Description

Technical Field

[0001] The invention relates to the field of detection technology, in particular to an automobile thermal management super kettle air tightness detection device. Background Art

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

[0003] Super kettles need to connect multiple parts, so air tightness is an important indicator of their quality. The most commonly used super kettles are Fig. 9 and Fig.10 As shown, the lower part of the super kettle is a square structure, and a mounting protrusion is arranged on the outer side of the lower part. The bottom and the top of the super kettle are both provided with two openings, and the two sides of the super kettle are both provided with a plurality of openings. When the super kettle is tested for air tightness, most of its openings will be blocked, and the super kettle will be monitored for air leakage by pressurizing the inside of the super kettle.

[0004] The above-mentioned detection method for the air tightness of the super kettle can only detect the air tightness of the super kettle when it is in a static state. However, the super kettle will be subjected to external forces such as squeezing or impact during actual use. Therefore, the above-mentioned detection method cannot objectively reflect the air tightness of the super kettle, which may cause the hidden danger of liquid leakage in the actual use of the super kettle. In addition, closing the opening position of the super kettle will affect its air tightness detection due to incomplete closing. At the same time, the position of the super kettle cannot be stably locked, which affects the air tightness detection of the super kettle. 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 set on the detection platform 2, and the position of the super kettle is locked by the clamping mechanism 4. At this time, the clamping sealing member 25 can close the coolant filling port at the bottom of the super kettle, and then the opening on the side of the super kettle is closed by the sealing mechanism 5, and then the air tightness test is performed through the opening position at the top of the super kettle through the pressurized conveyor 3.

[0037] See also Figure 1 It should be noted that the working principle of the pressurized conveyor 3 is as follows: two connecting pipes are arranged on the pressurized conveyor 3, the upper end of one connecting pipe is connected to the air compressor on the pressurized conveyor 3, and the upper end of the other connecting pipe is connected to the pressure gauge on the pressurized conveyor 3, and the lower ends of the two connecting pipes are respectively mounted and locked in the two opening positions above the super kettle (the middle part of the connecting pipe here is a hose), and then the air compressor is turned on, the dial on the air compressor will display the current output air pressure, and then the air pressure value of the pressure gauge is read. After standing for a preset time, the output air pressure is compared with the air pressure value of the pressure gauge to determine whether the air tightness of the super kettle meets the requirements; since the working principle of the above-mentioned pressurized conveyor 3 belongs to the prior art, it will not be elaborated here.

[0038] like Fig. 9 and Fig.10 As shown, the lower part of the super kettle is a square structure, and a mounting protrusion is arranged on the lower outer side surface. The bottom and the top of the super kettle are both provided with two openings, and the two sides of the super kettle are both provided with a plurality of openings.

[0039] See also 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-type connecting frame 42 installed on the clamping adjustment column 41, and a clamping bonding plate 44 installed on the frame-type connecting frame 42 away from the outer edge of the detection platform 2 through a clamping elastic column 43. The detection platform 2 is provided with a limit slide 22 for the clamping adjustment column 41 to slide. The lower end of the clamping adjustment column 41 extends to the bottom of the detection platform 2. The bottom of the detection platform 2 is equipped with left and right clamping adjustment members 26, which are used to synchronously adjust the positions of the two clamping mechanisms 4 in opposite directions. 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, the two pressing adjustment columns 41 are driven to move toward each other by controlling the pressing adjustment member 26, so that the two pressing fitting plates 44 are synchronously fitted to the left and right end surfaces of the super kettle. As the pressing adjustment member 26 continues to drive the pressing adjustment columns 41 to move toward each other, the pressing elastic column 43 can automatically expand and contract, so that the two pressing fitting plates 44 are fitted to the left and right end surfaces of the super kettle with a certain force. The flexible extrusion positioning method adopted by the present invention can prevent the super kettle from being deformed due to the rigid contact force.

[0041] See also Figure 5 Exemplarily, the clamping adjustment member 26 is a bidirectional lead screw, and the threads at both ends of the bidirectional lead screw are respectively connected with the threads at 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 toward or away from each other.

