In order to improve the efficiency, safety and maintainability of the power system, corresponding core devices such as semiconductor power devices and battery blocks need to be modularly packaged to form standardized and universal power modules.

[0003] As the power demand grows, the size and weight of power modules increase accordingly. In cabinets such as feeder cabinets, energy storage cabinets, and converter cabinets, it is often difficult to place or remove large-volume and heavy-weight power modules. This causes inconvenience in the installation and maintenance of power modules in complete sets of equipment, which urgently needs to be improved. Utility Model Content

[0004] In view of the defects or improvement needs of the prior art, the present application provides a support structure for a power module, aiming to improve the problem of inconvenience in installation and maintenance of the power module in a complete set of equipment.

[0005] The present application provides a support structure for a power module, comprising:

[0009] The above technical scheme conceived by the present application is compared with the prior art. Since the support frame can guide the power module and the pulley can provide rolling support for the power module, when the power module needs to be installed or maintained, it is only necessary to apply a certain push-pull force and slide the power module in and out along the inlet and outlet of the guide channel to quickly take and place the power module. This makes the installation and maintenance of the power module in the complete set of equipment more convenient, making the present structure particularly suitable for small spaces, large-capacity sites, and complete sets of equipment with maintenance time requirements.

[0010] As a further preference, the support frame includes a main board and a plurality of limit plates; the plurality of limit plates are connected to the upper end of the main board and surround the guide channel.

[0011] As a further preference, the support frame further comprises a support plate arranged at the inlet and outlet of the guide channel for supporting the power module.

[0012] As a further preference, the upper end of the support plate is bent to form a flange for supporting the power module.

[0013] As a further preferred embodiment, the upper end of the flange has a mounting groove, a folding rod is adjustably arranged in the mounting groove, the folding rod has a straight state and a bent state, and the flange has an adjuster for adjusting the state of the folding rod;

[0014] In the straight state, the folding rod does not protrude from the upper end surface of the flange, so that the power module can smoothly enter and exit the guide channel;

[0015] In the bent state, the folding rod protrudes from the upper end surface of the flange, so that the power module is confined in the guide channel.

[0016] As a further preference, a limiting cavity for limiting the range of movement of the mounting bracket is formed between the support plate and the limiting plate.

[0017] As a further preference, the mounting frame encloses a mounting cavity for mounting the pulley.

[0018] As a further preference, the pulley is detachably connected to the mounting frame.

[0019] As a further preference, a fastener for detachably connecting the mounting bracket and the supporting frame is provided between the mounting bracket and the supporting frame.

[0020] As further preferred, the fasteners include screws connecting the mounting bracket and the supporting frame.

[0021] In general, the above technical solutions conceived by this application have the following technical advantages compared with the prior art:

[0022] 1. The support frame can guide the power module, and the pulley can provide rolling support for the power module. When the power module needs to be installed or maintained, it is only necessary to slide and push the power module along the inlet and outlet of the guide channel to quickly take and place the power module, making the installation and maintenance of the power module in the complete set of equipment more convenient.

[0023] 2. The pulley is detachably connected to the mounting frame, and the mounting frame is detachably connected to the support frame, which is beneficial for the staff to increase or decrease the number of sliders and mounting frames according to the capacity and dimensions of the power module, so as to ensure the load-bearing and installation safety of the power module.

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a support structure for a power module. Figure 1-2 The support structure for the power module includes a support frame 1, a mounting frame 2 and a pulley 3. The support frame 1 has a guide channel 5 for guiding the power module 4. The mounting frame 2 is detachably provided with a plurality of pulleys 3. The mounting frame 2 is rotatably provided with a plurality of pulleys 3, and the rotation axis thereof is perpendicular to the guiding direction of the support frame 1. When the power module 4 enters and exits the support frame 1 along the guide channel 5, the pulley 3 rolls and fits with the power module 4.

[0034] Furthermore, the support frame 1 includes a main board 1-1, a limiting plate 1-2 and a supporting plate 1-3. A plurality of limiting plates 1-2 are provided, and the plurality of limiting plates 1-2 are connected to the upper end of the main board 1-1 and surround a guide channel 5. The supporting plate 1-3 is also connected to the upper end of the main board 1-1 and is located at the inlet and outlet of the guide channel 5. The supporting plate 1-3 is used to support the power module 4 to facilitate the installation of the power module 4.

[0035] In order to improve the supporting effect of the supporting plate 1 - 3 , the upper end of the supporting plate 1 - 3 is bent to form a horizontal flange 1 - 4 , and the flange 1 - 4 can provide a larger supporting area for the installation and removal process of the power module 4 .

[0036] In this embodiment, three limiting plates 1-2 are provided and one supporting plate 1-3 is provided. The three limiting plates 1-2 and the supporting plate 1-3 form a rectangular limiting cavity on the main board 1-1. The inner wall of the limiting cavity can limit the mounting frame 2 to limit the range of movement of the mounting frame 2.

[0037] In addition, the top surface height of the support plate 1-3 is lower than the top surface height of the limiting plate 1-2, wherein the two limiting plates 1-2 are parallel to each other and can enclose a guide channel 5 for guiding and limiting the power module 4, and the remaining limiting plate 1-2 is located at the end of the guide channel 5 and can block and limit the power module 4. In other embodiments, the number of limiting plates 1-2 can also be set to other numbers according to actual conditions.

