[0046] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Reference Figure 1 to Figure 17 , a small sliding charging door in a car, comprising:

[0048] The charging port seat 7 has an inner cavity 1, an external opening 2 communicating with the inner cavity 1, and a charging interface 3 communicating with the inner cavity 1 and the battery assembly in the vehicle. Preferably, the charging port seat 7 includes a base body 4 and a base cover plate 6, and each accessory is placed therein during assembly, and finally the base cover plate 6 is fixed to the base body 4;

[0049] The charging port cover 8 can be installed in the charging port seat 7 in an openable and closable manner, and has at least a closed state and an open and hidden state. The charging port cover 8 is provided with a sliding foot assembly. Preferably, the charging port cover 8 is made by a two-color injection molding process, and includes a hard cover body 9 and a soft rubber 10 arranged on the outer ring of the cover body 9. The soft rubber 10 can cover the fitting gap and block foreign objects outside the vehicle;

[0050] The driving mechanism 11 is used to provide power to switch the charging port cover 8 between the closed state and the open hidden state. Preferably, the driving mechanism 11 includes a motor 12 and a rotating gear 13 connected to the motor 12, the flexible transmission rack 14 and the rotating gear 13 are meshed with each other to achieve transmission, and a protective cover 15 is also provided on the rotating gear 13, which can cover the rotating gear 13 and the flexible transmission rack 14 meshing with the rotating gear 13, playing a good protective role and preventing external impurities from invading and affecting normal use;

[0051] A flexible transmission rack 14, the input end of which is transmission-connected to the driving mechanism 11;

[0052] A transmission slider 16 is provided with a linkage groove 17, and the transmission slider 16 is transmission-connected to the output end of the flexible transmission rack 14;

[0053] The guide block 18 is provided with a guide track groove 19, the slide foot assembly is slidably arranged in the guide track groove 19 and can move along the guide track groove 19, and the slide foot assembly is also inserted into the linkage groove 17 to realize the transmission connection between the transmission slider 16 and the slide foot assembly. Preferably, the guide block 18 is made by a two-color injection molding process, including a hard guide block body 20 and a soft baffle 21 adapted to the guide track groove 19, the baffle 21 is used to partially seal and protect the guide track groove 19 to prevent larger foreign matter from invading and affecting the normal use of the interior.

[0054] In this embodiment, the transmission slider 16 is provided with an inner connecting portion 22 protruding inwardly, and the inner connecting portion 22 includes a first slide groove 23 and a first sliding portion 24; the guide block 18 is also provided with a second slide groove 25, and a second sliding portion 26 is protruding beside the second slide groove 25; the first sliding portion 24 is inserted into the second slide groove 25 and can slide along the second slide groove 25, and the second sliding portion 26 is inserted into the first slide groove 23 and can slide along the first slide groove 23. The structural arrangement of this embodiment forms a double sliding cooperation mode between the transmission slider 16 and the guide block 18, so that the combined sliding operation is more stable and reliable, and there will be no jamming or derailment.

[0055] Among them, the inner connecting portion 22 can be integrally formed with the transmission slider 16, or can be separately formed and then assembled together. The guide block 18 can be integrally formed with the charging port seat 7, or can be separately formed and then assembled together.

[0056] In order to achieve the connection and transmission effect between the flexible transmission rack 14 and the transmission slider 16, a preferred structural composition is proposed herein, specifically: a transmission groove 27 is also provided on the transmission slider 16, and a transmission part 28 is convexly provided on the flexible transmission rack 14, and the transmission part 28 is inserted in the transmission groove 27 to achieve the fixed connection between the flexible transmission rack 14 and the transmission slider 16. In this preferred structure, the transmission groove 27 is directly provided on the transmission slider 16, which can be used in conjunction with the transmission part 28 on the flexible transmission rack 14. The matching part of this preferred mode is directly integrated on the transmission slider 16 and the flexible transmission rack 14, so that the structure of this part is very simple, the difficulty of processing and assembly is relatively low, and the operation and use are also very reliable and smooth.

[0057] There are many kinds of composition forms of the sliding foot assembly, each with advantages and disadvantages. In the present embodiment, a preferred sliding foot assembly structure is proposed, which specifically includes a first sliding foot assembly and a second sliding foot assembly, wherein the guide track groove 19 includes a first track groove group 29 and a second track groove group 30, wherein the first sliding foot assembly is slidably arranged in the first track groove group 29, and the second sliding foot assembly is slidably arranged in the second track groove group 30. More specifically, the first sliding foot assembly includes two identical first sliding foot units 31, which are respectively protruded on both sides of the charging port cover 8; the second sliding foot assembly includes an active second sliding foot unit 32 and a driven second sliding foot unit 33, which are respectively protruded on both sides of the charging port cover 8, wherein the active second sliding foot unit 32 is inserted into the linkage groove 17 in the slider body. The double sliding foot structure composed of the first sliding foot assembly and the second sliding foot assembly adopted in this embodiment enables two sets of contact points to be present between the charging port cover 8 and the guide track groove 19, so that force can be evenly applied, so that the charging port cover 8 can move more smoothly during the process of opening or closing, and the relevant parts will not be damaged or broken due to excessive force.

