Description

Technical Field

[0001] This utility model relates to the field of magnetic bracket technology, and in particular to a magnetic connection component and an electronic device bracket. Background Technology

[0002] Magnetic mounts are widely used due to their ease of fixing and adjusting, especially in desktop environments, in-car environments, and for attaching selfie sticks. Existing magnetic mounts primarily rely on built-in magnets to generate magnetic force, achieving the attraction and fixation of target objects. Based on this principle, magnetic mounts can be used to fix any type of magnetically attachable device, such as mobile phones and tablets.

[0003] Without altering the magnetic attraction capability of the magnetic holder, to make it easier for users to detach magnetically attached devices from the holder, related technologies employ a method of driving the movement of magnets within the holder. This adjusts the magnetic force by changing the relative position or angle between the magnets and the attracted object. However, this method of adjusting magnetic force solely by moving the magnets within the holder has several drawbacks. Firstly, the adjustment range is limited; the magnets' movement trajectory and space are finite, preventing significant and flexible adjustments to the magnetic force, which is insufficient to meet the demands for precise and broad-based magnetic force adjustment in certain special scenarios. Secondly, the structure is complex and costly; the structures used to drive the magnets tend to occupy considerable space and increase manufacturing costs. Utility Model Content

[0009] In some embodiments, the second mating portion is configured such that when it is subjected to a circumferential driving force along a first direction, the first mating structure and the second mating structure rotate relative to each other in the circumferential direction, so that the second mating portion moves away from the first mating portion in a second direction.

[0010] In some embodiments, the magnetic connector has a connecting surface along a first direction, one side of the connecting surface is adapted to connect a magnetically absorbing device, and the other side is adapted to face a second mating structure, the first mating structure being at least partially inserted through the connecting surface.

[0011] In some embodiments, the magnetic connection device further includes a magnetic component for providing a magnetic attraction force to attract magnetically adsorbable devices. Along a first direction, a second mating portion is disposed between the housing component and the first mating portion. The side of the second mating portion facing the housing component and the side of the housing component facing the second mating portion together define a receiving cavity. The magnetic component is located in the receiving cavity. The side of the second mating portion facing the housing component has a mounting groove recessed along the first direction. The magnetic component extends at least partially into the mounting groove.

[0012] In some embodiments, along a first direction, one side of the first mating structure has a first tooth profile, and one side of the second mating structure has a second tooth profile. The first tooth profile meshes with the second tooth profile so that the first mating structure and / or the second mating structure can move relative to each other after being driven.

[0013] In some embodiments, the orthographic projection of the first tooth profile onto a projection plane perpendicular to the first direction is the first projection, and the orthographic projection of the second tooth profile onto the projection plane is the second projection. Both the first projection and the second projection extend circumferentially around the first direction.

[0014] In some embodiments, the tooth height of the first tooth profile and the tooth height of the second tooth profile are both h, and satisfy: 1mm≤h≤3mm.

[0015] In some embodiments, along the first direction, one side of the first mating structure further has a third tooth profile, and the difference between the tooth height of the first tooth profile and the tooth height of the third tooth profile is greater than or equal to 0.6 mm;

[0016] or,

[0017] Along the first direction, one side of the second mating structure also has a fourth tooth profile, and the difference between the tooth height of the second tooth profile and the tooth height of the fourth tooth profile is greater than or equal to 0.6 mm.

[0018] In some embodiments, the first mating structure and the second mating structure are configured to be circumferentially rotatable relative to each other in a direction surrounding a first direction, so that the first mating portion moves away from the second mating portion in the first direction;

[0019] Along the first direction, one side of the first mating structure has a first inclined surface, and the second mating structure can slide on the first inclined surface after being driven. The minimum angle between the first inclined surface and the magnetic attraction surface is φ1, and satisfies: 30°≤φ1≤45°.

The minimum angle between the second inclined surface and the magnetic attraction surface is φ2, and satisfies: 30°≤φ2≤45°.

[0022] A second aspect of this utility model also provides an electronic device bracket, including the magnetic connection component of any of the above embodiments.

