[0048] Without changing the magnetic attraction capability 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 shortcomings. On the one hand, the adjustment range is limited, the movement trajectory and space of the magnet are limited, which results in 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, and the structure used to drive the magnet to move in the related art easily occupies a large space and increases the manufacturing cost.
[0049] 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, the magnetically attractable equipment itself can have magnetism, or by assembling magnetic accessory to enable it to be magnetically attracted and fixed, and the magnetically attractable equipment can be specifically mobile phone or tablet computer.Magnetic connecting device 100 can be fixed only by the action of magnetic attraction force, and can also be fixed by acting together with other forces (such as supporting force, clamping force, etc.).According to actual application scene, magnetic connecting device 100 itself can be fixed in different forms, for example, in desktop environment, magnetic connecting device 100 can be placed directly on the desktop;In the car environment, magnetic connecting device 100 can be fixed on the vehicle by its own clamping mechanism or magnetic attraction mechanism;In addition, magnetic connecting device 100 can also be directly or indirectly held by the user, and at this time, magnetic connecting device 100 can be a support accessory connected to the back of the mobile phone, or be used for the fixed connection between selfie stick and mobile phone.In addition, the relative orientation reference relationship between magnetic connecting device 100 (including any part) and the magnetically attractable equipment described in the utility model, unless otherwise specified, is the positional relationship in the specific attitude after the magnetically attractable equipment is magnetically attracted and fixed by magnetic connecting device 100.
[0050] Specifically, referring to Figures 1-4 Magnetic connecting device 100 includes first matching part 110 and second matching part 120.First matching part 110 is provided with first matching structure 111 on one side and magnetic attraction surface 112 on the other side.Corresponding to first matching part 110, second matching part 120 includes housing assembly 121, magnetic assembly 122 and second matching structure 123.Housing assembly 121 has accommodating cavity 1211, magnetic assembly 122 is located in accommodating cavity 1211, magnetic assembly 122 is used for providing magnetic attraction force for attracting magnetically attractable equipment, and second matching structure 123 is movably connected to first matching structure 111.Among them, accommodating cavity 1211 is the inner cavity of housing assembly 121 itself, magnetic attraction surface 112 is the outer wall surface of one side of first matching part 110, and is suitable for bearing magnetically attractable equipment.When the user needs to magnetically attract and fix the magnetically attractable equipment, the magnetically attractable equipment can be placed on the magnetic attraction surface 112, and at this time, under the action of the magnetic attraction force of the magnetic assembly 122, the magnetically attractable equipment is attached to the magnetic attraction surface 112, so that the magnetically attractable equipment can be fixed on the magnetic connecting device 100.It should be noted that the attachment effect described in the utility model needs to exclude the influence of error and micro gap.
[0051] Referring to Figures 1-6, based on the first cooperating structure 111 and the second cooperating structure 123, the direction perpendicular to the magnetic surface 112 is defined as the first direction X. In particular, along the first direction X, the first cooperating structure 111 is arranged opposite to the magnetic surface 112, and one side of the magnetic surface 112 is adapted to carry the magnetically attractable device, and the other side faces the accommodating cavity 1211. The first cooperating structure 111 and / or the second cooperating structure 123 can be driven to move relatively, so as to drive the first cooperating part 110 to move away from the second cooperating part 120 along the first direction X. It can be understood that, through the relative movement between the first cooperating structure 111 and the second cooperating structure 123, the first cooperating part 110 can be driven to move away from the second cooperating part 120 along the first direction X. Since the magnetic surface 112 of the first cooperating part 110 is adapted to carry the magnetically attractable device, and the magnetic assembly 122 is located in the accommodating cavity 1211 of the second cooperating part 120, the movement can increase the distance between the magnetically attractable device and the magnetic assembly 122, so that the user can separate the magnetically attractable device from the magnetic surface 112 more easily.
[0052] It should be noted that, for the above movement arrangement, one of the first cooperating structure 111 and the second cooperating structure 123 can be movably arranged, and the other can be fixedly arranged; or both the first cooperating structure 111 and the second cooperating structure 123 can be movably arranged. In addition, the external driving force for driving the first cooperating structure 111 and the second cooperating structure 123 to move relatively can be directly or indirectly provided by the user, or can be provided by the driving member of the magnetic connection device 100 or other devices.
