However, the technologies, methods and devices should be considered as part of the description where appropriate. As shown in Fig. 1 - Fig. 8, a connecting structure of the present disclosure is arranged to connect an accessory 3 onto a device main body 1. For example, a battery pack (an accessory) is mounted on a main body of a handheld dust collector.
In some embodiments of the present disclosure, the connecting structure is shown in Fig. 1 and Fig. 6- Fig. 8. The device main body 1 is provided with a locking member 2. The locking member 2 is rotated relative to the device main body 1. The locking member 2 is provided with a first state and a second state through a rotation of the locking member 2. In the first state, the locking member 2 limits a movement of the accessory 3 relative to the device main body 1. In the second state, the locking member 2 unlocks the movement of the accessory 3 relative to the device main body 1. In this way, the accessory 3 needs to move relative to the device main body 1 only when the accessory 3 is assembled on or disassembled from the device main body 1, with convenient assembling and disassembling. Moreover, a box body and a cover body for mounting the accessory are prevented from being disposed on the device main body 1, and accordingly the structure is simpler.
As shown in Fig. 1 and Fig. 6-Fig. 8, in some embodiments, the device main body 1 includes a handle 11, a beam 12 and a support column 13. The beam 12 and the handle 11 are disposed with an included angle. A middle part of a first end of the beam 12 is connected with the handle 11. Two sides of the middle part of the first end of the beam 12 are provided with two bulges 121, and a second end of the beam 12 is connected with the support column 13.
A bearing platform 14 is disposed on the support column 13 and located at a lower side of the beam 12. The bearing platform 14 is constructed as a first bulge 141 and extends towards the first end of the beam 12. In some embodiments of the present disclosure, the first bulge 141 includes a base plate 1411 and side plates 1412 connected with the base plate 1411 and located on two sides of the base plate 1411. In some embodiments, the support column between the two side plates 1412 is provided with a groove 1413. An upper wall of the groove 1413 inclines towards a direction far away from the accessory 3 in an assembling state in a direction from a position far away from the base plate 1411 to a position of the base plate 1411.
As shown in Fig. 2 and Fig. 6 -Fig. 8, in some embodiments, the accessory 3 includes a groove structure 31 disposed on an upper part thereof, and a second end of the groove structure 31 is disposed as an opening 311. When the battery pack serves as the accessory 3, a first end of the groove structure 31 is provided with a wiring portion 32. The wiring portion 32 is used to provide the device main body 1 with power. Two grooves 312 cooperated with the bulge 121 are configured on two sides of the wiring portion 32 and located on a side wall of the groove structure 31. In other embodiments, the first end of the beam 12 is further provided with the groove, and the accessory 3 is provided with the bulge that is capable of being cooperated with the groove.
An end part of the accessory 3 located on the second end of the groove structure 31 is provided with a second bulge 33. In the assembling state, the beam 12 is embedded on the groove structure 31, the bulge 121 is inserted into a corresponding groove 312, and the second bulge 33 is supported on the base plate 1411. In this way, the accessory 3 is suspended on the device main body 1, so that configuration of a cavity structure for accommodating the accessory is omitted, and the structure is simpler.
As shown in Fig. 3 and Fig. 5 -Fig. 8, in some embodiments, the locking member 2 includes a first arm 21 and a second arm 22 that are connected with an included angle. Two ends of a connecting position of the first arm 21 and the second arm 22 are provided with a pivoting portion 23 respectively, and the pivoting portion 23 includes a hinge shaft 231. The device main body 1 includes a lining structure 15, and one end of the lining structure 15 is provided with a mounting groove 151. A groove wall of the mounting groove 151 is provided with an axle hole 1511, and the locking member 2 is mounted on the lining structure 15 by mounting the hinge shaft 231 in the axle hole 1511. In other embodiments, the pivoting portion further includes the axle hole, and the device main body includes a hinge shaft cooperated with the axle hole.
In some embodiments, the first arm 21 includes a first block 211 and a first rod 212 that are integrally formed, and the second arm 22 includes a second block 221 and a second rod 222 that are integrally formed. The first rod 212 is connected with the second rod 222. Through the first arm 21 formed by the first block 211 and the first rod 212 and the second arm 22 formed by the second block 221 and the second rod 222, structural strength is ensured, and a material is reduced.
As shown in Fig. 5, in some embodiments, a biasing member 4, for example, a spring is disposed between the second block 221 and the lining structure 15. As shown in Fig. 3, a side surface of a side of the second block 221 facing the lining structure 15 is provided with a first mounting column 2211. As shown in Fig. 4, the lining structure 15 is provided with a second mounting column 1512, and the spring is disposed on the first mounting column 2211 and the second mounting column 1512.
