Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to an electronic device. Background Technology

[0002] With the rapid development of electronic device technology, battery capacity has become an important parameter for measuring the performance of electronic devices. In terms of increasing battery capacity, this can be achieved by reducing the space occupied by other components inside the electronic device, such as reducing the size of the motherboard and sub-boards, thereby providing more installation space for the battery and allowing for the installation of larger batteries inside the electronic device.

[0003] In related technologies, electronic devices consist of a housing, a display module, a battery, and a circuit board. The display module is mounted on the first side of the housing, and the second side of the housing has a battery mounting cavity for mounting the battery and a circuit board mounting cavity for mounting the circuit board. Since the display module and the circuit board need to be interconnected via flexible circuit boards, connectors, and other components, a through-hole is required at the bottom of the circuit board mounting cavity to allow the flexible circuit board and connector to pass through. However, because the through-hole needs to be sized to allow the connector to pass through, it occupies a portion of the space in the circuit board mounting cavity. Limited by the size of the through-hole, the size of the circuit board mounting cavity is difficult to compress. This results in the circuit board mounting cavity occupying a significant amount of internal space within the housing, making it difficult to increase the size of the battery mounting cavity and the battery itself. Utility Model Content

[0004] This application discloses an electronic device to solve the problem that the size of the circuit board mounting cavity is difficult to compress in the related art.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application discloses an electronic device, which includes a housing and a display module;

[0007] The housing has a first side and a second side facing away from each other. The display module is disposed on the first side of the housing. The second side of the housing has a first mounting cavity and a second mounting cavity disposed adjacent to each other. The first mounting cavity is used to install the circuit board of the electronic device, and the second mounting cavity is used to install the battery of the electronic device. The bottom of the first mounting cavity is provided with a strip-shaped through hole, and the strip-shaped through hole connects the first side of the housing and the first mounting cavity.

[0008] The display module includes a display body and a flexible electrical connection part. The first end of the flexible electrical connection part is connected to the display body, and the second end of the flexible electrical connection part passes through the strip-shaped through hole and extends into the first mounting cavity, and is used to connect to the circuit board of the electronic device.

[0009] The length direction of the strip-shaped through hole forms a first angle with the first direction, the first angle being greater than 0° and less than 180°, wherein the first direction is the arrangement direction of the first mounting cavity and the second mounting cavity.

[0010] The technical solution adopted in this application can achieve the following technical effects:

[0011] The electronic device disclosed in this application improves upon related technologies. The disclosed electronic device includes a housing and a display module. The display module is mounted on a first side of the housing. A second side of the housing has a first mounting cavity and a second mounting cavity arranged adjacent to each other. The first mounting cavity is used to mount the circuit board of the electronic device, and the second mounting cavity is used to mount the battery of the electronic device. A strip-shaped through-hole is provided at the bottom of the first mounting cavity, connecting the first side of the housing and the first mounting cavity, allowing the flexible electrical connection portion of the display module to pass through the strip-shaped through-hole and connect to the circuit board of the electronic device. The arrangement direction of the first and second mounting cavities is defined as a first direction. Since the length direction of the strip-shaped through-hole forms a first angle greater than 0° and less than 180° with the first direction, the size of the strip-shaped through-hole in the first direction can be reduced. This further compresses the size of the first mounting cavity in the first direction, freeing up more space in the first mounting cavity for the second mounting cavity to accommodate a larger battery, thus improving battery capacity.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 6This application discloses an electronic device, which can be a mobile phone, tablet computer, laptop computer, wearable device, vehicle device, etc. This application does not limit the specific type of electronic device. The aforementioned electronic device may include a housing 100 and a display module 200. The housing 100 is the structural basis of the electronic device and has a first side and a second side facing away from each other. The display module 200 is mounted on the first side of the housing 100. The display module 200 can be an LCD (Liquid Crystal Display), an LED (Light Emitting Diode) display, an OLED (Organic Light-Emitting Diode) display, etc. The display module 200 can be assembled with the housing 100 by means of adhesive bonding, snap-fitting, etc.

