Description

Technical Field

[0001] The embodiments of the present utility model relate to the field of electronic technologies, and particularly to a touch device. Background Art

[0002] Many existing touch devices are provided with passive infrared sensors for sensing whether someone is approaching. When the passive infrared sensor senses that someone is approaching, the screen can be automatically awakened.

[0003] Please refer to Figure 1 and Figure 2 , in the existing touch device 100’, the passive infrared sensor is generally arranged inside the housing 1’. A through hole 11’ is arranged at the front end of the housing 1’. The passive infrared sensor can pass through the through hole 11’ to sense whether there is anyone in front of the touch device 100’.

[0004] During the implementation of the embodiments of the present utility model, the inventor found that: in order to facilitate the user to view the screen 2’, the touch device 100’ usually needs to be placed obliquely on the desktop. As Figure 2 shown Figure 2 , the dotted line in represents the boundary of the sensing area of the passive infrared sensor. At this time, the passive infrared sensor is easily blocked by the desktop H’ and thus cannot sense the human body in front of the desktop H’, affecting the user experience.

[0005] The main technical problem to be solved by the embodiments of the present utility model is to provide a touch device, which can reduce the blockage of the desktop to the infrared sensor when the touch device is placed obliquely on the desktop, and is beneficial to improving the accuracy of the infrared sensor in sensing the human body.

[0006] To solve the above technical problems, a technical solution adopted in an embodiment of the present utility model is: to provide a touch device, including a housing, a screen, a circuit board, a lens, and an infrared sensor. The housing includes a rear case and a cover body. The rear case is provided with a receiving cavity and a through hole. The through hole communicates with the receiving cavity. The cover body covers the receiving cavity. The screen is disposed on the surface of the cover body facing away from the rear case. The circuit board is received in the receiving cavity and is electrically connected to the screen. The lens covers the through hole. The infrared sensor is received in the receiving cavity and is electrically connected to the circuit board. Along a first direction, at least part of the projection of the infrared sensor is located within the through hole. The axis of the through hole is parallel to the outer surface of the screen. In a second direction, there is a height difference between the center of the infrared sensor and the axis of the through hole with respect to a first plane, where the first plane coincides with the outer surface of the screen, the first direction is parallel to the axis of the through hole, and the second direction is perpendicular to the outer surface of the screen. In this embodiment, by providing a receiving cavity and a through hole in the rear case, the through hole communicates with the receiving cavity, the lens covers the through hole, the infrared sensor is received in the receiving cavity, and along the first direction, at least part of the projection of the infrared sensor is located within the through hole, so that the infrared sensor can pass through the through hole to sense whether there is a human body in front of the through hole. In the second direction, there is a height difference between the center of the infrared sensor and the axis of the through hole with respect to the first plane, the first plane coincides with the outer surface of the screen, and the axis of the through hole is parallel to the outer surface of the screen, so that the sensing direction of the infrared sensor is offset towards the plane where the outer surface of the screen is located. Thus, when the touch device is placed obliquely on a table, the blocking of the table on the infrared sensor can be reduced, which is beneficial to improving the accuracy of the infrared sensor in sensing a human body and enhancing the user experience.

[0007] In some embodiments, in the second direction, the distance between the center of the infrared sensor and the first plane is greater than the distance between the axis of the through hole and the first plane. With such a setting, when the touch device is placed obliquely on a table, the blocking of the table on the infrared sensor can be reduced, and thus the accuracy of the infrared sensor in sensing a human body can be improved, enhancing the user experience.

[0008] In some embodiments, the touch device further includes a mounting bracket. The mounting bracket is disposed in the receiving cavity, fixed to the rear case, and along the first direction of observation, at least part of the projection of the mounting bracket is located within the through hole. The infrared sensor is disposed on the mounting bracket. In this embodiment, by providing the mounting bracket, it is convenient to make the distance between the center of the infrared sensor and the first plane greater than the distance between the axis of the through hole and the first plane, facilitating the installation of the infrared sensor.

[0009] In some embodiments, the touch device further includes a support assembly. The support assembly is connected to one end of the rear case away from the via hole. The support assembly can rotate relative to the rear case about a first axis. The support assembly is located on the side of the rear case facing away from the screen. Wherein, the first axis is parallel to the outer surface of the screen; when the support assembly is in the first position, the touch device can be placed flat on the table, and when the support assembly is in the second position, the touch device can be placed obliquely on the table. In this embodiment, by providing the support assembly, the support member can support the touch device to be placed obliquely, which can facilitate the user to observe the screen and improve the user experience.

