[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0042] The protective housing 100 of the hydrogenation module according to the first embodiment of the utility model is described below with reference to the accompanying drawings.

[0043] The protective housing 100 of the hydrogenation module according to the first aspect of the utility model is as follows Figure 1 and Figure 2As shown, the protective housing 100 includes: a first cover body 1, a second cover body 2, a door lock structure 3 and a buckle structure 4. The second cover body 2 is connected to the first cover body 1 to define a protective cavity 21, and the second cover body 2 can be opened and closed relative to the first cover body 1. The door lock structure 3 can selectively lock and unlock the first cover body 1 and the second cover body 2. When the door lock structure 3 locks the first cover body 1 and the second cover body 2, the first cover body 1 and the second cover body 2 cannot be opened and closed with each other, thereby closing the protective cavity 21 and protecting the components in the protective cavity 21; when the door lock structure 3 unlocks the first cover body 1 and the second cover body 2, the first cover body 1 and the second cover body 2 can be opened and closed with each other, so that the components in the protective cavity 21 can be operated.

[0044] It is worth noting that the protective shell 100 of the utility model is used for the hydrogenation module. The protective shell 100 can prevent external pollutants such as dust and water from entering the protective shell 100, reduce the pollution and damage to the hydrogenation module, thereby ensuring the cleanliness during the hydrogen fuel filling process, reducing the damage and failure of the system pipes, valves and non-metallic seals due to impurities, slowing down the life reduction rate of the hydrogenation module, and improving the safety of the use of the hydrogenation module.

[0045] Therefore, the locking of the protective housing 100 is very important to separate the protective cavity 21 from the external environment. The door lock structure 3 is arranged on the outside of the protective housing 100, and the door lock structure 3 includes: a rotating member 31 and a locking member 32. One end of the rotating member 31 is rotatably connected to the first cover body 1. The rotating member 31 has a locking position and an unlocking position. In the locking position, the other end of the rotating member 31 rotates to the second cover body 2 and cooperates with the locking member 32. In the unlocking position, the other end of the rotating member 31 is separated from the second cover body 2.

[0046] The rotating member 31 is rotatable, and the rotating member 31 rotates with one end of the rotating member 31 connected to the first cover body 1 as the rotation center. When the other end of the rotating member 31 rotates to the second cover body 2 and cooperates with the locking member 32, the rotating member 31 is located in the locking position, and the cooperation between the rotating member 31 and the locking member 32 connects the first cover body 1 and the second cover body 2 to achieve the locking of the protective housing 100. When the other end of the rotating member 31 rotates to be separated from the second cover body 2, the rotating member 31 is located in the unlocking position, and the first cover body 1 and the second cover body 2 can be opened and closed.

[0047] In addition to providing a door lock structure 3 on the outside of the protective housing 100, Figure 2 As shown, the protective housing 100 of the embodiment of the utility model is also provided with a buckle structure 4 inside. The buckle structure 4 includes a first buckle member 41 and a second buckle member 42 that match each other, one of which is provided on the first cover body 1 and the other is provided on the second cover body 2.

[0048] When the first cover body 1 and the second cover body 2 are locked, the door lock structure 3 connects the first cover body 1 and the second cover body 2 on the outside, the first buckle 41 and the second buckle 42 are engaged, and the buckle structure 4 connects the first cover body 1 and the second cover body 2 on the inside. By setting a double locking mechanism of the door lock structure 3 and the buckle structure 4, even if one of the door lock structure 3 and the buckle structure 4 fails, the other can still lock the protective shell 100 and separate the protective cavity 21 from the external environment, which can improve the protection reliability of the protective shell 100 and reduce the risk of the protective shell 100 accidentally falling off or opening during the operation of the vehicle.

[0049] Moreover, the buckle structure 4 can be matched and separated during the process of relatively opening and closing the first cover body 1 and the second cover body 2, which is easy to operate. While improving the protection reliability, it will not increase the difficulty of locking and unlocking the protective shell 100.

[0050] The door lock structure 3 is arranged on the outside, so it can be intuitively seen whether the door lock structure 3 has locked the first cover body 1 and the second cover body 2, which serves as a reminder.

