A stable and reliable self-locking mechanism for the battery cover of an electronic scale

Abstract

This invention relates to the field of battery cover self-locking technology, and specifically discloses a stable and reliable electronic scale battery cover self-locking mechanism. This stable and reliable electronic scale battery cover self-locking mechanism is equipped with a locking mechanism. Compared with screw fixing, this structure does not require tools such as screwdrivers to disassemble the battery cover. The cover can be separated from the scale body through a series of operations such as pushing the sliding plate, making the operation simpler and faster, saving users time and effort in disassembling the battery cover, and improving ease of use. Compared with magnetic snap-fit, this structure, when fixing the cover, in addition to the magnetic attraction between the connecting pin and the magnetic cylinder, also has multiple components such as locking rods and locking pins that cooperate with the scale body and the cover, forming multiple limits and fixation. This effectively prevents the battery cover from falling off due to external forces such as tilting or bumping during the use of the electronic scale, ensuring the stability and reliability of the battery cover under normal use.

Description

Technical Field

[0001] This invention relates to the field of battery cover self-locking technology, specifically to a stable and reliable electronic scale battery cover self-locking mechanism. Background Technology

[0002] An electronic scale is a weighing instrument that uses electronic technology to measure and display the weight of an object. It mainly consists of a load cell, a measuring circuit, and a microprocessor. When an object is placed on the weighing pan, the load cell is subjected to pressure, causing the elastic element inside to deform. This deformation changes the resistance of the strain gauge attached to the elastic element, converting the object's weight into an electrical signal. The measuring circuit amplifies and filters this weak electrical signal from the load cell, converting it into a digital signal and transmitting it to the microprocessor. The microprocessor calculates and processes the received digital signal according to a pre-set algorithm, ultimately determining the object's weight and displaying it on the screen.

[0003] Most electronic scales are equipped with batteries and battery covers to secure them. The battery covers of most electronic scales are fixed by magnetic clips, screws, or a combination of both. While screws are a secure method for fixing the battery cover, tools are needed to remove it, which is inconvenient. Although magnetic clips are easier to install, when one foot is on the electronic scale, it may cause the scale to tilt and bump, and the cover may fall off due to the external force generated by the tilt. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stable and reliable self-locking mechanism for the battery cover of an electronic scale, comprising:

[0005] The scale body has a display screen fixedly connected to its top and a support component fixedly connected to its bottom;

[0006] A cover plate component, wherein the side of the cover plate component is movably connected to the inner side of the scale body;

[0007] The cover plate component includes a cover plate, a locking mechanism is slidably connected to the inner side of the cover plate, a connecting plate is fixedly connected to the top of the cover plate, a flow guiding mechanism is fixedly connected to the inner side of the connecting plate, a collection mechanism is fixedly connected to the bottom of the flow guiding mechanism, and a fixing mechanism is slidably connected to the top of the connecting plate.

[0008] The locking mechanism includes a sliding component and a guide groove. The guide groove is cross-shaped and located inside the cover plate. The sides of the two locking rods are slidably connected to the horizontally arranged guide groove. Both sides of the sliding component are rotatably connected to connecting rods. A slider is rotatably connected to the side of the connecting rod away from the sliding component. The guide groove is evenly located inside the cover plate. Locking rods are slidably connected to the inside of the guide groove. The inside of the locking rods is fixedly connected to the side of the slider. A sliding groove is provided in the middle of the inside of the cover plate. A magnetic cylinder is fixedly connected to the side of the cover plate near the sliding groove.

[0009] When removing the battery cover from the electronic scale, place the top of the electronic scale horizontally on the ground with the cover facing you.

[0010] By pushing the sliding plate towards the support component, the sliding plate moves the moving plate into the slide groove via the fixed pin. When the moving plate moves, the connecting rod on both sides pulls the connecting rod, which in turn moves the locking rod in the horizontal guide groove via the slider. This causes the end of the locking rod that abuts against the scale body to disengage from the corresponding hole in the inner wall of the battery compartment in the scale body and enter the cover plate. As a result, the locking rods on both sides release the limiting fixation between the cover plate and the scale body.

[0011] Preferably, the sliding assembly includes a sliding plate, the top of which is slidably connected to the bottom of the cover plate. A movable plate is fixedly connected to the top of the sliding plate by a fixing pin. The side of the movable plate is slidably connected to the inner side of the slide groove. Connecting rods are fixedly connected to both sides of the movable plate. The end of the connecting rod away from the slider is rotatably connected to the end of the connecting rod away from the movable plate. A connecting pin is fixedly connected to the side of the movable plate away from the connecting rod. A locking pin is fixedly connected to the side of the movable plate away from the connecting pin. The locking pin and the connecting pin are slidably connected to the inner side of the vertically arranged guide 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 pressing plate is slidably connected to the side of the locking pin. The side of the pressing plate is fixedly connected to the inner side of the vertically arranged guide groove.