[0027] The second side of the housing 100 has a first mounting cavity 110 and a second mounting cavity 120 arranged adjacent to each other. The first mounting cavity 110 and the second mounting cavity 120 can be separated by a partition, and the first mounting cavity 110 and the second mounting cavity 120 are independent of each other. The first mounting cavity 110 can be used to mount the circuit board of the electronic device, which can be the motherboard or the sub-board of the electronic device. The second mounting cavity 120 is used to mount the battery of the electronic device, which can be used to power the electronic device. In addition, components such as radio frequency antennas and camera modules can also be installed inside the housing 100.

[0028] The display module 200 may include a display body 210 and a flexible electrical connection part 220. The display body 210 is used to display images, and the flexible electrical connection part 220 is used to realize the electrical connection between the display body 210 and the circuit board. The flexible electrical connection part 220 may include an FPC (Flexible Printed Circuit Board). The first end of the flexible electrical connection part 220 is connected to the display body 210, and the second end of the flexible electrical connection part 220 needs to be connected to the circuit board in the first mounting cavity 110. To facilitate the connection between the flexible electrical connection part 220 and the circuit board, a strip-shaped through hole 130 is provided at the bottom of the first mounting cavity 110. The strip-shaped through hole 130 can connect the first side of the housing 100 and the first mounting cavity 110. The second end of the flexible electrical connection part 220 can pass through the strip-shaped through hole 130 and extend into the first mounting cavity 110, and connect to the circuit board of the electronic device.

[0029] The arrangement direction of the first mounting cavity 110 and the second mounting cavity 120 is defined as the first direction 30°. In terms of a specific structure, such as... Figure 1 and Figure 2As shown, the housing 100 can be a rectangular structure. The housing 100 includes a first side 101, a second side 102, a third side 103, and a fourth side 104. The first side 101 is opposite to the second side 102, and the third side 103 is opposite to the fourth side 104. The first side 101 and the second side 102 are the two longer sides of the housing 100, and the third side 103 and the fourth side 104 are the two shorter sides of the housing 100. The extending directions of the first side 101 and the second side 102 are parallel to the first direction 300, and the extending directions of the third side 103 and the fourth side 104 are perpendicular to the first direction 300.

[0030] To achieve better battery life for electronic devices while keeping the battery energy density constant, larger batteries are needed to increase battery capacity. Installing a larger battery requires increasing the size of the second mounting cavity 120. Since the space on the second side of the housing 100 is limited, increasing the size of the second mounting cavity 120 means compressing the size of the first mounting cavity 110. However, in related technologies, the length direction of the strip-shaped through-hole 130 is usually parallel to the first direction 300. Because the size of the strip-shaped through-hole 130 needs to allow the flexible electrical connection 220 to pass through, the strip-shaped through-hole 130 has a large size in the first direction 300. The strip-shaped through-hole 130 occupies part of the space in the first mounting cavity 110. Limited by the size of the strip-shaped through-hole 130, the size of the first mounting cavity 110 in the first direction 300 is also difficult to compress. This results in the first mounting cavity 110 occupying a large amount of internal space in the housing 100, making it difficult to increase the size of the second mounting cavity 120 in the first direction 300, and consequently, the second mounting cavity 120 cannot accommodate a larger battery. It should be noted that the length direction of the strip-shaped through hole 130 generally refers to the direction of its longest dimension. The strip-shaped through hole 130 can be a rectangular or elliptical hole. Therefore, the length direction of the strip-shaped through hole 130 is the straight line direction of its long side (or major axis). The length direction of the strip-shaped through hole 130 is perpendicular to its width direction, and the width direction of the strip-shaped through hole 130 is the straight line direction of its short side (or minor axis).

[0031] Based on the above issues, such as Figure 1 and Figure 2As shown, the length direction of the strip-shaped through hole 130 can form a first angle α with the first direction 300. This first angle α is greater than 0° and less than 180°, and can be the angle by which the length direction of the strip-shaped through hole 130 is offset clockwise relative to the first direction 300. The specific angle of the first angle α can be 30°, 60°, 90°, 120°, 150°, etc. In simple terms, since the first side 101 of the housing 100 also extends along the first direction 300, the first side 101 of the housing 100 can be used as a reference. When the length direction of the strip-shaped through hole 130 is inclined relative to the first side 101, the size of the projection of the strip-shaped through hole 130 on the first side 101 will also be reduced. Therefore, the size of the first mounting cavity 110 on the first side 101 can be further compressed, thereby freeing up more space in the first direction 300 for the second mounting cavity 120, which is beneficial for installing larger batteries.

