Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a bracket structure and communication terminal equipment. Background Art

[0002] Living in an open environment requires a large outdoor CPE (Customer Premise Equipment) to receive base station signals to solve the problem of low base station coverage and poor signal.

[0003] The traditional CPE installation method is to let the installer find the angle with the strongest signal, and then fix the CPE outdoors at the adjusted angle. However, this installation method has many disadvantages. The biggest problem is that after the CPE angle is fixed, it is difficult to adjust the product angle without professional treatment. Due to the influence of factors such as the surrounding environment and climate, the directionality of the base station signal will change. Therefore, it is difficult to ensure that the CPE always receives the base station signal well.

[0004] In the related art, although the angle of CPE can be adjusted through a bracket, the stability of the bracket itself is poor. When in severe weather such as strong winds, rain and snow, or when subjected to external forces such as collisions or vibrations, the bracket will move, causing the adjusted CPE angle to deviate, thus affecting the signal reception effect. Summary of the invention

[0005] The embodiments of the present invention aim to at least solve the problem in the prior art that the bracket has poor stability, which easily leads to deviation in the angle of the adjusted CPE and affects the signal reception effect, and propose a bracket structure and a communication terminal device.

[0006] In the first aspect, an embodiment of the present invention discloses a bracket structure, comprising: a first bracket, used to be fixedly connected to a support; a second bracket, used to install a body of a communication terminal device, the second bracket being movably connected to the first bracket, the second bracket having a first position and a second position relative to the first bracket; in the first position of the second bracket, the second bracket is rotatable relative to the first bracket; in the second position of the second bracket, the second bracket is limitedly cooperated with the first bracket in the rotation direction; a first driving device, drivingly cooperated with the second bracket located at the first position, so as to drive the second bracket to rotate.

[0007] In a second aspect, an embodiment of the present invention further discloses a communication terminal device, comprising: a main body; and the above-mentioned bracket structure, wherein the main body is fixedly connected to the bracket structure.

[0008] The bracket structure of the embodiment of the present invention is provided with a first bracket and a second bracket and the first bracket is movably connected with the second bracket, so that the second bracket has a first position and a second position relative to the first bracket, and switches between the first position and the second position by moving. That is to say, the second bracket can not only rotate relative to the first bracket by moving, but also cooperate with the first bracket in a limited position, so that the second bracket and the first bracket exist in two matching states, and then cooperate with the first driving device to rotate. Therefore, after the communication terminal equipment is installed outdoors through the bracket structure of the embodiment of the present invention, when the angle of the communication terminal equipment needs to be adjusted, the second bracket can be moved to the first position, so that the first driving device drives the second bracket to rotate, so as to adjust the signal receiving angle, and after the adjustment is completed, the second bracket is moved to the second position, so that the second bracket forms a limited position with the first bracket, so as to prevent the second bracket from being affected by bad weather such as strong wind, rain and snow, or by external forces such as collision or vibration, resulting in the deviation of the signal receiving angle, thereby improving the stability and reliability of signal reception.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the support structure and communication terminal equipment provided by the present invention are described in detail below with reference to the accompanying drawings.

[0019] Example embodiments will be described more fully below with reference to the accompanying drawings, but example embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, the purpose of providing these embodiments is to make this disclosure thorough and complete and to enable those skilled in the art to fully understand the scope of this disclosure.

[0020] like Figure 1 An embodiment of the present invention shown in the figure discloses a bracket structure, including: a first bracket 10, a second bracket 20 and a first driving device 30. The first bracket 10 is used to be fixedly connected to a support; the second bracket 20 is used to install a communication terminal device, the second bracket 20 is movably connected to the first bracket 10, and the second bracket 20 has a first position and a second position relative to the first bracket 10; in the first position of the second bracket 20, the second bracket 20 is rotatable relative to the first bracket 10, and at the same time, the first driving device 30 drives and cooperates with the second bracket 20 located at the first position, so that the first driving device 30 drives the second bracket 20 to rotate; in the second position of the second bracket 20, the second bracket 20 is limitedly matched with the first bracket 10 in the rotation direction.

[0021] The bracket structure of the embodiment of the present invention is provided with a first bracket 10 and a second bracket 20, and the first bracket 10 and the second bracket are movably connected, so that the second bracket 20 has a first position and a second position relative to the first bracket 10, and switches between the first position and the second position by moving. That is to say, the second bracket 20 can rotate relative to the first bracket 10 and can be limitedly matched with the first bracket 10 by moving, so that the second bracket 20 and the first bracket 10 exist in two matching states, and then cooperate with the first driving device 30. Therefore, after the communication terminal equipment is installed outdoors through the bracket structure of the present invention, when the angle of the communication terminal equipment needs to be adjusted, the second bracket 20 can be moved to the first position, so that the first driving device 30 drives the second bracket 20 to rotate, thereby realizing the adjustment of the signal receiving angle, and after the adjustment is completed, the second bracket 20 is moved to the second position, so that the second bracket 20 forms a limited match with the first bracket 10, thereby preventing the second bracket 20 from being affected by severe weather such as strong wind, rain and snow or by external forces such as collision or vibration, resulting in the deviation of the signal receiving angle, thereby improving the stability and reliability of signal reception.

