[0038] Please refer to Figures 1 to 9 .

[0039] The combined switch for automobile provided by the embodiment of the utility model comprises a shell 10, a PCBA 20, a handle 30 and a magnet support 40, the PCBA 20 is arranged in the shell 10, a Hall sensor 21 is arranged below the PCBA 20, the handle 30 is hinged to the shell 10 through an up and down gear rotating shaft 31, that is, the handle 30 can swing up and down relative to the shell 10, one end of the handle 30 is a control end, and the other end is a driving end 32, the control end is used for being controlled by a driver, and the driving end 32 extends into the shell 10, wherein, for example, Figure 1And Figure 2 As shown in the drawings, the driving end 32 is provided with a driving groove 33, the magnet bracket 40 is hinged in the shell 10 through the driven shaft 43 and is located below the PCBA 20, the upper end of the magnet bracket 40 is provided with a magnet 41, the magnet bracket 40 is provided with a driving shaft 42, the driving shaft 42 is arranged in parallel with the driven shaft 43 and the up-down gear shift shaft 31, one end of the driving shaft 42 is located in the driving groove 33, when the handle 30 rotates around the up-down gear shift shaft 31, the driving shaft 42 can be pushed through the driving groove 33, and then the magnet bracket 40 is driven to swing around the driven shaft 43, so as to change the left-right position of the magnet 41 relative to the Hall sensor 21. If the magnet bracket 40 rotates around the up-down gear shift shaft 31 of the handle 30, the magnet 41 cannot be arranged below the PCBA 20. In the automobile combination switch provided by the utility model, since the magnet bracket 40 swings around the driven shaft 43 instead of rotating around the up-down gear shift shaft 31 of the handle 30, the magnet 41 can be arranged below the PCBA 20. Therefore, by arranging the driving groove 33 on the driving end 32 of the handle 30 and arranging the driving shaft 42 of the magnet bracket 40 in a matched mode, the size of the automobile combination switch in the horizontal projection can be effectively reduced, so that the arrangement requirement of a small space can be met, and the area of the PCBA 20 can be appropriately increased, that is, the area of the PCBA 20 for arranging electronic devices can be increased.

[0040] In some embodiments, as Figure 3 As shown in the drawings, the shell 10 is provided with a front-rear swing bracket 50, the front-rear swing bracket 50 is hinged in the shell 10 through a front-rear gear shift shaft, the up-down gear shift shaft 31 is hinged to the front-rear swing bracket 50, that is, the front-rear swing bracket 50 can swing forward and backward relative to the shell 10, and the handle 30 can swing up and down relative to the front-rear swing bracket 50. The driven shaft 43 is hinged to the front-rear swing bracket 50, and since the magnet bracket 40 is hinged to the driven shaft 43, the magnet bracket 40 can swing relative to the front-rear swing bracket 50. When the handle 30 rotates around the front-rear gear shift shaft, the handle 30, the up-down gear shift shaft 31, the front-rear swing bracket 50, the driven shaft 43 and the magnet bracket 40 are integrated and do not move relative to each other, so that the handle 30 can drive the magnet bracket 40 to swing forward and backward through the front-rear swing bracket 50, so as to change the front-rear position of the magnet 41 relative to the Hall sensor 21. That is, the left-right swing of the magnet 41 can be realized through the up-down gear shift shaft 31, and the front-rear swing of the magnet 41 can be realized through the front-rear gear shift shaft, so that different functions can be realized when the handle 30 is correspondingly rotated, for example, the steering gear shift function can be realized when the handle 30 is operated forward and backward, and the light gear shift function can be realized when the handle 30 is operated up and down.

[0041] In some embodiments, as Figure 2As shown, the front and rear swing bracket 50 is provided with a chamber 51 for the driving end 32 to extend into, and the front and rear swing bracket 50 is provided with an avoiding groove 52 for the upper end of the magnet bracket 40 to extend out of, one end of the driven shaft 43 is connected to the side wall in the chamber 51, and the other end is connected to the magnet bracket 40, one end of the driving shaft 42 is connected to the magnet bracket 40, and the other end is located in the driving groove 33, and the part of the magnet bracket 40 located in the chamber 51 is located between the driving end 32 and the side wall of the chamber 51. When the driving end 32 of the handle 30 drives the driving shaft 42 through the driving groove 33, the magnet bracket 40 can swing around the driven shaft 43, thereby realizing the left and right swinging of the magnet 41. Among them, the driving groove 33 is a waist-shaped groove, one end of the driving shaft 42 is located in the waist-shaped groove, and the waist-shaped groove is used to drive the driving shaft 42 through the plane side wall, when the driving end 32 of the handle 30 rotates, the waist-shaped groove will also rotate, thereby driving the driving shaft 42 to move and rotate relative to the waist-shaped groove under the action of the plane side, thereby realizing the passive swinging of the magnet bracket 40.

[0042] In some embodiments, the magnet bracket 40 comprises a bracket body, a first extension end and a second extension end, wherein the first extension end and the second extension end are integrally formed on the bracket body, the bracket body is hinged to the front and rear swing bracket 50 through the driven shaft 43, the driving shaft 42 is arranged on the first extension end, and the magnet 41 is arranged on the second extension end, wherein the bracket body, the first extension end and the second extension end are in V-shaped structure, which can effectively reduce the consumption materials. Among them, the first extension end is located in the chamber 51 of the front and rear swing bracket 50, and the second extension end is located outside the chamber 51 of the front and rear swing bracket 50.

By unifying the positioning of the SRC / SAS shell 11, the upper shell 12 and the lower shell 13 and the PCBA 20, and using the unified positioning pin 14 for positioning, the number of size chains and the tolerance accumulation between the assembly positioning references of each part can be reduced, thereby improving the sensing position accuracy of the Hall sensor 21 and stabilizing the system function. Among them, the cross section of the positioning pin 14 is preferably cross-shaped, and further, the lower end of the positioning pin 14 is provided with a guide inclined surface 141 to facilitate assembly.

[0044] In some embodiments, asFigure 5 As shown, a plurality of sets of coaxial positioning holes 15 are arranged on the upper shell 12, the lower shell 13 and the PCBA 20 respectively, and a plurality of sets of positioning pins 14 that are matched with the positioning holes 15 are arranged at the lower end of the SRC / SAS shell 11, for example, two sets, three sets or more sets of positioning pins 14 can be used for positioning, and the assembly stability can be improved through the plurality of sets of positioning pins 14.

In the prior art, the sun gear mounting portion 1121 and the planet gear mounting portion 1122 are arranged on the upper and lower sides of the SAS shell 111 respectively, and this arrangement is easy to cause the rotating bearing surfaces of the sun gear 60 and the planet gear 70 to be formed on the upper and lower sides of the mold respectively, and the center distance tolerance accumulates the machining tolerance of each side of the mold and the clamping tolerance of the upper and lower sides of the mold, and the parallelism tolerance between the upper and lower support surfaces is also large, which is easy to cause gear meshing noise and reduce the rotation accuracy. The technical solution provided by the present application can effectively improve the assembly accuracy of the sun gear 60 and the planet gear 70, and further improve the rotation accuracy and reduce the noise.
