Description

Technical Field

[0001] The utility model relates to the field of vehicles, and in particular to a charging port box device and a vehicle. Background Art

[0002] A charging port box device is a device used on new energy vehicles to connect to external charging equipment. It consists of a box body and a cover assembly. The box body is embedded in the vehicle body and has an opening facing the outside of the vehicle body. The inside of the box body is equipped with a charging port structure for plugging in external charging equipment. The cover assembly is hinged to the box body, allowing the cover assembly to open and close the box body opening.

[0003] In the related art, a push switch is provided on the box body for controlling the opening of the cover assembly. When the cover assembly is fully closed, the cover assembly corresponds to the pressing end of the push switch. When the cover assembly needs to be opened, the user presses the cover assembly, causing it to produce an appropriate amount of elastic deformation, which in turn causes the cover assembly to contact the push switch, triggering the push switch and controlling the opening of the cover assembly.

[0004] To limit the closed position of the box, one related technique employs a limit slot on the corresponding surface of the box body and the cover assembly, with the limit slot positioned adjacent to the push switch. The cover assembly is also provided with a limit rib that corresponds to the limit slot. When the cover assembly is fully closed, the limit rib enters the limit slot, which restricts further movement of the limit rib into the slot, thereby limiting further movement of the cover assembly toward closing.

[0005] However, with this type of charging port box device, when the cover assembly is opened, the limiting ribs and limiting grooves are exposed to the outside, which can easily cause the following problems: 1. The limiting ribs and limiting grooves affect the appearance of the vehicle; 2. The limiting grooves are exposed to the outside, which can easily retain dust and impurities and are difficult to clean; 3. The limiting ribs and limiting grooves are exposed to the external environment and can easily be deformed by the external environment, resulting in abnormal noise when the limiting ribs and limiting grooves are engaged.

DETAILED DESCRIPTION

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0041] An embodiment of the present invention provides a charging port box device, which is a device used to protect the charging port structure of an electric vehicle or other equipment from dust, moisture and physical damage.

[0042] like Figures 1 to 4 As shown, the charging port box device includes a box body 11 and a box cover assembly 10. The box body 11 has an inner cavity 111. The charging port structure for docking with an external charging device is arranged in the inner cavity 111 of the box body 11. The inner cavity 111 has an opening 112.

[0043] The box cover assembly 10 includes a cover body 101 and a hinge 102. The hinge 102 has a first end 1021 and a second end 1022 opposite to each other. The first end 1021 of the hinge 102 is hingedly connected to the box body 11, and the second end 1022 of the hinge 102 is connected to the cover body 101. Specifically, the first end 1021 of the hinge 102 can be hingedly connected to the box body 11 via a pin 116, and the second end 1022 of the hinge 102 can be fixedly connected to the cover body 101 via a connector such as a screw or a pin. Of course, the second end 1022 of the hinge 102 and the cover body 101 can also be formed into an integral structure through an injection molding process.

[0044] With this arrangement, the cover 101 is rotatably connected to the housing 11 via the hinge 102, allowing the cover 101 to switch between an open and closed state. In the open state, the charging port structure within the inner cavity 111 of the housing 11 is exposed, allowing external charging devices to connect to the charging port structure. In the closed state, the charging port structure is enclosed within the inner cavity 111 of the housing 11, thereby protecting it from dust, moisture, and physical damage.

[0045] It should be noted that in order to ensure that the closed position of the cover body 101 is stably in a specific position, a limiting structure is designed between the cavity wall of the inner cavity 111 and the hinge 102 in this embodiment. The limiting structure includes a limiting protrusion 1025 and a limiting mating surface 1133. One of the limiting protrusion 1025 and the limiting mating surface 1133 is set on the cavity wall of the inner cavity 111, and the other is set on the hinge 102.

[0046] In one embodiment, a limiting protrusion 1025 is provided on the hinge 102. The limiting protrusion 1025 may be cylindrical, frustum-shaped, or the like. The limiting protrusion 1025 can abut against the limiting mating surface 1133, thereby forming a limiting effect.

[0047] A limiting mating surface 1133 is provided on the cavity wall of the inner cavity 111. The limiting mating surface 1133 serves as a surface for the limiting protrusion 1025 to abut against. The limiting mating surface 1133 may be a local wall surface on the cavity wall of the inner cavity 111 of the box body 11. When the box body 11 is closed into place, the limiting protrusion 1025 just abuts against the limiting mating surface 1133 to limit the box body 11 from continuing to rotate in the closing direction.

