Description

Technical Field

[0001] The utility model relates to the field of hydrogen supply equipment, in particular to a bottle fixing structure, a hydrogen supply component and a vehicle. Background Art

[0002] Solid-state hydrogen storage is an important hydrogen storage technology, and hydrogen exchange is the main means of replenishing energy for small solid-state hydrogen storage devices. Therefore, the fixation of solid-state hydrogen storage bottles is a key technology for solid-state hydrogen exchange. At present, the fixation method of solid-state hydrogen storage bottles is usually to tighten the bottom of the solid-state hydrogen storage bottle or to screw the solid-state hydrogen storage bottle with a strap. The bottom tightening method has the problem of unreliable fixation, and the strap screw connection structure requires a large operating space and is cumbersome to operate. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a bottle fixing structure, a hydrogen supply assembly and a vehicle, wherein the bottle can be fixed reliably and the bottle can be easily replaced.

[0004] The first aspect of the utility model provides a bottle fixing structure, which includes: a bracket for supporting the bottle body; a pressing piece, which is arranged on the bracket, and a clamp for clamping the bottle body is formed between the pressing piece and the bracket; a first elastic piece, which is arranged between the pressing piece and the bracket, and applies an elastic force to the pressing piece to open the clamp; an adjusting component, which is pressed against the pressing piece to press the bottle body onto the bracket, and the pressing height of the adjusting component on the pressing piece is adjustable, so that the size of the clamp can be adjusted.

[0005] The bottle fixing structure provided in the embodiment of this aspect adopts a bracket to support the bottle, and uses a pressing piece to press the bottle onto the bracket, so that the bottle is fixed stably and reliably. Moreover, by changing the pressing height of the adjustment component on the pressing piece, the pressing piece can be pressed down on the bottle or away from the bottle, which is simple to operate, convenient to replace the bottle, and does not require a large operating space.

[0006] Specifically, when the bottle is not loaded, the adjustment component is at a relatively high depressed height on the pressing member, and the pressing member can expand the clamping opening under the elastic force of the first elastic member and maintain this posture, so that the bottle can be quickly placed in the larger clamping opening. When the bottle is fixed, the pressing member can be pushed to press the bottle by reducing the pressing height of the adjustment component on the pressing member, so that the clamping opening becomes smaller and clamps the bottle, and at this time, the first elastic member is compressed and contracted.

[0007] In addition, the bottle fixing structure provided in the above embodiment of the present application may also have the following additional technical features:

[0008] In some embodiments, the adjustment assembly includes: a pressure rod pressed against the pressing member; and a pressure rod adjustment unit connected to the pressure rod and used to adjust the pressing height of the pressure rod on the pressing member.

[0009] In these embodiments, the position of the pressure rod is adjusted by the pressure rod adjustment unit, and then the position of the pressing member is adjusted to achieve the fixing and release of the bottle body. The pressure rod is pressed against the pressing member, and the pressure rod has a certain length, which can stably press the pressing member down, so that the pressing member is stably kept in the state of pressing the bottle body, and the bottle body is reliably fixed.

[0010] In some embodiments, the pressure rod adjustment unit includes: a swing arm, the first end of the swing arm is installed and positioned through a first connecting shaft, and the second end of the swing arm is rotatably connected to the pressure rod through a second connecting shaft; a swing drive unit, the swing drive unit can drive the pressure rod to swing and make the swing arm rotate around the first connecting shaft.

[0011] In these embodiments, the pressure rod can swing under the drive of the swing drive unit, and the pressure rod can be moved up and down by the swing of the pressure rod, thereby changing the pressing height of the pressure rod on the pressing member. Compared with the straight up and down movement of the pressure rod, the movement trajectory of the pressure rod is limited by the swing arm, which is conducive to the pressure rod moving smoothly and accurately into position. Moreover, the pressure rod is rotatably connected to the swing arm and is not easy to fall.

[0012] In some embodiments, the swing driving portion abuts against one end of the pressure rod, and is used to apply a force to the pressure rod to move forward and backward in the extension direction of the pressure rod; the pressure rod adjustment unit also includes a second elastic member, one end of the second elastic member is connected to the pressure rod, and the other end is connected to the first end of the swing arm, and is used to apply a force to the pressure rod to make the pressure rod abut against the swing driving portion.