[0042] See also Figure 1 , Figure 2 and Figure 8 Since the coolant filling port of the super kettle and the clamping sealing member 25 need to be sealed, the super kettle needs to apply a downward pressing force to make the clamping sealing member 25 completely inserted into the coolant filling port of the super kettle. Therefore, the present invention adopts a method of synchronously pressing the super kettle downward when the clamping laminating plate 44 locks the left and right end faces of the super kettle, thereby increasing the locking efficiency of the super kettle and increasing the sealing effect of the coolant filling port at the bottom of the super kettle. The front and rear ends of the clamping laminating plate 44 are both provided with vertical slide grooves 45. There is a downward pressing bracket 46 on both sides, and the side of the downward pressing bracket 46 close to the card pressing and fitting plate 44 is slidably connected in the vertical slide groove 45, and a downward 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 slide groove 45 is installed on the side wall of the vertical slide groove 45 through a lifting elastic member, and a moving block 48 and an extrusion block 49 are respectively installed between the downward pressing bracket 46 and the frame-type connecting frame 42, and the moving block 48 and the extrusion block 49 cooperate with each other on the inclined surfaces. When the extrusion block 49 moves in the direction of the moving block 48, the moving block 48 drives the downward pressing bracket 46 to move downward.

[0043] Specifically, after the pressing plate 44 is pressed against the left and right end faces of the super kettle, as the pressing adjustment column 41 continues to move toward each other, the pressing spring column 43 contracts, and the moving block 48 moves in the direction of the moving block 48. Under the cooperation of the mutual inclined surfaces of the moving block 48 and the extrusion block 49, the extrusion block 49 drives the pressing bracket 46 to move downward, and then the pressing plate 47 presses the super kettle downward through the mounting protrusion at the bottom of the super kettle, so that the coolant filling port of the super kettle and the pressing sealing member 25 are clamped with each other.

[0044] See also Figure 3 and Figure 4The compression 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 to the positions of the coolant filling ports at the bottom of the super kettle. The sealing plugs 252 are inserted into the coolant filling ports at the bottom of the super kettle to seal the super kettle.

[0045] See also 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 bonding plate 54 installed on the sealing support plate 52 away from the outer edge of the detection platform 2 through a sealing elastic column 53. The sealing bonding plate 54 is used to seal the opening position on the side of the super kettle. A makeshift slide 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 to the bottom of the detection platform 2. The bottom of the detection platform 2 is equipped with front and rear arranged sealing adjustment members 27. The sealing adjustment members 27 are used to synchronously adjust the two sealing mechanisms 5 to face each other or back to back. A pressing sealing plug corresponding to the opening position on the side of the super kettle is provided on the side of the sealing bonding plate 54, and a pressing plate 55 is provided on the pressing sealing plug located in the middle of the sealing bonding plate 54. The sealing mechanism 5 is used to seal the openings on the front and rear sides of the super kettle, so that the openings on the bottom and sides of the super kettle are sealed, and the air tightness of the super kettle can be tested through the two openings on the top of the super kettle.

[0046] Specifically, after the left and right positions of the super kettle are positioned, the two sealing adjustment columns 51 are driven by the sealing adjustment member 27 to move toward each other, and the pressure sealing plug on the sealing fitting plate 54 is used to perform corresponding sealing on the opening position on the side of the super kettle, and the pressing plate 55 is used to limit the sealing position of the pressure sealing plug to prevent the pressure sealing plug from being inserted too deeply into the opening position on the side of the super kettle, thereby affecting the sealing of the super kettle.

[0047] See also Figure 5 Exemplarily, the sealing adjustment member 27 is a bidirectional cylinder, and the front and rear telescopic ends of the bidirectional cylinder are respectively connected to the lower ends of the sealing adjustment columns 51 at corresponding positions. The elongation movement of the bidirectional cylinder can drive the two sealing adjustment columns 51 to move away from each other, and vice versa.

