For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0023] This embodiment aims to provide a thermal performance detection device, as Figures 1 to 3 shown, including a detection box 1, a heat dissipation component 2, a plugging plate 3, a lifting mechanism 4, and a sealing component 5; The detection box 1 has a detection cavity 111, and the heat dissipation component 2 is connected to the detection box 1 and has a heat dissipation cavity 211 communicating with the detection cavity 111; The plugging plate 3 is slidably matched with the detection box 1, and the lifting mechanism 4 is connected between the detection box 1 and the plugging plate 3. The lifting mechanism 4 is used to drive the plugging plate 3 to block or release the opening of the heat dissipation cavity 211 close to the detection cavity 111; The sealing component 5 is connected between the plugging plate 3 and the heat dissipation component 2 to seal the gap between the plugging plate 3 and the heat dissipation component 2 when the plugging plate 3 blocks the opening.

[0024] When it is necessary to quickly heat up the detection cavity, as Figure 1As shown, the lifting mechanism 4 can drive the plugging plate 3 to plug the opening of the heat dissipation cavity 211 close to the detection cavity 111. At the same time, the sealing component 5 seals the gap between the plugging plate 3 and the heat dissipation component 2, reducing heat loss, accelerating the temperature rise of the detection cavity 111, achieving the required high-temperature detection conditions in a short time, improving the detection efficiency, and reducing the temperature fluctuation in the detection cavity during the temperature rise process.

[0025] When heat dissipation is required, the lifting mechanism 4 can drive the plugging plate 3 to release the above-mentioned opening, open the heat dissipation cavity 211, and realize the accurate performance detection of the product to be tested 7 in different temperature environments.

[0026] It should be noted that any structure that can drive the plugging plate 3 to plug or release the above-mentioned opening can be the lifting mechanism 4 mentioned in the above embodiment. For example, the lifting mechanism 4 can be a structure that makes a linear motion such as a pneumatic cylinder, a hydraulic cylinder, or a linear motor, or can include a screw, or a structure that includes the cooperation of a gear and a rack, converting the rotation of the power source into a linear motion.

[0027] In an alternative embodiment, as Figure 1 shown, the lifting mechanism 4 includes a first driver 41 and a first screw 42. The first driver 41 is installed on the detection box 1. One end of the first screw 42 is rotatably connected to the detection box 1 through a bearing, and the other end is connected to the first driver 41. The plugging plate 3 is in threaded cooperation with the first screw 42.

[0028] In use, the first driver 41 can drive the first screw 42 to rotate. Since the plugging plate 3 is slidably engaged with the detection box 1, the first screw 42 can drive the plugging plate 3 to lift and lower, so that the plugging plate 3 can plug or release the above-mentioned opening.

[0029] The above-mentioned lifting mechanism has a simple structure. Since the plugging plate 3 is in threaded cooperation with the first screw 42, it is easier to ensure the position accuracy of the plugging plate 3 after lifting and lowering.

[0030] Among them, the first driver 41 can be, but is not limited to, a motor. The motor can be arranged at the top of the outer surface of the detection box 1. The first screw 42 is rotatably connected inside the detection box 1 and extends along the height direction of the detection box 1. The plugging plate 3 is slidably engaged with the detection box 1 along the height direction of the detection box 1.

[0031] Guide rods extending along the height direction of the detection box 1 can be provided inside the detection box 1. Specifically, the plugging plate 3 can be slidably engaged with two guide rods to ensure that the plugging plate 3 can stably move along the height direction of the detection box 1.

[0032] As Figure 2 shown, a temperature sensor 32 can be provided on the surface of the plugging plate 3 facing the detection cavity 111. The temperature sensor 32 can monitor the temperature inside the detection cavity 111 in real time, and realize the accurate performance detection of the product to be tested 7 in different temperature environments.

[0033] In an alternative embodiment, as Figure 2 shown, the sealing assembly 5 includes a telescopic frame 51, an elastic member 52, an adsorption frame 53, and an electromagnetic member 54; a groove 31 is recessed in the surface of the plugging plate 3 facing the heat dissipation cavity 211; one ends of the telescopic frame 51 and the elastic member 52 are both connected to the bottom of the groove 31, and the other ends are both connected to the adsorption frame 53. The telescopic frame 51 is telescopic along the depth direction of the groove 31, and the elastic member 52 is used to limit the adsorption frame 53 in the groove 31; the electromagnetic member 54 is installed inside the heat dissipation cavity 211, and the electromagnetic member 54 is configured to adsorb the adsorption frame 53 by overcoming the elastic force of the elastic member 52 in the energized state, and cancel the adsorption of the adsorption frame 53 in the non-energized state.

