As shown in
According to the novel embedded external power supply controller of the embodiment of the present invention, by providing the base assembly 10, the cover body 20 and the press-button 30, the signal converter 12 of the base assembly 10 can be stably mounted in the novel embedded external power supply controller, and the signal converter 12 can then be activated under the pressed state of the press-button 30 and send an electric signal to the external components. By providing the accommodation through cavity 21 in the cover body 20, the signal converter 12 can be accommodated in the accommodation through cavity 21, thereby being protected from external damage. By providing the stopper rib 22 on the outer wall of the cover body 20, when the novel embedded external power supply controller is assembled and used in an environment in which a relatively soft object is present, the stopper rib 22 can be inserted into the soft object, thereby increasing the contact area between the novel embedded external power controller and the external soft object and enhancing the friction between the novel embedded external power controller and the external soft object. Therefore, when the soft object is pressed by external force and is elastically deformed, the novel embedded external power supply controller can be displaced along with the external soft object without relative displacement between the two. Then when the external force is removed and the external soft object is restored to its initial shape, the novel embedded external power controller can return to its initial position with the external soft object, thereby ensuring that the novel embedded external power controller will not move relative to the surrounding soft object and thus not deviate from the mounting location when it is assembled in the external soft object. In this way, it is ensured that the novel embedded external power supply controller mounted in the soft object is stably matched with the external equipment, thereby ensuring that the performance of the novel embedded external power supply controller will not be impaired and avoiding short-circuit of the novel embedded external power supply controller when it is randomly displaced in the external soft object and thus a fire.
In the present embodiment, as shown in
Further, by arranging the outer end portions of the respective stopper ribs 22 towards the upper end of the cover body 20, the respective stopper ribs 22 can form acute angles with the outer wall of the cover body 20. Therefore, when the controller has a tendency to move in an oblique direction towards the stopper rib 22 with respect to the external soft object, each of the assembly strips can be inserted into the external soft object, thereby effectively preventing the novel embedded external power supply controller from moving in an oblique direction towards the stopper rib 22 with respect to the external soft object, which further prevents relative displacement between the novel embedded external power supply controller and the external soft object.
Further, the joints of the respective stop ribs 22 with the cover body 20 are set as rounded transitions. In this way, the joints between the respective stop ribs 22 and the cover body 20 are less likely to be cracked due to stress concentration phenomenon, thereby preventing the stop ribs 22 from breaking off the outer wall of the cover body 20. By making the outer end portions of the respective fitting strips rounded, the outer end portions of the stop ribs 22 can be prevented from being scratched with the external soft object, thereby ensuring that the external soft object around the stop rib 22 is always in good condition.
Optionally, the outer wall of the cover body 20 and the stop rib 22 can be made of a metallic material, so that when static electricity is accumulated in the novel embedded external power controller, static electricity can be transmitted to the stop ribs 22 along the outer wall of the cover body 20 and is discharged to the outside by the stop ribs 22, so that the internal static electricity of the novel embedded external power supply controller is eliminated, thereby avoiding spark generated by the static electricity accumulation inside the novel embedded external power supply controller and thus ignition of the external soft object which may cause a fire.
In this embodiment, as shown in
Further, the respective stop ribs 22 is disposed on the outer wall of the opposite sides of the cover body 20 in parallel and evenly spaced apart from each other, and a buffering through groove 23 is formed between two adjacent stop ribs 22. Thus, since the respective stop ribs 22 is arranged parallel to each other and equally spaced, the volume and mass of the outer soft object accommodated within the buffering through groove 23 formed by the respective stop ribs 22 on the outer wall of the opposite sides of the cover body 20 can be kept consistent, and the forces exerted by the external soft object on the outer walls of the opposite sides of the cover body 20 are consistent, thereby avoiding inconsistent external forces exerted on the outer walls of the opposite sides and thus deflection of the cover body 20 towards the side subjected to larger force, which further improves the stopping performance of the novel embedded external power controller with the stop rib 22 in the external soft object.
Preferably, the number of the stop ribs 22 provided on each of the outer walls of the opposite sides of the cover body 20 is seven, so that a balance is achieved between the mounting difficulty of the mounting ribs 22 and the stopping performance of the novel embedded external power controller with the stop rib 22 in the external soft object, which avoids significant rise of overall production cost of the novel embedded external power controller due to the excessive number of the stop ribs 22 and prevents insufficient stopping performance of the stop ribs 22 which would otherwise cause the novel embedded external power supply controller to move easily relative to the external soft object.
Further, by setting the stop ribs 22 as elastic members, the stop ribs 22 are prevented from being subjected to a sudden impact force and being broken when they contact a hard object, and long-term stable serviceability of power controllers in complex conditions is enhanced.
Preferably, the novel embedded external power supply controller has a vertical overall size of 25 to 30 mm. Specifically, the vertical integrated overall size of the novel embedded external power controller may be 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, or 30 mm.
In the present embodiment, as shown in
Further, by making each of the protruding knobs 31 corresponding to and matching with one of the limit holes 213 and leaving a proper gap between the protruding button 31 and the limit hole 213, a moving connection of the press-button 30 with the cover body 20 can be achieved. Thus the press-button 30 can be rotated relative to the cover body 20 and contact the trigger terminal 112 of the signal converter 12 to effect triggering of the signal converter 12.