[0012] As the moving plate follows the sliding plate and moves towards the chute, the moving plate causes the locking pin to slide in the longitudinal guide groove, disengaging from the corresponding hole on the inner wall of the battery compartment in the scale body and entering the cover plate. As the locking pin moves towards the cover plate, it simultaneously compresses the second spring. At the same time, the connecting pin moves with the moving plate in the cover plate, causing the connecting pin to enter the magnet cylinder. This causes the side of the connecting pin to be magnetically attracted to the inside of the magnet cylinder, thus fixing the position of the connecting pin. The connecting pin also fixes the positions of the moving plate and the sliding plate.

[0013] When it is necessary to reinstall the cover plate and the scale body, simply reverse the operation. A magnetic strip is set on the side of the cover plate away from the locking pin, so the position of the locking pin can be quickly identified when installing the cover plate into the scale body. At the same time, when the cover plate is placed in the scale body, the magnetic strip on the side of the cover plate attracts the inside of the battery compartment, which helps to roughly limit the position of the cover plate. This helps to quickly and accurately restore each component to its original position, making the installation process smoother and reducing the possibility of misalignment during installation.

[0014] Preferably, the fixing mechanism includes a fixing plate, fixing claws are fixedly connected to both sides of the top of the fixing plate, a locking block is fixedly connected to the middle of the top of the fixing plate, through holes are evenly opened on the side of the fixing plate, a connecting shaft is fixedly connected to the bottom of the fixing plate, a positioning plate is slidably connected to the bottom of the connecting shaft, the top of the positioning plate is fixedly connected to the bottom of the cover plate, a third spring is sleeved on the connecting shaft, the top of the third spring is fixedly connected to the bottom of the fixing plate, and the bottom of the third spring is fixedly connected to the top of the connecting plate.

[0015] When the cover plate is installed in the scale body, the connecting plate drives the fixing plate to abut against the battery in the battery compartment. The fixing plate is provided with arc-shaped fixing claws on both sides and a locking block in the middle of the fixing plate. The fixing plate is pressed tightly against the battery by the action of the third spring, thereby fixing and limiting the battery in the battery compartment.

[0016] The fixing plate is pressed tightly against 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 vibration and collision that the electronic scale may be subjected to during use, this fixing method can ensure that the battery always stays in the correct position, ensure the normal operation of the electronic scale, and avoid problems such as poor circuit contact caused by loose battery.

[0017] Preferably, the flow guiding mechanism includes flow guiding grooves, which are evenly opened on the side of the connecting plate, and inclined grooves are symmetrically arranged on the inner side of the flow guiding grooves, and a square groove is opened in the middle of the flow guiding grooves.

[0018] Electronic scales may remain idle for extended periods, causing the battery to remain stationary inside the scale. Even when not in use, the battery will still undergo self-discharge and internal chemical reactions. Over time, this can lead to electrolyte deterioration, changes in internal battery pressure, and ultimately, leakage.

[0019] By providing a flow guide groove and an inclined groove on the side of the connecting plate near the battery, when the battery leaks, the liquid can flow into the flow guide groove through the inclined grooves on both sides of the flow guide groove, and then enter the collection mechanism below the square groove to collect the leaked battery liquid.

[0020] Concentrating the leak in the square tank makes it easier to treat the leak centrally, preventing it from spreading to hard-to-clean corners and crevices. This reduces the difficulty of cleaning and maintenance, and subsequent maintenance only requires cleaning the leak in the square tank, thus improving maintenance efficiency.

[0021] By guiding the leaking liquid into the square groove, the leaking liquid is prevented from being exposed to the outside, reducing the possibility of users accidentally coming into contact with the leaking liquid. Battery leakage can cause harm to human skin and eyes, and this design helps to protect the safety and health of users, especially during the daily use of electronic scales, reducing the risk of users being injured by leakage.

[0022] Preferably, the collecting mechanism includes a collecting shell, which is disposed below the square groove. The side of the collecting shell is fixedly connected to the inner side of the connecting plate. A square plate is fixedly connected to the inner side of the collecting shell. A sensing module is fixedly connected to the center of the top of the square plate. A sponge board is fixedly connected to the bottom of the inner cavity of the collecting shell.

