[0033] The first embodiment of the present application provides a range-adjustable ejection device for ejecting materials with an adjustable range, which can be intelligently adjusted to a specified range without the need for manual operation by the user. Specifically, the range-adjustable ejection device includes an upper shell and a lower shell, and an ejection device, a gear limit device, a driving device, and an excitation device are provided between the upper shell and the lower shell. The ejection device is used to eject materials with a specified range; the driving device is used to adjust the range of the ejection device and also to drive the excitation device; the excitation device is used to control the gear limit device to limit and excite the ejection device based on the driving of the driving device. Specifically, the excitation device controls the gear limit device to limit the ejection device, so that the ejection device can be stably in a certain gear and the ejection device will only eject when the gear limit device is excited, thereby ensuring the stability of the ejection device during the range adjustment process. The gear limiting device is used to limit and activate the range gear of the ejection device based on the control of the activating device; specifically, the gear limiting device limits the range gear of the ejection device, which means that the range of the ejection device is limited to a certain gear and the ejection device is limited to remain in the ejection loaded state; the gear limiting device activates the range gear of the ejection device, which means that the gear limiting device stops limiting the ejection device, so that the ejection device can eject according to the range corresponding to the gear defined before activation. It can be understood that in this application, the range of the ejection device is adjusted by the driving device, and the activation control of the ejection of the ejection device is also realized based on the driving device. Only a single driving method is used to simplify the driving structure of the ejection device and reduce the driving cost. At the same time, based on the combination of multiple devices such as the gear limiting device, the driving device and the activating device, the range adjustment of the ejection device in multiple gears is realized, thereby optimizing the user experience.

[0034] In a second embodiment of the present application, a range-adjustable ejection device is provided, wherein the ejection device comprises a ejection rod and an energy storage spring. One end of the ejection rod abuts the energy storage spring, while the other end of the ejection rod serves as the ejection end of the ejection device, used to eject material. Specifically, the abutment between one end of the ejection rod and the energy storage spring refers to an interaction force between the two ends. The ejection rod achieves its ejection function based on the elastic force provided by the compressed energy of the energy storage spring, and the driving device adjusts the ejection device's range by adjusting the compression of the energy storage spring. The abutment between one end of the ejection rod and the energy storage spring can be, but is not limited to, fixed or removable. In the ejection device provided in this embodiment, the ejection device is designed as a combination of an energy storage spring and an ejection rod, achieving the ejection function based on a simple energy storage spring. Depending on the weight of the material actually ejected by the ejection device, energy storage springs with different elastic coefficients can be used to meet the required ejection range.

[0035] like Figure 1 As shown, Figure 1 The exploded view of the range-adjustable catapult device is shown in the video. Figure 1 One end of the middle ejection rod 500 contacts the energy storage spring 1000 . Figures 8 and 9 It shows that the energy storage spring 1000 is compressed and stored. Figure 7 The diagram shows the position of the ejection rod when the energy storage spring 1000 is in an extended state.

[0036] In the third embodiment of the present application, the ejection device with adjustable range is provided, wherein the ejection device further includes: N-1-step meshing teeth for engaging with the driving device, and based on the meshing of the driving device, the ejection device compresses the energy storage spring, wherein N is an integer greater than 1; specifically, the N-1-step meshing teeth are provided at one end of the bottom of the ejection rod near the ejection end, and the driving device adjusts the compression of the energy storage spring by meshing with the N-1-step meshing teeth step by step. It can be understood that when the meshing teeth engaged by the driving device are higher, the compression of the energy storage spring is greater, the compressed energy stored in the energy storage spring is greater, and the range of the ejection device is longer. This embodiment provides an ejection device with multi-step meshing teeth, which provides an adjustment basis for the ejection device to have multiple ejection strokes, so that the ejection rod has sufficient sliding stroke.

