Description

Technical Field

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

[0002] At present, automotive charging port boxes are generally designed with drainage holes to ensure that when rainwater or other liquids accidentally seep in, they can be quickly and effectively drained to protect the charging base from water damage.

[0003] However, during vehicle driving, due to the fact that the air flow velocity outside the vehicle is higher than that inside the charging port box, an air flow siphon effect will occur, causing the air inside the charging port box to flow outwards, generating negative pressure inside the charging port box. As a result, dust, fine particles and other impurities raised during the rolling of the wheels are carried by this high-speed air flow and inhaled into the charging port box, making it impossible to seal and dust-proof the drainage holes of the charging port box, leading to dust accumulation inside the charging port box and affecting the normal use of the charging base. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems in the related art to a certain extent.

[0005] For this purpose, an object of the utility model is to propose a charging port box that can not only achieve normal drainage of the drainage hole but also achieve sealing and dust-proofing of the drainage hole, ensuring the normal use of the charging base, thereby improving the service life of the charging port structure.

[0040] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0041] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0042] The charging port box, charging port structure and vehicle according to the embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0043] As Figure 1 shown, the charging port box according to the first aspect embodiment of the present utility model is assembled on the vehicle body 1. Among them, in order to increase the sealing performance between the charging port box and the vehicle body 1, a first sealing strip 13 can be provided at the connection between the charging port box and the vehicle body 1 to prevent dust from entering the charging port box through the connection between the charging port box and the vehicle body 1.

[0044] The charging port box can include a box body 10 and a baffle 11.

[0045] Among them, an installation cavity 100 is provided in the box body 10, and a drain hole 1000 communicating with the outside and the installation cavity 100 is opened in the box body 10, so as to drain the accumulated liquid in the installation cavity 100 to the outside through the drain hole 1000 when liquid (such as water or cleaning liquid) enters the installation cavity 100, thereby preventing the liquid from accumulating in the installation cavity 100. It should be noted that the drain hole 1000 of this embodiment is located Figure 1 inside the vehicle body 1 as shown. Among them, the direction in which the box body 10 points to the charging port cover 15 is the outside of the vehicle body 1, and the direction in which the charging port cover 15 points to the box body 10 is the inside of the vehicle body 1.

[0046] The baffle 11 is installed outside the box body 10, and the baffle 11 includes a first position and a second position.

[0047] Among them, with reference to Figure 2 , when the baffle 11 is in the first position, the baffle 11 blocks the drain hole 1000 to prevent external dust from entering the installation cavity 100 through the drain hole 1000.

[0048] With reference to Figure 3 , when the baffle 11 is in the second position, the baffle 11 opens the drain hole 1000 so that when liquid enters the installation cavity 100, the liquid inside the installation cavity 100 can be discharged.

[0049] It should be noted that in this embodiment, the material of the baffle 11 can be rubber material. By utilizing its elastic deformation ability, the matching degree with the drain hole 1000 can be improved, enabling the baffle 11 to closely fit the edge of the drain hole 1000, thus significantly enhancing the sealing effect when blocking the drain hole 1000, and further ensuring that external dust, dirt and other impurities are difficult to enter the installation cavity 100.

[0050] Specifically, the baffle 11 has two states: open and closed, and these two states are reflected by its position change. As Figure 2 shown, when the baffle 11 is in the first position, that is, the closed state, it can effectively block the drain hole 1000 and prevent dust, dirt and other impurities in the external environment from entering the installation cavity 100 through the drain hole 1000. This design ensures the cleanliness of the installation cavity 100, effectively avoids the phenomenon of dust accumulation inside the charging port box, and further extends the service life of the charging base 20.

[0051] On the other hand, as Figure 3 shown, when there is accumulated liquid in the installation cavity 100 that needs to be discharged, the baffle 11 can be moved to the second position, that is, the open state. At this time, the drain hole 1000 is opened and directly communicates with the outside. The liquid in the installation cavity 100 can be smoothly discharged through the drain hole 1000, thus avoiding the potential threat of water damage to the charging port structure.

[0052] Therefore, by setting the movable baffle 11 in this charging port box, not only the normal drainage function of the drain hole 1000 is ensured when needed, but also the high-efficiency sealing and dust prevention of the drain hole 1000 are realized, ensuring that the charging base 20 can be used normally, thus improving the service life of the charging port structure and providing users with a more lasting and stable charging experience.

[0053] Furthermore, with reference to Figure 1, the charging port box may further include a hinge 14 and a charging port cover 15. One end of the hinge 14 is hinged in the box body 10, and the other end of the hinge 14 is fixedly connected to the charging port cover 15. Moreover, the hinge 14 can rotate relative to the box body 10 to open or block the opening with the charging port cover 15. Wherein, a second sealing strip 16 is provided on the side of the charging port cover 15 close to the box body 10 to improve the sealing performance between the charging port cover 15 and the hinge 14 as well as between the charging port cover 15 and the box body 10.

