Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment chargers, in particular to a foldable wireless charger. Background Art

[0002] With the continuous advancement of technology, electronic products are becoming more and more closely integrated with our lives. Smart phones, smart watches, wireless headphones, etc. can be seen everywhere in our lives.

[0003] In the chargers of electronic products, wireless charging technology is becoming more and more mature, and wireless chargers are becoming more and more common. Wireless chargers are devices that charge based on the principle of electromagnetic induction. They are equipped with a set of coils at the sending and receiving ends. The coil at the sending end sends electromagnetic signals to the outside world under the action of electricity, and the coil at the receiving end converts the received electromagnetic signals into current, thereby achieving the purpose of wireless charging. Since wireless charging technology does not rely on power lines to transmit current when charging devices, it is becoming more and more popular among consumers.

[0004] However, in current wireless chargers, generally only a single electronic product can be wirelessly charged. However, as the number of electronic products owned by consumers gradually increases, when multiple charging devices need to be charged, the charging needs are often not met. There is also a charger on the market that can charge multiple electronic products, such as the utility model patent with announcement number CN220273349U, which provides a wireless charger that can charge multiple devices at the same time. However, the structure of the charger is relatively complex, with two horizontal parts and a slope part fixed on the main body, and charging areas are set respectively. During the process of charging the device, the charger is a fixed structure, so its angle and state are fixed when supporting the device, and cannot be adjusted, which cannot meet more usage scenarios. Moreover, when not charging, the charger is inconvenient to store because it is a fixed structure.

[0005] Therefore, there is an urgent need for a wireless charger that can adjust the charging angle and can be folded for easy storage when not charging. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation manner are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0027] The foldable wireless charger provided in this embodiment can adjust the charging angle during charging and is convenient for storage after folding. Figure 1-4 As shown, a foldable wireless charger provided in this embodiment includes a base 100 and a first support member 120 and a second support member 300 arranged on the base 100, wherein a cavity 101 for installing a circuit element 102 is opened on the base 100, one end of the first support member 120 is rotatably connected to the base 100, and a first wireless charging component electrically connected to the circuit element 102 is installed inside the first support member 120, and when the first support member 120 rotates along the rotation axis, it can be folded or unfolded on the base 100; the second support member 300 is also rotatably connected to the base 100, and a second charging component connected to the circuit element 102 is fixedly installed inside the second support member 300, and when the second support member 300 rotates along the rotation axis, the second support member 300 can be folded or unfolded on the base 100. It is worth noting that the first charging component, the second charging component and the circuit element 102 are mutually electrically connected induction coils and circuit boards, and the circuit board can provide power to different induction coils according to settings, and the specific connection method thereof belongs to mature prior art in the art, which will not be described in detail here.

[0028] When charging electronic products, such as charging a smartphone and a smart watch, the first support member 120 and the second support member 300 are transferred along the rotating axis so that the two support members are unfolded on the base 100 and remain in an open state. At this time, the smartphone and the smart watch are placed on the first support member 120 and the second support member 300 respectively, and the electronic products are wirelessly charged through the principle of electromagnetic induction; when charging is not needed, the first support member 120 and the second support member 300 are folded along the rotating axis toward the base 100 so that the two support members are overlapped on the base 100, thereby allowing the charger to shrink for easy storage.

[0029] In this embodiment, the first support member 120 is configured to have a shape that matches the top surface of the base 100. In other embodiments, the top surface of the base 100 is circular, and the first support member 120 is also configured to have a circular structure, and a support leg 210 is fixedly provided on the lower side surface above the first support member 120, and the lower end of the support leg 210 is rotatably connected to the base 100. The first support member 120 is rotatably connected to the base 100 through the support leg 210. When the first support member 120 is flipped along the rotating axis to be in an unfolded state, the surface of the first support member 120 can protrude toward the outside of the base 100, which can further change the support angle and support position of the support member for the electronic product, and can be more convenient for users to use the electronic product when charging.

[0030] It is understandable that when charging a smartphone, the user usually also uses the phone, such as watching videos, reading, etc. The first support member 120 is rotatably connected to the base 100 through the support legs 210. Therefore, after the first support member 120 is unfolded, the first support member 120 can be pushed toward the outside of the base 100, that is, toward the user, by the support legs 210, and the position and angle with the user are adjusted, thereby improving the user experience.