[0023] When the battery leaks, the liquid enters the collection housing through the square groove. A sensing module is installed on the side of the collection housing. When the leaked liquid flows onto the surface of the liquid sensor in the sensing module, a conductive path is formed between the electrodes of the liquid sensor, thereby generating a change in electrical signal. This determines whether the battery is leaking. When the liquid sensor detects the leak signal, it issues a command, and the control circuit will display a prominent text prompt on the display screen, such as "Battery leak, please deal with it immediately." It can also use icons or symbols for more intuitive prompts. At the same time, a sponge plate is installed at the bottom of the inner cavity of the collection housing to absorb and collect the liquid that enters the collection housing.

[0024] It can effectively collect the leaking liquid flowing in through the square groove. The sponge board can absorb and collect the liquid entering the collection shell, preventing the leaking liquid from flowing around inside the electronic scale, avoiding secondary pollution and corrosion to other parts of the electronic scale, protecting other parts and circuits inside the electronic scale, and extending the service life of the electronic scale.

[0025] This invention provides a stable and reliable self-locking mechanism for the battery cover of an electronic scale. It has the following advantages:

[0026] 1. This stable and reliable electronic scale battery cover self-locking mechanism is equipped with a locking mechanism. Compared with screw fixing, this structure does not require the use of screwdrivers or other tools to remove the battery cover. The cover can be separated from the scale body by pushing the sliding plate and other operations, making the operation simpler and faster, saving users time and effort in removing the battery cover, and improving the convenience of use. Compared with magnetic buckles, this structure, in addition to the magnetic attraction between the connecting pin and the magnetic cylinder, also has multiple components such as locking rods and locking pins that cooperate with the scale body and the cover to form multiple limits and fixation. It can effectively prevent the battery cover from falling off due to external forces such as tilting or bumping during the use of the electronic scale, ensuring the stability and reliability of the battery cover under normal use, and reducing problems such as battery loosening and damage that may be caused by the back cover falling off.

[0027] 2. This stable and reliable electronic scale battery cover self-locking mechanism is equipped with a sliding component. Not only does it have a locking rod to limit and fix the cover plate and the scale body, but it also has a locking pin that slides in the longitudinal guide groove and enters the cover plate when the moving plate moves to further strengthen the fixing effect. This forms a double fixing mechanism, which ensures 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 measurement errors that may be caused by loose parts.

[0028] 3. This stable and reliable electronic scale battery cover self-locking mechanism is equipped with a flow guiding mechanism. When the battery leaks, the design of the flow guiding groove and the inclined groove can guide the leaked liquid to flow along a specific path, so that the liquid flows into the flow guiding groove along the inclined groove and then into the square groove, preventing the leaked liquid from flowing randomly inside the electronic scale and preventing the liquid from contacting other electronic components. This reduces the risk of short circuits, corrosion and other failures caused by leakage, and protects the overall performance and service life of the electronic scale.

[0029] 4. This stable and reliable self-locking mechanism for the battery cover of an electronic scale is equipped with a fixing mechanism. The arc-shaped fixing claws can better fit the shape of the battery, providing a tight fixation regardless of whether the battery is cylindrical or other common shapes. At the same time, the central locking block can further enhance the constraint on the battery, limiting the battery from multiple directions, improving the adaptability to different battery specifications. This structure can be used for various types of batteries. Through the pressing of the battery by the fixing plate and the limiting effect of the fixing claws and locking blocks, the battery can be effectively prevented from falling out of the battery slot when the electronic scale is tilted or subjected to large external forces, ensuring the stability and safety of the battery under various conditions, and preventing the battery from loosening and falling out, which would cause the battery cover to loosen.

[0030] 5. This stable and reliable electronic scale battery cover self-locking mechanism is equipped with a collection mechanism. Leakage is collected on a sponge plate inside the collection shell, making it convenient for users to centrally handle leakage. Compared with the situation where leakage is scattered in various places and difficult to clean, this design makes the cleaning work more convenient. Users can directly handle the collection shell and sponge plate, reducing the difficulty and workload of cleaning. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-7 This invention provides a technical solution: a stable and reliable self-locking mechanism for the battery cover of an electronic scale, comprising:

[0044] The scale body 1 has a display screen 2 fixedly connected to its top and a support component 3 fixedly connected to its bottom.

