FIG. 1 and FIG. 2 show a toy telescopic device 10 according to some embodiments of the present disclosure. The toy telescopic device 10 includes a grip assembly 1, a telescopic assembly 2 and a power assembly 3. It is understandable that the shape of the grip assembly 1 may be set flexibly. The grip assembly 1 is configured for a user to hold, which may be shaped as a plastic shell by injection molding to install the telescopic assembly 2 and the power assembly 3. The telescopic assembly 2 may be extended and retracted slidably. The power assembly 3 is configured to drive the telescopic assembly 2 to extend and retract.
As shown in FIG. 1 to FIG. 3 , the telescopic assembly 2 includes a plurality of telescopic layers 21 slidably arranged on the grip assembly 1, each telescopic layer 21 is sleeved into one another, and the telescopic layer 21 positioned on an innermost side is provided with a connecting position 211.
It is understandable that the telescopic layers 21 are multiple in number. Each telescopic layer 21 is configured to be sleeved into one another from the inside out. Two adjacent telescopic layers 21 can slide relative to one another. A common sliding limit structure available in the existing technologies may be provided between adjacent telescopic layers 21, to restrict a sliding limit position of each telescopic layer 21. The connecting position 211 is configured to be connected to the power assembly 3, whereby the power assembly 3 can drive the telescopic layer 21 positioned on the innermost side among the telescopic layers 21 to slide. Of course, in the retracting direction, the adjacent telescopic layers 21 also have a limit structure provided therebetween. The limit structure may also be a step, a protrusion or other limit structures available in the existing technologies, whereby a telescopic layer 21 on an inner side can drive a telescopic layer 21 on an outer side to slide and retract simultaneously.
As shown in FIG. 2 to FIG. 6 , the power assembly 3 includes a self-resetting member 31 arranged on the grip assembly 1, a driving member 32 arranged on the grip assembly 1, and a clutch member 33 moveably arranged between the self-resetting member 31 and the driving member 32. The self-resetting member 31 is connected to the connecting position 211 in a driving manner, and the clutch member 33 is connected to the driving member 32 in a driving manner.
It to be noted that the connecting position 211 and the self-resetting member 31 may be configured to be connected by means of snap-fit connection, insertion, screwing, magnetic attraction or welding, etc.
When the clutch member 33 moves relative to the grip assembly 1 and abuts against the self-resetting member 31, the driving member 32 drives the self-resetting member 31 by means of the clutch member 33, whereby the self-resetting member 31 drives the telescopic layer 21 positioned on the innermost side to extend out, thereby driving the remaining telescopic layers 21 to slidably extend out. When the clutch member 33 is separated from the self-resetting member 31, the self-resetting member 31 is released, whereby driving each telescopic layer 21 to slidably retract into the grip assembly 1.
It is understandable that the self-resetting member 31 has an automatic resetting function. The self-resetting member 31 is of an existing technology, which specifically may be components with a resetting rotation function in a spinning direction, also may be components with a resetting sliding function in a sliding direction. The driving member 32 is configured to output a torque. The driving member 32 may be an electric motor. The clutch member 33 is configured to transmit the torque from the driving member 32. The position of the clutch member 33 on the grip assembly 1 may be adjusted by means of depressing or turning, etc., specifically depending on the design structure of the product and the application requirements. The depressing mode may be implemented by means of linear moving elements such as switches, and the turning mode may be implemented by means of rotatable elements such as knobs.
When in use, the position of the clutch member 33 is adjusted to abut against the self-resetting member 31, meanwhile the clutch member 33 is also connected to the driving member 32 in a driving manner, whereby the torque output by the driving member 32 will be transmitted to the self-resetting member 31 by means of the clutch member 33 to overcome the self-resetting force of the self-resetting member 31, so that the self-resetting member 31 drives the telescopic layer 21 on the innermost side to slidably extend out. Then, a telescopic layer 21 extended out on an inner side will drive a telescopic layer 21 on an outer side to further extend out slidably. If to a limit position, the sliding is restricted by the limit structure on the telescopic layer 21. The limit structure between two adjacent telescopic layers 21 enables the telescopic layer 21 on the inner side to drive the telescopic layer 21 on the outer side to slidably extend out.
