Description

Technical Field

[0001] This invention relates to the field of flat-panel smart electronic products, and in particular to an electronic product frame structure and a flat-panel electronic product. Background Technology

[0002] The EU Battery Regulation (EU) 2023 / 1542, which came into effect on February 18, 2024, covers the entire lifecycle of batteries, including production, reuse, and recycling. Forty-two months after its implementation, the regulation requires that portable batteries be removable and replaceable for end users. However, currently, the batteries in large-screen smartphones and tablets on the market are not removable or replaceable for end users. To achieve product compliance, it is necessary to re-examine the product's structural design and make corresponding adjustments to the product structure to comply with the EU Battery Regulation. Because large-screen smartphones and tablets require higher battery capacity, the ultra-thin design of these electronic products results in a larger battery area. Therefore, in the design of a removable battery structure, special consideration must be given to securing this large battery area.

[0003] Traditional battery removable designs in the industry utilize either sliding grooves in the product frame for a sliding cover or snap-on clips for a snap-on cover to facilitate battery installation and removal. However, in both designs, the grooves and clips are located at the edges where the cover meets the frame, making it difficult to secure the battery in the center. This results in insufficient structural strength between the battery and the frame, making the battery prone to loosening and affecting the normal operation and power supply of the electronic product. While using numerous screws to secure the cover can improve battery installation stability, it also affects the product's appearance and increases the workload of assembly, leading to inefficient disassembly and reassembly. Summary of the Invention

[0004] Therefore, it is necessary to address the above-mentioned shortcomings by providing an electronic product frame structure and a flat electronic product that enables stable battery installation and quick disassembly without affecting the product's appearance.

[0005] An electronic product frame structure includes a main frame, a panel fixedly connected to the main surface of the main frame, a rear cover frame located on the back side of the main frame and detachably connected to the main frame, a back plate fixedly connected to the back of the rear cover frame, and a battery frame fixed on the main frame.

[0006] The main frame includes a first frame in a rectangular ring structure, a first partition strip that is housed in the ring space of the first frame and fixedly connected to the first frame to divide the ring space of the first frame into a battery mounting area and a motherboard mounting area, and at least one second partition strip that is housed in the battery mounting area and fixedly connected to the first frame and the first partition strip. The first frame, the first partition strip and the second partition strip are respectively provided with a plurality of oblique holes.

[0007] The rear cover frame includes a second frame with a rectangular ring structure that fits against the back of the first frame, a third partition that fits against the back of the first partition and is fixedly connected to the second frame, and at least one fourth partition that fits against the back of the second partition and is fixedly connected to the second frame and the third partition. The main surface of the second frame, the main surface of the third partition, and the main surface of the fourth partition are respectively provided with a plurality of inclined guide posts. The inner contour shape of the inclined hole is adapted to the outer contour shape of the inclined guide post. Each of the inclined guide posts is slidably inserted into the inclined hole in a corresponding manner, and the second frame is screwed to the first frame.

[0008] The battery frame is housed within the battery mounting area and is fixedly connected to the first frame and the second partition strip. The battery frame is mounted on the back of the main frame and has mounting positions for receiving batteries.

[0009] In one embodiment, the angle between the axis of the inclined guide post and the main surface of the rear cover frame is 30-60°.

[0010] In one embodiment, the angle between the axis of the inclined guide post and the main surface of the rear cover frame is 45°.

[0011] In one embodiment, the cross-section of the inclined guide post is a rhomboid structure.

[0012] In one embodiment, the number of second separators is N, where N is an integer greater than or equal to 1, and the N second separators divide the battery mounting area to form N+1 sub-regions arranged side by side.

[0013] In one embodiment, the battery frame includes N+1 sub-frames arranged side-by-side and spaced apart, each corresponding to a specific area within its respective region. Adjacent sub-frames are fixedly connected by at least one first connecting strip. The outermost sub-frame has at least one second connecting strip and at least one third connecting strip on its side facing away from the first connecting strip. The first frame has a plurality of first limiting slots corresponding to each second connecting strip and a plurality of second limiting slots corresponding to each third connecting strip. The second frame has a plurality of third limiting slots corresponding to each second connecting strip and a plurality of fourth limiting slots corresponding to each third connecting strip. The second dividing strip has at least one fifth limiting slot for corresponding to each first connecting strip, and the fourth dividing strip has at least one sixth limiting slot for corresponding to each first connecting strip.

