[0036] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] The present utility model provides a battery switch with a digital display function. As Figures 1 to 10 shown, the battery switch mainly includes three parts: a knob 1, a digital display component 3, and a main body 2. Among them, the main body 2 is used to connect to the battery 10 and serves as the basic support structure of the battery switch; the knob 1 is rotatably arranged on the main body 2 and is the main part for users to operate. By rotating the knob 1, the on-off of the battery 10 can be controlled; while the digital display component 3 constitutes the display system of the switch and can display key parameters such as the power, voltage, and current of the battery 10 in real time, providing users with an intuitive and convenient use experience.

[0038] With key reference to Figure 2 and Figure 4 , the knob 1 includes a knob upper cover 11 and a knob lower cover 12 fixedly connected through a buckle structure 13. A rotating shaft 4 is connected to the bottom of the knob lower cover 12. A connecting piece 5 is connected to the lower end of the rotating shaft 4, and two first contacts 51 are provided on the connecting piece 5. The main body 2 includes a main body upper cover 21 and a main body lower cover 22 fixed together by screws, and a cavity is formed between the two. Two second contacts 23 are provided in the cavity. Moreover, a through hole 211 is opened in the middle of the main body upper cover 21, and the lower end of the rotating shaft 4 passes through the through hole 211 and is placed in the cavity, and the connecting piece 5 is also located in the cavity. When the user rotates the knob 1, the knob 1 drives the rotating shaft 4 to rotate, and then drives the connecting piece 5 to rotate. When the first contact 51 on the connecting piece 5 rotates to contact the second contact 23, the circuit is connected; and when the first contact 51 rotates to separate from the second contact 23, the circuit is disconnected.

[0039] In this embodiment, as Figure 7 shown, the two second contacts 23 are respectively riveting process contacts located on the input contact piece 24 and the output contact piece 25. Both contact pieces are fixed on the main body lower cover 22 through screw and nut assemblies. Among them, an input battery terminal joint 241 is connected to the outer end of the input contact piece 24 for connecting to the negative battery terminal 102; while an output battery terminal joint 251 is connected to the outer end of the output contact piece 25, and the output battery terminal joint 251 is connected to other devices, such as an electrical device 9, and the positive polarity is connected to the battery positive electrode 101 through a wire, so that a complete circuit is formed between the positive and negative electrodes of the battery 10.

[0040] In this embodiment, as Figure 4As shown, the rotating shaft 4 is designed as a copper column integrally injection-molded with the lower cover 12 of the knob. The outer periphery of the rotating shaft 4 is square. Correspondingly, a square hole 52 matching the outer periphery of the rotating shaft 4 is provided in the middle of the connecting piece 5. The rotating shaft 4 passes through the square hole 52 of the connecting piece 5 to achieve circumferential limitation, ensuring synchronous rotation between the rotating shaft 4 and the connecting piece 5.

[0041] Key reference Figure 2 、 Figure 5 and Figure 6 , for the part of the rotating shaft 4 located in the cavity, an isolator 6, a gear position piece 7 and an elastic piece 8 are adaptively sleeved on its outer periphery. The upper part of the isolator 6 is an annular column, the lower part is a rectangular column, and the middle part is square and matches the outer periphery of the rotating shaft 4. The isolator 6 is sleeved on the outer periphery of the rotating shaft 4 and can rotate synchronously with the rotation of the rotating shaft 4. In addition, a snap ring groove 41 is provided on the rotating shaft 4, and the snap ring groove 41 is located below the isolator 6, and a snap ring 42 is embedded in the snap ring groove 41. The snap ring 42 can limit the axial movement of the rotating shaft 4, thus ensuring that the rotating shaft 4 will not come out during use.

[0042] The middle part of the gear position piece 7 is square and matches the outer periphery of the square column of the isolator 6. The gear position piece 7 is sleeved on the outer periphery of the isolator 6 and can rotate synchronously with the rotation of the rotating shaft 4 and the isolator 6. The gear position piece 7 will produce a sense of pause when the knob 1 rotates to the in-place position. The sense of pause allows the user to more clearly perceive that the knob 1 has rotated to the predetermined position, thus increasing the accuracy and reliability of the operation.

[0043] The elastic piece 8 is located between the gear position piece and the connecting piece 5. As Figure 5 and Figure 6 shown, the elastic piece 8 in this embodiment adopts a compression spring. The upper end of the compression spring abuts against the gear position piece, and the lower end abuts against the connecting piece 5. When the rotating shaft 4 rotates to drive the two first contacts 51 to contact the second contact 23 to connect the circuit, the compression spring can apply pressure to the connecting piece 5. The function of this pressure is to firmly press the first contact 51 on the connecting piece 5 against the second contact 23, ensuring the stability and reliability of the circuit connection. Through such a design, not only the connection quality of the circuit is improved, but also the circuit failure caused by loose contacts or poor contact is effectively prevented.

