Description

Technical Field

[0001] This utility model patent relates to the technical field of dual-control reader / writer, and more specifically, to the hinge structure of a dual-control reader / writer. Background Technology

[0002] A reading and writing station can project desktop content into the air from a distance, realizing the transformation from "near-viewing" to "far-viewing," that is, a device that uses optical means to extend near-distance reading and writing to far-distance imaging.

[0003] Currently, to facilitate the use and storage of reading and writing desks, these desks are designed with a folding function. For example, a prior patent with publication number CN119439466A discloses a desktop far-image reading and writing device, including a far-image optical system, a distance sensor, a controller, and a display device. The far-image optical system includes a planar beam splitter and a first concave reflector. Light reflected from the desktop and objects placed on it is directed from below to the planar beam splitter, where it is split to form a first ray. This first ray is then reflected by the first concave reflector and directed through the planar beam splitter to the exit pupil, forming a virtual image at least three meters in front of the exit pupil. The distance sensor is used to collect the distance d from the bottom of the desktop far-image reading and writing device to the desktop or objects placed on it. The controller obtains the virtual image distance l' of the far-image optical system based on the distance d from the bottom of the desktop far-image reading and writing device to the desktop or objects placed on it, and displays the virtual image distance l' through the display device.

[0004] In the prior art, when the reader / writer is in use, the concave mirror cover and the support plate are difficult to maintain a stable perpendicular position, and the self-locking effect of the concave mirror cover is poor, which affects the normal use of the reader / writer. Utility Model Content

[0005] The purpose of this invention is to provide a hinge structure for a dual-control reading and writing table, which aims to solve the problem of poor self-locking effect of the concave mirror cover of the reading and writing table in the prior art.

[0006] This utility model is implemented as follows: a dual-control reader / writer hinge structure includes a concave mirror cover, a screen panel, a rear cover, and a hinge assembly. The hinge assembly includes a main shaft, a rear retaining plate, a cover hinge module, and a plate hinge module. The rear retaining plate, the cover hinge module, and the plate hinge module are respectively assembled with the main shaft. The rear retaining plate is assembled with the rear cover.

The plate hinge module is assembled with the screen panel and applies a locking force to the screen panel. The concave mirror cover and the screen panel are oscillating relative to the rear cover under external force.

[0007] Furthermore, the cover hinge module includes a cover fixing plate, a cover compression spring, and a cover pressure guiding assembly. The main shaft synchronously passes through the cover fixing plate, the cover compression spring, and the cover pressure guiding assembly. One end of the cover compression spring is fixed, and the other end of the cover compression spring is assembled with the cover pressure guiding assembly. The cover fixing plate is assembled with the concave mirror cover. The concave mirror cover swings under external force, causing the cover fixing plate to swing relative to the main shaft. The swinging of the cover fixing plate is used to apply an axial thrust to the cover pressure guiding assembly. The cover pressure guiding assembly is used to compress the cover compression spring or move under the restoring force of the cover compression spring to apply a locking force to the cover fixing plate.

[0008] Furthermore, the cover pressure guiding assembly includes a first cover guide ring and a second cover guide ring, which are arranged correspondingly. The first cover guide ring is assembled with the cover compression spring in a mating arrangement. The cover fixing plate swings under force to drive the second cover guide ring to rotate relative to the first cover guide ring. The rotation of the second cover guide ring drives the first cover guide ring to move axially.

[0009] Furthermore, the second cover guide ring is stacked and assembled with the cover fixing plate; or, the second cover guide ring includes a cover main ring and an outer edge portion, the cover main ring and the outer edge portion are mated together, and the outer edge portion extends outward along the radial direction of the cover main ring, the outer edge portion is assembled with the cover fixing plate, the cover fixing plate swings to drive the outer edge portion to swing, the outer edge portion swings to drive the cover main ring to rotate, and the cover main ring rotates to push the first cover guide ring to move axially.

