Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to an electric small door air blowing and heating auxiliary system. Background Art

[0002] At present, electric vehicles with a charging door are known. The charging door can be operably connected to a charging socket to close or open the charging socket. The charging socket is used to connect to a plug of a charging station outside the electric vehicle to provide power replenishment. During charging of the electric vehicle, the charging door keeps the charging socket open. During driving of the electric vehicle, the charging door keeps the charging socket closed.

[0003] In fact, electric vehicles need to be charged from time to time, so the charging door needs to be opened and closed frequently. In order to ensure the smooth opening and closing of the charging door, there must be a gap between the charging door and the vehicle sheet metal, or even a gap between the charging door and the charging socket, which may lead to water seepage and accumulation between the charging door and the door sheet metal.

[0004] In the case of water seepage and water accumulation mentioned above, when the electric vehicle is in severe low temperature weather, the remaining water in the gap can easily freeze the charging door to the door sheet metal or the charging socket, making the door unable to open normally or difficult to open. At this time, if hot water or tools are used to pry it open, the operation will be troublesome and the thawing effect will not be good. It may also cause damage to the vehicle body, causing trouble to the user.

[0005] A vehicle charging door anti-freezing device in the prior art, with publication number CN217533022U, includes a heating plate arranged on the door or base, the heating plate includes a heating layer and an insulating layer located on both sides of the heating layer, and electrode wires are respectively provided on the two electrodes of the heating layer, and the electrode wires can be electrically connected to the vehicle body power supply. For this anti-freezing device, it is necessary to arrange circuits inside the charging door. Figure 1 It can be seen that the electrode wire needs to extend from the base and be connected to the small door. In the charging state, the electrode wire is inevitably exposed to the external space, and the electrode wire needs to move with the charging small door, which may cause wear and damage, and is not conducive to long-term use.

[0006] Another anti-icing structure for a vehicle charging door in the prior art is disclosed in publication number CN116001604A. It also uses a heating pad to heat the gap between the inner door cover and the outer door cover. As for the connection method of the heating pad, the patent provides a terminal block that can be electrically connected to an external power supply through a terminal block combined with a wire. A terminal insertion portion is formed on the inner side of the inner door cover, and the terminal insertion portion is connected to the terminal block. However, if a plug-in power-on method is adopted, the charging door cannot perform heating work when it is open, and when the charging door is rotated to the closed state, it is inconvenient for the terminal insertion portion on the rotating track of the charging door to engage with the terminal block on the charging socket. If a terminal contact power-on method is adopted, the conductive part of the terminal will still be exposed when the charging door is open.

[0007] Regarding the two related patents mentioned above, both adopt the method of embedding an electric heating pad in the charging door to implement ice-breaking heating. This method is bound to occupy the internal space of the charging door, causing wiring difficulties, and the thickness of the charging door in its vertical direction is increased. Compared with the traditional non-heated charging door, it is necessary to make larger structural modifications to the original charging door and charging socket, and the implementation cost is high. What is important is that with this electric heating pad method, heat needs to be conducted to the frozen position through the charging door, there is heat loss, and the ice-melting efficiency is low. In addition, the above-mentioned electric heating pad is only arranged on the contour side of the charging door. If there is ice inside the charging socket, the electric heating pad cannot effectively melt the ice inside the charging socket. Summary of the Invention

[0008] In view of the deficiencies in the prior art, the present invention aims to provide an electric small door blowing and heating auxiliary system.

[0009] The above technical objectives of the present invention are achieved through the following technical solutions: an electric door blowing and heating auxiliary system, comprising: a charging housing, built into an opening of a door sheet metal, the charging housing forming an inner cavity within the door sheet metal, and a charging plug module provided on the charging housing, the charging plug module being configured to engage with a charging gun;

[0010] A charging door is rotatably connected to the charging housing and closes or opens the inner cavity, with an open space formed between the charging door and the door sheet metal;

[0011] The heating auxiliary system includes a heating input channel connected to the inner cavity and a heat source for outputting heat flow. The heating channel guides the heat flow into the inner cavity and acts on the open space. The charging door is also provided with a heating output channel that allows the heat flow to be output to the open space.

