Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a comprehensive load testing device for an automobile electronic water pump. Background Art

[0002] Electronic water pumps provide power circulation for the cooling systems of many new energy vehicles, conventional fuel vehicles and other vehicles. To ensure that the electronic water pumps can operate stably in the vehicle cooling system, it is necessary to use testing equipment to test their functions and performance after assembly.

[0003] Current electronic water pump testing devices are unable to detect whether the electronic water pump can operate normally when mud and sand are mixed inside. Therefore, some people have thought of setting up a mud and water tank to provide mud and water for the electronic water pump. For example, Chinese utility model patent No. CN216207018U specifically discloses a testing device for a low-power electronic water pump.

[0004] However, during actual use of the electronic water pump testing device, people will find that the device does not have a structure for limiting the electronic water pump, which results in poor stability of the electronic water pump during actual operation, affecting the normal detection of the electronic water pump.

[0022] See also Figure 1-4The present invention provides a technical solution: a comprehensive load test device for an automotive electronic water pump, comprising an upper housing 1, a lower housing 2 disposed below the upper housing 1, a water inlet 101 and a drain outlet 102 disposed on either side of the upper housing 1, a protective door 103 disposed on the front of the upper housing 1, a mounting plate 104 disposed within the upper housing 1, a workbench 3 disposed above the mounting plate 104, a chute 301 disposed above the workbench 3, a bidirectional screw 4 disposed within the chute 301, one end of the bidirectional screw 4 being rotatably connected to the chute 301, the other end of the bidirectional screw 4 passing through the workbench 3 and connected to a knob 403, two screw sliders 401 symmetrically threadedly connected to the bidirectional screw 4, each screw slider 401 being provided with a clamping plate 402, and a plurality of shock absorbers 5 disposed between the workbench 3 and the mounting plate 104. The shock absorbers 5 are composed of springs and dampers. By placing the automobile electronic water pump on the workbench 3 and rotating the bidirectional screw 4, the bidirectional screw 4 drives the screw slider 401 to move, so that the screw slider 401 drives the clamping plate 402 to clamp the automobile electronic water pump, thereby fixing the electronic water pump. The water inlet 101 and the drain outlet 102 are respectively used to connect the input and output ends of the electronic water pump, and the shock absorber 5 plays a buffering and vibration reduction effect.

[0023] A water injection pipe 1011 is provided on the water injection port 101, and a first water outlet pipe 1021 and a second water outlet pipe 1022 are provided on the water discharge port 102. The water injection pipe 1011 and the first water outlet pipe 1021 are both located on the inner side of the upper box body 1, and the second water outlet pipe 1022 is located on the outer side of the upper box body 1, and the second water outlet pipe 1022 is connected to the lower box body 2. The water injection pipe 1011 and the first water outlet pipe 1021 are respectively connected to the input end and output end of the electronic water pump, and the second water outlet pipe 1022 is used to discharge the water discharged by the electronic water pump into the lower box body 2 for storage.

[0024] An observation window 1030 is provided on the protective door 103, and the observation window 1030 is provided mainly for the convenience of the staff to check the internal situation.

[0025] A drain outlet 201 is provided on the side of the lower box body 2 , and a valve is provided on the drain outlet 201 . The drain outlet 201 is used to discharge water in the lower box body 2 .

[0027] A fixing plate 4021 is provided below the clamping plate 402 , and the fixing plate 4021 is connected to the screw slider 401 via bolts, thereby achieving detachable installation.

[0028] In summary, when using this device, it is only necessary to place the electronic water pump on the workbench 3, and then turn the knob 403 so that the knob 403 drives the bidirectional screw 4 to rotate, so that the bidirectional screw 4 drives the two screw sliders 401 to approach each other, so that the screw sliders 401 drive the clamping plate 402 to clamp the electronic water pump. After clamping, the water injection pipe 1011 is connected to the input end of the electronic water pump, and the first water outlet pipe 1021 is connected to the output end of the electronic water pump. Then, water can be injected into the electronic water pump for testing. During the testing process, the shock absorber 5 can play a buffering and vibration reduction effect, thereby improving the overall stability. After the test is completed, the bidirectional screw 4 is rotated in the opposite direction so that the screw sliders 401 move away from each other, and at the same time, the clamping plate 402 is driven away from the electronic water pump to cancel the fixation, and then it can be removed.

[0029] It is worth noting that the entire device is controlled by a master control button. Since the devices matched with the control button are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