[0010] Furthermore, the cover hinge module includes a cover locking plate, which has a cover locking block. The cover locking plate is located between the second cover guide ring and the cover fixing plate, and the cover locking plate and the second cover guide ring are arranged in an overlapping assembly. The cover locking plate and the cover fixing plate are arranged in a movable abutting arrangement. The cover fixing plate has a cover fixing block, which is arranged in abutting or separate arrangement from the cover locking block. When the cover fixing block and the cover locking block are in abutting arrangement, the cover fixing plate is rotated by force, which causes the cover locking plate to rotate. The rotation of the cover locking plate causes the second cover guide ring to rotate.

[0011] Furthermore, the cover hinge module includes at least one cover pad, which is elastically arranged in a direction away from the cover pressure guiding assembly. The cover fixing plate has a cover fixing surface, and the cover pad and the cover fixing surface are arranged in an overlapping and abutting arrangement. The cover pad is used to buffer the cover fixing plate.

[0012] Furthermore, the main shaft has a split-shaft plate, which is located between the rear fixing plate and the cover plate, and the rear fixing plate and the cover plate clamp the split-shaft plate.

[0013] Furthermore, the cover plate includes a main cover plate and a cover ring, the main cover plate and the cover ring are assembled together, the main shaft is movably assembled with the cover ring, and the main cover plate is stacked with the concave mirror cover; the two ends of the main cover plate respectively form an upper edge plate and a lower edge plate, the upper edge plate and the lower edge plate are respectively extended in opposite directions, the cover ring is assembled together with the lower edge plate, and the upper edge plate is used to embed and position the concave mirror cover.

[0014] Furthermore, the plate hinge module includes a plate fixing plate, a plate compression spring, and a plate pressure guiding assembly. The main shaft synchronously passes through the plate fixing plate, the plate compression spring, and the plate pressure guiding assembly. One end of the plate compression spring is fixed, and the other end of the plate compression spring is assembled with the plate pressure guiding assembly. The plate fixing plate is assembled with the screen panel. The screen panel swings under external force, causing the plate fixing plate to swing relative to the main shaft.

[0015] Furthermore, the plate pressure guiding assembly includes a first plate guide ring and a second plate guide ring, which are arranged correspondingly. The first plate guide ring is assembled with the plate compression spring in a mating arrangement. The plate fixing plate swings under force to drive the second plate guide ring to rotate relative to the first plate guide ring. The rotation of the second plate guide ring drives the first plate guide ring to move axially. The second plate guide ring has a fixing plate segment that extends outward and is either embedded or separated from the plate fixing plate.

[0016] Compared with the prior art, the dual-control reading and writing table hinge structure provided by this utility model allows the concave mirror cover and screen panel to swing relative to the rear cover under the action of the hinge assembly during storage, until the concave mirror cover and screen panel are respectively overlapped with the rear cover, facilitating the storage of the reading and writing table.

[0021] Reference Figure 1-8 The image shown is a preferred embodiment of the present invention.

[0022] The dual-control reading and writing station hinge structure includes a concave mirror cover 2, a screen panel 3, a rear cover 4, and a hinge assembly 1. The hinge assembly 1 includes a main shaft 11, a rear fixing plate 12, a cover hinge module 13, and a plate hinge module 14. The rear fixing plate 12, the cover hinge module 13, and the plate hinge module 14 are respectively assembled with the main shaft 11. The rear fixing plate 12 is used to be assembled with the rear cover 4. The cover hinge module 13 is used to be assembled with the concave mirror cover 2 and applies a locking force to the concave mirror cover 2. The plate hinge module 14 is used to be assembled with the screen panel 3 and applies a locking force to the screen panel 3. The concave mirror cover 2 and the screen panel 3 are swinging relative to the rear cover 4 under external force.

[0023] The aforementioned dual-control reader hinge structure allows the concave mirror cover 2 and screen panel 3 to swing relative to the rear cover 4 under the action of the hinge assembly 1 during storage, until they overlap with the rear cover 4, facilitating storage. During use, a force is applied to the concave mirror cover 2 and screen panel 3, causing them to unfold relative to the rear cover 4, enabling the reader to be used. Simultaneously, as the concave mirror cover 2 unfolds, the cover hinge module 13 is gradually compressed. After the concave mirror cover 2 is fully unfolded, the external force is removed, and the cover hinge module 13 resets and applies a reverse force to the concave mirror cover 2, achieving self-locking of the concave mirror cover 2, limiting accidental rotation, and ensuring the concave mirror cover 2 remains stably unfolded in a horizontal position, facilitating the use of the reader.