[0014] In one embodiment, the third connecting strip is embedded in the second limiting groove and connected to the first frame screw.

[0015] In one embodiment, each subframe has a plurality of inclined baffles arranged in a ring at the outer edge of the side adjacent to the rear cover frame, and the inclined baffles together form a battery limiting area; the inner edge of each subframe protrudes towards the center of the subframe to form the mounting position.

[0016] In one embodiment, the back plate is attached to the back of the rear cover frame; the back plate has a through hole at the screw connection between the second frame and the first frame, and the through hole is covered with a rubber gasket.

[0017] The present invention also discloses a flat electronic product, which includes the above-described electronic product frame structure.

[0018] The electronic product frame structure and flat electronic product of this invention are divided into battery mounting areas by a second partition strip. Angled holes are provided on the first frame, the first partition strip, and the second partition strip. Inclined guide posts are provided on the second frame, the third partition strip, and the fourth partition strip. Through the limiting cooperation between the inclined guide posts and the angled holes, multi-point fastening constraints are achieved between the main frame and the rear cover frame, ensuring effective constraint of the battery at both the edges and the middle of the rear cover frame and the main frame, thus improving the stability of battery installation. The electronic product frame structure is stably assembled by using only a few screws to assemble the rear cover frame and the main frame, improving assembly efficiency. Disassembly only requires removing a few screws and sliding the main frame and the rear cover frame relative to each other, simplifying the operation and improving disassembly efficiency. The fastening points between the main frame and the rear cover frame are located inside the product, having no impact on the product's appearance, which helps enhance the product's market competitiveness.

[0027] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Please combine Figure 1-8This invention discloses an electronic product frame structure suitable for tablet computers and large-screen mobile phones. Specifically, the electronic product frame structure includes a main frame 100, a panel 200 fixedly connected to the main surface of the main frame 100, a back cover frame 300 located on the back side of the main frame 100 and detachably connected to the main frame 100, a back plate 400 fixedly connected to the back of the back cover frame 300, and a battery frame 500 fixed to the main frame 100. It should be noted that in this embodiment, the panel 200 is the screen module of the product, the back plate 400 is the back cover of the product, the battery frame 500 is used to support and hold the battery, and the main frame 100 and the back cover frame 300 provide support for the rest of the product. The main frame 100, which houses the battery frame 500, is fixedly connected to the panel 200 to form the first part of the electronic product frame structure, and the back cover frame 300 is fixedly connected to the back plate 400 to form the second part of the electronic product frame structure. The assembly and disassembly of the electronic product frame structure is the assembly and disassembly of the first and second parts. The main side of the main frame 100 is the side that mates with the panel 200. The back side of the main frame 100 is the side of the main frame 100 that faces away from the panel 200. The back side of the main frame 100 is the side of the main frame 100 that faces away from the panel 200. The main side of the rear cover frame 300 is the side of the rear cover frame 300 that mates with the main frame 100. The back side of the rear cover frame 300 is the side of the rear cover frame 300 that faces away from the main frame 100. The directional limitations mentioned later can be referred to this explanation.

[0029] The main frame 100 includes a first frame 110 with a rectangular ring structure, a first partition strip 120 housed within the ring space of the first frame 110 and fixedly connected to the first frame 110 to divide the ring space of the first frame 110 into a battery mounting area 111 and a motherboard mounting area 112, and at least one second partition strip 130 housed within the battery mounting area 111 and fixedly connected to the first frame 110 and the first partition strip 120. The first frame 110, the first partition strip 120, and the second partition strip 130 are each provided with a plurality of oblique holes 140. The battery mounting area 111 is used to house the battery, and the motherboard mounting area 112 is used to house the product motherboard and its related functional components. In this embodiment, the first partition strip 120 extends along the width direction of the first frame 110, and the second partition strip 130 extends along the length direction of the first frame 110. The rear cover frame 300 includes a second frame 310 with a rectangular ring structure that fits against the back of the first frame 110, a third partition 320 that fits against the back of the first partition 120 and is fixedly connected to the second frame 310, and at least one fourth partition 330 that fits against the back of the second partition 130 and is fixedly connected to the second frame 310 and the third partition 320. The main surfaces of the second frame 310, the third partition 320, and the fourth partition 330 are respectively provided with a plurality of inclined guide posts 340. The inner contour shape of the inclined hole 140 is adapted to the outer contour shape of the inclined guide post 340. Each inclined guide post 340 is slidably inserted into each inclined hole 140 in a corresponding manner, and the second frame 310 is screwed to the first frame 110. The battery frame 500 is housed within the battery mounting area 111 and is fixedly connected to the first frame 110 and the second partition strip 130. The battery frame 500 is mounted on the back of the main frame 100, and has mounting positions for receiving batteries. Thus, after the battery frame 500 is mounted on the main frame 100, it is actually clamped by the main frame 100 and the rear cover frame 300, thereby fixing the battery frame 500 and the batteries mounted on it.