[0053] It can be seen that the magnetic connection device 100 of the present application comprises a first fitting part 110 and a second fitting part 120. The first fitting part 110 is provided with a first fitting structure 111 on one side and a magnetic attraction surface 112 on the other side. The second fitting part 120 comprises a shell assembly 121, a magnetic assembly 122 and a second fitting structure 123. The shell assembly 121 has a receiving cavity 1211, and the magnetic assembly 122 is located in the receiving cavity 1211. The magnetic assembly 122 is used to provide a magnetic attraction force for attracting a magnetically attractable device. The second fitting structure 123 is movably connected to the first fitting structure 111. The direction perpendicular to the magnetic attraction surface 112 is the first direction X. Along the first direction X, the first fitting structure 111 is arranged opposite to the magnetic attraction surface 112. One side of the magnetic attraction surface 112 is adapted to carry the magnetically attractable device, and the other side faces the receiving cavity 1211. The first fitting structure 111 and / or the second fitting structure 123 can move relatively after being driven, so that the first fitting part 110 moves away from the second fitting part 120 along the first direction X. Compared with the related art design of changing the magnetic force by driving the movement of the magnet in the magnetic attraction bracket, in the present application, when the magnetically attractable device needs to be removed, the relative movement of the first fitting structure 111 and the second fitting structure 123 can increase the distance between the magnetically attractable device and the magnetic assembly 122, so that the user can separate the magnetically attractable device from the magnetic attraction surface 112 more easily. Thus, the magnetic connection device 100 of the present application makes the action of the user separating the magnetically attractable device from the magnetic connection device 100 more labor-saving and more convenient to operate, and is beneficial to simplifying the structure and saving the manufacturing cost.
[0054] For the specific movement cooperation form between the first fitting structure 111 and the second fitting structure 123, see Figures 1-6 In some embodiments, the first fitting structure 111 and the second fitting structure 123 are configured to be able to rotate relatively along the circumferential direction around the first direction X. The second fitting structure 123 is slidably connected to the shell assembly 121 along the circumferential direction around the first direction X. More specifically, see Figures 1-4 In some embodiments, the second fitting structure 123 is at least partially located in the receiving cavity 1211, and one side of the shell assembly 121 has an opening communicating with the receiving cavity 1211. At this time, the second fitting structure 123 can partially protrude out of the receiving cavity 1211 or be entirely located in the receiving cavity 1211. In other embodiments, the second fitting structure 123 can be independently provided relative to the shell assembly 121 and the magnetic assembly 122. At this time, the second fitting structure 123 can be arranged between the shell assembly 121 and the first fitting structure 111 along the first direction X. The following is described based on the above-mentioned movement cooperation form of the first fitting structure 111 and the second fitting structure 123 along the circumferential direction. In other embodiments, the first fitting structure 111 and the second fitting structure 123 can also move relatively along other directions.
[0055] For more convenient control of the relative movement of the first cooperating structure 111 and the second cooperating structure 123, see Figures 1-4 In some embodiments, the second cooperating part 120 further comprises an operating member 124, which can be directly driven by the user, and is configured to drive the second cooperating structure 123 to move circumferentially relative to the first cooperating structure 111 after being driven. The driving action on the operating member 124 can be any type of operation such as dialing, pulling, pressing, etc. More specifically, corresponding to the movement form of the relative rotation of the first cooperating structure 111 and the second cooperating structure 123, in some embodiments, the housing assembly 121 has a first through hole 1212, the operating member 124 is connected to the second cooperating structure 123 and passes through the first through hole 1212, one end of the operating member 124 is fixedly connected to the second cooperating structure 123 in the accommodating cavity 1211, and the other end extends out of the accommodating cavity 1211 through the first through hole 1212, and the first through hole 1212 extends circumferentially to enable the operating member 124 to move circumferentially after being driven. Through the above-mentioned first through hole 1212 and the operating member 124, when it is necessary to move the first cooperating structure 111 and the second cooperating structure 123 relative to each other, the user applies a circumferential force to the operating member 124, so that the second cooperating part 120 connected to the operating member 124 can move circumferentially relative to the first cooperating part 110. The driving form of the operating member 124 driving the second cooperating part 120 to rotate circumferentially can be direct driving or indirect driving, see Figures 1-4 When the operating member 124 is directly driven, the operating member 124 is directly connected to and drives the second cooperating part 120 to move; when the operating member 124 is indirectly driven, a transmission mechanism can be arranged between the operating member 124 and the second cooperating part 120. By arranging various transmission mechanisms between the operating member 124 and the second cooperating