Technical Field
[0001] This utility model relates to the field of office meeting equipment technology, and in particular to a video conferencing terminal with a built-in wireless projection module. Background Technology
[0002] With the popularization of remote collaborative work mode, video conferencing terminals have become an indispensable intelligent device in modern enterprise conference rooms. In order to ensure a good video acquisition field of view, traditional desktop video conferencing terminals usually adopt a vertical structure, that is, the host integrating the camera and processing module is mounted at a certain height by a base and a fixed support rod, and a simple damping hinge is used for manual angle fine adjustment. However, this traditional structural design has obvious problems with space utilization and form adaptability in practical applications. Since most existing video conferencing terminals are fixed in shape or only support limited manual adjustment, when the equipment is idle after the meeting, it still maintains a vertical posture, occupying valuable conference table space. Moreover, the precision lens components exposed to the outside are easily damaged by accidental bumps or dust. More importantly, this rigid structure that cannot change its shape significantly makes the equipment bulky and irregularly shaped when it needs to be moved or stored, making it difficult to flatten and pack into boxes, resulting in increased transportation costs and inconvenience in carrying. Existing technical solutions lack a mechanical structure that can automatically switch the equipment between vertical working state and horizontal storage state, satisfying both multi-angle shooting and hidden storage.
[0003] Therefore, this utility model proposes a video conferencing terminal with a built-in wireless screen projection module to address the shortcomings of the prior art. Utility Model Content
[0004] In view of the problems of traditional desktop video conferencing terminals in the prior art, such as large size and fixed shape, which result in large space occupation and inconvenience of moving and storing when not in use, and the fact that the internal wireless module adopts a fully enclosed fixed structure, which leads to cumbersome disassembly and maintenance, high repair costs and low efficiency when malfunctions, this utility model aims to provide a video conferencing terminal with an improved structure that can realize automated form switching and quick disassembly and maintenance with a built-in wireless projection module.
[0005] This utility model provides a video conferencing terminal with a built-in wireless screen projection module, including: a base box, and a conference box rotatably connected to the top of the base box.
[0006] The base box contains an angle adjustment mechanism that converts linear drive into rotary output. The angle adjustment mechanism includes an electric push rod fixedly mounted at the bottom of the base box, with a gear rod coaxially connected to the output end of the electric push rod.
[0007] Furthermore, a half-gear is rotatably mounted inside the base box, meshing with the rack and pinion. A connecting plate is fixedly connected to the side of the half-gear, and the end of the connecting plate away from the half-gear is fixedly connected to the bottom of the conference box. The electric push rod drives the rack and pinion to reciprocate horizontally, and through gear and rack transmission, drives the half-gear and the connecting plate to rotate, thereby causing the conference box to flip between a vertical and a horizontal state.
[0008] Preferably, the angle adjustment mechanism further includes a connecting rod and a fixing assembly. The fixing assembly includes a fixing plate, which is bolted to the housing of the electric push rod. The connecting rod is fixedly connected to the fixing plate, and the half-gear is rotatably sleeved on the outer periphery of the connecting rod. This configuration utilizes the electric push rod itself as a mounting base, simplifying the internal support structure.
[0009] Preferably, the video conferencing terminal further includes a top cover that fits over the top opening of the conference box. A positioning mechanism is provided at the connection between the conference box and the top cover. The positioning mechanism includes a housing fixedly installed on the inner wall of the conference box and a locking rod fixedly installed on the bottom surface of the top cover. A movable block is rotatably installed inside the housing. One end of the movable block has a locking block for engaging the locking rod, and the other end of the movable block extends to the outside of the housing. This structure enables tool-free quick assembly and disassembly of the top cover.
[0010] Preferably, a fixing bolt is fixedly installed on the inner wall of the outer casing, and the middle part of the movable block is rotatably sleeved on the outer periphery of the fixing bolt, so that the movable block forms a lever structure. Through the lever principle, the user only needs to apply a small amount of external pressure to unlock the internal latch.
[0011] Preferably, the positioning mechanism further includes a second movable column and a second spring disposed at the bottom of the outer casing. One end of the second spring is fixedly connected to the inner bottom wall of the outer casing, and the other end of the second spring is fixedly connected to the second movable column. The end of the second movable column away from the second spring abuts against the bottom surface of the end of the movable block located inside the outer casing. The second spring is in a compressed state, providing the movable block with elastic force to reset the latch and lock the locking rod, ensuring that the latch is always locked when no one is operating it.
