DETAILED DESCRIPTION
[0027] The embodiments of the utility model are described in detail below, the embodiments described with reference to the drawings are exemplary, and the following refers to Figures 1-5 The control device 100 according to the first aspect of the utility model is described.
[0028] As Figures 1-5 shown, the control device 100 according to the first aspect of the utility model comprises: a housing 10, a circuit board 20 and a power supply 30. Specifically, the housing 10 has an accommodating cavity 11, the circuit board 20 is arranged in the accommodating cavity 11, the power supply 30 is arranged in the accommodating cavity 11, and the power supply 30 is located on one side of the circuit board 20 in the up-down direction of the first direction (for example, Figure 1 ).
[0029] Wherein, in the direction from the edge of the housing 10 to the center of the housing 10 in the second direction (for example, Figure 1 the left-right direction), the cross-sectional area of the housing 10 gradually increases; and / or in the direction from the edge of the housing 10 to the center of the housing 10 in the third direction (for example, Figure 1 the front-back direction), the cross-sectional area of the housing 10 gradually increases, and the third direction, the second direction and the first direction are perpendicular to each other. As Figure 1 shown, in the direction from the edge of the housing 10 to the center of the housing 10 in the second direction, the cross-sectional area of the housing 10 gradually increases, and in the direction from the edge of the housing 10 to the center of the housing 10 in the third direction, the cross-sectional area of the housing 10 gradually increases; or only in the direction from the edge of the housing 10 to the center of the housing 10 in the second direction, the cross-sectional area of the housing 10 gradually increases (not shown in the figure); or only in the direction from the edge of the housing 10 to the center of the housing 10 in the third direction, the cross-sectional area of the housing 10 gradually increases (not shown in the figure).
[0030] For example, in Figure 1In the example, the first direction is the thickness direction of the shell 10, the second direction is the length direction of the shell 10, and the third direction is the width direction of the shell 10. Under the premise that the circuit board 20 and the power supply 30 can be completely arranged in the accommodating cavity 11, in the length direction and the width direction, the cross-sectional area in the direction from the edge of the shell 10 to the center of the shell 10 is gradually increased, that is, in the direction from the center of the shell 10 to the edge of the shell 10, the overall thickness of the shell 10 is gradually reduced, thereby reducing the volume of the control device 100 as a whole, making the control device 100 more lightweight, reducing the hand burden of the user during long-term use, and the volume of the control device 100 as a whole is small, facilitating the user to store or carry out, improving the convenience of using the beauty mask. In addition, in this way, the layout of the circuit board 20 and the power supply 30 in the accommodating cavity 11 is more compact, the space in the accommodating cavity 11 is fully utilized, which is beneficial to the lightweight design of the control device 100.
[0031] According to the control device 100 provided in the embodiment of the present application, by gradually increasing the cross-sectional area in the direction from the edge of the shell 10 to the center of the shell 10, the volume of the control device 100 as a whole is reduced, the hand burden of the user during long-term use is reduced, the user is facilitated to store or carry out, the convenience of using the beauty mask is improved, and the lightweight design of the control device 100 is facilitated.
[0032] According to some embodiments of the present application, the shell 10 includes an upper shell 12 and a lower shell 13, the upper shell 12 is arranged on one side of the lower shell 13 in the first direction, the outer surface of the upper shell 12 is a first surface 121, and the outer surface of the lower shell 13 is a second surface 131. Wherein, the distance between the first surface 121 and the connection of the upper shell 12 and the lower shell 13 in the first direction is L1, and the distance between the second surface 131 and the connection of the upper shell 12 and the lower shell 13 in the first direction is L2, wherein L1 and L2 satisfy: L1≤L2.
[0033] As shown in Figure 2 The power supply 30 is arranged close to the lower shell 13, and the circuit board 20 is arranged close to the upper shell 12. Since the upper shell 12 and the lower shell 13 jointly define the accommodating cavity 11, in the first direction, the distance between the second surface 131 and the connection of the upper shell 12 and the lower shell 13 is greater than the distance between the first surface 121 and the connection of the upper shell 12 and the lower shell 13, that is, the volume of the part of the accommodating cavity 11 close to the upper shell 12 is smaller than the volume of the part of the accommodating cavity 11 close to the lower shell 13. Therefore, during installation, the power supply 30 with a larger volume can be arranged close to the lower shell 13, and the relatively flat circuit board 20 can be arranged close to the upper shell 12, and the elements on the circuit board 20 are located between the circuit board 20 and the upper shell 12.