part 120, the driving stroke of the operating member 124 to the second cooperating part 120 can be longer under a certain operating stroke, or the operation of the operating member 124 can be more labor-saving under a certain operating stroke, or the operating stroke of the operating member 124 can be shorter under a certain driving stroke of the second cooperating part 120. Specifically, the transmission mechanism can be a ratchet mechanism, which includes a ratchet wheel and a pawl. At this time, the operating member 124 can act as the pawl, or the operating member 124 can drive the pawl to move; the ratchet wheel can be the second cooperating part 120, or the ratchet wheel can drive the second cooperating part 120 to rotate, and at this time, the arrangement of the ratchet mechanism can increase the adjustment range of the operating member 124 driving the second cooperating part 120, that is, the driving stroke of the operating member 124 to the second cooperating part 120 can be longer under a certain operating stroke. Similarly, in other embodiments, the operating member 124 can be arranged on the first cooperating part 110, so that the user can apply a circumferential force to the operating member 124, so that the first cooperating part 110 connected to the operating member 124 can move circumferentially relative to the second cooperating part 120.
[0056] In order to make the position setting of each component of the magnetic connecting device 100 more compact and reasonable, referring to Figures 1-4 In some embodiments, the second matching structure 123 extends in a ring shape (which can be any ring shape, such as a circular ring, a rectangular ring, etc.), the magnetic assembly 122 includes a magnetic piece 1221 and a shell 1222, the magnetic piece 1221 is located inside the shell 1222, the shell assembly 121 has an inner circumferential wall 1213, the shell 1222 has an outer circumferential wall 12222, along a direction perpendicular to the first direction X, the inner circumferential wall 1213 faces one side of the accommodating cavity 1211, the outer circumferential wall 12222 faces the other side of the accommodating cavity 1211, and the second matching structure 123 is accommodated between the inner circumferential wall 1213 and the outer circumferential wall 12222. It can be understood that the outer circumferential wall 12222 of the shell 1222 and the inner circumferential wall 1213 of the shell assembly 121 jointly form a space for accommodating the second matching structure 123, so that the second matching structure 123, the shell assembly 121 and the magnetic assembly 122 are fixedly connected, and the space for accommodating the second matching structure 123 is part of the accommodating cavity 1211, and the magnetic assembly 122 is arranged on the inner side of the second matching structure 123. Compared with the design of directly arranging the second matching structure 123 on one side of the shell assembly 121, the above arrangement can save the space required for installing the second matching structure 123, and the shell assembly 121 and the magnetic assembly 122 can be used to jointly position and install the second matching structure 123.
[0057] Based on the above description of the first matching structure 111 and the second matching structure 123 rotating relative to each other in the circumferential direction, and the second matching structure 123 being slidingly connected to the shell assembly 121, in order to guide and limit the movement of the first matching part 110, referring to Figures 3-4In some embodiments, the housing assembly 121 has a second through hole 1214, an axis of the second through hole 1214 is parallel to the first direction X, the first fitting part 110 further comprises a guide column 113, one end of the guide column 113 is fixedly connected to a side of the first fitting part 110 close to the second fitting part 120 along the first direction X, the other end of the guide column 113 is arranged through the second through hole 1214 and can abut against the housing assembly 121, so that the second fitting structure 123 is driven, the guide column 113 moves in the second through hole 1214 along the first direction X. Through the above-mentioned arrangement of the guide column 113 and the second through hole 1214, the second fitting structure 123 can be driven to rotate along the circumferential direction, and the cooperation of the guide column 113 and the second through hole 1214 limits the rotation of the first fitting part 110 along the circumferential direction, so that the rotation of the second fitting part 120 further drives the first fitting part 110 to move away from the second fitting part 120 along the first direction X. When the guide column 113 abuts against the housing assembly 121, the first fitting part 110 has moved to the limit position away from the second fitting part 120. The abutting action of the guide column 113 can be that the guide column 113 in the accommodating cavity 1211 abuts against the inner side of the top wall of the housing assembly 121, and the top wall is arranged on one side of the housing assembly 121 and faces the accommodating cavity 1211 along the first direction X. Thus, the guide column 113 and the second through hole 1214 play a role in limiting and guiding the movement of the first fitting part 110. Further, in some embodiments, the guide column 113 is connected to an elastic member (the elastic member can be a spring and is sleeved on the guide column 113), and the elastic member is configured to generate an elastic force driving the guide column 113 to move close to the second fitting part 120 along the first direction X. In order to make the cooperation of the guide column 113 and the second through hole 1214 more effective, the guide column 113, the second through hole 1214 and the elastic member can jointly form a guide group, and the magnetic connection device 100 can be provided with a plurality of guide groups distributed along the circumferential direction.
