Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a modular power distribution cabinet. Background Art

[0002] With the acceleration of industrialization and urbanization, the demand for electricity has increased significantly, which has led to an increase in the demand for power distribution and management equipment, and the invention of distribution cabinets has been born to prevent safety hazards caused by the use of electricity.

[0003] Most distribution cabinets are usually provided with reserved holes, and predetermined guide rails are fixed to the reserved holes inside the distribution cabinet by bolts, or electronic components are directly fixed to the reserved holes by bolts.

[0004] However, there is at least one of the following problems in the related technology: the distribution cabinets in the related technology have poor versatility. On the one hand, the installation position of the electronic components is fixed and cannot be adjusted according to actual needs. When the electronic components need to be upgraded or maintained, it is often necessary to carry out large-scale transformation of the reserved installation position, which is complicated and difficult to operate. If necessary, the entire distribution cabinet needs to be replaced. On the other hand, the space utilization rate is low, the position of the electronic components cannot be flexibly arranged, and it is difficult to make full use of the internal space of the distribution cabinet. Summary of the invention

[0005] The technical problem solved by the present invention is that the power distribution cabinet in the related technology has poor versatility. On the one hand, the installation position of the electronic components is fixed and cannot be adjusted according to actual needs. When the electronic components need to be upgraded or maintained, it is often necessary to carry out large-scale transformation of the reserved installation position, which is complicated and difficult to operate. If necessary, the entire power distribution cabinet needs to be replaced. On the other hand, the space utilization rate is low, the positions of the electronic components cannot be flexibly arranged, and it is difficult to make full use of the internal space of the power distribution cabinet.

[0006] To solve the above problems, the present invention provides a modular power distribution cabinet, comprising: a box body, a mounting portion is provided in the box body; a plurality of mounting components, all of which are movably arranged in the box body for placing a target object; a supporting mechanism, the supporting mechanism is arranged in the mounting portion, and the supporting mechanism is used to lock the mounting component; the supporting mechanism specifically comprises: a main body part, the main body part comprises a first state and a second state, when the main body part is in the first state, the supporting mechanism locks the mounting component on the box body; when the main body part is in the second state, the supporting mechanism unlocks the mounting component, and the mounting component can slide up and down relative to the box body; a switch component, the switch component is nested in the main body part, and the switch component can move along the axial direction of the main body part; wherein, when the switch component moves away from the main body part along the axial direction, the main body part gradually changes from the first state to the second state; when the switch component moves close to the main body part along the axial direction, the main body part gradually changes from the second state to the first state.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: compared with the related art of directly fixing electronic components to preset hole positions by bolts, the installation assembly in the present invention can slide up and down relative to the box to change the position of the electronic components in the vertical direction, so that the installation position of the electronic components can be flexibly adjusted according to actual needs, making full use of the internal space of the distribution cabinet, so as to better adapt to different wiring requirements and space limitations, and the main body of the support mechanism is controlled by a push-type switch assembly to change between the first state and the second state to achieve locking and unlocking of the installation assembly relative to the box. Compared with the method of fixing electronic components by bolts, the present invention can adapt to the installation needs of electronic components of different specifications and sizes. Whether it is a small electronic component or a large equipment, its installation position can be adjusted to adapt to its size. The operation is more convenient, and there is no need to repeatedly disassemble the bolts, which reduces the manual workload.

[0008] In one example of the present invention, the main body portion includes: a supporting portion and a matching portion; the supporting portion is arranged on the outer surface of the matching portion and is connected to the matching portion; the matching portion is sleeved on the outer side of the switch assembly; wherein, when the supporting portion is on the side close to the matching portion, the main body portion is in the second state; when the supporting portion moves from the side close to the matching portion to the side away from the matching portion, the main body portion gradually changes from the second state to the first state.

[0009] Compared with the prior art, the technical effects achieved by adopting this technical solution are: the specific structure of the main part is further clarified, that is, through the arrangement of the supporting part on the outer surface of the matching part and the connection method with the matching part, the movement process of the supporting part when the main part of the support mechanism is in two states and during the switching process between the two states, as well as the relative positional relationship between the supporting part and the matching part when the main part of the support mechanism is in different states; on the other hand, the design of the matching part being sleeved on the outside of the switch assembly makes the structure of the entire support mechanism more compact and occupies less space.

[0010] In one example of the present invention, a second connecting portion is provided on the outer surface of the mating portion; a first connecting portion is provided on the supporting portion corresponding to the second connecting portion; the main body portion also includes a first connecting member; the first connecting member connects the first connecting portion and the second connecting portion; wherein, when the first connecting member is perpendicular to the first connecting portion and the second connecting portion, the main body portion maintains the first state.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is: when the first connecting member is perpendicular to the first connecting portion and the second connecting portion, the first connecting member and the matching portion form a dead point, so that the main body can maintain the first state unchanged.

