[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0032] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] A device for testing an electric vehicle handlebar can quickly and conveniently measure the dimensions of the handlebar, improve work efficiency, and test different models of handlebars with one device, achieving device normalization.

[0034] Specifically, as shown in Figure 1 The device includes a small module 1, a base 2, a bracket 3, and a vertical pipe testing mechanism 4. The small module 1 and the bracket 3 are fixed to the upper end surface of the base 2, and the vertical pipe testing mechanism 4 is vertically slidingly connected to the bracket 3. The handlebar is placed above the small module 1 to check the hole distance standard of the small parts of the handlebar. The vertical pipe testing mechanism 4 wraps around the handlebar pipe, and the vertical pipe testing mechanism 4 can slide on the bracket 3 through a sliding rail to test the diameter and outer diameter of the handlebar pipe pin shaft hole 5.

[0035] Specifically, as shown in Figure 2As shown, the small module 1 includes a protrusion 8, a pin column 9, a dovetail groove 10, and the small module 1 is slidably connected with the base 2 through the dovetail groove 10 guide rail. The protrusion 8 is located at the upper end of the small module 1, and the upper side of the protrusion 8 is arc-shaped, which is used to detect the arc radius of the handle small piece by fitting with the handle small piece. A plurality of pin columns 9 are vertically fixed on the upper end of the small module 1 and symmetrically distributed around the protrusion 8. The pin column 9 cooperates with each hole of the handle small piece to inspect the diameter of the threaded hole and the hole spacing. During the inspection, the handle is inverted and placed on the small module 1. If the shaft column cannot be completely inserted into the small hole and the small module 1 cannot be completely fitted, it is considered that the hole position of the handle small piece does not meet the standard. On the contrary, if the shaft column can be completely inserted into the small hole and the small module 1 is completely fitted, it is considered that the handle small piece meets the standard.

[0036] Specifically as Figure 3 As shown, the outer diameter inspection module 6 is provided with a pin shaft hole 5 and a bottom baffle slot 7, and the pin shaft and the bottom baffle are inserted into the outer diameter inspection module 6 through the pin shaft hole 5 and the bottom baffle slot 7. The pin shaft is used to detect the hole diameter of the handle stand pipe pin shaft. The bottom baffle cooperates with the pin shaft to verify the center distance of the handle pin shaft hole 5 and the bottom end distance of the handle. When the outer diameter inspection module 6 wraps the outer diameter of the handle, when the pin shaft passes through the outer diameter inspection module 6 and the handle, the handle stand pipe pin shaft hole 5 diameter is qualified. When the pin shaft and the bottom baffle both pass through the outer diameter inspection module 6 and the handle, the center distance of the handle pin shaft hole 5 and the bottom end distance of the handle are qualified. The pin shaft hole 5 is a circular through hole, and the pin shaft and the pin shaft hole 5 are detachably cooperated. The bottom baffle slot 7 is a rectangular through slot, and the bottom baffle slot 7 is located above the pin shaft hole 5. The bottom baffle and the bottom baffle slot 7 are detachably cooperated. The front end of the outer diameter inspection module 6 is recessed to surround and clamp the handle stand pipe to detect the outer diameter thereof.

[0037] Further, during the inspection, the stand pipe inspection mechanism 4 is slid upward to the highest point, and a space for placing the handle is reserved below. The stand pipe inspection mechanism 4 is slid downward to the position where the pin shaft hole 5 and the handle pin shaft hole 5 are on the same center line. The pin shaft is inserted into the handle inspection mechanism. If it can completely pass through the mechanism, the inner diameter of the handle pin shaft hole 5 meets the standard. Otherwise, it is considered that the handle pin shaft hole 5 is too small and does not meet the standard. The bottom baffle is inserted into the handle inspection mechanism, and it is observed whether the bottom baffle interferes with the handle. If they interfere with each other, it is considered that the size of the handle pin shaft hole 5 from the bottom end of the handle does not meet the standard. Otherwise, it is considered that it meets the standard.

[0038] Specifically as Figure 4 As shown, the outer diameter inspection module 6 can be replaced by a ring mechanism, which can be fully surrounded for detection and has the same effect.

[0039] Specifically, the bracket 3 is in the shape of "L", and the bottom end thereof is fixed on the base 2 by bolts.

[0040] Specifically, the spatial connecting line of the action position of the riser inspection mechanism 4 and the action position of the small module 1 is parallel to the column, and the riser inspection mechanism 4 and the small module 1 are parallel to the column during detection.
