Description

Technical Field

[0001] The present invention relates to the technical field of switches, and particularly to a gear structure and a dimming and speed control switch. Background Art

[0002] Dimming and speed control switches are often seen in our daily life, which can be used to adjust the illumination brightness and also the rotation speed.

[0003] The gear shifting mechanism of the dimming and speed control switch mainly includes a push button assembly, a moving contact, and multiple groups of static contact assemblies. The push button assembly is movably installed on the housing, the moving contact is fixedly installed on the push button assembly, and multiple groups of static contact assemblies are arranged at intervals along the moving direction of the push button assembly. The user drives the push button assembly to move, thereby driving the moving contact to contact different static contact assemblies to achieve the switching of different gears. Currently, there is a situation where the gear positioning of the dimming and speed control switch is inaccurate, that is, the push button assembly can be driven under a small external force, thus prone to misoperation and affecting the user experience. In addition, since the moving contact moves translationally with the push button assembly, in order to ensure that the moving contact does not contact and connect with the subsequent static contact assembly before being completely separated from the previous static contact assembly, a relatively large distance must be maintained between adjacent two static contact assemblies. Therefore, when there are many groups of static contact assemblies, the volume of the switch will be relatively large. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of inaccurate gears in the prior art, and thus provide a gear structure with accurate gears and a dimming and speed control switch having this gear structure.

[0005] To this end, the present invention provides a gear structure, including a plurality of positioning grooves and a gear shifting component. The plurality of positioning grooves are sequentially arranged at intervals on the housing; the gear shifting component is movably installed on the housing, and includes a positioning member and a biasing member connected to the positioning member. The positioning member has a first position for positioning and cooperating with the positioning groove and a second position separated from the positioning groove, and the biasing member applies a biasing force to the positioning member to move it in the direction of the first position.

[0006] The positioning member is a roller. In the first position, part of the roller can extend into the positioning groove.

[0007] A bevel surface or an arc surface that can contact the roller is provided at the first opening of the positioning groove.

[0008] The gear shifting component includes a roller and a mounting seat. The roller is provided with a connecting shaft in the middle; the mounting seat has two oppositely arranged mounting plates at the bottom for the roller to be installed between them, and a first long hole for the connecting shaft to extend out and restricting the moving track of the connecting shaft is provided on the mounting plate.

[0009] The first long slot is provided with a second opening, and the diameter of the second opening is smaller than the diameter of the connecting shaft.

[0010] The housing is provided with multiple groups of static contact assemblies arranged at intervals along the moving direction of the gear position switching assembly. Each group of static contact assemblies includes two static contacts respectively arranged on both sides of the moving direction of the gear position switching assembly. The connecting shaft is a metal shaft; in the first position, both ends of the connecting shaft are in contact and communication with the corresponding static contacts.

[0011] The biasing member includes a spring piece main body and two elastic arms. The spring piece main body is fixed on the mounting seat; the two elastic arms are respectively arranged on both sides of the spring piece main body and are bent and connected to it. The two elastic arms respectively abut against both ends of the connecting shaft correspondingly.

[0012] The gear position switching assembly further includes a push button arranged on the mounting seat and capable of being linked with it. The push button is slidably connected to the housing through a slide rail structure. The slide rail structure includes a chute arranged on the inner side surface of the housing and at least one slider arranged on one side of the push button and capable of being slidably connected to the chute.

[0013] The push button is hooked and connected to the housing through an elastic hook structure. The elastic hook structure includes a second long slot and at least one elastic hook. The second long slot is arranged on the top surface of the housing, and the extending direction of the second long slot is parallel to the moving direction of the push button; at least one elastic hook is arranged on the other side of the push button. After the elastic hook passes through the second long slot, it can be hooked and connected to the housing.

[0014] The present invention also provides a dimming and speed regulating switch, including the gear position structure as described above.

[0015] The technical solution of the present invention has the following advantages:

[0016] 1. The gear position structure provided by the present invention includes multiple positioning grooves and a gear position switching assembly. The multiple positioning grooves are arranged on the housing at intervals in sequence; the gear position switching assembly is movably installed on the housing and includes a positioning member and a biasing member connected to the positioning member. The positioning member has a first position for positioning and cooperating with the positioning groove and a second position separated from the positioning groove. The biasing member applies a biasing force to the positioning member to make it move towards the first position. The above gear position structure can ensure accurate gear position positioning during the operation of the dimming and speed regulating switch, is not prone to misoperation, is convenient for users to use, and the mutually cooperating positioning groove and positioning member have the advantage of simple structure.

[0017] 2. In the gear position structure provided by the present invention, the positioning member is a roller. Among them, in the first position, part of the roller can extend into the positioning groove, and the roller can reduce the wear between it and the positioning groove and extend the service life.

[0018] 3. For the gear position structure provided by the present invention, a bevel surface or an arc surface that can contact the roller is provided at the first opening of the positioning groove. The bevel surface increases the caliber of the opening of the positioning groove, and the step where the bevel surface is located can better limit and block the roller.

[0019] 4. For the gear position structure provided by the present invention, the first long hole is provided with a second opening, and the caliber of the second opening is smaller than the diameter of the connecting shaft, which can prevent the connecting shaft from detaching from the mounting plate, resulting in the mounting plate being unable to drive the connecting shaft to move for gear shifting.

[0020] 5. For the gear position structure provided by the present invention, a plurality of groups of static contact assemblies are provided on the housing at intervals along the moving direction of the gear position switching assembly. Each group of static contact assemblies includes two static contacts respectively arranged on both sides of the moving direction of the gear position switching assembly. The connecting shaft is a metal shaft; in the first position, both ends of the connecting shaft are in contact and communication with the corresponding static contacts. On the one hand, the connecting shaft is used as a connecting piece between the roller and the mounting seat. On the other hand, the connecting shaft is used as a "moving contact" and can connect the two static contacts in contact and communication, that is, one connecting shaft can meet two usage functions, so that there are fewer parts and a simple structure, reducing the production cost; in addition, during gear shifting, since the connecting shaft can move obliquely upward relative to the static contacts following the roller, when the connecting shaft separates from the previous static contact assembly, part or all of the connecting shaft is still above the previous static contact assembly. Compared with the prior art where the moving contact follows the push button to translate and the moving contact needs to move completely between the two static contact assemblies to separate from the previous static contact assembly, in the solution of the present application, the distance between adjacent two static contact assemblies can be set smaller, and the switch can be designed to be more miniaturized.

[0021] 6. For the gear position structure provided by the present invention, the gear position switching assembly further includes a push button provided on the mounting seat and capable of being linked with it. The push button is slidably connected to the housing through a slide rail structure. The slide rail structure includes a chute provided on the inner side surface of the housing and at least one slider provided on one side of the push button and capable of slidingly connecting with the chute. The slide rail structure can greatly reduce the friction between the push button and the housing during the operation of the dimming and speed regulating switch, and the mutually cooperating chute and slider have the advantage of simple structure.

[0022] 7. For the gear position structure provided by the present invention, the push button is hooked and connected to the housing through an elastic hook structure. The elastic hook structure includes a second long hole and at least one elastic hook. The second long hole is provided on the top surface of the housing, and the extending direction of the second long hole is parallel to the moving direction of the push button; at least one elastic hook is provided on the other side of the push button. After the elastic hook passes through the second long hole, it can be hooked and connected to the housing. The elastic hook structure can make the connection between the push button and the housing more firm and prevent the push button from detaching. Description of the Drawings
