Abstract
Description
Technical Field
[0001] This application relates to the field of electronic equipment technology, and more specifically, to a housing assembly, electronic equipment, and wireless communication terminal. Background Technology
[0002] With the development of electronic technology, various electronic devices such as smartphones, wearable devices, and smart home controllers have been widely used in people's daily lives. These devices typically contain complex internal circuits and sensitive components. Therefore, their housing components not only need to provide an aesthetically pleasing appearance and a comfortable feel, but also need to have good waterproof performance and blind operation to adapt to various complex usage environments.
[0003] Traditional electronic device housings are mostly injection molded from a single material. The button areas often lack sufficient elastic cushioning, resulting in stiff button feel and susceptibility to damage from prolonged use or external impacts. Furthermore, traditional designs often use separate buttons and housings, leaving gaps at the connection point. This increases the risk of moisture penetration and reduces the device's waterproof performance.
[0004] In terms of blind operability, traditional designs often neglect the user's operational needs without visual assistance. For example, the button area and the surrounding housing are made of materials with similar hardness, making it difficult for users to accurately distinguish the button positions by touch and feel, thus affecting the device's usability and user experience. Therefore, how to enhance the waterproof performance and blind operability of button functions has become an urgent problem to be solved. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0024] See Figure 1-5 The housing assembly provided in this application includes: a front shell 101, a pressing part 102, a circuit board 104, and a bottom shell 105; the circuit board 104 includes a first trigger 1041; the pressing part 102 and the first trigger 1041 abut against each other; the front shell 101 includes a pressing area 101, and the pressing part 102 is disposed inside the pressing area 101; the material hardness of the pressing area 101 is lower than the material hardness of the pressing part 102, and the pressing area 101 and the pressing part 102 are integrally molded by two-material injection molding; the bottom shell 105 accommodates the circuit board 104, and the front shell 101 and the bottom shell 105 form the outer shell of the electronic device.
[0025] In this embodiment, the front shell 101 and the bottom shell 105 together constitute the outer casing of the electronic device, forming a relatively enclosed space that effectively prevents external moisture from corroding the internal circuit board 104. The pressing area 101 and the pressing part 102 are manufactured using a dual-material injection molding process to ensure the structural strength and stability of the pressing part 102. The selection of a material with lower hardness for the pressing area 101 provides a certain degree of elastic cushioning and sealing. When the pressing part 102 is subjected to external force, the pressing area 101 can undergo slight deformation, resulting in a good tactile feedback. Furthermore, the tight contact design between the pressing part 102 and the first trigger 1041 reduces the possibility of moisture entering the circuit board 104 through gaps. Therefore, this housing assembly has high reliability and durability in terms of button waterproofing performance, making it suitable for use in various outdoor sports scenarios.
[0026] Regarding blind operability, the pressing part is cleverly positioned inside the pressing area, and the material of the pressing area is less hard than that of the pressing part, allowing users to clearly distinguish the location of the pressing part when touched. Even without visual assistance, users can accurately locate and trigger the button through touch and feel. Furthermore, the tight contact design between the pressing part and the first trigger ensures the sensitivity and accuracy of button triggering. Users only need to apply slight force to trigger the first trigger on the circuit board, thereby completing the corresponding operation. This design not only improves the ease of use and user experience of the device but also makes this housing assembly perform exceptionally well in applications requiring blind operation, such as wearable devices and smart home controllers.
[0027] In one implementation, see Figure 1-5 The housing assembly also includes a knob 103, and the circuit board 104 also includes a second trigger 1042, with the knob 103 connected to the second trigger 1042; the faceplate 101 also includes a knob area 1012, with the knob 103 disposed in the knob area 1012, the knob area 1012 being close to the top corner of the faceplate 101; the knob area 1012 is provided with a mounting groove 1014a, the mounting groove 1014a accommodating the knob 103, and the rotation axis of the knob 103 being perpendicular to the surface of the faceplate 101.
[0028] In this embodiment, the functions of the pressing part 102 and the knob 103 are arranged in separate zones, so that the pressing part 102 is close to the side of the face shell 101 and the knob 103 is close to the face shell 101. This makes it easy for the operator to operate the knob 103 while pressing, or to operate the pressing part or the knob 103 separately without interference. This achieves a balance between ease of operation, aesthetic appearance, and compact structure.
[0029] See Figure 1-5The separate design of the pressing area 1011 and the knob area 1012 avoids mutual interference between the pressing part 102 located in the pressing area 1011 and the knob 103 located in the knob area 1012 during operation. The pressing area 1011 extends away from the knob area 1012, increasing the operable area of the pressing part 102. When the user performs the pressing operation, their fingers can be naturally placed near the side of the faceplate 101, and pressing the pressing part 102 controls the first trigger 1041.
