[0056] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0057] The following is for reference. Figures 1-13 The button structure 100 according to an embodiment of the present utility model is described.
[0058] like Figure 4 and Figure 5 As shown, the button structure 100 according to the first aspect embodiment of the present utility model includes: a button 10, an electrical connection plate 20 and a button bracket 30. The button 10 is provided with a support portion 11, the electrical connection plate 20 is provided with a switch 21, the button bracket 30 is disposed between the button 10 and the electrical connection plate 20, and the button bracket 30 is provided with a gel portion 31, which is disposed between the support portion 11 and the switch 21.
[0059] Specifically, the button structure 100 mainly consists of a button 10, an electrical connection plate 20, and a button support 30. The button 10 is provided with a support portion 11. Since the button support 30 is located between the support portion 11 and the electrical connection plate 20, when the button 10 is pressed, the force is first transmitted to the colloid portion 31 through the support portion 11. The colloid portion 31 undergoes elastic deformation under the force and is then transmitted to the switch 21. The deformation mechanism of the colloid portion 31 is that its internal molecular chains rearrange to adapt to the action of external force. Once the external force disappears, the molecular chains quickly return to their original positions, causing the colloid portion 31 to restore its original shape. Therefore, the colloid portion 31 is not prone to elastic fatigue, which can extend its service life.
[0060] Since the colloid part 31 is not prone to elastic fatigue and has good elasticity, it can make the touch of the button 10 consistent, thus ensuring the feel of the button 10.
[0061] Furthermore, no metal-to-metal friction noise or noise is generated between the support portion 11 and the colloid portion 31, i.e., there is no contact noise, thereby avoiding the occurrence of noise.
[0062] Furthermore, the colloidal part 31 typically has good resistance to water, oil, chemicals, etc., and is not prone to rust or corrosion. This makes it more advantageous than metal springs in humid or chemical environments. Compared to metal springs, it is less prone to failure and has higher reliability, thus allowing it to adapt to the extreme environment on the vehicle for a long time.
[0063] Therefore, in this button structure 100, the deformation mechanism of the colloid portion 31 involves the rearrangement of its internal molecular chains to adapt to the action of external forces. Once the external force disappears, the molecular chains quickly return to their original positions, causing the colloid portion 31 to restore its original shape. This makes the colloid portion 31 less prone to elastic fatigue, thus solving the problem of traditional buttons easily failing under automotive conditions, extending its service life, and providing good elasticity, ensuring consistent tactile feedback for the button 10.
[0064] According to some embodiments of this utility model, such as Figure 6 As shown, the support portion 11 and the switch 21 abut against the opposite sides of the gel portion 31.
[0065] Specifically, when the button 10 is pressed with force, since the support part 11 is connected to the button 10, the button 10 can transmit the force to the colloid part 31 through the support part 11. The colloid part 31 undergoes elastic deformation under the force, and can transmit the force to the switch 21, thereby triggering the switch 21.
[0066] According to some embodiments of this utility model, such as Figure 8 As shown, the button bracket 30 includes: a bracket body 32, the bracket body 32 is provided with a through hole 321, and the colloid part 31 is disposed in the through hole 321.
[0067] The bracket body 32 has a through hole 321. The through hole 321 provides installation space for the colloid part 31, which facilitates the installation of the colloid part 31.
[0068] According to some embodiments of the present invention, the support body 32 is a plastic part, and the support body 32 and the colloid part 31 are integrally injection molded.
[0069] The main body 32 of the support can be made of polycarbonate (PC), and the gel part 31 can be made of thermoplastic polyurethane elastomer (TPU). The main body 32 and the gel part 31 are integrally injection molded, which can eliminate the seams or gaps in the traditional assembly method and make its structure more stable.
[0070] Furthermore, the button bracket 30 can fix the switch 21 on the electrical connection board 20 (FPC). This structure is simple to process, has high structural stability, and is easy to install, thus avoiding the defects of unstable product yield, low reliability, and easy failure after long-term use caused by directly using the guide pad base on the button 10.
