Description

Technical Field

[0001] The present invention relates to the field of detection technology, and specifically, it is an airtightness detection device for an automotive thermal management super water kettle. Background Art

[0002] A super water kettle integrates multiple components such as electronic water pumps, multi-way electronic water valves, and expansion super water kettles into a compact unit, thereby forming an integrated thermal management system to improve the overall efficiency and performance of the system. Since electric vehicles require a structurally compact heat pipe embedding system to manage the temperatures of battery packs, electric motors, and other electronic components, the super water kettle has great application prospects in new energy vehicles.

[0003] The super water kettle needs to be connected to various components, so airtightness is an important indicator reflecting its quality. The most commonly used existing super water kettles are as Figure 9 and Figure 10 shown. The lower part of the super water kettle has a square structure, and installation protrusions are provided on the outer side surface of its lower part. Two openings are provided at both the bottom and the top of the super water kettle, and several openings are provided on both side surfaces of the super water kettle. When performing airtightness detection on the super water kettle, most of its opening positions will be blocked, and whether it leaks is monitored by pressurizing the inside of the super water kettle.

[0004] The above-mentioned detection method for the airtightness of the super water kettle can only detect its airtightness in a static state. However, the super water kettle will be subjected to external forces such as extrusion or impact during actual use. Therefore, the above detection method cannot objectively reflect the airtightness of the super water kettle, which may cause potential liquid leakage hazards during actual use of the super water kettle. In addition, when the opening positions of the super water kettle are closed, the airtightness detection may be affected due to incomplete closure. At the same time, since the position of the super water kettle cannot be stably locked, the airtightness detection of the super water kettle is affected. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 , Figure 3 and Figure 4 , an automobile thermal management super kettle air tightness detection device, comprising a lower support plate 1, a detection platform 2 installed on the lower support plate 1, a positioning and blocking component installed on the detection platform 2, and a pressurized conveyor 3 installed at the external free end, the detection platform 2 is installed on the upper side of the lower support plate 1 through a support column 21, the positioning and blocking component comprises two pressing mechanisms 4 installed on the detection platform 2 symmetrically in the left and right and two sealing mechanisms 5 installed on the detection platform 2 symmetrically in the front and back, two circular holes 24 are opened in the middle of the detection platform 2, the coolant filling port at the bottom of the super kettle passes through the circular holes 24, and a pressing and blocking component 25 for sealing the coolant filling port at the bottom of the super kettle is installed on the lower side of the detection platform 2. The present invention can lock the super kettle, and close the opening positions of the bottom and the side, and then perform air tightness detection on the super kettle through the two openings at the top of the super kettle.

[0036] Specifically, first place the super kettle on the detection platform 2. The coolant filling port at the bottom of the super kettle passes through the circular hole 24 provided on the detection platform 2, and the position of the super kettle is locked by the clamping mechanism 4. At this time, the clamping and sealing member 25 can seal the coolant filling port at the bottom of the super kettle. Then, the opening on the side of the super kettle is sealed by the sealing mechanism 5. After that, the airtightness of the super kettle is detected through the opening at the top of the super kettle by the pressurization transfer machine 3.

[0037] Refer to Figure 1 , it should be noted that the working principle of the pressurization transfer machine 3 is as follows: There are two connecting pipes on the pressurization transfer machine 3. One connecting pipe is connected to the air compressor on the pressurization transfer machine 3 at the upper end, and the other connecting pipe is connected to the pressure gauge on the pressurization transfer machine 3 at the upper end. The lower ends of the two connecting pipes are respectively sleeved and locked at the two opening positions above the super kettle (the middle parts of the connecting pipes here are all hoses). Then, turn on the air compressor. The dial on the air compressor itself will display the current output air pressure, and then read the air pressure value of the pressure gauge. After standing for a preset time, comparing the output air pressure with the air pressure value of the pressure gauge can determine whether the airtightness of the super kettle meets the requirements; Since the above working principle of the pressurization transfer machine 3 belongs to the prior art, it will not be elaborated here too much.

[0038] As Figure 9 and Figure 10 shown, the lower part of the super kettle is a square structure, and there are mounting protrusions on its lower outer side. There are two openings at the bottom and top of the super kettle, and there are several openings on both sides of the super kettle.

