Description

Technical Field

[0001] This utility model relates to the technical field of anti-glare high-precision display panels for multi-functional instruments, specifically an anti-glare high-precision display panel for multi-functional instruments. Background Technology

[0002] A multi-functional instrument is an intelligent instrument that integrates multiple functions. It is widely used in industrial automation, power systems, energy management, transportation and other fields. It can measure a variety of electrical parameters such as voltage, current, active power, reactive power, power factor, frequency and even power quality parameters such as harmonic content and three-phase imbalance.

[0003] Currently, Chinese patent CN220054027U discloses a multi-functional instrument with high waterproof performance, including an upper cover and a lower cover. The surface of the upper cover has buttons and a display panel, and the bottom of the lower cover extends outward to provide a mounting base. A handrail hoop seat is connected to the mounting base. The handrail hoop seat and the mounting base have matching mounting holes. A hoop is connected to the handrail hoop seat. The surface of the display panel has a waterproof cover. The buttons are located inside the waterproof mounting base. First, by shortening the overall length of the mounting base and the handrail hoop seat, the gear shift lever can be closer to the handrail, making it easier to hold. At the same time, by setting a waterproof cover on the surface of the display panel, and by using a mounting protrusion to connect with a circular groove, compared with traditional technology, the waterproof cover of this design will not have relative movement with the circular groove, avoiding gaps between the waterproof cover and the sealing ring under frequent movement, thus ensuring waterproof performance.

[0004] The aforementioned high-waterproof multi-functional instrument has some problems in actual use. When used outdoors, it may be exposed to strong light, which may cause mirror reflection, forming light spots or reflections. Especially when using a high-precision display panel, light spots or reflections may obscure part of the display content, making it difficult to identify information. At the same time, strong light may directly stimulate the human eye and cause visual discomfort, thus reducing the dizziness caused by strong light. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision, anti-glare display panel for a multifunctional instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-precision anti-glare display panel for a multi-functional instrument includes a high-precision display panel installed in a mounting groove in the instrument case. The outer circular surface of the high-precision display panel is fitted with a light-shielding ring for blocking light. A protective sheet is connected to the upper opening of the light-shielding ring by a snap-fit ​​component. Pushing components for pushing the light-shielding ring upward are provided on the inner walls of both sides of the mounting groove. A locking component is provided at the bottom of the instrument case for locking the pushing components to prevent the light-shielding ring from sliding out of the mounting groove.

[0007] As a preferred technical solution, the pusher includes sliding grooves respectively opened on both sides of the mounting groove. The inner cavity of each set of sliding grooves is provided with a push spring. The top of each set of push springs is provided with a sliding seat. The two sets of sliding seats are slidably connected to the inner cavity of the corresponding side sliding groove. The bottom of both sides of the light-shielding ring are connected to the corresponding side sliding seat through a connector.

[0008] As a preferred technical solution, the connector includes through holes respectively opened on the lower inner wall of both sides of the light-shielding ring, and fixing bolts are respectively inserted into the inner cavity of the two sets of through holes. The screws of the two sets of fixing bolts pass through the corresponding side through holes and are threaded to the surface of the corresponding side sliding seat.

[0009] As a preferred technical solution, the locking component includes inserts fixedly connected to the bottom of each set of sliding seats. The bottom of the sliding groove has slots for the inserts to be inserted. Inside the watch case, and on the inner side of each set of slots, are horizontally arranged circular grooves. Sliding discs are slidably connected to the inner cavities of both sets of circular grooves. Return springs are connected to opposite ends of the two sets of sliding discs. Positioning rods are fixedly connected to opposite ends of the two sets of sliding discs. The opposite ends of the two sets of positioning rods are slidably inserted into... In the inner cavity of the corresponding side slot, the bottom of the two sets of inserts on opposite sides are provided with insertion holes. The lower corners of the opposite ends of the two sets of inserts are set at a chamfer. When the insert enters the slot downwards, the positioning rod needs to be temporarily retracted by squeezing it at the chamfer until the insertion hole is aligned with the end of the positioning rod. Under the push of the corresponding side reset spring, the two sets of positioning rods are inserted into the inner cavity of the corresponding side insertion hole. The bottom of the watch case is provided with a sliding disc that moves to the opposite side to compress the spring and make the positioning rod slide out of the slot.

