[0035] Example 1

[0036] The present application embodiment provides a circuit assembly that can be applied to a near-eye display module, such as Figures 1 to 10 As shown, it includes: a plug board 1, a main control board 2, an antenna board 4, a power board 3 and a plurality of bendable flexible connecting parts 5;

[0037] The plug board 1 is configured to be electrically connected to the display assembly 11;

[0038] The main control board 2 is electrically connected to the plug-in board 1. The main control board 2 includes a first surface and a second surface arranged opposite to the first surface. The first surface is provided with a first functional circuit, and the second surface is provided with a second functional circuit. The first functional circuit and the second functional circuit are electrically connected. The first functional circuit and the second functional circuit can be different. For example, the first functional circuit includes a power supply circuit, and the second functional circuit includes a main control circuit.

[0039] The power board 3 is electrically connected to the first functional circuit and the second functional circuit of the main control board 2, and the power board is configured to allow electrical connection to the battery 304; and a flexible connection portion 5 electrically connects the plug board 1 and the main control board 2, and electrically connects the main control board 2 and the power board 3, wherein the flexible connection portion 5 is configured to allow the plug board 1, the main control board 2 and the power board 3 to be folded with each other, and the flexible connection portion 5 is also configured to allow the plug board 1, the main control board 2 and the power board 5 to be unfolded with each other.

[0040] It can be understood that during the design and production, an integrated design was carried out, and the overall circuit components are roughly arranged in a straight line. It can be understood that the antenna board 4 is relatively small in size relative to the main control board 2, and it does not affect the straight line arrangement of the plug board 1, the main control board 2, the flexible connection part 5 and the power board 3. In some embodiments, when fully expanded, the main control board 2 and the power board 3 are arranged in a straight line; when fully folded, the main control board 2 and the power board 3 are coaxially arranged. The full expansion here can be understood as pulling up under external force, and the full folding can be understood as folding under the action of external force. The flexible connection part 5 can be flexibly folded or pulled up to expand under the action of external force, so as to achieve the placement of each board.

[0041] The circuit boards such as the plug board 1, the main control board 2, the antenna board 4 and the power board 3 are integrated together to facilitate the centralized management and maintenance of the circuit components. The circuit components also include the antenna board 4, which is electrically connected to the main control board 2 through the flexible connection part 5, and the flexible connection part 5 is also configured to allow the antenna board 4 and the main control board 2 to be folded with each other, wherein the foldable angle range of the antenna board 4 relative to the main control board 2 is smaller than the foldable angle range of the power board 3 relative to the main control board 2; for example, the foldable angle range of the antenna board 4 relative to the main control board 2 can be folded clockwise or counterclockwise between 0-120°, and the total folding angle range is 240° with the rotation axis as the center for reference, and the power board 3 can be folded clockwise or counterclockwise between 0-180° with respect to the main control board 2, and the total folding angle range is 360° with the rotation axis as the center for reference. Specifically, in some embodiments of the present application, the plug board 1 and the power board 3 may be made of flexible materials; the main control board 2 is provided with power components 211 and main control components 222, which are made of rigid materials;

[0042] Exemplarily, the main control board 2 can use a glass fiber substrate or a polyimide material; wherein the glass fiber substrate is a commonly used standard substrate material with good mechanical strength and insulation performance; and polyimide is a material with good high temperature tolerance and can be used in high temperature environments.

[0043] Of course, there is no limitation on the specific material of each circuit board.

[0044] Each flexible connection part 5 is provided with a wire 51; the plug board 1 is electrically connected to the main control board 2 through the wire 51 of the flexible connection part 5; the main control board 2 is electrically connected to the power board 3 through the wire 51 of the flexible connection part 5; the main control board 2 is electrically connected to the antenna board 4 through the wire 51 of the flexible connection part 5;

[0045] The flexible connecting parts 5 enable the plug-in board 1 and the main control board 2 , the main control board 2 and the power board 3 , and the main control board 2 and the antenna board 4 to be relatively folded.

[0046] Exemplarily, the plug board 1 and the power board 3 can be folded at an angle relative to the main control board 2, for example, they can be folded to the front or back of the main control board 2, and the antenna board 4 can be folded at an angle relative to the main control board 2, for example, they can be folded to form a certain angle with the side of the main control board 2, such as a vertical angle, etc.;

[0047] Of course, there is no limitation on the specific foldable angles of the plug board 1 , the power board 3 , and the antenna board 4 .

