Description

A magnetic gravity bracket Technical Field

[0001] The utility model relates to the technical field of mobile phone brackets, and more specifically, to a magnetic gravity bracket. Background Art

[0002] With the development of mobile phone intelligent learning and entertainment technologies, people can complete a variety of operations such as online learning, watching videos and entertainment through their mobile phones. In order to free people's hands and improve the convenience of using mobile phones, mobile phone gravity holders have been widely used. Due to the popularity of mobile phones with magnetic suction functions, setting a magnetic suction component on the mobile phone holder has also become a commonly used structure in the existing technology. However, although the existing magnetic suction gravity holder has added a magnetic suction component, the use of the magnetic suction function is often easy to conflict with the use of the gravity support function. This is mainly because the existing two side clamping arms and bottom support arm structures for realizing gravity support are inconvenient to fold up. Due to the limitations of the two side clamping arms and bottom support arm structures, the clamping space is relatively fixed. The magnetic suction function is often used as an additional function to cooperate with the gravity support function, which is not convenient for the magnetic suction function to be used alone, and the user experience is not good.

[0094] As shown in FIG1 and FIG2 , an embodiment of the present invention is a magnetic gravity bracket, comprising a shell 10, a magnetic component 20 mounted on one side of the shell 10 and rotatable relative to the shell 10, and a clamping component 30 mounted on the shell 10 for clamping a mobile phone.

[0095] Housing 10

[0096] Referring to FIG. 2 , the housing 10 includes a first housing 11 and a second housing 12 engaged with the first housing 11 .

[0097] The first housing 11 of the housing 10

[0098] Please refer to Figure 3. The first shell 11 has a first base 110 and a first retaining wall 111. The first base 110 has three straight sides and one arc side. The first retaining wall 111 extends vertically from the edge of the first base 110. A first notch 1111 is formed between the first retaining wall 111 on the arc side and the first retaining wall 111 on the two adjacent straight sides. A recess 112 is provided at the central position of the first base 110 on the side facing away from the second shell 12 to accommodate the magnetic attraction component 20.

The recess 112 is further provided with a through hole 114, which is connected to the through hole 113 and is in the shape of an elongated strip. The through hole 114 is arranged above the through hole 113 along the vertical direction of the recess 112.

[0099] Referring to Figure 4 , a first receiving groove 115 is provided at the center of the other side of the first base 110, corresponding to and communicating with the through-hole 113. The diameter of the first receiving groove 115 is larger than that of the through-hole 113. On the first base 110, first sliding grooves 116 are provided horizontally on either side of the first receiving groove 115, respectively communicating with the two first notches 1111. A sliding space is provided vertically below the first receiving groove 115 on the first base 110. Within this sliding space, a second receiving groove 117 is provided below the first receiving groove 115. A baffle 118 is also provided below the second receiving groove 117 within this sliding space, perpendicular to the first base 110. A third receiving groove 119 is provided on the other side of the first base 110 near its bottom. A first side opening 1112 and a first bottom opening 1113 are correspondingly provided on the straight edges of one side and the bottom of the first base 110, communicating with the third receiving groove 119. The first base 110 is also provided with four first mounting holes 1114 for fastening and mounting with the second base 120. The four first mounting holes 1114 are arranged in pairs.

[0100] The second housing 12 of the housing 10

[0101] Referring to Figures 3 and 4 , the second housing 12 has the same appearance as the first housing 11, comprising a second base 120 and a second retaining wall 121. The second base 120 also has three straight sides and one curved side. The second retaining wall 121 extends perpendicularly from the edge of the second base 120. A second notch 1211 is formed between the second retaining wall 121 on the curved side and the second retaining wall 121 on two adjacent straight sides. A second chute 122 is provided on one side of the second base 120, communicating with both second notches 1211. Three first mounting posts 1220, a second mounting post 1222, and a third mounting post 1224 are arranged in an inclined manner from top to bottom in the center of the chute wall within the second chute 122. A first guide post 1226 is provided on the chute wall within the second chute 122, located above the first mounting post 1220, and a second guide post 1228 is provided below the third mounting post 1224. A fourth receiving groove 123 is provided near the bottom of the second base 120, corresponding to the third receiving groove 119. A second side opening 1212 is provided on a straight edge of one side of the second base 120, communicating with the fourth receiving groove 123. Upper and lower stoppers 124 are provided on the wall of the second slide groove 122, near the two second notches 1211. The second base 120 is also provided with four second mounting holes 1214, corresponding to each other, for securely mounting the second base 110. The four second mounting holes 1214 are arranged in pairs.

