Description

Technical Field

[0001] This application belongs to the field of vehicle wireless charging technology, and specifically relates to a wireless charger. Background Technology

[0002] Smart parking refers to the integrated application of wireless communication technology, mobile terminal technology, GPS positioning technology, and GIS technology to the collection, management, query, reservation, and navigation services of urban parking spaces. This achieves real-time updates, queries, reservations, and navigation services for parking space resources, maximizing the utilization rate of parking space resources, maximizing parking lot profits, and optimizing parking services for car owners.

[0003] The smart parking spaces are equipped with wireless chargers. Since the transmission efficiency and power of wireless charging are greatly affected by the transmission distance, the wireless chargers are equipped with lifting mechanisms to facilitate vehicle charging.

[0004] In related technologies, the lifting mechanism of a wireless charger is exposed on its sides after it rises, resulting in poor waterproofing and easy corrosion of parts. Summary of the Invention

[0005] To address the technical problem of component corrosion in the lifting mechanism of current wireless chargers, this application provides a wireless charger.

[0006] This application provides a wireless charger, comprising:

[0007] The base has a first mounting portion and a second mounting portion arranged sequentially along a first direction;

[0008] First top cover;

[0009] An elastic cylinder, the lower end of which is connected to the first mounting part and the upper end of which is connected to the first upper cover, the elastic cylinder, the first upper cover and the first mounting part together form a first receiving cavity for accommodating the charging module and the lifting mechanism, the charging module being connected to the first upper cover and the driving end of the lifting mechanism.

[0010] The second upper cover has ventilation holes and is connected to the second mounting part. The second upper cover and the second mounting part together form a second receiving cavity for accommodating the control module and the heat dissipation module.

[0011] The base is provided with a connecting channel that connects the first receiving cavity and the second receiving cavity.

[0012] In some embodiments, the base includes a partition connected to the second mounting portion, the partition being located within the second receiving cavity to divide the second receiving cavity into a control cavity for receiving the control module and a heat dissipation cavity for receiving the heat dissipation module; the communication channel connects the control cavity and the first receiving cavity, and the wireless charger further includes a vent valve mounted on the partition, the vent valve connecting the control cavity and the heat dissipation cavity.

[0013] In some embodiments, the vent valve and the connecting channel are offset from the control module along the second direction, which is perpendicular to the first direction.

[0014] In some embodiments, the second mounting portion includes a first base segment and a second base segment, the first mounting portion, the first base segment and the second base segment are arranged sequentially along the first direction, and along the second direction, the size of the first base segment is larger than the size of the second base segment, and the vent valve is installed at one end of the first base segment along the second direction.

[0015] In some embodiments, both ends of the first base segment extend out of the second base segment along the second direction, and the portions of the first base segment extending out of the second base segment along the second direction are provided with the vent valve.

[0016] In some embodiments, the vent valve includes a valve body and a valve cover, the valve body having a through hole, and the valve cover being movably connected to the valve body to allow the through hole to be open or closed.

[0017] In some embodiments, the vent valve further includes a first drive member and a threaded rod, the first drive member being throttledly connected to the threaded rod, the valve cover having a threaded hole, and the end of the threaded rod extending into the threaded hole to move the valve cover away from or against the valve body;

[0018] The wireless charger also includes a first pressure sensor for detecting the air pressure in the heat dissipation cavity and a second pressure sensor for detecting the air pressure in the control cavity. The first driving component, the first air pressure sensor, and the second pressure sensor are all electrically connected to the control module.

[0019] In some embodiments, multiple connecting channels are provided, and the multiple connecting channels are arranged sequentially along the second direction.

[0020] In some embodiments, the base includes a body and a connecting pipe, the connecting pipe being connected to the first receiving cavity and the second receiving cavity, the lumen of the connecting pipe forming the connecting channel.

[0021] In some embodiments, the first top cover is provided with a receiving groove, the upper end of the elastic cylinder extends into the receiving groove and is connected to the groove wall of the first top cover; the lifting mechanism is a scissor lift mechanism; and the elastic cylinder is an accordion cover.

[0022] According to the wireless charger provided in the embodiments of this application, since the first mounting part of the base and the first top cover are connected by an elastic cylinder, the height of the first accommodating cavity formed by the elastic cylinder, the first mounting part and the first top cover is adjustable. The driving end of the lifting mechanism, the charging module and the first top cover are connected in sequence. With this configuration, during the lifting process of the driving end of the lifting mechanism, the height of the charging module and the first top cover are adjustable, thereby making the height of the wireless charger adjustable. Therefore, the vehicle can enter or leave the smart parking space when the height of the wireless charger can be adjusted to the lowest level.

[0023] Regardless of whether the lifting mechanism is raised or lowered, it remains within the first receiving cavity enclosed by the elastic cylinder, the first mounting part, and the first upper cover, and is not exposed to the outside world. Therefore, it has good waterproof performance and is not easily corroded, thereby improving the service life of the lifting mechanism.