[0012] Furthermore, the charging door includes:

[0013] A driving arm, one end of which is movably connected to the charging housing, and the other end of the driving arm forms a connecting portion;

[0014] The charging cover is located at the connection part and exposed on the door sheet metal.

[0015] Furthermore, the heating output channel is formed in the driving arm, and an input port and an output port are provided on the driving arm. The input port is connected to the inner cavity and / or the heating input channel, and the output port is connected to the heating output channel and the open space.

[0016] Furthermore, the outer contour of the connecting portion, the opening of the door sheet metal and the charging outer cover define an open space, and a sealing component is provided in the open space to isolate the inner cavity. The sealing component is arranged in any one or more of the connecting portion, the charging outer cover and the charging shell.

[0017] Furthermore, the contour of the connecting portion extends relative to the door sheet metal opening and at least partially shields the charging housing.

[0018] Furthermore, a compartment is formed between the charging cover and the driving arm, and the compartment allows heat to flow into it and be released to the open space.

[0019] Furthermore, the charging door is provided with an input port connected to the heating input channel or the inner cavity, and an output port connected to the heating output channel and the open space, and the input port and the output port are both arranged at a relatively lower position of the charging door.

[0020] Furthermore, the driving arm is provided with a plurality of staggered ribs facing the charging cover, and the plurality of ribs are arranged at different heights in the vertical direction of the vehicle door, and heat flow guiding channels are formed between adjacent ribs.

[0021] Furthermore, the charging housing is divided into a first area matching the profile of the transmission end of the driving arm, and a second area matching the connecting portion, and the input port is arranged in the first area, or at an adjacent position between the first area and the second area.

[0022] Furthermore, the heating auxiliary system also includes an air outlet component for conveying heat flow toward the heating input channel and the inner cavity.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. By arranging the heating auxiliary system within the door sheet metal, the wiring of the heating auxiliary system can be hidden inside the door sheet metal, without affecting the structural installation of the charging housing or the rotation of the charging door, thereby ensuring the reliability and service life of the heating auxiliary system;

[0024] 2. When the open space between the charging door and the vehicle door sheet metal is frozen and cannot be opened, the heating auxiliary system is activated and outputs heat flow. The heat flow can enter the inner cavity of the charging shell through the heating input channel and enter the compartment through the input port on the driving arm. After fully acting on the charging door, the heat flow is finally output from the output port to the open space, thereby quickly unfreezing the charging door. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] It should be understood that although terms such as upper, middle, lower, top, end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0048] like Figure 1-11 As shown, the electric door blowing and heating auxiliary system 6 includes:

[0049] A charging housing 1 is built into an opening 2.1 of a vehicle door sheet metal 2. The charging housing 1 forms an interior cavity 1.1 within the vehicle door sheet metal 2. The charging housing 1 is provided with a charging plug module 3 for engaging with a charging gun to provide power to the electric vehicle.

[0050] The charging door 4 can move relative to the fixed charging shell 1 and the vehicle door sheet metal 2 through a driving mechanism 11, thereby closing or opening the inner cavity 1.1, and when the charging door 4 is in the closed position, an open space 5 is formed between the charging door 4 and the vehicle door sheet metal 2. The open space 5 actually refers to the movement gap between the charging door 4 and the vehicle door sheet metal 2. In harsh environments such as low temperature and heavy snow, there is freezing in the open space 5. In other cases, if the inner cavity 1.1 of the charging shell 1 is affected by the assembly gap or other factors, the inner cavity 1.1 of the charging shell 1 also has the above-mentioned freezing phenomenon.

[0051] To this end, the present invention also adds a heating auxiliary system 6, including a heating input channel 6.1 connected to the inner cavity 1.1, and a heat source 6.2 for outputting heat flow. The heating input channel 6.1 can guide the heat flow into the inner cavity 1.1 and act directly or indirectly on the open space 5. A heating output channel 6.3 is also provided on the charging door 4. The heating output channel 6.3 is connected to the inner cavity 1.1, thereby allowing the heat flow in the inner cavity 1.1 to be output to the open space 5.