[0102] In this embodiment, the first housing 11 and the second housing 12 are connected by fasteners. During installation, the fasteners are passed through the second mounting holes 1214 and then inserted into the first mounting holes 1114 and tightened or screwed. Fasteners include but are not limited to screws, bolts, rivets, and other fastening components.

[0103] Magnetic component 20

[0104] Please refer to Figures 5 and 6. The magnetic assembly 20 includes a chassis 21 and a magnetic ring 22 arranged in the chassis 21. A mounting hole 210 for the fastener to pass through is provided at the central position of the chassis 21. A mounting groove 211 for mounting the magnetic ring 22 is provided on the chassis 21 at a position located on the periphery of the mounting hole 210. The size of the mounting groove 211 is adapted to the size of the magnetic ring 22. The size of the chassis 21 is adapted to the size of the recess 112. The shape of the recess 112 is annular, and correspondingly, the shape of the chassis 21 is also annular. The mounting hole 210 corresponds to the through hole 113 on the first shell 11. During installation, the chassis 21 is placed in the recess 112, and the fastener passes through the mounting hole 210 and is connected to a rotating assembly 60 located in the through hole 113. Among them, the fasteners include but are not limited to screws, rivets and other fastening parts; it can be understood that the installation method of installing the magnetic ring 22 on the chassis 21 is relatively existing, and an existing appropriate installation method can be used, which will not be repeated here.

[0105] Rotating assembly 60

[0106] Please refer to Figures 6 and 7. The rotating assembly 60 includes a gear 61 movably set in the through hole 113 and the first receiving groove 115, and a positioning bead 62 movably set in the through hole 114. The positioning bead 62 rotates with the teeth of the gear 61, and the positioning bead 62 moves up and down as the teeth of the gear 61 rotate.

[0107] Gear 61 includes a connecting portion and a gear portion integrally formed with the connecting portion. During installation, the connecting portion is securely connected to the chassis 21 through a through hole 113, while the gear portion is located in a first receiving slot 115. The dimensions of first receiving slot 115 should be compatible with the gear portion, and the dimensions of through hole 114 should be compatible with the connecting portion to allow for the rotation of gear 61. When the user uses the magnetic function alone, the rotating magnetic assembly 20 allows the user to adjust the phone's display orientation by rotating the magnetic assembly 20 without having to remove the phone and reposition it.

[0108] It should be noted that the structure of the positioning bead 62 used in this embodiment is relatively existing, and reference may be made to the existing positioning bead structure including a positioning bead body and a spring.

[0109] During installation, the spring is set in the through hole 114, so that one end of the spring is connected to the positioning bead body, and the other end is connected to the inner top wall of the through hole 114 to form an elastic reset structure, and then the positioning bead body is partially placed between the two adjacent teeth of the gear part, and the positioning bead body moves up and down with the rotation of the gear. For example, when the positioning bead body is lifted by the top of the gear tooth, it moves upward back into the through hole 114. When the positioning bead body moves downward, it is placed in the recess formed by the two adjacent teeth, so that the magnetic attraction component 20 produces a "clicking" sound when it rotates relative to the shell 10.

[0110] Clamping assembly 30

[0111] 8 , the clamping assembly 30 includes a gravity support base 31 movably connected to the housing 10 and a first clamping arm 32 and a second clamping arm 33 connected to the gravity support base 31. The gravity support base 31, the first clamping arm 32 and the second clamping arm 33 are linked by a linkage assembly 40.

