Description

Technical Field

[0001] This invention relates to micromechanics, and more specifically to a self-reconfigurable magnetic connection device. Background Technology

[0002] Existing magnetic connectors typically consist of a male and a female connector module, including components such as a circuit board, a male connector, a female connector, and a permanent magnet. When the male and female connector modules are close enough, they are attracted together by the permanent magnet, resulting in tight contact between the male and female connectors and an electrical connection. However, when the male and female connector modules need to be separated, manual pulling is required to separate them, and automatic separation is not possible.

[0003] The most common magnetic connection device on the market consists of only two permanent magnets and an electrical connector. It can be connected relatively easily; however, it requires external assistance, and more often than not, manual assistance, which is inconvenient and cannot achieve automatic control in some situations.

[0004] Compared to traditional magnetic connection devices, the purpose of this invention is to achieve electric control of the connection or separation of magnetic connection devices within a limited space. Summary of the Invention

[0005] In view of the shortcomings of existing magnetic connectors that can only be manually plugged in and unplugged and cannot be automatically reconfigured, the advantages of this invention are that it controls the connection or separation of two components in a simple electric manner. The device has the advantages of small size, simple control and automatic positioning.

[0006] A self-reconfigurable magnetic connection device is disclosed, comprising a self-reconfigurable magnetic connection module and an external magnetic connection module connected by magnetic attraction. The self-reconfigurable magnetic connection module and the external magnetic connection module are respectively provided with a first electrical connection component and a second electrical connection component. After the self-reconfigurable magnetic connection module and the external magnetic connection module are magnetically connected, the first electrical connection component and the second electrical connection component are electrically connected.

[0007] The self-reconfigurable magnetic connection module is equipped with a rotatable magnetic roller, a first magnet is installed on the magnetic roller, and a second magnet is provided on the external magnetic connection module. By rotating the magnetic roller, the orientation of the first magnet is changed, so that the external magnetic connection module is magnetically attached to the self-reconfigurable magnetic connection module, or the external magnetic connection module that is magnetically attached to the self-reconfigurable magnetic connection module is detached.

[0008] Furthermore, the self-reconfigurable magnetic connection module includes a base and a housing assembled together, with a synchronous belt drive mechanism or a worm gear drive mechanism installed inside the housing to drive the magnetic roller to rotate.

[0009] Furthermore, the synchronous belt drive mechanism includes an electric slide table and a synchronous belt;

[0010] The electric slide table is mounted on the base. The electric slide table is equipped with a working slide table, a slide table motor, and a screw. The screw is mounted on the rotating shaft of the slide table motor, and the working slide table is provided with a threaded hole that mates with the screw.

[0011] The synchronous belt is mounted horizontally on the base, and one side of the synchronous belt is connected to the electric slide base.

[0012] The synchronous belt is engaged with at least one magnetic roller, the position of which corresponds to the position of the second magnet on the external magnetic connection module. The magnetic roller is provided with at least one self-rotating roller vertically mounted on the base. The roller is provided with a synchronous pulley that engages with the synchronous belt, and a strip-shaped first magnet is mounted on the roller.

[0013] The slide motor drives the screw to rotate, causing the working slide to move linearly. The working slide drives the synchronous belt to rotate, and the synchronous belt drives the roller to rotate, thereby changing the orientation of the first magnet on the roller.

[0014] Furthermore, the electric slide table also includes an electric slide table base, which has a motor slide table base fixing hole for connecting with the base, and a smooth rod parallel to the screw is also fixed on the electric slide table base.

[0015] The working slide has parallel threaded holes and through holes, through which the screw and the smooth rod pass respectively;

[0016] The slide table motor is an internal rotor motor, and its housing is fixedly connected to the electric slide table base.

[0017] Furthermore, the worm gear drive mechanism includes a geared motor, a driving gear, a driven gear, a rotating shaft, a worm, and a worm wheel;

[0018] The geared motor is horizontally mounted on a base. A rotating shaft is installed on one side of the geared motor, and a driven gear is fixed on the rotating shaft. The driven gear meshes with the driving gear on the output shaft of the geared motor.