[0013] In these embodiments, the swing drive unit is located at one end of the pressure rod, and the pressure rod is swung by applying a force to the pressure rod to move forward and backward along its extension direction and cooperating with the swing arm. Compared with the swing drive unit directly pulling the pressure rod upward, the work done is smaller, the force is reduced, and the operation is convenient. Moreover, the swing drive unit is located at one end of the pressure rod, which does not increase the height of the bottle body fixing structure, and is convenient for placing the bottle body fixing structure in the vehicle. In addition, the second elastic member is used to apply a force to the pressure rod that is always in contact with the swing drive unit. On the one hand, it ensures that the movement of the swing drive unit can accurately drive the pressure rod to move, and on the other hand, it is conducive to the pressure rod to reset and move upward, so as to facilitate the expansion of the clamp to accommodate the bottle again.

[0014] In some embodiments, the swing driving part includes an eccentric wheel, which is installed and positioned by a third connecting shaft, and the eccentric wheel abuts against one end of the pressure rod. The rotation of the eccentric wheel drives the pressure rod to swing, thereby driving the swing arm to rotate. Here, the structural characteristics of the eccentric wheel are used to drive the pressure rod to swing, which has a simple structure and reliable driving.

[0015] In some embodiments, when the pressing member presses the bottle body, the eccentric wheel rotates in the first direction, and the maximum radius of the eccentric wheel gradually approaches the pressing rod to push the pressing rod to move away from the eccentric wheel and move downward, and then the eccentric wheel continues to rotate in the first direction to reach the pressing position. In the pressing position, the maximum radius of the eccentric wheel passes the center of the end face of the pressing rod to prevent the eccentric wheel from rotating in the opposite direction. This can effectively prevent the eccentric wheel from being easily moved to release the restriction on the pressing rod, resulting in unstable fixing of the bottle body.

[0016] In some embodiments, the swing driving unit further includes a handle, which is connected to the eccentric wheel, and the eccentric wheel is driven by the handle to rotate around the third connecting axis.

[0017] In these embodiments, the user holds the handle to rotate the eccentric wheel, thereby driving the pressure rod to move, which is easy to operate. Moreover, compared with using an electric method to drive the pressure rod to move, the swing drive part has a simple structure and low cost.

[0018] In some embodiments, the first end of the clamping member is rotatably connected to the bracket via a rotating shaft, and the first elastic member is disposed between the second end of the clamping member and the bracket. The clamping member can rotate around the rotating shaft under the pressure of the adjusting assembly to adjust the size of the clamp.

[0019] In these embodiments, the pressing member can rotate around the rotating axis to achieve pressing down and lifting of the pressing member. Compared with the straight up and down movement of the pressing member, there is no need to consider the problem of the pressing member falling off. The structure is simple, and the pressing member can move along the rotating path, which is conducive to accurately pressing down the bottle body.

[0020] In some embodiments, the bottle fixing structure also includes: a bottle mounting bin, the bracket is arranged on the bottom wall of the bottle mounting bin, and the adjustment assembly is arranged on the side wall of the bottle mounting bin; a bottle limiting frame is arranged in the bottle mounting bin, and the bottle limiting frame has a limiting hole for inserting the head of the bottle, and the inner wall of the limiting hole is adapted to the outer circumferential surface of the bottle body; the bottle mounting bin has a bottle loading and unloading port on one side close to the bottom of the bottle body, and the bracket is located on the side of the bottle limiting frame close to the bottle loading and unloading port, and the bottle can be placed in the bottle mounting bin through the bottle loading and unloading port.

[0021] In these embodiments, a bottle installation bin is provided for the bottle body, which is beneficial to protecting the bottle body and preventing dust and impurities from the outside from contaminating the bottle body. The bracket is arranged on the bottom wall of the bottle installation bin, which is beneficial to leveling the bottle body. The adjustment component is arranged on the side wall of the bottle installation bin, which is convenient for lateral adjustment of the height of the pressing member. A bottle limiting rack is also arranged in the bottle installation bin. When installing the bottle body, the bottle body is not only passed through the clamp, but also inserted into the limiting hole on the bottle limiting rack, which can further support and limit the bottle body and improve the installation stability of the bottle body. In addition, the bottle body is placed lying on the bracket and is put in or taken out through the bottle loading and unloading port, which is convenient to operate.

[0022] The second aspect of the present invention provides a hydrogen supply assembly, which includes: a bottle fixing structure as in any one of the above embodiments; a solid hydrogen storage bottle installed between a bracket and a clamping member; and a hydrogen supply pipeline connected to the outlet of the solid hydrogen storage bottle.

