[0039] The utility model realizes the purpose, functional characteristics and advantages, which will be further explained by combining with the embodiments and referring to the drawings. Specific implementation

[0040] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0042] In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or", or "and / or" appears in the entire text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B simultaneously satisfy the scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0043] Without changing the magnetic attraction ability of the magnetic attraction support, in order to make the action of the user separating the magnetically attractable device from the magnetic attraction support more labor-saving, in the related art, the way adopted is to drive the magnet in the magnetic attraction support to move, and the size of the magnetic force is adjusted by changing the relative position or angle between the magnet and the attracted object. However, this way of adjusting the magnetic force by only driving the magnet in the magnetic attraction support to move has many deficiencies. On the one hand, the adjustment range is limited, the movement trajectory and space of the magnet are limited, which leads to the fact that the magnetic force cannot be flexibly adjusted by a large margin, and it is difficult to meet the demand for precise and extensive adjustment of the magnetic force in some special scenarios; on the other hand, the structure is complex and the cost is high, in order to realize the precise movement of the magnet, an additional driving mechanism and a complex mechanical transmission device need to be provided, which not only increases the manufacturing cost, but also reduces the overall reliability, and the magnetic force adjustment function is easily affected by mechanical failure.

[0044] In view of this, referring to Figures 1-10The embodiment of the utility model provides a kind of magnetic connecting device 100, the magnetic connecting device 100 can be used for magnetically attracting and fixing arbitrary type of magnetically attractable equipment 200, the magnetically attractable equipment 200 itself can have magnetism, or by assembling magnetic accessory to enable it to be magnetically attracted and fixed, magnetically attractable equipment 200 specifically can be mobile phone or tablet computer.Magnetic connecting device 100 can only rely on the action of magnetic attraction to fix magnetically attractable equipment 200, it can also act together with other forces (for example, supporting force, clamping force etc.) to fix magnetically attractable equipment 200.According to actual application scene, magnetic connecting device 100 itself can adopt different forms to fix, for example, in desktop environment, magnetic connecting device 100 can be placed directly on desktop;In vehicle environment, magnetic connecting device 100 can be fixed on vehicle by its own clamping mechanism or magnetic attraction mechanism;In addition, magnetic connecting device 100 can be directly or indirectly held by user, and the magnetic connecting device 100 at this time can be the support accessory connected to the back of mobile phone, or be used for the fixed connection of selfie stick and mobile phone.In addition, the relative orientation reference relationship between the magnetic connecting device 100 (including any part) described in the utility model and the magnetically attractable equipment 200, if no special description, is the positional relationship in the specific attitude after magnetically attractable equipment 200 is magnetically attracted and fixed by magnetic connecting device 100.

[0045] Specifically, refer to Figure 1 、 Figure 8 And Figure 10 , magnetic connecting device 100 includes shell assembly 110, magnetic assembly 120 and guide assembly 130.Shell assembly 110 has accommodating cavity 111, and shell assembly 110 includes magnetic attraction surface 112 suitable for bearing magnetically attractable equipment 200, and magnetic attraction surface 112 is located at the side of accommodating cavity 111.Among them, accommodating cavity 111 is the inner cavity of shell assembly 110 itself, and magnetic attraction surface 112 is the outer wall surface of one side of shell assembly 110.

[0046] Refer to Figure 10 , magnetic assembly 120 is located in accommodating cavity 111, and magnetic assembly 120 is used to provide the magnetic attraction force of attracting magnetically attractable equipment 200.Combined with the setting of shell assembly 110 before, when user needs to magnetically attract and fix magnetically attractable equipment 200, magnetically attractable equipment 200 can be placed on magnetic attraction surface 112, and at this time, under the action of the magnetic attraction force of magnetic assembly 120, magnetically attractable equipment 200 is attached to magnetic attraction surface 112, so that magnetically attractable equipment 200 can be fixed on magnetic connecting device 100.It needs to be explained that the attachment effect explained in the utility model needs to exclude the influence of error and micro gap.

