Abstract

This application relates to an outdoor mobile power supply for a physical fitness tester, comprising: a mobile power supply main body and a housing assembly. Inside the mobile power supply main body, there is a battery cell assembly. On one side outside the mobile power supply main body, there is a water cooling box. A heat exchange component is provided on the battery cell assembly, and the heat exchange component is communicated with the water cooling box. An auxiliary heat dissipation component is provided inside the water cooling box. Due to its own gravity pressing on the silicone chassis, the liquid level height of the cooling medium inside the water cooling box rises, thereby driving the other end of the auxiliary heat dissipation component to extend outside the water cooling box. At the same time, the heat of the cooling medium is transferred from one end of the auxiliary heat dissipation component to the other end for heat dissipation. When the device works for a long time, the cooling medium can also expand by absorbing heat, causing the auxiliary heat dissipation component to further rise and move as the liquid level height rises, so that the volume of the other end of the auxiliary heat dissipation component extending outside the water cooling box increases, and the heat exchange area increases. Furthermore, the device can further improve the heat dissipation efficiency according to the working conditions of the device.

Description

Technical Field

[0001] This application relates to the technical field of mobile power supplies, and particularly to an outdoor mobile power supply for a physical fitness tester. Background Art

[0002] A mobile power supply, also often referred to as a power bank or a portable charger, is a personal portable charging device mainly used to provide external power for other electronic devices that require electricity, such as mobile phones, tablet computers, digital cameras, etc. It is internally equipped with a battery (usually a lithium-ion battery or a lithium polymer battery), and has one or more USB output ports that can be connected to a data cable to charge other devices.

[0003] Physical fitness testers are widely used in various occasions such as gyms, sports medicine centers, and professional sports teams. Especially in professional sports teams, the competitive state of athletes can be monitored outdoors through physical fitness testers, providing a reference for game strategies.

[0004] When the existing mobile power supply provides electrical energy for a physical fitness tester, since the physical fitness tester needs to work for a long time to detect the competitive state of athletes, the mobile power supply also needs to work with the physical fitness tester for a long time. However, the mobile power supply is encapsulated in a fully enclosed structure, which leads to serious heat generation during long-term operation of the mobile power supply, posing certain potential safety hazards. Summary of the Invention

[0005] This application provides an outdoor mobile power supply for a physical fitness tester, which can solve the problem of poor heat dissipation when the existing mobile power supply outputs electrical energy for a long time while ensuring the airtightness of the structure.

[0006] The technical solution of this application is as follows: An outdoor mobile power supply for a physical fitness tester includes:

[0007] A mobile power supply main body, inside which there is a battery cell assembly. On one side outside the mobile power supply main body, there is a water cooling box. A heat exchange member is provided on the battery cell assembly, and the heat exchange member is communicated with the water cooling box. An auxiliary heat dissipation member is provided inside the water cooling box;

[0008] The housing assembly, the housing assembly includes a housing body and a silicone chassis. The housing body and the silicone chassis are respectively arranged at the upper and lower ends outside the mobile power supply body. The housing body and the silicone chassis are connected to each other and wrap around the mobile power supply body. There is a sandwich layer inside the silicone chassis. The bottom of the water cooling box is communicated with the sandwich layer. The water cooling box, the heat exchange member and the inside of the silicone chassis are all filled with a cooling medium that can absorb heat and expand. The auxiliary heat dissipation member can float on the liquid surface of the cooling medium. One end of the auxiliary heat dissipation member extends below the liquid surface of the cooling medium, and the other end penetrates through the water cooling box and extends outside the water cooling box. When the liquid level of the cooling medium rises, it can drive the other end of the auxiliary heat dissipation member to move outside the water cooling box.

[0009] By adopting the above scheme, after the device is placed, due to its own gravity pressing on the silicone chassis, the cooling medium inside the sandwich layer is extruded, so that the liquid level height of the cooling medium inside the water cooling box rises, which in turn drives the other end of the auxiliary heat dissipation member to extend outside the water cooling box. At the same time, the heat of the cooling medium is transferred from one end of the auxiliary heat dissipation member to the other end for heat dissipation. When the device works for a long time, the cooling medium can also absorb heat and expand, so that the auxiliary heat dissipation member further rises as the liquid level rises, making the volume of the other end of the auxiliary heat dissipation member extending outside the water cooling box increase and the heat exchange area increase, thereby enabling the device to further improve the heat dissipation efficiency according to the working conditions of the device.

