Description

Technical Field

[0001] The utility model relates to the technical field of controllers, in particular to a controller which is easy to clean. Background Art

[0002] The controller that uses solar energy to charge efficiently is an important part of the solar power generation system. Its main function is to control the voltage and current of the solar cell to protect the battery and control the charging speed and voltage. However, during the use of the solar controller, the internal components will generate a lot of heat, which is difficult to discharge, causing the temperature inside the solar charge controller to rise immediately, resulting in abnormal operation of the internal components.

[0003] In order to solve the above problems, a Chinese patent (publication number: CN212627236U) discloses a portable solar charging controller, including a controller housing, a display screen is set at one end of the controller housing, an indicator light is set at one end of the controller housing, a control button is set at one end of the controller housing, a square hole is opened at the other end of the controller housing, a fixed edge is set inside the controller housing, the lower end of the fixed edge is fixedly connected to a heat dissipation component, the lower end of the heat dissipation component is fixedly connected to a micro fan, a heat dissipation top plate is set at the upper end of the heat dissipation component, and the upper end of the heat dissipation top plate is fixedly connected to a circuit board.

[0004] The above scheme controls the opening and closing of the micro fan by temperature, and finally dissipates heat through the heat dissipation component, namely the aluminum sheet, with a high degree of automation; however, after a period of use, the heat dissipation component accumulates dust, which may reduce its heat dissipation efficiency, and the above scheme does not have a structure for cleaning the heat sink. If it cannot be cleaned regularly, it will still cause abnormal operation of internal components. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a controller that is easy to clean, including:

[0024] A controller body 1, wherein four sides of the bottom of the controller body 1 are provided with support feet 2;

[0025] A heat dissipation component, the heat dissipation component includes a heat sink 3 arranged at the bottom of the controller body 1;

[0026] The dust cleaning component includes a brush 16 disposed below the heat sink 3 and matched with the heat sink 3 , and the brush 16 is connected to a driving component to enable it to move back and forth along the length direction of the heat sink 3 .

[0027] In the prior art, since there is no structure for cleaning the heat sink 3, dust accumulates on the heat sink after a period of use, which may reduce its heat dissipation efficiency and cause internal components to malfunction if they are not cleaned regularly.

[0028] In order to solve the above problems, a dust cleaning component is provided in this embodiment.

[0029] Specifically, the detailed working process of this embodiment is as follows:

[0030] First, the support feet 2 are used to support the controller body 1 and ensure that the controller body 1 has a certain heat dissipation space.

[0031] When cleaning, the driving assembly is started, and the brush 16 starts to move from one side of the heat sink 3 and abuts against the heat sink 3 to clean, thereby sweeping away the dust adhering to the heat sink 3.

[0032] The driving assembly is started to reverse, and the brush 16 moves in the opposite direction, and the brush 16 returns to the previous position from the other side of the heat sink 3. This operation is repeated to achieve the reciprocating movement of the brush 16.

[0033] Further, the driving assembly comprises:

[0034] A support rod 17, wherein the support rod 17 is installed between two support legs 2 on the same side;

[0035] The screw rod 4 is arranged on the support rod 17 for transverse rotation and is located below the heat sink 3 ; wherein a micro motor 7 is arranged at one end of the screw rod 4 .

[0036] A limiting rod 5, wherein the limiting rod 5 is fixedly connected to the support rod 17;

[0037] The moving block 6 is threadably connected to the screw rod 4 and is slidably connected to the limiting rod 5 , and the top of the moving block 6 is connected to the brush 16 .

[0038] Specifically, in this embodiment, two support rods 17 may be provided, and the two support rods 17 are used to support the screw rod 4 and the limit rod 5 to ensure the normal operation of the drive assembly. The working process of the drive assembly is:

[0039] Start the micro motor 7, which drives the screw 4 to rotate. The screw 4 is threadably connected to the moving block 6, and the moving block 6 is slidably sleeved on the limit rod 5 so that the limit rod 5 restricts the rotation of the moving block 6 to a certain extent. Therefore, the moving block 6 moves along the length direction of the screw 4. The moving block 6 moves to drive the brush 16 to clean the heat sink 3.

[0040] The micro motor 7 is started to reverse, and the micro motor 7 drives the screw rod 4 to rotate in the opposite direction. The screw rod 4 is threadedly connected to the moving block 6, and the moving block 6 is slidably sleeved on the limit rod 5 so that the limit rod 5 restricts the rotation of the moving block 6 to a certain extent. Therefore, the moving block 6 moves in the opposite direction along the length direction of the screw rod 4, and the moving block 6 moves to drive the brush 16 to clean the heat sink 3 again. The repeated operation of the two forms can realize the repeated movement of the moving block 6 and the brush 16.

