In this solution, one end of the elastic portion facing away from the connecting portion is connected to one side of the button along the second direction, and the force arm for pressing is longer than when the elastic portion is connected to the side of the button close to the connecting portion.

Compared with the elastic part being directly connected to one end of the key close to the connection part, when the key in this solution is subjected to pressure along the third direction (the third direction is parallel to the axis of the through hole and perpendicular to the first direction), the rotation of the key around the connection between the elastic part and the connection part is decomposed by the transition part and the deformation part into displacement along the second direction and displacement along the first direction, so that the probability of the key set in the through hole rubbing against the inner wall of the through hole during the pressing process is reduced, thereby making the key pressing process smoother.

At the same time, multiple buttons are fixed to the camera monitor through the connecting part, which reduces the probability of buttons falling off when installing other structural parts, and reduces the difficulty of assembling the camera monitor.

[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] The utility model provides a button assembly 100 that can be used for a photographic monitor 10. The button assembly 100 can also be used for other devices that require buttons. Figures 1 to 10 The button assembly 100 includes a connecting portion 110, a plurality of elastic portions 120, and a plurality of keys 130. The button assembly 100 can be manufactured by an integrated molding method. For example, the button assembly 100 can be manufactured by injection molding, or by machining. The structural shape of the connecting portion 110 includes but is not limited to a cuboid, and the material used in the connecting portion 110 includes but is not limited to plastic, aluminum alloy, etc. The shape of the key 130 includes but is not limited to a rectangular key 130, a circular key 130, an elliptical key 130, and an irregularly shaped key 130, etc. The material used in the key 130 includes but is not limited to plastic, polymer, and aluminum alloy, etc. The material used in the key 130 can be the same as the material used in the connecting portion 110, or it can be different from the material used in the connecting portion 110. The material used in the elastic portion 120 can be the same as the material used in the key 130 or the same as the material used in the connecting portion 110, and the elastic portion 120 is configured to be elastically deformed when subjected to force.

[0060] In one embodiment, the number of the elastic parts 120 and the number of the buttons 130 may be the same, and each button 130 is arranged on one side of the connecting part 110 along the first direction X, and each button 130 is arranged at intervals along the second direction Y, and the second direction Y intersects with the first direction X (the second direction Y may be a direction perpendicular to the first direction X). One end of each elastic part 120 is connected to each button 130, and the other end is connected to the connecting part 110, so that each button 130 can form a whole with the connecting part 110. Compared with the related art in which each button 130 is independently installed on other equipment (such as the camera monitor 10), the present application integrates multiple buttons 130 into a button assembly 100 through the connecting part 110. In the process of assembling the camera monitor 10, the present application can reduce the probability of the previously installed button 130 falling off due to shaking or vibration when assembling other structural parts, and effectively reduces the installation efficiency of the button 130. Among them, one end of the elastic part 120 away from the connecting part 110 is connected to the side of the button 130 along the second direction Y. Therefore, compared with the elastic part 120 connected to the side of the button 130 close to the connecting part 110, the design of the elastic part 120 connected to the side of the button 130 along the second direction Y makes the force arm of the button 130 longer, the force required to press the button 130 is smaller, and the pressing process is lighter, thereby improving the pressing feel. In one embodiment, the end of the elastic part 120 away from the connecting part 110 can also be connected to the end of the button 130 away from the connecting part 110.

[0061] In another embodiment, the number of the elastic parts 120 and the number of the buttons 130 may be different. Specifically, one end of the elastic part 120 is connected to the connecting part 110, and the other end has two opposite end surfaces extending along the second direction Y, and each end surface is connected to one side of each button 130 along the second direction Y. When the button assembly 100 is manufactured in an integrated molding manner, the design of one elastic part 120 connecting two or more buttons 130 is conducive to reducing mold costs and saving material costs.