[0010] As a preferred technical solution, the actuating component includes a guide hole formed at the bottom of the watch case and located below each set of circular grooves. The two sets of guide holes are respectively connected to the corresponding side circular grooves. The bottom of the two sets of sliding discs is respectively fixedly connected to a connecting piece. The bottom of the two sets of connecting pieces passes downward through the corresponding side guide hole and is fixedly connected to a lever. The two sets of levers are respectively slidably connected to the bottom surface of the watch case.

[0011] As a preferred technical solution, the snap-fit ​​component includes a slot formed on the top surface of the light-shielding ring, and a snap ring is snapped into the inner cavity of the slot, the snap ring being fixedly connected to the bottom surface of the protective sheet.

[0012] As a preferred technical solution, the outer circular surface of the light-shielding ring is fixedly connected with several sets of limiting protrusions, and the inner wall of the mounting groove is provided with limiting grooves at corresponding positions of each set of limiting protrusions to allow the limiting protrusions to slide, so as to prevent the light-shielding ring from rotating circumferentially within the mounting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the design of a light-shielding ring, can specifically block direct strong light, effectively reducing specular reflection, light spots, and reflections on the display panel surface caused by strong light, ensuring that the displayed content is clearly legible, solving the problem of difficult information recognition, and preventing strong light from directly stimulating the human eye and causing visual discomfort, thereby reducing dizziness caused by strong light. The snap-fit ​​structure between the protective sheet and the light-shielding ring can protect the display panel without affecting the light-shielding function of the light-shielding ring. At the same time, the push and locking parts work together to allow the light-shielding ring to extend and retract flexibly. It can quickly activate the light-shielding function in strong light environments, and does not take up extra space when retracted in non-strong light environments, thus combining practicality and convenience.

[0014] This invention, through the arrangement of a sliding groove, a pushing spring, and a sliding seat, can quickly release elastic potential energy to push the light-shielding ring out when strong light causes reflection. It can form a light-shielding barrier in time without complicated operation, quickly improving the viewing conditions of the display panel. Furthermore, the sliding seat slides smoothly along the sliding groove to ensure that the position of the light-shielding ring is stable after it pops out, and the light-shielding range is accurate. It avoids unstable light-shielding effect due to shaking, and further ensures the reliability of information recognition under strong light.

[0015] This invention, through the cooperation of a strip, slot, positioning rod, and return spring, can stably lock the light-shielding ring in the mounting groove when it is stored, preventing the light-shielding ring from slipping out due to accidental contact, thus improving structural safety. Furthermore, the chamfered design at the bottom of the strip allows it to automatically squeeze the positioning rod and retract it when the light-shielding ring is pressed for storage, eliminating the need for manual operation of the locking mechanism and simplifying the storage process. In addition, the return spring ensures that the positioning rod automatically pops out and inserts into the socket after alignment, achieving automatic locking. The locking process is reliable and efficient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment provides a high-precision anti-glare display panel for a multi-functional instrument, including a high-precision display panel 102 installed in a mounting groove 104 of a casing 100. A light-shielding ring 200 is fitted onto the outer circular surface of the high-precision display panel 102. A protective sheet 201 is connected to the upper opening of the light-shielding ring 200 via a snap-fit ​​component. Pushing components for pushing the light-shielding ring 200 upwards are provided on the inner walls of both sides of the mounting groove 104. A locking component is provided at the bottom of the casing 100 to lock the pushing components and prevent the light-shielding ring 200 from sliding out of the mounting groove 104. Through the setting of the light-shielding ring 200, direct strong light can be effectively blocked. The system effectively reduces specular reflections, light spots, and reflections on the surface of the high-precision display panel 102 caused by strong light, ensuring that the displayed content is clear and legible, solving the problem of information recognition difficulties. Furthermore, it avoids direct stimulation of the human eye by strong light, thus reducing the dizziness caused by strong light. The snap-fit ​​structure between the protective sheet 201 and the light-shielding ring 200 can protect the high-precision display panel 102 without affecting the light-shielding function of the light-shielding ring 200. At the same time, the pusher and locking parts work together to enable the light-shielding ring 200 to extend and retract flexibly. The light-shielding function can be quickly activated in strong light environments, and it does not take up extra space when retracted in non-strong light conditions, thus combining practicality and convenience.

