DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: referring to Figure 1 - Fig.13The present invention discloses a vehicle-mounted mobile phone wireless charger capable of adsorption and limiting, comprising a charger body 1, the charger body 1 being a magnetic vehicle-mounted mobile phone wireless charger, a fixing frame 2 being sleeved on the outer peripheral side of the charger body 1, and the charger body 1 being fixedly penetrated through the inner hole of the fixing frame 2, the front and rear sides of the charger body 1 being coplanar with the front and rear sides of the fixing frame 2 respectively, a positioning component 3 being provided on the outer peripheral side of the fixing frame 2, the positioning component 3 comprising a baffle 31, a storage slot 32 being provided at the middle position on the right side of the baffle 31, the fixing frame 2 being arranged in the storage slot 32, and the fixing frame 2 The rear side wall and the outer peripheral wall of the fixed frame 2 are in contact with the inner wall of the storage groove 32, the front side of the fixed frame 2 is coplanar with the front side of the baffle 31, and two clamping plates 33 are arranged on the left and right sides of the baffle 31. Two rectangular grooves 34 are arranged in the baffle 31, and the two rectangular grooves 34 are arranged on the upper and lower sides of the storage groove 32. A magnetic plate 35 is slidably installed in the rectangular groove 34, and an annular groove 39 is arranged on the outer peripheral wall of the magnetic plate 35. A sealing ring 36 is fixedly installed in the annular groove 39, and the outer peripheral wall of the sealing ring 36 is in contact with the inner wall of the corresponding rectangular groove 34; A connecting mechanism 4 is provided on the outer peripheral side of the fixed frame 2 , an adjusting mechanism 5 is provided at a position in the baffle 31 corresponding to the clamping plate 33 , and an anti-slip mechanism 6 is provided on the frame wall of the fixed frame 2 .

[0021] In this embodiment, when the improved vehicle-mounted mobile phone wireless charger is used, the operator inserts the fixing frame 2 and the charger body 1 into the storage slot 32. At this time, the attraction between the charger body 1 and the magnetic plate 35 pulls the magnetic plate 35 toward the fixing frame 2, thereby driving the connection mechanism 4 to operate and apply a restraining limit force to the fixing frame 2, so that the fixing frame 2 is placed in the storage slot 32 more stably. At the same time, the anti-slip mechanism 6 can simultaneously apply an additional limit constraint force to enhance the connection effect between the charger body 1 and the baffle 31, so that the charger body 1 can be connected to the baffle 31 without being subjected to a large external force. 1 is stably connected, and finally the charger body 1 and the baffle 31 form a complete vehicle-mounted mobile phone wireless charger. Then the operator inserts the mobile phone between the two clamping plates 33. At the same time, due to the attraction between the charger body 1 and the mobile phone, the mobile phone can be adsorbed and fixed on the baffle 31. At the same time, the negative pressure cavity in the rectangular groove 34 can drive the adjustment mechanism 5 to apply a pulling force in the opposite direction to the two clamping plates 33. Finally, the two clamping plates 33 clamp the mobile phone to position the mobile phone, so that when the vehicle is shaking, the mobile phone will not slide off the baffle 31 due to its own inertia force, affecting the use of the vehicle-mounted wireless charger; It should be noted that after the mobile phone and the baffle 31 are fitted and fixed, the connection between the baffle 31 and the mobile phone can be locked due to the mutual interference between the mobile phone and the clamping plate 33 and the pressure of the mobile phone on the adsorption mechanism, so that the mobile phone, the baffle 31 and the fixing frame 2 are connected as a whole, so that the charging operation of the charger body 1 on the mobile phone remains stable; When the rear-seat passenger or the front passenger uses the device, the front passenger holds the baffle 31 with one hand and pushes the charger body 1 toward the right opening of the storage slot 32 with the other hand. The connection mechanism 4 and the adsorption mechanism automatically release the restraint limit state of the fixing frame 2, so that the charger body 1 can slide directly out of the storage slot 32. Then the front passenger or the rear-seat passenger directly adsorbs and fixes the charger body 1 to the rear side of the mobile phone, and at the same time, the anti-slip mechanism 6 can apply an adsorption constraint force between the fixing frame 2 and the mobile phone, so that a large friction force is generated between the mobile phone and the charger body 1, so that the charger body 1 will not slide off the mobile phone due to the inertia force when the mobile phone moves, affecting the charging operation of the charger body 1 on the mobile phone. After the charger body 1 is installed on the rear side of the mobile phone, the mobile phone can be temporarily charged directly through the charger body 1, so that the vehicle-mounted mobile phone wireless charger can cope with the use of people in various positions in the vehicle; It should be noted that the charger body 1 is provided with a battery for storing electric energy. When the charger body 1 is connected to an external power source, the external power source is used to charge the mobile phone and the battery inside the charger body 1 is replenished simultaneously. When the charger body 1 is not connected to an external power source, the internal battery provides electric energy for charging the mobile phone. It should be noted that a universal adjustment rod is provided at the middle position of the rear side of the baffle 31 to fix the baffle 31 to the inner shell of the vehicle.

