Description

Technical Field

[0001] The present application relates to the technical field of knob switches, and in particular to a gear transmission knob. Background Art

[0002] The rotary switch is a type of regulating switch and is widely used in various fields. For example, in the automotive field, the rotary switch can be used to switch different control states.

[0003] At present, the rotation of the knob switch is mainly achieved by ball bearings. For example, the "rotating structure of the thermostat for realizing rotary temperature adjustment" disclosed in the Chinese patent "CN202321398288.3" is sealed between the touch screen and the fixed frame by multiple steel columns so that the two can rotate relative to each other. Although this method can make the knob switch have a certain degree of rotation adjustment smoothness, its parts cost and assembly cost are relatively high, which is suitable for some markets with strong consumption power. For the mid- and downstream markets, this type of knob switch has poor market competitiveness because it does not have a cost advantage. Utility Model Content

[0004] The purpose of this application is to provide a gear transmission knob to solve at least one of the above technical problems.

[0005] In order to solve the above technical problems, the present application provides a gear transmission knob, including a face shell, a knob, a base and a transmission gear;

[0006] The knob is rotatably disposed between the face shell and the base, and cooperates with the face shell and the base to form an accommodation space, and the transmission gear is rotatably disposed in the accommodation space;

[0007] A plurality of teeth are arranged on the inner wall of the knob in a circumferential direction thereof, and the knob is meshed with the transmission gear through the teeth;

[0008] Wherein, when the knob is rotated, the knob is suitable for driving the transmission gear to rotate through the teeth;

[0009] In the above implementation process, it can be understood that the gear-driven knob provided by this solution belongs to a part of the knob switch. Compared with the structure of the traditional knob switch, the gear-driven knob provided by this solution is provided with a tooth structure on the inner wall of the knob, and a transmission gear meshing with it is further provided. When the user rotates the knob, the knob rotates and drives the transmission gear to rotate during the rotation. When the gear-driven knob provided by this solution is combined with electronic devices to form a knob switch, the rotation of the transmission gear can be used to control the electronic devices, that is, the rotation action of the knob is transmitted to the electronic devices through the transmission gear, and finally the control of the knob switch is realized. The structure of this solution is simple, and compared with the method using a ball structure, the overall manufacturing cost is lower, and the assembly steps are also simpler, providing a more economical choice for the manufacture of knob switches, thus effectively filling the market gap.

[0010] Preferably, a first through hole is provided on the base, and a first step is provided on the inner wall of the first through hole. The transmission gear is adapted to partially extend into the first through hole and one end thereof is adapted to abut against the first step.

[0011] A second through hole is provided on the face shell. A convex column is formed by extending the axis of one end of the transmission gear close to the face shell along its axial direction, and the convex column is adapted to extend into the second through hole.

[0012] In the above implementation process, the upper and lower ends of the transmission gear are respectively limited by the first through hole and the second through hole, that is, the transmission gear can rotate between the first through hole and the second through hole.

[0013] Preferably, a first groove is formed at one end of the transmission gear close to the base, and the first groove communicates with the first through hole. A convex block is provided on one side of the inner wall of the first groove.

[0014] In the above implementation process, a convex block is provided inside the transmission gear. When the transmission gear rotates, the position of the convex block will change. When assembling the complete knob switch with electronic devices subsequently, the position change of the convex block can be used to control the electronic devices.

[0015] Preferably, spherical protrusions are provided at both the end of the tooth structure close to the face shell and the end close to the base; the spherical protrusions are adapted to abut against the face shell and the base.

[0016] In the above implementation process, spherical protrusions are further provided at the upper and lower ends of the tooth structure in this solution, that is, the upper and lower ends of the tooth structure abut against the base and the face shell through the spherical protrusions. In this way, the contact area between the knob and the face shell and the base can be effectively reduced, thereby reducing the relative friction between the knob and the two, so that the user can operate the knob more smoothly and improve the user experience.

