Description

Technical Field

[0001] This manual relates to the field of mechanical buttons, and in particular to a type of button. Background Technology

[0002] Buttons are indispensable control components in electronic devices, and their performance and stability directly affect product performance and user satisfaction. Most existing buttons employ a cantilever design, which generally consists of a button body, a cantilever, and mounting holes. The cantilever is designed according to the internal space, and its size and shape directly determine the button's feel and comfort; therefore, the cantilever design is crucial for cantilever buttons. However, cantilever buttons often have extremely high requirements for the dimensional accuracy of both the cantilever and the mounting holes. This stringent requirement not only increases the manufacturing difficulty and cost of cantilever buttons, but also, in practical applications, even minute tolerances can lead to misalignment after assembly, resulting in button wobble, poor feel, and even affecting trigger accuracy.

[0003] Therefore, it is necessary to propose a button that can adapt to design tolerances, ensuring product performance while reducing the precision requirements of other structures. Utility Model Content

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings required to be used in the embodiment description will be briefly introduced below. Obviously, the drawings in the following description are only some examples or embodiments of the present specification, and those skilled in the art can also apply the present specification to other similar scenarios without creative labor on the basis of the drawings. Unless it is obvious from the language environment or otherwise stated, the same reference numerals in the drawings represent the same structure or operation.

[0025] The key is an indispensable key component in the current electronic product design and manufacturing field, especially in the design of touch devices, remote controllers, keyboards and various control panels and other products. The performance and stability of the key are directly related to the overall performance of the product and the user experience.

[0026] The existing cantilever type key often has very high requirements for the size precision of the cantilever and the size precision of the assembly hole. Such strict requirements not only increase the processing difficulty and cost of the cantilever type key, but also in actual application, even a small tolerance can cause the key to be eccentric after installation, thereby causing the key to shake, the hand feeling to be poor, and even affecting the triggering accuracy.

[0027] In view of this, some embodiments of the present specification provide a key. Through the mechanical structure design of the bushing, the key body, the shell and the like, the key can be self-adapted to the design tolerance after assembly. Even in the presence of tolerance, it can well realize the tolerance inclusiveness, maintain good operation hand feeling and triggering accuracy, reduce the processing difficulty and cost, and improve the overall quality of the product and the user experience.

[0028] Figure 1 is an assembly schematic diagram of a key according to some embodiments of the present specification.

[0029] In some embodiments, as shown in Figure 1 , the key 100 includes a key body 110, a bushing 120 and a shell 130. The key body 110 includes a pressing portion 111 and a connecting portion 112, the pressing portion 111 is connected with the connecting portion 112, and the bushing 120 is sleeved on the connecting portion 112. The shell 130 is provided with a stepped through hole, the stepped through hole includes a small aperture hole matched with the pressing portion 111 and a large aperture hole matched with the connecting portion 112, and the large aperture hole and the small aperture hole are communicated; the pressing portion 111 is arranged in the small aperture hole, and the connecting portion 112 is arranged in the large aperture hole.

[0030] The key body 110 is a structure for key functions in the key 100.

[0031] The pressing part 111 is a part for bearing the key pressing function. In some embodiments, the pressing part can be a part of the physical key of the electronic device that is directly contacted by the user. The pressing part 111 can bear the pressure applied by the user's finger. In some embodiments, the pressing part 111 is used to transmit the pressure. For example, the pressure applied by the user's finger is transmitted to the electronic key, so that the electronic key is triggered. When the electronic key is triggered, various functions can be implemented. For example, at least one of adjusting the sound volume, adjusting the sound playing speed, pausing, and starting the multi-function. The electronic key can be located on the moving path of the pressing part 111. For example, the electronic key can be located below the pressing part 111. Below the pressing part 111 is the direction away from the shell 130.

[0032] The electronic key refers to a key that realizes the input of functions in an electrical or electronic manner. In some embodiments, the electronic key is connected to the control system of the device through a circuit, for realizing the transmission of user input and instructions.