[0023] The hydrogen supply assembly provided in this embodiment has the bottle fixing structure of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here. Here, the solid hydrogen storage bottle is fixed in the bottle fixing structure, which is reliable and easy to disassemble and assemble.

[0024] A third aspect of the present invention provides a vehicle, comprising: a hydrogen supply component as described in the second aspect of the present invention.

[0025] The vehicle provided by this embodiment has the hydrogen supply assembly provided by the second embodiment, and thus has the beneficial effects of the second embodiment, which will not be described in detail here. In addition, the vehicle can use hydrogen for energy, saving energy.

[0060] The following will be combined Figures 1 to 9 The bottle fixing structure and hydrogen supply assembly provided in the embodiments of the utility model are introduced.

[0061] like Figure 1 and Figure 2 As shown, a first embodiment of the present invention provides a bottle fixing structure, which includes a bracket 110 , a pressing member 120 , a first elastic member 130 and an adjusting assembly 140 .

[0062] The bracket 110 is used to support the bottle body 200. The pressing member 120 is arranged on the bracket 110, and a clamping opening for clamping the bottle body 200 is formed between the pressing member 120 and the bracket 110. The first elastic member 130 is arranged between the pressing member 120 and the bracket 110, and applies elastic force to the pressing member 120 to open the clamping opening. The adjusting component 140 is pressed against the pressing member 120 to press the bottle body 200 against the bracket 110, and the pressing height of the adjusting component 140 on the pressing member 120 is adjustable, so that the size of the clamping opening can be adjusted.

[0063] The bottle fixing structure provided by the embodiment of this aspect adopts the bracket 110 to support the bottle 200, and uses the pressing member 120 to press the bottle 200 on the bracket 110, so that the bottle 200 is fixed stably and reliably. Moreover, by changing the pressing height of the adjustment component 140 on the pressing member 120, the pressing member 120 can be pressed down on the bottle 200 or away from the bottle 200, which is simple to operate, and the bottle 200 is easy to replace, and does not require a large operating space.

[0064] Specifically, when the bottle 200 is not loaded, the adjusting assembly 140 is at a relatively high depressed height on the pressing member 120, and the pressing member 120 can expand the clamping opening under the elastic force of the first elastic member 130 and maintain this posture, so that the bottle 200 can be quickly placed in the larger clamping opening. When the bottle 200 is fixed, the pressing member 120 can be pushed to press the bottle 200 by reducing the pressing height of the adjusting assembly 140 on the pressing member 120, so that the clamping opening becomes smaller and the bottle 200 is clamped. At this time, the first elastic member 130 is compressed and contracted.

[0065] In addition, the bottle fixing structure of this embodiment has good versatility. Even if the size of the bottle 200 becomes larger, as long as it can be loaded into the clamping opening and the clamping member 120 is pressed on the bracket 110, the bottle 200 can be fixed. It is not limited to the bottle 200 of one size.

[0066] To improve the fixing reliability of the bottle body 200, further, in some embodiments, as Figure 1 , Figure 2 and Figure 3 As shown, the bracket 110 supports the bottle body 200 from below, specifically supports the side wall of the bottle body 200, so that the bottle body 200 is placed flat on the bracket 110. Compared with the bottle body 200 being placed upright and the bracket 110 and the clamping member clamping the side wall of the bottle body 200, the probability of the bottle body 200 falling can be reduced.

[0067] Furthermore, the surface of the bracket 110 for fitting with the bottle body 200 can be designed as a curved surface, for example, the curved surface can be adapted to the outer surface of the bottle body 200. Of course, the curvature radius of the curved surface can also be made larger than the radius corresponding to the outer surface of the bottle body 200. When the bottle body 200 is placed on the curved surface, it will naturally move to the lowest point of the curved surface by its own gravity without rolling over a large range, making it convenient for the clamping member 120 to accurately press down the bottle body 200.

[0068] As an example, Figure 3 As shown, the upper surface of the bracket 110 has an arc-shaped supporting concave surface 111 , and the bottle body 200 can be placed flat on the arc-shaped supporting concave surface 111 .

[0069] Similarly, the surface of the pressing piece 120 for fitting with the bottle body 200 can also be designed to be a curved surface, which is the same as or similar to the curved surface on the above-mentioned bracket 110. If the pressing piece 120 can fully fit with the side wall of the bottle body 200 or press down the bottle body 200 at multiple points, the pressing effect on the bottle body 200 will be more stable, and the bottle body 200 can be stably clamped to prevent the bottle body 200 from moving.

