[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 and Figure 2As shown, this application provides a controller, including a housing 1, a functional circuit board 2, and an interactive panel 3. The heat dissipation base 11 is an integrally formed structure, including a first base plate portion 111 and a second base plate portion 112 arranged perpendicularly to each other. The second base plate portion 112 extends vertically from one edge of the first base plate portion 111, and the remaining side edges of the first base plate portion 111 are provided with outwardly protruding mating protrusions 1111. The cover plate 12 is positioned by mating with the second base plate portion 112 and together with the heat dissipation base 11, forms a mounting cavity with one open side. The functional circuit board 2 is installed in the mounting cavity, and the heating elements arranged on its surface are in direct contact with the first base plate portion 111 of the heat dissipation base 11, achieving efficient heat dissipation through the high thermal conductivity of the metal base. The interactive panel 3 is sealed and installed at the open end of the housing 1, forming a complete closed cavity together with the cover plate 12. It is electrically connected to the functional circuit board 2 via a ribbon cable or connector to complete signal transmission and human-machine interaction functions. The controller achieves efficient utilization of internal space by optimizing the structural design of housing 1, while ensuring good heat dissipation performance and structural reliability.

[0041] like Figure 2 and Figure 3 As shown, in one specific embodiment of this application, the functional circuit board 2 includes a control circuit board 21. The control circuit board 21 is fixedly mounted in the mounting cavity parallel to the first substrate portion 111 and maintains a preset distance from the first substrate portion 111. A central processing unit (CPU) is integrated on the control circuit board 21, and the CPU forms a direct heat conduction path with the first substrate portion 111 of the heat sink base 11 through a thermally conductive interface material. The spacing between the control circuit board 21 and the first substrate portion 111 satisfies heat dissipation requirements while ensuring the compactness of the overall structure. Thermally conductive silicone grease or a thermally conductive pad is used as the thermal interface material for the thermal contact between the CPU and the heat sink base 11 to reduce contact thermal resistance and improve heat dissipation efficiency.

[0042] like Figure 3 As shown in a specific embodiment of this application, a thermally conductive protrusion 1112 is provided on the mounting surface of the first substrate portion 111. The thermally conductive protrusion 1112 is integrally formed using the same metal material as the heat sink base 11. Its protrusion height ensures the formation of an optimal contact surface with the central processing unit. A thermally conductive interface material is provided on the top plane of the thermally conductive protrusion 1112 to effectively fill microscopic uneven surfaces, reduce contact thermal resistance, and thus achieve full contact with the central processing unit. To maintain stable heat transfer interface pressure, a spring screw is specially configured to continuously press the central processing unit onto the thermally conductive protrusion 1112 through elastic preload, maintaining the stability of the contact interface even under vibration conditions.

[0043] like Figure 2As shown, in one specific embodiment of this application, the functional circuit board 2 further includes a power circuit board 22, which is fixedly disposed in the mounting cavity in a manner parallel to the control circuit board 21 and maintains a preset safety distance from the control circuit board 21. The distance between the control circuit board 21 and the power circuit board 22 needs to meet the requirements of electrical safety distance and heat dissipation, while ensuring functional isolation and maintaining the compact structure of the controller.

[0044] like Figure 2 and Figure 3 As shown, in a specific embodiment of this application, the controller is provided with a first support fastener 4 and a second support fastener 5, both of which adopt a hexagonal support column structure and are fixed by a threaded connection. One end of the first support fastener 4 is connected to the mounting hole of the control circuit board 21 by a threaded engagement, and the other end is fastened to the threaded hole on the first base plate 111, forming a rigid support structure between the control circuit board 21 and the heat sink base 11. The second support fastener 5 is connected between the first base plate 111 and the second base plate 112 in the same manner. The first support fastener 4 and the second support fastener 5 can adopt two connection methods according to actual assembly requirements: one is a coaxial sequential connection method, so that the axis of the support column is kept in a straight line; the other is a staggered connection method, in which the support columns are staggered.

