Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a mobile power supply. Background Art

[0002] Nowadays in cities, people can easily enjoy the convenience brought by urban electric energy. However, more and more people now favor outdoor sports and like to experience nature outdoors. But it is inconvenient to use electricity outdoors, and they have to constantly pay attention to the remaining power of mobile devices. With the progress of technology, the mobile power supply technology has developed rapidly. The mobile power supply itself can store electric energy. Existing mobile power supplies can be directly used by mobile phones, laptop computers, cameras, fans, etc. Common output methods include 220VAC, USB, DC, etc., which is equivalent to a miniature power station to meet general travel needs.

[0003] Although various interfaces are provided in existing mobile power supplies, the sockets of mobile power supplies and the plugs of conventional electrical appliances are all manufactured according to industry standards, and the plugs of electrical appliances can be directly plugged and matched with these interfaces. However, in some cases, a wiring method needs to be adopted to deal with emergencies. For example, in case of a vehicle breakdown, the vehicle needs to be started by means of wire connection, while existing mobile power supplies do not have interfaces directly connected to wires. Therefore, existing mobile power supplies cannot be directly connected to wires. But if the wire is directly inserted into the jack of the mobile power supply, there will be poor contact and it is very unsafe to use electricity. Summary of the Invention

[0004] In view of the defects in the prior art, to increase the wiring function of the mobile power supply and improve the safety factor of electricity use. The present invention provides a mobile power supply, including a housing and a power supply body installed in the housing, and the front side wall of the housing is provided with a 220VAC interface area, a USB interface area, and a DC interface area;

[0005] The front side wall is further provided with a wire insertion area, and the wire insertion area is provided with a positive electrode hole and a negative electrode hole; a wire biting assembly corresponding to the positive electrode hole and the negative electrode hole one by one is arranged inside the housing, and each wire biting assembly includes a fixing plate, a movable plate, an upper clamping plate, a lower clamping plate, and a longitudinal driving assembly;

[0006] The fixing plate is fixedly connected to the housing, the movable plate is slidably connected to the housing along the transverse direction, the upper clamping plate is slidably connected to the fixing plate along the longitudinal direction through the longitudinal driving assembly, the lower clamping plate is slidably connected to the movable plate along the longitudinal direction through another longitudinal driving assembly, and the lower side of the upper clamping plate is opposite to the upper side of the lower clamping plate, and the upper clamping plate and the lower clamping plate are driven by the longitudinal driving assembly to separate or close along the longitudinal direction.

[0007] The beneficial effects of the present invention are embodied in:

[0008] Like existing mobile power supplies, it is applicable to 220V plugs, USB plugs, and DC plugs, and supports multiple power supply methods. In addition, it can also be directly connected to a wire. The connection method is to insert the exposed copper wire of the wire into the positive hole or the negative hole, and then the longitudinal drive assembly drives the upper clamping plate and the lower clamping plate to close, thereby clamping the copper wire. It is applicable to a single thick copper wire and also applicable to multiple thin copper wires. Conversely, when the longitudinal drive assembly drives the upper clamping plate and the lower clamping plate to separate, the copper wire is loosened. The connection is fast and the operation is simple. At the same time, it also ensures good contact of the wire, greatly reducing the possibility of electric sparks caused by poor contact and improving the safety level of electricity use.

[0009] Preferably, between the upper clamping plate of each wire-biting assembly and the corresponding fixed plate, and between the lower clamping plate and the corresponding movable plate, they are all longitudinally slidably connected through a slide rail assembly. The longitudinal slide rail assembly limits the sliding of the upper clamping plate and the lower clamping plate, making the clamping of the copper wire by the upper clamping plate and the lower clamping plate more stable.

[0010] Preferably, the longitudinal drive assembly includes a longitudinal electric cylinder. Between the upper clamping plate of each wire-biting assembly and the corresponding fixed plate, and between the lower clamping plate of each wire-biting assembly and the corresponding movable plate, multiple longitudinal electric cylinders are connected.

[0011] Preferably, three longitudinal electric cylinders are provided between each upper clamping plate and the corresponding fixed plate, and the three longitudinal electric cylinders are respectively located on both sides and in the middle of the upper clamping plate.

[0012] Preferably, three longitudinal electric cylinders are provided between each lower clamping plate and the corresponding movable plate, and the three longitudinal electric cylinders are respectively located on both sides and in the middle of the lower clamping plate. The six longitudinal electric cylinders provide strong thrust, strengthening the clamping force of the upper clamping plate and the lower clamping plate.

[0013] Preferably, the telescopic rod of the longitudinal electric cylinder of each fixed plate faces downward and is fixedly connected to the upper edge of the upper clamping plate, and the telescopic rod of the longitudinal electric cylinder of each movable plate faces upward and is fixedly connected to the lower edge of the lower clamping plate.

