DETAILED DESCRIPTION
[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position. Example 1
[0031] A portable vehicle-mounted emergency power supply includes a battery 1, a limit frame 2, a support plate 3, a force rod 4, a connecting wire 5, a universal ball rod 6, a first spring 7, an elastic bottom block 8 and a positioning mechanism 9, please refer to Figure 1-Figure 4 As shown, a battery 1 is placed on the top of the support plate 3, and a connection wire 5 is symmetrically connected to the lower front side of the battery 1. The tail ends of the connection wires 5 are slidably penetrated through the support plate 3 and clamped to the rear side of the battery 1. The limit frame 2 is symmetrically connected between the left and right sides of the top of the support plate 3. The battery 1 is located in the limit frame 2. A force-bearing rod 4 is installed between the tops of the limit frames 2 on the front and rear sides by bolt connection. The left and right sides of the top of the support plate 3 are symmetrically slidably connected to the elastic bottom block 8. The elastic bottom block 8 is composed of an elastic member and a round block. The parts are connected to the support plate 3, the round block is connected to the tail end of the elastic part, the tops of the four elastic bottom blocks 8 are rotatably connected with universal ball rods 6, the tops of the four universal ball rods 6 are rotatably connected to the bottom of the battery 1, and a first spring 7 is connected between the upper part of the universal ball rod 6 and the top of the elastic bottom block 8. When the battery 1 is placed and carried, the universal ball rod 6 can buffer and reduce shock to the battery 1 through the first spring 7. A positioning mechanism 9 is arranged on the rear side of the support plate 3. When the positioning mechanism 9 is in operation, the positioning mechanism 9 can realize the connection wire 5 for releasing and retrieving the wire.
[0032] The positioning mechanism 9 includes a positioning wheel 91, a servo motor 92 and a reversing gear 93, see Figure 3 and Figure 4 As shown, a group of positioning wheels 91 are rotatably connected on both sides of the rear of the support plate 3. The number of each group of positioning wheels 91 is two, between the left side connection wire 5 and the two left side positioning wheels 91, and between the right side connection wire 5 and the two right side positioning wheels 91. When the positioning wheels 91 rotate, the positioning wheels 91 can drive the connection wire 5 to move. A reversing gear 93 is fixedly connected to the center position of the bottom circle of each group of two positioning wheels 91. The two reversing gears 93 on each group of positioning wheels 91 are meshed. A servo motor 92 is installed in the middle of the rear of the support plate 3 by bolt connection. The output shaft of the servo motor 92 and the upper part of the shaft of each group of right side positioning wheels 91 are driven by a synchronous belt assembly.
[0033] First, hold the force-bearing rod 4 and pull the limit frame 2 to move upward. The limit frame 2 moves upward and drives the elastic bottom block 8 to move upward through the support plate 3. The elastic bottom block 8 moves upward and drives the universal ball rod 6 to move upward. The universal ball rod 6 moves upward and drives the battery 1 to move upward, and the battery 1 can be placed on the car for carrying. When the support plate 3 is placed on the car, the support plate 3 contacts the car and stops moving. Due to the action of the elastic bottom block 8 and the first spring 7, the universal ball rod 6 can buffer and reduce shock to the battery 1. Loosen the force-bearing rod 4, and drive the car to carry the battery 1 to the side of the car that needs to be charged. Hold the force-bearing rod 4 again to pick up the device and place it at the designated position. The universal ball rod 6 again buffers and reduces shock to the battery 1 through the elastic bottom block 8 and the first spring 7. Then start the servo motor 92 and drive the positioning wheels 91 on the right side of the left and right sides through the synchronous belt assembly. The positioning wheels 91 on the right side of the left and right sides rotate forward through the reversing The gear 93 drives the remaining two positioning wheels 91 to rotate. The rotation of each group of two positioning wheels 91 drives the connecting wire 5 to move backward to release the wire. Then the