[0022] like Figure 2 As shown, in some embodiments, the first bracket 10 includes a fixing seat 12 and a connecting plate 14. The fixing seat 12 is fixedly connected to the connecting plate 14, and the fixing seat 12 is fixedly installed at a position required to be installed outdoors through the connecting plate 14. The fixing seat 12 is provided with a mounting hole 121.

[0023] like Figure 3 As shown, in some embodiments, the second bracket 20 includes: a rotating seat 21, a driving shaft 22 and a driving gear 24. The rotating seat 21 is provided with a mounting groove 211 for mounting the communication terminal device; the first end of the driving shaft 22 is fixedly connected to the rotating seat 21, and the second end of the driving shaft 22 is provided with a driving gear 24. The driving shaft 22 is driven and matched with the first driving device 30 through the driving gear 24. The driving shaft 22 is inserted into the mounting hole 121 of the first bracket 10, that is, the driving shaft 22 is accommodated in the mounting hole 121, and the driving shaft 22 can move relative to the mounting hole 121 along its own axis. At the same time, the driving shaft 22 can also rotate in the mounting hole 121, so that the rotating seat 21 is movably connected to the first bracket 10 through the driving shaft 22; in addition, since the driving shaft 22 is accommodated in the mounting hole 121, during the axial movement of the rotating seat 21, the driving shaft 22 can also cooperate with the mounting hole 121 to play a guiding role.

[0024] When in use, in the first position of the second bracket 20, the rotating seat 21 and the first bracket 10 are away from each other, and the driving shaft 22 is driven and cooperated with the first driving device 30 through the driving gear 24, so that the driving shaft 22 drives the rotating seat 21 to rotate; in the second position of the second bracket 20, the rotating seat 21 and the first bracket 10 are close to each other, the driving gear 24 of the driving shaft 22 is disengaged from the first driving device 30, and at the same time, the rotating seat 21 is limitedly cooperated with the first bracket 10.

[0025] In such Figures 2 to 5 In some of the embodiments shown, the support structure further includes: a second driving device 40 , which is respectively connected to the first support 10 and the rotating seat 21 , and is used to drive the rotating seat 21 away from or close to the first support 10 .

[0026] Specifically, if Figure 4 As shown, the second driving device 40 includes: a first magnet 41 and a second magnet 42 , the first magnet 41 is arranged on the first bracket 10 ; the second magnet 42 is arranged on the rotating seat 21 , and the position of the first magnet 41 corresponds to the position of the second magnet 42 .

[0027] See also Figure 3 The second magnet 42 protrudes from the surface of the rotating seat 21 along the axial direction of the driving shaft 22 to form a second limiting portion 23. There are multiple second magnets 42, and the multiple second magnets 42 are distributed at intervals around the driving shaft 22. Figure 2 The first bracket 10 is provided with a limiting groove corresponding to the second magnet 42 to form a first limiting portion 11, and the first magnet 41 is located in the limiting groove.

[0028] The second driving device 40 has a repulsive state and an attractive state. Figure 4 In the repulsive state shown, under the action of the repulsive force between the first magnet 41 and the second magnet 42, the rotating seat 21 and the first bracket 10 move away from each other, that is, the second bracket 20 moves to the first position, and the second magnet 42 disengages from the limiting groove (that is, the second limiting portion 23 disengages from the first limiting portion 11), so that the first bracket 10 and the second bracket 20 are disengaged from the limiting cooperation; Figure 5 In the attractive state shown, under the action of the attraction between the first magnet 41 and the second magnet 42, the rotating seat 21 and the first bracket 10 approach each other, that is, the second bracket 20 moves to the second position, and the second magnet 42 is located in the limiting groove and forms a limiting fit (that is, the second limiting portion 23 and the first limiting portion 11 form a limiting fit), so that the first bracket 10 and the second bracket 20 are limited in the direction of rotation around the driving shaft 22.

[0029] It can be understood that the first magnet 41 and the second magnet 42 are electromagnets, and the second driving device 40 can be in an attractive state and a repulsive state by controlling the direction of the current. Specifically, the electromagnet includes an iron core and an electromagnetic coil wound on the iron core. By controlling the direction of the current on the electromagnetic coil, the magnetic poles generated at both ends of the iron core can be reversed. When in use, the first magnet 41 and the second magnet 42 are arranged relative to each other, so that the first end of the iron core of the first magnet 41 is opposite to the first end of the iron core of the second magnet 42. In the attractive state, the magnetic poles generated by the first end of the iron core of the first magnet 41 and the first end of the iron core of the second magnet 42 are opposite, so that the first magnet 41 and the second magnet 42 attract each other; in the repulsive state, the magnetic poles generated by the first end of the iron core of the first magnet 41 and the first end of the iron core of the second magnet 42 are the same, so that the first magnet 41 and the second magnet 42 repel each other.

