Description

Technical Field

[0001] This utility model relates to the field of magnetic bracket technology, and in particular to a magnetic connection device 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 changing the maximum magnetic attraction force of the magnetic bracket, in order to make it easier for users to separate magnetically attached devices from the magnetic bracket, related technologies use a design where the magnet can rotate, so that the magnetic attraction force of the magnet on the magnetically attached device is adjustable. However, this design causes the magnet to move as a whole, requiring a large amount of space to move, and it is difficult to precisely adjust the magnetic attraction force. Utility Model Content

[0039] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] It should be noted that if the embodiments of this utility model 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.

[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] Without changing the maximum magnetic attraction force of the magnetic bracket, in order to make it easier for users to separate magnetically attached devices from the magnetic bracket, related technologies use a design where the magnet can rotate, so that the magnetic attraction force of the magnet on the magnetically attached device is adjustable. However, this design causes the magnet to move as a whole, requiring a large amount of space to move, and it is difficult to precisely adjust the magnetic attraction force.

[0044] In view of this, see Figures 1-7This utility model provides a magnetic connection device 100, which can be used to magnetically fix any type of magnetically attachable device. The magnetically attachable device itself may be magnetic, or it may be magnetically attached by assembling magnetic accessories. Specifically, the magnetically attachable device may be a mobile phone or a tablet computer. The magnetic connection device 100 can fix the magnetically attachable device solely through magnetic attraction, or it can work in conjunction with other forces (such as supporting force, clamping force, etc.) to fix the magnetically attachable device. Depending on the actual application scenario, the magnetic connection device 100 can be fixed in different ways. For example, in a desktop environment, the magnetic connection device 100 can be placed directly on the desktop; in a vehicle environment, the magnetic connection device 100 can be fixed to the vehicle through its own clamping mechanism or magnetic attraction mechanism; in addition, the magnetic connection device 100 can also be held directly or indirectly by the user. In this case, the magnetic connection device 100 can be a bracket accessory connecting to the back of a mobile phone, or used for fixing a selfie stick to a mobile phone. Furthermore, unless otherwise specified, the relative orientational reference relationship between the magnetic connection device 100 (including any part) and the magnetically attracted device described in this utility model refers to the positional relationship under a specific posture after the magnetic connection device 100 magnetically attracts and fixes the magnetically attracted device.

[0045] Specifically, referring to the figure, the magnetic connection device 100 includes a housing assembly 110, a magnetic assembly 120, and a drive assembly 130. The housing assembly 110 has a cavity 111 and a magnetic surface 112. The magnetic surface 112 is adapted to support magnetically attracted devices. Hereinafter, the direction perpendicular to the magnetic surface 112 is defined as the first direction X, and the second direction Y is perpendicular to the first direction X. The magnetic surface 112 is located on one side of the cavity 111 along the first direction X. The cavity 111 is the inner cavity of the housing assembly 110 itself, and the magnetic surface 112 is the outer wall surface of one side of the housing assembly 110.

[0046] See Figures 1-2 Both the magnetic component 120 and the dielectric component are located in the cavity 111. The magnetic component 120 provides the magnetic attraction force for adsorbing the magnetically attachable device. Combined with the previous configuration of the housing component 110, when the user needs to magnetically fix the magnetically attachable device, the device can be placed on the magnetic surface 112. Under the magnetic attraction force of the magnetic component 120, the magnetically attachable device adheres to the magnetic surface 112, thus fixing the device to the magnetic connection device 100. It should be noted that the attachment effect described in this invention requires excluding the influence of errors and microscopic gaps.