operator pulls the head end of the connecting wire 5 to disengage from the battery 1, and connects the head end of the connecting wire 5 to the battery that needs to be jumpered. The battery 1 also jumpers the battery of the car through the connecting wire 5. The servo motor 92 is turned off, and the positioning wheel 91 stops driving the connecting wire 5 to move backward. After the jumper of the car battery is completed, the connecting wire 5 is removed from the car battery and clamped back on the battery 1. The connecting wire 5 is released, and then the servo motor 92 is started to reverse, so that the positioning wheel 91 reverses and drives the connecting wire 5 to move forward and reset to the inside of the support plate 3. The servo motor 92 is turned off, and the force-bearing rod 4 is held again so that the device is placed on the car for carrying. The universal ball rod 6 continues to buffer and damp the battery 1 through the first spring 7 and the elastic bottom block 8, which can prevent the battery 1 from being damaged by vibration, thereby increasing the service life of the battery 1. Example 2
[0034] On the basis of embodiment 1, a storage mechanism 10 is also included. The storage mechanism 10 includes a toothed belt assembly 101, a coaxial gear assembly 102, a rack 103, a limit rod 104, a magnetic conduit 105, a rotating shaft 106 and a sliding rod 107. Figure 5-Figure 7As shown, three groups of magnetic conduits 105 are fixedly connected at even intervals on the left and right sides of the support plate 3, and the number of each group of magnetic conduits 105 is two, and each group of two magnetic conduits 105 is staggered. A slide bar 107 is slidably connected to the inner side of each magnetic conduit 105. The material of the slide bar 107 is iron. The end of each slide bar 107 away from the magnetic conduit 105 is fixedly connected to a limit rod 104, and the limit rod 104 is in contact with the connection wire 5. The limit rod 104 can be bent and stored. A rack 103 is installed on the upper front side of each limit rod 104 by welding. Coaxial gear assemblies 102 are rotatably connected to the left and right sides of the support plate 3 at even intervals. The coaxial gear Component 102 is composed of a large gear and a small gear, and the small gear is located below the large gear. The three coaxial gear assemblies 102 are respectively located between the corresponding two magnetic tubes 105. The large gear of the coaxial gear assembly 102 is meshed with the rack 103. A rotating shaft 106 is symmetrically rotated on the left and right sides of the inner front side of the support plate 3. The upper parts of the rotating shafts 106 on the left and right sides are respectively connected to the upper parts of the shafts of the left and right positioning wheels 91 on the left and right sides with toothed belt assemblies 101. The toothed belt assembly 101 corresponds to the small gear of the coaxial gear assembly 102. When the toothed belt assembly 101 moves and meshes with the coaxial gear assembly 102, the toothed belt assembly 101 can drive the coaxial gear assembly 102 to rotate.
[0035] The cleaning mechanism 11 includes a cleaning frame 111, a guide rod 112, a second spring 113, a positioning rod 114 and a column-belted rotating seat 115. Figure 5 , Figure 8 and Fig. 9 As shown, guide rods 112 are symmetrically fixed to the left and right sides of the rear side surface of the support plate 3, and a brush holder 111 is slidably mounted between the two guide rods 112 on each side. The inner sides of the left and right brush holders 111 are respectively in contact with the left and right connecting wires 5. When the brush holder 111 moves, the brush holder 111 can remove impurities attached to the connecting wires 5. Second springs 113 are connected between the inner sides of the left and right brush holders 111 and the inner sides of the left and right guide rods 112 respectively. Positioning rods 114 are installed on the outer bottoms of the left and right brush holders 111 by welding. The bottom ends of the shafts of the outermost positioning wheels 91 on the left and right sides are fixedly connected to a column rotating seat 115. The front and rear ends of the column rotating seat 115 are fixedly connected to columns. The columns of the column rotating seat 115 are in contact with the positioning rod 114. When the column rotating seat 115 rotates, the column rotating seat 115 can drive the positioning rod 114 to move inward.