[0030] It should be noted that in the above embodiment, although the first magnet 41 and the second magnet 42 are electromagnets, this is not restrictive. In some other embodiments not shown in the figure, one of the first magnet 41 or the second magnet 42 can be a permanent magnet. As long as the device can realize the mutual cooperation or attraction between the first magnet 41 and the second magnet 42 through electromagnetism, it is within the protection scope of the present invention.

[0031] The bracket structure of the embodiment of the present invention can realize the movement of the first bracket 10 and the second bracket 20 between the first position and the second position by setting the first magnet 41 and the second magnet 42, and can realize remote adjustment by cooperating with the communication terminal device. In addition, in the above embodiment, the second magnet 42 forms the second limit portion 23, and the first magnet 41 is arranged inside the first limit portion 11, that is, the second magnet 42 can cooperate with the first limit portion 11, and the second magnet 42 can cooperate with the first magnet 41 to drive the first bracket 10 and the second bracket 20 to move, and the second magnet 42 can also play the role of cooperating with the first limit portion 11, which is a typical dual-purpose object, which simplifies the overall structure of the bracket and reduces the manufacturing cost.

[0032] In this embodiment, the second magnet 42 protrudes from the surface of the rotating seat 21 along the axial direction of the driving shaft 22 to form a second limiting portion 23, and the first magnet 41 is located in the limiting groove. However, this is not restrictive. In some other embodiments not shown in the figure, the first magnet 41 protrudes from the surface of the first bracket 10 along the axial direction of the driving shaft 22, and a limiting groove can be provided on the rotating seat 21, and the second magnet 42 is arranged in the limiting groove. In other words, it is feasible to limit the first magnet 41 and the limiting groove on the rotating seat 21. The above embodiments are all within the protection scope of the present invention without violating the inventive concept of the present invention.

[0033] like Figure 4 As shown, in some embodiments, the first bracket 10 further includes: a protective cover 13, the fixed seat 12 has a first side and a second side, the mounting hole 121 extends from the first side of the fixed seat 12 to the second side, the drive shaft 22 extends from the first side of the fixed seat 12 to the second side, the rotating seat 21 is located on the first side of the fixed seat 12, and the first drive device 30 is arranged on the second side of the fixed seat 12; the protective cover 13 is arranged on the second side of the fixed seat 12, the protective cover 13 and the fixed seat 12 form a protective space, and the drive shaft 22 and the first drive device 30 located on the second side of the fixed seat 12 are located in the protective space. In this embodiment, the first drive device 30 is a drive motor, the drive motor is fixedly connected to the second side of the fixed seat 12, and a transmission gear is arranged on the output shaft of the drive motor.

[0034] like Figure 4 As shown, in the first position of the second bracket 20, the transmission gear 31 on the driving motor is meshed with the driving gear 24 on the driving shaft 22, so that the driving motor can drive the driving shaft 22 to rotate, thereby rotating the rotating seat 21. Figure 5 As shown, in the second position of the second bracket 20 , the transmission gear 31 and the driving gear 24 are misaligned so that the two are out of engagement and the driving motor can no longer drive the rotating seat 21 to rotate.

[0035] The support structure of the embodiment of the present invention is provided with a protective cover 13 to cover the first driving device 30 inside the protective cover 13, thereby protecting the first driving device 30 and preventing the support from being affected by rain, dust, etc. when used outdoors, thereby improving the reliability of the support structure.

[0036] It should be noted that, in the first embodiment, although the second driving device 40 is the first magnet 41 and the second magnet 42, this is not restrictive. In some other embodiments not shown in the figures, the second driving device 40 may also be other devices.

[0037] In some embodiments, the second driving device 40 is a telescopic rod disposed on the first bracket 10, and the relative movement between the first bracket 10 and the second bracket 20 is achieved by the telescopic rod being extended and retracted. Of course, in order to ensure that the first bracket 10 and the second bracket 20 are relatively rotatable, the telescopic rod and the second bracket 20 may be movably connected. In other words, any device that can achieve relative movement between the first bracket 10 and the second bracket 20 is within the protection scope of the present invention.

