The traditional vehicle mobile phone wireless charging device usually adopts an electric lifting mechanism.

[0023] With the popularity of smart mobile devices, vehicle wireless charging devices have become one of the important configurations in the cab of commercial vehicles. The traditional vehicle mobile phone wireless charging device usually adopts an electric lifting mechanism. Although this design improves the sense of technology and convenience to a certain extent, in the actual operating environment of commercial vehicles, the electric lifting mechanism relies on precise transmission components such as motors, screws, and guide rails, resulting in a complex overall structure, a large number of parts, high manufacturing costs, and increased assembly and maintenance difficulties. In the long-term high-frequency use scenario of commercial vehicles, such mechatronic mechanisms are prone to jamming, wear, or poor electrical contact due to environmental factors such as dust, temperature difference, and vibration, affecting the service life and reliability of the device. Commercial vehicle driving is often accompanied by sustained and large-amplitude road vibration and impact.
[0024] To solve the above problems, the embodiments of the present application provide a mobile phone wireless charging box with simple structure, high reliability, and good buffering and damping performance, and an assembling method thereof.
[0025] Referring to Figures 1 to 9 The embodiments of the present application provide a mobile phone wireless charging box. The mobile phone wireless charging box is mainly applied in the cab of a commercial vehicle to provide stable and reliable wireless charging services for the driver's mobile phone or other compatible mobile devices, while effectively adapting to the vibration environment during vehicle driving and protecting the device from impact.
[0026] The mobile phone wireless charging box of the embodiments of the present application includes a base 100, a charging assembly 200, and a buffering device 300 and a damping device 400 connected between the base 100 and the charging assembly 200.
[0027] The base 100 is fixed at a predetermined mounting position (such as a specific area of the center console or instrument panel) in the cab of the vehicle. The base 100 provides support and mounting interfaces for the charging assembly 200, the buffering device 300, and the damping device 400.
[0028] In some examples, the base 100 is provided with a bent edge 110 that bends towards the charging assembly 200. The bent edge 110 extends upwards along the four perimeter edges of the base 100 (i.e. in the direction towards the charging assembly 200). When the charging assembly 200 is lifted relative to the base 100, the bent edge 110 can serve as a lateral guide to limit excessive lateral deviation or rotation of the charging assembly 200 in the horizontal plane, ensuring smoothness and centricity of the lifting movement. The height of the bent edge 110 is slightly lower than or equal to the distance between the lower surface of the housing of the charging assembly 200 at the initial high position and the upper surface of the base 100, so as to avoid interference. In addition, the bent edge 110 is provided with a horizontally extending connecting lug 111, and the bent edge 110 is connected and fixed to the pre-set mounting position through the connecting lug 111.
[0029] The base 100 is provided with a mounting structure for mounting the buffer device 300 and the damping device 400. For example, a plurality of mounting holes, threaded holes or clamping structures can be provided on the bottom surface of the base 100 for fixing the guide sleeve of the buffer device 300 and the cylinder part of the damping device 400. In addition, the base 100 is usually also provided with a wiring hole for the introduction of power lines and signal lines.
[0030] The charging assembly 200 includes a housing 210 and a wireless charging module 220, and the housing 210 provides installation and protection for the wireless charging module 220. The upper surface of the housing 210 is provided with a mobile phone placing plane 211 for directly supporting the mobile phone to be charged.
[0031] The housing 210 is usually designed in a split type to facilitate assembly and maintenance. In a preferred embodiment, the housing 210 includes an upper shell 212 and a lower shell 213 that are detachably connected. The connection between the upper shell 212 and the lower shell 213 can be snap connection, screw connection or a combination of both.
