Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, in particular to a hydrogen filling port assembly. Meanwhile, the utility model also relates to a vehicle provided with the hydrogen filling port assembly. Background Art

[0002] A hydrogen fuel cell electric vehicle (FCEV) is a car that uses hydrogen fuel cells to generate electricity to drive an electric motor. It is different from traditional internal combustion engine cars and pure electric vehicles because it generates electricity through the chemical reaction of hydrogen and oxygen, rather than directly burning fossil fuels or relying on battery packs for power. Hydrogen fuel cell vehicles have many advantages such as good environmental protection and renewable fuel, but the explosion range of hydrogen is extremely large. Therefore, compared with oil vehicles that require the operator to perform static electricity removal operations themselves, hydrogen vehicles generally use static electricity clamps to release static electricity in convenient places on the vehicle to avoid static electricity igniting possible hydrogen leakage during hydrogen refueling. Static electricity can be directed to the hydrogen refueling machine through the static electricity clamp, and the hydrogen refueling machine is grounded, and finally the static electricity is released to the ground.

[0003] However, in order to reduce costs and prevent rust, most car body structures are generally treated with electrophoretic black paint and spray paint, which makes most car body structures non-conductive, and the optional clamping positions of the electrostatic clamp are limited when removing static electricity. If the wheel hub is supported by the electrostatic clamp, it may cause damage to the wheel hub, making it inconvenient to operate during hydrogenation and removing static electricity, and there is a risk of damaging the wheel hub. Utility Model Content

[0004] In view of this, the utility model aims to provide a hydrogenation port assembly, which can cooperate with the clamping of the electrostatic clamp to facilitate the removal of static electricity during hydrogenation.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A hydrogenation port assembly includes a mounting seat capable of conducting electricity, and a hydrogenation port and a conducting component arranged on the mounting seat;

[0007] The conductive component is electrically connected to the mounting seat, and has a clamping portion. The clamping portion and the hydrogen filling port are located on the same side of the mounting seat, and the clamping portion is used for being clamped by an external electrostatic clamp.

[0008] Furthermore, the clamping portion is driven to move relative to the mounting seat to switch between a hydrogenation state and a non-hydrogenation state;

[0009] In the hydrogenation state, the clamping portion is away from the mounting seat, and in the non-hydrogenation state, the clamping portion is close to the mounting seat.

[0010] Furthermore, the conductive component includes a conductive column having the clamping portion, and a slider disposed on the conductive column, and the slider extends along the axial direction of the conductive column to a side away from the clamping portion;

[0011] The conductive column is slidably disposed on the mounting seat, and corresponding to the clamping portion, the conductive column has a limit block extending along its own radial direction. In the non-hydrogenation state, the limit block abuts against the mounting seat. In the hydrogenation state, the slider slides out of the mounting seat and can abut against the mounting seat.

[0012] Further, the clamping portion has a boss protruding outwardly in the radial direction of the conductive column, and the boss is used to be clamped by the external electrostatic clamp;

[0013] The limiting block is arranged on the boss.

[0014] Furthermore, the clamping portion is provided at one axial end of the conductive column, and the sliding block extends to the end of the conductive column where the clamping portion is provided.

[0015] Furthermore, the conductive assembly includes a limiting member disposed on the conductive column, the limiting member protrudes outwardly in the radial direction of the conductive column and is used to limit the conductive column from sliding out of the mounting seat.

[0016] Further, the conductive component is connected to the mounting seat by welding; or,

[0017] The conductive component is screwed to the mounting seat.

[0018] Furthermore, a mounting hole is provided on the mounting seat, and the mounting seat can be mounted on the vehicle body by means of a fastener passing through the mounting hole.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] The hydrogenation port assembly described in the utility model is provided with a mounting seat, and a hydrogenation port and a conductive component with a clamping part are provided on the mounting seat, thereby hydrogenation can be achieved through the cooperation of the hydrogenation port and the hydrogenation gun, and at the same time, the conductive component can be used for being clamped by the electrostatic clamp to remove static electricity, so that the hydrogenation port assembly can provide a clamping basis for the electrostatic clamp, which is convenient for removing static electricity, and there is no need to clamp the electrostatic clamp on the body parts, which can prevent damage to the body parts, and thus can have a better use effect.