[0020] The high-precision display panel 102 is a consensus among those skilled in the art, including but not limited to LCD modules that support 16-bit true color display and have a resolution of ≥300PPI, which will not be elaborated on here.

[0021] The pusher includes sliding grooves 301 respectively opened on both sides of the mounting groove 104. The inner cavity of each sliding groove 301 is provided with a push spring 302. The top of each push spring 302 is provided with a sliding seat 300. The two sliding seats 300 are slidably connected to the inner cavity of the corresponding sliding groove 301. The bottom of both sides of the light-shielding ring 200 are connected to the corresponding sliding seat 300 through connectors. With the arrangement of sliding grooves 301, push springs 302 and sliding seats 300, when strong light causes reflection, the elastic potential energy can be quickly released to push the light-shielding ring 200 to pop out. The light-shielding barrier can be formed in time without complicated operation, which can quickly improve the viewing conditions of the high-precision display panel 102. In addition, the sliding seat 300 slides smoothly along the sliding groove 301 to ensure that the position of the light-shielding ring 200 is stable after popping out and the light-shielding range is accurate, avoiding the instability of the light-shielding effect due to shaking, and further ensuring the reliability of information recognition under strong light.

[0022] The connector includes through holes 205 respectively opened on the lower inner wall of the two sides of the light-shielding ring 200. The inner cavity of the two sets of through holes 205 is respectively inserted with fixing bolts 204. The screws of the two sets of fixing bolts 204 pass through the corresponding side through holes 205 and are threaded to the surface of the corresponding side sliding seat 300. Through the setting of the connector, the fixing bolts 204 and the through holes 205 are used to connect the light-shielding ring 200 and the sliding seat 300. The connection method is simple and reliable, which can ensure that the light-shielding ring 200 is firmly connected to the sliding seat 300 during the movement and is not easy to loosen. At the same time, the connection between the light-shielding ring 200 and the sliding seat 300 can be released by removing the fixing bolts 204, which facilitates the replacement or maintenance of the light-shielding ring 200 and makes maintenance convenient.

[0023] The locking mechanism includes inserts 303 fixedly connected to the bottom of each set of sliding seats 300. The bottom of the sliding groove 301 has slots 305 for the inserts 303 to be inserted into. Inside the watch case 100, and within each set of slots 305, there are horizontally arranged circular grooves 406. Sliding discs 401 are slidably connected to the inner cavities of both sets of circular grooves 406. Return springs 404 are connected to opposite ends of the two sets of sliding discs 401. Each set of two sets of positioning rods 400 is fixedly connected to one end of the back. The opposite ends of the two sets of positioning rods 400 can be slidably inserted into the inner cavity of the corresponding side slots 305. The bottom of the opposite side of each set of inserts 303 is provided with a insertion hole 304. The lower corners of the opposite ends of the two sets of inserts 303 are beveled. When the insert 303 enters the slot 305 downwards, the positioning rod 400 needs to be temporarily retracted by pressing it with the bevel until the insertion hole 304 is aligned with the end of the positioning rod 400. The positioning rods 400 are inserted into the inner cavities of the corresponding side insertion holes 304 under the push of the corresponding side return springs 404. The bottom of the watch case 100 is provided with a sliding disc 401 that moves to the opposite side to compress the spring and cause the positioning rods 400 to slide out of the slots 305. Through the cooperation of the insert 303, the slots 305, the positioning rods 400 and the return springs 404, the light-shielding ring 200 can be stably locked in the mounting groove 104 when it is stored, preventing the light-shielding ring 200 from being blocked. The 00 slides out automatically upon accidental contact, enhancing structural safety. Furthermore, the beveled design at the bottom of the insert 303 allows it to automatically press the positioning rod 400 to retract when the light-shielding ring 200 is pressed for storage, eliminating the need for manual operation of the locking mechanism and simplifying the storage process. Additionally, the reset spring 404 ensures that the positioning rod 400 automatically pops out and inserts into the socket 304 after alignment, achieving automatic locking. The locking process is reliable and efficient.