[0032] The upper surface of the upper shell 212 constitutes the mobile phone placing plane 211. The inner side of the upper shell 212 is provided with a mounting groove 2121 for mounting the wireless charging module 220. The shape and size of the mounting groove 2121 are matched with the wireless charging module 220 for accurately fixing the planar position of the wireless charging module 220. In some embodiments, in order to support charging for mobile phones of different sizes or positions, or to provide a more flexible charging area, two or more parallel and spaced mounting grooves 2121 can be provided inside the upper shell 212. As shown, two parallel mounting grooves 2121 are provided inside the upper shell 212, and one wireless charging module 220 can be independently installed in each mounting groove 2121, thereby forming a double charging area that can simultaneously charge two mobile phones or provide a larger effective charging range for one mobile phone. One side of the upper shell 212 is provided with a buckle 2122 for clamping with the corresponding structure of the lower shell 213. Figure 2 As shown, two parallel mounting grooves 2121 are provided inside the upper shell 212, and one wireless charging module 220 can be independently installed in each mounting groove 2121, thereby forming a double charging area that can simultaneously charge two mobile phones or provide a larger effective charging range for one mobile phone. One side of the upper shell 212 is provided with a buckle 2122 for clamping with the corresponding structure of the lower shell 213.
[0033] The lower shell 213 cooperates with the upper shell 212 to form a closed or semi-closed space accommodating the wireless charging module 220. The lower shell 213 is provided with a relief groove 2131 corresponding to the mounting groove 2121 of the upper shell 212. When the upper shell 212 and the lower shell 213 are assembled, one side of the wireless charging module 220 is fixed in the mounting groove 2121 of the upper shell 212, and the other side of the wireless charging module 220 abuts or slightly sinks into the groove edge of the relief groove 2131 of the lower shell 213, thereby achieving the limiting and fixing of the wireless charging module 220 in the thickness direction and preventing it from shaking in the shell. One side of the lower shell 213 is provided with a clamping groove 2132 cooperating with the buckle 2122 of the upper shell 212. Through the cooperation of the buckle 2122 and the clamping groove 2132, the upper shell 212 and the lower shell 213 can be quickly buckled and connected.
[0034] The wireless charging module 220 is a standard wireless power transmission component. The wireless charging module 220 is installed in the mounting groove 2121 of the upper shell 212 and is supported by the groove edge of the relief groove 2131. Its power supply line and communication cable are led out from the side or bottom of the shell 210 and connected to the vehicle power supply system through the wire hole of the base 100.
[0035] The charging assembly 200 is connected to the base 100 through a plurality of buffer devices 300. Each buffer device 300 is arrayed between the base 100 and the charging assembly 200, and their joint action enables the charging assembly 200 to move smoothly up and down relative to the base 100.
[0036] The buffer device 300 is used to realize the elastic lifting function of the charging assembly 200. When the mobile phone is not placed, the charging assembly 200 is supported at the initial high position, and when the mobile phone is placed on the mobile phone placing plane 211, the weight of the mobile phone causes the charging assembly 200 to overcome the elastic force of the buffer device 300 and descend. In this process, the elastic deformation of the buffer device 300 absorbs most of the kinetic energy of the falling mobile phone, converting the hard impact into a soft and slow descent. During vehicle driving, vibrations caused by uneven road surfaces are transmitted through the base 100. The elasticity of the buffer device 300 can isolate and absorb part of the high-frequency and small-amplitude vibrations, preventing them from being directly transmitted to the charging assembly 200 and the mobile phone on it, and improving the stability of the charging process.
[0037] The buffer device 300 is provided in multiple numbers and arrayed between the base 100 and the charging assembly 200. This multi-point array support mode (such as four-corner support) can ensure that the charging assembly 200 moves smoothly up and down without tilting or jamming, and the stress is uniform. Each buffer device 300 has at least one end as an elastic movable end.
[0038] In a preferred embodiment of the present application, each buffer device 300 specifically comprises a guide post 310, a guide sleeve 320, and an elastic component 330.
[0039] The guide post 310 serves to provide precise linear guidance, limiting the movement of the charging assembly 200 to a direction perpendicular to the base 100, preventing lateral swinging or rotation. One end of the guide post 310 is fixed vertically on the lower shell 213. The fixing method can be threaded connection, interference fit, or through an end plate.
[0040] In a specific implementation, one end of the guide post 310 is provided with a first end plate 311. The first end plate 311 is fixed on the inner bottom surface of the lower shell 213 by screws. The lower shell 213 is provided with a first through hole, and the rod portion of the guide post 310 is arranged in the first through hole and extends downward (away from the shell). The size of the first end plate 311 is larger than the hole diameter of the first through hole, so as to axially fix the guide post 310 on the lower shell 213, while allowing the rod to freely pass through the first through hole.