[0024] Because the size of the first receiving cavity changes during the lifting process of the lifting mechanism in this application, and the air pressure is unbalanced with the outside air pressure, the lifting mechanism is easily obstructed from rising or falling. A connecting channel is provided to connect the first receiving cavity and the second receiving cavity, and a ventilation hole is provided on the second upper cover. This allows the first receiving cavity to connect with the outside air pressure in sequence through the connecting channel, the second receiving cavity and the ventilation hole, thereby balancing the air pressure inside the first receiving cavity with the outside air pressure, and thus realizing the smooth lifting of the lifting mechanism.

Detailed Implementation

[0037] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] This application provides a wireless charger that can ensure the waterproof performance of the lifting mechanism and improve the smoothness of the lifting mechanism's movement.

[0039] This application is described below with reference to the accompanying drawings and specific embodiments:

[0040] Please see Figure 1 as well as Figure 4The wireless charger 100 provided in this application embodiment includes a base 110, an elastic cylinder 120, a first upper cover 150, a second upper cover 180, a charging module 140, a lifting mechanism 130, a control module 160, and a heat dissipation module 170. Wherein:

[0041] The base 110 is the main mounting base for the wireless charger 100. It is typically placed on the ground or partially embedded in the ground. The base 110 has a first mounting portion 111 and a second mounting portion 112 arranged sequentially along a first direction. The lower end of the elastic cylinder 120 is connected to the first mounting portion 111, and the upper end is connected to the first upper cover 150. This arrangement, with the elastic cylinder 120, the first mounting portion 111, and the first upper cover 150 together, forms a height-adjustable first receiving cavity 101. The charging module 140 and the lifting mechanism 130 are housed within the first receiving cavity 101, providing waterproof and dustproof protection. This also prevents the charging module 140 and the lifting mechanism 130 from rusting or becoming contaminated, thus extending their service life. The charging module 140 is connected to the drive end of the first upper cover 150 and the lifting mechanism 130, allowing the lifting mechanism 130 to raise and lower the charging module 140 and the first upper cover 150 to adjust the height of the charging module 140 and thus the charging transmission distance, adapting to vehicles of different heights.

[0042] The second upper cover 180 is connected to the second mounting part 112. The second upper cover 180 and the second mounting part 112 together form a second receiving cavity. The control module 160 and the heat dissipation module 170 are both disposed in the second receiving cavity to protect the control module 160 and the heat dissipation module 170. The heat dissipation module 170 can cool and dissipate heat from the control module 160, so that the control module 160 can operate smoothly. The second upper cover 180 is provided with a ventilation hole 181, so that the airflow carrying heat can be discharged through the ventilation hole 181 to dissipate heat from the control module 160.

[0043] During the descent of the lifting mechanism 130, the volume of the first receiving cavity 101 decreases, and the air inside cannot be expelled, hindering the descent of the lifting mechanism 130. This causes the charging module 140 to fail to retract. Please refer to [link / reference needed]. Figure 6Because the base 110 is provided with a connecting channel 114 connecting the first receiving cavity 101 and the second receiving cavity, during the descent of the lifting mechanism 130, the gas in the first receiving cavity 101 can flow into the second receiving cavity through the connecting channel 114. Since the second upper cover 180 is provided with a ventilation hole 181, the airflow can continue to flow to the outside through the ventilation hole 181, thereby reducing the air pressure in the first receiving cavity 101, allowing the lifting mechanism 130 to descend smoothly and the charging module 140 to retract. Similarly, during the ascent of the lifting mechanism 130, the volume of the first receiving cavity 101 increases, and since the outside air pressure is greater than the gas pressure inside the first receiving cavity 101, outside gas can flow into the first receiving cavity 101 sequentially through the ventilation hole 181, the second receiving cavity, and the connecting channel 114, balancing the air pressure between the first receiving cavity 101 and the outside, allowing the lifting mechanism 130 to rise smoothly.

[0044] The first direction and the second direction mentioned in this application are perpendicular to each other. For example, the first direction is along the north-south direction and the second direction is along the east-west direction, or the first direction is along the east-west direction and the second direction is along the north-south direction.

[0045] The base 110 serves as the mounting foundation; in some embodiments, please refer to [reference needed]. Figure 6 The base 110 includes a body and a connecting pipe 115. The body includes a first mounting portion 111 and a second mounting portion 112. The connecting pipe 115 connects the first receiving cavity 101 and the second receiving cavity. The lumen of the connecting pipe 115 forms a connecting channel 114 to facilitate gas flow between the first receiving cavity 101 and the second receiving cavity. In some embodiments, a channel can also be formed on the body as the connecting channel 114, which also allows gas flow between the first receiving cavity 101 and the second receiving cavity.

