Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a bracket structure and a movable device component. Background Art

[0002] In the related art, the movable device assembly includes a bracket structure and an electronic device. The bracket structure includes a base and a support rod. The screen is supported on the support rod. In order to meet the user's functions such as meetings, watching TV series, learning and games, the electronic device is usually equipped with an extra-large screen. At this time, the center of gravity of the whole machine moves upward as the screen size increases. When the user touches the screen too hard, the movable device assembly is at risk of tipping over. If the base is widened, the whole machine will occupy a large area and its flexibility will be reduced. Summary of the Invention

[0003] The present application aims to provide a support structure and a movable device assembly, which at least solve the problem that the support structure is prone to tipping over.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes a bracket structure, including: a base, the base is provided with a first cavity, and a liquid medium is provided in the first cavity; a support assembly is provided on the base, the support assembly includes a support rod and a lifting rod which are mutually sleeved, the support rod is fixedly connected to the base, and the lifting rod is slidably connected to the support rod; a support plate is provided at an end of the lifting rod away from the base, and the support plate is used to place electronic equipment; wherein, a second cavity and a connecting area are provided in the support rod, at least a part of the connecting area is located in the first cavity, and the connecting area is provided with a first connecting port, the second cavity is connected to the first cavity through the first connecting port, a third cavity is formed between the lifting rod and the support rod, a second connecting port is provided at the bottom of the third cavity, and the third cavity is connected to the first cavity through the second connecting port; when the lifting rod is lowered relative to the base, the liquid medium flows from the first cavity to the second cavity; when the lifting rod is raised relative to the base, the liquid medium flows from the second cavity to the first cavity.

[0006] In a second aspect, an embodiment of the present application proposes a movable device assembly, comprising: an electronic device; and a bracket structure as described in any one of the first aspects, wherein the electronic device is supported on a supporting plate.

[0007] In an embodiment of the present application, the support structure includes a base, a support assembly and a support plate. The support assembly includes a support rod and a lifting rod that are sleeved with each other. The support rod is fixed to the base, and the support plate is provided at one end of the lifting rod away from the base. The lifting rod can slide relative to the support rod to adjust the support height of the electronic device by lifting and lowering the lifting rod. The base is provided with a first cavity, the support rod is provided with a second cavity and a connecting area that are interconnected, and a third cavity is enclosed between the lifting rod and the support rod. The second cavity is connected to the first cavity through a first connecting port on the connecting area, and the third cavity is connected to the first cavity through a second connecting port at the bottom. In this way, when the lifting rod is lowered relative to the base, the length of the lifting rod extending into the support rod increases, so that the volume of the third cavity below the lifting rod decreases. Since the third cavity is connected to the first cavity through the second connecting port, the volume of the third cavity and the first cavity as a whole is reduced, thereby increasing the gas pressure in the first cavity, so that the first cavity is lowered. The liquid medium in the cavity flows to the second cavity, thereby raising the center of gravity of the entire support structure; when the lifting rod is raised relative to the base, the length of the lifting rod extending out of the support rod increases and the length located inside the support rod decreases, thereby increasing the volume of the third cavity below the lifting rod. Since the third cavity is connected to the first cavity through the second connecting port, the overall volume of the first cavity and the third cavity increases, thereby reducing the gas pressure in the first cavity and the pressure acting on the bottom of the liquid medium, causing the liquid medium to flow to the first cavity, thereby lowering the center of gravity of the entire support structure, preventing the support structure from tipping over, and improving the safety performance of the support structure.

[0030] The following combination Figures 1-14 The support structure and movable device assembly according to the embodiments of the present application are described.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 11As shown, the bracket structure according to the embodiment of the present application includes: a base 1, the base 1 is provided with a first cavity 10, and a liquid medium 5 is provided in the first cavity 10; a support assembly 4, which is provided on the base 1, and the support assembly 4 includes a support rod 2 and a lifting rod 3 which are sleeved on each other, the support rod 2 is fixedly connected to the base 1, and the lifting rod 3 is slidably connected to the support rod 2; a supporting plate 7, which is provided at one end of the lifting rod 3 away from the base 1, and the supporting plate 7 is used to place an electronic device 6; wherein, a second cavity 22 and a communication area 24 which are connected to each other are provided in the support rod 2, and at least a part of the communication area 24 is located at Inside the first cavity 10, a first communicating port 240 is provided in the communicating area 24, the second cavity 22 is communicated with the first cavity 10 through the first communicating port 240, a third cavity 29 is formed between the lifting rod 3 and the support rod 2, a second communicating port 200 is provided at the bottom of the third cavity 29, and the third cavity 29 is communicated with the first cavity 10 through the second communicating port 200; when the lifting rod 3 is lowered relative to the base 1, the liquid medium 5 flows from the first cavity 10 to the second cavity 22; when the lifting rod 3 is raised relative to the base 1, the liquid medium 5 flows from the second cavity 22 to the first cavity 10.

