Detailed Description
The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As shown in fig. 1 to 8, a gear shifting structure of a power tool according to an embodiment of the present utility model includes a push button assembly 1, a gear assembly 2, a connecting member 3, and an elastic member 4. The push button assembly 1 comprises a sliding plate 11 capable of moving linearly, and a jack 12 is arranged on the bottom wall of the sliding plate 11. The gear assembly 2 comprises a gear plate 21, a clamping block 23, an annular clamping groove 22 and a linear clamping groove 24, wherein the gear plate 21 is arranged below the sliding plate 11, the clamping block 23 is arranged on the gear plate 21, the annular clamping groove 22 is arranged around the clamping block 23, and the linear clamping groove 24 is communicated with the annular clamping groove 22. The connecting member 3 includes a first bending section 31, a middle section 32 and a second bending section 33, the first bending section 31 and the second bending section 33 are respectively disposed at two ends of the middle section 32, the first bending section 31 is bent downward and extends into the annular clamping groove 22 or the linear clamping groove 24, the second bending section 33 is bent upward and inserted into the insertion hole 12, and the second bending section 33 can rotate in the insertion hole 12. The two ends of the elastic piece 4 are respectively connected with the sliding plate 11 and the gear plate 21 and are used for driving the sliding plate 11 to reset. The clamping block 23 is provided with a clamping groove 231 at a position far away from the straight clamping groove 24, the clamping groove 231 can be clamped with the first bending section 31 of the connecting piece 3, a first clamping tip 232 is arranged at a position, close to the straight clamping groove 24, of the clamping block 23, the first clamping tip 232 is staggered with the axis of the straight clamping groove 24, an inward-protruding second clamping tip 25 is arranged on the outer ring of the annular clamping groove 22, the second clamping tip 25 is arranged on one side close to the clamping groove 231, and the vertex of the second clamping tip 25 is staggered with the vertex of the clamping groove 231.
As shown in fig. 7 and 8, in this embodiment, a first gear and a second gear may be provided, and when the sliding plate 11 of the push-button assembly 1 is pushed to the first gear, the first bending section 31 of the connecting member 3 is located in the positioning groove 231 on the positioning block 23, so as to fix the position of the sliding plate 11, and the elastic member 4 is in a compressed state. When the sliding plate 11 of the push-button assembly 1 is pushed to the second gear, the first bending section 31 of the connecting piece 3 is located in the straight line clamping groove 24 to fix the position of the sliding plate 11, the elastic piece 4 is restored to the normal state, and the elastic piece 4 can be an elastic member such as a spring or elastic rubber.
Referring to fig. 7, when the first gear is required to be shifted to the second gear, the sliding plate 11 is pushed to move the first curved section 31 from the locking groove 231 into the linear locking groove 24. The slide plate 11 is first pushed so that the first curved section 31 of the connector 3 is away from the detent groove 231. After the first bending section 31 contacts the second clamping tip 25 on the annular clamping groove 22, since the second clamping tip 25 and the clamping groove 231 are staggered, the contact part of the second clamping tip 25 and the first bending section 31 is not the central axis part of the contact part, but the side curved surface of the second clamping tip 25, so when the sliding plate 11 drives the first bending section 31 to move continuously, the first bending section 31 moves along the side of the second clamping tip 25, and in the process, the second bending section 33 rotates along the same step, so that the first bending section 31 can move smoothly along the side of the second clamping tip 25. When the first bending section 31 is far away from the clamping groove 231, the sliding plate 11 is released, the elastic member 4 rebounds to drive the sliding plate 11 to move reversely, and in this process, the sliding plate 11 drives the first bending section 31 to move into the linear clamping groove 24 along the annular clamping groove 22, so as to switch the gear to the second gear.
Referring to fig. 8, when the shift from the second gear to the first gear is required, the sliding plate 11 is pushed to move the first curved section 31 from the linear clamping groove 24 into the clamping groove 231. Pushing the slide plate 11 causes the first curved section 31 of the connecting member 3 to move in a direction approaching the detent groove 231, during which the elastic member 4 is continuously compressed. When the first bending section 31 touches the first clamping tip 232, the first bending section continues to move along the annular clamping groove 22. When the first bending section 31 moves to one side of the second detent tip 25, it cannot move forward by itself, and the sliding plate 11 cannot move further. At this time, the sliding plate 11 is released, the elastic member 4 rebounds to drive the sliding plate 11 to move reversely, so that the first bending section 31 moves into the clamping groove 231 to switch the gear to one gear.