[0034] In the case where the sealing assembly 5 is not provided, since the plugging plate 3 is slidably engaged with the detection box 1 along the height direction of the detection box 1, the plugging plate 3 cannot apply a pre-pressure to the heat dissipation assembly 2 when plugging the opening of the heat dissipation cavity 211 close to the detection cavity 111 to ensure the sealing between the two.

[0035] In the above embodiment, after the plugging plate 3 plugs the opening of the heat dissipation cavity 211 close to the detection cavity 111, the electromagnetic member 54 can be controlled to be energized. The electromagnetic member 54 adsorbs the adsorption frame 53 by overcoming the elastic force of the elastic member 52. At the same time, the telescopic frame 51 extends out of the groove 31. The electromagnetic member 54, the adsorption frame 53, and the telescopic frame 51 can seal the gap between the plugging plate 3 and the heat dissipation assembly 2, playing a role in isolating the detection cavity 111 and the heat dissipation cavity 211. When heat dissipation is required, the electromagnetic member 54 can be controlled to be de-energized, and the adsorption frame 53 retracts into the groove 31 under the drive of the elastic member 52. At the same time, the telescopic frame 51 is entirely located in the groove 31, so as not to hinder the lifting of the plugging plate 3.

[0036] The above sealing assembly 5 has a simple structure. By energizing and de-energizing the electromagnetic member 54, the sealing and unsealing of the gap between the plugging plate 3 and the heat dissipation assembly 2 can be realized, which is convenient for personnel to operate.

[0037] The energization and de-energization of the electromagnetic member 54 can be controlled by personnel pressing a control button, and its control principle is prior art and will not be elaborated in detail here to save space.

[0038] Specifically, as Figure 3 shown, the telescopic frame 51 may include an inner frame 511 and an outer frame 512 sleeved outside the inner frame 511. One ends of the inner frame 511 and the outer frame 512 are both fixedly connected to the bottom of the groove 31, and the other ends are both fixedly connected to the adsorption frame 53. The elastic member 52 is located between the inner frame 511 and the outer frame 512.

[0039] The inner frame 511 and the outer frame 512 can be made of rubber frames. The rubber frames have a certain elasticity and can undergo a certain amount of deformation to accommodate the insertion and extraction of the adsorption frame 53 into and out of the groove 31. The inner frame 511 and the outer frame 512 can also be made of bellows, and the corrugated structure is used to accommodate the insertion and extraction of the adsorption frame 53 into and out of the groove 31.

[0040] Both the inner frame 511 and the outer frame 512 can adopt a frame structure. Correspondingly, the adsorption frame 53 and the electromagnetic component 54 can also adopt a frame structure, so as to achieve a full seal of the gap between the plugging plate 3 and the heat dissipation component 2.

[0041] When the opening of the heat dissipation cavity 211 close to the detection cavity 111 is rectangular, the inner frame 511, the outer frame 512, the adsorption frame 53 and the electromagnetic component 54 are all rectangular frame structures.

[0042] In an alternative embodiment, as Figure 4 shown, the adsorption frame 53 includes a metal frame 531 and an elastic pad 532. One side of the metal frame 531 is connected to the telescopic frame 51 and the elastic member 52, the elastic pad 532 is connected to the metal frame 531, and the elastic pad 532 protrudes from the side of the metal frame 531 facing away from the telescopic frame 51 and the elastic member 52.

[0043] When the electromagnetic component 54 is energized, the electromagnetic component 54 overcomes the elastic force of the elastic member 52 to adsorb the metal frame 531. Since the elastic pad 532 protrudes from the side of the metal frame 531 facing away from the telescopic frame 51 and the elastic member 52, the elastic pad 532 will preferentially contact the electromagnetic component 54 and be compressed under the magnetic force until the metal frame 531 is in force balance. At this time, the metal frame 531 contacts the electromagnetic component 54, or there is still a certain distance between the metal frame 531 and the electromagnetic component 54.

[0044] Compared with the above-mentioned embodiment that realizes sealing only through the contact between the metal frame 531 and the electromagnetic component 54, the above-mentioned embodiment has a better sealing effect.

[0045] Among them, the material of the elastic pad 532 can be rubber or soft plastic, etc.

[0046] In an alternative embodiment, as Figure 2 shown, the heat dissipation component 2 includes a frame body 21, a grid plate 22, a mesh plate 23 and a heat dissipation member 24. The frame body 21 is connected to the detection box 1. The frame body 21 has a heat dissipation cavity 211. Both the grid plate 22 and the mesh plate 23 are installed in the heat dissipation cavity 211. The grid plate 22 is arranged closer to the detection cavity 111 than the mesh plate 23. An electromagnetic component 54 is provided on the surface of the grid plate 22 facing the detection cavity 111. The heat dissipation member 24 is located between the grid plate 22 and the mesh plate 23.

