It has a built-in 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 gyms, sports medicine centers, professional sports teams and other occasions. Especially in professional sports teams, physical fitness testers can be used to monitor the competitive state of athletes outdoors to provide reference for competition strategies.

[0004] When the existing mobile power supply provides power for the physical fitness tester, since the physical fitness tester needs to work for a long time to detect the competitive state of the athletes, the mobile power supply also needs to work for a long time with the physical fitness tester. The mobile power supply is packaged in a fully enclosed structure, which causes the mobile power supply to heat up seriously when working for a long time, posing certain safety hazards. Summary of the invention

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

[0006] The technical solution of the present application is as follows: A physical fitness tester using an outdoor mobile power supply, comprising: A mobile power source body, wherein a battery core assembly is provided inside the mobile power source body, a water cooling box is provided on one side of the outside of the mobile power source body, a heat exchanger is provided on the battery core assembly, the heat exchanger is connected to the water cooling box, and an auxiliary heat sink is provided inside the water cooling box; The outer shell component comprises an outer shell body and a silicone chassis, wherein the outer shell body and the silicone chassis are respectively arranged at the upper and lower ends of the outside of the mobile power supply body, the outer shell body and the silicone chassis are connected to each other and wrap and enclose the mobile power supply body, an interlayer is arranged inside the silicone chassis, the bottom of the water cooling box is connected to the interlayer, the water cooling box, the heat exchange component and the silicone chassis are all filled with a cooling medium that can absorb heat and expand, the auxiliary heat sink can float on the liquid surface of the cooling medium, one end of the auxiliary heat sink extends below the liquid surface of the cooling medium, and the other end passes through the water cooling box and extends to the outside of the water cooling box, and when the liquid level of the cooling medium rises, the other end of the auxiliary heat sink can be driven to move to the outside of the water cooling box.

[0007] By adopting the above scheme, after the device is placed, the silicone base plate is pressed by its own gravity, so that the cooling medium inside the interlayer is squeezed out, thereby causing the liquid level of the cooling medium inside the water-cooling box to rise, thereby driving the other end of the auxiliary heat sink 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 sink to the other end for heat dissipation. When the device works for a long time, the cooling medium can also expand by absorbing heat, so that the auxiliary heat sink further rises and moves as the liquid level rises, so that the volume of the other end of the auxiliary heat sink extending to the outside of the water-cooling box increases, and the heat exchange area increases, so that the device can further improve the heat dissipation efficiency according to the working conditions of the device; In addition, a silicone chassis is set at the lower end of the shell component, and a sandwich layer is set inside the silicone chassis, so that when the shell component is placed on a plane, the silicone chassis can be deformed according to the unevenness of the placement surface, so that the device can be placed stably outdoors.

[0008] In one embodiment of the present application, the auxiliary heat sink comprises: A floating plate, wherein the floating plate is disposed inside the water cooling box, and the density of the floating plate is less than the density of the cooling medium; A copper heat-conducting rod is vertically mounted on the floating plate, the upper end of the copper heat-conducting rod passes 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.

[0009] By adopting the above technical solution, the density of the floating plate is less than the density of the cooling medium, so the floating plate can float on the surface of the cooling medium, and can drive the copper heat-conducting rod to rise as the cooling medium level rises, thereby improving the heat dissipation efficiency of the copper heat-conducting rod.

[0010] In one embodiment of the present application, a plurality of key grooves are provided on the outside of the copper heat-conducting rod along its circumference, and the key grooves extend along the length direction of the copper heat-conducting rod. A strip-shaped cavity extending along the length direction of the copper heat-conducting rod is provided inside the copper heat-conducting rod.

[0011] By adopting the above solution, a keyway is arranged on the outside of the copper heat-conducting rod. When the other end of the copper heat-conducting rod extends out of the water cooling box, the keyway can play a guiding role and increase the heat exchange area between the copper heat-conducting rod and the external air, so that the heat exchange efficiency of the copper heat-conducting rod is further improved. At the same time, by adding a low-temperature medium, such as ice water, into the strip cavity inside the copper heat-conducting rod, the copper heat-conducting rod can be quickly cooled down in an emergency, thereby reducing the temperature of the cooling medium in the water cooling box.

[0012] In one embodiment of the present application, a water inlet pipe and a water outlet pipe are respectively provided on one side of the bottom end of the water cooling box close to the mobile power supply body, and a one-way valve is provided on the end of the water inlet pipe and the water outlet pipe away from the water cooling box, and are respectively connected to the heat exchange element, and telescopic hoses are provided on both sides of the bottom end of the water cooling box, and the two ends of the telescopic hoses are respectively connected to the water cooling box and the interlayer.