[0033] In some embodiments, when assembling the key, the connecting part 112 can be aligned with the electronic key, or the supporting part 140 can be aligned with the electronic key. The specific number, layout and type of the electronic key depend on the specific functions of the device and the user's needs. For more information about the connecting part 112 and the supporting part 140, see the relevant description later.

[0034] In some embodiments, the pressing part 111 is a cylinder, a rectangular column, or any other feasible structure. In some embodiments, the front surface of the pressing part 111 can be circular, square, or other shapes that are convenient for pressing, and is designed with appropriate inclination angles or radii to improve the operation comfort. The front surface of the pressing part 111 is the surface that bears the force applied by the user's finger.

[0035] In some embodiments, the front surface of the pressing part 111 can include various forms. For example, at least one of a smooth surface, a frosted surface, a surface with anti-slip patterns, and the like, to provide different tactile sensations. By using a frosted surface or a surface with anti-slip patterns, the friction between the user's finger and the key can also be increased to prevent slipping.

[0036] In some embodiments, the pressing part 111 is made of metal materials, wood, plastic, or any other feasible materials.

[0037] The connecting part 112 is a part connected to the pressing part 111.

[0038] In some embodiments, the connecting portion 112 is in any feasible structural form, such as a cylinder, a rectangular column, etc. In some embodiments, the pressing portion 111 and the connecting portion 112 can be in the same shape, for example, both in the shape of a cylinder. In some embodiments, the pressing portion 111 and the connecting portion 112 can be in different shapes, for example, the pressing portion 111 is in the shape of a rectangular column, and the connecting portion 112 is in the shape of a circular column, etc.

[0039] In some embodiments, as shown in FIG. 1B, the width of the connecting portion 112 along the direction perpendicular to the axis direction W is smaller than the width of the pressing portion 111 along the direction perpendicular to the axis direction W, so that the pressing portion 111 is arranged in a small-diameter hole, and the connecting portion 112 is arranged in a large-diameter hole. For example, when the pressing portion 111 and the connecting portion 112 are both in the shape of a cylinder, the diameter of the pressing portion 111 is smaller than the diameter of the connecting portion 112. Figure 1

[0040] In some embodiments, the pressing portion 111 and the connecting portion 112 can be in shapes respectively matching the small-diameter hole and the large-diameter hole, for example, when the pressing portion 111 and the connecting portion 112 are both in the shape of a cylinder, the small-diameter hole and the large-diameter hole are both in the shape of a cylinder. More details about the small-diameter hole and the large-diameter hole will be described later.

[0041] In some embodiments, the connecting portion 112 is designed with a connecting interface matching the sleeve 120, such as a threaded hole, a buckle slot, etc., so that the sleeve 120 can be stably sleeved on the outside of the connecting portion 112. More details about the sleeve 120 will be described later.

[0042] The connecting portion 112 can be connected with the pressing portion 111 in various ways. In some embodiments, the pressing portion 111 and the connecting portion 112 are integrally formed (such as injection molding). In some embodiments, the connecting portion 112 is fixedly connected with the pressing portion 111 through any feasible assembly method (such as screwing, buckle connection, etc.). Such a connection relationship needs to ensure that the key can remain stable when being pressed and effectively transmit the operation instruction.

[0043] In some embodiments, the back surface of the pressing portion 111 is connected with the connecting portion 112, and the back surface of the pressing portion 111 is arranged opposite to the front surface of the pressing portion 111. The user can trigger the function of the key by pressing the pressing portion 111. For example, when the user presses the pressing portion 111, the pressing portion 111 moves towards the direction away from the front surface of the pressing portion 111, and drives the connecting portion 112 to move towards the direction away from the front surface of the pressing portion 111, until the connecting portion 112 abuts against the electronic key, and the pressure applied by the user's finger is transmitted to the electronic key, so that the electronic key is triggered.

[0044] It should be noted that, Figure 1 ​The key body 110 in the figure is only for illustration, and the key body 110 can also be in other forms.