In some embodiments, the handle 11 is a tubular structure. The lining structure 15 is fixedly mounted in a hollow cavity of the handle 11. In some embodiments, the lining structure 15 is mounted on the handle 11 in an interference fit manner. The beam 12 is provided with an accommodating hole 122, and a gap 111 is formed by a side wall of a part of the accommodating hole 122 passing through the tubular structure. In this way, in the assembling state, the first arm 21 is embedded into the accommodating hole 122, a partial structure of the second arm 22 is exposed outside through the gap 111, and an operating portion 223 is formed by a side surface of a side of the partial structure of the second arm 22 opposite to a side on which the spring is mounted. It is apparent that the operating portion 223 is exposed on the handle 11 through the gap 111, thereby facilitating a user to operate.
As shown in Fig. 3 and Fig. 6, in some embodiments, the first arm 21 includes a first inclined plane 213, and the first inclined plane 213 is disposed on the first block 211 and the first rod 212. In the assembling state, the first inclined plane 213 gradually inclines towards a side on which the accessory 3 is assembled from the pivoting portion 23 to a free end of the first arm 21.
In some embodiments, the second end of the groove structure 31 of the accessory 3 is provided with a clamping and stopping structure 34. As shown in Fig. 2, in some embodiments, the clamping and stopping structure 34 is constructed to a bulge disposed on the accessory 3, and the clamping and stopping structure 34 includes a limiting surface 341 and a second inclined plane 342. In the assembling state, a direction of inclination of the second inclined plane 342 is consistent with that of the first inclined plane 213, and an end of the second inclined plane 342 at a high position is connected with the limiting surface 341. When the accessory 3 is mounted into the device main body 1, namely, when the accessory 3 moves along the beam 12 relative to the device main body 1, a free end of the bulge of the clamping and stopping structure 34 pushes the first inclined plane 213, so that the accessory 3 moves successfully. When the accessory 3 moves to a position that the free end of the bulge of the clamping and stopping structure 34 is departed from the pushing of the first inclined plane 213, the locking member 2 resets under an action of the spring, so that the free end of the first arm 21 abuts against the limiting surface 341, the movement of the accessory 3 relative to the device main body 1 is limited, and accordingly the accessory 3 is reliably mounted on the device main body 1.
Some embodiments of the present disclosure provide the connecting structure, when the accessory 3 needs to be mounted on the device main body 1, the accessory 3 is made to slide along the beam 12 first. During sliding, the beam 12 is embedded into the groove structure 31, and the groove structure 31 guides the accessory 3 to slide, as to ensure that the accessory 3 successfully slide in place. Meanwhile, the free end of the bulge of the clamping and stopping structure 34 pushes the first inclined plane 213 of the first arm 21, so that the locking member 2 rotates by taking the hinge shaft 231 as a rotation shaft.
When the free end of the clamping and stopping structure 34 pushes the first inclined plane 213, the spring is in a state of compression. When the accessory 3 continues to slide to the free end of the clamping and stopping structure 34 and is departed from the first inclined plane 213, the locking member 2 rotates under an action of the spring, so that limitation on the limiting surface 341 of the clamping and stopping structure 34 is formed by the free end of the first arm 21. Meanwhile, the bulge 121 is mounted in the groove 312 in a clamping manner, and the second bulge 33 is supported on the base plate 1411, so that the accessory 3 is ensured to be suspended at a lower part of the device main body 1.
When the accessory 3 needs to be disassembled from the device main body 1, the operating portion 223 exposed at a position of the gap 111 of the handle 11 needs to be pressed only. When the operating portion 223 is pressed, the operating portion 223 extrudes the spring, so that the locking member 2 rotates, as to ensure that the free end of the first arm 21 is departed from the limitation on the limiting surface 341 of the clamping and stopping structure 34. In this way, the accessory 3 slides out of the device main body 1 successfully.
Some embodiments of the present disclosure further provide a handheld dust collector, the handheld dust collector includes a dust collector main body and a battery pack. The battery pack is connected with the dust collector main body through the abovementioned connecting structure. Herein, an accessory includes the battery pack. As a device main body, the dust collector main body is connected with the accessory including the battery pack through the connecting structure.
It is easy for those skilled in the art to understand that all of the abovementioned embodiments are freely combined and superimposed without conflict.