[0045] like Figure 2 and Figure 3 As shown in one specific embodiment of this application, a heat dissipation fin 1113 is provided on the outer surface of the first substrate portion 111. The heat dissipation fin 1113 is integrally formed with the first substrate portion 111 using the same metal material and extends into the external space of the mounting cavity. By providing multiple heat dissipation fins 1113, the maximum heat dissipation surface area is achieved within a limited space. Parallel airflow channels are formed between each heat dissipation fin 1113, facilitating airflow to remove heat. This heat dissipation structure does not affect the layout of the internal components of the controller and effectively improves the overall heat dissipation performance, making it suitable for space-constrained applications.

[0046] like Figure 4 As shown, in one specific embodiment of this application, the cover plate 12 adopts a U-shaped integrated structure, including a cover plate portion 121 and a support plate portion 122. The cover plate portion 121 is arranged parallel to the first base plate portion 111, and its two side edges extend vertically to form the support plate portions 122, with the two support plate portions 122 located at both ends of the cover plate portion 121. When the cover plate 12 is assembled with the heat dissipation base 11, the end face of the support plate portion 122 engages with the mating protrusion 1111 to achieve positioning and support of the cover plate 12.

[0047] like Figure 4As shown, in one specific embodiment of this application, the support plate 122 is provided with a plurality of heat dissipation holes 1221. These heat dissipation holes 1221 are evenly distributed in an array in the effective heat dissipation area of ​​the support plate 122. This achieves maximum ventilation and heat dissipation area while ensuring the structural strength of the support plate 122. The arrangement direction of the heat dissipation holes 1221 is consistent with the airflow direction inside the controller, forming an effective convection heat dissipation channel. This not only improves the overall heat dissipation efficiency of the controller but also reduces the weight of the support plate 122 and maintains the structural integrity of the cover plate 12.

[0048] like Figures 5 to 7 As shown, in one specific embodiment of this application, a battery insertion hole 1222 is provided on the support plate 122. The position of the battery insertion hole 1222 is aligned with the battery insertion slot on the power circuit board 22, forming a battery installation channel. The battery is installed and removed via a battery pull strip made of high-strength aramid paper material. When the battery needs to be replaced, simply pull up the exposed end of the battery pull strip to remove the battery from the battery insertion slot and complete the replacement operation through the battery maintenance port. The size of the battery insertion hole 1222 matches the standard battery specifications, facilitating battery replacement for the user. A removable battery cover 1223 is installed on the outside of the battery insertion hole 1222. The battery cover 1223 is connected to the support plate 122 by a snap-fit ​​or screw fixation method, which protects the battery installation position and maintains the integrity of the controller's appearance. The battery cover 1223 prevents dust and moisture from entering the controller's interior and facilitates battery maintenance for the user.

[0049] like Figure 5 As shown, in a specific embodiment of this application, the interactive panel 3 includes a keyboard 31, silicone buttons 32, and a cover 33. Positioning notches are provided at the upper and lower ends of the keyboard 31, which cooperate with the corresponding structures of the control circuit board 21 and the power circuit board 22 to achieve positioning. Hanging ear structures extend from the left and right sides of the keyboard 31, and these hanging ear structures form a snap-fit ​​engagement with the clearance notches provided on the cover 33. The planar layout of the keyboard 31 is divided into two functional areas: the upper part is the LCD screen mounting area, and the lower part is the tactile switch arrangement area. In addition to having a pressing structure 321 that cooperates with the tactile switches on the keyboard 31, the silicone buttons 32 also extend a thin sheet structure towards the LCD screen. This thin sheet structure forms a tight fit with the screen surface while ensuring normal display of the LCD screen. When the interactive panel 3 is fixed to the heat dissipation base 11 and the cover plate 12 by screws, the elastic pressure generated by the silicone sheet structure achieves a zero-gap fit between the LCD screen and the cover 33, effectively preventing dust and oil stains from entering the display area.

[0050] like Figure 6 and Figure 7As shown, in one specific embodiment of this application, the controller further includes a mounting base plate 6, which is connected to the outer surface of the second base plate portion 112. The mounting base plate 6 and the second base plate portion 112 are aligned via a locating pin 61, wherein the locating pin 61 protrudes vertically from the mounting surface of the mounting base plate 6, and the second base plate portion 112 has a matching locating hole (not shown). The mounting base plate 6 also has multiple mounting holes to facilitate a reliable connection with an external mounting base via bolts or other fasteners.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
