Description

Technical Field

[0001] This utility model relates to the field of reading pen technology, and in particular to a lens fixing structure for the photo-taking function of a reading pen. Background Technology

[0002] As a common learning aid, the reading pen, with the development of technology, not only has the function of reading aloud, but also integrates the function of taking pictures to look up words or solve problems. In order to realize the photo function, a camera module needs to be installed on the reading pen.

[0003] Existing reading pens use glue or screws to fix the camera module inside the pen body. This method makes it difficult to remove once installed. When the camera malfunctions or a higher-resolution lens is needed, users cannot replace it themselves and must repair or scrap the entire pen, resulting in high maintenance costs. Furthermore, the existing fixing structure lacks an effective anti-loosening mechanism. When the reading pen is dropped and impacted, the internal wiring connections of the camera may loosen, leading to poor contact and affecting the shooting effect. The existing camera is directly exposed on the pen body surface without necessary physical shielding. During carrying or storage, sharp objects can scratch the lens surface, seriously affecting image quality.

[0004] Therefore, this utility model proposes a lens fixing structure for the photo-taking function of the reading pen to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, such as the single fixing method of the lens assembly of the reading pen being difficult to disassemble and replace, easy loosening after long-term use leading to poor contact, and lack of effective physical shielding structure causing easy damage to the lens, this utility model aims to provide a reading pen camera lens fixing structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a lens fixing structure for the photo-taking function of a reading pen, including: a pen body, a pen tip fixedly connected to the front side of the pen body, a button fixedly connected to the side of the pen body, and a display screen fixedly connected to the bottom of the pen body. A sound hole is opened on the top of the pen body, a fixing mechanism is provided on the top of the pen body, a connecting post fixedly connected to the inner wall of the pen body, and a fixing block. The connecting post is located inside the fixing block, and a slot is opened inside the fixing block. The fixing mechanism also includes a hot-swappable lens.

[0007] The hot-swappable lens has a structure with a locking block fixedly connected to its outer wall, and an interface is provided at the bottom of the hot-swappable lens.

[0008] Furthermore, the card block, the connecting post, and the hot-swappable lens are slidably connected inside the card slot by the card block, the bottom of the hot-swappable lens abuts against the connecting post and is electrically connected, the outer wall of the fixing block is threaded with a limiting ring, the bottom of the limiting ring abuts against the top of the hot-swappable lens, and the limiting ring locks the hot-swappable lens inside the fixing block.

[0009] Preferably, the top of the pen body is also provided with a shielding mechanism, which includes an inclined groove opened on the top of the pen body and a trapezoidal baffle slidably connected inside the inclined groove. The trapezoidal baffle slides back and forth along the length of the inclined groove to shield or expose the hot-swappable lens.

[0010] Preferably, the shielding mechanism further includes a hollow column fixedly connected to the inner wall of the pen body. The hollow column is located below the inclined groove, and a spring is installed inside the hollow column. The bottom end of the spring is fixedly connected to the inner bottom wall of the hollow column.

[0011] Preferably, a conical block is fixedly connected to the top of the spring, the conical block is slidably connected to the inner wall of the hollow column, and the top of the conical block passes through the inner wall of the pen body under the elastic force of the spring and extends into the interior of the inclined groove.

[0012] Preferably, the bottom of the trapezoidal baffle abuts against the conical surface of the conical block. When the trapezoidal baffle slides along the inclined groove, the trapezoidal baffle squeezes the conical block, causing the conical block to compress the spring and slide downward along the hollow column.

[0013] Preferably, after the trapezoidal baffle slides past the conical block, the conical block resets under the rebound force of the spring and blocks the reverse movement of the trapezoidal baffle, thereby limiting the position of the trapezoidal baffle.

[0014] Preferably, the longitudinal section of the trapezoidal baffle is trapezoidal, the cross-sectional shape of the inclined groove is adapted to the shape of the trapezoidal baffle, and the trapezoidal baffle is engaged in the inclined groove and cannot be detached from the pen body.

[0015] Preferably, the inner diameter of the limiting ring is smaller than the outer diameter of the top of the hot-swappable lens, the inner wall of the limiting ring is provided with an internal thread, and the outer wall of the fixing block is provided with an external thread that matches the internal thread.