[0036] When it is necessary to jump-start the servo motor 92, the servo motor 92 is started to rotate forward, so that the positioning wheel 91 rotates, and the positioning wheels 91 on the left side of the left and right sides rotate to drive the toothed belt assembly 101 to rotate through the rotating shaft 106. When the toothed belt assembly 101 rotates and engages with the coaxial gear assembly 102, the rotation of the toothed belt assembly 101 drives the coaxial gear assembly 102 to rotate, and the rotation of the coaxial gear assembly 102 drives the rack 103 to move inward, and the inward movement of the rack 103 drives the limit rod 104 to move inward, and the inward movement of the limit rod 104 drives the slide bar 107 to move inward, and the slide bar 107 slides in the magnetic conduit 105, and the limit rod 104 moves inward without limiting the connection wire 5, and then the connection wire 5 moves backward and is driven to move backward. When the connection wire 5 is connected to the battery of the car, the servo motor 92 is turned off, the positioning wheel 91 stops driving the connection wire 5 to move backward, and the positioning wheels 91 on the left side of the left and right sides stop driving the toothed belt assembly 101 to rotate through the rotating shaft 106. The limit rod 104 also stops moving inward, and the magnetic conduit 105 attracts the sliding rod 107, which also limits the sliding rod 107. The sliding rod 107 limits the limit rod 104, and the battery of the car can be started to be charged. When the battery of the car is charged, the servo motor 92 is started to reverse, so that the positioning wheel 91 rotates in the opposite direction to drive the connecting wire 5 to move forward to the inside of the support plate 3. At the same time, the positioning wheels 91 on the left and right sides rotate through the rotating shaft 106 to drive the toothed belt assembly 101 to rotate in the opposite direction and reset. The toothed belt assembly 101 rotates in the opposite direction and resets to drive the coaxial gear assembly 102 to rotate in the opposite direction and reset. The coaxial gear assembly 102 rotates in the opposite direction and resets to drive the rack 103 to move outward and reset. The rack 103 moves outward and resets to drive the limit rod 104 to move outward and reset. The limit rod 104 moves outward and resets to bend the retracted connecting wire 5 to limit the position, and also arranges the connecting wire 5. At the same time, the limit rod 104 also drives the sliding rod 107 to move outward and reset. In this way, the connection wires 5 can be prevented from being scattered inside the support plate 3 and tangled, which would affect the use, thereby ensuring that the connection wires 5 can be neatly stored for subsequent use.
[0037] After the battery of the car is charged, the connecting wire 5 is removed from the battery of the car, and then the servo motor 92 is started. The rotation of the positioning wheels 91 on the left and right sides also drives the belt column rotating seat 115 to rotate. When the belt column rotating seat 115 rotates and contacts the positioning rod 114, the belt column rotating seat 115 drives the positioning rod 114 to move inward, and the positioning rod 114 moves inward to drive the cleaning brush frame 111 to move inward, and the second spring 113 is compressed. When the belt column rotating seat 115 continues to rotate and disengages from the positioning rod 114 When the second spring 113 is activated, the brush cleaning frame 111 moves outward to reset and drives the positioning rod 114 to move outward to reset. This is repeated. The brush cleaning frame 111 continuously moves inward and outward to remove impurities attached to the connecting wire 5. After the impurities are removed, the connecting wire 5 moves forward to the inside of the support plate 3 for storage. When the connecting wire 5 is wound up, the servo motor 92 is turned off, and the positioning wheels 91 on the left and right sides stop driving the column rotating seat 115 to rotate, and the positioning rod 114 stops driving the brush cleaning frame 111 to move inward and outward. In this way, a large amount of impurities attached to the connecting wire 5 can be prevented from being corroded and causing leakage, thereby ensuring the safe use of the connecting wire 5. Example 3
[0038] On the basis of the embodiment 1 and the embodiment 2, a protective cover 12 and a mounting seat 13 are also included. Fig.10 As shown, a mounting seat 13 is symmetrically fixed to the lower part of the rear side of the battery 1, and a protective cover 12 is rotatably connected between the inner ends of the left and right mounting seats 13. The protective cover 12 covers the tail ends of the two connecting wires 5, and the protective cover 12 can protect the connecting wires 5.
[0039] Also included is a crash pad 14, see Fig.10 As shown, anti-collision pads 14 are fixedly connected to the left and right side surfaces of the left and right limit frames 2 . When the battery 1 contacts the anti-collision pads 14 , the anti-collision pads 14 can protect the battery 1 .
[0040] When the connecting wire 5 needs to be connected to the battery of the car, the protective cover 12 is first pulled upward to swing away from covering the tail end of the connecting wire 5, and then the tail end of the connecting wire 5 is pulled to connect to the battery of the car. When the connecting wire 5 is reset, the protective cover 12 is pulled downward to swing back to cover the tail end of the connecting wire 5, and the protective cover 12 protects the tail end of the connecting wire 5. In this way, foreign debris can be prevented from damaging the tail end of the connecting wire 5, thereby ensuring the safety of the placement of the connecting wire 5.
[0041] When the battery 1 is buffered and shock-absorbed, the anti-collision pad 14 contacts the battery 1, and the anti-collision pad 14 protects the battery 1. In this way, the battery 1 can be prevented from being damaged by violently contacting the limiting frame 2, thereby ensuring the safety of the battery 1.
[0042] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