[0032] When assembling the display module 200 with the housing 100, the following assembly methods are possible:

[0033] First, the flexible electrical connection portion 220 of the display module 200 is pre-bent so that the second end of the flexible electrical connection portion 220 is bent upward and toward the strip-shaped through hole 130. The second end of the flexible electrical connection portion 220 is actually a connector. The connector itself also has a length direction and a width direction. In order for the connector to pass smoothly through the strip-shaped through hole 130, the length direction of the connector needs to be adjusted to be approximately parallel to the length direction of the strip-shaped through hole 130.

[0034] During the process of adjusting the length direction of the connector to be approximately parallel to the length direction of the through hole 130, the housing 100 or the display module 200 can be rotated clockwise or counterclockwise to switch the housing 100 and the display module 200 from a facing state to a deflected state. In the deflected state, the length direction of the through hole 130 is approximately parallel to the length direction of the connector. At this time, the connector can be smoothly passed through the through hole 130. Then, the housing 100 and the display module 200 can be switched back from the deflected state to a facing state, so that the display module 200 can be placed on the first side of the housing 100. Alternatively, since the flexible electrical connection part 220 itself has a certain degree of flexibility, the connector can also be rotated by twisting the flexible electrical connection part 220, which can also quickly achieve the goal of the connector's length direction being approximately parallel to the length direction of the through hole 130.

[0035] As can be seen from the above, the electronic device disclosed in this application improves the relevant technology. Since the length direction of the strip-shaped through hole 130 forms a first included angle α greater than 0° and less than 180° with the first direction 300, the size of the strip-shaped through hole 130 in the first direction 300 can be reduced. This allows the size of the first mounting cavity 110 in the first direction 300 to be further compressed, so that the first mounting cavity 110 can free up more space for the second mounting cavity 120 to install a larger battery, which is beneficial to increasing the battery capacity.

[0036] In one optional embodiment of this application, the first included angle α can be an acute angle, and the specific angle of the first included angle α can be 15°, 30°, 45°, 60°, 80°, etc. Figure 1 and Figure 2 Looking at it, taking the first side 101 of the housing 100 as a reference, the first included angle α is actually the angle between the length direction of the strip-shaped through hole 130 and the left side of the first side 101. When the first included angle α is an acute angle, the strip-shaped through hole 130 is close to the fourth side 104 of the housing 100, and the relative position of the strip-shaped through hole 130 and the first mounting cavity 110 is more compact, which is conducive to reducing the size of the first mounting cavity 110.

[0037] When the first included angle α is an acute angle, the first included angle α can be further refined. Specifically, the first included angle α can be greater than 30° and less than 60°. The specific angle of the first included angle α can be 40°, 45°, 50°, 55°, etc. When the first included angle α is greater than 30° and less than 60°, the strip-shaped through hole 130 can be prevented from excessively encroaching on the space near the central area of ​​the first mounting cavity 110, thereby avoiding interference with the circuit board in the first mounting cavity 110.

[0038] like Figure 3 and Figure 4 As shown, the flexible electrical connection portion 220 may include an electrical connection body 221 and a first connector 222. The first end of the electrical connection body 221 is connected to the display body 210, and the first connector 222 is disposed at the second end of the electrical connection body 221. The first connector 222 and part of the electrical connection body 221 can extend into the first mounting cavity 110 through the strip-shaped through-hole 130. To allow the first connector 222 to pass smoothly through the strip-shaped through-hole 130, the length of the strip-shaped through-hole 130 can be greater than the length of the first connector 222, and the width of the strip-shaped through-hole 130 can be greater than the width of the first connector 222.