[0071] Alternatively, the integrally molded colloid part 31 can be connected to the through hole 321 of the integrally molded bracket body 32. This makes it easy to install the colloid part 31 at the through hole 321 and also makes it easy to replace the colloid part 31 and the bracket body 32. When either the bracket body 32 or the colloid part 31 is damaged, it can be easily disassembled and replaced, thereby extending its service life.
[0072] According to some embodiments of this utility model, such as Figure 6 As shown, the central axis of the colloid part 31 is collinear with the central axis of the corresponding switch 21.
[0073] The central region of the colloid portion 31 is in close contact with the central region of the corresponding switch 21. This ensures that the force on the colloid portion 31 is accurately transmitted to the switch 21, resulting in high precision and facilitating assembly.
[0074] According to some embodiments of the present invention, the button bracket 30 is bonded to the electrical connection plate 20.
[0075] The button bracket 30 is bonded to the electrical connection plate 20 by adhesive backing, which facilitates the fixing of the button bracket 30 to the electrical connection plate 20 and makes the connection between the button bracket 30 and the electrical connection plate 20 more stable.
[0076] According to some embodiments of this utility model, such as Figure 4 and Figure 7 As shown, the button structure 100 also includes a buffer 40, which is disposed between the button 10 and the button support 30. The buffer 40 and the support 11 are spaced apart in the length direction of the button 10.
[0077] The buffer 40 is disposed between the button 10 and the button bracket 30. The buffer 40 can absorb vibration and noise. For example, the buffer 40 can be made of foam. Two pieces of foam can be disposed on the button 10, with the two pieces of foam spaced apart along the length of the button 10. In this way, the button 10 will not shake and make abnormal noise in the car when it is not pressed, and its structure will not be damaged.
[0078] Furthermore, the buffer 40 and the support 11 are spaced apart along the length of the button 10, so that the buffer 40 and the support 11 can effectively disperse the stress generated when the button 10 is operated. The buffer 40 can absorb most of the impact energy and reduce the direct pressure on the support 11, thereby extending the service life of the button 10.
[0079] According to specific embodiments of this utility model, such as Figure 4 and Figure 7As shown, the key 10 includes: a keycap 12, at least two support portions 11, at least two support portions 11 are disposed on the keycap 12, and at least two support portions 11 are spaced apart in the length direction of the keycap 12. The key bracket 30 includes: a bracket body 32, at least two gel portions 31, at least two gel portions 31 are disposed on the bracket body 32, and at least two gel portions 31 are spaced apart in the length direction of the bracket body 32. The at least two gel portions 31 correspond one-to-one with the at least two support portions 11.
[0080] Specifically, at least two support parts 11 are provided on the keycap 12, and correspondingly, at least two gel parts 31 are provided on the support body 32. In this way, the force between the support parts 11 and the gel parts 31 can be more balanced, and the switch 21 can be triggered by pressing on both sides of the key 10, thereby improving the stability of pressing the key 10.
[0081] Furthermore, at least two gel parts 31 are spaced apart along the length of the support body 32, and at least two gel parts 31 correspond one-to-one with at least two support parts 11. This avoids interference between the two gel parts 31. When one gel part 31 is damaged, the other gel part 31 can still work, thereby further ensuring the stability of the circuit of the button 10.
[0082] Furthermore, keycap 12 is injection molded and can be made of polycarbonate (PC). The surface can be treated with paint, UV curing coating, and anti-fingerprint (AF) treatment. Keycap 12 has functions such as waterproof, oil-proof, scratch-proof, fingerprint-proof, stain-proof, and easy-to-clean.
[0083] According to some embodiments of this utility model, such as Figure 4 and Figure 7 As shown, a protrusion 50 is provided on the side of the keycap 12 away from the support part 11, and the protrusion 50 abuts against the bracket body 32.
