Description

Technical Field

[0001] The present invention relates to a standby chassis, in particular to a chassis used for electrical equipment and having a slidable bearing bracket. Background Art

[0002] The arrangement of multiple electrical components within the interior space of existing electrical control boxes is pre-planned during design. An upright distribution tray is fixedly mounted on the rear wall of the box, upon which the electrical components are assembled, configured, and wired. However, due to the limited number of electrical components that the distribution tray can accommodate, and the inability to position additional electrical components in front of these components, the interior space of the box can only accommodate a small number of these components. This also makes it difficult and challenging to expand the distribution tray with additional electrical components later in use.

[0003] Furthermore, when the electrical control box malfunctions and the electrical components need to be repaired, each component assembled on the distribution board must be inspected one by one to identify the faulty component for repair or replacement. This consumes a significant amount of inspection and repair man-hours, causing the production line to shut down and impacting its productivity. Summary of the Invention

[0037] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] Before the present invention is described in detail, it should be noted that similar components are denoted by the same reference numerals in the following description.

[0039] See Figure 1 and Figure 2The first embodiment of the chassis 100 of the present invention is an electric control box for an electrical device. The chassis 100 comprises a box body 1, two door panels 2, a plurality of supporting brackets 3, a plurality of pairs of shock absorbers 4, and a plurality of pairs of limit covers 5 (such as Figure 6 As shown, Figure 6 Only one pair of limit covers 5) is shown.

[0040] For the convenience of subsequent description, the chassis 100 is defined as having a vertical direction Z, a first horizontal direction X perpendicular to the vertical direction Z, and a second horizontal direction Y perpendicular to the vertical direction Z and the first horizontal direction X. The vertical direction Z is the up-down direction, the first horizontal direction X is the front-to-back direction, and the second horizontal direction Y is the left-to-right direction.

[0041] See Figure 2 and Figure 3 The box body 1 includes a bottom wall 10, a top wall 11 opposite to the bottom wall 10, two side walls 12 connected between the bottom wall 10 and the top wall 11 and spaced apart along the second horizontal direction Y, and a plurality of pairs of guide rail assemblies 13 spaced apart along the vertical direction Z. The bottom wall 10, the top wall 11, and the side walls 12 collectively define a receiving space 14, and two openings 15 connected to opposite ends of the receiving space 14 and spaced apart along the first horizontal direction X.

[0042] The two guide rail groups 13 of each pair of guide rail groups 13 are arranged on the inner side of the side wall 12 in opposite directions along the second horizontal direction Y and are located in the accommodating space 14. Each of the guide rail groups 13 includes two first guide rails 16 spaced apart along the vertical direction Z, and a second guide rail 17 located between the first guide rails 16. Each of the first guide rails 16 includes two rails 18 spaced apart and arranged in opposite directions along the vertical direction Z. Each of the rails 18 extends along the first horizontal direction X and is formed with two slots 19 respectively adjacent to the opening 15. The length of each rail 18 extending along the first horizontal direction X is the same as the length of the corresponding side wall 12 extending along the first horizontal direction X. The second guide rail 17 extends along the first horizontal direction X, and the length of the second guide rail 17 extending along the first horizontal direction X is less than the length of the rail 18 extending along the first horizontal direction X.

[0043] See Figure 1 and Figure 2The door panels 2 are connected to the two opposite ends of the box body 1 and are spaced apart along the first horizontal direction X. Each door panel 2 includes a plate body 21 and a plurality of hinges 22 connected between the plate body 21 and the corresponding side wall 12. The plate body 21 can be moved relative to the box body 1 in a closed position (such as Figure 1 As shown), and an opening position of the corresponding opening 15 (as shown Figure 2 shown).

[0044] See Figure 3 and Figure 4 Each of the support brackets 3 includes a support plate 31 and two sliding mechanisms 32 disposed on opposite sides of the support plate 31. The support plate 31 has a bottom surface 311, a support top surface 312 opposite to the bottom surface 311, two side surfaces 313 connected between the bottom surface 311 and the support top surface 312 and spaced apart along the second horizontal direction Y, and two end surfaces 314 connected between the bottom surface 311 and the support top surface 312 and spaced apart along the first horizontal direction X. The support top surface 312 is used to support and secure a distribution tray (not shown). The distribution tray can be equipped with multiple related electrical components (not shown) as required.