[0039] like Figure 3 and Figure 4As shown, the electrical connection body 221 may include a first flexible portion 2211 and a second flexible portion 2212 that are interconnected. The first flexible portion 2211 is connected to the display body 210, and the second flexible portion 2212 is connected to the first connector 222. The first flexible portion 2211 and the second flexible portion 2212 can be folded along a second direction 400. The second angle formed by the second direction 400 and the length direction of the strip-shaped through hole 130 is less than a preset angle. The range of the preset angle can be greater than or equal to 0° and less than 15°. Furthermore, the second direction 400 is also set at an angle with the first direction 300. The range of this angle is close to the range of the first angle α. The angle formed by the second direction 400 and the first direction 300 can be 30°, 60°, 90°, 120°, 150°, etc., and can be selected according to the length direction of the strip-shaped through hole 130. By folding the electrical connection body 221, the length direction of the folded first connector 222 can be matched with the length direction of the strip through hole 130, thereby facilitating the passage of the second flexible part 2212 and the first connector 222 through the strip through hole 130.

[0040] To standardize the folding process of the electrical connection body 221 and minimize the deviation between the length direction of the first connector 222 and the length direction of the strip-shaped through hole 130, a folding marking line 223 can be formed on the surface of the electrical connection body 221 by means of screen printing, electroplating, etc. The folding marking line 223 is parallel to the second direction 400. In actual operation, the electrical connection body 221 can be folded along the folding marking line 223 so that the folded second flexible part 2212 and the first connector 222 can pass smoothly through the strip-shaped through hole 130.

[0041] Furthermore, the folding process of the aforementioned electrical connection body 221 can be manual or automatically folded using a bending device. Taking manual folding as an example, the operator can fold the electrical connection body 221 using a mounting fixture. The mounting fixture can be a pressure plate, a limiting bracket, or other structures. The mounting fixture can have a beveled edge, which can be parallel to the second direction 400. By pressing the mounting fixture against the top of the electrical connection body 221, the second flexible part 2212 can be bent along the beveled edge of the mounting fixture.

[0042] In one optional embodiment of this application, such as Figure 5As shown, an adhesive layer 230 is provided between the first flexible portion 2211 and the display body 210. The adhesive layer 230 is bonded to both the first flexible portion 2211 and the display body 210. The adhesive layer 230 has a folding edge 233 near the second flexible portion 2212, and the folding edge 233 is parallel to the second direction 400. When the electrical connection body 221 is folded, since the first flexible portion 2211 is bonded and fixed to the display body 210 through the adhesive layer 230, it is not easy to bend. However, the second flexible portion 2212 is not fixed, so it can be bent along the folding edge 233 of the adhesive layer 230, which helps to improve the efficiency and consistency of the folding process.

[0043] In the above embodiment, the adhesive layer 230 is an integral structure. In actual installation, in order to reduce the amount of adhesive material used, the adhesive layer 230 can also adopt a split structure. The adhesive layer 230 includes a first adhesive layer 231 and a second adhesive layer 232. The second adhesive layer 232 is located at one end of the first adhesive layer 231 near the second flexible portion 2212. There is a glue-free area between the first adhesive layer 231 and the second adhesive layer 232. The side of the second adhesive layer 232 facing away from the first adhesive layer 231 is the folded edge line 233 mentioned above.

[0044] Since the flexible electrical connection 220 inevitably twists and rubs within the strip-shaped through hole 130, to prevent the hole wall of the strip-shaped through hole 130 from scratching the flexible electrical connection 220, arc-shaped guide structures 131 can be provided at both ends of the strip-shaped through hole 130 along its own length direction. The arc-shaped guide structures can guide and cooperate with the flexible electrical connection 220, which can reduce the probability of scratching the flexible electrical connection 220 and improve the durability of the flexible electrical connection 220.

[0045] In one specific embodiment of this application, the circuit board can be a sub-board of the electronic device. The sub-board surface is provided with a second connector, and the first connector 222 is plugged into the second connector to enable quick assembly and disassembly of the display module 200. In addition, the electronic device also has a main board, and the main board and the sub-board are electrically connected.

[0046] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. For the sake of brevity, they will not be described in detail here.

[0047] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