[0112] Please refer to FIG. 9 . The gravity support base 31 includes a vertically disposed support arm 310 and a supporting portion 311 rotatably connected to the end of the support arm 310 .

[0113] The support arm 310 is provided with a first hollow groove 301 and a second hollow groove 302 corresponding to each other in the upper and lower parts. A vertical rack portion 312 is provided on the inner side wall of the first hollow groove 301 .

[0114] A fixing post 3021 is provided on the inner top wall of the second hollowed-out slot 302. A first elastic return member (not shown in the drawings) is sleeved on the fixing post 3021. The end of the first elastic return member, distal from the fixing post 3021, abuts against the baffle 118. The second hollowed-out slot 302 corresponds to the second receiving slot 117. When fully installed, the first elastic return member is partially located within the second receiving slot 117.

[0115] The support portion 311 is rotatably connected to the end of the support arm 310 via a rotating shaft. A torsion spring (not shown in the drawings) is provided on the rotating shaft. The torsion spring has two torsion bars, one of which abuts against the support portion 311, while the other abuts against the support arm 31. This acts as an elastic reset force on the support portion 311, allowing the support portion 311 to rotate and open relative to the support arm 31. The support portion 311 has a 90° folding angle. When the support portion 311 is folded open by the elastic force of the torsion spring, the support portion 311 is perpendicular to the support arm 310. The raised portion connected to the rotating shaft at the end of the support arm 31 is configured in a teardrop shape that is wide at the top and narrow at the bottom. This ensures that when the support portion 311 is folded to a position perpendicular to the support arm 310, it is blocked and cannot move. A slot 3011 is provided at the bottom of the support portion 311.

[0116] It should be noted that the torsion spring structure with two torsion bars is relatively existing, and the existing torsion spring structure can be used to achieve the elastic reset function, which will not be described in detail here.

[0117] Please refer to FIG. 10 , the first clamping arm 32 includes a first supporting portion 320 and a first clamping portion 321 rotatably connected to the first supporting portion 320 .

[0118] A first transverse rack portion 322 is provided on the first bearing portion 320. A first transverse positioning bar 323 is provided on the first bearing portion 320 below the first transverse rack portion 322, with a movable space formed between the first transverse rack portion 322 and the first transverse positioning bar 323. The first transverse rack portion 322 is provided with a plurality of gear teeth arranged in a horizontal parallel pattern on the end facing the first transverse positioning bar 323. A first guide bar 324 is provided on the end of the first transverse rack portion 322 facing away from the gear teeth, with a first guide groove 325 formed between the first transverse rack portion 322 and the first guide bar 324. Both the first guide bar 324 and the first transverse positioning bar 323 are provided with a first stopper 326 on the end facing away from the first clamping portion 321, which engages with the limit block 124.

[0119] Referring to Figure 11 , the first support member 320 slides within the second guide slot 122 and one of the first guide slots 116. The second guide slot 122 and one of the first guide slots 116 are shown in Figures 3 and 4 . When the first support member 320 moves leftward to a designated position, the first guide post 1226 engages the first guide slot 325. When the first support member 320 moves rightward to a designated position, the first stopper 326 abuts against the stopper 124.

[0120] The first clamping portion 321 is rotatably connected to the end of the first bearing portion 320 via a rotating shaft. A torsion spring (not shown in the drawings) is also provided on the rotating shaft. The structure of the torsion spring is consistent with the above description. One end of the torsion spring is pressed against the first clamping portion 321, and the other end of the torsion spring is pressed against the first bearing portion 320, thereby exerting an elastic reset effect on the first clamping portion 321.

[0121] Referring to Figures 11 and 12 , the first clamping portion 321 folds open at a 90° angle. When the first clamping portion 321 is folded open by the torsion spring, the first clamping portion 321 is perpendicular to the support arm 310. The protrusion on the first support portion 320 for mounting the rotating shaft is designed in a teardrop shape that is wide inside and narrow outside. This ensures that when the first clamping portion 321 folds to a position perpendicular to the first clamping portion 321, it is stopped and cannot move.