[0022] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, four support bars 37 are relatively fixedly mounted at the upper and lower ends of the front side of the baffle 31, and the spacing between two adjacent support bars 37 is equal, and the outer peripheral wall of the support bar 37 is set in an arc shape; In this embodiment, after the mobile phone is adsorbed and fixed on the baffle 31, due to the mutual interference between the support bar 37 and the upper and lower side walls of the mobile phone, the mobile phone can be constrained and limited by the upper and lower sides of the mobile phone so that the mobile phone will not slide down from the baffle 31 in the upper and lower directions.

[0023] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, the power connection interface of the charger body 1 is fixedly passed through the frame wall of the fixed frame 2, and a charging plug 38 is fixedly installed at the middle position of the left inner wall of the storage slot 32, and the right end of the charging plug 38 is slidably inserted into the power connection interface of the charger body 1; In this embodiment, when the charger body 1 is inserted into the storage slot 32, as the left side of the fixing frame 2 and the left inner wall of the storage slot 32 approach each other, the charging plug 38 is aligned with the power connection interface of the charger body 1 due to the mutual interference between the fixing frame 2 and the inner wall of the storage slot 32, and after the fixing frame 2 and the inner wall of the left end of the storage slot 32 are attached, the charging plug 38 is directly inserted into the power connection interface of the charger body 1. At this time, the charger body 1 is connected to the internal power interface of the vehicle through the charging plug 38, the charging interface and the connecting line. The charging operation of the charger body 1 is powered by the internal power supply of the vehicle, and the operator does not need to perform other operations, which facilitates the assembly operation of the charger body 1 and the baffle 31; It should be noted that a charging interface is provided on the bottom side of the baffle 31 , and the charging plug 38 is connected to the internal power interface of the vehicle through a connecting line and the charging interface.

[0024] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig. 9 As shown, the connection mechanism 4 includes a plurality of limit rods 42, and a plurality of circular holes 41 are relatively opened at positions corresponding to the rectangular grooves 34 on the inner wall of the storage groove 32, and the spacing between two adjacent circular holes 41 is equal. The limit rod 42 is slidably penetrated and installed in the corresponding circular hole 41, and one end of the limit rod 42 is fixedly connected to the corresponding magnetic plate 35, and the other end of the limit rod 42 is hemispherical. Limit grooves 43 with a three-quarter hemispherical shape are opened at positions corresponding to the circular holes 41 on the upper and lower sides of the fixed frame 2, and the hemispherical end of the limit rod 42 is inserted into the corresponding limit groove 43 and contacts with the inner wall of the corresponding limit groove 43; In this embodiment, during the process of inserting the charger body 1 into the storage slot 32, an attraction is generated between the charger body 1 and the magnetic plate 35, thereby pulling the magnetic plate 35 toward the charger body 1, until the limiting rod 42 passes through the circular hole 41 and the magnetic plate 35 contacts the inner wall of the rectangular slot 34, and after the left side of the fixing frame 2 is fitted with the inner wall of the left end of the storage slot 32, the limiting rod 42 is aligned with the limiting slot 43, and at this time, the hemispherical end of the limiting rod 42 is directly inserted into the limiting slot 43, and then through the mutual contact between the hemispherical end of the limiting rod 42 and the inner wall of the limiting slot 43, a restraining limiting force is applied to the fixing frame 2, so that the charger body 1 is relatively stably placed in the storage slot 32 without being subjected to external force, and the operator does not need to perform other operations, which facilitates the assembly operation of the charger body 1 and the baffle 31; When the charger body 1 is pulled out of the storage slot 32, due to the mutual interference between the hemispherical end of the limiting rod 42 and the inner arc wall of the limiting slot 43, the hemispherical end of the positioning rod 64 can be directly squeezed out of the positioning slot 69 along the outer arc wall of the hemispherical end of the positioning rod 64, thereby automatically releasing the restraining limit state between the fixed frame 2 and the baffle 31, so that the operator can push the charger body 1 to slide directly out of the storage slot 32, without the operator having to perform other operations, thereby facilitating the assembly operation of the charger body 1 and the baffle 31.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 7 As shown, the clamping plate 33 is mainly divided into three parts: two adjustment plates 331 and a round rod 332. The cross-section of the adjustment plate 331 is L-shaped, and both ends of the round rod 332 are fixedly connected to one end of the corresponding adjustment plate 331. The other end of the adjustment plate 331 is rotatably connected to the side wall of the baffle 31 through a rotating shaft and a connecting block. In this embodiment, when the operator takes the mobile phone, the operator moves the round rod 332 to both sides with his fingers, and then passes his fingers through the gap between the round rod 332 and the adjustment plate 331, so that the operator's fingers can be directly moved to both sides of the mobile phone, so that the operator can directly remove the mobile phone from the baffle 31 by pulling the mobile phone in hand, which makes it more convenient to take the mobile phone.