[0048] Specifically, in some embodiments of the present application, Figure 5 , Figure 6 as well as Fig. 9 As shown, the antenna board 4 is arranged on the periphery of the main control board 2 and can be folded at an angle relative to the main control board 2. When the circuit board is stored and folded as a whole, the antenna board 4 is folded 90 degrees relative to the main control board 2, which makes full use of the vertical space of the circuit board, can effectively reduce the horizontal space occupied by the antenna board 4, can reduce the overall horizontal size of the circuit board, and when the folding angle of the antenna board 4 is 90 degrees, it can prevent the antenna set on the antenna board 4 from being surrounded or shielded by the circuit boards, which is beneficial to the antenna's signal transmission and reception.

[0049] The above design also implements the design concept of miniaturization and lightweight, which can meet users' demand for lightweight, effectively reduce the weight of smart head-mounted devices, and reduce the volume of near-eye display modules.

[0050] Specifically, in some embodiments of the present application, the overall size of the above-mentioned circuit boards is less than or equal to 1 cubic centimeter.

[0051] Furthermore, a plug socket 131 is provided on one side of the plug board 1 , and a reinforcing sheet 13 for enhancing the structural strength of the plug board 1 is provided on the other side of the plug board 1 .

[0052] Specifically, in some embodiments of the present application, Figure 5 As shown, the plug board 1 is provided with a reinforcing sheet 13 to strengthen the connection strength of the plug board 1. The reinforcing sheet 13 can be located on a side of the plug board 1 away from the socket 131, and the rigidity of the reinforcing sheet 13 is greater than the rigidity of the flexible connection part 5. For example, the reinforcing sheet 13 can be made of a rigid or hard material, such as rigid plastic, acrylic, insulating metal, etc.

[0053] The reinforcement sheet 13 can increase the strength and rigidity of the plug board 1, improve the structural stability of the plug board 1, and reduce the risk of contact failure and breakage caused by vibration, impact or other external forces.

[0054] The reinforcing sheet 13 is usually made of corrosion-resistant material and has good corrosion resistance, which can protect the plug board 1 from moisture, chemicals or other corrosive factors in the environment and extend the service life.

[0055] Furthermore, if Figures 1 to 4 As shown, one side of the main control board 2 is provided with a power circuit 21. When the circuit assembly is flat, the side of the main control board 2 provided with the power circuit 21 extends to the side of the plug board 1 provided with the plug socket 131;

[0056] A main control circuit 22 is disposed on the other side of the main control board 2 . The power supply circuit 21 and the main control circuit 22 may be located on two opposite sides of the main control board 2 .

[0057] The power circuit 21 is provided with power components 211, such as a voltage and current conversion module, etc., and the main control circuit 22 is provided with main control components 222, such as a main control unit and peripheral capacitors or resistors, etc.;

[0058] When the plug board 1 and the main control board 2 are folded, the higher power component 211 is located outside the projection range of the protective cover 112 on the main control board 2 and is not stacked with the protective cover 112; this can effectively reduce the overall height of the stacked circuit components and make the thickness of the stacked circuit components as small as possible.

[0059] Exemplarily, the main control components 222 provided on the main control circuit 22 may include: a brain network main control chip, a crystal oscillator, a resistor, a capacitor and other peripheral devices to realize the control function.

[0060] The above-mentioned design of the position relationship between the main control circuit 22 and the power circuit 21 places the main control circuit 22 and the power circuit 21 on the electrical path closest to the display assembly 11, which can prevent the power circuit 21 and the control circuit from being too far away from the display assembly 11, thereby reducing the adverse interference caused by the electrical path being too far away;

[0061] In addition, the plug board 1, the main control board 2, the power board 3 and the battery 304 are stacked, which effectively reduces the overall size, and the power board 3 is not provided with any components, so that it is not easy to produce a short circuit when stacked. It can be understood that in some embodiments, when the plug board 1, the main control board 2, the power board 3 and the antenna board 4 are in the first folding state, the plug board 1, the main control board 2 and the power board 3 are stacked in sequence, and the first folding state can be a folding state after the installation position is determined, the plug board 1, the main control board 2 and the power board 3 are parallel to each other, and the antenna board 4 is perpendicular to the main control board 2 and / or the power board 3, that is, after folding, the antenna board 4 is at an angle of 90° relative to the main control board 2, and the side of the power board 3 facing the main control board 2 is not provided with components and is electrically isolated from the main control board 2, and the side of the power board 3 away from the main control board 2 is provided with polarity contacts. Moreover, the main control chip on the main control circuit 22 has a larger projection area, and the main control components 222 on the main control board 2 often need to occupy a larger area of ​​the main control board 2. Therefore, the main control circuit 22 and the power supply circuit 21 of the main control board 2 are respectively arranged on the two sides of the main control board 2, and the main control circuit 22 is arranged on the side away from the protective cover 112. This can avoid the stacking of electronic components in height, and can effectively compress the volume of the circuit board after folding, thereby achieving lightweight and miniaturized design requirements.