[0070] As an example, Figure 3 As shown, the lower surface of the pressing member 120 has an arc-shaped pressing concave surface 121 , and the arc-shaped pressing concave surface 121 contacts the bottle body 200 .

[0071] In addition, in order to further improve the fit between the pressing member 120 and the bottle body 200, an elastic pad may be provided on the pressing member 120. When the elastic pad is in contact with the bottle body 200, the elastic pad is deformed under pressure during the pressing process of the pressing member 120, so that the bottle body 200 can be more fully fit and firmly clamped. Moreover, the design of the elastic pad is also conducive to reducing the friction between the pressing member 120 and the bottle body 200, and avoiding wear of the bottle body 200.

[0072] Based on the same reason, an elastic pad may be provided on the bracket 110 to support the bottle body 200 .

[0073] Regarding the connection between the pressing member 120 and the bracket 110 , further, in some embodiments, the pressing member 120 can move straight up and down relative to the bracket 110 under the adjustment of the adjustment assembly 140 .

[0074] For example, both ends of the bracket 110 have upright guide rods, the pressing member 120 can move up and down along the guide rods, and the first elastic member 130 is sleeved on the guide rods and supported between the pressing member 120 and the bracket 110 .

[0075] For another example, the bracket 110 has slots at both ends, the first elastic member 130 is disposed in the slots, and the pressing member 120 has support walls extending downward at both ends, which are inserted into the slots and supported by the first elastic member 130. The connection structure of the pressing member 120 and the bracket 110 is not limited to the above example.

[0076] In this case, the adjustment component 140 can be pressed against the upper middle area of ​​the clamping member 120, which is conducive to smoothly pressing down the clamping member 120. Of course, the adjustment component 140 can also press down one end of the clamping member 120 or both ends of the clamping member 120 at the same time.

[0077] Furthermore, in some other embodiments, Figure 1 , Figure 2 and Figure 3As shown, the first end of the pressing member 120 is rotatably connected to the bracket 110 , and the second end of the pressing member 120 can rotate relative to the bracket 110 under the adjustment of the adjustment assembly 140 .

[0078] For example, Figure 3 As shown, the first end of the clamping member 120 is rotatably connected to the bracket 110 via the rotating shaft 122, and the first elastic member 130 is arranged between the second end of the clamping member 120 and the bracket 110. The clamping member 120 can rotate around the rotating shaft 122 under the pressure of the adjusting assembly 140 to adjust the size of the clamp.

[0079] Here, the two ends of the first elastic member 130 can be connected to the second end of the pressing member 120 and the bracket 110 respectively. In a natural state, the second end of the pressing member 120 is tilted under the support of the first elastic member 130 to expand the clamping opening. At this time, the user can directly align the expanded clamping opening to put the bottle body 200. When the bottle body 200 needs to be compressed, the pressing member 120 rotates around the rotating shaft 122 under the pressure of the adjustment component 140, and the second end of the pressing member 120 compresses the first elastic member 130 and moves in the direction close to the bracket 110, narrowing the clamping opening, thereby compressing the bottle body 200. The two ends of the clamping piece 120 are respectively connected to the bracket 110 through the rotating shaft 122 and the first elastic piece 130, which can prevent the clamping piece 120 from being completely separated from the bracket 110. In addition, the movable range of the clamping piece 120 is limited by the first elastic piece 130 and the rotating shaft 122, and the clamping piece 120 will not flip outward too much, eliminating the user's operation of flipping the clamping piece 120 to cover the bottle body 200, and the bottle body 200 is easy to install.

[0080] For another example, the first end of the pressing member 120 is rotatably connected to the bracket 110 via the rotating shaft 122, one end of the first elastic member 130 is connected to the bracket 110 and is disposed close to the rotating shaft 122, the other end of the first elastic member 130 is connected to the middle of the pressing member 120, the first elastic member 130 is in a stretched state in a natural state, the pressing member 120 is pulled up to lift the second end of the pressing member 120, and the clamp is opened. The connection structure of the pressing member 120 and the bracket 110 is not limited to the above example.

[0081] In this case, the adjusting assembly 140 can directly press down the second end of the pressing member 120, or can also press down the middle of the pressing member 120. Figure 3As shown, a convex pressing portion 123 can be provided at the second end of the pressing member 120, so that the adjusting assembly 140 is pressed against the pressing portion 123. The design of the pressing portion 123 is convenient for cooperating with the adjusting assembly 140, and the adjusting assembly 140 presses down the pressing member 120 on one side, without occupying a large space above the pressing member 120, which is conducive to reducing the height of the bottle body fixing structure and conveniently placing it in the vehicle. Of course, it is also possible to have no pressing portion 123 and let the adjusting assembly 140 directly press down the pressing member 120.

