Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen generators, in particular to an anti-tipping device for a pure water portable hydrogen generator. Background Art

[0002] A pure water portable hydrogen generator is an advanced portable device specially designed to efficiently and safely produce high-purity hydrogen under on-site or mobile conditions. This device utilizes electrolyzed water technology and only requires adding deionized pure water as the raw material to work through a built-in zero-pole-distance pure water electrolytic cell. The core components of the electrolytic cell include an SPE solid electrolyte membrane and a noble metal current collector plate. The former serves as an ion conduction medium, and the latter promotes the uniform distribution of current, thereby improving the electrolysis efficiency.

[0003] In order to prevent the pure water portable hydrogen generator from tipping over, an anti-tipping mechanism is often provided on its side. When the existing anti-tipping mechanism is in use, there are the following deficiencies: In order to improve stability, the cross-sectional area of the support base provided at the bottom end of the leg is often increased. However, when the leg is retracted, the support base is still in the unfolded state, resulting in an increased occupied space and inconvenience for storage. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides an anti-tipping device for a pure water portable hydrogen generator, which has a simple structure. When the legs are retracted, the support base can be automatically folded, reducing the occupied space and improving the convenience of use.

[0005] An anti-tipping device for a pure water portable hydrogen generator of the utility model includes a hydrogen generator body, and anti-tipping mechanisms are provided on both sides of the hydrogen generator body; the anti-tipping mechanism includes a parallelogram link mechanism, and the output end of the parallelogram link mechanism is a leg, and the leg is vertically arranged;

[0006] The inside of the leg is hollow. Along the length direction of the leg, a slider slides in the leg. The bottom end of the leg is rotatably installed with a support base through a connecting shaft. One end of a driving rod is rotatably installed on the slider, and the other end of the driving rod is rotatably connected to the support base;

[0007] The device further includes a driving mechanism, which is used to drive the slider to slide when the leg moves.

[0008] As a preferred scheme of the utility model, the driving mechanism includes a rotating shaft rotatably installed on the leg. One end of a power rod is fixedly connected to the rotating shaft, and the other end of the power rod is slidably connected to the slider.

[0009] As a preferred embodiment of the present utility model, the driving mechanism further includes a first transmission wheel fixedly installed on the outer shell of the hydrogen generator body, and a second transmission wheel is arranged on the rotating shaft;

[0010] A transmission member is sleeved on the first transmission wheel and the second transmission wheel.

[0011] As a preferred embodiment of the present utility model, the outer diameter of the first transmission wheel is larger than the outer diameter of the second transmission wheel.

[0012] As a preferred embodiment of the present utility model, the parallelogram link mechanism includes two swing rods in a parallel state. One end of the two swing rods is rotatably connected to the outer shell of the hydrogen generator body, and the other end of the two swing rods is rotatably connected to the support leg.

[0013] As a preferred embodiment of the present utility model, one end of the swing rod is rotatably connected to the outer shell of the hydrogen generator body through bolts and nuts.

[0014] As a preferred embodiment of the present utility model, the support leg is provided with an opening for the driving rod to pass through.

[0015] As a preferred embodiment of the present utility model, the bottom of the support seat is provided with anti-slip patterns.

[0016] As a preferred embodiment of the present utility model, the slider is provided with a long hole, and a driving shaft is fixed at the other end of the power rod. The driving shaft is slidably connected to the long hole.

[0017] As a preferred embodiment of the present utility model, the surface of the support leg is chamfered.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the anti-tipping mechanism is in a working state and the support seat contacts the external support surface, when the hydrogen generator body has a tendency to tip over, the support seat is stressed to prevent the hydrogen generator body from tipping over. When it is necessary to store the support leg, hold the support leg to make the parallelogram link mechanism act. Under the action of the parallelogram link mechanism, the support leg moves upward and approaches the hydrogen generator body at the same time. When the support leg moves, the driving mechanism drives the slider to move upward. Since the bottom end of the support leg is rotatably installed with a support seat through a connecting shaft, and both ends of the driving rod are rotatably connected to the slider and the support seat respectively, the upward movement of the slider drives the support seat to rotate around the connecting shaft, so that the support seat automatically folds up, reducing the occupied space. Similarly, when the support leg moves in the reverse direction, the slider moves downward, causing the support seat to open, eliminating the need for manual operation of the opening and closing of the support seat and improving the convenience.

However, the present utility model can also be implemented in other ways different from those described herein.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0028] Embodiment 1

[0029] Referring to Figures 1-5 , this embodiment provides an anti-tipping device for a pure water portable hydrogen generator, which includes a hydrogen generator body 1. The hydrogen generator body 1 is a prior art and will not be elaborated herein. Anti-tipping mechanisms are provided on both sides of the hydrogen generator body 1. In order to improve stability, two groups of anti-tipping mechanisms are provided on each side; the anti-tipping mechanism includes a parallelogram link mechanism, and the output end of the parallelogram link mechanism is a leg 2, and the leg 2 is vertically arranged.