[0062] Furthermore, if Figure 1 as well as Figure 3 As shown, a first polarity contact 301 and a second polarity contact 302 are provided on one side of the power board 3; one of the first polarity contact 301 and the second polarity contact 302 corresponds to the positive pole, and the other of the two corresponds to the negative pole;

[0063] When the circuit assembly is flattened, the side of the power board 3 provided with the first polarity contact 301 and the second polarity contact 302 extends to the side of the plug board 1 provided with the plug socket 131;

[0064] Usually, two power boards 3 need to be provided; and the power board 3 needs to occupy a certain space.

[0065] The first polarity contact 301 and the second polarity contact 302 are arranged on the same surface of the power board 3, the first polarity contact and the second polarity contact are electrically connected to the first functional circuit and the second functional circuit, and the first polarity contact and the second polarity contact are configured to be electrically connected to the battery, and only one power board 3 is needed, which reduces the use of the power board 3, saves the use of space, makes the design more compact, and further reduces the thickness and size of the overall circuit assembly after folding;

[0066] The manufacturing cost can also be reduced by reducing the use of one power board 3. However, the corresponding battery 304 needs to have a positive electrode and a negative electrode on the same side, and the battery can be a button battery or the like.

[0067] The other side of the power board 3 is a planar structure. The planar structure and the design without electronic components can avoid the short circuit problem that may occur when stacking;

[0068] Secondly, the planar structure can also reduce the wear and scratching of the second surface of the power board 3 on the main control components 222, thereby extending the service life of the main control components 222.

[0069] Furthermore, if Figures 1 to 4 , Figure 7 and Figure 8 As shown, the antenna board 4 is arranged on one side of the main control board 2 close to the power board 3; the design of the position of the antenna board 4 on the main control board 2 is helpful to avoid interference between the flexible connection part 5 connecting the plug board 1 and the main control board 2 and the flexible connection part 5 connecting the main control board 2 and the antenna board 4 to a certain extent, so as to prevent the normal folding of the circuit components from being affected;

[0070] A socket 131 for electrically connecting the display assembly 11 is provided on the plug board 1. The circuits or components existing in the display assembly 11 itself may generate electromagnetic interference to the antenna. By setting the antenna board 4 on the side close to the power board 3, it can actually be away from the display assembly 11 set on the plug board 1, thereby optimizing the antenna signal transmission effect.

[0071] The present application also provides a near-eye display module, such as Figure 5 , Figure 6 As shown, it includes the above-mentioned circuit component and display component 11,

[0072] The display component 11 includes a microdisplay 111 and a plug 113 matching the socket 131; the microdisplay 111 is electrically connected to the plug 113; the microdisplay includes but is not limited to Micro-LED (Micro Light-Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing) or LBS (Laser Beam Scanning), etc., or any combination of these technologies.

[0073] The microdisplay 111 is connected to the plug board 1 by connecting the plug 113 with the socket 131. The microdisplay 111 is arranged on a side of the plug board 1 away from the socket 131. A protective cover 112 is arranged at a corresponding position of the plug 113. For example, the protective cover 112 can be arranged on the back side of the plug 113. A microcontrol circuit electrically connected to the microdisplay 111 is arranged inside the protective cover 112, etc.

[0074] The above design can reduce the overall size of the device, save space, and be more compact.

[0075] Furthermore, the length of the flexible connection portion 5 for connecting the plug board 1 and the main control board 2 is greater than the sum of the thicknesses of the power circuit 21, the power board 3, and the protective cover 112;

[0076] The thickness of the power circuit 21 mainly comes from the power components 211;

[0077] The length of the flexible connection part 5 for connecting the main control board 2 and the power board 3 is greater than the sum of the thickness of the main control circuit 22 and the main control board 2;

[0078] The thickness of the main control circuit 22 mainly comes from the main control components 222;

[0079] The length of the flexible connection part 5 for connecting the plug board 1 and the main control board 2 is greater than the length of the flexible connection part 5 for connecting the main control board 2 and the power board 3 .