[0047] Specifically, see Figures 1-4The magnetic component 120 includes a first magnetic part 121 and a second magnetic part 122. The driving component 130 is configured to drive the first magnetic part 121 to rotate relative to the second magnetic part 122 about a rotation axis parallel to the second direction Y, and / or to drive the second magnetic part 122 to rotate relative to the first magnetic part 121 about a rotation axis parallel to the second direction Y. It is understood that the magnetic component 120 includes two parts, the first magnetic part 121 and the second magnetic part 122, both of which can provide magnetic attraction. The appearance and structure of the first magnetic part 121 and the second magnetic part 122, as well as the magnetic attraction they can generate, may be the same or different. After the first magnetic part 121 and the second magnetic part 122 are provided, in order to achieve the purpose of adjusting the magnetic attraction, the driving component 130 can drive at least one of the first magnetic part 121 and the second magnetic part 122 to move relative to the other. Therefore, under the action of the driving component 130, on the one hand, the magnetic component 120 can be driven to rotate around a rotation axis parallel to the second direction Y, making the distance between the magnetic component 120 and the magnetic attraction surface 112 adjustable, thereby changing the magnetic attraction force; on the other hand, since the magnetic component 120 is divided into a first magnetic part 121 and a second magnetic part 122, the driving component 130 can drive the first magnetic part 121 and the second magnetic part 122 to move relative to each other, thereby reducing the rotation radius. After the rotation radius is reduced, the space required for rotation can be saved, improving the structural compactness of the magnetic connection device 100, and enabling more precise adjustment of the magnetic attraction force. For ease of explanation, the term "magnetic part" as used below refers to the first magnetic part 121 and / or the second magnetic part 122.

[0048] As can be seen, the magnetic connection device 100 of this utility model includes a housing assembly 110, a magnetic assembly 120, and a driving assembly 130. The housing assembly 110 has a cavity 111 and a magnetic surface 112. The magnetic surface 112 is adapted to support a magnetically attractable device. The direction perpendicular to the magnetic surface 112 is a first direction X, and the second direction Y is perpendicular to the first direction X. The magnetic surface 112 is located on one side of the cavity 111 along the first direction X. The magnetic assembly 120 is located in the cavity 111 and is used to provide a magnetic attraction force for attracting the magnetically attractable device. The magnetic assembly 120 includes a first magnetic part 121 and a second magnetic part 122. The driving assembly 130 is configured to drive the first magnetic part 121 to rotate relative to the second magnetic part 122 about a rotation axis parallel to the second direction Y, and / or to drive the second magnetic part 122 to rotate relative to the first magnetic part 121 about a rotation axis parallel to the second direction Y. Compared to the magnetic attraction force adjustment method in related technologies that drives the entire magnet to rotate, in the present invention, the magnetic component 120 is divided into a first magnetic part 121 and a second magnetic part 122, and the driving component 130 can drive the first magnetic part 121 and the second magnetic part 122 to move relative to each other. Therefore, the magnetic connection device 100 of the present invention has a high structural compactness and precise magnetic attraction force adjustment effect.

[0049] The following describes the specific movement of the first type of drive component 130 and magnetic component 120. (See also...) Figures 1-4 In some embodiments, the drive assembly 130 is connected to the first magnetic part 121 and the second magnetic part 122 respectively. The drive assembly 130 is configured to drive the first magnetic part 121 and the second magnetic part 122 to move synchronously, and the rotation direction of the first magnetic part 121 is opposite to the rotation direction of the second magnetic part 122. It is understood that the drive assembly 130 connects to both the first magnetic part 121 and the second magnetic part 122 and can drive them to move synchronously. This drive configuration enables high motion synchronization between the first magnetic part 121 and the second magnetic part 122 and helps to simplify the drive structure, eliminating the need for multiple drive assemblies 130.

[0050] With the drive assembly 130 synchronously driving the movement of the two magnetic parts, for more details, see... Figures 1-4In some embodiments, the magnetic component 120 further includes a first linkage 123, a second linkage 124, and a moving component 125. The two ends of the first linkage 123 are rotatably connected to the moving component 125 and the first magnetic part 121, respectively. The two ends of the second linkage 124 are rotatably connected to the moving component 125 and the second magnetic part 122, respectively. The moving component 125 is slidably connected to the housing component 110, and the drive component 130 is threadedly connected to the moving component 125 and rotatably connected to the housing component 110, so that the drive component 130 can rotate circumferentially around the first direction X and drive the moving component 125 to slide along the first direction X. The moving component 125 can drive the first linkage 123, the second linkage 124, the first magnetic part 121, and the second magnetic part 122 to rotate synchronously around a rotation axis parallel to the second direction Y. Understandably, with the above-mentioned structure and movement settings for the magnetic component 120, when the drive component 130 rotates, it can drive the moving component 125 to slide relative to the housing component 110 along the first direction X. The movement of the moving component 125 is further transmitted to the first magnetic part 121 and the second magnetic part 122 through the first linkage 123 and the second linkage 124, respectively.

