Description

Technical Field

[0001] This disclosure relates to the technical field of wireless charging, and in particular to an easy-to-assemble wireless charging module. Background Technology

[0002] A wireless charging module is a modular device that integrates wireless charging technology for wireless power transmission and charging. The module is installed in mounting holes on a flat surface. It includes a front cover, a mounting shell, and a connecting cable. The front cover and mounting shell are assembled by tightening screws. One end of the connecting cable has a silicone sleeve. The module has a through-hole for the connecting cable, through which the silicone sleeve is inserted to secure the cable to the module's housing.

[0003] The assembly of the wireless charging module requires tools for the flat shell and the fixed shell, making it inconvenient. Furthermore, the end of the connecting cable assembly with the silicone sheath needs to be inserted into the cable hole, making the assembly of the connecting cable troublesome. The connecting cable is not fixedly connected to the fixed shell, resulting in poor tensile strength of the connecting cable.

[0004] For example, prior art document CN202322024306.8 discloses a multi-purpose wireless charging device, including a housing, a wireless charging module, a main control board, an adapter board, a data cable, and a rotating assembly. The data cable includes independent fixed and retractable cables, with the retractable cable mounted on the rotating assembly. The fixed cable is connected to the main control board, and the retractable cable is connected to the adapter board. The main control board is electrically connected to the adapter board via a connector. The main control board is fixed in the housing, and the adapter board is mounted on the rotating assembly to form a structure that can rotate with the rotating assembly. The internal parts assembly of this solution is relatively cumbersome, and the fixed cable is not connected to the housing for fixation, resulting in poor tensile strength of the fixed cable. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an easy-to-assemble wireless charging module that is convenient to assemble and has good tensile strength.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] An easy-to-assemble wireless charging module includes a charging case assembly, a wireless circuit assembly, and a connecting cable assembly.

[0008] The charging case assembly includes a front shell and a fixed shell, with a receiving cavity formed between the front shell and the fixed shell. The wireless circuit assembly is fixedly installed in the receiving cavity, and the fixed shell is fastened to the front shell.

[0009] The connecting wire assembly includes an integrally injection-molded connecting wire and a protective sleeve. The connecting wire is electrically connected to the wireless circuit assembly. A circuit through hole is provided at the bottom of the fixed housing. The protective sleeve passes through the circuit through hole. The protective sleeve has a first locking block and a second locking block. The circuit through hole is located between the first locking block and the second locking block. The side wall of the fixed housing also has an encapsulation side hole communicating with the circuit through hole. An encapsulation groove is formed on the inner wall of the encapsulation side hole. An encapsulation member protrudes from one end of the face shell adjacent to the fixed housing. The encapsulation member is installed in the encapsulation side hole, and the edge of the encapsulation member is correspondingly embedded in the encapsulation groove.

[0010] In one embodiment, a first tangent circular plane is formed on each side of the face shell, and a second tangent circular plane is formed on each side of the fixed shell, with the two first tangent circular planes and the two second tangent circular planes corresponding to each other.

[0011] In one embodiment, the encapsulation side hole is disposed on the second tangent plane, and the encapsulation component is disposed on the first tangent plane.

[0012] In one embodiment, the housing includes an integrally connected planar portion and an embedded portion, the fixed housing is connected to the end of the embedded portion away from the planar portion, the planar portion and the embedded portion form a stepped structure, and the cross section of the planar portion is larger than the cross section of the embedded portion.

[0013] In one embodiment, the planar portion is provided with an annular groove on the side opposite to the embedded portion, and the annular groove is correspondingly disposed above the wireless circuit assembly.

[0014] In one embodiment, the fixed housing is provided with a plurality of support blocks spaced apart, and the wireless circuit assembly is mounted on the plurality of support blocks.