[0014] Preferably, between the movable plate of each wire-biting assembly and the housing, they are all horizontally slidably connected through another slide rail assembly. Similarly, the horizontal slide rail assembly ensures the horizontal sliding of the movable plate.

[0015] Preferably, it includes a horizontal drive assembly; the horizontal drive assembly is connected between the two movable plates, and drives the two movable plates to reciprocate horizontally through the horizontal drive assembly.

[0016] Preferably, the horizontal drive assembly includes a left extending electric cylinder and a right extending electric cylinder. The telescopic shaft of the left extending electric cylinder is fixedly connected to the movable plate of the wire-biting assembly behind the positive hole, and the telescopic shaft of the right extending electric cylinder is fixedly connected to the movable plate of the wire-biting assembly behind the negative hole.

[0017] Preferably, a row of wavy teeth is provided on the lower edge of the upper clamping plate, and another row of wavy teeth adapted to the wavy teeth of the upper clamping plate is provided on the upper edge of the lower clamping plate. For a wire composed of multiple thin copper wires, in order to clamp it more firmly, the lateral driving assembly drives the movable plate and the lower clamping plate to reciprocate horizontally together, squeezing the multiple thin copper wires evenly and dispersing them into the grooves of the wavy teeth, and biting each thin copper wire as much as possible, so as to further strengthen the clamping force of the wire.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will describe in detail the embodiments of the technical solutions of the present invention with reference to the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0023] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

[0024] As Figure 1 shown, this embodiment provides a mobile power supply, including a housing 1 and a power supply body installed in the housing 1, and the front side wall of the housing 1 is provided with a wire plugging area 2, a 220VAC interface area 3, a USB interface area 4 and a DC interface area 5. The top wall of the housing 1 is provided with a handle 6. Among them, the 220VAC interface area 3, the USB interface area 4 and the DC interface area 5 are all provided with a plurality of corresponding interfaces. A 220V plug, a USB plug and a DC plug can be directly plugged into the corresponding interfaces to provide multiple power supply methods.

[0025] As Figure 2 shown, in this embodiment, the wire insertion area 2 is provided with a positive electrode hole 7 and a negative electrode hole 8. The exposed copper wires of the wire can be directly inserted into the positive electrode hole 7 and the negative electrode hole 8 and clamped. The specific clamping structure is as follows:

[0026] Inside the housing 1, there are wire biting assemblies corresponding to the positive electrode hole 7 and the negative electrode hole 8 one by one, and the structures of the two wire biting assemblies are exactly the same. Each wire biting assembly includes a fixing plate 9, a movable plate 10, an upper clamping plate 11, a lower clamping plate 12, and a longitudinal driving assembly. The fixing plate 9 is fixedly connected to the mounting plate 20 inside the housing 1. The movable plate 10 is slidably connected to the mounting plate 20 inside the housing 1 along the transverse direction, and the mounting plate 20 is provided with blind holes 21 corresponding to the positive electrode hole 7 and the negative electrode hole 8. The blind holes 21 are used to limit the insertion depth of the wire. The upper clamping plate 11 is slidably connected to the fixing plate 9 along the longitudinal direction through the longitudinal driving assembly, and the lower clamping plate 12 is slidably connected to the movable plate 10 along the longitudinal direction through another longitudinal driving assembly. Moreover, the lower edge of the upper clamping plate 11 faces the upper edge of the lower clamping plate 12, and the upper clamping plate 11 and the lower clamping plate 12 are driven by the longitudinal driving assembly to separate or close along the longitudinal direction. Further, between the upper clamping plate 11 and the corresponding fixing plate 9 of each wire biting assembly, and between the lower clamping plate 12 and the corresponding movable plate 10, they are slidably connected longitudinally through a slide rail assembly 17. The longitudinal slide rail assembly 17 limits the sliding of the upper clamping plate 11 and the lower clamping plate 12, and the upper clamping plate 11 and the lower clamping plate 12 clamp the copper wire more firmly.

