Description

Technical Field

[0001] The utility model relates to the field of intelligent equipment, in particular to an electronic device. Background Art

[0002] With the development of technology, electronic devices such as smartphones and Bluetooth headsets have become an indispensable part of people's daily lives. Such devices usually include a housing and a display screen, and the housing has a groove or cavity for mounting the display screen.

[0003] In the prior art, to secure the display screen within the housing, glue is typically applied between the display screen and the bottom wall of the housing, securing the screen and housing together. However, during assembly, the screen and housing must accommodate dimensional tolerances between the screen glass and the housing. This means that once the display screen is installed, there will be a certain gap between the display screen and the housing's mounting slot. This design significantly increases the difficulty of waterproofing electronic devices.

[0004] Specifically, when electronic devices in the prior art are intruded by liquid, due to the gap between the display screen and the groove body of the housing for mounting the display screen, liquid can easily penetrate into the interior of the device along these gaps, thereby affecting the normal use of the electronic device and even causing malfunctions. Especially for some electronic devices used outdoors, insufficient waterproof performance will greatly reduce the reliability and service life of the equipment. Commonly, liquid entry is prevented by providing a sealing ring between the display screen and the housing or adding waterproof materials. Although these methods can improve the waterproof performance to a certain extent, since the sealing ring is prone to aging and the selection and application of waterproof materials have high process requirements, these methods cannot solve the problem well.

[0016] In some embodiments, the housing includes a plurality of supporting portions, the supporting portions being connected to the bottom wall surface, and a side of the supporting portions facing away from the bottom wall surface being used to abut against the display assembly;

[0017] The heights of the plurality of support portions along the axis direction of the peripheral wall surface are all equal.

[0018] In some embodiments, the support portion is in the shape of an elongated strip, and the length direction of the support portion is parallel to the bottom wall surface.

[0019] In some embodiments, the distance from the side of the display assembly away from the bottom wall to the peripheral wall is L2, and the distance from the side of the display assembly close to the bottom wall to the peripheral wall is L3, and L2 and L3 satisfy:

[0023] In some embodiments, along the axis direction of the peripheral wall, the surface wall of the display assembly facing away from the bottom wall is lower than the housing;

[0024] Along the axial direction of the peripheral wall, the distance from the outer edge of the housing to the display assembly is L4, and L4 satisfies:

[0025] 0.02mm≤L4≤0.10mm.

[0026] According to the above embodiments, the beneficial effects of the present invention are:

[0027] The electronic device of the present invention includes a housing and a display assembly. The housing includes a receiving groove for receiving the display assembly. Specifically, the receiving groove has a bottom wall surface and a peripheral wall surface. The peripheral wall surface of the receiving groove is arranged around the bottom wall surface.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] In the related art, when an electronic device encounters liquid intrusion, due to the gap between the display screen and the groove body of the shell for mounting the display screen, the liquid can easily penetrate into the interior of the device along these gaps, thereby affecting the normal use of the electronic device and even causing malfunctions. Especially for some electronic devices used outdoors, insufficient waterproof performance will greatly reduce the reliability and service life of the equipment. Commonly, liquid entry is prevented by setting a sealing ring between the display screen and the shell or adding waterproof materials. Although these methods can improve the waterproof performance to a certain extent, since the sealing ring is prone to aging and the selection and application of waterproof materials have high process requirements, these methods cannot solve the problem well.

[0052] Reference below Figures 1 to 13 The electronic device according to the embodiment of the present invention is described.

[0053] Reference Figure 1 、 Figure 2 and Figure 6 In some embodiments, the electronic device of the present invention includes a housing 100 and a display assembly 200. The housing 100 includes a receiving groove 110, which is used to receive the display assembly 200. Specifically, the receiving groove 110 has a bottom wall surface 111 and a peripheral wall surface 112. The peripheral wall surface 112 of the receiving groove 110 is arranged around the bottom wall surface 111. The display assembly 200 is adhered to the bottom wall surface 111 of the receiving groove 110 by an adhesive portion. For example, the adhesive portion can be glue, preferably glue AB6068.