[0046] In some embodiments, please continue reading Figure 6 Multiple connecting channels 114 are provided, and these channels 114 are arranged sequentially along the second direction. This increases the airflow area and ensures the efficiency of balancing the first receiving cavity 101 with the external air pressure. In some embodiments, two connecting channels 114 can be provided, and they are staggered from the control module 160 along the second direction. In specific implementations, one connecting channel 114 can be provided on each side of the control module 160 along the second direction, or two connecting channels 114 can be provided on one side of the control module 160 along the second direction. This application does not impose any restrictions.

[0047] In some embodiments, please refer to Figure 4The base 110 includes a partition 113 mounted on the second mounting portion 112. The partition 113 is located within the second receiving cavity, dividing the second receiving cavity into a control cavity 102 for accommodating the control module 160 and a heat dissipation cavity 103 for accommodating the heat dissipation module 170. This arrangement places the control module 160 below and the heat dissipation module 170 above. The control module 160 is positioned below and is close in height to the first drive member 193 of the lifting mechanism 130, facilitating electrical connection between the control module 160 and the first drive member 193 of the vent valve 190. Water may enter the heat dissipation cavity 103 through the vent 181. Separating the control cavity 102 and the heat dissipation cavity 103 reduces the risk of water contact between the control cavity 102 and the heat dissipation cavity 103. In this configuration, the connecting channel 114 connects the control cavity 102 and the first receiving cavity 101. The wireless charger 100 also includes a vent valve 190 installed on the partition 113. The vent valve 190 connects the control cavity 102 and the heat dissipation cavity 103. Thus, during the descent of the lifting mechanism 130, the air in the first receiving cavity 101 flows sequentially through the connecting channel 114, the control cavity 102, the vent valve 190, the heat dissipation cavity 103, and the vent hole to reach the outside. During the ascent of the lifting mechanism 130, the outside air flows sequentially through the vent hole, the heat dissipation cavity 103, the vent valve 190, the control cavity 102, and the connecting channel 114 to reach the first receiving cavity 101, thereby achieving air pressure balance between the first receiving cavity and the outside, and enabling the lifting mechanism 130 to rise and fall smoothly.

[0048] In some embodiments, please refer to Figure 6 Along the second direction, the vent valve 190 and the control module 160 are offset from each other, and the connecting channel 114 is also offset from the control module 160. This allows for smooth airflow and improves the efficiency of balancing the first receiving cavity 101 with the external air pressure. In other embodiments, along the second direction, the connecting channel 114 may also partially correspond to the control module 160, so that the airflow flowing through the connecting channel 114 can be used to cool the control module 160.

[0049] In some embodiments, please refer to Figure 3 The second mounting part 112 includes a first base section 1121 and a second base section 1122. The first mounting part 111, the first base section 1121 and the second base section 1122 are arranged sequentially along a first direction. Along a second direction, the size of the first base section 1121 is larger than the size of the second base section 1122. The vent valve 190 is located at one end of the first base section 1121 along the second direction.

[0050] Along the second direction, the size of the first base segment 1121 is larger than the size of the second base segment 1122. The size of the second base segment 1122 is smaller, which can accommodate the control module 160, saving space. The size of the first base segment 1121 is larger, which can not only accommodate the control module 160, but also provide a place for the vent valve 190, thus realizing the arrangement of the vent valve 190 and the control module 160.

[0051] The size of the lifting mechanism 130 along the second direction is larger than the size of the control module 160. Along the second direction, the size of the first mounting part 111 is larger than the size of the second base section 1122. The size of the first base section 1121 and the first mounting part 111 along the second direction can be the same. Both of them are flush at both ends along the second direction, reducing corner structures and reducing the manufacturing difficulty of the base 110.

[0052] In some embodiments, both ends of the first base segment 1121 extend out of the second base segment 1122 along the second direction, and each end of the first base segment 1121 extending out of the second base segment 1122 along the second direction is provided with a vent valve 190. Providing two vent valves 190 increases the airflow and ensures efficient balance between the first receiving cavity 101 and the external air pressure.

[0053] In some embodiments, please refer to Figure 8 The vent valve 190 includes a valve body 191 and a valve cover 192. The valve body 191 has a through hole, and the valve cover 192 is movably connected to the valve body 191 to allow the through hole to be open or closed. When the air pressure difference between the control chamber 102 and the heat dissipation chamber 103 is not lower than a set value, the through hole is open; when the air pressure difference between the control chamber 102 and the heat dissipation chamber 103 is lower than the set value, the through hole is closed.

