In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "up," "down," and the like are for illustrative purposes only and do not indicate or imply that the referenced device or element must be in a particular orientation, constructed or operated in a particular manner, and is not to be construed as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a first embodiment of the present invention provides a frame, which includes a first cross beam 1, a second cross beam 2, and a longitudinal beam 3, which are orthogonally connected to each other, wherein an assembly 4 is disposed at a connection position of the first cross beam 1, the second cross beam 2, and the longitudinal beam 3, the assembly 4 includes a first connecting sheet 41, a second connecting sheet 42, and a third connecting sheet 43, which are integrally formed, and the first connecting sheet 41, the second connecting sheet 42, and the third connecting sheet 43 are respectively and fixedly connected to the first cross beam 1, the second cross beam 2, and the longitudinal beam 3.

The invention has the advantages that only one assembly part 4 is needed to be adopted at the joint of the first cross beam 1, the second cross beam 2 and the longitudinal beam 3, the complexity of installation is reduced, and the first connecting sheet 41, the second connecting sheet 42 and the third connecting sheet 43 are integrally formed, so that the strength of the assembled frame is greatly improved.

Specifically, the second connecting piece 42 is an extending section of the side surface of the first connecting piece 41, and the third connecting piece 43 is an extending section of the first connecting piece 41 after being bent. In fig. 3, the third connecting piece 43 is an extension of the first connecting piece 41 that is bent upward.

Preferably, the end of the second connecting piece 42 is provided with a flange 421, and a reinforcing rib 44 is provided along the edges of the first connecting piece 41 and the third connecting piece 43.

It will be appreciated that the flanges 421 and ribs 44 enhance the lateral strength of the assembly 4 and prevent the assembly 4 from bending.

It should be noted that the assembly 4 is only one of the fixing methods, and in this embodiment, the assembly 4 is used for only one connection point, and the other connection points are welded. In other embodiments, assembly 4 may be fixedly attached or welded, or both assembly 4 and welding may be used.

Referring to fig. 3 and 4, a second embodiment of the present invention provides a frame, which is substantially the same as the first embodiment except that:

preferably, the longitudinal beam 3 is further fixedly connected with the second cross beam 2 through a clamping piece 5, and the clamping piece is located at the end of the longitudinal beam 3.

In order to reduce the weight of the frame and increase the connection strength, the middle parts of the longitudinal beam 3 and the second cross beam 2 are of hollow structures, and the joint of the longitudinal beam and the second cross beam is of a solid structure.

Specifically, joint spare 5 includes screw thread post 51 and joint post 52, screw thread post 51 with longeron 3 screw-thread fit, joint post 52 with the cooperation of 2 joints of second crossbeam.

It can be understood that, during installation, the clamping member 5 can be screwed on the end of the longitudinal beam 3 through the threaded column 51, and then the longitudinal beam 3 can be connected with the second cross beam 2.

Preferably, a reinforcing plate 53 is arranged between the threaded column 51 and the clamping column 52, and the threaded column 51 and the clamping column 52 are fixedly connected with the reinforcing plate 53.

It should be noted that the biggest factor of the longitudinal beam 3 and the second cross member 2 is stress from the lateral direction, which causes the threaded column 51 to bend, and when the reinforcing plate 53 is in contact with the surface of the longitudinal beam 3, the strength of the threaded column 51 is increased, making it difficult to bend.

In addition, longeron 3 with the junction of joint 5 is equipped with holding tank 31, holding tank 31 is used for holding reinforcing plate 53, reinforcing plate 53 with the inner wall contact of holding tank 31 makes longeron 3 can be plane contact with second crossbeam 2.

Specifically, the clamping column 52 extends into the groove 21 of the second beam 2, a cavity 521 is arranged inside the clamping column 52, a top rod 522 and a clamping rod 524 are respectively arranged at the tail end and the side surface of the clamping column 52, the top rod 522 and the clamping rod 524 both penetrate through the surface of the clamping column 52 and extend into the cavity 521, a push block 523 is arranged at one end of the top rod 522 located in the cavity 521, the side surface of the push block 523 is an inclined surface, when the top rod 522 slides towards the cavity 521, the push block 523 pushes the clamping rod 524 to move outwards, an annular groove 22 is arranged on the inner wall of the groove 21 corresponding to the clamping rod 524, and the annular groove 22 is used for being in clamping fit with the clamping rod 524.

Preferably, the inner wall of the groove 21 at the opening of the annular groove 22 is provided with a slope structure.

The working principle of the clamping column 52 is as follows:

when the clamping column 52 is installed downwards, the top rod 522 is located at the lowest end, the clamping rod 524 is in an initial state without contacting with the inner wall of the groove 21, and in the process that the clamping column 52 moves downwards, the top rod 522 contacts with the bottom of the groove 21 and pushes the clamping column 52 to move outwards by using the pushing block 523. During specific installation, the clamping column 52 needs to be forcibly inserted into the groove 21, and when the ejector rod 522 touches the bottom of the groove 21, the ejector rod rebounds upwards, so that the clamping rod 524 is pushed out and slides into the annular groove 22 under the action of the inclined surface structure of the groove 21, and clamping is realized.

When the clamping column 52 is installed upwards, the clamping rod 524 needs to be manually pressed to prevent the clamping rod from falling off, the clamping column 52 is inserted into the groove 21 in the mode, the ejector rod 522 moves downwards under the action of gravity to push the clamping rod 524 to extend out, and in the process that the clamping column 52 slowly moves upwards, the clamping rod 524 can slide into the annular groove 22 to realize clamping.

In this embodiment, the top rod 522 and the locking rod 524 are both made of metal.

A third embodiment of the invention proposes a transformer cabinet, the motor vehicle comprising at least the frames of the first and second embodiments.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example.
