Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, specifically to a portable power supply structure. Background Technology

[0002] With the development of the outdoor camping economy, the demand for outdoor electricity has increased accordingly. Therefore, portable power banks have gradually become essential equipment for outdoor camping enthusiasts. Users typically use outdoor power banks in outdoor environments to power commonly used outdoor devices such as mobile devices, cooking appliances, projectors, outdoor refrigerators, and drones. Because outdoor power banks are relatively heavy and bulky, and the temporary outdoor work surfaces are limited in area and stability, and are the primary surface used by users outdoors, users generally place the outdoor power bank on the ground to avoid it taking up too much workspace, interfering with operation, or posing a risk of it falling off. However, outdoor ground is often not clean and may have dew at certain times. Therefore, when outdoor power banks are placed on the ground, the power cords of various devices may partially dangle on the ground or come into contact with weeds or other vegetation after being connected to the power bank. Over time, this can cause the cords to become dirty, and if there is dew on the ground, it may run down the cords to the power bank's socket, posing a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide a portable power supply structure that solves the problem of the power cord hanging below the power socket. The cord is raised above the socket by the cord groove on the handle, so that the cord is kept away from the ground where the power supply is placed and the crops on the ground, thereby avoiding the risk of the cord getting dirty and water entering the socket.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a portable power supply structure, including a power supply body and a handle, wherein the power supply body includes a power socket for connecting a power cord, the handle is disposed on the power supply body, the handle includes a hand-holding part and connecting parts connected to the left and right sides of the hand-holding part, the handle is provided with a wire groove, the wire groove is higher than the power socket, and is used to hold the power cord so that the power cord is raised above the power socket.

[0005] In one embodiment, the groove includes at least a first groove and a second groove, wherein the maximum width of the first groove is greater than the maximum width of the second groove.

[0006] In one embodiment, the grooves are arranged on the handheld part and / or the connecting part.

[0007] In one embodiment, the groove extends through the handle from front to back, and the direction of the groove's penetration forms an acute angle, a right angle, or an obtuse angle with the length direction of the handle and the connecting part.

[0008] In one embodiment, the groove is provided on the handheld part, and the through direction of the groove is consistent with the length direction of the handheld part.

[0009] In one embodiment, the groove is disposed on the connecting portion, and the through direction of the groove is consistent with the length direction of the connecting portion.

[0010] In one embodiment, the groove is disposed on the handheld part and the connecting part, and the groove extends continuously along the connecting part and the handheld part in sequence.

[0011] In one embodiment, the handle is provided with an inlet and an outlet, the inlet being connected to one end of the cable groove and the outlet being connected to the other end of the cable groove.

[0012] In one embodiment, the wire groove includes a first wire groove and a second wire groove. The wire groove is provided with a first rib, a second rib, and a third rib. The first rib, the second rib, and the third rib all extend along the through direction of the wire groove. The first rib and the second rib are respectively provided on the two side walls of the wire groove, and the third rib is provided on the bottom wall of the wire groove, so that the first wire groove is formed between the first rib and the second rib, and the second wire groove is formed between the first rib and the third rib and between the second rib and the third rib.

[0032] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0033] Please refer to Figure 1 This is a schematic diagram of the overall structure of the portable power supply structure shown in the first embodiment of this application. Figure 1 As shown, the portable power supply structure in this first embodiment includes a power supply body 100 and a handle 200. The power supply body 100 includes a power socket 110 for connecting a power cord 400. The handle 200 is disposed on the power supply body 100 and includes a hand-holding portion 210 and connecting portions 220 connected to the left and right sides of the hand-holding portion 210. The handle 200 is provided with a wire groove 300, which is higher than the power socket 110 and is used to hold the power cord 400 so that the power cord 400 is raised above the power socket 110.

[0034] In this first embodiment, the handle 200 is connected to the power supply body 100 via the connecting portion 220. In actual use, the user holds the handle portion 210 of the handle 200 to lift the power supply body 100. Therefore, at least when the power supply structure is in a lifted state, the handle 200 is at least partially higher than the power supply body 100 or entirely located on the upper side of the power supply body 100. When the power supply structure is in a placed state, if the overall position of the power supply structure has not changed compared to the lifted state, then the handle 200 is lifted. Handle 200 is at least partially higher than power supply body 100 or is located entirely on the upper side of power supply body 100; while plug port 110 is located on power supply body 100. In this first embodiment, plug port 110 is located on the four sides of power supply body 100 for connecting power cord 400. Thus, handle 200 is at least partially higher than plug port 110, so that wire groove 300 provided on handle 200 can be provided on the part of handle 200 that is higher than plug port 110, making wire groove 300 higher than plug port 110.