[0026] In a further preferred embodiment of the present invention, Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the adjustment mechanism 5 includes a plurality of elastic rods 54, a plurality of air storage grooves 51 are provided at positions corresponding to the adjustment plates 331 in the baffle plate 31, and the spacing between two adjacent air storage grooves 51 is equal, the interior of the air storage groove 51 is connected to the interior of the corresponding rectangular groove 34 through a connecting hole 52, a first piston plate 53 is slidably mounted in the air storage groove 51, one end of the elastic rod 54 is fixedly connected to the center position of the corresponding first piston plate 53, the other end of the elastic rod 54 extends to the outside of the baffle plate 31 and is fixedly connected to the corresponding adjustment plate 331, and the elastic rod 54 is slidably connected to the plate wall of the baffle plate 31; In this embodiment, the magnetic plate 35 can expand the space between the magnetic plate 35 and the first piston plate 53 during the process of moving toward the fixed frame 2, so that a relatively strong negative pressure chamber is formed in the rectangular groove 34 and the air storage tank 51. At this time, the negative pressure chamber in the rectangular groove 34 and the air storage tank 51 can apply a corresponding strength of tension to the adjustment plate 331 through the first piston plate 53 and the elastic rod 54, so that the adjustment plate 331 is in close contact with the side wall of the baffle 31, so that the adjustment plate 331 can stably maintain a vertical state without being subjected to a large external force. The charger body 1 and the baffle 31 form a complete vehicle-mounted mobile phone wireless charger. The adjustment plate 331 applies a restraining force to the mobile phone from the left and right sides of the mobile phone, so that the mobile phone will not slide out from the left and right sides of the baffle 31 when the vehicle shakes, and the mutual interference between the left and right sides of the mobile phone and the round rod 332 can be used to restrain the mobile phone from the front side of the mobile phone, so that when the vehicle shakes, the mobile phone will not move to the front side of the baffle 31, thereby causing the mobile phone to separate from the baffle 31; After the above-mentioned charger body 1 and the fixing plate are separated, due to the pulling of the negative pressure cavity in the rectangular groove 34 on the magnetic plate 35, the magnetic plate 35 slides and resets in the direction away from the storage groove 32 until the magnetic plate 35 and the inner wall of the rectangular groove 34 collide with each other. At this time, when the magnetic plate 35 slides in the direction of the storage groove 32, the gas sucked out from the gas storage groove 51 through the connecting hole 52 is pushed back into the gas storage groove 51. At this time, a negative pressure cavity with smaller strength is formed in the gas storage groove 51, so that the splint 33 is subjected to a smaller pulling force. After the charger body 1 is separated, the remaining device can continue to be used as a mobile phone holder.

[0027] In a further preferred embodiment of the present invention, Figure 8 - Fig.11 As shown, the anti-slip mechanism 6 includes a plurality of second piston plates 62, a plurality of adsorption holes 61 with a cross-shaped cross section are opened on the top of the fixed frame 2, and the spacing between two adjacent adsorption holes 61 is equal, the adsorption holes 61 are located between the plurality of limit grooves 43, and the second piston plates 62 are slidably mounted in the corresponding adsorption holes 61; In this embodiment, after the operator charger body 1 is installed on the rear side of the mobile phone, the second piston plate 62 moves in the adsorption hole 61, so that a negative pressure chamber is formed in the adsorption hole 61, thereby forming an additional adsorption force between the mobile phone and the charger body 1 to enhance the stability of the charger placed on the rear side of the mobile phone.

