Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a battery cover structure of a coated plate. Background Technique

[0002] A battery cover is a mechanical structure used in mechanical assembly to prevent the battery from falling. The battery cap functions to provide battery sealing, a safety valve function, or a top cover function. Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of making a metal film adhere to the surface of metal or other material parts by electrolysis to prevent metal oxidation, such as rust. The function of coating the battery cover is to increase the wear resistance, electrical conductivity, reflectivity, corrosion resistance of the battery cover, such as copper sulfate, and to enhance the beauty, etc.

[0003] For the existing Chinese patent with the reference publication number CN111835888B, it discloses a battery cover, its preparation method and a mobile terminal. The battery cover includes a base material, an optical coating layer, and a sprayed color layer. The base material includes a main body part and a side part extending from the edge of the main body part. The main body part and the side part form a receiving groove. The base material includes an inner surface, an outer surface, and a side circumferential surface connecting the inner surface and the outer surface. The inner surface includes a first surface formed on the main body part and a second surface formed on the side part. The optical coating layer is provided on the first surface. The sprayed color layer is provided on the second surface. The color presented after the side part of the battery cover in this application is transparent can maintain a consistent depth, reducing the risk of different colors appearing after the side part of the battery cover is transparent and meeting the user's demand for the appearance effect of the battery cover.

[0004] This patent discloses a battery cover and an optical coating layer. Although it has an aesthetic effect, it does not have a structure for assisting the magnetic connection between the battery cover and the external battery compartment. It still uses the traditional buckling method. When using the buckling method, a large amount of wear will occur during the disassembly process. After reaching a certain number of times, the buckling may become loose. Therefore, the inventor of the present invention proposes a battery cover structure of a coated plate to solve the technical problem of reducing the large amount of wear generated during disassembly. Content of the Utility Model

[0005] The utility model aims to overcome the above situation and provides a technical solution that can solve the above problems.

[0006] A battery cover structure of a coated plate includes a cover body, a clamping plate, a clamping groove, and a clamping block. The clamping plate is installed at one end of the cover body and is in a convex shape. The clamping grooves are opened on the surface of the clamping plate and are symmetrical to each other. The cover body is a base layer, and a metal film layer is electroplated at one end of the base layer. A waterproof film layer is connected to one end of the metal film layer. An installation groove is opened inside the cover body, and a connection component for assisting the magnetic pairing connection between the cover body and the external battery compartment is installed inside the installation groove.

[0007] Furthermore, the connecting component includes a moving block and a reset spring. The two ends of the reset spring are respectively abutted against the moving block and one end of the installation groove. The diameter of the reset spring is smaller than that of the installation groove. The outer side surface of the moving block can slide along the inner wall of the installation groove. The highest point of one end of the moving block is lower than the surface of the installation groove. The two ends of the reset spring are respectively abutted against the moving block and one end of the installation groove. This structure ensures that the elastic restoring force of the reset spring can effectively act on the moving block, enabling it to move quickly when needed. The diameter of the reset spring is smaller than that of the installation groove. This design not only facilitates the installation and disassembly of the reset spring but also allows the reset spring to have appropriate movement space in the installation groove, increasing its service life and reliability. The highest point of one end of the moving block being lower than the surface of the installation groove prevents the moving block from colliding with the surface of the installation groove during movement, thereby reducing noise and wear.

[0008] Furthermore, one end of the moving block is a magnetic attraction block. The moving block and the magnetic attraction block are coaxially arranged. One end of the magnetic attraction block extends beyond the inner wall of the installation groove. One end of the moving block is connected with a dial for assisting the reset spring to reset. The reset spring is located on the outer side surface of the dial. One end of the dial extends beyond the surface of the cover body. A magnetic attraction groove paired with the magnetic attraction block can be opened inside the battery compartment. When the magnetic attraction block is connected to the magnetic attraction groove, the moving block is affected by the magnetic force and slides into the interior of the magnetic attraction groove, thereby playing a clamping role to prevent the surface of the cover body from falling off from the battery compartment. When manually pulling one end of the dial, the moving block is driven by the dial to move, making the magnetic attraction block flush with the surface of one end of the cover body, facilitating the disassembly of the cover body from the battery compartment.