[0012] In one example of the present invention, the mating portion is cylindrical, and a slide groove is provided along the length direction of the mating portion, and the slide groove is located on the side of the second connecting portion close to the switch assembly; the mating portion includes a locking end, and the locking end is located on the side of the mating portion away from the switch assembly, and a limiting groove is provided in the locking end; wherein, at least part of the structure of the switch assembly is located in the slide groove, and when close to the second connecting portion, the switch assembly abuts against the limiting groove, and the main body maintains the first state.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the position of the switch assembly is limited by the position of the slide groove and the limit groove. When the switch assembly is in a specific position and abuts against the limit groove, it can effectively prevent the main body from changing between states due to accidents, thereby improving the stability and reliability of the support mechanism.

[0014] In one example of the present invention, the mating portion is provided with a through hole; the switch assembly includes: a pressing portion and a linkage portion; the pressing portion is connected to the linkage portion; the pressing portion is arranged on a side away from the locking end; the linkage portion is arranged in the through hole; a clamping portion is provided on a side of the linkage portion away from the pressing portion; the limiting groove includes a first locking position, and the first locking position is located on a side of the locking end farthest from the pressing portion; wherein, when the clamping portion is clamped with the first locking position, the main body is in a first state.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is: the engaging position of the engaging portion and the limiting groove in the switch assembly is further clarified, and it is pointed out that when the main body is engaged with the limiting groove on the side farthest from the switch assembly, namely the first locking position, the main body is in the first state.

[0016] In one example of the present invention, the limit groove also includes a second locking position, which is located on the side of the locking end closest to the switch assembly; the clamping portion includes a fourth matching hole and a clamping member; the fourth matching hole is located on the side of the clamping portion close to the limit groove; the clamping member is arranged in the fourth matching hole; wherein, when the clamping member is clamped with the second locking position, the main body is in the second state; when the clamping member is clamped with the first locking position, the main body is in the first state.

[0017] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by setting the second locking position and the first locking position to correspond to the second state and the first state of the main body of the supporting mechanism respectively, the locking position of the main body in these two states is clearer, and the snap-on design of the snap-on parts and different locking positions provides a stable locking mechanism for the main body in different states; this design can effectively prevent the main body from switching its state at will due to accidents during use, thereby improving the stability and reliability of the distribution cabinet; and according to different usage requirements of the distribution cabinet, the main body of the supporting mechanism can be flexibly switched between the first state and the second state to adjust the installation position of its electronic components.

[0018] In one example of the present invention, the support portion also includes a support wall, which is arranged on a side of the first connecting portion away from the mating portion; the mounting assembly includes a mounting plate and a tightening member, which is arranged on the mounting plate; the linkage portion includes: a third connecting portion; the third connecting portion is arranged on the outer surface of the linkage portion; wherein, when the second connecting portion and the third connecting portion are vertically collinear, the support wall supports the tightening member so that the tightening member abuts against the inner wall of the mounting portion, thereby locking the mounting plate to the box body.

[0019] Compared with the prior art, the technical effects achieved by adopting this technical solution are: the vertical collinear relationship between the third connecting part and the second connecting part is clarified as a specific working state, which is the dead point state of the supporting mechanism. At this time, the main part in the supporting mechanism can maintain the posture of the first state without being disturbed by external forces, so as to improve the structural strength of the main part and improve the stability of the installation component on the distribution cabinet box; combined with the supporting wall of the supporting part and the tightening piece arranged on the mounting plate, the supporting wall and the tightening piece cooperate with each other, so that when the main part is in the first state, the contact area between the supporting mechanism and the box mounting part is larger, thereby further enhancing the connection strength between the box and the installation component.

[0020] In one example of the present invention, the first connecting member is provided with a third matching hole; the linkage portion also includes a second connecting member, one end of the second connecting member is rotatably connected to the third matching hole, and the other end is rotatably connected to the third connecting portion; wherein, when the second connecting member is colinear with the first connecting member and perpendicular to the supporting portion and the matching portion, the main body portion is in the first state.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by providing a second connecting member rotatably connected to the first connecting member, it is possible to form a linkage with the linkage part of the main part when the switch assembly is pressed, and when the second connecting member is colinear with the first connecting member and perpendicular to the supporting part and the matching part, the first connecting member, the second connecting member and the linkage member further form a dead point of the supporting mechanism, so that the supporting mechanism can maintain the posture of the first state without being disturbed by external forces, so as to improve the overall structural strength of the supporting mechanism.