[0032] In an embodiment of the present application, the bracket structure includes a base 1, a support assembly 4 and a support plate 7. The support assembly 4 includes a support rod 2 and a lifting rod 3 that are arranged in a mutually nested manner. The support rod 2 is fixed to the base 1. The support plate 7 is arranged at one end of the lifting rod 3 away from the base 1, and the lifting rod 3 can slide relative to the support rod 2 to achieve adjustment of the support height of the electronic device 6 by raising and lowering the lifting rod 3. Among them, the base 1 is provided with a first cavity 10, the support rod 2 is provided with a second cavity 22 and a communication area 24 that are interconnected, and a third cavity 29 is enclosed between the lifting rod 3 and the support rod 2. The second cavity 22 is connected to the first cavity 10 through a first communication port 240 on the communication area 24, and the third cavity 29 is connected to the first cavity 10 through a second communication port 200 at the bottom. In this way, when the lifting rod 3 is lowered relative to the base 1, the length of the lifting rod 3 extending into the support rod 2 increases, so that the volume of the third cavity 29 below the lifting rod 3 is reduced. Since the third cavity 29 is connected to the first cavity 10 through the second communication port 200, the overall volume of the third cavity 29 and the first cavity 10 is reduced, thereby making the gas in the first cavity 10 The pressure increases, causing the liquid medium 5 in the first cavity 10 to flow to the second cavity 22, thereby raising the center of gravity of the entire support structure; when the lifting rod 3 rises relative to the base 1, the length of the lifting rod 3 extending out of the support rod 2 increases, and the length located inside the support rod 2 decreases, thereby increasing the volume of the third cavity 29 below the lifting rod 3. Since the third cavity 29 is connected to the first cavity 10 through the second connecting port 200, the overall volume of the first cavity 10 and the third cavity 29 increases, thereby reducing the gas pressure in the first cavity 10 and the pressure acting on the bottom of the liquid medium 5, thereby reducing the liquid medium 5 to flow to the first cavity 10, thereby lowering the center of gravity of the entire support structure, thereby preventing the support structure from tipping over and improving the safety performance of the support structure.

[0033] The bracket structure proposed in this application improves the anti-tilting ability of the entire machine while keeping the weight and bottom area of the base 1 unchanged, or can make the base 1 lighter and smaller while maintaining the same anti-tilting ability, thereby improving the flexibility of the entire machine.

[0034] It can be understood that the first cavity 10 and the third cavity 29 constitute a sealed cavity.

[0035] It is understandable that at least a portion of the communication area 24 extends into the first cavity 10 , so that the communication area 24 is always filled with liquid medium, thereby preventing the sealed cavity formed by the first cavity 10 and the third cavity 29 from communicating with the second cavity 22 .

[0036] It can be understood that when the lifting rod 3 rises, the lifting rod 3 moves away from the base 1 along the length direction, and when the lifting rod 3 falls, the lifting rod 3 moves toward the base 1 along the length direction.

[0037] like Figure 2 、 Figure 6 、 Figure 9 and Figure 14 As shown, according to some embodiments of the present application, optionally, at least a portion of the side wall of the communication area 24 is an inclined surface, and along the lifting direction of the lifting rod 3, the inclined surface is inclined toward the interior of the communication area 24 from the end away from the first communication port 240 to the end where the first communication port 240 is provided.

[0038] In this embodiment, at least a portion of the sidewall of the communication region 24 is an inclined surface, so that the cross-sectional area of the communication region 24 gradually changes from bottom to top. When the support structure is raised or lowered, the liquid medium 5 flows into the first cavity 10 through the first communication port 240. The change in cross-sectional area constrains the flow rate and flow rate, resulting in more gradual and orderly changes. This prevents the liquid medium 5 from suddenly and massively flowing into the first cavity 10, causing excessive center of gravity adjustment or violent shaking, thereby improving the dynamic stability of the support structure during center of gravity adjustment. At the same time, when the lifting rod 3 switches between rising and lowering, the liquid medium 5 flows through the communication region 24. Because the communication region 24 is wide at the top and narrow at the bottom, the force below the communication region 24 is greater, making it easier to break the equilibrium state, thereby allowing the liquid to flow smoothly between the first cavity 10 and the second cavity 22.

