Description

Technical Field

[0001] The utility model relates to the technical field of flat-plate intelligent electronic products, in particular to an electronic product frame structure and a flat-plate electronic product. Background Art

[0002] The control requirements of the EU Battery Regulation (EU) 2023 / 1542, which came into effect on February 18, 2024, cover the entire life cycle of batteries, including production, reuse, and recycling. 42 months after the implementation of the regulation, portable batteries must be removable and replaceable for end users. However, the batteries of large-screen mobile phones and tablet computers currently on the market are not removable or replaceable for end users. In order to comply with product regulations, it is necessary to re-examine the structural design of the products and make corresponding adjustments to the product structure in accordance with the EU Battery Regulation. Since large-screen mobile phones and tablet computers have higher battery capacity requirements, the ultra-thin design of such electronic products makes the battery area larger. Therefore, in the design of the removable battery structure, special consideration needs to be given to the fixation of large-area batteries.

[0003] The traditional battery detachable design in the industry is to set push-pull grooves on the product frame to achieve the sliding installation of push-pull cover plates, or set clips on the product frame to achieve the installation of clip-on cover plates, so as to facilitate the removal and assembly of batteries. However, in the above designs, both push-pull grooves and clips are set at the edge where the cover plate and the product frame meet, which makes it difficult to take into account the fixation of the middle part of the battery. As a result, the structural strength of the battery and the product frame is insufficient, and the battery is easy to loosen in the product frame, which in turn affects the normal use and power supply of electronic products. Although using a large number of screws to fix the cover plate can improve the stability of battery installation, it will also affect the appearance of the product. At the same time, the product assembly workload is large, making the product disassembly and assembly efficiency insufficient. Utility Model Content

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Please combine Figure 1-8The present 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 product's screen module, the back plate 400 is the product's back cover, the battery frame 500 is used to support and clamp the battery, and the main frame 100 and the back cover frame 300 are used to provide support for the rest of the product. The main frame 100 with 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 surface of the main frame 100 is the surface that cooperates with the panel 200, the back side of the main frame 100 is the side of the main frame 100 that is away from the panel 200, the back side of the main frame 100 is the side of the main frame 100 that is away from the panel 200, the main surface of the back cover frame 300 is the side of the back cover frame 300 that cooperates with the main frame 100, and the back side of the back cover frame 300 is the side of the back cover frame 300 that is away from the main frame 100. The relevant orientation restrictions in the following text can refer to this explanation.

[0029] The main frame 100 includes a first frame 110 having a rectangular ring structure, a first separator 120 housed within the inner space of the first frame 110 and fixedly connected to the first frame 110 to divide the inner space of the first frame 110 into a battery installation area 111 and a motherboard installation area 112, and at least one second separator 130 housed within the battery installation area 111 and fixedly connected to the first frame 110 and the first separator 120. A plurality of oblique holes 140 are respectively formed on the first frame 110, the first separator 120, and the second separator 130. The battery installation area 111 is used to accommodate batteries, and the motherboard installation area 112 is used to accommodate the product motherboard and its related functional components. In this embodiment, the first separator 120 extends along the width direction of the first frame 110, and the second separator 130 extends along the length direction of the first frame 110. The back cover frame 300 includes a second frame 310 with a rectangular ring structure and adhered to the back of the first frame 110, a third dividing strip 320 corresponding to the back of the first dividing strip 120 and fixedly connected to the second frame 310, and at least one fourth dividing strip 330 corresponding to the back of the second dividing strip 130 and fixedly connected to the second frame 310 and the third dividing strip 320. The main surface of the second frame 310, the main surface of the third dividing strip 320 and the main surface of the fourth dividing strip 330 are respectively provided with a plurality of inclined guide columns 340, the inner contour shape of the inclined hole 140 is adapted to the outer contour shape of the inclined guide column 340, and each inclined guide column 340 is slidably inserted into each inclined hole 140 one by one, 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 fixedly connected to the first frame 110 and the second separator 130. The battery frame 500 is mounted on the back of the main frame 100 and has mounting locations for receiving batteries. Once the battery frame 500 is mounted on the main frame 100, it is clamped by the main frame 100 and the rear cover frame 300, securing the battery frame 500 and the batteries mounted thereon.

[0030] It can be understood that the contour shape of the back cover frame 300 is adapted to the contour shape of the main frame 100, so that when the back cover frame 300 is assembled with the main frame 100, the main surface of the back cover frame 300 can fully fit the back surface of the main frame 100, thereby increasing the mating area between the back cover frame 300 and the main frame 100, improving the stability of the connection between the two and the structural strength of the electronic product frame structure. By providing 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 is mated with the main frame 100, the back cover frame 300 is tilted and inserted into the inclined holes 140 along the diagonal direction. While achieving positional limitation between the back cover frame 300 and the main frame 100 along the plane of the main surface of the panel 200, the back cover frame 300 and the main frame 100 are also limited along the thickness direction of the panel 200, thereby preventing the back cover frame 300 and the back panel 400 from falling off from the main frame 100. By screwing the second frame 310 to the first frame 110, on the one hand, it is to meet the appearance requirements of the current electronic product frame structure on the market (the back of the current electronic product frame structure is installed with a few screws) and to 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 back cover frame 300, so as to prevent the inclined guide column 340 on the back cover frame 300 from sliding out of the inclined hole 140 due to improper operation during use of the product.

