[0020] (III) Beneficial Effects

[0021] This invention provides an easy-to-maintain electronic controller. It replaces the charging terminals of traditional electronic controllers with fasteners and conductive components. The fasteners and conductive components are fixed to the sockets on the circuit board by mutual disassembly. The first conductive block of the conductive component contacts the first conductive layer at the edge of the socket to achieve electrical connection. Compared to existing electrical connection methods, this design eliminates the need for spot welding, reducing production costs and eliminating welding fume hazards. Furthermore, because the fasteners and conductive components clamp the circuit board via the abutment and the first conductive block, the charging unit can be stably mounted on the circuit board, ensuring stable contact between the first conductive block and the first conductive layer. Therefore, it is difficult for the conductive components to break during disassembly and assembly, reducing the possibility of product damage, ensuring product stability, and extending product lifespan. On the other hand, since the fasteners and conductive components can be disassembled and reassembled at the circuit board sockets, the disassembly and assembly of the charging unit and the circuit board is very convenient, further improving maintenance convenience and effectively reducing maintenance costs.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0041] See appendix Figure 1 - Appendix Figure 6 An easy-to-maintain electronic controller includes a housing 1, a battery 2, a control unit 3, and a charging unit 4. The housing 1 has an internal cavity 10 for housing the battery 2. The control unit 3 includes a circuit board 31 installed within the cavity 10 and electrically connected to the battery 2. The circuit board 31 has two sockets 310, and each socket 310 has a first conductive layer 311 at its edge. Both first conductive layers 311 are located on the front of the circuit board 31, serving as the positive and negative terminals of the circuit board 31, respectively. The charging unit 4 is disposed within the cavity 10 and includes fasteners 41 and conductive elements 42. The ends of the fastener 41 and the conductive element 42 are detachably connected within the socket 310. The fastener 41 has a stop block 411 that abuts against the back of the circuit board 31, and the conductive element 42 has a first energized block 421 that contacts the first conductive layer 311 and penetrates the top wall of the receiving cavity 10 to the outside. The first conductive layer 311 and the conductive element 42 are both made of conductive material. The charging part 4 has two sets of charging parts that are installed in the two sockets 310 respectively, so that the positive and negative terminals of the circuit board 31 can extend to the outside of the housing 1 and connect to the magnetic contact charging cable (not shown in the figure).

[0042] Specifically, during assembly, the ends of the fasteners 41 and the conductive parts 42 are first inserted into the sockets 310 and connected, so that the abutment 411 and the first energized block 421 abut against the back of the circuit board 31 and the first conductive layer 311 respectively, so that the charging part 4 can be installed on the circuit board 31 to achieve electrical connection; then the circuit board 31 is installed into the receiving cavity 10 and the housing 1 is closed, and the first energized block 421 is ensured to penetrate through the top wall of the receiving cavity 10 to the outside.

[0043] In use, the battery 2 supplies power to the circuit board 31, and the circuit board 31 can receive and transmit signals using its built-in signal module (not shown in the figure), so that users can receive and issue control commands using the electronic controller. If the battery 2 is low on power, the user can use a magnetic contact charging cable to connect the first power block 421 of the two conductive parts 42, and then charge the battery 2 with the help of the circuit board 31.

[0044] During maintenance, staff can directly open the housing 1 to expose the circuit board 31 and then repair the components on the circuit board 31. If the charging part 4 is damaged, the user can drive the end of the fastener 41 and the end of the conductive part 42 to separate from each other, remove the conductive part 42 and the fastener 41 from the circuit board 31, and then reinstall the new end of the fastener 41 and / or the conductive part 42 onto the circuit board 31 according to the above assembly steps, and then reseal the housing 1.

[0045] In summary, this utility model uses fasteners 41 and conductive elements 42 to replace the charging terminals (not shown in the figure) of traditional electronic controllers. Fasteners 41 and conductive elements 42 are fixed to the sockets 310 on the circuit board 31 by mutual disassembly. Electrical connection is achieved by the first conductive block 421 of the conductive element 42 contacting the first conductive layer 311 at the edge of the socket 310. Compared to existing electrical connection methods, this design eliminates the need for spot welding, reducing production costs and preventing welding fume hazards. Furthermore, because fasteners 41 and conductive elements 42 are respectively connected by the abutment block 411 and the first conductive layer 311 at the edge of the socket 310, this design also provides a more efficient and reliable electrical connection. A power block 421 clamps the circuit board 31, allowing the charging unit 4 to be stably mounted on the circuit board 31 and ensuring stable contact between the first power block 421 and the first conductive layer 311. Therefore, it is difficult to cause the conductive component 42 to break contact during the disassembly and assembly of the housing 1, thereby reducing the possibility of product damage, ensuring the stability of product use and extending the product's service life. On the other hand, since the fastener 41 and the conductive component 42 can be disassembled and reassembled through the socket 310 of the circuit board 31, the disassembly and assembly of the charging unit 4 and the circuit board 31 are very convenient, further improving maintenance convenience and effectively reducing maintenance costs.