[0039] According to some embodiments of the present application, optionally, at least a portion of the inclined surface has an arc-shaped structure.

[0040] In this embodiment, at least a portion of the inclined surface is in an arc-shaped structure, which can make the flow of the liquid smoother when the position of the lifting rod 3 changes.

[0041] like Figure 2 、 Figure 6 、 Figure 9 and Figure 14 As shown, according to some embodiments of the present application, optionally, the first communication port 240 is provided at the bottom of the communication area 24 ; and / or the first communication port 240 is located on a side of the communication area 24 away from the second communication port 200 .

[0042] In this embodiment, the first connecting port 240 is located at the bottom of the connecting area 24, which can ensure that the first connecting port 240 is always immersed in the liquid medium 5, so that the sealed cavity formed by the first cavity 10 and the third cavity 29 cannot be connected to the second cavity 22. Then, when the lifting rod 3 is raised and lowered to change the volume of the third cavity 29, the liquid medium 5 can be driven to ensure the reliability of the change of the center of gravity of the bracket structure. Optionally, the first connecting port 240 is located on the side of the connecting area 24 away from the second connecting port 200. On the one hand, such a setting can make the first connecting port 240 face the outside of the supporting assembly 4 as a whole, which is convenient for the processing and manufacturing of the first connecting port 240. On the other hand, when the lifting rod 3 rises, the volume of the third cavity 29 increases, and the gas in the first cavity 10 flows to the third cavity 29 through the second connecting port 200, so that negative pressure is generated at the second connecting port 200. Setting the first connecting port 240 away from the second connecting port 200 can prevent the liquid medium 5 at the first connecting port 240 from being sucked into the second connecting port 200 by the negative pressure, thereby ensuring the reliability of the center of gravity adjustment.

[0043] like Figure 4 、 Figure 5 and Figure 7 As shown, according to some embodiments of the present application, optionally, the support rod 2 includes: a rod body portion 26, which is arranged on the top wall of the base 1, the rod body portion 26 includes a sleeve cavity 20 and a second cavity 22, the second cavity 22 is arranged around the sleeve cavity 20, the lifting rod 3 is arranged in the sleeve cavity 20, and the bottom of the lifting rod 3 and the side wall of the sleeve cavity 20 enclose a third cavity 29; at least one connecting section 28 is arranged at the bottom of the rod body portion 26, the connecting area 24 is arranged in the connecting section 28, and at least a portion of the connecting section 28 is arranged in the first cavity 10.

[0044] In this embodiment, the support rod 2 includes a rod body 26 and at least one connecting section 28. The rod body 26 includes a sleeve cavity 20 and a second cavity 22. The lifting rod 3 is disposed in the sleeve cavity 20 and is capable of sliding in the sleeve cavity 20 to achieve the lifting and lowering of the lifting rod 3. The rod body 26 is located on the top wall of the base 1, so that the sleeve cavity 20 and the second cavity 22 are both located on the top wall of the base 1. In this way, after the liquid medium 5 flows from the second cavity 22 to the first cavity 10, the center of gravity of the entire support structure can be lowered. The second cavity 22 is arranged around the circumference of the sleeve cavity 20, structurally ensuring the uniform distribution of the liquid medium 5 around the periphery of the sleeve cavity 20, bringing stability and balanced center of gravity adjustment to the support structure. The annular cavity allows the liquid medium 5 to be synchronously filled or refluxed circumferentially around the sleeve cavity 20 as it flows along the lifting rod 3, thus avoiding the problem of center of gravity offset caused by unilateral liquid accumulation. In particular, when the support structure is subjected to multi-angle rotation, tilt adjustment, and other operations, the circumferential uniform distribution of the liquid medium 5 can form a symmetrical counterweight effect, effectively offsetting the lateral torque generated by the deflection of the equipment, and improving the support structure's ability to resist tilting in complex postures. In addition, the connecting section 28 is provided at the bottom of the rod body 26, and the connecting area 24 is provided on the connecting section 28, so that the second cavity 22 is connected to the first cavity 10 through the connecting area 24, while also ensuring the reliability of the connection between the support assembly 4 and the base 1.