[0015] In one embodiment, a limiting protrusion is formed at one end of the package opposite to the face shell, a limiting groove is formed in the fixed shell, the limiting protrusion is correspondingly embedded in the limiting groove, and a limiting plane is formed on one side of the wire sheath adjacent to the package.

[0016] In one embodiment, the fixed housing has a connecting protrusion at one end adjacent to the face housing, the connecting protrusion has a fastening groove, and the inner wall of the face housing has a corresponding connecting fastener, which is fastened to the fastening groove.

[0017] In one embodiment, the bottom of the fixed housing is further provided with a strip-shaped heat dissipation hole, which is connected to the receiving cavity.

[0018] In one embodiment, the easily assembled wireless charging module further includes a bidirectional sliding fastener assembly, which is disposed at one end of the fixed housing opposite to the face housing. The bidirectional sliding fastener assembly has two adjustable telescopic ends for fixing the fixed housing in the mounting hole.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] The aforementioned easy-to-assemble wireless charging module uses the first and second locking blocks of the cable protector to engage with the circuit through-hole at the bottom of the fixed housing to initially fix the connecting wire. When the fixed housing and the face housing are fastened together, the encapsulation component slides along the encapsulation groove and embeds into the encapsulation side hole, thereby limiting and fixing the cable protector. This simplifies the process and increases the assembly speed, making the easy-to-assemble wireless charging module convenient to assemble. The connecting wire and the cable protector are integrally injection molded. After the cable protector passes through the circuit through-hole, the first and second locking blocks clamp onto the inner and outer walls of the fixed housing respectively and seal the circuit through-hole, thereby improving the tensile strength of the connecting wire and preventing the connecting wire from falling off due to external pulling force.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 4 As shown, this is an easily assembled wireless charging module 10 according to an embodiment of the present disclosure, including a charging shell assembly 100, a wireless circuit assembly 200, and a connecting cable assembly 300. The charging shell assembly 100 includes a front shell 110 and a fixed shell 120, with a receiving cavity 101 formed between the front shell 110 and the fixed shell 120. The wireless circuit assembly 200 is fixedly installed in the receiving cavity 101, and the fixed shell 120 is fastened to the front shell 110. The wireless circuit assembly 200 integrates a transmitting coil and a circuit board, and the wireless circuit assembly 200 realizes wireless energy transmission through electromagnetic induction.

[0031] Further, the connecting wire assembly 300 includes an integrally injection-molded connecting wire 310 and a wire sheath 320. The connecting wire 310 is electrically connected to the wireless circuit assembly 200. A circuit through-hole 1201 is provided at the bottom of the fixing housing 120. The wire sheath 320 passes through the circuit through-hole 1201. The wire sheath 320 has a first locking block 321 and a second locking block 322. The circuit through-hole 1201 is located between the first locking block 321 and the second locking block 322. The fixing housing 120... The side wall is also provided with an encapsulation side hole 1202 that communicates with the circuit through hole 1201. The inner wall of the encapsulation side hole 1202 is formed with an encapsulation groove 1203. One end of the face shell 110 adjacent to the fixed shell 120 is provided with an encapsulation member 111. The encapsulation member 111 is installed in the encapsulation side hole 1202. The edge of the encapsulation member 111 is correspondingly embedded in the encapsulation groove 1203. The first locking block 321 and the second locking block 322 are used to fix the connecting wire assembly 300 and seal the circuit through hole 1201.

[0032] In this embodiment, the wireless circuit assembly 200 is fixedly installed in the receiving cavity 101. The fixed housing 120 and the face housing 110 are quickly fastened together by a snap-fit ​​structure to form a closed receiving cavity 101 without the need for screws or welding. Then, the integrally injection-molded connecting wire 310 and the wire sheath 320 are installed on the circuit through hole 1201 through the encapsulation side hole 1202. The first locking block 321 and the second locking block 322 of the wire sheath 320 are respectively snapped into the upper and lower edges of the circuit through hole 1201 to form a self-locking structure, preventing the connecting wire 310 from falling off and sealing the circuit through hole 1201. The encapsulation component 111 of the face housing 110 is pushed horizontally into the encapsulation groove 1203 of the fixed housing 120 to complete the sealing of the encapsulation side hole 1202 and the fixing of the wire sheath 320.