[0047] During use, external gas can enter the detection chamber 111 successively through the mesh plate 23, the heat dissipation component 24, and the grid plate 22. The gas in the detection chamber 111 can also be discharged through the grid plate 22, the heat dissipation component 24, and the mesh plate 23 successively to achieve the cooling of the detection chamber 111. When it is necessary to seal the heat dissipation chamber 211, the adsorption frame 53 abuts against the electromagnetic component 54 on the grid plate 22 to achieve the sealing effect.

[0048] Among them, two heat dissipation assemblies 2 can be configured. The two heat dissipation assemblies 2 are respectively arranged on both sides of the detection box 1, and the heat dissipation component 24 can be a fan.

[0049] When it is necessary to cool the detection box 1, the heat dissipation component 24 on one side can allow external air to enter the detection chamber 111 through the heat dissipation chamber 211, and the heat dissipation component 24 on the other side can allow the air in the detection chamber 111 to be discharged to the outside through the heat dissipation chamber 211, accelerating the air flow in the detection chamber 111, accelerating the cooling rate of the product under test 7, and shortening the detection cycle.

[0050] Among them, the product under test can be an energy storage battery.

[0051] In an alternative embodiment, such as Figure 5 and Figure 6 shown, the detection box 1 includes a box body 11, a door body 12, a base 13, and an adjustment mechanism 14; the box body 11 has a detection chamber 111, and the door body 12 is movably connected to the box body 11 to open and close the inlet and outlet of the detection chamber 111; the adjustment mechanism 14 is connected between the box body 11 and the base 13, and the adjustment mechanism 14 is configured to drive the base 13 in and out of the inlet and outlet of the detection chamber 111.

[0052] In the initial state, the base 13 is located outside the box body 11, which is convenient for placing the product under test 7. During detection, the adjustment mechanism 14 sends the product under test 7 into the box body 11, which is convenient for placing the product under test 7 and expands the operation space for personnel.

[0053] It should be noted that any structure that can drive the base 13 in and out of the detection chamber 111 can be the adjustment mechanism 14 mentioned in the above embodiments. The optional structures of the adjustment mechanism 14 are similar to the optional structures of the lifting mechanism 4, and for the sake of saving space, they will not be listed one by one here.

[0054] In an alternative embodiment, such as Figure 5 and Figure 6As shown, the adjusting mechanism 14 includes a third driver 141, a synchronous belt 142, a driving wheel, a driven wheel 143, a third screw 144 and a fourth screw 145. The third driver 141 is installed on the outside of the box body 11 through a motor frame, the driving wheel is connected to the power output end of the third driver 141, the driven wheel 143 is connected to the driving wheel through the synchronous belt 142, the third screw 144 is rotationally matched with the box body 11 and is fixedly connected to the power output end of the third driver 141, the fourth screw 145 is rotationally matched with the box body 11 and is fixedly connected to the driven wheel 143, the extension directions of the third screw 144 and the fourth screw 145 are perpendicular to the inlet and outlet, and the base 13 is threadedly matched with the third screw 144 and the fourth screw 145.

[0055] During the test, the third driver 141 drives the third screw 144 and the driving wheel to rotate, and the driven wheel 143 is synchronously rotated through the transmission of the synchronous belt 142, and the base 13 can move along the axial direction of the third screw 144 and the fourth screw 145 to send the product 7 to be tested into the box 11, which simplifies the operation process and improves the test efficiency. The principle of sending the product 7 to be tested from the box 11 is the same, and it will not be described in detail here to save space.

[0056] The third driver 141 may be, but is not limited to, a motor.

[0057] Specifically, Figure 6 As shown, the base 13 includes an inverted U-shaped plate and two L-shaped plates, the two L-shaped plates are threadedly matched with the third screw 144 and the fourth screw 145 respectively, one end of the inverted U-shaped plate is fixedly connected to one of the L-shaped plates, and the other end is fixedly connected to the other L-shaped plate.

[0058] In an optional embodiment, if Figure 6 As shown, the base 13 is connected to a second driver 15 and a placement seat 16, the second driver 15 is installed below the inverted U-shaped plate, the placement seat 16 is rotatably connected to the top of the inverted U-shaped plate, and the second driver 15 is connected to the placement seat 16 to drive the placement seat 16 to rotate with the vertical direction as the axis.