[0034] In this way, the layout of the circuit board 20 and the power supply 30 in the accommodating cavity 11 is more compact, the space in the accommodating cavity 11 is fully utilized, and the lightweight design of the control device 100 is facilitated. Moreover, since the power supply 30 may generate more heat during use, by increasing the volume of the accommodating cavity 11 corresponding to the power supply 30 (i.e. the volume of the part of the accommodating cavity 11 close to the lower shell 13), more space is provided for heat dissipation, which facilitates the heat dissipation efficiency, thereby improving the working reliability of the control device 100 and prolonging the service life of the control device 100.
[0035] In some embodiments, at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the second direction, and / or at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the third direction.
[0036] In some embodiments, at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the second direction, and / or at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the third direction. Figure 2 In some embodiments, at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the second direction, and / or at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the third direction. Figure 3 In some embodiments, at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the second direction, and / or at least one of the first surface 121 and the second surface 131 is an arc surface in the projection plane of the third direction.
[0037] By setting the first surface 121 or the second surface 131 as an arc surface in the projection plane of the second direction or the third direction, that is, the outer side of the control device 100 is approximately an arc structure, when the user holds the control device 100, the arc surface of the control device 100 can be more fitted to the curve of the user's hand, the user can hold the control device 100 more stably, and the user's experience is improved, and the user's hand burden during long-time use is reduced.
[0038] According to some embodiments of the present application, in the projection plane of the second direction, the first surface 121 and the second surface 131 are both arc surfaces, and the radius of curvature of the first surface 121 is greater than the radius of curvature of the second surface 131.
[0039] During use, the user's fingers are placed on the first surface 121 to perform keying and other operations, and by making the radius of curvature of the first surface 121 greater than the radius of curvature of the second surface 131, that is, the first surface 121 is relatively flat, it can be more fitted to the curve of the user's finger part, so that the user's fingers can be more naturally placed on the first surface 121 for subsequent keying and other operations, and the user's finger part burden during long-time use is reduced. In addition, during use, the user's palm is fitted to the second surface 131, and by making the radius of curvature of the first surface 121 greater than the radius of curvature of the second surface 131, that is, the second surface 131 is relatively curved, it can be more fitted to the curve of the user's palm part, and the stability of the user holding the control device 100 is improved.
[0040] Further, as shown in Figure 2 , in the projection plane of the second direction, the radius of curvature of the first surface 121 is R1, and the radius of curvature of the second surface 131 is R2, wherein R1 and R2 satisfy: 28mm≤R1≤32mm, 5.0mm≤R2≤6.0mm.
[0041] When R1<32mm, in the projection plane of the second direction, the radius of curvature of the first surface 121 is too small, that is, the curvature of the first surface 121 is too curved, so that the first surface 121 cannot be closely fitted with the finger part of the user, thereby hindering the user from using the finger to perform subsequent key pressing and other operations, and increasing the burden of the finger part of the user during long-time use; when R1>28mm, in the projection plane of the second direction, the radius of curvature of the first surface 121 is too large, that is, the curvature of the first surface 121 is too flat, and when the user holds the control device 100, the finger part of the user needs to be more forceful to stably hold the control device 100, and the finger part is prone to discomfort and fatigue after long-time use. Therefore, by setting the radius of curvature R1 of the first surface 121 in the projection plane of the second direction to be within the range of 28mm-32mm, the first surface 121 is closely fitted with the finger part of the user, and the user's experience is optimized.
[0042] When R2<6.0mm, in the projection plane of the second direction, the radius of curvature of the second surface 131 is too small, that is, the curvature of the second surface 131 is too curved, and the second surface 131 cannot be closely fitted with the palm of the user, and the palm of the user is subjected to a large compression force during holding, and the palm part is prone to discomfort and fatigue after long-time use; when R2>5.0mm, in the projection plane of the second direction, the radius of curvature of the second surface 131 is too large, that is, the curvature of the second surface 131 is too flat, and the second surface 131 cannot be closely fitted with the palm of the user, and there can be a large gap between the palm of the user and the second surface 131, reducing the stability of the user's holding, and the control device 100 is prone to slipping from the palm of the user, and the palm of the user needs to be more forceful to stably hold the control device 100, and the palm is prone to discomfort and fatigue after long-time use. Therefore, by setting the radius of curvature R2 of the second surface 131 in the projection plane of the second direction to be within the range of 5.0mm-6.0mm, the second surface 131 is closely fitted with the finger part of the user, and the user's experience is optimized.
[0043] According to some embodiments of the present application, in the projection plane of the third direction, the first surface 121 and the second surface 131 are both arc surfaces, and the radius of curvature of the first surface 121 is greater than that of the second surface 131.