[0048] In another embodiment, a limiting protrusion 1025 is provided on the wall of the inner cavity 111, and a limiting mating surface 1133 is provided on the hinge 102. The limiting mating surface 1133 may be a partial surface of the hinge 102. When the box body 11 is fully closed, the limiting mating surface 1133 abuts against the limiting protrusion 1025 to prevent the box body 11 from further rotating in the closing direction.

[0049] In this way, the limiting protrusion 1025 can be set on the wall of the inner cavity 111 of the hinge 102 or the box body 11, and in particular, can be set in a relatively hidden position of the hinge 102 or the inner cavity 111 of the box body 11, that is, when the cover body 101 is in the open state, the limiting protrusion 1025 will not be exposed to the outside, thereby avoiding the problems in the related technology such as the limiting structure being exposed to the outside, affecting the appearance of the vehicle, easily retaining dust and impurities, and being easily deformed by the external environment and causing abnormal noise.

[0050] In a further embodiment, the box body 11 includes a box bottom 114 and a box side wall 115, and the box bottom 114 is arranged opposite to the opening 112. The box side wall 115 is arranged between the box bottom 114 and the opening 112, connecting the box bottom 114 and the opening 112 to form the side wall structure of the box body 11. It should be understood that the opening 112 of the box body 11 is used to allow an external charging device (for example, a charging gun of a charging pile) to enter the inner cavity 111 of the box body 11 when the cover body 101 is open, and to dock with the charging port structure in the inner cavity 111 of the box body 11. The box bottom 114 is arranged opposite to the opening 112, and the box bottom 114 can be provided with an installation port, which can allow the charging port structure to be installed in the inner cavity 111 of the box body 11.

[0051] In this embodiment, the accommodating groove 113 is arranged on the box side wall 115, and the slot 1134 of the accommodating groove 113 is arranged on the box side wall 115, so that the slot space of the accommodating groove 113 is in communication with the inner cavity 111 of the box body 11. Specifically, the accommodating groove 113 and the box body 11 can be formed in an integrated structure by an injection molding process, and the accommodating groove 113 protrudes from the box side wall 115. In this way, the accommodating groove 113 can be regarded as a part of the box body 11, and the slot space of the accommodating groove 113 can be regarded as a part of the inner cavity 111 of the box body 11.

[0052] The main function of the accommodating groove 113 is to accommodate part of the structure of the hinge 102, especially when the cover body 101 is in a closed state, part of the structure of the hinge 102 is located in the accommodating groove 113. In this way, the space utilization of the inner cavity 111 of the box body 11 can be improved, and the overall volume of the box body 11 can be reduced.

[0053] The limiting protrusion 1025 or the limiting matching surface 1133 is arranged on the groove wall of the accommodating groove 113. Specifically, if the limiting protrusion 1025 is arranged on the groove wall of the accommodating groove 113, then the limiting matching surface 1133 needs to be arranged on the hinge 102; otherwise.

[0054] When the cover body 101 switches from an open state to a closed state, the hinge 102 will rotate and partially enter the accommodating groove 113. In this process, the limiting protrusion 1025 or the limiting matching surface 1133 will gradually approach and eventually abut the corresponding structure on the hinge 102. Once the limiting protrusion 1025 abuts the limiting matching surface 1133, it will jointly prevent the cover body 101 from continuing to rotate, thereby ensuring that the cover body 101 is in the correct closed position.

[0055] In this way, the limiting protrusion 1025 and the limiting matching surface 1133 can be arranged inside the accommodating groove 113, which is more easily hidden, thereby further avoiding the problem of exposure of the limiting structure.

[0056] In a further embodiment, as shown in Figure 2 The accommodating groove 113 includes a groove bottom 1131 and a groove side wall 1132. The groove bottom 1131 is arranged opposite to the slot opening 1134 of the accommodating groove 113, and the groove side wall 1132 is arranged between the groove bottom 1131 and the slot opening 1134, that is, the groove bottom 1131 and the groove side wall 1132 jointly form the accommodating groove 113 with the slot opening 1134. The limiting protrusion 1025 or the limiting matching surface 1133 is arranged on the groove bottom 1131 of the accommodating groove 113. In this way, the limiting protrusion 1025 or the limiting matching surface 1133 is arranged on the groove bottom 1131 of the accommodating groove 113 and hidden in a deep position of the accommodating groove 113, which has a better hiding effect.