[0054] The bottom wall surface 111 and / or the peripheral wall surface 112 of the receiving groove 110 are provided with an avoidance groove 113, and the avoidance groove 113 is arranged around the axis of the peripheral wall surface 112. Figures 1 to 6 as well as Figure 13When the adhesive area 210 of the display assembly 200 is fixed to the housing 100 through the adhesive portion, the adhesive portion will be pressurized and spread outward, and a portion of the adhesive portion will fill the avoidance groove 113. Since the display assembly 200 is spaced apart from the bottom wall 111 and the peripheral wall 112, external water can easily penetrate into the device through these gaps, thereby affecting the normal use of the electronic device and even causing malfunctions. This solution uses the avoidance groove 113 to allow the adhesive portion filled in the avoidance groove 113 and part of the adhesive portion of the bottom wall 111 to work together to prevent water from entering the interior of the electronic device, thereby achieving a better waterproof effect at a lower cost.

[0055] The adhesive portion not only secures the display but also absorbs stress caused by temperature fluctuations, reducing deformation of the display assembly 200 due to thermal expansion and contraction, thereby improving the reliability of the display assembly 200. The adhesive portion effectively reduces stress accumulation caused by temperature fluctuations and improves the overall performance of the electronic device. The adhesive material can also be selected based on different usage environments, such as using high- or low-temperature-resistant adhesives to accommodate different temperature conditions.

[0056] It is understandable that, referring to Figures 3 to 6 The escape groove 113 can be provided on the bottom wall 111, the peripheral wall 112, or at the junction of the bottom wall 111 and the peripheral wall 112. The position of the escape groove 113 can be flexibly adjusted according to the position of the display assembly 200 to prevent the water flow from affecting the electronic components in the display assembly 200.

[0057] Reference Figures 3 to 6 In some embodiments, the avoidance groove 113 is located at the edge of the bottom wall surface 111 facing the peripheral wall surface 112, and the avoidance groove 113 connects the bottom wall surface 111 and the peripheral wall surface 112, that is, the avoidance groove 113 can also be set at the junction of the bottom wall surface 111 and the peripheral wall surface 112. In this case, the avoidance groove 113 is an annular structure surrounding the bottom wall surface 111. By arranging the avoidance groove 113 at the edge of the bottom wall surface 111 facing the side wall surface, when the bonding portion between the display component 200 and the bottom wall surface 111 is pressurized, the bonding portion is pressurized and diffused, and the adhesive material can flow smoothly and fill the avoidance groove 113, and fill the space between the bottom wall surface 111 and the peripheral wall surface 112 along the path of the avoidance groove 113. In combination with the annular avoidance groove 113, the bonding portion filled in the avoidance groove 113 will form a complete sealing ring structure. Therefore, such a setting can more effectively prevent water penetration, greatly improve the waterproof performance of the electronic device, and reduce the failure rate caused by water penetration.

[0058] It is understandable that the interconnected design of the avoidance groove 113 also helps to discharge air, reduce gaps, further improve the bonding effect of the bonding part, and enhance the fixation of the display assembly 200.

[0059] It is understood that in some embodiments, the bonding effect of the adhesive portion can be further improved by increasing the number of avoidance grooves 113. For example, multiple avoidance grooves 113 can be provided on the bottom wall 111 to better discharge air between the display assembly 200 and the housing 100 when the display assembly 200 and the housing 100 are bonded together by the adhesive portion, thereby improving the bonding effect of the adhesive portion.

[0060] Reference Figure 2 and Figure 6 The housing 100 includes a mounting groove 140, which is located on the side of the axis of the avoidance groove 113 facing the peripheral wall surface 112. The mounting groove 140 is suitable for installing electronic components. The electronic components are installed on the inner side of the avoidance groove 113. If the external water flow wants to affect the electronic components, it must pass through the avoidance groove 113. When the avoidance groove 113 is filled with the overflowing adhesive portion, the adhesive portion will block the entry of the water flow. When the avoidance groove 113 is not filled with the adhesive portion, the avoidance groove 113 itself has a water storage function, which will also limit the water flow to the position of the mounting groove 140. Such a setting not only reduces the production cost, but also can achieve a better waterproof effect in many cases.