[0045] The bushing 120 is a structure for fixing the key body 110. For example, the bushing 120 can be a rubber ring or a plastic ring.

[0046] In some embodiments, the shape of the bushing 120 is adapted to the shape of the connecting part 112, so that the bushing 120 can be sleeved on the connecting part 112.

[0047] In some embodiments, the bushing 120 can be a three-dimensional ring shape, and the outer ring of the bushing 120 is provided with a plurality of deformable limiting ribs in the circumferential direction. For more description of this embodiment, see Figure 2 and the related description.

[0048] In some embodiments, the bushing 120 is a key component of the key 100, and needs to enable the connecting part 112 to be clamped in a large-aperture hole inside the shell 130, so as to ensure that the key body 110 can be assembled and clamped in the shell 130. Therefore, the material of the bushing 120 can be limited according to its function.

[0049] In some embodiments, the bushing 120 is made of a flexible material.

[0050] The flexible material refers to a functional material with high flexibility and scalability. In some embodiments, the flexible material includes but is not limited to rubber, plastic, fabric, etc.

[0051] In some embodiments of the present specification, the bushing 120 uses a flexible material. When the bushing 120 is assembled into the large-aperture hole of the shell 130, the bushing 120 can be deformed to adapt to the shape and size of the large-aperture hole, and at the same time help to adjust the position of the bushing 120, so that the bushing 120 moves to a predetermined position in the large-aperture hole. Moreover, the flexible material enables the bushing to bear force uniformly during the process of being squeezed into the large-aperture hole, avoiding the problem of local stress concentration, which helps to prolong the service life of the bushing 120 and the shell 130 and reduce the risk of damage caused by stress concentration. In addition, the flexible material has good sealing performance, which can ensure that the gap between the bushing 120 and the shell 130 is effectively sealed, preventing impurities such as liquid, gas or dust from invading the inside of the key (for example, the electronic key inside) through the stepped through hole on the shell 130. In addition, in a vibration or impact environment, the flexible material can absorb part of the energy, play a role in shock absorption and noise reduction, and protect the internal structure and equipment from damage.

[0052] In some embodiments, the bushing 120 can be partially or completely sleeved on the connecting portion 112. For example, when the connecting portion 112 is a cylinder, the bushing 120 can be a circular ring and sleeve a part of the connecting portion 112, or completely sleeve the connecting portion 112.

[0053] In some embodiments, the position where the connecting portion 112 meets the pressing portion 111 is provided with a chamfer structure 113, and the inner wall of the bushing 120 is provided with a bevel structure 122 that matches the chamfer structure 113. For more information about the chamfer structure 113 and the bevel structure 122, please refer to Figure 3 and related content.

[0054] In some embodiments, the bushing 120 deforms to a certain extent, which can limit the key body 110 in the stepped through hole of the shell 130, so as to ensure the stability of the cooperation between the key body 110 and the shell 130. When the key 100 is working, the bushing 120 is concentric with the stepped through hole of the shell 130 and the key body 110. When the key body 110 is pressed, the bushing 120 deforms again under force, so that the shell 120 is uniformly stressed, and the relative positional relationship between the key body 110 and the shell 130 is stable.

[0055] It should be noted that, Figure 1 The bushing 120 in may only be used as an example, and the bushing 120 can also be in other forms.

[0056] The shell 130 is used to accommodate and protect the key body 110. For example, the shell 130 can be a remote controller shell, a mobile phone shell, a computer shell, an electrical appliance shell, an industrial equipment shell, etc.

[0057] In some embodiments, the shell 130 is provided with a stepped through hole.

[0058] The stepped through hole refers to a through hole formed by nesting a plurality of holes with different hole diameters and showing a stepped shape.