[0057] In a further embodiment, hinge 102 includes a first hinge segment 1023 and a second hinge segment 1024 connected sequentially along its first end 1021 to its second end 1022. First hinge segment 1023 and second hinge segment 1024 form a bent structure. Specifically, first hinge segment 1023 and second hinge segment 1024 can be formed into a one-piece structure through an injection molding process, and the connection between the two can be transitioned through an arc-shaped structure.

[0058] When the lid 101 is covering the opening 112, the first hinge segment 1023 corresponds to the groove bottom 1131, and the limiting protrusion 1025 or the limiting mating surface 1133 is provided on the first hinge segment 1023. Specifically, when the lid 101 is covering the opening 112, the first hinge segment 1023 extends from the opening 112 of the box body 11 to the box bottom 114, and the second hinge segment 1024 extends from the box bottom 114 of the box body 11 to the opening 112 and is connected to the lid 101. When the lid 101 is covering the opening 112, the first hinge segment 1023 corresponds to the groove bottom 1131.

[0059] The limiting protrusion 1025 can be provided on the first hinge segment 1023. The limiting protrusion 1025 can be specifically made of a hard rubber material, and the limiting protrusion 1025 can be an integral injection-molded structure with the first hinge segment 1023. The limiting protrusion 1025 is provided on the side surface of the first hinge segment 1023 near the bottom 1131 of the receiving groove 113. Correspondingly, the limiting mating surface 1133 is located on the bottom 1131 of the receiving groove 113. A portion of the bottom 1131 of the receiving groove 113 can serve as the limiting mating surface 1133. That is, when the cover 101 is closed, the limiting protrusion 1025 abuts against the bottom 1131. The position where the limiting protrusion 1025 abuts against the bottom 1131 constitutes the limiting mating surface 1133 on the bottom 1131.

[0060] In a further embodiment, in order to facilitate the installation of the hinge 102, a first axial hole is provided on the side wall 1132 of the receiving groove 113, and a second axial hole is provided on the first end 1021 of the hinge 102, and the first axial hole and the second axial hole correspond to each other. Figure 5 As shown, a pin shaft 116 is provided in the first shaft hole and the second shaft hole. The pin shaft 116 is rotatably matched with the first shaft hole, and the pin shaft 116 is fixedly matched with the second shaft hole.

[0061] A pin 116 is provided in the first and second axial holes to ensure that the hinge 102 can be securely mounted on the receiving slot 113. The pin 116 is rotatably engaged with the first axial hole, while the pin 116 is fixedly engaged with the second axial hole on the hinge 102, allowing the hinge 102 and the pin 116 to simultaneously rotate about the axis of the first axial hole, thereby achieving the opening and closing function of the cover 101.

[0062] When connecting hinge 102 to receiving slot 113, first align first end 1021 of hinge 102 with sidewall 1132 of receiving slot 113, ensuring that the second axial hole aligns with the first axial hole. Then, insert pin 116 into the first and second axial holes to complete the installation of hinge 102. This installation method not only simplifies the installation process but also reduces the installation difficulty, making the assembly of the entire charging port box device more efficient and convenient.

[0063] In a further embodiment, the charging port box device also includes a driving device 12, which is arranged on the outer wall of the accommodating groove 113, and the end of the pin shaft 116 close to the driving device 12 is located outside the accommodating groove 113, and the end of the pin shaft 116 close to the driving device 12 is transmission-connected to the driving device 12.

[0064] Specifically, the driving device 12 may include a motor, which is fixed to the outer wall of the accommodating groove 113 by screws, pins and other connecting parts. This position ensures that there is enough space for the driving device 12 to be installed, and avoids it interfering with the layout and function inside the accommodating groove 113.

[0065] One end of the pin shaft 116 close to the driving device 12 extends to the outside of the accommodating groove 113, and the protruding end of the pin shaft 116 can be provided with a transmission tooth, and the output shaft of the motor can also be provided with a transmission tooth. The motor and the pin shaft 116 realize transmission connection through the cooperation of the transmission teeth.

[0066] When the driving device 12 is activated, it can transmit power to the hinge 102 through the pin 116, thereby driving the cover 101 to open and close. For example, when the driving device 12 drives the pin 116 to rotate in a first direction, the cover 101 can be driven to open, and when the driving device 12 drives the pin 116 to rotate in a second direction, the cover 101 can be driven to close.

[0067] In a further embodiment, the charging port box device also includes a press switch 13, which is electrically connected to the driving device 12. The press switch 13 includes a pressing portion 131. The press switch 13 is used to trigger and control the driving device 12 to drive the cover body 101 to rotate in the opening direction when the pressing portion 131 is pressed.