[0082] The number of the bracket 110 can be one. In this case, the length of the bracket 110 is at least half the length of the bottle body 200, so as to facilitate stable support of the bottle body 200. In this case, the number of the pressing piece 120 can be one, which is also large in size, and at least presses half the length of the bottle body 200 to achieve stable downward pressure on the bottle body 200. Of course, the number of the pressing piece 120 can also be multiple, which are distributed at intervals along the length direction of the bracket 110, and press the bottle body 200 at multiple points to achieve stable installation of the bottle body 200.

[0083] The number of the brackets 110 can also be multiple, distributed at intervals along the length direction of the bottle body 200, supporting the bottle body 200 at multiple points, with good support stability, reduced materials, and cost savings. In this case, the number of the clamping members 120 can be the same as the number of the brackets 110 and connected one-to-one, and multiple groups of the same structure can clamp the bottle body 200, which is convenient for processing.

[0084] The clamping member 120 may be an arc-shaped arm structure or an arc-shaped plate structure, etc. The number of first elastic members 130 corresponding to each clamping member 120 may be one or more, as long as the clamping member 120 can open the clamping opening under the elastic force of the first elastic member 130 to allow the bottle 200 to be placed.

[0085] The number of the adjusting assembly 140 can be one, which presses against all the pressing members 120 at the same time and adjusts the position of the pressing members 120 at the same time, which is convenient and quick to operate.

[0086] As an example, Figure 1 and Figure 2 As shown, there are two brackets 110 , one pressing member 120 , the pressing member 120 is connected to the brackets 110 in a one-to-one correspondence, and there is one adjusting assembly 140 .

[0087] There may be multiple adjusting components 140 , each of which is pressed against at least one pressing member 120 . Thus, even if one of the adjusting components 140 causes the pressing member 120 to be lifted by mistake, the bottle body 200 can still be limited by other pressing members 120 , which provides good safety.

[0088] The adjustment component 140 can be an electric adjustment structure, which saves time and effort in operation. The adjustment component 140 can also be a manual adjustment structure, which saves energy and reduces costs.

[0089] Regarding the specific structure of the adjustment component 140, in some embodiments, as Figure 1 , Figure 2 and Figure 4 As shown, the adjustment assembly 140 includes a pressing plate and a pressing rod adjustment unit. The pressing rod 141 is pressed against the pressing member 120 . The pressing rod adjustment unit is connected to the pressing rod 141 and is used to adjust the pressing height of the pressing rod 141 on the pressing member 120 .

[0090] In these embodiments, the position of the pressing rod 141 is adjusted by the pressing rod adjustment unit, thereby adjusting the position of the pressing member 120 to achieve the fixing and releasing of the bottle body 200. The pressing rod 141 is pressed against the pressing member 120, and the pressing rod 141 has a certain length, which can stably press the pressing member 120, so that the pressing member 120 is stably maintained in the state of pressing the bottle body 200, and the bottle body 200 is reliably fixed.

[0091] As an example, Figure 1 As shown, the pressing rod 141 and the pressing member 120 are relatively vertically distributed and horizontally placed on the pressing member 120, that is, the pressing rod 141 is distributed parallel to the bottle body 200. In this way, no matter how many pressing members 120 are distributed in the length direction of the bottle body 200, as long as the pressing rod 141 is long enough, all the pressing members 120 can be pressed down. The pressing is performed by one pressing rod 141, and the structure is simple.

[0092] Of course, the adjustment component 140 is not limited to using the pressure rod 141 to press down the pressing member 120, and a wider pressure plate or other structure may also be used.

[0093] Regarding the specific structure of the pressure plate adjustment unit, in some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the pressure rod adjustment unit includes a swing arm 143 and a swing driving unit 145. The first end of the swing arm 143 is installed and positioned through a first connecting shaft 1431, and the second end of the swing arm 143 is rotatably connected to the pressure rod 141 through a second connecting shaft 1432. The swing driving unit 145 can drive the pressure rod 141 to swing and make the swing arm 143 rotate around the first connecting shaft 1431.

