[0037] In order to further understand the content of the present invention, the present invention is described in detail with reference to the embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] Seen in Figure 1-2 This embodiment provides an electrode shift mechanism, which includes a rotating shaft 110 and a shift knob 120. The rotating shaft 110 includes a core shaft 111. A negative power electrode sheet 213 and three positive power electrode sheets 214 are circumferentially provided on the side wall of the core shaft 111. A mounting seat 2111 is formed at one axial end of the core shaft 111. The shift knob 120 is rotatably disposed on the mounting seat 2111. A shift spring 221 is provided inside the shift knob 120.

[0040] Seen in Figure 3 .1 and Figure 3 .2. A selection hole 322 is provided on the side of the shift knob 120 close to the positive electrode sheet 214 of the power supply. The selection hole 322 is used to cooperate with the three positive electrode sheets 214 of the power supply. Four first matching holes 323 are provided on the side of the shift knob 120 away from the positive electrode sheet 214 of the power supply.

[0041] According to the solution provided in this embodiment, three power positive plates L1, L2, L3 and one power negative plate N can form three different circuits, which can be switched to different circuits by cooperating with different power positive electrode plates 214 through the selection hole 322 at the shift knob 120.

[0042] Among them, by cooperating with the mounting seat 2111 and the shift knob 120, the overall installation of the rotating shaft 110 and the shift knob 120 can be better realized, and by arranging the shift knob 120 at the mounting seat 2111, the coaxiality of the shift knob 120 and the rotating shaft 110 when they are matched can be improved, thereby better improving the shifting accuracy of the shift knob 120.

[0043] It is understandable that the shift spring 221 is disposed in the shift knob by insert injection molding.

[0044] Seen in Figure 1-4 The mounting seat 2111 includes a plurality of limit buckles 4112 arranged along the circumference of the core shaft 111. The end of the limit buckle 4112 is inclined toward the shift knob 120. A mounting hole 324 is correspondingly formed at the shift knob 120. The limit buckle 4112 is used to cooperate with the mounting hole 324.

[0045] That is, when in use, the mounting hole 324 of the shift knob 120 is aligned with the limiting buckle 4112 and pressed, so that the limiting buckle 4112 limits the shift knob 120 at the mounting seat 2111, thereby better achieving the installation of the shift knob 120.

[0046] Seen in Figure 1-2 The rotating shaft 110 also includes a rotating shaft shell 112, which is sleeved on the outer wall of the core shaft 111. The side wall of the rotating shaft shell 112 is formed with four mounting grooves 1121 that penetrate through. The four mounting grooves 1121 are used to fix with the one negative power electrode sheet 213 and the three positive power electrode sheets 214.

[0047] Specifically, the mounting groove 1121 can limit the position of one negative power electrode sheet 213 and three positive power electrode sheets 214 , thereby facilitating their cooperation with the four-wire track.

[0048] Seen in Figure 1-6 The shaft housing 112 includes a first housing 2121 and a second housing 2122 that can be detachably matched. At least two matching pins 5123 are formed on the side of the first housing 2121 close to the second housing 2122, and at least two second matching holes 6124 are correspondingly formed on the second housing 2122. The matching pins 5123 and the second matching holes 6124 are interference fit.

[0049] Specifically, the matching pin 5123 and the second matching hole 6124 can realize the detachable matching of the first shell 2121 and the second shell 2122, thereby facilitating the installation of one negative power electrode sheet 213 and three positive power electrode sheets 214.

[0050] Seen in Figure 7 The positive electrode sheet 214 of the power supply extends spirally toward the shift knob 120 at one end close to the mounting seat 2111 to form a contact claw 7141 , and the end of the contact claw 7141 is close to the side of the shift knob 120 to form a first contact point 7142 .

[0051] Specifically, the spiral contact claw 7141 can better prevent the shift knob 120 from reversing, thereby avoiding an erroneous switching circuit. The first contact point 7142 is used to cooperate with the shift spring 221, and the shift spring 221 is used to output a positive pole.

[0052] Seen in Figure 8 The negative electrode sheet 213 of the power supply is close to one end of the mounting seat 2111 and extends radially out of the rotating shaft 110 to form a contact portion 8131 .

[0053] Specifically, the contact portion 8131 is used to output the negative electrode.

[0054] Example 2

[0055] Seen in Figure 9-12 This embodiment provides a four-wire track power driver, which includes a driver housing 930, an electrode shift mechanism rotatably disposed in the driver housing 930, and also includes a PCB circuit board fixedly disposed in the driver housing 930. A positive electrode connecting piece 115 and a negative electrode connecting piece 116 are spaced apart on one side of the rotating shaft 110. The positive electrode connecting piece 115 abuts against the side of the shift knob 120 away from the positive electrode piece 214 of the power supply, and the negative electrode connecting piece 116 abuts against the negative electrode piece 213 of the power supply. The positive electrode connecting piece 115 and the negative electrode connecting piece 116 are both electrically connected to the PCB circuit board, and a wire hole 1033 is formed in the driver housing 930.

