Example

[0034] Please see Figure 1-8This invention provides an outdoor portable power supply, including a housing 1 and an end cap 2. The housing 1 and the end cap 2 are hinged and fixed. An inverter module 3 and a battery module 4 are installed inside the housing 1. It also includes a photovoltaic charging module 5 and an audio system 6. The photovoltaic charging module 5 is composed of multiple photovoltaic panels 51 connected in series by connectors 52 and folded for storage. The photovoltaic charging module 5 is used to charge the battery module 4 outdoors by connecting to the inverter module 3. The audio system 6 is distributed and installed on the photovoltaic charging module 5 and connected to the inverter module 3. The connectors 52 are used to fix adjacent photovoltaic panels 51 and to fix the terminals of adjacent photovoltaic panels 51 to the photovoltaic charging module 5.

[0035] In the embodiments of this application, an inverter module 3 and a battery module 4 are assembled inside the housing 1. The inverter module 3 is connected to the battery module 4, and the inverter module 3 is also connected to the photovoltaic charging module 5 and the audio system 6. The external speaker of the audio system 6 is mounted on the photovoltaic charging module 5 and can be folded, stored, and unfolded with the photovoltaic charging module 5 for use.

[0036] An end cap 2 is installed on the back of the housing 1. The end cap 2 has a storage cavity 21 for holding the stored photovoltaic charging module 5.

[0037] In the embodiments of this application, the audio system 6 consists of a system controller, a power amplifier, and speakers. The system controller and the power amplifier are integrated and installed inside the housing 1 and connected to the battery module 4 through the inverter module 3. The speakers are distributed and installed on the photovoltaic panel 51 and connected in series with each other to the power amplifier.

[0038] In the embodiments of this application, the photovoltaic charging module 5 consists of a photovoltaic panel 51, connectors 52, and brackets 53. The photovoltaic panel 51 is mounted on the bracket 53, and connectors 52 are installed on both sides of each bracket 53. Adjacent brackets 53 are connected in series and fixed by connectors 52. The connectors 52 are fastened and disassembled by pressing and extending.

[0039] The bracket 53 has limiting holes 54 at both the top and bottom. The speaker will be installed in the limiting holes 54 to prevent contact and damage when the bracket 53 is folded.

[0040] It should be noted that the connector 52 is composed of a first mounting base 521, a second mounting base 522, and a locking component 524. Two second mounting bases 522 and a first mounting base 521 are respectively installed on the left and right sides of the bracket 53. The second mounting bases 522 and the first mounting bases 521 are symmetrical from left to right, and the two first mounting bases 521 and the two second mounting bases 522 are symmetrically arranged vertically.

[0041] A movable pin 523 is movably mounted on the first mounting base 521. The other end of the movable pin 523 is used to pass into the second mounting base 522. Each second mounting base 522 is equipped with a locking element 524, which can pass through the movable pin 523 to movably connect itself to the second mounting base 522.

[0042] It should be noted that the photovoltaic panel 51 is provided with a wiring port 511 and a wiring harness assembly 512. There are two sets of both the wiring port 511 and the wiring harness assembly 512, which are arranged in parallel and are used for connecting the speaker to the photovoltaic panel 51. After the port of the wiring harness assembly 512 is inserted into the wiring port 511, the series connection of adjacent photovoltaic panels 51 and the series connection between speakers are realized.

[0043] The port of the wire harness assembly 512 is provided with an ear seat 513 with an opening. Adjacent wire harness assemblies 512 can be magnetically attached or Velcro-attached in some applications. Two locking members 524 are respectively provided at the ends of the two second mounting seats 522, and each locking member 524 can be inserted into the ear seat 513 on that side.

[0044] In the embodiments of this application, the locking member 524 consists of a base 5241, an elastic rotating member 5242, and a sliding rod 5243. The base 5241 is fixed to the side of the bracket 53. The elastic rotating member 5242 and the sliding rod 5243 are both installed on the base 5241. The elastic rotating member 5242 protrudes into the base 5241. The bottom of the elastic rotating member 5242 passes through the sliding rod 5243 and engages with it circumferentially. Pressing the elastic rotating member 5242 will cause it to drive the sliding rod 5243 to rotate synchronously. The surface of the sliding rod 5243 is provided with a sliding groove 5244 of a closed loop. A protrusion that passes through the sliding groove 5244 is fixed in the base 5241. When the sliding rod 5243 rotates, it moves downward along the protrusion and passes through the base 5241.