[0041] The guide sleeve 320 serves as a sliding sleeve for the guide post 310, and cooperates with the guide post 310 to form a precise guide pair. One end of the guide sleeve 320 is fixed on the bottom surface of the base 100. The fixing method can also be threaded connection, clamping, or through an end plate. For example, in a specific implementation, one end of the guide sleeve 320 is provided with a second end plate 321. The second end plate 321 is fixed on the bottom surface of the base 100 by screws. The bottom surface of the base 100 is provided with a second through hole corresponding in position, and the sleeve portion of the guide sleeve 320 is arranged in the second through hole and extends upward (away from the bottom surface of the base). The size of the second end plate 321 is larger than the hole diameter of the second through hole, so as to axially fix the guide sleeve 320 on the base 100, while allowing the sleeve to freely pass through the second through hole.
[0042] During assembly, the rod of the guide post 310 on the charging assembly 200 is inserted into the sleeve of the corresponding guide sleeve 320 on the base 100. The guide post 310 can freely slide axially in the guide sleeve 320. The inner wall of the guide sleeve 320 and the outer wall of the guide post 310 are in clearance fit, and usually have lubricating grease to reduce friction and wear.
[0043] The elastic component 330 provides the restoring force and is the key to the cushioning function. The elastic component 330 is sleeved on the outer wall of the guide sleeve 320. More specifically, one end of the elastic component 330 is connected to the inner side of the bottom surface of the base 100, and the other end is connected to the outer side of the bottom surface of the lower shell 213. In a preferred embodiment, the elastic component 330 is a spring. The spring is sleeved on the outside of the guide sleeve 320, which can prevent the spring from bending unstably when compressed and save installation space, making the structure more compact. When the charging assembly 200 is not subjected to external force, the spring is in a free state, lifting the charging assembly 200 to an initial high position. When the mobile phone is placed, the charging assembly 200 descends, and the spring is further compressed, storing elastic potential energy. When the mobile phone is removed, the spring releases the potential energy, pushing the charging assembly 200 back to the initial high position.
[0044] The number and layout of the buffer devices 300 need to be determined according to the weight, size, and required support stability of the charging assembly 200. In a specific embodiment, four buffer devices 300 are provided, each located near a corner of the housing of the charging assembly 200. This four-point support layout can provide optimal stability and balanced stress.
[0045] The damping device 400 provides a damping effect on the lifting movement of the charging assembly 200, especially the descending and rebounding movement. Specifically: when the mobile phone is placed, without damping, the charging assembly 200 may quickly descend to the bottom under the action of gravity and spring force, still possibly producing a certain impact feeling. The damping device 400 provides a resistance related to the speed of movement, making the descending process of the charging assembly 200 a smooth and slow "soft landing", providing a better feel and further reducing impact. When the mobile phone is removed, the spring will quickly push the charging assembly 200 back to the high position. Without damping, the charging assembly 200 may oscillate up and down near the initial position several times before stabilizing. The damping device 400 can quickly dissipate the energy released by the spring, allowing the charging assembly 200 to return smoothly and without oscillation to the initial position. In a vehicle vibration environment, the damping device 400 can form a "spring-damping" system with the spring, which can effectively attenuate vibrations of a specific frequency range and prevent the transmission of a large amount of vibration energy between the base 100 and the charging assembly 200.
[0046] The damping device 400 is connected to the base 100 and the charging assembly 200 at both ends. The damping device 400 has at least one damping movable end. This means that the damping device 400 itself contains a movable component (such as a piston rod), and a damping force is generated between this moving component and the other end (cylinder).
[0047] In a preferred embodiment, in combination with the layout of four buffering devices 300, the damping device 400 comprises two hydraulic dampers 410. Hydraulic damper 410 is a mature and reliable linear damping element, whose damping force is proportional to the piston movement speed, and its performance is stable. The two hydraulic dampers 410 are arrayed together with the four buffering devices 300 between the shell 210 and the base 100. For example, as shown in Figure 7 the guide sleeve 320 of the four buffering devices 300 is arranged at the four corner points of the base 100, and the cylinder body of the two hydraulic dampers 410 can be arranged at the middle position of the two long sides of the rectangle. This combination of “four buffering + two damping” can not only provide stable support and guidance, but also achieve excellent dynamic damping effect at a reasonable cost.