[0045] It should be noted that the lifting rod 3 is disposed within the sleeve cavity 20, and the bottom of the lifting rod 3 and the inner wall of the sleeve cavity 20 enclose a third cavity 29. In other words, the third cavity 29 constitutes at least a portion of the sleeve cavity 20. When the bottom of the lifting rod 3 contacts the bottom wall of the sleeve cavity 20, the volume of the third cavity 29 is zero. When the bottom of the lifting rod 3 is located at the top of the sleeve cavity 20, the volume of the third cavity 29 is equal to or less than the volume of the third cavity 29.

[0046] It can be understood that the second communication port 200 is provided on the bottom wall of the sleeve cavity 20 .

[0047] According to some embodiments of the present application, optionally, the communication section 28 is supported on the bottom wall of the first cavity 10 ; and / or when there are multiple communication sections 28 , the multiple communication sections 28 are arranged at circumferential intervals around the second communication port 200 .

[0048] In this embodiment, the connecting section 28 is supported on the bottom wall of the first cavity 10, thereby improving the connection stability between the support assembly 4 and the base 1. Optionally, if there are multiple connecting sections 28, the multiple connecting sections 28 are arranged at intervals around the circumference of the second connecting opening 200, thereby improving the connection stability between the support assembly 4 and the base 1 and preventing the support assembly 4 from tipping over due to different flow rates of the liquid medium 5 along the circumference of the second cavity 22.

[0049] Optionally, when the first connecting port 240 is provided at the bottom of the connecting area 24, one end of the connecting area 24 provided with the first connecting port 240 is directly supported on the bottom wall of the first cavity 10. On the one hand, it can enhance the connection strength between the support rod 2 and the base 1, and avoid the situation where the lifting rod 3 tips over or breaks when being raised or lowered. On the other hand, it can also ensure that the connecting area 24 is always filled with liquid medium 5 to ensure the sealing of the sealed cavity.

[0050] According to some embodiments of the present application, optionally, in a cross-section perpendicular to the lifting direction of the lifting rod 3, the cross-sectional area of the first cavity 10 is larger than the cross-sectional area of the second cavity 22; and / or along the lifting direction of the lifting rod 3, the height of the first cavity 10 is smaller than the height of the second cavity 22.

[0051] In this embodiment, the cross-sectional area of the first cavity 10 is larger than that of the second cavity 22, allowing the first cavity 10 to accommodate more liquid medium 5 in its working state. When the lifting rod 3 rises, the amount of liquid medium 5 flowing into the first cavity 10 increases, and the center of gravity drops by an amount that increases simultaneously with the adjustment sensitivity, effectively offsetting the overturning moment generated by the upper weight, maintaining stable support even at maximum height adjustment. Optionally, the height of the first cavity 10 is less than the height of the second cavity 22, making the first cavity 10 flat. When the liquid medium 5 flows into the first cavity 10, the liquid level of the liquid medium 5 is lower, thereby lowering the overall center of gravity of the support structure.

[0052] It should be noted that the cross section of the first cavity 10 is a cross section perpendicular to the lifting direction of the lifting rod 3 , and the cross section of the second cavity 22 is a cross section perpendicular to the lifting direction of the lifting rod 3 .

[0053] Optionally, the base 1 is a hollow cylinder, the support rod 2 is a hollow cylinder, wherein the sleeve cavity 20 is cylindrical. Of course, the shape of the base 1 and the support rod 2 can also be a cuboid, a cube, a cone or an irregular shape, etc.

[0054] like Figure 4 and Figure 9 As shown, according to some embodiments of the present application, optionally, a through hole 220 is provided at one end of the second cavity 22 away from the base 1 , and the through hole 220 is connected to the external environment.