[0028] In a further preferred embodiment of the present invention, Fig.11 As shown, a spring 63 is provided between the second piston plate 62 and the inner wall of the corresponding adsorption hole 61, and the two ends of the spring 63 are fixedly connected to the corresponding second piston plate 62 and the inner wall of the corresponding adsorption hole 61 respectively; In this embodiment, after the charger body 1 is attached to the rear side of the mobile phone, the spring 63 pushes the second piston plate 62 to move away from the mobile phone, thereby expanding the space on the outer peripheral side of the spring 63, and finally forming a negative pressure cavity on the outer peripheral side of the spring 63. The formation of the negative pressure cavity in the adsorption hole 61 will not exert a reaction force on the mobile phone and affect the magnetic attraction effect between the charger body 1 and the mobile phone.

[0029] In a further preferred embodiment of the present invention, Fig.10 - Fig.13 As shown, a positioning rod 64 is fixedly installed through the center position of the second piston plate 62, and the positioning rod 64 is slidably connected to the inner wall of the corresponding adsorption hole 61, a sealing ring 65 is fixedly installed at the position corresponding to the positioning rod 64 in the frame wall of the fixed frame 2, and the inner peripheral wall of the sealing ring 65 is in contact with the outer peripheral wall of one end of the corresponding positioning rod 64, an adsorption groove 66 is opened at one end of the positioning rod 64, and the interior of the adsorption groove 66 is connected to the interior of the corresponding adsorption hole 61 through a plurality of air guide holes 67, a soft ring 68 is fixedly installed in the adsorption groove 66, and the front end of the soft ring 68 extends to the outside of the corresponding adsorption groove 66, and the outer ring edge of the front end of the soft ring 68 is set in an arc shape; In this embodiment, when the operator installs the charger body 1 on the rear side of the mobile phone, the operator holds the fixing frame 2 with the thumb and the little finger, and presses the hemispherical end of the positioning rod 64 with the remaining fingers, so that the hemisphere of the positioning rod 64 is pressed into the adsorption hole 61, and the second piston plate 62 is driven to compress the spring 63. The setting of the anti-slip mechanism 6 will not affect the operator placing the charger body 1 on the rear side of the mobile phone with one hand; When the above-mentioned operator installs the charger body 1 on the back side of the mobile phone, as the back side of the mobile phone approaches the baffle 31, the back side of the mobile phone will first fit with the soft ring 68. At this time, due to the pressure of the mobile phone on the soft ring 68, the soft ring 68 shrinks and deforms until the back side of the mobile phone and the positioning rod 64 conflict with each other. Then, as the back side of the mobile phone and the charger body 1 approach and fit, the positioning rod 64 can be gradually pressed into the adsorption groove 66 by the attraction between the mobile phone and the charger body 1. At this time, due to the fit of the soft ring 68 and the back wall of the mobile phone, the opening of the adsorption hole 61 can be directly blocked. At the same time, as the positioning rod 64 gradually shrinks into the adsorption hole 61, the second piston plate 62 can be driven to reset and move synchronously, so that the closed space around the spring 63 becomes larger, and since there is no inflow of external gas, a negative pressure cavity is formed around the spring 63 and in the adsorption hole 61, thereby forming an additional adsorption constraint force between the mobile phone and the charging body to enhance the combined positioning effect between the charger body 1 and the mobile phone. The installation of the positioning rod 64 will not affect the adsorption operation of the negative pressure cavity in the adsorption hole 61 on the back side of the mobile phone.

[0030] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.11 As shown, the front end of the positioning rod 64 is coplanar with the front side of the fixing frame 2, and the rear end of the positioning rod 64 is hemispherical, and a positioning groove 69 with a three-quarter hemispherical shape is opened at the position corresponding to the positioning rod 64 on the rear inner wall of the storage groove 32, and the rear end of the positioning rod 64 is inserted into the corresponding positioning groove 69 and contacts the inner wall of the corresponding positioning groove 69; In this embodiment, during the process of inserting the fixing frame 2 into the storage slot 32, due to the mutual interference between the opening edge of the storage slot 32 and the hemispherical end of the positioning rod 64, the positioning rod 64 can be squeezed into the adsorption hole 61 along the arc surface of the hemispherical end of the positioning rod 64, so that the operator can push the fixing frame 2 directly into the storage slot 32, which facilitates the assembly operation between the charger body 1 and the baffle 31; After the above-mentioned fixed frame 2 is inserted into the storage groove 32, the hemispherical end of the positioning rod 64 is synchronously aligned with the positioning groove 69, and at this time, due to the push of the spring 63 on the second piston plate 62, the hemispherical end of the positioning rod 64 is automatically inserted into the positioning groove 69. At this time, due to the mutual interference between the hemispherical end of the positioning rod 64 and the inner wall of the positioning groove 69, a restraining limit force can be applied to the fixed frame 2 to further enhance the stability of the assembly between the charger body 1 and the baffle 31.