[0019] A worm gear is provided on the rotating shaft, and a worm wheel that meshes with the worm gear is provided on the magnetic roller.

[0020] Furthermore, the outer casing is equipped with two magnetic rollers, and a synchronous belt drive mechanism or a worm gear drive mechanism simultaneously drives the two magnetic rollers to rotate.

[0021] The first magnets on the two magnetic rollers face the same direction, and the opposing surfaces between the first and second magnets are strong magnetic surfaces with opposite polarities.

[0022] Furthermore, a lower bearing groove and an upper bearing groove are respectively provided on the upper surface of the base and the top surface inside the outer shell, and a lower bearing and an upper bearing are respectively installed in the lower bearing groove and the upper bearing groove.

[0023] The magnetic roller has an upper boss and a lower boss at both ends, which pass through the center holes of the lower bearing and the upper bearing respectively and are fixed.

[0024] Furthermore, the external magnetic connection module has a base plate with a magnetic groove for fixing the second magnet.

[0025] Furthermore, the first electrical connection component includes a first main circuit board and a first female connector pin; wherein,

[0026] The first main circuit board is mounted on the base, and several spring contacts are provided on one side of the first main circuit board. The bottom end of the first female socket pin is disc-shaped, and the middle part is a cylinder with a relatively thin diameter. The top end of the first female socket pin is a metal pin with an indented groove. The first female socket pin passes through the through hole opened in the outer shell and is fixed. When the outer shell and the base are installed in place, the spring contacts and the first female socket pin contact and press against each other to achieve electrical connection; or

[0027] The first electrical connection component includes a second main circuit board and a front circuit board. The second main circuit board is mounted on the base, and the second female connector pin is directly soldered to the front circuit board and fixed to the housing through the through hole opened in the housing. The main circuit board connector and the front circuit board connector are respectively mounted on the second main circuit board and the front circuit board connector. The main circuit board connector and the front circuit board connector are electrically connected to each other through a ribbon cable.

[0028] Furthermore, the second electrical connection component is provided with a sub-circuit board mounted on the base plate. At one end of the sub-circuit board, there are several contact-type elastic connectors. When the external magnetic connection module is magnetically attracted to the self-reconfigurable magnetic connection module, the elastic connectors contact and electrically connect with the first female socket pin or the second female socket pin.

[0029] The external magnetic connection module can be equipped with any one or more actuators, sensors, and displays connected to the sub-circuit board.

[0030] The advantages of this invention are:

[0031] 1) Implementation of the self-reconfigurable magnetic connection device: The magnetic roller is rotated by electric means to change the direction of the magnetic field, thereby controlling the connection or separation of the self-reconfigurable magnetic connection module from the external magnetic connection module.

[0032] 2) This invention does not require the design of complex circuits. By using a simple DC geared motor or electric slide as a power source and selecting a belt drive, gear drive or worm gear drive mechanism, combined with the design of a corresponding magnetic roller, the connection and separation of the self-reconfigurable magnetic connection module and the external magnetic connection module, as well as electrical connection and communication, can be realized. This results in lower cost, smaller size, lower energy consumption and higher efficiency.

[0033] 3) The use of a pair of magnetic rollers and a pair of second magnets can limit the degrees of freedom of the external magnetic connection module. Furthermore, the invention separates the components by rotating the magnets, requiring less force (torque), and has great application potential in micro-electromechanical products, children's toys, and intelligent robots.

[0034] 4) In the first electrical connection component of the self-reconfigurable magnetic connection module, a spring is welded on the horizontally placed main circuit board to achieve electrical connection with the vertically placed female pin. When the outer shell and base of the self-reconfigurable magnetic connection module are installed in place, the spring and the female pin press against each other and make contact to achieve a stable electrical connection; or the female pin is welded on the vertically placed front circuit board, and then the front circuit board and the horizontally placed main circuit board are connected by a ribbon cable, which has stronger assemblability.

