The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0040] Please combine the specific Figures 1 to 4 As shown, the present application provides a capacitor module, comprising:

[0041] The capacitor group unit 1 comprises a first capacitor 11 and a second capacitor 12;

[0042] The conductive bar assembly 2 comprises a positive conductive bar 21, a negative conductive bar 22, and an intermediate conductive bar 23. The positive conductive bar 21, the negative conductive bar 22, and the intermediate conductive bar 23 are stacked and arranged;

[0043] The positive conductive bar 21 , the negative conductive bar 22 and the middle conductive bar 23 are all electrically connected to the capacitor group unit 1 , and under the action of the middle conductive bar 23 , the first capacitor 11 and the second capacitor 12 are connected in series.

[0044] In this embodiment, the first capacitor 11 and the second capacitor 12 are preferably electrolytic capacitors. In the process of completing the capacitor module, the first central axis of the first capacitor 11 is parallel to the second central axis of the second capacitor 12, and the first capacitor 11 and the second capacitor 12 are arranged opposite to each other. Specifically, the capacitor module also includes a support positioning frame 3, the support positioning frame 3 includes an assembly top surface and a support side surface extending along the circumferential direction of the assembly top surface. When the first capacitor 11 and the second capacitor 12 of the capacitor group unit 1 are fixedly connected to the support positioning frame 3, the first central axis of the first capacitor 11 and the second central axis of the second capacitor 12 are both perpendicular to the assembly top surface of the support positioning frame 3.

[0045] Considering that the first capacitor 11 and the second capacitor 12 can be firmly mounted on the support and positioning frame 3, the inventor provides a preferred method: Figures 1 to 4 As shown, the first capacitor body 11 is threadedly connected to the support and positioning frame 3 through the first fastener 41 , and the second capacitor body 12 is threadedly connected to the support and positioning frame 3 through the second fastener 42 .

[0046] In some embodiments, the first fastener 41 and the second fastener 42 are both nuts, and a first threaded portion 115 is protruded from the first body 114 of the first capacitor body 11 along its first central axis, and a first threaded segment that is compatible with the first fastener 41 is formed on the first threaded portion 115. A second threaded portion 125 is protruded from the second body 124 of the second capacitor body 12 along its second central axis, and a second threaded segment that is compatible with the second fastener 42 is formed on the second threaded portion 125. The assembly top surface and supporting side surface of the above-mentioned support and positioning frame 3 are enclosed to form an assembly accommodating cavity, and the first workstation hole 31 and the second workstation hole 32 are provided on the assembly top surface. Then, the first screw connection portion 115 of the first capacitor body 11 is moved toward the first workstation hole 31 and placed until the first screw connection portion 115 of the first capacitor body 11 passes through the first workstation hole 31. The first fastener 41 is threadedly connected to the first screw connection portion 115 from the assembly top surface toward one side of the assembly accommodating cavity, thereby achieving the purpose of detachable installation of the first capacitor body 11, so as to facilitate subsequent replacement and maintenance. In addition, the first fastener 41 is located in the assembly accommodating cavity, which can prevent the first fastener 41 from protruding outside the support and positioning frame 3, thereby ensuring that the support and positioning frame 3 and external components (such as the capacitor housing) are compactly and firmly installed. Similarly, the second threaded portion 125 of the second capacitor body 12 is moved toward the second work position hole 32 until the second threaded portion 125 of the second capacitor body 12 passes through the second work position hole 32. The second fastener 42 is threadedly connected to the second threaded portion 125 from the assembly top surface toward the side of the assembly accommodating cavity, thereby achieving the purpose of removable installation of the second capacitor body 12 to facilitate subsequent replacement and maintenance. At this time, the second fastener 42 is also located in the assembly accommodating cavity, and the second fastener 42 is prevented from protruding outside the support and positioning frame 3, thereby ensuring that the support and positioning frame 3 and external components (such as the capacitor housing) are compactly and securely installed.