[0048] One end (i.e. the cylinder body end) of the hydraulic damper 410 is directly connected to the bottom surface of the base 100, and the other end (i.e. the piston rod end) is connected to the lower shell 213 of the charging assembly 200 through a connecting head. The extension and retraction movement direction of the piston rod is consistent with the movement direction of the guide column 310 of the buffering device 300. When the charging assembly 200 is lifted, the piston rod of the hydraulic damper 410 is moved, and the hydraulic oil in the cylinder body flows through the specially designed throttle hole to generate damping force.
[0049] The working process of the mobile phone wireless charging box of the embodiment of the application will be described in detail below with reference to the accompanying drawings: When no mobile phone is placed in the charging box, the charging assembly 200 is in an “initial high position” relative to the base 100 under the support of the elastic components 330 of the multiple buffering devices 300. At this time, the mobile phone placement plane 211 is at a height that is convenient for the user to place the mobile phone. When the user places the mobile phone on the mobile phone placement plane 211 of the charging assembly 200, the weight of the mobile phone is applied to the charging assembly 200, generating a downward force. This force overcomes the combined force of all springs and the initial damping force of the damping device 400, and the charging assembly 200 begins to slowly descend relative to the base 100. In this process, each spring is further compressed, and the elastic deformation absorbs most of the kinetic energy of the falling mobile phone. The spring force increases with the increase of the compression amount, and at the same time, the four guide columns 310 synchronously and smoothly slide in the corresponding guide sleeves 320, ensuring that the charging assembly 200 always remains horizontal and does not shake laterally, and the piston rod of the two hydraulic dampers 410 is pressed into the cylinder body. The movement of the piston forces the hydraulic oil to flow through the small throttle hole, generating a damping force proportional to the descending speed. This damping force controls the descending speed, and the entire descending process is smooth, slow and quiet, and the user feels a soft “slow descent” feeling, avoiding hard impact, and the charging assembly 200 finally stabilizes at a lower “working low position”, at which the weight of the mobile phone and the compression force of the spring and the damping force reach a balance.
[0050] In the "working low position", the wireless charging module 220 is powered on and starts to charge the phone wirelessly. Due to the spring and damping device, most of the vibration during vehicle driving is isolated, and the charging process is stable and reliable. When the user takes away the phone, the downward load applied to the charging assembly 200 suddenly disappears. The elastic potential energy stored by the compressed elastic component 330 is immediately released, trying to quickly push the charging assembly 200 back to the initial high position, and in this rebound process, the piston rod of the hydraulic damper 410 is pulled out of the cylinder. Similarly, the piston movement is hindered by the throttling of the hydraulic oil, generating a damping force proportional to the rising speed. This damping force quickly consumes the energy released by the spring, and under the action of the damping force, the charging assembly 200 is not suddenly bounced up and oscillated, but smoothly and slowly rises, and finally makes the charging assembly 200 smoothly return to the "initial high position" and prepare for the next use.
[0051] During vehicle driving, the base 100 will bear complex vibrations from the road together with the vehicle body. The buffer device 300 and the damping device 400 jointly constitute a vibration isolation system for the charging assembly 200, so as to play a good isolation effect on high-frequency and small-amplitude vibrations.
[0052] The embodiment of the present application also provides an assembling method of the above-mentioned wireless charging box for mobile phone. The assembling method mainly comprises the following steps: S1: installing the wireless charging module 220 to the upper shell 212.
[0053] Align the wireless charging module 220 with the installation slot 2121 on the inner side of the upper shell 212, put it in and fix it. The fixing method can be buckle, double-sided adhesive, thermal conductive glue or screw. If the upper shell 212 has multiple installation slots, repeat this step to install multiple wireless charging modules. Connect the cable of the wireless charging module 220 and lead it out from the preset cable outlet of the upper shell 212.
[0054] S2: installing multiple array-distributed guide columns 310 on the lower shell 213.
