Description

Technical Field

[0001] This utility model belongs to the field of battery technology, and specifically relates to an integrated battery temperature control device. Background Technology

[0002] Integrated batteries, as a technical solution that deeply integrates batteries with other components of a device, are designed to achieve more efficient, lighter, and safer battery systems. During the production and processing of integrated batteries, it is necessary to examine their performance in high and low temperature environments to ensure the quality of the integrated batteries leaving the factory.

[0003] Conventional integrated battery temperature control devices typically employ static temperature control methods, such as directly regulating the temperature of the integrated battery through a constant temperature chamber or heating / cooling modules. Some even use a method of stacking multiple integrated batteries sequentially. However, due to the single airflow path design of traditional devices, uneven heating or cooling of the integrated battery sidewalls can occur. This is especially problematic in large batteries or high-power testing scenarios, where localized temperature differences can affect the accuracy of test results and even cause abnormal battery performance. Furthermore, some forced convection temperature control devices directly impact the battery surface with airflow from one side. This can damage the surface coating of the integrated battery and cause temperature response lag or localized overheating or overcooling due to asymmetrical airflow distribution. This fails to guarantee the synchronicity and stability of the integrated battery sidewall temperature control, thus affecting the accuracy of battery test data.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

The output ends of both the first pipe and the second pipe are connected to the test cavity from the upper side of the housing. The outer walls of both the first pipe and the second pipe are connected to the output ends of the heater and the cooler. A telescopic cylinder is installed on the side wall of the chamber. The output end of the telescopic cylinder extends into the test cavity and is connected to the clamping assembly. The clamping assembly is located directly below the output ends of the first and second pipes, and the output ends of the first and second pipes are arranged symmetrically about the clamping assembly.

[0006] Furthermore, the clamping assembly includes a support plate, a drive plate, and clamping rods; The test cavity has a bearing plate on the lower inner wall, and a drive plate is slidably mounted on the bearing plate. The drive plate extends along the first direction and is coaxially arranged with the output end of the telescopic cylinder. The two opposing side walls of the drive plate in the second direction are provided with racks, and the first direction and the second direction are arranged perpendicularly.

[0007] Furthermore, clamping pads are provided on the second end sidewalls of both clamping rods.

[0008] Furthermore, the inner wall of the housing is provided with coaxially arranged circular and square sliding grooves. The inner wall of the circular sliding groove is slidably connected to the outer wall of the extension end of the telescopic cylinder, and one end of the drive plate is inserted into the square sliding groove to form a sliding sleeve with the square sliding groove.

[0009] Furthermore, the circular groove runs through the side wall of the housing, while the axial length of the square groove is less than that of the circular groove.

[0010] Furthermore, the exhaust assembly includes an exhaust box and an air pump installed on the outer wall of the housing. The exhaust box has a buffer cavity inside. The air pump is located on the first side wall of the exhaust box. The output end of the air pump is connected to the input end of the first pipe and the second pipe.

A telescopic cylinder drives a clamping assembly to hold the battery, maintaining it in a vertical and centered position. An exhaust assembly draws in external air, which flows through a first and second pipe into the test cavity of the housing. Simultaneously, depending on cooling or heating requirements, a heater and a cooler work together to heat or cool the air flowing within the first and second pipes, thereby controlling the temperature within the test cavity. Furthermore, the first and second pipes are symmetrically arranged about the clamping assembly, ensuring that the gas flow rate and volume from their output ends are synchronized. This synchronizes the airflow's effect on battery temperature control and prevents direct impact on the battery's sidewalls, guaranteeing the uniformity and stability of temperature fluctuations on the battery's sidewalls.

