Description

Technical Field

[0001] This utility model relates to the field of cold drink machine technology, specifically a circuit board assembly structure for a cold drink machine. Background Technology

[0002] Chinese utility model patent CN202422200904.0 discloses a drive plate heat dissipation mechanism and a beverage cooler. It includes a drive housing for installation in the beverage cooler and a cover covering the drive housing, forming a drive cavity. A drive plate is located within the drive cavity, and a through-hole is provided at one end of the drive cavity, allowing the drive cavity to communicate with the external space. Multiple heat dissipation holes are spaced apart on the cover, communicating with the drive cavity and located near the beverage cooler's ventilation plate. The drive housing is vertically installed on the motor mount in the beverage cooler. While this reduces horizontal space occupation, the drive housing is parallel to the beverage cooler's heat dissipation holes after installation, hindering smooth airflow. Fresh air enters the beverage cooler and contacts the drive housing, but heated air cannot be promptly guided out; hot air flows back onto the drive housing surface, blocking the entry of fresh air from the heat dissipation holes, resulting in poor heat dissipation. Therefore, further improvement is necessary. Utility Model Content

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-9 The circuit board assembly structure of this cold drink machine includes a base 1 and a circuit board 2. A circuit board assembly box 3 is provided on the base 1, and the circuit board 2 is placed inside the circuit board assembly box 3. The circuit board assembly box 3 is vertically fixed on the base 1. The cold drink machine is also provided with heat dissipation and ventilation holes 4. The outer vertical surface of the circuit board assembly box 3 is inclined and corresponds to the heat dissipation and ventilation holes 4.

[0025] The base 1 is provided with an outer perimeter plate 5, which includes a rear wall plate 5.1, a left wall plate 5.2 and a right wall plate 5.3 extending forward from the left and right edges of the rear wall plate 5.1, respectively. The rear wall plate 5.1, the left wall plate 5.2 and the right wall plate 5.3 are integrally formed or separately set and then fixedly connected to form an outer perimeter plate 5 that keeps the top, bottom and front open.

[0026] In this embodiment, the rear wall panel 5.1, the left wall panel 5.2, and the right wall panel 5.3 are integrally formed.

[0027] The circuit board assembly box 3 is inclined relative to the rear wall panel 5.1, or the left wall panel 5.2, or the right wall panel 5.3. The outer vertical surface of the circuit board assembly box 3 forms an angle α with the inner wall surface of the rear wall panel 5.1, or the left wall panel 5.2, or the right wall panel 5.3. The angle α is an acute angle.

[0028] In this embodiment, the circuit board assembly box 3 is inclined relative to the right side wall panel 5.3, and the outer vertical surface of the circuit board assembly box 3 forms an angle α with the inner wall surface of the right side wall panel 5.3. The angle α is an acute angle.

[0029] In this embodiment, the included angle α is 30°, so that the included angle α between the outer vertical surface of the circuit board assembly box 3 and the inner wall surface of the right side wall panel 5.3 faces the heat dissipation ventilation hole 4 of the rear wall panel 5.1; the air entering from the heat dissipation ventilation hole 4 of the right side wall panel 5.3 flows through the outer vertical surface of the circuit board assembly box 3, contacts the outer vertical surface of the circuit board assembly box 3 and is guided to flow out through the heat dissipation ventilation hole 4 of the rear wall panel 5.1, and the airflow is guided to achieve convection heat dissipation.

[0030] In other embodiments, the included angle α can also be set to 89°, 70°, 60°, 50°, 40°, etc.

[0031] In one embodiment, the circuit board assembly box 3 is vertically fixed on the base 1 near the left side panel 5.2. The circuit board assembly box 3 is inclined relative to the left side panel 5.2, so that the outer vertical surface of the circuit board assembly box 3 forms an angle α with the inner wall surface of the left side panel 5.2. The opening of the angle α faces the heat dissipation ventilation hole 4 of the rear panel 5.1, which can also realize air circulation and form a heat dissipation channel, which will not be described in detail here.

[0032] The heat dissipation and ventilation holes 4 are elongated and are spaced apart on the rear wall panel 5.1, the left wall panel 5.2 and the right wall panel 5.3.