[0047] Particularly, refer to Figures 1-8The guiding assembly 130 comprises a first guide 131 having a first guiding surface 1311 with opposite first end 13111 and second end 13112, the first end 13111 is connected with the magnetic attraction surface 112, and the first guiding surface 1311 gradually extends away from the magnetic attraction surface 112 along the direction from the first end 13111 to the second end 13112. With the above-mentioned first guide 131, in the initial fixed state (i.e. when it is necessary to stably fix the magnetically-attractable device 200), the magnetically-attractable device 200 is magnetically attached to the magnetic attraction surface 112, at this time the first guide 131 can be spaced apart from the magnetically-attractable device 200 or can be in abutment with the magnetically-attractable device 200; when it is necessary to remove the magnetically-attractable device 200, an external driving force parallel to the magnetic attraction surface 112 can be applied to the magnetically-attractable device 200, so that the magnetically-attractable device 200 can slide on the first guiding surface 1311 relative to the magnetic connection device 100, in the process of sliding, since the first guiding surface 1311 gradually extends away from the magnetic attraction surface 112 along the sliding direction, the part of the magnetically-attractable device 200 in contact with the first guiding surface 1311 also gradually extends away from the magnetic attraction surface 112, and thus at least part of the magnetically-attractable device 200 is no longer attached to the magnetic attraction surface 112, and the magnetic attraction force of the magnetic assembly 120 to the magnetically-attractable device 200 is weakened. In the above-mentioned movement process, since the first guide 131 plays a guiding role (hereinafter referred to as a separation guiding role) for the magnetically-attractable device 200 to separate from the magnetic attraction surface 112, the user can more easily separate the magnetically-attractable device 200 from the magnetic attraction surface 112. It should be noted that in some embodiments, the separation assembly can completely separate the magnetically-attractable device 200 from the magnetic attraction surface 112, and in other embodiments, the separation assembly can separate part of the magnetically-attractable device 200 from the magnetic attraction surface 112, and another part of the magnetically-attractable device 200 still contacts the magnetic attraction surface 112.

[0048] It can be seen that the magnetic connection device 100 of the utility model includes a shell assembly 110, a magnetic assembly 120 and a guide assembly 130. The shell assembly 110 has a containing cavity 111, and the shell assembly 110 includes a magnetic attraction surface 112 adapted to carry a magnetically attractable device 200, and the magnetic attraction surface 112 is located at one side of the containing cavity 111. The magnetic assembly 120 is located in the containing cavity 111, and the magnetic assembly 120 is used for providing a magnetic attraction force for attracting the magnetically attractable device 200. In particular, in order to make the magnetically attractable device 200 more easily removed from the magnetic connection device 100, the first guide piece 131 of the guide assembly 130 has a first guide surface 1311, and the first guide surface 1311 has opposite first and second ends 13111 and 13112, the first end 13111 is connected to the magnetic attraction surface 112, and in the direction from the first end 13111 to the second end 13112, the first guide surface 1311 gradually extends away from the magnetic attraction surface 112. Compared with the design of the prior art which changes the magnetic force by driving the magnet in the magnetic attraction bracket to move, in the scheme of the utility model, when the magnetically attractable device 200 needs to be removed, an external driving force parallel to the magnetic attraction surface 112 can be applied to the magnetically attractable device 200, so that the magnetically attractable device 200 can slide on the first guide surface 1311 relative to the magnetic connection device 100, and during the sliding process, at least part of the magnetically attractable device 200 gradually moves away from the magnetic attraction surface 112. Thus, the magnetic connection device 100 of the utility model makes the action of separating the magnetically attractable device 200 from the magnetic connection device 100 more labor-saving and more convenient to operate, and is beneficial to simplifying the structure and saving manufacturing costs.