[0022] In one example of the present invention, the mounting assembly further includes: a snap-fitting member, which is disposed on the mounting plate and can slide left and right along the mounting plate; a partition plate, which is disposed on the snap-fitting member and is used to separate the target objects; and a locking knob, which is disposed on the snap-fitting member and is used to fix the snap-fitting member on the mounting plate.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by arranging a partition plate on the mounting plate, the target objects in the distribution cabinet can be separated according to actual needs, so that components of different types or functions can be arranged independently to avoid mutual interference, so as to improve the rationality of the internal layout of the distribution cabinet; the fasteners that can slide left and right along the mounting plate allow the position of the partition plate to be flexibly adjusted to adapt to target objects of different sizes and layout requirements, thereby improving the adaptability of the distribution cabinet, and reasonable separation can reduce the risk of short circuits or other electrical failures between electronic components, thereby improving the safety of the distribution cabinet.

[0024] In one example of the present invention, an indication module is provided in a box body and connected to a target object to display the working status of the target object; and / or an incoming line module is provided below the indication module and connected to the target object to control and protect the electric energy distributed to the target object; and / or a branch module is provided below the incoming line module and connected to the target object to distribute the total power to the target object; and / or a monitoring module is provided in the branch module and connected to the target object to monitor and collect the electrical parameters and operating status of the target object in the distribution cabinet in real time.

[0025] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] (1) Through the cooperation between the mounting assembly and the supporting mechanism, the mounting assembly can slide up and down relative to the box to change the vertical position of the electronic components in the power distribution cabinet, so that the electronic components can be flexibly adjusted according to actual needs and the internal space of the power distribution cabinet can be fully utilized;

[0027] (2) The main part of the supporting mechanism is controlled to change between the first state and the second state by a push-type switch assembly. Compared with the method of fixing the electronic components by bolts, the operation is more convenient. When the installation position needs to be adjusted, there is no need to repeatedly remove the bolts, thereby reducing the manual workload;

[0028] (3) By setting the dead point position of the main part of the support mechanism, the structural strength of the main part when in the first state is improved to prevent the support mechanism from loosening due to vibration or other external force interference;

[0029] (4) By setting a dead point position where the main body and the switch assembly cooperate with each other, the structural strength of the entire support mechanism when in the first state is improved, and by the cooperation of the contraction parts of the support wall and the mounting plate, the contact area between the support mechanism and the box mounting portion is larger when the support mechanism is in the first state, further enhancing the connection strength between the box and the mounting assembly;

[0030] (5) By setting a partition plate on the mounting plate, the target objects in the distribution cabinet can be separated according to actual needs, so that components of different types or functions can be arranged independently to avoid mutual interference. Reasonable separation of electronic components can reduce the risk of short circuits or other electrical failures between electronic components, thereby improving the safety of the distribution cabinet.

[0056] Optionally, the power distribution cabinet 100 further includes: a door assembly, which is hinged to the box body 10 of the power distribution cabinet 100 , and the door assembly is used to seal the space inside the box body 10 to prevent external dust or impurities from entering the box body 10 .

[0057] See also Figures 2 to 6 Specifically, a mounting frame 11 is provided in the box body 10, and a mounting portion 111 is located at four azimuth angles of the mounting frame 11. The mounting assembly 20 is movably arranged in the mounting portion 111. A first mounting groove 112 is provided on the side of the mounting position close to the door assembly. The support mechanism is connected to the mounting assembly 20 through the first mounting groove 112. The switch assembly 40 is sleeved in the main body 30 of the support mechanism and forms a transmission connection with the switch assembly 40. By pressing the switch assembly 40, the main body 30 is driven to perform an external support action to keep the main body 30 in the first state or to perform a contraction action to keep the main body 30 in the second state.

[0058] See also Figures 7 to 10 Furthermore, the main body part 30 includes: a supporting part 31 and a matching part 32; the supporting part 31 is arranged on the outer surface of the matching part 32 and is connected to the matching part 32; the matching part 32 is sleeved on the outer side of the switch assembly 40; wherein, when the supporting part 31 is on the side close to the matching part 32, the main body part 30 is in the second state; when the supporting part 31 moves from the side close to the matching part 32 to the side away from the matching part 32, the main body part 30 gradually changes from the second state to the first state.

[0059] In combination with specific usage conditions, when the switch assembly 40 is pressed to move away from the main body part 30 in the axial direction, the support portion 31 of the main body part 30 moves from the side close to the matching portion 32 to the side away from the matching portion 32. At this time, the main body part 30 gradually changes to the first state to lock the installation assembly 20 on the box body 10; on the contrary, when the switch assembly 40 moves toward the main body part 30 in the axial direction, the support portion 31 of the main body part 30 moves from the side away from the matching portion 32 to the side close to the matching portion 32. At this time, the main body part 30 gradually changes from the first state to the second state, and the support mechanism unlocks the installation assembly 20. The installation assembly 20 can slide up and down relative to the first installation slot 112 of the installation frame 11 to adjust its position.

