Description

Technical Field

[0001] This utility model relates to the field of new energy battery box technology, specifically to a battery box airtightness testing platform. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage systems, the battery housing, as a crucial load-bearing and protective component of the battery module, is of paramount importance in terms of safety and reliability. During operation, the battery housing needs to possess excellent sealing performance to prevent the intrusion of external contaminants such as moisture and dust, while also preventing the leakage of harmful gases generated inside the battery, thereby ensuring the stable operation of the battery system and the safety of personnel. Therefore, the battery housing cover must undergo airtightness testing before being put into use.

[0003] In the existing technology, the battery box is placed on an airtightness testing platform for airtightness testing. When the battery box is placed on the airtightness testing platform, its bottom can fit tightly against the surface of the airtightness testing platform. When the airtightness test is over, there is a situation where it is difficult to remove the battery box from the airtightness testing platform. Utility Model Content

[0004] In view of this, the present invention provides a battery box airtightness testing platform, which makes it easy for operators to remove the battery box from the surface of the testing platform.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A battery box airtightness testing platform includes a mounting base, an airtightness testing platform fixed on the top of the mounting base, a battery box to be tested placed on the top of the airtightness testing platform, and pressing components distributed circumferentially on the airtightness testing platform. The pressing components are used to press the battery box to be tested tightly against the top of the airtightness testing platform. The platform is characterized in that: a positioning and lifting component is provided circumferentially on the top of the airtightness testing platform. The positioning and lifting component includes a support block, a positioning pin vertically disposed on the upper end of the support block, and a lifting component disposed on the lower end of the support block. The positioning pin is used to position the battery box in a positioning hole circumferentially. The lifting component can drive the support block to move upward, so that the support block can lift the battery box upward.

[0007] With the above structure, the positioning pin can facilitate the quick positioning of the battery box. After the air tightness test is completed, the lifting component and the support block can be used to easily remove the battery box from the air tightness test platform. The combination of the positioning pin and the support block also makes the overall installation structure more compact.

[0008] Preferably, the airtightness testing platform is equipped with a limit sensor at its top. The limit sensor is electrically connected to the pressing assembly and has a horizontally arranged limiting rod for contacting the battery box to be tested. With this structure, the limit sensor can detect whether the battery box is properly installed, while preventing employee injury due to misoperation.

[0009] Preferably, the airtightness testing platform is fixedly mounted on top of the mounting base by support columns, and balancing bubble devices are provided around the top of the airtightness testing platform. With this structure, the airtightness testing platform can be checked for levelness using the balancing bubble devices, and stable installation can be ensured by adjusting the support columns.

[0010] Preferably, an adhesive strip is provided between the airtightness testing platform and the battery box to be tested, and a limiting block is provided on the top of the airtightness testing platform near the adhesive strip, the height of the limiting block being smaller than the height of the adhesive strip. With this structure, when the pressing component presses against the battery box, the limiting block can limit the pressing stroke of the battery box, preventing the adhesive strip from being damaged.

[0011] Preferably, the airtightness testing platform has a drainage trough at its top, with a vertically penetrating drainage hole in the trough, and a vertically upward-extending water-blocking block at the top edge of the platform. This structure facilitates the drainage of residual liquid.

[0012] Preferably, the pressing assembly is a telescopic cylinder, and each telescopic cylinder is connected to a pressure relief valve. This structure prevents excessive pressure from the pressing assembly from deforming the battery casing.

[0013] Preferably, a drying filter is provided at the end of the pressure relief valve away from the pressing assembly. This structure prevents moisture from entering the airtight instrument, thus ensuring its service life.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The battery box airtightness testing platform provided by this utility model uses positioning pins to facilitate quick positioning of the battery box. After the airtightness test is completed, the lifting component and support block work together to facilitate the removal of the battery box from the airtightness testing platform. The combination of positioning pins and support blocks also makes the overall installation structure more compact. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a battery box airtightness testing platform includes a mounting base 1, an airtightness testing platform 2 fixedly mounted on the top of the mounting base 1, a battery box 14 to be tested placed on the top of the airtightness testing platform 2, pressing components 16 distributed circumferentially on the airtightness testing platform 2, the pressing components 16 are used to press the battery box 14 to be tested against the top of the airtightness testing platform 2, a positioning and lifting component is fixedly mounted circumferentially on the top of the airtightness testing platform 2, the positioning and lifting component includes a positioning pin 3 and a lifting component 15 for driving the positioning pin 3 to move vertically, a support block 4 is connected between the positioning pin 3 and the lifting component 15, when the driving component 15 moves and drives the positioning pin 3 to move upward, the support block 4 can finally support the bottom of the battery box 14 and can lift the battery box 14.

