Description

Technical Field

[0001] The present invention relates to the technical field of non-motor vehicle on-vehicle sound amplification, and particularly to a non-motor vehicle on-vehicle portable mobile phone sound amplification device. Background Art

[0002] During the driving of non-motor vehicles, various noises may exist in the surrounding area, such as the friction sound between the tires and the road surface, the wind sound, etc. These noises will interfere with the driver's reception of the mobile phone sound, resulting in the original volume of the mobile phone not being able to meet the requirements. In order to clearly hear the music, navigation voice, call sound, etc. played on the mobile phone during driving, the driver usually chooses to install an on-vehicle portable mobile phone amplifier on the non-motor vehicle.

[0003] The on-vehicle portable mobile phone amplifiers currently used in the market can be divided into two categories: wireless connection type amplifiers and wired connection type amplifiers. The wireless connection type amplifier is paired with the mobile phone through wireless technologies such as Bluetooth, and the user can move freely within a certain range during use. The wired connection type amplifier is directly connected to the mobile phone through a physical cable, which can ensure the stability and quality of sound transmission during use.

[0004] However, the above wireless connection type amplifier and wired connection type amplifier still have deficiencies during use. For example, the wireless signal in the wireless connection type amplifier may be interfered by other electronic devices, resulting in problems such as sound interruption and stuttering. For example, the connection cable in the wired connection type amplifier may be affected by the bumps and vibrations of the non-motor vehicle, resulting in problems such as cable loosening and detachment. In addition, there are differences in audio output interfaces, Bluetooth protocols, etc. among different brands and models of mobile phones. The above amplifiers may not be able to perfectly adapt to all mobile phones, resulting in some mobile phones being unable to use the sound amplification function normally, or compatibility problems occurring during use. In addition, the above amplifiers also have problems such as the need for regular charging, high production costs, complex function use, and inability to fix the mobile phone. Therefore, a non-motor vehicle on-vehicle portable mobile phone sound amplification device that can ensure the sound transmission quality and does not require Bluetooth or cable connection is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages such as easy occurrence of sound interruption, cable loosening, and compatibility problems caused by Bluetooth and cable connections in the prior art, and to propose a non-motor vehicle on-vehicle portable mobile phone sound amplification device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A non-motor vehicle-mounted portable mobile phone sound amplification device, comprising a handlebar fixing clip and a damping adjustment frame arranged outside the handlebar fixing clip. The output end of the damping adjustment frame is fixedly connected with a placement frame for placing a mobile phone. The back of the placement frame is fixedly connected with a transparent heat dissipation plate. The front of the placement frame is hinged with a magnetic attraction frame that can be closed outside it. The inner side of the magnetic attraction frame is fixedly connected with an elastic rubber frame. The side of the elastic rubber frame away from the magnetic attraction frame is fixedly connected with a transparent touch screen. The bottom of the placement frame is provided with a physical sound amplification mechanism for sound amplification. The physical sound amplification mechanism includes a base body fixedly connected to the outer bottom of the placement frame and a rectangular sound collection cavity opened at the inner bottom of the placement frame. A tapered sound guiding cavity and a horn-shaped sound amplification cavity that are communicated with each other are opened inside the base body. The tapered sound guiding cavity is communicated with the bottom of the rectangular sound collection cavity, and the horn-shaped sound amplification cavity extends to the outside of the base body. After the mobile phone placed inside the placement frame is fixed by the pressing of the transparent touch screen, the sound played by the mobile phone can be collected through the rectangular sound collection cavity, gathered through the tapered sound guiding cavity, and amplified through the horn-shaped sound amplification cavity in sequence, so as to realize the physical sound amplification of the sound played by the mobile phone, and make the sound played by the mobile phone be amplified without using a power supply.

[0008] An auxiliary fixing mechanism for fixing the mobile phone is arranged inside the placement frame. The auxiliary fixing mechanism includes a bottom support plate located above the rectangular sound collection cavity and symmetrically arranged side clamping plates. Elastic rubber blocks are arranged on the inner sides of the bottom support plate and the side clamping plates. The inner side of the bottom support plate and the symmetric side clamping plates can cooperate to fix the mobile phone together, which can prevent the mobile phone from jolting and vibrating during driving, and can reduce the squeezing and fixing effect of the transparent touch screen on the mobile phone screen.

[0009] The above technical solution further includes:

[0010] The handlebar fixing clip can be fixed outside the handle of the non-motor vehicle, and the damping adjustment frame can adjust the height and angle of the placement frame.

[0011] The transparent heat dissipation plate can be attached to the back of the mobile phone to assist in heat dissipation of the mobile phone, and the transparent touch screen can be attached to the mobile phone screen to operate the mobile phone normally.

