Technical Field

[0001] The utility model relates to a fixing frame, in particular to a fixing frame for fixing electronic equipment on the inner surface or outer surface of a car. Background Art

[0002] When using a car for off-road or racing, people usually need to install multiple small cameras outside the car to record the wonderful images of the activity. These cameras are generally fixed to the surface of the car through a bracket with a suction cup. The working principle of the suction cup is based on generating negative pressure: by pulling the center of the suction cup, the suction cup is changed from the original state to the pulling state, so that the suction cup is deformed, thereby increasing the volume of the sealed cavity formed between the suction cup and the surface of the car, reducing the air pressure, and the atmospheric pressure firmly presses the suction cup against the surface of the car, and then the camera is installed on the top of the bracket. However, due to the long-term tensile deformation state of the suction cup when working, coupled with the influence of other factors, after a period of use, its elastic material will gradually undergo permanent deformation. Even if it stops using, it is difficult to restore the original shape, resulting in insufficient negative pressure when it is used again and becomes the pulling state, and the suction force decreases, increasing the risk of the camera falling. Once the camera installed outside the car falls during the high-speed movement of the car, it will cause irreparable damage. Moreover, the existing bracket outside the vehicle cannot provide power for the camera device installed thereon, and the user needs to frequently remove the camera device from the bracket for charging and then install it again to continue working, which is quite cumbersome.

DETAILED DESCRIPTION

[0021] The following is a further description of the electronic device fixing bracket of the present invention in conjunction with the accompanying drawings: Embodiment 1:

[0022] See also Figures 1 to 7 The electronic device fixing frame of the utility model comprises a suction cup 1, a shell 2, a negative pressure generating device and a multi-section universal connecting rod 4, wherein the suction cup 1 is made of soft plastic or rubber, has good high temperature resistance and good resilience, the suction cup 1 has a lower surface, an upper surface and an edge, the shell 2 is made of hard plastic, and a suction cup accommodating cavity 16 is arranged at the lower part of the shell 2 for fixing and protecting the suction cup 1. The suction cup accommodating cavity 16 matches the shape and size of the suction cup 1. An electronic component cavity 17 is also arranged inside the shell 2 for installing the required electronic components, the lower edge of the shell 2 matches the edge shape of the suction cup 1, and is used to press the edge of the suction cup 1 so that an airtight contact is formed between the edge of the suction cup 1 and the surface of the object being sucked, and in order to enhance the stability of the lower edge of the shell 2 pressing the edge of the suction cup 1, two circles of annular protrusions are also arranged on the upper surface of the suction cup 1, and these two circles of annular protrusions can increase the friction between the upper surface of the suction cup 1 and the lower surface of the shell 2, and prevent the edge of the suction cup 1 from sliding into the suction cup accommodating cavity 16.

[0023] The negative pressure generating device includes a pressure rod 5, a pull rod connector 6, and a suction cup pull rod 7 arranged on the upper surface of the suction cup 1. The suction cup pull rod 7 is arranged at the center of the upper surface of the suction cup 1, and is used to apply a pulling force to the suction cup 1, change the shape of the suction cup 1, increase the volume of the cavity formed between the suction cup 1 and the surface of the object being sucked, and generate negative pressure. The suction cup pull rod 7 is provided with a male thread at one end away from the suction cup 1. The pressure rod 5 is the part that the user directly contacts when operating the suction cup, and is made of hard plastic or metal. One end of the pressure rod 5 is an operating end for the user to operate, and the other end is a lifting end for lifting the suction cup pull rod 7. The pull rod connector 6 is designed as a metal or hard plastic columnar body, which is provided with a transverse threaded through hole, which penetrates the pull rod connector 6 and matches the male thread on the suction cup pull rod 7, so as to connect the suction cup pull rod 7 in place. The two ends of the pull rod connector 6 are movably connected to the lifting end of the pressure rod 5, so that the operation of the pressure rod 5 can be transmitted to the suction cup pull rod 7, thereby achieving the stretching of the suction cup 1 and the generation of negative pressure.

[0024] When in use, the user presses the operating end of the pressure rod 5, which moves downward, and the lifting end is correspondingly pulled upward. Through this movement, the force is transmitted to the suction cup pull rod 7 through the movable pull rod connector 6. The suction cup pull rod 7 then pulls the center position of the suction cup 1 upward for a fixed distance, thereby increasing the volume of the cavity formed between the suction cup 1 and the surface of the object being sucked, thereby generating negative pressure.