[0027] In this embodiment, the longitudinal driving assembly includes a longitudinal electric cylinder 13. Between the upper clamping plate 11 and the corresponding fixing plate 9 of each wire biting assembly, and between the lower clamping plate 12 and the corresponding movable plate 10 of each wire biting assembly, a plurality of longitudinal electric cylinders 13 are connected. There are three longitudinal electric cylinders 13 between each upper clamping plate 11 and the corresponding fixing plate 9, and the three longitudinal electric cylinders 13 are respectively located at both sides and the middle of the upper clamping plate 11. There are three longitudinal electric cylinders 13 between each lower clamping plate 12 and the corresponding movable plate 10, and the three longitudinal electric cylinders 13 are respectively located at both sides and the middle of the lower clamping plate 12. The six longitudinal electric cylinders 13 provide strong thrust, strengthening the clamping force of the upper clamping plate 11 and the lower clamping plate 12. The telescopic rods of the longitudinal electric cylinders 13 of each fixing plate 9 face downward and are fixedly connected to the upper edge of the upper clamping plate 11, and the telescopic rods of the longitudinal electric cylinders 13 of each movable plate 10 face upward and are fixedly connected to the lower edge of the lower clamping plate 12. Moreover, a row of wave teeth 14 is provided on the lower edge of the upper clamping plate 11, and another row of wave teeth 14 adapted to the wave teeth 14 of the upper clamping plate 11 is provided on the upper edge of the lower clamping plate 12. The six longitudinal electric cylinders 13 drive the upper clamping plate 11 and the lower clamping plate 12 to approach and contact, and the two rows of wave teeth 14 bite to clamp the copper wire, which is applicable to a single thick copper wire and also applicable to multiple thin copper wires.

[0028] In order to enable the upper clamping plate 11 and the lower clamping plate 12 to better clamp multiple thin copper wires, a lateral driving assembly is further included in this embodiment; the lateral driving assembly is connected between the two movable plates 10, and drives the two movable plates 10 to reciprocate horizontally through the lateral driving assembly. Further, each movable plate 10 of the wire biting assembly is horizontally slidably connected to the housing 1 through another slide rail assembly 17. Similarly, the horizontal slide rail assembly 17 ensures the horizontal sliding of the movable plate 10. The lateral driving assembly includes a left extending electric cylinder 15 and a right extending electric cylinder 16. The telescopic shaft of the left extending electric cylinder 15 is fixedly connected to the movable plate 10 of the wire biting assembly behind the positive electrode hole 7, and the telescopic shaft of the right extending electric cylinder 16 is fixedly connected to the movable plate 10 of the wire biting assembly behind the negative electrode hole 8.

[0029] This embodiment further includes an electronic control board installed in the housing 1, as well as a button board 18 and a display screen 19 installed on the outer surface of the front side wall. The button board 18 is provided with a negative electrode hole 8 clamping button, a negative electrode hole 8 releasing button, a positive electrode hole 7 clamping button, a positive electrode hole 7 releasing button, a one-key clamping button and a one-key releasing button. The input end of the electronic control board is respectively electrically connected to the button board 18 and the power supply body, and the output end of the electronic control board is respectively electrically connected to all the longitudinal electric cylinders 13, the left extending electric cylinder 15 and the right extending electric cylinder 16.

[0030] The initial positions of the upper clamping plates 11 and the lower clamping plates 12 of the two wire biting assemblies are separated, and the method for clamping the wire is as follows:

[0031] S1: Insert the exposed copper wires of the wire into the negative electrode hole 8, and then press the negative electrode hole 8 clamping button;

[0032] S2: The control board makes the six longitudinal electric cylinders 13 behind the negative electrode hole 8 extend simultaneously, and at the same time the right extending electric cylinder 16 drives the movable plate 10 behind the negative electrode hole 8 to reciprocate horizontally, so as to evenly disperse and extrude multiple thin copper wires into the grooves of the wave teeth 14 until the wire is bitten between the upper clamping plate 11 and the lower clamping plate 12. The six longitudinal electric cylinders 13 and the right extending electric cylinder 16 both stop extending and maintain the current extended state, and the clamping of the wire in the negative electrode hole 8 is completed;

[0033] S3: Insert the exposed copper wires of the wire into the positive electrode hole 7, and then press the positive electrode hole 7 clamping button;

[0034] S4: The control board makes the six longitudinal electric cylinders 13 behind the positive electrode hole 7 extend simultaneously, and at the same time the left extending electric cylinder 15 drives the movable plate 10 behind the negative electrode hole 8 to reciprocate horizontally, so as to evenly disperse and extrude multiple thin copper wires into the grooves of the wave teeth 14 until the wire is bitten between the upper clamping plate 11 and the lower clamping plate 12. The six longitudinal electric cylinders 13 and the left extending electric cylinder 15 both stop extending and maintain the current extended state, and the clamping of the wire in the positive electrode hole 7 is completed.

[0035] Conversely, when the button is released after pressing the negative electrode hole 8 or the positive electrode hole 7, the electronic control board causes the corresponding six longitudinal electric cylinders 13 to retract simultaneously, releasing the wire. Additionally, two wires can be inserted into the negative electrode hole 8 and the positive electrode hole 7 respectively, and when the one-key clamping button is pressed, the two wire clamping components clamp onto the corresponding wires simultaneously. Similarly, when the one-key release button is pressed, the two wire clamping components release the wires simultaneously.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
