Description

Technical Field

[0001] This utility model relates to the technical field of magnet adjustment mechanism, and in particular to a magnet adjustment mechanism and charging device. Background Technology

[0002] Currently, magnets are used in many devices to achieve connection based on the principle of attraction between opposite magnetic poles. For example, magnets are placed on both the charging device (such as a power bank with wireless charging capability) and the receiving wireless device (such as a mobile phone or other electronic device). The magnets on the two devices have different polarities. When the receiving wireless device approaches the charging device, the magnets on both devices attract each other perfectly, allowing the receiving wireless device to connect to the charging device. However, existing charging devices have both wireless charging and receiving functions. If the magnets in the charging device cannot be moved, the magnets on the charging device will attract the magnets on the receiving wireless device (opposite poles attract) and repel the magnets on the transmitting wireless device (like poles repel), preventing them from aligning and attracting each other, thus preventing the charging device from connecting to the charger. Summary of the Invention

[0003] This utility model provides a magnet adjustment mechanism and a charging device to solve the problem that existing charging devices have both wireless charging transmitting and receiving functions, but the magnets in the charging device cannot be moved. This causes the magnets on the charging device to attract with the magnets on the receiving wireless device (opposite poles) and repel with the magnets on the transmitting wireless device (like poles), resulting in misalignment and inability to connect the charging device to the charger.

[0004] A magnet adjustment mechanism includes a first housing and a magnet adjustment assembly; the magnet adjustment assembly includes at least two spacers and at least one first magnet. The first housing has an annular space, and at least two of the spacers are spaced apart in the annular space along the circumferential direction to form at least one movable groove; Each of the first magnets is movably mounted in the movable slot along the radial direction of the movable slot, and one of the inner and outer portions of each first magnet is designated as the N pole and the other as the S pole; When the transmitting or receiving wireless device is placed in a position corresponding to the outer portion of the first housing and the first magnet, the second magnet in the transmitting wireless device or the third magnet in the receiving wireless device mates with the outer portion of the first magnet, so that at least one of the first magnets moves from the inside to the outside in the radial direction of the corresponding movable slot.

[0005] Preferably, the magnet adjustment assembly further includes a buffer, wherein the buffer is provided on the inner sidewall and / or outer sidewall of each of the movable slots; the buffer is used to provide cushioning for the first magnet.

[0006] Preferably, the magnet adjustment assembly further includes a guide limiting structure, and each of the movable slots is provided with a guide limiting structure, which is used to guide and limit the first magnet.

[0007] Preferably, the guide limiting structure includes a matching track and a slider; one of the track and the slider is disposed radially on the inner wall of the movable groove, and the other is disposed radially on the first magnet.

[0008] Preferably, the first outer casing includes a housing and a cover; The housing has an annular groove; the cover is installed on the housing and covers the annular groove to form the annular placement space.

[0009] A charging device includes a second housing, a charging body, and the aforementioned magnet adjustment mechanism; The charging body is installed inside the second housing, and the magnet adjustment mechanism is installed inside the second housing; The first housing of the magnet adjustment mechanism is mounted on the second housing, or the first housing and the second housing of the magnet adjustment mechanism are an integral structure.

[0010] The magnet adjustment mechanism provided in this embodiment of the utility model is applied to a charging device. When the charging device has both wireless charging transmission and wireless charging reception functions, the magnet of the magnet adjustment mechanism on the charging device can be moved so that the magnet on the charging device can attract the opposite polarity of the magnet on the receiving wireless device, and can also attract the opposite polarity of the magnet on the transmitting wireless device by moving the magnet of the magnet adjustment mechanism. By adjusting the position of the magnet of the magnet adjustment mechanism, the polarity of the mating magnets can be changed, ensuring that the charging device can be connected to both receiving wireless devices (such as mobile phones and other electronic devices) and transmitting wireless devices (such as chargers), thereby improving the device's range of use.

