Description

Technical Field

[0001] The present invention relates to products for data / electrical energy connection, and in particular to a modular magnetic connection unit, a storage rack and a charging device. Background Art

[0002] Smart terminals, such as smartphones and tablets, usually use data cables / power cables to transmit data and power. In order to reduce the plugging action, magnetic cables have appeared on the market. That is, when the plug is inserted into the smart terminal, the end of the magnetic cable and the plug can be attracted to each other by magnetic attraction. When no wiring is needed, the end and the plug can be directly unplugged, which greatly improves the convenience of use. Users generally need to purchase specific magnetic data cables to apply this magnetic connection structure. Magnetic plugs are generally always plugged into smart terminals and are rarely removed. Ordinary data cables do not have a magnetic connection structure, so users' existing ordinary data cables are rarely used. The market also lacks a small modular product that allows ordinary data cables to also apply a magnetic connection structure. Summary of the Invention

[0045] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below.

[0046] First embodiment

[0047] The first embodiment is a magnetic connection unit 213. Figure 1-1 、 1-2 As shown, the magnetic connection unit 213 includes a housing 2130, a magnetic terminal 214, and external components. The housing 2130 is a cube and includes an upper cover 2131 and a lower cover 2132. The top plate 2133 is located on the upper cover 2131, and the bottom plate 2134 is located on the lower cover 2132. Two opposing slides 2135 are provided on the outer wall of the housing 2130, and the slides 2135 are located between the upper cover 2131 and the lower cover 2132. The insertion port of the slide 2135 is located at the insertion end of the magnetic connection unit 213, facilitating the magnetic connection unit 213 to be plugged into a storage rack or charging device for use. When the magnetic connection unit 213 is plugged into a storage rack or charging device for use, the magnetic connection unit 213 is placed in the corresponding position of the smart terminal where the magnetic plug is plugged in. The magnetic terminal 214 magnetically connects to the magnetic plug of the smart terminal and simultaneously achieves an electrical connection.

[0048] like Figure 1-1 As shown, the magnetic terminal 214 can pass through the top plate 2133 of the housing 2130, and the external component is the socket 223, and the socket 223 is exposed from the front end of the magnetic connection unit 213. Figure 1-2 As shown, the four metal tabs 2136 embedded and fixed in the bottom plate 2134 of the lower cover 2132 are external components for receiving external power or power and data. Figure 1-2 As shown, a through-hole 2137 for mounting a vacuum suction cup head is provided in the middle of the bottom plate 2134 of the lower cover 2132. This is used to insert and install the vacuum suction cup when the magnetic connection unit 213 is used alone to better secure the magnetic connection unit 213. Four positioning bumps 2138 are provided on the other side of the magnetic connection unit 213, which are mainly used to position the magnetic connection unit 213 when it is plugged into an external device.

[0049] Combine Figure 2 、 3As shown, upper and lower buffer pads 99, buffer pads 96, compression springs 98, circuit boards 97 and metal sheets 95 are provided between the upper cover 2131 and the lower cover 2132 of the housing 2130. The external components are used to connect electrical energy or electrical energy and data to the circuit board 97 and the magnetic terminal 214. The external components are the socket 223 and the metal contact 2136. The magnetic terminal 214, the socket 223 and the metal contact 2136 are all electrically connected to the circuit board 97. The magnetic terminal 214 is movable in the housing 2130, and the magnetic terminal 214 can pass through the top plate 2133 of the housing 2130. The magnetic terminal 214 is used to be magnetically fixed to the magnetic plug plugged into the smart terminal and to form an electrical connection. Among them, the socket 223 is used to plug in the external wiring harness (data cable) and establish an electrical connection. The socket 223 and magnetic terminal 214 are both fixed to the circuit board 97. The circuit board 97, magnetic terminal 214, and socket 223 can move synchronously back and forth in a linear direction perpendicular to the circuit board 97. Socket 223 is a USB-A, Type-C, Micro-USB, Mini-USB, or Lightning interface. Four light beads 94 are evenly distributed around the magnetic terminal 214 on the circuit board 97. These light beads 94 are electrically connected to the circuit board 97 and are used to indicate the operating status. A compression spring 98 is mounted on the outside of the magnetic terminal 214. One end of the compression spring 98 abuts against the circuit board 97, and the other end abuts against the inner wall of the top plate 2133 of the housing 2130. The compression spring 98 is primarily used to push the circuit board 97 back to its original position when the magnetic terminal 214 is not connected to the magnetic plug. Cushion pads 96 and 99 are located on either side of the circuit board 97, respectively, away from the magnetic terminal 214 and socket 223. The primary function of cushions 96 and 99 is to reduce noise and protect electronic components. Since circuit board 97 is removable, metal tab 2136 is embedded and fixed within bottom plate 2134 of lower cover 2132 and exposed outside of bottom plate 2134. Therefore, metal tab 2136 can be electrically connected to circuit board 97 via a flexible wiring harness (not shown) or FPC (not shown). Furthermore, metal tab 95 secured within magnetic connection unit 213 is ferromagnetic and is used to secure magnetic connection unit 213 to an external magnet.