[0033] Long, narrow ventilation holes 4 are spaced apart on the rear wall panel 5.1, left wall panel 5.2, and right wall panel 5.3, allowing airflow through all three panels and forming a heat dissipation channel. The orientation of each ventilation hole 4 on the rear wall panel 5.1, left wall panel 5.2, and right wall panel 5.3 can be arbitrarily set longitudinally, horizontally, or obliquely.

[0034] In addition, the heat dissipation and ventilation holes 4 can also be other shapes, such as round, square, or prismatic, as long as air can flow in.

[0035] A ventilation gap is left between the bottom of the circuit board assembly box 3 and the base 1.

[0036] Because there is a ventilation gap between the bottom of the circuit board assembly box 3 and the base 1, a bottom air convection channel is formed, which can increase the air flow between the bottom of the circuit board assembly box 3 and the base 1. In addition, the bottom of the base 1 is also provided with a base heat dissipation hole 1.1. The airflow flows from the base heat dissipation hole 1.1 to the heat dissipation ventilation hole 4 of the outer plate 5. The two form a heat dissipation channel, so that the base heat dissipation hole 1.1 and the heat dissipation ventilation hole 4 are combined to achieve three-dimensional heat dissipation of the circuit board assembly box 3 and improve the heat dissipation efficiency of the circuit board assembly box 3.

[0037] The circuit board assembly box 3 includes a box body 6 and a cover plate 7. The box body 6 is square and one side is open. The cover plate 7 is fixedly installed on the open side of the box body 6, and the two form an assembly cavity. The circuit board 2 is located in the assembly cavity.

[0038] In this embodiment, the cover plate 7 and the box body 6 can be fixed together by fasteners. Specifically, fastening holes are provided at corresponding positions on the cover plate 7 and the box body 6, and the fasteners act on these holes to secure the cover plate 7 and the box body 6. Alternatively, the cover plate 7 and the box body 6 can also be fixed together by snap-fit. Specifically, snap-fit ​​pieces and snap-fit ​​holes are provided at corresponding positions on the cover plate 7 and the box body 6, and the snap-fit ​​pieces engage with the snap-fit ​​holes to secure the cover plate 7 and the box body 6.

[0039] The box body 6 or the cover plate 7 is provided with wire holes.

[0040] In this embodiment, a wire-through hole is provided on the housing 6, and the power lines on the circuit board 2 extend to the outside of the assembly cavity through the wire-through hole.

[0041] The bottom of the box body 6 or the cover plate 7 is provided with a positioning post 8, and the base 1 is provided with a support post 9. The positioning post 8 and the support post 9 are positioned and inserted into each other, and the two are fixed to each other by fasteners.

[0042] Specifically, the box body 6 is provided with a first extension 10 and a second extension 11. The first extension 10 extends toward the outer side of the bottom of the box body 6, and the second extension 11 extends toward the outer side of the open bottom of the box body 6. There is a gap between the first extension 10 and the second extension 11, and positioning posts 8 are respectively provided at the bottom of the two.

[0043] During assembly, the support column 9 is pre-positioned and inserted into the positioning column 8 to pre-position the box 6 and the base 1. Then, the fasteners are used to fasten the support column 9 and the positioning column 8 to fix the box 6 and the base 1.

[0044] The circuit board 2 is fixedly mounted on the box 6 by fasteners, clips, or adhesive.

[0045] In this embodiment, the box body 6 is provided with a buckle and a fastening hole, and the circuit board 2 is provided with a fastening mating hole. The circuit board 2 is pre-clamped on the buckle, and then the fasteners are used to fasten the fastening hole and the fastening mating hole, so that the circuit board 2 and the box body 6 can be fixed.

[0046] The base 1 is provided with an opening 12 for the power cord to be led out. The base 1 is provided with a wire clamping and fixing part 13 on the upper side of the opening 12 and a stop part 14 on the lower side of the opening 12, corresponding to the power cord.

[0047] In this embodiment, a wire clamping component is fixedly connected to the wire clamping fixing part 13 by fasteners. The wire clamping component is used to clamp the power cord to improve the assembly stability of the power cord. The stop part 14 is set on the lower side of the opening 12, which not only prevents foreign objects from entering the interior of the cold drink machine through the opening 12, but also limits the position of the power cord extending through the opening 12, so that the power cord can extend to the designated position.
