Referring to fig. 1, in order to illustrate a preferred embodiment of the present invention, the device mounting structure assembly includes three directional components, including: at least one cabinet upright 100 extending along the Z-direction, wherein a plurality of equidistant Z-direction mounting holes 110 are formed on the cabinet upright 100; at least one cabinet side beam 200 extending along the Y direction, fixedly mounted with the cabinet upright 100, and having a plurality of equally spaced Y-direction mounting holes 210; at least one device mounting beam 300 extending along the X direction is mounted on the Z direction mounting hole 110 or the Y direction mounting hole 210, and a plurality of equidistant first X direction mounting holes 310 and second X direction mounting holes 320 for mounting the device 400 are formed thereon, wherein the first X direction mounting holes 310 are kidney-shaped holes.

The Y-direction mounting holes 210 in the cabinet side members 200 can realize equidistant changes in the Y direction (depth direction), and the Z-direction mounting holes 110 in the cabinet uprights 100 can realize equidistant changes in the Z direction (height direction) of the component mounting beams 300. The X-direction first mounting hole 310 and the X-direction second mounting hole 320 on the device-mounting beam 300 may implement various mounting manners to implement stepless variation of the pitch in the X-direction (horizontal direction). For example, the present application may mount the device 400 on the left or right end of a certain X-direction first mounting hole 310 and the X-direction second mounting hole 320 adjacent thereto; or mounting the device 400 on the left end of one X-direction first mounting hole 310 and the right end of another X-direction first mounting hole 310 adjacent thereto; or the device 400 is mounted at the left end or the right end of a certain X-direction first mounting hole 310; or the device 400 is mounted at the left and right ends of a certain X-direction first mounting hole 310. Therefore, the pitch of the device mounting beams 300 in the X direction can be smoothly and continuously varied by any value of 0 or more, and any pitch of the device mounting holes 400 can be adapted. The above components are described in further detail below.

In one embodiment of the present application, the cabinet side member 200 is mounted to the Z-direction mounting hole 110. In another embodiment of the present application, the cabinet upright 100 is mounted on the Y-direction mounting hole 210. The two embodiments are similar in principle and structure, and only the installation of the cabinet side member 200 in the Z-direction installation hole 110 will be described in detail.

Preferably, the position of the device 400 can also be varied equidistantly in the Y-direction. The device mounting beam 300 further has a first fixing hole 330 for being matched and fixed with the Y-direction mounting hole 210, and the first fixing hole 330 is a waist-shaped hole. The Y-direction mounting hole 210 of the cabinet side member 200 is fitted to the first fixing hole 330 having a waist shape, the cabinet side member 200 is mounted to an arbitrary position (for example, an end portion or a middle portion of the waist-shaped hole) of the first fixing hole 330 having a waist shape by a fastener (not numbered in the figure), and the plurality of equally spaced Y-direction mounting holes 210 are fitted, thereby realizing stepless change of the device mounting beam 300 in the Z-direction.

As shown in fig. 1, cabinet upright 100, cabinet side member 200, and device mounting member 300 are all C-shaped members. Wherein, in order to guarantee the steadiness of installation, there are four cabinet stand 100 in quantity, all extend along the Z direction. A plurality of equidistant Z-direction mounting holes 110 are formed on the cabinet upright 100. Preferably, the Z-direction mounting holes 110 are circular holes arranged in a plurality of rows.

Preferably, cabinet side rails 200 are fixedly mounted in pairs on cabinet uprights 100 in parallel to each other. A plurality of equidistant Y-direction mounting holes 210 arranged along the Y-direction are formed in the cabinet side member 200. When Y-direction mounting hole 210 and Z-direction mounting hole 110 are used in cooperation with a fastener (not shown), cabinet side member 200 can be fixedly mounted on cabinet upright 100.

Preferably, the Y-direction mounting holes 210 are provided in three rows in the Z-direction. The advantage of providing three rows of Y-direction mounting holes 210 is: in order to secure the structural strength of the component mounting beam 300, when the length of the waist-shaped hole of the first fixing hole 330 of the below-described component mounting beam 300 is set to be small or when the relative position between the component mounting beam 300 and the cabinet side member 200 can be changed only within a small range, a large connecting contact area can be maintained between the component mounting beam 300 and the cabinet side member 200, so that the mounting stability of the component mounting beam 300 can be improved.

As shown in fig. 2, a perspective view of the device mounting beam 300 is illustrated. The device-mounting beam 300 is preferably formed by bending a sheet metal. There are two rows of equidistant X-direction first mounting holes 310 and X-direction second mounting holes 320 on the front surface of the device mounting beam 300. The first mounting hole 310 in the X direction is a kidney-shaped hole, and the second mounting hole 320 in the X direction is a circular hole. All the X-direction first mounting holes 310 and the X-direction second mounting holes 320 are arranged in bilateral symmetry about the center of the device mounting beam 300, and the X-direction first mounting holes 310 and the X-direction second mounting holes 320 are arranged at intervals and in an equidistant array.