[0045] The elastic rotating component 5242 includes a bushing 5245, a rotating seat 5246, a button 5247, a rotating shaft 5248, a first spring 5249, etc. The rotating seat 5246 is installed inside the bushing 5245. The first spring 5249 is installed at the bottom of the bushing 5245 to lift the rotating seat 5246. The button 5247 passes through the top of the bushing 5245 and is connected to the rotating seat 5246. The rotating shaft 5248 passes through the bottom of the bushing 5245 and is connected to the rotating seat 5246.

[0046] The bottom of the rotating shaft 5248 is inserted into the slide rod 5243 and engages with it circumferentially. The button 5247 protrudes from the surface of the base 5241. Pressing the button 5247 with external force can control the rotation of the rotating shaft 5248, which rotates 120° each time. Each time the rotating shaft 5248 rotates, the slide rod 5243 rotates synchronously. However, due to the protrusion, the slide rod 5243 will first extend outward and pass into the second mounting base 522 to fix the movable pin 523. When the button 5247 is pressed a second time, the rotating shaft 5248 will drive the slide rod 5243 to rotate 120° again. At this time, the slide rod 5243 will continue to extend outward and pass through the ear seat 513 to fix the wire harness assembly 512. When button 5247 is pressed for the third time, the rotating shaft 5248 drives the slide bar 5243 to rotate 120°, and the protrusion moves from the lowest end of the slide groove 5244 to the highest end. The highest end of the slide groove 5244 is vertically connected to the lowest end. A second spring is installed inside the base 5241 to support the slide bar 5243. When the slide bar 5243 moves, the second spring is stretched. When the protrusion moves from the lowest end of the slide groove 5244 to the highest end, the second spring will pull the slide bar 5243 back to the initial position of the slide groove 5244. At this time, the rotating shaft 5248 and the slide bar 5243 rotate one full circle and return to the initial position.

[0047] Each time button 5247 is pressed, the first spring 5249 will return it to its initial position.

[0048] It should be noted that the rotating seat 5246 and the bushing 5245 are circumferentially engaged. After the bushing 5245 is fixed on the base 5241, it can only move in the vertical direction. The rotating seat 5246 is composed of an upper sleeve, a lower sleeve, and a connecting rod. The upper sleeve and the lower sleeve are spaced apart and fixed by the connecting rod. The facing end faces of the upper sleeve and the lower sleeve have grooves forming a wave-like shape with three peaks and troughs. The peaks and troughs of the upper sleeve and the lower sleeve are staggered. The top side of the rotating shaft 5248 has a protrusion. After the top of the rotating shaft 5248 passes through the lower sleeve, the protrusion is located at the trough of one of the lower sleeves. The button 5247 is connected and fixed to the upper sleeve. Each time the rotating seat 5246 is pressed, the whole structure moves. The protrusion will move from the lower trough into the upper trough. After the external force is removed, the first spring 5249 rebounds, causing the protrusion to move into the adjacent lower trough. Therefore, each time button 5247 is pressed, the protrusion of the rotating shaft 5248 moves from one trough to another, causing the rotating shaft 5248 to rotate 120°. And every three presses of button 5247, the rotating shaft 5248 returns to its initial position.

[0049] In this invention, two second mounting bases 522 and locking members 524 are symmetrically arranged. By allowing two sliding rods 5243 to pass through the second mounting bases 522 from symmetrical positions, the connection of the two brackets 53 can be achieved. At the same time, the protruding length of the sliding rods 5243 can be controlled, so that the wiring harness assembly 512 can be fixed after the brackets 53 are connected, thus preventing the interface from becoming loose during the folding and unfolding of the photovoltaic charging module 5.

[0050] The connector 52 of the present invention protrudes outward and is operated by a button 5247 to control the connection and disassembly of the two brackets 53 and the fixing and disassembly of the wiring harness assembly 512. The fixing is performed sequentially, so that the replacement of the speaker and the replacement of the photovoltaic panel 51 are independent and unaffected.

[0051] In this application, the protruding button 5247 can be covered to prevent accidental touch.

[0052] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