[0047] In other embodiments, the first fastener 41 and the second fastener 42 are both bolts, and a first boss is formed on the first body 114 of the first capacitor body 11 along its first central axis, and a first threaded hole is formed on the first boss to match the first fastener 41. A second boss is formed on the second body 124 of the second capacitor body 12 along its second central axis, and a second threaded hole is formed on the second boss to match the second fastener 42. In this way, the first boss of the first capacitor body 11 is moved toward the first work position hole 31 and placed, and the first fastener 41 passes through the first work position hole 31 from the assembly top surface toward the side of the assembly accommodating cavity and is threadedly connected to the first threaded hole, similarly achieving the purpose of detachable installation of the first capacitor body 11. Similarly, the second boss of the second capacitor body 12 is moved toward the second work position hole 32 and placed, and the second fastener 42 passes through the second work position hole 32 from the assembly top surface toward the side of the assembly accommodating cavity and is threadedly connected to the second threaded hole, similarly achieving the purpose of detachable installation of the second capacitor body 12.

[0048] It should be noted that either of the above two embodiments can be used, or both embodiments can be used in combination. Of course, other fixed capacitor methods in existing capacitor modules can be used as conventional replacements for the above two embodiments, and the above two embodiments can also be used in combination with other fixed capacitor methods in existing capacitor modules.

[0049] It should also be noted that the first fastener 41 and the second fastener 42 are both made of non-metallic materials, such as nylon, to ensure that the capacitor module has good insulation and safety.

[0050] Further, please refer to Figures 1 to 5 As shown, the capacitor module includes multiple capacitor group units 1 as mentioned above, and the extension direction of the long side along the assembly top surface is defined as the length direction of the support positioning frame 3. Multiple capacitor group units 1 are arranged and distributed along the length direction of the support positioning frame 3, and each capacitor group unit 1 is installed and fixed on the support positioning frame 3. Multiple capacitor group units 1 are connected in series and parallel through the conductive bar assembly 2.

[0051] Specifically, see Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The first capacitor 11 further includes a first positive electrode 112 and a first negative electrode 113 disposed on the first body 114, and the second capacitor 12 further includes a second positive electrode 122 and a second negative electrode 123 disposed on the second body 124. The first negative electrode 113 of the first capacitor 11 is electrically connected to the intermediate conductive bar 23, and the second positive electrode 122 of the second capacitor 12 is electrically connected to the intermediate conductive bar 23. In other words, the first capacitor 11 of each capacitor group unit 1 is connected in series with the corresponding second capacitor 12 via the intermediate conductive bar 23. This arrangement not only increases the voltage of each capacitor group unit 1, but also, assuming that the voltage of the first capacitor 11 and the voltage of the second capacitor 12 are both 400V, the voltage of the first capacitor 11 and the second capacitor 12 connected in series will be 800V.

[0052] At the same time, if Figure 2 、 Figure 3 and Figure 3 As shown, because the intermediate conductive bar 23 is integrally formed, it provides a more integrated structure, ensuring that the intermediate conductive bar 23 as a whole has good overall performance. More importantly, the multiple capacitor groups 1 are mounted and fixed on the support and positioning frame 3. Each capacitor group 1 can be connected in series using only one intermediate conductive bar 23, eliminating the need for each capacitor group 1 to be electrically connected to a separate intermediate conductive bar 23, greatly improving assembly efficiency and convenience.

[0053] Furthermore, the first positive electrode 112 of the first capacitor 11 is electrically connected to the positive conductive bar 21, and the second negative electrode 123 of the second capacitor 12 is electrically connected to the negative conductive bar 22. With this arrangement, the capacitor group unit 1 will be able to supply power to the outside through the cooperation of the positive conductive bar 21 and the negative conductive bar 22. That is, the positive conductive bar 21 has a positive electrode connection portion 211, which is used to electrically connect to an external positive wire, and the negative conductive bar 22 has a negative electrode connection portion 221, which is used to electrically connect to an external negative wire. The number of the positive electrode connection portion 211 and the negative electrode connection portion 221 can be configured as one, or multiple according to design requirements. In addition, since the positive conductive bar 21 and the negative conductive bar 22 are also integrally formed, it can be ensured that the positive conductive bar 21 and the negative conductive bar 22 have good comprehensive performance, and multiple capacitor group units 1 are connected in parallel through the positive conductive bar 21 and the negative conductive bar 22, thereby being able to collect and output the electrical energy of multiple capacitor group units 1, replacing the traditional PCB's restrictions on current and power, and achieving the purpose of high power density and fast charging and discharging.

