[0001] This application relates to the technical field of automotive power switches, and in particular, to a high-sealing automotive main power switch. Background Art

[0002] The main function of the automotive main power switch is to control the power output of the automotive battery, thereby controlling the on / off of the entire vehicle's circuit system. Usually, the automotive main power switch is a rotary switch, which includes a base, a rotating shaft, and a rotary key. Both the rotating shaft and the rotary key are connected to the base. The rotating shaft is rotatably installed on the base, and the rotary key is provided at the top of the rotating shaft for the user to operate to rotate the rotating shaft. After the rotating shaft rotates, it can drive the on / off of the connection between the base and the battery circuit.

[0003] However, with the rotation of the rotating shaft, it will cause certain wear on the base, and then form a gap, resulting in poor sealing at the rotating shaft. Some rainwater or water remaining after car washing is likely to seep into the interior of the base along the outer wall of the rotating shaft from the gap at the rotating shaft, and in severe cases, it is likely to cause a short circuit in the automotive power circuit. Utility Model Content

[0004] In order to improve the sealing performance at the rotating shaft of the automotive power switch, this application provides a high-sealing automotive main power switch.

[0005] A high-sealing automotive main power switch provided by this application adopts the following technical solutions:

[0006] A high-sealing automotive main power switch includes a switch housing, a rotating shaft installed inside the switch housing, and a rotary key for driving the rotation of the rotating shaft. An insertion hole for inserting the rotating shaft is provided inside the switch housing. A sealing ring is sleeved on the rotating shaft, and the outer peripheral wall of the sealing ring abuts against the hole wall of the insertion hole. A partition ring groove is provided on the outer peripheral wall of the sealing ring, and the outer peripheral wall of the sealing ring is divided into two sections by the partition ring groove.

[0007] Preferably, a shaft sealing ring groove for sleeving the sealing ring is provided on the rotating shaft.

[0008] Preferably, the partition ring groove is also provided on the inner peripheral wall of the sealing ring, and the inner peripheral wall of the sealing ring is divided into two sections by the partition ring groove located on the inner peripheral wall of the sealing ring.

[0009] Preferably, the cross-section of the sealing ring is X-shaped.

[0010] Preferably, the switch housing includes a switch lower shell and a switch upper shell. An installation lower groove is provided at the top of the switch lower shell, and a circuit on / off component is installed in the installation lower groove. The switch upper shell is used to cover the installation lower groove.

[0011] Preferably, an upper mounting groove communicating with the lower mounting groove is formed at the bottom of the upper switch housing, and a part of the circuit opening and closing assembly is located in the lower mounting groove and a part thereof is located in the upper mounting groove.

[0012] Preferably, an annular sealing groove is formed at the notch of the upper mounting groove, an assembly sealing ring is arranged in the annular sealing groove, and both the lower mounting groove and the upper mounting groove are located inside the assembly sealing ring.

[0013] Preferably, a plurality of threaded ring columns are circumferentially and spacedly arranged at the bottom of the upper switch housing, a butt joint hole for inserting the threaded ring columns is formed at the top of the lower switch housing, the number of the butt joint holes is the same as and corresponds to the number of the threaded ring columns one by one, and screws threadedly mounted on the threaded ring columns are inserted into the butt joint holes. All the threaded ring columns are located outside the assembly sealing ring.

[0014] Preferably, lubricating oil is smeared on the sealing ring.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The sealing ring can seal between the rotating shaft and the switch housing, making it difficult for water to penetrate into the interior of the switch housing. In addition, the arrangement of the partition ring groove divides both the inner peripheral wall and the outer peripheral wall of the sealing ring into two sections, thereby forming a double sealing effect and further improving the sealing performance at the rotating shaft.

[0017] 2. The sealing ring is coated with lubricating oil before installation, making the rotation of the rotating shaft smoother. In addition, the excess lubricating oil can be stored in the partition groove, and it is not easy to cause waste of lubricating oil.