[0030] This can be understood as the contour shape of the back cover frame 300 conforming to the contour shape of the main frame 100. This allows the main surface of the back cover frame 300 to fully fit against the back of the main frame 100 during assembly, increasing the mating area between the two and improving the stability of their connection and the structural strength of the electronic product's frame structure. By setting inclined guide posts 340 at various locations on the back cover frame 300 and opening inclined holes 140 at various locations on the main frame 100, when the back cover frame 300 mates with the main frame 100, the back cover frame 300 is inserted obliquely into the inclined holes 140 along the inclined line direction. This not only limits the positioning of the back cover frame 300 and the main frame 100 along the plane of the main surface of the panel 200, but also limits their positioning along the thickness direction of the panel 200, preventing the back cover frame 300 and the back plate 400 from detaching from the main frame 100. By connecting the second frame 310 to the first frame 110 with screws, on the one hand, it is to meet the appearance requirements of the current electronic product frame structure (the back of the current electronic product frame structure is equipped with a few screws) and minimize or even eliminate the impact on the appearance of the current electronic product frame structure. On the other hand, the screw connection between the second frame 310 and the first frame 110 further improves the stability of the connection between the main frame 100 and the rear cover frame 300, so as to prevent the inclined guide post 340 on the rear cover frame 300 from sliding out of the inclined hole 140 due to improper operation during product use.

[0031] In one embodiment, a plurality of oblique holes 140 are evenly distributed on the first frame 110, the first partition strip 120, and the second partition strip 130, resulting in a total of 25 oblique holes 140 on the main frame 100. Correspondingly, a plurality of inclined guide posts 340 are evenly distributed on the main surface of the second frame 310, the third partition strip 320, and the fourth partition strip 330, resulting in a total of 25 inclined guide posts 340 corresponding to each oblique hole 140 on the rear cover frame 300. This increases the limiting and fastening area between the main frame 100 and the rear cover frame 300, improving the stability of their connection. In other embodiments, the number of oblique holes 140 and inclined guide posts 340 can be further adjusted according to the dimensions of the electronic product frame structure, which will not be elaborated here.

[0032] In one embodiment, the angle between the axis of the inclined guide post 340 and the main surface of the rear cover frame 300 is 30-60°. Preferably, the angle between the axis of the inclined guide post 340 and the main surface of the rear cover frame 300 is 45°. The cross-section of the inclined guide post 340 can be a polygonal structure with more than three sides, or it can be a closed shape whose outer contour is formed by curves. Preferably, the cross-section of the inclined guide post 340 is a rhomboid structure, and each edge of the rhomboid structure is provided with a first arc-shaped transition surface. Correspondingly, the inclined hole 140 is a rhomboid hole extending along the inclined path. The corner part of the rhomboid hole is provided with a second arc-shaped transition surface that slides and engages with the first arc-shaped transition surface. In this way, while limiting the sliding path of the inclined guide post 340 through the inclined hole 140, the scratches suffered by the inclined guide post 340 when inserted into the inclined hole 140 can be reduced, and the relative shaking problem between the main frame 100 and the rear cover frame 300 caused by the wear of the inclined guide post 340 can be avoided, thereby improving the stability of the connection between the main frame 100 and the rear cover frame 300.