[0024] Furthermore, the hinged structure of the reader reduces the aging of parts caused by switching between unfolded and folded states, thus extending the service life of the reader.

[0025] The cover hinge module 13 includes a cover fixing plate 131, a cover compression spring 132, and a cover pressure guiding assembly 133. The main shaft 11 passes through the cover fixing plate 131, the cover compression spring 132, and the cover pressure guiding assembly 133 simultaneously. One end of the cover compression spring 132 is fixed, and the other end of the cover compression spring 132 is assembled with the cover pressure guiding assembly 133. The cover fixing plate 131 is assembled with the concave mirror cover 2. The concave mirror cover 2 swings under external force, which drives the cover fixing plate 131 to swing relative to the main shaft 11. The swing of the cover fixing plate 131 is used to apply an axial thrust to the cover pressure guiding assembly 133. The cover pressure guiding assembly 133 is used to compress the cover compression spring 132 under force or to move under the reset force of the cover compression spring 132 to apply a locking force to the cover fixing plate 131.

[0026] In this way, when the concave mirror cover 2 is unfolded and put into use, the user applies an opening force to the concave mirror cover 2, causing the concave mirror cover 2 to swing relative to the rear cover 4. At this time, the cover fixing plate 131 swings synchronously, and the cover fixing plate 131 applies an axial force to the cover guiding pressure assembly 133 during the swing process, causing the cover guiding pressure assembly 133 to gradually compress the cover pressure spring 132, thereby gradually compressing the cover pressure spring 132. After unfolding to the correct position, the external force is removed, and the cover pressure spring 132 resets and applies spring pressure to the cover guiding pressure assembly 133 in the opposite direction. The cover guiding pressure assembly 133 applies a locking force to the cover fixing plate 131, thereby locking the cover fixing plate 131 and realizing the self-locking of the concave mirror cover 2. This allows the concave mirror cover 2 to be continuously and stably unfolded in a horizontal state, which is convenient for the use of the reading and writing station.

[0027] The cover pressure guiding assembly 133 includes a first cover guide ring 1331 and a second cover guide ring 1332. The first cover guide ring 1331 and the second cover guide ring 1332 are arranged correspondingly. The first cover guide ring 1331 and the cover compression spring 132 are assembled together. The cover fixing plate 131 is oscillating under force to drive the second cover guide ring 1332 to rotate relative to the first cover guide ring 1331. The rotation of the second cover guide ring 1332 is used to drive the first cover guide ring 1331 to move axially.

[0028] In this way, through the cooperation of the first cover guide ring 1331 and the second cover guide ring 1332, the cover compression spring 132 is compressed and reset, thereby realizing the unfolding and self-locking of the concave mirror cover 2.

[0029] The cover spring 132 can also be in a compressed state when the assembly is completed, so that the cover spring 132 has sufficient restoring force to lock the concave mirror cover 2.

[0030] Based on the weight of the concave mirror cover 2, select cover springs 132 of different specifications to ensure that the restoring force of the cover spring 132 is greater than the swinging force generated by the weight of the concave mirror cover 2, and avoid insufficient self-locking force.

[0031] The second cover guide ring 1332 has multiple cover ring platforms, which are arranged in a circular pattern with intervals between each other. The cover ring platforms are also arranged in a protruding manner. Under the action of the cover ring platforms, the first cover guide ring 1331 is driven to move axially.

[0032] The cover hinge module 13 includes at least one cover pad 134, which is elastically arranged in a direction away from the cover pressure guide assembly 133. The cover fixing plate 131 has a cover fixing surface, and the cover pad 134 is arranged to overlap and abut against the cover fixing surface. The cover pad 134 is used to buffer the cover fixing plate 131.

[0033] In this way, the cover pad 134 acts as a buffer for the cover plate 131 and also buffers the restoring force of the cover spring 132, thereby improving the service life of the hinge structure.

[0034] The cover hinge module 13 includes two cover pads 134, which are stacked together. Through the cooperation of the two cover pads 134, there is sufficient buffering force to ensure the buffering effect on the cover plate 131.