[0023] Compared with the prior art, the beneficial effects of this application are:

[0024] The magnetic connection assembly of this application includes a magnetic connection accessory and a magnetic connection device. The magnetic connection accessory is suitable for fixing a magnetically pleasing device. The magnetic connection accessory includes a first mating part, which includes a first mating structure. The first mating structure and a second mating structure are magnetically connected. The magnetic connection device includes a second mating part and a housing assembly. The second mating part includes a second mating structure. Along a first direction, one side of the second mating structure is arranged opposite to the first mating structure, and the other side of the second mating structure faces the housing assembly. The first mating structure and / or the second mating structure can move relative to each other when driven, so that the first mating part moves away from the second mating part along the first direction. Compared to related technologies that change the magnetic force by driving the movement of magnets within the magnetic support, in the solution of this utility model, when it is necessary to remove the magnetically pleasing device, the relative movement of the first and second mating structures increases the distance between them, allowing the user to more easily separate the magnetic connection accessory and the magnetically pleasing device together. Therefore, the magnetic connection device of this utility model makes it easier and more convenient for users to separate magnetically attached devices from the magnetic connection device, and it also helps to simplify the structure and save manufacturing costs.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0046] Without altering the magnetic attraction capability of the magnetic holder, to make it easier for users to detach magnetically attached devices from the holder, related technologies employ a method of driving the movement of magnets within the holder. This adjusts the magnetic force by changing the relative position or angle between the magnets and the attracted object. However, this method of adjusting magnetic force solely by moving the magnets within the holder has several drawbacks. Firstly, the adjustment range is limited; the magnets' movement trajectory and space are finite, preventing significant and flexible adjustments to the magnetic force, which is insufficient to meet the demands for precise and broad-based magnetic force adjustment in certain special scenarios. Secondly, the structure is complex and costly; the structures used to drive the magnets tend to occupy considerable space and increase manufacturing costs.

[0047] In view of this, see Figures 1-10 This utility model provides a magnetic connection assembly 10, which includes a magnetic connection device 200 and a magnetic connection accessory 100. The magnetic connection device 200 is primarily used to magnetically attract and support a magnetically attractable device 300. The magnetic connection accessory 100 can be connected to the magnetically attractable device 300 and cooperates with the magnetic connection device 200, as detailed below. This magnetic connection assembly 10 can be used to magnetically fix any type of magnetically attractable device 300. The magnetically attractable device 300 can be magnetically fixed by assembling the magnetic connection accessory 100. Specifically, the magnetically attractable device 300 can be a mobile phone or a tablet computer. The magnetic connection assembly 10 can fix the magnetically attractable device 300 solely through magnetic attraction, or it can work in conjunction with other forces (such as supporting forces, clamping forces, etc.) to fix the magnetically attractable device 300. Depending on the actual application scenario, the magnetic connection device 200 can be fixed in different ways. For example, in a desktop environment, the magnetic connection device 200 can be placed directly on the desktop; in a vehicle environment, the magnetic connection device 200 can be fixed to the vehicle through its own clamping mechanism or magnetic attraction mechanism; in addition, the magnetic connection device 200 can also be held directly or indirectly by the user. In this case, the magnetic connection device 200 can be used as a bracket accessory for connecting to the back of a mobile phone, or for fixing a selfie stick to a mobile phone. Furthermore, unless otherwise specified, the relative orientation reference relationship between the magnetic connection component 10 (including any part) and the magnetically attracted device 300 described in this utility model corresponds to the positional relationship when the magnetic connection accessory 100 is installed on the magnetically attracted device 300, and the magnetic connection device 200 magnetically attracts and fixes the magnetic connection accessory 100, thereby indirectly magnetically fixing the magnetically attracted device 300 in a specific posture.