[0054] The unexpected effect is that multiple capacitor bank units 1 are connected in series and parallel via the conductive bar assembly 2, avoiding the complex structure and assembly difficulties caused by the existing multiple busbars being connected in sections and intervals. Furthermore, the stacked arrangement of the positive conductive bar 21, negative conductive bar 22, and intermediate conductive bar 23 in the conductive bar assembly 2 makes the overall structure of the capacitor module more compact, further facilitating the improvement of the capacitor module's high power density.

[0055] It can be understood that the above-mentioned positive conductive bar 21, negative conductive bar 22 and intermediate conductive bar 23 are preferably copper bars, and the positive conductive bar 21, negative conductive bar 22 and intermediate conductive bar 23 can also be selected as aluminum bars, or the positive conductive bar 21, negative conductive bar 22 and intermediate conductive bar 23 can also be made of composite materials, or the positive conductive bar 21, negative conductive bar 22 and intermediate conductive bar 23 can also be any two of copper bars, aluminum bars and composite bars.

[0056] It is also understandable that, in the case of multiple capacitor groups 1, the first capacitor bodies 11 of two adjacent capacitor groups 1 can be staggered, that is, the multiple first capacitor bodies 11 are staggered along the length direction of the support and positioning frame 3. This arrangement can effectively reduce inductance and improve the quality of the output power waveform.

[0057] In some embodiments, please refer to Figures 1 to 4As shown, the above-mentioned first capacitor body 11 also includes a first electrode portion 111, and the first positive electrode 112 and the first negative electrode 113 of the first capacitor body 11 are both arranged in the first electrode portion 111. The above-mentioned second capacitor body 12 also includes a second electrode portion 121, and the second positive electrode 122 and the second negative electrode 123 of the second capacitor body 12 are both arranged in the second electrode portion 121. Then the above-mentioned positive conductive row 21, negative conductive row 22, and middle conductive row 23 layers are all located on the side of the first capacitor body 11 close to the first electrode portion 111.

[0058] This arrangement can greatly reduce the difficulty of assembling the capacitor module. That is, after first fixing the first capacitor body 11 and the second capacitor body 12 of the capacitor group unit 1 to the support and positioning frame 3, the positive conductive bar 21, the negative conductive bar 22, and the middle conductive bar 23 are stacked one by one on the first capacitor body 11 and the second capacitor body 12. This effectively improves the assembly efficiency of the capacitor module. In addition, the structure of the positive conductive bar 21, the negative conductive bar 22, and the middle conductive bar 23 is simplified, thereby greatly reducing the overall cost of the capacitor module.

[0059] It should be noted that the stacking order of the positive electrode conductive bar 21, the negative electrode conductive bar 22, and the middle conductive bar 23 can be adjusted according to the assembly experience or structural design requirements of those skilled in the art. Figure 2 and Figure 3 As shown, the negative conductive bar 22 is disposed between the positive conductive bar 21 and the middle conductive bar 23 .

[0060] In other embodiments, the first positive electrode 112 and the first negative electrode 113 are respectively disposed on opposite ends of the first body 114 of the first capacitor 11, and the second positive electrode 122 and the second negative electrode 123 are respectively disposed on opposite ends of the second body 124 of the second capacitor 12. The positive conductive bar 21 is located on a side of the first capacitor 11 close to the first positive electrode 112, and the negative conductive bar 22 is located on a side of the first capacitor 11 close to the first negative electrode 113. In this case, the middle conductive bar 23 is formed into a U-shaped structure, that is, the middle conductive bar 23 includes a middle main body section extending along the first central axis of the first capacitor 11, and a first electrode section and a second electrode section fixedly connected to both ends of the middle main body section. The first electrode section is used to electrically connect to the first negative electrode 113, and the second electrode section is used to electrically connect to the second positive electrode 122.

[0061] In order to avoid the risk of short circuit during the electrical connection between the conductive bar assembly 2 and the capacitor group unit 1, the inventors also provide a preferred method. Figure 2 and Figure 3As shown, the middle conductive bar 23 has a first avoidance opening 231, and the first avoidance opening 231 is larger than the first positive electrode 112, so that when the first positive electrode 112 passes through the first avoidance opening 231, the first positive electrode 112 is located within the coverage range of the first avoidance opening 231 in the direction of the first central axis of the first capacitor 11, and the edge positions of the first avoidance opening 231 form a safe distance from the first positive electrode 112, thereby avoiding the risk of short circuit between the first positive electrode 112 of the first capacitor 11 and the middle conductive bar 23.

