Description

Technical Field

[0001] The present application relates to the technical field of battery box air tightness detection, and in particular to a water immersion detection tool for energy storage battery boxes. Background Art

[0002] The sealing of the battery box is a key measure to ensure the safety and reliability of electric vehicle power batteries. In new energy vehicles, power batteries are the power source, and their performance and safety are directly related to the safety of the entire vehicle.

[0003] In the related art, the energy storage battery box water immersion detection tool is to seal all the openings of the energy storage battery box, then immerse the sealed energy storage battery box in water, and finally apply air pressure to the sealed energy storage battery box. Under the pressure maintaining state, observe whether there is any leakage point in the box immersed in water. At present, before the energy storage battery box enters the water, it is necessary to position the box on the tooling, and then seal the open mouth at the bottom of the box and the holes on the side. The positioning method is: apply thrust to the side of the box to make the box press against the positioning block; the sealing method is: apply pressure to the top of the box to make the bottom of the box press on the sealing ring to achieve sealing, and the side holes are sealed by applying pressure to the sealing structure so that the sealing structure presses on the holes on the side of the box. However, this positioning and sealing method requires multi-directional and multi-point force application. First, if a separate cylinder drive is used, the air path mechanism is complicated, so how to simplify the drive structure becomes a technical problem that needs to be solved. Second, under normal circumstances, if the cylinder is immersed in water with the box, the requirements for the cylinder will increase accordingly, and a waterproof cylinder needs to be used. If the cylinder is not immersed in water, its transmission structure will also increase accordingly. Therefore, under the premise of taking into account the simplification of the drive, considering that the drive element is not immersed in water also becomes a technical problem that needs to be solved.

The torsion spring 4123 is sleeved on the pin shaft. The two ends of the torsion spring 4123 are respectively connected to the ear plate 4122 and the first hinge seat 411. The elastic force of the torsion spring 4123 pushes the swing frame 4121 to swing backward. The slide 4125 is fixedly connected to the front end of the swing frame 4121. The rear end of the pressing frame 4124 is slidably connected to the slide 4125. The front end of the clamping frame 4124 is pressed against the top of the energy storage battery box, the second guide ring 413 is fixedly connected to the rear end of the swing frame 4121, and the steel cable tensioning force application mechanism 500 can pull the second guide ring 413 upwards.

The lower layer of the steel cable 570 is redirected by the second fixed pulley 560 and passes through the front and rear ends of the lower side of the base frame 530. When the steel cable 570 passes through the front and rear ends of the base frame 530, the steel cable 570 passes through the guide portion 443. The steel cable 570 is first stopped by the guide portion 443, so that the steel cable 570 first applies pressure to the first guide ring 370, the fourth guide ring 2222 of the side push rod portion 222, and the fourth guide ring 2222 of the end push rod portion 242. When the applied pressure is greater than the resistance of the guide portion 443 to the steel cable 570, the blocked portion of the steel cable 570 (the step buffer block 570) is 2) After passing the guide portion 443, the steel cable member 570 passes through the front end of the base frame 530 and then passes through the upper ends of four double-layer guide frames 510 and four upper-layer guide frames 520 to form an upper-layer arrangement of the steel cable member 570.

[0039] See also Figures 1 to 13The base frame 530 includes a base plate 531 and a fixed guide ring 532.

One end of the bumper 4435 extends into the insertion hole 4432. The step buffer block 572 can push the end of the bumper 4435 to retract, and the step buffer block 572 can pass over the bumper 4435. The step buffer block 572 is first stopped by the bumping bead 4435 on the guide block 4431. When the force applied to the steel cable 571 is greater than the resistance of the bumping bead 4435 to the step buffer block 572, the step buffer block 572 compresses the bumping bead 4435, so that the step buffer block 572 passes through the through hole 4432 on the guide block 4431. The step buffer block 572 is guided by the guide groove 4433 before and after entering the through hole 4432, so that the step buffer block 572 can pass through the through hole 4432 easily. When the winch 540 is driven to tighten the steel cable 571, the step buffer block 572 passes through the insertion hole 4432 to reach the rear end of the guide block 4431. When the winch 540 is driven to release the steel cable 571, the steel cable 571 pulls the steel cable 571 under the elastic force of the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442, and the steel cable 571 drives the step buffer block 572 to pass back through the insertion hole 4432, so that the step buffer block 572 reaches the front end of the guide block 4431. When the steel cable member 570 passes through the front and rear ends of the base frame 530, the steel cable 571 successively hits the fixed guide ring 532 at the rear end and the front end of the base plate 531.