When it is needed to retract each telescopic layer 21, the position of the clutch member 33 is adjusted to be separated from the self-resetting member 31, whereby the torque of the driving member 32 cannot be transmitted to the self-resetting member 31. Then, the self-resetting member 31 performs self-resetting rotation and drives the telescopic layer 21 on the innermost side to slide toward the direction to retract into the grip assembly 1, whereby the telescopic layer 21 on the inner side drives the telescopic layer 21 on the outer side to slidably retract, so that each telescopic layer 21 is slidably received into the grip assembly 1.
It is to be noted that whether the torque output of the driving member 32 is stopped during the extending process, or the clutch member 33 abuts against the self-resetting member 31 again during the retracting process, as long as the clutch member 33 abuts against the self-resetting member 31, the self-resetting operation of the self-resetting member 31 is locked and limited, and each telescopic layer 21 will remain at its current position.
As shown in FIG. 4 to FIG. 6 , in some embodiments of the toy telescopic device 10, the clutch member 33 includes an installation bracket 331 moveably arranged on the grip assembly 1, a friction wheel 332 rotatably arranged on the installation bracket 331 and a driven gear 333 connected to the friction wheel 332 in a driving manner.
The driving member 32 is provided with a driving gear 321 that is engaged with the driven gear 333, the installation bracket 331 drives the friction wheel 332 to move relative to the grip assembly 1, whereby the friction wheel 332 abuts against or gets away from the self-resetting member 31.
As shown in FIG. 4 to FIG. 6 , the installation bracket 331 is configured to support the friction wheel 332 in rotating. The moving mode of the installation bracket 331 on the grip assembly 1 may be configured as sliding or rotating. The installation bracket 331 is configured to drive the friction wheel 332 to move toward a direction close to or far away the self-resetting member 31. The friction wheel 332 is configured to drive the self-resetting member 31 to operate by means of a friction force, that is, the friction wheel 332 is configured to transmit the torque to the self-resetting member 31. The driving gear 321 and the driven gear 333 may be configured to always keep engaged with one another, that is, even when the installation bracket 331 drives the friction wheel 332 to slide to different positions, the driven gear 333 will always be engaged with the driving gear 321, and the torque of the driving member 32 will always be transmitted to the driven gear 333.
It is to be noted that the driven gear 333 and the friction wheel 332 may be configured to have a coaxial arrangement therebetween, whereby achieving a same rotational angular velocity. Of course, it can also be that the driven gear 333 drives a roller on the installation bracket 331 to rotate, and then the roller drives the friction wheel 332 to rotate, wherein the roller and the friction wheel 332 may be configured to abut against one another with surfaces.
As shown in FIG. 4 to FIG. 6 , in some embodiments of the toy telescopic device 10, the clutch member 33 further includes a reset spring 334 that is connected to the installation bracket 331 in a driving manner. The reset spring 334 provides an acting force driving the installation bracket 331 to move relative to the telescopic assembly 2, whereby the installation bracket 331 drives the friction wheel 332 to move toward a direction close to the self-resetting member 31.
It is understandable that the arrangement of the reset spring 334 enables the friction wheel 332 to always tend to abut against the self-resetting member 31, whereby the reset spring 334, when released onto the installation bracket 331, can cause the installation bracket 331 to drive the friction wheel 332 to move and abut against the self-resetting member 31. In this way, during the process of extending or retracting of each telescopic layer 21, the operation can be stopped at any time so as to keep the current extending state.
As shown in FIG. 4 to FIG. 6 , in some embodiments of the toy telescopic device 10, the clutch member 33 further includes a clutch button 335 slidably arranged on the grip assembly 1 and a button spring 336 arranged on the clutch button 335. When the clutch button 335 moves abutting against the installation bracket 331, the installation bracket 331 drives the friction wheel 332 to move toward a direction far away the self-resetting member 31, and the button spring 336 provides an acting force driving the clutch button 335 to slide toward a direction far away the installation bracket 331.
It is understandable that the clutch button 335 is configured for a user to operate. The clutch button 335 can be configured as a button available in the existing technologies. The button spring 336 is configured to drive the clutch button 335 to slide for resetting.
