DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0049] In a vehicle, there are many application scenarios of relays. For example, a relay can be applied to a motor controller. For different vehicle models, the demand for relays in the motor controller can be different. Exemplarily, a motor controller of a first vehicle model needs a relay with a larger size, and a motor controller of a second vehicle model needs a relay with a smaller size. If a manufacturer wants to produce the first vehicle model, a relay with a larger size is needed, and a first mounting member matching the relay with a larger size is also needed. If the manufacturer wants to produce the second vehicle model, a relay with a smaller size is needed, and a second mounting member matching the relay with a smaller size is also needed. In order to match relays with different sizes, the first mounting member and the second mounting member need to be set to different sizes and structures. This makes the manufacturer need two sizes of mounting members, which is relatively high in cost.

[0050] Therefore, the present application provides a mounting member, which aims to enable relays with different sizes to be installed on the mounting member, and reduces the cost required by the manufacturer to produce the first vehicle model and the second vehicle model.

[0051] According to a first aspect of the present application, with reference to Figures 1 to 13The present disclosure provides a mounting member 200, the mounting member 200 comprising a plurality of mounting portions 800, the plurality of mounting portions 800 being configured to mount a relay 700 selectively, the plurality of mounting portions 800 being configured to mount a relay 700 having different sizes. In this way, the mounting member 200 has a high versatility, and a manufacturer can selectively mount a relay 700 having different sizes to the mounting member 200 according to actual needs, which allows the manufacturer to produce a first vehicle model and a second vehicle model without purchasing two mounting members 200, and the manufacturer can mount a relay 700 having different sizes to different mounting portions 800 of the same mounting member 200. This is beneficial to reduce the cost required by the manufacturer to produce the first vehicle model and the second vehicle model. In addition, this is also beneficial to reduce the pressure of the manufacturer on the inventory of the mounting member 200. It is worth mentioning that if the mounting member 200 is made by a mold, it is beneficial to at least reduce the cost of a set of molds for the manufacturer.

[0052] Optionally, in some embodiments, the plurality of mounting portions 800 comprises a first mounting portion 220 and a second mounting portion 230. The first mounting portion 220 is configured to mount a first relay 710, and the second mounting portion 230 is configured to mount a second relay 720. The first relay 710 and the second relay 720 are relays 700 having different sizes. In this way, the mounting member 200 has a high versatility, and a manufacturer can selectively mount a relay 700 having different sizes to the mounting member 200 according to actual needs, which allows the manufacturer to produce a first vehicle model and a second vehicle model without purchasing two mounting members 200, and the manufacturer can mount a relay 700 having different sizes to different mounting portions 800 of the same mounting member 200. This is beneficial to reduce the cost required by the manufacturer to produce the first vehicle model and the second vehicle model. In addition, this is also beneficial to reduce the pressure of the manufacturer on the inventory of the mounting member 200. It is worth mentioning that if the mounting member 200 is made by a mold, it is beneficial to at least reduce the cost of a set of molds for the manufacturer.

[0053] It is worth mentioning that the relay 700 can be a relay 700 having a complete housing, a relay 700 having an incomplete housing, or a relay 700 having no housing.

[0054] The relay 700 having a complete housing is usually provided with a wire harness extending out of the housing as an electrical connection for connecting with external circuits, and the relay 700 having an incomplete housing and the relay 700 having no housing are beneficial to save the wire harness. The relay 700 having an incomplete housing and the relay 700 having no housing can use a first conductive row exposed to the outside as an electrical connection for connecting with external circuits. It can be understood that the relay 700 having an incomplete housing and the relay 700 having no housing are beneficial to improve the integration of the motor controller.

[0055] For the relay 700 with an incomplete shell, the relay 700 can include a frame 730 and a relay main body 740, the frame 730 at least partially surrounds the relay main body 740. For the frame 730 partially surrounding the relay main body 740, the frame 730 is in the shape of an open loop, and the opening of the frame 730 can but is not limited to provide a first conductive row of the relay main body 740 to extend out. The material of the frame 730 can but is not limited to be metal.