[0048] For details, see Figures 1-4The magnetic connection accessory 100 is suitable for fixing the magnetically oriented device 300. The magnetic connection accessory 100 can be used to fix the magnetically oriented device 300 in any suitable form, such as magnetic connection, snap-fit ​​connection, or adhesive bonding. The magnetic connection device 200 includes a second mating part 210 and a housing assembly 220 connected to each other. The second mating part 210 includes a second mating structure 211. To achieve the magnetic attraction of the second mating part 210, the magnetic connection accessory 100 includes a first mating part 110, which includes a first mating structure 111. The first mating structure 111 and the second mating structure 211 are magnetically connected. In some embodiments of the above-described magnetic connection, both the first mating structure 111 and the second mating structure 211 are magnetic materials, allowing them to directly attract each other to form a magnetic connection. In other embodiments, a magnetic element is provided on the side of the second mating structure 211 opposite to the first mating structure 111. In this case, the second mating structure 211 itself may not be magnetic. Under the magnetic force of the magnetic element, the first mating structure 111 and the second mating structure 211 adhere to each other to indirectly form a magnetic connection. Similarly, the first mating structure 111 may also have a magnetic element on the side opposite to the second mating structure 211, and have the same magnetic attraction effect as described above. It should be noted that the adhesion effect described in this utility model needs to exclude the influence of errors and micro-gap.

[0049] Specifically, see Figures 1-6 Along the first direction X, one side of the second mating structure 211 is arranged opposite to and connected to the first mating structure 111, and the other side of the second mating structure 211 faces the housing assembly 220. The first mating structure 111 and / or the second mating structure 211 can move relative to each other when driven, so that the first mating part 110 moves away from the second mating part 210 along the first direction X. It can be understood that through the relative movement between the first mating structure 111 and the second mating structure 211, the first mating part 110 can move away from the second mating part 210. Furthermore, since the magnetic connecting accessory 100 with the first mating part 110 is fixedly connected to the magnetically attracted device 300, the aforementioned movement can increase the distance between the first mating structure 111 and the second mating structure 211, thereby weakening the magnetic attraction between them. This allows the user to more easily separate the magnetic connecting accessory 100 and the magnetically attracted device 300 from the magnetic connecting device 200.

[0050] As can be seen, the magnetic connection assembly 10 of this application includes a magnetic connection accessory 100 and a magnetic connection device 200. The magnetic connection accessory 100 is suitable for fixedly connecting a magnetically attracted device 300. The magnetic connection accessory 100 includes a first mating part 110, which includes a first mating structure 111. The first mating structure 111 is magnetically connected to a second mating structure 211. The magnetic connection device 200 includes a second mating part 210 and a housing assembly 220. The second mating part 210 includes a second mating structure 211. Along the first direction X, one side of the second mating structure 211 is arranged opposite to the first mating structure 111, and the other side of the second mating structure 211 faces the housing assembly 220. The first mating structure 111 and / or the second mating structure 211 can move relative to each other after being driven, so that the first mating part 110 moves away from the second mating part 210 along the first direction X. Compared to related technologies that change the magnetic force by moving the magnets within the magnetic holder, the present invention increases the distance between the first mating structure 111 and the second mating structure 211 when the magnetically attachable device 300 needs to be removed. This allows the user to more easily separate the magnetic connector 100 from the magnetically attachable device 300 using the magnetic connection device 200. Therefore, the magnetic connection device 200 of this invention makes separating the magnetically attachable device 300 from the magnetic connection device 200 easier and more convenient, while also simplifying the structure and reducing manufacturing costs.

[0051] For the specific kinematic fit between the first mating structure 111 and the second mating structure 211, see [link to relevant documentation]. Figures 1-6 In some embodiments, the second mating portion 210 is configured such that, when subjected to a circumferential driving force along the first direction X, the first mating structure 111 and the second mating structure 211 rotate relative to each other in the circumferential direction, so that the second mating portion 210 moves away from the first mating portion 110 along the first direction. The following description uses the circumferential movement and mating configuration of the first mating structure 111 and the second mating structure 211 as an example. In other embodiments, the first mating structure 111 and the second mating structure 211 can also move relative to each other in other directions.