[0013] By adopting the above scheme, by connecting the water cooling box and the heat exchange element to each other, and connecting the water cooling box and the interlayer at the same time, the entire interlayer is first filled with cooling medium, and the cooling medium after absorbing heat inside the heat exchange element can also automatically enter the water cooling box and the interlayer for cooling. In addition, when the device falls during transportation, the cooling medium inside the interlayer can provide a certain buffering effect, reducing the impact on the device when it falls to the ground.

[0014] In one embodiment of the present application, the mobile power source body further comprises a power frame, the battery cell assembly is arranged in the power frame, an electric control board assembly electrically connected to the battery cell assembly is provided on the other side of the power frame, and a plurality of interfaces are provided on the electric control board assembly.

[0015] By adopting the above solution, when the device supplies power to other equipment, the power supply line is inserted into the interface, thereby achieving electrical interconnection between the device and the other equipment.

[0016] In one embodiment of the present application, the battery cell assembly includes: A battery base, the battery base is fixedly mounted inside the power frame, and a plurality of battery cells electrically connected to the electric control board assembly are mounted on the battery base; A protective frame is sleeved on the outside of the plurality of battery cells.

[0017] In one embodiment of the present application, the outdoor mobile power supply of the physical fitness tester further includes a plurality of heat conductive members, and the plurality of heat conductive members are vertically arranged below the power supply frame, and the heat conductive members include: A placement seat, the silicone chassis is provided with a plurality of placement holes extending along the thickness direction of the silicone chassis, the placement seat is arranged in the placement holes, and the upper and lower ends of the placement seat are sleeved with limit rings, which are used to clamp the power frame and the silicone chassis respectively; A heat-conducting rod, the upper end of the placement seat passes through the power frame, the heat-conducting rod is assembled on the upper end of the placement seat, the heat-conducting rod is provided with a plurality of annular heat dissipation grooves at intervals along its length direction, and the placement seat and the heat-conducting rod are both copper components.

[0018] By adopting the above solution, by setting a plurality of placement seats, the placement seats are placed under the silicone chassis and in contact with the placement surface, thereby improving the placement stability of the device. At the same time, heat conduction rods are provided on the placement seats, and the heat conduction rods 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.

[0019] In one embodiment of the present application, the outdoor mobile power supply for physical fitness tester further includes: A handle, the handle is rotatably assembled on the outer housing; A protective plate, the protective plate 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 housing close to the electronic control board assembly.

[0020] By adopting the above solution, by setting a handle, when transporting the device, by pulling the handle, it is convenient for the user to carry and transport the device, improving the portability of the device.

[0021] In one embodiment of the present application, the heat exchange member includes: Metal heat exchange fins 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 fins are in contact with the outer walls of the adjacent battery cells; A connecting piece with a hollow interior, and a plurality of the metal heat exchange fins are connected through the connecting piece.

[0022] By adopting the above solution, 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, improving the heat exchange efficiency of the heat exchange member.

[0023] In one embodiment 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; When the outer 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, and 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.

[0024] By adopting the above solution, when the device is placed on a plane, due to the extrusion of the device gravity on the silicone chassis, the cooling medium in the sandwich layer is input into the system composed of the metal heat exchange fins and the water cooling box due to the extrusion. At this time, the cooling medium fills the inside of the metal heat exchange fins until the liquid level height of the cooling medium inside the water cooling box is higher than the height of the metal heat exchange fins, so that when the device works later, the volume expansion of the cooling medium after absorbing 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 fins is always filled with the cooling medium.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: By adopting a heat exchanger, the cooling medium inside the heat exchanger 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 cooling medium liquid level inside the water cooling box to rise, driving the auxiliary heat sink floating on the cooling medium liquid level to move. The other end of the auxiliary heat sink can move toward the outside of the water cooling box, thereby increasing the heat exchange area between it and the air, and improving the heat dissipation capacity of the auxiliary heat sink, thereby improving the heat dissipation capacity of the cooling medium, and making the device more energy-efficient while ensuring the heat dissipation capacity of the device.

[0026] By adopting a silicone base, setting an interlayer on the silicone base, and filling the interlayer with a cooling medium, when the device falls on the ground, the cooling medium inside the interlayer can provide a certain buffer. At the same time, when the device is placed in an outdoor environment, the silicone base can be deformed according to the unevenness of the placement surface, thereby improving the stability of the device when placed.

[0027] By adopting and arranging the heat-conducting rods, when the device is placed on a placement plane, multiple heat-conducting rods can all be in stable contact with the placement surface, thereby improving the stability of the entire device when placed, so that it will not shake due to the elasticity of the silicone base. At the same time, since the placement seat and the heat-conducting rods are both copper components, the heat-conducting rods can promptly export the heat inside the mobile power supply body.