[0056] Optionally, in some embodiments, the mounting member 200 further includes a mounting seat 210, the mounting seat 210 is provided with a mounting groove 211, and the first mounting portion 220 and the second mounting portion 230 are arranged in the mounting groove 211. It can be understood that the mounting groove 211 is used for placing the relay 700, and the first mounting portion 220 and the second mounting portion 230 are used for assembling the mounting groove 211 and the relay 700. The mounting groove 211 is beneficial to realize the light weight of the mounting member 200.

[0057] Optionally, in some embodiments, the first mounting portion 220 includes two first positioning portions 221 arranged in a first direction, and the two first positioning portions 221 are used for cooperating with the first relay 710. It can be understood that the first relay 710 is arranged between the two first positioning portions 221, and one first positioning portion 221 cooperates with one side of the first relay 710, and the other first positioning portion 221 cooperates with the other side of the first relay 710. In this way, the first mounting portion 220 provides the first relay 710 with positioning in the first direction.

[0058] Exemplarily, the surfaces of the first positioning portion 221 and the first relay 710 that cooperate with each other are both planes, which is beneficial to improve the positioning accuracy of the first positioning portion 221 positioning the first relay 710. The two first positioning portions 221 are also used for clamping the first relay 710, which makes the relative pose of the first positioning portion 221 and the first relay 710 not easy to change, and makes the position of the first relay 710 not easy to deviate.

[0059] Optionally, in some embodiments, in the first direction, the mounting groove 211 has two opposite first groove side walls 212, and one first groove side wall 212 corresponds to one first positioning portion 221. In this way, the first positioning portion 221 can improve the structural strength of the first groove side wall 212, and reduce the occurrence of large deformation of the first groove side wall 212. It can be understood that the first positioning portion 221 makes the structure of the first groove side wall 212 more stable, and the structure of the first groove side wall 212 more stable also makes the pose of the first positioning portion 221 in the mounting member 200 more stable, and can reduce the occurrence of positioning failure of the first positioning portion 221.

[0060] Exemplarily, the mounting member 200 is an injection molded member, the first slot side wall 212 has a large area, which makes the first slot side wall 212 have a certain deformation amount after the mounting member 200 is molded, and the positioning accuracy of the first slot side wall 212 for positioning the first relay 710 is low. The first positioning part 221 can be a protruding rib of the first slot side wall 212, the first positioning part 221 has a small volume and is less affected by the molding of the mounting member 200 as an injection molded member, that is, the surface of the first positioning part 221 for cooperating with the first relay 710 can have a small deformation amount after the molding of the mounting member 200. This makes the first positioning part 221 have high accuracy for positioning the first relay 710.

[0061] However, the design is not limited to this, and in some other embodiments, the first positioning part 221 is arranged on the slot bottom wall of the mounting slot 211, and the first positioning part 221 is arranged spaced apart from the slot side wall of the mounting slot 211.

[0062] Optionally, in some embodiments, the first positioning part 221 has a first side opposite to another first positioning part 221, and the first side includes, in sequence from the slot opening of the mounting slot 211 to the slot bottom of the mounting slot 211, a guide surface 222 and a positioning surface 223, the distance between the two guide surfaces 222 gradually decreases from the slot opening of the mounting slot 211 to the slot bottom of the mounting slot 211, and the two positioning surfaces 223 are used for positioning cooperation with the first relay 710. In this way, the first relay 710 can slide on the guide surfaces 222 from the slot opening of the mounting slot 211 to the slot bottom of the mounting slot 211, and is positioned and cooperated with the two positioning surfaces 223 under the guidance of the guide surfaces 222. This is conducive to reducing the difficulty of positioning cooperation between the first relay 710 and the first positioning part 221.