[0031] In one embodiment, a plurality of inclined holes 140 are uniformly provided on the first frame 110, a plurality of inclined holes 140 are uniformly provided on the first dividing bar 120, and a plurality of inclined holes 140 are uniformly provided on the second dividing bar 130, for a total of 25 inclined holes 140 are provided on the main frame 100. Accordingly, a plurality of inclined guide posts 340 are uniformly provided on the main surface of the second frame 310, a plurality of inclined guide posts 340 are uniformly provided on the main surface of the third dividing bar 320, and a plurality of inclined guide posts 340 are uniformly provided on the main surface of the fourth dividing bar 330, for a total of 25 inclined guide posts 340 corresponding to each inclined hole 140 on the back cover frame 300. This increases the limiting engagement area between the main frame 100 and the back cover frame 300, and improves the stability of the connection between the two. In other embodiments, the number of inclined holes 140 and inclined guide posts 340 can be further adjusted according to the size of the electronic product frame structure, which will not be further described 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 a closed figure with an outer contour formed by curves. Preferably, the cross-section of the inclined guide column 340 is a diamond structure, and a first arc-shaped transition surface is provided at each edge of the diamond structure. Correspondingly, the inclined hole 140 is a diamond hole extending along the inclined path, and the corner portion of the diamond hole is provided with a second arc-shaped transition surface that slides with the first arc-shaped transition surface. In this way, while the sliding path of the inclined guide column 340 is limited by the inclined hole 140, the scratches on the inclined guide column 340 when inserted into the inclined hole 140 can be reduced, thereby avoiding the relative shaking problem between the main frame 100 and the back cover frame 300 caused by the wear of the inclined guide column 340, and improving the stability of the connection between the main frame 100 and the back 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, and the N second separators 130 divide the battery installation area 111 to form N+1 sub-areas arranged side by side. In this embodiment, the number of second separators 130 is 1, and the second separator 130 divides the battery installation area 111 to form two sub-areas 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 may be arranged side by side in the battery installation area 111, and each second separator 130 is parallel to each other to divide the battery installation area 111 into multiple sub-areas. Correspondingly, the number of fourth separators 330 is the same as the number of second separators 130, and the positions of the two correspond one to one. In this way, the number of second separators 130 and fourth separators 330 is adjusted according to the size of the battery to achieve the definition of multiple areas in the middle of the battery, thereby improving the reliability of battery positioning.

[0034] Furthermore, the battery frame 500 includes N+1 sub-frames 510 arranged side by side and correspondingly accommodated in their respective areas. Two adjacent sub-frames 510 are fixedly connected by at least one first connecting bar 520. At least one second connecting bar 530 and at least one third connecting bar 540 are provided on the side of the outermost sub-frame 510 facing away from the first connecting bar 520. The first frame 110 is provided with a plurality of first limiting grooves 113 and a pair of first limiting grooves 113 for respectively embedding the second connecting bars 530. A plurality of second limiting grooves 114 for embedding each third connecting bar 540 are provided on the second frame 310, a plurality of third limiting grooves 311 for embedding each second connecting bar 530 correspondingly and a plurality of fourth limiting grooves 312 for embedding each third connecting bar 540 correspondingly, the second dividing bar 130 is provided with at least one fifth limiting groove 131 for correspondingly embedding each first connecting bar 520, and the fourth dividing bar 330 is provided with at least one sixth limiting groove 331 for correspondingly embedding each first connecting bar 520. 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 bar 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 bar 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 bar 520. In this way, the battery frame 500 is limited by the common constraints of the connecting bars on the battery frame 500 by the limiting grooves on the main frame 100 and the back cover frame 300, so as to prevent the battery frame 500 from shaking between the main frame 100 and the back cover frame 300, thereby improving the reliability of the limitation of the battery frame 500. Preferably, in this embodiment, two adjacent sub-frames 510 are fixedly connected by a plurality of first connecting bars 520 arranged side by side, and a connection channel 550 is formed between the two adjacent first connecting bars 520, which is connected to an inclined hole 140 and for the inclined guide column 340 to pass through; a plurality of second connecting bars 530 and a plurality of third connecting bars 540 are provided on the side of the outermost sub-frame 510 facing away from the first connecting bar 520, thereby increasing the matching area between the battery frame 500 and the main frame 100 and the back cover frame 300, and further improving the stability of the battery frame 500 limit.

