Referring to fig. 1 and 2, an emergency power supply device 100 according to a preferred embodiment of the present invention includes a power supply housing 110, a conductive member 120, an energy storage element (not shown) fixing magnet 130, and a circuit board 140.

The power supply case 110 serves as a housing and is generally molded from a material such as resin or plastic. The conductive member 120, the energy storage element (not shown) fixing magnet 130 and the circuit board 140 may be accommodated in the power supply housing 110. The power supply housing 110 includes an upper shell 111 and a flexible glue bottom plate 112. One side of the upper case 111 is opened, and the soft rubber bottom plate 112 is installed at the upper case 111 and covers the opening of the upper case 111.

The upper shell 111 is typically a hard shell structure molded from plastic or resin. In order to facilitate taking and placing the emergency power supply 100, in this embodiment, the side wall of the upper case 111 is provided with an anti-slip rib 1111. The slip ribs 1111 can increase the friction when the operator grips the power supply housing 110. Meanwhile, the anti-slip ribs 1111 may increase the surface area of the upper case 111, thereby improving the heat dissipation efficiency of the power supply case 110.

The soft rubber base plate 112 may be soft molded from ordinary rubber, silica gel, or TPU (Thermoplastic polyurethane elastomers). Specifically, in this embodiment, the soft rubber bottom plate 112 is formed by molding TPU soft rubber. The soft rubber bottom plate 112 has better flexibility. Therefore, on the premise of ensuring the hard plate body structure, the thickness of the soft rubber bottom plate 112 can be significantly reduced compared with the traditional hard plate body structure. Generally, the wall thickness of a common hard shell structure needs to reach more than 2 millimeters to ensure the required strength; the soft rubber bottom plate 112 can be 0.8 mm thick and is not easy to damage.

The energy storage element can be an energy storage structure such as a lithium battery cell and a lead-acid battery cell, and can store electric energy in a chemical energy mode and convert the chemical energy into the electric energy again. The circuit board 140 is electrically connected to the energy storage element, and can perform switching, transforming, and current limiting control, so that the energy storage element can smoothly realize charging and discharging.

The conductive member 120 is disposed on the power supply housing 110. The conductive member 120 is used to conduct the stored electrical energy from the energy storage element, so the conductive member 120 is generally formed of a good conductor such as copper, aluminum, or an alloy thereof. The conductive member 120 may have a plate-like, sheet-like, or columnar structure. The electric equipment powered by the emergency power supply device 100 is usually provided with a power receiving structure (not shown) adapted to the conductive member 120. Specifically, in the present embodiment, the conductive member 120 is a columnar structure.

The fixed magnet 130 is accommodated in the power supply housing 110 and is disposed on the flexible glue base plate 112. The fixed magnet 130 may be a permanent magnet or an electromagnet. Specifically, in the present embodiment, the fixed magnet 130 is a permanent magnet. For example, neodymium-iron-boron magnets, samarium-cobalt magnets, oxide magnets, and the like. The permanent magnet has the advantages of convenience in installation, low cost and the like, and the cost of the emergency power supply device 100 can be reduced.

When the emergency power supply device 100 is used, the power supply housing 110 may be attached to a metal casing of an electric device. Usually, the flexible glue base plate 112 contacts with the electric equipment. By the attraction of the fixing magnet 130, the power supply housing 110 can be attracted to the electric device, thereby achieving the attraction fixation of the emergency power supply device 100. Therefore, the emergency power supply device 100 can liberate both hands of an operator during use, and is more convenient to use.

Specifically, in the present embodiment, the soft rubber bottom plate 112 is provided with an avoiding hole 1121, and the conductive member 120 is located in the power supply housing 110 and is opposite to the avoiding hole 1121. Therefore, when the flexible glue bottom plate 112 is attached to the outer wall of the electrical equipment, the conductive member 120 can be electrically connected to the electrical equipment through the avoiding hole 1121. Moreover, since the conductive member 120 is sandwiched between the flexible glue bottom plate 112 and the electrical equipment and is not exposed, the risk that the conductive member 120 is touched by mistake is reduced, thereby improving the reliability of the electrical connection between the emergency power supply device 100 and the electrical equipment.

In addition, the soft rubber bottom plate 112 is soft, so that the abrasion to the shell of the electric equipment can be avoided. In addition, the friction factor of the surface of the bottom plate 112 made of the soft rubber material is large, so that the friction force between the power supply housing 110 and the electric equipment can be increased. Therefore, even if there is a large vibration in the use environment, the emergency power supply 100 is not caused to slip off from the electric equipment.

As mentioned above, since the flexible glue base plate 112 has better flexibility, compared with the conventional hard plate structure, the thickness of the flexible glue base plate 112 can be significantly reduced on the premise of ensuring that the flexible glue base plate is not easy to be damaged. Thus, the magnetic field of the fixed magnet 130 can penetrate the power supply housing 110 more easily, so that the fixed magnet 130 with smaller magnetic flux can be selected to perform the function of adsorption and fixation, thereby avoiding the cost increase caused by using a magnet with larger magnetic flux.