[0063] Optionally, in some embodiments, the second mounting part 230 includes two second positioning parts 231 spaced apart along the first direction, the two second positioning parts 231 are used for inserting the second relay 720, and the sides of the two second positioning parts 231 facing away from each other are used for positioning cooperation with the second relay 720. In this way, the second mounting part 230 provides positioning of the second relay 720 in the first direction.

[0064] Exemplarily, the relay 700 includes a frame 730 and a relay main body 740, the second positioning part 231 cooperates with the opposite two inner side walls of the frame 730, and there is a space between the inner side walls of the frame 730 and the relay main body 740 for the second positioning part 231 to extend into.

[0065] Optionally, in some embodiments, the second positioning portion 231 is arranged on the bottom wall of the mounting groove 211, and the second positioning portion 231 has a first end close to the opening of the mounting groove 211 and a second side opposite to the other second positioning portion 231. The second positioning portion 231 is provided with an avoiding space 232 at the first end and the second side, and the avoiding space 232 is used for the extension of any one of the relays 700. In this way, the interference between the second positioning portion 231 and the relay 700 is reduced. For example, the avoiding space 232 is used for the extension of the relay body 740.

[0066] Optionally, in some embodiments, the mounting member 200 further comprises a positioning platform 240 arranged on the mounting groove 211, and the positioning platform 240 is arranged on one side of the mounting groove 211 close to the opening of the mounting groove 211 and used for positioning and matching with any one of the relays 700. In this way, the positioning platform 240 provides positioning in the depth direction of the mounting groove 211 for any one of the relays 700. In addition, it is worth mentioning that the outer circumferential surface of the mounting groove 211 and the inner circumferential surface of the mounting groove 211 limit a glue pouring cavity for pouring glue. This makes the glue connect the relays 700 and the groove wall of the mounting groove 211. When the mounting member 200 is applied to a vehicle, the vibration of the vehicle operation can cause the glue to reduce the amplitude of the relays 700 following the vibration of the vehicle. The positioning platform 240 can be arranged on the bottom wall of the mounting groove 211 or on the side wall of the mounting groove 211 so that the positioning platform 240 is arranged in a spaced manner with the bottom wall of the mounting groove 211.

[0067] Optionally, in some embodiments, the groove wall of the mounting groove 211 is provided with a first mounting hole 214 used for penetrating a fastener for connecting any one of the relays 700 and the mounting base 210. In this way, the relays 700 and the mounting member 200 are connected more stably.

[0068] Optionally, in some embodiments, the relay 700 has a first conductive row, and the mounting member 200 further comprises a second conductive row 250 arranged on the mounting base 210, and the fastener is used to sequentially connect the first conductive row, the second conductive row 250 and the mounting base 210. In this way, the fastener not only connects the relay 700 and the mounting member 200 together, but also electrically connects the first conductive row and the second conductive row 250.

[0069] Optionally, in some embodiments, the mounting member 200 comprises a mounting base 210 provided with a first mounting hole 214, and the relay 700 is provided with a second mounting hole, and the first mounting hole 214 and the second mounting hole are used for penetrating a fastener to connect the mounting base 210 and the relay 700 together. It can be understood that in the depth direction of the first mounting hole 214, the first mounting hole 214 and the second mounting hole are aligned, and then the fastener is penetrated into the first mounting hole 214 and the second mounting hole, which is more convenient.