[0055] In this embodiment, during the process of the liquid medium 5 flowing driven by the lifting rod 3, the through hole 220 on the second cavity 22 can control the inlet and outlet paths of external air. When the liquid medium 5 flows toward the first cavity 10, the space above the second cavity 22 forms a negative pressure due to the reduction of liquid. The through hole 220 promptly introduces external air to prevent the vacuum effect from hindering the flow of the liquid medium 5, ensuring the smoothness of the center of gravity adjustment process. When the liquid medium 5 flows back to the second cavity 22, the through hole 220 can quickly discharge excess air inside the cavity, preventing the accumulation of air pressure from affecting the liquid filling efficiency. This dynamic air pressure balance design ensures that the flow of the liquid medium 5 is completely driven by the displacement of the lifting rod 3. Among them, the through hole 220 is located at the end of the second cavity 22 away from the base 1, so that the through hole 220 is far away from the first cavity 10. On the one hand, it can prevent the liquid medium 5 from flowing out of the through hole 220, and on the other hand, it can prevent the through hole 220 from connecting with the first cavity 10, ensuring the reliability of the liquid medium 5 moving with the lifting rod 3.

[0056] According to some embodiments of the present application, optionally, the supporting plate 7 is rotatably connected to the lifting rod 3 .

[0057] In this embodiment, the supporting plate 7 is rotatably connected to the lifting rod 3, so that the supporting angle of the electronic device 6 can be adjusted, thereby improving the convenience of use.

[0058] Optionally, the lifting rod 3 and the supporting plate 7 are connected via a universal wheel. Alternatively, the lifting rod 3 and the supporting plate 7 are rotatably connected via a rotating shaft.

[0059] like Figure 13 and Figure 14 As shown, according to one embodiment of the present application, a movable device assembly is provided, comprising: an electronic device 6; and a support structure as described above, wherein the electronic device 6 is supported on a support plate 7. Because the electronic device 6 includes any of the support structures described above, it has all the benefits of the support structure, which will not be further described here.

[0060] Optionally, the mobile device component includes an all-in-one tablet conference device.

[0061] Optionally, universal wheels are provided at the bottom of the base 1. The electronic device 6 includes a flat panel or a television.

[0062] According to some embodiments of the present application, the present application optionally provides a mobile tablet support structure (e.g., a support structure) that adjusts the center of gravity of the entire device by changing the weight distribution of the entire device. Specifically, the present application is designed to have a structure containing multiple cavities containing liquid (e.g., liquid medium 5), and the lifting rod 3 is designed to be liftable.

[0063] like Figure 9 and Figure 10As shown, in the initial state, the entire machine is in an unused state, and liquid exists in the narrow cavity at the top (such as the second cavity 22); when it is switched from the unused state to the working state, the liquid in the narrow cavity at the top is pushed into the wide cavity at the bottom (such as the first cavity 10) under the action of the pressure difference. At this time, the center of gravity of the base 1 is lowered, thereby increasing the stability of the entire machine and improving the anti-tilting ability of the entire machine.

[0064] This application improves the anti-tilting ability of the entire device while keeping the weight and bottom area of the base 1 unchanged, or, while maintaining the same anti-tilting ability, can make the base 1 lighter and smaller, thereby improving the flexibility of the entire device. This application can reduce users' concerns about the entire device tipping over when using the product.

[0065] like Figure 13 and Figure 14 As shown, a tablet (e.g., electronic device 6) is placed on the support structure, and the tablet is supported by the lifting rod 3. The lifting rod 3 cooperates with the sleeve feature (e.g., sleeve cavity 20) in the middle of the support rod 2 and can move up and down in the sleeve cavity 20.

[0066] A cavity (such as the second cavity 22) is designed on the outside of the sleeve, which has a narrower cross-sectional area and a higher position relative to the cavity of the base 1. In the initial state, the narrower and higher cavity (such as the second cavity 22) contains liquid, and the wider and lower cavity of the base 1 (such as the first cavity 10) is free of liquid. The two chambers are connected through an arc area (such as the connecting area 24) at the bottom of the support rod 2, which is wider at the top and narrower at the bottom. When the support structure switches to the working state or returns to the initial state, the lifting rod 3 rises or falls, which will cause an imbalance in the pressure in the two cavities. Under the action of the pressure difference, the liquid between the two cavities flows between the two cavities through the arc area, thereby completing the distribution adjustment of the center of gravity of the whole machine. The present application is designed with two parts: the second cavity 22 and the sealed cavity (such as the whole after the third cavity 29 and the first cavity 10 are connected through the second connecting port 200).

[0067] Alternatively, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the support rod 2 is a cylindrical structure with a sleeve-like feature in the middle. The lifting rod 3 cooperates with the support rod 2, and a cavity (e.g., second cavity 22) is designed between the outer wall of the support rod 2 and the sleeve cavity 20. A vent (e.g., through-hole 220) is designed at the top of the second cavity 22 to keep the air pressure in the second cavity 22 the same as the atmospheric pressure.

