The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0027] See also Figure 1 The present application provides a power supply device 1, which is used to supply power to other electrical devices and is installed on a guide rail 2, so that the power supply device 1 can be moved and fixed on the guide rail 2 according to the location of other electrical devices. The power supply device 1 includes a housing 1000, and the housing 1000 is used to install the power supply device 1 on the guide rail 2.

[0028] For the aforementioned housing 1000, see 1 and Figure 2The housing 1000 provided in the present application cooperates with the guide rail 2, and the housing 1000 includes: a housing 100 and a slide assembly 200. One side of the housing 100 is a mounting plate surface 101, and the mounting plate surface 101 is integrally formed with a first limiting portion 102 and a first mounting portion 103, and the first limiting portion 102 and the first mounting portion 103 are arranged opposite to each other along the first direction X. That is, the first limiting portion 102 and the first mounting portion 103 are both arranged on the mounting plate surface 101. Optionally, along the first direction X, the first limiting portion 102 is arranged at one end of the mounting plate surface 101, and the first mounting portion 103 is arranged at the other end of the mounting plate surface 101; or, when the housing 100 is relatively large, the first limiting portion 102 and the first mounting portion 103 are arranged in the middle area of ​​the mounting plate surface 101 and are arranged relative to each other at intervals, or, the first limiting portion 102 and the first mounting portion 103 are arranged in an area of ​​the housing 100 close to the ground or away from the ground, and are arranged relative to each other at intervals. The slide assembly 200 includes a slide 201 and an elastic member 202, the slide 201 is slidably connected to the first mounting portion 103, the slide 201 and the first limiting portion 102 are used together to clamp the guide rail 2, one end of the elastic member 202 is connected to the mounting plate surface 101, and the other end is connected to the slide 201, and the elastic member 202 is used to push or pull the slide 201 toward the direction of the first limiting portion 102. It should be noted that the housing 100 is provided with a mounting plate surface 101, which means that the mounting plate surface 101 is a part of the housing 100, and the mounting plate surface 101 is a part of the housing 100, and is integrally formed with the housing 100, while the first limiting portion 102 and the first mounting portion 103 are structures obtained by deforming part of the material in the housing 100 directly on the housing 100 through processes such as stamping. Stamping is a processing method that relies on a press and a mold to apply an external force to the housing 1000 so that the housing 1000 undergoes plastic deformation and is formed. Optionally, forging and other processing methods can also be used. The advantage of this one-piece molding is that the processed housing 1000 can meet the purpose of being clamped together with the above-mentioned slide assembly 200 on the guide rail 2 for fixation, and the one-piece housing 1000 has high structural strength, and the overall structure is stable after fixation, which reduces the phenomenon of looseness when multiple parts are matched. Optionally, when the elastic member 202 is set as a compression spring, the slide 201 is pushed to move the slide 201 toward the first limiting portion 102 to the clamping guide rail 2; correspondingly, when the elastic member 202 is set as a tension spring, the slide 201 is pulled to move the slide 201 toward the first limiting portion 102 to the clamping guide rail 2.

[0029] Through the above structure, the shell 1000 is directly clamped on the guide rail 2, and the guide rail 2 is clamped together by the first limiting portion 102 and the slide 201, thereby reducing the parts between the shell 1000 and the guide rail 2, improving the connection strength and stability between the shell 1000 and the guide rail 2, reducing the setting of the mounting plate, simplifying the production process, and reducing the overall weight of the equipment.

[0030] In some embodiments, see Figure 2 . Along the second direction Y, the first limiting body 104 and the second limiting body 105 protruding relative to the mounting plate surface 101 are extended on opposite sides of the shell 100, and the first limiting body 104 and the second limiting body 105 together form the first limiting portion 102. The first limiting body 104 and the second limiting body 105 are used to clamp different positions of the same side of the guide rail 2. The first direction X is perpendicular to the second direction Y, and the first direction X and the second direction Y are both parallel to the mounting plate surface 101. That is, by providing the first limiting body 104 and the second limiting body 105 opposite to each other along the second direction Y, the guide rail 2 is supported, which facilitates the shell 100 to adjust the balance during installation, and further improves the connection strength and stability between the shell 1000 and the guide rail 2. It should be noted that the first limiting body 104 and the second limiting body 105 can be stamped from the plate body where the mounting plate surface 101 is located, or stamped from the plate body adjacent to the mounting plate surface 101; wherein the first limiting body 104 and the second limiting body 105 can be in the shape of a cylinder, a plate body, a prism, an irregular polygonal prism, etc.; optionally, the first limiting body 104 and the second limiting body 105 are relatively arranged on both sides of the mounting plate surface 101 along the second direction Y, so that one side of the fixing rail 2 can be clamped, so that the housing 1000 can be installed on the horizontal rail 2 or the vertical rail 2. When the guide rail 2 is straight, the relatively arranged first limit body 104 and the second limit body 105 can stably and balancedly clamp the shell 1000 to the guide rail 2 without causing unstable clamping due to the first limit body 104 or the second limit body 105 not contacting the guide rail 2; and in some other embodiments, the line connecting the first limit body 104 and the second limit body 105 on the side close to the first mounting portion 103 is parallel to the corresponding side of the guide rail 2 to ensure the stability of the cooperation between the first limit portion 102 and the guide rail 2, thereby facilitating the clamping of the shell 1000 on the inclined guide rail 2.

[0031] For further information, see Figures 2 to 4The housing 100 is provided with a first clamping groove 106 and a second clamping groove 107.

The first clamping groove 106 and the third clamping groove 2011 clamp the clamping guide rail 2 together, and the second clamping groove 107 and the fourth clamping groove 2012 clamp the clamping guide rail 2 together. It can be understood that the lengths of the first snap-in groove 106, the second snap-in groove 107, the third snap-in groove 2011 and the fourth snap-in groove 2012 are greater than or equal to the thickness of the portion of the guide rail 2 snapped into the above-mentioned groove body, thereby reducing errors during material molding and preventing the guide rail 2 from being unable to snap into the above-mentioned snap-in groove.

That is, the first slide rail 108 and the second slide rail 109 together form the first mounting portion 103, so as to facilitate the sliding cooperation between the slide plate 201 and the housing 100. Specifically, the first slide rail 108 is at least partially arranged relative to the mounting plate surface 101 along the third direction Z, and the first slide table 2013 slides between the mounting plate surface 101 and the first slide rail 108.