[0051] According to the protective housing 100 of the embodiment of the utility model, by providing a double locking mechanism of the door lock structure 3 and the buckle structure 4, the protection reliability of the protective housing 100 can be improved, and the difficulty of locking and unlocking the protective housing 100 will not be increased. The door lock structure 3 is arranged on the outside, and it can be intuitively seen whether the door lock structure 3 locks the first cover body 1 and the second cover body 2, which plays a reminder role.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the door lock structure 3 also includes: a locking plate 33 provided on the second cover body 2, a locking groove 34 is formed between the locking plate 33 and the second cover body 2, a locking member 32 is provided on the locking plate 33, and the other end of the rotating member 31 rotates into the locking groove 34 when in the locking position.

[0053] By setting the locking piece 33, the locking member 32 can be arranged and the rotating member 31 can be positioned. When the other end of the rotating member 31 rotates into the locking groove 34, it means that the rotating member 31 rotates to the locking position. At this time, the locking member 32 and the rotating member 31 can be matched to lock the first cover body 1 and the second cover body 2.

[0054] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the upper end of the locking piece 33 is connected to the second cover body 2, and the lower end and left and right sides of the locking piece 33 are open. When the rotating member 31 rotates, the other end of the rotating member 31 enters the locking groove 34 from bottom to top and is limited by the upper end of the locking piece 33, thereby improving the matching accuracy of the rotating member 31 and the locking member 32.

[0055] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the locking member 32 is threadedly connected to the locking plate 33 , and in the locking position, the end of the locking member 32 presses against the rotating member 31 to lock the rotating member 31 .

[0056] The lock member 32 is a threaded member and is rotatably disposed on the lock plate 33. The threaded connection between the lock member 32 and the lock plate 33 allows the lock member 32 to tighten and loosen the lock plate 33 during rotation. The operation is simple, and the lock member 32 is not easy to get loose or lost. When the rotating member 31 rotates to the locking position, the lock member 32 rotates and moves toward the inside of the locking groove 34, and presses against the rotating member 31 to lock the rotating member 31 in the locking position, thereby locking the first cover 1 and the second cover 2.

[0057] In other embodiments of the present invention, the locking member 32 is threadedly connected to the locking plate 33, and a fixing hole is opened at the other end of the rotating member 31. When the rotating member 31 is rotated to the locking position, the locking member 32 rotates and moves toward the inside of the locking groove 34, passes through the fixing hole to lock the rotating member 31, so as to lock the protective shell 100.

[0058] In some other embodiments of the present invention, the locking member 32 is disposed on the locking piece 33 and is located in the locking groove 34, protruding toward the second cover body 2. When the rotating member 31 rotates to the locking position, the rotating member 31 squeezes in between the locking member 32 and the second cover body 2, and the end of the locking member 32 presses against the rotating member 31 to lock the rotating member 31, locking the rotating member 31 in the locking position, thereby locking the first cover body 1 and the second cover body 2.

[0059] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the door lock structure 3 further includes: a threaded fastener 35 , the threaded fastener 35 is connected to the rotating member 31 and is threadedly connected to the first cover body 1 , and the fastener is tightened to fix the rotating member 31 in the locking position.

[0060] The threaded fastener 35 can rotate relative to the first cover body 1, and the threaded fastener 35 is threadedly matched with the first cover body 1, and the matching stability of the threaded fastener 35 and the first cover body 1 is relatively strong. When the rotating member 31 rotates to the locking position, the threaded fastener 35 fixes the rotating member 31, prevents the rotating member 31 from rotating, and improves the connection stability of the rotating member 31 between the first cover body 1 and the second cover body 2.

[0061] In some embodiments of the present invention, the rotating member 31 is fixedly connected to the threaded fastener 35. After the threaded fastener 35 is tightened and fixedly matched with the first cover body 1, the rotating member 31 can be prevented from rotating relative to the first cover body 1, thereby improving the connection stability of the rotating member 31.

[0062] Optionally, the rotating member 31 and the threaded fastener 35 are integrally formed, which can improve the structural stability of the rotating member 31 and the threaded fastener 35 .

[0063] In other embodiments of the present invention, the rotating member 31 is rotatable around the threaded fastener 35. When the rotating member 31 is rotated to the locking position, the threaded fastener 35 is tightened to fasten the rotating member 31 to the first cover 1, preventing the rotating member 31 from rotating relative to the first cover 1, thereby improving the connection stability of the rotating member 31.