Detailed Implementation

[0055] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0056] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0057] This invention provides a self-reconfigurable magnetic connection device, including a self-reconfigurable magnetic connection module 1 and an external magnetic connection module 2. The self-reconfigurable magnetic connection module 1 and the external magnetic connection module 2 are respectively provided with a first electrical connection component 3a and a second electrical connection component 3b. When the self-reconfigurable magnetic connection module 1 and the external magnetic connection module 2 are magnetically attracted, the first electrical connection component 3a and the second electrical connection component 3b are accurately connected, achieving electrical conductivity. Figure 1 and Figure 2 As shown.

[0058] Example 1

[0059] To facilitate manufacturing and assembly, the self-reconfigurable magnetic connection device 1 in this invention is designed to consist of a housing 11, a base 12, an electric slide 13, a synchronous belt 14, a pair of magnetic rollers 15, a pair of upper bearings 16, a pair of lower bearings 17, and slide bolts 18, etc. Figure 3 In this embodiment, a pair of magnetic rollers 15 are driven to rotate by a synchronous belt drive mechanism.

[0060] The following is combined with Figures 3-11 The structure of the self-reconfigurable magnetic connection module 1 will be further explained below:

[0061] The magnetic roller 15 consists of five parts: a roller 151, an upper boss 152, a lower boss 153, a synchronous pulley 154, and a first magnet 155. The roller 151 is preferably cylindrical, with a rectangular groove cut into its side wall, and the first magnet 155 is embedded within the groove. A synchronous pulley 154 is designed at one end of the roller, fixed to the roller 151 and preventing relative movement. Figure 4 .

[0062] The first magnet 155 is required to have its exposed side of the roller 151, visible after assembly, as either its N or S pole. Preferably, the two first magnets 155 within the same self-reconfigurable magnetic connection module 1 have opposite polarities on the exposed roller 151. This provides a foolproof connection between the self-reconfigurable magnetic connection module 1 and the external magnetic connection module 2. Figure 4 .

[0063] To ensure smooth rotation of the magnetic roller 15 along its axis, an upper boss 152 and a lower boss 153 can be added to both ends, such as... Figure 4 The upper bearing 16 is installed and connected to the housing 11, and the lower bearing 17 is installed and connected to the base 12, as follows. Figure 3 .

[0064] The synchronous belt 14 meshes with the synchronous pulley 154 of a pair of magnetic rollers 15, ensuring that the pair of magnetic rollers 15 can rotate around their respective axes in the same direction and at the same speed; and during assembly, the installation direction of the magnetic rollers needs to be adjusted to ensure that the first magnet 155 faces the same direction, such as... Figure 3 .

[0065] To drive the magnetic roller to rotate along the axis, a suitable power unit is needed. In this embodiment, an electric slide table 13 is used to achieve the corresponding function.

[0066] The electric slide table 13 consists of an electric slide table base 131, a slide table motor 132, a motor slide table base fixing hole 133, a working slide table 134, a screw 135, and a guide shaft 136. The electric slide table base 131 has a motor slide table base fixing hole 133 for easy connection to the base 12 via slide table bolts. The slide table motor 132 is an internal rotor motor, and its housing is fixed to the electric slide table base 132. One end of the screw 135 is connected to the slide table motor 132, and the other end is connected to the side wall of the electric slide table base 131, allowing only rotation around its axis. The guide shaft 136 is fixed parallel to the screw 135 on the electric slide table base 131. The working slide table 134 has parallel threaded holes and through holes, through which the screw 135 and the guide shaft 136 pass, respectively. When the slide table motor 132 operates, the screw 135 rotates, driving the working slide table 134 to move along the axial direction of the guide shaft. Figure 5 .

[0067] The working slide 134 has a structure protruding from the electric slide base 131 on its side for fixed connection with the timing belt 14. In this example of the invention, UV adhesive is used to fix the working slide 134 and the timing belt 14. To ensure a tight connection, the UV adhesive covers at least two teeth of the timing belt 14, such as... Figure 6 .

[0068] The outer casing 11 consists of a roller groove 111, an upper bearing groove 112, and a casing through hole 113. The roller groove 111 accommodates the magnetic roller 15, facilitating alignment during structural assembly. The upper bearing groove 112 accommodates the upper bearing 16, which, while limiting the position of the magnetic roller 15, also ensures smooth rolling of the magnetic roller 15. Figure 7 .