[0028] By limiting the height of the liquid level inside the water cooling box and the height of the metal heat exchanger fin when the device is placed on a plane, when the device is placed, the silicone base below is squeezed and deformed by the weight of the device itself. When the cooling medium is squeezed into the water cooling box and the metal heat exchanger fin, the liquid level inside the water cooling box can be directly raised, while ensuring that the cooling medium inside the metal heat exchanger fin is always filled, so as to improve the heat exchange effect.

[0034] See also Figure 2The battery cell assembly 11 includes a battery cell base 111 and a protective frame 112. The battery cell base 111 is fixedly installed inside the power frame 19. A plurality of battery cells 1111 electrically connected to the electric control board assembly 191 are installed on the battery cell base 111. The protective frame 112 is sleeved on the outside of the plurality of battery cells 1111. By integrating and connecting with the electric control board assembly 191, the device can be stably powered.

[0035] See also Figure 2 and Figure 4 The heat exchange element 13 includes a metal heat exchange plate 131 and a connecting plate 132. The metal heat exchange plate 131 and the connecting plate 132 are hollow inside. Multiple metal heat exchange plates 131 are arranged in the gap between the battery cells 1111. Both sides of the metal heat exchange plate 131 are in contact with the outer wall of the adjacent battery cell 1111. The multiple metal heat exchange plates 131 are connected by the connecting plate 132. The multiple metal heat exchange plates 131 are inserted into the gap between the battery cells 1111, so that the heat at each battery cell 1111 can be absorbed, thereby improving the device's heat absorption capacity for the battery cells 1111 inside the device.

[0036] The outer shell assembly 2 includes an outer shell body 21 and a silicone chassis 22. The outer shell body 21 and the silicone chassis 22 are respectively arranged at the upper and lower ends of the outside of the mobile power supply body 1. The outer shell body 21 and the silicone chassis 22 are connected to each other and wrap around the mobile power supply body 1. An interlayer 221 is provided inside the silicone chassis 22, and the bottom of the water cooling box 12 is connected to the interlayer 221.

[0037] The water-cooling box 12, the heat exchanger 13 and the silicone chassis 22 are all filled with a cooling medium 3 that can absorb heat and expand. The auxiliary heat sink 14 can float on the liquid surface of the cooling medium 3. One end of the auxiliary heat sink 14 extends below the liquid surface of the cooling medium 3, and the other end penetrates the water-cooling box 12 and extends to the outside of the water-cooling box 12. When the cooling medium 3 absorbs heat and the liquid level rises, the other end of the auxiliary heat sink 14 can be driven to move to the outside of the water-cooling box 12. The silicone chassis 22, the heat exchanger 13 and the water-cooling box 12 are filled with the cooling medium 3. The cooling medium 3 can not only reduce the impact force when the device falls, but also the cooling medium 3 can drive the auxiliary heat sink 14 to move after absorbing heat and expanding. In the absence of external power input, the device can automatically improve the heat dissipation capacity under long-term working conditions.

[0038] In this embodiment, the cooling medium 3 may be water or acetone solution.

[0039] See also Figure 5 and Figure 6 The auxiliary heat sink 14 includes a floating plate 141 and a copper heat conducting rod 142 .

[0040] The floating plate 141 is arranged inside the water cooling box 12, and the density of the floating plate 141 is less than the density of the cooling medium 3. The copper heat-conducting rod 142 is vertically assembled on the floating plate 141.

The water cooling box 12 is provided with a plurality of sealing rings (not shown) matching the shape of the copper heat-conducting rod 142 on the outside of the copper heat-conducting rod 142, and the lower end extends below the liquid surface of the cooling medium 3. By providing the floating plate 141 with a density less than that of the cooling medium 3, the liquid surface of the cooling medium 3 inside the water cooling box 12 can drive the floating plate 141 floating on the surface of the cooling medium 3 to rise when evaporating. When the device works for a long time with the physical fitness tester and heats up, the floating plate 141 can move with the liquid surface and drive the copper heat-conducting rod 142 to extend to the outside of the water cooling box 12, so as to improve the heat dissipation capacity of the device.

[0041] In this embodiment, the floating board 141 may be a polystyrene foam board.

[0042] See also Figure 7 The copper heat-conducting rod 142 has a plurality of key grooves 1421 formed on its outside along its circumference, and the key grooves 1421 extend along the length direction of the copper heat-conducting rod 142. The copper heat-conducting rod 142 has a strip-shaped cavity 1422 formed on its inside along its length direction. By forming a plurality of key grooves 1421 on the outside of the copper heat-conducting component 4, the heat exchange area between the copper heat-conducting component 4 and the external air is increased, thereby improving the heat exchange efficiency of the device.