[0084] The protrusion 50 is located on the side of the keycap 12 away from the support portion 11. That is, the protrusion 50 is located between the two support portions 11 on the keycap 12, or the protrusion 50 is located at the center of the line connecting the two support portions 11, that is, the middle of the length direction of the keycap 12. Preferably, the protrusion 50 is located in the middle of the length direction of the keycap 12. When the middle part of the keycap 12 is accidentally pressed, since the middle part of the keycap 12 is provided with the protrusion 50, the protrusion 50 can abut against the support body 32. This can prevent the middle part from being triggered, which can effectively avoid the risk of accidental touch. Only pressing the two sides of the keycap 12 will be sensitive and effective, thereby avoiding the occurrence of accidental touch.
[0085] According to some embodiments of the present invention, the colloid portion 31 is a soft colloid portion.
[0086] Specifically, the soft rubber portion can be made of thermoplastic polyurethane elastomer (TPU), or it can be made of rubber or silicone. In this way, when the rubber portion 31 is subjected to external force, the molecular chains inside the rubber portion 31 will rearrange to adapt to the action of the external force. Once the external force is removed, the molecular chains quickly return to their original positions, thereby allowing the rubber portion 31 to restore its original shape.
[0087] like Figure 1 and Figure 12 As shown, the armrest screen 200 according to the second aspect embodiment of the present utility model further includes: a housing 60, a screen 70 and a button structure 100 as described in the above embodiment. The housing 60 is provided with a key hole 61, the screen 70 is installed on the housing 60, the electrical connection plate 20 and the button bracket 30 are disposed in the cavity formed by the housing 60, and the button 10 is disposed in the key hole 61.
[0088] The keyhole 61 on the outer casing 60 facilitates the insertion of the key 10. The outer casing 60 not only facilitates the installation of the screen 70, but also protects the screen 70.
[0089] Furthermore, the electrical connection plate 20 and the button bracket 30 are disposed within the cavity formed by the housing 60, and the housing 60 can protect the electrical connection plate 20 and the button bracket 30.
[0090] Furthermore, the outer casing 60 is provided with multiple key holes 61. For example, the outer casing 60 can be provided with three key holes 61, which are spaced apart along the length of the outer casing 60. Each key hole 61 corresponds to a button structure 100. Thus, the electrical connection plate 20 contains three switches 21. The switches 21 are surrounded by trapezoidal adhesive, which has the function of preventing fooling and precise positioning and fixing when assembled with the button bracket 30.
[0091] Meanwhile, the electrical connection plate 20 (FPC) also has adhesive backing in other locations to prevent it from sliding during installation and to avoid interfering with the assembly of other components.
[0092] According to some embodiments of the present invention, the outer shell 60 is provided with a first snap-fit portion 62, and the button bracket 30 is provided with a second snap-fit portion 33, and the first snap-fit portion 62 and the second snap-fit portion 33 are snap-fitted together.
[0093] The top of both ends of the button bracket 30 is provided with a second snap-fit part 33, which can be configured as a snap hook. Correspondingly, the first snap-fit part 62 of the outer shell 60 can be configured as a snap groove. The snap hook extends into the snap groove. In this way, the button bracket 30 and the outer shell 60 can be prevented from shaking, and the installation and removal of the outer shell 60 and the button bracket 30 can be facilitated.
[0094] According to some embodiments of this utility model, such as Figure 6As shown, the armrest screen 200 also includes: a limiting member 80, which is disposed within the housing 60. The button 10 is provided with a limiting groove 13. A portion of the limiting member 80 is located within the limiting groove 13, and a portion of the limiting member 80 is adapted to engage with the end of the limiting groove 13 for limiting.
[0095] The limiting member 80 can be set as a pin, with a part of the pin extending into the limiting groove 13 of the button 10. In this way, the limiting member 80 is located between the button 10 and the button bracket 30. The limiting member 80 can fix the button bracket 30 and the button 10, which facilitates production and assembly, and also ensures the reliability between the button 10 and the button bracket 30.
[0096] Furthermore, a portion of the limiting member 80 is adapted to engage with the end of the limiting groove 13 for limiting, thereby preventing movement between the button 10 and the limiting member 80 and thus fixing the button 10.