[0009] Furthermore, the clamping block is in a convex shape and is made of rubber material. One end of the clamping block is inclined. The clamping block is installed on the surface of the cover body and is a symmetrical structure. The convex shape and rubber material of the clamping block endow it with excellent elasticity and grip. When the cover body is connected to the battery compartment, it can ensure that the cover body and the battery compartment are firmly installed and not easily fall off in the connection of the clamping block. Its inclined end makes the insertion or removal smoother, reducing the operation difficulty. The advantage of this symmetrical structure is that the clamping block can evenly distribute the force exerted by the cover body on the battery compartment, enhancing the stability and durability of the overall structure, and at the same time improving the convenience and comfort of use.

[0010] Furthermore, one end of the clamping plate is provided with a rubber block for buffering the impact force. The rubber block is in a circular arc convex shape. The advantage of the rubber block being in a circular arc convex shape is that it can effectively buffer the impact force. When the clamping plate is impacted, this circular arc shape can make the rubber block better contact the impact surface, thereby dispersing the impact force and reducing the direct damage to the clamping plate caused by the impact. In addition, the circular arc shape can also increase the elasticity and toughness of the rubber block, making it more durable when facing impacts and extending its service life.

[0011] Furthermore, the metal film layer is composed of metallic zinc; the surface of the battery cover is protected from corrosion by electroplating metallic zinc for waterproofing; electroplating zinc is a surface finishing method that forms a zinc layer on the metal surface by electrochemical deposition, which provides a cheap but efficient method to protect metal objects from corrosion. Electroplating zinc has the characteristics of good corrosion resistance, fine and uniform bonding, and is not easy for corrosive gases or liquids to enter the interior. Metallic zinc is used as the material of the metal film layer to effectively protect the surface of the battery cover for a long time and increase its service life. At the same time, the waterproof film layer at one end of the metal film layer is used to waterproof the metal film layer, reducing the exposure of the metal film layer to oxygen. When the waterproof film layer is damaged, the metal film layer protects the battery cover from corrosion.

[0012] Furthermore, the waterproof membrane layer is made of PP polypropylene; PP polypropylene is one of the lightest types of plastics, which makes it more convenient to transport and process. It has good tensile strength, rigidity and chemical stability. The surface of the polypropylene material can remain relatively dry and is not easy to absorb moisture. Even if the polypropylene material is soaked for a long time, it is not easy to absorb water and deform. The methyl alkyl, o-phthalic acid, hydrogen and other groups contained in its chemical structure are relatively stable and not easily affected by water.

[0013] In addition, polypropylene has a low water absorption rate, which is only 0.01% in water within 24 hours. The specific gravity of polypropylene is about 0.9g / cm³, which is lighter than water and is not easily absorbed and precipitated by water. At the same time, polypropylene has a tight molecular structure and a relatively low microporosity, making it less susceptible to water erosion. PP polypropylene is used as the waterproof material of the waterproof film layer 14 to further ensure the waterproof performance of the battery cover.

[0014] Furthermore, the surface of the cover body is provided with a limiting assembly for applying pressure to the battery surface, the limiting assembly includes a limiting pressure strip and a limiting pressure block, the limiting pressure strips are linearly arranged on the surface of the cover body, and the distance between two adjacent limiting pressure strips is equidistant;

[0015] The limiting strips can ensure that the force on the battery surface is evenly distributed when pressure is applied, thus avoiding battery damage or performance degradation caused by excessive local pressure. The uniform force distribution can effectively prevent thermal runaway or other safety hazards caused by uneven force on the battery, thus ensuring safety and stability during use. At the same time, the use of equidistant limiting strips can also improve the stability of the cover's fixation to the battery, ensuring that the battery will not loosen or shift due to vibration or other external factors during use.