[0052] The above is a basic embodiment of the present invention. By transmitting heat flow in the inner cavity 1.1 of the charging shell 1 to ensure internal heat supply, ice-melting conditions are provided under extreme conditions. The heat flow can be connected to the charging door 4 and the open space 5 through the heating output channel 6.3 to provide ice-melting conditions between the vehicle door sheet metal 2 and the charging door 4, ensuring that the charging door 4 can melt quickly when frozen and can open smoothly under harsh low temperature conditions.

[0053] It can be concluded that the heat source 6.2 can be connected to the charging shell 1 through the heating input channel 6.1, and the heat flow in the inner cavity 1.1 can enter the charging door 4 and the open space 5 through the heating output channel 6.3. Therefore, there is no need to make too many changes to the current structure of the charging shell 1. It is only necessary to add the above-mentioned channel structure to the equipment side, which effectively reduces the design cost and mold cost and has strong applicability.

[0054] In addition, thanks to the fact that the heat source 6.2 is set inside the vehicle door sheet metal 2, the wiring of the heating auxiliary system 6 can be hidden inside the vehicle door sheet metal 2, which has no effect on the structural installation of the charging shell 1 and the rotation of the charging door 4, thereby ensuring the reliability and service life of the heating auxiliary system 6.

[0055] As a further embodiment of the charging door 4, the charging door 4 includes:

[0056] A driving arm 7, one end of which is movably connected to the charging housing 1, and the other end of the driving arm 7 forms a connecting portion 7.5;

[0057] The charging cover 8 is disposed on the connection portion 7.5 and exposed on the door sheet metal 2. The charging cover 8 serves as a covering member to close the opening 2.1 of the door sheet metal 2. When charging is required, the driving mechanism 11 and the driving arm 7 drive the charging cover 8 to open relative to the door sheet metal 2, thereby exposing the charging plug module 3.

[0058] The driving mechanism 11 is mounted on the charging housing 1 , and an output end of the driving mechanism 11 passes through the charging housing 1 and is connected to the driving arm 7 , thereby providing torque to the driving arm 7 .

[0059] Specifically, the charging door 4 is provided with an input port 6.4 connected to the heating input channel 6.1 or the inner cavity 1.1, and an output port 6.5 connected to the heating output channel 6.3 and the open space 5.

[0060] The above-mentioned heating output channel 6 . 3 can be arranged on the driving arm 7 , or between the driving arm 7 and the charging outer cover 8 .

[0061] It should be pointed out that the above-mentioned driving arm 7 can be an articulated arm, one end of which is connected to the driving mechanism 11 and is arranged in a hinged form on the charging shell 1, and the other end is connected to the charging outer cover 8. At the same time, there is no specific restriction on the number of driving arms 7 to meet the application of the heating auxiliary system 6 of the present invention in the rotating opening form of the charging door 4 and the translational opening form of the charging door 4 currently on the market.

[0062] Specifically, the outer contour of the connecting part 7.5, the opening 2.1 of the door sheet metal 2 and the charging outer cover 8 define an open space 5, so that the heat flow of the inner cavity 1.1 can indirectly act on the open space 5 through the above-mentioned charging door 4 components, and a sealing component is provided in the open space 5 to isolate the inner cavity 1.1. The sealing component is arranged in any one or more of the connecting part 7.5, the charging outer cover 8 and the charging shell 1. The sealing component is mainly used to ensure the sealing of the inner cavity 1.1 and the outside world.

[0063] As a further embodiment of the heating auxiliary system 6, the heating output channel 6.3 is formed in the driving arm 7, and an input port 6.4 and an output port 6.5 are provided on the driving arm 7, wherein the input port 6.4 can be connected to the inner cavity 1.1, and the heat flow in the inner cavity 1.1 is guided into the input port 6.4 to enter the heating output channel 6.3, and the output port 6.5 connects the heating output channel 6.3 and the open space 5. Through the above improvements, the driving arm 7 serves as an intermediate component for guiding the output of the heat flow, and conducts heat to the charging door 4. At the same time, the output port 6.5 can be set at any contour position of the driving arm 7.