[0052] To reduce the impact of the first mating structure 111 on the thickness (dimension along the first direction X) of the magnetic connector 100 and to improve the tactile feel of the magnetically attached device 300 combined with the magnetic connector 100, see [reference needed]. Figures 1-3In some embodiments, the magnetic connector 100 has a connecting surface 120 along a first direction X. One side of the connecting surface 120 is adapted to connect to the magnetically attracted device 300, and the other side is adapted to face the second mating structure 211. The first mating structure 111 at least partially extends through the connecting surface 120. The first mating structure 111 and the connecting surface 120 can be separate or integrally connected. It is understood that the first mating structure 111 can be at least partially embedded in the mounting hole, thereby helping to reduce the overall thickness of the magnetic connector 100. In some embodiments, the connecting surface 120 has a mounting hole with its axis parallel to the first direction X, and the first mating structure 111 at least partially extends into the mounting hole. In this case, the first mating structure 111 and the connecting surface 120 (or other parts of the magnetic connector 100) can form a detachable connection. More specifically, in Figures 1-3 In the illustrated embodiment, the magnetically attachable device 300 is a mobile phone, the magnetic connection accessory 100 is a mobile phone case, and the first mating structure 111 is embedded in the back of the mobile phone case (i.e., the connecting surface 120). In other embodiments, the magnetically attachable device 300 is a mobile phone, and the magnetic connection accessory 100 is adapted to connect the mobile phone or the mobile phone case.

[0053] To make it easier for the magnetic connection device 200 to provide magnetic force, see Figures 1-4 In some embodiments, the magnetic connection device 200 further includes a magnetic component 230, which provides a magnetic attraction force for attracting the magnetically attracted device 300. Along the first direction X, a second mating portion 210 is disposed between the housing assembly 220 and the first mating portion 110. The side of the second mating portion 210 facing the housing assembly 220 and the side of the housing assembly 220 facing the second mating portion 210 together define a receiving cavity 240. The magnetic component 230 is located in the receiving cavity 240. The side of the second mating portion 210 facing the housing assembly 220 has a mounting groove 212 recessed along the first direction X. The magnetic component 230 extends at least partially into the mounting groove 212. With the magnetic component 230 configured as described above, when the user needs to magnetically fix the magnetically attachable device 300, the first mating structure 111 and the second mating structure 211 can come into contact along the first direction X. At this time, under the magnetic attraction of the magnetic component 230, the first mating structure 111 and the second mating structure 211 can be attracted, so that the magnetically attachable device 300 and the magnetic connecting accessory 100 can be fixed together to the magnetic connecting device 200. In addition, with the mounting groove 212 configured as described above, the structure of the second mating part 210 can be effectively used to install and position the magnetic component 230, which is beneficial to saving the space required for the installation of the magnetic component 230. Figures 1-4 In the embodiment shown, when viewed along the first direction X, both the magnetic component 230 and the mounting groove 212 are annular.

[0054] See Figures 1-4In some embodiments, the second mating part 210 further includes a mounting structure. Along the first direction X, the mounting structure is arranged opposite to the second mating structure 211. The mounting structure is connected to the housing assembly 220 and is used to adjust the relative position between the second mating part 210 and the housing assembly 220. Specifically, the adjustment of the relative position described above can involve displacing the second mating part 210 and / or the housing assembly 220 to change their relative positional relationship; or it can be achieved by rotating the second mating part 210 and / or the housing assembly 220 to change their relative orientation angle, for example, adjusting the pitch angle of the second mating part 210 relative to the ground. It is understood that the mounting structure can be used to connect the second mating part 210 to the housing assembly 220, and the mounting structure also has an adjustment function. More specifically, in some embodiments, the housing assembly 220 has a universal ball joint on the side facing the second mating part 210, and correspondingly, the mounting structure includes a ball joint mounting hole suitable for snapping on the universal ball joint, the universal ball joint is connected to the ball joint mounting hole, and the orientation of the second mating part 210 can be adjusted at multiple angles.