[0070] The inventor finds that in the process of replacing the relay 700 with different size, more time is spent on setting the second mounting hole opposite to the first mounting hole 214 in the hole depth direction of the first mounting hole 214. For this purpose, the mounting member 200 further comprises a first mounting portion 220 for providing positioning for the first relay 710 in a first direction, a second mounting portion 230 for providing positioning for the second relay 720 in the first direction, a third mounting portion for providing positioning for the first relay 710 in a second direction, and a fourth mounting portion for providing positioning for the second relay 720 in the second direction. The first direction, the second direction and the hole depth direction of the first mounting hole 214 are different. The first relay 710 is positioned by cooperating with the first mounting portion 220 and the third mounting portion respectively, so that the second mounting hole is set opposite to the first mounting hole 214 in the hole depth direction of the first mounting hole 214. The second relay 720 is positioned by cooperating with the second mounting portion 230 and the third mounting portion respectively, so that the second mounting hole is set opposite to the first mounting hole 214 in the hole depth direction of the first mounting hole 214. It can be understood that no matter the first relay 710 or the second relay 720, the mounting member 200 can provide positioning so that the second mounting hole of the relay 700 is set opposite to the first mounting hole 214 in the hole depth direction of the first mounting hole 214. In this way, when replacing the relay 700 with different size, the time spent on setting the second mounting hole opposite to the first mounting hole 214 in the hole depth direction of the first mounting hole 214 is less, which is beneficial to improve the efficiency of the mounting member 200 in replacing the relay 700 with different size.

[0071] Furthermore, the mounting base 210 is provided with a mounting groove 211, which includes a first groove sidewall 212 and a second groove sidewall 213. The second groove sidewall 213 has a first mounting hole 214. When some relays 700 are placed in the mounting groove 211, there is a gap between the outer peripheral surface of these relays 700 and the groove sidewall of the mounting groove 211. The direction from one first groove sidewall 212 to the other groove sidewall is referred to as the first direction. This makes it easy for the second mounting hole to deviate from the first mounting hole 214 in the first direction, that is, it is difficult for the second mounting hole to be aligned with the first mounting hole 214. This results in a lower efficiency in fastener connection between the mounting base 210 and the relays 700. In addition, when some relays 700 are placed in the mounting groove 211, the second mounting hole of these relays 700 is easy to deviate from the first mounting hole 214 in the groove depth direction of the mounting groove 211, that is, it is difficult for the second mounting hole to be aligned with the first mounting hole 214. Therefore, the mounting component 200 needs to provide positioning for the relay 700 in both the first direction and the depth direction of the mounting groove 211, so that the second mounting hole can be aligned with the first mounting hole 214 in the depth direction of the first mounting hole 214. The mounting component 200 also includes a positioning platform 240 provided in the mounting groove 211. The side of the positioning platform 240 near the opening of the mounting groove 211 is used for positioning and engaging any of the relays 700 with different external dimensions. The third mounting part and the fourth mounting part are the same component, and the third mounting part is configured as the positioning platform 240. The second direction is the depth direction of the mounting groove 211. The first mounting part 220 includes two first positioning parts 221. The two first groove sidewalls 212 are provided with the first positioning parts 221. The side of the two first positioning parts 221 that are close to each other is used for positioning and engaging with the opposite sides of the first relay 710. The positioning platform 240 and the first mounting part 220 together align the second mounting hole of the first relay 710 with the first mounting hole 214 in the depth direction of the first mounting hole 214. The second mounting part 230 includes two second positioning parts 231, which are disposed on the bottom wall of the mounting groove 211. The opposite sides of the two second positioning parts 231 are used to cooperate with the second relay 720, and the two second positioning parts 231 are used to insert the second relay 720. The positioning platform 240 and the second mounting part 230 together align the second mounting hole of the second relay 720 with the first mounting hole 214 in the depth direction. The two first positioning parts 221 are positioned opposite each other and spaced apart in a first direction, and the two second positioning parts 231 are positioned opposite each other and spaced apart in a first direction, with the two second positioning parts 231 positioned between the two first positioning parts. When the second relay 720 is needed, it can be removed from the mounting member 200 and connected to the mounting member 200 using fasteners. When the first relay 710 is needed, it can be removed from the mounting member 200 and connected to the mounting member 200 using fasteners.Fasteners may be configured as bolts, but are not limited to.

[0072] Secondly, embodiments of this utility model provide a capacitor module 100, which includes a relay and the aforementioned mounting member 200. The capacitor module 100 employs all the technical solutions of all the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. The relay 700 is mounted on the mounting member 200.