[0061] Reference Figures 9 to 12 In some embodiments, the housing 100 includes a flange 120, which is connected to the bottom wall 111 and arranged around the axis of the peripheral wall 112. The side of the flange 120 facing the peripheral wall 112 is connected to the groove wall of the avoidance groove 113. The flange 120 with such a structural design can not only strengthen the structural strength of the housing 100 and improve the impact resistance of the electronic device, but also ensure the sealing effect between the adhesive portion and the avoidance groove 113. Specifically, the flange 120 has a guiding effect on the flow of the adhesive portion that is pressurized and diffused. The diffused adhesive portion first spreads along the edge of the flange 120 and around the flange 120. The adhesive portion at the flange 120 becomes more and more, and the adhesive portion flows into the avoidance groove 113 from multiple directions beyond the flange 120, thereby ensuring that the adhesive portion can evenly fill the avoidance groove 113 and form a good sealing effect.

[0062] It is understood that in some embodiments, the width and height of the flange 120 can be adjusted as needed to accommodate housings 100 and display assemblies 200 of varying sizes. It is also understood that the provision of the flange 120 also facilitates installation of the display assembly 200. In some embodiments, the display assembly 200 is supported by the flange 120, thereby providing a gap between the display assembly 200 and the bottom wall 111. This gap is used to arrange the adhesive portion. This arrangement provides the adhesive portion with sufficient flow space, allowing for a more even distribution of the adhesive portion, thereby improving the adhesive effect.

[0063] It is understood that in some embodiments, the width and thickness of the flange 120 can be adjusted according to actual needs to adapt to different sizes of housings 100 to ensure good sealing performance. The material of the flange 120 can also be selected according to the use environment, for example, using metal material to improve the pressure resistance of the housing 100.

[0064] Reference Figure 4 In some embodiments, the side of the flange 120 facing the peripheral wall 112 and the peripheral wall 112 are configured as two opposing sidewalls of the avoidance groove 113. The distance between the raised position of the flange 120 and the peripheral wall 112 is L1, and the range of L1 is 0.20mm≤L1≤1.0mm. For example, L1 can be 0.20mm, 0.40mm, 0.60mm, 0.80mm, 1.0mm, etc. In some embodiments, the depth of the avoidance groove 113 is in the range of [0.10mm, 0.20mm]. For example, the depth of the avoidance groove 113 can be 0.10mm, 0.13mm, 0.15mm, 0.18mm, or 0.20mm. Preferably, the depth of the avoidance groove 113 is set to 0.15mm. This configuration not only maintains a high degree of compactness of the display assembly 200 and the housing 100, preventing external dust and moisture from entering the interior of the electronic device, but also provides sufficient space for the bonding portion. The change in the distance L1 from the raised position of the flange 120 to the peripheral wall surface 112 can be achieved by changing the width or height of the flange 120 to adapt to avoidance grooves 113 and display components 200 of different sizes, ensuring that the adhesive part can effectively fill the avoidance groove 113 without affecting the normal installation and use of the display component 200.

[0065] It can be understood that in some embodiments, the thickness and height of the flange 120 can be adjusted according to the size of the display component 200 and the overall design of the electronic device, and the size of L1 can be adjusted according to the different sizes of display components 200 or the adhesive parts of different materials to better support the design of the avoidance groove 113.

[0066] It is understandable that the material of the flange 120 can be selected to have a certain elasticity, such as plastic or rubber, to enhance the sealing effect.

[0067] Regarding another function of the avoidance groove 113, in combination with the above embodiment, refer to Figure 4, the display assembly 200 extends into the avoidance groove 113, that is, the edge of the display assembly 200 is suspended in the avoidance groove 113. The edges of existing screens are usually designed to be sharp right-angled edges, but during the processing of the shell 100, due to mold limitations or to reduce stress concentration, a natural rounded corner (R angle) is often formed. The right-angled edge of the screen often contacts the natural rounded corner of the shell 100, causing interference, resulting in a series of problems such as the screen not being properly assembled, the screen protruding from the surface of the shell 100, the glue not being properly bonded, and gaps inside, which makes the screen glass fragile when it falls. In this solution, the display assembly 200 extends into the avoidance groove 113 and is suspended above the avoidance groove 113, that is, the edge of the display assembly 200 will not conflict with the shell 100, thereby avoiding such interference and the series of problems caused by such interference.