[0058] In this embodiment, the guide track groove 19 has a curved section 34 and a straight section 35. The curved section 34 is provided to enable the charging port cover 8 to achieve position changes in multiple dimensions at the same time, so that it can fit with the irregular sheet metal of the vehicle body 43, eliminate the interference problem between components, and ensure the normal use of the system. At the same time, the existence of the curved section 34 plays a self-locking function in a specific period of time, preventing the charging port cover 8 from opening when an external force hits the vehicle, causing greater safety hazards.

[0059] Reference Figure 7 , for example, in one application, the second track groove group 30 is located above the first track groove group 29, the first track groove group 29 is straight, and the second track groove group 30 has a curved section 34 and a straight section 35. In the preferred structure, when the charging port cover 8 switches from the closed state to the open hidden state, one end of the charging port cover 8 always moves in translation, and the other end first tilts toward the charging port seat 7 and then moves in translation, thereby eliminating interference with the vehicle body 43 between state switching and completing the state switching.

[0060] In order to match the shape of the second trajectory groove group 30 and the movement trajectory of the active second sliding foot unit 32 to make the movement of the charging port cover 8 smoother, the linkage groove 17 is tilted in this embodiment, and the tilt direction of the linkage groove 17 is opposite to the tilt direction of the bending section 34.

[0061] When the active second sliding foot unit 32 is in the bending section, the force direction is inclined, and the inner wall of the second track groove group 30 and the active second sliding foot unit 32 are prone to slippage, thereby affecting the transmission effect. For this reason, the upper part of the linkage groove 17 is also provided with a positioning hole 36 that matches the shape of the active second sliding foot unit 32.

[0062] The charging port seat 7 is also provided with a limit groove 37, and the flexible transmission rack 14 is inserted into the limit groove 37. The setting of the limit groove 37 can constrain the flexible transmission rack 14 so that it will not jump out of the working position when it moves back and forth, thereby ensuring reliable transmission temperature. Preferably, an anti-dropping spring buckle 38 is provided at the notch of the limit groove 37, and the anti-dropping spring buckle 38 is against the flexible transmission rack 14; a stop spring buckle 39 is provided inside the limit groove 37, and a barb 40 is provided at the front end of the flexible transmission rack 14, and the stop spring buckle 39 and the barb 40 on the flexible transmission rack 14 are mutually locked and matched, thereby further limiting the flexible transmission rack 14.

[0063] The failure rate of electronic components is relatively high. Once the on-board computer or the drive mechanism 11 fails, the charging port cover 8 cannot be opened for use, which will cause the vehicle to be unable to travel due to insufficient power and need to be sent to a repair shop for repair. In an emergency, it is even necessary to call a towing service, which will cause great trouble to the user. For this reason, the present invention also includes an emergency manual pull cord 41, and a pull cord fixing groove 42 is also provided on the transmission slider 16. One end of the emergency manual pull cord 41 is fixed in the pull cord fixing groove 42 to achieve transmission coordination between the emergency manual pull cord 41 and the transmission slider 16. When the on-board computer or the drive mechanism 11 cannot be used, the user can pull the emergency manual pull cord 41 to open the charging port cover 8 to charge the vehicle.

[0064] When the present invention is applied to new energy vehicles, its working principle is as follows:

[0065] When charging is required, the on-board computer sends a command to the drive mechanism 11 to start the drive mechanism 11 to start running, and the drive mechanism 11 outputs power to the flexible transmission rack 14, thereby driving the transmission slider 16 connected thereto to move, so that the transmission slider 16 slides relative to the guide block 18, and the sliding foot assembly connected to the transmission slider 16 also moves therewith, so that the position of the charging port cover 8 relative to the charging port seat 7 changes, that is, it can be switched from the covered state to the open hidden state, so that the external opening 2 and the charging interface 3 are exposed, and the user can connect the external charging device to charge the battery assembly in the vehicle;

[0066] When charging is completed, the on-board computer sends a command to the drive mechanism 11 to make the drive mechanism 11 start to run in reverse. The drive mechanism 11 outputs power to the flexible transmission rack 14, and the flexible transmission rack 14 performs a reset movement, thereby driving the transmission slider 16 connected thereto to move, so that the transmission slider 16 performs a reverse translational slide relative to the guide block 18, and at the same time, the sliding foot assembly connected to the transmission slider 16 also moves in the opposite direction therewith, so that the position of the charging port cover 8 relative to the charging port seat 7 changes, that is, it can be switched from an open and hidden state to a covered state, and then the charging port cover 8 covers the external opening 2 and blocks the charging interface 3, and at the same time, the charging port cover 8 is integrated with the outer surface of the vehicle body 43.