[0080] By making the length of the flexible connection part 5 exceed the sum of the thicknesses of the connected circuit and the plate, the stability and reliability of the connection can be ensured; problems such as stretching, breakage or poor contact caused by the flexible connection part 5 being too short can be avoided, thereby improving the reliability of the system.

[0081] The longer length of the flexible connection part 5 can provide a larger bending radius and movable space, which can make the connection between the plug board 1, the main control board 2 and the power board 3 more flexible and adapt to different installation environments and layout requirements; it can also reduce the stress and pressure on the flexible connection part 5 and reduce the damage and wear caused by bending and movement.

[0082] Furthermore, if Figure 6 As shown, the near-eye display module further includes a battery 304, a base plate 33 and a housing 34;

[0083] The power board 3 is connected to the battery 304;

[0084] The bottom plate 33 and the housing 34 form a receiving space 313, and the folded circuit assembly, the display assembly 11 and the battery 304 are all arranged in the receiving space 313

[0085] The use of the base plate 33 and the housing 34 can effectively protect the circuit components from the influence of the external environment, such as dust, moisture, shock, etc.;

[0086] The bottom plate 33 and the housing 34 can not only protect the circuit assembly, but also provide mechanical support for the circuit assembly; this helps to strengthen the structural strength of the circuit assembly and improve its durability.

[0087] By using the bottom plate 33 and the shell 34 for packaging, when maintenance or replacement is required, the shell 34 can be opened and the circuit component can be folded out from the bottom plate 33, which is convenient for maintenance and replacement.

[0088] After the plug board 1, the main control board 2, the power board 3, and the antenna board 4 are folded in space, they can be packaged together, realizing the stacking setting between the circuit boards, compressing the volume space occupied by the circuit boards, and effectively reducing the impact of multiple circuit boards in terms of size, and all electrical components can be electrically connected to the display assembly 11, so that the display assembly 11 can work independently in a sufficiently small size.

[0089] Specifically, in some embodiments of the present application, the diameters of the plug board 1, the main control board 2, the power board 3, and the antenna board 4 are less than or equal to 10 mm.

[0090] The maximum size of the plug board 1, the main control board 2, the power board 3, and the antenna board 4 is less than or equal to 10 mm. For example, when the main control board 2 and the power board 3 are circular, the size can be the diameter, and if they are rectangular or square, it can be the diagonal length. Each circuit board has a miniaturized design in size, and all circuit boards are designed as an electrically connected whole, which can be folded and then assembled in a shell together with the battery 304 to achieve packaging, thereby achieving higher assembly efficiency.

[0091] Among them, the size of the plug board 1 is smaller than that of other circuit boards, and the sizes of the main control board 2 and the power board 3 are the same. In the folded state, the circuit boards can be arranged in parallel. In other embodiments, the number of electrical components (such as positive and negative electrodes) of the power board 3 is much less than the number of electrical components (such as control chips, capacitors, resistors, inductors, etc.) of the main control board 2, so the size of the main control board 2 can be larger than that of the power board 3, which can further reduce the material of the circuit board and reduce the overall weight.

[0092] The embodiments of the present application have at least the following beneficial effects:

[0093] A flexible connection part 5 is provided between the plug board 1, the main control board 2, the antenna board 4 and the power board 3, realizing an integrated design. The circuit boards can be flipped and folded relative to each other, effectively reducing the overall space occupied by the circuit components, and having the characteristics of lightweight and miniaturization; a design to avoid thickness stacking is adopted, so that the thickness of the circuit boards after stacking is as small as possible.

[0094] Example 2

[0095] The present application embodiment provides a circuit component, such as Figure 7 and Figure 8 As shown, it includes: a plug board 1, a main control board 2, an antenna board 4, a power board 3 and a plurality of bendable flexible connecting parts 5;

[0096] A first polarity contact 301 is provided on the first surface of the power board 3, and a second polarity contact 302 is provided on the side wall 32 of the power board 3;

[0097] One of the first polarity contact 301 and the second polarity contact 302 corresponds to the positive pole, and the other corresponds to the negative pole.

[0098] Optionally, the first polarity contact 301 may correspond to the positive pole or the negative pole, and the second polarity contact 302 may correspond to the negative pole or the positive pole, and the corresponding relationship between the first polarity contact 301 and the second polarity contact 302 is not limited.