[0024] The battery box 14 has a mounting sleeve 14a around its circumference. The mounting sleeve 14a has a central positioning hole. After the battery box 14 is placed on the airtightness testing platform 2, the central positioning hole of the mounting sleeve 14a is fitted onto the positioning pin 3, which makes it easier for the battery box 14 to be positioned and installed on the airtightness testing platform 2 more quickly. After the airtightness test of the battery box 14 is completed, the lifting component 15 drives the support block 4 and the positioning pin 3 to move upward as a whole. The support block 4 can abut against the bottom of the battery box 14 and finally force the battery box 14 to be lifted upward, which makes it easier for the battery box 14 to be taken out from the top of the airtightness testing platform 2. The combination of the two also makes the overall structure more compact.

[0025] In this embodiment, the lifting component 15 is a lifting cylinder. A through hole 2b is opened on the top of the airtightness testing platform 2 in a vertical direction. The support block 4 is inserted into the through hole 2b and can move up and down within the through hole 2b.

[0026] like Figure 3 As shown, a limit sensor 5 is installed on the top of the airtightness testing platform 2. The limit sensor 5 has a horizontally arranged limiting rod 5a, which is used to contact the battery box 14 to be tested to detect whether the battery box 14 is installed in place. In this embodiment, the limit sensor 5 is electrically connected to the pressing assembly 16. When the limit sensor 5 detects that the battery box 14 is not installed in place, the pressing assembly 16 cannot operate, thereby improving the safety of the equipment and preventing employees from being injured due to misoperation.

[0027] like Figure 1 and Figure 4 As shown, the airtightness testing platform 2 is fixedly installed on the top of the mounting base 1 by support columns 7. Balance bubble devices 6 are installed around the top of the airtightness testing platform 2. These devices ensure that the airtightness testing platform 2 is level, thereby guaranteeing the airtightness testing effect of the entire platform. When the airtightness testing platform 2 is not level, the height of the support columns 7 can be adjusted to ensure it is level. Since the balance bubble device 6 is existing technology, it will not be described in detail in this embodiment.

[0028] like Figure 4 As shown, in order to ensure that the battery box 14 is tightly pressed against the top surface of the airtightness testing platform 2, a rubber strip 8 is usually provided between the battery box 14 and the airtightness testing platform 2. In this embodiment, in order to ensure that the pressing component 16 will not damage the rubber strip 8 during the pressing process, a limiting block 9 is fixedly installed on the top of the airtightness testing platform 2 near the rubber strip 8, and the height of the limiting block 9 is smaller than the height of the rubber strip 8. When the battery box 14 is pressed down, it can first contact the rubber strip 8 and finally abut against the top of the limiting block 9, thereby preventing the rubber strip 8 from being deformed by pressure and damaged.

[0029] like Figure 1 and Figure 5 As shown, a drainage groove 10 is formed on the top of the airtightness testing platform 2, and a vertically penetrating drainage hole 11 is provided on the drainage groove 10. In this embodiment, the battery box 14 can be tested in advance by immersion in water to see if it is pressed tightly against the surface of the airtightness testing platform 2. Specifically, water is injected into the surface of the airtightness testing platform 2, and it is observed whether there are air bubbles at the contact position between the battery box 14 and the airtightness testing platform 2. After the test is completed, the drainage hole 11 can drain the water to avoid residual water from affecting the service life of the airtightness testing platform 2. A vertically extending water-blocking block 2a is also formed on the top edge of the airtightness testing platform 2 to prevent sewage from flowing everywhere.

[0030] In this embodiment, the pressing component 16 is a telescopic cylinder. In order to prevent the battery box 14 from deforming due to excessive pressure of the pressing component 16, each pressing component 16 is connected to a pressure relief valve 12 through an air passage at its far end.

[0031] Meanwhile, in order to ensure that the gas is dry and does not affect the service life of the pressing assembly 16, a drying filter 13 is also connected between the end of the pressure relief valve 12 away from the pressing assembly 16 and the gas source.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