[0062] See also Fig. 9For ease of description, the button assembly 100 is defined to include a first key group 140 and a second key group 150 arranged adjacently along the second direction Y, the first key group 140 includes a first key 141 and a first elastic portion 142, the second key group 150 includes a second key 151 and a second elastic portion 152, and the first elastic portion 142 and the second elastic portion 152 are disposed between the first key 141 and the second key 151. Specifically, the first elastic portion 142 includes a first adapter portion 1421 and a first deformation portion 1422, the first adapter portion 1421 extends along the second direction Y, and one side of the first key 141 along the second direction Y is connected to one end of the first adapter portion 1421 along the second direction Y, one end of the first deformation portion 1422 away from the adapter portion 121 is connected to one end of the first adapter portion 1421 away from the first key 141, and one end of the first deformation portion 1422 away from the first key 141 is connected to the connection portion 110. The second elastic portion 152 includes a second adapter portion 1521 and a second deformation portion 1522. The second adapter portion 1521 extends along the second direction Y. One side of the second button 151 along the second direction Y is connected to one end of the second adapter portion 1521 along the second direction Y. One end of the second deformation portion 1522 away from the connecting portion 110 is connected to one end of the second adapter portion 1521 away from the second button 151. One end of the second deformation portion 1522 away from the second button 151 is connected to the connecting portion 110. One end of the first adapter portion 1421 away from the first button 141 is adjacent to one end of the second adapter portion 1521 away from the second button 151, and the first deformation portion 1422 and the second deformation portion 1522 are located between the first button 141 and the second button 151. In order to improve the service life of the button assembly 100, a reinforcement structure can be provided at the connection between the first elastic part 142 and the connecting part 110, and at the connection between the second elastic part 152 and the connecting part 110. The specific embodiment of the reinforcement structure includes but is not limited to the local thickening at the connection between the connecting part 110 and the first elastic part 142 and the second elastic part 152. Therefore, the first deformation part 1422 and the second deformation part 1522 are arranged adjacent to each other between the first button 141 and the second button 151, which is helpful for the design and manufacture of the reinforcement structure. It should be noted that the first button 141 and the second button 151 are no different from the above-mentioned button 130. Similarly, the first elastic part 142 and the second elastic part 152 are no different from the above-mentioned elastic part 120. The "first" and "second" defined here are only set for the convenience of description.

[0063] To reduce the manufacturing difficulty of the button assembly 100, in some embodiments, refer to Fig. 9The elastic portion 120 includes a transition portion 121 and a deformation portion 122. The extension direction of the transition portion 121 is parallel to the second direction Y. One end of the deformation portion 122 is connected to the transition portion 121 and the other end is connected to the connection portion 110. The extension direction of the deformation portion 122 is perpendicular to the second direction Y and parallel to the first direction X. That is, the shape of the deformation portion 122 can be a straight rod, and the shape of the transition portion 121 can also be a straight rod, so as to facilitate the injection molding (or machining molding, etc.) of the button assembly 100. The thickness of the deformation portion 122 can be the same as the thickness of the transition portion 121, or the thickness of the deformation portion 122 can be different from the thickness of the transition portion 121. In one embodiment, the extension direction of the deformation portion 122 can be perpendicular to the extension direction of the transition portion 121, that is, the first direction X is perpendicular to the second direction Y. In another embodiment, the extension direction of the deformation portion 122 may cross the extension direction of the adapter portion 121 , and the extension direction of the deformation portion 122 is not perpendicular to the extension direction of the adapter portion 121 .

[0064] In addition, the connection between the deformation part 122 and the connection part 110 has a rounded corner. In the case where the button assembly 100 is molded by injection molding, the setting of the rounded corner is conducive to the production and manufacturing of the mold, and is also conducive to the demolding of the button assembly 100. In addition, when the button 130 is pressed, the pressure acting on the button 130 is transmitted to the deformation part 122 through the adapter 121, so that when the deformation part 122 is elastically deformed, the stress at the connection between the deformation part 122 and the connection part 110 increases, and the rounded corner is set at the connection between the deformation part 122 and the connection part 110, which can improve the fatigue resistance of the connection between the deformation part 122 and the connection part 110, thereby improving the service life of the button assembly 100.

[0065] See also Fig.10In one embodiment, the elastic portion 120 includes a transition portion 121 and a deformation portion 122. The extension direction of the transition portion 121 is parallel to the second direction Y, and the shape of the deformation portion 122 is configured as an arc, and the deformation portion 122 is arranged around the circumference of the key 130. One end of the deformation portion 122 along the first direction X is connected to the transition portion 121, and the other end is connected to the connection portion 110. Regarding the shape of the deformation portion 122 being configured as an arc, it should be noted that the shape of a part of a circle, a part of an ellipse, and the shape of the deformation portion 122 extending along a curve so that the deformation portion 122 appears to have a partial circular arc or a partial elliptical arc can all be considered to be an arc. The shape of the deformation portion 122 is configured as an arc, and the arc is arranged around the circumference of the key 130, which reduces the probability that the key 130 is interfered by the elastic portion 120 during the pressed movement. Furthermore, the arc-shaped structure of the deformation portion 122 can also reduce the minimum distance between the end of the button 130 close to the connecting portion 110 and the connecting portion 110, which is beneficial to improving the structural compactness of the button assembly 100 and reducing the volume of the button assembly 100. In one embodiment, the shape of the deformation portion 122 is configured as a 1 / 4 circle arc to reduce the difficulty of manufacturing the button assembly 100.

