DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] A mobile base for an electrical cabinet, such as Figure 1-4 As shown, it comprises a fixed seat 1, wherein a cavity opening upward and to the right is provided in the fixed seat 1, wherein a movable seat 2 is provided in the cavity, and wherein the movable seat 2 can enter / exit the cavity through a movable device 3.

[0026] Specifically, the fixed seat 1 is arranged at the bottom of the electrical cabinet, matches the position of the electrical cabinet, and locates the moving end point of the UPS. The mobile seat 2 is used to place the UPS, and the UPS can be moved in and out of the electrical cabinet by the movement of the mobile seat 2. In addition, since the mobile seat 2 is always placed on the top of the UPS during use, there can be no obstruction during the movement of the mobile seat 2. The cavity opening upward and to the right can ensure the smooth movement of the mobile seat 2. Furthermore, rollers are provided on the outer side of the mobile seat 2. When the mobile seat 2 moves into the fixed seat 1, the rollers are also located in the fixed seat 1.

[0027] As another specific implementation, when the movable base 2 moves to the leftmost end, the movable base 2 is completely located in the cavity. When the movable base 2 moves to the leftmost end, the UPS should be completely located in the electrical cabinet. At the same time, in order to ensure that the fixed base 1 does not interfere with other structures outside, the fixed base 1 should be located in the vertical downward projection plane of the electrical cabinet. Furthermore, when the movable base 2 is completely located in the cavity, the occupied space of the movable base can be reduced, and the maximum space utilization can be achieved.

[0028] As another specific embodiment, the moving device 3 includes a lead screw 31 arranged along the left-right direction and arranged on the fixed seat 1, and the moving seat 2 is also provided with a nut seat 32 coaxial with the lead screw 31, and the nut seat 32 is sleeved on the lead screw 31 and fixedly arranged on the moving seat 2 through a connecting member; the moving seat 2 is provided with a first positioning member 33 for positioning the lead screw 31. Specifically, one of the lead screw 31 and the nut seat 32 is fixedly arranged, and the other is rotatably arranged. The rotatable lead screw 31 or the nut seat 32 is rotated, and its thread is matched with the other component, and then the other component is driven to move by the reaction force, thereby realizing the movement of the moving seat 2.

[0029] As another specific embodiment, a motor 34 is provided at the bottom of the mobile seat 2, and the motor 34 is connected to the lead screw 31 through a connecting assembly 35. Specifically, since the cavity in the fixed seat 1 needs to provide space for the movement of the mobile seat 2, arranging the motor 34 in the fixed seat 1 will cause a part of the space to be unable to overlap with the mobile seat 2, thereby increasing the occupied space. However, the space below the mobile seat 2 is relatively abundant, and arranging the motor 34 there will not interfere with other structures, thereby improving the space utilization rate and facilitating the transportation of the mobile base.

[0030] As another specific embodiment, the connecting assembly 35 includes a transmission chain 351, one end of the transmission chain 351 is connected to the output shaft of the motor 34, the other end of the transmission chain 351 is connected to a rotating shaft 352, the rotating shaft 352 is rotatably connected to the moving seat 2 through a support frame 353, a driving gear 354 is also provided on the rotating shaft 352, and a driven gear 355 is provided on the lead screw 31, and the driving gear 354 and the driven gear 355 are meshed. The gear system can reliably transmit power, maintain precise movement even at high speed or heavy load, and can achieve precise positioning by accurately controlling the rotation of the transmission chain and the gears. Furthermore, the output shaft of the motor 34 and the rotating shaft 352 are also provided with gears for connecting the transmission chain 351. Specifically, the screw 31 is provided with a positioning slot in the circumference so that the outer circumference of the screw 31 is non-circular, and the driven gear 355 is provided with a limiting hole matching the shape of the screw 31, so that the driven gear 355 can move axially along the screw 31 and does not rotate relative to the circumference. In addition, the driven gear 355 is provided between the nut seat 32 and the connecting member, so that the driven gear 355 can be axially positioned. Of course, this embodiment is only an option, and in actual use, other ways of driving the screw 31 to rotate can also be adopted.

[0031] As another specific embodiment, the moving device 3 further includes a guide rod 36 arranged in the left-right direction, and the moving seat 2 is provided with a second positioning member 37 for positioning the guide rod 36. Specifically, the guide rod 36 can play an auxiliary guiding role, thereby cooperating with the lead screw 31 to ensure the smooth movement of the moving seat 2.

[0032] As another specific implementation, the mobile base 2 is further provided with a reinforcing beam 21 arranged along the front-rear direction. The reinforcing beam 21 can increase the structural strength of the mobile base 2, prevent deformation, and ensure that the UPS can be supported.

[0033] As another specific implementation, a plurality of through holes arranged along the left-right direction are provided on the reinforcing beam 21. The through holes can ensure that the movement of the lead screw 31 and the guide rod 36 is not blocked.

[0034] As another specific implementation, the movable seat 2 is provided with a limit normally open travel switch 4, and the fixed seat 1 is provided with a corresponding limit seat 5. Specifically, when the movable seat 2 moves inward to a predetermined position, the limit normally open travel switch 4 contacts the limit seat 5, so as to control the motor 34 to stop running after the UPS is pushed into place.

[0035] As another specific embodiment, the moving seat 2 is provided with a normally closed travel switch 6, and the normally closed travel switch 6 corresponds to the position of the moving device 3. Specifically, the normally closed travel switch 6 contacts the guide rod 36 during the movement of the moving device 3, and when the moving seat 2 moves outward to a predetermined position, the limit normally closed travel switch 6 leaves the guide rod 36, so as to control the motor 34 to stop running after moving out to the desired position.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