[0055] One end of the guide column 310 with the first end plate 311 is installed on the lower shell 213 in a preset fixed position by screw fastening, clamping or pressing. Ensure that the axis of all guide columns 310 is substantially perpendicular to the bottom surface of the lower shell 213, and its distribution position (such as four corners) meets the design array. The rod body part of the guide column 310 extends downward through the first through hole on the lower shell 213.
[0056] S3: installing the guide sleeve 320, the elastic component 330 and the damping device 400 on the base 100.
[0057] The end of the guide sleeve 320 with the second end plate 321 is installed on the bottom surface of the base 100 at the pre-set fixed position by screwing or clamping. The distribution pattern, number and spacing of the guide sleeves 320 must be completely consistent with the guide posts 310 installed on the lower shell 213 in step S2. The sleeve part of the guide sleeve 320 protrudes upward through the second through hole on the base 100, and the elastic member 330 is sleeved on the outer wall of each guide sleeve 320. One end of the elastic member 330 can be clamped on the flange of the second end plate 321 in advance, or it can be in contact with the bottom surface of the base later.
[0058] The fixed end of the damping device 400 is installed on the corresponding position of the bottom surface of the base 100. When installing, pay attention to the extension direction of the piston rod of the damper should be perpendicular to the plane of the base.
[0059] S4: Assemble the charging assembly.
[0060] Align the upper shell 212 with the wireless charging module 220 installed with the lower shell 213 with the guide posts 310 installed. Align the buckle 2122 on one side of the upper shell 212 with the clamping groove 2132 on one side of the lower shell 213, apply pressure to make it lock, form a complete charging assembly 200. It can also be assisted by a small amount of screws for reinforcement. Ensure that the cable of the wireless charging module 220 is smoothly led out from the opening on the side or bottom of the shell.
[0061] S5: Assemble and connect the charging assembly 200 and the base 100.
[0062] Lift the charging assembly 200, so that the rod body of each guide post 310 on the bottom of the lower shell 213 is aligned with the sleeve inlet of each guide sleeve 320 already installed on the base 100, then slowly and vertically lower the charging assembly 200. During this process, the rod body of each guide post 310 gradually slides into the corresponding guide sleeve 320, and as the charging assembly 200 continues to descend, the upper end of the elastic member 330 (spring) sleeved on the guide sleeve 320 will contact the bottom surface of the lower shell 213, and continue to lower, the spring starts to be compressed, when the charging assembly 200 is lowered to a certain position, the connecting head of the piston rod end of the damping device 400 (hydraulic damper 410) will contact the corresponding connecting point on the lower shell 213. At this time, tools are needed to fix the piston rod connecting head of the hydraulic damper 410 to the connecting point on the lower shell 213. Finally, when the charging assembly 200 is lowered to the position corresponding to its initial high position, stop pressing down. At this time, all guide posts 310 and guide sleeves 320 are in place, all springs are pre-compressed to the designed length, providing initial support force, and all damping devices 400 are connected.
[0063] Through the above assembly method, the assembly of the mobile phone wireless charging box can be efficiently and reliably completed. The components have high modularization degree, facilitating the pre-assembly of wires, and the final assembly step relies on the automatic alignment of the guide column and the guide sleeve, reducing the assembly difficulty and the requirement for worker skills, and being conducive to ensuring the product quality consistency of mass production.
[0064] The mobile phone wireless charging box provided in the application completely abandons the complex electric lifting mechanism (motor, screw rod, guide rail, etc.), and adopts a combination of a pure mechanical buffer spring, a guide column, a guide sleeve and a hydraulic damper 410. The number of components is greatly reduced, the structure is simple and reliable, and the electrical faults, mechanical jamming and wear problems easily occurring in the electric mechanism in the vehicle-mounted harsh environment are avoided. Moreover, compared with the mechatronic structure, the material cost and manufacturing cost of the mechanical structure are significantly reduced. The assembly and maintenance are also more convenient. The vibration isolation system composed of the spring and the damper can effectively attenuate the vibration transmitted during the vehicle driving, providing a stable working platform for the mobile phone during the charging process, improving the reliability and continuity of the charging, and prolonging the service life of the equipment.
[0065] The mobile phone wireless charging box assembly method provided in the application simplifies the assembly process, improves the assembly efficiency and consistency, and is suitable for large-scale production.
[0066] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the application.