[0035] The cover plate 134 has a cover groove, which is arranged in a recessed manner. Under the action of the cover groove, the cover plate 134 is easy to deform and buffer, thereby improving the buffering effect of the cover plate 134.

[0036] The main shaft 11 has a split shaft plate, which is located between the rear fixed plate 12 and the cover pad 134, and the rear fixed plate 12 and the cover pad 134 clamp the split shaft plate; in this way, under the action of the split shaft plate, the separation between the cover hinge module 13 and the rear fixed plate 12 is achieved, so as to avoid the swing of the cover hinge module 13 from affecting the rear fixed plate 12.

[0037] Furthermore, the split-axis plate also effectively separates the cover hinge module 13 and the plate hinge module 14, ensuring that the cover hinge module 13 and the plate hinge module 14 do not affect each other, making the swing of the concave mirror cover 2 and the screen panel 3 relatively independent, and avoiding conflicts between the swing of the concave mirror cover 2 and the screen panel 3.

[0038] The cover plate 131 includes a main cover plate and a cover plate ring. The main cover plate and the cover plate ring are arranged in a butt-fitting assembly arrangement. The main shaft 11 is arranged in a movable assembly arrangement with the cover plate ring. The main cover plate is arranged in a stacked assembly arrangement with the concave mirror cover 2. The two ends of the main cover plate respectively form an upper edge plate and a lower edge plate. The upper edge plate and the lower edge plate are arranged in opposite directions. The cover plate ring is assembled with the lower edge plate in a butt-fitting assembly. The upper edge plate is used to embed and position the concave mirror cover 2.

[0039] Under the action of the upper edge plate, the assembly stability of the cover plate 131 and the concave mirror cover 2 is improved, ensuring that the concave mirror cover 2 synchronously drives the cover plate 131 to swing.

[0040] The plate hinge module 14 includes a plate fixing plate 141, a plate compression spring 142, and a plate pressure guiding assembly 143. The main shaft 11 passes through the plate fixing plate 141, the plate compression spring 142, and the plate pressure guiding assembly 143 simultaneously. One end of the plate compression spring 142 is fixed, and the other end of the plate compression spring 142 is assembled with the plate pressure guiding assembly 143. The plate fixing plate 141 is assembled with the screen panel 3. The screen panel 3 swings under external force, which drives the plate fixing plate 141 to swing relative to the main shaft 11. The swing of the plate fixing plate 141 is used to apply an axial thrust to the plate pressure guiding assembly 143. The plate pressure guiding assembly 143 is used to compress the plate compression spring 142 under force or to move under the reset force of the plate compression spring 142 to apply a locking force to the plate fixing plate 141.

[0041] In this way, when the screen panel 3 is unfolded for use, the user applies an opening force to the screen panel 3, causing the screen panel 3 to swing relative to the back cover 4. At this time, the plate fixing plate 141 swings synchronously, and the plate fixing plate 141 applies an axial force to the plate guiding pressure assembly 143 during the swing process, causing the plate guiding pressure assembly 143 to gradually compress the plate compression spring 142. As a result, the plate compression spring 142 is gradually compressed. After unfolding to the correct position, the external force is removed, and the plate compression spring 142 returns to its original position and applies spring pressure to the plate guiding pressure assembly 143 in the opposite direction. The plate guiding pressure assembly 143 applies a locking force to the plate fixing plate 141, thereby locking the plate fixing plate 141 and realizing the self-locking of the screen panel 3. This allows the screen panel 3 to be continuously and stably kept in an unfolded tilted state, which is convenient for the use of the reading and writing station.

[0042] The plate pressure guiding assembly 143 includes a first plate guide ring and a second plate guide ring, which are arranged correspondingly. The first plate guide ring and the plate compression spring 142 are assembled together. The plate fixing plate 141 is oscillating under force to drive the second plate guide ring to rotate relative to the first plate guide ring. The rotation of the second plate guide ring drives the first plate guide ring to move axially.

[0043] In this way, through the cooperation of the first guide ring and the second guide ring, the compression spring 142 is compressed and reset, thereby enabling the screen panel 3 to unfold and self-lock.