[0049] For the specific structural arrangement of the first guide piece 131, see Figures 1-7 In the first structural arrangement, the structure of the first guide piece 131 is wedge-shaped, at this time the first guide piece 131 has a block structure, and has a flat inclined surface arranged obliquely relative to the magnetic attraction surface 112, and the inclined surface is the first guide surface 1311. In the second structural arrangement, the structure of the first guide piece 131 is spherical, and at this time the first guide surface 1311 is the outer peripheral surface of the spherical guide assembly 130. It should be noted that the spherical shape described above includes a regular spherical body and an irregular spherical body (hemispherical body, ellipsoidal body, etc.). In the third structural arrangement, the first guide piece 131 is a rotary body (at this time the structure of the first guide piece 131 can be a spherical body, a cylindrical body, etc.), so that the first guide piece 131 is configured to be able to rotate along an axis parallel to the magnetic attraction surface 112, thereby facilitating the sliding of the magnetically attractable device 200 along the rolling first guide piece 131 and reducing the friction. The specific structural arrangement of the second guide piece 132 can refer to the above-described various structural arrangements of the first guide piece 131, and will not be described here.

[0050] It should be noted that the external driving force for driving the magnetically attractable device 200 can be directly or indirectly provided by a user, or provided by a driving member of the magnetic connecting device 100 or other devices. The driving member can include a motor, an electric cylinder, a pneumatic cylinder, etc. Specifically, in some embodiments, the magnetic connecting device 100 further includes a driving assembly connected to the housing assembly 110, and the driving assembly is configured to move in a direction close to the guiding assembly 130 after being driven, so that the magnetically attractable device 200 contacts the guiding assembly 130, and the guiding assembly 130 plays a role of separating and guiding.

[0051] The direction perpendicular to the magnetic attraction surface 112 is defined as the first direction X, and the magnetic attraction surface 112 includes a magnetic attraction area 1121 opposite to the magnetic assembly 120 along the first direction X. According to the above definition, the magnetic attraction area 1121 is a part of the wall surface of the magnetic attraction surface 112, and is suitable for being attached to the magnetically attractable device 200 under the magnetic force of the magnetic assembly 120. In order to make the separation effect of the magnetically attractable device 200 from the magnetic attraction surface 112 better, further, see Figures 1-8 In one type of scheme, the magnetic connecting device 100 further includes a second guiding member 132, and the second guiding member 132 has a second guiding surface 1321 with a third end 13211 opposite to a fourth end 13212. The third end 13211 is connected to the magnetic attraction surface 112, and the second guiding surface 1321 gradually extends away from the magnetic attraction surface 112 in a direction from the third end 13211 to the fourth end 13212. The first guiding member 131 and the second guiding member 132 are respectively connected to two sides of the magnetic attraction area 1121, so that the first end 13111 and the third end 13211 are suitable for respectively facing two sides of the magnetically attractable device 200. It can be understood that the structure and arrangement of the second guiding member 132 are similar to those of the first guiding member 131, and the main difference is that the first guiding member 131 and the second guiding member 132 are respectively used for facing the opposite two sides of the magnetically attractable device 200. In specific embodiments, the magnetically attractable device 200 is a mobile phone, and the first guiding member 131 and the second guiding member 132 can respectively face the long sides of the left and right sides of the mobile phone.

[0052] According to the above relative arrangement of the first guiding member 131 and the second guiding member 132, see Figures 1-7In some embodiments, after the external driving force is applied to the magnetically attractable device 200, the first guide 131 and the second guide 132 can simultaneously contact opposite sides of the magnetically attractable device 200, and the opposite sides of the magnetically attractable device 200 can slide on the first guide surface 1311 and the second guide surface 1321 respectively, in which process, the opposite sides of the magnetically attractable device 200 are simultaneously away from the magnetic attraction surface 112; in other embodiments, the movement of the magnetically attractable device 200 in one direction can only slide along the first guide surface 1311, and the movement of the magnetically attractable device 200 in another direction can only slide along the second guide surface 1321, that is, the first guide 131 and the second guide 132 are respectively responsible for the separation action when the magnetically attractable device 200 moves in different directions.