[0064] Optionally, a rotating hole is opened at one end of the rotating member 31 , and the threaded fastener 35 passes through the rotating member 31 and is fixedly connected to the first cover body 1 , and the rotating member 31 can rotate around the threaded fastener 35 .

[0065] In some embodiments of the present invention, Figure 3 As shown, the door lock structure 3 includes a first lock body 3a and a second lock body 3b, wherein the first lock body 3a is fixedly mounted on the first cover body 1, and the second lock body 3b is fixedly mounted on the second cover body 2. The rotating member 31 is rotatably connected to the first lock body 3a, and the threaded fastener 35 is connected to the first lock body 3a. The locking plate 33 is arranged on the second lock body 3b, and a locking groove 34 is formed between the locking plate 33 and the second lock body 3b.

[0066] In some embodiments of the present invention, the first lock body 3a is fixedly connected to the first cover body 1 through an M5 bolt assembly, and the second lock body 3b is fixedly connected to the second cover body 2 through an M5 bolt assembly.

[0067] In some embodiments of the present invention, Figure 1-Figure 3 As shown, with the coordinates shown in the figure as a reference system, the first cover body 1 and the second cover body 2 are opened and closed with the lower ends as the rotation axis. The door lock structure 3 is arranged on the front side of the protective shell 100, and there are two buckle structures 4, which are respectively arranged on the upper side and the rear side of the protective shell 100. The door lock structure 3 and the buckle structure 4 connect the three edges of the first cover body 1 and the second cover body 2 to each other, stably separate the protective cavity 21 from the external environment, and improve the protection reliability of the protective shell 100.

[0068] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the first snap fastener 41 is arranged on the second cover body 2, and the second snap fastener 42 is arranged on the first cover body 1. When the first cover body 1 and the second cover body 2 are buckled, the first snap fastener 41 and the second snap fastener 42 are snap-fitted to connect the first cover body 1 and the second cover body 2.

[0069] In some embodiments of the present invention, the first fastener 41 is fixedly connected to the second cover body 2 via an M5 bolt assembly, and the second fastener 42 is fixedly connected to the first cover body 1 via an M5 bolt assembly.

[0070] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the first latching member 41 includes a latching pin 411, and two opposite sides of the latching pin 411 are both latching surfaces 4111. Figure 5 As shown, there are two second locking members 42 , and the two second locking members 42 are respectively matched on the two locking surfaces 4111 .

[0071] When the first cover body 1 and the second cover body 2 are buckled, the latch 411 moves between the two second latch members 42, and the two second latch members 42 abut against the two opposite abutting surfaces 4111 of the latch 411. The two second latch members 42 clamp the latch 411, and the first cover body 1 and the second cover body 2 are connected to each other through the latch structure 4.

[0072] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the abutting surface 4111 is a curved surface and a concave surface.

[0073] The second fastener 42 is stopped and engaged on the abutting surface 4111. The two second fasteners 42 can not only clamp the pin 411 to limit the movement of the pin 411 along the spacing direction of the two second fasteners 42, but also limit the movement of the pin 411 in the length direction. The fit between the second fastener 42 and the abutting surface 4111 is tighter, thereby improving the fit stability between the first fastener 41 and the second fastener 42.

[0074] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the abutting surface 4111 is a curved surface and a concave surface, and the surface of the second clip 42 facing the clip 411 is a curved surface and a convex surface. The first clip 41 and the second clip 42 are more closely matched, which can improve the connection stability of the first cover 1 and the second cover 2. In addition, the curved surface design helps to disperse stress, reduce stress concentration between the first clip 41 and the second clip 42, and is conducive to extending the service life of the clip structure 4.

[0075] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the second fastener 42 includes: a retaining cylinder 421, a butt column 422 and a butt elastic member 423, one end of the retaining cylinder 421 is a cylinder mouth arranged toward the butt surface 4111, the butt column 422 is arranged in the retaining cylinder 421, the butt elastic member 423 is arranged in the retaining cylinder 421, one end of the butt elastic member 423 is connected to the retaining cylinder 421 and the other end is connected to the butt column 422 to press the butt column 422 toward the cylinder mouth, and the butt column 422 is pressed against the butt surface 4111 through the cylinder mouth.