[0043] Please continue reading Figure 2 and Figure 4 A water inlet pipe 15 and a water outlet pipe 16 are respectively provided on the side of the bottom of the water cooling box 12 close to the mobile power supply body 1. The ends of the water inlet pipe 15 and the water outlet pipe 16 away from the water cooling box 12 are provided with a one-way valve 17, and are respectively connected to the heat exchanger 13. A telescopic hose 18 is provided on both sides of the bottom of the water cooling box 12. The two ends of the telescopic hose 18 are respectively connected to the water cooling box 12 and the interlayer 221. By providing the one-way valve 17, the cooling medium 3 can flow into the water cooling box 12 from the water outlet pipe 16 after absorbing heat and expanding, and after being cooled by the copper heat conductive part 4 inside the water cooling box 12, it re-enters the heat exchanger 13, thereby realizing the circulation of the cooling medium 3.

[0044] Please continue reading Figure 1 and Figure 2 The mobile power main body 1 also includes a power frame 19, and the battery cell assembly 11 is arranged in the power frame 19. The other side of the power frame 19 is provided with an electric control board assembly 191 electrically connected to the battery cell assembly 11. The electric control board assembly 191 is provided with a plurality of interfaces 1911. By setting a plurality of interfaces 1911, the device can be connected according to different devices and using a data cable to supply power.

[0045] Please refer to Figure 2 and Figure 3 The outdoor mobile power supply for the physical fitness tester further includes a plurality of heat conducting members 4. The plurality of heat conducting members 4 are all vertically arranged below the power supply frame 19. The heat conducting member 4 includes a placement seat 41 and a heat conducting rod 42. The silica gel chassis 22 is provided with a plurality of placement holes 222 extending along the thickness direction of the silica gel chassis 22. The placement seat 41 is arranged in the placement hole 222. Limiting rings 411 are sleeved on both the upper and lower ends of the placement seat 41 and are respectively used to clamp the power supply frame 19 and the silica gel chassis 22. The upper end of the placement seat 41 penetrates through the power supply frame 19. The heat conducting rod 42 is assembled on the upper end of the placement seat 41. A plurality of annular heat dissipation grooves 421 are arranged at intervals along the length direction of the heat conducting rod 42. Both the placement seat 41 and the heat conducting rod 42 are made of copper components. By providing the heat conducting rod 42 capable of导出 the heat inside the power supply frame 19, while the device can deform according to the unevenness of the placement surface, and with the cooperation of a plurality of placement seats 41, it is ensured that the device will not wobble when placed. In addition, the heat conducting rod 42 can timely导出 the heat inside the power supply frame 19.

[0046] In a further embodiment, please refer to Figure 6 and Figure 8 The height h of the water cooling box 12 and the height d of the metal heat exchange fin 131 itself satisfy: d < h. When the outer shell assembly 2 is placed on a plane, the liquid level height m of the cooling medium 3 inside the water cooling box 12 and the height d of the metal heat exchange fin 131 satisfy: d < m. At this time, there is an expansion gap 121 between the upper surface of the floating plate and the inner wall of the upper end of the water cooling box 12. By限定 the height of the cooling medium 3 inside the water cooling box 12 when the device is placed, it is ensured that the cooling medium 3 can always fill the inside of the metal heat exchange fin 131 when the device is placed, so as to保证 the heat exchange efficiency of the cooling medium 3.

[0047] Please continue to refer to Figure 1 The outdoor mobile power supply for the physical fitness tester further includes a handle 5 and a protection plate 6.

[0048] The handle 5 is rotatably assembled on the outer shell 21. The protection plate 6 is located on the side of the electronic 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 electronic control board assembly 191. By providing the handle 5 and the protection plate 6, the handle 5 makes it more convenient to carry the device during transportation.

[0049] In summary, when the device supplies power to the physical fitness tester for a long time, the cooling medium 3 located inside the metal heat exchange plate 131 can absorb the heat generated when the battery cell 1111 is working. 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 increases, which can drive the floating plate 141 floating on the liquid surface of the cooling medium 3 to rise, so that the length of the upper end of the copper heat-conducting rod 142 extending outside the water cooling box 12 becomes longer. Since the lower end of the copper heat-conducting rod 142 is always below the liquid surface of the cooling medium 3, the copper heat-conducting rod 142 can transfer the temperature of the lower end to the upper end and dissipate it in the air, so that the device can automatically adjust the heat dissipation capacity of the device under long-term working conditions without additional power input.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