[0054] In an embodiment of the present invention, as Figure 2 , Figure 3 and Figure 4 shown, a clamping portion 12 is provided on the outer wall of the box body 10. Among them, the clamping portion 12 can be integrally formed with the outer wall of the box body 10 to ensure the stability and compactness of the structure; it can also be firmly connected by an adhesive method; or, it can be stably installed on the outer wall of the box body 10 by using threaded parts to meet diverse installation requirements. Specifically, which method to adopt can be flexibly determined according to the actual application scenario and design requirements.

[0055] The baffle 11 is clamped on the clamping portion 12 and rotates relative to the clamping portion 12. The baffle 11 realizes the switching between the first position and the second position through rotation. Through the clamping method, the baffle 11 can be firmly installed on the box body 10, simplifying the assembly process. Moreover, the baffle 11 can rotate relative to the clamping portion 12. By rotating back and forth, the baffle 11 can realize the switching between the first position and the second position to open or block the drain hole 1000, with low cost and a compact structure.

[0056] To further clarify the previous embodiment, in an embodiment of the present invention, as Figure 4 and Figure 5 shown, the clamping portion 12 may include a head 120 and a root 121. One end of the root 121 is provided on the end face 1001 where the drain hole 1000 communicates with the outside. A clamping interface 110 is provided on the baffle 11, and the baffle 11 is clamped on the root 121 through the clamping interface 110 and is limited by the head 120. Among them, the maximum width of the size of the head 120 is greater than the width of the clamping interface 110, and the clamping interface 110 can be clamped on the root 121 after passing over the head 120. The head 120 is used to limit the root 121, thus avoiding the situation that the baffle 11 falls off from the root 121, and further ensuring the stability of the baffle 11 during rotation.

[0057] As a possible scenario, for the convenience of snap - fitting the baffle 11 to the root 121 through the snap - interface 110, one end of the head 120 away from the root 121 can be designed to be conical, and the shape starts from the head 120 and gradually narrows in the direction away from the root 121 to form a guide, enabling the baffle 11 to be more easily sleeved from the narrower part of the head 120. Moreover, the baffle 11 is made of rubber. Utilizing the elasticity of the rubber, the snap - interface 110 can be passed over the head 120 and snap - fitted onto the root 121, thus facilitating the snap - fitting of the baffle 11 to the root 121 through the snap - interface 110 and simplifying the installation process.

[0058] As another possible scenario, the diagonal dimension length of the snap - interface 110 is greater than the maximum dimension of the head 120. At the same time, the width of the snap - interface 110 is less than the maximum dimension of the head 120. When installing the baffle 11, rotate the baffle 11 so that its diagonal aligns with the head 120, enabling the baffle 11 to be installed in a diagonal manner. Subsequently, after rotation, it can be snap - fitted onto the root 121 and simultaneously limited by the head 120.

[0059] The baffle 11 has a clearance fit with the root 121 through the snap - interface 110 to rotate relative to the end face 1001. Utilizing the clearance between the snap - interface 110 and the root 121, that is, the dimension of the snap - interface 110 is greater than the dimension of the root 121, enables the baffle 11 to rotate relative to the end face 1001 and ensures that the baffle 11 will not encounter excessive resistance during the rotation process to achieve the switching between the first position and the second position.

[0060] Furthermore, as Figure 2 and Figure 3 shown, the end face 1001 is inclined upward in the direction away from the box body 10. The baffle 11 is adsorbed on the end face 1001 due to the air pressure difference inside and outside the installation cavity 100 to be in the first position. The baffle 11 is in a vertical state due to its own gravity and forms an angle a with the end face 1001 to be in the second position.

[0061] It should be noted that the degree of the angle a is greater than or equal to 30° and less than or equal to 60°. Thus, it can both facilitate the drainage of water through the drain hole 1000 and reduce the influence of the baffle 11 during drainage, and ensure that the baffle 11 is adsorbed on the end face 1001 due to the air pressure difference inside and outside the installation cavity 100 to guarantee the adsorption effect on the baffle 11. Among them, for example, the degree of the angle a can be 30°, 31°, 32°, etc., which can be set according to the actual situation.

[0062] Specifically, when the vehicle is in a stationary state, due to the inclined design of the end face 1001 and the natural action of gravity on the baffle 11, the baffle 11 will automatically assume a vertical state, forming a certain angle α with the end face 1001, thus being in the second position and opening the drain hole 1000. For example, during the car wash process, if water accidentally enters the charging port box, the accumulated water can smoothly drain through this open drain hole 1000, effectively avoiding the situation of water accumulation inside the charging port box.