[0018] 3. Since a circuit opening and closing assembly also needs to be installed inside the switch housing, splitting the switch housing into an upper switch housing and a lower switch housing makes the installation of the circuit opening and closing assembly more convenient. At the same time, the arrangement of the assembly sealing ring seals the connection between the upper switch housing and the lower switch housing, and it is not easy for water to penetrate from between the upper switch housing and the lower switch housing into the lower mounting groove or the upper mounting groove to cause a short circuit to the circuit opening and closing assembly.

[0019] 4. Compared with arranging the assembly sealing ring outside the threaded ring column, arranging the assembly sealing ring inside the threaded ring column can make the size of the assembly sealing ring smaller, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following further Figures 1-6 describes the present application in detail with reference to the

[0028] An embodiment of the present application discloses a high-sealing automotive power main switch. Referring to Figure 1 and Figure 2 , the high-sealing automotive power main switch includes a switch housing 1, a rotating shaft 2, and a knob key 3. A conductive column 4 for connecting with a cable on an automotive power source is installed on one side of the switch housing 1. An internal circuit disconnection and connection component capable of contacting or disconnecting from the conductive column 4 to achieve circuit disconnection or energization is installed inside the switch housing 1. The rotating shaft 2 is rotatably installed inside the switch housing 1 for controlling the circuit disconnection and connection component to contact or disconnect from the conductive column 4. The rotary key is located on the side of the switch housing 1 away from the conductive column 4, and the rotary key can drive the rotating shaft 2 to rotate, thereby achieving circuit disconnection and connection. A sealing ring 21 is sleeved on the rotating shaft 2, and the sealing ring 21 can seal between the rotating shaft 2 and the switch housing 1, so that water or dust is not easily introduced into the inside of the switch housing 1 to affect the circuit disconnection and connection component.

[0029] Referring to Figure 1 and Figure 2, the switch housing 1 includes a switch lower housing 11 and a switch upper housing 12. An installation lower groove 13 is provided at the top of the switch lower housing 11 (i.e., the side of the switch lower housing 11 close to the switch upper housing 12), and the switch upper housing 12 is used to cover the installation lower groove 13. An installation upper groove 14 communicating with the installation lower groove 13 is provided at the bottom of the switch upper housing 12 (i.e., the side of the switch upper housing 12 close to the switch lower housing 11), and part of the circuit break-off component is located in the installation lower groove 13 and part is located in the installation upper groove 14.

[0030] Referring to Figure 3 and Figure 4 , a jack 15 is provided at the bottom of the installation upper groove 14. The jack 15 penetrates through the switch upper housing 12, and the size of the jack 15 is smaller than that of the installation upper groove 14. The rotating shaft 2 is inserted into the jack 15 and rotates within the jack 15. The side of the rotating shaft 2 close to the switch lower housing 11 will cooperate with the circuit break-off component to drive the circuit break-off component to lift so as to contact or disconnect from the conductive column 4.

[0031] A rotating shaft sealing ring groove 22 for sleeving the sealing ring 21 is provided on the rotating shaft 2. The outer peripheral wall of the sealing ring 21 abuts against the inner wall of the jack 15, thereby playing a role in sealing the rotating shaft 2.

[0032] Referring to Figure 3 and Figure 4 , dividing ring grooves 23 are provided on the outer peripheral wall, inner peripheral wall, upper peripheral wall and lower peripheral wall of the sealing ring 21, that is, the cross section of the sealing ring 21 is X-shaped. The outer peripheral wall of the sealing ring 21 is divided into two spaced sections by the dividing groove on the outer peripheral wall. Similarly, the inner peripheral wall, upper peripheral wall and lower peripheral wall of the sealing ring 21 are each formed into two spaced sections through the corresponding dividing grooves, thereby enabling the sealing ring 21 to form a double seal and further improving the sealing effect of the sealing ring 21.

