Description

Technical Field

[0001] The present invention relates to the technical field of battery cover self-locking, and specifically to a stable and reliable self-locking mechanism for the battery cover of an electronic scale. Background Art

[0002] An electronic scale is a weighing instrument that uses electronic technology to measure and display the weight of an object. An electronic scale mainly consists of a weighing sensor, a measurement circuit, a microprocessor, etc. When an object is placed on the weighing pan, the weighing sensor is subjected to pressure, and the elastic body inside it deforms, thereby causing a change in the resistance value of the resistance strain gauge pasted on the elastic body, thus converting the weight of the object into an electrical signal. The measurement circuit amplifies, filters, etc. the weak electrical signal output by the sensor, and then converts it into a digital signal and transmits it to the microprocessor. The microprocessor calculates and processes the received digital signal according to a pre-set algorithm, finally obtains the weight value of the object, and displays it on the display screen.

[0003] Currently, most electronic scales are generally provided with a battery and a battery cover for fixing the battery. The battery back cover of most electronic scales adopts a fixing method of magnetic snap, screws or a combination of both. Although the method of fixing the battery cover with screws is firm, tools are required to disassemble the battery cover, which is rather inconvenient. Although the magnetic snap is relatively convenient to install, when using the electronic scale, when one foot steps on the electronic scale, sometimes the electronic scale may tilt and bump, so that under the external force generated by the tilt of the electronic scale, the back cover may fall off. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A stable and reliable self-locking mechanism for the battery cover of an electronic scale, comprising: A weighing body, on the top of which a display screen is fixedly connected, and on the bottom of which a supporting component is fixedly connected; A cover plate component, the side of which is movably connected to the inside of the weighing body; The cover plate component includes a cover plate, inside which a locking mechanism is slidably connected, on the top of which a connecting plate is fixedly connected, inside which a diversion mechanism is fixedly connected, at the bottom of which a collection mechanism is fixedly connected, and on the top of which a fixing mechanism is slidably connected; The locking mechanism includes a sliding component and a guiding groove. The guiding groove is cross-shaped and formed in the inner side of the cover plate. The sides of the two locking rods are slidably connected to the horizontally arranged guiding groove. Connecting rods are rotatably connected to both sides of the sliding component. One side of the connecting rod away from the sliding component is rotatably connected to a slider. The guiding grooves are evenly formed in the inner side of the cover plate. The inner side of the guiding groove is slidably connected to a locking rod. The inner side of the locking rod is fixedly connected to the side of the slider. A chute is formed in the middle of the inner side of the cover plate. A magnet cylinder is fixedly connected to one side of the cover plate close to the chute; When disassembling the battery back cover of the electronic scale, place the top of the electronic scale horizontally on the ground and face the cover plate towards yourself; By pushing the sliding plate to slide in the direction of the support component, the sliding plate drives the moving plate through the fixing pin to move towards the chute. When the moving plate moves, the connecting rods are pulled by the connecting rods on both sides, so that the connecting rods drive the locking rods to move in the horizontal guiding groove through the sliders, so that the end of the locking rod in contact with the weighing body disengages from the corresponding holes in the inner wall of the battery slot in the weighing body and enters the cover plate, so that the two locking rods release the limit fixation between the cover plate and the weighing body; Preferably, the sliding component includes a sliding plate. The top of the sliding plate is slidably connected to the bottom of the cover plate. The top of the sliding plate is fixedly connected to a moving plate through a fixing pin. The side of the moving plate is slidably connected to the inner side of the chute. Connecting rods are fixedly connected to both sides of the moving plate. One end of the connecting rod away from the slider is rotatably connected to one end of the connecting rod away from the moving plate. A connecting pin is fixedly connected to one side of the moving plate away from the connecting rod. A locking pin is fixedly connected to one side of the moving plate away from the connecting pin. Both the locking pin and the connecting pin are slidably connected to the inner side of the vertically arranged guiding groove. A circular plate is fixedly connected to the side of the locking pin. A second spring is sleeved on the locking pin. One end of the second spring is fixedly connected to the circular plate. The other end of the second spring is fixedly connected to the side of the pressing plate. The side of the locking pin is slidably connected to a pressing plate. The side of the pressing plate is fixedly connected to the inner side of the vertically arranged guiding groove; When the moving plate follows the sliding plate and moves towards the chute, the moving plate drives the locking pin to slide in the vertical guiding groove, disengaging from the corresponding holes in the inner wall of the battery slot in the weighing body and entering the cover plate. When the locking pin moves into the cover plate, the second spring is compressed at the same time. At the same time, the connecting pin follows the moving plate to move in the cover plate, so that the connecting pin enters the magnet cylinder, so that the side of the connecting pin is magnetically attracted to the inner side of the magnet