[0039] Refer to Figure 5 , Figure 7 and Figure 8 , the clamping mechanism 4 includes a clamping adjustment column 41 slidably connected to the detection platform 2, a frame-shaped connecting frame 42 installed on the clamping adjustment column 41, and a clamping fitting plate 44 installed on the side of the frame-shaped connecting frame 42 away from the outer edge of the detection platform 2 through a clamping spring column 43. There is a limit sliding groove 22 on the detection platform 2 for the clamping adjustment column 41 to slide. The lower end of the clamping adjustment column 41 extends below the detection platform 2, and clamping adjustment members 26 arranged left and right are installed at the bottom of the detection platform 2. The clamping adjustment members 26 are used to synchronously adjust the positions of the two clamping mechanisms 4 towards or away from each other. The clamping mechanism 4 is used to lock the position of the super kettle by positioning and pressing the left and right ends of the super kettle.

[0040] Specifically, by controlling the clamping adjustment member 26 to drive the two clamping adjustment columns 41 to move towards each other, the two clamping and fitting plates 44 are synchronously fitted to the left and right end faces of the super water kettle. As the clamping adjustment member 26 continues to drive the clamping adjustment column 41 to move towards each other, at this time, the clamping spring column 43 can automatically expand and contract, so that the two clamping and fitting plates 44 are fitted to the left and right end faces of the super water kettle with a certain force. The present invention adopts this flexible extrusion and positioning method to prevent the super water kettle from being deformed due to rigid contact force.

[0041] Refer to Figure 5 , for example, the clamping adjustment member 26 is a bidirectional lead screw, and the threads at both ends of the bidirectional lead screw are respectively in threaded engagement with the lower ends of the clamping adjustment columns 41 at the corresponding positions. By manually rotating the bidirectional lead screw, the two clamping adjustment columns 41 can be driven to move towards or away from each other.

[0042] Refer to Figure 1 , Figure 2 and Figure 8 , since the coolant filling port of the super water kettle needs to be sealed and fitted with the clamping plugging member 25, the super water kettle needs to apply a downward pressing force to completely insert the clamping plugging member 25 into the coolant filling port of the super water kettle. Therefore, the present invention adopts the method of synchronously pressing the super water kettle downward when the clamping and fitting plates 44 lock the left and right end faces of the super water kettle, thereby increasing the locking efficiency of the super water kettle and improving the sealing effect of the coolant filling port at the bottom of the super water kettle. Vertical sliding grooves 45 are provided at both the front and rear ends of the clamping and fitting plate 44, and a downward pressing bracket 46 is distributed on both the front and rear sides of the clamping and fitting plate 44. The side of the downward pressing bracket 46 close to the clamping and fitting plate 44 is slidably connected in the vertical sliding groove 45, and a lower pressing plate 47 is installed at the bottom of the downward pressing bracket 46; one end of the downward pressing bracket 46 located in the vertical sliding groove 45 is installed on the side wall of the vertical sliding groove 45 through a lifting elastic member. A moving block 48 and an extrusion block 49 are respectively installed between the downward pressing bracket 46 and the frame-shaped connecting frame 42. The moving block 48 and the extrusion block 49 are in mutual inclined plane cooperation. When the extrusion block 49 moves towards the moving block 48, the moving block 48 drives the downward pressing bracket 46 to move downward.

[0043] Specifically, when the clamping and fitting plates 44 are fitted to the left and right end faces of the super water kettle, as the clamping adjustment columns 41 continue to move towards each other, the clamping spring columns 43 contract. At this time, the moving block 48 moves towards the moving block 48. Under the action of the mutual inclined plane cooperation between the moving block 48 and the extrusion block 49, the extrusion block 49 drives the downward pressing bracket 46 to move downward, and then the lower pressing plate 47 presses the super water kettle downward through the installation protrusion at the lower part of the super water kettle, so that the coolant filling port of the super water kettle and the clamping plugging member 25 are clamped tightly with each other.

[0044] Refer to Figure 3 and Figure 4, the clamping and plugging member 25 includes a T-shaped plate 251 installed on the lower side of the detection platform 2 and two sealing plugs 252 respectively installed at both ends of the T-shaped plate 251. The positions of the sealing plugs 252 correspond one-to-one with the positions of the coolant filling ports at the bottom of the super water kettle. When the sealing plugs 252 are inserted into the coolant filling ports at the bottom of the super water kettle, they can seal the super water kettle.

