Description
Technical Field
[0001] This utility model relates to the technical field of wireless charging receivers, specifically a vehicle-mounted receiver coil structure. Background Technology
[0002] The existing vehicle-end receiving coil structure includes a bottom coil coil structure and an upper water-cooling plate. The bottom plate of the water-cooling plate is recessed to form a water-cooling plate cavity. During actual assembly, the bottom plate of the water-cooling plate contacts the upper stop platform of the coil coil mechanism. When potting glue into the cavity of the coil coil structure, the glue easily overflows from the contact surface between the coil coil structure and the bottom plate of the water-cooling plate, making it difficult to clean the residual glue and causing poor appearance. In addition, the width of the wiring groove formed between the slots in the existing coil is narrow. It directly and rigidly holds the wire through the gap between the two sets of slots, making it difficult to place the wire and resulting in long assembly time and delaying the production schedule. Furthermore, the existing coil coil structure requires a large amount of glue to fill the cavity, resulting in a large weight of the entire structure and an increase in production costs. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a vehicle-end receiving coil disc structure, which effectively solves the problem of excess adhesive, making coil placement simple and reliable, and reducing adhesive usage and production costs.
[0004] A vehicle-end receiving coil disk structure, characterized in that it comprises:
[0005] A water-cooled base plate includes a first base plate and a surrounding ring plate. The outer periphery of the first base plate is provided with an upper recessed positioning groove corresponding to the position of the surrounding ring plate.
[0006] The coil body includes a second base plate, an outer ring plate, and an inner cavity. The outer ring plate has an upper convex retaining wall on its outer periphery. The outer ring plate, except for the upper surface of the upper convex retaining wall, forms a stop platform surface. The inner cavity includes a central area, a coil winding area, and four corner empty areas. Multiple sets of slot plates are arranged in the coil winding area. A wire routing groove is formed between adjacent slot plates. The width of the wire routing groove is greater than the diameter of the wire. The slot plates have inner protrusions spaced along the length direction. The inner protrusions of two sets of adjacent slot plates are arranged on both sides of the corresponding position in the length direction of the wire routing groove to form a wire locking mechanism. The second base plate corresponding to the central area and the four corner empty areas both form an upper convex platform structure.
[0007] The bottom outer periphery of the first base plate is supported on the stop platform surface, the upper convex retaining wall of the coil disc body is assembled in the upper concave positioning groove, and the excitation coil is placed in the coil winding area.
[0008] Its further features are:
[0009] The height of the convex platform structure formed by the central area and the four corner empty areas is the same as the height of the slot plate, making it convenient and reliable to manufacture.
[0010] The second base plate is provided with auxiliary reinforcing ribs on the outer periphery of the convex platform structure formed by the central area and the four corner empty areas. The auxiliary reinforcing ribs and the reinforcing ribs at the normal height of the bottom of the second base plate are connected to form a whole.
[0011] The outer peripheral ring plate has a number of upward-protruding fastener positioning platforms on its stop platform surface. Each fastener positioning platform is connected to the corresponding upward-protruding retaining wall on the outer side. The height of the fastener positioning platform is flush with the upward-protruding retaining wall. A positioning hole is provided on the fastener positioning platform. The first base plate is provided with a contour mounting hole corresponding to the position of the fastener positioning platform. In the assembled state, the fastener positioning platform is inserted into the contour mounting hole to ensure reliable alignment and assembly of the coil body and the water-cooled base plate.
[0012] The outer circumferential ring plate is provided with a clearance notch at the bottom of each fastener positioning platform. The clearance notch facilitates the fastener fixing and also reduces the weight of the entire coil body.
[0013] The slot plate is provided with a cable outlet guide frame that guides from the inner ring to the outer ring at the position of the cable outlet of the first base plate. The guide notch on the cable outlet guide frame is higher than the cable slot to ensure reliable cable lead-out.
[0014] The height of the cable outlet guide frame is flush with the height of the stop platform surface, and the upper end surface of the cable outlet guide frame also serves as the support surface of the first base plate.
[0015] The upper surface of the convex platform structure in the central region is also provided with an convex support strip. The upper surface of the convex support strip is flush with the height of the stop platform surface to ensure reliable support of the first base plate.
[0016] With the structure of this utility model, after the coil is placed on the coil disk body, the glue injection operation is performed. After the glue injection is completed but before the glue is completely cured, the water-cooled base plate is placed on the coil disk body. The convex baffle of the coil disk body is assembled with the concave positioning groove, which can effectively prevent the potting glue from overflowing from the contact surface of the coil disk body and the water-cooled base plate, effectively solving the problem of difficult glue overflow handling, and reducing the labor cost of manual cleaning. The width of the wiring groove is set to be greater than the diameter of the wire, making the wiring of the wire convenient and quick. The wire clamping mechanism is used to reliably position the wire, so that the excitation wire can be well fixed in the wiring groove, which can accommodate wires with uneven thickness. In addition, the second base plate corresponding to the central area of the inner cavity and the four corner empty areas forms an convex platform structure, which reduces the amount of potting glue filling, reducing product weight and cost.