[0045] The sliding mechanism 32 is disposed on the side surface 313 opposite to the second horizontal direction Y and is slidably connected to the corresponding pair of guide rail assemblies 13 along the first horizontal direction X. Each of the supporting brackets 3 can be selectively removed from or assembled to the corresponding pair of guide rail assemblies 13 through the corresponding opening 15. Each sliding mechanism 32 includes a telescopic rod 33 and two roller assemblies 34. The telescopic rod 33 includes a fixed rod body 331 and two telescopic rod bodies 332. The fixed rod body 331 has a hollow rod portion 333 and a slider portion 334. The inner surface of the hollow rod portion 333 is fixedly connected to the corresponding side surface 313, for example, by welding. The top of the hollow rod portion 333 is formed with a plurality of positioning holes 335 spaced apart along the first horizontal direction X. The slider portion 334 is protruding from the outer surface of the hollow rod portion 333 and is slidably connected to the second guide rail 17 of the corresponding guide rail assembly 13. The telescopic rods 332 are arranged in opposite directions along the first horizontal direction X. Each telescopic rod 332 includes a telescopic rod portion 336 that partially extends through the hollow rod portion 333, and an elastic fastener 337 disposed on the telescopic rod portion 336 and partially protruding from the top end of the telescopic rod portion 336. The telescopic rod portion 336 is capable of telescoping relative to the fixed rod 331 along the first horizontal direction X and has an end surface 338 that is exposed from the hollow rod portion 333. The elastic fastener 337 can be, for example, a spring pin that is held protruding from the top end of the telescopic rod portion 336 by a spring force, or a V-shaped spring fastener with a locating pin. The elastic fastener 337, located adjacent to the end of the telescopic rod portion 336 opposite the end surface 338, is configured to engage with the corresponding locating hole 335 to lock the telescopic rod 332 to the fixed rod 331.

[0046] The roller assembly 34 is disposed in the opposite direction of the first horizontal direction X to the end surface 338 of the telescopic rod body 332, which is away from each other. Each roller assembly 34 includes a bracket 341, a pivot 342, a pivot rod 343, and a roller 344. The bracket 341 has a connecting plate 345 and two side plates 346 protruding from opposite sides of the connecting plate 345 and spaced apart along the second horizontal direction Y. The connecting plate 345 is fixedly connected to the corresponding end surface 338, for example, by welding or screwing. The pivot 342 is disposed on the side plate 346, and the axial direction of the pivot 342 extends along the second horizontal direction Y. The pivot rod 343 is L-shaped and rotatably pivoted to the pivot 342. The roller 344 is rotatably pivoted to the end of the pivot rod 343 and slidably connected to the corresponding first guide rail 16. The pivot rod 343 can drive the roller 344 to a first downward angular position (such as Figure 3 ), and a second upward angular position (as shown Figure 3 The first angular position and the second angular position are 180 degrees apart, and in the first angular position and the second angular position, the pivot rod 343 is perpendicular to the corresponding telescopic rod body 332.

[0047] See Figure 3 and Figure 5 Each pair of vibration dampers 4 has two vibration dampers 4 disposed at opposite ends of the corresponding pair of guide rail assemblies 13 along opposite directions in the first horizontal direction X. Each vibration damper 4 comprises a frame 41 and three buffer assemblies 42 disposed on the frame 41. The frame 41 includes a horizontal frame 411 extending along the second horizontal direction Y, and two vertical frames 412 connected to opposite sides of the horizontal frame 411 and spaced apart along the second horizontal direction Y. The horizontal frame 411 has a bottom plate 413, a top plate 414 positioned above the bottom plate 413, and an end plate 415 connected between the bottom plate 413 and the top plate 414. Each vertical frame 412 has a vertical rod 416 and two buckle assemblies 417 disposed at one end of the vertical rod 416 and spaced apart along the vertical direction Z. Each buckle assembly 417 has two hooks 418 disposed on the vertical rod 416 and spaced apart along the vertical direction Z. Each of the hooks 418 is used to snap into the corresponding slot 19 of the corresponding rail 18, so that the frame 41 can be fixed to the corresponding pair of guide rails 13. Each of the hooks 418 can be pulled to bend and deform relative to the vertical rod 416 and then disengage from the corresponding slot 19 to release the snap state, so that the frame 41 can be moved away from the corresponding pair of guide rails 13. By snapping each of the hooks 418 into the corresponding slot 19 to release the snap state, each of the shock absorbers 4 can be removably assembled to the corresponding pair of guide rails 13 through the corresponding opening 15. Since each of the shock absorbers 4 can be assembled to or disassembled from the corresponding pair of guide rails 13 without the assistance of other tools, the convenience of assembly or disassembly can be effectively improved.