[0031] like Figure 2 The above is an unfolded state of a foldable wireless charger provided in this embodiment. After the first support member 120 is unfolded, due to the inclined surface molding state, in order to ensure that the electronic product does not slide along the surface when placed on the surface of the first support member 120, a placement plate 201 is further provided above the first layer. One end of the placement plate 201 is rotatably connected to the surface of the first support member 120, and can be unfolded after swinging along the rotating axis, so that when the electronic product is charged, the electronic product can be supported to prevent it from sliding downward.

[0032] In a further optimized technical solution, a window 103 is provided on the top surface of the base 100 for the support leg 210 to pass through. One end of the support leg 210 passes through the window 103 and is rotatably connected to the cavity 101. During the unfolding of the first support member 120, as the first support member 120 unfolds, the support leg 210 gradually extends out of the window 103. Similarly, when the first support member 120 is flipped along the rotating axis toward the base 100, the support leg 210 gradually passes through the window 103 and is stored in the cavity 101.

[0033] By providing a window 103 for the supporting leg 210 to pass through, when the first supporting member 120 is covered on the base 100, the supporting leg 210 can be conveniently received in the cavity 101, avoiding the need to provide a groove structure on the top of the base 100 for accommodating the supporting leg 210, thereby greatly reducing the production cost and process.

[0034] In this embodiment, if Figure 2 As described above, the axis of the support leg 210 is a curved curve, so that the window 103 can be prevented from having a large size. At the same time, when the first support member 120 is flipped along the rotation axis of the support leg 210, the extension or retraction travel radius of the support leg 210 can be made smaller.

[0035] In a further optimized technical solution, a flip plate 104 is disposed in the cavity, and the edge of the flip plate 104 is rotatably connected to the base 100 beside the window 103, such as Figure 4As shown, a bracket 1011 located next to the window 103 is fixedly arranged in the cavity, and one edge of the flip plate 104 is rotatably connected to the bracket 1011. When the flip plate 104 is flipped along the rotating axis, the window 103 can be closed in the cavity, and the support leg 210 is fixedly connected to the flip plate 104.

[0036] After the first support member 120 is unfolded, the support leg 210 extends along the window 103 and reaches the maximum unfolding angle, and the flip plate 104 closes the window 103 within the cavity, so that the cavity constitutes a closed space to prevent external dust or other contaminants from entering the cavity and affecting the operation of the circuit element 102.

[0037] In a further optimized technical solution, a raised portion is formed on the side of the flip plate 104 facing the window 103, and the raised portion has a shape and height corresponding to the window 103. The supporting leg 210 is fixedly installed on the top surface of the raised portion. After the first support member 120 is unfolded, the flip plate 104 closes the window 103 within the cavity. At the same time, the raised portion is embedded in the window 103 and fills the window 103, so that the depression formed on the surface of the base 100 due to the window 103 is filled and the surface is neat.

[0038] In this embodiment, if Figure 2-3 As shown, a first stopper 105 is also provided on the base 100 for limiting the unfolded first support member 120 to prevent it from being re-overlapped on the base 100 due to the gravity of the first support member 120 and the electronic product, wherein one end of the first stopper 105 is located beside the window 103 and is rotatably connected to the top surface of the base 100, and the first stopper 105 can rotate along the rotation axis so that the other end of the first stopper 105 can be inserted into the range of the window 103. At the same time, on the surface of the support leg 210 corresponding to the first stopper 105, a plurality of stopper grooves 211 are arranged side by side along the axial direction for the free end of the first stopper 105 to extend into. In this embodiment, the first stopper rotates along the horizontal plane, that is, the rotation axis of the first stopper is in the vertical direction. Through the above structure, the first stopper can be conveniently rotated to limit the support leg, and there is no need to set an extra avoidance space for the first stopper on the bottom plate, and the production process is simple.