[0050] like Figure 4 The figure shows a working state of the magnetic connection unit 213. Figure 4 The magnetic connection unit 213 is used alone, and the magnetic connection unit 213 is placed on a plane (a vacuum suction cup can also be installed on the bottom plate to be more firmly fixed on the plane through the vacuum suction cup). Figure 4The mobile phone in the middle is placed directly on the magnetic connection unit 213, the top plate 2133 of the shell 2130 independently supports the smart terminal 999, and the magnetic end is electrically connected to the magnetic plug inserted in the smart terminal 999. The back of the smart terminal 999 is also placed on an external vertical surface or a fixed object, and an ordinary data cable is inserted into the socket 223 of the magnetic connection unit 213. The ordinary data cable can be electrically connected to the smart terminal 999 through the magnetic connection structure, and the smart terminal 999 can also be stably stood up for viewing and operation.

[0051] Second embodiment

[0052] The second embodiment is a storage rack, which is mainly used to place smart terminals, such as smart phones, tablet computers, etc., and a magnetic plug is inserted into the data / power socket of the smart terminal. Figure 5 、 6 As shown, the storage rack includes a base structure 202 and a back plate structure 201. The back plate structure 201 can be pulled out upward from the base structure 202. When in use, the back plate structure 201 must first be plugged downward onto the base structure 202.

[0053] like Figure 7 、 8 As shown, the base structure 202 includes a bottom plate 217 and a strip plate 216. The bottom plate 217 itself is a plane, and an edge of the bottom plate 217 is provided with an upwardly curved oblique insert plate 221. The strip plate 216 is a long strip, and a strip groove 218 is provided on one side of the long side of the strip plate 216. A lower groove 219 is provided on the other side of the long side of the strip plate 216, and the lower groove 219 is arranged opposite the strip groove 218. The lower groove 219 of the strip plate 216 is used to plug into the oblique insert plate 221 and is fixed to each other via three short nails 225. A first support plate 220 is also provided on one side of the strip plate 216 where the strip groove 218 is provided. The first support plate 220 is long and parallel to the length of the strip groove 218.

[0054] like Figure 7 、 8 As shown, the backplane structure 201 includes a front cover 203 and a back cover 204 that are fixedly connected to each other. The front cover 203 includes a support surface 208 and a connecting seat 209. The long sides of the rectangular support surface 208 are long inserts 2081, and the short sides of the support surface 208 are fixedly connected to the connecting seat 209. A short insert 212 is also provided on the outside of the connecting seat 209. The side wall of the connecting seat 209 connected to the front cover 203 and perpendicular to the support surface 208 is a second support plate 210. The short insert 212 and the long insert 2081 are perpendicular to each other, with the short insert 212 parallel to the short side of the support surface 208 and the long insert 2081 parallel to the long side of the support surface 208. The relative positions of the support surface 208, the short insert 212, and the long insert 2081 are fixed.

[0055] like Figure 7 、 8 As shown, four cylinders 206 are used to fix four magnets 222 on the back cover 204. The magnets 222 are used to magnetically fix ferromagnetic smart terminals. For example, when an iron sheet is attached to the back of a smart phone, it can be attracted and fixed by the magnets 222.

[0056] like Figure 7 、 8 As shown, the rearward-facing inner cavity 224 of the connection base 209 is plugged with a magnetic connection unit 213 of the first embodiment. In practice, if the magnetic connection unit 213 is only used on the storage rack, the metal tab can be omitted from the external connection component, and only the socket 223 can be retained as the external connection component.