[0051] To facilitate the drive assembly 130 in driving the moving part 125 to rotate via a threaded connection, see [link / reference] Figures 1-4 In some embodiments, the housing assembly 110 further includes a fixing member 113, which is located in the cavity 111 and fixedly connected to the wall surface where the magnetic suction surface 112 is located. The magnetic connection device 100 also includes a bearing 140. The drive assembly 130 has a cylindrical structure, with its outer periphery threadedly connected to the moving member 125. The inner periphery of the drive assembly 130 is sleeved on the outer periphery of the fixing member 113, and the bearing 140 is connected between the drive assembly 130 and the fixing member 113. The fixing member 113 can be integrally connected to other parts of the housing assembly 110; alternatively, the fixing member 113 can be a separate component and detachably assembled to the body of the housing assembly 110. The drive assembly 130 can be generally cylindrical. By inserting the fixing member 113 through its inner periphery and connecting the bearing 140 between them, a sliding connection can be formed between the drive assembly 130 and the housing assembly 110, resulting in high space utilization and easier user control of the drive assembly 130's rotation.

[0052] Furthermore, in some embodiments, the rotation of the drive assembly 130 can be adjusted in gears, allowing the user to perceive the degree of rotation or the magnetic force adjusted to a certain number of N. This perception can be conveyed through touch or sound, such as a ticking feedback (e.g., using a ball bearing or spring). Alternatively, the user can perceive the rotation by observing the scale markings between the housing assembly 110 and the drive assembly 130. The movement of the drive assembly 130 can be controlled manually or automatically. In the automatic mode, the magnetic connection device 100 may further include a motor, which drives the rotation of the drive assembly 130.

[0053] The following describes the specific movement of the second type of drive component 130 and magnetic component 120. (See also...) Figures 5-7 In some embodiments, the driving assembly 130 includes a first driving part 131 and a second driving part 132. The first driving part 131 is configured to drive a first magnetic part 121 to rotate relative to a second magnetic part 122 about a rotation axis parallel to the second direction Y. The second driving part 132 is configured to drive the second magnetic part 122 to rotate relative to the first magnetic part 121 about a rotation axis parallel to the second direction Y. It is understood that the first driving part 131 and the second driving part 132 can be independently controlled for rotation. The driving configuration of the first magnetic part 121 and the second magnetic part 122 allows for more precise adjustment of the magnetic attraction force and can adapt to more adjustment needs. It should be noted that in some embodiments, the first driving part 131 and the second driving part 132 can be two independent components, and this application uses such embodiments for illustration; in other embodiments, the first driving part 131 and the second driving part 132 can be two parts of a single integrated component.

[0054] For more details, see Figures 5-7In some embodiments, the first driving unit 131 includes a first gear 1311, the second driving unit 132 includes a second gear 1321, the first magnetic unit 121 includes a first rack 1211, and the second magnetic unit 122 includes a second rack 1221. The first gear 1311 meshes with the first rack 1211 so that the first driving unit 131 can drive the first magnetic unit 121, and the second gear 1321 meshes with the second rack 1221 so that the second driving unit 132 can drive the second magnetic unit 122. This arrangement enables the first driving unit 131 and the first magnetic unit 121 to form a rack and pinion drive, and the second driving unit 132 and the second magnetic unit 122 to form a rack and pinion drive. To accommodate the rotational trajectory, both the first rack 1211 and the second rack 1221 can be curved in an arc shape. In some embodiments, to drive the first gear 1311 and the second gear 1321, the first magnetic part 121 includes a first motor, and the second magnetic part 122 includes a second motor. The first motor can drive the first gear 1311 to rotate, and the second motor can drive the second gear 1321 to rotate, thereby achieving an electric drive effect. Depending on the requirements, in other embodiments, both the first gear 1311 and the second gear 1321 can be manually driven by the user.