[0020] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides an integrated battery temperature control device. Figure 1 A schematic diagram of the integrated battery temperature control device in an embodiment of this utility model is shown. Figure 1 ,refer to Figures 1 to 3 The integrated battery temperature control device includes: a housing 1, a heater 2, and a cooler 3. The housing 1 has a test cavity inside. A ventilation assembly is installed on the side wall of the housing 1. The output end of the ventilation assembly is connected to the input end of the first pipe 4 and the second pipe 5. The output ends of the first pipe 4 and the second pipe 5 are both connected to the test cavity from the upper side of the housing 1. The outer walls of the first pipe 4 and the second pipe 5 are both connected to the output ends of the heater 2 and the cooler 3. A telescopic cylinder 6 is installed on the side wall of the housing 1. The output end of the telescopic cylinder 6 extends to the test cavity and is connected to the clamping assembly. The clamping assembly is located directly below the output ends of the first pipe 4 and the second pipe 5, and the output ends of the first pipe 4 and the second pipe 5 are arranged symmetrically about the clamping assembly.

[0023] The integrated battery temperature control device of this application, in actual use, first places the battery to be tested into the test cavity, and drives the clamping assembly to clamp the battery through the telescopic cylinder 6, thereby keeping the battery in a vertical and centered position, and ensuring that the distance between the battery and the output ends of the first pipe 4 and the second pipe 5 is consistent; external air is drawn in by the exhaust assembly, and then the air drawn in by the exhaust assembly is delivered to the first pipe 4 and the second pipe 5, and then flows into the test cavity of the housing 1 through the first pipe 4 and the second pipe 5; at the same time, according to the cooling or heating requirements, the air flowing in the first pipe 4 and the second pipe 5 is heated or cooled by the cooperation of the heater 2 and the cooler 3, thereby realizing the temperature control of the test cavity; in this embodiment, the first pipe 4 and the second pipe 5 are symmetrically arranged about the clamping assembly, and the gas flow rate and volume delivered from the output ends of the first pipe 4 and the second pipe 5 can be kept synchronized, so that the airflow output from the first pipe 4 and the second pipe 5 keeps the temperature control of the battery synchronized, and avoids the airflow directly impacting the front of the battery sidewall, ensuring the uniformity and stability of the temperature change of the battery sidewall.

[0024] exist Figure 4 In the illustrated embodiment, the clamping assembly includes a support plate 7, a drive plate 8, and a clamping rod 9; The test cavity has a bearing plate 7 on its lower inner wall, and a drive plate 8 is slidably mounted on the bearing plate 7. The drive plate 8 extends along the first direction and is coaxially arranged with the output end of the telescopic cylinder 6. The two opposing sidewalls of the drive plate 8 in the second direction are provided with racks. The first direction and the second direction are arranged perpendicularly. The bearing plate 7 is provided with two rotating shafts 10, which are located on both sides of the drive plate 8 in the second direction. The outer wall of the first end of the clamping rod 9 is provided with ring teeth. The first end of the two clamping rods 9 is rotatably connected to the two rotating shafts 10, and the ring teeth of the first end of the two clamping rods 9 are respectively engaged with the rack of the side wall of the drive plate 8.

[0025] During use, the output end of the telescopic cylinder 6 drives the drive plate 8 to reciprocate along the first direction. The rack on the side wall of the drive plate 8 drives the clamping rod 9 to rotate in a circle around the corresponding pivot 10. Specifically, when the telescopic cylinder 6 extends to its maximum length, the drive plate 8 drives the two clamping rods 9 to expand outward, and the two clamping rods 9 are coaxially arranged in the second direction. When the telescopic cylinder 6 retracts to its shortest length, the drive plate 8 drives the two clamping rods 9 to retract inward, and the two clamping rods 9 are parallel in the first direction, forming a space for clamping the battery between the two clamping rods 9.

[0026] Furthermore, the support plate 7 supports the drive plate 8 and the clamping rod 9, preventing the drive plate 8 from being suspended and improving the stability of the drive plate 8's transmission connection to the clamping rod 9. In practical applications, the thickness of the support plate 7 can be adjusted according to requirements, and the distance between the two clamping rods 9 can be adjusted accordingly based on different battery thicknesses to meet the testing requirements of batteries with different thicknesses and heights.

