Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology for all-in-one controllers, and specifically to a portable airtightness testing device for all-in-one controllers. Background Technology

[0002] With the rapid development of new energy vehicles, the requirements for the high integration of electric vehicles are constantly increasing. Previously, components such as the drive motor control unit, DC / DC converter, electric power steering control unit, air compressor control unit, and high-voltage power distribution unit were separate components, scattered throughout the vehicle, placing greater demands on overall vehicle space. This scattered arrangement of components requires multiple mounting brackets, wiring harnesses, and multiple housings, resulting in relatively high costs. Furthermore, the dispersed parts require isolated cooling structures for each component, further increasing costs and raising the control requirements for the entire vehicle.

[0003] Cost reduction and miniaturization of components are inevitable trends, and controllers for new energy vehicles are gradually developing towards high integration, evolving from single modules to three-in-one, and even six-in-one and seven-in-one. However, the integrated new energy controllers are used under high current and high power conditions, so enhanced heat dissipation is also necessary. Therefore, multi-in-one controllers are designed with cooling water channels that run through each module to ensure that heat is carried away to avoid overheating damage. For example, CN221948644U discloses a cooling water channel for a multi-in-one controller, where water enters from the inlet, passes through a heat dissipation cavity one, and then splits into two paths: one path flows out through a heat dissipation cavity two and exits from the outlet, while the other path flows out directly from the outlet through a splitting cut.

[0004] In development, testing, and market after-sales service, when a multi-function controller malfunctions and is identified as a faulty module, replacing the entire controller is not economical; replacing a single module controller is the best option. However, after replacing the module, ensuring the sealing of the cooling water channels is crucial. Currently, there is no helium leak testing equipment—the kind used for sealing tests at the factory for multi-function controllers—to perform airtightness testing on the multi-function controller after module replacement. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a portable airtightness testing device for all-in-one controllers. This device performs a sealing test on all-in-one controllers after module replacement, detecting potential failures such as missing or damaged sealing rings in the cooling water channels, or whether the sealing interface is compressed. This helps prevent all-in-one controllers after module replacement from becoming unusable due to water immersion caused by damage to the cooling water channels.

[0006] This utility model is achieved through the following technical solution:

[0007] A portable airtightness testing device for an all-in-one controller includes a handheld digital display air pump and a digital display pressure gauge. The all-in-one controller has a cooling water channel, an inlet, and an outlet. The inlet and outlet are connected to the cooling water channel. The handheld digital display air pump is connected to the inlet for inflating the cooling water channel inside the all-in-one controller. The digital display pressure gauge is connected to the outlet for monitoring the pressure of the cooling water channel.

[0008] In a further preferred embodiment, the equipment also includes pipe one and pipe two, with the handheld digital air pump connected to the water inlet via pipe one and the digital pressure gauge connected to the water outlet via pipe two.

[0009] A further preferred embodiment is provided with a conversion joint 1 at the connection between pipe 1 and the water inlet, and a conversion joint 2 at the connection between pipe 2 and the water outlet.

[0010] In a further preferred embodiment, an adapter module is provided at the connection between the handheld digital display air pump and pipe one and the connection between the digital display pressure gauge and pipe two. The adapter module is used to fix the handheld digital display air pump to pipe one and the digital display pressure gauge to pipe two.

[0011] The beneficial effects of this utility model are:

[0012] This utility model discloses a portable airtightness testing device for an all-in-one controller. A handheld digital display air pump inflates the cooling water channel cavity of the all-in-one controller, and a digital display pressure gauge monitors the pressure value and pressure changes within the cooling water channel cavity. This device performs a sealing test on the all-in-one controller after module replacement, ensuring the airtightness of the cooling water channel is intact. This prevents the all-in-one controller from becoming unusable due to water immersion after module replacement.

[0023] The handheld digital display air pump, also known as a digital air pump, vehicle air pump, or digital display air pump, is a device that uses atmospheric pressure to inflate tires, balls, rubber boats, air mattresses, and other equipment. It operates on 12V and has a working temperature range of -20℃ to 50℃, suitable for various applications including cars, motorcycles, and bicycles. The device features an LCD digital display and supports conversion between four units: PSI, BAR, KG / CM2, and KPA. It has a preset air pressure automatic shutdown function; inflation will not start if the preset value is lower than the actual air pressure. The setting can be adjusted in 0.05 bar increments using the ± keys. It supports dual power supply modes: 12V cigarette lighter socket and rechargeable battery, and comes with various sizes of inflator nozzles, air cables, and other accessories.

[0024] The Digital Pressure Gauge 2 is an intelligent pressure measuring instrument employing low-power technology and is ISO9001 quality system certified. The instrument operates within a temperature range of 0 to 50°C. Powered by a built-in AA lithium battery or rechargeable battery, it features a six-digit LCD display showing real-time pressure values ​​and supports switching between ten pressure units. The instrument boasts a compact design (φ100mm × 34mm), covering a pressure measurement range of -100kPa to 250MPa with a maximum accuracy of ±0.025%FS. An integrated high-precision sensor enables rapid pressure response and includes temperature and pressure compensation and self-diagnostic functions. A built-in serial interface allows for interfacing with automatic pressure calibration system software and supports data storage. This lightweight, low-cost airtightness testing device allows for convenient after-sales maintenance anytime, anywhere. The inflation pressure and interface size can be adjusted for various application conditions, offering high adaptability.

[0025] The working principle of this utility model is as follows: The handheld digital display air pump 1 is set to a specified pressure (i.e., a set pressure value), such as 2.5 bar or 3 bar, to match the actual application pressure of the cooling water channel 7 of the multi-function controller 4. The handheld digital display air pump 1 is started to inflate the cooling water channel 7 cavity of the multi-function controller 4. When the handheld digital display air pump 1 detects that the pressure inside the cooling water channel 7 cavity has reached the set pressure value, it will stop inflating. At this time, the digital display pressure gauge 2 will monitor the pressure change inside the cooling water channel 7 cavity in real time. When the value of the digital display pressure gauge 2 stabilizes near the set pressure value and remains unchanged for 60 seconds, there is no leakage in the cooling water channel 7 system of the multi-function controller 4; the airtightness of the multi-function controller 4 is intact. If the value of the digital display pressure gauge 2 changes rapidly, there is a leak in the cooling water channel 7 system of the multi-function controller 4, and the airtightness of the multi-function controller 4 is damaged.
