

[0060] For ordinary technicians in this field, in some other embodiments, since the cross-sections of the DC charging port 122 and the AC charging port 124 can be set to different shapes, the outer peripheral contours of the DC sealing portion 204 and the AC sealing portion 206 can also be set to different shapes to match the cross-sectional shapes of the DC charging port 122 and the AC charging port 124.

[0061] Continue to refer to Figure 2B-2C The inner end surface of the cover 106 has an inner side wall 210, and a portion of the material of the inner side wall 210 protrudes outward to form a stop structure 208, which can abut against the end of the DC interface 132 or the AC interface 134, and is used to position or stop the cover 106 in the axial direction when the cover 106 seals the DC charging port 122 or the AC charging port 124 (see Figure 4B and 5B ).

[0062] Figures 3A-3C A schematic diagram showing the connection of the cover 106 through a four-bar linkage during the process of switching the charging port. Figure 3A A perspective view showing the cover 106 in an intermediate position during the process of switching the charging port, Figure 3B for Figure 3A The top view T of the charging assembly 100 in this state is shown. Figure 3C for Figure 3B A simplified diagram of the four-bar linkage in the charging assembly 100 is shown.

[0063] like Figure 3A-3B As shown, when the cover 106 switches from the sealed DC charging port 122 to the AC charging port 124 or from the sealed AC charging port 124 to the DC charging port 122, the cover 106 will be translated outward relative to the charging seat 111 as a whole (as shown in FIG. Figure 3BIn the above switching process, since the cover 106, the charging seat 111, the upper connecting rod 112 and the lower connecting rod 114 form a four-bar linkage, the cover 106 will not flip during the translation process, that is, the DC sealing part 204 and the AC sealing part 206 of the cover 106 are always facing the direction of the DC charging port 122 or the AC charging port 124 (the inner side of the vehicle body 102). In order to further explain the working principle of the switch movement of the cover 106, Figure 3C The structures of the cover 106, the upper connecting rod 112 and the lower connecting rod 114 of the charging base 111 are simplified into lines.

[0064] exist Figure 3C In the figure, the cover 106 is simplified as a line segment AB, the charging seat 111 is simplified as a line segment CD, the upper connecting rod 112 is simplified as a line segment BD, and the lower connecting rod 114 is simplified as a line segment AC. Since the length of the upper connecting rod 112 is equal to the length of the lower connecting rod 114, the length of the line segment BD is equal to the length of the line segment AC. Accordingly, by setting a reasonable distance, the distance between the pivot axis A passing through the cover 106 and the pivot axis B can be set to be equal to the distance between the pivot axis C passing through the charging seat 111 and the pivot axis D, so the length of the line segment AB is equal to the length of the line segment CD. Therefore, the line segments AB, CD, AC, and BD can form a parallelogram, and the line segments AC and BD can swing synchronously relative to the line segments AB and CD. During the swinging process of the line segments AC and BD, the line segments AB and CD always remain parallel to each other. Specifically in the cover assembly of the present application, the cover 106 can swing relative to the charging base 111 through the connection between the upper connecting rod 112 and the lower connecting rod 114. During this process, the cover 106 only moves in a translational manner but does not rotate (flip).

[0065] In an embodiment of the present application, the cover assembly further includes an actuator (not shown in the figure). The actuator is disposed on the inner side of the charging seat 111 facing the interface, and is used to drive the upper connecting rod 112 or the lower connecting rod 114 to pivot, or to drive the upper connecting rod 112 and the lower connecting rod 114 to pivot at the same time. The actuator is electrically connected to the main control system of the vehicle (not shown in the figure) in a communicative manner, and the actuator can be controlled by the main control system of the vehicle to drive the upper connecting rod 112 or the lower connecting rod 114 to pivot, thereby controlling the cover 106 to switch back and forth between the sealed DC charging port 122 and the AC charging port 124.

[0066] In an embodiment of the present application, corresponding position sensors (not shown in the figure) are also provided on the DC charging port 122 and the AC charging port 124, which can detect whether the cover 106 is in a position to seal the DC charging port 122 or the AC charging port 124, and transmit the position information of the cover 106 to the main control system of the vehicle.

[0067] Specifically, when performing the charging operation, if the car needs to be charged with AC, the user can select the AC charging mode on the main control panel, and the main control system can control the charging seat cover 104 to open and expose the charging components. If the position sensor detects that the cover 106 is in the position of sealing the DC charging port 122, that is, the AC charging port 124 is in an exposed state, the user can directly connect the charging gun 101 to the AC interface 134 to charge the car; if the position sensor detects that the cover 106 is in the position of sealing the AC charging port 124, that is, the DC charging port 122 is in an exposed state, the main control system can control the actuator to drive the upper connecting rod 112 and / or the lower connecting rod 114 to pivot, so as to move the cover 106 from the position of sealing the AC charging port 124 to the position of sealing the DC charging port 122, so as to expose the AC charging port 124, and at this time, the user can connect the charging gun 101 to the AC interface 134 to charge the car. The user can also use the same method as the above operation to charge the car with DC.