[0016] Further, the limiting pressure blocks are arranged equidistantly on the surface of the limiting pressure strip, and the limiting pressure blocks are in the shape of arc protrusions; the arrangement of the limiting pressure blocks equidistantly on the surface of the limiting pressure strip helps to ensure that the pressure exerted by the limiting pressure blocks on the battery surface is evenly distributed, avoiding deformation or damage of the battery caused by excessive or too small local pressure. The arc protrusion shape of the limiting pressure block can better fit the contact surface of the battery, reducing the stress concentration phenomenon caused by shape mismatch, thereby improving the service life. Moreover, the arc protrusion shape can effectively disperse the pressure, reducing the pressure value per unit area, making the force more uniform, avoiding damage caused by uneven pressure, and at the same time improving the stability to prevent the battery from shifting or falling off under external forces such as vibration or impact in the battery compartment.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: adopting the structure in which one end of the metal film layer is connected with the waterproof film layer reduces the exposure of the metal film layer to oxygen. When the waterproof film layer is damaged, the metal film layer plays a role in protecting the battery cover from corrosion.

[0018] In addition, by installing a connection component in the installation groove, where the auxiliary cover body and the external battery compartment are magnetically paired and connected, the connection performance between the cover body and the external battery compartment is increased, improving the connection stability and installation effect between the two, avoiding the phenomenon that the cover body falls off from the battery compartment and causes the battery to drop outside, improving the traditional buckling method, reducing the loss generated during installation or disassembly. Through the magnetic attraction and manual pulling methods, the wear generated during connection is reduced, while improving the service life and increasing the installation efficiency.

Detailed implementation mode

[0025] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0026] In this embodiment, please refer to Figures 1-5 , a structure of a coated plate battery cover implemented specifically includes a cover body 1, a clamping plate 2, a clamping groove 3 and a clamping block 4. The clamping plate 2 is installed at one end of the cover body 1 and is in a convex shape. The clamping groove 3 is opened on the surface of the clamping plate 2 and is symmetrically arranged. The cover body 1 is a base layer 5. One end of the base layer 5 is electroplated with a metal film layer 6. One end of the metal film layer 6 is connected with a waterproof film layer 14. An installation groove 8 is opened inside the cover body 1, and a connection component for assisting the magnetic pairing connection between the cover body 1 and an external battery compartment is installed inside the installation groove 8.

[0027] The connection component includes a moving block 9 and a return spring 10. The two ends of the return spring 10 are respectively abutted against the moving block 9 and one end of the installation groove 8. The diameter of the return spring 10 is smaller than the diameter of the installation groove 8. The outer side surface of the moving block 9 can slide along the inner wall of the installation groove 8. The highest point of one end of the moving block 9 is lower than the surface of the installation groove 8. The two ends of the return spring 10 are respectively abutted against the moving block 9 and one end of the installation groove 8. This structure ensures that the elastic restoring force of the return spring 10 can effectively act on the moving block 9, enabling it to move quickly when needed. The diameter of the return spring 10 is smaller than the diameter of the installation groove 8. This design not only facilitates the installation and disassembly of the return spring 10 but also allows the return spring 10 to have appropriate movement space inside the installation groove 8, increasing its service life and reliability. The highest point of one end of the moving block 9 being lower than the surface of the installation groove 8 prevents the moving block 9 from colliding with the surface of the installation groove 8 during movement, thereby reducing noise and wear.