[0068] In order to further improve the bonding effect of the bonding part, refer to Figure 5 In some embodiments, the housing 100 includes a plurality of support portions 130 , each of which is connected to the bottom wall 111 . The side of the support portion 130 facing away from the bottom wall 111 is configured to abut the display assembly 200 . The heights of the plurality of support portions 130 along the axis of the peripheral wall 112 are all equal. Providing the support portions 130 ensures the stability and reliability of the display assembly 200 within the receiving groove 110 , ensuring an appropriate spacing between the display assembly 200 and the bottom wall 111 , and facilitating uniform distribution of the adhesive portion after pressure is applied. The height of the support portions 130 is designed to provide sufficient space between the display assembly 200 and the bottom wall 111 for placing adhesive material, ensuring the balance of the display assembly 200 in the horizontal plane within the housing 100 and the uniformity of the adhesive portion during bonding. This ensures that the adhesive portion formed between the display assembly 200 and the bottom wall 111 has good bonding and sealing properties, thereby enhancing the overall sealing of the electronic device and improving its waterproof and dustproof properties.

[0069] It is understood that in some embodiments, to further enhance the connection stability between the display assembly 200 and the housing 100, the support portion 130 can be designed in different shapes, such as cylindrical, rectangular, etc., to adapt to different application scenarios. In addition, the number of support portions 130 can be adjusted according to the size and shape of the display assembly 200 to ensure that the lower surface of the display assembly 200 and the bottom wall 111 of the housing 100 are more parallel and the distance between the lower surface of the display assembly 200 and the bottom wall 111 of the housing 100 is more appropriate, thereby stably fixing the display assembly 200 to the housing 100 through the adhesive portion.

[0070] Reference Figure 5In some embodiments, the support portion 130 is in the shape of an elongated strip, with the length direction of the support portion 130 parallel to the bottom wall surface 111. This design helps to increase the contact area between the support portion 130 and the display assembly 200, thereby improving the support stability. The support portion 130 adopts an elongated strip design, with the length direction parallel to the bottom wall surface 111, which increases the contact area between the support portion 130 and the display assembly 200, thereby improving the support stability and ensuring the stability of the display assembly 200. In addition, the provision of the elongated support portion 130 is also conducive to the uniform distribution of the adhesive material, further enhancing the sealing performance of the adhesive portion.

[0071] As a preferred embodiment, the length of the long strip support portion 130 is in the range of 2.0 mm to 5.0 mm, the width is in the range of 0.3 mm to 0.7 mm, and the height is in the range of 0.05 mm to 0.15 mm. Along the length of the long strip support portion 130, the spacing between two adjacent support portions 130 is in the range of 2.0 mm to 10.00 mm. This arrangement reserves sufficient clearance between the display assembly 200 and the bottom wall surface 111 for the adhesive portion to flow, and the support portions 130 are more evenly distributed, providing more stable support for the display assembly 200, thereby improving the bonding effect.

[0072] It is understood that in some embodiments, the length of the support portion 130 can be adjusted according to actual needs to accommodate display assemblies 200 of different sizes. In addition, the material of the support portion 130 can be selected to have high strength and good weather resistance to adapt to various usage environments.

[0073] Reference Figure 4, in some embodiments, the distance from the side of the display component 200 away from the bottom wall surface 111 to the peripheral wall surface 112 is L2, and the distance from the side of the display component 200 close to the bottom wall surface 111 to the peripheral wall surface 112 is L3. L2 and L3 satisfy: L3 < L2; 0.04 mm ≤ L2 ≤ 0.08 mm; 0.02 mm ≤ L3 ≤ 0.05 mm. For example, L2 can be 0.04 mm, 0.06 mm, 0.08 mm, and L3 can be 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm. When the display component 200 is assembled with the housing 100, a dimensional tolerance between the display component 200 and the housing 100 needs to be reserved, and the resulting space is the reserved tolerance gap size. Since the aesthetic appearance after the display component 200 is assembled into the housing 100 needs to be considered, this gap cannot be reserved too large. Due to the draft angle of the housing 100, the gaps at the root and the mouth positions are different. The unilateral gap reserved at the root is the above-mentioned L2, and the unilateral gap reserved at the mouth is the above-mentioned L3. With such a setting, by controlling the values of L2 and L3, on the one hand, the sealing performance between the display component 200 and the housing 100 is ensured, and on the other hand, the assembly convenience of the display component 200 can be taken into account, reducing the assembly difficulty in the production process and improving the production efficiency.