[0044] During use, the user's fingers rest on the first surface 121 to perform button presses and other operations. By making the radius of curvature of the first surface 121 greater than that of the second surface 131, meaning the curvature of the first surface 121 is more gradual, it can better conform to the curve of the user's fingers. Therefore, the user's fingers can rest more naturally on the first surface 121 to perform subsequent button presses and other operations, reducing the burden on the user's fingers during prolonged use. Furthermore, during use, the user's palm rests on the second surface 131. By making the radius of curvature of the first surface 121 greater than that of the second surface 131, meaning the curvature of the second surface 131 is more curved, it can better conform to the curve of the user's palm, improving the stability of the user's grip on the control device 100.
[0045] Furthermore, such as Figure 3 As shown, in the projection plane of the third direction, the radius of curvature of the first surface 121 is R3, and the radius of curvature of the second surface 131 is R4, wherein R3 and R4 satisfy: 48mm≤R3≤51mm, 284mm≤R4≤287mm respectively.
[0046] When R3 < 51mm, the radius of curvature of the first surface 121 is too small in the third-direction projection plane, meaning the curvature of the first surface 121 is too curved. This prevents the first surface 121 from fitting snugly against the user's fingers, hindering subsequent button presses and increasing the burden on the user's fingers during prolonged use. When R3 > 48mm, the radius of curvature of the first surface 121 is too large in the third-direction projection plane, meaning the first surface 121 is too flat. When the user holds the control device 100, their fingers need to exert more force to maintain a stable grip, which can easily lead to discomfort and fatigue after prolonged use. Therefore, by setting the radius of curvature R3 of the first surface 121 within the range of 48mm to 51mm in the third-direction projection plane, a snug fit between the first surface 121 and the user's fingers is ensured, while also optimizing the user experience.
[0047] When R4<287mm, in the projection plane of the third direction, the radius of curvature of the second surface 131 is too small, that is, the curvature of the second surface 131 is too curved, the second surface 131 cannot be closely fitted with the palm of the user, and the palm of the user will be subjected to a greater compression force when holding, and the palm part is prone to discomfort and fatigue after long-term use; when R4>284mm, in the projection plane of the third direction, the radius of curvature of the second surface 131 is too large, that is, the curvature of the second surface 131 is too flat, the second surface 131 cannot be closely fitted with the palm of the user, and there can be a large gap between the palm of the user and the second surface 131, reducing the stability of the user's holding, and the control device 100 is prone to falling from the palm of the user, and the palm of the user needs to exert more force to stably hold the control device 100, and the palm is prone to discomfort and fatigue after long-term use. Therefore, by setting the radius of curvature R4 of the second surface 131 in the projection plane of the third direction to be within the range of 284mm-287mm, the second surface 131 is closely fitted with the finger part of the user, and the user's experience is optimized.
[0048] According to some embodiments of the present application, the outer surface of the shell 10 is provided with a plurality of protrusions (not shown in the figure), the plurality of protrusions are spaced apart along the first direction, each protrusion extends along the third direction, the protrusion is a cloth texture structure, and the shape of each protrusion is wave-shaped. The wave-shaped protrusion increases the friction of the surface of the shell 10, and when the user holds the control device 100, the hand contacts the protrusion, which helps the user to better grasp the control device 100, reduces the probability of the control device 100 falling from the user's hand, and improves the stability of holding.
[0049] In some optional embodiments, as shown in Figure 1 The shell 10 is recessed at one end in the first direction towards the center of the shell 10 to form a recessed part 14, and the recessed part 14 is formed with a plug-in interface 141, and the plug-in interface 141 is in communication with the accommodating cavity 11.
[0050] For example, in the example of Figure 1 The recessed part 14 and the plug-in interface 141 both extend along the second direction, the plug-in interface 141 is in communication with the accommodating cavity 11, and the connection line is connected with the circuit board 20 and other components in the accommodating cavity 11. In addition, the setting of the recessed part 14 can prevent foreign matters such as dust from entering the plug-in interface 141 and affecting the components in the accommodating cavity 11, thereby ensuring the working reliability of the control device 100. Moreover, the recessed part 14 ensures the wiring function of the control device 100 while further reducing the overall volume and weight of the control device 100, which is conducive to the lightweight design of the control device 100. In addition, the recessed part 14 is provided on the shell 10, which facilitates the user to identify the position of the plug-in interface 141, and improves the convenience of user operation.