[0073] Optionally, in some embodiments, the capacitor module 100 further includes a power distribution fuse disposed on the mounting member 200. This is beneficial for improving the integration of the capacitor module 100 and for shortening the wiring harness length.

[0074] Thirdly, embodiments of this utility model provide a motor controller, which includes the aforementioned capacitor module 100. The motor controller employs all the technical solutions of all the above embodiments, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0075] Optionally, in some embodiments, the motor controller further includes an IGBT module and a third busbar 400, the third busbar 400 connecting the IGBT module and the capacitor module 100. The relative positions of the IGBT module and the capacitor module 100 can be more flexible through the third busbar 400. For example, the IGBT module includes a first negative busbar 320 and a first positive busbar 310, and the capacitor module 100 includes a second negative busbar 290 and a second positive busbar 280. The third busbar 400 connects the first negative busbar 320 and the second negative busbar 290, or the third busbar 400 connects the first positive busbar 310 and the second positive busbar 280.

[0076] Optionally, in some embodiments, the IGBT module is provided with a positioning protrusion 330, and the third conductive bus 400 is provided with a positioning hole 410 that mates with the positioning protrusion 330. This helps to improve the assembly efficiency of the third conductive bus 400 and the IGBT module.

[0077] Optionally, in some embodiments, the third conductive bus 400 is provided with stress relief holes 420. The stress relief holes 420 can release the stress inside the third conductive bus 400, thus reducing the likelihood of warping of the third conductive bus 400. It is worth mentioning that the stress relief holes 420 can also serve as pre-welding inspection holes, used for positioning the laser in the laser equipment. Thus, the laser welding equipment can define the initial position of the laser through the pre-welding inspection holes. In one embodiment, two pre-welding inspection holes are provided.

[0078] Optionally, in some embodiments, the IGBT module further includes a first positive electrode bus 310, and the motor controller further includes an insulating layer 430, which is disposed on the side of the third electrode bus 400 near the first positive electrode bus 310. This reduces the possibility of a short circuit due to accidental contact between the third electrode bus 400 and the first positive electrode bus 310, thus improving the safety of the capacitor module 100.

[0079] Optionally, in some embodiments, the insulating layer 430 is made of a high-temperature resistant material. The high-temperature resistant insulating layer 430 makes the third conductive bus 400 less susceptible to melting under welding laser irradiation.

[0080] Optionally, in some embodiments, the motor controller further includes a housing and a thermal pad. The capacitor module 100 is housed in the housing, and the capacitor module 100 also includes a fourth conductive bus 270, which is connected to the housing via the thermal pad. The fourth conductive bus 270 generates heat during operation. This heat can be transferred from the fourth conductive bus 270 to the housing via the thermal pad, and then from the housing to the external environment. This prevents the temperature of the fourth conductive bus 270 from becoming too high, thereby preventing the temperature of the capacitor module 100 from becoming too high.

[0081] For example, the fourth conductive bus 270 passes through the mounting member 200, which makes the connection between the fourth conductive bus 270 and the mounting member 200 more secure. It is understood that the mounting member 200 at least partially covers the fourth conductive bus 270, which makes it easy for heat to accumulate on the fourth conductive bus 270, thus causing the temperature of the fourth conductive bus 270 to be relatively high. The fourth conductive bus 270 can reduce heat accumulation on the fourth conductive bus 270 through a thermal pad, thus preventing the temperature of the fourth conductive bus 270 from becoming too high, thereby preventing the temperature of the capacitor module 100 from becoming too high. The fourth conductive bus 270 may be used, but is not limited to, for connection with the relay 700.

[0082] Optionally, in some embodiments, the motor controller further includes an adapter circuit board 600, and the capacitor module 100 further includes a voltage sampling point 260. The adapter circuit board 600 is used to connect the voltage sampling point 260 and the relay 700. This helps to reduce the use of wiring harnesses and improves the automation level of motor controller manufacturing. The voltage sampling point 260 may be configured as a DC bus negative voltage sampling point 260 or a DC bus positive voltage sampling point 260, but is not limited to.
