Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted inverters, and more specifically, to a portable vehicle-mounted inverter. Background Art

[0002] With the rapid development of the automobile industry and the increasing demand for travel convenience, portable car inverters, as a device that can convert the DC power of the car cigarette lighter interface into AC power that can be used by household appliances, are becoming more and more popular among car owners. This inverter can not only charge mobile devices such as mobile phones and laptops, but also provide power for small household appliances, thus greatly improving the convenience and comfort of travel.

[0003] However, in actual use, existing portable car inverters have a significant problem: the wires connected to them tend to become scattered after use. These scattered wires not only affect the cleanliness of the car, but also easily become tangled or knotted if not sorted out in time, causing great inconvenience to subsequent use. Car owners usually need to spend extra time and energy to manually sort out these wires, which not only reduces the user experience, but also increases the cost of use to a certain extent.

[0004] To solve this problem, some inverters with simple cable management functions have appeared on the market, but most of them are complex in design and ineffective, and often cannot effectively solve the fundamental problem of scattered and tangled wires. For example, some inverters are equipped with simple cable ties or cable clips, but these designs can usually only simply fix the wires and cannot achieve the function of automatic reeling and tidying.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a portable vehicle inverter. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a portable vehicle-mounted inverter.

[0007] To achieve the above object, the utility model provides the following technical solution: a portable vehicle-mounted inverter, comprising an inverter body and a wire arranged on the inverter body, and further comprising:

[0008] A winding box installed on the inverter body;

[0009] A winding mechanism is arranged in the winding box, the winding mechanism includes a winding post rotatably installed in the winding box, and the winding box is connected to the winding post through a torsion spring, a wire groove in a continuous spiral shape is opened on the surface of the winding post, the wire is wound on the winding post, and the wire fits in the wire groove, and the winding mechanism is used to retract and release the wire;

[0010] A limiting mechanism is arranged in the winding box, and the limiting mechanism includes a limiting tooth arranged on the winding pole, the limiting tooth is rotatably connected in the winding box, and the limiting tooth is abutted against a clamping rod, the clamping rod is rotatably connected in the winding box, and the end of the clamping rod away from the limiting tooth is connected to a button, one end of the button extends out of the winding box and is slidably connected to the winding box, and the other end of the button is connected to a support block through an elastic member, and the support block is installed in the winding box.

[0011] Preferably, a guide groove is provided on the surface of the winding box, the wire is wound on the winding pole and extends out of the winding box through the guide groove, the wire enters the winding box from the inverter body, and is wound on the winding pole, and extends out of the winding box from the guide groove, which is convenient for winding the wire.

[0012] Preferably, a brush for cleaning the wire is provided on the guide groove. When the winding rod reels the wire, the wire passes through the brush, and the brush can remove some impurities that may exist on the wire, thereby reducing the possibility of impurities entering the winding box.

[0013] Preferably, the diameter of the wire is larger than the distance between the winding post and the inner wall of the winding box, so that the wire can be stuck in the guide groove, avoiding the problem that part of the wire may be offset to the surface of the winding post during winding, causing uneven winding or even causing the winding post to get stuck.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a winding box is arranged on the inverter body, and the winding box can reel in the wire through a winding mechanism arranged inside. The wire can be pulled out of the winding box by pulling the wire, and at the same time, the winding column drives the torsion spring to rotate. The torsion spring accumulates elastic force. After use, the winding column is driven to rotate under the elastic force of the torsion spring to reel in the released wire, thereby realizing automatic reeling in of the used wire, reducing the tediousness of manual wire management, thereby solving the problems in the prior art of scattered wires affecting subsequent use and the tediousness of manual management, and improving user experience.

[0016] 2. In the utility model, the winding post can be limited by a limiting mechanism arranged on the winding post. When the wire is pulled, the limiting teeth rotate normally. After the pulling of the wire stops, the torsion spring will drive the winding post to rotate in the opposite direction. At this time, due to the interference between the clamping rod and the limiting teeth, the winding post cannot rotate, so as to avoid the wire being wound up during use and affecting normal work. When use is completed, the clamping rod can be pressed to leave the surface of the limiting teeth, so that the winding post rotates in the opposite direction under the elastic force of the torsion spring to wind up the wire.