[0033] Lubricating oil is evenly applied to the sealing ring 21 before installation, so that the rotating shaft 2 rotates smoothly during the rotation process. In addition, the excess lubricating oil can flow into the corresponding dividing grooves and be stored.

[0034] After the rotating shaft 2 is inserted into the jack 15, it will not protrude from the jack 15. A keyway hole 24 is provided on the side of the rotating shaft 2 away from the switch lower housing 11. A pin shaft 31 integrally formed on one side of the rotary key is inserted into the jack 15, and a convex key 32 inserted into the keyway hole 24 is provided on the pin shaft 31, thereby enabling the rotary key to drive the rotating shaft 2 to rotate.

[0035] Referring to Figure 5 and Figure 6, a threaded ring column 16 is integrally formed on one side of the switch upper shell 12 where the upper groove 14 is provided, and a plurality of threaded ring columns 16 are provided, and the plurality of threaded ring columns 16 are arranged at intervals around the upper groove 14. A docking hole 17 for inserting the threaded ring column 16 is provided on one side of the switch lower shell 11 where the lower groove 13 is provided, and the docking hole 17 penetrates the switch lower shell 11 along its own opening direction, and a screw is inserted into the docking hole 17, and the screw is threadedly installed in the threaded ring column 16, thereby fixing the switch upper shell 12 and the switch lower shell 11 together. Since a plurality of threaded ring columns 16 are provided, a plurality of docking holes 17 are also provided, and the number of docking holes 17 is consistent with the number of threaded ring columns 16 and corresponds one to one; similarly, a screw is inserted into each docking hole 17.

[0036] Reference Figure 5 and Figure 6 An annular sealing groove 18 is provided on one side of the upper shell where the threaded ring column 16 is provided. The groove diameter of the upper groove 14 is smaller than the inner diameter of the annular sealing groove 18, that is, the upper groove 14 is located inside the annular sealing groove 18. The groove diameter of the lower groove 13 is also smaller than the inner diameter of the annular sealing groove 18, that is, the lower groove 13 is located inside the annular sealing groove 18. An assembly sealing ring 19 is installed in the annular sealing groove 18, and the side of the assembly sealing ring 19 that is away from the bottom of the annular sealing groove 18 protrudes from the annular sealing groove 18, and then when the switch upper shell 12 and the switch lower shell 11 are fixed together, the assembly sealing ring 19 can play a sealing role, so that dust or water is not easy to enter the upper groove 14 and the lower groove 13.

[0037] Reference Figure 5 and Figure 6 In order to facilitate the deformation of the assembly sealing ring 19 after being squeezed, a deformation arc surface is provided on one side of the assembly sealing ring 19 close to the bottom of the annular sealing groove 18. Under normal conditions, the top of the arc of the deformation arc surface abuts against the bottom of the annular sealing groove 18; the rest of the deformation arc surface will not abut against the bottom of the annular sealing groove 18. In addition, the plurality of threaded ring columns 16 are all located outside the annular sealing groove 18, so that the size of the assembly sealing ring 19 can be smaller, thereby reducing the production cost.

[0038] The implementation principle of the highly sealed main power switch for automobiles in the embodiment of the present application is as follows: the cross section of the sealing ring 21 is X-shaped through multiple separation grooves, so that the sealing ring 21 forms a double sealing effect on the rotating shaft 2, so that dust or water is not easy to penetrate into the interior of the switch housing 1 from the rotating shaft 2 to affect the circuit disconnection component. In addition, the sealing ring 21 will be fully coated with lubricating oil before installation, so that the rotating shaft 2 can rotate more smoothly, and the corresponding lubricating oil will automatically flow into the corresponding separation groove and be stored.

[0039] The setting of the assembled sealing ring 19 seals the connection between the upper switch housing 12 and the lower switch housing 11, and water is not likely to seep between the upper switch housing 12 and the lower switch housing 11 into the lower installation groove 13 or the upper installation groove 14 to cause a short circuit to the circuit opening and closing component.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