[0031] Working principle: When the rear-seat passengers or the front passenger use the improved adsorbable and limitable vehicle-mounted wireless charger for mobile phones, the front passenger can hold the baffle 31 with one hand and push the charger body 1 toward the right opening of the storage slot 32 with the other hand. At this time, due to the mutual interference between the hemispherical end of the positioning rod 64 and the inner arc wall of the positioning slot 69 and the mutual interference between the hemispherical end of the limiting rod 42 and the inner arc wall of the limiting slot 43, the hemispherical end of the positioning rod 64 can be directly squeezed out of the positioning slot 69 along the outer arc wall of the hemispherical end of the positioning rod 64, and the hemispherical end of the limiting rod 42 can be squeezed out of the limiting slot 43 along the outer arc wall of the hemispherical end of the limiting rod 42, thereby automatically releasing the restraint and limit state between the fixed frame 2 and the baffle 31, so that the charger body 1 can slide directly out of the storage slot 32, and finally the device is split into two parts; After the charger body 1 is disassembled, the co-pilot or the rear seat passenger holds the fixing frame 2 with the thumb and little finger, and presses the hemispherical end of the positioning rod 64 with the remaining fingers, so that the hemisphere of the positioning rod 64 is pressed into the adsorption hole 61, and the second piston plate 62 is driven to compress the spring 63, and then the charger body 1 is brought close to the corresponding position on the rear side of the mobile phone. After the distance between the mobile phone and the charger body 1 reaches the threshold, the charger body 1 is relatively stably adsorbed and fixed on the corresponding position on the rear side of the mobile phone due to the attraction and adsorption constraint between the charger body 1 and the mobile phone; When the charger body 1 approaches the back side of the mobile phone, the back side of the mobile phone will first contact the soft ring 68. At this time, due to the pressure of the mobile phone on the soft ring 68, the soft ring 68 shrinks and deforms until the back side of the mobile phone and the positioning rod 64 conflict with each other. Then, as the back side of the mobile phone and the charger body 1 approach and fit, the positioning rod 64 can be gradually pressed into the adsorption groove 66 by the attraction between the mobile phone and the charger body 1. At this time, due to the fit of the soft ring 68 and the back wall of the mobile phone, the opening of the adsorption hole 61 can be directly blocked. At the same time, as the positioning rod 64 gradually shrinks into the adsorption hole 61, the second piston plate 62 can be driven to reset and move synchronously, so that the closed space around the spring 63 becomes larger, and since there is no inflow of external gas, a negative pressure cavity is formed around the spring 63 and in the adsorption hole 61, so that an additional adsorption constraint force is formed between the mobile phone and the charging body to enhance the combined positioning effect between the charger body 1 and the mobile phone. At this time, the internal power supply of the charger body 1 temporarily provides a wireless charging operation for the rear passengers or the co-pilot of the vehicle; When the main driver uses the improved in-vehicle mobile phone wireless charger with adsorption limit, the operator holds the fixing frame 2 and inserts the charger body 1 into the storage slot 32 from the right end opening of the storage slot 32. At this time, due to the mutual interference between the right side opening edge of the storage slot 32 and the hemispherical end of the positioning rod 64, the positioning rod 64 can be pressed into the adsorption hole 61 along the outer arc wall of the hemispherical end of the positioning rod 64, and the second piston plate 62 is pushed to compress the spring 63 simultaneously. Subsequently, after the distance between the charger body 1 and the magnetic plate 35 reaches the threshold, an attraction is generated between the charger body 1 and the magnetic plate 35, thereby pulling the magnetic plate 35 toward the charger body 1 until the limiting rod 42 passes through the circular hole 41 and the magnetic plate 35 and the inner wall of the rectangular slot 34 are in conflict with each other; It should be noted that, during the process of inserting the fixing frame 2 into the storage slot 32, when the outer arc wall of the fixing frame 2 moves to the position of the hemispherical end of the limiting rod 42, due to the mutual interference between the outer arc wall of the fixing frame 2 and the hemispherical end of the limiting rod 42, the hemispherical end of the limiting rod 42 can be directly squeezed into the circular hole 41 along the outer arc wall of the hemispherical end of the limiting rod 42, thereby leaving space for the fixing frame 