[0010] In addition, a silicone chassis is provided at the lower end of the housing assembly, and a sandwich layer is provided inside the silicone chassis. When the housing assembly is placed on a plane, the silicone chassis can deform according to the unevenness of the placement surface, so that the device can be stably placed outdoors.

[0011] In one embodiment of the present application, the auxiliary heat dissipation member includes:

[0012] A floating plate, the floating plate is arranged inside the water cooling box, and the density of the floating plate is less than the density of the cooling medium;

[0013] A copper heat conduction rod, the copper heat conduction rod is vertically assembled on the floating plate, the upper end of the copper heat conduction rod penetrates through the water cooling box and is slidably connected to the water cooling box, and the lower end extends below the liquid surface of the cooling medium.

[0014] By adopting the above technical scheme, the density of the floating plate is less than the density of the cooling medium, so the floating plate can float on the liquid surface of the cooling medium and can drive the copper heat conduction rod to rise as the liquid level of the cooling medium rises, thereby improving the heat dissipation efficiency of the copper heat conduction rod.

[0015] In one embodiment of the present application, a plurality of key grooves are formed on the outer circumference of the red copper heat conduction rod along its own circumferential direction. The key grooves extend along the length direction of the red copper heat conduction rod, and a strip-shaped cavity extending along the length direction of the red copper heat conduction rod is formed inside the red copper heat conduction rod.

[0016] By adopting the above solution, key grooves are arranged on the outside of the red copper heat conduction rod. When the other end of the red copper heat conduction rod extends out of the water cooling box, the key grooves can play a guiding role and at the same time increase the heat exchange area between the red copper heat conduction rod and the external air, further improving the heat exchange efficiency of the red copper heat conduction rod.

[0017] At the same time, by adding a low-temperature medium, such as ice water, etc., into the strip-shaped cavity inside the red copper heat conduction rod, the red copper heat conduction rod can quickly cool down in case of emergency, thereby reducing the temperature of the cooling medium in the water cooling box.

[0018] In one embodiment of the present application, a water inlet pipe and a water outlet pipe are respectively arranged on one side of the bottom end of the water cooling box close to the mobile power supply main body. One-way valves are arranged at the ends of the water inlet pipe and the water outlet pipe far away from the water cooling box, and they are respectively communicated with the heat exchange member. Expansion hoses are arranged on both sides of the bottom end of the water cooling box, and both ends of the expansion hoses are respectively communicated with the water cooling box and the interlayer.

[0019] By adopting the above solution, by connecting the water cooling box and the heat exchange member to each other, and at the same time connecting the water cooling box with the interlayer, the entire interlayer is first filled with the cooling medium, and the cooling medium that absorbs heat inside the heat exchange member can also automatically enter the water cooling box and the interlayer for cooling. In addition, when the device drops during transportation, the cooling medium inside the interlayer can provide a certain buffering effect and reduce the impact when the device falls to the ground.

[0020] In one embodiment of the present application, the mobile power supply main body further includes a power supply frame. The battery cell assembly is arranged in the power supply frame. An electronic control board assembly electrically connected to the battery cell assembly is arranged on the other side of the power supply frame, and a plurality of interfaces are arranged on the electronic control board assembly.

[0021] By adopting the above solution, when the device supplies power to other devices, the device and other devices can be electrically interconnected by inserting a power supply line into the interface.

[0022] In one embodiment of the present application, the battery cell assembly includes:

[0023] A battery cell base, which is fixedly assembled inside the power supply frame. A plurality of battery cells electrically connected to the electronic control board assembly are assembled on the battery cell base;

[0024] A protective frame, which is sleeved outside the plurality of battery cells.