[0033] In one embodiment, the number of second separators 130 is N, where N is an integer greater than or equal to 1. N second separators 130 divide the battery mounting area 111 to form N+1 sub-regions arranged side-by-side. In this embodiment, the number of second separators 130 is 1, and the second separator 130 divides the battery mounting area 111 to form two sub-regions arranged side-by-side. In other embodiments, depending on the size of the battery to be installed, two, three, or even more second separators 130 can be arranged side-by-side at intervals within the battery mounting area 111, with each second separator 130 parallel to each other, to divide the battery mounting area 111 into multiple sub-regions. Correspondingly, the number of fourth separators 330 is the same as the number of second separators 130, and their positions correspond one-to-one. Thus, by adjusting the number of second separators 130 and fourth separators 330 according to the battery size, multiple regions in the middle of the battery can be defined, thereby improving the reliability of battery positioning.

[0034] Furthermore, the battery frame 500 includes N+1 sub-frames 510 arranged side-by-side and spaced apart, each corresponding to a specific area within its respective region. Adjacent sub-frames 510 are fixedly connected by at least one first connecting strip 520. The outermost sub-frame 510 has at least one second connecting strip 530 and at least one third connecting strip 540 on its side facing away from the first connecting strip 520. The first frame 110 has multiple first limiting grooves 113 corresponding to and fitted with each second connecting strip 530, and a pair of... The second frame 310 has a plurality of second limiting grooves 114 for each third connecting strip 540 to be embedded, and a plurality of third limiting grooves 311 and a plurality of fourth limiting grooves 312 for each third connecting strip 540 to be embedded. The second dividing strip 130 has at least one fifth limiting groove 131 for each first connecting strip 520 to be embedded, and the fourth dividing strip 330 has at least one sixth limiting groove 331 for each first connecting strip 520 to be embedded. In this embodiment, the sum of the depths of the first limiting groove 113 and the third limiting groove 311 is equal to the thickness of the second connecting strip 530, the sum of the depths of the second limiting groove 114 and the fourth limiting groove 312 is equal to the thickness of the third connecting strip 540, and the sum of the depths of the fifth limiting groove 131 and the sixth limiting groove 331 is equal to the thickness of the first connecting strip 520. Thus, by the joint constraint of the connecting strips on the battery frame 500 by the limiting grooves on the main frame 100 and the rear cover frame 300, the battery frame 500 is limited, preventing the battery frame 500 from shaking between the main frame 100 and the rear cover frame 300, thereby improving the reliability of the battery frame 500's limitation. Preferably, in this embodiment, two adjacent sub-frames 510 are fixedly connected by a plurality of first connecting strips 520 arranged side by side, and a through channel 550 is formed between two adjacent first connecting strips 520, which communicates with an oblique hole 140 and allows the inclined guide post 340 to pass through; a plurality of second connecting strips 530 and a plurality of third connecting strips 540 are provided on the side of the outermost sub-frame 510 facing away from the first connecting strips 520, thereby increasing the mating area between the battery frame 500 and the main frame 100 and the rear cover frame 300, and further improving the stability of the battery frame 500 in the limiting position.

[0035] Furthermore, in this embodiment, the third connecting strip 540 is embedded in the second limiting groove 114 and screwed to the first frame 110. This improves the stability of the connection between the battery frame 500 and the main frame 100, thus preventing damage to the battery and battery frame 500 caused by the battery frame 500 detaching from the main frame 100 after the rear cover frame 300 is removed. In addition, each sub-frame 510 has a plurality of inclined baffles 511 arranged in a ring at the outer edge of the side adjacent to the rear cover frame 300. The inclined baffles 511 together form a battery limiting area. Specifically, the end of each inclined baffle 511 facing away from the sub-frame 510 is folded away from the center of the sub-frame 510, and the entire battery limiting area has an flared structure. Each inclined baffle 511 can limit the edge of the battery to prevent the battery from shifting on the battery frame 500. The inner edge of each subframe 510 protrudes towards the center of the subframe 510 to form a mounting position 512, which is used to receive the battery to limit the battery along the thickness direction of the battery frame 500.

