[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please refer to Figures 1 to 3 This utility model is a rechargeable foot support, which includes a base assembly 1 and a support rod 2 connected to the base assembly 1.
[0026] Please refer to Figures 1 to 2 The base assembly 1 includes a housing 11 and a heat sink 12 that docks with the housing 11. The housing 11 is usually made of cast iron or stainless steel and includes a lower housing 111 and an upper housing 112. The shape of the lower housing 111 can be changed according to requirements. In this embodiment, the lower housing 111 is approximately capsule-shaped and has a cavity 113 inside. A charging coil 13 and a PCB circuit board 14 are installed in the cavity 113. The charging coil 13 is arranged at the bottom of the cavity 113 and the PCB circuit board 14 is located above the charging coil 13. Specifically, the PCB circuit board 14 is fixedly connected to the housing 11 by bolts or screws through it, so that the PCB circuit board 14 is fixedly installed in the cavity 113.
[0027] Both the charging coil 13 and the PCB circuit board 14 are existing technologies, so only a general explanation is given. The charging coil 13 is an inductor coil wound with copper wire, which is usually a planar spiral structure and generates an alternating magnetic field. The PCB circuit board 14 integrates control circuits, power electronic components and communication modules, which drive the charging coil 13 and manage energy transfer.
[0028] The lower housing 111 has an installation area 114 on its top, which is connected to the cavity 113 and is used to install the heat sink 12.
[0029] The upper housing 112 includes a connecting protrusion 115 and a fixing part 116. The bottom of the connecting protrusion 115 is fixedly connected to the upper surface of the lower housing 111, and its top extends obliquely. The fixing part 116 is fixedly connected to the connecting protrusion 115, with one end fixedly connected to the top of the connecting protrusion 115 and the other end extending above the mounting area 114. The fixing part 116 is fixedly connected to the heat sink 12 located on the mounting area 114 by bolts or screws.
[0030] Please refer to Figure 2 The heat sink 12 is made of heat-dissipating metal. In this embodiment, the heat sink 12 is made of aluminum. It includes a docking plate 121 and a docking block 122 fixedly connected to the docking plate 121. The docking plate 121 is recessed from the lower surface to form a receiving groove 123. The receiving groove 123 is used to receive the PCB circuit board 14. The shape of the docking plate 121 matches the shape of the mounting area 114 and is fastened to the mounting area 114. The docking block 122 is integrally formed with the docking plate 121. Its bottom is fixedly connected to the docking plate 121, and its top extends obliquely. Its oblique angle is the same as the oblique angle of the upper shell 112.
[0031] The opposite sides of the fixing part 116 and the docking block 122 are recessed from the surface to form a movable groove 15 and a receiving groove 16. The movable groove 15 is hemispherical. When the fixing part 116 and the docking block 122 are docked, the opposite movable groove 15 forms a sphere for connecting the support rod 2. The receiving groove 16 is rectangular and connects the cavity 113 and the movable groove 15. When the fixing part 116 and the docking block 122 are docked, they form a sealed cavity for accommodating wires (not shown). The wires connect the PCB circuit board 14 and the charging coil 13 to transmit high-frequency alternating current or induced current. The other end of the wire extends out of the base assembly 1 through the movable groove 15.
[0032] Please refer to Figure 3 The support rod 2 includes a universal ball 21, a rod body 22 connected to the universal ball 21, and a connecting part 23 located at the end of the rod body 22. The universal ball 21 is placed in the movable groove 15. One end of the rod body 22 is connected to the universal ball 21, and the other end is fixedly connected to the connecting part 23. The rod body 22 and its connecting part 23 can move around the universal ball 21. The connecting part 23 is used to connect with other areas, such as the vehicle body.
[0033] In manufacturing this rechargeable kickstand, the charging coil 13 and PCB circuit board 14 are installed in the cavity 113. The support rod 2 is placed between the outer shell 11 and the heat sink 12. The heat sink 12 is then fastened to the installation area 114. The fixing part 116 and the docking block 122 are docked. Bolts or screws pass through the fixing part 116 and the docking block 122, and the fixing part 116 and the docking block 122 are fixedly connected. The heat sink 12 is fixed on the installation area 114, and at the same time, a spherical movable groove 15 is formed. The movable groove 15 encloses the universal ball 21. The support rod 2 moves around the universal ball 21. The wire connects the PCB circuit board 14 and the charging coil 13. The other end extends out of the base assembly 1 through the receiving groove 16 and the movable groove 15 and connects to the vehicle battery.
[0034] When the rechargeable footrest of this utility model is in use, the base assembly contacts the wireless charging area, the PCB circuit board 14 drives the charging coil 13 and manages the energy transmission, and the wires transmit the generated current of the coil 13 to the vehicle battery.
[0035] This utility model is a rechargeable foot support, which is safe and has high charging efficiency. By opening an installation area in the outer shell, the installation area is connected to the cavity, and a heat sink is installed in the installation area. The heat inside the cavity is dissipated through the heat sink, avoiding problems such as short circuits caused by overheating of the PCB circuit board and charging coil, reducing the temperature inside the cavity and improving charging efficiency.