[0024] The actuating component includes guide holes 405 located at the bottom of the watch case 100 and below each set of circular grooves 406. The two sets of guide holes 405 are respectively connected to the corresponding side circular grooves 406. The bottom of the two sets of sliding discs 401 are respectively fixedly connected to connecting pieces 402. The bottom of the two sets of connecting pieces 402 passes through the corresponding side guide holes 405 and is fixedly connected to a lever 403. The two sets of levers 403 are respectively slidably connected to the bottom surface of the watch case 100. Through the setting of the actuating component, the cooperation between the lever 403 and the connecting piece 402 makes the unlocking operation intuitive and convenient. When strong light suddenly shines and causes reflection, the operator can quickly move the lever 403 to make the light shield 200 pop out, block the strong light in time, and reduce the difficulty of information recognition caused by operation delay.

[0025] The snap-fit ​​component includes a slot 202 formed on the top surface of the light-shielding ring 200. A retaining ring 203 is snapped into the inner cavity of the slot 202. The retaining ring 203 is fixedly connected to the bottom surface of the protective sheet 201. Through the snap-fit ​​component, the snap-fit ​​structure between the slot 202 and the retaining ring 203 makes it easy to install and remove the protective sheet 201. In strong light environments, it will not hinder the light-shielding ring 200 from popping out to shield the light. At the same time, the protective sheet 201 can prevent dust and impurities from adhering to the surface of the high-precision display panel 102, avoid the impurities and strong light from working together to aggravate reflection, and indirectly improve display clarity. Moreover, the cooperation between the protective sheet 201 and the light-shielding ring 200 does not affect the light-shielding effect.

[0026] The outer circular surface of the light-shielding ring 200 is fixedly connected with several sets of limiting protrusions 101. The inner wall of the mounting groove 104 and the corresponding position of each set of limiting protrusions 101 are provided with limiting grooves 103 for sliding of the limiting protrusions 101. This is to prevent the light-shielding ring 200 from rotating circumferentially within the mounting groove 104. Through the setting of the limiting protrusions 101, the cooperation between the limiting protrusions 101 and the limiting grooves 103 can limit the circumferential rotation of the light-shielding ring 200, ensuring that the light-shielding ring 200 always surrounds the high-precision display panel 102 to form a precise light-shielding range after it pops out. This avoids some areas being exposed to strong light and causing reflection due to rotation, ensuring the comprehensiveness of light shielding. At the same time, the limiting structure assists the light-shielding ring 200 to move smoothly, making the light-shielding function stable and reliable under strong light.

[0027] Working principle; When strong light shines on the high-precision display panel 102, the toggle block 403 is moved in the opposite direction. The toggle block 403 drives the sliding disk 401 in the circular groove 406 to move through the connecting piece 402. The sliding disk 401 compresses the reset spring 404 and drives the positioning rod 400 to exit from the insertion hole 304 of the insertion strip 303, thus releasing the locked state. At this time, the push spring 302 in the sliding groove 301 releases elastic potential energy and pushes the sliding seat 300 upward. The sliding seat 300 drives the light-shielding ring 200 to move upward through the connector, so that the light-shielding ring 200 slides out of the mounting groove 104 to block strong light, thereby making it easier for people to watch. When the light-shielding ring 200 is pressed down, the inserts 303 connected to the bottom of its two sides move down and enter the slots 305 at the bottom of the sliding groove 301. The chamfer on the lower side of one end of the insert 303 will press the positioning rod 400 in the circular groove 406, causing the positioning rod 400 to drive the sliding plate 401 to compress the return spring 404 and temporarily retract into the circular groove 406; When the insert 303 moves down until the insertion hole 304 on its surface is aligned with the position of the positioning rod 400, the reset spring 404 resets and pushes the sliding plate 401, causing the positioning rod 400 to extend and insert into the insertion hole 304, thus locking the insert 303 and fixing the light shielding ring 200 in the mounting groove 104 for storage. When the light-shielding ring 200 is damaged, push the protective plate 201 upward to disengage the retaining ring 203 at its bottom from the inner cavity of the retaining groove 202. Then, remove the fixing bolts 204 located on both sides to disconnect the light-shielding ring 200 from the sliding seat 300. Then, take out a new light-shielding ring 200, align the through holes 205 on both sides with the sliding seat 300, and use fixing bolts 204 to insert into the corresponding through holes 205 and connect them to the corresponding sliding seat 300, thereby completing the replacement of the light-shielding ring 200.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