[0025] In one embodiment of the present application, the outdoor mobile power supply for the physical fitness tester further includes a plurality of heat conducting members, and the plurality of heat conducting members are all vertically arranged below the power supply frame. The heat conducting members include:

[0026] A placement seat. The silicone chassis is provided with a plurality of placement holes extending in the thickness direction of the silicone chassis. The placement seat is arranged in the placement holes, and limiting rings are sleeved on both the upper and lower ends of the placement seat, and are respectively used to clamp the power supply frame and the silicone chassis;

[0027] A heat conducting rod. The upper end of the placement seat penetrates through the power supply frame, and the heat conducting rod is assembled at the upper end of the placement seat. A plurality of annular heat dissipation grooves are arranged at intervals along the length direction of the heat conducting rod. Both the placement seat and the heat conducting rod are made of copper components.

[0028] By adopting the above scheme, by arranging a plurality of placement seats, the placement seats are placed below the silicone chassis and are in contact with the placement surface, thereby improving the placement stability of the device. At the same time, a heat conducting rod is arranged on the placement seat, and the heat conducting rod can conduct the heat inside the power supply frame to the outside of the device, thereby further improving the heat dissipation capacity of the device.

[0029] In one embodiment of the present application, the outdoor mobile power supply for the physical fitness tester further includes:

[0030] A handle, which is rotatably assembled on the outer shell;

[0031] A protection plate, which is located on the side of the electronic control board assembly away from the water cooling box and is hinged to the inner wall of one end of the outer shell close to the electronic control board assembly.

[0032] By adopting the above scheme, by arranging a handle, when carrying and transporting the device, by pulling the handle, it is convenient for the user to carry and transport the device, and the portability of the device is improved.

[0033] In one embodiment of the present application, the heat exchange member includes:

[0034] A metal heat exchange fin with a hollow interior. A plurality of the metal heat exchange fins are arranged in the gaps between the battery cells, and both sides of the metal heat exchange fin are in contact with the outer walls of the adjacent battery cells;

[0035] A communicating piece with a hollow interior. A plurality of the metal heat exchange fins are communicated through the communicating piece.

[0036] By adopting the above scheme, by arranging a plurality of metal heat exchange fins in the gaps between adjacent battery cells, the metal heat exchange fins can quickly conduct the heat inside the battery cells, and the heat exchange efficiency of the heat exchange member is improved.

[0037] In one of the embodiments of the present application, the height h of the water-cooling box and the height d of the metal heat exchange fin itself satisfy: d < h;

[0038] When the housing assembly is placed on a plane, the liquid level height m of the cooling medium inside the water-cooling box and the height d of the metal heat exchange fin satisfy: d < m. At this time, there is an expansion gap between the upper surface of the foam board and the inner wall of the upper end of the water-cooling box.

[0039] By adopting the above solution, when the device is placed on a plane, due to the extrusion of the silicone chassis by the gravity of the device, the cooling medium located in the sandwich is input into the system composed of the metal heat exchange fin and the water-cooling box due to the extrusion. At this time, the cooling medium fills the inside of the metal heat exchange fin until the liquid level height of the cooling medium inside the water-cooling box is higher than the height of the metal heat exchange fin, so that when the device works subsequently, the volume expansion generated after the cooling medium absorbs heat can directly drive the rise of the liquid level height of the cooling medium, and at the same time ensure that the inside of the metal heat exchange fin is always filled with the cooling medium.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] By adopting a heat exchange component, the cooling medium inside the heat exchange component absorbs the heat of the battery cell. When the device works with the physical fitness tester, the cooling medium can absorb heat and expand, thereby causing the liquid level of the cooling medium inside the water-cooling box to rise, driving the movement of the auxiliary heat dissipation component floating on the liquid surface of the cooling medium. The other end of the auxiliary heat dissipation component can move towards the outside of the water-cooling box, increasing its heat exchange area with the air and improving the heat dissipation capacity of the auxiliary heat dissipation component, thereby improving the heat dissipation capacity of the cooling medium. It also makes the device more energy-efficient while ensuring the heat dissipation capacity of the device.

[0042] By adopting a silicone base, a sandwich is provided on the silicone base and a cooling medium is filled in the sandwich, so that when the device falls to the ground, the cooling medium inside the sandwich can provide a certain buffer. At the same time, when the device is placed in an outdoor environment, the silicone base can deform according to the unevenness of the placement surface, thereby improving the stability of the device when placed.