[0048] In the first embodiment, each of the buffer components 42 is a buffer strip made of an elastic material, such as, but not limited to, polyvinyl chloride (PVC). The buffer components 42 are elongated and their lengths extend along the second horizontal direction Y. The buffer components 42 are respectively adhered to the inner surface of the bottom plate 413, the inner surface of the top plate 414, and the inner surface of the end plate 415, for example, by adhesive bonding, and are respectively used to abut the bottom surface 311, the top surface 312, and the corresponding end surface 314 of the corresponding support plate 31.

[0049] See Figure 4 、 Figure 6 and Figure 7 , each pair of limiting covers 5 can be detachably assembled to the first guide rail 16 of the corresponding pair of guide rail groups 13. Each of the limiting covers 5 includes a cover body 51 and two hooks 52. The cover body 51 defines a limiting groove 511 for accommodating the corresponding roller 344, and two side grooves 512 respectively connected to the two opposite sides of the limiting groove 511. Each of the side grooves 512 is elongated and its length extends along the first horizontal direction X, for the corresponding pivot rod 343 to pass through. The hooks 52 are arranged at one end of the cover body 51 in the opposite direction of the vertical direction Z and are spaced apart. Each of the hooks 52 is used to snap into the corresponding slot 19 of the corresponding rail 18, so that the limiting cover 5 can be fixed to the corresponding first guide rail 16 to receive the roller 344 moved out of the first guide rail 16. Each of the hooks 52 can be moved to bend and deform relative to the cover body 51, thereby disengaging from the corresponding slot 19 to release the latched state, allowing the limiting cover 5 to be removed from the corresponding first guide rail 16. With each of the hooks 52 being able to be released from the latched state and latched in the corresponding slot 19, each limiting cover 5 can be removably assembled to the corresponding first guide rail 16. Since each limiting cover 5 can be assembled to or removed from the corresponding first guide rail 16 without the aid of additional tools, the convenience of assembly and disassembly is effectively improved.

[0050] See Figure 3 、 Figure 8 and Figure 9 Each of the carrying brackets 3 can be in a horizontal position (such as Figure 8 As shown), and an upright state in which the corresponding opening 15 is exposed (as shown Figure 12 (as shown). In the lateral state, the supporting plate 31 is horizontal, and the roller 344 of each sliding mechanism 32 is slidably connected to the first guide rail 16 of the corresponding guide rail group 13, and the slider portion 334 is slidably connected to the second guide rail 17 of the corresponding guide rail group 13. In the first embodiment, the roller 344 is respectively located at the first angular position and the second angular position as an example, so that the roller 344 is slidably connected to the first guide rail 16 of the guide rail group 13 one above and one below. Of course, in other implementations of the first embodiment, the roller 344 can also be at the first angular position or the second angular position at the same time, so that the roller 344 is slidably connected to the same first guide rail 16, and is not limited to the above-mentioned manner.

[0051] When each of the supporting brackets 3 is in the horizontal state and the assembly and configuration of the electrical components are completed, each of the shock absorbers 4 can be assembled to the corresponding pair of guide rails 13. First, each of the shock absorbers 4 is moved along the first horizontal direction X so that the hook 418 of each of the buckle groups 417 passes through the corresponding opening 15 and penetrates into the corresponding first guide rail 16. Subsequently, the end surface 314 of the supporting plate 31 will extend into the cross frame body 411. The corresponding buffer components 42 arranged on the bottom plate 413 and the top plate 414 are respectively squeezed by the bottom surface 311 and the supporting top surface 312 to deform and accumulate elastic force, and slide on the bottom surface 311 and the supporting top surface 312 respectively. When each of the vertical rods 416 abuts against the corresponding end surface of the first guide rail 16, it will be blocked by it and cannot move further, thus completing the assembly of each of the shock absorbers 4. At this point, each hook 418 engages with the corresponding slot 19, and the corresponding buffer assembly 42 disposed on the end plate 415 is squeezed by the corresponding end surface 314, deforming and accumulating elastic force. With the slightly deformed buffer assembly 42 abutting against the bottom surface 311, the top support surface 312, and the corresponding end surface 314, the buffer assembly 42 is elastically clamped to the support plate 31. This allows each pair of shock absorbers 4 to be elastically clamped to the opposite ends of the corresponding support plate 31, securely holding the support plate 31.