[0055] For the specific structural forms of the first mating structure 111 and the second mating structure 211, please refer to... Figures 1-6 In some embodiments, along the first direction X, one side of the second mating structure 211 has a first tooth profile 1111, and one side of the first mating structure 111 has a second tooth profile 2111. The first tooth profile 1111 and the second tooth profile 2111 engage so that the first mating structure 111 and / or the second mating structure 211 can move relative to each other after being driven. It is understood that when the user needs to magnetically fix the magnetically attachable device 300, the first tooth profile 1111 and the second tooth profile 2111 engage (which can be fully engaged or partially engaged). When the first mating structure 111 and / or the second mating structure 2111 are driven, the previously engaged portion of the first tooth profile 1111 and the second tooth profile 2111 no longer engages. The design of setting the parts of the first mating structure 111 and the second mating structure 211 that mate with each other as toothed structures can, on the one hand, increase the structural stability of the first mating structure 111 and the second mating structure 211 when magnetically fixing the magnetically attachable device 300, and make it easier to set their relative positions in the meshing position; on the other hand, the toothed surfaces (the oblique toothed surfaces on both sides of the tooth tip) of the toothed structure allow the first tooth 1111 and the second tooth 2111 to slide relative to each other along the toothed surface of either one, and the extension direction of the toothed surface has a component along the first direction X, so that the relative movement of the first tooth 1111 and the second tooth 2111 can cause the first mating part 110 to move away from or closer to the second mating part 210 along the first direction X.

[0056] For more specific details on the first tooth profile 1111 and the second tooth profile 2111, see [link to documentation]. Figures 1-6In some embodiments, the orthographic projection of the first tooth 1111 onto a projection plane perpendicular to the first direction X is the first projection, and the orthographic projection of the second tooth 2111 onto the projection plane is the second projection. Both the first and second projections extend circumferentially around the first direction X. In other words, the above-mentioned limitation ensures that, when viewed along the first direction X, both the first tooth 1111 and the second tooth 2111 extend circumferentially, forming a closed annular tooth structure. Specifically, it can be an annular shape of any shape, such as a circular ring or a rectangular ring. Through the above arrangement, on the one hand, the first tooth 1111 and the second tooth 2111 can form a more stable supporting force and transmission force, and on the other hand, it is easier to install and position the first tooth 1111 and the second tooth 2111. In other embodiments, the first tooth profile 1111 and / or the second tooth profile 2111 may not be in a closed ring structure. For example, the first tooth profile 1111 and the second tooth profile 2111 may both form a semi-circular arc structure or a multi-segment ring structure spaced circumferentially.

[0057] Furthermore, in order to ensure that the relative movement of the first mating structure 111 and the second mating structure 211 can effectively make the separation action of the magnetically attracted device 300 and the magnetic connection device 200 less strenuous, and to ensure that the first mating structure 111 and the second mating structure 211 do not occupy too much space, the parameters of the aforementioned tooth structure can be limited. For details, see [link to documentation]. Figures 5-6 In some embodiments, the tooth height of the first tooth profile 1111 and the tooth height of the second tooth profile 2111 are both h, and satisfy: 1mm ≤ h ≤ 3mm. For example, h can take the value of 1mm, 1.5mm, 2mm, 2.5mm, or 3mm. In some embodiments, when h = 2mm, the magnetic attraction force between the magnetic connecting device 200 and the magnetic connecting accessory 100 decreases from 25N to 5N after the first tooth profile 1111 and the second tooth profile 2111 move relative to each other to their extreme positions of distance.