[0068] Base 1 is a cylindrical structure with a larger cross-section than support rod 2, but shorter in height. Support rod 2 is mounted above base 1, with its sleeve cavity 20 communicating with first cavity 10 of base 1. Lifting rod 3, sleeve cavity 20, and first cavity 10 form a sealed chamber. The bottom cross-section of the sealed chamber is larger than that of second cavity 22, but its height is smaller.

[0069] The second cavity 22 and the sealed cavity are connected via a circular arc at the bottom of the support rod 2. Liquid flows between the two chambers through this arc. The arc is designed to be wide at the top and narrow at the bottom, forming a circular arc. The arc connecting area 24 is designed to contain liquid and maintain this area at all times to ensure the sealing of the sealed cavity.

[0070] The implementation process is divided into three phases: initial phase, working phase, and recovery phase.

[0071] Initial stage:

[0072] like Figure 8 、 Figure 9 and Figure 10 As shown, in the initial state, liquid exists in the second cavity 22 and the arc area, the sealing cavity is free of liquid, and the lifting rod 3 is located at the bottom of the sleeve cavity 20. At this time, the pressure in the second cavity 22 is P1=P1 气 +ρgh1,P1 气 is the air pressure of the second cavity 22, ρ is the liquid density, g is the acceleration due to gravity, and h1 is the height of the liquid in the second cavity 22. The pressure in the sealed cavity P2=P2 气 +ρgh2,P2 气 is the air pressure in the sealed chamber, and h2 is the height of the liquid in the sealed chamber.

[0073] In the initial state, the device is in a stable state, at which point P1 = P2, i.e. P1 气 +ρgh1=P2 气 +ρgh2.

[0074] Working stage:

[0075] like Figure 11 and Figure 12 As shown, at the beginning of the working phase, the bracket is lifted and the lifting rod 3 is pulled up from the sleeve cavity 20 (along Figure 12 In the direction indicated by the arrow in the middle), the volume of the sealed cavity increases, resulting in P2 气 Due to the presence of the vent hole, the air pressure P1 in the second cavity 22 气 The same as atmospheric pressure and remains constant. 气It decreases, and the pressure balance between the second cavity 22 and the sealing cavity is broken (P1 > P2). According to the principle of hydrostatic equilibrium (P1 = P2), to re - achieve the pressure balance state between the two cavities, the height h1 of the liquid in the second cavity 22 will decrease, and the height h2 of the liquid in the sealing cavity will increase. The liquid flows through the arc area at the bottom of the support rod 2. Since the arc area is wider at the top and narrower at the bottom, the pressure on the narrower surface is greater than that on the wider surface, making it easier to break the balance state. Coupled with the characteristics of the arc, the liquid can flow smoothly from the second cavity 22 to the sealing cavity.

[0076] Since both the support rod 2 and the base 1 are cylindrical, the overall center of gravity is on the axis of the cylinder. When the liquid flows, it can stably transfer from a higher position to a lower position. Until P1 = P2, h1 and h2 will no longer change. At this time, the whole machine is not easy to倾倒 during operation.

[0077] Recovery stage:

[0078] In the recovery stage, the lifting rod 3 moves downward (in the opposite direction as indicated by the arrow in Figure 12 ), at this time the volume of the sealed sealing cavity decreases, resulting in an increase in P2 气 . The pressure balance between the second cavity 22 and the sealing cavity is broken (P1 < P2). To re - achieve the pressure balance state between the two cavities, the height h2 of the liquid in the sealing cavity will decrease, and the height h1 of the liquid in the second cavity 22 will increase. The liquid flows through the arc area at the bottom of the support rod 2. Since the arc area is wider at the top and narrower at the bottom, the force on the narrower surface is greater than that on the wider surface, making it easier to break the balance state. Coupled with the characteristics of the arc, the liquid flows smoothly from the sealing cavity to the second cavity 22. Until P1 = P2, h1 returns to the initial position height. The center of gravity of the whole machine returns to the initial state position (switching to the state shown in Figure 9 and Figure 10 ), at this time the whole machine is convenient to move and its flexibility is improved, thus completing a cycle.

[0079] This application cleverly designs the characteristics of the support rod 2 and the base 1, and at the same time adjusts the center of gravity of the whole machine through Pascal's principle. The process is stable and natural, greatly improving the stability of the product.
