Because the controller body will produce a large amount of heat in the running process, if the heat produced can not be effectively dissipated, time long can cause damage to internal circuit, not only can reduce its service life, but also can lead to the operation safety of large -scale equipment such as crane.

[0003] The Chinese patent with the publication number CN117896958A discloses a kind of intelligent non -contact controller of long service life, including shell, with the first protective plate of shell interior fixed connection and the second protective plate of fixed connection in the first protective plate both sides, still include: motor bracket, the motor bracket is fixedly installed in the interior of shell, drive mechanism is equipped on the motor bracket;First heat dissipation mechanism, the first heat dissipation mechanism is installed in one side of first protective plate.

[0004] The above-mentioned patent realizes the heat dissipation of non -contact controller by setting heat dissipation mechanism in the interior of shell. Because the working condition environment of non -contact controller is relatively bad, dust particles in the external environment are sucked into and attached to heat dissipation mechanism in the process of working, and then the working efficiency of heat dissipation mechanism is affected. Therefore, dust and dirt adhered to heat dissipation mechanism need to be cleaned regularly, and a large amount of dust spilled outward in the cleaning process is easily attached to electrical components near heat dissipation mechanism, and then secondary pollution is caused, thereby affecting the working state of electrical components and reducing the service life of non -contact controller.

[0007] By adopting the technical scheme, when the mounting frame is located at the first position, the heat dissipation fan corresponds to the heat dissipation channel, and the heat dissipation fan is matched with the heat dissipation channel to conduct the airflow in the external space into the inner cavity to dissipate heat for the circuit control board. When dust on the heat dissipation fan needs to be cleaned, the mounting frame is switched from the first position to the second position by the control member, so that the heat dissipation fan is separated from the heat dissipation channel and the isolation feature blocks the heat dissipation channel, thereby avoiding that dust overflowing from the heat dissipation fan in the cleaning process enters the inner cavity through the heat dissipation channel and adheres to the circuit control board, thereby avoiding secondary pollution and prolonging the service life of the non-contact controller.

[0008] Further, the mounting frame is slidingly arranged in the housing and the movement path intersects the heat dissipation channel, and when the mounting frame is located at the second position, the heat dissipation fan is located outside the housing.

[0009] By adopting the technical scheme, the heat dissipation fan moving with the mounting frame can enter the heat dissipation channel and leave the heat dissipation channel outside the housing, so that the heat dissipation fan can be conveniently cleaned.

[0011] By adopting the technical scheme, the partition plate located in the inner cavity is designed, so that the existing partition plate does not increase the additional volume of the product and does not affect the external appearance of the product, and the partition plate can also be protected.

[0012] Further, the control member includes a lever slidingly matched with the outer wall of the housing and moving with the mounting frame, and a positioning assembly formed between the lever and the housing, and when the positioning assembly is in the positioning state, the mounting frame is located at the first position.

[0013] By adopting the technical scheme, the lever is actuated to drive the mounting frame to switch between the first position and the second position, and the positioning assembly is arranged to position the mounting frame at the first position, so as to ensure the structural stability in the working state.

[0014] Further, the positioning assembly includes a fixed claw fixedly arranged on the outer wall of the housing and a movable claw moving with the lever and capable of being clamped with the fixed claw, the movement path of the movable claw intersects the fixed claw, and the movable claw is made of elastic material.

[0015] By adopting the technical scheme, the movable claw is clamped with the fixed claw to position the mounting frame.

[0016] The mounting frame is further configured such that it has a slot with an opening at one end, and the cooling fan is plugged into the slot. When the mounting frame is in the first position, the mounting frame, together with the housing, is used to restrict the cooling fan from leaving the slot.

[0017] By adopting the above technical solution, this structure ensures the stable installation of the cooling fan during operation while allowing for easy disassembly and assembly.

[0018] In summary, this utility model has the following beneficial effects: it can avoid secondary pollution caused during the cleaning of the fan, thereby extending the service life of the contactless controller. Attached Figure Description
