Description

Technical Field

[0001] This application belongs to the field of communication device technology, specifically relating to a remote control and a video conferencing terminal. Background Technology

[0002] With the development of science and technology, the use of various video conferencing terminals, such as televisions and video conferencing terminals, is becoming increasingly widespread. These terminals require remote controls, which have multiple buttons to control the electronic devices and achieve corresponding functions. However, in some technologies, these buttons are arranged in multiple rows and columns with relatively large spacing, resulting in a bulky remote control. This forces users to frequently change their grip, negatively impacting the user experience. Summary of the Invention

[0003] The purpose of this application is to provide a remote control and video conferencing terminal that can solve the problem in related technologies where the remote control is large in size, causing users to frequently change their holding posture during use, which affects the user experience.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a remote control, including a housing and a button assembly. The button assembly includes a first button and a second button, both of which are located in the housing. Pressing the first button or the second button can trigger a corresponding button function. There are multiple first buttons, which are distributed along an arc and form an installation space. The second button is located within the installation space.

[0006] This application embodiment also provides a video conferencing terminal, including a terminal body and the aforementioned remote controller. The terminal body has a recessed portion, and the remote controller can be disposed within the recessed portion.

[0007] In this embodiment, compared to the technical solution where multiple first buttons are arranged in multiple rows and columns with large gaps between them, the multiple first buttons are distributed along an arc, which reduces the space occupied by the buttons. The multiple first buttons enclose an installation space, and the second button is located within this space, further reducing the overall space occupied by the button assembly. The area of ​​the housing can be adapted to the area of ​​the button assembly, thereby reducing the overall size of the remote control. This makes it easier for users to hold the remote control, eliminating the need for frequent changes in grip posture. Furthermore, reducing the size of the remote control also reduces material costs. Therefore, this application solves the problem in related technologies where the remote control is too large, causing users to frequently change their grip posture and affecting the user experience.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0034] like Figures 1 to 17 As shown, this application discloses a remote control, which includes a housing 100 and a button assembly 200. The button assembly 200 includes a first button 210 and a second button 220. Both the first button 210 and the second button 220 are located in the housing 100. Pressing the first button 210 or the second button 220 can trigger the corresponding button function. There are multiple first buttons 210, which are distributed along an arc and form an installation space. The second button 220 is located within the installation space.

[0035] In one optional embodiment, the adjacent edges of two adjacent first buttons 210 can be fitted together, and the adjacent edges of the second button 220 and each of the first buttons 210 can also be fitted together, so as to reduce the space occupied by the whole formed by the first buttons 210 and the second buttons 220.

[0036] In another optional embodiment, a first gap may be provided between two adjacent first buttons 210. This first gap prevents friction between the pressed first button 210 and its adjacent first button 210 when one of the first buttons 210 is pressed. A second gap may be provided between the second button 220 and the entire assembly formed by the first buttons 210. This second gap prevents friction between the first button 210 and the second button 220 when either the first button 210 or the second button 220 is pressed. This structure reduces the space occupied by the entire assembly of the first buttons 210 and the second button 220, prevents friction damage to the first buttons 210 and the second button 220, and avoids problems with smooth button pressing due to friction.

[0037] The number of first buttons 210 can be 9. Please refer to this again. Figure 1 In a clockwise direction, the plurality of first buttons 210 may sequentially include a first button 210 for controlling sound on or off, a first button 210 for controlling volume up, a first button 210 for controlling volume down, a first button 210 for controlling page turning right, a first button 210 for controlling screen freeze, a first button 210 for controlling page turning left, a first button 210 for controlling page shrinking, a first button 210 for controlling page zooming, and a first button 210 for controlling video on or off. It should be noted that the arrangement order of the first buttons 210 can be rearranged; this application does not limit the arrangement order of the first buttons 210, nor does it limit the number of first buttons 210.