[0057] The second support plate 210 is provided with a through hole 211 for the magnetic end 214 to pass through, and the through hole 211 is connected to the inner cavity 224 of the connection base 209. A spring 215 is also inserted into the connection base 209. The restoring force of the spring 215 is used to keep the magnetic connection unit 213 close to the inner wall of the inner cavity 224 where the through hole 211 is located, so as to prevent the magnetic connection unit 213 from being separated from the inner cavity 224. Figure 7 、 8 As shown, the spring piece 215 is an elastic metal sheet bent into a V-shape, and the material can be spring steel.

[0058] like Figure 8 As shown, the length direction of the inner cavity 224 is direction A (bidirectional), and the depth direction is direction B (bidirectional). Direction A and direction B are perpendicular to each other and form a first plane with direction A and direction B passing through the center of the inner cavity 224. The length of the inner cavity 224 is greater than the length of the magnetic connection unit 213 in direction A. Therefore, the position of the magnetic connection unit 213 in direction A and direction B of the inner cavity 224 is adjustable, which can meet the needs of smart terminals of different types and sizes (including length, width, and thickness) when placed horizontally or vertically for free adjustment. At the same time, the length of the perforation 211 is also made into a long strip, so that the magnetic terminal 214 can pass through when the magnetic connection unit 213 is in different positions. When in use, a smart terminal is placed on the shelf, and the inner cavity 224 corresponds to the data / power socket of the smart terminal (not shown). First, adjust the position of the magnetic connection unit 213 so that the magnetic end 214 is aligned with the magnetic plug, so that the magnetic end 214 and the magnetic plug are magnetically attracted and electrically connected, and the first plane of the inner cavity 224 (i.e., direction A, direction B) is perpendicular to the insertion direction of the magnetic plug.

[0059] Alternatively, in other embodiments, the spring may not be used, and a magnet may be provided at the bottom of the inner cavity of the connection base, and a ferromagnetic metal sheet may be fixed in the magnetic connection unit, and the magnetic connection unit may be fixed in the inner cavity by magnetic force.

[0060] In other embodiments, more than one connection base may be provided on the front cover, each connection base having an inner cavity and a magnetic connection unit. When the inner cavity is large enough, multiple magnetic connection units may be placed in one inner cavity.

[0061] like Figure 7 、 8 As shown, the gap between the front cover 203 and the back cover 204 can accommodate a decorative sheet 205, such as a printed photo or landscape painting. The back cover 204 is provided with two ribs 207, which support the decorative sheet 205 and prevent it from bending. The front cover 203 should be made transparent, such as from acrylic or transparent PVC, so that the pattern on the decorative sheet 205 can be seen through the front cover 203.

[0062] In other embodiments, the ribs may also be designed to be vertical to make it easier to insert the decorative sheet into place.

[0063] like Figure 6 As shown, when the backplane structure 201 is inserted into the strip-shaped slot 218 via the short insert plate 212, the support surface 208 and the second support plate 210 are used to support the vertically placed smart terminal. At this time, the second support plate 210 is parallel to the first support plate 220, the back of the smart terminal is closely attached to the support surface 208, and the bottom is closely attached to the second support plate 210. The magnetic end of the magnetic connection unit is magnetically fixed to the magnetic plug inserted at the bottom of the smart terminal, forming an electrical connection for charging.

[0064] like Figure 9 As shown, when the backplane structure 230 is inserted into the strip-shaped slot 232 via the long insert plate 231, the support surface 233 and the first support plate 234 are used to support the horizontally placed smart terminal. At this time, the first support plate 234 and the second support plate 235 are perpendicular, the back of the smart terminal is closely attached to the support surface 233, the side of the horizontally placed smart terminal is closely attached to the first support plate 234, and the bottom of the smart terminal is closely attached to the second support plate 235. The magnetic end 241 of the magnetic connection unit 240 is magnetically fixed to the magnetic plug inserted at the bottom of the smart terminal, forming an electrical connection for charging. Figure 9 and Figure 10 There are two different states. The difference is Figure 9 The connection seat 236 is on the left, Figure 10 The connecting seat 237 is on the right and the long insert plate 238 on the opposite side is inserted into the strip groove 239.