In one embodiment, when the first curved section 31 moves from the inside of the linear clamping groove 24 to the first clamping point 232, i.e., is about to enter the annular clamping groove 22, in order to allow the first curved section 31 to move in a predetermined direction (clockwise), one side of the first clamping point 232 is provided as a first guide surface 233, and the first guide surface 233 intersects with the axis of the linear clamping groove 24. Thus, when the first curved section 31 moves to the first click tip 232, it contacts the first guide surface 233, and then moves along the first guide surface 233 and gradually enters the annular click slot 22 in a predetermined direction (clockwise).
As shown in fig. 4 to 6, one side of the second catching tip 25 and the outer ring of the annular catching groove 22 form a catching groove 251, and a horizontal straight line passing through the vertex of the catching groove 251 intersects with the catching groove 231. When the first bending section 31 moves to the limit groove 251, the sliding plate 11 cannot be moved forward, and at this time, the elastic member 4 rebounds to drive the sliding plate 11 to move reversely. In this process, the first bending section 31 moves into the catching groove 231 and slides along one side wall of the catching groove 231 until moving to the tip apex angle of the catching groove 231.
In one embodiment, as shown in fig. 6, the second guiding surface 252 is disposed on the other side of the second locking tip 25, and a horizontal straight line passing through the vertex of the locking groove 231 intersects with the second guiding surface 252. When shifting from first gear to second gear, as shown in fig. 7, the sliding plate 11 needs to be pushed to move the first curved section 31 from the detent 231 into the linear detent 24. In this process, in order to allow the first curved section 31 in the detent groove 231 to continue to move in the preset direction (clockwise), after the first curved section 31 is separated from the detent groove 231, the first curved section 31 may touch the second guide surface 252 and continue to move along the second guide surface 252. When the first bending section 31 moves to the farthest end of the annular clamping groove 22, the first bending section 31 cannot move continuously, at this time, the sliding plate 11 is released, the elastic piece 4 rebounds to drive the sliding plate 11 to move reversely, and the sliding plate 11 drives the first bending section 31 to move clockwise along the annular clamping groove 22 until entering into the linear clamping groove 24, so that the gear is switched to the second gear.
Considering that the connecting piece 3 can move up and down, when the distance of the connecting piece 3 moving down is too large, the depth of the first bending section 31 extending into the annular clamping groove 22 is too large, so that the connecting piece 3 touches the clamping block 23, and the connecting piece 3 is blocked. Therefore, in one embodiment, the annular clamping groove 22 is provided with a guiding inclined plane 221, and the guiding inclined plane 221 is located between the clamping groove 231 and the limiting groove 251. When the first bending section 31 moves to the guiding slope 221, if the height of the first bending section 31 is too low, the first bending section 31 can be lifted up after moving along the guiding slope 221, so as to avoid the situation that the connecting piece 3 is jammed.
As shown in fig. 3, a boss 222 is further disposed in the annular clamping groove 22, the boss 222 is disposed between the clamping groove 231 and the second clamping tip 25, one side of the boss 222 is connected with the guiding inclined plane 221, the height of the boss 222 is smaller than the height of the highest point of the guiding inclined plane 221, a top protrusion 234 is disposed on the top wall of the clamping block 23, and the top protrusion 234 is located at one side close to the limiting groove 251. When the first bending section 31 is lifted by the guiding inclined surface 221, the middle section 32 of the connecting piece 3 gradually passes over the top protrusion 234, and when the first bending section 31 moves to the boss 222, the height of the first bending section 31 is suddenly reduced due to the height difference between the boss 222 and the guiding inclined surface 221, so that the middle section 32 of the connecting piece 3 contacts with the top protrusion 234, and the top protrusion 234 limits the position of the middle section 32 of the connecting piece 3, so as to further fix the position of the connecting piece 3.
