Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a front shell component and an intelligent terminal. Background Art

[0002] With the development of science and technology and the progress of society, the use of mobile phones has become more and more popular and has become the most widely used electronic product in people's daily life. The mobile phone screen includes a front shell and a screen lens embedded in the front shell. A connecting colloid is arranged between the inner edge of the front shell and the edge of the screen lens to achieve a stable connection and waterproof effect of the mobile phone screen.

[0003] In the process of conceiving and implementing this application, the inventors found that there are at least the following problems: the existing method of setting the sealing colloid during the production of mobile phone screens is to inject sealant on the back to achieve overall sealing, that is, first, foam glue is set on the two sides inside the front shell, hot melt glue is set on the upper and lower sides, and glue injection holes are opened at the four corners of the front shell. The screen lens is installed on the front of the front shell, and the foam glue and hot melt glue are connected and sealed by injecting glue into the injection holes to achieve overall sealing. However, the sealing method of opening holes and injecting glue on the back cannot visually detect the shape after glue injection, so it is impossible to judge the airtightness after glue injection, and additional airtightness detection is required, which has high production costs; on the other hand, the back glue injection requires that the center of the glue injection hole is within 1.5mm from the hot melt glue position, otherwise the glue flow length is large, it is difficult to ensure sealing, the operation is difficult, and the production efficiency is low.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The main purpose of the utility model is to provide a front shell component, aiming to achieve overall sealing by means of front glue dispensing, reduce production costs, reduce operating difficulty, and improve production efficiency.

[0006] To achieve the above-mentioned purpose, the front housing assembly proposed by the utility model includes:

[0007] A front shell, wherein a receiving groove is formed in a concave shape on the front side surface of the front shell, and a glue dispensing groove is formed in a corner of the bottom wall of the receiving groove;

[0008] A sealing component, the sealing component comprising two foam glues, two first sealants and a second sealant, the foam glues are arranged on the sides of the bottom of the receiving groove along the length direction of the front shell, the first sealant is arranged on the sides of the bottom of the receiving groove along the width direction of the front shell, the ends of the adjacent foam glues and the ends of the first sealant both extend to the notch edge of the glue dispensing groove, and the second sealant is arranged in the glue dispensing groove;

[0009] The display screen is pressed into the receiving groove, and the second sealant diffuses and connects the first sealant and the foam sealant.

[0010] Optionally, the adjacent ends of the foam glue and the first sealant extend to the notch edge of the glue dispensing groove.

[0011] Optionally, a height difference between a notch of the glue dispensing groove and the first sealant is 0.6 mm to 0.65 mm.

[0012] Optionally, a dispensing height of the second sealant on a side close to the first sealant is greater than a dispensing height of the second sealant on a side close to the foam sealant.

[0013] Optionally, the depth of the glue dispensing groove is 0.08 mm to 0.12 mm.

[0014] Optionally, the width of the glue dispensing groove is 1.55 mm to 1.65 mm.

[0015] Optionally, two ends of the first sealant are respectively connected to two opposite sides of the two foam sealants.

[0016] Optionally, the distance between the edge of the foam glue and the side wall of the receiving groove is 0.2 mm to 0.3 mm.

[0017] Optionally, an escape opening is formed in a recessed manner at the end edge of the foam glue, and an inner wall surface of the escape opening is adapted to be matched with an outer wall of the glue dispensing groove.

[0018] The utility model also provides an intelligent terminal, comprising the front shell assembly as described above.

[0019] The technical solution of the utility model is to set a glue point groove at the bottom corner of the receiving groove of the front shell, and the sealing component includes two foam glues, two first sealants and a second sealant. The foam glue is set at the side of the bottom of the receiving groove along the length direction of the front shell, and the first sealant is set at the side of the bottom of the receiving groove along the width direction of the front shell. The ends of the adjacent foam glues and the ends of the first sealant extend to the notch edge of the glue point groove. The second sealant is set in the glue point groove. In this way, when the display screen is pressed into the receiving groove, the pressure will diffuse the second sealant and flow to the first sealant and the foam glue, that is, fill the space gap between the first sealant and the foam glue to achieve a sealing effect. In addition, the front slotted glue point method is adopted, and the glue path detection equipment is used to perform glue path detection to determine the airtightness of the front shell and the display screen after pressing, thereby ensuring the sealing consistency, without the need for additional airtightness detection, and reducing the production cost; on the other hand, the second sealant only needs to be aligned with the glue point groove for glue point, and the glue point groove can maintain the position of the second sealant, which is simple to operate and has high production efficiency.