[0028] One end of the moving block 9 is a magnetic attraction block 11. The moving block 9 and the magnetic attraction block 11 are coaxially arranged. One end of the magnetic attraction block 11 extends beyond the inner wall of the installation groove 8. One end of the moving block 9 is connected with a dial 12 for assisting the return spring 10 to return. The return spring 10 is located on the outer side surface of the dial 12. One end of the dial 12 extends beyond the surface of the cover body 1. A magnetic attraction groove paired with the magnetic attraction block 11 can be opened inside the battery compartment. When the magnetic attraction block is connected to the magnetic attraction groove, the moving block 9 slides into the inside of the magnetic attraction groove under the influence of magnetic force, thereby playing a clamping role to prevent the surface of the cover body 1 from falling off the battery compartment. When manually pulling one end of the dial 12, the moving block 9 is driven by the dial 12 to move, making the magnetic attraction block 11 flush with the surface of one end of the cover body 1, facilitating the disassembly of the cover body 1 from the battery compartment.

[0029] The clamping block 4 is in a convex shape, made of rubber material. One end of the clamping block 4 is inclined. The clamping block 4 is installed on the surface of the cover body 1 and is a symmetrical structure. The convex shape and rubber material of the clamping block 4 endow it with excellent elasticity and grip. When the cover body 1 is connected to the battery compartment, it can ensure that the cover body 1 and the battery compartment are firmly installed and not easily fall off when the clamping block 4 is used. Its inclined end makes the insertion or removal smoother, reducing the operation difficulty. The advantage of this symmetrical structure is that the clamping block 4 can evenly distribute the force exerted by the cover body 1 on the battery compartment, enhancing the stability and durability of the overall structure, and at the same time improving the convenience and comfort of use.

[0030] One end of the clamping plate 2 is provided with a rubber block 13 for buffering impact force, and the rubber block 13 is in a circular arc convex shape. The advantage of the rubber block 13 being in a circular arc convex shape is that it can effectively buffer the impact force. When the clamping plate 2 is impacted, this circular arc shape can make the rubber block 13 better contact the impact surface, thereby dispersing the impact force and reducing the direct damage of the impact to the clamping plate 2. In addition, the circular arc shape can also increase the elasticity and toughness of the rubber block 13, making it more durable when facing impacts and extending its service life.

[0031] The metal film layer 6 is composed of metallic zinc. Electroplating metallic zinc is used to protect the surface of the waterproof protective battery cover from corrosion. Electrogalvanizing is a surface finishing method that forms a zinc layer on the metal surface through electrochemical deposition. It provides a cheap but efficient method to protect metal objects from corrosion. Electrogalvanizing has the characteristics of good corrosion resistance, fine and uniform combination, and is not easily penetrated by corrosive gases or liquids. Using metallic zinc as the material of the metal film layer 6 can effectively protect the surface of the battery cover for a long time, increasing its service life. At the same time, a waterproof film layer 14 at one end of the metal film layer 6 is used to provide waterproof protection for the metal film layer 6, reducing the exposure of the metal film layer 6 to oxygen. When the waterproof film layer 14 is damaged, the metal film layer 6 can play a role in protecting the battery cover from corrosion.

[0032] The waterproof film layer 14 is composed of PP polypropylene. PP polypropylene is one of the lightest varieties of plastics, which makes it more convenient in handling and processing. It has good tensile strength, rigidity and chemical stability. The surface of the polypropylene material can remain relatively dry and is not easy to absorb water. Even if the polypropylene material is soaked for a long time, it is not easy to absorb water and deform. The groups such as methyl alkyl, phthalic dimethyl, and hydrogen contained in its chemical structure are relatively stable and are not easily affected by water.

[0033] In addition, polypropylene has a low water absorption rate. Its water absorption rate in water for 24 hours is only 0.01%. The specific gravity of polypropylene is about 0.9 g / cm³, which is lighter than water and not easily absorbed or precipitated by water. At the same time, the molecular structure of polypropylene is compact and the microporosity is relatively low, making it even less susceptible to water erosion. Using PP polypropylene as the waterproof material for the waterproof film layer 14 further ensures the waterproof performance of the battery cover.