[0097] According to some embodiments of this utility model, such as Figure 9 and Figure 11 As shown, the outer shell 60 is provided with a recessed portion 63, and the recessed portion 63 forms a receiving groove 631. The screen 70 is disposed in the receiving groove 631. An annular groove 64 is formed between the recessed portion 63 and the outer peripheral edge of the outer shell 60. A reinforcing rib 90 connecting the recessed portion 63 and the outer peripheral edge of the outer shell 60 is provided at the position of the groove 64 corresponding to the end corner of the outer shell 60.
[0098] The inclusion of the receiving slot 631 provides an installation location and space for the screen 70, thus facilitating its installation.
[0099] Furthermore, the groove 64 formed between the recessed portion 63 and the outer peripheral edge of the outer shell 60 facilitates the setting of the reinforcing rib 90. This increases the strength and rigidity between the recessed portion 63 and the outer shell 60, and also prevents deformation. Since the armrest screen 200 is mounted on the outer shell 60, it can prevent the armrest screen 200 from being deformed by side impacts during use, and also solves the problem that traditional vehicle electronic devices are easily damaged by impacts during vehicle use.
[0100] Furthermore, the reinforcing ribs 90 can be set at the corners of the outer shell 60. For example, the four corners of the outer shell 60 can be provided with reinforcing ribs 90. This can prevent the four corners of the outer shell 60 from being impacted, and can also prevent the corners of the armrest screen 200 from being impacted and deformed during use.
[0101] According to some embodiments of this utility model, such as Figure 1As shown, the outer shell 60 includes a top shell 601 and a bottom shell 602, which are connected. The button bracket 30 and the electrical connection plate 20 are disposed between the top shell 601 and the bottom shell 602. The key hole 61, the recess 63 and the reinforcing rib 90 are all disposed on the top shell 601.
[0102] The top shell 601 is the main carrier of the button structure 100. The top shell 601 facilitates the fixed installation of the button 10, the button bracket 30 and the limiting member 80.
[0103] The surface treatment of the top shell 601 includes spray painting, screen printing of text or patterns, ultraviolet curing coating (UV), and anti-fingerprint (AF). After surface treatment, the material is lightweight, hard, and textured, and has functions such as waterproof, oil-proof, scratch-proof, fingerprint-proof, stain-proof, and easy to clean.
[0104] The bottom shell 602 facilitates the installation of the circuit board 91, thus protecting it. The button bracket 30 and the electrical connection plate 20 are positioned between the top shell 601 and the bottom shell 602, protecting them respectively.
[0105] Furthermore, keyhole 61, recess 63, and reinforcing rib 90 are all provided on top shell 601. The keyhole 61 facilitates the installation of key 10, the recess 63 facilitates the placement and installation of screen 70, making it more stable, and the reinforcing rib 90 further improves the strength of top shell 601, thereby preventing it from deforming.
[0106] According to some embodiments of this utility model, such as Figure 12 As shown, the armrest screen 200 also includes a circuit board 91 and a message connector 92. The circuit board 91 is disposed in the cavity formed by the housing 60 and is electrically connected to the electrical connection board 20. The message connector 92 is disposed on the circuit board 91, and the housing 60 is provided with an interface opposite to the message connector 92.
[0107] The circuit board 91 is located inside the cavity of the housing 60 and serves to protect the circuit board 91. The circuit board 91 (PCBA) is equipped with a message connector 92. The circuit board 91 is electrically connected to the electrical connection board 20, which enables the circuit connection between the circuit board 91 and the electrical connection board 20. The message connector 92 is located on the circuit board 91, and the circuit board 91 provides an installation position for the message connector 92 to achieve circuit connection.
[0108] Furthermore, the housing 60 is provided with an interface opposite to the message connector 92, which facilitates the insertion of an external message reader. When a fault occurs, the message can be read by plugging an external message reader into the message connector 92, allowing engineers to understand the state at the time of the fault. This helps engineers understand the process and result of the fault, thereby deduce the cause of the fault and ultimately help them find a suitable solution.
