Abstract
Description
Technical Field
[0001] This utility model relates to transmission mechanisms, and more particularly to a transmission mechanism that can be used for both hand and electric flashlights. Background Technology
[0002] Currently, ventilation fans or louvers are generally directly driven by a motor or manually. However, the single drive mode makes it inconvenient for users, so improvements are needed. Summary of the Invention
[0003] This utility model addresses the shortcomings of existing technologies, such as the single drive mode of ventilation fans or louvers, by providing a new dual-purpose transmission mechanism for both hand and electric use.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] A dual-purpose flashlight transmission mechanism includes a housing and a telescopic component. The housing has an installation space, and the installation space contains a transmission component. The transmission component drives the telescopic component to extend or retract. The mechanism also includes an electric drive component and a manual component. The electric drive component is located within the installation space and cooperates with the transmission component. The manual component is located outside the housing and cooperates with the transmission component. When the electric drive component is working, the manual component disengages from the transmission component.
[0006] By incorporating both electric and manual drive components, this application enables the transmission mechanism to be driven by either a motor or manually, thereby enhancing user convenience.
[0007] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, the transmission component includes a rotating shaft, a first gear, and a second gear. The first gear and the second gear are respectively installed at the lower end and the upper end of the rotating shaft. The telescopic member has a plurality of toothed holes along its length, and the teeth of the first gear engage with the toothed holes.
[0008] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, the electric drive assembly includes a drive motor and a third gear. The drive motor is installed in the installation space, and the third gear is disposed on the drive shaft of the drive motor. The teeth of the third gear mesh with the teeth of the first gear.
[0009] Preferably, in the above-described dual-purpose hand and electric drive mechanism, a mounting base is provided in the installation space, and the drive motor is mounted on the mounting base.
[0010] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, the manual component includes a handle, the lower end of which is provided with a mounting part, and the second gear is disposed on the mounting part. When the handle is pressed, the mounting part disengages from the second gear.
[0011] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, a return spring is provided between the first gear and the second gear.
[0012] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, a stop post is provided near the bottom of the second gear in the installation space, and a stop cover is provided at the upper end of the second gear.
[0013] Preferably, in the above-described dual-purpose hand and flashlight transmission mechanism, the housing is further provided with a mounting post.
[0014] The present invention has the following advantages through the above structural improvements:
[0015] Compared to traditional driving methods, this application allows for both electric and manual driving. The electric drive component enables the transmission mechanism to be driven by a motor, while the manual component allows it to be driven manually. Furthermore, there is no need for a separate disengagement button when switching between manual and electric modes; simply operating the drive shaft is sufficient, thus simplifying user operation. In this application, the two different driving methods effectively enhance user convenience during use. Attached Figure Description

Detailed Implementation
[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the present invention:
[0022] Example 1
[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a dual-purpose flashlight transmission mechanism includes a housing 1 and a telescopic component 2. The housing 1 has an installation space 11, and the installation space 11 has a transmission component 3. The transmission component 3 drives the telescopic component 2 to extend or retract. It also includes an electric drive component 4 and a manual component 5. The electric drive component 4 is located in the installation space 11 and cooperates with the transmission component 3. The manual component 5 is located outside the housing 1 and cooperates with the transmission component 3. When the electric drive component 4 is working, the manual component 5 disengages from the transmission component 3.
[0024] Specifically, the telescopic component 2 is used to connect to the ventilation fan or louvers, so that the electric drive component 4 and the manual component 5 can respectively drive the telescopic component 2 to extend or retract, thereby driving the ventilation fan or louvers to open or close.
[0025] Preferably, the transmission assembly 3 includes a rotating shaft 31, a first gear 32 and a second gear 33. The first gear 32 and the second gear 33 are respectively installed at the lower end and the upper end of the rotating shaft 31. The telescopic member 2 has a plurality of tooth holes 21 along the length direction, and the teeth of the first gear 32 cooperate with the tooth holes 21.
[0026] Specifically, the transmission component 3 can improve the smoothness of the telescopic component 2 when it extends or retracts.
[0027] Preferably, the electric drive assembly 4 includes a drive motor 41 and a third gear 42. The drive motor 41 is installed in the installation space 11, and the third gear 42 is disposed on the drive shaft of the drive motor 41. The teeth of the third gear 42 mesh with the teeth of the first gear 32.
[0028] Specifically, the drive motor 41 is a forward and reverse rotating motor.
[0029] Preferably, the installation space 11 is provided with a mounting base 111, and the drive motor 41 is mounted on the mounting base 111.
[0030] Specifically, in the above structure, when the electric drive component 4 is working, it first drives the motor 41 to drive the third gear 42 to rotate. Then, the third gear 42 drives the second gear 33 to rotate synchronously, so that the second gear 33 drives the first gear 32 to rotate synchronously. In turn, the first gear 32 can drive the telescopic member 2 to extend or retract.
[0031] More specifically, the mounting base 111 facilitates the installation of the drive motor 41 and also improves the stability of the drive motor 41 after installation.
[0032] like Figure 4 As shown, the manual component 5 includes a handle 51, and a mounting part 511 is provided at the lower end of the handle 51. The second gear 33 is disposed on the mounting part 511. When the handle 51 is pressed, the mounting part 511 disengages from the second gear 33.
[0033] Specifically, splines are provided on the outer peripheral wall of the mounting part 511 and the inner peripheral wall of the second gear 33. The second gear 33 and the mounting part 511 are engaged by splines. When the user presses the handle 51, the splines of the mounting part 511 and the splines of the second gear 33 disengage.
[0034] Preferably, a return spring 6 is provided between the first gear 32 and the second gear 33.
[0035] Specifically, when the manual component 5 is not in use, the return spring 6 is in a relaxed state, while in the working state, the return spring 6 is in a tightened state.
[0036] Preferably, the mounting space 11 is provided with a stop post 7 near the bottom of the second gear 33, and the upper end of the second gear 33 is provided with a stop cover 9.
[0037] More specifically, through the cooperation of the stop post 7 and the stop cover 9, on the one hand, when the user presses the handle 51, it can prevent the second gear 33 from falling off, and on the other hand, it can limit the second gear 33 to prevent the second gear 33 from jumping up and down.
[0038] In the above structure, when the manual component 5 is working, the handle 51 is first pressed down to disengage the mounting part 511 from the second gear 33, and the return spring 6 is in a tightened state. Then, the handle 51 is rotated to drive the transmission shaft 31 to rotate the first gear 32. The first gear 32 can then drive the telescopic part 2 to extend or retract. After the operation is completed, the mounting part 511 is reset under the action of the return spring 6, so that the mounting part 511 and the second gear 33 are re-engaged.
[0039] Preferably, the box body 1 is also provided with mounting posts 8.
[0040] Specifically, the mounting column 8 facilitates the installation of the transmission mechanism at the desired location.
[0041] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