[0051] According to some embodiments of the present application, as shown in Figures 2-5 The control device 100 further comprises a fixing support 40 arranged between the circuit board 20 and the upper shell 12; the upper shell 12 and one of the fixing supports 40 are provided with a plurality of first buckles 122, the upper shell 12 and the other of the fixing supports 40 are formed with a plurality of first clamping grooves 41, each first buckle 122 is clamped and matched with the corresponding first clamping groove 41, and / or the lower shell 13 and one of the fixing supports 40 are provided with a plurality of second buckles 132, the lower shell 13 and the other of the fixing supports 40 are formed with a plurality of second clamping grooves 42, and each second buckle 132 is clamped and matched with the corresponding second clamping groove 42. In the description of the present application, the meaning of "a plurality of" is two or more than two.
[0052] As shown in Figure 2 and Figure 3 The shape of the fixing support 40 is roughly matched with the upper shell 12, the fixing support 40 is arranged between the circuit board 20 and the upper shell 12, which plays a role in supporting and fixing the circuit board 20, avoiding the upper shell 12 directly exerting excessive local pressure on the circuit board 20, and preventing the circuit board 20 from being damaged due to uneven stress.
[0053] The upper shell 12 is provided with a plurality of first buckles 122, and the side of the fixing support 40 adjacent to the upper shell 12 is formed with a plurality of first clamping grooves 41 (as shown in Figure 5 Alternatively, the fixing support 40 is provided with a plurality of first buckles, and the upper shell 12 is formed with a plurality of first clamping grooves (not shown in the figure).
[0054] For example, in the example of Figure 5 The number of first buckles 122 can be six, of which four first buckles 122 are arranged adjacent to the middle part of the upper shell 12, and the above-mentioned four first buckles 122 are respectively arranged on both sides of the width direction of the upper shell 12; the other two first buckles 122 are arranged on both sides of the length direction of the upper shell 12.
[0055] The clamping mode of buckles and clamping grooves is adopted, when installing the upper shell 12 and the fixing support 40, without using additional tools, only by aligning the first buckles 122 with the first clamping grooves 41 and exerting a certain pressure, the connection of the upper shell 12 and the fixing support 40 can be completed. Moreover, when the control device 100 needs to be maintained or overhauled, only by exerting a certain external force, the first buckles 122 can be separated from the first clamping grooves 41, so that the upper shell 12 and the fixing support 40 can be separated, which reduces the difficulty and cost of maintenance. In addition, the structure of buckles and clamping grooves is relatively simple, which reduces the manufacturing difficulty and production cost of the control device 100.
[0056] In addition, the lower shell 13 is provided with a plurality of second buckles 132, and the side of the fixing support 40 adjacent to the lower shell 13 is formed with a plurality of second clamping grooves 42 (as shown in Figure 5 Alternatively, the fixing support 40 is provided with a plurality of second buckles, and the lower shell 13 is formed with a plurality of second clamping grooves (not shown in the figure).
[0057] For example, in the example shown in Figure 5 The number of the second buckles 132 can be four, and along the thickness direction of the lower shell 13, the four second buckles 132 are arranged on the side of the lower shell 13 adjacent to the upper shell 12, of which two second buckles 132 are arranged on one side in the width direction of the lower shell 13, and the other two second buckles 132 are arranged on the other side in the width direction of the lower shell 13, and the two second buckles 132 on the same side in the width direction of the lower shell 13 are arranged in the length direction of the lower shell 13.
[0058] By using the clamping mode of buckles and clamping grooves, when the lower shell 13 and the fixing support 40 are installed, no additional tools are needed, and the connection of the lower shell 13 and the fixing support 40 can be completed by aligning the second buckles 132 with the second clamping grooves 42 and applying a certain pressure. Moreover, when the control device 100 needs to be maintained or repaired, the lower shell 13 and the fixing support 40 can be separated by applying a certain external force to make the second buckles 132 separate from the second clamping grooves 42, which reduces the difficulty and cost of maintenance. In addition, the buckle and clamping groove structure is relatively simple, which reduces the manufacturing difficulty and production cost of the control device 100.
[0059] In some optional embodiments, part of the upper shell 12 in the thickness direction of the upper shell 12 is recessed towards the lower shell 13 to form a pressing part 123, and the side of the pressing part 123 adjacent to the lower shell 13 is provided with a pressing column 50, and the pressing column 50 is adapted to pass through the fixing support 40 and be opposite to the touch control 21 on the circuit board 20.
