Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Reference Figures 1 to 5According to a first aspect of the present invention, a battery tray airtightness testing inner sealing mechanism includes a positioning fixture, a driving device 100, a first transmission member 200, and a sealing assembly 300. The positioning fixture is used to fix a workpiece 400. The driving device 100 is disposed on the positioning fixture and includes a first driving component 110 and a second driving component 120. The first transmission member 200 is pulsatorically connected to the first driving component 110 and the second driving component 120. The sealing assembly 300 is disposed on the positioning fixture, located on one side of the driving device 100, and inside the workpiece 400. The sealing assembly 300 includes a base 310 and a sealing member 320. The sealing member 320 is slidably disposed on the base 310. The second driving component 120 can drive the first transmission member 200 to pulsatorically connect and disconnect from the sealing member 320. The first driving component 110 can drive the first transmission member 200 to move linearly between the driving device 100 and the sealing assembly 300 to drive the sealing member 320 to cooperate and seal with the workpiece 400. When a sealing test is required, the workpiece 400 can be placed on the positioning fixture. The first driving component 110 drives the first transmission component 200 to move to the sealing assembly 300. Then, the second driving component 120 drives the first transmission component 200 to connect with the sealing component 320. Under the drive of the first driving component 110, the first transmission component 200 can drive the sealing component 320 to slide to mate with the opening of the workpiece 400 that needs to be sealed, thereby achieving a seal. This eliminates the need for manual installation and is highly efficient. After the test is completed, the first driving component 110 can drive the sealing component 320 back to the base 310, and the second driving component 120 can drive the first transmission component 200 to disengage from the sealing component 320, preparing for the sealing of the next workpiece 400. No manual adjustment is required, resulting in high operating efficiency and low operating costs.

[0032] Specifically, the specific structure of the positioning fixture is not limited. After the workpiece 400 is placed and fixed in the positioning fixture, the valve port or cooling water port of the workpiece 400 is located between the drive device 100 and the sealing assembly 300. The specific connection method between the first drive component 110 and the second drive component 120 of the drive device 100 is not limited. Both are connected to the first transmission component 200. Before sealing, the first transmission component 200 is located on the side of the workpiece 400 closer to the drive device 100. After the workpiece 400 is fixed, the first drive component 110 can drive the first transmission component 200 through. The valve port moves to the seal 320. The second drive component 120 then drives the first transmission component 200 to connect with the seal 320. The specific connection method is not limited here. The first drive component 110 drives the first transmission component 200 to retract. At this time, the seal 320 slides relative to the base 310 until it abuts against the workpiece 400, thereby sealing the valve port inside the workpiece 400 to facilitate testing. After the test, the seal 320 can be reset to the base 310, and then the first transmission component 200 retracts to its initial state to prepare for the next workpiece 400 test. No manual installation of the seal 320 is required, resulting in high operating efficiency and reduced labor costs.

[0033] Reference Figure 3 and Figure 6 In some embodiments of this utility model, the sealing assembly 300 further includes an elastic element 330, which is connected to the sealing element 320 and the base 310. The elastic element 330 can drive the sealing element 320 to move toward the base 310. Specifically, the elastic element 330 can be configured as a spring, which can be configured as a tension spring. One end is connected to the sealing element 320, and the other end is connected to the base 310, so as to drive the sealing element 320 to reset toward the base 310. In actual operation, after the first transmission member 200 and the sealing element 320 are connected by transmission through the second driving member 120, the elastic element 330 deforms. After sealing is completed, the second driving member 120 can directly drive the first transmission member 200 to disengage from the sealing element 320, and the elastic element 330 can drive the sealing element 320 to automatically reset, which can further improve operating efficiency.

[0034] Reference Figures 1 to 5In some embodiments of this utility model, the first driving component 110 is a linear driving component, the second driving component 120 is located at the output end of the linear driving component, and the first transmission component 200 includes a pull rod 210 and a transmission part 220. The transmission part 220 is located on the pull rod 210, and the pull rod 210 is connected to the second driving component 120 in a transmission manner. The second driving component 120 can drive the transmission part 220 to be connected to the seal 320 in a transmission manner. Specifically, the linear driving component can be a cylinder, and the second driving component 120 can be directly located on the output rod of the cylinder. The cylinder can drive the second driving component 120 and the pull rod 210 to reciprocate linearly. The transmission part 220 can be located at the end of the pull rod 210. The specific structure of the transmission part 220 is not limited here. The second driving component 120 can drive the pull rod 210 to move and drive the transmission part 220 to be connected to the seal 320 in a transmission manner.

[0035] Understandably, the linear drive component can also be an electric telescopic pole.