[0069] The base 12 is designed with a lower end bearing groove 121, a slide table fixing hole 122, and a circuit board fixing hole 123. The lower end bearing groove 121 is used to install the lower end bearing 17, thereby limiting the position of the magnetic roller 15; the slide table fixing hole 122 is used to fix the electric slide table 13, such as... Figure 8 When the self-reconfigurable magnetic connection device requires electrical connection functionality, the circuit board mounting holes are used to secure the corresponding circuit board, such as... Figure 9 .

[0070] Based on the connection and cooperation of the above components, the self-reconfigurable magnetic connection module 1 can selectively expose its magnetism to the outside. For example... Figure 10 When the working slide 134 is located in the position shown on the left, the magnetic side of the first magnet 155 in the magnetic roller 15 is parallel to the contact surface of the external magnetic connection module 2, exposing its magnetism to the outside; as Figure 11When the working slide 134 moves to the right in the diagram, it drives the synchronous belt 14 to rotate clockwise, which in turn drives a pair of magnetic rollers 15 to rotate clockwise. When the magnetic rollers 15 rotate 90 degrees clockwise, the magnetic side of the first magnet 155 is perpendicular to the contact surface of the external magnetic connection module 2, and its magnetism is not exposed. At this time, when the working slide 134 moves to the left in the diagram, it drives the synchronous belt 14 to rotate counterclockwise, which in turn drives a pair of magnetic rollers 15 to rotate counterclockwise. When the magnetic rollers 15 rotate 90 degrees counterclockwise, the magnetic side of the first magnet 155 is parallel to the contact surface of the external magnetic connection module 2, and its magnetism is exposed.

[0071] Please refer to the following: Figures 12-13 The structure of the external magnetic connection module 2 will be further explained below:

[0072] The external magnetic connection module 2 is designed with a base plate 21, a magnet groove 22, and an external module through hole 24, and a second magnet 23 is embedded therein. In this embodiment of the invention, the magnet groove 22 is designed as a boss to limit the position of the second magnet 23 and facilitate fixed connection. The direction of the second magnet 23 facing the magnet groove is the magnetization direction. During installation, it is ensured that the polarity of the side of the second magnet 23 facing the inside of the magnet groove 22 is opposite to the polarity of the side of the corresponding first magnet 155 exposed on the roller 151, so that the first magnet 155 and the second magnet 23 at corresponding positions can attract each other. The external module through hole 24 is used for the passage of related electrical connection components, such as... Figure 12 , Figure 13 .

[0073] The external magnetic connection module 2 can function as an actuator, sensor, and display. When used as an actuator, it can be configured with components such as motors, servos, relays, and buzzers. When used as a sensor, it can be configured with components such as ultrasonic ranging devices, TOF laser ranging devices, photoresistors, photodiodes, tactile switches, reed switches, photoelectric switches, microphones, and cameras. When used as a display, it can be configured with components such as LEDs, lasers, e-ink screens, LCDs, and OLEDs. The external magnetic connection module 2 can also be configured with multiple components to achieve richer functionality.

[0074] To highlight its main function, the external magnetic connection module 2 of this invention only shows the side that is magnetically connected to the self-reconfigurable magnetic connection module 1. A plane, support, or wheels can be added to the bottom of the base plate 21 of this external magnetic connection module 2 to ensure that it can be placed vertically and will not tip over.

[0075] Based on the above design, the self-reconfigurable magnetic connection module 1 and the external magnetic connection module 2 can be tightly connected when needed and quickly disconnected when not needed.

[0076] Example 2

[0077] This invention provides another embodiment of a self-reconfigurable magnetic connection module, whose internal structure includes an electrical connection component 4 and a magnetic drive module 5. In this embodiment, the two magnetic rollers 57 are driven to rotate via gear transmission and worm gear transmission.

[0078] like Figure 16 and Figure 17 In this embodiment, the magnetic drive module 5 achieves the rotation of the magnetic roller through gear transmission and worm gear transmission. For ease of manufacturing and assembly, the magnetic drive module 5 includes a reduction motor 51, a driving gear 52, a driven gear 53, a rotating shaft 54, a worm 55, a worm wheel 56, a magnetic roller 57, and a support structure 58.