2 to be inserted into the storage slot 32; During the process of the fixing frame 2 and the inner wall of the left end of the storage slot 32 approaching each other, due to the mutual interference between the fixing frame 2 and the inner wall of the storage slot 32, the charging plug 38 is just aligned with the power connection interface of the charger body 1, and after the fixing frame 2 and the inner wall of the left end of the storage slot 32 are attached, the charging plug 38 is directly inserted into the power connection interface of the charger body 1. At this time, the charger body 1 is connected to the internal power interface of the vehicle through the charging plug 38, the charging interface and the connecting line, and the charging operation of the charger body 1 is powered by the internal power supply of the vehicle; After the above-mentioned fixed frame 2 is fitted with the inner wall of the left end of the storage groove 32, the limiting rod 42 is aligned with the limiting groove 43. At this time, due to the attraction between the charger body 1 and the magnetic plate 35 pulling the magnetic plate 35, the hemispherical end of the limiting rod 42 is automatically inserted into the limiting groove 43, and then through the mutual interference between the hemispherical end of the limiting rod 42 and the inner wall of the limiting groove 43, a restraining limiting force is applied to the fixed frame 2, so that the charger body 1 is placed in the storage groove 32 more stably without being subjected to external force, and at the same time, after the fixed frame 2 is fully inserted into the storage groove 32, the positioning rod 64 is aligned with the positioning groove 69. At this time, due to the push of the spring 63 on the second piston plate 62, the hemispherical end of the positioning rod 64 is directly inserted into the positioning groove 69, so that through the mutual interference between the hemispherical end of the positioning rod 64 and the inner wall of the positioning groove 69, a restraining limiting force is applied to the fixed frame 2 to enhance the strength of the restraint between the fixed frame 2 and the baffle 31; During the movement of the magnetic plate 35 toward the charger body 1, the space between the magnetic plate 35 and the first piston plate 53 gradually expands, and since no external gas flows out of the rectangular groove 34, a relatively strong negative pressure chamber is formed in the rectangular groove 34. At this time, the negative pressure chambers in the rectangular groove 34 and the gas storage tank 51 can apply a corresponding tensile force to the adjustment plate 331 through the first piston plate 53 and the elastic rod 54, so that the adjustment plate 331 is tightly attached to the side wall of the baffle 31, so that the adjustment plate 331 can stably maintain a vertical state without being subjected to a large external force, and the charger body 1 and the baffle 31 form a complete in-vehicle mobile phone wireless charger; After the above device is assembled, the operator tilts the mobile phone to insert one side of the mobile phone from the position between the several support bars 37 between the two clamping plates 33, and then the clamping plate 33 on one side is tilted by the mutual interference between the one side of the mobile phone and the clamping plate 33, so that the mobile phone can be directly inserted between the two clamping plates 33 and the several support bars 37. Then, due to the attraction between the charger body 1 and the mobile phone, the rear side wall of the mobile phone is tightly fitted with the baffle 31 and the charger body 1, and the mobile phone is adsorbed and fixed on the baffle 31. At the same time, due to the mutual interference between the mobile phone and the support bars 37, the adjustment plate 331 and the round rod 332, the mobile phone can be simultaneously limited and constrained while being adsorbed and fixed, so that the mobile phone and the baffle 31 form a whole, so as to prevent the mobile phone from sliding off the charger body 1 when the vehicle shakes; It should be noted that when the rear side wall of the mobile phone is fitted with the baffle 31, due to the mutual interference between the rear side wall of the mobile phone and the soft ring 68, a strong friction force is generated between the rear side wall of the mobile phone and the fixed frame 2, so as to enhance the stability of the mobile phone restraint limit; It should be noted that after the above-mentioned mobile phone is adsorbed and fixed on the baffle 31, due to the mutual interference between the rear wall of the mobile phone and the positioning rod 64 and the mutual interference between the mobile phone and the round rod 332, the hemispherical end of the positioning rod 64 is stably inserted into the positioning groove 69, so that the hemispherical end of the positioning rod 64 cannot be squeezed out of the positioning groove 69, thereby locking the position between the fixed frame 2 and the baffle 31.