[0045] Cover plate component 4, the side of cover plate component 4 is movably connected to the inside of the scale body 1;

[0046] Please see Figures 1-5 The cover plate component 4 includes a cover plate 41, a locking mechanism 42 is slidably connected to the inner side of the cover plate 41, a connecting plate 44 is fixedly connected to the top of the cover plate 41, a flow guiding mechanism 47 is fixedly connected to the inner side of the connecting plate 44, a collection mechanism 46 is fixedly connected to the bottom of the flow guiding mechanism 47, and a fixing mechanism 45 is slidably connected to the top of the connecting plate 44.

[0047] Please see Figures 1-6The locking mechanism 42 includes a sliding component 421 and a guide groove 427. The guide groove 427 is cross-shaped and is located inside the cover plate 41. The sides of the two locking rods 422 are slidably connected to the guide groove 427. Both sides of the sliding component 421 are rotatably connected to connecting rods 424. The side of the connecting rods 424 away from the sliding component 421 is rotatably connected to a slider 423. The guide groove 427 is evenly located inside the cover plate 41. The inner side of the guide groove 427 is slidably connected to the locking rods 422. The inner side of the locking rods 422 is fixedly connected to the side of the slider 423. A sliding groove 425 is provided in the middle of the inner side of the cover plate 41. A magnetic cylinder 426 is fixedly connected to the side of the cover plate 41 near the sliding groove 425.

[0048] Specifically, when removing the battery cover of the electronic scale, place the top of the electronic scale horizontally on the ground with the cover plate 41 facing you.

[0049] By pushing the sliding plate 4211 to slide towards the support component 3, the sliding plate 4211 drives the moving plate 4212 to move towards the slide groove 425 through the fixed pin. 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 transverse guide groove 427 through the slider 423. This causes the end of the locking rod 422 that abuts against the scale body 1 to disengage from the corresponding hole in the inner wall of the battery compartment in the scale body and enter the cover plate 41. Thus, the locking rods 422 on both sides release the limiting fixation between the cover plate 41 and the scale body 1.

[0050] Please see Figures 1-7 The sliding assembly 421 includes a sliding plate 4211, the top of which is slidably connected to the bottom of the cover plate 41. A movable plate 4212 is fixedly connected to the top of the sliding plate 4211 by a fixing pin. The side of the movable plate 4212 is slidably connected to the inner side of the slide groove 425. Connecting rods 4214 are fixedly connected to both sides of the movable plate 4212. The end of the connecting rod 4214 away from the slider 423 is rotatably connected to the end of the connecting rod 4214 away from the movable plate 4212. A connecting pin 4215 is fixedly connected to the side of the movable plate 4212 away from the connecting rod 4214. A locking pin 4216 is fixedly connected to one side of the connecting pin 4215. Both the locking pin 4216 and the connecting pin 4215 are slidably connected to the inner side of the vertically arranged guide groove 427. A circular plate 4217 is fixedly connected to the side of the locking pin 4216. A second spring 4218 is sleeved on the locking pin 4216. One end of the second spring 4218 is fixedly connected to the circular plate 4217, and the other end of the second spring 4218 is fixedly connected to the side of the pressing plate 4219. The pressing plate 4219 is slidably connected to the side of the locking pin 4216, and the side of the pressing plate 4219 is fixedly connected to the inner side of the vertically arranged guide groove 427.

[0051] Specifically, when the moving plate 4212 follows the sliding plate 4211 and moves towards the slide groove 425, the moving plate 4212 causes the locking pin 4216 to slide in the longitudinal guide groove 427, disengaging from the corresponding hole on the inner wall of the battery compartment in the scale body 1 and entering the cover plate 41. When the locking pin 4216 moves towards the cover plate 41, it simultaneously compresses the second spring 4218. At the same time, the connecting pin 4215 follows the moving plate 4212 and moves in the cover plate 41, causing the connecting pin 4215 to enter the magnet cylinder 426. This causes the side of the connecting pin 4215 to be magnetically attracted to the inner side of the magnet cylinder 426, thereby fixing the position of the connecting pin 4215. The connecting pin 4215 also fixes the positions of the moving plate 4212 and the sliding plate 4211.

[0052] When it is necessary to reinstall the cover plate 41 and the scale body 1, simply reverse the operation. By setting a magnetic strip on the side of the cover plate 41 away from the locking pin 4216, the position of the locking pin 4216 can be quickly identified when the cover plate 41 is installed in the scale body 1. At the same time, when the cover plate 41 is placed in the scale body 1, the magnetic strip on the side of the cover plate 41 attracts the inside of the battery compartment, which makes it easy to roughly limit the position of the cover plate 41. This helps to quickly and accurately restore each component to its original position, making the installation process smoother and reducing problems such as misalignment that may occur during the installation process.

