Because the support plate is provided with the ventilation holes, when the fan 160 works, air on two sides of the support plate 162 can circulate, so that heat dissipation of electrical components and cable wires inside the cabinet 110 can be better achieved.
In an embodiment, the first driving portion 161 is disposed on the supporting plate 162, so as to support the first driving portion 161.
In an embodiment, the support plate 162 further includes a filter screen 163, and the filter screen 163 is disposed in the airing hole 102 to prevent external foreign matters from entering into a portion of the cabinet body for accommodating the electric components and the cable wires through the support plate 162, thereby enabling more stable operation of the electric components and the cable wires.
In one embodiment, the power distribution cabinet 100 further includes a lifting mechanism and a moving mechanism. The lifting mechanism is located inside the cabinet 110 and is connected with the side wall of the cabinet 110. The moving mechanism is connected with the lifting mechanism, the lifting mechanism drives the moving mechanism to lift along the second direction, and the moving mechanism is used for moving the power distribution cabinet 100.
Specifically, the lifting mechanism can move up and down along the vertical direction inside the cabinet 110, and when the lifting mechanism moves along the vertical direction, the lifting mechanism can be driven to lift along the vertical direction, so that the lifting mechanism can extend out of the cabinet 110 or retract into the cabinet. When the power distribution cabinet 100 needs to be moved, the lifting mechanism enables the moving mechanism to extend out of the cabinet body, so that the power distribution cabinet 100 can be supported on the ground, and the power distribution cabinet 100 can be moved through the moving mechanism; when the power distribution cabinet 100 does not need to be moved, the lifting mechanism drives the moving mechanism to retract into the cabinet body 110, so that the power distribution cabinet 100 is in contact with the ground and can be stably supported by the ground.
Referring to FIG. 8, in one embodiment, the movement mechanism includes a base plate 1841 and wheels 1842. The base plate 1841 is connected to a lifting mechanism. Wheels 1842 are coupled to an end of the base plate 1841 facing away from the lift mechanism.
Specifically, the lifting mechanism is connected to the base plate 1841, so that the lifting mechanism can drive the base plate 1841 to lift when lifting. Because the wheels 1842 are connected with one end of the bottom plate 1841, which is far away from the lifting mechanism, when the bottom plate 1841 lifts the mechanism along with the lifting mechanism, the wheels 1842 can lift, so that the wheels 1842 can extend out of the cabinet body 110 or retract into the cabinet body 110, (beneficial effects) when the wheels 1842 extend out of the cabinet body 110, the power distribution cabinet 100 can be driven to move, and the transfer of the power distribution cabinet 100 is completed; when the wheels 1842 are retracted into the cabinet 110, the power distribution cabinet 100 contacts the ground, and the power distribution cabinet 100 can be used normally.
In this embodiment, the wheels 1842 may be universal wheels, pulleys, or the like.
Referring to fig. 8, in an embodiment, the lifting mechanism includes a force input member 181, a lifting portion 182, and a transmission portion 183. The transmission section 183 is connected to the force input member 181. And the transmission part 183 is used for driving the lifting part 182 to move along the second direction.
Specifically, the force input member 181 is connected to the transmission portion 183, so that the force input member 181 can drive the transmission portion 183 to move, and the movement of the transmission portion 183 causes the lifting portion 182 to move in the vertical direction, thereby driving the moving mechanism to extend out of the cabinet 110 or retract into the cabinet 110.
Referring to fig. 1, in an embodiment, the lifting mechanism further includes a fixing plate 1834, the fixing plate 1834 is connected to a side wall of the cabinet 110, and the second driving assembly is disposed on the fixing plate 1834, so that the fixing plate 1834 can support the second driving assembly.
Referring to fig. 8, in one embodiment, the transmission portion 183 includes a first gear 1831, a second gear 1832, and a belt 1833. The first gear 1831 rotates coaxially with the force input member 181. The belt 1833 encircles and tightens against the first gear 1831 and the second gear 1832. The lifting portion 182 is a second ball screw 1821, and the second gear 1832 rotates coaxially with a second nut 1823 of the second ball screw 1821 to drive the second screw 1822 of the second ball screw 1821 to move in a second direction.