[0094] In these embodiments, the pressure rod 141 can swing under the drive of the swing driving part 145, and the pressure rod 141 can move up and down through the swing of the pressure rod 141, thereby changing the pressing height of the pressure rod 141 on the pressing member 120. Compared with the straight up and down movement of the pressure rod 141, the movement trajectory of the pressure rod 141 is limited by the swing arm 143, which is conducive to the pressure rod 141 to move smoothly and accurately into position. Moreover, the pressure rod 141 is rotatably connected to the swing arm 143 and is not easy to fall off.

[0095] Furthermore, in each pressure rod adjustment unit, there is one swing driving part 145 and a plurality of swing arms 143 , which are spaced apart along the length direction of the pressure rod 141 , which is conducive to the smooth swing of the pressure rod 141 .

[0096] As an example, Figure 4 As shown, there is one swing driving part 145 and two swing arms 143 , which are arranged near both ends of the pressure rod 141 .

[0097] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the swing driving part 145 is in contact with one end of the pressure rod 141, and is used to apply a force to the pressure rod 141 to move forward and backward in the extension direction of the pressure rod 141. The pressure rod adjustment unit also includes a second elastic member 144, one end of which is connected to the pressure rod 141, and the other end is connected to the first end of the swing arm 143, and is used to apply a force to the pressure rod 141 to make the pressure rod 141 abut against the swing driving part 145.

[0098] The swing drive unit 145 is located at one end of the pressure rod 141. By applying a force to the pressure rod 141 to move forward and backward along its extension direction and cooperating with the swing arm 143 to realize the swing of the pressure rod 141, compared with the swing drive unit 145 directly pulling the pressure rod 141 upward, the work done is smaller, the force is reduced, and the operation is convenient. Moreover, the swing drive unit 145 is located at one end of the pressure rod 141, which will not increase the height of the bottle body fixing structure, and it is convenient to place the bottle body fixing structure in the vehicle. In addition, the second elastic member 144 is used to apply a force to the pressure rod 141 that is always in contact with the swing drive unit 145. On the one hand, it ensures that the movement of the swing drive unit 145 can accurately drive the pressure rod 141 to move, and on the other hand, it is conducive to the pressure rod 141 to reset and move upward, so as to facilitate the clamp to accommodate the bottle body 200 again.

[0099] In a specific application, when the swing driving part 145 moves to the clamping position, the pressing rod 141 is pushed to move backward and downward, and the pressing rod 141 presses down the clamping member 120, pushing the clamping member 120 to press the bottle body 200. When the swing driving part 145 moves to the release position, the pressing rod 141 can move forward and upward under the elastic force of the second elastic member 144, and the clamping member 120 expands the clamping opening under the elastic force of the first elastic member 130, so that the user can take out the bottle body 200 conveniently.

[0100] Of course, in other examples, the other end of the second elastic member 144 can also be connected to other surrounding components, such as the side wall of the bottle body mounting bin 100, to directly apply an upward force to the pressure rod 141 to ensure that the pressure rod 141 can be reset.

[0101] The second elastic member 144 can be a spring, or a tension spring or a compression spring, as long as it can ultimately act on the pressure rod 141 to enable it to return to its original position and lift up.

[0102] Regarding the specific structure of the swing driving unit 145, in a specific embodiment, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the swing driving part 145 includes an eccentric wheel 1451, which is installed and positioned by a third connecting shaft 1453. The eccentric wheel 1451 abuts against one end of the pressure rod 141. The eccentric wheel 1451 rotates to drive the pressure rod 141 to swing, thereby driving the swing arm 143 to rotate. Here, the structural characteristics of the eccentric wheel 1451 are used to drive the pressure rod 141 to swing, which has a simple structure and reliable driving.

[0103] During the process of the pressing member 120 pressing the bottle body 200, the eccentric wheel 1451 rotates in the first direction, and the maximum radius of the eccentric wheel 1451 gradually approaches the pressing rod 141 to push the pressing rod 141 to move away from the eccentric wheel 1451 and move downward, and then the eccentric wheel 1451 continues to rotate in the first direction to reach the pressing position. In the pressing position, the maximum radius of the eccentric wheel 1451 passes the center of the end face of the pressing rod 141 to prevent the eccentric wheel 1451 from rotating in the opposite direction. It can effectively prevent the eccentric wheel 1451 from being easily moved to release the restriction on the pressing rod 141, resulting in unstable fixing of the bottle body 200. The first direction can be clockwise or counterclockwise.