[0017] Preferably, an annular groove is provided on the outer periphery of the front shell, and a third through hole is provided on the inner bottom surface of the annular groove;

[0018] It further includes an annular top cover adapted to the annular groove. The annular top cover is provided with a fixing post adapted to the third through hole, and the fixing post is adapted to extend into the annular groove;

[0020] Preferably, a closed-loop partition is provided on the side of the front shell close to the base and on the side of the base close to the front shell. The partition and the knob form a first area, and the transmission gear is arranged in the first area;

[0021] In the above implementation process, the partition on the front shell and the base can separate the transmission gear, so that multiple independent areas can be formed to prevent the transmission gear from being interfered by other components during rotation and affecting normal rotation.

[0022] Preferably, a light-transmitting plate is provided on the front shell;

[0023] In the above implementation process, the light-transmitting plate can achieve light transmission, so that it can cooperate with some LED display modules to display different patterns.

[0024] Preferably, a plurality of protrusions are provided on the outer wall of the knob around the circumference of the knob;

[0025] In the above implementation process, the protrusions formed on the outer wall of the knob can improve the operating feel when the user uses it, thereby improving the user experience. At the same time, it can also increase the relative friction between the hand and the knob to achieve better control.

[0026] Compared with the prior art, the beneficial effects of the present application are as follows: Compared with the structure of the traditional rotary switch, the present solution provides a gear-driven knob with a tooth structure arranged on the inner wall of the knob, and a transmission gear meshing with it is further provided. When the user rotates the knob, the knob rotates and drives the transmission gear to rotate during the rotation process. When the gear-driven knob provided by the present solution is combined with electronic devices to form a rotary switch, the rotation of the transmission gear can be used to control the electronic devices, that is, the rotation action of the knob is conducted to the electronic devices through the transmission gear, and finally the control of the rotary switch is realized; the structure of the present solution is simple, and compared with the method using a ball structure, the overall manufacturing cost is lower, and the assembly steps are also simpler, providing a more economical choice for the manufacture of rotary switches, thereby effectively filling the market gap.

[0040] Embodiment

[0041] At present, the rotation of the knob switch is mainly achieved by balls, such as the "rotation structure of the thermostat for realizing rotation temperature adjustment" disclosed in the Chinese patent "CN202321398288.3", which is sealed between the touch screen and the fixed frame by multiple steel columns so that the two can rotate relative to each other. Although this method can make the knob switch have a certain degree of rotation adjustment smoothness, its parts cost and assembly cost are relatively high, which is suitable for some markets with strong consumption power. For the mid- and downstream markets, this type of knob switch has poor market competitiveness because it does not have cost advantages. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0042] Specifically, this embodiment provides a gear transmission knob, see Figure 1-7 , including a housing 10, a knob 20, a base 30 and a transmission gear 40;

[0043] Specifically, the knob 20 is rotatably disposed between the housing 10 and the base 30, and cooperates with the housing 10 and the base 30 to form an accommodation space, and the transmission gear 40 is rotatably disposed in the accommodation space;

[0044] Furthermore, a plurality of teeth 21 are provided around the inner wall of the knob 20 in a circumferential direction, and the knob 20 is meshed with the transmission gear 40 through the teeth 21;

[0045] When the knob 20 rotates, the knob 20 is adapted to drive the transmission gear 40 to rotate through the teeth 21;

[0046] In the above scheme, it can be understood that the gear transmission knob 20 provided in the present scheme is a partial structure of the knob 20 switch; compared with the structure of the traditional knob 20 switch, the present scheme provides a gear transmission knob 20 with a tooth 21 structure set on the inner wall of the knob 20, and further sets a transmission gear 40 meshing therewith. When the user rotates the knob 20, the knob 20 rotates and drives the transmission gear 40 to rotate during the rotation. When the gear transmission knob 20 provided in the present scheme is combined with an electronic device to form a knob 20 switch, the purpose of controlling the electronic device can be achieved by rotating the transmission gear 40, that is, the rotation action of the knob 20 is transmitted to the electronic device through the transmission gear 40, and finally the control of the knob 20 switch is realized; the present scheme has a simple structure, and compared with the method of using a ball structure, the overall cost is lower and the assembly steps are simpler, which provides a more economical option for the manufacture of the knob 20 switch, thereby effectively filling the market gap.