[0016] Preferably, the connecting post is vertically fixed at the center of the fixing block, the bottom of the hot-swappable lens is provided with an interface that matches the connecting post, and the locking block protrudes outward along the radial direction of the hot-swappable lens.

[0017] Preferably, the sound hole is located at the center of the top of the pen body, the fixing mechanism is located on the side of the sound hole, and the display screen is embedded in the lower half of the pen body surface.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of the existing technology of single fixing method of reading pen lens assembly, difficulty in modular replacement, and easy loosening and poor contact after long-term use by setting a fixing block with connecting post and slot inside the pen body, together with hot-swappable lens with locking block on the outer wall and threaded limit ring. It achieves the effect of realizing quick hot-swappable installation of lens, ensuring stable and reliable electrical connection, and effectively preventing lens from accidentally slipping out.

[0019] 2. This utility model solves the problems of existing reading pen lenses lacking physical protection devices, being easily scratched or damaged by impact, and having protective covers easily shifted due to accidental touch by setting a sliding trapezoidal baffle on the top of the pen body and cooperating with an elastic positioning component composed of springs and conical blocks. It achieves the effect of effectively shielding and protecting the lens when not in use, preventing dust from entering, and automatically locking the position of the protective cover, thus improving ease of use and product durability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 6 This utility model provides a lens fixing structure for the photo-taking function of a reading pen, which aims to solve the problems of unstable lens fixing structure, difficulty in hot-swapping replacement, and lack of effective physical shielding protection when not in use, thus making it susceptible to damage from external impacts.

[0024] Please refer to Figure 1 and Figure 2 The camera lens fixing structure of the reading pen includes a pen body 1, a pen tip 2 fixedly connected to the front side of the pen body 1, a button 4 fixedly connected to one side of the pen body 1, a display screen 5 embedded and fixedly connected to the lower half of the surface of the pen body 1, a sound hole 3 opened at the center of the top of the pen body 1, and a fixing mechanism 6 provided at the top of the pen body 1, located next to the sound hole 3. The fixing mechanism 6 includes a connecting post 601 vertically fixedly connected to the inner wall of the pen body 1, and a fixing block 602 fixedly connected to the inner wall of the pen body 1. The connecting post 601 is located at the center of the fixing block 602, and the fixing block 602 has a slot 603 inside. The fixing mechanism 6 also includes a hot-swappable lens 604, the outer wall of which is fixedly connected to a radially... A protruding locking block 605 slides along the axial direction of the fixing block 602 inside the slot 603. The bottom of the hot-swappable lens 604 has an interface that abuts against the connecting post 601 and achieves electrical connection. The outer wall of the fixing block 602 has an external thread, and a limiting ring 606 is connected to the thread on the outer wall of the fixing block 602. The inner wall of the limiting ring 606 has an internal thread that matches the external thread. The bottom of the limiting ring 606 abuts against the top of the hot-swappable lens 604. The inner diameter of the limiting ring 606 is smaller than the outer diameter of the top of the hot-swappable lens 604. By tightening the limiting ring 606, the hot-swappable lens 604 is locked inside the fixing block 602. The model of the hot-swappable lens 604 is JQ-7251-17-v1.0.

[0025] Please refer to Figure 1 , Figure 5 and Figure 6The shielding mechanism 7 includes a sloping groove 701 formed at the top of the pen body 1, located above the fixing mechanism 6. The shielding mechanism 7 also includes a trapezoidal baffle 702 slidably connected inside the sloping groove 701. The longitudinal section of the trapezoidal baffle 702 is trapezoidal, and the cross-sectional shape of the sloping groove 701 matches the shape of the trapezoidal baffle 702. The trapezoidal baffle 702 is engaged within the sloping groove 701 and cannot detach from the pen body 1. The trapezoidal baffle 702 can slide back and forth along the length of the sloping groove 701 to shield or expose the hot-swappable lens 604. The shielding mechanism 7 also includes a hollow column 703 fixedly connected to the inner wall of the pen body 1, located below the sloping groove 701. A spring is fixedly connected inside the hollow column 703. 704, the bottom end of spring 704 is fixedly connected to the inner bottom wall of hollow column 703, and the top end of spring 704 is fixedly connected to conical block 705. Conical block 705 is slidably connected to the inner wall of hollow column 703. Under the elastic force of spring 704, the top of conical block 705 passes through the inner wall of pen body 1 and extends into the interior of inclined groove 701. The bottom of trapezoidal baffle 702 abuts against the conical surface of conical block 705. When trapezoidal baffle 702 slides along inclined groove 701, trapezoidal baffle 702 squeezes conical block 705, causing conical block 705 to compress spring 704 and slide downward along hollow column 703, ensuring the positioning feel of trapezoidal baffle 702 during sliding, as well as its position holding ability in closed or open states.