[0010] In some embodiments, the support assembly includes a support frame and a first rotating hinge. The first rotating hinge is fixed to one end of the rear case away from the via hole. One end of the support frame is connected to the first rotating hinge. The first axis passes through the first rotating hinge so that the support frame can rotate relative to the rear case about the first axis. In this embodiment, by providing the first rotating hinge and connecting the support frame to the first rotating hinge, the support frame can rotate relative to the rear case about the first axis, so that the touch device can be switched between being placed flat and being placed obliquely.

[0011] In some embodiments, the first rotating hinge includes a first fixing member and a first rotating member. The first fixing member is provided with a first rotating hole. The first fixing member is fixed to the rear case. A part of the first rotating member is inserted into the first rotating hole. One end of the support frame is connected to the part of the first rotating member protruding from the first rotating hole. The first rotating member can rotate relative to the first rotating hole. Wherein, the axis of the first rotating hole coincides with the first axis.

[0012] In some embodiments, the first rotating hinge further includes a second rotating member. A part of the second rotating member is inserted into the first rotating hole. The second rotating member can rotate relative to the first rotating hole. The second rotating member and the first rotating member are respectively located at both ends of the first rotating hole. The support frame is also connected to the part of the second rotating member protruding from the first rotating hole. In this embodiment, by providing the second rotating member, the second rotating member can rotate relative to the first rotating hole, which can improve the smoothness of the rotation process of the support frame. In addition, both the first rotating member and the second rotating member have friction with the inner wall of the first rotating hole. Therefore, by providing the second rotating member, the friction can be increased, thereby improving the stability of the support of the support frame for the touch device.

[0013] In some embodiments, the support assembly further includes a second rotating hinge. The second rotating hinge is fixed to the side of the rear case facing away from the screen. Along the third direction, the second rotating hinge and the first rotating hinge are opposite to each other. The support frame is connected to the second rotating hinge. The third direction is perpendicular to the first direction and the second direction respectively. In this embodiment, by providing the second rotating hinge and connecting the support frame to the second rotating hinge, the stability of the rotation of the support frame can be improved. Moreover, since the two ends of the support frame are respectively connected to the first rotating hinge and the second rotating hinge, the stability of the support of the support frame for the touch device can be improved.

[0014] In some embodiments, a receiving groove is provided on the side of the rear case facing away from the screen, and the support frame can be received in the receiving groove.

[0015] In some embodiments, the touch device further includes a plurality of feet, and the plurality of feet are all provided on the side of the rear case facing away from the screen.

[0016] In some embodiments, the touch device further includes a heat dissipation component. The heat dissipation component is received in the accommodation cavity and is connected to the circuit board to dissipate heat from the circuit board. In this embodiment, by providing the heat dissipation component to dissipate the heat in the circuit board, it is beneficial to improve the heat dissipation efficiency of the circuit board and reduce the risk that the circuit board overheats and affects the normal operation of the circuit board.

[0017] The beneficial effects of the embodiments of the present utility model are as follows: Different from the prior art, in the embodiments of the present utility model, by providing an accommodation cavity and a through hole in the rear case, the through hole communicates with the accommodation cavity, the lens covers the through hole, the infrared sensor is received in the accommodation cavity, and along the first direction, at least part of the projection of the infrared sensor is located in the through hole, so that the infrared sensor can pass through the through hole to sense whether there is a human body in front of the through hole. In the second direction, there is a height difference between the center of the infrared sensor and the axis of the through hole with respect to the first plane, the first plane coincides with the outer surface of the screen, and the axis of the through hole is parallel to the outer surface of the screen, so that the sensing direction of the infrared sensor is offset toward the plane where the outer surface of the screen is located. Therefore, when the touch device is placed obliquely on the desktop, the blockage of the desktop to the infrared sensor can be reduced, which is beneficial to improving the accuracy of the infrared sensor in sensing the human body and enhancing the user experience.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Many existing touch devices are equipped with passive infrared sensors, especially in conference rooms or classrooms. The passive infrared sensors in touch devices are used to sense whether someone is approaching. When the passive infrared sensor senses someone approaching, the screen can be automatically awakened so that the user can directly control the touch device.

[0033] See also Figure 1 and Figure 2 The passive infrared sensor in the existing touch device 100' is generally arranged inside the housing 1', and a through hole 11' is arranged at the front end of the housing 1'. The passive infrared sensor can sense whether there is a person in front of the touch device 100' through the through hole 11'. However, in some application scenarios, such as classrooms or conference rooms, it is often necessary to place the touch device 100' at an angle, such as Figure 2 As shown, teachers or conference speakers can better observe and operate the touch device 100'. The inventors found that when the touch device 100' is tilted, the passive infrared sensor is easily blocked by the edge of the desktop H' and cannot sense the human body approaching, which brings a bad experience to the user.