[0060] Furthermore, a second connecting portion 322 is provided on the outer surface of the matching portion 32; a first connecting portion 312 is provided on the supporting portion 31 corresponding to the second connecting portion 322; the main body portion 30 also includes a first connecting member 33; the first connecting member 33 connects the first connecting portion 312 and the second connecting portion 322; wherein, when the first connecting member 33 is perpendicular to the first connecting portion 312 and the second connecting portion 322, the main body portion 30 maintains the first state.

[0061] Specifically, there are multiple supporting parts 31, and they are arranged at equal intervals in the circumferential direction around the matching part 32. The first connecting part 312 is provided with multiple first matching holes 313, and the multiple first matching holes 313 are arranged equidistantly along the length direction of the first connecting part 312; there are multiple second connecting parts 322, and they are arranged equidistantly along the length direction of the matching part 32, and the second matching part 32 is provided with second matching holes 3221 corresponding to the first matching holes 313; the first connecting member 33 is rotatably connected to the first matching hole 313 and the second matching hole 3221.

[0062] Furthermore, the mating portion 32 is cylindrical, and a slide groove 323 is provided along the length direction of the mating portion 32, and the slide groove 323 is located on the side of the second connecting portion 322 close to the switch assembly 40; the mating portion 32 is divided into two parts, namely a locking end 324 and a non-locking end which are arranged opposite to each other, the locking end 324 is located on the side of the mating portion 32 away from the switch assembly 40, and the non-locking end is located on the side of the mating portion 32 close to the switch assembly 40; wherein a limiting groove is provided in the locking end 324, and when at least part of the structure of the switch assembly 40 is located in the slide groove 323 and close to the second connecting portion 322, the switch assembly 40 abuts against the limiting groove of the locking end 324, so that the main body 30 maintains the first state.

[0063] It should be noted that the present application does not make any specific limitation on the setting position of the slide groove 323. The setting position of the slide groove 323 can be as described in the above paragraph, or it can be set between any two adjacent second connecting parts 322. It should be noted that when the setting position of the slide groove 323 is changed, the setting positions of the third connecting part 421 and the second connecting member 43 that cooperate therewith should also be adjusted accordingly. The present application will not give any examples here.

[0064] Preferably, there are multiple limiting grooves; by providing multiple limiting grooves, the support mechanism can adapt to installation grooves or installation positions of different sizes and diameters, so as to improve the overall versatility of the support mechanism.

[0065] Furthermore, the matching portion 32 is provided with a through hole 321; the switch assembly 40 includes: a pressing portion 41 and a linkage portion 42; the pressing portion 41 is connected to the linkage portion 42; the pressing portion 41 is arranged on a side away from the locking end 324; the linkage portion 42 is arranged in the through hole 321; a clamping portion 422 is provided on a side of the linkage portion 42 away from the pressing portion 41; the limiting groove includes a first locking position 3211, and the first locking position 3211 is located on a side of the locking end 324 farthest from the pressing portion 41; wherein, when the clamping portion 422 is clamped with the first locking position 3211, the main body 30 is in the first state.

[0066] Preferably, a recess 411 is provided on a side of the pressing portion 41 away from the linkage portion 42 to facilitate pressing by an operator.

[0067] Furthermore, the limiting groove also includes a second locking position 3212, and the second locking position 3212 is located on the side of the locking end 324 closest to the switch assembly 40; the clamping portion 422 includes a fourth matching hole 4221 and a clamping member 423; the fourth matching hole 4221 is located on the side of the clamping portion 422 close to the limiting groove; the clamping member 423 is arranged in the fourth matching hole 4221; wherein, when the clamping member 423 is clamped with the second locking position 3212, the main body 30 is in the second state; when the clamping member 423 is clamped with the first locking position 3211, the main body 30 is in the first state.

[0068] In combination with specific usage, when the switch assembly 40 is pressed, the clamping part 423 is compressed and moves into the fourth matching hole 4221 until the clamping part 423 moves to any limit groove, at which time the external force acting on the clamping part 423 disappears and the deformation is restored, and the clamping part 423 abuts against the corresponding limit groove, so that the main part 30 of the support assembly maintains the corresponding supporting action.

[0069] Furthermore, the clamping member 423 includes a mating end 4231 and an elastic member 4232. The elastic member 4232 is arranged on one side of the mating end 4231 close to the fourth mating hole 4221. The shape of the mating end 4231 is adapted to the limiting groove. The mating end 4231 is spherical and the elastic member 4232 is a spring.

[0070] Preferably, there are two fourth matching holes 4221, and the number of the clamping members 423 corresponds to the number of the second matching holes 3221; the two symmetrically arranged fourth matching holes 4221 help to keep the switch assembly 40 balanced when the clamping member 423 is clamped with the limiting groove.

[0071] It should be noted that the first locking position 3211 and the second locking position 3212 in the above content are set in combination with the specific structure of the support mechanism.