[0023] The water-cooled base plate 10 includes a first base plate 30 and a surrounding ring plate 40. The outer periphery of the first base plate 30 is provided with an upper recessed positioning groove 31 corresponding to the position of the surrounding ring plate 40.
[0024] The coil body 20 includes a second base plate 50, an outer peripheral ring plate 60, and an inner cavity 70. The outer peripheral ring plate 60 is provided with an upper protruding baffle 61. The outer peripheral ring plate 60, after removing the upper surface of the upper protruding baffle 61, forms a stop platform surface 62. The inner cavity 70 includes a central area 71, a coil winding area 72, and four corner empty areas 73. Multiple sets of slot plates 80 are arranged in the coil winding area 72. A wire routing groove 81 is formed between adjacent slot plates 80. The width of the wire routing groove 81 is greater than the diameter of the wire. The slot plates 80 are provided with inner protrusions 82 at intervals along the length direction. The inner protrusions 82 of two sets of adjacent slot plates 80 are arranged on both sides of the corresponding position in the length direction of the wire routing groove 81 to form a wire clamping mechanism 90. The second base plate corresponding to the central area 72 and the four corner empty areas 72 both form an upper protruding platform structure.
[0025] The bottom outer periphery of the first base plate 30 is supported on the stop platform surface 62. The upper convex retaining wall 61 of the coil disc body 20 is assembled with the upper concave positioning groove 31. The excitation coil (not shown in the figure, belonging to existing mature technology) is placed in the coil winding area 72.
[0026] In practice,
[0027] The height of the convex platform structure formed by the central area 71 and the four corner empty areas 73 is flush with the height of the slot plate 80, making the manufacturing convenient and reliable.
[0028] The second base plate 50 is provided with auxiliary reinforcing ribs 51 on the outer periphery of the bottom of the convex platform structure formed by the central area 71 and the four corner empty areas 73. The auxiliary reinforcing ribs 51 and the reinforcing ribs 52 at the normal height of the bottom of the second base plate 50 are connected to form a whole.
[0029] The outer ring plate 60 has a number of upwardly protruding fastener positioning platforms 63 on its stop platform surface 62. Each fastener positioning platform 63 is connected to the corresponding upwardly protruding retaining wall 61 on the outer side. The height of the fastener positioning platform 63 is flush with that of the upwardly protruding retaining wall 61. A positioning hole 64 is provided on the fastener positioning platform 63. The first base plate 30 is provided with a contour mounting hole 32 corresponding to the position of the fastener positioning platform 63. In the assembled state, the fastener positioning platform 62 is inserted into the contour mounting hole 32 to ensure reliable alignment and assembly of the coil body 20 and the water-cooled base plate 10.
[0030] The outer ring plate 60 is provided with a clearance notch 65 at the bottom of each fastener positioning platform 63. The clearance notch 65 facilitates the fastening of the fasteners and also reduces the weight of the entire coil body 20.
[0031] The slot plate 80 is provided with a cable outlet guide frame 83 that guides from the inner ring to the outer ring at the position of the cable outlet 33 of the first base plate 30.

[0032] In practice, the height of the outlet guide frame 83 is level with the height of the stop platform surface 62, and the upper end surface of the outlet guide frame 83 also serves as the support surface of the first base plate 30.
[0033] The upper surface of the convex platform structure in the central region 71 is also provided with an convex support bar 711. The upper surface of the convex support bar 711 is flush with the height of the stop platform surface 62 to ensure reliable support of the first base plate 30.
[0034] Its working principle is as follows: After the coil is placed on the coil disk body, the encapsulation operation is carried out. After the encapsulation is completed, before the encapsulation is completely cured, the water-cooled base plate is placed on the coil disk body. The convex baffle of the coil disk body is assembled with the concave positioning groove, which can effectively prevent the potting compound from overflowing from the contact surface of the coil disk body and the water-cooled base plate. This effectively solves the problem of difficult handling of overflowing compound and reduces the labor cost of manual cleaning. The width of the wiring groove is set to be greater than the diameter of the wire, which makes the wiring of the wire convenient and quick. The wire clamping mechanism is used to reliably position the wire, so that the excitation wire can be well fixed in the wiring groove, which can adapt to wires with uneven diameters. In addition, the second base plate corresponding to the central area of the inner cavity and the four corner empty areas forms an convex platform structure, which reduces the amount of potting compound filling and reduces the weight and cost of the product.