[0030] The inside of the outrigger 2 is hollow. Along the length direction of the outrigger 2, a slider 3 slides inside the outrigger 2. The bottom end of the outrigger 2 is rotatably installed with a support base 16 through a connecting shaft 4. In order to improve stability, two support bases 16 are provided. One end of a driving rod 5 is rotatably installed on the slider 3, and the other end of the driving rod 5 is rotatably connected to the support base 16;

[0031] It further includes a driving mechanism. When the outrigger 2 moves, the driving mechanism is used to drive the slider 3 to slide;

[0032] In this embodiment, during use, as Figure 1 and Figure 3 shown, the anti-tipping mechanism is in a working state, and the support base 16 is in contact with the external support surface. When the hydrogen generator body 1 has a tipping tendency, the support base 16 is stressed, playing a role in preventing the hydrogen generator body 1 from tipping. When it is necessary to store the outrigger 2, hold the outrigger 2 to make the parallelogram link mechanism act. Under the action of the parallelogram link mechanism, while the outrigger 2 moves upward, it approaches the hydrogen generator body 1. When the outrigger 2 moves, the driving mechanism drives the slider 3 to move upward. Since the bottom end of the outrigger 2 is rotatably installed with a support base 16 through a connecting shaft 4, and both ends of the driving rod 5 are rotatably connected to the slider 3 and the support base 16 respectively, the upward movement of the slider 3 drives the support base 16 to rotate around the connecting shaft 4, so that the support base 16 automatically folds up, reducing the occupied space. Similarly, when the outrigger 2 moves in the reverse direction, the slider 3 moves downward, causing the support base 16 to open, eliminating the need for manual operation of the opening and closing of the support base 16 and improving the convenience.

[0033] As a preferred solution of the present utility model, the driving mechanism includes a rotating shaft 6 rotatably installed on the outrigger 2 through a bearing seat. One end of the rotating shaft 6 is fixedly connected to a power rod 7, and the other end of the power rod 7 is slidably connected to the slider 3. More specifically, the slider 3 is provided with a long slot 14, and a driving shaft 15 is fixed to the other end of the power rod 7. The driving shaft 15 is slidably connected to the long slot 14; the driving mechanism further includes a first transmission wheel 8 fixedly installed on the outer shell of the hydrogen generator body 1, and a second transmission wheel 9 is arranged on the rotating shaft 6; a transmission member 10 is sleeved on the first transmission wheel 8 and the second transmission wheel 9; the outer diameter of the first transmission wheel 8 is larger than the outer diameter of the second transmission wheel 9; the first transmission wheel 8 and the second transmission wheel 9 can adopt synchronous belt wheels, and correspondingly, the transmission member 10 is a synchronous belt;

[0034] The parallelogram link mechanism includes two swing rods 11 in a parallel state. One end of the two swing rods 11 is rotatably connected to the outer shell of the hydrogen generator body 1, and the other end of the two swing rods 11 is rotatably connected to the outrigger 2; more specifically, the center connection line of the first transmission wheel 8 and the second transmission wheel 9 is parallel to the swing rod 11, and the center connection line of one end of the two swing rods 11 passes through the first transmission wheel 8, and the center connection line of the other end of the two swing rods 11 passes through the second transmission wheel 9;

[0035] In this embodiment, as Figure 3 and Figure 5 shown, when the support leg 2 is held and moved, under the action of the parallelogram linkage mechanism, the support leg 2 always maintains a vertical state. While the support leg 2 moves upward, it also moves towards the hydrogen generator body 1. Since the position of the first transmission wheel 8 is fixed, and the first transmission wheel 8 and the second transmission wheel 9 are sleeved with a transmission member 10, and the center connection line of the first transmission wheel 8 and the second transmission wheel 9 is parallel to the swing rod 11, and the center connection line of one ends of the two swing rods 11 passes through the first transmission wheel 8, and the center connection line of the other ends of the two swing rods 11 passes through the second transmission wheel 9, so during the movement of the support leg 2, the rotating shaft 6 rotates. Since the slider 3 is provided with a long hole 14, and a driving shaft 15 is fixed at the other end of the power rod 7, and the driving shaft 15 is slidably connected with the long hole 14, so that the slider 3 moves upward relative to the support leg 2. Since the bottom end of the support leg 2 is rotatably installed with a support seat 16 through a connecting shaft 4, and both ends of the driving rod 5 are rotatably connected with the slider 3 and the support seat 16 respectively, so when the slider 3 moves upward, it drives the support seat 16 to rotate around the connecting shaft 4, so that the support seat 16 automatically folds up.

[0036] As a preferred solution of the present utility model, one end of the swing rod 11 is rotatably connected to the outer shell of the hydrogen generator body 1 through bolts 12 and nuts 13. By such a setting method, after the nut 13 is tightened, the angle of the swing rod 11 can be fixed to prevent the support leg 2 from moving due to external force.

[0037] As a preferred solution of the present utility model, the support leg 2 is provided with an opening for the driving rod 5 to pass through to make space for the driving rod 5.

[0038] As a preferred solution of the present utility model, the bottom of the support seat 16 is provided with anti-slip lines to increase the friction with the external support surface.

[0039] As a preferred solution of the present utility model, the surface of the support leg 2 is chamfered to improve the comfort.

[0040] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing and production.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