[0037] In the fourth embodiment of the present application, the range-adjustable ejection device provided by the drive device includes: a drive motor and a drive gear with N-step drive teeth; wherein the drive motor is electrically connected to the drive gear, and the drive motor provides power for the rotation of the drive gear. The drive gear with N-step drive teeth rotates to cause the drive teeth to engage with the meshing teeth of the ejection device, and the expansion and contraction amount of the energy storage spring is regulated by switching the number of meshing steps between the two. The drive motor is disposed on the outer surface of the upper shell or between the upper shell and the lower shell.

[0038] Specifically, the diameter of the driving teeth increases step by step as the order of the driving teeth increases, and the diameter of the meshing teeth decreases step by step as the order of the meshing teeth increases. The first-order driving teeth are adapted to mesh with the first-order meshing teeth, the second-order driving teeth are adapted to mesh with the second-order meshing teeth... and the N-1th-order driving teeth are adapted to mesh with the N-1th-order meshing teeth. In particular, the diameter of the N-1th-order driving teeth is the same as the diameter of the N-1th-order driving teeth, and the N-1th-order driving teeth are used to drive the excitation device. In this embodiment, the diameter of the driving teeth and the diameter of the meshing teeth are designed to change with the increase in the order, so that when the driving gear rotates in the opposite direction, the driving teeth and the meshing teeth can completely disengage from the meshing state. It can be understood that when the driving gear rotates in the opposite direction, the N-1th-order driving teeth of the driving gear and the N-1th-order meshing teeth of the ejection device do not mesh with each other and do not touch each other. In this application, the direction in which the drive gear rotates and the meshing teeth of the ejection device are engaged is defined as the forward direction, and the reverse direction is defined as the reverse direction. For example, when the forward direction is the clockwise rotation of the drive gear, the reverse direction is the counterclockwise rotation of the drive gear. Conversely, when the forward direction is the counterclockwise rotation of the drive gear, the reverse direction is the clockwise rotation of the drive gear. When the drive gear rotates in the forward direction, the drive teeth of the drive gear and the meshing teeth of the ejection device are meshed step by step with the rotation, and when the drive gear rotates in the reverse direction, the drive teeth of the drive gear and the meshing teeth of the ejection device are disengaged. The range-adjustable ejection device provided in this embodiment indirectly controls the rotation of the drive gear by controlling the power supply of the drive motor, thereby achieving control of the ejection range of the ejection device.

[0039] An embodiment of the present application provides a range-adjustable ejection device, including: Figure 3 and Figure 4 Schematic diagram of the drive unit and ejection rod. Figure 3 The bottom of the ejection rod is provided with a middle two-stage meshing tooth, specifically including a first-stage meshing tooth 501 and a second-stage meshing tooth 502. The diameter of the first-stage meshing tooth 501 is larger than the diameter of the second-stage meshing tooth 502. Figure 4 The driving device shown includes three-stage driving teeth, specifically including first-stage driving teeth 601, second-stage driving teeth 602 and third-stage driving teeth 603. The diameter of the first-stage driving teeth 601 is smaller than the diameter of the second-stage driving teeth 602, while the diameter of the second-stage driving teeth 602 is the same as the diameter of the third-stage driving teeth 603. Figure 8 As shown, when the driving gear rotates and engages with the meshing teeth of the ejection device, the first-stage meshing teeth 501 are adapted to mesh with the first-stage driving teeth 601. Figure 9 As shown, when the driving gear further rotates and further engages with the meshing teeth of the ejection device to further compress the energy storage spring, the second-stage meshing teeth 502 are adapted to engage with the second-stage driving teeth 602, and the first-stage meshing teeth 501 are disengaged from the first-stage driving teeth 601.