[0039] When the first support member 120 is unfolded, the first limiting member 105 is rotated so that the free end of the first limiting member 105 moves toward the window 103, thereby extending the free end of the first limiting member 105 into the limiting groove 211 of the support leg 210. Since one end of the limiting member is connected to the top surface of the base 100 through a rotating shaft, the first limiting member 105 limits the swinging of the support leg 210 along the rotating shaft of the flip plate 104, so that the position of the first support member 120 is fixed. It can be imagined that a plurality of limiting grooves 211 arranged along the axis are provided on the support leg 210. Therefore, by changing the limiting grooves 211 that cooperate with the first limiting member 105, the external position of the first support member 120 in a fixed state can be adjusted to meet the usage requirements of more books.

[0040] In this embodiment, if Figure 2-3 As shown, a receiving groove 106 adapted to the second support member 300 is opened on the side of the base 100, and an opening 107 of the receiving groove 106 is located on the top surface of the base 100, wherein one end of the second support member 300 is rotatably connected to the opening 107 of the receiving groove 106, and when the second support member 300 rotates along the rotating axis, it can be accommodated in the receiving groove 106, so that the second support member 300 constitutes the side wall of the base 100, so that when the second support member 300 is not used for charging, the second support member 300 and the base 100 can be formed into a whole, which is more convenient to store.

[0041] At the same time, if Figure 2-3As shown, a second limiting member 108 for limiting the unfolded second support member 300 is also provided on the base 100, so that the second support member 300 can be kept in the unfolded state, which is convenient for placing electronic products on the surface of the second support member 300 for charging. One end of the second limiting member 108 is rotatably connected to the side wall of the receiving groove 106. At the same time, a notch 109 for accommodating the second limiting member 108 is also provided on the side wall of the receiving groove 106. When the second limiting member 108 swings along the rotation axis, the free end of the second limiting member 108 can be mutually transformed between the notch 109 and the receiving groove 106. At the same time, the rotation axis of the second limiting member 108 is set at the lower side of the rotation axis of the second support member 300. When the second support member 300 is unfolded, the second limiting member 108 is swung toward the receiving groove 106, so that The free end of the second limiting member 108 is located at the lower side of the second support plate, thereby limiting the second support plate from swinging in the direction of the receiving groove 106, so that the second support plate 300 maintains the unfolded state. It can be imagined that when the second support plate 300 needs to be accommodated in the receiving groove 106, the second limiting member 108 is flipped in the direction of the notch 109, so that the second limiting member 108 is accommodated in the notch 109, thereby releasing the restriction on the second support plate 300, so that the second support plate 300 can be flipped in the direction of the receiving groove 106 and placed in the receiving groove 106. In this embodiment, the rotation direction of the second limiting member is the same as the rotation direction of the first limiting member, and both are rotated along the horizontal plane. Similarly, the rotation axis of the second limiting member is in the vertical direction. Through the above structure, the second limiting member limits the second support member in a simple and reliable manner, and the fixing and limiting functions of the second support member can be completed without complicated operation methods.

[0042] When charging an electronic product, the circuit element 102 in the cavity 101 is connected to an external power source, so that the first wireless charging component and the second wireless charging component in the first support member 120 and the second support member 300 can be powered. When charging an electronic product, such as charging a smart phone, a smart watch, or a wireless headset, the smart phone only needs to be placed on the surface of the first support member 120 stacked on the base 100 to charge it. If the smart phone needs to be operated during charging, the first support member 120 needs to be opened to a predetermined angle and height, and after the first limit member 105 limits and fixes it, the smart phone is supported by the placement plate 201 so that it can be placed on the first support member 120 to operate the smart phone while charging. When two electronic products need to be charged at the same time, the two support members need to be unfolded at the same time and fixed by two limit members respectively, and then the two electronic products are placed on the two support members respectively to complete the charging. It is also possible to simply fold and unfold the second support member 300 to place a smart watch or wireless headphones on the second support member 300, and place the other electronic product on the first support plate stacked on the base 100.

[0043] In this embodiment, in order to support charging of three electronic devices, a third wireless charging component electrically connected to the circuit element 102 is provided inside the top surface of the base 100. After the first support member 120 and the second support member 300 are unfolded and limited, three electronic products can be charged at the same time, thereby expanding the charging position for electronic products and meeting the usage needs of more users.

Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model.