[0036] The utility model provides a front shell component 1, such as Figures 1 to 7 As shown, the front shell assembly 1 includes:

[0037] The front shell 10 has a front side surface with a receiving groove 11 formed therein, and a glue dispensing groove 111 is formed at a corner of a bottom wall of the receiving groove 11;

[0038] The sealing assembly 30 includes two foam glues 31, two first sealants 33 and a second sealant 35. The foam glue 31 is arranged on the side of the bottom of the receiving groove 11 along the length direction of the front shell 10, the first sealant 33 is arranged on the side of the bottom of the receiving groove 11 along the width direction of the front shell 10, and the second sealant 35 is arranged in the glue dispensing groove 111;

[0039] The display screen 50 is pressed into the receiving groove 11 , and the second sealant 35 spreads and connects the first sealant 33 and the foam sealant.

[0040] In this embodiment, the front shell 10 is recessed to form a receiving groove 11. The provision of the receiving groove 11 not only provides an installation space for the display screen 50, but also effectively protects the edge and internal components of the display. The sealing assembly 30 includes two foam glues 31, two first sealants 33 and a second sealant 35. The foam glue 31 is provided at the side of the bottom of the receiving groove 11 along the length direction of the front shell 10, and the first sealant 33 is provided at the side of the bottom of the receiving groove 11 along the width direction of the front shell 10. In this arrangement, the foam glue can correspond to the sealing of the side in the length direction after the display is connected to the front shell 10, and both sides are provided with foam glue, thereby achieving the sealing of both sides in the length direction; the first sealant 33 can correspond to the sealing of the side in the width direction after the display is connected to the front shell 10, and both sides are provided with the first sealant 33, thereby achieving the sealing of both sides in the length direction.

[0041] Optionally, a glue dispensing groove 111 is recessed at the corner of the bottom wall of the receiving groove 11, and the cross-sectional shape of the glue dispensing groove 111 can be circular, rectangular, square, etc., which is not limited here. Optionally, the glue dispensing groove 111 is located between the end of the adjacent foam glue 31 and the end of the first sealant 33, that is, the end of the adjacent foam glue 31 and the end of the first sealant 33 both extend to the notch edge of the glue dispensing groove 111. When the second sealant 35 is disposed in the glue dispensing groove 111, the display is pressed into the receiving groove 11, and the second sealant 35 diffuses along the glue dispensing groove 111 and extends to the first sealant 33 and the foam glue at both ends, and is connected with the first sealant 33 and the foam glue. After the second sealant 35 is cured, it forms a tight annular sealing structure with the first sealant 33 and the foam glue, thereby sealing the gap at the rear edge of the connection between the front shell 10 and the display. Optionally, the second sealant 35 not only diffuses and connects the first sealant 33 and the foam glue, but also forms a solid screen support structure. This arrangement not only improves the stability and durability of the display screen 50, but also further enhances the waterproof and dustproof capabilities of the entire electronic product. Through the synergistic effect of the foam glue 31, the first sealant 33 and the second sealant 35, the front shell 10 can effectively prevent moisture from entering the interior of the electronic product, thereby protecting the circuits and components from damage. This sealing design not only improves the durability of the product, but also provides users with a more secure use experience.

[0042] Optionally, in order to improve the shock resistance of the front housing 1, the foam glue 31 is a soft material that can absorb and disperse force when impacted, thereby reducing damage to the internal components of the product. This shock-resistant design allows electronic products to better protect user data security and user experience when facing accidental falls or other external impacts.

[0043] Optionally, compared with the sealing method of dispensing glue by opening holes on the back of the front shell 10, the method of dispensing glue by opening grooves on the front side can be used. After dispensing the second sealant 35, the glue path detection equipment can be used to detect the arrangement and distribution of the glue path and the glue amount, so as to determine whether the second sealant 35 can connect the foam glue and the first sealant 33 after the front shell 10 and the display screen 50 are pressed together, and the first sealant 33 and the foam glue can be sealed to achieve a sealed connection, so as to achieve the sealing of the gap at the edge after the front shell 10 and the display are connected. Under the premise of ensuring the sealing performance by adopting this method of dispensing glue, there is no need to add additional airtightness detection, which saves production time and reduces production costs; on the other hand, the second sealant 35 only needs to be aligned with the dispensing groove 111 for dispensing, and the dispensing groove 111 can maintain the position of the second sealant 35, which is simple to operate and has high production efficiency.