[0040] In the fifth embodiment of the present application, the range-adjustable ejection device provided by the present invention comprises an excitation device comprising a first excitation tooth and a second excitation tooth. The first excitation tooth is driven to rotate by the Nth-order drive tooth of the drive gear, thereby driving the rotation of the second excitation tooth, so that the drive gear indirectly drives the second excitation tooth via the first excitation tooth. The second excitation tooth is used to control the limiting and excitation of the gear limit device. Specifically, the limiting of the gear limit device refers to the gear limit device limiting the compression amount of the energy storage spring of the ejection device, so that the compression amount of the energy storage spring is maintained; the excitation of the gear limit device refers to the gear limit device canceling the compression amount of the energy storage spring of the ejection device, so that the energy storage spring performs an ejection action based on the energy stored in the original compression, thereby completing the ejection of the ejection device. The range-adjustable ejection device provided by this embodiment is provided with an excitation device having two excitation teeth, so that the drive gear can indirectly control the limiting and excitation of the ejection device by the gear limit device, thereby realizing a single drive mechanism to complete the linkage control of multiple modules, reducing the drive cost while ensuring the driving effect.

[0041] In the sixth embodiment of the present application, the ejection device with adjustable range is provided, wherein the ejection device further comprises: a plurality of gear hooks; wherein the plurality of gear hooks are arranged at the bottom of the ejection rod near one end of the energy storage spring; the gear limit device limits the range gear of the ejection device by engaging with the gear hook, so that the compression amount of the energy storage spring of the ejection device is limited. Specifically, this embodiment adopts a plurality of gear hooks, so that each gear hook indicates a different compression amount of the energy storage spring, and also indicates a plurality of ejection stroke gears of the ejection device. The gear limit device adjusts the different ejection strokes of the ejection device by engaging and limiting with different gear hooks.

[0042] In the seventh embodiment of the present application, the range-adjustable ejection device provided, the gear limit device includes: a limit mechanism and a gear spring; wherein the limit mechanism is used to engage with the gear hook to limit the ejection gear of the ejection device; the gear spring is used to adjust the engagement state of the limit mechanism and the gear hook. Specifically, the bottom of the limit mechanism is connected to the gear spring, and when the second excitation tooth of the excitation device rotates to adjust the limit mechanism, the gear spring is compressed. When the compression amount of the gear spring reaches a preset compression amount, the limit mechanism and the gear hook are completely disengaged, and the energy storage spring of the ejection device is ejected based on the energy storage auxiliary ejection rod. It should be noted that the "completely disengaged state" described in this embodiment refers to the positional state between the limiting mechanism and the gear hook when the compression amount of the gear spring is greater than or equal to the preset compression amount. When the compression amount of the gear spring is greater than or equal to the preset compression amount, a certain distance is maintained between the limiting mechanism and the gear hook, the gear hook is not restrained, and the energy storage spring of the ejection device can provide power for the ejection of the ejection device when the drive gear is not engaged with the meshing teeth and the limiting mechanism is not engaged with the gear hook. The ejection device provided in this application can only be ejected when the drive gear is not engaged with the meshing teeth and the limiting mechanism is not engaged with the gear hook. If the drive gear is engaged with the meshing teeth and / or the limiting mechanism is engaged with the gear hook, the ejection device of the ejection device is restrained and the energy storage spring stores energy for the ejection stroke of the ejection device.

[0043] An embodiment of the present application provides a range-adjustable ejection device including: Figure 1 The excitation device 700, the limiting mechanism 900 and the shift spring 800 are shown. Figure 3 As shown, the bottom of the ejection rod 500 is provided with a plurality of gear hooks 503, and the gear hooks 503 are engaged and limited by the limiting mechanism 900, so that the ejection gear of the ejection device can be adjusted by the engagement and limit. Figure 7 and Figure 9 As shown, the excitation device includes a first excitation tooth 701 and a second excitation tooth 702. The third-stage driving tooth 603 of the driving gear is used to drive the rotation of the first excitation tooth 701, and the rotation of the first excitation tooth 701 indirectly drives the rotation of the second excitation tooth 702. The rotation of the second excitation tooth 702 causes the limiting mechanism 900 to be limited and adjusted, so that the gear spring 800 is compressed. Figure 7 The middle position hook 503 is completely out of engagement with the limiting mechanism 900, and the energy storage spring of the ejection device assists the ejection rod to eject. Figure 9 The middle gear hook 503 is engaged with the limit hook 900 , and the compression amount of the energy storage spring of the ejection device is limited.

