Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging piles, and in particular to a dust-proof and heat-dissipating charging pile. Background Art

[0002] To meet the requirements of environmental protection and energy conservation, various types of electric vehicles have been launched on the market, such as battery electric vehicles, battery vehicles, scooters, battery vehicles, and single-wheel electric vehicles. As a result, the demand for charging electric vehicles at various locations has increased dramatically. Against this background, charging piles have emerged.

[0003] With the widespread use of new energy vehicles, charging equipment for new energy vehicles is becoming increasingly popular. Unlike traditional cars, new energy vehicles cannot be put into use immediately after refueling. The charging process of new energy vehicles can take several hours. In order to provide new energy vehicles with convenient charging services, a large number of charging piles need to be deployed on the roadside.

[0004] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0005] In the prior art, there is a Chinese patent with the authorization announcement number CN218400271U, entitled "A Dust-proof and Heat-dissipating Charging Pile". The patent discloses a dust-proof and heat-dissipating charging pile, comprising a charging pile body, a dust-proof and heat-dissipating device provided on the side of the charging pile, a charging seat placement chamber provided inside the charging pile body, and an auxiliary device provided on the front of the charging pile body. The dust-proof and heat-dissipating device comprises a dust-proof net, a fan housing, an air outlet duct, a connecting rod, a dust collecting disc, a limit frame, a dust collecting plate, and a placement bracket. In the patent, by providing a dust-proof and heat-dissipating device, dust can be collected and easily removed for processing. Dust-proof components can be provided at the heat dissipation position, so that the sucked dust will not directly drift to the outside world and affect the environment. The effect during use is good, and the position of the fan will not change and multiple fans are provided.

[0006] Another example is the Chinese patent with the authorization announcement number CN212400946U, entitled A Dust-proof and Heat-dissipating Charging Pile. The above patent discloses a dust-proof and heat-dissipating charging pile, including a charging pile body and a heat dissipation mechanism. The heat dissipation mechanism includes a heat dissipation cavity provided in the charging pile body, an air outlet provided on the side wall of the charging pile body, an air inlet provided on the side wall of the charging pile body, an exhaust device, a filtering device and a dust collecting device coordinated with the air outlet, the air outlet and the air inlet are both connected to the heat dissipation cavity, the filtering device includes a partition provided in the heat dissipation cavity, a filter plate provided on the partition, a dust-proof cloth coordinated with the filter plate and a connecting component connecting the filter plate and the partition, and a plurality of filter holes are provided on the filter plate.

[0007] In the prior art, such as the above-mentioned patent, when in use, the driving motor drives the heat dissipation fan blades to rotate, the upper heat dissipation fan blades draw the external air into the charging pile body, and the lower heat dissipation fan blades discharge the air inside the charging pile, thereby dissipating the heat inside the charging pile under the rapid circulation of air, and dissipating the heat of the charging pile. In the heat dissipation process, under the action of the dustproof net, it can effectively block the external dust and impurities from entering the charging pile, and prevent the dust and impurities from accumulating too much in the charging pile. However, it is known that under the blocking effect of the dustproof net, a large amount of dust and impurities will be blocked by the dustproof net on the outside of the charging pile, but at this time, the dust and impurities will accumulate on the outside of the dustproof net, and may even block the air duct of the ventilation hole, so that the air circulation inside the charging pile is not smooth, affecting the internal heat dissipation of the charging pile, and there are certain deficiencies. Summary of the Invention

[0008] The purpose of the present invention is to provide a dust-proof and heat-dissipating charging pile to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a dust-proof and heat-dissipating charging pile, comprising a cabinet and a plurality of supporting units installed on the cabinet, a plurality of ventilation holes being provided on the side walls of the cabinet, an inner ventilation slot being provided on the cabinet, and an extension frame being fixedly connected to the solid body, an outer ventilation slot being provided on the extension frame, and a filter unit being provided on both the inner ventilation slot and the outer ventilation slot; a cleaning mechanism being slidably connected to the interior of the extension frame, and a power mechanism for driving the cleaning mechanism to slide being provided inside the cabinet; a heat dissipation mechanism being provided inside the cabinet, and the heat dissipation mechanism and the cleaning mechanism being connected via a switching mechanism; a temperature sensing component being also provided inside the cabinet, and the temperature sensing component being electrically connected to the switching mechanism.

[0010] Furthermore, the heat dissipation mechanism includes an exhaust fan installed inside the cabinet, the exhaust fan is installed on the cabinet through a mounting frame, and a servo motor is provided inside the cabinet, and the servo motor drives the exhaust fan to rotate through a power shaft.