[0033] The aforementioned easy-to-assemble wireless charging module 10 achieves initial fixation of the connecting wire 310 by engaging the first and second locking blocks 321 and 322 of the cable sleeve 320 with the circuit through hole 1201 at the bottom of the fixed housing 120. When the fixed housing 120 is fastened to the face housing 110, the encapsulation component 111 slides along the encapsulation groove 1203 and is embedded into the encapsulation side hole 1202, thereby limiting and fixing the cable sleeve 320, simplifying the process and improving the assembly speed, thus making the easy-to-assemble wireless charging module 10 easy to assemble. The connecting wire 310 and the cable sleeve 320 are integrally injection molded. After the cable sleeve 320 passes through the circuit through hole 1201, the first locking block 321 and the second locking block 322 are respectively clamped on the inner and outer walls of the fixed housing 120 and seal the circuit through hole 1201, thereby improving the tensile strength and sealing performance of the connecting wire 310 and preventing the connecting wire 310 from falling off due to external pulling force.

[0034] like Figure 3 As shown, in one embodiment, the face shell 110 has a first tangent circular plane 112 formed on both sides, and the fixed shell 120 has a second tangent circular plane 121 formed on both sides. The two first tangent circular planes 112 and the two second tangent circular planes 121 are correspondingly arranged. In this embodiment, the face shell 110 and the fixed shell 120 are respectively tangent circularly processed to form corresponding first tangent circular planes 112 and second tangent circular planes 121. This allows the fixed shell 120 and the face shell 110 to be fixed in the mounting holes of the corresponding contours. The corresponding tangent circular planes can play a guiding role, enabling the mounting face shell 110 and the fixed shell 120 to be quickly and accurately connected, greatly shortening the assembly time and improving production efficiency.

[0035] like Figure 3 As shown, in one embodiment, the encapsulation side hole 1202 is disposed on the second tangent plane 121, and the encapsulation component 111 is disposed on the first tangent plane 112. In this embodiment, when the encapsulation component 111 is installed in the encapsulation side hole 1202, the first tangent plane 112 and the second tangent plane 121 are planes, so that the transition position between the first tangent plane 112 and the second tangent plane 121 is flat and fits tightly.

[0036] like Figure 3 As shown, in one embodiment, the housing 110 includes an integrally connected planar portion 113 and an insert portion 114. The fixed housing 120 is connected to the end of the insert portion 114 opposite to the planar portion 113. The planar portion 113 and the insert portion 114 form a stepped structure, and the cross-section of the planar portion 113 is larger than the cross-section of the insert portion 114. In this embodiment, the mounting hole of the mounting surface has a mounting groove. Through the stepped structure formed by the planar portion 113 and the insert portion 114, when the housing 110 is installed in the mounting hole of the mounting surface, the planar portion 113 is engaged with the edge of the mounting hole and adapts to the depth of the mounting groove, so that the planar portion 113 is flush with the surface of the mounting surface.

[0037] like Figure 3 As shown, in one embodiment, the planar portion 113 has an annular groove 1101 on the side opposite to the embedded portion 114, and the annular groove 1101 is correspondingly disposed above the wireless circuit assembly 200. In this embodiment, the annular groove 1101 provides a marking and positioning function, thereby quickly and accurately placing the device to be charged in the area within the annular groove 1101 for charging.