[0035] Of course, in some embodiments, the power outlet 110 can also be located on the top surface of the power supply body 100. In this case, it is sufficient that the handle 200 is at least partially higher than the power outlet 110 to allow the cable tray 300 to be installed. In other embodiments, when the power supply structure is in the placed state, its overall position has been flipped relative to the lifted state. For example, the handle 200 is located on the four sides of the power supply body 100 in the placed state. In this case, the power outlet 110 also needs to be located on the four sides of the power supply body 100, and in terms of their relative positions, the handle 200 is at least partially higher than the power outlet 110.

[0036] In actual use, the user connects the device’s power cord 400 to the power socket 110. It should be noted that the power cord 400 includes a connector 420 and a cord body 410. After the power cord 400 is connected to the power socket 110 through the connector 420, the connector 420 is fixed to the power socket 110, while the cord body 410 hangs down naturally or is pulled due to its flexibility, and its position is uncertain. In this first embodiment, when the power supply structure is in its placement state, the cable tray 300 is higher than the power outlet 110. After the user connects the power cord 400 to the power outlet 110 through the connector 420, the user can pull the cord 410 upwards to the handle 200 and insert the cord 410 into the cable tray 300. In this way, the handle 200 positions the cord 410 on the upper part of the power supply structure through the cable tray 300, preventing the cord 410 from naturally falling to the ground where the power supply structure is placed. This prevents the cord 410 from directly getting dirty from the ground, saving the user the trouble of cleaning the cord 410. It also prevents the cord 410 from coming into contact with dew on weeds or other crops on the ground during certain periods, thus preventing dew from flowing along the cord 410 to the power outlet 110 and causing a safety risk. In actual outdoor camping activities, many devices that require power supply, such as mobile terminals, cooking utensils, and projectors, are not outdoor-specific devices but rather everyday household appliances that users temporarily use outdoors. Therefore, ensuring the cleanliness of the power cords outdoors not only eliminates the need for users to clean the power cords after outdoor activities but also alleviates their psychological concerns about the cleanliness of the power cords during outdoor use. This allows users to use outdoor power sources with greater confidence and confidence, thereby promoting the further development of the outdoor camping economy.

[0037] It should be noted that the wire trough 300 in the embodiments of this specification is a through structure from one end to the other, and its circumferential direction is a semi-enclosed structure, that is, it has an opening for inserting the wire body 410 of the wire 400.

[0038] Please refer to Figure 2 This is a schematic diagram of the wire groove 300 shown in the second embodiment of this application. Figure 2As shown, the cable tray 300 of this second embodiment includes at least a first cable tray 310 and a second cable tray 320. The maximum width of the first cable tray 310 is greater than the maximum width of the second cable tray 320, so that the cable tray 300 can meet the connection requirements of at least two specifications of plug cables 400, that is, it can meet the connection requirements of plug cables 400 of different devices. When the power supply structure supplies power to multiple devices, the wires 410 of the plug cables 400 of these devices can all be raised and positioned by the cable tray 300, thereby avoiding dirt and water. For example, the plug cables 400 of mobile terminals (such as mobile phones, tablets, etc.), cooking appliances (such as rice cookers, air fryers, etc.), and tea and beverage appliances (such as coffee machines, kettles, etc.) have different thicknesses and require cable trays 300 of different widths to meet the connection requirements.

[0039] Please refer to Figure 3 This is a schematic diagram of the wire groove 300 shown in the third embodiment of this application. Figure 3 As shown, in this third embodiment, the cable trays 300 are arranged on the handle portion 210 and / or the connecting portion 220 of the handle 200. Specifically, in one embodiment, only all or part of the handle portion 210 is higher than the power outlet 110, so the cable trays 300 are only provided on the portion of the handle portion 210 that is higher than the power outlet 110; in another embodiment, the entire handle portion 210 is higher than the power outlet 110, and all or part of the connecting portion 220 is higher than the power outlet 110, so the cable trays 300 can be provided simultaneously on the portion of the connecting portion 220 that is higher than the power outlet 110 and on the handle portion 210, or the cable trays 300 can be provided only on the handle portion 210 or the connecting portion 220. This allows for the provision of as many cable trays 300 as possible to meet the needs of simultaneously powering multiple devices. Furthermore, in some embodiments, the wire 410 of a plug wire 400 is held in place by a wire groove 300, while in other embodiments, the wire 410 of a plug wire 400 can be held in place by two or more wire grooves 300. Specifically, the wire 410 passes through these wire grooves 300 in sequence, which also serves to organize the wires and improve the messy state of the wires 410.