[0034] In order to solve the above problems, the present application provides a touch device. By making the center of the infrared sensor be located on the side of the first plane away from the screen, when the touch device is tilted, the obstruction of the infrared sensor by the desktop H can be reduced. The specific structure and function of the touch device of the present application are described in detail below.

[0035] See also Figures 3 to 5, the touch device 100 includes a housing 1, a screen 2, a circuit board 3, a lens 4, and an infrared sensor 5. The housing 1 includes a rear case 11 and a cover 12. The rear case 11 is provided with a receiving cavity 111 and a through hole 112. The through hole 112 communicates with the receiving cavity 111. The cover 12 covers the receiving cavity 111. The screen 2 is disposed on the surface of the cover 12 facing away from the rear case 11. The screen 2 is used to display a picture and can be touched by a user to control the touch device 100. The circuit board 3 and the infrared sensor 5 are both received in the receiving cavity 111. The circuit board 3 is electrically connected to the infrared sensor 5. The circuit board 3 is also electrically connected to the screen 2. The lens 4 is disposed in the through hole 112, and the lens 4 covers one end of the through hole 112 away from the receiving cavity 111. The infrared sensor 5 is located on the side of the through hole 112 facing the receiving cavity 111. And along the first direction X, at least a part of the projection of the infrared sensor 5 is located in the through hole 112, so that the infrared sensor 5 can sense whether there is anyone approaching the through hole 112 of the touch device 100 through the through hole 112 and the lens 4. Wherein, the first direction X is parallel to the axis N of the through hole 112. In the second direction Y, the center of the infrared sensor 5 and the axis N of the through hole 112 have a height difference relative to a first plane (not labeled). That is to say, the distance between the center of the infrared sensor 5 and the first plane is different from the distance between the axis N of the through hole 112 and the first plane. Wherein, the second direction Y is perpendicular to the outer surface 21 of the screen 2. The first plane coincides with the outer surface 21 of the screen 2. And the axis N of the through hole 112 is parallel to the first plane. In this embodiment, by making the distance between the center of the infrared sensor 5 and the first plane different from the distance between the axis N of the through hole 112 and the first plane, the sensing area of the infrared sensor 5 can be offset toward the plane where the outer surface 21 of the screen 2 is located. That is to say, the sensing area of the infrared sensor 5 is tilted upward relative to the tabletop H. When the touch device 100 is tilted, this can reduce the blockage of the sensing of the infrared sensor 5 by the tabletop H, which is beneficial to improving the accuracy of the infrared sensor 5 in sensing the human body.

[0036] It should be noted that the so-called center of the infrared sensor 5 is the geometric center of the infrared sensor 5.

[0037] In some embodiments, in the second direction Y, the distance between the center of the infrared sensor 5 and the first plane is greater than the distance between the axis N of the through hole 112 and the first plane. With such a setting, the sensing area of the infrared sensor 5 can be tilted upward relative to the tabletop H. When the touch device 100 is tilted relative to the tabletop H, the blockage of the sensing of the infrared sensor 5 by the tabletop H can be reduced, which is beneficial to improving the accuracy of the infrared sensor 5 in sensing the human body.

[0038] In some embodiments, please refer to Figure 4In the second direction Y, the distance between the center of the infrared sensor 5 and the axis N of the through hole 112 is L, and L satisfies: 2.0 mm≤L≤3.0 mm.

[0039] Further, in the second direction Y, the distance L between the center of the infrared sensor 5 and the axis N of the through hole 112 is 2.5 mm.

[0040] In some embodiments, see Figure 4 The touch device 100 includes a mounting frame 6, which is received in the accommodating cavity 111, and is fixed to the rear housing 11. When viewed along the first direction X, at least a portion of the projection of the mounting frame 6 is located in the through hole 112, and the infrared sensor 5 is disposed on the mounting frame 6. In this embodiment, by providing the mounting frame 6, the distance between the center of the infrared sensor 5 and the first plane can be conveniently made greater than the distance between the axis N of the through hole 112 and the first plane, so that the installation of the infrared sensor 5 is convenient.