Further, by extending the lower end of the press-button 30 downward to form the trigger portion 32, the trigger portion 32 can abut against the trigger terminal 112 of the signal converter 12 during the rotation of the press-button 30 relative to the cover body 20 and exert certain pressure on the trigger terminal 112. The signal converter 12 can convert the pressure signal into an electric signal after sensing the pressure signal, and simultaneously transmit the electric signal to the external device, thus achieving control of the external device via pressing the press-button 30.
In this embodiment, as shown in
Further, by mounting the mounting platform 11 on the base 13, a secure attachment of the mounting platform 11 within the base assembly 10 is thus achieved. By fixing the signal converter 12 to the mounting platform 11, the signal converter 12 can be prevented from being directly mounted to the base 13, so that a more sufficient assembly space is obtained. The lower edge of the cover body 20 is fixedly connected to the upper edge of the base 13, and the base 13 and the mounting platform 11 are both located in the accommodation through cavity 21, so that the base 13 and the mounting platform 11 are effectively protected by the cover body 20.
In the present embodiment, as shown in
Further, by fitting the outer edge of the mounting platform 11 into the assembling step 15 which is fixed to the upper end of the support column 14 of the base 13, the assembling step 15 is easier to form, and fitting and operation between the outer edge of the mounting platform 11 and the assembling step 15 is simple. In this way, a simple and stable connection between the mounting platform 11 and the base 13 via assembling is realized.
Preferably, there are three support columns 14, in which two support columns 14 correspond to one side of the mounting platform 11, and the other support column 14 corresponds to the opposite side of the mounting platform 11. The three support columns 14 form a solid triangular relationship and provide sufficient support for the mounting platform 11. At the same time, the number of the support columns 14 is limited to three, which avoids excessive number of the support columns 14 and thus rise of high manufacturing cost of the base assembly 10. Also, the number of the support columns 14 is also prevented from being too small, which would otherwise lead to unstable support of the base 13 to for the mounting platform 11.
Further, by fixedly connecting the lower end of each of the limit buckles 16 to the upper end of the base 13, the outer edge of the mounting platform 11 is embedded in the engagement groove 17 of each of the limit buckles 16. This further improves the connection stability of the mounting platform 11 and the base 13.
Preferably, there are two limit buckles 16, and the two limit buckles 16 respectively correspond to the two sides of the mounting platform 11 not fitted with the support columns 14. In this way, a stable connection between the peripheral outer edge of the mounting platform 11 and the base 13 is achieved through the support columns 14 and the limit buckles 16, thereby ensuring safety of the signal converter 12 mounted on the mounting platform 11.
In this embodiment, as shown in
Further, by engaging the limit ribs 18 with the limit engagement grooves 19, on one hand, precise seamless docking is achieved between the base 13 and the cover body 20, thereby ensuring that external impurities do not pass through the gap between the base 13 and the cover body 20 to enter into the interior of the novel embedded external power supply controller and affect normal operation of the electronic components. On the other hand, it facilitates stable assembly between the base 13 and the cover body 20.
Further, by engaging the limit buckles 111 in the respective limit recesses 212, the base 13 and the cover body 20 can be further stably connected, and it is ensured that the cover body 20 and the base 13 would not be separated by the pulling force from the outside.
In the present embodiment, as shown in
Further, by providing the transmission pin 113 at the lower end of the signal converter 12 and electrically connecting the transmission pin 113 to the electrical connection line 115, when the press-button 30 triggers the signal converter 12, the signal converter 12 converts the pressure signal given by the pressure switch into an electric signal, which is then transmitted to the electrical connection line 115 through the transmission pin 113, and after that the electric signal is transmitted by the electrical connection line 115 to a related external device.
Preferably, there are two signal converters 12, and there are also two trigger portions 32 of the pressure-sensitive button 30. In this way, by providing two signal converters 12, it is realized that different signal converters 12 are triggered to output different electric signals, and then the external devices that are electrically connected to the novel embedded external power supply controller are sent different instructions.
In this embodiment, as shown in
Further, the lower end of the electrical connector 116 can also be provided with a connecting pin 117, and the connecting pin 117 is electrically connected to the electrical connecting line 115. In this manner, the electrical connector 116 is electrically connected to the electrical connection line 115. Further, the electrical connector 116 is specifically a USB input port. Therefore, an external device such as a mobile terminal can be electrically connected to the novel embedded external power supply controller through the USB input port, and the novel embedded external power supply controller can be electrically connected to the external power supply, so that the external power supply can be used to provide power for consumer devices such as mobile terminals through the novel embedded external power controller.
In this embodiment, as shown in
Further, by providing the fixed rim 25, the fixed rim 25 can be fitted with the surface layer of the external soft object, thus further limiting the relative movement of the novel embedded external power supply controller relative to external soft object. At the same time, since the outer wall of the cover body 20 is further provided with a plurality of stop ribs 22, the fixed rim 25 can cooperate with the stop ribs 22, so that the novel embedded external power supply controller is firmly fixed to the external soft object, which further enhances the stability of the novel embedded external power controller in the external soft object.
The above disclosed embodiments are merely preferred embodiments of the present invention, and certainly do not limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the present invention for patent application still fall within the scope of the present invention.