[0038] The first button 210 can be a fan-shaped ring structure, and multiple first buttons 210 can be distributed along an arc. The second button 220 can be a circular structure. The center line a of the first button 210 passes through the center of the arc where the first button 210 is located. The included angle between the center lines a of two adjacent first buttons 210 can be 33°. Of course, when the first buttons 210 form a ring structure with an opening, the included angle between the center lines a of two first buttons 210 located at both ends of the opening can be different from 33°.

[0039] Of course, the multiple first buttons 210 can also be distributed along an elliptical arc. The cross-section of the housing 100 can be circular or elliptical, and the cross-section of the housing 100 refers to the cross-section parallel to the plane where the button assembly 200 is located. The material of the first button 210 and the second button 220 can both be PC (polycarbonate) + 10% GF (glass fiber), and the material of the housing 100 can be PC + ABS (acrylonitrile butadiene styrene copolymer). Of course, the housing 100, the first button 210, and the second button 220 can also be made of other materials, and this application does not limit this.

[0040] In this embodiment, the multiple first buttons 210 are distributed along an arc shape. Compared to a multi-row, multi-column arrangement of the first buttons 210, this reduces the space occupied by the multiple first buttons 210. The multiple first buttons 210 surround the installation space, and the second button 220 is located within the installation space, further reducing the overall space occupied by the button assembly 200. The area of ​​the housing 100 can be adapted to the area of ​​the button assembly 200, thereby reducing the overall size of the remote control. This makes it easier for users to hold the remote control, eliminating the need for frequent changes in grip posture. Furthermore, reducing the size of the remote control also reduces the material cost. Therefore, this application solves the problem in related technologies where the remote control is too large, causing users to frequently change their grip posture during use, thus affecting the user experience.

[0041] The second button 220 can correspond to one button function, or the second button 220 can include multiple pressing parts 221, and pressing each pressing part 221 can trigger the corresponding button function. In this way, the second button 220 corresponds to multiple button functions. Please refer again. Figure 4 The number of pressing parts 221 can be four, and the four pressing parts 221 can be evenly distributed along the circumference of the second button 220. Of course, the shape of the second button 220 and the number of pressing parts 221 can be adjusted according to needs, and this application does not limit this. In this case, the second button 220 corresponds to multiple button functions. When the number of button functions of the remote control is fixed, the space occupied by the arc formed by the first button 210 can be reduced, thereby further reducing the space occupied by the button assembly 200.

[0042] During the pressing of the first button 210 or the second button 220, the first button 210 or the second button 220 moves relative to the housing 100. After the force of pressing the first button 210 or the second button 220 disappears, the first button 210 or the second button 220 returns to its initial position.

[0043] Therefore, in one optional embodiment, both the first button 210 and the second button 220 can be provided with elastic structural components such as springs or elastic columns. One end of the elastic structural component is connected to the first button 210 or the pressing part 221, and the other end of the elastic structural component is connected to the housing 100. When the first button 210 or the pressing part 221 is pressed, the first button 210 or the pressing part 221 moves relative to the housing 100, and the corresponding elastic structural component deforms and accumulates the potential energy to recover the deformation. After the force of pressing the first button 210 or the pressing part 221 disappears, the elastic structural component recovers its deformation to drive the first button 210 or the pressing part 221 back to its initial position.

[0044] In another optional embodiment, both the first button 210 and the second button 220 may be provided with a first hook 240, and the housing 100 may be provided with a plurality of second hooks 114. The first hooks 240 can be engaged with the corresponding second hooks 114. Both the first button 210 and the second button 220 may be provided with a first elastic element 250. The other end of the first elastic element 250 can act on the housing 100. When the first button 210 or the pressing part 221 is pressed, the corresponding first elastic element 250 undergoes elastic deformation, and the corresponding first hooks 240 and second hooks 114 separate from each other. When the first button 210 or the pressing part 221 is not pressed, the corresponding first elastic element 250 drives the corresponding first hook 240 to engage with the second hook 114. When the first hooks 240 and the second hooks 114 are engaged, the corresponding first button 210 or the pressing part 221 and the housing 100 are limited in a direction away from each other.