[0041] In some embodiments, see Figure 8 The touch device 100 further includes a plurality of foot pads 7, which are all disposed on the side of the rear housing 11 away from the screen 2, and are spaced apart from each other. The plurality of foot pads 7 are used to carry the touch device 100. In other words, please refer to Figure 4 When the touch device 100 is placed flat on the desktop H, the plurality of foot pads 7 are all in contact with the desktop H, thereby improving the flatness of the touch device 100 when placed flat on the desktop H.

[0042] In some embodiments, see 4, the touch device 100 further includes a heat dissipation component 8, which is received in the accommodating cavity 111, and is connected to the circuit board 3, so that the heat in the circuit board 3 can be transferred to the heat dissipation component 8 and dissipated through the heat dissipation component 8. In this embodiment, the heat dissipation component 8 is provided to dissipate the heat in the circuit board 3, which is beneficial to improving the heat dissipation efficiency of the circuit board 3 and reducing the risk of the circuit board 3 being overheated and affecting the normal operation of the circuit board 3.

[0043] In some embodiments, the heat dissipation assembly 8 includes a heat dissipation bracket 81 and a heat sink 82. The heat dissipation bracket 81 is connected to the circuit board 3, and the heat sink 82 is connected to the heat dissipation bracket 81. The heat in the circuit board 3 can be transferred to the heat sink 82 through the heat dissipation bracket 81, and then dissipated through the heat sink 82.

[0044] In some embodiments, see Figure 5 , Figure 6 and Figure 7, the touch device 100 further includes a support component 9. The support component 9 is located on the side of the rear shell 11 away from the screen 2, and the support component 9 is connected to the end of the rear shell 11 far from the through hole 112. The support component 9 can rotate relative to the rear shell 11 about a first axis F, where the first axis F is parallel to the outer surface 21 of the screen 2. When the support component 9 rotates to Figure 4 the first position shown in Figure 5 , the touch device 100 can be placed flat on the desktop H. When the support component 9 rotates to

[0045] In some embodiments, please refer to Figure 6 and Figure 7 , the support component 9 includes a support frame 91 and a first rotating hinge 92. The first rotating hinge 92 is fixed to the end of the rear shell 11 far from the through hole 112. The support frame 91 is used to support the touch device 100. One end of the support frame 91 is connected to the first rotating hinge 92, and the first axis F passes through the first rotating hinge 92, so that the support frame 91 can rotate relative to the rear shell 11 about the first axis F, and thus the touch device 100 can be placed obliquely, facilitating the user to observe the screen 2 of the touch device 100.

[0046] In some embodiments, please refer to Figure 7 , the first rotating hinge 92 includes a first fixing member 921 and a first rotating member 922. The first fixing member 921 is fixed to the rear shell 11. The first fixing member 921 is provided with a first rotating hole 9211, and the axis of the first rotating hole 9211 coincides with the first axis F. A part of the first rotating member 922 is inserted into the first rotating hole 9211, and the first rotating member 922 can rotate relative to the first rotating hole 9211. One end of the support frame 91 is connected to the first rotating member 922, so that the support frame 91 can rotate relative to the first rotating hole 9211 about the first axis F, and further enables the support frame 91 to provide support for the touch device 100, making the touch device 100 inclined relative to the desktop H.

[0047] In some embodiments, please refer to Figure 6 and Figure 7, the first rotating hinge 92 further includes a second rotating member 923. A part of the second rotating member 923 is inserted into the first rotating hole 9211, and the second rotating member 923 can rotate relative to the first rotating hole 9211. The second rotating member 923 and the first rotating member 922 are respectively located at both ends of the first rotating hole 9211. The part of the second rotating member 923 protruding from the first rotating hole 9211 is connected to the support frame 91. In this embodiment, by providing the second rotating member 923, the second rotating member 923 can rotate relative to the first rotating hole 9211, which can improve the stability during the rotation of the support frame 91. In addition, there is friction between both the first rotating member 922 and the second rotating member 923 and the inner wall of the first rotating hole 9211. Therefore, by providing the second rotating member 923, the friction can be increased, thereby improving the stability of the support of the support frame 91 for the touch device 100.

[0048] In some embodiments, the support assembly 9 further includes a second rotating hinge 93. The second rotating hinge 93 is fixed to the side of the rear shell 11 facing away from the screen 2, and along the third direction Z, the second rotating hinge 93 and the first rotating hinge 92 are opposite to each other, where the third direction Z is perpendicular to the second direction Y and the first direction X respectively. One end of the support frame 91 away from the first rotating hinge 92 is connected to the second rotating hinge 93, so that both ends of the support frame 91 can rotate relative to the rear shell 11 around the first axis F respectively. In this embodiment, by providing the second rotating hinge 93 and connecting the support frame 91 to the second rotating hinge 93, the stability of the rotation of the support frame 91 can be improved, and since both ends of the support frame 91 are respectively connected to the first rotating hinge 92 and the second rotating hinge 93, the stability of the support of the support frame 91 for the touch device 100 can be improved.