[0036] Reference Figures 1 to 5 In some embodiments of this utility model, the second driving component 120 is configured as a rotary driving component, and the sealing component 320 is provided with a transmission hole 321. The rotary driving component can drive the first transmission component 200 to rotate to a first position and a second position. In the first position, the transmission part 220 can pass through the transmission hole 321. In the second position, the transmission part 220 can abut against the side of the sealing component 320 away from the driving device 100, so that the linear driving component can drive the pull rod 210 to pull the sealing component 320. Specifically, the rotary drive can be a rotary cylinder, which can drive the pull rod 210 to rotate to a predetermined angle. The transmission part 220 can be a non-circular structure. In the first position, the linear drive can drive the transmission part 220 through the transmission hole 321. After passing through, the rotary cylinder drives the transmission part 220 to rotate to the second position. At this time, the transmission part 220 cannot pass through the transmission hole 321 and can only abut against the side of the seal 320 away from the drive device 100 to form a transmission connection. When it is necessary to disengage, the rotary drive can simply drive the transmission part 220 to rotate back to the first position, and the seal 320 can be reset under the force of the elastic member 330, resulting in high operating efficiency.

[0037] Understandably, the rotary drive component can also be an electric motor.

[0038] Reference Figure 5 In some embodiments of this utility model, the transmission hole 321 is a waist-shaped hole, and the transmission part 220 is an elongated shape. Specifically, the elongated transmission part 220 can rotate 90° to a second position, so that both sides of the transmission part 220 can fully abut against the sealing member 320 for transmission.

[0039] It is understandable that the shapes of the transmission hole 321 and the transmission part 220 can also be square, triangular, or other shapes.

[0040] Reference Figure 5 In some embodiments of this utility model, a rounded corner is provided between the side wall and the end of the transmission part 220. Specifically, when the transmission part 220 needs to pass through the transmission hole 321, the rounded corner can play a guiding role so as to facilitate the alignment and cooperation between the transmission part 220 and the sealing member 320.

[0041] It is understandable that a chamfer may also be provided between the side wall and the end of the transmission part 220.

[0042] Reference Figure 5 In some embodiments of this utility model, the sealing element 320 includes a sealing plate 322 and a sealing ring. The sealing plate 322 has an annular groove 3221 on the side near the driving device 100, the sealing ring is disposed in the annular groove 3221, and the transmission hole 321 is disposed in the sealing plate 322. Specifically, the sealing plate 322 can be a metal part to give it a certain strength to meet the strength requirements of the transmission engagement with the first transmission element 200. The annular groove 3221 can be provided on the sealing plate 322 to place the sealing ring for sealing. The sealing ring has a simple structure, good sealing effect, and is also easy to disassemble and replace.

[0043] Reference Figures 3 to 6 In some embodiments of this utility model, the base 310 is provided with a sliding hole 311 and a positioning groove 312, and the sealing member 320 also includes a sliding rod 323 and a baffle 324. The sliding rod 323 is slidably engaged with the sliding hole 311. One end of the sliding rod 323 near the driving device 100 is connected to the sealing plate 322, and the other end is connected to the baffle 324. One end of the elastic member 330 abuts against the baffle 324, and the other end abuts against the positioning groove 312. Specifically, the sealing plate 322 can slide in a straight line through the sliding rod 323 in cooperation with the sliding hole 311. The sealing plate 322 and the baffle 324 are located on both sides of the base 310. The elastic element 330 can be set as a spring, with one end abutting against the side of the baffle 324 near the driving device 100, and the other end abutting against the positioning groove 312 on the side of the base 310 away from the driving device 100. When the sealing element 320 slides out, the baffle 324 can compress the elastic element 330 so that the elastic element 330 has an elastic force to drive the sealing plate 322 toward the base 310 to reset.

[0044] It is understandable that two slide rods 323 and two slide holes 311 can be provided, and baffles 324 are provided on the two slide rods 323 to improve sliding stability.

[0045] Reference Figure 5In some embodiments of this utility model, the base 310 is provided with a first adjustment hole 313, and the base 310 is connected to the positioning fixture by bolts through the first adjustment hole 313. Specifically, the first adjustment hole 313 can be designed as an oblong hole so that the position of the base 310 on the positioning fixture is adjustable.

[0046] Reference Figure 5 In some embodiments of this utility model, the first driving component 110 is provided with a connecting seat 111, the connecting seat 111 is provided with a second adjusting hole 1111, and the connecting seat 111 is connected to the positioning fixture by bolts through the second adjusting hole 1111. Specifically, the second adjusting hole 1111 can be set as an oblong hole so that the position of the connecting seat 111 on the positioning fixture is adjustable.

[0047] It is understood that the second drive component 120 can also be connected to the first drive component 110 via an adjustment seat, which can adjust the relative position of the second drive component 120 and the first drive component 110.