Specifically, the force input member 181 is capable of rotating the first gear 1831, and the belt 1833 is wound around and tensioned on the first gear 1831 and the second gear 1832, i.e. the first gear 1831 indirectly drives the second gear 1832 to rotate through the transmission of the belt 1833. Because the second gear 1832 rotates coaxially with the second nut 1823 of the second ball screw 1821, the second gear 1832 can drive the second nut 1823 to rotate when rotating, so that the second screw 1822 moves up and down along the vertical direction, thereby realizing the lifting function.
In one embodiment, second screw 1822 is coupled to base plate 1841 through a fixed plate 1834, thereby enabling second screw 1822 to move up and down as base plate 1841 is moved up and down in a vertical direction.
Referring to fig. 8 and 9, in an embodiment, the power distribution cabinet 100 further includes a buffer assembly 190, where the buffer assembly 190 includes a diagonal rod 191, an elastic assembly, and a sliding portion 193. The diagonal member 191 is inclined to the second direction, and one end of the diagonal member 191 is rotatably connected to the bottom plate 1841. The elastic member is rotatably coupled to the other end of the diagonal 191 and coupled to the wheel 1842 for resisting an impact force from the second direction received by the wheel 1842. The sliding portion 193 is connected with the elastic component, and the sliding portion 193 is in sliding fit with a chute formed in the power distribution cabinet 100 along the second direction.
Specifically, when the power distribution cabinet 100 receives an upward impact force due to jolt during moving the accessory cabinet 100, that is, the wheels 1842, the elastic members, and the sliding portion 193 receive an upward impact force, the inclined bar 191 has a reduced tendency to form an angle (acute angle) with the bottom plate 1841, and the sliding portion 193 slides upward. Because the elastic member is coupled to the wheel 1842, the elastic force of the elastic member counteracts a portion of the upward impact force, slows down the upward sliding of the sliding portion 193, and resists the tendency of the diagonal rod 191 to decrease at an angle (acute angle) with the bottom plate 1841, thereby alleviating jerk.
Similarly, when the power distribution cabinet 100 receives an upward impact force due to jolt, the buffer assembly can also alleviate jolt of the power distribution cabinet.
Because the sliding portion 193 is connected with the elastic component, and the sliding portion 193 is slidably matched with the sliding groove formed in the cabinet 110 along the second direction, the buffer component 190 can move along the vertical direction along with the bottom plate 1841, so that the buffer component can extend out of the cabinet 110 or retract into the cabinet 110 with the wheels 1842.
Referring to fig. 8 and 9, in one embodiment, the resilient assembly includes a fixed rod 1921, a spring 1922, and a movable plate 1923. One end of the fixing lever 1921 in the first direction is fixedly connected to the sliding portion 193. The spring 1922 is sleeved on the fixing rod 1921. The movable plate 1923 is connected with the spring 1922, and the movable plate 1923 is rotatably connected with the other end of the diagonal 191, and the movable plate 1923 is fixedly connected with the wheel 1842.
Specifically, when the power distribution cabinet 100 receives an upward impact force due to jolt during moving the accessory cabinet 100, the movable plate 1923 tends to move upward. Because the movable plate 1923 is rotationally connected with the other end of the diagonal member 191, when the movable plate 1923 has a trend of moving upwards, the diagonal member 191 rotates, and because one end of the diagonal member 191 is rotationally connected with the bottom plate 1841, when the diagonal member 191 rotates, an acute angle between the diagonal member 191 and the bottom plate 1841 has a trend of reducing, and therefore the diagonal member 191 drives the movable plate 1923 to move along the horizontal direction. Because the movable plate 1923 is connected with the spring 1922, in the process that the movable plate 1923 moves horizontally, the elastic force of the spring 1922 counteracts a part of the acting force along the horizontal direction, so that the power distribution cabinet 100 can buffer a part of the impact force when in a bumpy road section.