[0064] As a variation of the input port 6.4, the input port 6.4 may also be directly connected to the heating input channel 6.1. In this variation, multiple heating input channels 6.1 may be optionally provided on the charging housing 1 to respectively connect the inner cavity 1.1 and the drive arm 7. Of course, the purpose of ice melting of the present invention may also be achieved by connecting only one of the inner cavity 1.1 or the drive arm 7.

[0065] like Figure 4 and Figure 5 As shown, as a further improvement to the driving arm 7, the outline of the connecting portion 7.5 on the driving arm 7 extends about the opening 2.1 of the vehicle door sheet metal 2 and at least partially shields the charging shell 1, and the heating output channel 6.3 is connected to the connecting portion 7.5, and the output port 6.5 is specifically arranged on the connecting portion 7.5. By increasing the shielding area of ​​the inner cavity 1.1 by the connecting portion 7.5, the supporting area of ​​the charging outer cover 8 is also increased, so as to increase the space in the charging door 4 to receive the heat flow, and facilitate the heat conduction of the driving arm 7 to the charging outer cover 8, thereby improving the ice melting efficiency.

[0066] In this embodiment, the outer contour of the inner cavity 1.1 of the charging shell 1 constitutes a connecting edge, which is pressed outside the opening 2.1 of the vehicle door sheet metal 2, and a first sealing ring 9 is embedded in the connecting edge. Under the restriction of the mounting component of the charging shell 1 located inside the vehicle door sheet metal 2, the first sealing ring 9 is pressed onto the opening 2.1 of the vehicle door sheet metal 2.

[0067] Furthermore, the outer contour of the connecting portion 7.5 is integrally formed with a second sealing ring 10, and the second sealing ring 10 has a skirt that tends to tilt toward the connecting edge of the charging shell 1. The joint between the second sealing ring 10 and the connecting portion 7.5 is slightly higher than the connecting edge of the charging shell 1 in the vertical direction of the vehicle door, so that when the charging door 4 is in the closed position, the second sealing ring 10 is pressed against the charging shell 1 in a deformed posture.

[0068] The first sealing ring 9 and the second sealing ring 10 serve as the above-mentioned sealing components to ensure the sealing between the charging housing 1 and the outside when the charging door 4 is in the closed position, thereby preventing the charging housing 1 from freezing.

[0069] like Figure 3 and Figure 7As shown, as a further implementation of the heating output channel 6.3, the driving arm 7 is provided with a plurality of staggered ribs facing the charging outer cover 8, and the plurality of ribs are arranged at different heights with respect to the vertical direction of the vehicle door, and a heat flow guiding channel is formed between adjacent ribs. Through the rib structure on the surface of the connecting portion 7.5 of the driving arm 7, a certain heat flow is retained, so that the heat flow fills the heat output channel, thereby improving heat conduction and heat utilization. Of course, the above-mentioned rib structure can serve as a structural reinforcement of the driving arm 7 itself, thereby reducing the equipment party's modification of the driving arm 7 structure and reducing design costs. At the same time, the equipment party can also adopt the existing rib structure on the driving arm 7 to achieve the guiding effect on the heat flow.

[0070] Furthermore, the drive arm 7 has a transmission portion 7.4 connecting the drive mechanism 11 and the connection portion 7.5. First ribs 7.1 are arranged between the transmission portion 7.4 and the connection portion 7.5 in a vertically spaced manner relative to the charging door 4. The plurality of first ribs 7.1 guide heat flow in a front-to-rear direction relative to the charging door 4.

[0071] The connecting portion 7.5 is also provided with second ribs 7.2 arranged in a grid-like cross pattern, and adjacent second ribs 7.2 are provided with spaced openings to allow the heat flow to fully act on the charging door 4. The driving arm 7 serves as an intermediate component and can simultaneously conduct heat to the inner cavity 1.1 and the charging outer cover 8.