[0021] In addition, by setting the clamping part to be driven to move relative to the mounting seat and switch between the hydrogenation state and the non-hydrogenation state, not only can the static electricity be removed by cooperating with the electrostatic clamp during hydrogenation, but also the clamping part can be set close to the mounting seat in the non-hydrogenation state, which can have better aesthetics and help to improve the refinement of the hydrogenation port assembly.

[0022] Secondly, the conductive assembly includes a conductive column slidably mounted on the mounting seat, and a slider mounted on the conductive column, and a limit block is arranged on the conductive column, so that the clamping part can be switched between the hydrogenation state and the non-hydrogenation state by sliding and rotating the conductive column, with a simple structure and convenient operation. By making the clamping part have a boss protruding outward along the radial direction of the conductive column, it can facilitate electrostatic clamping.

[0023] In addition, by extending the slider to the end of the conductive column where the clamping part is provided, the slider can be always located in the slide groove of the mounting seat, which is convenient for guiding the conductive column to slide when the clamping part is switched from the non-hydrogenation state to the hydrogenation state, thereby improving the switching efficiency. By providing a limiter, the conductive column can be prevented from sliding out of the mounting seat, and the firmness of the conductive component on the mounting seat can be improved. The conductive component is welded to the mounting seat; or the conductive component is screwed to the mounting seat, both of which have the advantages of simple structure and easy design and implementation. By providing a mounting hole on the mounting seat, the hydrogen filling port assembly can be easily installed on the vehicle body.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0046] Embodiment 1

[0047] In order to prevent the hydrogen energy vehicle from being ignited by static electricity and possibly leaking hydrogen when refueling, an anti-static clamp is usually placed at a convenient location on the vehicle to release static electricity, so that the static electricity is directed to the hydrogenation machine through the anti-static clamp, and then grounded through the hydrogenation machine, and finally released to the ground. In the prior art, since the structure of most vehicle bodies 4 cannot conduct electricity, it is usually necessary to clamp the anti-static clamp of the hydrogenation station on the wheel hub during the anti-static operation, which is easy to damage the wheel hub, not only making the operation inconvenient during hydrogenation and anti-static, but also there is a risk of damaging the wheel hub.

[0048] To this end, this embodiment specifically proposes a new hydrogenation port assembly to solve the above-mentioned problem. The hydrogenation port assembly of this embodiment includes a mounting seat 1 capable of conducting electricity, a hydrogenation port 2 and a conductive component 3 arranged on the mounting seat 1. The conductive component 3 is electrically connected to the mounting seat 1, and the conductive component 3 has a clamping portion 3a. The clamping portion 3a and the filling port of the hydrogenation port 2 are located on the same side of the mounting seat 1, and the clamping portion 3a is used for clamping by an external electrostatic clamp.

[0049] The hydrogenation port assembly of this embodiment is provided with a mounting seat 1, and a hydrogenation port 2 and a conductive component 3 having a clamping portion 3a are provided on the mounting seat 1, so that hydrogenation can be achieved through the cooperation between the hydrogenation port 2 and the hydrogenation gun. At the same time, the clamping portion 3a of the conductive component 3 can be clamped by the electrostatic clamp to remove static electricity, so that the hydrogenation port assembly can provide a clamping basis for the electrostatic clamp, which is convenient for realizing static electricity removal, and there is no need to clamp the electrostatic clamp on other parts of the vehicle body 4, which can prevent damage to other parts of the vehicle body 4, and thus can have a better use effect.