[0044] The key of the present utility model lies in the digital display component 3. As Figure 3 and Figure 4As shown, the digital display component 3 includes a digital display circuit board 31 and a digital display screen 32, and the two parts are electrically connected to achieve data intercommunication. Among them, the digital display circuit board 31 is responsible for receiving, processing and converting signals from external sensors or input devices 9, and converting them into a data format that can be displayed by the digital display screen 32. The digital display screen 32 is responsible for intuitively displaying these processed data in the form of numbers, characters or graphics for users to read. The digital display screen 32 described in this case can be an LCD digital display screen 32 or an LED digital display screen 32.

[0045] In this embodiment, the digital display assembly 3 is located inside the knob 1, but does not rotate synchronously with the knob 1, but is fixed to the main body 2. Specifically, a receiving cavity is formed between the knob upper cover 11 and the knob lower cover 12, and the digital display assembly 3 is placed in the receiving cavity. In order to enable the user to conveniently view the information on the digital display screen 32, a window 111 is opened on the top of the knob upper cover 11. In addition, in order to protect the digital display screen 32 and enhance the visual effect, a transparent lens 112 is also installed at the window 111, and the lens is firmly bonded to the knob upper cover 11 by means of adhesive.

[0046] The specific fixing method and structure between the digital display component 3 and the main body 2 are as follows: two mounting posts 26 are centrally symmetrically arranged on the main body lower cover 22, and these two mounting posts 26 play a key supporting and fixing role. At the same time, a clearance hole 212 is correspondingly provided on the main body upper cover 21, and a clearance groove 121 is provided on the knob lower cover 12. The upper end of the mounting post 26 extends upward, passes through the clearance hole 212 of the main body upper cover 21 and the clearance groove 121 of the knob lower cover 12 in turn, and then enters the accommodating cavity of the knob 1. During the rotation of the knob 1, the mounting post 26 is avoided by the clearance groove 121 without causing interference. It should be noted that the arc of the clearance groove 121 is sufficient for the knob 1 to rotate 90 degrees. In the accommodating cavity, the digital display circuit board 31 is firmly fixed to the two mounting posts 26 by screws, thereby ensuring the stability and reliability of the digital display component 3.

[0047] like Figure 7 As shown, a positive connection conductor 27 and a negative connection conductor 28 are provided in the cavity of the main body, both of which are connected to the digital display circuit board 31 and are used to supply power to the digital display circuit board 31. The two connection conductors are attached to a mounting post 26. One end of the positive connection conductor 27 is connected to the positive connection post 29, and the other end is welded to the positive electrode welding point 311 on the digital display circuit board 31; one end of the negative connection conductor 28 is welded to the negative electrode welding point 312 on the digital display circuit board 31, and the other end is connected to the output contact piece 25, and is pressed by a screw nut assembly.

[0048] In this embodiment, the application scenario of the battery switch with digital display function is as follows: Figure 10As shown in the figure, the battery switch is installed on the battery 10. The input battery terminal connector 241 of the battery switch is connected to the negative battery terminal 102, while the output battery terminal connector 251 is connected to the electrical equipment 9. The positive connection column 29 is connected to the positive battery terminal 101 through a connecting wire to supply power to the digital display screen 32.

[0049] The working principle of the battery switch with a digital display function of the present utility model is as follows:

[0050] Initial state: When the switch is in the off state, the two first contacts 51 on the connecting piece 5 are disconnected from the two second contacts 23, the circuit is not connected, and the digital display screen 32 may display "OFF" or have no display, indicating that the switch is off and the circuit is not connected.

[0051] Turning on the switch: The user starts to turn the knob 1. As the knob 1 rotates, the two first contacts 51 on the connecting piece 5 gradually approach the two second contacts 23. When the knob 1 is rotated in place, the two first contacts 51 are completely connected to the two second contacts 23, and at this time, the circuit forms a path. The digital display screen 32 lights up accordingly and displays key parameters such as the power, voltage, and current of the battery 10 in real time, providing intuitive battery 10 status information for the user.

[0052] Turning off the switch: When the user needs to turn off the switch, the user rotates the knob 1 in the reverse direction. As the knob 1 rotates in the reverse direction, the two first contacts 51 on the connecting piece 5 gradually move away from the two second contacts 23. When the knob 1 is completely rotated in the reverse direction in place, the two first contacts 51 are completely disconnected from the two second contacts 23, and the circuit is disconnected. The indication on the digital display screen 32 goes out or displays "OFF", indicating that the switch has been turned off and the circuit has been disconnected.

[0053] To further illustrate the embodiments, the present utility model provides drawings. These drawings are part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0054] At the same time, the front, rear, left, right and other directions involved in this embodiment are only for reference of a direction and do not represent the directions in actual use. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