[0122] Please refer to FIG. 10 , the second clamping arm 33 includes a second supporting portion 330 and a second clamping portion 331 rotatably connected to the second supporting portion 330 .

[0123] The second support portion 330 is provided with a second transverse rack portion 332. A second transverse positioning bar 333 is provided on the second support portion 330 above the second transverse rack portion 332. A movable space is also formed between the second transverse rack portion 332 and the second transverse positioning bar 333. The second transverse rack portion 332 is also provided with a plurality of gear teeth arranged in a horizontal parallel pattern on the end facing the second transverse positioning bar 333. A second guide bar 334 is provided on the end of the second transverse rack portion 332 facing away from the gear teeth. A second guide groove 335 is formed between the second transverse rack portion 332 and the second transverse positioning bar 333. Both the second guide bar 334 and the second transverse positioning bar 333 are provided with a second stopper 336 on the end facing away from the second clamping portion 331, which engages with the limit block 124.

[0124] Referring to Figure 11 , the second support member 330 slides within the second guide slot 122 and the other of the first guide slots 116. The second guide slot 122 and the other of the first guide slots 116 are shown in Figures 3 and 4 . When the second support member 330 moves rightward to a designated position, the second guide post 1228 engages the second guide slot 335. When the second support member 330 moves leftward to a designated position, the second stopper 336 abuts against the stopper 124.

[0125] The second clamping portion 331 is also rotatably connected to the end of the second bearing portion 330 via a rotating shaft. A torsion spring (not shown in the drawings) is also provided on the rotating shaft. The structure of the torsion spring is consistent with the previous description. One end of the torsion spring is pressed against the second clamping portion 331, and the other end of the torsion spring is pressed against the second bearing portion 330, thereby exerting an elastic reset effect on the second clamping portion 331.

[0126] The second clamping portion 331 also folds open at a 90° angle. When the second clamping portion 331 is folded open by the torsion spring, it becomes perpendicular to the support arm 310. The protrusion on the second support portion 330 for mounting the rotating shaft is also designed in a teardrop shape, wide inside and narrow outside. This ensures that when the second clamping portion 331 is folded to a perpendicular position, it is prevented from moving.

[0127] In this embodiment, the support arm 310 is arranged vertically, while the first support portion 320 and the second support portion 330 are arranged horizontally relative to each other. When the support portion 311, the first clamping portion 321, and the second clamping portion 331 are folded and unfolded, a clamping space is formed between the support portion 311 and the housing 10. When a mobile phone is placed on the support portion 311, the support arm 310 moves downward due to gravity. Simultaneously, the first support portion 320 and the second support portion 330 move left and right relative to each other, clamping the mobile phone through the first clamping portion 321 and the second clamping portion 331.

[0128] Linkage component 40

[0129] 13 and 14 , the linkage assembly 40 includes a main gear 41, a first sub-gear 42, and a second sub-gear 43 that mesh with each other. The main gear 41 is movably mounted on the second mounting post 1222, while the first sub-gear 42 and the second sub-gear 43 are movably mounted on the first mounting post 1220 and the third mounting post 1224, respectively.

[0130] Referring to Figures 11 and 15 , the main gear 51 meshes with the vertical rack portion 312, the first sub-gear 52 meshes with the first transverse rack portion 322, and the second sub-gear 53 meshes with the second transverse rack portion 332. The first transverse rack portion 322 is positioned between the first sub-gear 52 and the first guide post 1226; the top of the first transverse rack portion 322 is restrained by the first guide post 1226. The second transverse rack portion 332 is positioned between the second sub-gear 52 and the second guide post 1228; the bottom of the second transverse rack portion 332 is restrained by the second guide post 1228.