[0050] Based on the above overall introduction, an exemplary structure of the hydrogenation port assembly of this embodiment is as follows: Figure 1As shown in the figure, only part of the body sheet metal for installing the hydrogen filling port assembly is illustrated in the figure, and the body 4 hereinafter specifically refers to the body sheet metal. For the convenience of processing and manufacturing, the mounting seat 1 of this embodiment is a plate-like structure as a whole. And, as a preferred embodiment, the mounting seat 1 is provided with a mounting hole 101, and the mounting seat 1 can be installed on the body 4 by a fastener passing through the mounting hole 101. The fastener can specifically be a bolt, which can cooperate with the nut 5 to install the mounting seat 1 on the body 4. Of course, in addition to screwing the mounting seat 1 to the body 4, it is also feasible to clamp or weld it to the body 4.

[0051] The conductive assembly 3 of this embodiment includes a conductive column 301 welded on the mounting seat 1, and one end of the conductive column 301 extends toward the side of the mounting seat 1 where the hydrogenation port 2 is provided, and is away from the mounting seat 1. The other end of the conductive column 301 is located on the other side of the mounting seat 1 and is welded to the mounting seat 1. In order to improve the connection firmness, a radially protruding convex piece 305 is provided at the end of the conductive column 301, and the conductive column 301 is welded to the mounting seat 1 through the convex piece 305.

[0052] The clamping portion 3a is disposed at one end of the conductive column 301 away from the mounting base 1, so as to facilitate the electrostatic clamping and prevent interference with the mounting base 1. In addition, in order to facilitate the clamping of the conductive column 301 with the electrostatic component, Figure 1 As shown in , corresponding to the clamping portion 3a, a boss protruding outward in the radial direction is provided on the conductive column 301. By providing the boss, the clamping of the electrostatic clamp can be further facilitated. At the same time, due to the large diameter of the boss, the electrostatic clamp can have a large clamping force, thereby improving the clamping firmness of the electrostatic clamp on the conductive column 301. In addition, in the specific implementation, in order to have a better conductive effect, the mounting seat 1 and the conductive component 3 can be made of stainless steel, which can prevent rust while being conductive, and is conducive to maintaining the aesthetics of the hydrogenation port assembly.

[0053] The hydrogen filling port assembly of the present embodiment, by adopting the above-mentioned structure, can be easily clamped by the electrostatic clamp, thereby realizing a conductive path of vehicle body sheet metal-hydrogen filling port 2-conductive component 3-electrostatic clamp-hydrogen filling station grounding, and can better remove static electricity during hydrogen filling. There is no need to clamp the electrostatic clamp at other positions of the vehicle body 4, which can prevent damage to other parts of the vehicle body 4 and facilitate operation.

[0054] Embodiment 2

[0055] This embodiment also relates to a hydrogenation port assembly, the overall structure of which is the same as that of the first embodiment, except that: Figure 2As shown in , the conductive column 301 is not provided with a convex piece, but with an external thread segment. At the same time, a limiting ring protruding outward along its own radial direction is provided on the conductive column 301, and the limiting ring is located on one side of the external thread segment, so that the limiting ring and the nut 5 can be respectively abutted against two opposite sides of the mounting seat 1 by screwing the external nut 5 with the conductive column 301, so that the conductive component 3 can be installed on the mounting seat 1 and the electrical connection between the two can be maintained, that is, the conductive component 3 and the mounting seat 1 can be electrically conductive.

[0056] The hydrogen filling port assembly of this embodiment, by adopting the above structure, can also be easily clamped by the electrostatic clamp, and can realize the conductive path of body sheet metal-hydrogen filling port 2-conductive component 3-electrostatic clamp-hydrogen filling station grounding, so as to better remove static electricity during hydrogenation.

[0057] Embodiment 3

[0058] This embodiment also relates to a hydrogenation port assembly, referring to Figures 3 to 6 As shown in , its overall structure is the same as that of the first embodiment. The difference is that the clamping portion 3a of this embodiment is driven to move relative to the mounting seat 1 and switch between the hydrogenation state and the non-hydrogenation state. In the hydrogenation state, the clamping portion 3a is away from the mounting seat 1, and in the non-hydrogenation state ( Figure 5 In the state shown), the clamping portion 3a is close to the mounting seat 1.