[0072] Specifically, the connecting portion 7.5 is divided into a first area 7.51 that matches the contour of the transmission end of the driving arm 7, and a second area 7.52 that matches the connecting portion 7.5, wherein the division of the first area 7.51 and the second area 7.52 is mainly realized by the rib structure on the driving arm 7, and the first area 7.51 and the second area 7.52 extend in the front and rear directions of the charging door 4, and the second area 7.52 is arranged on the upper and lower sides of the first area 7.51, with the upper and lower boundaries of the contour of the connecting portion 7.5 serving as the outside of the second area 7.52, and the front and rear boundaries of the contour of the connecting portion 7.5 serving as the outside of the first and second areas 7.52. Preferably, the heat flow entering the heating output channel 6.3 is guided by the rib structure and transported from the front to the rear of the first area 7.51.

[0073] The input port 6.4 is arranged in the first area 7.51, or at the adjacent position of the first area 7.51 and the second area 7.52, so that the heat flow can fully act on the first area 7.51 in the middle of the connecting part 7.5, and act on the second areas 7.52 on both sides. By planning the internal structure of the charging door 4, the heat flow can quickly fill the interior of the charging door 4.

[0074] Among them, the transmission part 7.4 can be optionally gooseneck-shaped. While the gooseneck-shaped transmission part 7.4 meets the rotation angle of the driving part in the charging shell 1, the heat flow input port 6.4 is arranged on the transmission part 7.4, and part of the heating output channel 6.3 is formed in the transmission part 7.4. For the conduction effect of the heat flow, one of them is that the transmission part 7.4 forms a transition channel 7.6 connecting the input port 6.4 and the heating output channel 6.3 in the heating output channel 6.3. The transition channel 7.6 tends to gradually expand in the direction of heat flow output, so as to facilitate the guidance and diffusion of the heat flow.

[0075] Preferably, the first rib 7.1 is arranged at the end of the transition channel 7.6, that is, guiding the heat flow to extend in one direction from the front to the rear of the charging door 4.

[0076] Among them, the connecting portion 7.5 is also provided with a third rib 7.3 extending in the front-to-rear direction of the charging door 4. The third ribs 7.3 are arranged at intervals on the upper and lower sides of the transition channel 7.6, thereby separating the first area 7.51 and the second area 7.52. The third ribs 7.3 are also provided with through openings at intervals to facilitate the passage of heat.

[0077] Through the above improvements, the heat flow input port 6.4 and the transition channel 7.6 are adjacent to and close to the transmission part 7.4 of the drive arm 7, so that the transmission part 7.4 for transmitting torque can preferentially withstand the action of the heat flow, thereby increasing the heating time at the torque-bearing part of the charging door 4, which is conducive to the rapid opening of the charging door 4 in a frozen state.

[0078] As a preferred embodiment of the present invention, a compartment 4.1 is formed between the charging cover 8 and the connecting portion 7.5 of the driving arm 7. The compartment 4.1 allows heat to flow into it and be released to the open space 5.

[0079] Specifically, based on the above embodiment, the charging cover 8 constitutes the outer boundary of the compartment 4.1, and the connecting portion 7.5 and the rib structure thereon constitute the inner boundary of the compartment 4.1, so that the heat flow can fully act on the charging door 4 to achieve rapid ice melting. Among them, the output port 6.5 is connected to the compartment 4.1, preferably arranged on the contour of the connecting portion 7.5 and located at the far end of the charging door 4 relative to the input port 6.4 and the transition channel 7.6, thereby ensuring that the heat flow is fully inside the charging door 4.

[0080] It should be pointed out that the above-mentioned rib structures are provided with a gap with the outer boundary of the charging door 4, and the heat flow can be distributed in the compartment 4.1 of the charging door 4 through the gap. As a result, the charging cover can adopt a flat plate to reduce the design cost. Of course, a guide structure can also be provided on the back of the charging cover to guide the heat flow.

[0081] On the basis of the above embodiment, the input port 6.4 and the output port 6.5 are further defined to optimize the transport of heat flow.