[0040] Please refer to Figure 4 This is a schematic diagram of the wire groove 300 shown in the fourth embodiment of this application. Figure 4As shown, in this fourth embodiment, the wire groove 300 extends through the handle 200 from front to back, and the through direction of the wire groove 300 forms an acute angle, a right angle, or an obtuse angle with the length direction of the handle portion 210 and the connecting portion 220. In this fourth embodiment, the handle portion 210 is connected to the left and right sides by the connecting portion 220, which is connected to the power supply body 100 approximately downwards. Therefore, if the left-right direction is taken as the X-axis and the up-down direction as the Y-axis, the handle 200 extends in the plane of the X-axis and Y-axis to generate length, and the handle 200 generates width in the front-back direction. The wire groove 300 extends through the handle 200 from front to back, that is, the wire groove 300 extends through the width direction of the handle 200. In this way, multiple wire grooves 300 can be arranged at intervals along the length direction of the handle 200 without interfering with each other. The groove 300 passes through the handle 200 from front to back, meaning that the direction of the groove 300 does not follow the length of the handle 200. Specifically, the direction of the groove 300 forms an acute angle, a right angle, or an obtuse angle with the length of the handle 210 and the connecting part 220.

[0041] Please refer to Figure 5 This is a schematic diagram of the wire groove 300 shown in the fifth embodiment of this application. Figure 5 As shown, in this fifth embodiment, the wire groove 300 is provided on the handheld part 210, and the through direction of the wire groove 300 is consistent with the length direction of the handheld part 210. Thus, the through length of the wire groove 300 is selected within the length range of the handheld part 210. Compared with the fourth embodiment, the length of the wire groove 300 used to hold the wire body 410 can be increased, so that the wire groove 300 can position more wire bodies 410 above the plug port 110, further improving the lifting effect of the wire body 410 and improving the locking firmness. Moreover, the wire body 410 runs along the wire groove 300, which also plays a certain role in wire management and improves the aesthetics.

[0042] Please refer to Figure 6 This is a schematic diagram of the wire groove 300 shown in the sixth embodiment of this application. Figure 6 As shown, in this sixth embodiment, the wire groove 300 is provided on the connecting part 220, and the through direction of the wire groove 300 is consistent with the length direction of the connecting part 220. Thus, the through length of the wire groove 300 is selected within the length range of the connecting part 220. Compared with the fourth embodiment, the length of the wire groove 300 used to hold the wire body 410 can be increased, so that the wire groove 300 can position more wire bodies 410 above the plug-in port 110, further improving the lifting effect of the wire body 410 and improving the locking firmness. Moreover, the wire body 410 runs along the wire groove 300, which also plays a certain role in wire management and improves the aesthetics.

[0043] Please refer to Figure 7 This is a schematic diagram of the wire groove 300 shown in the seventh embodiment of this application. Figure 7As shown, in this seventh embodiment, the wire groove 300 is provided on the handle portion 210 and the connecting portion 220, and the wire groove 300 continuously runs through the connecting portion 220 and the handle portion 210. Thus, the length of the wire groove 300 is selected within the entire length range of the handle 200. Compared to the fifth and sixth embodiments, the length of the wire groove 300 used to hold the wire body 410 can be further increased, allowing the wire groove 300 to position more wire bodies 410 above the plug-in port 110, further improving the lifting effect on the wire bodies 410 and enhancing the locking firmness. Moreover, the wire body 410 runs along the longer wire groove 300, resulting in better wire management. It should be noted that in this seventh embodiment, regardless of the path by which the handle 210 and the connecting part 220 extend to form their length, the wire groove 300 is connected according to the shape of the handle 210 and the connecting part 220 in the length direction. Similarly, if the handle 210 and the connecting part 220 are connected by a corner, the wire groove 300 is also connected along the path of this corner.

[0044] It should be noted that, since the wire groove 300 has a semi-enclosed structure in the circumferential direction, that is, it has an opening in the circumferential direction for the wire body 410 to be inserted, in the fifth, sixth and seventh embodiments of this application, the wire groove 300 is provided on the outer periphery of the handle 200, wherein preferably the wire groove 300 is provided on the front or rear side of the handle 200 for easy operation.