[0058] To accommodate different distance adjustment or tactile feedback requirements, in some embodiments, the number of magnetic connectors 100 is multiple, and the tooth height of the second tooth profile 2111 of each magnetic connector 100 is different. The different tooth heights of each magnetic connector 100 correspond to different adjustment distances or different tactile feedbacks. When a user needs to connect a magnetic connector 100 to a magnetically actuated device 300, they can select any one of the magnetic connectors 100 for use. In other embodiments, along the first direction X, one side of the first mating structure 111 also has a third tooth profile 1112. Based on the third tooth profile 1112 defined above, in some embodiments, the difference between the tooth height of the first tooth profile 1111 and the tooth height of the third tooth profile 1112 is greater than or equal to 0.6 mm (the tooth height of the first tooth profile 1111 can be greater than the tooth height of the third tooth profile 1112, or the tooth height of the first tooth profile 1111 can be less than the tooth height of the third tooth profile 1112). This allows the tooth height between the first tooth profile 1111 and the third tooth profile 1112 to be specifically set according to different adjustment distances or different adjustment feel required (or other parameters). Similarly, the third tooth profile 1112 can also be provided on the second mating structure 211, that is, along the first direction X, one side of the second mating structure 211 also has the third tooth profile 1112, and the difference between the tooth height of the second tooth profile 2111 and the tooth height of the third tooth profile 1112 is greater than or equal to 0.6 mm. The third tooth profile 1112 provided in the second mating structure 211 can be similarly described in the above embodiment as the third tooth profile 1112 provided in the first mating structure 111, and has the same effect. It should be noted that, see... Figures 7-8 In some embodiments, the first tooth profile 1111 and the third tooth profile 1112 can be arranged alternately, so that the user can engage the second tooth profile 2111 with the first tooth profile 1111 or the third tooth profile 1112 as needed. Similarly, the second tooth profile 2111 and the fourth tooth profile 2112 can be arranged alternately, so that the user can engage the first tooth profile 1111 with the second tooth profile 2111 or the fourth tooth profile 2112 as needed. See also Figures 9-10 In other embodiments, the third tooth 1112 may be connected to the end of the first tooth 1111 away from the magnetically pleasing device 300 along the first direction X, so that the tooth height of the third tooth 1112 is greater than the tooth height of the first tooth 1111, and during the relative movement along the circumferential direction, the second tooth 2111 can sequentially mesh with the first tooth 1111 and the third tooth 1112. Similarly, the fourth tooth 2112 may be connected to the end of the second tooth 2111 close to the magnetically pleasing device 300 along the first direction X.

[0059] Based on the embodiment described above where the first mating structure 111 and the second mating structure 211 rotate relative to each other in the circumferential direction, in order to make the relative movement of the first mating structure 111 and the second mating structure 211 smoother, for the first mating structure 111, see [reference needed]. Figures 5-6 In some embodiments, along the first direction X, one side of the first mating structure 111 has a first inclined surface 1113, and the second mating structure 211 can slide on the first inclined surface 1113 after being driven. It is understood that by setting the first inclined surface 1113 and enabling the second mating structure 211 to slide on the first inclined surface 1113, the first mating part 110 can move away from or closer to the second mating part 210 along the first direction X during the sliding process, making the distance adjustment between the first mating part 110 and the second mating part 210 more convenient and smooth, and also enabling stepless adjustment. To improve the adjustment effect, in some embodiments, the minimum included angle between the first inclined surface 1113 and the magnetic attraction surface is φ1, and satisfies: 30°≤φ1≤45°. For example, φ1 can take the value of 30°, 35°, 40°, or 45°. Similarly, for the second mating structure 211, see... Figures 5-6 In some embodiments, along the first direction X, one side of the second mating structure 211 has a second inclined surface 2113. The first mating structure 111, when driven, can slide on the second inclined surface 2113. The minimum angle between the second inclined surface 2113 and the magnetic attraction surface is φ2, satisfying: 30°≤φ2≤45°. For example, φ2 can be one of 30°, 35°, 40°, or 45°. The relevant settings and effects of the second inclined surface 2113 can be referred to the above embodiments for the relevant description of the first inclined surface 1113, and will not be repeated here. In addition, in some embodiments, the first mating structure 111 or the second mating structure 211 may have a third inclined surface. The setting in the above embodiments for a tooth height difference greater than or equal to 0.6mm can be similarly applied to the height difference between the third inclined surface and the first or second inclined surface 2113, and similarly has the effect of adapting to different distance adjustment needs or adjusting the feel. See also... Figures 5-6 In conjunction with the aforementioned embodiments regarding the configuration of the first tooth profile 1111 and the second tooth profile 2111, the first inclined surface 1113 described above can correspond to the tooth surface of the first tooth profile 1111 (the inclined tooth surface located on both sides of the tooth tip), and the second inclined surface 2113 can correspond to the tooth surface of the second tooth profile 2111 (the inclined tooth surface located on both sides of the tooth tip).