[0012] The inner walls of the rectangular sound collection cavity, the tapered sound guiding cavity, and the horn-shaped sound amplification cavity are smooth; the smooth inner walls can reduce reflection and air friction loss.

[0013] A telescopic sound collecting tube fixedly connected to the bottom of the bottom support plate and fixedly communicating with the top of the rectangular sound collecting cavity is provided. A linkage member for linking the bottom support plate and the side clamping plates is arranged inside the placement frame body, and a locking member for locking the bottom support plate and the side clamping plates is arranged inside the magnetic attraction frame body. The telescopic sound collecting tube can ensure that the sound played by the mobile phone enters the inside of the rectangular sound collecting cavity.

[0014] The linkage member includes a vertical chute and a horizontal chute which are opened on the outer side of the transparent heat dissipation plate and communicate with each other. A vertical connecting frame fixedly connected to the bottom support plate is slidably connected inside the vertical chute. A return spring for assisting the bottom support plate and the side clamping plates to reset is fixedly connected between the vertical connecting frame and the vertical chute. Two horizontal connecting frames fixedly connected to the side clamping plates are symmetrically and slidably connected inside the horizontal chute. The vertical connecting frame and the bottom support plate slide together, and the horizontal connecting frame and the side clamping plates slide together.

[0015] A meshing gear is rotatably connected at the communicating part of the vertical chute and the horizontal chute. A vertical tooth group meshing with the meshing gear is fixedly connected to the inner side of the vertical connecting frame. A horizontal tooth group meshing with the meshing gear is fixedly connected to the outer side of the horizontal connecting frame. A cross sealing plate located outside the meshing gear, the vertical tooth group and the horizontal tooth group is fixedly connected to the outside of the communicating part of the vertical chute and the horizontal chute. When the mobile phone is placed on the bottom support plate, the gravity of the mobile phone can drive the bottom support plate to move downward, causing the meshing gear to rotate and drive the two side clamping plates to approach each other and clamp the mobile phone, thereby realizing the primary clamping of the mobile phone.

[0016] The locking member includes T-shaped grooves symmetrically opened on the outer side of the placement frame body, locking blocks symmetrically fixedly connected to the inner side of the magnetic attraction frame body, and vertical connecting rods symmetrically fixedly connected to the bottom of the bottom support plate. The bottom side of the locking block is provided with an abutting inclined surface, and the vertical connecting rod passes through the T-shaped groove and locking grooves are uniformly opened on the outer side thereof. When the magnetic attraction frame body is closed, the abutting inclined surface on the locking block can abut against the locking groove to make the vertical connecting rod move downward, so that the bottom support plate continues to move downward and drives the two side clamping plates to continue to clamp the mobile phone, thereby realizing the secondary clamping of the mobile phone.

[0017] The present invention has the following beneficial effects:

[0018] 1. The handlebar fixing clip in the present invention can be fixed outside the handle of a non-motor vehicle. The damping adjustment frame can adjust the height and angle of the placement frame body. The transparent heat dissipation plate can be attached to the back of the mobile phone to assist in heat dissipation of the mobile phone. The transparent touch screen can be attached to the screen of the mobile phone to operate the mobile phone normally.

[0019] 2. In the present invention, by closing the magnetic frame, the transparent touch screen can be tightly pressed against the outside of the mobile phone to fix the mobile phone. At the same time, the placement frame and the magnetic frame wrapped around the outside of the mobile phone can play the role of wind and rain protection.

[0020] 3. In the present invention, the sound played by the mobile phone can be successively collected by the rectangular sound collecting cavity, aggregated by the conical sound guiding cavity, and amplified by the horn-shaped sound amplifying cavity to achieve physical amplification of the sound played by the mobile phone. This enables the sound played by the mobile phone to be amplified without using power, with low production costs, simple function use, no need to use Bluetooth connection and cable connection, and is suitable for fixing and amplifying different brands and models of mobile phones.

[0021] 4. When placing the mobile phone in the present invention, the mobile phone can be initially clamped through the gravity of the mobile phone and the linkage between the bottom support plate and the side clamping plate. When closing the magnetic frame, the mobile phone can be secondarily clamped through the abutting force and locking force between the abutting inclined surface and the abutting locking groove. That is, while reducing the squeezing and fixing force of the transparent touch screen on the mobile phone screen, it can prevent the mobile phone from jolting and vibrating during driving, which may affect the amplification quality of the physical sound amplification mechanism.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] As Figures 1-4 shown, a non-motor vehicle-mounted portable mobile phone sound amplification device proposed by the present invention includes a handlebar fixing clip 1 and a damping adjustment frame 2 arranged outside the handlebar fixing clip 1. The handlebar fixing clip 1 can be fixed outside the handle of the non-motor vehicle, and the damping adjustment frame 2 can adjust the height and angle of the placing frame 3. The specific structures and connection methods of the handlebar fixing clip 1 and the damping adjustment frame 2 both adopt existing technologies. Therefore, they are not described in detail in this embodiment;