[0066] For ease of description, the button assembly 100 is defined as having a first state and a second state, and the shape of the deformation portion 122 is configured as an arc. When the deformation portion 122 is compressed, the button assembly 100 is in the first state, otherwise the button assembly 100 is in the second state. When the button assembly 100 is in the first state, the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 is D, and when the button assembly 100 is in the second state, the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 is H. Among them, the minimum distance D from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 and the minimum distance H from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 satisfy: D / H=1 / 1.3. Specifically, when the button 130 is subjected to pressure in a direction from the button 130 to the connecting portion 110 (the direction is parallel to the first direction X), the button assembly 100 changes from the second state to the first state, and the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 gradually decreases. When the pressure in the direction from the button 130 to the connecting portion 110 is removed, the button assembly 100 changes from the first state to the second state, and the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 gradually increases until the deformation portion 122 returns to the initial state. The elastic deformation ability of the deformation portion 122 enables the button 130 to move in a direction close to the connecting portion 110 within the elastic deformation range of the deformation portion 122, which helps to reduce the probability of the button assembly 100 being damaged during transportation.

[0067] In another embodiment, the extension direction of the deformation portion 122 is parallel to the first direction X, the shape of the adapter portion 121 is configured to be arc-shaped, and the adapter portion 121 is configured to be able to produce elastic deformation under force. When the button 130 is subjected to pressure in the direction from the button 130 to the connecting portion 110 (the direction is parallel to the first direction X), the adapter portion 121 is subjected to force and elastic deformation occurs, so that the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 gradually decreases. When the pressure in the direction from the button 130 to the connecting portion 110 is removed, the adapter portion 121 has a tendency to restore the initial state, so that the minimum distance from the end of the button 130 close to the connecting portion 110 to the connecting portion 110 gradually increases until the adapter portion 121 restores the initial state.

[0068] The second aspect of the present invention provides a photographic monitor 10, see Figures 1 to 8 The camera monitor 10 includes the button assembly 100 described in any one of the above-mentioned embodiments or examples. The camera monitor 10 also includes a housing 200, which includes a bottom plate 210 and a frame 220. The bottom plate 210 and the frame 220 together define a receiving cavity 230 with an opening at one end. The frame 220 includes a frame 221 provided with a through hole 2211, and the through hole 2211 communicates with the receiving cavity 230. The button assembly 100 is arranged in the receiving cavity 230, and the button 130 is passed through the through hole 2211. The housing 200 can be formed by injection molding or by machining. The bottom plate 210 and the frame 220 can be made in an integral molding manner, or the bottom plate 210 and the frame 220 can be made separately and then assembled. The number of buttons 130 is the same as the number of through holes 2211. The frame 220 may include a plurality of frames 221 , and the through hole 2211 may be disposed in any one of the frames 221 or in a plurality of the frames 221 . The number and position of the through hole 2211 may be determined in combination with specific design requirements of the photographic monitor 10 .

[0069] It should be noted that the camera monitor 10 further includes components such as a circuit board 300 and a key switch 400. The key switch 400 is electrically connected to the circuit board 300, and both the circuit board 300 and the key switch 400 are disposed in the accommodating cavity 230.

The clamping tooth 1112 is provided on the side of the clamping member 1111 away from the connecting portion 110 along the third direction Z, and the clamping tooth 1112 extends along the second direction Y.

[0071] A plurality of positioning members 222 may be provided on the side of the frame 221 close to the accommodating cavity 230, and a plurality of fixing members 111 may be provided on the connecting portion 110. The number of fixing members 111 may be the same as or different from the number of positioning members 222. The number of positioning members 222 may be greater than the number of fixing members 111, and the positioning members 222 may play a role in reinforcing the structure of the frame 221. In one embodiment, two fixing members 111 are provided on the side of the connecting portion 110 close to the accommodating cavity 230. For ease of description, the connecting portion 110 is defined to include a first fixing member 111 and a second fixing member 111. The first fixing member 111 includes a first engaging tooth 1112, and the second fixing member 111 includes a second engaging tooth 1112. In one embodiment, the first engaging tooth 1112 extends along the second direction Y toward a direction close to the second fixing member 111, and the second engaging tooth 1112 extends along the second direction Y toward a direction close to the first fixing member 111. In another embodiment, the first engaging tooth 1112 extends along the second direction Y in a direction away from the second fixing member 111 , and the second engaging tooth 1112 extends along the second direction Y in a direction away from the first fixing member 111 .

[0072] It should be noted that the button 130 has a limiting extension on its circumference. When the button 130 is inserted into the through hole 2211 along the third direction Z, the limiting extension can abut against the side of the frame 221 close to the accommodating cavity 230, thereby limiting the position of the button 130 relative to the through hole 2211. After the button assembly 100 is installed in the frame 221, its degree of freedom along the first direction X and along the second direction Y is limited by the through hole 2211, and the degree of freedom of the button along the third direction Z is limited by the positioning member 222. The arrangement of the positioning member 222 and the fixing member 111 improves the stability of the button assembly 100 installed in the housing 200, while improving the installation efficiency of the button 130, and effectively reduces the probability of shaking or vibration of other structural parts during the assembly process in the housing 200, causing the button 130 to be separated from the housing 200, thereby reducing the difficulty of assembling the camera monitor 10.