[0082] like Figure 7 As shown, specifically, the input port 6.4 and the input port 6.4 are both arranged at a relatively lower position of the charging door 4. The relatively lower input port 6.4 allows the heat flow to enter the heating output channel 6.3 during the upward process, and the relatively lower output port 6.5 allows the heat flow to fully act and be filled in the charging door 4 before being output from the output port 6.5. At the same time, by utilizing the upward tendency of the heat flow, the outer contour of the connecting portion 7.5 and the charging outer cover 8 can guide the heat flow so that the heat flow can fully act on the open space 5, and the outer contour of the charging door 4 adopts an arc setting with upward guidance.

[0083] like Figure 6 and Figure 9 As shown, preferably, the charging shell 1 is spatially planned according to the shape of the driving arm 7, based on the transmission part 7.4 and the connecting part 7.5 on the driving arm 7, the connecting part 7.5 matches the cavity of the charging shell 1, and its upper and lower dimensions are larger than the transmission part 7.4. Thus, the inner cavity 1.1 of the charging shell 1 is divided into a first space 1.2 matching the transmission part 7.4 and a second space 1.3 matching the connecting part 7.5. The first space 1.2 with smaller upper and lower dimensions is conducive to the conduction of heat flow toward the second space 1.3. Preferably, the input port 6.4 is arranged at the junction of the first space 1.2 and the second space 1.3.

[0084] At the same time, in the closed state, the gooseneck-shaped transmission part 7.4 is connected to the heating input channel 6.1, and the input heat flow can be guided by the transmission part 7.4 toward the input port 6.4 and the inner cavity 1.1 of the charging shell 1, so that the heat flow can quickly act on the open space 5.

[0085] In other embodiments, it is expected to ensure the ice-melting effect of the heat flow by limiting the open space 5, wherein the cavity contour formed by the connecting edge of the charging shell 1 is smaller than the opening 2.1 contour of the door sheet metal 2, the connecting portion 7.5 and the second sealing ring 10 thereon are adapted to the cavity contour of the charging shell 1, and the outer contour of the charging outer cover 8 matches the opening 2.1 contour of the door sheet metal 2. Therefore, the outer edge of the charging outer cover 8 can extend outside the cavity of the charging shell 1, and a movement gap is reserved between the charging outer cover 8 and the opening 2.1 of the door sheet metal 2. As a result, the outer edge of the charging outer cover 8 can play a role in shielding part of the open space 5, while limiting the escape of heat flow. The heat flow moves upward along the contour of the charging door 4 to fully act on the open space 5, thereby improving the ice-melting efficiency.

[0086] In the present invention, the heating auxiliary system 6 also includes an air outlet component 6.6 for transporting heat flow toward the heating input channel 6.1 and the inner cavity 1.1. The air outlet component 6.6 can be selected as a fan, and the volume of the fan can be planned according to the space within the vehicle door sheet metal 2. The heating input channel 6.1 connects the charging shell 1 and the fan. The heating input channel 6.1 can be selected as a hose connection with a certain degree of ductility, which is conducive to the adaptive adjustment of the position of the heat source 6.2 and the fan in the vehicle door sheet metal 2, and facilitates the spatial layout of the heating auxiliary system 6.

[0087] In the above embodiment, the heat flow is output from the inner cavity 1.1 of the charging shell 1 to the driving arm 7, and between the driving arm 7 and the charging cover. The heat flow in the inner cavity 1.1 can indirectly act on the open space 5 through the boundary between the cavity opening of the charging shell 1 and the connecting part 7.5. Preferably, the above boundary is sealed by a sealing member, and the sealing member is selected to be a material with good thermal conductivity, such as thermal conductive silicone, to improve heat conduction.

[0088] In order to solve the problem of discharging residual water after the open space 5 melts, the lower part of the charging door 4 of the present invention adopts a V-shaped profile, and the lower profile of the charging door 4 tends to deviate from the side of the output port 6.5, so that the residual water after melting is guided by this profile and gathered downward and discharged from the bottom of the open space 5. In addition, with the cooperation of the above-mentioned sealing component, the possibility of residual water entering the charging shell 1 is reduced. Under extreme conditions, for the residual water inside the charging shell 1, a drainage hole 1.4 is further provided at the bottom of the charging shell 1 on the basis of the above-mentioned V-shaped profile deviating from the output port 6.5.