cylinder, so as to fix the position of the connecting pin. At the same time, the positions of the moving plate and the sliding plate are fixed through the connecting pin; When it is necessary to reinstall the cover plate and the weighing body, just operate in the reverse direction. By setting a magnetic strip on the side of the cover plate away from the locking pin, when installing the cover plate in the weighing body, the position of the locking pin can be quickly identified. At the same time, when placing the cover plate in the weighing body, the magnetic strip on the side of the cover plate attracts the inner side of the battery slot, which is convenient for roughly limiting the position of the cover plate, and can help quickly and accurately restore each component to its original position, making the installation process smoother and reducing problems such as inaccurate alignment that may occur during the installation process; Preferably, the fixing mechanism includes a fixing plate. Both sides of the top of the fixing plate are fixedly connected with fixing claws. The middle of the top of the fixing plate is fixedly connected with a clamping block. The side of the fixing plate is evenly provided with through holes. The bottom of the fixing plate is fixedly connected with a connecting shaft. The bottom of the connecting shaft is slidably connected with a positioning plate. The top of the positioning plate is fixedly connected with the bottom of the cover plate. A third spring is sleeved on the connecting shaft. The top of the third spring is fixedly connected with the bottom of the fixing plate. The bottom of the third spring is fixedly connected with the top of the connecting plate; When installing the cover plate in the weighing body, the connecting plate drives the fixing plate to abut against the battery in the battery slot. By providing arc-shaped fixing claws on both sides of the fixing plate and a clamping block in the middle of the fixing plate, the fixing plate tightly presses on the battery under the action of the third spring, so as to fix and limit the battery in the battery slot; The fixing plate tightly presses on the battery under the action of the third spring, which can effectively prevent the battery from shaking or shifting in the battery slot. Especially for the vibrations, collisions, etc. that the electronic scale may receive during use, this fixing method can ensure that the battery always remains in the correct position, guarantee the normal operation of the electronic scale, and avoid problems such as poor electrical contact caused by the loosening of the battery; Preferably, the diversion mechanism includes diversion grooves. The diversion grooves are evenly opened on the side of the connecting plate. Inclined grooves are symmetrically arranged on the inner side of the diversion grooves. A square groove is opened in the middle of the diversion grooves; The electronic scale may be idle for a long time, and the battery remains static in the weighing body for a long time. Even if the battery is not used, there will be self-discharge and internal chemical reactions, which may lead to electrolyte deterioration, battery internal pressure changes, etc. in the long run, thus causing leakage; By opening diversion grooves and inclined grooves on the side of the connecting plate close to the battery, when the battery leaks, the liquid can flow into the diversion grooves through the inclined grooves on both sides of the diversion grooves, and then enter the collection mechanism below the square groove to collect the leaked battery liquid; The leaked liquid is concentrated in the square groove, which is convenient for centralized treatment of the leaked liquid and prevents the leaked liquid from spreading to corners and gaps that are difficult to clean. This reduces the difficulty of cleaning and maintenance. In subsequent maintenance, only the leaked liquid in the square groove needs to be cleaned, which improves maintenance efficiency. The leaked liquid is guided into the square groove to avoid being exposed to the outside, reducing the possibility of accidental contact with the leaked liquid by the user. Battery leakage may cause damage to human skin and eyes. This design helps to protect the safety and health of users, especially in the daily use of electronic scales, reducing the risk of users being harmed by leakage. Preferably, the collecting mechanism comprises a collecting shell, the collecting shell is arranged below the square groove, the side of the collecting shell is fixedly connected to the inner side of the connecting plate, the inner side of the collecting shell is fixedly connected to a square plate, the middle part of the top of the square plate is fixedly connected to a sensing module, and the bottom of the inner cavity of the collecting shell is fixedly connected to a sponge plate; When the battery leaks, it enters the collection shell through the square groove. By setting a sensing module on the side of the collection shell, when the leaked liquid flows to the surface of the liquid sensor in the sensing module, a conductive path will be formed between the electrodes of the liquid sensor, thereby generating an electrical signal change, so as to judge whether the battery is leaking. When the liquid sensor detects the leakage signal, it will issue an instruction, and the control circuit will display a striking text prompt on the display screen, such as "Battery leakage, please deal with it immediately" and other information, and it can be combined with icons or symbols for more intuitive prompts. At the same time, a sponge plate is set at the bottom of the inner cavity of the collection shell, which can absorb and collect the liquid entering the collection shell; It can effectively collect the leaked liquid flowing in through the square groove. The sponge board can absorb and collect the liquid entering the collection shell to prevent the leaked liquid from flowing around inside the electronic scale, avoid the leakage from causing secondary pollution and corrosion to other parts of the electronic scale, protect other parts and circuits inside the electronic scale, and extend the service life of the electronic scale.