[0035] The output end of the damping adjustment frame 2 is fixedly connected with a placing frame 3 for placing a mobile phone. The back of the placing frame 3 is fixedly connected with a transparent heat dissipation plate 4, and the transparent heat dissipation plate 4 can be attached to the back of the mobile phone to assist the mobile phone in dissipating heat. The front of the placing frame 3 is hinged with a magnetic frame 5 that can be closed outside it. The inner side of the magnetic frame 5 is fixedly connected with an elastic rubber frame 6, and one side of the elastic rubber frame 6 away from the magnetic frame 5 is fixedly connected with a transparent touch screen 7. The transparent touch screen 7 can be attached to the screen of the mobile phone to operate the mobile phone normally. By closing the magnetic frame 5, the transparent touch screen 7 can be pressed against the outside of the mobile phone to fix the mobile phone. At the same time, the placing frame 3 and the magnetic frame 5 wrapped outside the mobile phone can play a role in protecting against wind and rain;

[0036] A physical sound amplification mechanism 80 for sound amplification is provided at the bottom of the placement frame 3. The physical sound amplification mechanism 80 includes a base body 81 fixedly connected to the outer bottom of the placement frame 3 and a rectangular sound collection cavity 82 opened at the inner bottom of the placement frame 3. A tapered sound guiding cavity 83 and a horn-shaped sound amplification cavity 84 communicating with each other are opened inside the base body 81. The tapered sound guiding cavity 83 communicates with the bottom of the rectangular sound collection cavity 82, and the horn-shaped sound amplification cavity 84 extends to the outside of the base body 81. The inner walls of the rectangular sound collection cavity 82, the tapered sound guiding cavity 83, and the horn-shaped sound amplification cavity 84 are smooth. The smooth inner walls can reduce reflection and air friction loss. The sound emitted from the audio output port at the bottom of the mobile phone can enter the inside of the tapered sound guiding cavity 83 through the rectangular sound collection cavity 82. The sound entering the inside of the tapered sound guiding cavity 83 is gathered and then enters the inside of the horn-shaped sound amplification cavity 84 for amplification, thus realizing the physical sound amplification of the mobile phone.

[0037] The working principle of this embodiment: First, fix it outside the handle of the non-motor vehicle through the handlebar fixing clip 1, then adjust the height and angle of the placement frame 3 through the damping adjustment frame 2. Subsequently, open the magnetic attraction frame 5 and place the mobile phone inside the placement frame 3, and then close the magnetic attraction frame 5 to make the transparent touch screen 7 compress the elastic rubber frame 6 and press tightly against the outside of the mobile phone. The transparent touch screen 7 pressing tightly against the outside of the mobile phone can fix the position of the mobile phone, and the placement frame 3 and the magnetic attraction frame 5 wrapped around the outside of the mobile phone can play the role of wind and rain protection;

[0038] After the mobile phone placed inside the placement frame 3 is fixed by the pressing of the transparent touch screen 7, the sound emitted from the audio output port at the bottom of the mobile phone can enter the inside of the tapered sound guiding cavity 83 through the rectangular sound collection cavity 82. The sound entering the inside of the tapered sound guiding cavity 83 is gathered and then enters the inside of the horn-shaped sound amplification cavity 84 for amplification. In this way, the physical sound amplification of the mobile phone can be realized.

[0039] The main difference between this embodiment and the prior art is that: In this embodiment, the sound played by the mobile phone can be successively collected through the rectangular sound collection cavity 82, gathered through the tapered sound guiding cavity 83, and amplified through the horn-shaped sound amplification cavity 84 to realize the physical sound amplification of the sound played by the mobile phone, so that the sound played by the mobile phone can be amplified without using power, with low production cost, simple function use, without using Bluetooth connection and cable connection, and is suitable for the fixation and sound amplification of mobile phones of different brands and models.

[0040] Embodiment Two

[0041] Such as Figures 5-9As shown, based on the first embodiment, an auxiliary fixing mechanism 90 for fixing the mobile phone is provided inside the placement frame 3. The auxiliary fixing mechanism 90 includes a bottom support plate 91 located above the rectangular sound collecting cavity 82 and symmetrically arranged side clamping plates 92. Elastic rubber blocks 93 are provided on the inner sides of the bottom support plate 91 and the side clamping plates 92. The inner side of the bottom support plate 91 and the symmetric side clamping plates 92 can cooperate to fix the mobile phone. While preventing the mobile phone from jolting and vibrating during driving, it can reduce the squeezing and fixing effect of the transparent touch screen 7 on the mobile phone screen. The bottom of the bottom support plate 91 is fixedly connected to a telescopic sound collecting tube 94 fixedly communicated with the top of the rectangular sound collecting cavity 82. The setting of the telescopic sound collecting tube 94 can ensure that the sound played by the mobile phone enters the inside of the rectangular sound collecting cavity 82;