[0053] Please see Figures 1-8 The present invention provides a technical solution:

[0054] The fixing mechanism 45 includes a fixing plate 451, fixing claws 452 fixedly connected to both sides of the top of the fixing plate 451, a locking block 453 fixedly connected to the middle of the top of the fixing plate 451, through holes 454 evenly opened on the side of the fixing plate 451, a connecting shaft 456 fixedly connected to the bottom of the fixing plate 451, a positioning plate 457 slidably connected to the bottom of the connecting shaft 456, the top of the positioning plate 457 fixedly connected to the bottom of the cover plate 41, a third spring 458 sleeved on the connecting shaft 456, the top of the third spring 458 fixedly connected to the bottom of the fixing plate 451, and the bottom of the third spring 458 fixedly connected to the top of the connecting plate 44.

[0055] Specifically, when the cover plate 41 is installed in the scale body 1, the connecting plate 44 drives the fixing plate 451 to abut against the battery in the battery slot. By providing arc-shaped fixing claws 452 on both sides of the fixing plate 451 and a locking block 453 in the middle of the fixing plate 451, the fixing plate 451 is pressed tightly against the battery under the action of the third spring 458, thereby fixing and limiting the battery in the battery slot.

[0056] The fixing plate 451 is pressed tightly against the battery under the action of the third spring 458, which can effectively prevent the battery from shaking or shifting in the battery slot. Especially for the vibration and collision that the electronic scale may be subjected to during use, this fixing method can ensure that the battery is always kept in the correct position, ensuring the normal operation of the electronic scale and avoiding problems such as poor circuit contact caused by loose battery.

[0057] Please see Figures 1-9 The present invention provides a technical solution:

[0058] The flow guiding mechanism 47 includes a flow guiding groove 471, which is evenly opened on the side of the connecting plate 44. Inclined grooves 472 are symmetrically arranged on the inner side of the flow guiding groove 471, and a square groove 473 is opened in the middle of the flow guiding groove 471.

[0059] Specifically, if the electronic scale is left unused for a long time, the battery may remain in a static state inside the scale body 1. Even if the battery is not used, it will still have self-discharge and internal chemical reactions. Over time, this may lead to electrolyte deterioration, changes in internal battery pressure, etc., which may cause leakage.

[0060] By providing a guide groove 471 and an inclined groove 472 on the side of the connecting plate 44 near the battery, when the battery leaks, the liquid can flow into the guide groove 471 through the inclined groove 472 on both sides of the guide groove 471, and then enter the collection mechanism 46 below the square groove 473 to collect the leaked battery liquid.

[0061] By guiding the leaking liquid into the square groove 473, the leaking liquid is prevented from being exposed to the outside, reducing the possibility of users accidentally coming into contact with the leaking liquid. Battery leakage may cause harm to human skin and eyes, etc. This design helps to protect the safety and health of users, especially during the daily use of electronic scales, reducing the risk of users being injured by leakage.

[0062] Please see Figures 1-10 The present invention provides a technical solution:

[0063] The collection mechanism 46 includes a collection housing 461, which is disposed below the square groove 473. The side of the collection housing 461 is fixedly connected to the inner side of the connecting plate 44. A square plate 462 is fixedly connected to the inner side of the collection housing 461. A sensing module 463 is fixedly connected to the middle of the top of the square plate 462. A sponge plate 464 is fixedly connected to the bottom of the inner cavity of the collection housing 461.

[0064] Specifically, when the battery leaks, the liquid enters the collection housing 461 through the square groove 473. A sensing module 463 is provided on the side of the collection housing 461. When the leaked liquid flows to the surface of the liquid sensor in the sensing module 463, a conductive path is formed between the electrodes of the liquid sensor, thereby generating a change in electrical signal to determine whether the battery is leaking. When the liquid sensor detects the leakage signal, it issues a command, and the control circuit will display a prominent text prompt on the display screen 2, such as "Battery leakage, please deal with it immediately". It can also be accompanied by icons or symbols for more intuitive prompts. At the same time, a sponge plate 464 is provided at the bottom of the inner cavity of the collection housing 461, which can absorb and collect the liquid that enters the collection housing 461.

[0065] It can effectively collect the leakage liquid flowing in through the square groove 473. The sponge plate 464 can absorb and collect the liquid entering the collection shell 461, preventing the leakage liquid from flowing around inside the electronic scale, avoiding secondary pollution and corrosion of other parts of the electronic scale, protecting other parts and circuits inside the electronic scale, and extending the service life of the electronic scale.

[0066] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