[0131] To retract, the first clamping portion 321 and the second clamping portion 331 are manually folded and pressed, and then the first supporting portion 320 and the second supporting portion 330 are simultaneously pushed toward the interior of the housing. While pushing, the first clamping portion 321 and the second clamping portion 331 are kept in the pressed and folded state until the first clamping portion 321 and the second clamping portion 331 are pushed back into the interior of the housing 10 together with the first supporting portion 320 and the second supporting portion 330. As the first supporting portion 320 and the second supporting portion 330 are pushed into the interior of the housing 10, the support arm 310 moves downward to a suitable position. At this time, the supporting portion 311 is manually folded and pressed, and the pressed state is maintained so that the slot 3011 on the supporting portion 311 is snap-fastened to the housing 10 by a control assembly 50, thereby fixing the supporting portion 311 relative to the housing 10, and the gravity clamping portion of the magnetic gravity bracket is completely retracted. For a detailed retracted state, please refer to FIG. 17 .

[0132] When unfolding, the supporting part 311 is opened by a control component 50 that fixes the supporting part 311 on the shell 10. The supporting part 311 is automatically folded and popped outward under the force, and the support arm 310 is automatically moved upward a certain distance under the elastic force of the first elastic return member, so that the first bearing part 320 and the second bearing part 330 are driven by the linkage component 40 to extend from the inside of the shell 10 and move to the left and right sides of the shell 10. After the first bearing part 320 and the second bearing part 330 move a certain distance, the first clamping part 321 and the second clamping part 331 are automatically folded and popped outward under the elastic force. Please refer to Figure 1 for the unfolded state.

[0133] It should be noted that the certain distance that the support arm 310 moves refers to the distance that can drive the first bearing part 320 and the second bearing part 330 to move outward to a suitable position, and the certain distance that the first bearing part 320 and the second bearing part 330 move refers to the distance that can enable the first clamping part 321 and the second clamping part 331 to automatically pop open when the first clamping arm 32 and the second clamping arm 33 move outward to a suitable position. The moving distance shown in the drawings is only an example and does not constitute a specific limitation.

[0134] Control component 50

[0135] Referring to Figure 16 , the control assembly 50 includes a clamping block 51, a second elastic return member (not shown), and a protrusion 52. The top of the clamping block 51 is provided with a socket 510 for inserting the second elastic return member. The side walls of the clamping block 51 are provided with recesses 511 that form a press-fit with the protrusion 52. The protrusion 52 also has corresponding protrusions 521 on its two opposing side walls.

[0136] Referring to Figures 3 and 4 , after the first and second housings 11 and 12 are fastened together, the third receiving groove 119 and the fourth receiving groove 123 correspondingly engage to form a mounting groove. The first side opening 1112 and the second side opening 1212 correspondingly engage to form a side opening communicating with the mounting groove. The first bottom opening 1113 communicates with the mounting groove to form a bottom opening. The groove walls of the third and fourth receiving grooves 119 and 123, respectively, that contact the protrusion 52, are also provided with first and second limiting grooves 1190 and 1230 that engage with the protrusion 521. The two opposing side walls of the protrusion 521 are correspondingly engaged with the first and second limiting grooves 1190 and 1230.

[0137] Referring to Figure 17 , a protrusion 52 is positioned within the mounting slot and partially protrudes from the side opening to the exterior of the housing 10. In this embodiment, a retaining block 51 is positioned within the mounting slot. The end of a second elastic return member, distal from the retaining block 51, abuts against the inner top wall of the mounting slot (not shown in the accompanying drawings). The retaining block 51 extends in and out of the bottom opening under the action of the protrusion 52 and the second elastic return member. Pressing the protrusion 52 causes the retaining block 51 to move upward, and the supporting portion 311, unrestricted, automatically springs open, disengaging from the housing 10.

[0138] In this embodiment, both the first elastic return member and the second elastic return member are springs. To enhance protection for the mobile phone and prevent it from wear and tear, gaskets (not shown in the drawings) are provided on the surfaces of the supporting portion 311, the first clamping portion 321, and the second clamping portion 331 that contact the mobile phone.

[0139] It should be understood that ordinary technical workers in this field can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this utility model.