[0076] The barrel openings of the two second fasteners 42 are arranged opposite to each other, and the abutting columns 422 of the two second fasteners 42 are respectively abutted and matched with the two abutting surfaces 4111 of the bayonet 411. The abutting elastic member 423 presses the abutting column 422 toward the barrel opening, and the abutting elastic member 423 presses the abutting column 422 tightly against the abutting surface 4111, so that the abutting column 422 and the abutting surface 4111 are more closely matched, thereby improving the matching stability of the first fastener 41 and the second fastener 42.

[0077] When the first latch 41 and the second latch 42 are separated, the abutting elastic member 423 presses the abutting column 422 toward the barrel opening, and the abutting column 422 is pressed on the barrel opening; when the bayonet 411 enters between the two second latches 42, the bayonet 411 squeezes the abutting column 422 to move away from the barrel opening, and the abutting elastic member 423 is squeezed to produce elastic deformation, and the abutting elastic member 423 has a movement tendency to push the abutting column 422 to move toward the barrel opening. When the bayonet 411 is installed in the locking position, the abutting elastic member 423 has a movement tendency to restore the original state, so the abutting column 422 is tightly pressed against the abutting surface 4111.

[0078] By providing the second latching member 42 , the latching process and the separation process of the first latching member 41 and the second latching member 42 are relatively simple, and the protective housing 100 can be quickly locked and unlocked, which is convenient for operation.

[0079] In some embodiments of the present invention, Figure 7 As shown, the abutment post 422 is a sphere.

[0080] The abutting column 422 is a sphere, which can reduce the friction between the abutting column 422 and the abutting surface 4111, is beneficial to the cooperation between the first buckle 41 and the second buckle 42, and can extend the service life of the buckle structure 4.

[0081] In some embodiments of the present invention, Figure 7 As shown, the elastic member 423 is a spring, which is arranged in the retaining tube 421 and can limit the deformation of the spring and improve the working reliability of the spring.

[0082] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the first cover body 1 and the second cover body 2 are connected via a hinge 5, and there are at least two hinges 5 distributed at intervals.

[0083] like Figure 1-Figure 3 As shown, taking the coordinates shown in the figure as a reference system, the lower ends of the first cover body 1 and the second cover body 2 are connected by a hinge 5, and the first cover body 1 and the second cover body 2 are opened and closed by the hinge 5 at the lower ends.

[0084] At least two hinges 5 are arranged at intervals, which can improve the structural stability of the protective housing 100, making the opening and closing process of the first cover 1 and the second cover 2 more stable and reducing shaking during the opening and closing process. Providing at least two hinges 5 can disperse the transmission of force, reduce the pressure on a single hinge 5, and thus extend the service life of the hinge 5.

[0085] In some embodiments of the present invention, Figure 8 As shown, the hinge 5 includes a first hinge 51 and a second hinge 52. There is one first hinge 51 and two second hinges 52, and the two second hinges 52 are arranged on both sides of the first hinge 51. By adopting a three-section hinge connection, the overall stability of the protective housing 100 can be improved.

[0086] The first hinge 51 is a double-hole connection hinge. The first hinge 51 is relatively long. The first hinge 51 and the first cover body 1 are connected through two mounting holes, and the first hinge 51 and the second cover body 2 are connected through two mounting holes. The first hinge 51 is a symmetrical structure, which improves the connection reliability and reduces the shaking during the opening and closing process. The second hinge 52 is a single-hole connection hinge. The second hinge 52 and the first cover body 1 are connected through one mounting hole, and the second hinge 52 and the second cover body 2 are connected through one mounting hole. The second hinge 52 is an asymmetrical structure. The two mounting holes on the second hinge 52 are spaced apart in the length direction of the first hinge 51, which is conducive to the lightweight design of the protective shell 100. In addition, the two second hinges 52 are symmetrically arranged with respect to the center line of the first hinge 51, which can make the process of the first cover body 1 and the second cover body 2 opening and closing each other more stable.

[0087] In some embodiments of the present invention, the first hinge 51 and the second hinge 52 are fixedly connected to the first cover body 1 and the second cover body 2 by means of an M5 bolt assembly.

[0088] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the size of the first cover body 1 in the left-right direction is greater than the size of the second cover body 2 in the left-right direction.

[0089] It is worth noting that the hydrogenation port of the hydrogenation module is located in the protective cavity 21, the second cover body 2 is fixed relative to the hydrogenation port, and the first cover body 1 can be opened and closed relative to the second cover body 2 to close or open the protective cavity 21.