[0044] In the range-adjustable ejection device provided in the eighth embodiment of the present application, the limiting mechanism includes a first limiting buckle and a second limiting buckle; wherein the first limiting buckle is used to engage with the gear hook to enable the limiting mechanism to limit the range gear of the ejection device; the second limiting buckle is used to conflict with the second excitation tooth of the excitation device when driving the limiting mechanism, so that the second excitation tooth compresses the gear spring through the conflict to achieve control of the compression amount of the gear spring. In this embodiment, by providing the first limiting buckle and the second limiting buckle in the limiting mechanism, the limiting mechanism can not only limit the ejection gear of the ejection device, but also achieve excitation control of the ejection of the ejection device.

[0045] In the ninth embodiment of the present application, the ejection device with adjustable range is provided, and the ejection device further includes: a detection switch; wherein the detection switch is used to detect the ejection state of the ejection device. Specifically, the ejection device with adjustable range of the present application controls the operation of the driving device according to the ejection state of the ejection device obtained by the detection switch; for example, when the detection switch detects that the ejection device is in a non-ejection state, the ejection device controls the rotation of the driving device so that the driving teeth engage with the engaging teeth, the gear hook of the ejection device is adjusted to engage with the first limit buckle, and the ejection gear of the ejection device is adjusted so that the ejection device can complete the corresponding ejection stroke. In the present application, the detection switch can be, but is not limited to, a toggle detection switch, a touch switch, a micro switch, or other switches with detection functions. In the ejection device with adjustable range provided in one embodiment of the present application, such as Figure 2 As shown, the detection switch 300 is arranged on the outer surface of the upper shell.

[0046] In the ejection device with adjustable range provided in the tenth embodiment of the present application, the limiting mechanism further includes: a third limiting buckle. The third limiting buckle is used to trigger the detection switch. Specifically, the third limiting buckle triggers the detection switch when the compression amount of the gear spring reaches a preset compression amount. When the detection switch is triggered by the third limiting buckle, it indicates that the ejection device is in the ejection launch state. Specifically, the ejection state of the ejection device in the present application includes: an ejection launch state and an ejection loading state; wherein, when the ejection device is in the ejection launch state, the driving teeth of the driving device are disengaged from the meshing teeth, and the first limiting buckle of the gear limiting device is disengaged from the gear hook; when the ejection device is in the ejection loading state, at least the driving teeth of the driving device are engaged with the meshing teeth or at least the first limiting buckle is engaged with the gear hook. In the ejection device provided in this embodiment, a third limiting buckle is provided in the limiting mechanism, and the third limiting buckle moves as the second limiting buckle is driven and moved by the second excitation tooth, and the first limiting buckle engages or disengages with the gear hook as the second limiting buckle is driven and moved by the second excitation tooth. Therefore, the movement of the third limiting buckle can reflect the engagement or disengagement of the first limiting buckle and the gear hook. The second excitation tooth is driven by the movement of the first excitation tooth, and the first excitation tooth is driven by the rotation of the driving gear. It can be understood that the driving state of the second excitation tooth reflects the rotation state of the driving gear. When the driving gear drives the first excitation tooth, it means that the 1st-order driving teeth to the N-1th-order driving teeth on the driving gear are all disengaged from the engaging teeth. Based on the above control logic, the detection switch can obtain the ejection state of the ejection device based on the third limiting buckle.

[0047] like Figure 5 As shown, the limiting mechanism 900 includes a first limiting buckle 903, a second limiting buckle 902 and a third limiting buckle 901; specifically, in combination with Figure 9 As shown, the first limiting buckle 903 is used to engage with the gear hook 503 to maintain the compression of the energy storage spring 1000 to achieve range limitation of the ejection device; the second limiting buckle 902 is used to be excited by the rotation of the second exciting tooth 702, thereby controlling the compression of the gear spring 800. Based on the control of the compression of the gear spring 800, the engagement state of the first limiting buckle 903 and the gear hook 503 is controlled. When the first limiting buckle 903 and the gear hook 503 are in a completely disengaged state, the compression of the energy storage spring 1000 is not limited, and the energy storage spring 1000 uses its original energy storage capacity to supply the ejection rod 500 for ejection.