[0059] In some embodiments, the stepped through hole can be composed of two or more holes with different hole diameters arranged in any manner. In some embodiments, the stepped through hole includes a small-diameter hole that cooperates with the pressing portion 111 and a large-diameter hole that cooperates with the connecting portion 112. The small-diameter hole refers to the hole with a smaller hole diameter in the stepped hole. The size of the small-diameter hole is matched with the pressing portion 111 to accommodate the pressing portion 111. The large-diameter hole refers to the hole with a larger hole diameter in the stepped hole. The size of the large-diameter hole is matched with the connecting portion 112 to accommodate the connecting portion 112.

[0060] In some embodiments, when an external force presses the pressing portion 111, the pressing portion 111 moves in the small-diameter hole, and the connecting portion 112 moves in the large-diameter hole.

[0061] It should be noted that, Figure 1 The shell 130 in the figure is only for illustrative purposes.

[0062] Some embodiments of the present specification include the following beneficial effects: (1) By dividing the key body 110 into a pressing part 111 and a connecting part 112, and matching the small aperture hole and the large aperture hole on the shell 130 respectively, the precise positioning and stable installation of the key body 110 and the shell 130 are achieved. (2) The bushing 120 is sleeved on the connecting part 112, which further enhances the stability and sealing between the connecting part 112 and the shell 130, reduces the shaking and loosening of the key during use, and improves the durability of the product and the user's experience. (3) The pressing part of the key body 110 is designed to directly contact the user's fingers, and by precisely matching the small aperture hole on the shell, it can ensure uniform force during pressing and reduce friction, thereby improving the smoothness of pressing and the hand feel. (4) The design of the stepped through hole and the cooperation of the bushing 120 can limit the position of the key body 110 in the stepped through hole, thereby avoiding uneven gaps between the key body 110 and the stepped through hole.

[0063] This is particularly important for devices used in humid or dusty environments, which can effectively prolong the service life of the product and reduce the failure rate caused by impurities.

[0064] Figure 2 is a structural schematic diagram of the bushing according to some embodiments of the present specification.

[0065] In some embodiments, as shown in Figure 2 The bushing 120 is a three-dimensional annular shape, and the outer ring of the bushing 120 is provided with a plurality of deformable limiting ribs 121 in the circumferential direction; the bushing 120 is clamped and concentric with the large aperture hole through the limiting ribs 121.

[0066] In some embodiments, when the bushing 120 is designed as a three-dimensional annular shape, the inner diameter size is consistent with the size of the connecting part 112.

[0067] So that the limiting ribs can gradually deform and tightly fit on the edge of the large aperture hole. This design helps to provide multi-directional support and fixation on the connecting part 112 of the key 100, improving the stability of the key 100. In some embodiments, the material of the bushing 120 can be plastic or rubber, etc.

[0068] The limiting rib 121 refers to a deformable structural member for limiting or fixing the position, range of motion or shape of an object. In some embodiments, the limiting rib 121 is made of an elastic material to achieve the function of deformation. For example, the limiting rib 121 can be made of plastic, rubber or other materials.

[0069] In some embodiments, the deformable limiting ribs are in a three-dimensional arc shape. In some embodiments, the limiting ribs 121 are in a sheet or fin shape. For example, a sheet or fin shape similar to a fan blade or a boat paddle blade.

[0070] In some embodiments, the limiting ribs 121 can be arranged on the outer ring of the bushing 120 in various ways. For example, by bonding or by being integrally formed.

[0071] In some embodiments, the shape of the limiting ribs 121 can be adapted according to the size and shape of the large-diameter hole when the key body 110 is assembled into the stepped through-hole of the shell 130. Due to the elasticity of the limiting ribs 121, the limiting ribs 121 can abut against the large-diameter hole under the action of the elastic force, so as to ensure the accurate alignment and stable connection between the key body 110 and the shell 130. By adjusting the shape and position of the limiting ribs 121 when the key body 110 is assembled into the stepped through-hole of the shell 130, the concentric arrangement of the bushing 120 and the stepped through-hole can be achieved.