In this embodiment, the outer surface of the soft rubber bottom plate 112 is a plane.

When the emergency power supply device 100 is electrically connected to the electric equipment, the outer surface of the soft rubber bottom plate 112 abuts against the outer wall of the electric equipment. Therefore, the outer surface of the soft rubber bottom plate 112 is set to be of a plane structure, and the plane structure is matched with the plane structure of the outer wall of the electric equipment, so that plane support can be achieved between the emergency power supply device 100 and the electric equipment, the supporting stability is better, the emergency power supply device 100 is effectively prevented from shaking, warping, deflecting and the like when being electrically connected, and the reliability of electrical connection is guaranteed.

In this embodiment, there are a plurality of fixed magnets 130, and the positions of the fixed magnets 130 on the flexible glue base 112 are adjustable.

The size and shape of the electric equipment are different according to different types or models. Through adjusting the distribution position of the fixed magnets 130 on the soft rubber bottom plate 112, the action site of the magnetic attraction force can be adjusted for different electric devices, so that the attraction between the emergency power supply device 100 and the electric devices is firmer.

Further, in the present embodiment, a plurality of elastic slots 1122 are formed on the inner wall of the flexible glue base plate 112, and each of the fixed magnets 130 can be received and held in any of the elastic slots 1122.

The elastic slot 1122 may be formed by surrounding criss-cross ribs (not shown) on the inner wall of the flexible glue base plate 112. The ribs and the soft rubber bottom plate 112 are integrally formed and are also made of flexible materials, so that the clamping groove structure formed by enclosing the ribs has elasticity, and the length and the width of the clamping groove structure can be elastically changed within a certain range. The elastic slot 1122 can perform a better limiting and fixing function on the fixed magnet 130. When the position of the fixed magnet 130 needs to be adjusted, the soft rubber bottom plate 112 is opened first, and the fixed magnet 130 is buckled out of one of the elastic slots 1122 and then clamped into the other elastic slot 1122.

Further, in this embodiment, a plurality of buckles 1124 are circumferentially disposed on an edge of the soft rubber base plate 112, and the soft rubber base plate 112 is clamped to the upper case 111 through the plurality of buckles 1124. Therefore, when the position of the fixed magnet 130 needs to be adjusted, the soft rubber bottom plate 112 is pulled off from the upper shell 111, and the soft rubber bottom plate 112 is clamped into the upper shell again after the position adjustment is completed, so that the assembly and disassembly are more convenient.

In this embodiment, the soft rubber bottom plate 112 is provided with a positioning hole 1123.

Specifically, the electric device may be provided with a corresponding positioning protrusion (not shown). When the emergency power supply device 100 is electrically connected with the electric equipment, the positioning protrusion can be matched with the positioning hole 1123, so that the emergency power supply device 100 is further prevented from transversely moving or swinging relative to the electric equipment, and the reliability of the electrical connection is further ensured.

As described above, in the present embodiment, the fixed magnet 130 is a permanent magnet. Obviously, in other embodiments, the fixed magnet 130 may also be an electromagnet. The electromagnet comprises an electric core and a coil, the coil is electrically connected with the energy storage element through a circuit board 140, and a switch for controlling the on-off of the coil is arranged on the circuit board 140.

When the coil is energized, the fixed magnet 130 can generate magnetic force, and when the coil is de-energized, the magnetic force of the fixed magnet 130 disappears. When the emergency power supply device 100 supplies power, the switch is turned on to similarly energize the coil, thereby achieving attraction with the electric equipment. After the emergency power supply 200 is used, the switch is switched to cut off the power of the coil. At this time, the magnetic force of the fixed magnet 130 disappears, and the emergency power supply device 100 cannot be magnetically attached to the electric device, so that taking away the emergency power supply device 100 will not need to overcome the magnetic attachment force, and the operation is more convenient.

Above-mentioned emergency power supply unit 100, when using, pastes the metal casing in the consumer with flexible glue bottom plate 112 earlier, through the adsorption of fixed magnet 130, alright make power casing 110 adsorb on the consumer to realize that emergency power supply unit 100's adsorption is fixed. The soft rubber bottom plate 112 is soft, so that abrasion to the shell of the electric equipment can be avoided. In addition, the friction factor of the surface of the soft rubber bottom plate 112 is large, so that the friction force between the power supply shell 110 and the electric equipment can be increased. Even if there is large vibration in the use environment, the emergency power supply device 100 will not be slipped off from the electric equipment. Further, the suction fixation by the fixed magnet 130 frees both hands of the operator. Therefore, the emergency power supply device 100 is more convenient to use.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