[0034] A limiting component for pressing the surface of the battery is provided on the surface of the cover body 1. The limiting component includes a limiting strip 15 and a limiting block 7. The limiting strips 15 are linearly arranged on the surface of the cover body 1, and the distance between adjacent limiting strips 15 is equally spaced.

[0035] The limiting strip 16 can ensure that when the surface of the battery is under pressure, the force distribution is uniform, avoiding battery damage or performance degradation caused by excessive local pressure. The uniform force distribution can effectively prevent thermal runaway or other safety hazards caused by uneven stress on the battery, ensuring the safety and stability during use. At the same time, the equally spaced limiting strips 16 can also improve the fixing stability of the cover body to the battery, ensuring that the battery will not loosen or shift due to vibration or other external factors during use.

[0036] The limiting blocks 7 are equally spaced on the surface of the limiting strip 15, and the limiting blocks 7 are in the shape of arc protrusions. With the arrangement of the limiting blocks 7 equally spaced on the surface of the limiting strip 15, this design helps to ensure that the pressure exerted by the limiting blocks 7 on the surface of the battery is evenly distributed, avoiding battery deformation or damage caused by excessive or too little local pressure. The arc protrusion shape of the limiting blocks 7 can better fit the contact surface of the battery, reducing the stress concentration phenomenon caused by shape mismatch, thereby improving the service life. Moreover, the arc protrusion shape can effectively disperse the pressure, reducing the pressure value per unit area, making the force more uniform, avoiding damage caused by uneven pressure, and at the same time improving the stability, preventing the battery from shifting or falling off under external forces such as vibration or impact in the battery compartment.

[0037] The operation process of the present utility model is as follows: Through manual installation, the battery cover and the battery compartment are paired and installed. A magnetic attraction groove for paired installation with the magnetic attraction block 11 can be opened inside the battery compartment. When the magnetic attraction block 11 is under pressure, the moving block 9 and the magnetic attraction block 11 are accommodated through the installation groove 8, making the surface of the magnetic attraction block 11 flush with the surface of the cover body 1, facilitating the installation of the battery cover and the battery compartment, and reducing the phenomenon that the magnetic attraction block 11 protrudes and hinders the installation. When the magnetic attraction block 11 is connected to the magnetic attraction groove, the moving block 9 slides into the interior of the magnetic attraction groove under the influence of magnetic force, thereby playing a clamping role to prevent the surface of the cover body 1 from falling off the battery compartment. When one end of the dial 12 is manually pulled, the moving block 9 is driven to move through the dial 12, making the magnetic attraction block 11 flush with the surface of one end of the cover body 1, facilitating the disassembly of the cover body 1 from the battery compartment.

[0038] When the cover body 1 is connected to the battery compartment, the clamping block 4 enables the cover body 1 and the battery compartment to be cooperatively connected by means of buckling. Its inclined surface increases the characteristics of firm installation and not being easily detached, and the inclined end thereof makes it smoother when inserting or removing, reducing the operation difficulty. Since rubber material is adopted, the friction and loss between material rigidities during cooperative installation are reduced.

[0039] The design key point of the present utility model lies in: adopting a structure in which one end of the metal film layer 6 is connected with the waterproof film layer 14, reducing the exposure of the metal film layer 6 to oxygen. When the waterproof film layer 14 is damaged, the metal film layer 6 plays a role in protecting the battery cover from corrosion;

[0040] In addition, by installing a connection component in the installation groove 8 that magnetically pairs the cover body 1 with the external battery compartment, the connection performance between the cover body 1 and the external battery compartment is increased, the connection stability and installation effect between the two are improved, and the phenomenon that the cover body 1 falls off from the battery compartment and causes the battery to fall outside is avoided. By means of magnetic attraction and manual pulling, the wear generated during connection is reduced, the service life is increased, and the installation efficiency is improved at the same time.

[0041] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as the protection scope of the present utility model.