[0079] The driving gear 52 and driven gear 53 mesh together. The driven gear 53 and two worms 55 are fixed to the rotating shaft 54. The two worms 55 mesh with two worm wheels 56 respectively, and the two worm wheels 56 are fixed with two magnetic rollers 57 respectively. The main body of the geared motor 51 is fixed by the support structure 58, and the rotating shaft 54 ​​also passes horizontally through the hole in the support structure 58.

[0080] After receiving the control signal from the second main circuit board 41, the geared motor 51 operates, driving the drive gear 52 fixed on its output shaft to rotate, which in turn drives the driven gear 53, the rotating shaft 54 ​​and the two worm gears 55 to rotate together, thereby driving the two worm wheels 56 together with the two magnetic rollers 57 to rotate in the same direction.

[0081] By precisely controlling the speed and rotation time of the geared motor 51, designing a reasonable limit structure, or adding a magnetic sensor or rotation angle sensor, the rotation direction of the magnetic roller can be precisely controlled, ultimately achieving the expected effect of mutual magnetic connection or separation between the self-reconfigurable magnetic connection module and the external magnetic connection module.

[0082] The advantages of this embodiment are: using a gear and worm gear transmission structure, the expected effect of mutual magnetic connection or separation between the self-reconfigurable magnetic connection module and the external magnetic connection module can be achieved, and the size is more compact, and there are also certain advantages in manufacturing and assembly.

[0083] In this invention, the connection forms of the two electrical connection components are varied, including but not limited to contact connection, ribbon cable connection, plug-in connection, wire welding connection, etc. The structure of the two electrical connection components designed in the accompanying drawings will be further described below.

[0084] Example 3

[0085] Reference Figures 1-13 As shown, the electrical connection component includes a first electrical connection component 3a and a second electrical connection component 3b. The structure of the first electrical connection component 3a and the second electrical connection component 3b will be further described below:

[0086] The first electrical connection component 3a consists of a first main circuit board 31, a spring 32, and a first female socket pin 33, while the second electrical connection component 3b consists of a secondary circuit board 34 and a flexible connector 35.

[0087] The first main circuit board 31 is fixed to the base 12 by circuit board bolts 19, and a spring piece 32 is welded to the front edge of the main circuit board. The first female socket pin 33 is preferably a metal pin with a disc-shaped bottom, a relatively thin cylinder in the middle, and a recessed groove at the top. After the first female socket pin 33 passes through the housing through hole 113, it is bonded to the housing 11. When the housing 11 and the base 12 are spliced ​​together, the spring piece 32 contacts the first female socket pin 33 and presses against each other to achieve a stable electrical connection.

[0088] The sub-circuit board 34 is fixed on the external magnetic connection module 2. The side with the elastic connector 35 soldered on faces the direction of magnetic connection. After the elastic connector 35 passes through the external module through hole 24, its elastic connection part needs to have a certain protruding surface.

[0089] The present invention uses 6 pairs of springs 32, first female socket pins 33 and elastic connectors 35. However, according to the present invention, any number of springs 32, first female socket pins 33 and elastic connectors 35 can be realized within the size and magnetic strength limitations to achieve stable power supply, signal and other electrical connections.

[0090] Example 4

[0091] like Figure 14 and Figure 15 The electrical connection components include a second main circuit board 41 (equivalent to the first main circuit board 31 in Embodiment 3) and a front circuit board 43 (functionally equivalent to the first female connector pin 33 in Embodiment 3). The second main circuit board 41 is horizontally mounted and has components such as a microcontroller designed on it to control various functions of the self-reconfigurable magnetic connection module 1. The front circuit board 43 is vertically fixed to the inner wall of the outer shell of the magnetic surface of the self-reconfigurable magnetic connection device, and several second female connector pins 45 are mounted on it to achieve electrical connection between the self-reconfigurable magnetic connection module 1 and the external magnetic connection module 2. A main circuit board connector 42 and a front circuit board connector 44 are respectively mounted on the second main circuit board 41 and the front circuit board 43, and electrical connection between the two can be achieved through methods such as ribbon cables.