[0058] Similarly, in other embodiments, the second through hole 1214 can be arranged on the housing assembly 121, and one end of the guide column 113 is fixedly connected to a side of the second fitting part 120 close to the first fitting part 110 along the first direction X, and the other end of the guide column 113 is arranged through the second through hole 1214 and can abut against the housing assembly 121.
[0059] For the specific structure of the first fitting structure 111 and the second fitting structure 123, see Figures 5-6In some embodiments, along the first direction X, one side of the first engaging structure 111 has a first tooth shape 1111, and one side of the second engaging structure 123 has a second tooth shape 1231, the first tooth shape 1111 and the second tooth shape 1231 are engaged to enable the relative movement of the first engaging structure 111 and / or the second engaging structure 123 after being driven. It can be understood that when the user needs to magnetically fix the magnetically attractable device, the first tooth shape 1111 and the second tooth shape 1231 are engaged (which can be complete engagement or partial engagement), and when the first engaging structure 111 and / or the second engaging structure 123 are driven, the part of the first tooth shape 1111 and the second tooth shape 1231 that was originally engaged is no longer engaged. The above design of setting the part of the first engaging structure 111 and the second engaging structure 123 that engages each other as a tooth shape structure, on the one hand, can increase the structural stability of the first engaging structure 111 and the second engaging structure 123 engaging each other when magnetically fixing the magnetically attractable device, and it is more convenient to set the relative position of the two at the position of engaging each other; on the other hand, the tooth surface (the inclined tooth surface located on both sides of the tooth top) of the tooth shape structure can enable the first tooth shape 1111 and the second tooth shape 1231 to slide along the tooth surface of any one of them, and at the same time, the extension direction of the tooth surface has a component along the first direction X, so that the relative movement of the first tooth shape 1111 and the second tooth shape 1231 can enable the first engaging part 110 to move away from or close to the second engaging part 120 along the first direction X.
[0060] For more specific settings of the first tooth shape 1111 and the second tooth shape 1231, see Figures 1-6 In some embodiments, the first tooth shape 1111 has a first projection in the projection plane perpendicular to the first direction X, and the second tooth shape 1231 has a second projection in the projection plane, and the first projection and the second projection both extend along the circumferential direction around the first direction X. In other words, the above definition makes the first tooth shape 1111 and the second tooth shape 1231 both extend around the circumferential direction along the first direction X, so that the first tooth shape 1111 and the second tooth shape 1231 both form a closed ring-shaped tooth structure, which can be any shape of ring, such as a circular ring, a rectangular ring, etc. Through the above settings, on the one hand, the first tooth shape 1111 and the second tooth shape 1231 can form more stable support force and transmission force, and it is more convenient to install and position the first tooth shape 1111 and the second tooth shape 1231. In other embodiments, the first tooth shape 1111 and / or the second tooth shape 1231 can not form a closed ring structure, for example, the first tooth shape 1111 and the second tooth shape 1231 can both form a half-circle arc-shaped structure, or form a plurality of ring-shaped structures spaced along the circumferential direction.
[0061] In addition, in order to ensure that the relative movement of the first cooperating structure 111 and the second cooperating structure 123 can effectively make the separation action of the magnetically attractable device from the magnetic attraction surface 112 more labor-saving, and the first cooperating structure 111 and the second cooperating structure 123 do not occupy too much space, the parameters of the tooth profile structure can be limited. Specifically, see Figures 5-6 In some embodiments, the tooth height of the first tooth profile 1111 and the tooth height of the second tooth profile 1231 are both h, and the following is satisfied: 1mm≤h≤3mm. For example, h can be one of 1mm, 1.5mm, 2mm, 2.5mm, and 3mm. In some embodiments, when h=2mm, the magnetic attraction force between the magnetic attraction surface 112 and the mobile phone can be reduced from 25N to 5N after the first tooth profile 1111 and the second tooth profile 1231 move to the limit position away from each other.