[0045] In this case, the deformation and recovery process of the first elastic element 250 can provide a stable travel for the first button 210 or the pressing part 221, and the connection between the button assembly 200 and the housing 100 can be realized through the cooperation of the first hook 240 and the second hook 114, and the connection stability is good, which can prevent the button assembly 200 from detaching from the housing 100.

[0046] The first elastic element 250 can be an elastic column or spring, etc., and the first elastic element 250 can be directly provided on each first button 210 or pressing part 221.

[0047] Pressing the first button 210 or the pressing part 221 can trigger the corresponding button function. Therefore, in this embodiment, the remote control may further include a circuit board assembly 300. The housing 100 may have a receiving cavity, and the circuit board assembly 300 may be disposed in the receiving cavity. The surface of the circuit board assembly 300 facing the button assembly 200 may have multiple dome switches 330. Both the first button 210 and the pressing part 221 may be provided with a second elastic member 260. The housing 100 is provided with multiple first connecting holes 113 communicating with the receiving cavity. Each second elastic member 260 passes through the corresponding first connecting hole 113 and faces the corresponding dome switch 330. When the first button 210 or the pressing part 221 is pressed, the corresponding second elastic member 260 presses against the corresponding dome switch 330 to trigger the corresponding button function.

[0048] In this case, compared with the technical solution where the second elastic element 260 is a rigid structural component, the second elastic element 260 is elastic, which enables the contact between the second elastic element 260 and the hot plate 330 to be elastic contact, thereby playing a role in protecting the hot plate 330.

[0049] The first button 210 may have two first hooks 240 and one second elastic element 260, and the two first hooks 240 and the second elastic element 260 may be located on the center line a of the first button 210, and the center line a of the first button 210 passes through the center of the arc of the circle in which the first button 210 is located. The second button 220 may have two first hooks 240 and four second elastic elements 260, and the four second elastic elements 260 may be distributed at 90° intervals and correspond to the four pressing parts 221 respectively. In order to facilitate pressing, the second elastic elements 260 on the second button 220 may be close to the edge of the second button 220.

[0050] The circuit board assembly 300 can be composed of a first circuit board 310 and a second circuit board 320. The first circuit board 310 is adjacent to the button assembly 200. The first circuit board 310 has a dome switch 330 conduction circuit and multiple dome switches 330 are distributed on the first circuit board 310. The second circuit board 320 has a chip and a power conduction circuit. The second circuit board 320 has a main chip, a battery contact socket 340 and other circuit components. The battery contact socket 340 can be soldered to the second circuit board 320 through two pins. The first circuit board 310 and the second circuit board 320 are connected through each node.

[0051] When the first button 210 or the pressing part 221 is pressed, the first elastic element 250 deforms to provide a stable travel distance for the first button 210 or the pressing part 221. The second elastic element 260 follows the first elastic element 250 and moves towards the dome switch 330. The second elastic element 260 continues to move and press the dome switch 330. When the pressing force of the second elastic element 260 on the dome switch 330 exceeds the working starting force of the dome switch 330, the dome switch 330 deforms under force, and the dome switch contact 331 contacts the second exposed copper 312, forming a conductive circuit. Thus, the electrical signal will flow from the first exposed copper 311, along the dome switch 330, from the dome switch contact 331 to the second exposed copper 312, thereby forming an effective electrical signal. The electrical signal is then transmitted to the chip in the second circuit board 320. The chip recognizes the electrical signal, processes the electrical signal, and responds accordingly to realize the corresponding button function.

[0052] Please refer to this again. Figure 13 The dome switch 330 can be an arc-shaped metal spring. Under pressure, the dome switch contact 331 deforms and comes into contact with the second exposed copper 312 in the first circuit board 310, thereby connecting the first exposed copper 311 and the second exposed copper 312, so that the dome switch 330 conduction circuit of the circuit board assembly 300 is turned on and an electrical signal is generated.