[0065] The bottom plate 217 is made of deformable plastic, that is, the bottom plate 217 is freely deformable. Figure 11As shown, the base plate 217 is embedded with a shaping piece 244 made of a metal material that is easy to plastically deform (such as stainless iron). The shaping piece 244 is used to allow the base plate 217 to maintain its deformed shape after bending and deformation. During implementation, the area enclosed by the outer edge of the shaping piece 244 should reach more than 90% of the area of the base plate 217 itself. The edge of the base plate 217 is warped upward to form an inclined insert plate 221, which is a part of the base plate 217. At the same time, the shaping piece 244 also extends into the inclined insert plate 221. The inclined insert plate 221 can be used to support the backplane structure 201. Because the base plate 217 itself is deformable, the warping angle of the inclined insert plate 221 can be adjusted and the height of the inclined insert plate 221 can be adjusted. In addition, due to the presence of the shaping piece 244, the inclined insert plate 221 can be directly fixed after adjustment. When the product leaves the factory, the bottom plate 217 is a flat surface with a bending line marked on it to remind the user to bend it according to the position to form the inclined insert plate 221. The user can also bend it away from the bending line and adjust the height angle of the inclined insert plate 221. In addition, in order to make it easier for the user to deform the bottom plate 217 and enhance the user experience, such as Figure 11 As shown, the shaping piece 244 can be hollowed out appropriately in the middle, but a certain rigidity and strength should be ensured.

[0066] Third embodiment

[0067] The third embodiment is a storage rack. The storage rack of the third embodiment is improved on the basis of the storage rack of the second embodiment. Therefore, only the improvements of the storage rack of the third embodiment are described below, and the same structural contents as the second embodiment are not repeated.

[0068] like Figure 12 As shown, the entire supporting surface of the first supporting plate 242 is further provided with anti-skid grooves 243 for enhancing friction and preventing the supported smart terminal from slipping.

[0069] like Figure 13 As shown, the base structure 202 also includes two support plates 245, one long and one short, and the bottom plate 217 is provided with two receiving slots 246 for accommodating and securing the two support plates 245. The support plates 245 are positioned within the acute angle formed by the oblique insert plate 221 and the bottom plate 217. The support plates 245 are used to strengthen the support of the strip plate 216, thereby preventing the possibility of a large and heavy smart terminal falling due to insufficient support.

[0070] like Figure 13 As shown, the bottom plate 217 is provided with seven first slots 247, and the strip plate 216 is provided with one second slot 248. In a specific implementation, the number of the first slots 247 and the second slots 248 can be adjusted. Figure 14 、 15As shown, when in use, one end of the support plate 245 is inserted into and abuts against the second slot 248 of the strip plate 216, and the other end is inserted into and abuts against one of the first slots 247 of the bottom plate 217, thereby forming a triangular structure, which can greatly improve the supporting force of the strip plate 216 and will not fall down when placing a larger and heavier smart terminal.

[0071] like Figure 14 、 15 As shown, each receiving slot 246 is provided with a positioning post 249, and a corresponding locking hole 250 is provided on the support plate 245. When the support plate 245 is placed and secured in the receiving slot 246, the positioning post 249 locks into the locking hole 250. Because the base plate 217 is made of deformable plastic, the positioning post 249 is an integral part of the base plate 217. The locking hole 250 and the positioning post 249 can be configured to fit tightly together, effectively securing the support plate 245 while also allowing for easy removal. In practice, the support plate 245 should be made of a hard material, such as hard plastic or steel.

[0072] Alternatively, in other embodiments, the second slot 248 in the third embodiment may not be used, such as Figure 16-1 、 16-2 As shown, the base plate 260 is provided with seven first slots 261, and the strip plate 262 is provided with two parallel lugs 263. One end of the support plate 264 is inserted into and abuts against the first slot 261 of the base plate 260, while the other end has a protruding point 265 (or a central axis with exposed ends inserted therein) that is inserted between the two lugs 263 to form a detachable hinged connection with the lugs 263.

[0073] In other embodiments, Figure 17 、 18 As shown, the backplane structure 201 is a flat plate, the surface of the flat plate is the support surface 208, and the short insert 2082 and the long insert 2081 are the outer edges of the flat plate. A magnetic connection unit 213 is plugged into the flat plate. The outer surface of the magnetic connection unit 213 for the magnetic end 214 to pass through is the second support plate 210. A T-shaped piece 2086 passes through the slender strip hole 2083 of the flat plate and is inserted and fixed to the magnetic connection unit 213, so that the magnetic connection unit 213 can be translated and adjusted in the length direction of the slender strip hole 2083 of the flat plate and the magnetic connection unit 213 can bear weight. A triangular wedge block 2087 is provided on the T-shaped piece 2086 for clamping with the magnetic connection unit 213, and the T-shaped piece 2086 is also provided with a threading hole 2084 for the external wiring harness to pass through. The back panel of the T-shaped piece 2086 is curved and, when the magnetic connection unit 213 is connected, it abuts against the back of the tablet, better securing the magnetic connection unit 213. Furthermore, a threading hole 2085 is provided above the elongated hole 2083 of the tablet for connecting an external wiring harness to the socket of the magnetic connection unit 213.