[0048] In the range-adjustable ejection device provided in the eleventh embodiment of the present application, a mating opening is provided on the upper shell, a detection switch is disposed on the outer surface of the upper shell, and the third limit buckle extends from the interior of the upper shell to the exterior of the upper shell through the mating opening to trigger the detection switch. It is understood that a portion of the limit mechanism is exposed outside the upper shell. This embodiment reduces the space required between the upper and lower shells by providing a mating opening on the upper shell and disposing the detection switch on the outer surface of the upper shell.

[0049] Combine Figure 2 and Figure 9 As shown, the third limit buckle 901 is used to trigger the detection switch 300. When the gear spring 800 is compressed by the control of the second limit buckle 902, the third limit buckle 901 moves with the movement of the second limit buckle 902 to complete the triggering of the detection switch 300 by the third limit buckle 901. Figure 6 As shown, the third limit buckle 901 is exposed to the upper shell through the matching opening 103 on the surface of the upper shell, thereby triggering the detection switch 300 set on the outer surface of the upper shell. The triggering method of the detection switch 300 by the third limit buckle 901 varies depending on the type of the detection switch 300, and can be but not limited to toggle triggering, touch triggering, light touch triggering, etc.

[0050] In the ejection device with adjustable range provided in the twelfth embodiment of the present application, the limiting mechanism also includes a limiting gear. Specifically, the limiting baffle is used to limit the moving direction of the first limiting buckle, the second limiting buckle, the third limiting buckle and the gear spring, to prevent the second limiting buckle from being offset in its moving direction after being limited by the second excitation tooth, thereby affecting the accuracy of the engagement between the first limiting buckle and the gear hook. Figure 6 As shown, the limiting mechanism includes a limiting gear 104, which is mainly used to limit the moving direction of the second limiting buckle 902 after being driven by the second excitation tooth 702, so that the movement of the second limiting buckle 902 can enable the gear spring 800 to maintain vertical compression, and there will be no distortion in the compression direction of the gear spring 800 due to the offset of the moving direction of the second limiting mouth 902.

[0051] In the thirteenth embodiment of the present application, a range-adjustable ejection device is provided, wherein a sliding groove is provided on the inner surface of the lower housing, and a raised slide rail is provided on the ejection device. The raised slide rail matches the sliding groove, and the ejection device slides within the sliding groove based on the raised slide rail. The ejection device provided in this embodiment reduces the sliding contact surface between the ejection device and the lower housing by providing the sliding groove and the raised slide rail, thereby reducing friction between the ejection device and the lower housing during sliding, reducing sliding noise of the ejection device, and improving the ejection smoothness of the ejection device.

[0052] An embodiment of the present application provides a range-adjustable ejection device, combined with Figure 3 and Figure 6 As shown, a sliding groove 102 is provided on the inner surface of the lower shell, and a protruding slide rail 504 is provided on the ejection rod. The ejection device moves on the sliding groove 102 on the inner surface of the lower shell based on the protruding slide rail 504. By providing the protruding slide rail 504, the contact area between the ejection device and the lower shell is reduced, thereby reducing the influence of the friction generated by the ejection device and the lower shell during the sliding process on the sliding, thereby improving the sliding smoothness of the ejection device.

[0053] In the ejection device with adjustable range provided in the fourteenth embodiment of the present application, Figure 1 and Figure 2 As shown, the outer surfaces of the upper shell 100 and the lower shell 1100 are provided with shock-absorbing pads 400 to reduce the impact of vibration generated by the ejection device during ejection. This embodiment reduces the impact of vibration caused by the ejection device ejecting by providing shock-absorbing pads 400 on the upper shell and the lower shell, thereby optimizing the user experience.