[0038] like Figure 3As shown, in one embodiment, a plurality of support blocks 122 are spaced apart within the fixed housing 120, and the wireless circuit assembly 200 is mounted on the plurality of support blocks 122. In this embodiment, the plurality of support blocks 122 support the wireless circuit assembly 200, thereby providing a heat dissipation channel between the wireless circuit assembly 200 and the fixed housing 120, thus improving the heat dissipation efficiency of the wireless circuit assembly 200. The plurality of support blocks 122 are spaced apart within the fixed housing 120, so that the support blocks 122 are subjected to uniform force, and the support blocks 122 can limit the installation position of the wireless circuit assembly 200, reducing the shaking problem of the wireless circuit assembly 200.

[0039] like Figure 4 As shown, in one embodiment, the end of the package 111 facing away from the housing 110 has a limiting protrusion 1111, which is correspondingly embedded in the circuit through hole 1201. The side of the cable sheath 320 adjacent to the package 111 has a limiting plane 323. In this embodiment, the fit between the limiting protrusion 1111 and the contour of the circuit through hole 1201 makes the positioning of the package 111 and the housing 120 more accurate and the connection tighter, ensuring that the side of the package 111 and the cable sheath 320 are properly aligned.

[0040] like Figure 3 and Figure 4 As shown, in one embodiment, the fixed housing 120 has a connecting protrusion 123 protruding from one end adjacent to the face housing 110. The connecting protrusion 123 has a fastening groove 1204, and a corresponding connecting fastener 115 is formed on the inner wall of the face housing 110. The connecting fastener 115 is correspondingly fastened to the fastening groove 1204. In this embodiment, by having the connecting fastener 115 correspondingly fastened to the fastening groove 1204, the fastening between the fixed housing 120 and the face housing 110 is convenient and the connection is tight, thereby speeding up the assembly speed of the fixed housing 120 and the face housing 110.

[0041] like Figure 3 As shown, in one embodiment, the bottom of the fixed housing 120 is further provided with a strip-shaped heat dissipation hole 1205, which communicates with the receiving cavity 101. In this embodiment, the strip-shaped heat dissipation hole 1205 is located at the bottom of the fixed housing 120, which reduces the amount of dust entering the receiving cavity 101. When the wireless circuit assembly 200 is working, it exchanges air with the outside through the strip-shaped heat dissipation hole 1205, thereby improving the heat dissipation effect of the wireless circuit assembly 200 in the receiving cavity 101.

[0042] like Figure 4As shown, in one embodiment, the easily assembled wireless charging module 10 further includes a bidirectional sliding fastener assembly 400. The bidirectional sliding fastener assembly 400 is disposed at the end of the fixed housing 120 opposite to the front housing 110. The bidirectional sliding fastener assembly 400 has two adjustable telescopic ends 410, which are used to fix the fixed housing 120 within the mounting hole. In this embodiment, fixing the fixed housing 120 within the mounting hole using the bidirectional sliding fastener assembly 400 eliminates the need for additional tools, saving installation time. Furthermore, the fastening and retraction of the two telescopic ends 410 of the bidirectional sliding fastener assembly 400 enhances the adaptability of the fixed housing 120 to different hole diameters.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] The aforementioned easy-to-assemble wireless charging module 10 achieves initial fixation of the connecting wire 310 by engaging the first and second locking blocks 321 and 322 of the cable sleeve 320 with the circuit through hole 1201 at the bottom of the fixed housing 120. When the fixed housing 120 is fastened to the face housing 110, the encapsulation component 111 slides along the encapsulation groove 1203 and is embedded into the encapsulation side hole 1202, thereby limiting and fixing the cable sleeve 320, simplifying the process and improving the assembly speed, thus making the easy-to-assemble wireless charging module 10 easy to assemble. The connecting wire 310 and the cable sleeve 320 are integrally injection molded. After the cable sleeve 320 passes through the circuit through hole 1201, the first locking block 321 and the second locking block 322 are respectively clamped on the inner and outer walls of the fixed housing 120 and seal the circuit through hole 1201, thereby improving the tensile strength and sealing performance of the connecting wire 310 and preventing the connecting wire 310 from falling off due to external pulling force.

[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