[0072] The limiting ribs 121 can include multiple limiting ribs. In some embodiments, the multiple limiting ribs 121 can be uniformly arranged on the outer ring of the bushing 120 to ensure uniform deformation of the bushing 120. In some embodiments, the multiple limiting ribs 121 can be divided into multiple groups, each group including multiple limiting ribs 121. Each group of limiting ribs 121 is arranged along the circumferential direction of the outer ring of the bushing 120, and different groups of limiting ribs 121 are arranged along the axial direction of the outer ring of the bushing 120.

[0073] It should be noted that, Figure 2 For example only, the number and shape of the limiting ribs are not limited.

[0074] In some embodiments of the present specification, by arranging the deformable limiting ribs 121 on the bushing 120, the key body 110 can be adaptively assembled into the stepped through-hole of the shell 130 even when the stepped through-hole of the shell 130 has a large tolerance, and the bushing 120 can be concentric with the stepped through-hole, ensuring the accurate alignment and tight connection between the bushing 120 and the shell 130, and further enhancing the overall stability of the key. As an intermediary between the connecting part 110 and the shell 130, the bushing 120 can reduce friction caused by direct contact, making the key more smooth and better in hand feeling when pressed. The design of the bushing makes the assembly process of the key more simple and fast, reducing production cost and assembly difficulty.

[0075] Figure 3 FIG. 5 is a structural schematic diagram of a chamfer structure and an inclined angle structure according to some embodiments of the present specification.

[0076] In some embodiments, as shown in Figure 3 The chamfer structure 113 is provided at the position where the connecting portion 112 meets the pressing portion 111. The inner wall of the bushing 120 is provided with a bevel structure 122 matching the chamfer structure 113.

[0077] In some embodiments, the chamfer structure 113 can be a rounded chamfer structure or a bevel chamfer structure.

[0078] In some embodiments, the chamfer structure 113 can be provided on the connecting portion 112, near the position where the connecting portion 112 meets the pressing portion 111.

[0079] In some embodiments, the bevel structure 122 can be a rounded chamfer structure or a bevel chamfer structure. The angle and / or size of the bevel structure 122 matches the angle and / or size of the chamfer structure 113.

[0080] In some embodiments, the bevel structure 122 can be provided on the bushing 120, near the position where the connecting portion 112 meets the pressing portion 111.

[0081] It should be noted that, Figure 3 For example only, the shape of the chamfer structure 113 and the bevel structure 122 is not limited.

[0082] The chamfer structure 113 can reduce stress concentration and optimize flow, which helps the key body 110 move more smoothly in the stepped through hole, making assembly easier. With the cooperation of the bevel structure 122 and the chamfer structure 113, the assembly direction of the key body 110 when assembled into the stepped through hole can be guided, avoiding the phenomenon of the key body 110 deviating to one side.

[0083] Figure 4 is an assembly schematic view of the support portion according to some embodiments of the present specification. Figure 5 is a structural schematic view of the bushing provided outside the support portion according to some embodiments of the present specification.

[0084] In some embodiments, as shown in Figure 4 , Figure 5 The key 100 further includes a support portion 140 provided below the connecting portion 112, and the bushing 120 is provided outside the support portion 140. The lower side of the connecting portion 112 is the direction away from the side of the connecting portion 112 connected to the pressing portion 111.

[0085] The support portion 140 is a component for supporting the key body 110. The bushing 120 can be provided outside the support portion 140 and the connecting portion 140.

[0086] In some embodiments, the support portion 140 is in the shape of a cylinder, a rectangular cylinder, or any other feasible shape. In some embodiments, the support portion 140 and the connecting portion 112 can be in the same shape, for example, both in the shape of a cylinder. In some embodiments, the support portion 140 and the connecting portion 112 can be in different shapes, for example, the connecting portion 112 is in the shape of a cylinder and the support portion 140 is in the shape of a rectangular cylinder.

[0087] In some embodiments, the key body 110 can be connected to the support portion 140 via the connecting portion 112. The connection can be fixed, detachable, or any other feasible connection. In some other embodiments, the support portion 140 is not connected to the key body 110, and the key body 110 is placed on the support portion 140. Under the action of gravity, the connecting portion 112 is in contact with the support portion 140.