When the upper layer of the steel cable member 570 is arranged, the steel cable 571 passes over the first top guide ring 513 of the double-layer guide rod 511 and the second top guide ring 522 of the upper layer guide rod 521, so that the steel cable 571 arranged at the upper layer is redirected by the first top guide ring 513 of the four double-layer guide rods 511 and the second top guide ring 522 of the upper layer guide rod 521.

[0041] Specifically, the working principle of the energy storage battery box water immersion detection tool is as follows: when in use, the driving winch 540 is started, and the driving winch 540 tightens the steel cable 571. The steel cable 571 is first redirected by the first fixed pulley 550, and then the steel cable 571 passes around the guide wheel 512 at the lower end of the four double-layer guide rods 511, and the rope lock frame 514 blocks the steel cable 571 on the guide wheel 512, so that the guide wheel 512 at the lower end of the four double-layer guide rods 511 redirects to form the steel cable 571 arranged on the lower layer, and the steel cable 571 arranged on the lower layer passes through the first guide ring 370. , the fourth guide ring 2222 of the side pushing rod 222 and the fourth guide ring 2222 of the end pushing rod 242, thereby applying pressure to the first guide ring 370, the fourth guide ring 2222 of the side pushing rod 222 and the fourth guide ring 2222 of the end pushing rod 242, the fourth guide ring 2222 applies pressure to the second force plate 2221, the second force plate 2221 drives the second sliding bar 2223 to slide along the first mounting seat 221, the second force plate 2221 drives the second spring 2225 to shorten, and the elastic force of the second spring 2225 increases. In addition, the second sliding rod 2223 drives the first push plate 2224, and the first push plate 2224 drives the energy storage battery box to be pressed against the side positioning block 210. The principle that the end pushing rod 242 pushes the energy storage battery box to be pressed against the end positioning block 230 is the same as the principle that the side pushing rod 222 drives the energy storage battery box to be pressed against the side positioning block 210, so as to realize the positioning of the energy storage battery box. When the end pushing rod 242 and the side pushing rod 222 are positioning the energy storage battery box, the step buffer block 572 is firstly guided by the guide block 4431. The step buffer block 572 and the guide block 4431 are used as temporary support points to first position the energy storage battery box. When the force applied to the steel cable 571 is greater than the resistance of the step buffer block 572 exerted by the step buffer block 572 by the step buffer block 572, the step buffer block 572 compresses the step buffer block 4435, so that the step buffer block 572 passes through the insertion hole 4432 on the guide block 4431. The step buffer block 572 passes through the insertion hole 4432 and reaches the rear end of the guide block 4431, and the support effect of the guide block 4431 on the step buffer block 572 is released.After the lower arrangement of the steel cable 571 is redirected by the second fixed pulley 560, the steel cable 571 passes through the fixed guide rings 532 at the rear end and the front end of the base plate 531 in turn. When the steel cable 571 passes through the fixed guide rings 532 at the rear end and the front end of the base plate 531, the steel cable 571 passes through the insertion hole 4432 of the guide block 4431, and the steel cable 571 bypasses the first top guide ring 513 of the double-layer guide rod 511 and the second top guide ring 522 of the upper-layer guide rod 521. In this way, the upper arrangement is redirected by the first top guide ring 513 of the four double-layer guide rods 511 and the second top guide ring 522 of the upper-layer guide rod 521. The steel cable 571 passes through the second guide ring 413, the third guide ring 423 of the left top pressing member 420 and the third guide ring 423 of the rear end top pressing member 430. After the stepped buffer block 572 on the steel cable 571 passes through the insertion hole 4432 and reaches the rear end of the guide block 4431, the steel cable 571 applies an upward pulling force to the second guide ring 413, the third guide ring 423 of the left top pressing member 420 and the third guide ring 423 of the rear end top pressing member 430, and the second guide ring 413 pulls the rear end of the swing frame 4121 upward, and the ear plate 4122 of the swing frame 4121 passes through the pin shaft. The swing frame 4121 swings around the first hinge seat 411, the elastic force of the