[0053] The starting force of the dome switch 330 can be 130gf, and the working height (the displacement of the dome switch 330 in the direction perpendicular to the first circuit board 310 after being pressed) can be 0.27mm. The pressing force of the first button 210 or the pressing part 221 needs to overcome the counter-thrust force generated by the deformation of the first elastic element 250 and the second elastic element 260. The pressing force range of the first button 210 or the pressing part 221 is 150gf-180gf.

[0054] The number of dome switches 330 can be equal to the total number of first buttons 210 and pressing parts 221, and they correspond one-to-one. For example, if there are 9 first buttons 210 and 4 pressing parts 221, the number of dome switches 330 can be 13.

[0055] To provide a signal that the first button 210 or the pressing part 221 has been effectively pressed, the first circuit board 310 may also have an indicator light. When the dome switch 330 of the first circuit board 310 operates to generate an electrical signal, the chip processes the electrical signal and controls the indicator light to flash, indicating that the button has been effectively pressed. A third connecting hole 117 opposite to the indicator light may be provided on the housing 100. The first button 210 and the second button 220 avoid the third connecting hole 117 so that the light emitted by the indicator light can leak out of the housing 100.

[0056] Furthermore, a light guide post can be provided between the indicator light and the third connecting hole 117 to conduct the light emitted by the indicator light to the outside of the housing 100. Part of the light guide post can extend into the third connecting hole 117 and be connected to the hole wall of the third connecting hole 117 by heat fusion. The outer wall of the light guide post can be sealed and fitted to the hole wall of the third connecting hole 117 to prevent external debris from entering the housing 100 through the third connecting hole 117 or falling onto the circuit board assembly 300, causing problems such as short circuit of the circuit board assembly 300.

[0057] In one optional embodiment, the second elastic element 260 may be made of silicone. In another optional embodiment, the second elastic element 260 may also include a guide post and a silicone layer sleeved outside the guide post. The guide post may be made of plastic, or other materials with higher hardness. In this case, while ensuring the elasticity of the second elastic element 260, it also avoids the problem of the second elastic element 260 being too flexible and bending excessively, thereby failing to effectively press the corresponding dome switch 330.

[0058] To improve the tactile feel of the first button 210, the second elastic element 260 located on the first button 210 can be positioned at the center of mass of the first button 210 to enhance the user experience. The first button 210 can be a fan-shaped structure, and its material can be PC+10%GF. The center of mass of the first button 210 is located on the centerline a of the first button 210, and is offset by 14% from the center of the first button 210 away from the second button 220. The 14% refers to the length of the first button 210 in the direction of the centerline a.

[0059] Each first button 210 can be an independent component. When each first button 210 is an independent component, in order to integrate each first button 210 and the second button 220, the button assembly 200 can also include a button integration component 230. The button integration component 230 can be an elastic structural component. The button integration component 230 is provided with multiple second connecting holes 231. Each second elastic element 260 passes through the corresponding second connecting hole 231 and the first connecting hole 113 in sequence and is opposite to the corresponding dome switch 330. The second elastic element 260 can be fixedly connected to the hole wall of the second connecting hole 231 by dispensing glue.

[0060] In this case, the button assembly 230 is elastic and deformable, which can compensate for a certain dimensional error of the second elastic element 260. For example, when the size of the second elastic element 260 is too small, pressing the button assembly 230 towards the dome switch 330 will deform the button assembly 230 so that the second elastic element 260 can press against the dome switch 330. When the size of the second elastic element 260 is too large, the second elastic element 260 and the dome switch 330 will cause the second elastic element 260 to deform. Under the action of the counter-thrust force generated by the deformation of the second elastic element 260, the second elastic element 260 and the dome switch 330 can be prevented from being locked together.

