Description

[0003] In the field of thermal performance detection of energy storage devices, existing detection equipment generally includes a box for accommodating the energy storage device, and a heat dissipation channel is provided on the box to dissipate heat inside the box during the detection process to prevent the temperature from being too high and affecting the detection results or damaging the equipment. However, this design has obvious deficiencies when it is necessary to quickly raise the temperature inside the box.

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.

[0043] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0044] 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 sealing plate 3, a lifting mechanism 4, and a sealing component 5;

[0045] 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;

[0046] The sealing plate 3 is slidably matched with the detection box 1, and the lifting mechanism 4 is connected between the detection box 1 and the sealing plate 3. The lifting mechanism 4 is used to drive the sealing plate 3 to block or release the opening of the heat dissipation cavity 211 close to the detection cavity 111;

[0047] The sealing component 5 is connected between the sealing plate 3 and the heat dissipation component 2 to seal the gap between the sealing plate 3 and the heat dissipation component 2 when the sealing plate 3 blocks the opening.

[0048] When it is necessary to quickly heat up the detection cavity, as Figure 1 shown, the lifting mechanism 4 can drive the sealing plate 3 to block 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 sealing plate 3 and the heat dissipation component 2, reducing heat loss, accelerating the heating 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 heating process.

[0049] When heat dissipation is required, the lifting mechanism 4 can drive the sealing plate 3 to release the above-mentioned opening, open the heat dissipation cavity 211, and realize the accurate performance detection of the product 7 to be tested in different temperature environments.

[0050] It should be noted that any structure capable of driving the sealing plate 3 to block 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, a linear motor, etc., or can include a screw rod, or a structure including the cooperation of a gear and a rack, converting the rotation of the power source into a linear motion.

[0051] In an alternative embodiment, as Figure 1 shown, the lifting mechanism 4 includes a first driver 41 and a first screw rod 42. The first driver 41 is installed on the detection box 1. One end of the first screw rod 42 is rotatably connected to the detection box 1 through a bearing, and the other end is connected to the first driver 41. The sealing plate 3 is in threaded cooperation with the first screw rod 42.

[0052] 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 move up and down, enabling the plugging plate 3 to plug or release the above-mentioned opening.

[0053] The above-mentioned lifting mechanism has a simple structure. Since the plugging plate 3 is in threaded engagement with the first screw 42, it is easier to ensure the position accuracy of the plugging plate 3 after lifting.

[0054] 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 to the inside of 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.

[0055] 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 the two guide rods to ensure that the plugging plate 3 can move stably along the height direction of the detection box 1.

[0056] 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, realizing precise performance detection of the product under test 7 in different temperature environments.

[0057] 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 on the surface of the plugging plate 3 facing the heat dissipation cavity 211; one end of the telescopic frame 51 and the elastic member 52 is connected to the bottom of the groove 31, and the other end is 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.

[0058] 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.

[0059] In the above embodiment, after the sealing plate 3 seals 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 overcomes the elastic force of the elastic member 52 to adsorb the adsorption frame 53. 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 sealing plate 3 and the heat dissipation component 2, so as to isolate 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, thus not hindering the lifting of the sealing plate 3.

[0060] The above-mentioned 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 sealing plate 3 and the heat dissipation component 2 can be realized, which is convenient for personnel to operate.

[0061] The energization and de-energization of the electromagnetic member 54 can be controlled by a person pressing a control button, and its control principle is prior art and will not be described in detail here to save space.

[0062] 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.

[0063] The inner frame 511 and the outer frame 512 can be made of rubber frames. The rubber frames have a certain elasticity and can deform to a certain extent to adapt to the insertion and extension 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 corrugated pipes, and the corrugated structure is used to adapt to the insertion and extension of the adsorption frame 53 into and out of the groove 31.

[0064] Both the inner frame 511 and the outer frame 512 can adopt a frame structure. Correspondingly, the adsorption frame 53 and the electromagnetic member 54 can also adopt a frame structure, so as to realize the full sealing of the gap between the sealing plate 3 and the heat dissipation component 2.

[0065] 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 member 54 are all rectangular frame structures.

[0066] 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, and 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.

[0067] When the electromagnetic component 54 is energized, the electromagnetic component 54 overcomes the elastic force of the elastic component 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 component 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.

[0068] Compared with the above-mentioned implementation method that realizes sealing only through the contact between the metal frame 531 and the electromagnetic component 54, it has a better sealing effect.

[0069] Among them, the material of the elastic pad 532 can be rubber, soft plastic, etc.

[0070] 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. The grid plate 22 and the mesh plate 23 are both 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.

[0071] During use, the external gas can enter the detection cavity 111 through the mesh plate 23, the heat dissipation member 24 and the grid plate 22 in sequence. The gas in the detection cavity 111 can also be discharged through the grid plate 22, the heat dissipation member 24 and the mesh plate 23 in sequence to achieve the cooling of the detection cavity 111. When it is necessary to seal the heat dissipation cavity 211, the adsorption frame 53 abuts against the electromagnetic component 54 on the grid plate 22 to achieve the sealing effect.