First fixing holes 330 are formed in left and right end surfaces (perpendicular to surfaces where the first mounting hole 310 in the X direction and the second mounting hole 320 in the X direction are located) of the device mounting beam 300, and the first fixing holes 330 are kidney-shaped holes. Preferably, the left and right end surfaces of the device mounting beam 300 are opened with second fixing holes 340, and the second fixing holes 340 are circular holes. The first fixing hole 330 and the second fixing hole 340 are used for being connected and fixed with the cabinet side beam 200.

Preferably, the number of the first fixing holes 330 and the second fixing holes 340 is two, and the specific arrangement may be in various ways, but the first fixing holes 330 and the second fixing holes 340 should be arranged along the same straight line in the Z direction. For example, as shown in fig. 3, two of the first fixing holes 330 and two of the second fixing holes 340 are diagonally staggered; or, for example, as shown in fig. 4, two first fixing holes 330 and two second fixing holes 340 are respectively distributed in parallel in the same row. The first fixing holes 330 and the second fixing holes 340 are combined in two rows, so that the symmetrical use of the device mounting beam 300 can be realized, and the requirements of different distances from the first mounting hole 310 in the X direction and the second mounting hole 320 in the X direction to the outer frame of the device 400 can be met.

Preferably, as shown in fig. 2, a row of third fixing holes 350 is formed on each of left and right sides of the device mounting beam 300, that is, on each of left and right sides of all the X-direction first mounting holes 310 and the X-direction second mounting holes 320. In this embodiment, the third fixing holes 350 are circular holes.

The third fixing hole 350 is used in cooperation with an "L" shaped fixing member 360, and may be used for further position fixing of the device-mounting beam 300. Specifically, when the device mounting beam 300 is not fixedly connected to the Y-direction mounting hole 210 of the cabinet side member 200 through the second fixing hole 340, but is located at an upper or lower position as described above, i.e., is fixedly connected to the Y-direction mounting hole 210 of the cabinet side member 200 only through the first fixing hole 330, a fixing member 360 may be added at the connecting corner between the device mounting beam 300 and the cabinet side member 200, so as to fix the position of the device mounting beam 300, which is beneficial to increase the stability of the mounting structure of the device 400.

As shown in fig. 5, the array pitch of the X-direction first mounting holes 310 and the X-direction second mounting holes 320 of the device mounting beam 300 is 2a, and the center distance between two adjacent X-direction first mounting holes 310 and two adjacent X-direction second mounting holes 320 is a; the diameter of the X-direction second mounting hole 320 and the width of the X-direction first mounting hole 310 are both Φ; the center distance of the semicircle at the two ends of the first mounting hole 310 in the X direction is b; in order to ensure the strength of the device mounting beam 300 after being holed, the minimum distance between the semicircles of the adjacent X-direction first mounting hole 310 and the X-direction second mounting hole 320 is c, and c should be greater than a certain value. The specific value of c is related to the modulus of elasticity and the elongation at break of the device-mounting beam 300.

As shown in fig. 5, when the device 400 is mounted on the device mounting beam 300 in the X direction, there are three corresponding cases between the mounting hole of the device 400 and the X-direction first mounting hole 310 or the X-direction second mounting hole 320 of the device mounting beam 300:

in the first case, the mounting hole of the device 400 corresponds to the adjacent X-direction first mounting hole 310 and the X-direction second mounting hole 320 on the device mounting beam 300; in case two, the mounting holes of the device 400 correspond to two adjacent X-direction first mounting holes 310 on the device mounting beam 300; case three is where the mounting hole of the device 400 corresponds to one X-direction first mounting hole 310 on the device mounting beam 300.

In case one, the pitch of the mounting holes of the device 400 that can be satisfied is: ((a-b/2) to (a + b/2)) + n · 2a, for example a =25, b =20, the pitch of the mounting holes of the device 400 is (15 to 35) +50 · n, n being a natural number;

in case two, the pitch of the mounting holes of the device 400 that can be satisfied is: where = ((2 a-b) - (2a + b)) + n · 2a, for example a =25, b =20, the pitch of the mounting holes of the device 400 is (30-70) +50 · n, n being a natural number;

in case three, the device 400 can satisfy the mounting hole pitch of 0 to b, and if b =20 is taken as an example, the device 400 has the mounting hole pitch of 0 to 20.

The above three cases can satisfy any value change of the pitch of the mounting holes of the device 400 above 0, that is, the pitch of the mounting holes of the device 400 in the X direction can be steplessly changed.