[0035] Furthermore, in this embodiment, the third connecting bar 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, thereby preventing damage to the battery and the battery frame 500 due to the battery frame 500 falling off the main frame 100 after the rear cover frame 300 is removed from the main frame 100. In addition, a plurality of annularly arranged inclined baffles 511 are provided at the outer edge of each sub-frame 510 adjacent to the rear cover frame 300. The inclined baffles 511 collectively form a battery limiting area. Specifically, the end of each inclined baffle 511 facing away from the sub-frame 510 is bent away from the center of the sub-frame 510, and the entire battery limiting area has a flared structure. The inclined baffles 511 can limit the edge of the battery to prevent the battery from shifting on the battery frame 500. The inner edge of each sub-frame 510 protrudes toward the center of the sub-frame 510 to form a mounting position 512 . The mounting position 512 is used to receive a battery to limit the position of 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 fasteners, or the panel 200 is adhered to the main surface of the main frame 100 by glue. The back panel 400 is adhered to the back of the rear cover frame 300. Preferably, the back panel 400 is adhered to the back of the rear cover frame 300 by strong glue. In addition, in this embodiment, each of the four corners of the second frame 310 is fixedly connected to the corresponding portion of the first frame 110 by a screw 350. Accordingly, through holes 410 are provided on the back panel 400 at the corresponding screw connection portions between the second frame 310 and the first frame 110, that is, four through holes 410 are provided on the back panel 400. The through holes 410 are covered with rubber pads to hide and encapsulate the screws 350 to prevent the screws 350 from affecting the appearance of the product.

[0037] In this embodiment, the back cover frame 300 can be manufactured using a variety of alternative methods. In one embodiment, the back cover frame 300 is manufactured by machining a single piece of sheet metal. Specifically, a single piece of aluminum alloy sheet metal is machined to define the outline of each inclined guide post 340. The angle of each inclined guide post 340 is then cut using wire cutting, and the remaining features of the back cover frame 300 are then machined. While this method yields a strong back cover frame 300, it also results in significant material waste and high processing costs. In another embodiment, the inclined guide posts 340 are welded to the main body of the back cover frame 300. Specifically, the back cover frame 300 is machined to the same profile as the main frame 100, and the inclined guide posts 340 are machined separately. A specialized welding fixture is then designed, and each inclined guide post 340 on the back cover frame 300 is welded to the fixture. After welding, the surface is polished to produce the finished back cover frame 300. This method saves material and provides a strong product structure, but it involves numerous steps and is complex. In another embodiment, the rear cover frame 300 is manufactured by using a mold by adopting powder metallurgy or injection molding.

[0038] When assembling the product, if it is assembled in a factory, the main frame 100 and the back cover frame 300 are fixed on a special jig by vacuum adsorption respectively, and automatic alignment is performed by a visual system as an auxiliary assembly measure to achieve high-precision assembly of the back cover frame 300 and the main frame 100. After assembly, screws are tightened on the four corners of the back cover frame 300, and the panel 200 and the back panel 400 are fixed on the main frame 100 and the back cover frame 300 respectively. For end-consumer assembly, due to the large size and thin thickness of the product, the back cover frame 300 will bend and deform under the action of gravity, making it difficult to align multiple inclined guide columns 340 with the inclined holes 140 at the same time. Therefore, after fixing the panel 200 and the back panel 400 on the main frame 100 and the back cover frame 300 respectively, it is necessary to fix the back cover frame 300 on a plane with good flatness (such as a glass plate, etc.), hold the main frame 100, align the inclined holes 140 one by one with the inclined guide columns 340, and then slowly push until the main frame 100 and the back cover frame 300 are snapped into place, and then fixed with screws. Finally, put rubber pads on the screw heads to hide the screws.

[0039] The present invention also discloses a flat-panel electronic product comprising the aforementioned electronic product frame structure, a battery mounted on a battery frame 500, and a motherboard housed within a motherboard mounting area 112 and fixedly connected to the first frame 110, the second frame 310, the first separator 120, and the third separator 320. The flat-panel electronic product can be a large-screen mobile phone or tablet computer. By incorporating the aforementioned electronic product frame structure into the flat-panel electronic product, the battery can be removed and replaced without changing the product's current appearance, while also improving the stability of the battery installation.

[0040] In the electronic product frame structure and the flat electronic product of the present invention, the battery installation area 111 is separated by the second partition bar 130, and an inclined hole 140 is provided on the first frame 110, the first partition bar 120 and the second partition bar 130, and an inclined guide column 340 is provided on the second frame 310, the third partition bar 320 and the fourth partition bar 330. The inclined guide column 340 is matched with the inclined hole 140 to realize the internal multi-point buckling constraint between the main frame 100 and the back cover frame 300, thereby ensuring the back cover frame 300 and the main frame. The frames 100 can effectively constrain the batteries at the edges and in the middle, thereby improving the stability of battery installation. After assembling the back cover frame 300 and the main frame 100 with a few screws, the stable assembly of the electronic product frame structure is completed, thereby improving the assembly efficiency of the product. When disassembling, only a few screws need to be removed and the main frame 100 and the back cover frame 300 need to be relatively slid. The operation is simple, thereby improving the disassembly efficiency of the product. The fastening part between the main frame 100 and the back cover frame 300 is located inside the product, which has no effect on the appearance of the product and is conducive to improving the market competitiveness of the product.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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 above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