[0088] The support portion 140 needs to provide a movable space and a resettable ability for the key body 110 during the pressing process of the key body 110. Therefore, the material of the support portion 140 can be adapted to its function.

[0089] In some embodiments, the support portion 140 is made of elastic material, for example, rubber, spring, or any other feasible elastic material.

[0090] In some embodiments of the present disclosure, the support portion 140 is made of elastic material. These materials have good resilience and durability, and can provide appropriate resistance and feedback when pressed by the user, while ensuring the long-term performance of the key.

[0091] In some embodiments, when the key body 110 is pressed by external force, the key body 110 moves towards the support portion 140, and the support portion 140 deforms under the action of pressure to provide a movable space for the key body 110. Since the support portion 140 is made of elastic material, it can quickly recover to its original shape after the pressure is released, thereby realizing the rebound function of the key. At the same time, the deformation of the support portion 140 is also transmitted to the user through the connecting portion of the key, providing clear pressing feedback to the user.

[0092] It is worth noting that, Figure 4 , 5 For example only, the shape of the support portion 140 and the connection between the support portion 140 and the connecting portion 112 are not limited.

[0093] In some embodiments of the present disclosure, the support portion 140 serves as the basic part of the key structure, providing stable support for the connecting portion 112 and the pressing portion 111, and enabling the key body 110 to move a certain distance when pressed. The presence of the support portion 140 effectively prevents the key 100 from shaking and tilting during the pressing process, ensuring the accuracy and reliability of the key.

[0094] Figure 6 is a structural schematic diagram of a cantilever according to some embodiments of the present specification.

[0095] In some embodiments, as shown in Figure 6 The cantilever 141 is in abutment with the side of the connecting portion 112 away from the pressing portion 111.

[0096] The cantilever 141 is an arm-shaped structure with elasticity. The cantilever can be used to support and rebound the key body 110. In some embodiments, the shape of the cantilever 141 can be a straight arm, an arc-shaped arm, or an S-shaped arm, etc. In some embodiments, the cantilever 141 can be made of elastic materials such as silica gel, rubber, or spring steel, etc. The deformation and rebound of the cantilever 141 will affect the position and movement of the key body 110, thereby triggering the function of the key.

[0097] In some embodiments, the cantilever 141 is located on the side of the support portion 140 facing the connecting portion 112 (hereinafter referred to as the front surface of the support portion 140). In some embodiments, the connection between the cantilever 141 and the front surface of the support portion 140 can be integrally formed. In some embodiments, the connection between the cantilever 141 and the front surface of the support portion 140 can also include any feasible way such as welding, bonding, etc.

[0098] In some embodiments, when the key body 110 (for example, the pressing portion 111) is pressed by external force, the pressing portion 111 and the connecting portion 112 move towards the support portion 140 and press the cantilever 141, which will be elastically deformed. With further pressing of the key body 110 (for example, the pressing portion 111), the deformation of the cantilever 141 gradually increases until it reaches the trigger point (for example, the set position point of the cantilever 141 contacts the electronic key), and the electronic key triggers the function of the key 100. When the key body 110 (for example, the pressing portion 111) is released, the key body 110 (for example, the pressing portion 111 and the connecting portion 112) will return to the original position under the rebounding force of the cantilever 141, realizing the rebound of the key 100.

[0099] In some embodiments, the support portion 140 is a three-dimensional ring shape, and the cantilever 141 includes a plurality of cantilevers 141 distributed along the circumference of the support portion 140.

[0100] In some embodiments, the support portion 140 can be a three-dimensional ring shape, and the outer ring size of the support portion 140 can be adapted to the inner ring size of the bushing 120, so as to reduce the gap between the support portion 140 and the bushing 120 and ensure the stability of the structure of the key 100.

[0101] In some embodiments, the plurality of cantilevers 141 can be evenly distributed along the circumferential direction of the inner ring of the support portion 140. The circumferential distribution can ensure that the key is effectively supported and feedbacked in all directions when the key 100 is pressed.