[0025] When the suction cup 1 is permanently deformed due to long-term use, a fixed stroke of being pulled upward to the original position is not enough for the suction cup 1 to generate sufficient negative pressure again. At this time, the user can rotate the suction cup 1 to drive the suction cup pull rod 7 and the pull rod connecting piece 6 to rotate relative to each other, thereby reducing the relative position of the suction cup 1 and the pulling end of the pressure rod 5, so that the edge of the suction cup 1 that has been permanently deformed is close to the lower edge of the shell 2 again. After the adjustment is completed, the user presses the pressure rod 5 again. When pulling the suction cup pull rod 7, the suction cup can be deformed again to generate sufficient negative pressure, so that the bracket of the utility model is firmly adsorbed to the surface of the object being adsorbed.

[0026] In this embodiment, the connection method between the suction cup pull rod 7 and the pull rod connector 6 can also adopt another design: a female thread is set on the suction cup pull rod 7, and a corresponding male thread is set on the pull rod connector 6, so that the two can be connected by threads.

[0027] A rechargeable battery 13 is also disposed in the electronic component cavity 17 inside the shell 2. A power output interface is disposed on the shell 2 for powering external electronic devices. The power output interface also serves as a charging interface for charging the rechargeable battery 13. The rechargeable battery 13 is preferably a cylindrical lithium battery.

[0028] As shown in the figure, the housing 2 is also provided with a solar panel 12, which can continuously replenish the power of the rechargeable battery 13 inside it under suitable weather conditions. In addition, the housing 2 is also provided with a power indicator 15 for indicating the power of the battery 13, and the power indicator can be a display screen or an LED light. Embodiment 2:

[0029] See also Figure 8 The electronic device fixing frame of the utility model comprises a suction cup 1, a shell 2, a negative pressure generating device and a multi-section universal connecting rod 4, wherein the suction cup 1 is made of soft plastic or rubber, has good high temperature resistance and good resilience, the suction cup 1 has a lower surface, an upper surface and an edge, the shell 2 is made of hard plastic, and a suction cup accommodating cavity 16 is arranged at the lower part of the shell 2 for fixing and protecting the suction cup 1. The cavity matches the shape and size of the suction cup 1. An electronic component cavity 17 is also arranged inside the shell 2 for installing the required electronic components. The lower edge of the shell 2 matches the edge shape of the suction cup 1, which is used to press the edge of the suction cup 1 so that an airtight contact is formed between the edge of the suction cup 1 and the surface of the object being sucked. In order to enhance the stability of the lower edge of the shell 2 pressing the edge of the suction cup 1, two circles of annular protrusions are also arranged on the upper surface of the suction cup 1. These two circles of annular protrusions can increase the friction between the upper surface of the suction cup 1 and the lower surface of the shell 2, and prevent the edge of the suction cup 1 from sliding into the suction cup accommodating cavity 16.

[0030] The device for generating negative pressure is a manual air pump 8. The main body of the manual air pump 8 is installed in the electronic component cavity 17 in the housing 2, and its operating rod extends out of the housing 2 for easy operation by the user. The suction cup 1 is provided with an air suction port, which is connected to the manual air pump 8 through an air suction pipe. The main function of the manual air pump 8 is to remove the air in the cavity between the suction cup 1 and the surface of the object being sucked, thereby forming the necessary negative pressure to ensure that the suction cup 1 can be firmly attached to the object being sucked. Embodiment three:

[0031] like Fig. 9 As shown, the difference between Example 3 and Example 2 is that the device for generating negative pressure is an electric vacuum pump 9, which is electrically connected to the rechargeable battery 13. The suction cup 1 is provided with a vacuum port, which is connected to the electric vacuum pump 9 through a vacuum pipe. When the electric vacuum pump 9 is started, the air in the cavity between the suction cup 1 and the surface of the object being sucked is sucked out, which can form a negative pressure and ensure that the suction cup 1 is firmly attached to the object being sucked.

[0032] In order to further enhance the stability of the suction cup 1 on the object being sucked, a module for maintaining negative pressure (not shown in the figure) is also provided in the electronic component cavity 17. The module is configured to start and shut down the electric vacuum pump 9 according to a preset interval to maintain the negative pressure, such as pumping air for 5 seconds every 1 hour to ensure that the negative pressure in the cavity under the suction cup 1 is always maintained at an optimal level. In addition, the module is also equipped with an air pressure sensor that can monitor the air pressure in the cavity between the suction cup 1 and the surface of the object being sucked in real time. When the air pressure is lower than the preset threshold, the electric vacuum pump 9 will be automatically started to pump air to restore the ideal suction state.

[0033] The above describes the main features, technical principles and advantages of the utility model in combination with the embodiments. The above embodiments are not used to limit the utility model. Any modifications, equivalent substitutions and improvements made to the utility model without departing from the spirit and principles of the utility model should fall within the scope of protection of the utility model.