[0041] In order to ensure the cleaning efficiency, Figure 3 As shown, the brush 16 is provided with a plurality of burrs 8, and the burrs 8 can effectively clean the side of the heat sink 3, making the cleaning more uniform.

[0042] like Figure 1 and Figure 4 As shown, in order to ensure the normal connection between the wires and the controller and avoid clutter caused by too many wires, the utility model also proposes another embodiment. The main difference between this embodiment and the above embodiment is that a wiring head 9 is connected to one side of the controller body 1, and a wire management component for limiting the position of the wires is provided under the wiring head 9.

[0043] Specifically, the wires pass through the wire management assembly and are then connected to the wiring head 9 on the controller to ensure orderly connection of the wires, thereby facilitating subsequent plugging and unplugging operations of the wires.

[0044] Furthermore, the cable management component includes:

[0045] A fixing rod 10, wherein the fixing rod 10 is installed on one side of the controller body 1 and is located below the wiring head 9;

[0046] The limiting component group includes two clamping plates 11 , and the two clamping plates 11 are connected with an adjustment component to enable them to move or fix on the fixing rod 10 .

[0047] Specifically, in this embodiment, the electric wire is limited by two clamping pieces 11 . The two clamping pieces 11 are symmetrically arranged and cooperate to form an open-type limiting ring to better fit the electric wire.

[0048] In addition, the distance between the two clamping plates 11 can be freely adjusted by the adjustment component to accommodate wires of different sizes.

[0049] Further, the adjustment component comprises:

[0050] A sliding block 12, the top of which is correspondingly connected to the clamping piece 11 and is provided with a through hole for the fixing rod 10 to pass through;

[0051] The U-shaped rod 14 is slidably arranged in the through hole along a direction perpendicular to the length of the fixed rod 10 and forms an adjustable frame with the inner wall of the through hole. The fixed rod 10 passes through the adjustable frame and an adjustment spring 15 is arranged between the U-shaped rod 14 and the through hole. One end of the U-shaped rod 14 extends out of the through hole and is connected to the adjustment button 13.

[0052] Specifically, the working process of the adjustment component in this embodiment is as follows:

[0053] First, the sliding block 12 is sleeved on the fixing rod 10 through the through hole, and the fixing rod 10 passes through the adjustable frame.

[0054] Generally, the adjustment spring 15 is in a compressed state, so the spring exerts a certain pressure on the U-shaped rod 14 . At this time, the adjustable frame area is the smallest and exerts a certain pressure on the fixed rod 10 , so the sliding block 12 is in a limited state on the fixed rod 10 .

[0055] When adjusting the sliding, the adjusting button 13 is pressed, and the adjusting button 13 drives the U-shaped rod 14 to slide and compress the adjusting spring 15. At this time, the adjustable frame area is increased and the fixed rod 10 is not squeezed, so the sliding block 12 can be manually driven to move on the fixed rod 10 for adjustment. Then the sliding block 12 drives the corresponding clamping piece 11 to move to ensure the normal operation of the cable management assembly.

[0056] The specific working process of the utility model is:

[0057] First, the support feet 2 are used to support the controller body 1 and ensure that the controller body 1 has a certain heat dissipation space.

[0058] When cleaning, start the micro motor 7, which drives the screw rod 4 to rotate. The screw rod 4 is threadedly connected to the moving block 6, and the moving block 6 is slidably sleeved on the limit rod 5 so that the limit rod 5 restricts the rotation of the moving block 6 to a certain extent. Therefore, the moving block 6 moves to the right along the length direction of the screw rod 4, and the moving block 6 moves to drive the brush 16 to clean the heat sink 3.

[0059] The micro motor 7 is started to reverse, and the micro motor 7 drives the screw rod 4 to rotate in the opposite direction. The screw rod 4 is threadedly connected to the moving block 6, and the moving block 6 is slidably sleeved on the limit rod 5 so that the limit rod 5 restricts the rotation of the moving block 6 to a certain extent. Therefore, the moving block 6 moves to the left along the length direction of the screw rod 4, and the moving block 6 moves to drive the brush 16 to clean the heat sink 3 again. The repeated operation of the two forms can realize the repeated movement of the moving block 6 and the brush 16.

[0060] When in use, the adjustment button 13 is pressed, and the adjustment button 13 drives the U-shaped rod 14 to slide and compress the adjustment spring 15. At this time, the space inside the U-shaped rod 14 is increased and the fixed rod 10 is not squeezed, so the sliding block 12 can be manually driven to move on the fixed rod 10 for adjustment. The sliding block 12 is connected to the corresponding clamping piece 11 to adjust the distance between the two clamping pieces 11 to facilitate the placement of the wires.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