[0068] For those skilled in the art, in some other embodiments, the actuator may not be provided, and the cover 106 can be switched between sealing the DC charging port 122 and the AC charging port 124 by manual operation of the user (by pinching the hand-held recessed portions 211 , 212 of the cover 106 with fingers).

[0069] Figures 4A-5B The diagram shows the state of use when the cover 106 seals the DC charging port 122 and the AC charging port 124 respectively. Figure 4A A front view showing the cover 106 in a position to seal the DC charging port 122, Figure 5A A front view showing the cover 106 in a position to seal the AC charging port 124, Figure 4B and 5B Along Figure 4A and 5A The cross-sectional view is taken along the section lines PP and QQ to illustrate the stop structure 208 of the cover 106 .

[0070] like Figure 4A-4B As shown, when the cover 106 is in the position of sealing the DC charging port 122, the DC sealing portion 204 of the cover 106 forms an interference fit with the DC charging port inner wall 142 of the DC charging port 122, thereby forming a sealed contact with the DC charging port 122. The stopper structure 208 of the cover 106 can abut against the end 432 of the DC interface 132, thereby limiting the axial movement of the cover 106 in the DC charging port 122.

[0071] like Figure 5A-5BAs shown, when the cover 106 is in the position of sealing the AC charging port 124, the AC sealing portion 206 of the cover 106 forms an interference fit with the AC charging port inner wall 144 of the AC charging port 124, thereby forming a sealed contact with the AC charging port 124. The stopper structure 208 of the cover 106 can abut against the end 434 of the AC interface 134, thereby limiting the axial movement of the cover 106 in the AC charging port 124.

[0072] The cover assembly of the present application has the following beneficial technical effects compared with the prior art:

[0073] First, in the present application, the two sealing parts (the DC sealing part 204 and the AC sealing part 206) of the cover 106 are arranged on the same side of the cover 106 facing the charging interface (the inner side of the vehicle body), so that no matter when the cover 106 is sealing the DC charging port 122 or the AC charging port 124, the two sealing parts will not be directly exposed to the external environment of the vehicle (dust, rain, etc.), thereby reducing the risk of the DC sealing part 204 and the AC sealing part 206 of the cover 106 being contaminated by the external environment, thereby reducing the risk of the DC charging port 122 and the AC charging port 124 and the charging interface components therein being contaminated.

[0074] Second, the present application uses a four-bar mechanism formed by the cover 106, the charging seat 111, the upper connecting rod 112 and the lower connecting rod 114, so that when the cover 106 switches from the sealed DC charging port 122 to the AC charging port 124 or from the sealed AC charging port 124 to the DC charging port 122, the cover 106 only moves horizontally but does not flip, so that the side of the cover 106 provided with the sealing part (DC sealing part 204 and AC sealing part 206) is always facing the side of the charging port (the inside of the vehicle body) during the entire movement process, thereby reducing the risk of the DC sealing part 204 and the AC sealing part 206 of the cover 106 being contaminated by the external environment during the process of switching the sealed charging port, thereby reducing the risk of the DC charging port 122 and the AC charging port 124 and the charging interface therein being contaminated.

[0075] Third, the present application drives the pivoting of the upper link 112 or the lower link 114 by setting an actuator connected to the main control system of the automobile, thereby controlling the cover 106 to switch between the positions of the sealed DC charging port 122 and the AC charging port 124; at the same time, the main control system is also configured to control the opening and closing of the charging seat cover 104, thereby preventing the user from directly touching the entire charging assembly 100 during the charging process of the car, which not only increases the convenience and controllability of the charging operation and adapts to the needs of integrated control of future electric vehicles, but also reduces the risk of accidental electric shock caused by the user directly touching the charging assembly.

[0076] Although the present application has been described in conjunction with the examples of the embodiments summarized above, it is obvious to those of ordinary skill in the art that various alternatives, modifications, changes, improvements and / or substantially equivalent solutions, whether known or currently or foreseeable in the near future, may be apparent. In addition, the technical effects and / or technical problems described in the present application are exemplary rather than restrictive; so the disclosure in the present application may be used to solve other technical problems and have other technical effects and / or may solve other technical problems. Therefore, the examples of the embodiments of the present application as stated above are intended to be illustrative rather than restrictive. Various changes may be made without departing from the spirit or scope of the present application. Therefore, the present application is intended to include all known or earlier developed alternatives, modifications, changes, improvements and / or substantially equivalent solutions.