[0045] In the fifth, sixth, and seventh embodiments, the wire groove 300 is provided on the handle portion 210 and / or the connecting portion 220 of the handle 200. The wire groove 300 itself is a concave structure. Therefore, when the wire 410 is inserted into the wire groove 300, the part inserted into the wire groove 300 is adapted to the wire groove 300 and is embedded in it. However, the two ends of the part of the wire 410 inserted into the wire groove 300 are in a state of connecting outward from the wire groove 300. This causes the wire 410 located at both ends of the wire groove 300 to protrude outward from the groove opening side of the wire groove 300. On the one hand, once it is pulled by external force, it is easy to drive the wire 410 that is already in the wire groove 300 to fall out of the wire groove 300. On the other hand, it is not aesthetically pleasing.

[0046] Therefore, please refer to Figure 8 This is a schematic diagram showing the connection between the cable tray 300 and the inlet 510 and the outlet 520. (See diagram below.) Figure 8As shown, the handle 200 has an inlet 510 and an outlet 520. The inlet 510 connects to one end of the cable groove 300, and the outlet 520 connects to the other end of the cable groove 300. Thus, after the cable 410 is partially inserted into the cable groove 300, both ends of the cable 410 located in the cable groove 300 extend outwards from the inlet 510 and the outlet 520, respectively. This design prevents the ends of the cable 410 inserted into the cable groove 300 from protruding from the groove opening, improving aesthetics. Furthermore, the inlet 510 and outlet 520 also provide a locking effect on the ends of the cable 410 inserted into the cable groove 300, further enhancing the secure connection between the handle 200 and the cable 410. This prevents the cable 410 from easily detaching from the cable groove 300 when the portion of the cable 410 outside the cable groove 300 is pulled, improving the user experience.

[0047] In the fifth, sixth and seventh embodiments, the wire groove 300 extends along the length of the handle 200. However, the width of the handle 200 is relatively narrow compared to its length, so arranging wire grooves 300 of different widths is somewhat difficult.

[0048] Therefore, please refer to Figure 9 This is a structural schematic diagram of the first groove 310 and the second groove 320. (See attached diagram.) Figure 9As shown, the wire groove 300 includes a first wire groove 310 and a second wire groove 320. The wire groove 300 is provided with a first rib 610, a second rib 620 and a third rib 630. The first rib 610, the second rib 620 and the third rib 630 all extend along the through direction of the wire groove 300. The first rib 610 and the second rib 620 are respectively provided on the two side walls of the wire groove 300, and the third rib 630 is provided on the bottom wall of the wire groove 300, so that the first rib 610 and the second rib 620 form the first wire groove 310, and the first rib 610 and the third rib 630 and the second rib 620 and the third rib 630 form the second wire groove 320. The maximum width of the first wire groove 310 is greater than the maximum width of the second wire groove 320. When a thinner power cord 400 needs to be connected, a portion of the power cord 400's wire 410 is connected to the second wire groove 320. Specifically, the first rib 610 and the third rib 630, or the second rib 620 and the third rib 630, act on the wire 410. When a thicker power cord 400 needs to be connected, a portion of the power cord 400's wire 410 is connected to the first wire groove 310. Specifically, the first rib 610 and the second rib 620 act on the wire 410. When both a thicker and a thinner power cord 400 need to be connected simultaneously, a portion of the thinner power cord 400's wire 410 is first connected to the second wire groove 320, and then the thicker power cord 400 is connected to the first wire groove 310, thus achieving the connection of the device's power cord 400. Furthermore, the maximum width of the two second grooves 320 on the left and right sides can be set to be the same or different. This can be achieved by selecting the position of the third rib 630 during the manufacturing process.

[0049] Please refer to Figure 10 This is a schematic diagram showing the structure of the handle 200 located in the storage slot. For example... Figure 10 As shown, the handle 200 is rotatably connected to the power supply body 100. The upper side of the power supply body 100 is provided with a storage groove corresponding to the handle 200, so that the handle 200 can rotate into the storage groove. In conjunction with the eighth embodiment, the two ends of the wire 410 of the plug cable 400 located in the wire groove 300 are connected to the outside of the wire groove 300 through the inlet 510 and the outlet 520, so the two ends do not protrude from the groove opening side of the wire groove 300. In this case, when the handle 200 rotates into the storage groove, the wire 410 is also brought into the storage groove, and the handle 200 can roughly cover the storage groove, further improving the aesthetic effect. Furthermore, if the handle 200 is rotated into the storage slot with its front side facing the storage slot, then the wire groove 300 is located on the front side of the handle 200; otherwise, it is located on the rear side of the handle 200. In this way, when the handle 200 is rotated into the storage slot, the wire groove 300 and the wire 410 located in the wire groove 300 are both located between the handle 200 and the storage slot and are completely covered. This not only improves the aesthetics but also protects the wire 410 and further enhances the secure connection of the wire 410.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