[0102] In some embodiments of the present specification, the three-dimensional annular shape and the circumferential distribution of the cantilevers collectively enhance the anti-torsion and anti-bending capabilities of the key, so that the key can maintain stable shape and function when subjected to various forces. The evenly distributed cantilevers provide balanced pressing feedback to the user, and the user can obtain consistent feel and experience when pressing the key from all directions.

[0103] It is worth noting that, Figure 6 For example only, the shape, size, etc. of the cantilever can be adjusted according to specific requirements and design.

[0104] The cantilever 141, as part of the support portion 140, enhances the stability of the key 100 structure. It can provide additional support force when the key 100 is pressed, preventing unnecessary deformation or damage of the key 100. The cantilever 141 is usually made of elastic material and has good rebound performance. When the key 100 is released, the cantilever 141 can quickly recover to the original shape, providing clear rebound feedback to the key 100. This feedback mechanism enhances the user experience, allowing the user to accurately perceive the pressing state of the key. During the pressing process of the key 100, the cantilever 141 can absorb and disperse the pressure, preventing the pressure from concentrating on the connecting portion 112 or other weak parts. This helps to prolong the service life of the key and improve its durability.

[0105] Figure 7A is an assembly schematic diagram of the fixed plate (without support portion) according to some embodiments of the present specification. Figure 7B is an assembly schematic diagram of the fixed plate (with support portion) according to some embodiments of the present specification.

[0106] In some embodiments, as shown in Figure 7A , Figure 7B The key 100 further comprises a fixed plate 150 provided with at least one positioning hole 151 and an electronic key (not shown in the figure), and the inner side surface of the shell 130 is provided with at least one positioning column 131 corresponding to the electronic key; at least one positioning column 131 is arranged in at least one positioning hole 151 to connect the shell 130 and the fixed plate 150.

[0107] The fixing plate 150 is a structure in the key 100 for fixing other components of the key 100. For example, the shell 130 can be fixed on the fixing plate 150, and the components such as the key body 110, the support part 140, etc. contained inside the shell 130 will be surrounded by the shell 130 and fixed together on the fixing plate 150.

[0108] In some embodiments, the material of the fixing plate 150 can be silica gel, plastic, stainless steel, etc. In some embodiments, the fixing plate 150 can be a PCB board.

[0109] The positioning hole 151 is a hole position for positioning and fixing, and the positioning column 131 is a columnar structure for positioning and fixing.

[0110] In some embodiments, the positioning column 131 and the shell 130 can be firmly connected through welding, screw fixing or other means to ensure the stability and reliability of the positioning column 131.

[0111] During assembly, the shell 130 can be fixed on the fixing plate 150 through the matching connection of the positioning hole 151 and the positioning column 131, so as to tightly connect each part of the key 100 together and prevent loosening or misalignment during use. For example, the positioning column 131 is inserted into the positioning hole 151, so that the shell 130 is fixed on the fixing plate 150. At the same time, after the positioning column 131 is inserted into the positioning hole 151, the gap between the positioning column 131 and the positioning hole should be moderate, ensuring that it is neither too large to cause shaking nor too small to cause assembly difficulty.

[0112] In some embodiments, the positioning hole 151 can be a threaded hole or any other feasible hole structure, and the positioning column 131 can be a screw or any other feasible columnar structure. The positioning hole 151 and the positioning column 131 can be fixed on the fixing plate 150 through threaded connection.

[0113] In some embodiments, the positioning hole 151 of the fixing plate 150 matches the positioning column 131 on the shell 130, which can fix the shell 130 on the fixing plate 150 to achieve accurate positioning and fixing. For example, the size, number, shape and position of the positioning hole 151 and the positioning column 131 can be one-to-one corresponding matching. In some embodiments, the size, number, shape and position of the positioning hole 151 and the positioning column 131 are determined according to design requirements to ensure the stability and ease of use of the key assembly.