[0052] Afterwards, each of the plates 21 (such as Figure 1 shown) by Figure 2 The open position shown is rotated to Figure 1 As shown in the closed position, the electrical components carried by each of the support brackets 3 can be driven to operate. Since the buffer components 42 of each pair of shock absorbers 4 are elastically clamped to the support plate 31, external vibrations such as those caused by earthquakes, human collisions, or road bumps during transportation are transmitted to the chassis 100 (e.g. Figure 1 (as shown), the support plate 31 of each support bracket 3 compresses the buffer assembly 42. The buffer assembly 42 deforms when subjected to force, absorbing the pressure transmitted by the support plate 31 and achieving a vibration-reducing effect. This prevents the electrical components supported by the support plate 31 from vibrating violently or slipping, minimizing the risk of vibration causing the connected transmission lines to become disconnected or causing malfunctions during operation.

[0053] See Figure 1 、 Figure 2 and Figure 3By designing the opening 15 of the housing 1 and the door panels 2, an operator can selectively open the panel 21 of any door panel 2 as needed, and then selectively remove or reattach each carrier bracket 3 through the corresponding opening 15 to the corresponding guide rail assembly 13 for replacement or expansion. This allows the chassis 100 to have greater flexibility in limited space.

[0054] For example, when the operator learns that a certain electrical component carried by a certain supporting bracket 3 has failed, the operator will detach one of the corresponding pairs of shock absorbers 4 from the corresponding pair of guide rail groups 13, and then pull the supporting bracket 3 to move it away from the corresponding pair of guide rail groups 13 through the corresponding opening 15. Then, the spare supporting bracket 3 is assembled back into the corresponding pair of guide rail groups 13 through the corresponding opening 15, and the chassis 100 can be restored to normal operation. If the operator is not sure which electrical component carried by the supporting bracket 3 has failed, the supporting bracket 3 of each layer can be replaced one by one, thereby quickly narrowing the area of ​​the failure. When the supporting bracket 3 carrying the failed electrical component is replaced, the chassis 100 can be restored to normal operation. By restoring the chassis 100 to normal operation first and then having the faulty electrical components inspected and repaired by a maintenance unit, the troubleshooting time can be greatly reduced, thereby minimizing the impact on the production line's productivity.

[0055] When it is desired to expand other new electrical components in the chassis 100, the support bracket 3 carrying the new electrical components is assembled to the empty pair of guide rails 13, or one of the support brackets 3 is replaced, and the expansion operation is completed. In this way, the chassis 100 has great flexibility in subsequent expandability, and the operation is very simple and convenient. When it is desired to update a certain electrical component carried by a certain support bracket 3 to have a new application function, the support bracket 3 is first moved away from the corresponding pair of guide rails 13, and then the support bracket 3 carrying the electrical component with the updated application function is assembled back to the corresponding pair of guide rails 13, and the operation of updating the application function of the electrical component is completed, which is very simple and convenient to operate.

[0056] See Figure 6 and Figure 10If there is no spare support bracket 3 to replace the support bracket 3 to be replaced and the electrical component carried by the support bracket 3 needs to be inspected on-site for troubleshooting, one of the corresponding pair of shock absorbers 4 is removed from the corresponding pair of guide rail assemblies 13, and then one of the pair of limiting covers 5 is assembled to the corresponding first guide rail 16 of the corresponding pair of guide rail assemblies 13. In this first embodiment, the pair of limiting covers 5 is assembled at the end of the first guide rail 16 located at the top of the pair of guide rail assemblies 13 away from the roller 344 located at the second angular position, but the present invention is not limited thereto. Of course, the pair of limiting covers 5 can also be assembled at the end of the first guide rail 16 located at the bottom of the pair of guide rail assemblies 13 away from the roller 344 located at the first angular position.