[0030] In this embodiment, the rotation axis of the knob 103 is perpendicular to the surface of the faceplate 101, enhancing the stability and smoothness of the knob 103's operation. By positioning the knob area 1012 at the top corner of the faceplate 101, and designing a mounting groove 1014a in the faceplate 101 to accommodate the knob 103, the knob 103 maintains its ease of operation while occupying a small space. This layout effectively improves the internal space utilization of the housing assembly, making the overall structure of the housing assembly more compact.
[0031] See Figure 1-5 The circuit board 104 integrates a first trigger 1041 and a second trigger 1042, which correspond to the pressing part 102 and the knob 103 respectively, realizing the integration of multiple operation modes. Users can control the circuit board 104 by controlling the pressing part 102 and the knob 103, thereby realizing the corresponding multiple functions.
[0032] See Figure 1-5 In actual operation, the user drives the pressing part 102 by pressing the pressing area 1011 with the thumb, while the index finger can naturally approach the top corner of the face shell 101 to operate the knob 103. The two operations can be performed simultaneously or separately, and the pressing part 102 and the knob 103 can be controlled at the same time, realizing the diversification of operation methods and improving the user experience.
[0033] In one implementation, see Figure 1-5 The projected area of the surface of the face shell 101 in the first direction is S1, and the projected area of the pressing area 1011 in the first direction is S2. S1 and S2 satisfy: 0.25S1≤S2<S1, and the first direction is perpendicular to the surface of the face shell 101.
[0034] In this embodiment, the ratio between S2 and S1 is 0.25S1≤S2<S1, ensuring that the pressing area occupies a relatively large area proportion on the surface of the face shell without occupying the entire surface. While satisfying the condition 0.25S1≤S2<S1, the size and position of the pressing area 1011 can be adjusted according to specific application scenarios and user needs.
[0035] See Figure 1-5The larger pressing area (1011) means that users have more room for error when operating, and can trigger the function without aligning the pressing point, thereby improving the convenience of operation and user experience, especially for application scenarios that require fast response or frequent operation.
[0036] It should be understood that by rationally allocating the space of the pressing area 1011 and other areas, every inch of the surface shell 101 can be utilized to the maximum extent, achieving a compact structure for the shell assembly. This not only helps to reduce the size and weight of the shell assembly, but also improves the utilization rate of the internal space of the shell assembly.
[0037] In one implementation, see Figure 1-5 The front cover 101 also includes a display area 1013, and the circuit board 104 includes a display unit 1043 facing the display area 1013; the display area 1013 and the knob area 1012 are located on the same side of the pressing area 1011. By providing a display area 1013 on the front cover 101 and equipping it with a corresponding display unit 1043, the housing assembly can intuitively display various information, such as status prompts, operation feedback, and data display. This instant and intuitive information display method enhances the information interaction capability between the user and the device, improving the ease of use of the device and the user experience.
[0038] See Figure 1-5 In the embodiments of this application, the display area 1013 and the knob area 1012 are arranged on the same side of the pressing area 1011, and the display area 1013, the knob area 1012, and the pressing area 1011 are all located on the surface of the faceplate 101. During operation, the user can simultaneously observe the information in the display area 1013 and the positions of the knob 103 and the pressing area 1011. This layout reduces the need for the user to switch their gaze between different operating areas, enabling the user to form a coherent visual and operational flow during operation.
[0039] In this embodiment, the display area 1013, knob area 1012, and pressing area 1011 are arranged on the same side, which can effectively utilize space resources and make the overall structure of the housing assembly more compact. It is suitable for miniaturized and portable devices, and can improve the portability and comfort of the housing assembly.
[0040] In one implementation, see Figure 1-5The faceplate 101 also includes a support area 1014, which forms a mounting groove 1014a at its apex corner. The support area 1014 connects the pressing area 1011 and the knob area 1012. The material hardness of the pressing area 1011 is lower than that of the support area. The mounting groove 1014a at the apex corner of the support area 1014 can be used to mount the knob 103, providing a stable mounting base for the knob 103. The knob occupies the space at the apex corner, making the structure more compact, while the knob 103 is located at the edge, making it easy for the user to operate. The support area 1014 connects the pressing area 1011 and the knob area 1012, making the transition between these two operating areas more natural and enhancing the overall design's unity.
[0041] In this embodiment, the hardness of the material in the pressing area 1011 is lower than that in the support area 1014. That is, the pressing area 1011 uses a softer material to provide better tactile feedback. When the user presses the pressing area 1011, the soft material provides a certain degree of elasticity and feedback, resulting in a good tactile feel and allowing the user to clearly perceive whether the pressing action has been successfully triggered. The hard support area 1014 can support the pressing area 1011 and the knob area 1012, thereby providing more effective support and protecting the internal structure.