[0026] In a preferred embodiment, in order to achieve stable lens fixation and electrical connection, the fixing mechanism 6 includes a sliding engagement between the hot-swappable lens 604 and the slot 603 of the fixing block 602, and an electrical contact between the bottom of the hot-swappable lens 604 and the connecting post 601. The hot-swappable lens 604 is firmly locked in the fixing block 602 by the threaded connection between the limiting ring 606 and the outer wall of the fixing block 602. The inner diameter of the limiting ring 606 is smaller than the outer diameter of the top of the hot-swappable lens 604, thereby preventing the hot-swappable lens 604 from accidentally coming out.

[0027] In another preferred embodiment, in order to achieve effective lens blocking and protection, the blocking mechanism 7 includes a sliding engagement between a trapezoidal baffle 702 and a sloping groove 701, and an abutting engagement between the trapezoidal baffle 702 and a conical block 705. When the trapezoidal baffle 702 slides past the conical block 705, the trapezoidal baffle 702 presses the conical block 705 downward and compresses the spring 704. After the trapezoidal baffle 702 completely passes over the conical block 705, the conical block 705 resets under the action of the spring 704's rebound force, thereby blocking the reverse movement of the trapezoidal baffle 702 and achieving the blocking or exposure positioning of the hot-swappable lens 604.

[0028] As another preferred embodiment, in order to adapt to the ergonomic design of the reading pen, the display screen 5 is fixedly connected to the lower half of the pen body 1, so that the user can intuitively view the information on the display screen 5 when holding the pen body 1. The sound hole 3 is located at the center of the top of the pen body 1, and the fixing mechanism 6 is set on the side of the sound hole 3. This makes reasonable use of the space at the top of the pen body 1, ensuring the normal transmission of sound and facilitating the installation and use of the hot-swappable lens 604.

[0029] Working principle: When installing the lens using the lens fixing structure of the reading pen's photo function, the operator aligns the locking block 605 on the hot-swappable lens 604 with the locking groove 603 inside the fixing block 602 and inserts it along the locking groove 603. During the insertion process, the bottom of the hot-swappable lens 604 aligns with the connecting post 601 to complete the electrical connection. Subsequently, the operator puts the limiting ring 606 on the outside of the fixing block 602 and tightens it with threads. Since the inner diameter of the limiting ring 606 is smaller than the outer diameter of the top of the hot-swappable lens 604, the limiting ring 606 locks the hot-swappable lens 604 inside the fixing block 602, preventing the hot-swappable lens 604 from accidentally slipping out and ensuring the stability of the connection.

[0030] When the camera function is not in use and protection of the hot-swappable lens 604 is required, the operator slides the trapezoidal baffle 702 located in the inclined groove 701 backward. The bottom of the trapezoidal baffle 702 contacts and presses against the inclined surface of the conical block 705. The conical block 705 is pressed and slides downward along the hollow column 703, pressing against the spring 704. Then, the trapezoidal baffle 702 passes over the conical block 705 and blocks the hot-swappable lens 604. At this time, the conical block 705 is no longer pressed by the trapezoidal baffle 702. Under the action of the spring 704, the conical block 705 returns to its original position, thereby limiting the position of the trapezoidal baffle 702 and preventing it from sliding freely, thus avoiding damage to the hot-swappable lens 604 from external impact.

[0031] When the camera function is needed, the operator slides the trapezoidal baffle 702 forward. The trapezoidal baffle 702 then presses the conical block 705, causing the conical block 705 to sink. After the trapezoidal baffle 702 passes the conical block 705, the hot-swappable lens 604 is exposed. Under the action of the spring 704, the conical block 705 returns to its original position and blocks the trapezoidal baffle 702, thus realizing the rapid opening and positioning of the hot-swappable lens 604.