[0047] For details, see Figure 2-3 A first through hole is provided on the base 30, and a first step 311 is provided on the inner wall of the first through hole. The transmission gear 40 is adapted to partially extend into the first through hole and one end thereof is adapted to abut against the first step 311;

[0048] Further, a second through hole 11 is provided on the front shell 10. A convex column 41 is formed by extending the axis of the end of the transmission gear 40 close to the front shell 10 along its axial direction. The convex column 41 is adapted to extend into the second through hole 11.

[0049] In the above solution, the upper and lower ends of the transmission gear 40 are respectively limited by the first through hole and the second through hole 11, that is, the transmission gear 40 can rotate between the first through hole and the second through hole 11.

[0050] Specifically, please refer to Figure 4 , a first groove 42 is formed at the end of the transmission gear 40 close to the base 30. The first groove 42 communicates with the first through hole. A convex block 421 is provided on one side of the inner wall of the first groove 42.

[0051] In the above solution, a convex block 421 is provided inside the transmission gear 40. When the transmission gear 40 rotates, the position of the convex block 421 will change. When it is subsequently assembled with electronic devices into a complete knob 20 switch, the position change of the convex block 421 can be used to control the electronic devices.

[0052] Specifically, spherical protrusions 211 are provided at both the end of the tooth 21 close to the front shell 10 and the end close to the base 30; the spherical protrusions 211 are adapted to abut against the front shell 10 and the base 30.

[0053] In the above solution, spherical protrusions 211 are further provided at the upper and lower ends of the tooth 21, that is, the upper and lower ends of the tooth 21 abut against the base 30 and the front shell 10 through the spherical protrusions 211. In this way, the contact area between the knob 20 and the front shell 10 and the base 30 can be effectively reduced, and further the relative friction between the knob 20 and the two can be reduced, so that the user can operate the knob 20 more smoothly and improve the user experience.

[0054] Specifically, an annular groove 12 is provided on the outer periphery of the front shell 10, and a third through hole 121 is provided on the inner bottom surface of the annular groove 12.

[0055] Further, please refer to Figure 7 , it further includes an annular top cover 50 adapted to the annular groove 12. The annular top cover 50 is provided with a fixing column 51 adapted to the third through hole 121. The fixing column 51 is adapted to extend into the annular groove 12.

[0056] In the above solution, the top cover is further provided in this solution to cover the gap between the knob 20 and the front shell 10, thereby improving the aesthetics of the entire knob 20; and the connection method between the top cover and the front shell 10 is the connection of the fixing column 51 and the through hole, with a simple structure and quick and easy assembly; it can be understood that it can be further combined stably with glue.

[0057] Specifically, please refer to Figure 2-3 , on one side of the front shell 10 close to the base 30 and on one side of the base 30 close to the front shell 10, there is a closed-loop partition 13. The partition 13 and the knob 20 form a first area, and the transmission gear 40 is arranged in the first area;

[0058] In the above solution, the partition 13 on the front shell 10 and the base 30 can separate the transmission gear 40, so that multiple independent areas can be formed, avoiding the interference of other components on the normal rotation of the transmission gear 40 during rotation.

[0059] Specifically, a light-transmitting plate 14 is provided on the front shell 10;

[0060] In the above solution, the light-transmitting plate 14 can achieve light transmission, so that it can cooperate with some LED display modules to display different patterns.

[0061] Specifically, a plurality of protrusions 22 are circumferentially arranged around the outer wall of the knob 20 along the circumference of the knob 20;

[0062] In the above solution, the protrusions 22 formed on the outer wall of the knob 20 can improve the operating feel when the user uses it, thereby improving the user experience. At the same time, it can also increase the relative friction between the hand and the knob 20 to achieve better control.

[0063] The above description is only a preferred embodiment of the present application, and does not impose any form of limitation on the present application. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application all belong to the scope of the technical solution of the present application.