[0042] A linkage member 950 for linking the bottom support plate 91 and the side clamping plates 92 is provided inside the placement frame 3. The linkage member 950 includes a vertical chute 951 and a horizontal chute 952 that are opened on the outer side of the transparent heat dissipation plate 4 and communicate with each other. A vertical connecting frame 953 fixedly connected to the bottom support plate 91 is slidably connected inside the vertical chute 951. The vertical connecting frame 953 and the bottom support plate 91 slide together. A return spring 954 for assisting the bottom support plate 91 and the side clamping plates 92 to reset is fixedly connected between the vertical connecting frame 953 and the vertical chute 951. Horizontally connecting frames 955 fixedly connected to the side clamping plates 92 are symmetrically slidably connected inside the horizontal chute 952. The horizontally connecting frames 955 and the side clamping plates 92 slide together. A meshing gear 956 is rotatably connected at the communicating portion of the vertical chute 951 and the horizontal chute 952. A vertical tooth group 957 meshing with the meshing gear 956 is fixedly connected to the inner side of the vertical connecting frame 953. A horizontal tooth group 958 meshing with the meshing gear 956 is fixedly connected to the outer side of the horizontal connecting frame 955. When the mobile phone is placed on the bottom support plate 91, the gravity of the mobile phone can drive the bottom support plate 91, the vertical connecting frame 953 and the vertical tooth group 957 to move downward and compress the return spring 954, so that the meshing gear 956 rotates and drives the two side clamping plates 92 to approach each other to clamp the mobile phone, thereby realizing the initial clamping of the mobile phone. A cross-shaped sealing plate 959 located outside the meshing gear 956, the vertical tooth group 957 and the horizontal tooth group 958 is fixedly connected to the outside of the communicating portion of the vertical chute 951 and the horizontal chute 952;

[0043] Inside the magnetic attraction frame body 5, there is a locking member 960 for locking the bottom support plate 91 and the side clamping plates 92. The locking member 960 includes T-shaped grooves 961 symmetrically opened on the outer side of the placing frame body 3, locking blocks 962 symmetrically and fixedly connected to the inner side of the magnetic attraction frame body 5, and vertical connecting rods 963 symmetrically and fixedly connected to the bottom of the bottom support plate 91. The bottom side of the locking block 962 is provided with an abutting inclined surface 964. The vertical connecting rod 963 passes through the T-shaped groove 961 and locking grooves 965 are evenly opened on the outer side. When the magnetic attraction frame body 5 is closed, the abutting inclined surface 964 on the locking block 962 can abut against the locking grooves 965 to make the vertical connecting rod 963 move downward, so that the bottom support plate 91 continues to move downward and drives the side clamping plates 92 on both sides to continue clamping the mobile phone, thereby realizing the secondary clamping of the mobile phone.

[0044] The working principle of this embodiment: On the basis of Embodiment 1, when the mobile phone is placed on the bottom support plate 91, the gravity of the mobile phone will drive the bottom support plate 91, the vertical connecting frame 953 and the vertical gear set 957 to move downward and compress the return spring 954. The downward moving vertical gear set 957 will drive the meshing gear 956 to rotate clockwise, and the clockwise rotating meshing gear 95 will drive the horizontal gear sets 958, the horizontal connecting frames 955 and the side clamping plates 92 on both sides to approach each other until the approaching side clamping plates 92 clamp the mobile phone, so that the primary clamping of the mobile phone can be realized.

[0045] On the basis of Embodiment 1, when the magnetic attraction frame body 5 is closed, the locking block 962 following the movement of the magnetic attraction frame body 5 will abut against the locking grooves 965 through the abutting inclined surface 964 on its outer side, so that the vertical connecting rod 963 drives the bottom support plate 91 to continue to move downward, and the continuously downward moving bottom support plate 91 will drive the side clamping plates 92 on both sides to continue clamping the mobile phone until the magnetic attraction frame body 5 is completely closed, that is, the locking block 962 completely enters the inside of the locking grooves 965, so that the secondary clamping of the mobile phone can be realized.

[0046] The main difference between this embodiment and the prior art is that: when placing the mobile phone in this embodiment, the primary clamping of the mobile phone can be realized through the gravity of the mobile phone and the linkage between the bottom support plate 91 and the side clamping plates 92. When closing the magnetic attraction frame body, the secondary clamping of the mobile phone can be realized through the abutting force and locking force between the abutting inclined surface 964 and the abutting locking grooves 965. While reducing the extrusion and fixing force of the transparent touch screen 7 on the mobile phone screen, it can prevent the mobile phone from jolting and vibrating during driving, which affects the sound amplification quality of the physical sound amplification mechanism 80.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