[0059] Based on the above design concept, as a preferred implementation method, combined with Figures 5 to 8 As shown in the figure, the conductive component 3 of this embodiment includes a conductive column 301 having a clamping portion 3a, and a slider 302 disposed on the conductive column 301, and the slider 302 extends along the axial direction of the conductive column 301 to a side away from the clamping portion 3a. The conductive column 301 is slidably disposed on the mounting seat 1, and corresponding to the clamping portion 3a, the conductive column 301 has a limit block 303 extending along its own radial direction. Figure 5 In the non-hydrogenation state shown, the limit block 303 abuts against the mounting seat 1 , while in the hydrogenation state, the slider 302 slides out of the mounting seat 1 and can abut against the mounting seat 1 so that the clamping portion 3 a is away from the mounting seat 1 .

[0060] In addition, as a preferred embodiment, Figure 8 As shown in FIG. 1 , the conductive column 301 of this embodiment is cylindrical, and the slider 302 is rectangular. Fig. 9As shown in , a socket 102 is provided on the mounting seat 1, and the socket 102 includes a first part 1021 and a second part 1022 connected to the first part 1021. The first part 1021 is a round hole matching the conductive column 301 and for the conductive column 301 to be inserted, and the second part 1022 is a rectangular hole matching the slider 302 and for the slider 302 to be inserted. The limit block 303 is a long strip extending along the radial direction of the conductive column 301, which can better keep the clamping part 3a on one side of the mounting seat 1 and facilitate operation, and switch the clamping part 3a to the hydrogenation state.

[0061] As a further embodiment, Figure 8 As shown in FIG. 1 , the clamping portion 3a is provided at one axial end of the conductive column 301, and the slider 302 extends to the end of the conductive column 301 provided with the clamping portion 3a. With such a configuration, when the clamping portion 3a is switched from the non-hydrogenation state to the hydrogenation state, the conductive column 301 can be guided to slide, thereby improving the switching efficiency. In addition, as a further embodiment, Figure 8 As shown in the figure, the clamping part 3a has a boss protruding outward along the radial direction of the conductive column 301, the boss is used for clamping by the external electrostatic clamp, and the limit block 303 is specifically arranged on the boss. The boss is specifically annular and arranged along the circumference of the conductive column 301. In addition, in this embodiment, by making the clamping part 3a have a boss protruding outward along the radial direction of the conductive column 301, it can facilitate electrostatic clamping.

[0062] Here, it should be noted that, in addition to providing a boss on the clamping portion 3a to facilitate the clamping of the electrostatic clamp, other structures may also be provided. For example, when the diameter of the conductive column 301 satisfies the clamping of the electrostatic clamp, a clamping groove may also be provided on the outer wall of the conductive column 301, and this structure also facilitates the clamping of the electrostatic clamp.

[0063] In addition, combined Figure 5 and Figure 8 As shown in , the conductive component 3 of this embodiment also includes a limiter 304 provided on the conductive column 301, and the limiter 304 protrudes radially outwardly along the conductive column 301, and is used to limit the conductive column 301 from sliding out of the mounting seat 1. By providing the limiter 304, the conductive column 301 can be prevented from sliding out of the mounting seat 1, and the firmness of the conductive component 3 on the mounting seat 1 can be improved. Among them, the limiter 304 of this embodiment is specifically a limiter ring sleeved on the conductive column 301, and it and the above-mentioned limiter block 303 are respectively provided at both ends of the conductive column 301. It can be understood that in addition to sleeve-mounting the limiter ring on the conductive column 301, the limiter ring and the conductive column 301 can also be integrally formed.