[0054] In some embodiments, please refer to Figure 8 as well as Figure 9 The vent valve 190 also includes a first driving member 193 and a threaded rod 194. The first driving member 193 is pulsatorically connected to the threaded rod 194. The valve cover 192 is provided with a threaded hole, and the end of the threaded rod 194 extends into the threaded hole so that the valve cover 192 is away from or against the end of the valve body 191. To prevent the valve cover 192 from rotating during its axial reciprocating movement along the through hole, a protrusion is provided on the lower side of the valve cover 192, and the valve body 191 is provided with a sliding groove extending axially along the through hole, in which the protrusion is slidably disposed. Of course, this is just an example; there are many ways in the prior art to achieve the reciprocating movement of the valve cover 192 along the height direction without rotation, which will not be elaborated here.

[0055] The wireless charger 100 also includes a first pressure sensor for detecting the air pressure in the heat dissipation cavity 103 and a second pressure sensor (not shown) for detecting the air pressure in the control cavity 102. The first drive unit 193, the first air pressure sensor, and the second pressure sensor are all electrically connected to the control module 160. The control module 160 calculates the difference between the pressure signals sent by the first and second pressure sensors and compares the difference with a set value. If the difference is not lower than the set value, the control module 160 controls the first drive unit 193 to open the valve cover 192. If the difference is lower than the set value, the control module 160 controls the first drive unit 193 to reverse its action to close the valve cover 192.

[0056] The elastic cylinder 120 serves as a seal and adapts to the lifting mechanism 130. In some embodiments, the elastic cylinder 120 can be cylindrical, cuboid, or prismatic in shape, without specific limitations. In some embodiments, the elastic cylinder 120 can be a bellows cover, also known as a bellows-style protective cover, which can rise and fall with the lifting mechanism 130, providing good sealing and a long service life. In other embodiments, the elastic cylinder 120 can also be a bellows, which can also extend and retract with the lifting mechanism 130, providing good sealing.

[0057] In some embodiments, please refer to Figure 1 The first upper cover 150 is provided with a receiving groove. The upper end of the elastic cylinder 120 extends into the receiving groove and is connected to the groove wall of the upper cover, forming a structure in which the first upper cover 150 is on the outside and the elastic cylinder 120 is inside, which further improves the sealing performance of the first receiving cavity 101.

[0058] In some embodiments, please refer to Figure 10 The elastic cylinder 120 and the first upper cover 150 can be connected by a screw 123. The shank of the screw 123 extends into the groove wall of the first upper cover 150, and the head of the screw is located inside the elastic cylinder 120. The outer side of the first upper cover 150 has no gaps, resulting in good waterproof performance. To further improve the sealing performance between the elastic cylinder 120 and the first upper cover 150, a sealing strip 121 can be provided between the elastic cylinder 120 and the first upper cover 150, and a pressure strip 122 can be provided between the head of the elastic cylinder 120 and the head of the screw 123.

[0059] In some embodiments, please refer to Figure 1 The first upper cover 150 may include a cover plate 151 and a connecting ring 152. The cover plate 151 and the connecting ring 152 are connected, and the cover plate 151 and the connecting ring 152 together form a receiving groove. The elastic cylinder 120 is connected to the connecting ring 152 by screws 123. The first upper cover 150 is set as a split structure to facilitate the connection between the elastic cylinder 120 and the connecting ring 152. The cover plate 151 and the connecting ring 152 can be snapped together.

[0060] The lifting mechanism 130 can be a scissor lift 134 or a lead screw 132 assembly, etc.

[0061] In some embodiments, the lifting mechanism 130 includes a second drive member 131, a lead screw, a push rod 133, a scissor fork 134, a slide rail 135, and a lifting plate 136. The second drive member 131 is drivenly connected to the lead screw. The lower end of the push rod 133 is threaded to the lead screw, and the upper end is hinged to the fork arm of the scissor fork 134. The lower end of the fork arm is hinged to the first mounting part 111, and the upper end is slidably connected to the slide rail 135. The slide rail 135 is connected to the lifting plate 136. The control module 160 is installed between the lifting plate 136 and the first upper cover 150. The second drive member 131 is electrically connected to the control module 160.

[0062] The second driving component 131, for example, rotates a motor, which drives the lead screw to rotate, thereby causing the push rod 133 to move along the extension direction of the lead screw, causing the fork arm to rotate around its lower end and move its upper end along the slide rail 135, thereby lifting the slide rail 135 and the lifting plate 136, thus realizing the lifting and lowering of the charging module 140.

[0063] The edge of the second upper cover 180 extends downward to form a groove. Ventilation holes 181 are located on the edge of the second upper cover 180. Multiple ventilation holes 181 can be provided, and multiple ventilation holes 181 are spaced apart to improve ventilation.

[0064] The heat dissipation module 170 is a heat dissipation structure and can be a cooling fan. The fan rotates to dissipate heat from the control module 160. The charging module can charge the vehicle, and it is existing technology. For more details, please refer to the existing technology disclosures. This application will not elaborate further.