[0056] It can be understood that the positive connecting piece 115 and the negative connecting piece 116 are used to supply power to the PCB circuit board, so that the PCB circuit board works, and the wire hole 1033 is used to install lamps or other electrical appliances. The lamps or other electrical appliances are electrically connected to the PCB circuit board, and their operation is controlled by the PCB circuit board.

[0057] Among them, a shaft lever 1115 is formed radially on the outer wall of the shaft 110, and a matching groove 931 is formed correspondingly at the driver housing 930. The matching groove 931 is used to cooperate with the shaft lever 1115. Telescopic grooves 932 are formed on both sides of the driver housing 930. The telescopic grooves 932 are used to extend or retract the one negative power electrode plate 213 and the three positive power electrode plates 214 into the driver housing 930 when the electrode shift mechanism rotates.

[0058] Through the above structure, it is better to manually extend or retract one power negative electrode plate 213 and three power positive electrode plates 214 into the driver housing 930, thereby facilitating the installation of the four-wire track power driver on the four-wire guide rail.

[0059] Seen in Figure 9-11 The driver housing 930 includes a third housing 117 and a fourth housing 118 that are detachably matched. A plurality of matching buckles 1171 are formed on one side of the third housing 117, and a plurality of matching slots 1181 are correspondingly formed on the fourth housing 118. The plurality of matching buckles 1171 are used to match the plurality of matching slots 1181.

[0060] Among them, since the electrode shifting mechanism can be installed as a whole such as the driver housing 930, the driver housing 930 only requires the third housing 117 and the fourth housing 118, and there is no need to use a pressure cover to limit the rotating shaft 110, so it can better reduce the assembly process, thereby reducing production costs and improving assembly efficiency.

[0061] Among them, a guide groove 1172 is formed on the side of the third shell 117 away from the mating buckle 1171, and a limit block 119 is detachably provided at the guide groove 1172. The limit block 119 is close to the side of the fourth shell 118 and forms the wire hole 1033 together with the fourth shell 118. A countersunk hole 1191 is formed at the limit block 119, and a mounting column 1182 is correspondingly formed at the second shell 2122. A screw 1192 is provided at the countersunk hole 1191, and a threaded hole 1183 is correspondingly formed at the mounting column 1182. The screw 1192 is used to threadably cooperate with the threaded hole 1183.

[0062] Example 3

[0063] Seen in Figure 13-15 This embodiment provides an electrode shifting mechanism, which differs from the electrode shifting mechanism in Embodiments 1 and 2 in that a protrusion 14211 is formed on the side of the shift spring 221 close to the positive electrode plate 214 of the power supply, and the protrusion 14211 is used to cooperate with the selection hole 322. The shift spring 221 is formed with three third matching holes 14212 along the circumferential direction, and the third matching holes 14212 are used to cooperate with the first matching holes 323.

[0064] Furthermore, a second contact point 1351 is formed on the side of the positive electrode connecting piece 115 close to the shift knob 120 .

[0065] Specifically, there are 4 first matching holes 323 and 3 third matching holes 14212, corresponding to L1, L2 and L3 respectively, and the first matching hole 323 of the shift spring 221 without an opening corresponds to N. Therefore, when the second contact point 1351 at the positive connecting piece 115 is in contact with the first matching hole 323, the matching feel at the position with the third matching hole 14212 is different from that at the position without an opening, so it is convenient for users to operate blindly when shifting.

[0066] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0067] Assembly principle: Install the shift knob 120 on the mounting base 2111, then place the two as a whole on the third shell 117, place the PCB circuit board, positive connecting piece 115 and negative connecting piece 116 on the third shell 117, and finally snap the fourth shell 118 into the third shell 117 to complete the assembly of the four-wire track power driver.

[0068] Working principle: Figure 16As shown, the four-wire track power driver is inserted into the four-wire track 150. Plastic brackets 151 are provided on both sides of the inner wall of the four-wire track 150. The plastic brackets 151 are used to fix one negative wire 153 and three positive wires 152. When in use, the shaft lever 1115 is manually turned to make one negative power electrode sheet 213 and three positive power electrode sheets 214 extend out of the driver housing 930, so that the negative power electrode sheet 213 contacts the negative wire 153, and the three positive power electrode sheets 214 contact the positive wire 152, thereby realizing the installation of the four-wire track power driver on the four-wire track.

[0069] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The embodiments shown are only part of the embodiments of the present invention, and the actual structure is not limited to them. Therefore, if a person skilled in the art is inspired by the above and designs a structure and embodiment similar to the technical solution without creatively designing it without departing from the inventive purpose of the present invention, it shall fall within the scope of protection of the present invention.