torsion spring 4123 increases, the swing frame 4121 drives the slide 4125 to swing downward, the pressing frame 4124 extends along the slide 4125 under the action of gravity, the pressing frame 4124 extends above the top of the energy storage battery case, and then the pressing frame 4124 presses the top of the energy storage battery case. When the tension of the steel cable tensioning force applying mechanism 500 on the second guide ring 413 is released, the swing frame 4121 swings upward at the front end under the elastic force of the torsion spring 4123, and the pressing frame 4124 leaves the top of the energy storage battery case first. The angle of the front end of the movable frame 4121 swings to the upper side, and the clamping frame 4124 is retracted along the slide 4125 under the action of gravity, so that the clamping frame 4124 leaves the top of the energy storage battery case, thereby reducing the situation where the clamping frame 4124 blocks the energy storage battery case when the energy storage battery case is replaced. The principle of the second return swing frame 422 and the third return swing frame 442 pressing the top of the energy storage battery case is the same as the principle of the first return swing frame 412 pressing the top of the energy storage battery case, thereby achieving compression around the top of the energy storage battery case, and then achieving sealing of the lower end opening of the energy storage battery case.In the above process, the first guide ring 370 applies pressure to the first force plate 320, and the first force plate 320 drives the first slide bar 340 to slide along the third mounting seat 310. The first force plate 320 drives the first spring 360 to shorten, and the elastic force of the first spring 360 increases. The first slide bar 340 drives the double-layer elastic sealing plug 330, and the double-layer elastic sealing plug 330 gradually presses on the energy storage battery box and presses on the side hole of the energy storage battery box to seal. The sealing plate 333 first seals the side hole of the energy storage battery box. Thereafter, the mounting plate 331 drives the buffer spring 332 to be compressed, and the elastic force of the buffer spring 332 increases. The sealing plate 333 is pressed against the side hole of the energy storage battery box. The pressure on the side hole of the energy storage battery case increases, and the position of the positioning nut 350 is adjusted to achieve the degree of compression of the buffer spring 332, thereby adjusting the pressure of the sealing plate 333 on the side hole of the energy storage battery case to seal the side hole of the energy storage battery case until the positioning nut 350 is against the third mounting seat 310. The pressure of the double-layer elastic sealing plugging member 330 on the energy storage battery case is adjusted by the positioning nut 350, so that the pressure of the double-layer elastic sealing plugging member 330 on the energy storage battery case is less than the pressure of the end pushing rod 242 on the energy storage battery case, so that the end pushing rod 242 can push the energy storage battery case toward the end positioning block 230. The energy storage battery box water immersion detection tool adopts the drive of a single drive winch 540 to perform multi-directional and multi-point force sealing of the energy storage battery box, and adopts a mechanical mechanism to simplify the circuit or gas path, which is convenient for inspection and maintenance. Under the premise of taking into account the simplification of the drive, the drive winch 540 is raised by the double-layer guide frame 510 and the upper guide frame 520, so that the drive element does not enter the water, thereby reducing the selection requirements for the drive element. After the energy storage battery box rises with the lifting platform 140 and protrudes out of the water, the winch 540 is driven to release the steel cable 571, and the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442 automatically return to their original positions under the elastic force, releasing the pressure on the top of the energy storage battery box, and the side pushing rod 222, the end pushing rod 242 and the double-layer elastic sealing plugging component 330 return to their original positions under the elastic force. At the same time, the steel cable 571 is pulled by the elastic force of the first return swing frame 412, the second return swing frame 422 and the third return swing frame 442, and the steel cable 571 drives the step buffer block 572 to pass back through the insertion hole 4432, so that the step buffer block 572 reaches the front end of the guide block 4431.