[0060] As shown in Figure 3 and Figure 4 The pressing part 123 is recessed on the top surface of the upper shell 12, the pressing part 123 is arranged adjacent to the middle part of the upper shell 12, the circuit board 20 is arranged adjacent to the upper shell 12 in the accommodating cavity 11, the pressing column 50 is arranged between the pressing part 123 and the touch control 21, and the pressing column 50 extends along the thickness direction of the upper shell 12, the fixing support 40 is provided with a passage 43 adapted for the pressing column 50 to pass through, the passage 43 extends along the thickness direction of the fixing support 40, and the pressing column 50 passes through the passage 43 and is opposite to the touch control 21.
[0061] Since the pressing portion 123 is concave on the top surface of the upper shell 12, the pressing portion 123 has a different touch feeling from other parts of the upper shell 12, and the area ratio of the pressing portion 123 on the upper shell 12 is large, so it is easy to distinguish. When the user needs to operate the beauty mask, even in the case of limited vision, the user can locate the position of the pressing portion 123 on the upper shell 12 by touch, press the pressing portion 123 downward, the upper shell 12 drives the pressing column 50 to move downward, the pressing column 50 applies force to the touch control 21, and the circuit of the circuit board 20 is connected under the action of the touch control 21. When the circuit of the circuit board 20 is connected, the user stops pressing, the touch control 21 restores, the pressing column 50 is lifted upward, and the pressing column 50 and the upper shell 12 are reset. In this way, quick operation can be realized in the case of limited vision of the user, the convenience and accuracy of operation are improved, the probability of operation error is reduced, and the user experience is improved.
[0062] Moreover, the shape of the pressing portion 123 is convenient for the user to identify during operation, and the upper shell 12 as a whole functions as a key, preventing the problem of accidental touch caused by too many keys and small structure, further reducing the probability of operation error and improving the user experience.
[0063] In addition, the channel 43 on the fixed support 40 provides a guiding effect for the pressing column 50, so that the pressing column 50 can accurately move up and down along the channel 43, contact the touch control 21 and apply pressure to the touch control 21, ensuring that the circuit can be connected, improving the accuracy and reliability of the pressing operation.
[0064] It should be noted that the touch control 21 can be made of rubber material, which can be selected by those skilled in the art according to actual needs, and the present application does not make specific limitations here.
[0065] Further, the touch control 21 includes a touch portion 211 extending along the length direction of the touch control 21, the touch portion 211 is connected with the pressing column 50, the touch portion 211 includes a first elastic section 2111, a second elastic section 2112 and a third elastic section 2113 connected with each other, the second elastic section 2112 is connected between the first elastic section 2111 and the third elastic section 2113, the first elastic section 2111 is connected with the pressing column 50, and the third elastic section 2113 extends in the direction towards the circuit board 20 and abuts against the circuit board 20.
[0066] In this way, when the user performs the pressing operation, the force of the pressing column 50 is sequentially transmitted to the first elastic section 2111 and the second elastic section 2112, the second elastic section 2112 is deformed and drives the first elastic section 2111 to move along the length direction of the pressing column 50, so as to realize the connection or disconnection of the circuit of the circuit board 20, and the third elastic section 2113 supports the first elastic section 2111 and the second elastic section 2112.
[0067] Therefore, when the user presses, the second elastic section 2112 is deformed to bring the user tactile feedback, and the user can judge whether the pressing operation is effective and the pressing force is appropriate through the touch, thereby improving the experience and accuracy of the user operation. Moreover, the structure of the touch part 211 can absorb and buffer part of the external force, thereby avoiding the damage or failure of the circuit board 20 caused by the force directly acting on the circuit board 20, improving the working reliability of the control device 100 as a whole, and prolonging the service life of the device as a whole.
[0068] In some optional embodiments, as shown in Figure 4 The control device 100 further comprises at least one elastic member 60, the elastic member 60 is sleeved on the pressing column 50, and the elastic member 60 is located on the side of the pressing column 50 away from the touch part 21 in the length direction.
[0069] When the pressing column 50 moves to the appropriate position, the elastic member 60 abuts against the bottom wall of the channel 43 and gives the user tactile feedback, and the user can judge whether the pressing is in place through the touch, and when the external force on the pressing column 50 disappears, the elastic member 60 can provide a reverse elastic force to reset the pressing column 50. Meanwhile, the elastic member 60 can buffer the impact force of the pressing in the pressing process, thereby avoiding damage to the pressing column 50 and other components. In addition, the elastic member 60 can limit the lateral movement of the pressing column 50 in the channel 43, thereby improving the position stability of the pressing column 50 in the pressing process, and improving the working reliability of the control device 100.
[0070] It should be noted that the elastic member 60 can be made of rubber material, and those skilled in the art can select according to actual needs, which is not limited in the embodiment of the application.