[0012] Preferably, the positioning mechanism further includes a movable column and a spring disposed at the bottom of the housing. One end of the spring is fixedly connected to the inner bottom wall of the housing, and the other end of the spring is fixedly connected to the movable column. The end of the movable column away from the spring extends vertically and abuts against the bottom surface of the locking rod. The spring applies an upward clamping force to the locking rod, forming a double fixation with the locking block and eliminating assembly gaps.
[0013] Preferably, the locking rod has an L-shaped structure, and the bottom horizontal section of the locking rod is adapted to the slot of the locking block to ensure the stability of the locking.
[0014] Preferably, the top surface of the base box has a mounting groove for storing the conference box. When the conference box is flipped to a horizontal position, the conference box is completely stored inside the mounting groove, realizing flat storage of the equipment, which is convenient for transportation and stacking.
[0015] Preferably, a wireless projection module is installed inside the conference box, and the wireless projection module is located below the top cover. This, combined with the quick-release top cover structure, allows maintenance personnel to quickly access and maintain the wireless projection module.
[0016] This utility model has the following beneficial effects: 1. This utility model incorporates an angle adjustment mechanism inside the base box. An electric push rod drives a rack to perform linear motion, which, in conjunction with a half-gear and connecting plate, converts the linear motion into rotational motion. This allows the conference box to freely switch between a vertical usage state and a horizontal storage state. This solves the problems of existing video conferencing terminals being bulky, having a single camera angle, and being difficult to move and store. It achieves the technical effects of completely storing the device in the mounting slot when not in use, significantly reducing the device's size, facilitating transport, and protecting the camera.
[0017] 2. This utility model, by setting a positioning mechanism at the connection between the conference box and the top cover, and utilizing the lever principle to design a movable block that engages with a locking block and a latching rod, enables tool-free quick assembly and disassembly of the top cover. This solves the problem in existing technologies where the wireless projection module is sealed inside the device, requiring disassembly of the entire unit for repairs, resulting in high maintenance costs and time consumption. It achieves the technical effect of quickly opening the top cover to replace or repair internal components, significantly reducing maintenance difficulty and downtime.
[0018] 3. This utility model incorporates a double spring and moving column structure in the positioning mechanism. The first spring pushes the moving column upward to press against the locking rod, while the second spring pushes the moving column to reset the movable block, causing the locking block to press downward against the locking rod. This solves the problem of looseness or gaps after the top cover is installed, achieving a double fixation through bidirectional clamping force, ensuring a stable, tight, and wobbly connection of the top cover.

[0021] Example: Reference Figures 1 to 4 This utility model provides a video conferencing terminal with a built-in wireless projection module, which aims to solve the structural defects of existing video conferencing terminals, such as large size that is not easy to store, single camera shooting angle that cannot be adapted to different meeting scenarios, and the structural defects of the internally packaged wireless module that make disassembly and maintenance difficult and increase maintenance costs due to the fixing method of the top cover 5 when it malfunctions.
[0022] like Figure 1 and Figure 4As shown, the video conferencing terminal with a built-in wireless projection module includes a base box 4 and a conference box 1 rotatably connected above the base box 4. The base box 4 serves as the support and mounting base for the entire device, accommodating the driving components and providing a stable support surface. The conference box 1 serves as the carrier for functional components, installing core electronic components such as cameras and wireless projection modules. The conference box 1 can be rotated relative to the base box 4 to change its usage posture.
[0023] The top surface of the base box 4 is provided with a mounting groove. The shape and size of the mounting groove are adapted to the conference box 1. When the conference box 1 is idle or in storage, it can be flipped to a horizontal position and completely stored inside the mounting groove, thereby greatly reducing the overall volume occupied by the equipment and facilitating the handling and storage of the equipment. The base box 4 is provided with an angle adjustment mechanism 2. The angle adjustment mechanism 2 is used to provide power and change the motion mode to drive the conference box 1 to smoothly switch between the vertical use state and the horizontal storage state.
[0024] like Figure 2 and Figure 4 As shown, the angle adjustment mechanism 2 includes an electric push rod 21 fixedly installed at the bottom of the base box 4. The electric push rod 21 serves as a power source for outputting linear reciprocating motion. A rack 22 is coaxially fixedly connected to the output end of the electric push rod 21. The rack 22 reciprocates in the horizontal direction following the extension and retraction of the electric push rod 21. A half gear 23 is rotatably installed inside the base box 4. The tooth surface of the half gear 23 is always meshed with the rack 22. Through the transmission of the gear and rack, the linear motion of the rack 22 is converted into the rotational motion of the half gear 23.