[0074] Fourth embodiment

[0075] The charging device of the fourth embodiment is a vehicle-mounted bracket. Figure 19 As shown, a accommodating cavity 102 is provided on the lower arm 101 of the vehicle bracket, and a modular magnetic connection unit 103 has been inserted into the accommodating cavity 102. A movable magnetic terminal 104 is provided in the magnetic connection unit 103. A magnetic terminal 104 and a magnetic plug (not shown) are a group. When in use, the magnetic plug is inserted into a smart terminal (such as a smart phone, tablet computer, etc.). Figure 20 、 21 This is an exploded view of the magnetic connection unit 103 being pulled out of the accommodating cavity 102. The structure of the magnetic connection unit 103 employed in the fourth embodiment differs from that of the first embodiment in that the socket and the through-hole for mounting the vacuum suction cup are omitted. Therefore, the metal tab 114 in the fourth embodiment serves as an external component of the magnetic connection unit 103.

[0076] like Figure 20 、 21 As shown, the accommodating chamber 102 is surrounded by a rear wall 106, a bottom plate 107, and two side walls 105. The accommodating chamber 102 is provided with a first opening 109 facing the front, through which the magnetic connection unit 103 can pass when inserted or removed. The accommodating chamber 102 is also provided with a second opening 108 facing upward, and the second opening 108 faces the smart terminal placed on the charging device. When the magnetic connection unit 103 is inserted into the accommodating chamber 102, the side where the magnetic terminal 104 is located is flush with the second opening 108. In other embodiments, the first opening of the accommodating chamber can also be opened on the side.

[0077] like Figure 20 、 21 As shown, the accommodating chamber 102 is provided with two slide rails 112, which are arranged parallel to each other and opposite each other. Two slide grooves 1035 on the outer wall of the housing of the magnetic connection unit 103 correspond to the slide rails 112. When the magnetic connection unit 103 is inserted into the accommodating chamber 102, the slide rails 112 are inserted into the slide grooves 1035, forming a sliding connection. The slide rails 112 and the slide grooves 1035 cooperate to limit and guide the sliding travel of the magnetic connection unit 103 within the accommodating chamber 102.

[0078] like Figure 20 、 21As shown, the accommodating cavity 102 is provided with four metal springs 110 with protrusions, and the magnetic connection unit 103 is provided with metal contacts 114 corresponding one to one with the metal springs 110. A main circuit board (not shown) is provided in the charging device, and the metal springs 110 are electrically connected to the main circuit board, and the main circuit board is powered by an external power supply or a built-in power supply. When the metal contacts 114 are in close contact with the metal springs 110, an electrical connection is formed. There are four metal springs 110, which can transmit electrical energy and data. In other embodiments, if only electrical energy needs to be transmitted, only two metal springs can be provided.

[0079] like Figure 20 、 21 As shown, the accommodating cavity 102 is provided with four positioning pits 111, and the outer wall of the magnetic connection unit 103 is provided with corresponding positioning bumps 113. When the magnetic connection unit 103 is inserted into the accommodating cavity 102 until the positioning bumps 113 are placed in the positioning pits 111, the metal contact 114 has contacted the metal spring 110 to achieve electrical connection, and the magnetic connection unit 103 is in the working position, at which point a smart terminal can be placed to charge.

[0080] In other embodiments, the accommodating cavity is provided with at least one positioning protrusion, and the outer wall of the magnetic connection unit is provided with a corresponding positioning pit. When the magnetic connection unit is inserted into the accommodating cavity and is in the working position, the positioning protrusion is placed in the positioning pit.

[0081] During use, first align and insert the magnetic connection unit 103 into the receiving cavity 102 until the positioning protrusion 113 is placed in the positioning pit 111. The metal contact 114 and the protrusion of the metal spring 110 are in close contact and electrically connected, which means that the magnetic terminal 104 is electrically connected to the main circuit board. At this time, if you place the smart terminal and bring the magnetic plug inserted into the smart terminal close to the magnetic terminal 104, the magnetic terminal 104 and the magnetic plug will be connected by mutual magnetic attraction and form an electrical connection, and charging will begin.

[0082] Fifth embodiment

[0083] The charging device 115 of the fifth embodiment is a charging station, which is inserted into the magnetic connection unit 117.