[0061] The button assembly 230 can be made of silicone with a hardness of 70 (Shore hardness). All silicone components mentioned above use silicone with a hardness of 70 (Shore hardness). Of course, the button assembly 230 can also be made of other elastic materials; this application does not impose any restrictions on this.

[0062] The first elastic element 250 can be disposed on the surface of the button assembly 230 facing the housing 100. The first elastic element 250 may include protrusions 251 and second ribs 252. Multiple protrusions 251 are provided in the area of ​​the button assembly 230 corresponding to each first button 210. The protrusions 251 have a height of 0.45 mm, a diameter of 1 mm, and a rounded end radius R0.3. Their height direction is perpendicular to the plane where the button assembly 200 is located. A second rib 252 and multiple protrusions 251 are provided in the area of ​​the button assembly 230 corresponding to the second button 220. The second rib 252 includes a central portion with an arc shape and an extension portion extending from the central portion. The extension portion extends in a direction offset from the second elastic element 260 at 45°, and has a length of 4 mm. The second rib 252 has a width of 1 mm and a height of 0.45 mm. Each protrusion 251 is located on the extension line of its respective extension portion. The first elastic element 250 contacts the housing 100, achieving a working stroke of 0.4 mm.

[0063] In a further technical solution, the shell wall of the housing 100 facing the button assembly 200 may have a first part 111 and a second part 112. The first part 111 is recessed into the second part 112 in a direction close to the circuit board assembly 300 to form a first groove with the slot facing away from the circuit board assembly 300 and a second groove with the slot facing the circuit board assembly 300. The button assembly 200 may be disposed in the first groove, and when the button assembly 200 is not pressed, the surfaces of the button assembly 200 and the second part 112 facing away from the circuit board assembly 300 may be coplanar. The remote control also includes an onboard antenna for transmitting and receiving Bluetooth signals. The onboard antenna is soldered to the circuit board assembly 300. The onboard antenna may be disposed in the second groove, and the shape of the onboard antenna may be adapted to the shape of the second groove.

[0064] In this case, the coplanarity of the surfaces of the button assembly 200 and the second part 112 away from the circuit board assembly 300 is beneficial to the aesthetics of the remote control and can alleviate the problem of accidental pressing of the first button 210 or the second button 220. The shape of the first groove can be adapted to the shape of the button assembly 200, and the shapes of the second part 112 and the second groove can be fan-shaped.

[0065] In other embodiments, when the button assembly 200 is not pressed, the surface of the button assembly 200 facing away from the circuit board assembly 300 may protrude from the second portion 112 in a direction away from the circuit board assembly 300. This structure makes it easier to press each of the first buttons 210 or the pressing portion 221.

[0066] The third connecting hole 117 in the above embodiment can be formed in the second part 112.

[0067] In the above scheme, pressing the first button 210 or the second button 220 can trigger the corresponding button function. The remote control may also include a circuit board assembly 300. The housing 100 may have a receiving cavity, and the circuit board assembly 300 may be disposed in the receiving cavity. The surface of the circuit board assembly 300 facing the button assembly 200 may have multiple dome switches 330. When the first button 210 or the second button 220 is pressed, the first button 210 or the second button 220 presses against the corresponding dome switch 330 to trigger the corresponding button function.

[0068] To power the circuit board assembly 300, the remote control may also include a battery. The circuit board assembly 300 may have a battery contact 340, in which the battery is disposed for powering the circuit board assembly 300. Please refer again. Figure 12 The arrow in the diagram indicates the direction in which the battery is inserted into the battery contact seat 340. The housing 100 may have a mounting hole 121 communicating with the receiving cavity, and the mounting hole 121 is opposite to the battery contact seat 340. In this case, the battery can be replaced without disassembling the housing 100, which facilitates battery inspection and replacement.

[0069] The battery can be inserted into the battery contact 340 of the second circuit board 320 to form a conductive circuit, thereby supplying power to the circuit board assembly 300 and the chips and other components disposed on the circuit board assembly 300.