[0057] See Figure 10 、 Figure 11 and Figure 12 The supporting bracket 3 is pulled toward the pair of limiting covers 5, so that the roller 344 of each sliding mechanism 32 at the first angular position first moves away from the corresponding first guide rail 16. Subsequently, the roller 344 of each sliding mechanism 32 at the second angular position moves away from the corresponding first guide rail 16 and moves into the limiting groove 511 of the corresponding limiting cover 5. After moving into the limiting groove 511, the roller 344 is limited by the cover body 51 of the corresponding limiting cover 5 and cannot move further.

[0058] Then, the supporting bracket 3 is rotated along a first rotation direction R1, so that the corresponding pivot rod 343 of each sliding mechanism 32 rotates around the pivot shaft 342 (eg, Figure 4 By adjusting the corresponding telescopic rod 332 of each sliding mechanism 32 to adjust the position of the roller 344 at the first angular position, the roller 344 can match the height of the corresponding first guide rail 16 at an appropriate height position and can pass into the first guide rail 16.

[0059] When the fixed rod 331 of each sliding mechanism 32 abuts against the corresponding end surface of the first guide rail 16, it will be blocked and cannot continue to rotate. Figure 12The upright state shown. At this time, the supporting plate 31 is upright and located outside the opening 15, with the supporting top surface 312 facing outward. The roller groups 34 of each sliding mechanism 32 are spaced apart up and down along the vertical direction Z, and the pivot rod 343 of the roller group 34 located above extends along the vertical direction Z and the roller 344 is accommodated in the corresponding limiting groove 511 of the limiting cover 5. The pivot rod 343 of the roller group 34 located below extends along the first horizontal direction X, and the roller 344 is at the first angular position and connected to the corresponding first guide rail 16 of the corresponding guide rail group 13. In this way, the operator can easily inspect, repair or replace the electrical components on the supporting top surface 312.

[0060] During the above-mentioned detection process, the electrical components carried by the supporting brackets 3 of other layers need to be powered on and operated, and each supporting bracket 3 is connected to the corresponding pair of shock absorbers 4 (such as Figure 6 As shown in the figure, the supporting brackets 3 of the other layers can be firmly clamped to prevent them from sliding out of the corresponding pair of guide rail sets 13 through the corresponding openings 15 due to human accidental touch or collision.

[0061] When the fault is eliminated, the support bracket 3 is rotated along a second rotation direction R2 opposite to the first rotation direction R1, so that the corresponding pivot rod 343 of each sliding mechanism 32 rotates around the pivot shaft 342 (such as Figure 4 As shown) rotate, and the roller 344 at the first angular position moves away from the corresponding first guide rail 16. The roller 344 at the first angular position is adjusted back to the initial position by adjusting the corresponding telescopic rod 332 of each sliding mechanism 32. After the supporting bracket 3 rotates about 90 degrees, the supporting bracket 3 is pushed into the accommodating space 14, so that the roller 344 in the limiting cover 5 moves away from the limiting groove 511 and moves into the corresponding first guide rail 16, and the roller 344 at the first angular position moves into the corresponding first guide rail 16. When the supporting bracket 3 slides to Figure 8 In the position shown, one end of the carrier plate 31 is clamped by the undetached shock absorber 4. Finally, the disassembled shock absorber 4 is reassembled back into the corresponding pair of guide rails 13 to clamp the other end of the carrier plate 31, so that the carrier bracket 3 can be repositioned in the horizontal position.

[0062] See Figure 3 、 Figure 8 and Figure 12By arranging the supporting brackets 3 at intervals along the vertical direction Z, the accommodating space 14 can be fully and effectively utilized, so that a large number of the electrical components can be accommodated in the accommodating space 14. Since each supporting bracket 3 can be transformed between the horizontal state and the upright state, when it is necessary to perform on-site inspection, repair, or replacement of the electrical components on one of the supporting brackets 3, the supporting bracket 3 is transformed from the horizontal state to the upright state, so that the supporting plate 31 of the supporting bracket 3 is moved away from the accommodating space 14 and positioned outside the opening 15. This increases the convenience for operators to perform inspection, repair, or replacement.

