[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] like Figure 1-6 As shown, a universal automobile inverter mounting device comprises: a mounting plate 2 with a first annular flange 1 protruding upward from the edge, a mounting mechanism mounted on the upper surface of the mounting plate 2 for fixing the inverter in the first annular flange 1, three mounting arms 4 arranged at intervals along the circumferential direction of the mounting plate 2 and mounted on the bottom of the mounting plate 2 through hinge shafts 3 whose axes are parallel to the axis of the mounting plate 2, a rotating shaft 5 coaxially mounted on the bottom of the mounting plate 2 through a first bearing, and a rotating plate 6 coaxially fixed on the rotating shaft 5, the middle part of each mounting arm 4 is hinged with a connecting rod 7 hinged with the rotating plate 6, and the bottom of the mounting plate 2 is equipped with an elastic member 8 for pushing the rotating plate 6 to rotate so as to drive the ends of the three mounting arms 4 away from the hinge shaft 3 to rotate away from the axis of the mounting plate 2.

[0029] Put the bottom end of the inverter into the inner side of the first annular flange 1, and make the bottom of the inverter fit the upper surface of the mounting plate 2, and then fix the inverter on the mounting plate 2 through the mounting mechanism; under the action of the elastic member 8, the ends of the three mounting arms 4 away from the hinge shaft 3 will disperse, and the installer will gather the three mounting arms 4 by hand, place the mounting plate 2 inside the cup holder, and then release the mounting arms 4, the elastic member 8 will push the turntable 6 to rotate, and the turntable 6 will push the mounting arms 4 to rotate around the hinge shaft 3 through the connecting rod 7, and the ends of the mounting arms 4 away from the hinge shaft 3 will move away from the axis of the mounting plate 2, and the three mounting arms 4 will disperse and hit the inner wall of the cup holder. Even if the car is bumpy during driving, the inverter will not shake relative to the cup holder to produce abnormal noise, and the fixed inverter will not tilt, that is, the connection socket on the top of the inverter is always facing upward, which is convenient for inserting the connecting line for use, and also prevents the connection from loosening due to the shaking of the inverter after the connecting line is inserted.

[0030] Because the cup holder generally has two connected cup placement grooves, the installer can use the space of the other cup placement groove to make the three mounting arms 4 in a gathered state before moving to the bottom of the cup placement groove. It only needs to push one of the mounting arms 4 to rotate close to the axis of the mounting plate 2, and the connecting rod 7 connected thereto can drive the turntable 6 to rotate, thereby driving the other two mounting arms 4 to rotate close to the axis of the mounting plate 2, so that one of the mounting arms 4 can be pressed and held by the space of the other cup placement groove.

[0031] There are three mounting arms 4 because the shapes of cup holder grooves of different car models are different, and the three contact points of the three mounting arms 4 can contact the inside of cup holder grooves of different shapes, which is highly practical.

[0032] A coaxial second annular flange 9 is protruded from the bottom of the mounting plate 2 . The second annular flange 9 is located on the inner side of the three mounting arms 4 . A limiting groove 10 is recessed on the lower surface of the second annular flange 9 for the corresponding connecting rod 7 to pass through.

[0033] The second annular flange 9 can limit the minimum distance between the end of the mounting arm 4 away from the hinge shaft 3 and the axis of the mounting plate 2, while the function of the limiting groove 10 is to indirectly limit the maximum distance between the end of the mounting arm 4 away from the hinge shaft 3 and the axis of the mounting plate 2 by limiting the movement of the connecting rod 7.

[0034] The elastic member 8 is a V-shaped metal spring sheet, and two ends of the metal spring sheet are respectively assembled on the rotating disk 6 and the mounting disk 2.

[0035] The mounting arm 4 is an arc-shaped arm, and the arc-shaped arm can fit the outer wall of the second annular flange 9 .

[0036] Because the arc-shaped arm fits the outer side of the second annular flange 9, the length of the arc-shaped arm can be increased, that is, the distance between the two ends of the mounting arm 4 is increased, thereby increasing the maximum distance between the end of the mounting arm 4 away from the hinge shaft 3 and the axis of the mounting plate 2, thereby improving applicability.

[0037] The upper surface of the mounting plate 2 is sunken with a strip groove 11 in the same radial direction, and the end of the strip groove 11 away from the axis of the mounting plate 2 is an open end;

[0038] The mounting mechanism includes a threaded rod 12 which is arranged in the strip groove 11 in the same length direction and whose end is mounted on the side wall of the strip groove 11 through a second bearing, a slider 13 which is threadedly sleeved on the threaded rod 12 and slidably mounted in the strip groove 11, a clamp 14 which is fixedly mounted on the slider 13 and in sliding contact with the upper surface of the mounting plate 2, and a mounting seat 15 which is fixedly mounted on the mounting plate 2 and covers the open end of the strip groove 11, the end of the threaded rod 12 away from the second bearing is axially connected to the mounting seat 15 and passes through the mounting seat 15, and the end of the threaded rod 12 away from the axis of the mounting plate 2 is fixedly mounted with a screw cap 16.

[0039] Rotating the screw cap 16 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the slider 13 to slide in the strip groove 11. When the slider 13 slides close to the axis of the mounting plate 2, the slider 13 of the clamp 14 is driven to contact the outer wall of the inverter. The clamp 14 and the inner wall of the first annular flange 1 can cooperate to tightly clamp inverters of different shapes.

[0040] Because the slider 13 can drive the clamp 14 to adjust the position, it can clamp inverters of different specifications and shapes.

[0041] A guide groove having the same length direction is recessed on at least one side wall of the strip-shaped groove 11 , and a convex block portion slidably inserted into the guide groove is protruded on the slider 13 .

[0042] The end of the mounting arm 4 away from the hinge shaft 3 is sleeved with a rubber sleeve 17 , and the rubber sleeve 17 can reduce damage to the inner wall of the cup holder.

[0043] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0045] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