[0044] The plate spring 142 can also be in a compressed state when the assembly is completed, so that the plate spring 142 has sufficient restoring force to lock the screen panel 3.

[0045] Based on the weight of the screen panel 3, different specifications of plate compression springs 142 are selected to ensure that the restoring force of the plate compression springs 142 is greater than the swinging force generated by the weight of the screen panel 3, so as to avoid insufficient self-locking force.

[0046] like Figure 8 As shown, when the user swings the concave mirror cover 2 to a horizontal position, the concave mirror cover 2 drives the cover fixing plate 131 to swing, which in turn drives the second cover guide ring 1332 to rotate. In the horizontal position, the protruding area of ​​the second cover guide ring 1332 abuts against the protruding area of ​​the first cover guide ring 1331, thereby driving the first cover guide ring 1331 to move axially through the second cover guide ring 1332. The axial movement of the first cover guide ring 1331 will cause the cover compression spring 132 to be compressed. When the user removes the swinging force, the cover compression spring 132 applies a reverse elastic force to achieve self-locking of the concave mirror cover 2.

[0047] Example 1 of the pressure guiding assembly 133: The second cover guide ring 1332 and the cover fixing plate 131 are stacked and assembled to achieve the cooperation between the second cover guide ring 1332 and the cover fixing plate 131. Thus, the second cover guide ring 1332 is rotated by the swing of the cover fixing plate 131, thereby compressing the cover compression spring 132 and facilitating the subsequent application of self-locking force by the cover compression spring 132 in the opposite direction.

[0048] Example 2 of the pressure guiding assembly 133: The second cover guide ring 1332 includes a cover main ring and an outer edge 1333. The cover main ring and the outer edge 1333 are mated together, and the outer edge 1333 extends outward along the radial direction of the cover main ring. The outer edge 1333 is assembled with the cover fixing plate 131. The cover fixing plate 131 swings to drive the outer edge 1333 to swing. The swing of the outer edge 1333 drives the cover main ring to rotate. The rotation of the cover main ring drives the first cover guide ring 1331 to move axially.

[0049] In this way, the swing of the cover plate 131 causes the outer edge 1333 to swing, and the swing of the outer edge 1333 causes the main ring of the cover to rotate, thereby compressing the cover spring 132 and facilitating the subsequent application of a self-locking force by the cover spring 132 in the opposite direction.

[0050] Furthermore, the outer edge 1333 is embedded in the cover plate 131, which facilitates the cooperation between the outer edge 1333 and the cover plate 131, thereby facilitating the cooperation between the second cover guide ring 1332 and the cover plate 131, facilitating the application of a compressive force to the cover spring 132, and facilitating the subsequent application of a self-locking force by the cover spring 132 in the opposite direction.

[0051] Example 3 of the pressure guiding assembly 133: The cover hinge module 13 includes a cover locking plate, which has a cover locking block. The cover locking plate is located between the second cover guide ring 1332 and the cover fixing plate 131. The cover locking plate and the second cover guide ring 1332 are stacked and assembled, and the cover locking plate and the cover fixing plate 131 are arranged in a movable abutting arrangement. The cover fixing plate 131 has a cover fixing block, which is arranged in abutting or separate arrangement with the cover locking block. When the cover fixing block and the cover locking block are in abutting, the cover fixing plate 131 is rotated by force, which drives the cover locking plate to rotate. The rotation of the cover locking plate drives the second cover guide ring 1332 to rotate.

[0052] In this way, through the cooperation of the cover fixing block and the cover locking block, the second cover guide ring 1332 is rotated by the swing of the cover fixing plate 131, thereby applying a squeezing force to the cover compression spring 132 and facilitating the subsequent application of a self-locking force by the cover compression spring 132 in the opposite direction.

[0053] Example 1 of plate pressure guiding assembly 143: The second plate guide ring includes a main plate ring and a fixed plate segment 1431. The main plate ring and the fixed plate segment 1431 are mated together, and the fixed plate segment 1431 extends outward along the radial direction of the main plate ring. The fixed plate segment 1431 and the plate fixing plate 141 are assembled together. The plate fixing plate 141 swings to drive the fixed plate segment 1431 to swing. The swing of the fixed plate segment 1431 drives the main plate ring to rotate. The rotation of the main plate ring drives the first plate guide ring to move axially.