And the boss 222 and the bottom surface of the annular clamping groove 22 have a height difference, and when the first bending section 31 leaves the clamping groove 231 and the boss 222, the connecting piece 3 falls down, so that the first bending section 31 contacts with the bottom surface of the annular clamping groove 22, the moving direction of the first bending section 31 is limited, and the first bending section 31 is prevented from reentering the clamping groove 231.
As shown in fig. 1, the push button assembly 1 further includes a push button 14, and the push button 14 is fixedly connected to the top wall of the sliding plate 11. The push button 14 can facilitate the operator to push the sliding plate 11 to quickly complete the gear shifting operation. The push button can be fixed on the sliding plate 11 through an integral molding or a colloid adhesion mode.
In one embodiment, the push button assembly 1 further includes a connection block 13, the connection block 13 is mounted on the bottom wall of the sliding plate 11, and one end of the elastic member 4 is connected to the sliding plate 11 through the connection block 13. The connection block 13 protrudes downward so that the connection portion of the slide plate 11 with the elastic member 4 moves downward so that the elastic member 4 is kept as horizontal as possible.
As shown in fig. 2, the gear plate 21 is provided with a receiving groove 26, the receiving groove 26 receives the elastic member 4, and the other end of the elastic member 4 is fixed in the receiving groove 26. The receiving groove 26 can provide the space for the elastic member 4 to compress and rebound on the one hand, and can limit the position of the elastic member 4 on the other hand, prevent the elastic member 4 from contacting with other parts, protect the elastic member 4, and ensure the stability of the compression and rebound of the elastic member 4.
In one embodiment, the connection block 13 protrudes into the receiving groove 26. When the connection block 13 extends into the receiving groove 26, the moving direction of the sliding plate 11 can be limited, so that the sliding plate 11 can only move along the axial direction of the receiving groove 26, and a person can conveniently push the sliding plate 11 to shift gears.
In order to shorten the distance between the sliding plate 11 and the gear plate 21, an avoidance groove is formed in the bottom wall of the gear plate 21, and the insertion hole 12 is formed in the avoidance groove. The relief groove is mainly intended to clear the connecting element 3, precisely the intermediate section 32 of the connecting element 3, so that the slide plate 11 and the gear plate 21 remain as close as possible.
The gear shifting structure of the electric tool provided by the utility model is further described below with reference to specific use cases.
As shown in fig. 7 and 8, when it is necessary to switch from first gear to second gear, the slide plate 11 is first pushed so that the first curved section 31 of the connecting member 3 is away from the detent groove 231. After the first curved section 31 contacts the second detent tip 25 on the annular detent 22, the first curved section 31 moves along the second guide surface 252. When the first bending section 31 moves to the limit position, the sliding plate 11 is released, the elastic member 4 rebounds to drive the sliding plate 11 to move reversely, the first bending section 31 moves into the linear clamping groove 24 along the annular clamping groove 22, the position of the sliding plate 11 is fixed, and the gear is switched to the second gear.
When it is necessary to switch from the second gear to the first gear, the sliding plate 11 is pushed first to move the first curved section 31 of the connecting member 3 in a direction approaching the detent groove 231, and the elastic member 4 is continuously compressed during this process. When the first bending section 31 touches the first clamping tip 232, the first bending section continues to move along the annular clamping groove 22. When the first bending section 31 moves to the limit groove 251, the sliding plate 11 cannot move forward continuously, at this time, the elastic member 4 rebounds one end distance to drive the sliding plate 11 to move reversely, so that the first bending section 31 moves into the clamping groove 231 to fix the position of the sliding plate 11 and switch the gear to one gear.
In the gear shifting structure of the electric tool according to the embodiment of the present utility model, the position of the gear plate 21 needs to be fixed, and meanwhile, the sliding plate 11 is connected to other devices capable of adjusting the gear ratio, specifically, as shown in fig. 1, two clamping pieces 15 may be disposed below the sliding plate 11 of the push-button assembly 1, one end of the gear shifting wire 5 is clamped and fixed by the clamping pieces 15, the other end of the gear shifting wire 5 is connected to the gear assembly 6, so as to control the gear ratio of the gear assembly 6, and after the gear ratio of the gear assembly 6 is changed, the rotation speed and the output power of the rotor in the motor 7 are changed, so that the gear of the electric tool is substantially shifted.

It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching.