[0043] By adopting heat conduction rods, by setting heat conduction rods, when the device is placed on a placement plane, multiple heat conduction rods can all be in stable contact with the placement surface, thereby improving the stability of the entire device when placed and preventing it from shaking randomly due to the elasticity of the silicone base. At the same time, since both the placement seat and the heat conduction rods are made of copper components, the heat conduction rods can timely conduct the heat inside the power supply main body.

[0044] When the limiting device is placed on a plane, the height of the liquid level inside the water-cooling box and the height of the metal heat exchanger are limited. When the device is placed, the silicone base below is deformed by the weight of the device itself. After the cooling medium is squeezed into the water-cooling box and the metal heat exchanger, it can directly cause the liquid level inside the water-cooling box to rise, and at the same time ensure that the cooling medium inside the metal heat exchanger is always full to improve the heat exchange effect.

Both sides of the metal heat exchange fins 131 are in contact with the outer walls of the adjacent battery cells 1111. A plurality of metal heat exchange fins 131 are connected through the connecting pieces 132. By inserting the plurality of metal heat exchange fins 131 into the gaps between the battery cells 1111, the heat at each battery cell 1111 can be absorbed, thereby improving the heat absorption capacity of the device for the battery cells 1111 inside the device.

[0059] The housing assembly 2 includes a housing body 21 and a silica gel chassis 22. The housing body 21 and the silica gel chassis 22 are respectively arranged at the upper and lower ends outside the mobile power supply main body 1. The housing body 21 and the silica gel chassis 22 are connected to each other and wrap around the mobile power supply main body 1. A sandwich layer 221 is provided inside the silica gel chassis 22. The bottom of the water cooling box 12 is communicated with the sandwich layer 221.

[0060] The water cooling box 12, the heat exchange member 13, and the silica gel chassis 22 are all filled with a cooling medium 3 that can absorb heat and expand. The auxiliary heat dissipation member 14 can float on the liquid surface of the cooling medium 3. One end of the auxiliary heat dissipation member 14 extends below the liquid surface of the cooling medium 3, and the other end penetrates through the water cooling box 12 and extends outside the water cooling box 12. When the cooling medium 3 absorbs heat and the liquid level rises, it can drive the other end of the auxiliary heat dissipation member 14 to move outside the water cooling box 12. The cooling medium 3 fills the silica gel chassis 22, the heat exchange member 13, and the water cooling box 12. The cooling medium 3 can not only reduce the impact force when the device falls, but also drive the auxiliary heat dissipation member 14 to move after absorbing heat and expanding.

[0061] In this embodiment, the cooling medium 3 can be water or an acetone solution.

[0062] Please refer to Figure 5 and Figure 6 , the auxiliary heat dissipation member 14 includes a floating plate 141 and a copper heat conduction rod 142.

By providing the floating plate 141 with a density less than that of the cooling medium 3, when the liquid level of the cooling medium 3 inside the water cooling box 12 evaporates and rises, the floating plate 141 floating on the surface of the cooling medium 3 can be driven to rise together, so that when the device works with the physical fitness tester for a long time and heats up, the floating plate 141 can move along with the liquid level and drive the copper heat conduction rod 142 to extend outside the water cooling box 12 to improve the heat dissipation capacity of the device.

[0064] In this embodiment, the floating plate 141 can be a polystyrene foam board.

[0065] Please refer to Figure 7 , a plurality of key grooves 1421 are axially formed on the outer circumference of the copper heat conduction rod 142. The key grooves 1421 extend along the length direction of the copper heat conduction rod 142. A strip-shaped cavity 1422 extending along the length direction of the copper heat conduction rod 142 is formed inside the copper heat conduction rod 142. By providing a plurality of key grooves 1421 on the outside of the copper heat conduction member 4, the heat exchange area between the copper heat conduction member 4 and the external air is increased, thereby improving the heat exchange efficiency of the device.

[0066] Please continue to refer to Figure 2 and Figure 4 , a water inlet pipe 15 and a water outlet pipe 16 are respectively provided on one side of the bottom end of the water cooling box 12 close to the mobile power supply main body 1.