When in use, while the clutch button 335 is being pressed down, the clutch button 335 overcomes the elasticity of the button spring 336 to move, and the clutch button 335 moves abutting against the installation bracket 331, whereby the installation bracket 331 drives the friction wheel 332 to move toward a direction far away the self-resetting reel relative 31. When the clutch button 335 is released, the clutch button 335 slides for resetting under the action of the button spring 336, so that the clutch button 335 is available for use in a next depressing.
As shown in FIG. 4 to FIG. 6 , in some embodiments of the toy telescopic device 10, the self-resetting member 31 includes a seat body 311 arranged inside the grip assembly 1, a self-resetting reel 312 rotatably arranged on the seat body 311 and a tape 313 wound around the self-resetting reel 312.
The self-resetting reel 312 drives the tape 313 to wind back onto the self-resetting reel 312 during the resetting rotation process; and the clutch member 33 moves toward a direction close to or far away the self-resetting reel 312 relative to the grip assembly 1.
It is understandable that the seat body 311 is configured to support the self-resetting reel 312 in rotating. The self-resetting reel 312 is configured for the tape 313 to wind around. The tape 313 is configured to drive the telescopic layers 21 to slide and retract into the grip assembly 1 during the winding process and is configured to drive the telescopic layers 21 to slide and extend out during the unwinding process. The clutch member 33 may transmit the torque to the self-resetting member 31 by abutting against the tape 313 in a winding state or the self-resetting reel 312, as long as the torque of the driving member 32 can be transmitted to the self-resetting member 31 by means of the clutch member 33.
It is to be noted that the resetting rotation function of the self-resetting reel 312 is available in the existing technologies, which specifically may refer to the auto-winding measuring tapes available in the existing technologies. The tape 313 may be configured as a metal strip.
As shown in FIG. 3 to FIG. 6 , in some embodiments of the toy telescopic device 10, the connection position 211 has a snap slot 212 (as shown in FIG. 3 ) formed thereon, the tape 313 has an end part provided with a snap-fit part 314, and the snap-fit part 314 is inserted into the snap slot 212.
It is understandable that the snap-fit part 314 is inserted and tightly clamped into the snap slot 212, whereby the tape 313 can drive the telescopic layer 21 to slide by means of the snap-fit part 31.
As shown in FIG. 3 , in some embodiments of the toy telescopic device 10, the power assembly 3 further includes a limit switch 34 arranged on the grip assembly 1, and the telescopic layer 21 positioned on an outermost side abuts against the limit switch 34 to turn on or off the limit switch 34 when slidably extending out.
It is understandable that when each telescopic layer 21 slidably extends out together to the limit position, the telescopic layer 21 will abut against the limit switch 34, whereby causing the limit switch 34 to turn on or off so as to control the driving member 32 to stop outputting torque. In this way, damage to the parts can be avoided.
As shown in FIG. 3 , in some embodiments of the toy telescopic device 10, each telescopic layer 21 is in a tubular shape, the telescopic layer 21 positioned on the innermost side is sealed on one end, and each telescopic layer 21 is provided with a sliding limit step 213.

Further, the grip assembly 1 can also be provided with a limit structure to limit the telescopic layer 21 on the outermost side, whereby preventing the telescopic layer 21 on the outermost side directly falling off the grip assembly 1.
As shown in FIG. 2 , in some embodiments of the toy telescopic device 10, the toy telescopic device 10 further includes a power supply 4 and a switch 5. The power supply 4 is electrically connected to the driving member 32 through the switch 5.
It is understandable that the power supply 4 is configured to output an electric energy. The switch 5 is configured to control the connection of electric energy between the power supply 4 and the driving member 32.
In some embodiments of the toy telescopic device 10, the toy telescopic device 10 further includes a lighting assembly (not shown in the figures). The lighting assembly includes at least one lighting element that faces toward the telescopic layer 21.
It is understandable that the lighting element can be electrified to emit light, and the light emitted by the lighting element will cause the telescopic layers 21 to light. In this way, the product can have an illumination function. Preferably, the lighting element is configured to illuminate the telescopic layers 21 from inside the grip assembly 1.