[0017] 3. By controlling the diameter of the wire to be larger than the distance between the winding post and the inner wall of the winding box, the wire can be stuck in the guide groove, avoiding the problem that part of the wire may deviate to the surface of the winding post during winding, causing uneven winding or even causing the winding post to get stuck.

[0024] like Figure 1-4 As shown, the utility model provides a portable vehicle-mounted inverter, including an inverter body 1 and a wire 3 arranged on the inverter body 1, and also includes:

[0025] A winding box 4 mounted on the inverter body 1;

[0026] A winding mechanism 5 is arranged in the winding box 4, the winding mechanism 5 includes a winding post 501 rotatably mounted in the winding box 4, and the winding box 4 is connected to the winding post 501 through a torsion spring 503, a continuous spiral-shaped wire groove 502 is opened on the surface of the winding post 501, the wire 3 is wound on the winding post, and the wire 3 fits in the wire groove 502, and the winding mechanism 5 is used to retract and release the wire 3;

[0027] A limiting mechanism 6 is arranged in the winding box 4, and the limiting mechanism 6 includes a limiting tooth 601 arranged on the winding column 501, the limiting tooth 601 is rotatably connected in the winding box 4, and the limiting tooth 601 is abutted and connected with a clamping rod 602, the clamping rod 602 is rotatably connected in the winding box 4, and one end of the clamping rod 602 away from the limiting tooth 601 is connected with a button 605, one end of the button 605 extends out of the winding box 4 and is slidably connected to the winding box 4, and the other end of the button 605 is connected to a support block 603 through an elastic member 604, and the support block 603 is installed in the winding box 4;

[0028] It is worth noting that the limiting tooth 601 and the clamping rod 602 limit the counterclockwise rotation direction of the winding post 501. When the winding post 501 rotates clockwise, the limiting tooth 601 does not limit the winding post 501.

[0029] It should be noted that when the wire 3 is completely wound around the winding post, the torsion spring 503 is in an unstressed state;

[0030] The surface of the winding box 4 is provided with a guide groove 2, the wire 3 is wound on the winding post 501 and extends out of the winding box 4 through the guide groove 2, the wire 3 enters the winding box 4 from the inverter body 1, and is wound on the winding post, and extends out of the winding box 4 from the guide groove 2, so as to facilitate winding of the wire 3;

[0031] In summary, when the inverter is used, the wire 3 is pulled out from the winding box 4, and the winding column 501 rotates clockwise as the wire 3 is pulled out, thereby driving the torsion spring 503 to rotate, so that the torsion spring 503 accumulates elastic force;

[0032] After the wire 3 is pulled out to a suitable length, the wire 3 is released, and the torsion spring 503 drives the winding post 501 to rotate counterclockwise under the accumulated elastic force. However, due to the interference between the clamping rod 602 and the limiting tooth 601, the winding post 501 is stuck in the winding box 4, and the winding post 501 does not rotate at this time.

[0033] After the inverter is used, the button 605 is pressed, and the button 605 compresses the elastic member 604 and drives the clamping rod 602 to rotate. Figure 2-3 As shown, the clamping rod 602 is abutted against one end of the limiting tooth 601 and slides off the surface of the limiting tooth 601, so that the clamping rod 602 no longer limits the limiting tooth 601 and the winding rod 501, and the winding rod 501 rotates counterclockwise under the elastic force of the torsion spring 503, so that the released wire 3 is rewound on the winding rod 501, so as to realize automatic rewinding of the used wire 3, and reduce the tediousness of manual wire arrangement. After the automatic rewinding is completed, the button 605 is released, and the button 605 returns to its original position under the elastic force of the elastic member 604;

[0034] It is worth noting that the diameter of the wire 3 is larger than the distance between the winding post 501 and the inner wall of the winding box 4, so that the wire 3 can be stuck in the guide groove 2, avoiding the problem that part of the wire 3 may deviate to the surface of the winding post 501 during winding, causing uneven winding or even causing the winding post to get stuck;

[0035] Among them, a brush 7 for cleaning the wire 3 is arranged on the guide groove 2. When the winding rod 501 reels the wire 3, the wire 3 passes through the brush 7. The brush 7 can remove some impurities that may exist on the wire 3, thereby reducing the possibility of impurities entering the winding box 4.

[0036] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