[0017] This utility model embodiment provides a magnet adjustment mechanism, see reference. Figure 1 and Figure 2The device includes a first housing 1 and a magnet adjustment assembly 2. The magnet adjustment assembly 2 includes at least two spacers 21 and at least one first magnet 22. The first housing 1 has an annular placement space 11, and at least two spacers 21 are spaced apart along the circumferential direction of the annular placement space 11 to form at least one movable groove 3. Each first magnet 22 is movably installed in a movable groove 3 along the radial direction of the movable groove 3. One of the inner portion 221 and the outer portion 222 of each first magnet 22 is set as the N pole and the other is set as the S pole. When the transmitting wireless device or the receiving wireless device is placed in the position corresponding to the outer portion 222 of the first magnet 22 in the first housing 1, the second magnet in the transmitting wireless device or the third magnet in the receiving wireless device is connected to the outer portion 222 of the first magnet 22, so that at least one first magnet 22 moves from the inside to the outside along the radial direction of the movable groove 3 in its corresponding movable groove 3.

[0018] As an example, a magnetic adjustment mechanism is used in charging devices, such as wireless power banks, to connect a receiving or transmitting wireless device to the charging device. The magnet adjustment mechanism includes a first housing 1 and a magnet adjustment assembly 2. The magnet adjustment assembly 2 includes at least two spacers 21 and at least one first magnet 22. During installation, the first housing 1 serves as a reference, and an annular placement space 11 is provided within the first housing 1. At least two spacers 21 are spaced apart along the circumferential direction of the annular placement space 11 to form at least one movable groove 3. Then, each first magnet 22 is movably installed in a movable groove 3 along the radial direction of the movable groove 3. One of the inner portion 221 and the outer portion 222 of each first magnet 22 is designated as the N pole, and the other is designated as the S pole. With this configuration, when the transmitting or receiving wireless device is placed in the position corresponding to the outer portion 222 of the first magnet 22 on the first housing 1, the second magnet in the transmitting wireless device or the third magnet in the receiving wireless device aligns with the outer portion 222 of the first magnet 22, so that at least one first magnet 22 moves from the inside to the outside along the radial direction of the movable groove 3 within its corresponding movable groove 3. Specifically, it is assumed that each first magnet 22... The inner portion 221 of magnet 22 is the N pole, and the outer portion 222 of each first magnet 22 is the S pole. The second magnet in the transmitting wireless device is the S pole, and the third magnet in the receiving wireless device is the N pole. When the receiving wireless device is placed in the position corresponding to the outer portion 222 of the first magnet 22 in the first housing 1, the third magnet in the receiving wireless device is connected to the outer portion 222 of the first magnet 22. The two have different polarities and attract each other, so that the receiving wireless device is connected to the charging device. When the transmitting wireless device is placed in the position corresponding to the outer portion 222 of the first magnet 22 in the first housing 1, the second magnet in the transmitting wireless device is connected to the outer portion 222 of the first magnet 22. The two have the same polarity and repel each other, so that at least one first magnet 22 moves from the inside to the outside in the radial direction of its corresponding movable slot 3, so that the second magnet in the transmitting wireless device is connected to the inner portion 221 of the first magnet 22. The two have different polarities and attract each other, so that the transmitting wireless device is connected to the charging device.

[0019] In this example, the magnet adjustment mechanism is applied to a charging device. When the charging device has both wireless charging transmitting and receiving functions, the magnet of the magnet adjustment mechanism on the charging device can be moved, allowing the magnet on the charging device to attract the opposite polarity of the magnet on the receiving wireless device, and also to attract the opposite polarity of the magnet on the transmitting wireless device by moving the magnet of the magnet adjustment mechanism. By adjusting the position of the magnet of the magnet adjustment mechanism, the polarity of the mating magnets is changed, ensuring that the charging device can be connected to both receiving wireless devices (such as mobile phones and other electronic devices) and transmitting wireless devices (such as chargers), thus improving the device's usability. The spacer 21 prevents adjacent first magnets 22 from interfering with each other. The number of magnet adjustment components 2 can be selected according to actual needs; there can be one or more, with multiple magnet adjustment components 2 spaced apart along the circumferential direction of the annular placement space 11. Adjusting the width, thickness, and magnetic force of the magnets can increase the attraction force, improve connection performance, and ensure that the magnets do not detach.