[0114] The fixing plate 150 is mainly used to stably fix the internal components (such as the key body 110, the support part 140, etc.) of the key 100 inside the shell 130. It ensures the accurate positioning and stable connection of the internal components of the key 100, preventing loosening or damage caused by external factors such as vibration and impact.

[0115] Figure 7A For illustrative purposes only, it is worth noting that this instruction manual does not impose any restrictions on the shape or material of the fixing plate.

[0116] In some embodiments of this specification, at least one positioning hole 151 provided on the fixing plate 150 matches at least one positioning post 131 on the inner surface of the housing 130. By having the positioning post 131 pass through the positioning hole 151, precise positioning and a stable connection between the housing 130 and the fixing plate 150 are achieved. This design not only simplifies the assembly process but also significantly reduces assembly errors and improves the overall precision of the product. The cooperation between the positioning post 131 and the positioning hole 151 not only serves a positioning function but also enhances the structural strength between the housing 130 and the fixing plate 150 through physical connection. This enhancement effect helps resist external impacts and vibrations, extending the service life of the button 100.

[0117] In some embodiments, such as Figure 7A As shown, button 100 includes a button body 110, a bushing 120, a housing 130, and a fixing plate 150. In this embodiment, button 100 is not a cantilever button; for example, button 100 can be a silicone button. In this case, the electronic button on the fixing plate 150 can achieve its function by contacting the connecting portion 112 of button 100. For example, when the button body 110 (e.g., the pressing portion 111) is pressed by an external force, the pressing portion 111 and the connecting portion 112 move toward the fixing plate 150 and squeeze the electronic button, which triggers the function of button 100. When the button body 110 (e.g., the pressing portion 111) is released, the button body 110 (e.g., the pressing portion 111 and the connecting portion 112) will return to its original position under the rebound force of the pressing portion 111 and the connecting portion 112, realizing the rebound of button 100.

[0118] In some embodiments, such as Figure 7BAs shown, the key 100 includes a key body 110, a bushing 120, a shell 130, a support part 140, and a fixing plate 150. At this time, the electronic key on the fixing plate 150 can realize its function by contacting the support part 140 (for example, a cantilever 141 on the support part 140). For example, when the key body 110 (for example, a pressing part 111) is pressed by an external force, the pressing part 111 and a connecting part 112 move towards the support part 140 and press the cantilever 141, and the cantilever 141 will be elastically deformed. With further pressing of the key body 110 (for example, the pressing part 111), the deformation of the cantilever 141 gradually increases, and when the set position point of the cantilever 141 contacts the electronic key, the electronic key triggers the function of the key 100. When the key body 110 (for example, the pressing part 111) is released, the key body 110 (for example, the pressing part 111 and the connecting part 112) will return to the original position under the elastic force of the cantilever 141, realizing the rebound of the key 100.

[0119] Figure 8 is a structural schematic diagram of a key according to some embodiments of the present specification.

[0120] In some embodiments, the assembly process of the key 100 is as follows:

[0121] Step 1: Place the key body 110 into the bushing;

[0122] Step 2: Insert the key body 110 with the bushing 120 into the stepped through hole of the shell 130, and the bushing 120 automatically adjusts its position by deforming the limiting ribs 121 to realize the complete concentricity of the bushing 120, the key body 110, and the stepped through hole of the shell 130;

[0123] Step 3: Place the support part 140 into the bushing 120;

[0124] Step 4: Fix the fixing plate 150 on the shell 130 through the positioning column 131 and the positioning hole 151. At this time, the support part 140 pushes the key body 110 through the cantilever 141. The chamfer structure 113 on the key body 110 and the inclined angle structure 122 inside the bushing realize the fitting under the elastic force of the cantilever 141, and realize the self-adaptive adjustment of the key 100 under the guidance of the chamfer structure 113 and the inclined angle structure 122, further ensuring the concentricity of the bushing 120, the key body 110, and the shell 130, and obtaining the key 100 as shown in Figure 8