[0062] Further, please refer to Figure 2 and Figure 3 As shown, a second avoidance opening 232 is also provided on the middle conductive bar 23, and the second avoidance opening 232 is larger than the second negative electrode 123, so that when the second negative electrode 123 passes through the second avoidance opening 232, the second negative electrode 123 is located within the coverage range in the direction of the second central axis of the second capacitor 12, and the edge positions of the second avoidance opening 232 form a safe distance from the second negative electrode 123, thereby avoiding the risk of short circuit between the second negative electrode 123 of the second capacitor 12 and the middle conductive bar 23.

[0063] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the positive conductive bar 21 has a positive avoidance area 212. In the direction of the first central axis of the first capacitor 11, the first negative electrode 113 is located within the coverage of the positive avoidance area 212, and a safety distance is formed between the edge position of the positive avoidance area 212 and the first negative electrode 113. In the direction of the second central axis of the second capacitor 12, the second positive electrode 122 and the second negative electrode 123 are both located within the coverage of the positive avoidance area 212. In this way, a safety distance is formed between the second positive electrode 122 and the second negative electrode 123 and the edge position of the positive avoidance area 212, thereby avoiding the risk of short circuit between the second capacitor 12 and the first negative electrode 113 of the first capacitor 11 and the positive conductive bar 21.

[0064] In some embodiments, please refer to Figure 2 and Figure 3As shown, the negative conductive bar 22 has a negative avoidance area 222. In the direction of the first central axis of the first capacitor 11, the first positive electrode 112 and the first negative electrode 113 are located within the coverage of the negative avoidance area 222. Then, a safety distance is formed between the first positive electrode 112 and the first negative electrode 113 and the edge position of the negative avoidance area 222. In the direction of the second central axis of the second capacitor 12, the second positive electrode 122 is located within the coverage of the negative avoidance area 222. Then, a safety distance is formed between the edge position of the negative avoidance area 222 and the second positive electrode 122, thereby avoiding the risk of short circuit between the second positive electrodes 122 of the first capacitor 11 and the second capacitor 12 and the negative conductive bar 22.

[0065] In order to ensure and improve the safety performance of the capacitor module, a first insulating member 51 is provided between the first capacitor body 11 and the support and positioning frame 3, and / or a second insulating member 52 is provided between the second capacitor body 12 and the support and positioning frame 3. The first insulating member 51 and the second insulating member 52 here can be plates made of plastic material, rubber material, silicone material or glass material, so as to effectively ensure good insulation between the capacitor group unit 1 and the support and positioning frame 3. Of course, the first insulating member 51 can also be a side of the first capacitor body 11 that is close to the support and positioning frame 3 and is coated with an insulating coating, and the second insulating member 52 can also be a side of the second capacitor body 12 that is close to the support and positioning frame 3 and is coated with an insulating coating. It can be understood that the support and positioning frame 3 can also be a rack made of plastic, thereby improving the insulation performance and safety performance between the capacitor group unit 1 and the support and positioning frame 3.

[0066] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the conductive bar assembly 2 further includes a first insulator 24 and a second insulator 25. An assembly gap is provided between adjacent positive conductive bars 21, negative conductive bars 22, and intermediate conductive bars 23. One of the assembly gaps is defined as a first gap, and the other as a second gap. The first insulator 24 is assembled within the first gap, and the second insulator 25 is assembled within the second gap. The first insulator 24 and the second insulator 25 can be made of plastic, rubber, silicone, or glass to ensure good insulation between the positive conductive bars 21, negative conductive bars 22, and intermediate conductive bars 23.

[0067] On the other hand, based on the structure and connection relationship of the above-mentioned capacitor module, the inventor also discloses an elevator control cabinet, including the above-mentioned capacitor module and a control cabinet body, and the capacitor module is installed in the installation cavity of the control cabinet body.

[0068] The above is an explanation of the capacitor module proposed in the embodiment of the present application. Since the elevator control cabinet proposed in the embodiment of the present application adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0069] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "up", "down", "left", "right", etc. indicate directions or positional relationships, they are based on the directions or positional relationships shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