[0072] Among them, two heat dissipation components 2 can be configured. The two heat dissipation components 2 are respectively arranged on both sides of the detection box 1. The heat dissipation member 24 can be a fan.

[0073] When the detection box 1 needs to be cooled, the heat dissipation member 24 on one side can allow the external air to enter the detection cavity 111 through the heat dissipation cavity 211, and the heat dissipation member 24 on the other side can allow the air in the detection cavity 111 to be discharged to the outside through the heat dissipation cavity 211, accelerating the flow of air in the detection cavity 111, accelerating the cooling rate of the product under test 7, and shortening the detection cycle.

[0074] Among them, the product under test can be an energy storage battery.

[0075] In an alternative embodiment, as Figure 5 and Figure 6As 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 cavity 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 cavity 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 cavity 111.

[0076] In the initial state, the base 13 is located outside the box 11, which is convenient for placing the product to be tested 7. During testing, the adjustment mechanism 14 sends the product to be tested 7 into the box 11, which is convenient for placing the product to be tested 7 and expanding the operating space for personnel.

[0077] 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 embodiment. The optional structure of the adjustment mechanism 14 is similar to the optional structure of the lifting mechanism 4. To save space, no examples will be given here one by one.

[0078] In an optional embodiment, if Figure 5 and Figure 6 As 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 the motor frame, the driving wheel is connected to the power output end of the third driver 141, and the driven wheel 143 is connected to the driving wheel through the synchronous belt 142. The third screw 144 rotates with the box body 11 and is fixedly connected to the power output end of the third driver 141. The fourth screw 145 rotates 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 both perpendicular to the inlet and outlet, and the base 13 is threadedly engaged with the third screw 144 and the fourth screw 145.

[0079] During testing, third driver 141 drives third screw 144 and the driving wheel to rotate. Driven by timing belt 142, driven wheel 143 rotates synchronously. Base 13 moves axially along third screw 144 and fourth screw 145 to deliver product 7 to be tested into housing 11, simplifying the process and improving testing efficiency. The principle of delivering product 7 from housing 11 is similar and will not be detailed here to save space.

[0080] The third driver 141 may be, but is not limited to, a motor.

[0081] Specifically, if 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 engaged 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.

[0082] In an alternative embodiment, as Figure 6 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, and the placement seat 16 is rotatably connected above the inverted U-shaped plate. The second driver 15 is connected to the placement seat 16 to drive the placement seat 16 to rotate about the vertical axis.

[0083] In the above embodiment, the second driver 15 is installed on the bottom surface of the inverted U-shaped plate, 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 under test 7 to rotate about the vertical axis. During the detection process, the product under test 7 is driven to rotate by the second driver 15, which can make the product under test 7 uniformly heated and ensure the accuracy of the detection result.

[0084] Among them, the second driver 15 can be, but is not limited to, a motor.

[0085] In an alternative embodiment, as Figure 6 and Figure 7 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 mesh plate 115 is fixedly installed inside the frame 113 to protect the electric heating tube 114 inside the frame 113.

[0086] In an alternative embodiment, as Figure 8 and Figure 9 shown, the placement seat 16 is slidably connected with a first clamping plate 17 and a second clamping plate 18. The placement seat 16 is rotatably connected with a second screw rod 19. The second screw rod 19 has a first thread threadedly engaged with the first clamping plate 17 and a second thread threadedly engaged with the second clamping plate 18. The helix direction of the first thread is opposite to that of the second thread.

[0087] When installing the product under test 7, 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 placement 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 under test 7.

[0088] The above embodiment can adapt to products under test 7 of different sizes and ensure that the products under test 7 will not shift during the detection process, improving the stability and accuracy of the detection.

[0089] For the convenience of personnel operation, a knob can be provided at one end of the second screw rod 19.

[0090] In addition, notches are formed on the opposite surfaces of the first clamping plate 17 and the second clamping plate 18, and a rubber pad is fixedly installed on the inner surface of the notch. The rubber pad is made of elastic rubber and plays a protective role for the product 7 to be tested.

[0091] The top surface of the placement seat 16 may be recessed with a sliding groove 161. Both the first clamping plate 17 and the second clamping plate 18 are slidably engaged with the sliding groove 161, and the second screw 19 is rotatably connected within the sliding groove 161.

[0092] The cross-section of the above-mentioned sliding groove 161 may be rectangular or semi-circular, etc. When the cross-section of the sliding groove 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 placement seat 16.

[0093] 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, and 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.

[0094] The above-mentioned embodiment adopts a push-pull type door body 12, which can close the inlet and outlet during detection, seal the interior, facilitate the rapid heating and temperature maintenance inside the detection cavity 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.

[0095] 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.

[0096] The arrangement of the elastic sealing sheet 6 can make the box body 11 and the door body 12 have better sealing performance, thereby preventing the air inside the box body 11 from overflowing or the external air from entering the box body 11.

[0097] 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 the 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 door body 12 to enter between the two elastic sealing sheets 6.

[0098] As Figure 1As 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.

[0099] The battery performance detector 8 can be an existing detector, and its structure will not be described in detail here to save space.