[0064] Based on the above overall description, the conductive component 3 of this embodiment is composed of Figure 5 When the non-hydrogenation state shown in is switched to the hydrogenation state, based on Figure 5 As shown in the state, first pull the clamping part 3a upwards, slide the bottom of the slider 302 out to the top of the mounting seat 1, and then rotate the conductive column 301 to make the slider 302 staggered with the second part 1022 of the slide slot. Finally, place the slider 302 above the mounting seat 1, and the clamping part 3a can be switched to the hydrogenation state away from the mounting seat 1, so that the electrostatic clamp can clamp the clamping part 3a to remove static electricity.

[0065] In addition, as another implementation, the conductive component 3 of this embodiment adopts Figure 8 The structure shown can also refer to the structure of a cylindrical pen in the prior art, which generally includes a housing, a locking member arranged in the housing, a pressure rod, a guide rail and a spring, and the housing is connected to the mounting seat 1, and each component must be made of a conductive material. Among them, the locking member is usually designed to have an inclined surface so that it can slide and rotate along the inclined surface when subjected to external force. The pressure rod is the operating part, that is, the clamping part 3a is arranged on the pressure rod, and the movement of the locking member can be driven by pressing the pressure rod. In addition, the pressure rod usually interacts with the locking member to achieve the extension and retraction of the pen core.

[0066] In addition, the guide rail provides a track for the locking member and the pressure rod to move. The bottom of the guide rail usually has an inclined surface that matches the locking member to ensure that the locking member can slide and rotate along it. The spring is located at the end to provide elastic force during the rising process of the pressure rod, helping the locking member to rotate along the inclined surface and lock in the appropriate position. Therefore, when the clamping part 3a is switched from the hydrogenation state to the non-hydrogenation state, the pressure rod is pressed, the pressure rod descends and pushes the locking member to slide and rotate along the inclined surface of the guide rail. During the rising process of the pressure rod, due to the elastic force of the spring, the locking member continues to rotate along the inclined surface until the pressure rod falls into the adjacent slot (extends out) and approaches the mounting seat 1.

[0067] When the clamping part 3a is switched from the non-hydrogenation state to the hydrogenation state, the pressure rod is pressed again, and the pressure rod descends again and pushes the locking member to slide and rotate along the inclined surface. During the ascending process of the pressure rod, the locking member rotates along the inclined surface again until the pressure rod falls into the adjacent slot of the locking member (retracted) and moves away from the mounting seat 1, thereby facilitating the electrostatic clamp clamping.

[0068] Based on the above overall description, the hydrogen filling port assembly of this embodiment can be easily clamped by the electrostatic clamp, so as to realize the conductive path of the body sheet metal-hydrogen filling port 2-conductive component 3-electrostatic clamp-hydrogen filling station grounding, and can better remove static electricity during hydrogenation. On the other hand, the clamping part 3a can be switched between the hydrogenation state and the non-hydrogenation state, and can cooperate with the electrostatic clamp to remove static electricity during hydrogenation. At the same time, the clamping part 3a can be placed close to the mounting seat 1 in the non-hydrogenation state, and can have better aesthetics, which is conducive to improving the exquisiteness of the hydrogen filling port assembly.

[0069] Embodiment 4

[0071] Furthermore, as a preferred embodiment, a nut 5 is provided on the vehicle body 4, and the mounting seat 1 is installed on the vehicle body 4 by screwing the bolts and the nut 5. Furthermore, in a specific implementation, the nut 5 can be made of copper to have a better conductive effect. Furthermore, during electrophoretic painting, the nut 5 can be shielded with tape to prevent the paint layer from entering the nut 5 and causing insulation. After painting, the tape is removed and the hydrogen filling port assembly is installed.

[0072] The vehicle of this embodiment is provided with the hydrogen filling port assembly of the first or second embodiment, so as to facilitate the removal of static electricity during hydrogen filling and improve the convenience of use. In addition, by providing the nut 5 on the vehicle body 4, not only static electricity can be removed during hydrogen filling, but also the installation of the hydrogen filling port assembly is also facilitated.