[0062] Corresponding to different distance adjustment requirements or adjustment feeling requirements, in some embodiments, along the first direction X, one side of the first cooperating 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 0.6mm (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), so that the tooth height (or other parameters) between the first tooth profile 1111 and the third tooth profile 1112 can be specifically set according to different adjustment distances or different adjustment feelings. Similarly, the third tooth profile 1112 can also be arranged on the second cooperating structure 123, that is, along the first direction X, one side of the second cooperating structure 123 also has a fourth tooth profile 1232, and the difference between the tooth height of the second tooth profile 1231 and the tooth height of the fourth tooth profile 1232 is greater than or equal to 0.6mm. The fourth tooth profile 1232 arranged on the second cooperating structure 123 can be similarly referred to the third tooth profile 1112 arranged on the first cooperating structure 111 as described in the above embodiments, 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 at intervals, so that the user can engage the second tooth profile 1231 with the first tooth profile 1111 or the third tooth profile 1112 according to the requirements. Similarly, the second tooth profile 1231 and the fourth tooth profile 1232 can be arranged at intervals, so that the user can engage the first tooth profile 1111 with the second tooth profile 1231 or the fourth tooth profile 1232 according to the requirements. See Figures 9-10In some embodiments, the third tooth profile 1112 can be connected to the first tooth profile 1111 at the end thereof away from the magnetically attractable device along the first direction X, such that the tooth height of the third tooth profile 1112 is greater than the tooth height of the first tooth profile 1111, and during the relative circumferential movement, the second tooth profile 1231 can sequentially mesh with the first tooth profile 1111 and the third tooth profile 1112, and the fourth tooth profile 1232 can be connected to the second tooth profile 1231 at the end thereof close to the magnetically attractable device along the first direction X.
[0063] In some embodiments, the first mating structure 111 and the second mating structure 123 are relatively rotated along the circumferential direction based on the above description, and the second mating structure 123 is slidably connected to the housing assembly 121. In order to make the relative movement of the first mating structure 111 and the second mating structure 123 more smooth, for the first mating structure 111, referring to 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 123 can slide on the first inclined surface 1113 after being driven. It can be understood that by providing the first inclined surface 1113 and enabling the second mating structure 123 to slide on the first inclined surface 1113, the first mating portion 110 can be moved away from or close to the second mating portion 120 along the first direction X during the sliding process, and the distance adjustment between the first mating portion 110 and the second mating portion 120 is more convenient and smooth, and stepless adjustment can also be achieved. In order to achieve better adjustment effect, in some embodiments, the smallest angle between the first inclined surface 1113 and the magnetic attraction surface 112 is φ1, and satisfies: 30°≤φ1≤45°. Exemplarily, φ1 can take one of 30°, 35°, 40°, and 45°. Similarly, for the second mating structure 123, referring to Figures 5-6 In some embodiments, along the first direction X, one side of the second mating structure 123 has a second inclined surface 1233, and the first mating structure 111 can slide on the second inclined surface 1233 after being driven, and the smallest angle between the second inclined surface 1233 and the magnetic attraction surface 112 is φ2, and satisfies: 30°≤φ2≤45°. Exemplarily, φ2 can take one of 30°, 35°, 40°, and 45°. For the related settings and effects of the second inclined surface 1233, reference can be made to the above description of the first inclined surface 1113, which will not be repeated here. In addition, in some embodiments, the first mating structure 111 or the second mating structure 123 can have a third inclined surface, and the above description of the difference between the tooth heights being greater than or equal to 0.6 mm can be applied to the height difference between the third inclined surface and the first inclined surface 1113 or the second inclined surface 1233, and also has the effect of adapting to different distance adjustment requirements or adjustment feeling. Referring to Figures 5-6In combination with the foregoing embodiments for the first tooth profile 1111 and the second tooth profile 1231, the first inclined surface 1113 described above can correspond to the tooth surface (inclined tooth surface located on both sides of the tooth top) of the first tooth profile 1111, and the second inclined surface 1233 can correspond to the tooth surface (inclined tooth surface located on both sides of the tooth top) of the second tooth profile 1231.
