Description

Technical Field

[0001] This utility model relates to a generator starter switch, and more particularly to a starter switch with parameter display. Background Technology

[0002] The existing generator start switch is a two-position rotary switch with a key, including a base, a starter rotor, and a lock cylinder. The starter rotor shaft is positioned inside the cavity of the base, and the shaft end is connected to the lock cylinder. Inserting a key into the lock cylinder rotates the starter rotor to either the open or closed position. Corresponding electrodes are provided between the contact surfaces of the starter rotor and the base, allowing for on / off selection and completing the starting function. The generator is also equipped with a voltage and other parameter display to indicate the operating status. Currently, these two components are independently located in their respective positions on the generator, causing inconvenience in cable routing and use.

[0003] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0004] The purpose of this invention is to design a generator start switch with a knob that has a built-in display meter.

[0005] The present invention is implemented as follows: a generator starter switch includes a base, a starter rotor, and a knob; characterized in that: the starter rotor is rotatably positioned at the rear end of the base via a hollow shaft, and the knob located at the front end of the base is fixed to the end of the hollow shaft, and the knob drives the starter rotor to rotate to the open or closed position; the hollow part of the knob is sequentially equipped with a PCB board for an onboard display, a sealing plate, and a light-transmitting plate from the inside out; the wires of the PCB board pass through the hollow shaft of the starter rotor and are led out from the rear end of the base.

[0006] The sealing plate has an axial cross section of an "I" shaped rotating body with a cylindrical edge. It is nested in the front end of the hollow part of the knob by means of the cylindrical edge. The inner end of the cylindrical edge abuts against the PCB board or the stepped part formed in the hollow part of the knob. The abutting part is waterproofed by a sealing ring or adhesive. The light-transmitting plate is embedded and attached to the front end face of the sealing plate.

[0007] The hollow part of the knob and the edge of the sealing plate are provided with screw posts and screw holes, which are fastened together by screws; the light-transmitting plate is made of black light-transmitting material and is attached to the front end of the sealing plate with double-sided adhesive.

[0008] As a preferred embodiment, the sealing plate is an opaque material with a cutout corresponding to the position of the display screen on the PCB board. When assembled, the display screen is flush with the sealing plate, and adhesive is applied to seal the junction between the two.

[0009] As a preferred embodiment, the sealing plate is a light-transmitting plate that completely covers the display screen surface of the PCB board.

[0010] This utility model combines the start knob and the display parameter meter into one, which is not only intuitive but also reduces the space occupied by the display meter, bringing convenience to the user; it has the characteristics of unique concept, reasonable design and seamless replacement of traditional start switches.

[0021] 6—Light-transmitting panel; Detailed Implementation

[0022] Reference Figures 1 to 3 The generator start switch includes a base 1, a starter rotor 2, and a knob 3. The main body of the base 1 is a rotating structure with a front chamber 11 and a rear chamber 12. The former is used to cooperate with the knob 3, and the latter is used to install the starter rotor 2. For this purpose, an end cover 13 is also provided at the rear end.

[0023] The starting rotor 2 is rotatably positioned at the rear end of the base 1 via the hollow shaft 21, i.e., installed in the rear chamber 12, forming electrode contact and disconnection with the base 1. The knob 3 is rotatably disposed at the front end of the base 1, i.e., in the front chamber 11, and fixed to the end of the hollow shaft 21, forming rotational synchronization. The knob 3 drives the starting rotor 2 to rotate to the on or off position. The hollow part 31 of the knob is equipped with a PCB board 4, a sealing plate 5, and a light-transmitting plate 6 from the inside out. The PCB board 4 has an onboard display screen 41. The wires 42 pass through the hollow shaft 21 of the starting rotor and are led out from the rear end of the base 1, so they do not tangle when starting or stopping the rotation. The display screen 41 displays the generator's voltage and other parameters in real time.

[0024] To meet waterproofing requirements,

[0025] The sealing plate 5 has an axial cross section of an "I"-shaped rotating body with a cylindrical edge 51. The cylindrical edge 51 is nested in the front end of the hollow part 31 of the knob. The inner end of the cylindrical edge 51 abuts against the PCB board 4 or the stepped part 32 formed in the hollow part 31 of the knob. The abutting part is waterproofed by a sealing ring or adhesive, preventing rainwater from seeping into the hollow part 31 of the knob on the PCB board 4 from the light-transmitting plate side. The light-transmitting plate 6 is embedded and attached to the front end face of the sealing plate 5. The front end of the cylindrical edge 51 forms a sealing edge.

[0026] Furthermore, screw posts 33 and screw holes 53 are distributed between the hollow part 31 of the knob and the edge of the sealing plate 5, and the two are fastened together by screws; the light-transmitting plate 6 is made of black light-transmitting material and is attached to the front end face of the sealing plate 5 with double-sided adhesive, simplifying the assembly and maintenance process.

[0027] There are two options for the sealing plate 5. One, as shown in the example, is an opaque material with a cutout 52 corresponding to the position of the display screen 41 on the PCB board. When assembled, the display screen 41 is flush with the sealing plate 5, and the junction between the two is sealed with adhesive. This combination provides the best display effect, and the rest of the PCB board 4 is blocked, forming a good visual separation.

[0028] Secondly, the sealing plate 5 is a light-transmitting plate 6, which covers the surface of the display screen 41 on the PCB board. It is simple and has good sealing performance, but it cannot block the PCB board 4 and can only filter it with the help of the black light-transmitting plate 6.