[0070] The housing 100 includes a first housing 110 and a second housing 120. The first housing 110 and the second housing 120 are connected to form a receiving cavity. The button assembly 200 is disposed in the first housing 110, and the mounting hole 121 is opened in the second housing 120. The remote control also includes a battery cover 400, which is detachably connected to the first housing 110. The second housing 120 is located inside the battery cover 400, and the outer surface of the battery cover 400 smoothly transitions with the outer surface of the first housing 110.

[0071] In the battery cover 400 and the first shell 110, one is provided with a plurality of first ribs 115 spaced apart along its circumference, and the other is provided with a plurality of limiting blocks 410 spaced apart along its circumference. The first ribs 115 are provided with limiting grooves 1151, and the limiting blocks 410 extend into the limiting grooves 1151.

Optionally, the first housing 110 and the second housing 120 may be connected by screws, and the circuit board assembly 300 may also be connected to the second housing 120 by screws or other means.

[0074] In this case, the smooth transition between the outer surface of the battery cover 400 and the outer surface of the first shell 110 helps to improve the aesthetics of the remote control. This structure also allows the second shell 120, the circuit board assembly 300, and the battery to be located in the cavity formed by the battery cover 400 and the first shell 110, which can protect the circuit board assembly 300 and the battery.

[0075] In one alternative embodiment, the battery cover 400 may be provided with a first magnetic element, such as a magnet or an energized coil, and the first housing 110 may be provided with a second magnetic element, such as a magnet or an energized coil. The first magnetic element and the second magnetic element attract each other, so that the battery cover 400 and the first housing 110 are detachably connected.

[0076] In another alternative embodiment, in the battery cover 400 and the first shell 110, one may be provided with a plurality of first ribs 115 spaced apart along its circumference, and the other may be provided with a plurality of limiting blocks 410 spaced apart along its circumference. The first ribs 115 may be provided with limiting grooves 1151, and the limiting blocks 410 may extend into the limiting grooves 1151. The limiting blocks 410 and the limiting grooves 1151 are mutually limiting and cooperating in the direction in which the first shell 110 and the battery cover 400 are far apart.

[0077] Optionally, the first rib 115 can be provided on the surface of the first shell 110 facing the battery cover 400, and there can be a first distance between the first rib 115 and the edge of the first shell 110 to form a step 118 at the edge of the first shell 110. The limiting block 410 can be provided on the inner wall of the battery cover 400, and the battery cover 400 can be mounted on the step 118. The limiting block 410 extends into the limiting groove 1151. The limiting block 410 can be provided with a chamfer, which can be provided at the end of the limiting block 410 facing the bottom of the limiting groove 1151. Of course, the end of the limiting block 410 away from the bottom of the limiting groove 1151 can also be provided with a chamfer. The fitting clearance between the limiting block 410 and the groove wall of the limiting groove 1151 can be 0.1mm.

[0078] In the battery cover 400 and the first shell 110, one is provided with a first snap-fit ​​protrusion 116 and the other is provided with a second snap-fit ​​protrusion 420.

[0079] The engagement of the first latching protrusion 116 and the second latching protrusion 420 prevents the battery cover 400 and the first shell 110 from rotating relative to each other. When it is necessary to separate the battery cover 400 and the first shell 110, an external force can be applied to the battery cover 400 and the first shell 110 to rotate relative to each other, causing the first latching protrusion 116 and the second latching protrusion 420 to separate from each other. Continue to rotate relative to each other to move the limiting block 410 between the two first ribs 115, so that the first shell 110 and the battery cover 400 move away from each other, thus separating the first shell 110 and the battery cover 400 and completing the separation of the battery cover 400 and the first shell 110.

[0080] In this case, the detachable connection is achieved by screwing and snapping, which is simple in structure and facilitates the assembly and disassembly of the battery cover 400 and the first shell 110. The circuit board assembly 300 is not affected by the magnetic field of the magnetic component.