[0036] In one embodiment, the panel 200 is fixed to the main surface of the main frame 100 by snap-fit, or the panel 200 is glued to the main surface of the main frame 100. The back panel 400 is attached to the back of the rear cover frame 300, preferably, the back panel 400 is attached to the back of the rear cover frame 300 by strong adhesive. In addition, in this embodiment, each of the four corners of the second frame 310 is fixedly connected to the corresponding part on the first frame 110 by a screw 350. Correspondingly, the back panel 400 has through holes 410 at the screw connection points between the second frame 310 and the first frame 110, that is, the back panel 400 has four through holes 410. The through holes 410 are covered with rubber gaskets, which are used to hide and seal the screws 350 to avoid the screws 350 affecting the appearance of the product.

[0037] In this solution, the rear cover frame 300 can be prepared by various alternative methods. In one embodiment, the rear cover frame 300 is obtained by processing a single piece of metal sheet. Specifically, the entire aluminum alloy sheet is cut, leaving the outline of each inclined guide post 340. Then, the included angle of each inclined guide post 340 is cut by wire cutting, and other features of the rear cover frame 300 are processed. The rear cover frame 300 processed by this method has good strength, but there is a lot of material waste and the processing cost is high. In another embodiment, the inclined guide posts 340 are set on the main body of the rear cover frame 300 by welding. Specifically, the rear cover frame 300 is processed into the same outline shape as the main frame 100, and the inclined guide posts 340 are processed separately. By designing a special welding positioning fixture, each inclined guide post 340 on the rear cover frame 300 is welded one by one on the welding positioning fixture. After welding, the surface is polished to obtain the finished rear cover frame 300. This solution saves materials and the product has high structural strength, but there are more processes and the operation is complicated. In another embodiment, the back cover frame 300 is obtained by using powder metallurgy or injection molding through a mold.

[0038] During product assembly, if assembly is carried out in the factory, the main frame 100 and the rear cover frame 300 are fixed to a special fixture by vacuum adsorption. The vision system automatically aligns the components as an assembly aid to achieve high-precision assembly of the rear cover frame 300 and the main frame 100. After assembly, screws are screwed on the four corners of the rear cover frame 300, and the panel 200 and the back plate 400 are fixed on the main frame 100 and the rear cover frame 300, respectively. For end-consumer assembly, due to the large size and thinness of the product, the back cover frame 300 will bend and deform under gravity, making it difficult to align multiple inclined guide posts 340 with the inclined holes 140 simultaneously. Therefore, after fixing the panel 200 and the back panel 400 to the main frame 100 and the back cover frame 300 respectively, the back cover frame 300 needs to be fixed on a flat surface with good flatness (such as a glass plate). Holding the main frame 100, align the inclined holes 140 with the inclined guide posts 340 one by one, and slowly push it in until the main frame 100 and the back cover frame 300 are engaged. Then, fix it with screws, and finally attach rubber pads to the screw heads to hide the screws.

[0039] In addition, this invention also discloses a flat electronic product, which includes the aforementioned electronic product frame structure, a battery mounted on a battery frame 500, and a motherboard housed in a motherboard mounting area 112 and fixedly connected to a first frame 110, a second frame 310, a first partition 120, and a third partition 320. This flat electronic product can be a large-screen mobile phone or a tablet computer. By incorporating the aforementioned electronic product frame structure into the flat electronic product, the battery is made removable and replaceable without altering the product's current appearance, while also improving the stability of battery installation.

[0040] The electronic product frame structure and flat electronic product of the present invention are implemented by dividing the battery mounting area 111 by a second partition 130. Inclined holes 140 are provided on the first frame 110, the first partition 120, and the second partition 130. Inclined guide posts 340 are provided on the second frame 310, the third partition 320, and the fourth partition 330. Through the limiting cooperation between the inclined guide posts 340 and the inclined holes 140, multi-point fastening constraints are achieved between the main frame 100 and the rear cover frame 300, ensuring the connection between the rear cover frame 300 and the main frame. The main frame 100 and the back cover frame 300 can effectively constrain the battery at both the edges and the middle, improving the stability of battery installation. After assembling the back cover frame 300 and the main cover frame 300 with a few screws, the stable assembly of the electronic product frame structure is completed, improving the product assembly efficiency. During disassembly, only a few screws need to be removed and the main cover frame 100 and the back cover frame 300 are slid relative to each other, making the operation simple and improving the product disassembly efficiency. The fastening part of the main cover frame 100 and the back cover frame 300 is located inside the product, which has no impact on the product appearance and helps to enhance the product's market competitiveness.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