[0073] In another embodiment, see Figure 4 and Figure 6 A mounting rib 211 is provided on one side of the bottom plate 210 close to the accommodating cavity 230, and the mounting rib 211 protrudes from the bottom plate 210 along the first direction X. A groove 112 is provided on one side of the connecting portion 110 away from the frame 221 along the third direction Z, and the groove 112 is recessed toward the frame 221 along the third direction Z. When the button 130 is inserted into the through hole 2211, the side of the mounting rib 211 close to the frame 221 is connected to the groove 112, thereby improving the stability of the button assembly 100 installed on the housing 200. It should be noted that the deformation portion 122 (or the adapter portion 121) is configured as an arc structure with elastic deformation. When the button assembly 100 moves along the third direction Z in the accommodating cavity 230 toward the direction close to the through hole 2211 so that the button 130 is inserted into the through hole 2211, the mounting rib 211 protruding along the first direction X can apply a force to the connecting portion 110 in the direction from the connecting portion 110 to the button 130, so that the deformation portion 122 (or the adapter portion 121) is elastically deformed, and the connecting portion 110 moves toward the direction close to the button 130 to avoid the mounting rib 211.

[0074] After the button 130 is inserted into the through hole 2211, the force applied by the mounting rib 211 to the connecting portion 110 along the first direction X disappears, and the deformed portion 122 (or the adapter portion 121) has a tendency to recover to its initial state, so the connecting portion 110 moves along the first direction X toward the direction close to the bottom plate 210 under the recovery tendency of the deformed portion 122 (or the adapter portion 121) until the deformed portion 122 (or the adapter portion 121) recovers to its initial state. During the movement of the connecting portion 110 along the first direction X toward the direction close to the bottom plate 210, the side of the mounting rib 211 close to the frame 221 can be snapped into the groove 112, thereby guiding the movement of the connecting portion 110. When the button 130 and the connecting portion 110 are installed in place, the cooperation between the mounting rib 211 and the groove 112 can limit the freedom of the button assembly 100 along the third direction Z and the second direction Y, and the through hole 2211 can limit the freedom of the button assembly 100 along the first direction X and the second direction Y. Therefore, the present application improves the stability of the button assembly 100 installed on the photographic monitor 10, and effectively reduces the probability of shaking or vibrating other structural parts during the assembly process on the shell 200, causing the button 130 to detach from the shell 200.

[0075] To facilitate the installation of the button assembly 100, in one embodiment, the installation rib 211 has an inclined surface on the side away from the frame 221 along the third direction Z, and the inclined surface is inclined toward the direction close to the frame 221. When the button assembly 100 moves in the accommodating cavity 230 along the third direction Z toward the direction close to the through hole 2211, the inclined surface can apply a gradually increasing pressure to the connecting portion 110, so that the deformation portion 122 (or the adapter portion 121) can be gradually deformed, reducing the risk of the deformation portion 122 (or the adapter portion 121) being damaged.

[0076] It should be noted that, in order to facilitate the connection part 110 to effectively avoid the installation rib 211 and enable the groove 112 to be clamped on the installation rib 211, the size of the installation rib 211 along the first direction X is lower than the elastic deformation range of the deformation part 122 (or the adapter part 121). Exemplarily, when the button 130 is subjected to pressure from the direction of the button 130 to the connection part 110 (the direction is parallel to the first direction X), the deformation part 122 is elastically deformed, so that the minimum distance from the end of the button 130 close to the connection part 110 to the connection part 110 is 1 unit. When the pressure along the direction from the button 130 to the connection part 110 is removed, the deformation part 122 has a tendency to restore the initial state, and finally makes the minimum distance from the end of the button 130 close to the connection part 110 to the connection part 110 be 1.3 units. Therefore, the size of the installation rib 211 along the first direction X can be 0.65 to 0.8 units.

[0077] In another embodiment, the frame 221 is provided with a positioning member 222, and the bottom plate 210 is provided with a mounting rib 211, and the connecting portion 110 is provided with both a fixing member 111 and a groove 112. The fixing member 111 is located on a side of the connecting portion 110 close to the frame 221, and the fixing member 111 protrudes from the connecting portion 110 along the third direction Z. The groove 112 is provided on a side of the connecting portion 110 away from the frame 221 along the third direction Z, and the groove 112 is recessed toward the frame 221 along the third direction Z. The button assembly 100 moves in the accommodating cavity 230 along the third direction Z toward the direction close to the through hole 2211 until the button 130 is inserted into the through hole 2211, the positioning member 222 is engaged with the fixing member 111, and the mounting rib 211 is engaged with the groove 112, thereby further improving the stability of the button assembly 100 installed on the photographic monitor 10.