[0044] The technical solution of the utility model is to provide a glue dispensing groove 111 at the bottom corner of the receiving groove 11 of the front shell 10, and the sealing assembly 30 includes two foam glues 31, two first sealants 33 and a second sealant 35. The foam glue 31 is provided at the side of the bottom of the receiving groove 11 along the length direction of the front shell 10, and the first sealant 33 is provided at the side of the bottom of the receiving groove 11 along the width direction of the front shell 10. The ends of the adjacent foam glues 31 and the ends of the first sealant 33 both extend to the notch edge of the glue dispensing groove 111, and the second sealant 35 is provided in the glue dispensing groove 111. In this way, when the display screen 50 is pressed into the receiving groove 11, the pressure will diffuse the second sealant 35 and flow to the first sealant 33 and the foam glue, that is, fill the space gap between the first sealant 33 and the foam glue to achieve a sealing effect. In addition, by adopting the front groove dispensing method, the airtightness of the front shell 10 and the display screen 50 after pressing can be determined by using the glue path detection equipment to ensure the sealing consistency. There is no need for additional airtightness detection, which reduces the production cost. On the other hand, the second sealant 35 only needs to be aligned with the glue dispensing groove 111 for dispensing. The glue dispensing groove 111 can maintain the position of the second sealant 35, which is simple to operate and has high production efficiency.

[0045] Optionally, the ends of the adjacent foam glue 31 and the ends of the first sealant 33 both extend to the notch edge of the glue dispensing groove 111 .

[0046] In this embodiment, the end of the foam glue 31 and the end of the first sealant 33 are both located at the notch edge of the glue dispensing groove. The end of the foam glue 31 and the end of the first sealant 33 are both precisely set at the notch edge of the glue dispensing groove. This layout design not only optimizes the structure of the product, but also enhances its sealing and stability. By accurately positioning the end of the foam glue 31 at the notch edge, it is possible to ensure that the glue is evenly distributed, avoid problems such as bubbles or glue overflow, and thus improve the bonding quality of the product. By accurately positioning the end of the first sealant 33 at the notch edge, it is possible to ensure that the first sealant 33 can completely fill the gap, forming an effective barrier, thereby protecting the product from the external environment.

[0047] Optionally, the height difference between the notch of the glue dispensing groove 111 and the first sealant 33 is 0.6 mm to 0.65 mm.

[0048] In this embodiment, when the height difference between the notch of the dispensing groove 111 and the first sealant 33 is 0.6 mm to 0.65 mm, it plays a vital role in ensuring the dispensing effect and product quality. When the height difference between the notch and the first sealant 33 is controlled within this range, the fluidity and distribution of the second sealant 35 during the dispensing process can be effectively controlled, thereby ensuring the uniformity and consistency of the second sealant 35.

[0049] Optionally, the height difference design also takes into account convenience and flexibility in actual operation. When the height difference is too large, the second sealant 35 may not be able to connect to the first sealant 33, affecting the sealing effect; and when the height difference is too small, the second sealant 35 may flow too fast and overflow after diffusion, affecting the use of the display. Therefore, the height difference of 0.6mm to 0.65mm is the optimal design value obtained after comprehensive consideration of multiple factors.

[0050] Alternatively, if Figure 5 , Figure 6 As shown, the glue dispensing height of the second sealant 35 close to the first sealant 33 is greater than the glue dispensing height of the second sealant 35 close to the foam sealant 31 .

[0051] In this embodiment, the dispensing height of the second sealant 35 near the first sealant 33 is greater than the dispensing height near the foam glue 31. With such a configuration, when dispensing, the dispensing port can be located in the dispensing groove 111 near the first sealant 33 for multiple dispensings, or a single long-term dispensing can be performed, and the dispensing amount near the first sealant 33 can be greater than the dispensing amount near the foam glue 31. Due to the configuration of the receiving groove 11 of the front shell 10, a step is provided at the dispensing position of the first sealant 33, so the dispensing position of the first sealant 33 is higher than the dispensing position of the foam glue. The dispensing amount of the second sealant 35 is set to be different, which can effectively ensure that the second sealant 35 is diffused and connected with the first sealant 33 and the foam glue. After the second sealant 35 is cured, it forms a tight annular sealing structure with the first sealant 33 and the foam glue.

[0052] Optionally, the depth of the glue dispensing groove 111 is 0.08 mm to 0.12 mm.