[0063] When the vehicle is in a high-speed driving state, the situation is different. Since the air flow velocity outside the vehicle increases significantly, according to the basic principles of fluid mechanics, a relatively lower pressure will accompany the area with a higher flow velocity; in contrast, the air flow velocity inside the charging port box is relatively gentle, so the pressure is relatively higher. This difference in internal and external pressures forms an air pressure difference, causing the gas in the high-pressure area to flow towards the low-pressure area. And because it is difficult to achieve a completely sealed state between the charging port cover 15 and the box body 10, the air inside the charging port box will flow towards the outside of the vehicle body 1 through these tiny gaps. During this process, a negative pressure environment gradually forms inside the installation cavity 100, thereby generating a suction force. This suction force acts on the baffle 11 through the drain hole 1000. The specific air flow direction can be seen in the arrow indication in Figure 2 Under the action of this suction force, the baffle 11 will fit onto the drain hole 1000, effectively blocking the drain hole 1000, thus effectively preventing dust and other impurities from entering the inside of the charging port box (i.e., the installation cavity 100) through the drain hole 1000 and ensuring its internal cleanliness.

[0064] In another embodiment of the present utility model, a driving member (not shown in the figure) is installed outside the box body 10. The driving member is drivingly connected to the baffle 11, and the driving member can drive the baffle 11 to be in the first position and the second position.

[0065] Exemplarily, for example, the driving member can be a micro pneumatic or hydraulic component. By controlling the telescopic end of the driving member, the baffle 11 can be driven to move back and forth to achieve the switching of the baffle 11 between the first position and the second position, thereby opening or blocking the drain hole 1000. Among them, the driving member can be connected to the processor in the vehicle's central control. When the processor detects that the vehicle is in a driving state, it can intelligently control the driving member to move the baffle 11 to the first position to ensure that the drain hole 1000 is blocked; when the processor determines that the vehicle is in a stationary state, it will instruct the driving member to adjust the baffle 11 to the second position so that the drain hole 1000 can drain smoothly.

[0066] For another example, the driving member can also be a linear motor, which also has the ability to drive the baffle 11 to move back and forth, so as to drive the baffle 11 to move back and forth to realize the switching of the baffle 11 between the first position and the second position, thereby opening or blocking the drain hole 1000.

[0067] In an embodiment of the present invention, as Figure 3 and Figure 6 shown, along the direction from the opening of the installation cavity 100 pointing to the inside of the installation cavity 100, the bottom wall 101 of the installation cavity 100 is inclined downward, and the drain hole 1000 is arranged at the connection position of the side wall and the bottom wall 101 of the installation cavity 100. Among them, the inclined design of the bottom wall 101 can make the water flow converge in the installation cavity 100 and be discharged through the drain hole 1000, which not only ensures the smooth drainage in the installation cavity 100, but also can reduce the occurrence of water accumulation.

[0068] In an embodiment of the present invention, as Figure 6 shown, a first rounded corner 1002 is arranged at one end of the drain hole 1000 close to the baffle 11, and a second rounded corner 1003 is arranged at one end of the drain hole 1000 close to the installation cavity 100. The design of the rounded corners can significantly reduce the resistance when the water flow passes through. Especially when the water flow encounters sharp corners, it is easy to generate tension and hinder the flow. By setting the first rounded corner 1002 and the second rounded corner 1003, this kind of tension can be effectively eliminated, so that the water flow can pass through the drain hole 1000 more smoothly, ensuring the smoothness of the water flow. Among them, the radius of the first rounded corner 1002 and the second rounded corner 1003 R≥0.5mm. For example, the radius of the first rounded corner 1002 and the second rounded corner 1003 can be 0.5, 0.51, 0.52, etc.

[0069] As Figure 1 shown, the charging port structure of the second aspect embodiment of the present invention further includes a charging base 20 and a charging port box according to the above first aspect embodiment of the present invention. The charging base 20 is partially placed in the box body 10, and the charging base 20 is hermetically connected to the box body 10.

[0070] According to the charging port structure of the present invention, through the above charging port box, not only the normal drainage function of the drain hole 1000 when needed is ensured, but also the efficient sealing and dust prevention of the drain hole 1000 are realized, reducing the influence of dust on the charging base 20, thereby greatly improving the service life of the charging port structure.

[0071] Furthermore, in order to realize the sealed connection between the charging base 20 and the box body 10, a third sealing strip 21 can be arranged between the charging base 20 and the box body 10 to increase the sealing performance between the two, so as to prevent dust from entering the charging port box through the gap between the charging port box and the charging base 20.

[0072] It should be noted that the explanations of the foregoing embodiments of the charging port box are also applicable to the charging port structure of this embodiment, and will not be elaborated here.

[0073] As Figure 1 shown, a charging port box according to an embodiment of the third aspect of the present invention, a vehicle, includes a vehicle body 1 and a charging port structure according to the above-mentioned second aspect embodiment of the present invention. The charging port structure is installed on the vehicle body 1. Among them, the vehicle can be a hybrid vehicle or an electric vehicle.

[0074] It should be noted that the explanations of the foregoing embodiments of the charging port structure are also applicable to the vehicle of this embodiment, and will not be elaborated here.

[0075] In summary, the charging port box, the charging port structure and the vehicle according to the embodiments of the present invention can not only achieve normal drainage of the drainage holes, but also achieve sealing and dust prevention of the drainage holes, ensuring the normal use of the charging seat, thereby improving the service life of the charging port structure.