[0005] The present invention provides a stable and reliable electronic scale battery cover self-locking mechanism, which has the following beneficial effects: 1. The self-locking mechanism for the battery cover of a stable and reliable electronic scale is provided with a locking mechanism. Compared with the screw fixation method, this structure does not require tools such as screwdrivers to disassemble the battery cover. By pushing the sliding plate and other operations, the separation of the cover plate and the scale body can be achieved, which is more convenient and faster in operation, saving the user's time and energy for disassembling the battery cover, improving the convenience of use. Compared with magnetic snap fasteners, when fixing the cover plate, in addition to the magnetic attraction between the connecting pin and the magnet cylinder, multiple components such as the locking rod and the locking pin cooperate with the scale body and the cover plate to form multiple limits and fixations, which can effectively prevent the battery back cover from falling off due to external forces such as tilting and bumping during the use of the electronic scale, ensuring the stability and reliability of the battery cover under normal use conditions, and reducing problems such as battery loosening and damage that may be caused by the back cover falling off.

[0006] 2. The self-locking mechanism for the battery cover of a stable and reliable electronic scale is provided with a sliding component. Not only does the locking rod limit and fix the cover plate and the scale body, but the locking pin also slides in the longitudinal guide groove and enters the cover plate when the moving plate moves to further enhance the fixing effect, forming a double fixing mechanism, so that the cover plate and the scale body can maintain a stable connection during normal use, ensuring the stability of the electronic scale structure and reducing problems such as measurement errors that may be caused by component loosening.

[0007] 3. The self-locking mechanism for the battery cover of a stable and reliable electronic scale is provided with a diversion mechanism. When the battery leaks liquid, the design of the diversion groove and the inclined groove can guide the leaked liquid to flow along a specific path, so that the liquid flows into the diversion groove along the inclined groove and then enters the square groove, avoiding the random flow of the leaked liquid inside the electronic scale and preventing the liquid from contacting other electronic components, thereby reducing the risk of failures such as short circuits and corrosion caused by liquid leakage, and protecting the overall performance and service life of the electronic scale.

[0008] 4. The self-locking mechanism for the battery cover of a stable and reliable electronic scale is provided with a fixing mechanism. The arc-shaped fixing claws can better fit the shape of the battery. Whether the battery is cylindrical or other common shapes, it can provide a relatively tight fixation. At the same time, the middle clamping block can further enhance the restraint on the battery, limit the battery from multiple directions, improve the adaptability to different specifications of batteries, so that this structure can be applied to various types of batteries. Through the pressing of the battery by the fixing plate and the limiting effect of the fixing claws and the clamping block, it can effectively prevent the battery from falling out of the battery slot when the electronic scale is tilted or subjected to a large external force, ensuring the stability and safety of the battery in various situations, and at the same time avoiding the phenomenon of the battery loosening and falling, which may cause the battery cover plate to loosen.

[0009] 5. The stable and reliable self-locking mechanism for the battery cover of the electronic scale is provided with a collection mechanism. The leaked liquid is collected on the sponge board inside the collection housing, which facilitates the user to centrally process the leaked liquid. Compared with the situation where the leaked liquid is scattered everywhere and difficult to clean, this design makes the cleaning work more convenient. The user can directly process the collection housing and the sponge board, reducing the difficulty and workload of cleaning. Description of the Drawings

When the moving plate 4212 moves, it pulls the connecting rod 424 through the connecting rods 4214 on both sides, so that the connecting rod 424 drives the locking rod 422 to move in the horizontal guiding groove 427 through the slider 423, so that the end of the locking rod 422 in contact with the scale body 1 disengages from the corresponding hole in the inner wall of the battery slot in the scale body and enters the cover plate 41, so that the two locking rods 422 release the limit fixation between the cover plate 41 and the scale body 1; Please refer to Figures 1 - 7, the sliding component 421 includes a sliding plate 4211.

When the locking pin 4216 moves into the cover plate 41, the second spring 4218 is simultaneously compressed. At the same time, the connecting pin 4215 follows the moving plate 4212 and moves in the cover plate 41, so that the connecting pin 4215 enters the magnet cylinder 426, and the side of the connecting pin 4215 is magnetically attracted to the inner side of the magnet cylinder 426, thereby fixing the position of the connecting pin 4215.

Since a magnet strip is provided on the side of the cover plate 41 away from the locking pin 4216, when the cover plate 41 is installed in the weighing body 1, the position of the locking pin 4216 can be quickly identified. At the same time, when the cover plate 41 is placed in the weighing body 1, the magnet strip on the side of the cover plate 41 is attracted to the inner side of the battery slot, facilitating the rough positioning of the position of the cover plate 41, which can help quickly and accurately restore each component to its original position, making the installation process smoother and reducing problems such as inaccurate alignment that may occur during the installation process; Please refer to Figures 1 - 8 , the present invention provides a technical solution: The fixing mechanism 45 includes a fixing plate 451.