[0045] Refer to Figure 1 and Figure 6 , the sealing mechanism 5 includes a sealing adjustment column 51 slidably connected to the detection platform 2, a sealing support plate 52 installed on the sealing adjustment column 51, and a sealing fitting plate 54 installed on the side of the sealing support plate 52 away from the outer edge of the detection platform 2 through a sealing spring column 53. The sealing fitting plate 54 is used to block the opening position on the side of the super water kettle. A relief sliding groove 23 for the sealing adjustment column 51 to slide is provided on the detection platform 2. The lower end of the sealing adjustment column 51 extends below the detection platform 2. Sealing adjustment members 27 arranged front and back are installed at the bottom of the detection platform 2. The sealing adjustment members 27 are used to synchronously adjust the positions of the two sealing mechanisms 5 towards or away from each other. A pressing and plugging block corresponding one-to-one with the opening position on the side of the super water kettle is provided on the side of the sealing fitting plate 54. A pressing plate 55 is provided on the pressing and plugging block located in the middle of the sealing fitting plate 54. The sealing mechanism 5 is used to block the opening positions on the front and back sides of the super water kettle, so that the opening positions at the bottom and side of the super water kettle are both blocked and sealed. Furthermore, the air tightness of the super water kettle can be detected through the two openings at the upper part of the super water kettle.

[0046] Specifically, after the left and right positions of the super water kettle are positioned, the two sealing adjustment columns 51 are driven to move towards each other by the sealing adjustment members 27. The pressing and plugging blocks on the sealing fitting plate 54 are used to correspondingly block the opening positions on the side of the super water kettle. The pressing plate 55 is used to limit the blocking position of the pressing and plugging blocks to prevent the pressing and plugging blocks from being inserted too deep into the opening positions on the side of the super water kettle, thereby affecting the sealing performance of the super water kettle.

[0047] Refer to Figure 5 , exemplarily, the sealing adjustment member 27 is a double-acting cylinder. The front and back telescopic ends of the double-acting cylinder are respectively connected to the lower ends of the corresponding sealing adjustment columns 51. The elongation movement of the double-acting cylinder can drive the two sealing adjustment columns 51 to move away from each other, and vice versa for moving towards each other.

[0048] Refer to Figure 1 and Figure 6, since the pressure plug on the sealing and fitting plate 54 requires a certain pressure to be fully inserted into the opening position on the side of the super kettle, and the setting of the sealing spring column 53 will cause the pressure plug on the sealing and fitting plate 54 to gradually increase the pressure during the movement of the sealing adjustment column 51. When the pressure plug on the sealing and fitting plate 54 is fully inserted into the corresponding opening position of the super kettle, the pressing plate 55 will press against the side of the super kettle with a certain force, thereby causing inaccurate airtightness detection of the super kettle. Therefore, in the present invention, when the pressure plug on the sealing and fitting plate 54 is inserted into the opening position of the super kettle, no buffering force is required. Therefore, the present invention provides a pressure rod 56. The side of the sealing and fitting plate 54 close to the sealing support plate 52 is rotatably installed with the pressure rod 56. One end of the pressure rod 56 away from the sealing and fitting plate 54 slidably penetrates through the sealing support plate 52. The sealing support plate 52 is provided with a linear chute corresponding to the pressure rod 56. The outer side of the pressure rod 56 is provided with a linear slider, and the linear slider is arranged on the side of the sealing support plate 52 close to the sealing and fitting plate 54. The pressure rod 56 can prevent the distance between the sealing support plate 52 and the sealing and fitting plate 54 from changing when the pressure plug on the sealing and fitting plate 54 is inserted into the opening position on the side of the super kettle.

[0049] Specifically, before the two sealing adjustment columns 51 move towards each other, by rotating the pressure rod 56, the linear slider on the pressure rod 56 is misaligned with the linear chute on the sealing support plate 52. At this time, the relative position between the sealing support plate 52 and the sealing and fitting plate 54 will not change. After the pressure plug on the sealing and fitting plate 54 is inserted into the opening position on the side of the super kettle, rotate the pressure rod 56 so that the linear slider on the pressure rod 56 is aligned with the linear chute on the sealing support plate 52.

[0050] Refer to Figure 5 , the support column 21 is an elastic telescopic structure. A vibration motor 28 is arranged at the bottom of the detection platform 2. Vibration by the vibration motor 28 can drive the detection platform 2 to vibrate, thereby causing the super kettle to vibrate. This method can simulate the small vibration generated by the motor during the driving process of the electric vehicle.

[0051] Refer to Figure 1 , a vibration mechanism 6 for knocking on the end face of the super kettle is installed on the side of the clamping and adjusting column 41. Through the vibration mechanism 6, the state when both ends of the super kettle are impacted by the internal liquid can be simulated.

[0052] In addition, the present invention uses multiple detection methods for the super kettle to increase the objectivity and accuracy of the airtightness evaluation of the super kettle.