[0104] It should be noted that even if the maximum radius of the eccentric wheel 1451 exceeds the center of the end face of the pressing rod 141, the eccentric wheel 1451 can still press the pressing member 120 into place via the pressing rod 141. Compared with the pressing rod 141 being pushed at the maximum radius of the eccentric wheel 1451 and the pressing member 120 being at the lowest position, although the pressing member 120 is slightly raised in theory, it can still fully press the bottle body 200 and will not cause the bottle body 200 to loosen.

[0105] The swing driving unit 145 may further include a handle 1452, which is connected to the eccentric wheel 1451, and the eccentric wheel 1451 is driven to rotate around the third connecting shaft 1453 by the handle 1452. The user holds the handle 1452 to rotate the eccentric wheel 1451, thereby driving the pressure rod 141 to move, which is easy to operate. Moreover, compared with driving the pressure rod 141 to move by electric means, the swing driving unit 145 has a simple structure and low cost.

[0106] As an example, Figure 5 As shown, in the process of pressing the bottle body 200, the user controls the handle 1452 to rotate clockwise, so that the handle 1452 rotates from the bottom of the eccentric wheel 1451 to the top. Figure 5 The two intersections of the middle dotted line and the outer contour of the eccentric wheel 1451 respectively represent the maximum radius and the minimum radius of the eccentric wheel 1451. When the handle 1452 is rotated approximately 180°, the maximum radius of the eccentric wheel 1451 is directly opposite to the pressure rod 141, pushing the pressure rod 141 to swing downward and backward. At this time, the pressure rod 141 can press down the clamping member 120 to squeeze the bottle body 200. Then, the handle 1452 is rotated a certain angle to make the maximum radius of the eccentric wheel 1451 pass over the pressure rod 141 and then stop, completing the downward pressure on the bottle body 200. At this time, if the eccentric wheel 1451 is accidentally touched to rotate counterclockwise, it is difficult for the maximum radius of the eccentric wheel 1451 to pass over the pressure rod 141 due to the restrictions of the maximum radius of the eccentric wheel 1451 and the pressure rod 141. If the bottle body 200 needs to be taken out, the user needs to apply a greater force to the handle 1452 to overcome the limitation of the maximum radius of the eccentric wheel 1451 and the pressure rod 141, thereby improving the fixing security of the bottle body 200.

[0107] In addition, the pressure rod adjustment unit may further include a position limiting locking member (not shown in the figure), which is used to limit the handle 1452 when the pressing member 120 presses the bottle body 200 onto the bracket 110. This can prevent the handle 1452 from rotating by mistake and causing the bottle body 200 to loosen.

[0108] For example, the limiting locking member is a convex rib. When the handle 1452 is rotated, it passes over the convex rib to reach the pressing position of the handle 1452. At this time, the convex rib can limit the handle 1452 from rotating in the opposite direction.

[0109] For another example, the limit locking member is a retractable limit portion, and when the handle 1452 is rotated, the handle 1452 first squeezes the retractable limit portion to retract, and when the handle 1452 is rotated to its pressing position, the pressing member 120 presses the bottle body 200, and the retractable limit portion automatically extends to limit the reverse rotation of the handle 1452. The specific structure of the limit locking member is not limited to the above example.

[0110] In another specific embodiment, the swing driving unit 145 does not include the eccentric wheel 1451, but includes a telescopic rod (not shown in the figure), the end of the telescopic rod has a telescopic head, and the telescopic head is extended to directly push the pressure rod 141 to swing.

[0111] For example, the swing driving part 145 includes a handle and a retractable push rod, the push rod abuts against one end of the pressure rod 141, and the handle can drive the push rod to extend and retract, thereby applying a force to the pressure rod 141 to move forward and backward in the extension direction of the pressure rod 141.

[0112] Alternatively, the swing driving unit 145 is an electric structure, and does not require manual operation by the user. For example, the swing driving unit 145 is a hydraulic rod (not shown in the figure) or an electric telescopic rod (not shown in the figure).

[0113] In other embodiments, the swing driving part 145 does not abut against one end of the pressure rod 141, but abuts against the top of the pressure rod 141. In this case, the eccentric wheel 1451 can be rotatably arranged above the pressure rod 141, and the eccentric wheel 1451 abuts against the pressure rod 141, and is used to apply a force to the pressure rod 141 to move forward and backward in the extension direction of the pressure rod 141. In this case, the pressure rod adjustment unit also includes a reset elastic member, which is connected to the pressure rod 141 and is used to apply a pulling force or a squeezing force to the pressure rod 141 toward the eccentric wheel 1451. Ensure that the pressure rod 141 can be reset.