[0053] For more specific arrangements of the first guide 131 and the second guide 132, see Figures 1-8 In some embodiments, the first guide 131 and the second guide 132 are oppositely arranged along the diagonal direction of the magnetic attraction surface 112, the first guide surface 1311 has a first side edge 13113 connecting the first end 13111 and the second end 13112, and the second guide surface 1321 has a second side edge 13213 connecting the third end 13211 and the fourth end 13212. Specifically, in the embodiment shown in the figure, the first guide 131 and the second guide 132 are both wedge-shaped blocks, at this time, the first guide 131 has two opposite and parallel first side edges 13113, and the second guide 132 has two opposite and parallel second side edges 13213. Figures 1-8 In some embodiments, the first side edge 13113 and the second side edge 13213 are arranged in central symmetry with respect to the geometric center of the magnetic attraction area 1121. By the above arrangement, after the magnetically attractable device 200 is placed between the first guide 131 and the second guide 132 and rotated, the oppositely arranged first guide surface 1311 and second guide surface 1321 can respectively contact the two sides of the magnetically attractable device 200 along the diagonal direction, and in the process of rotation, the two sides of the magnetically attractable device 200 along the diagonal direction can respectively slide on the first guide surface 1311 and the second guide surface 1321. Therefore, the first guide 131 and the second guide 132 under the above arrangement can jointly play a separation guiding role on the magnetically attractable device 200, and each of them is responsible for the two sides of the magnetically attractable device 200 along the diagonal direction, so that the effect of the separation guiding role is better.

[0054] In order to prevent the magnetically attractable device 200 from slipping and scratching, in some embodiments, the material of the guide assembly 130 and / or the magnetic attraction surface 112 (specifically, the part of the magnetic attraction surface 112 adapted to contact the magnetically attractable device 200) can be a flexible material. In addition, see Figures 8-10In some embodiments, the housing assembly 110 comprises a housing body 113 and a movable housing 114 located at one side of the accommodating cavity 111, and the magnetic attraction area 1121 is located at the side of the movable housing 114 which is adapted to face the magnetically attractable device 200, and the movable housing 114 is configured to be movable relative to the housing body 113 in a direction approaching the guiding assembly 130. In some embodiments, the common movement of the driving assembly and the movable housing 114 is formed by direct connection of the two, i.e. the movement of the driving assembly can directly drive the movable housing 114; in other embodiments, the common movement of the driving assembly and the movable housing 114 is formed by indirect movement of the two, for example, due to the magnetically attractable device 200 being supported at one side of the movable housing 114, so that the driving assembly drives the magnetically attractable device 200 at the same time, and the magnetically attractable device 200 drives the movable housing 114 to move. Through the arrangement of the movable housing 114, in the process of being acted on by the driving force, the movable housing 114 can maintain the original magnetic attraction state in the initial stage and move with the magnetically attractable device 200, and with the further action of the driving force and the guiding assembly 130, the magnetically attractable device 200 can completely or substantially separate from the magnetic attraction of the magnetic assembly 120. In the above action process, since the magnetically attractable device 200 will not suddenly slide with the magnetic attraction surface 112 under the initial external driving force, but gradually slide to realize smooth transition separation, the damage of the magnetically attractable device 200 or the wear of the magnetic attraction surface 112 caused by instantaneous sliding is effectively avoided.

