However, during the test, the tester did not operate in a standardized manner. The tester opened the protective cover door when the hub motor did not completely stop rotating, so there is still a mobile test safety hazard. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a hub motor protective double-station testing device which can forcibly lock the protective cover by an electric push rod when the hub motor is still rotating during testing to avoid opening the protective door due to misoperation or irregular operation.

The spherical protrusion is fixedly installed on the main frame of the equipment, the lower end of the connecting rod is fixedly installed on the supporting block, the floating block is slidably sleeved on the top of the connecting rod, and the spring is sleeved on the connecting rod. The upper and lower ends of the spring are respectively fixedly connected with the floating block and the supporting block. A touch rod matching the hemispherical protrusion is fixedly installed on the top of the floating block, and the top of the touch rod is set to a spherical structure. A touch switch is fixedly installed in the floating block, and the limit bolt limits the upward floating position of the floating block. The electric push rod is fixedly installed on the main frame of the equipment, and a slot matching the actuator rod of the electric push rod is set at the bottom of the protective cover. The electric push rod and the touch switch are respectively connected to the control module through circuits.

[0005] Preferably, the protective cover is provided with an observation window with a transparent plate structure.

[0006] Preferably, the longitudinal cross-section of the support surface of the synchronous test wheel is an arc-shaped concave structure.

[0007] Preferably, support and adjustment feet are screwed onto the bottom of the main frame of the equipment.

[0008] Compared with the prior art, the advantages of the utility model are as follows: the test equipment has two left and right test stations, and the test stations of the two test chambers can be protected or opened by moving the protective cover, which can improve the assembly and disassembly efficiency. In addition, the switch button of the touch switch contacts the connecting rod to generate an electrical signal that is transmitted to the control module, which can ensure that when the hub motor is still rotating, the control module controls the actuator rod of the electric push rod to be forced to extend into the slot of the protective cover to avoid the protective cover from moving left and right along the first linear slide rail and the second linear slide rail, thereby improving the safety during the test operation.

[0012] The utility model is described in detail below in conjunction with specific implementation methods:

[0013] like Figure 1 and Figure 2A hub motor protective double-station test device is shown, comprising a device main frame 1, a partition 12, a first linear slide 2, a second linear slide 21, a protective cover 3, a clamping mechanism 4, a limit bolt 43, an electric push rod 6, a bearing block 7, a floating block 71, a connecting rod and a spring 72, wherein the first linear slide 2 and the second linear slide 21 are horizontally fixedly installed on the top and front side of the device main frame 1, the protective cover 3 is slidably installed on the first linear slide 2 and the second linear slide 21, the partition 12 seals and separates the device main frame 1 into two left and right test chambers 11, the clamping mechanism 4 is fixedly installed in the test chamber 11, and a synchronous test wheel 5 is rotatably installed at the bottom of the clamping mechanism 4, and a hemispherical protrusion 42 is provided on the central axis 41 of the synchronous test wheel 5, and the bearing block 7 is fixedly mounted on the main frame 1 of the equipment, the lower end of the connecting rod is fixedly mounted on the bearing block 7, the floating block 71 is slidably sleeved on the top of the connecting rod, the spring 72 is sleeved on the connecting rod, the upper and lower ends of the spring 72 are respectively fixedly connected to the floating block 71 and the bearing block 7, the top of the floating block 71 is fixedly mounted with a touch rod 74 that matches the hemispherical protrusion 42, the top of the touch rod 74 is set to a spherical structure, a touch switch 75 is fixedly mounted in the floating block 71, the limit bolt 43 limits the upward floating position of the floating block 71, the electric push rod 6 is fixedly mounted on the main frame 1 of the equipment, the bottom of the protective cover 3 is provided with a slot that matches the actuator rod of the electric push rod 6, the electric push rod 6 and the touch switch 75 are respectively connected to the control module through circuits.

[0014] The protective cover 3 is provided with an observation window 31 of a transparent plate structure, so as to observe the test status of the hub motor 10 in the protective cover 3 .

[0015] The longitudinal cross-section of the support surface of the synchronous test wheel 5 is an arc-shaped concave structure, which increases the contact area between the test wheel 5 and the load wheel of the hub motor 10, avoids the problem of excessive wear due to excessive pressure caused by the small local contact area between the two, and can extend the service life of the synchronous test wheel 5.

[0016] A support adjustment foot 13 is screwed and installed at the bottom of the main frame 1 of the equipment. The support adjustment foot 13 is rotated to adjust its installation height to prevent the test equipment from shaking during the test operation.

When the hub motor 10 is started, the synchronous test wheel 5 is driven to rotate synchronously.

After the switch button of the touch switch 75 contacts the connecting rod, an electrical signal is generated. If the control module can receive the electrical signal of the touch switch 75 within 3 seconds, the actuator rod of the control electric push rod 6 is always extended and embedded in the slot of the protective cover 3 to prevent the protective cover 3 from being opened by misoperation or irregular operation.