[0114] In this case, the eccentric wheel 1451 can be located above one end of the pressure rod 141 . Of course, the eccentric wheel 1451 can also be located above the middle part of the pressure rod 141 .

[0115] In other embodiments, the swing driving part 145 is not in contact with one end of the pressing rod 141, but is directly connected to one end of the pressing rod 141 to apply a force to the pressing rod 141 to move forward and backward in the extension direction of the pressing rod 141. It is ensured that the swing driving part 145 drives the pressing rod 141 to move.

[0116] For example, the pressure rod 141 is directly extended and a handle is provided thereon (not shown in the figure), a socket is provided on the pressure rod 141 or the handle (not shown in the figure), and the swing driving part 145 further includes a limiting convex rib (not shown in the figure) located on one side of the pressure rod 141. When the pressure rod 141 moves downward and backward to the pressing position, the limiting convex rib is inserted into the socket to fix the bottle body 200. Of course, the specific structure of the swing driving part 145 is not limited to the above example.

[0117] Regarding the specific structure of the adjustment component 140, in some embodiments, the adjustment component 140 includes an adjustment frame (not shown in the figure) and an adjustment rod (not shown in the figure), a portion of the adjustment frame is horizontally placed in the upper middle area of ​​the clamping member 120, and the adjustment rod is erected on the portion of the adjustment frame located above the clamping member 120, and the adjustment rod can move up and down along the adjustment frame, thereby pressing the clamping member 120 downward.

[0118] Or in some embodiments, the adjustment component 140 is disposed on one side of the bracket 110 and has an adjustment rod (not shown in the figure) that moves in a seesaw manner, and one end of the adjustment rod moves downward to press the upper middle area of ​​the clamping member 120.

[0119] The specific structure and setting position of the adjustment component 140 can be various, not limited to the above examples, as long as it can be pressed against the pressing member 120 to press the bottle body 200 onto the bracket 110.

[0120] Furthermore, in some embodiments, Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the bottle fixing structure further includes a bottle mounting bin 100, and a bracket 110 is arranged on the bottom wall of the bottle mounting bin 100. Here, the bottle mounting bin 100 is arranged for the bottle 200, which is beneficial to protecting the bottle 200 and preventing the external dust and impurities from contaminating the bottle 200. The bracket 110 is arranged on the bottom wall of the bottle mounting bin 100, which is beneficial to laying the bottle 200 flat.

[0121] Furthermore, if Figure 8 As shown, the adjustment assembly 140 is disposed on the side wall of the bottle installation bin 100 , so as to facilitate the lateral adjustment of the height of the pressing member 120 without increasing the height of the bottle installation bin 100 .

[0122] As an example, Figure 4 and Figure 8 As shown, a swing arm fixing seat 142 is provided on the side wall of the bottle installation bin 100, and the first end of the swing arm 143 of the adjustment assembly 140 is connected to the swing arm fixing seat 142 through a first connecting shaft 1431. The eccentric wheel 1451 is installed on the side wall of the bottle installation bin 100 through a third connecting shaft 1453.

[0123] Of course, the adjustment component 140 may also be disposed on the bottom wall of the bottle mounting bin 100 or at other locations, depending on the specific structure of the adjustment component 140 .

[0124] Furthermore, if Figure 8 and Fig. 9As shown, the bottle fixing structure also includes a bottle limiting frame 150, which is arranged in the bottle installation bin 100. The bottle limiting frame 150 has a limiting hole 151 for the head of the bottle 200 to be inserted, and the inner wall of the limiting hole 151 is adapted to the outer peripheral surface of the bottle 200. When installing the bottle 200, the bottle 200 is inserted into the limiting hole 151 on the bottle limiting frame 150 in addition to passing through the clamp, so that the bottle 200 can be further supported and limited, thereby improving the installation stability of the bottle 200.

[0125] Furthermore, if Figure 7 , Figure 8 and Fig. 9 As shown, the bottle installation bin 100 has a bottle loading and unloading port 101 on one side close to the bottom of the bottle 200, and the bracket 110 is located on the side of the bottle limiting frame 150 close to the bottle loading and unloading port 101, so that the bottle 200 can be placed in the bottle installation bin 100 through the bottle loading and unloading port 101. The bottle 200 is placed lying on the bracket 110 and is placed in or taken out through the bottle loading and unloading port 101, which is convenient for operation. At this time, if the adjustment component 140 is arranged on the side wall of the bottle installation bin 100, it is convenient for users to operate the adjustment component 140.