[0046] See appendix Figure 1 - Appendix Figure 5In this embodiment, the electronic controller is a food dispensing device. The control unit 3 also includes a button 32, a display screen 33, and a buzzer (not shown) that are electrically connected to the circuit board 31. The button 32, the display screen 33, and the buzzer are all mounted on the housing 1. After receiving the instruction from the circuit board 311, the buzzer can emit a sound to prompt the user. The button 32 allows the user to operate the circuit board 31 to turn off the buzzer. The display screen 33 is used to display the data information of the circuit board 31, such as the power of the battery 2.

[0047] Furthermore, in other embodiments, the electronic controller can also be an electronic key (not shown), a remote control (not shown), or other products. In this case, the control unit may include buttons electrically connected to the circuit board. The buttons are mounted on the housing for the user to operate the circuit board. The circuit board may also be equipped with wireless modules (not shown) such as WiFi modules and Bluetooth modules for transmitting signals. As for components such as the display screen and buzzer, they can be selectively provided.

[0048] It should be noted that, since there are various types of electronic controllers on the market and the components of the control unit of different electronic controllers are also different, this utility model does not limit the types of electronic controllers or the components of the control unit.

[0049] See appendix Figure 1 - Appendix Figure 6 The fastener 41 is also made of conductive material, and the first end of the fastener 41 has a second energized block 412 that penetrates the bottom wall of the receiving cavity 10 to the outside.

[0050] Specifically, in this design, the positive and negative terminals of the circuit board 31 can extend synchronously to the top and bottom of the housing 1, facilitating the connection of the magnetic contact charging cable to two first energizing blocks 421 or two second energizing blocks 412 at the top or bottom of the housing 1 to charge the battery 2. On the other hand, by stacking two housings 1 on each other, the two first energizing blocks 421 can contact the two second energizing blocks 412 one-to-one, thereby completing the circuit conduction of multiple electronic controllers. At this time, the magnetic contact charging cable connects the two first energizing blocks 421 at the top or the two second energizing blocks 412 at the bottom, which can charge multiple electronic controllers simultaneously. Therefore, when both the fastener 41 and the conductive parts 42 are made of conductive materials, the functions and usage scenarios of the electronic controllers can be enriched, further improving the user experience.

[0051] See appendix Figure 3 - Appendix Figure 6Each of the two sockets 310 is provided with a second conductive layer 312 made of conductive material at its edge. The two second conductive layers 312 are located on the back of the circuit board 31 to serve as the positive and negative electrodes of the circuit board 31, respectively. The abutment 411 of the fastener 41 contacts the second conductive layer 312. This design allows the fastener 41 to be electrically connected to the circuit board 31 directly without the aid of the conductive component 42, thereby further improving the power supply stability of the fastener 41.

[0052] It should be noted that the conductive material can be copper, iron, aluminum alloy, graphene, etc. Due to the variety of related materials, this utility model does not limit the types. For ease of understanding, in this embodiment, the fastener 41, the conductive component 42, the first conductive layer 311 and the second conductive layer 312 are all made of copper.

[0053] See appendix Figure 3 - Appendix Figure 13 The fastener 41 has a threaded sleeve 410 at its end, and the fastener 41 has a threaded hole 4100 extending through the threaded sleeve 410. The conductive component 42 has a stud 420 at its end, and the stud 420 is threadedly connected to the threaded hole 4100.

[0054] Specifically, during assembly, the screw sleeve 410 and stud 420 are first inserted into the socket 310 and threaded together for fixation, so that the abutment 411 and the first energized block 421 abut against the back of the circuit board 31 and the first conductive layer 311 respectively, thereby installing the charging part 4 on the circuit board 31 and achieving electrical connection; during disassembly, the conductive part 42 is rotated to drive the stud 420 to disengage from the screw sleeve 410, thereby removing the conductive plate from the circuit board 31.

[0055] It should be noted that, in addition to using threaded connections, the ends of fastener 41 and conductive parts 42 can also be connected by magnetic attraction, snap-fit ​​connection, etc. to achieve mutual disassembly. Since there are various types of related detachable structures, this utility model does not limit them.

[0056] See appendix Figure 11 - Appendix Figure 13 The length of the end of the fastener 41 is h1, and the height of the socket 310 is h2, where 0 < h1 ≤ h2. This ensures that when the stud 420 enters the socket 310 and is fully connected to the screw hole 4100, the abutment block 411 and the first energizing block 421 stably clamp the circuit board 31 to prevent the fastener 41 and the conductive component 42 from shaking on the circuit board 31, thereby further improving the installation stability of the charging part 4. At the same time, it also ensures that the first energizing block 421 is in close contact with the first conductive layer 311 to reduce the risk of disconnection and ensure smooth power supply.