Expansion hoses 18 are provided on both sides of the bottom end of the water cooling box 12. Both ends of the expansion hoses 18 are respectively communicated with the water cooling box 12 and the interlayer 221. By providing the one-way valves 17, after the cooling medium 3 absorbs heat and expands, it can flow into the water cooling box 12 from the water outlet pipe 16, and after being cooled by the copper heat conduction member 4 inside the water cooling box 12, it can re-enter the heat exchange member 13, thereby realizing the circulation of the cooling medium 3.

[0067] Please continue to refer to Figure 1 and Figure 2 , the mobile power supply main body 1 further includes a power supply frame 19. The battery cell assembly 11 is disposed in the power supply frame 19. An electronic control board assembly 191 electrically connected to the battery cell assembly 11 is provided on the other side of the power supply frame 19. A plurality of interfaces 1911 are provided on the electronic control board assembly 191. By providing the plurality of interfaces 1911, the device can be connected according to different devices and using data lines for power supply.

[0068] See also Figure 2 and Figure 3 The outdoor mobile power supply for the physical fitness tester also includes a plurality of heat-conducting parts 4, which are vertically arranged below the power frame 19. The heat-conducting parts 4 include a placement seat 41 and a heat-conducting rod 42. The silicone chassis 22 is provided with a plurality of placement holes 222 extending along the thickness direction of the silicone chassis 22. The placement seat 41 is arranged in the placement hole 222. The upper and lower ends of the placement seat 41 are sleeved with limit rings 411, which are used to clamp the power frame 19 and the silicone chassis 22 respectively. The upper end of the placement seat 41 penetrates the power frame 19, a heat-conducting rod 42 is assembled on the upper end of the placement seat 41, and a plurality of annular heat dissipation grooves 421 are arranged at intervals along the length direction of the heat-conducting rod 42. The placement seat 41 and the heat-conducting rod 42 are both copper components. By arranging the heat-conducting rod 42 that can export the heat inside the power frame 19, the device can be deformed according to the unevenness of the placement surface, and the plurality of placement seats 41 are used to cooperate to achieve that the device will not shake when it is placed. In addition, the heat-conducting rod 42 can export the heat inside the power frame 19 in time.

[0069] In a further embodiment, see Figure 6 and Figure 8 , the height h of the water cooling box 12 and the height d of the metal heat exchanger 131 satisfy: d <h,当外壳组件2放置于平面上时,水冷箱12内部冷却介质3的液面高度m和金属换热片131的高度d满足:d<m,此时漂浮板上表面与水冷箱12上端内壁之间留有膨胀空隙121,通过限定装置放置时水冷箱12内部的冷却介质3高度,从而使得装置在放置时,金属换热片131内部的始终能够填充满冷却介质3,以保证冷却介质3的热交换效率。

[0070] Please continue reading Figure 1 The outdoor mobile power supply of the physical fitness tester also includes a handle 5 and a protective plate 6.

[0071] The handle 5 is rotatably mounted on the outer shell 21, the protective plate 6 is located on the side of the electric control board assembly 191 away from the water cooling box 12, and is hinged to the inner wall of one end of the outer shell 21 close to the electric control board assembly 191. By arranging the handle 5 and the protective plate 6, the handle 5 is used to make the device more convenient to carry during transportation.

[0072] In summary, when the device supplies power to the physical fitness tester for a long time, the cooling medium 3 inside the metal heat exchanger 131 can absorb the heat generated during the operation of the battery cell 1111. At the same time, the cooling medium 3 expands and automatically flows into the water cooling box 12. The liquid surface temperature of the cooling medium 3 inside the water cooling box 12 rises, which can drive the floating plate 141 floating on the liquid surface of the cooling medium 3 to rise, making the length of the upper end of the copper heat conduction rod 142 extending outside the water cooling box 12 longer. Since the lower end of the copper heat conduction rod 142 is always below the liquid surface of the cooling medium 3, the copper heat conduction rod 142 can transfer the temperature at the lower end to the upper end and dissipate it into the air. Thus, when the device is in a long-term working state, it can automatically adjust the heat dissipation capacity of the device without additional power input.

[0073] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