[0055] For specific movement arrangement of the movable housing 114, see Figures 8-10In some embodiments, the movable shell 114 is configured to rotate relative to the shell body 113 along the direction of the normal line of the magnetic attraction surface 112. In this case, the guide assembly 130 can include the first guide 131 and the second guide 132 as described in the foregoing embodiments. In order to facilitate the rotation of the movable shell 114, in some embodiments, the shell body 113 is adapted to have a rotation opening 1131 on the side facing the magnetically attractable device 200, one end of the movable shell 114 is located in the accommodating cavity 111 and rotationally connected to the shell body 113, and the other end extends out of the shell body 113 through the rotation opening 1131. In the above arrangement, the movable shell 114 is rotationally arranged in the shell body 113, and the movable shell 114 can be located between the first guide 131 and the second guide 132, so that the arrangement of the movable shell 114 is more reasonable and easier to rotate following the rotation of the magnetically attractable device 200. Further, in order to prevent the magnetically attractable device 200 from contacting the shell body 113 during the movement of the magnetically attractable device 200 and the movable shell 114 together, the size of the movable shell 114 protruding out of the shell body 113 should not be too small, and in order to enable the guide assembly 130 to still play a better separation guiding role on the magnetically attractable device 200 after the magnetically attractable device 200 is supported on the protruding movable shell 114, the size of the movable shell 114 protruding out of the shell body 113 should not be too large (on the contrary, if the size is too large, the magnetically attractable device 200 is more difficult to contact the guide assembly 130). Therefore, in some embodiments, the size of the movable shell 114 protruding out of the shell body 113 along the first direction X is L, and satisfies: 0.3mm≤L≤0.6mm. Exemplarily, L can take one of 0.3mm, 0.4mm, 0.5mm, and 0.6mm.

[0056] Based on the above arrangement of the movable shell 114, in order to make the movement of the movable shell 114 more flexible, referring to Figures 9-10 In some embodiments, the shell assembly 110 further includes a supporting spring 115, one end of the supporting spring 115 is connected to the shell body 113 along the first direction X, and the other end is connected to the movable shell 114. The arrangement of the supporting spring 115 can not hinder the rotation of the movable shell 114, but provide the movable shell 114 with an elastic movement allowance along the first direction X, so that the movement of the movable shell 114 is more flexible. In addition, in order to facilitate the rotation of the movable shell 114, referring to Figures 9-10In some embodiments, the shell assembly 110 further comprises a bushing 116 sleeved outside the movable shell 114 and connected between the shell body 113 and the movable shell 114. The shell assembly 110 further comprises a bushing 116 sleeved outside the movable shell 114 and connected between the shell body 113 and the movable shell 114. It can be understood that the bushing 116 can reduce the friction between the movable shell 114 and the shell body 113 during relative rotation, and thus the material of the bushing 116 can be a wear-resistant material, such as one of copper, stainless steel, and nylon. In other embodiments, other parts suitable for reducing friction, such as bearings, can also be provided between the movable shell 114 and the shell body 113.

[0057] Unlike the scheme of providing the first guide 131 and the second guide 132 on both sides of the magnetically attractable device 200, in another type of scheme, the guide assembly 130 is only located on one side of the magnetic attraction area 1121 in a direction parallel to the magnetic attraction surface 112, and based on this, when the magnetically attractable device 200 needs to be removed, a pushing force towards the first guide 131 can be applied to the magnetically attractable device 200 from the other side of the magnetic attraction area 1121 (the pushing force can be manually applied by a user or applied by a driving device additionally provided), so as to drive the magnetically attractable device 200 to slide on the first guide surface 1311.

[0058] In order to further ensure the separation guiding effect of the guide assembly 130, in some embodiments, the minimum distance of the first guide surface 1311 to the magnetic attraction surface 112 in the first direction X is L, and satisfies: 2mm≤L≤4mm. For example, L can take one of 2mm, 3mm, and 4mm. The value of L is the distance by which the magnetically attractable device 200 can move away from the magnetic attraction surface 112 in the first direction X, and by limiting the size of L as described above, the structure of the guide assembly 130 can be simplified, and the guide assembly 130 can ensure a better separation guiding effect. In some embodiments, the size limitation of L can make the magnetic attraction force between the magnetic attraction surface 112 and the mobile phone decrease by 10N~20N after the magnetically attractable device 200 slides to the limit position away from the magnetic attraction surface 112 on the first guide surface 1311. When the second guide 132 is provided, the minimum distance of the first guide surface 1311 to the magnetic attraction surface 112 in the first direction X can also satisfy the range limitation of the size of L as described above.