[0068] The pressing switch 13 can be arranged at the edge of the opening 112 of the box body 11, and the pressing switch 13 is arranged opposite to the first end 1021 of the hinge 102. When the pressing part 131 of the pressing switch 13 is pressed, the driving device 12 drives the cover body 101 to open. Of course, in other embodiments, when the pressing part 131 of the pressing switch 13 is pressed, the driving device 12 can also drive the cover body 101 to close. For example, when the pressing part 131 is pressed for the first time, the driving device 12 drives the cover body 101 to open, and when the pressing part 131 is pressed for the second time, the driving device 12 drives the cover body 101 to close.

[0069] It should be noted that the cover body 101 has a certain elasticity. When the cover body 101 is in the closed state, under the limiting action of the limiting protrusion 1025 and the limiting matching surface 1133, a small gap 1136 is maintained between the cover body 101 and the corresponding surface of the pressing part 131. When a user presses the cover body 101 from the outside of the cover body 101, the cover body 101 is elastically deformed by a small amount, so that the cover body 101 can contact the pressing part 131, thereby triggering the pressing switch 13, and the pressing switch 13 controls the driving device 12 to drive the cover body 101 to open. When it is necessary to close the cover body 101, the user can directly touch the pressing part 131 by hand to trigger the pressing switch 13, and the pressing switch 13 controls the driving device 12 to drive the cover body 101 to close.

[0070] Since the limiting structure formed by the limiting protrusion 1025 and the limiting matching surface 1133 in the present scheme is in a concealed position of the charging port box device, it is not easily deformed by the external environment, thereby accurately controlling the closing position of the cover body 101, so that the cover body 101 always maintains a suitable gap 1136 with the pressing part 131 of the pressing switch 13 in the closed state. When the user presses the cover body 101, the cover body 101 is deformed and applies a suitable pressing force to the pressing part 131, so that the pressing switch 13 is triggered. If the limiting structure is deformed, the closing position of the cover body 101 will exceed the normal closing position, and the user pressing the cover body 101 will easily cause the pressing switch 13 to be pressed too much, thereby causing damage to the pressing switch 13. In the present scheme, the limiting structure formed by the limiting protrusion 1025 and the limiting matching surface 1133 is in a concealed position and is not easily damaged or deformed, thereby avoiding the problem of the pressing switch 13 being pressed too much and being damaged.

[0071] In further embodiments, in order to avoid the problem that the pin shaft 116 is pulled out of the first shaft hole and the second shaft hole, a retreat-stop structure is arranged between the pin shaft 116 and the second shaft hole, and the retreat-stop structure is used to limit the pin shaft 116 from being axially withdrawn from the second shaft hole.

[0072] In some embodiments, the retreat-stop structure can be realized in the following manner: Figure 5As shown, the second axial hole of the first end 1021 of the hinge 102 includes a large diameter portion 1135 and a small diameter portion. The inner diameter of the large diameter portion 1135 is larger than the inner diameter of the small diameter portion. In addition, the inner diameter of the large diameter portion 1135 is larger than the diameter of the pin 116, so that a certain gap 1136 is formed between the inner wall of the large diameter portion 1135 and the circumferential surface of the pin 116. The pin 116 and the small diameter portion can be interference fit to ensure a fixed connection between the pin 116 and the hinge 102. The back-stop structure can include a first limiting surface 1137 provided on the large diameter portion 1135 and a second limiting surface 1161 provided on the pin 116. The first limiting surface 1137 and the second limiting surface 1161 are both located within the gap 1136. In the direction of the back-off of the pin 116, the first limiting surface 1137 and the second limiting surface 1161 abut against each other.

[0073] Specifically, a first protrusion structure can be provided on the inner wall surface of the large-diameter portion 1135, and a second protrusion structure can be provided on the circumferential surface of the pin 116. When the pin 116 is installed in place, the first protrusion structure and the second protrusion structure have corresponding surfaces along the axial direction, which constitute the first limiting surface 1137 and the second limiting surface 1161. When the pin 116 has a tendency to exit, the first limiting surface 1137 and the second limiting surface 1161 abut against each other, thereby preventing the pin 116 from exiting the first and second axial holes.

[0074] Of course, in other embodiments, the large diameter portion 1135 may be provided with a protrusion structure, and the circumferential surface of the pin shaft 116 may be provided with a groove structure.