[0048] See also Figure 1 and Figure 6, since the pressure seal plug on the sealing fitting plate 54 needs a certain pressure to be fully inserted into the opening position on the side of the super kettle, and the setting of the sealing elastic column 53 will gradually increase the pressure of the pressure seal plug on the sealing fitting plate 54 during the movement of the sealing adjustment column 51, when the pressure seal plug on the sealing fitting plate 54 is fully inserted into the corresponding opening position of the super kettle, the pressing plate 55 will have a certain force against the side of the super kettle, thereby causing inaccurate airtightness detection of the super kettle, so the present invention requires a sealing When the pressure sealing plug on the sealing bonding plate 54 is inserted into the opening position of the super kettle, no buffering force is required. Therefore, the present invention is provided with a pressure rod 56. The side of the sealing bonding plate 54 close to the sealing support plate 52 is rotatably mounted with the pressure rod 56. One end of the pressure rod 56 away from the sealing bonding plate 54 slides through the sealing support plate 52. The sealing support plate 52 is provided with a straight groove at the position corresponding to the pressure rod 56. The outer side of the pressure rod 56 is provided with a straight slider, and the straight slider is provided on the side of the sealing support plate 52 close to the sealing bonding plate 54. The pressure rod 56 can prevent the spacing between the sealing support plate 52 and the sealing bonding plate 54 from changing when the pressure sealing plug on the sealing bonding 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 toward each other, the pressure rod 56 is rotated so that the straight-line slider on the pressure rod 56 is offset from the straight-line groove on the sealing support plate 52. At this time, the relative position of the sealing support plate 52 and the sealing bonding plate 54 will not change. When the pressure sealing plug on the sealing bonding plate 54 is inserted into the opening position on the side of the super kettle, the pressure rod 56 is rotated so that the straight-line slider on the pressure rod 56 is opposite to the straight-line groove on the sealing support plate 52.

[0050] See also Figure 5 The support column 21 is an elastic telescopic structure, and a vibration motor 28 is arranged at the bottom of the detection platform 2. The vibration of the vibration motor 28 can drive the detection platform 2 to vibrate, and then make the super kettle vibrate. This method can simulate the small vibration generated by the motor during the driving of the electric vehicle.

[0051] See also Figure 1 A vibration mechanism 6 for striking the end surface of the super kettle is installed on the side of the clamping adjustment column 41. The vibration mechanism 6 can simulate the state when the two ends of the super kettle are impacted by the internal liquid.

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

[0053] Method 1: Use pressurized static method to test the air tightness of the super kettle: After the bottom and side openings of the super kettle are sealed, the two connecting pipes on the pressurized conveyor 3 are respectively set and locked at the two openings above the super kettle, and then the air compressor is turned on. The dial on the air compressor will display the current output air pressure, and then read the air pressure value of the barometer. After the preset time is static, the final air pressure value of the barometer is compared with the output air pressure, and then the air tightness of the super kettle is analyzed to determine whether it meets the requirements. This method can obtain the air tightness of the super kettle in a static state.

[0054] Method 2: Observe the change of air pressure by increasing pressure on the side of the super kettle: Method 1: After the air tightness test of the super kettle is completed, there is no need to turn off the air compressor. At this time, the control seal adjustment column 51 continues to move toward each other. Since the straight slider on the pressure rod 56 is facing the straight groove on the seal support plate 52, the seal support plate 52 moves toward the super kettle, and the seal 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 barometer. If the air pressure value changes within the preset range, it means that the air tightness of the super kettle meets the requirements. This method can obtain the air tightness of the super kettle under pressure.

[0055] Method 3: Observe the change of air pressure by increasing the vibration force on the super kettle and increasing the pressure on its side: Based on method 2, the vibration motor 28 is controlled to vibrate, and the change of air pressure value of the barometer is observed. If the air pressure value change is within the preset range, it means that the air tightness of the super kettle meets the requirements. This method can obtain the air tightness of the super kettle under the dual state of pressure and vibration.

[0056] Method 4: observe the change of air pressure by increasing vibration force on the super kettle, increasing pressure on its side, and increasing hammer force on the end face: on the basis of method 3, control the vibration mechanism 6 to knock on the end face of the super kettle, and observe the change of air pressure value on the barometer. If the air pressure value change is within the preset range, it means that the air tightness of the super kettle meets the requirements. This method can obtain the air tightness of the super kettle under the triple state of pressure, vibration and liquid impact.

[0057] In addition, it can be understood that the air tightness test of the above-mentioned super kettle can combine the detection method of method one with one or more methods in which the super kettle is subjected to pressure, vibration and liquid impact force, and the combined detection methods are all within the protection scope of the present invention.

[0058] See also 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.