[0063] It should be noted that the carrying bracket 3 of the first embodiment may also have the following different implementations in the upright state:

[0064] See Figure 13 In one embodiment, the pivot rod 343 of the roller assembly 34 located below each of the sliding mechanisms 32 extends along the vertical direction Z and the roller 344 can abut against the ground.

[0065] See Figure 14 Another embodiment is to omit the limit cover 5 (such as Figure 12 First, the supporting bracket 3 is moved away from the corresponding pair of guide rails 13, and the roller 344 of each sliding mechanism 32 at the second angle position is rotated to the first angle position. Then, the supporting bracket 3 is rotated 90 degrees and assembled back into the box 1, so that the pivot rod 343 of the upper roller group 34 extends along the first horizontal direction X, and the roller 344 is at the first angle position and connected to the corresponding first guide rail 16 of the corresponding guide rail group 13, and the roller group 34 at the lower position is connected to the first guide rail 16. Figure 12 The same assembly method is used to connect the roller 344 to the corresponding first guide rail 16 of the corresponding guide rail set 13 .

[0066] See Figure 2 and Figure 3 The chassis 100 of the first embodiment may also have the following different implementations according to needs:

[0067] One embodiment is that the number of the openings 15 and the number of the door panels 2 in the chassis 100 are each one, and one of the shock absorbers 4 in each pair of shock absorbers 4 can be detachably assembled to the corresponding pair of guide rail groups 13 and corresponds to the opening 15 and the door panel 2, and the other shock absorber 4 is configured to be fixed to the corresponding pair of guide rail groups 13.

[0068] In another embodiment, the number of the openings 15 of the chassis 100 and the number of the door panels 2 are each one, and the shock absorber 4 is omitted.

[0069] In another embodiment, the chassis 100 omits the vibration absorber 4 .

[0070] See Figure 15 and Figure 16 The overall structure of the second embodiment of the chassis 100 of the present invention is substantially the same as that of the first embodiment, except for the structure of each of the buffer components 42 .

[0071] In this second embodiment, each of the buffer components 42 includes a buffer bar 421 made of an elastic material for abutting against the bottom surface 311, the load-bearing top surface 312 or the corresponding end surface 314, and a plurality of springs 422 arranged between the cross frame 411 of the frame 41 and the buffer bar 421. The elastic material is, for example, polyvinyl chloride (PVC) or polyurethane (PU), but is not limited thereto. The buffer bar 421 is in the shape of an elongated strip and its length extends along the second horizontal direction Y. The springs 422 are arranged at intervals along the second horizontal direction Y. Each of the springs 422 is a compression spring, one end of which is fixed to the inner surface of the bottom plate 413, the inner surface of the top plate 414 or the inner surface of the end plate 415 by, for example, adhesive bonding or welding, and the other end is fixed to the corresponding buffer bar 421 by, for example, adhesive bonding.

[0072] When external vibration is transmitted to the chassis 100 (such as Figure 2 As shown), each of the carrying brackets 3 (as shown Figure 2 The supporting plate 31 (shown in FIG. 1 ) compresses the buffer strips 421, and each buffer strip 421 compresses the springs 422. When the springs 422 are subjected to force, they deform and absorb the pressure transmitted by the supporting plate 31, thereby achieving a vibration reduction effect.

[0073] In summary, the chassis 100 of each embodiment, by virtue of the sliding mechanism 32 of each support bracket 3 being slidably connected to the corresponding pair of guide rails 13 and each support bracket 3 being removable or reattached to the corresponding pair of guide rails 13 through the corresponding opening 15, allows for convenient and rapid replacement or expansion of the support brackets 3. This significantly reduces troubleshooting time, thereby minimizing the impact on production line productivity. By arranging the support brackets 3 at intervals along the vertical direction Z, the storage space 14 is fully and effectively utilized, allowing the storage space 14 to accommodate a large number of electrical components. The design of the opening 15 and door panel 2 of the housing 1 provides the chassis 100 with greater flexibility in limited space. By virtue of the fact that each support bracket 3 can be shifted between the horizontal and upright positions, it increases operator convenience during on-site inspection, repair, or replacement, effectively achieving the objectives of the present invention.