[0049] In some embodiments, the second rotating hinge 93 includes a second fixing member 931, a third rotating member 932, and a fourth rotating member 933. The second fixing member 931 is fixed to the side of the rear shell 11 facing away from the screen 2. The second fixing member 931 is provided with a second rotating hole 9311, and the axis of the second rotating hole 9311 coincides with the first axis F. A part of the third rotating member 932 is inserted into the second rotating hole 9311, and a part of the fourth rotating member 933 is inserted into the second rotating hole 9311. Moreover, the third rotating member 932 and the fourth rotating member 933 are respectively located at both ends of the second rotating hole 9311, and both the third rotating member 932 and the fourth rotating member 933 can rotate relative to the second rotating hole 9311. One end of the support frame 91 away from the first rotating hinge 92 is connected to the part of the third rotating member 932 protruding from the second rotating hole 9311 and the part of the fourth rotating member 933 protruding from the second rotating hole 9311, so that the support frame 91 can rotate relative to the rear shell 11. In this embodiment, by inserting a part of the third rotating member 932 into the second rotating hole 9311 and inserting a part of the fourth rotating member 933 into the second rotating hole 9311, while enabling the support frame 91 to rotate relative to the rear shell 11 around the first axis F, the friction during the rotation of the support frame 91 can be increased, which is beneficial to improving the stability of the support of the support frame 91 for the touch device 100.

[0050] In some embodiments, the support frame 91 includes a first support section 911, a second support section 912, and a connecting section 913. One end of the first support section 911 is connected to one end of the connecting section 913, and the other end of the first support section 911 is connected to the part of the first rotating member 922 and the second rotating member 923 protruding from the first rotating hole 9211. One end of the second support section 912 is connected to the other end of the connecting section 913, and the end of the second support section 912 away from the connecting section 913 is connected to the part of the third rotating member 932 and the part of the fourth rotating member 933 protruding from the second rotating hole 9311.

[0051] In some embodiments, please refer to Figure 8 , the rear shell 11 is provided with a receiving groove 113, and the receiving groove 113 is located on the side of the rear shell 11 facing away from the screen 2. When the support frame 91 rotates to the position where it is received in the receiving groove 113, the touch device 100 can be placed flat on the desktop H. In this embodiment, by providing the receiving groove 113 and receiving the support frame 91 through the receiving groove 113, when the touch device 100 is placed flat on the desktop H, the risk that the support frame 91 interferes with the touch device 100 and causes the touch device 100 to be unstable is reduced.

[0052] In some embodiments, please refer to Figure 5 and Figure 6, the support component 9 further includes a bearing pad 94. The bearing pad 94 is strip-shaped and is attached to the connecting section 913 along the length direction of the connecting section 913. The bearing pad 94 has an arc surface. When the support frame 91 supports the touch device 100 and the touch device 100 is placed obliquely, the arc surface abuts against the desktop H. In this embodiment, by providing an arc surface on the bearing pad 94, when the support frame 91 supports the touch device 100, a line contact can be maintained between the arc surface and the desktop H, increasing the contact area between the bearing pad 94 and the desktop H, which is beneficial to improving the stability of the support of the support frame 91 for the touch device 100.

[0053] In the embodiment of the present invention, by providing a receiving cavity 111 and a through hole 112 in the rear shell 11, the through hole 112 communicates with the receiving cavity 111. The lens 4 covers the through hole 112, and the infrared sensor 5 is received in the receiving cavity 111. And along the first direction X, at least part of the projection of the infrared sensor 5 is located in the through hole 112, so that the infrared sensor 5 can pass through the through hole 112 to sense whether there is a human body in front of the through hole 112. In the second direction Y, there is a height difference between the center of the infrared sensor 5 and the axis N of the through hole 112 relative to the first plane. The first plane coincides with the outer surface 21 of the screen 2, and the axis N of the through hole 112 is parallel to the first plane, so that the sensing direction of the infrared sensor 5 is offset toward the plane where the outer surface of the screen 2 is located. Thus, when the touch device 100 is placed obliquely on the desktop H, the blocking of the desktop H on the infrared sensor 5 can be reduced, which is beneficial to improving the accuracy of the infrared sensor 5 in sensing a human body.

[0054] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