[0027] In this embodiment, the second end sidewalls of both clamping rods 9 are provided with clamping pads 11. When the telescopic cylinder 6 retracts to its shortest length, the drive plate 8 drives the two clamping rods 9 to a retracted state. The two clamping rods 9 are arranged in parallel in the first direction, and the clamping pads 11 of the two clamping rods 9 are arranged opposite to each other. The bearing surface of the clamping pad 11 is used to form a fit with the sidewall of the battery. The clamping pad 11 avoids hard contact between the sidewall of the clamping rod 9 and the sidewall of the battery, thereby protecting the sidewall of the battery.

[0028] exist Figure 5 In the example shown, the inner wall of the housing 1 is provided with a circular groove 12 and a square groove 13 arranged coaxially. The inner wall of the circular groove 12 is slidably connected to the outer wall of the extension end of the telescopic cylinder 6. One end of the drive plate 8 is inserted into the square groove 13 and forms a sliding sleeve with the square groove 13.

[0029] The position of the extension end of the telescopic cylinder 6 is limited by the circular slide groove 12, and the position of the drive plate 8 is limited by the square slide groove 13, so as to ensure the stability of the extension end of the telescopic cylinder 6 and the drive plate 8 and prevent the drive plate 8 from rotating circumferentially.

[0030] Furthermore, in this embodiment, the circular slide 12 penetrates the side wall of the housing 1, and the axial length of the square slide 13 is less than the axial length of the circular slide 12, thereby limiting the position of the drive plate 8 by the square slide 13 in the first direction.

[0031] refer to Figure 2 The exhaust assembly includes an exhaust box 14 and an air pump 15 installed on the outer wall of the housing 1. The exhaust box 14 has a buffer cavity inside. The first side wall of the exhaust box 14 is provided with the air pump 15. The output end of the air pump 15 is connected to the input end of the first pipe 4 and the second pipe 5. The input end of the air pump 15 is connected to the buffer cavity. The side wall of the exhaust box 14 adjacent to the first side wall has several through holes that connect to the buffer cavity.

[0032] The air pump 15 draws outside air into the exhaust box 14, and then delivers it to the test cavity through the first pipe 4 and the second pipe 5. During this process, the airflow first passes through the through hole to initially block debris in the external environment. Since the through hole is located on the side wall of the exhaust box 14 adjacent to the first side wall, the airflow inside the exhaust box 14 changes direction, thus buffering the airflow and ensuring the stability of the airflow entering the test cavity.

[0033] Furthermore, to further improve the cleanliness of the airflow entering the test cavity and prevent impurities from entering the test cavity, each of the several through holes is embedded with a filter screen to filter the airflow. Figure 2 In the example shown, several through holes are arranged radially from the center.

[0034] In this embodiment, a controller 16 is also provided on the outer wall of the housing 1. The controller 16 is electrically connected to the air pump 15, the heater 2, the cooler 3, and the telescopic cylinder 6.

[0035] In addition, it includes a temperature detector 17 disposed inside the inner wall of the test cavity, the temperature detector 17 being electrically connected to the controller 16.

[0036] The controller 16 adjusts the air pump 15, heater 2, cooler 3 and telescopic cylinder 6 according to the test requirements and the data from the temperature detector 17, so as to facilitate precise temperature control.

[0037] During use, a telescopic cylinder 6 is installed on the first side wall of the housing 1. The side wall opposite to the first side wall of the housing 1 is a rotating door 18. The rotating door 18 is rotatably connected to the housing 1, and a handle 19 is installed on the outer wall of the rotating door 18 to facilitate the pulling of the battery. The rotating door 18 and the clamping assembly are arranged opposite to each other to facilitate the placement of the battery in the middle position.