Theoretically, when b = a, the case two can satisfy the requirement of stepless change of the mounting hole pitch x value of the device 400. This patent design is the first mounting hole 310 of X direction and the interval distribution of X direction second mounting hole 320, then can satisfy some devices 400 and install in the condition of situation one, and X direction second mounting hole 320 can pinpoint devices 400 for the circular port, reduces installation error. When some of the devices 400 are mounted in case two or case three, an additional structure (not shown) is added to assist in positioning the devices 400.

As shown in fig. 6, two cabinet side beams 200 are respectively connected and fixed to two cabinet uprights 100, and two device mounting beams 300 are respectively connected and fixed to two cabinet side beams 200. The cabinet upright 100 is provided with Z-direction mounting holes 110 (the distance between adjacent Z-direction mounting holes 110 is d 1) with equal distance d, the cabinet side beam 200 is provided with three rows of Y-direction mounting holes 210 (d 2 is the distance between adjacent Z-direction mounting holes 210) with equal distance d/2 (Z direction), the array distance is e (Y direction), the side surface of the device mounting beam 300 is provided with a first fixing hole 330 and a second fixing hole 340, as shown in fig. 6, the distance between the left and right first fixing hole 330 and the second fixing hole 340 is e, the center distance (d 3) between two semicircles at two ends of the first fixing hole 330 is d/2, and the distance (d 4) between the second fixing hole 340 and the farthest semicircle of the first fixing hole 330 is d.

The distance between the mounting holes of any two rows of the devices 400 between the two device mounting beams 300 is z, and as shown in fig. 7, the value of z can be steplessly adjusted by:

the center distance between the two cabinet side beams 200 is 2d + d.n, n is a natural number, and d is an equal difference number to be changed in an increasing mode. The center distance between the two corresponding device mounting beams 300 is also changed in increments by d as an arithmetic difference.

When the position of one of the device mounting beams 300 is fixed, the relative position between the other device mounting beam 300 and the cabinet side beam 200 can be adjusted in the Z direction: as shown in FIG. 6, the distance adjustable upward is 0-d/2 and the distance adjustable downward is 0-d/2. Therefore, the center-to-center distance between the two device mounting beams 300 is adjustable in the range of 0 to d. In combination with the above, the center distance between the two cabinet side members 200 may be increased by d as an equal difference, and the distance between the two device mounting members 300 may be varied steplessly. Therefore, the mounting hole pitch z of the device 400 between the two device mounting beams 300 can also be steplessly changed. The value of d in fig. 6 and 7 is the same value.

Since the closest distance between the two device mounting beams 300 is the minimum z0 of the mounting hole pitch of the device 400 when the two are close to each other, as shown in fig. 8.

Since the Y-direction mounting holes 210 are provided at equal distances e in the cabinet side member 200, the component mounting beams 300 can be adjusted in the Y direction with e being an equal difference, and the positions of the components 400 in the Y direction can be adjusted with e being an equal difference. The value of e can be designed to be as small as possible, for example, e = d/2, taking into account the structural strength and the screw space.

As described above, by the above structure and the fixing method, we can realize the stepless change of the device hole spacing z above a certain value z 0; the stepless change of the distance x between the device mounting holes more than 0 can be realized; the device can be subjected to a certain equal difference value change in the Y-direction position, so that the mounting requirements of most devices can be met.

The device mounting structure subassembly of this application passes through the pitch-row collocation of rack stand 100, rack curb girder 200, device installation roof beam 300, arranges the design through the first mounting hole 310 of X direction, the X direction second mounting hole 320 that are waist shape on the device installation roof beam 300, can realize adopting the same part to install fixed purpose to different devices 400. The cabinet upright post 100, the cabinet side beam 200 and the device mounting beam 300 can be applied to mounting devices 400 of different specifications and different manufacturers, so that the standardization of parts is realized, and the mass production is facilitated.

The cabinet upright post 100, the cabinet side beam 200 and the device mounting beam 300 can be used as one or more standard parts (different due to different sizes of cabinets), are suitable for mounting structures of devices 400 of most power supply systems, and are beneficial to standardized production of the parts.

For different diameters of the mounting holes of the device 400, the first mounting hole 310 in the X direction and the second mounting hole 320 in the X direction on the device mounting beam 300 may be designed to have a certain diameter, which is compatible with most diameters of the mounting holes of the device 400, or may be adapted to a larger or smaller diameter of the mounting hole through other adapter structures.

The above description is only a preferred embodiment of the present invention, and many changes can be made in the detailed description and the application scope according to the idea of the present invention for those skilled in the art, which all belong to the protection scope of the present invention as long as the changes do not depart from the concept of the present invention.