[0025] A connecting plate 25 is fixedly connected to the side of the half gear 23. The end of the connecting plate 25 away from the half gear 23 extends out of the bottom box 4 and is fixedly connected to the bottom of the conference box 1. The connecting plate 25 plays the role of transmitting torque and connecting support. When the electric push rod 21 drives the rack 22 to move, the rack 22 drives the half gear 23 to rotate, and then drives the conference box 1 to rotate around the rotation center of the half gear 23 through the connecting plate 25, so as to realize the automatic adjustment of the camera angle to adapt to the meeting scene where multiple people sit around or to complete the storage action.
[0026] Reference Figure 2 and Figure 4 The fixing component 26 includes two parallel fixing plates 261, which are fixedly mounted on the outer surface of the electric push rod 21 by bolts 262. The electric push rod 21 itself is used as the mounting base, which simplifies the internal structural layout of the base box 4. The two ends of the connecting rod 24 are fixedly connected to the two fixing plates 261 respectively, so that the connecting rod 24 spans across the electric push rod 21 and remains stationary, providing a stable rotation fulcrum for the half gear 23.
[0027] The half gear 23 is rotatably sleeved on the outer circumference of the connecting rod 24. Its inner hole and the outer diameter of the connecting rod 24 are fitted with clearance to ensure that the half gear 23 can rotate smoothly around the connecting rod 24. The connecting rod 24 not only restricts the displacement of the half gear 23 in the horizontal and vertical directions, but also bears the radial force generated when the gear meshes, ensuring the smoothness and reliability of the transmission process.
[0028] In this embodiment, the video conferencing terminal also includes a top cover 5, which covers the top opening of the conference box 1 to seal the internal space of the conference box 1 and protect the internal precision electronic components such as the wireless projection module. In order to solve the problem of difficult disassembly and maintenance caused by the fixing method of the top cover 5 in the prior art, multiple positioning mechanisms 3 are provided at the connection between the conference box 1 and the top cover 5.
[0029] The positioning mechanism 3 includes a housing 31 fixedly installed on the inner wall of the conference box 1, and a locking rod 35 fixedly installed on the bottom surface of the top cover 5. The housing 31 serves as the main support of the positioning mechanism 3 and is used to install the internal movable components. The locking rod 35 serves as the locking component and is disassembled or installed together with the top cover 5. The locking rod 35 has an L-shaped structure and a horizontal section at its bottom for locking. The structure facilitates a reliable mechanical interlock with the locking components.
[0030] A movable block 32 is rotatably installed inside the outer casing 31. The movable block 32 uses the lever principle to lock and release the locking rod 35. A fixing bolt 34 is fixedly installed on the inner wall of the outer casing 31. The middle part of the movable block 32 is rotatably sleeved on the outer periphery of the fixing bolt 34, so that the movable block 32 forms a lever structure with the fixing bolt 34 as the fulcrum. One end of the movable block 32 is provided with a locking block 33. The shape of the locking block 33 is adapted to the horizontal section at the bottom of the locking rod 35, and is used to hook and lock the locking rod 35. The other end of the movable block 32 extends to the outside of the outer casing 31 as a manual operation end, allowing the user to apply pressure to release the locking state.
[0031] In a preferred embodiment, to ensure that the movable block 32 can automatically reset and always maintain the locking state of the locking rod 35, the positioning mechanism 3 also includes a second movable column 38 and a second spring 39 disposed on the bottom surface inside the housing 31. One end of the second spring 39 is fixedly connected to the inner bottom wall of the housing 31, and the other end is fixedly connected to the bottom surface of the second movable column 38. The second movable column 38 slides through the limiting structure inside the housing 31. The end of the second movable column 38 away from the second spring 39 extends upward and abuts against the bottom surface of the end of the movable block 32 located inside the housing 31. Under normal conditions, the second spring 39 is in a compressed energy storage state and uses its own elastic restoring force to continuously push the second movable column 38 upward, so that the second movable column 38 applies an upward pushing force to the inner end of the movable block 32, forcing the end of the movable block 32 with the locking block 33 to press downward, thereby preventing the locking block 33 from accidentally falling off.
