Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a wiper motor's connecting axle mounting structure.
In this embodiment, referring to fig. 1-5, this connecting axle mounting structure of wiper motor, including motor 1 and reduction gear 2, still include connecting axle 20 and locking plate 21, be equipped with the shaft hole 22 that is used for installing the connecting axle on the shell of reduction gear, be equipped with spread groove 23 on the shaft hole inner wall, the spread groove opening part is equipped with blocks step 24, block and form step passageway 25 between step and the spread groove lateral wall, be equipped with on the outer wall of connecting axle and hang and lean on step 26, the locking plate top is equipped with inserted sheet 27 that is used for inserting the step passageway.
Among the above-mentioned technical scheme, with adopting removable lock pin structure between connecting axle and the shaft hole, not only connect stably, need not to process the screw thread moreover, reduction in production cost improves the performance of enterprises, has simple structure, convenient and practical connects stable advantage.
The realization principle is as follows: when the connecting shaft is assembled, the connecting shaft is hung on the step aligning step passageway and inserted into the shaft hole, then the connecting shaft is rotated, the hanging step is rotated to one side of the blocking step, then, one end of the inserting piece of the locking plate is aligned with the step passageway and inserted into the connecting groove, and the connecting shaft is locked. At the moment, the connecting shaft is fixed in the shaft hole and cannot rotate and be pulled out under the mutual restriction of the hanging step, the blocking step and the locking plate. When the lock is required to be disassembled, the lock plate is only required to be pulled out, and then the connecting shaft is rotated. Adopt this kind of removable lock pin structure, can be with the stable connection of connecting axle in the axle hole, need not processing screw thread, reduction in production cost connects stably moreover, the dismantlement in the later stage of also being convenient for.
Specifically, the two connecting grooves are arranged on the inner wall of the connecting groove in a facing manner; the thickness of the insert is 0.1-0.5mm less than the thickness of the body portion 28 of the locking tab; a first pouring inclined plane 29 is arranged at the top of the inserting piece; the connecting shaft comprises a connecting section 30, a left limiting step 31, a right limiting step 32 and a threaded column 33 which are integrally formed, and a positioning step 34 is arranged on the connecting section; a second pouring inclined plane 35 is arranged on the hanging step; the left limit step and the right limit step are provided with spacing steps 36 at equal intervals.
Among the above-mentioned technical scheme, the inclined plane is poured into to the first inclined plane and the second plays the guide effect of pouring into, makes things convenient for the inserted sheet and the insertion of being affiliated to the step, improves male smoothness nature. In addition, the positioning step plays a role in positioning the inserting piece.
The skilled person should understand that: although the present invention has been described in accordance with the above embodiments, the inventive concept is not limited to this embodiment, and any modification of the inventive concept will be included in the scope of the patent claims.