[0109] Furthermore, the top shell 601 and the bottom shell 602 also serve to fix the limiting member 80. Specifically, the top shell 601 and the bottom shell 602 together press down on the limiting member 80, thereby making its structure more stable.
[0110] According to some embodiments of the present invention, the outer casing 60 is provided with a plurality of waterproof barriers 93 surrounding the circuit board 91.
[0111] Specifically, the bottom shell 602 has three rings of waterproof barriers 93. The gap between the bottom shell 602 and the top shell 601 is small, which can prevent water from entering the equipment, thereby protecting the circuit board 91 (PCBA) and achieving an IP5k3 dustproof and waterproof rating. At the same time, the bottom shell 602 can further stabilize the limiting component 80, thus ensuring the feel and stability of the buttons 10. A message connector 92 interface is also provided, eliminating the need to remove the circuit board 91 (PCBA) of the armrest screen 200 for fault detection, thus facilitating the identification of the fault source and improving maintenance efficiency.
[0112] According to some embodiments of this utility model, such as Figure 13 As shown, the bottom of the outer casing 60 is provided with a disassembly port 94.
[0113] The pry bar can be inserted through the disassembly port 94 to pry open the armrest screen 200. When the armrest screen 200 malfunctions or needs to be repaired, it can facilitate the disassembly of the armrest screen 200, thereby increasing the disassembly speed and reducing the damage to the armrest screen 200 caused by the tool during the disassembly process.
[0114] The handrail according to a third aspect of the present invention includes: the handrail screen 200 of the above embodiment.
[0115] Depending on the usage environment and requirements, the PC material of the top shell 601, bottom shell 602, button 10, limiter 80 and button bracket 30 can be replaced with other materials, such as PC+ABS, etc. The gel part 31 (TPU) of the button bracket 30 can be replaced with silicone or other materials as needed.
[0116] Furthermore, the angle between the entire screen 70 and the plane after installation should be between 10° and 30°. If the angle is less than 10°, passengers will not be able to clearly see the information on the screen. Therefore, the angle between the entire screen 70 and the plane after installation should not be less than 10°. If the angle is greater than 30°, the angle between the screen 70 and the plane will be too large, making it difficult to install the screen 70 on the top shell 601 and also easily damaging the screen 70. For example, the angle between the entire screen 70 and the plane after installation can be set to 13°, 15°, and 25°. This not only conforms to ergonomics and is convenient for passengers to use, but also protects the screen 70. Additionally, due to the physical buttons 10, passengers can adjust the seat and backrest without seeing the screen 70, and there are one-touch comfort and one-touch recovery functions, making operation convenient, ergonomic, and highly reliable.
[0117] Furthermore, both the screen 70 and the casing 60 are equipped with anti-fingerprint AF technology, which can improve the user experience, thereby reducing the impact of fingerprints on the display of the screen 70, making it easier to clean after use, and also resisting wear and tear during daily use.
[0118] Furthermore, conductive foam is provided on the circuit board 91 to discharge static electricity generated on the circuit board 91 (PCBA), thereby preventing static electricity from damaging the components on the circuit board 91 (PCBA).
[0119] Also, here are the assembly steps for the armrest screen 200:
[0120] Use screws to fasten the screen 70 to the top cover 601;
[0121] Use screws to fasten the top cover 601 to the circuit board 91;
[0122] Insert the electrical connection plate 20 into the designated position on the circuit board 91 and fix it to the back of the electrical connection plate 20 by double locking with the fixing mechanism on the circuit board 91.
[0123] The button bracket 30 is mounted on the top shell 601 and fixed by a buckle. The button bracket 30 has a hook and the top shell 601 has a matching slot.
[0124] First, install the buttons, then install the limiting component 80 onto the top shell 601, using slight interference to secure the buttons and limiting component 80. Finally, use screws to secure each of the three button positions.
[0125] The bottom shell 602 is secured to the top shell 601 using screws, forming the main structure of the armrest screen 200.