[0053] Method 1: Detect the airtightness of the super kettle by the method of pressurization and static placement. After the openings at the bottom and side of the super kettle are sealed, the two connecting pipes on the pressurization transfer machine 3 are respectively sleeved and locked at the two opening positions above the super kettle. Then, turn on the air compressor. The dial on the air compressor itself will display the current output air pressure. Then read the air pressure value of the pressure gauge. After standing for a preset time, compare the final air pressure value of the pressure gauge with the output air pressure, and then analyze whether the airtightness of the super kettle meets the requirements. This method can obtain the airtightness of the super kettle in a static state.

[0054] Method 2: Observe the change of the air pressure value by increasing the pressure on the side of the super kettle. After the airtightness of the super kettle is detected by Method 1, there is no need to turn off the air compressor. At this time, control the sealing adjustment column 51 to continue to move towards each other. Since the one-way slider on the pressing rod 56 is facing the one-way chute on the sealing support plate 52 at this time, the sealing support plate 52 moves towards the super kettle, and at the same time the sealing spring column 53 contracts, so that the pressing plate 55 can apply pressure to the side of the super kettle. At this time, observe the change of the air pressure value of the pressure gauge. If the change of the air pressure value is within the preset change range, it means that the airtightness of the super kettle meets the requirements. This method can obtain the airtightness of the super kettle under the state of being pressured.

[0055] Method 3: Observe the change of the air pressure value by increasing the vibration force on the super kettle and increasing the pressure on its side. On the basis of Method 2, control the vibration motor 28 to vibrate. By observing the change of the air pressure value of the pressure gauge, if the change of the air pressure value is within the preset change range, it means that the airtightness of the super kettle meets the requirements. This method can obtain the airtightness of the super kettle under the dual states of being pressured and vibrated.

[0056] Method 4: Observe the change of the air pressure value by increasing the vibration force on the super kettle, increasing the pressure on its side, and increasing the hammering force on the end face. On the basis of Method 3, control the vibration mechanism 6 to strike the end face of the super kettle. By observing the change of the air pressure value of the pressure gauge, if the change of the air pressure value is within the preset change range, it means that the airtightness of the super kettle meets the requirements. This method can obtain the airtightness of the super kettle under the triple states of being pressured, vibrated, and impacted by liquid.

[0057] In addition, it can be understood that the airtightness detection of the above super kettle can combine the detection method of Method 1 with one or more methods of the super kettle being pressured, vibrated, and impacted by liquid for combined detection, and the combined detection methods are all within the protection scope of the present invention.

[0058] Refer to Figure 7 and Figure 8Exemplarily, the vibration mechanism 6 adopts the following structure, the vibration mechanism 6 includes a vibration bracket 61 installed on the clamping adjustment column 41, a knocking frame 62 with a side U-shaped structure is installed on the upper end of the vibration bracket 61 and the side away from the outer edge of the detection platform 2, a knocking block 63 is slidably connected in the knocking frame 62, one end of the knocking block 63 is installed in the knocking frame 62 through a return spring 64, and the other end of the knocking block 63 is facing the end face of the super kettle, a hammer linkage plate 65 is installed on the lower side of the knocking block 63, and a knocking transmission member is arranged on the side of the vibration bracket 61 and below the knocking frame 62; the knocking transmission member includes a transmission bracket 66 installed on the vibration bracket 61, A toggle plate 67 is installed in the transmission bracket 66 through a rotating shaft. The toggle plate 67 is provided with a toggle rod 68 which drives the return spring 64 to contract by hammering the linkage plate 65. One end of the rotating shaft on the toggle plate 67 is rotatably connected to the transmission bracket 66, and the other end of the rotating shaft on the toggle plate 67 is connected to the output shaft of the rotating motor 69 through a coupling. The rotating motor 69 is installed in the transmission bracket 66 through a motor seat. The vibration mechanism 6 is used to hammer the end face of the super kettle. Because when the electric car is bumped or shaken, the impact force of the liquid inside the super kettle on its end face is relatively large, so hammering the end face of the super kettle can simulate the situation where the end face is impacted by the internal liquid.

[0059] Specifically, by controlling the rotating motor 69 to rotate, the lever 68 on the dial 67 pushes the striking block 63 to the side away from the super kettle through the hammer linkage plate 65. At this time, the return spring 64 contracts and accumulates force. When the lever 68 is separated from the hammer linkage plate 65, the striking block 63 hammers the end face of the super kettle under the action of the return spring 64.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