[0032] As another preferred embodiment, in order to eliminate the gap shaking after the top cover 5 is installed and to achieve a double fixing effect, the positioning mechanism 3 also includes a movable column 36 and a spring 37 disposed on the bottom surface inside the outer shell 31. One end of the spring 37 is fixedly connected to the inner bottom wall of the outer shell 31, and the other end is fixedly connected to the bottom surface of the movable column 36. The position of the movable column 36 corresponds to the position where the locking rod 35 is inserted into the outer shell 31. The end of the movable column 36 away from the spring 37 slides vertically through and extends to the top opening of the outer shell 31. When the locking rod 35 is inserted into the outer shell 31, the bottom surface of the locking rod 35 presses against the top of the movable column 36 and compresses the spring 37. The reverse elastic force generated by the spring 37 pushes the movable column 36 upward to tightly press against the locking rod 35, forming a clamping force state with the downward pressing block 33 above, ensuring that the top cover 5 is closed tightly.
[0033] As another preferred embodiment, in order to achieve flat storage of the device, the top surface of the bottom box 4 is provided with a mounting groove for storing the conference box 1. The depth and outline dimensions of the mounting groove match the conference box 1. When the device needs to be stored, the angle adjustment mechanism 2 drives the conference box 1 to flip to a horizontal state. At this time, the conference box 1 is completely sunk into and stored inside the mounting groove, making the top surface of the entire device tend to be flat, which is convenient for stacking and storage or packing and transportation.
[0034] As another preferred embodiment, in order to facilitate the maintenance of core components, a wireless projection module is installed inside the conference box 1. The wireless projection module is located in the area directly below the top cover 5. After the top cover 5 is quickly removed by the positioning mechanism 3, maintenance personnel can directly access and replace the wireless projection module without disassembling other shell parts of the conference box 1.
[0035] The working principle is as follows: When a video conference is needed, the control system sends a command to the angle adjustment mechanism 2 inside the base box 4. The electric push rod 21, which is fixedly installed at the bottom of the base box 4, starts working, and its output end drives the rack 22 to extend linearly in the horizontal direction. Since the rack 22 and the half gear 23 are always in a meshed state, the horizontal displacement of the rack 22 drives the half gear 23 to rotate around the connecting rod 24.
[0036] As the half gear 23 rotates, the connecting plate 25 fixed to its side swings, which in turn causes the conference box 1 connected to the other end of the connecting plate 25 to flip upward until the conference box 1 reaches the vertical use state. At this time, the camera can perform normal video acquisition. When the meeting ends and needs to be stored, the electric push rod 21 retracts in the opposite direction and drives the conference box 1 to flip downward through the same transmission path until the conference box 1 is completely flat and put into the mounting slot at the top of the bottom box 4, realizing the flat storage of the equipment.
[0037] When the wireless projection module inside the device malfunctions and needs repair, or when the internal components need cleaning, the operator needs to open the top cover 5. At this time, the operator presses down on the end of the movable block 32 that extends to the outside of the outer shell 31. The movable block 32 rotates around the fixing bolt 34. According to the lever principle, the end of the movable block 32 located inside the outer shell 31 tilts upward, causing the locking block 33, which was originally hooked on the locking rod 35, to disengage from the horizontal section of the locking rod 35.
[0038] At the same time, the spring 37, which is under compression, releases its elasticity, pushing the moving column 36 upward to lift the locking rod 35, and the top cover 5 pops up to complete the unlocking and separation. The operator can then remove the top cover 5 for maintenance.
[0039] When the top cover 5 needs to be replaced after maintenance, align the locking lever 35 at the bottom of the top cover 5 with the opening of the insert housing 31, and press the top cover 5 down firmly. The bottom surface of the locking lever 35 will press the moving column 36 downward and compress the spring 37. At the same time, press one end of the movable block 32 again to make the locking block 33 pop up. After the locking lever 35 is fully in place, release the pressure on the movable block 32.
[0040] At this time, the spring 39 at the bottom of the outer casing 31 releases its restoring force, pushing the moving column 38 upward. The moving column 38 pushes the inner end of the movable block 32 upward to reset, causing the locking block 33 to fall down again and hook onto the horizontal section of the locking rod 35. Under the combined action of the downward hooking force of the locking block 33 and the upward pushing force of the moving column 36, the locking rod 35 is firmly clamped and fixed, thereby achieving a firm connection between the top cover 5 and the conference box 1.