[0038] Further, such as Figure 3-4 As shown, both ends of the mounting frame 2 in the length direction abut against the inner wall of the supporting frame 1 , and a fastener 6 for detachably connecting the mounting frame 2 and the supporting frame 1 is provided between the mounting frame 2 and the supporting frame 1 .

[0039] In this embodiment, the fastener 6 is selected as a screw, and threaded holes for installing the screws are reserved on the mounting frame 2 and the supporting frame 1. The mounting frame 2 and the supporting frame 1 are connected by screws, which is low-cost and easy to assemble.

[0040] In other embodiments, the fastener 6 may also be selected to be a buckle, a latch, a snap ring, etc., as long as it can achieve a detachable connection between the mounting bracket 2 and the supporting frame 1 .

[0041] Further, such as Figure 3 As shown, the mounting frame 2 is surrounded by a mounting cavity 2 - 1 for mounting the pulley 3 . The pulley 3 is detachably connected to the mounting frame 2 by screws, and the top of the pulley 3 is higher than the top surface of the mounting frame 2 and lower than the top surface of the supporting frame 1 .

[0042] Preferably, the support frame 1 and the mounting frame 2 in this embodiment are both made of cold-rolled steel plates or galvanized steel plates. In other embodiments, the support frame 1 and the mounting frame 2 can also be made of multiple plates assembled or welded.

[0043] During assembly, the pulley 3 is first installed into the mounting frame 2 by screws, and then the mounting frame 2 with the pulley 3 is placed into the support frame 1, and fastened by mounting screws to complete the assembly. Since the various parts of the support structure are modularly designed and the cost of each accessory is low, the installation process of the support structure is simple and convenient, reducing the difficulty of its own installation and production cost.

[0044] In addition, when using the support structure, the support structure can be installed inside the feed cabinet, energy storage cabinet, converter cabinet, etc. When the power module needs to be replaced or repaired, the door of the feed cabinet, energy storage cabinet or converter cabinet is opened, the power module is pulled out by applying a little force, and then the pulled power module is guided to the small lift to start replacement and maintenance. This design makes the effect of the support structure particularly obvious in occasions where the equipment placement space and maintenance space are narrow, which is conducive to the installation and maintenance of the power module in the complete set of equipment.

[0045] like Figure 5 As shown, in some embodiments, in order to improve the stability of the power module 4 in the support frame 1, the upper end of the flange 1-4 has a mounting groove 1-5, and the inner side wall of the mounting groove 1-5 is provided with a slide groove 1-6. Preferably, the length direction of the mounting groove 1-5 and the slide groove 1-6 is perpendicular to the guide direction of the guide channel 5. In addition, an adjustable folding rod 7 is provided in the mounting groove 1-5. The flange 1-4 has an adjuster in the mounting groove 1-5 for adjusting the state of the folding rod 7.

[0046] Specifically, the folding rod 7 includes two connecting sections that are rotatably connected to each other. The ends of the two connecting sections that face away from each other have a sliding rod slidably installed in the sliding groove 1-6. Through the cooperation of the sliding rod and the sliding groove 1-6, the two connecting sections can be rotated and adjusted in the installation groove 1-5 to form a straight state and a bent state.

[0047] It should be noted that, when in a straight state, the folding rod 7 does not protrude from the upper end surface of the flange 1-4, so that the power module 4 can smoothly enter and exit the guide channel 5; when in a bent state, the folding rod 7 partially protrudes from the upper end surface of the flange 1-4, and the folding rod 7 can resist the power module 4 in the guide channel 5, so that the power module 4 is restricted in the guide channel 5.

[0048] In this embodiment, the regulator specifically includes a spring 8 and a push plate 9. The push plate 9 has a slide bar, and the slide bar can be assembled in the slide groove 1-6, so that the push plate 9 can be slidably installed in the installation groove 1-5 under the cooperation of the slide bar and the slide groove 1-6. One end of the spring 8 is connected to the inner wall of the slide groove 1-6, and the other end is connected to the push plate 9. The spring 8 pushes the push plate 9, so that the push plate 9 pushes the folding rod 7, so that the folding rod 7 is in a bent state under normal conditions.

[0049] When the folding rod 7 needs to be switched to a straight state, the user can push the push plate 9 to compress the spring 8 so that the push plate 9 no longer pushes the folding rod 7, and then the folding rod 7 returns to a straight state under gravity. In other embodiments, the adjuster is a device such as an electric push rod or a cylinder installed in the installation slot 1-5, and its movable end can push the folding rod 7 to make the folding rod 7 rotate and adjust.

[0050] Furthermore, the inner wall of the installation groove 1-5 is also provided with a branch groove 1-7 connected to the slide groove 1-6. When the push plate 9 is pushed to the branch groove 1-7, pressing the push plate 9 downward can push the push plate 9 and push the slide rod on the push plate 9 into the branch groove 1-7. The slide rod is limited by the inner wall of the branch groove 1-7, so that the push plate 9 can be in a static state. At this time, the push plate 9 no longer pushes the folding rod 7, so that the folding rod 7 can return to a straight state under gravity, which is convenient for the staff to slide the power module 4 in and out of the support structure.