[0011] Furthermore, the cleaning mechanism includes a cleaning plate slidably connected to the inside of the extension frame, and cleaning brushes are slidably connected on both sides of the cleaning plate. Multiple sets of mounting springs are also arranged between the cleaning brushes and the cleaning plate. The elastic force of the multiple mounting springs drives the cleaning brushes to abut against the outer ventilation groove and the inner ventilation groove respectively.

[0012] Furthermore, the switching mechanism includes a support unit slidably connected to the cabinet body, a switching rod is rotatably connected to the support unit, and the switching rod is rotatably connected to the power shaft through a limit unit; and a positioning frame is provided on the cabinet body, and a cylinder is installed on the positioning frame for driving the positioning frame to slide inside the cabinet body.

[0013] Furthermore, the limiting unit includes a plurality of limiting blocks fixedly connected to the switching rod, a limiting groove adapted to the limiting block is opened inside the power shaft, and the limiting block is slidingly connected to the limiting groove; an avoidance groove is also opened on the power shaft, and a plurality of limiting grooves are connected to the avoidance groove; a connecting spring is also arranged between the switching rod and the power shaft.

[0014] Furthermore, the support unit includes a mounting plate, positioning rods are fixedly connected to both sides of the mounting plate, connecting plates are fixedly connected to the two positioning rods, and the switching rod is rotatably connected to the connecting plates.

[0015] Furthermore, the power mechanism includes a reciprocating screw rod rotatably connected to the extension frame, and extension blocks are fixedly connected on both sides of the cleaning plate, and the reciprocating screw rod is threadedly connected to the extension block; and the two reciprocating screw rods are connected by a first synchronization unit; the switching rod and the first synchronization unit are connected by a transmission unit.

[0016] Furthermore, the transmission unit includes a linkage rod rotatably connected to the extension frame, and the linkage rod is transmission-connected to the switch rod via a second synchronization unit.

[0017] Furthermore, the carrying unit includes a carrying frame installed on the cabinet, and the carrying frame is provided with a mounting slot adapted to the charging head.

[0018] Furthermore, a display screen is provided on the cabinet.

[0019] Compared with the existing technology, the beneficial effects of the present invention are as follows: the dust-proof and heat-dissipating charging pile is designed with internal ventilation slots and external ventilation slots on the cabinet, and both are provided with filter units. The double-layer ventilation slot design allows the external air to be initially filtered by the filter unit of the external ventilation slot before entering the interior of the charging pile, and then to be filtered twice by the filter unit of the internal ventilation slot. Compared with the existing technology that only has a single dust-proof component, the double-layer filter structure can more effectively block dust and impurities, greatly reducing the probability of dust entering the interior of the charging pile, and significantly improving the dust-proof effect; The setting of the cleaning mechanism further enhances the dustproof performance. The cleaning mechanism includes a cleaning plate that is slidably connected to the inside of the extension frame. The cleaning brushes on both sides of the cleaning plate abut against the ventilation slots, and elastic force is provided by installing springs to ensure that the cleaning brushes fit tightly with the ventilation slots. The power mechanism drives the cleaning mechanism to slide inside the extension frame, regularly clean the ventilation slots, and promptly remove dust attached to the filter unit to prevent excessive dust accumulation from clogging the ventilation holes. This automated cleaning mechanism not only prevents dust from entering the charging pile, but also ensures the unobstructed ventilation slots and maintains good heat dissipation performance. The heat dissipation mechanism includes an exhaust fan installed inside the cabinet. The exhaust fan is driven by a servo motor to rotate, which can quickly discharge the heat inside the charging pile. The temperature sensing component is electrically connected to the switching mechanism, which automatically adjusts the working state of the heat dissipation mechanism according to the actual temperature inside the charging pile. When the temperature sensing component detects that the internal temperature has risen, the switching mechanism will automatically start the heat dissipation mechanism, increase the speed of the exhaust fan, and quickly discharge the heat; when the temperature drops to a safe range, the switching mechanism will automatically adjust the speed of the exhaust fan or suspend the operation of the heat dissipation mechanism, avoiding unnecessary energy waste, while ensuring that the inside of the charging pile is always within the appropriate temperature range, extending the service life of the charging pile; The switching mechanism design allows for flexible switching between the cooling and cleaning mechanisms. The switching lever on the support unit is rotatably connected to the power shaft via a limiter. The cylinder on the positioning frame drives the positioning frame to slide within the cabinet, enabling seamless switching between the cooling and cleaning mechanisms. During the cooling process, the cleaning mechanism can temporarily stop to avoid interfering with the cooling airflow. When cooling demand is low, the cleaning mechanism can be activated to clean the ventilation slots, ensuring they remain well ventilated at all times, further improving cooling efficiency.