[0020] In one embodiment, reference is made to Figure 1 and Figure 2 The magnet adjustment assembly 2 also includes a buffer 23, with the inner and / or outer sidewalls of each movable groove 3 provided with a buffer 23; the buffer 23 is used to provide cushioning for the first magnet 22.

[0021] As an example, the magnet adjustment assembly 2 also includes a buffer 23. During installation, the buffer 23 can be provided on the inner side wall and / or outer side wall of each movable slot 3. The buffer 23 can provide cushioning for the first magnet 22, preventing the first magnet 22 from being damaged by impact with the first housing 1, thereby improving the service life of the first magnet 22.

[0022] In one embodiment, the magnet adjustment assembly 2 further includes a guide limiting structure, and each movable slot 3 is provided with a guide limiting structure, which is used to guide and limit the first magnet 22.

[0023] As an example, the magnet adjustment assembly 2 also includes a guide limiting structure. A guide limiting structure is provided in each movable slot 3. The guide limiting structure can guide and limit the first magnet 22 to prevent the first magnet 22 from being misaligned, so that the movement of the first magnet 22 is smoother.

[0024] In one embodiment, the guide limiting structure includes an adapted track and a slider; one of the track and the slider is disposed radially on the inner wall of the movable groove 3, and the other is disposed radially on the first magnet 22.

[0025] As an example, the guide and limiting structure includes a suitable track and a slider. During installation, one of the track and slider is set on the inner wall of the movable groove 3 in the radial direction, and the other is set on the first magnet 22 in the radial direction. The slider is movably installed on the track, which can guide and limit the first magnet 22, prevent the first magnet 22 from being misaligned, and make the movement of the first magnet 22 smoother.

[0026] In one embodiment, reference is made to Figure 1 and Figure 2 The first outer casing 1 includes a housing 12 and a cover 13; the housing 12 is provided with an annular groove; the cover 13 is installed on the housing 12 and covers the annular groove to form an annular placement space 11.

[0027] As an example, the first housing 1 includes a housing 12 and a cover 13; an annular groove is provided on the housing 12. During installation, the cover 13 is installed on the housing 12 to cover the annular groove, thereby forming an annular placement space 11. This facilitates the installation of the magnet adjustment assembly 2 in the annular placement space 11, i.e., the annular groove, of the first housing 1. At the same time, the cover 13 can also provide protection for the magnet adjustment assembly 2.

[0028] This utility model provides a charging device, including a second outer shell, a charging body, and a magnet adjustment mechanism; the charging body is installed inside the second outer shell, and the magnet adjustment mechanism is installed in the second outer shell; the first outer shell 1 of the magnet adjustment mechanism is installed in the second outer shell, or the first outer shell 1 of the magnet adjustment mechanism and the second outer shell are an integral structure.

[0029] As an example, the charging device includes a second housing, a charging body, and a magnet adjustment mechanism. During installation, the charging body is installed inside the second housing, and the magnet adjustment mechanism is also installed within the second housing. This configuration allows the magnet in the magnet adjustment mechanism to move when the charging device has both wireless charging transmitting and receiving functions. This allows the magnet on the charging device to attract opposite-polarity magnets from both the receiving and transmitting wireless devices. By adjusting the position of the magnet in the magnet adjustment mechanism, the polarity of the connected magnets can be changed, ensuring that the charging device can connect to both receiving wireless devices (such as mobile phones) and transmitting wireless devices (such as chargers), thus expanding the device's usability. The charging device has two structural forms. In the first form, the first housing 1 of the magnet adjustment mechanism is a separate component. During installation, the first housing 1 of the magnet adjustment mechanism is installed inside the second housing, and the magnet adjustment assembly 2 is installed on the second housing of the charging device through the first housing 1. The second type has a first housing 1 and a second housing that are an integral structure, and the magnet adjustment component 2 is directly installed on the housing (first housing 1 and second housing) of the charging device.