[0042] It should be understood that the material of the pressing area 1011 includes thermoplastic polyurethane, a polymer material with high elasticity and wear resistance. Combining the elasticity of rubber and the processing characteristics of plastic, it can be injection molded or extruded. In addition, thermoplastic polyurethane has high wear resistance, good elasticity and toughness, and a certain degree of hardness. When pressed, it deforms and sinks as a whole, triggering the first trigger 1041. After the pressing pressure is removed, it can recover its deformation, avoiding continuous pressing of the first trigger 1041, thus demonstrating good practicality.
[0043] In this embodiment, the pressing area 1011 and the support area 1014 are distinguished by different material hardness. Users can easily identify different functional areas by touch, enabling accurate operation even when visibility is limited. This is suitable for blind operation scenarios, broadens the application range of the housing component, and improves the ease of use of the housing component.
[0044] In one implementation, see Figure 1-5 The faceplate 101 also includes a support area 1014, which forms a mounting groove 1014a at the top corner of the faceplate 101. The mounting groove 1014a is notched, and the wall of the notch matches the circumferential surface of the knob 103.
[0045] In this embodiment, the user can operate the knob through the notch to control its rotation direction and angle, thereby adjusting the second trigger. The knob can be configured as a dial with a gear-shaped circumference, providing a certain degree of anti-slip effect during operation and facilitating easier control of the dial's rotation to adjust the second trigger and achieve the corresponding function.
[0046] In this embodiment, part of the knob 103 is exposed through a notch at the mounting groove 1014a, so the outer edge of the knob 103 can be seen from the side of the faceplate 101. In actual operation, the user can operate the knob 103 through the notch to control the rotation direction and rotation angle of the knob 103, thereby achieving the effect of adjusting the second trigger 1042.
[0047] In this embodiment, the knob 103 can be configured as a dial. The periphery of the dial is gear-shaped, which provides a certain anti-slip effect when the user operates it, and makes it easier to control the rotation of the dial, thereby adjusting the second trigger 1042 to achieve the corresponding function.
[0048] It should be understood that the mounting groove 1014a can be used to accommodate the knob 103 so that the knob 103 does not protrude from the surface of the face shell 101, and the entire surface of the face shell 101 presents a smooth transition state. While ensuring the aesthetic appearance, the mounting groove 1014a can also protect the knob 103.
[0049] In one implementation, see Figure 1-5 The support area 1014 and the pressing area 1011 are integrally molded using two-material injection molding. Because the support area 1014 and the pressing area 1011 are integrally molded using two-material injection molding technology, gaps or loosening problems that may occur during subsequent assembly are avoided, thereby enhancing the structural strength and stability of the entire shell 101. Two materials with different properties can be used to form the support area 1014 and the pressing area 1011 respectively. The support area 1014 may be made of a high-strength, high-rigidity material to enhance structural stability, while the pressing area 1011 may be made of a more elastic and wear-resistant material to optimize the tactile feel.
[0050] In one implementation, see Figure 1-5 The pressing part 102 is flat and has multiple through holes 1021 arranged at intervals. The flat pressing part 102 provides a large contact area, allowing the user to have more contact points when pressing, thereby more effectively controlling the first trigger 1041 and increasing the comfort and stability of operation.
[0051] The multiple spaced through holes 1021 on the pressing part 102 increase its elasticity. When the user presses the button, the through holes 1021 ensure that the pressing part 102 deforms to a certain extent, thereby absorbing some pressure and providing better feedback. The through holes 1021 also improve the heat dissipation performance of the circuit board 104 below the pressing part 102, allowing air to circulate through the through holes 1021 and carry away some heat, thus helping to extend the service life of the circuit board 104 and its components. The presence of the through holes 1021 can balance the pressure in different areas during the pressing and releasing of the button, reducing the stickiness of the pressing action.
[0052] In one implementation, see Figure 1-5 The housing assembly also includes a bottom housing 105, which houses a circuit board 104. The circuit board 104 further includes a third trigger 1044. A positioning hole is provided on the first side of the bottom housing 105, through which the third trigger 1044 protrudes. The third trigger 1044 can support more functions or operating modes; for example, it can be a button or switch for performing specific tasks or adjusting settings. The third trigger 1044 protruding from the positioning hole on the first side of the bottom housing 105 allows users to operate it directly through the hole without opening the device or navigating complex operating paths, thus improving operational convenience.
[0053] In one implementation, the housing assembly also includes a speaker, with the bottom housing 105 accommodating the speaker; the speaker is connected to a circuit board 104; a sound outlet is provided on the second side of the bottom housing 105, and the speaker faces the sound outlet. The speaker in the housing assembly enhances audio playback functionality, allowing users to enjoy a richer multimedia experience. The speaker is housed inside the bottom housing 105 and connected to the circuit board 104. The sound outlet on the second side of the bottom housing 105 allows the sound emitted by the speaker to be directly transmitted to the external environment, reducing sound reflection and loss within the housing, thereby improving audio clarity and loudness. Simultaneously, the sound outlet ensures that sound is evenly and widely diffused, providing users with a more immersive listening experience.