[0055] For the specific structure of the first magnetic part 121 and the second magnetic part 122, see [link to documentation]. Figures 5-7 In some embodiments, the first magnetic part 121 includes a first mounting shell 1212 and a first magnetic element 1213. The first mounting shell 1212 has a first cavity 1214111, and the first magnetic element 1213 is accommodated within the first cavity 1214111. The second magnetic part 122 includes a second mounting shell 1222 and a second magnetic element 1223. The second mounting shell 1222 has a second cavity 1224111, and the second magnetic element 1223 is accommodated within the second cavity 1224111. Taking the configuration of the first magnetic part 121 as an example, it can be understood that the first magnetic element 1213 is the part used to generate magnetic attraction force, and the number of first magnetic elements 1213 can be one or more; the first mounting shell 1212 is used to accommodate and mount the first magnetic element 1213. The structural shape of the first mounting shell 1212 can be adapted to the first magnetic element 1213, and the structural shape of the second mounting shell 1222 can be adapted to the second magnetic element 1223. Therefore, in some embodiments, the appearance shapes of the first mounting shell 1212, the first magnetic element 1213, the second mounting shell 1222, and the second magnetic element 1223 can be the same and form a symmetrical arrangement. Specifically, in some embodiments, when viewed along the first direction X, the first mounting shell 1212 and the first magnetic element 1213 are both semi-circular, and the second mounting shell 1222 and the second magnetic element 1223 are both semi-circular, together forming a ring-shaped structure.

[0056] Based on the configuration of the first mounting shell 1212 and the second mounting shell 1222, see [reference needed]. Figures 5-7 In some embodiments, the first magnetic part 121 and the second magnetic part 122 are arranged opposite to each other along a third direction Z perpendicular to the first direction X and the second direction Y. The magnetic assembly 120 also includes a pin 126, which passes through the first mounting housing 1212 and the second mounting housing 1222 along the second direction Y to rotatably connect the first mounting housing 1212 and the second mounting housing 1222. The above arrangement allows the first mounting housing 1212 and the second mounting housing 1222 to also cooperate with the pin 126 to form a rotatable connection. More specifically, in some embodiments, along the first direction X, the first mounting shell 1212 includes a first end 12121 away from the magnetic surface 112 and a second end 12122 near the magnetic surface 112, and the second mounting shell 1222 includes a third end 12221 away from the magnetic surface 112 and a fourth end 12222 near the magnetic surface 112. The first end 12121 and the second end 12122 are two parts of the first mounting shell 1212, and the two can be two different regions on the first mounting shell 1212 as a whole. Similarly, the third end 12221 and the fourth end 12222 are two parts of the second mounting shell 1222, and the two can be two different regions on the second mounting shell 1222 as a whole. In some embodiments, the pin 126 passes through the first end 12121 and the third end 12221. Along the circumference surrounding the first direction X, the first mounting housing 1212, the first magnetic element 1213, the second mounting housing 1222, and the second magnetic element 1223 all extend in a semi-circular shape. Based on the above structural configuration, in some embodiments, the drive assembly 130 is configured to drive the magnetic assembly 120 to switch positions between a first position and a second position. See [reference needed]. Figure 5 When the magnetic assembly 120 is in the first position, the first magnetic element 1213 and the second magnetic element 1223 are parallel to one end of the first magnetic direction X near the magnetic attraction surface 112, and the second end 12122 abuts against the third end 12221. (See below) Figure 6 During the movement of the magnetic component 120 from the first position to the second position, both the first mounting housing 1212 and the second mounting housing 1222 rotate around the pin 126 towards the side away from the magnetic attraction surface 112. It can be understood that in the first position, the first mounting housing 1212 and the second mounting housing 1222 can abut against each other, thereby restricting their rotation around the pin 126 towards the side closer to the magnetic attraction surface 112. During the switch from the first position to the second position, both the first mounting housing 1212 and the second mounting housing 1222 move away from the magnetic attraction surface 112 and rotate in opposite directions, thus weakening the magnetic attraction force. See also... Figure 7In some embodiments, the driving component 130 can also drive the magnetic component 120 to a third position. During the process of the magnetic component 120 moving from the first position to the second position, the first mounting shell 1212 rotates around the pin 126 toward the side away from the magnetic attraction surface 112, and the second magnetic component 1223 is stationary relative to the shell component 110. This process only adjusts and weakens the magnetic attraction force in the area corresponding to the first magnetic component 1213, while the magnetic attraction force in the area corresponding to the second magnetic component 1223 remains unchanged.