[0074] It can be understood that, in some embodiments, the specific values of L2 and L3 can be finely adjusted according to the thickness of the display component 200 and the characteristics of the adhesive material. In addition, by optimizing the selection of the adhesive material, the sealing performance can be further improved while reducing the manufacturing cost.

[0075] Refer to Figure 4 , in some embodiments, along the axial direction of the peripheral wall surface 112, the surface of the display component 200背离 the bottom wall surface 111 is lower than the housing 100. Along the axial direction of the peripheral wall surface 112, the distance from the outer edge of the housing 100 to the display component 200 is L4, and L4 satisfies: 0.02 mm ≤ L4 ≤ 0.10 mm. For example, L4 can be 0.02 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.10 mm. Since the glass perimeter of the display component 200 has sharp corners, setting the upper surface of the display component 200 lower than the housing 100 can better hide the sharp corners of the glass of the display component, protecting users from being scratched by the sharp corners, and the sharp corners cannot be seen visually, obtaining a better visual effect.

[0076] Next, comprehensively considering the structure of this solution, the design and function of the avoidance groove 113 in this solution will be systematically described. Refer to Figures 1 to 13In some embodiments, the avoidance groove 113 is provided at the junction of the bottom wall surface 111 and the peripheral wall surface 112, and the flange 120 is provided around the outer edge of the bottom wall surface 111. The side wall of the flange 120 serves as part of the side wall of the avoidance groove 113. The edge of the display component 200 extends into the avoidance groove 113 and the edge of the display component 200 is suspended in the avoidance groove 113. Therefore, the edge of the display component 200 will not interfere with the housing 100, thereby achieving a better assembly effect and a better bonding effect of the adhesive portion. After the display component 200 is connected to the housing 100 through the bonding of the adhesive portion, part of the adhesive portion will overflow and fill the avoidance groove 113, and guided by the flange 120, the adhesive portion will fill the avoidance groove 113 from multiple directions, and the filling effect is uniform. The adhesive portion filled in the avoidance groove 113 can prevent external water from entering the interior of the device, thereby improving the waterproof capability of the electronic device of this solution.

[0077] In addition, the support portion 130 is evenly distributed on the bottom wall 111, so that there is enough space between the display component 200 and the housing 100 for the adhesive portion to flow, thereby improving the bonding effect. In addition, the flange 120 surrounds the outer edge of the bottom wall 111. The flange 120 has a supporting effect on the display component 200, and the support portion 130 has a supporting effect on the display component, further ensuring the firmness of the connection between the display component 200 and the housing 100. It can be understood that the adhesive portion is more evenly distributed between the display component 200 and the housing 100. On the one hand, the bonding effect is better. On the other hand, there are fewer bubbles in the glue, and the sealing is better, further preventing external water from penetrating into the interior of the electronic device. In other words, since glue takes a long time to dry up, it is fluid before it dries. The support points are left to ensure that the glue on the contact surface between the display component 200 and the plastic shell is evenly distributed. In addition, when the display component 200 is assembled, there will be a pressure-maintaining period to fix the display component 200 and the shell 100 to wait for drying. In order to prevent the display component 200 from tilting relative to the surface of the shell 100 (such as one side lowering and the other side rising) after being subjected to pressure during pressure maintenance, the support structure can also keep the display component 200 level with the bottom wall 111 of the shell 100 during pressure maintenance, so that the glue between the display component 200 and the shell 100 can also be guaranteed to be uniform.

[0078] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