[0038] like Figure 6 and Figure 7As shown, in some embodiments, the first bracket 10 has a first limiting portion 11, and the rotating seat 21 is provided with a second limiting portion 23, and the first limiting portion 11 matches the second limiting portion 23. In this embodiment, the first limiting portion 11 is a limiting groove, and the second limiting portion 23 is a limiting protrusion. There are multiple limiting grooves, and the multiple limiting grooves are arranged on the fixed seat 12 at intervals along the circumference of the mounting hole 121. There are also multiple limiting protrusions and they are arranged one by one with the limiting grooves, that is, the multiple limiting protrusions are distributed at intervals around the circumference of the driving shaft 22 along the axial direction of the driving shaft 22.

[0039] like Figure 6 As shown, when the telescopic rod is extended, the second bracket 20 moves to the first position, and the limiting groove and the limiting protrusion are separated from each other, so that the rotating seat 21 rotates around the driving shaft 22; Figure 7 As shown, when the telescopic rod contracts, the second bracket 20 moves to the second position, and the limiting protrusion enters the limiting groove, thereby achieving the circumferential limit fit of the driving shaft 22.

[0040] It should also be noted that, in this embodiment, although the first limiting portion 11 is a limiting groove and the second limiting portion 23 is a limiting protrusion, this is not restrictive. In some other embodiments not shown in the figure, the first limiting portion 11 can also be a limiting protrusion and the second limiting portion 23 can be a limiting groove. In other words, as long as the structure can achieve limiting cooperation, it is within the protection scope of the present invention without violating the inventive concept of the present invention.

[0041] The embodiment of the present invention also discloses a communication terminal device, including: a body, an antenna, the above-mentioned bracket structure and a control device, wherein the body is fixedly connected to the bracket structure, the antenna is arranged on the body for receiving signals, and the control device is arranged in the body. The bracket structure has a second driving device 40, which is respectively connected to the first bracket 10 and the second bracket 20, and the second driving device 40 is used to drive the first bracket 10 to move between the first position and the second position; the control device is respectively connected to the antenna, the first driving device 30 and the second driving device 40 for communication, and the control device is used to control the first driving device 30 and the second driving device 40 according to the signal strength of the antenna to adjust the angle at which the antenna receives the signal.

[0042] The communication terminal device of the embodiment of the present invention installs the main body on the bracket structure and fixes the listening terminal device to the pole or wall through the bracket structure. When in use, the communication terminal device can remotely control the angle of the bracket structure using the control device according to the strength of the antenna receiving signal, thereby realizing remote adjustment of the receiving angle of the antenna.

[0043] Take the communication terminal device as a router as an example. The housing of the router is fixedly mounted on the second bracket 20. When the router detects that the signal strength is lower than the preset value, the control device controls the first magnet 41 and the second magnet 42 in the second drive device 40 to be in a mutually repelling state, so that the second bracket 20 moves to the first position. At the same time, the first drive device 30 is started, so that the second bracket 20 located at the first position rotates a certain angle to reach position one. At this time, the router records the signal strength at position one, and then controls the second bracket 20 to continue to rotate by the same angle to position two, and then records the signal strength at position two. This cycle is repeated until the signal strengths of all positions are recorded within the rotation range, and then the signal strengths of each position are compared. Finally, the second bracket 20 is driven to rotate to the position with the strongest signal through the first drive device 30. After the second bracket 20 rotates to the position with the strongest signal, the control device controls the first magnet 41 and the second magnet 42 of the second drive device 40 to be in an attracting state, so that the second bracket 20 moves to the second position again, and the limit fit in the rotation direction is completed.

[0044] It can be understood that in order to ensure that the second bracket 20 and the first bracket 10 can cooperate smoothly when moving from the first position to the second position, the angle of each rotation of the driving motor is the angle between two adjacent first limit parts 11, that is, each time the driving motor drives the second bracket 20 to rotate, the first limit part 11 corresponds to a second limit part 23, thereby ensuring that after adjusting to the position with the strongest signal, the second limit part 23 still corresponds one-to-one with the first limit part 11, so that the second bracket 20 can cooperate smoothly with the first bracket 10 when moving from the first position to the second position, thereby ensuring the reliability of the communication terminal equipment.

[0045] In order to avoid the failure of the driving motor and gears when they are not used for a long time, the software in the communication terminal device can be set to start the driving motor regularly and rotate the bracket structure for signal detection, which can not only achieve the purpose of using the driving motor and gears to work, but also ensure that the user can receive the strongest signal. In addition, when the communication terminal device located outdoors is fixed, it will be connected to the network cable and the power cable. The first driving device 30 and the second driving device 40 can work by connecting to the power cable to obtain electrical energy; in addition, the outdoor communication terminal device usually has a two-in-one wire and a network cable, which can transmit both signals and electrical energy. The first driving device 30 and the second driving device 40 can be connected to the communication terminal device through a shared wire and a two-in-one cable to transmit signals and obtain electrical energy. Moreover, the rotation angle of the bracket mechanism can be limited by setting an angle sensor on the driving motor.