[0057] See appendix Figure 6 - Appendix Figure 10The top surface of the first power block 421 protrudes to the top surface of the housing 1, and the distance between the top surface of the first power block 421 and the top surface of the housing 1 is d1; the bottom of the housing 1 is provided with a notch 120, and the second power block 412 is located in the notch 120, and the distance between the top surface of the second power block 412 and the bottom surface of the housing 1 is d2, d2 < d1; this design allows the first power block 421 to enter the notch 120 and contact the second power block 412 when the two housings 1 are stacked, thereby avoiding the mutual offset between the two electronic controllers after stacking, reducing the risk of disconnection between the first power block 421 and the second power block 412, and ensuring charging stability.

[0058] See appendix Figure 3 - Appendix Figure 4 and attached Figure 14 - Appendix Figure 16 The top of the housing 1 is provided with a positioning block 111 and the bottom of the housing 1 is provided with a positioning port 121. When the two housings 1 are stacked, the positioning block 111 is inserted into the positioning port 121. The cooperation of the positioning block 111 and the positioning port 121 can enable the first energized block 421 to quickly align and contact the second energized block 412, thereby improving the user experience. The positioning block 111 and the positioning port 121 also have a limiting function, which can prevent the two stacked housings 1 from shifting.

[0059] See appendix Figure 3 - Appendix Figure 10 and attached Figure 14 - Appendix Figure 16 The positioning block 111 protrudes from the top surface of the housing 1 and the protrusion distance is d3. The positioning port 121 is recessed and the recess distance is d4, d4 < d3, and 0cm < [(d3-d2)-(d1-d2)] ≤ 1cm.

[0060] Specifically, assuming two electronic controllers are stacked on top of each other, the one on top is the first electronic controller and the one on the bottom is the second electronic controller; 0cm < [d3-d2-d1-d2] ensures that after the two electronic controllers are stacked, the first electronic controller is raised and has a certain tilt angle. Under the action of gravity, the first electronic controller can exert a certain amount of pressure on the second energized block 412 mounted on it, ensuring that the top surface of the second energized block 412 can fit more tightly with the top surface of the first energized block 421 mounted on the second electronic controller, thereby improving the energizing stability; while [d3-d2-d1-d2]≤1cm can prevent the first electronic controller from being raised too high and causing the tilt angle to be too large, thereby preventing the top surface of the second energized block 412 mounted on the first electronic controller from detaching from the top surface of the first energized block 421 mounted on the second electronic controller.

[0061] See appendix Figure 3 - Appendix Figure 10Part of the housing 1 has a cover for opening the receiving cavity 10 (not shown in the figure), while part of the housing 1 is directly composed of two parts. Since there are many types of housing 1, this utility model does not limit them. For ease of understanding, in this embodiment, the housing 1 includes a top shell 11 and a bottom shell 12 that can be disassembled and enclosed to form the receiving cavity 10. The positioning block 111 is provided on the surface of the top shell 11, and the notch 120 and the positioning port 121 are both provided on the surface of the bottom shell 12. The first energizing block 421 penetrates the surface of the top shell 11, and the second energizing block 412 penetrates the bottom shell 12 into the notch 120.

[0062] Specifically, the combined use of the top shell 11 and the bottom shell 12 enables the assembly and disassembly of the shell 1 and the opening and closing of the receiving cavity 10, facilitating the disassembly and maintenance of the battery 2, circuit board 31, and charging unit 4. Furthermore, the disassembly of the top shell 11 and the bottom shell 12 will not affect the contact between the charging unit 4 and the circuit board 31. On the other hand, the top shell 11 and the bottom shell 12 can be connected by snap-fit ​​or by screws to achieve mutual disassembly. Since the relevant disassembly structure is relatively conventional, it will not be described in detail in this utility model.

[0063] See appendix Figure 3 - Appendix Figure 8 The first energized block 421 is also provided with a rotating block 422. When the first energized block 421 contacts the first conductive layer 311, the rotating block 422 abuts against the inner surface of the top shell 11.

[0064] Specifically, the rotating block 422 can serve as the point of force for the first energized block 421, making it convenient to drive the conductive component 42 by rotating the rotating block 422; on the other hand, the assembled top shell 11 can also apply pressure to the first energized block 421 through the rotating block 422, so that the first energized block 421 can contact the first conductive layer 311 more stably, so as to further prevent the conductive component 42 from shifting during use.

[0065] See appendix Figure 6 - Appendix Figure 9 The present invention also includes a magnet 5, which is installed on the inner wall of the receiving cavity 10. This design enables the housing 1 to have an adsorption capacity, so that the electronic controller can be adsorbed and fixed on a magnetic desktop, wall or other place, further improving the ease of use.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