[0054] In this way, the swing of the plate fixing plate 141 causes the fixing plate segment 1431 to swing, and the swing of the fixing plate segment 1431 causes the main ring of the plate to rotate, thereby compressing the plate compression spring 142 and facilitating the subsequent application of self-locking force to the plate compression spring 142 in the opposite direction.

[0055] Furthermore, the fixed plate segment 1431 and the cover fixed plate 131 are embedded in each other, which facilitates the cooperation between the fixed plate segment 1431 and the cover fixed plate 131, thereby facilitating the cooperation between the second cover guide ring 1332 and the cover fixed plate 131, facilitating the application of a compressive force to the cover compression spring 132, and facilitating the subsequent application of a self-locking force by the cover compression spring 132 in the opposite direction.

[0056] The second plate guide ring has a fixed plate section 1431, which extends outward and is either embedded or separated from the plate fixing plate 141.

[0057] Example 2 of plate pressure guiding assembly 143: The second guide ring and the plate fixing plate 141 are stacked and assembled to achieve the cooperation between the second guide ring and the plate fixing plate 141. Thus, the second guide ring is rotated by the swing of the plate fixing plate 141, which compresses the plate compression spring 142 and facilitates the subsequent application of self-locking force to the plate compression spring 142 in the opposite direction.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

The cover locking plate is located between the second cover guide ring and the cover fixing plate, and the cover locking plate and the second cover guide ring are stacked together. The cover locking plate and the cover fixing plate are arranged in a movable abutting arrangement. The cover fixing plate has a cover fixing block, which is arranged in abutting or separate arrangement from the cover locking block. When the cover fixing block and the cover locking block are in abutting, the cover fixing plate is rotated by force, which causes the cover locking plate to rotate. The rotation of the cover locking plate causes the second cover guide ring to rotate.

6. The dual-control reader / writer hinge structure as described in any one of claims 2-5, characterized in that, The cover hinge module includes at least one cover pad, which is elastically arranged in a direction away from the cover pressure guiding assembly. The cover fixing plate has a cover fixing surface, and the cover pad and the cover fixing surface are arranged in an overlapping and abutting arrangement. The cover pad is used to buffer the cover fixing plate.

7. The dual-control reader / writer hinge structure as described in claim 6, characterized in that, The main shaft has a split plate, which is located between the rear fixing plate and the cover plate, and the rear fixing plate and the cover plate clamp the split plate.

8. The dual-control reader / writer hinge structure as described in any one of claims 2-5, characterized in that, The cover plate includes a main cover plate and a cover plate ring. The main cover plate and the cover plate ring are assembled together. The main shaft is movably assembled with the cover plate ring. The main cover plate is stacked with the concave mirror cover. The two ends of the main cover plate form an upper edge plate and a lower edge plate, which extend in opposite directions. The cover plate ring is assembled with the lower edge plate. The upper edge plate is used to embed and position the concave mirror cover.

9. The dual-control reader / writer hinge structure as described in any one of claims 1-5, characterized in that, The plate hinge module includes a plate fixing plate, a plate compression spring, and a plate pressure guiding assembly.

One end of the plate compression spring is fixed, and the other end of the plate compression spring is assembled with the plate pressure guiding assembly. The plate fixing plate is assembled with the screen panel. The screen panel swings under external force, which drives the plate fixing plate to swing relative to the main shaft. The swinging of the plate fixing plate is used to apply an axial thrust to the plate pressure guiding assembly. The plate pressure guiding assembly is used to compress the plate compression spring or move under the reset force of the plate compression spring to apply a locking force to the plate fixing plate.

10. The dual-control reader / writer hinge structure as described in claim 9, characterized in that, The plate pressure guiding assembly includes a first plate guide ring and a second plate guide ring, which are arranged correspondingly. The first plate guide ring is assembled with the plate compression spring in a mating arrangement. The plate fixing plate swings under force to drive the second plate guide ring to rotate relative to the first plate guide ring. The rotation of the second plate guide ring drives the first plate guide ring to move axially. The second plate guide ring has a fixing plate segment that extends outward and is either embedded or separated from the plate fixing plate.