[0059] In the above embodiment, the bottom surface of the inverted U-shaped plate is equipped with a second driver 15, and the power output end of the second driver 15 is connected to the placement seat 16, which can drive the placement seat 16 and the product to be tested 7 to rotate with the vertical direction as the axis. During the detection process, the product to be tested 7 is driven to rotate by the second driver 15, so that the product to be tested 7 can be evenly heated, ensuring the accuracy of the detection result.

[0060] The second driver 15 may be, but is not limited to, a motor.

[0061] In an optional embodiment, if Figure 6 and Figure 7As shown, a frame 113 is fixedly installed on the rear inner wall of the box body 11, and an electric heating tube 114 is fixedly installed on the inner wall of the frame 113. A protective net plate 115 is fixedly installed inside the frame 113 to protect the electric heating tube 114 inside the frame 113.

[0062] In an alternative embodiment, as Figure 8 and Figure 9 shown, a first clamping plate 17 and a second clamping plate 18 are slidably connected to the placing seat 16. The placing seat 16 is rotatably connected to a second screw rod 19. The second screw rod 19 has a first thread that is in threaded cooperation with the first clamping plate 17 and a second thread that is in threaded cooperation with the second clamping plate 18. The helix direction of the first thread is opposite to that of the second thread.

[0063] When installing the product 7 to be tested, the second screw rod 19 can be rotated. Since the helix direction of the first thread is opposite to that of the second thread, and both the first clamping plate 17 and the second clamping plate 18 are slidably engaged with the placing seat 16, the first clamping plate 17 and the second clamping plate 18 will approach or move away from each other during the rotation of the second screw rod 19, so as to adjust the distance between the first clamping plate 17 and the second clamping plate 18, and realize the clamping and release of the product 7 to be tested.

[0064] The above embodiment can adapt to products 7 to be tested of different sizes, and ensure that the products 7 to be tested will not shift during the detection process, improving the stability and accuracy of the detection.

[0065] For the convenience of personnel operation, a knob can be provided at one end of the second screw rod 19.

[0066] In addition, notch openings are formed on the opposite surfaces of the first clamping plate 17 and the second clamping plate 18, and rubber pads are fixedly installed on the inner surfaces of the notch openings. The rubber pads are made of elastic rubber to protect the product 7 to be tested.

[0067] A chute 161 can be recessed on the top surface of the placing seat 16. Both the first clamping plate 17 and the second clamping plate 18 are slidably engaged with the chute 161. The second screw rod 19 is rotatably connected inside the chute 161.

[0068] The cross-section of the above chute 161 can be rectangular or semi-circular, etc. When the cross-section of the chute 161 is semi-circular, both the first clamping plate 17 and the second clamping plate 18 are in contact with the top surface of the placing seat 16.

[0069] In an alternative embodiment, as Figure 10 and Figure 11 shown, the detection box 1 includes a box body 11 and a door body 12. The box body 11 has a detection cavity 111. A through groove 112 is formed on the side wall of the box body 11. The door body 12 passes through the through groove 112 and is slidably engaged with the through groove 112 to open and close the inlet and outlet of the detection cavity 111.

[0070] The above-described embodiment uses a push-pull type door body 12, which can close the inlet and outlet during detection to seal the interior, facilitating rapid heating and temperature maintenance inside the detection chamber 111. At the same time, when heat dissipation is required, the door body 12 can be opened to further accelerate the heat dissipation efficiency of the product 7 to be tested, improving the flexibility and efficiency of detection.

[0071] In an alternative embodiment, to ensure the sealing performance between the door body 12 and the box body 11 during detection, an elastic sealing sheet 6 is provided at the inlet and outlet. One side of the elastic sealing sheet 6 is connected to the box body 11, and the other side is configured to press against the inner wall and / or outer wall of the door body 12 when the door body 12 closes the inlet and outlet.

[0072] The provision of the elastic sealing sheet 6 enables better sealing between the box body 11 and the door body 12, thereby preventing the air inside the box body 11 from leaking out or external air from entering the box body 11.

[0073] As Figure 12 shown, one elastic sealing sheet 6 is connected to the outer wall of the box body 11 corresponding to the inlet and outlet, and another elastic sealing sheet 6 is connected to the outer wall of the box body 11 corresponding to the inlet and outlet. The middle parts of the two elastic sealing sheets 6 are close to each other and bent to press against the inner wall 121 and outer wall 122 of the door body to achieve a double-layer sealing effect; the free ends of the two elastic sealing sheets 6 are far from each other to facilitate the entry of the door body 12 between the two elastic sealing sheets 6.

[0074] As Figure 1 shown, a battery performance detector 8 is fixedly installed on the top surface of the box body 11 for detecting the charge and discharge performance of the energy storage battery.

[0075] The battery performance detector 8 can be an existing detector, and its structure will not be described in detail here to save space.

[0076] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