[0053] In this embodiment, the groove depth is set between 0.08 mm and 0.12 mm. This range can ensure that the second sealant 35 can fully fill the dispensing groove 111 after dispensing, and effectively diffuse between the first sealant 33 and the foam glue 31 when the display screen 50 is pressed, forming a tight seal.

[0054] Optionally, the width of the glue dispensing groove 111 is 1.55 mm to 1.65 mm.

[0055] In this embodiment, the setting range of the groove width is between 1.55 mm and 1.65 mm, which can adapt to display screens 50 of different sizes and shapes, ensuring that the display screen 50 can be evenly stressed during pressing, and achieving a good sealing effect. In addition, under the premise of ensuring the flow direction of the second sealant 35, the position of the second sealant 35 can be maintained to ensure its diffusion direction.

[0056] Alternatively, if Figure 1 As shown, two ends of a first sealant 33 are respectively connected to two opposite sides of the two foam adhesives 31 .

[0057] In this embodiment, the two ends of a first sealant 33 are respectively connected to the two opposite sides of the two foam glues 31. In this way, part of the first sealant 33 is located between the two opposite sides of the two foam glues 31. This part of the first sealant 33 can cover and seal the components inside the front shell 10, thereby achieving isolation and filling between the display and the components inside the front shell 10, and preventing water vapor and dust from entering the interior of the front shell 10.

[0058] Optionally, the distance between the edge of the foam glue 31 and the side wall of the receiving groove 11 is 0.2 mm to 0.3 mm.

[0059] In this embodiment, the distance between the edge of the foam glue 31 and the side wall of the receiving groove 11 is set between 0.2 mm and 0.3 mm. When the distance is too small, the foam glue 31 may not be able to expand effectively when it is squeezed and deformed, resulting in an uneven display screen 50 after lamination, thereby affecting the bonding effect. When the distance is too large, the width of the foam glue 31 may be too small, resulting in it being easily loosely bonded or the connection between it and the display is insufficient, thereby affecting the stability and reliability of the product.

[0060] Alternatively, if Figures 1 to 7 As shown, the end edge of the foam glue 31 is recessed to form an escape opening, and the escape opening is arranged around the groove edge of the glue dispensing groove 111.

[0061] In this embodiment, the setting of the avoidance port, which is set around the notch edge of the glue dispensing groove 111, not only optimizes the flow performance of the glue, but also improves the precision and efficiency of glue dispensing. The design of the avoidance port helps to reduce the resistance of the glue during the glue dispensing process. During the use of the foam glue 31, the glue needs to flow out through the glue dispensing groove 111, and the existence of the avoidance port allows the glue to flow out more smoothly, reducing the possibility of glue dispensing failure caused by glue blockage or poor flow. In addition, the design of the avoidance port also helps to improve the precision of glue dispensing. In some scenes where the distribution of glue needs to be precisely controlled, the existence of the avoidance port can make the glue flow to the predetermined position more accurately, avoiding the glue dispensing deviation caused by the unstable flow of glue. The design of the avoidance port also helps to improve the efficiency of glue dispensing. In the continuous glue dispensing process, due to the existence of the avoidance port, the glue can flow out more quickly, thereby improving the speed and efficiency of glue dispensing. This not only saves time, but also reduces production costs.

[0062] Optionally, the first sealant 33 is polyurethane hot melt adhesive, and the second sealant 35 is silicone adhesive.

[0063] In this embodiment, the polyurethane hot melt adhesive is a sealant applied after being heated to a molten state. It has the characteristics of rapid curing, good chemical resistance, excellent elasticity, etc., can effectively absorb vibration and impact, protect the connection parts from damage, and effectively bond the display and the front shell 10.

[0064] Optionally, silicone glue is a sealant based on silicone polymer, which has excellent high temperature resistance, good weather resistance, excellent water resistance and good chemical resistance. After curing, it forms a waterproof barrier, which can effectively prevent moisture from penetrating through the sealing layer, ensuring that the sealing effect is long-lasting and reliable, and effectively maintaining the sealing of the connection between the first sealant 33 and the foam glue.

[0065] Optionally, the utility model further provides a smart terminal, which includes a front shell component 1. The specific structure of the front shell component 1 refers to the above embodiment. Since the smart terminal adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0066] The intelligent terminal of the utility model has the advantages of simple structure, good sealing effect, high production efficiency, low cost, etc., and can be widely used in various intelligent terminals that require the display screen 50 to be sealed, such as mobile phones, tablet computers, etc.
