Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of motor controller, especially relates to a wiring seat, motor controller assembly and vehicle. BACKGROUND

[0002] The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time by active work. In the electric vehicle, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required by the driving motor according to the gear, throttle, brake and other instructions, to control the starting operation, forward and backward speed, climbing force and other driving states of the electric vehicle, or to help the electric vehicle brake and store part of the brake energy in the power battery. In a word, the motor controller is one of the key components of the electric vehicle.

[0003] The wiring seat of the motor is used for connecting the motor controller and the three-phase terminal of the motor.

[0004] With the development of new energy technology, in order to save space, reduce cost and increase product reliability, the development of the motor controller tends to integrate more functions, such as integrating the high-voltage distribution box into the motor controller.

[0005] The motor controller integrated with the high-voltage distribution box will increase more than ten high-current high-voltage wire harness interfaces to fixedly connect the devices in the high-voltage distribution box with the external structure, so that the number of high-current high-voltage wire harness interfaces in the whole motor controller increases to 20-30. When the number of wire harness interfaces of the motor controller increases, the number of corresponding wire harness interfaces on the wiring seat will also increase.

However, with the increase of the wire harness interfaces, the size of the wiring seat in the direction will increase, which causes the size of the motor controller assembly in the direction to be too large, resulting in insufficient installation space of the whole vehicle.

[0039] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present utility model.

[0040] Hereinafter, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0041] The motor controller is an integrated circuit that controls the motor to work in the set direction, speed, angle, response time by active work. In electric vehicles, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required by the driving motor according to the gear, throttle, brake and other instructions, to control the starting operation, forward and backward speed, climbing force and other driving states of the electric vehicle, or to help the electric vehicle brake and store part of the brake energy in the power battery. In a word, the motor controller is one of the key components of the electric vehicle.

[0042] The terminal block of the motor is used for connecting the motor controller and the three-phase terminal of the motor.

[0043] With the development of new energy technology, in order to save space, reduce cost, increase product reliability, the development of motor controller tends to integrate more functions, for example, integrating high-voltage distribution box into motor controller.

[0044] The motor controller integrated with the high-voltage distribution box will increase more than ten high-voltage and large-current wire harness interfaces to fixedly connect the devices in the high-voltage distribution box with the external structure, so that the number of high-voltage and large-current wire harness interfaces in the entire motor controller increases to 20-30. When the number of wire harness interfaces of the motor controller increases, the number of corresponding wire harness interfaces on the terminal block will also increase.

[0045] Usually, the wire harness interfaces are arranged in sequence along a certain direction of the horizontal plane of the terminal block, so as to facilitate the arrangement and connection of the wire harness. However, with the increase of the wire harness interfaces, the size of the terminal block in the direction will increase, thereby causing the size of the motor controller in the direction to be too large, resulting in insufficient installation space of the whole vehicle.

[0046] Based on this, the application discloses a terminal block, which is arranged with multiple layers of wire harness interfaces in the height direction on the terminal block, thereby improving the wire outlet utilization rate of the terminal block and fundamentally solving the demand for multiple high-voltage and large-current wire outlets of the motor controller.

[0047] Specifically, in combination with Figures 1 to 5 the application, the terminal block comprises a terminal block body 1 and a conductive row (not shown in the figure). Among them, Figures 1 to 5 is a structural schematic diagram of the terminal block in different perspectives of the application.

[0048] Among them, the terminal block body 1 is an insulating part to prevent short circuit when the motor controller is connected with the motor three-phase terminal, and the terminal block body 1 is an example of an injection molded plastic or rubber part. The shape and size of the terminal block body 1 can be set according to different needs, which are not specifically limited here and are within the protection scope.

[0049] The terminal block body 1 comprises a first mounting surface 11 and a second mounting surface 12.

[0050] Among them, the plane of the first mounting surface 11 and the plane of the second mounting surface 12 are not coplanar. In some embodiments, the first mounting surface 11 and the second mounting surface 12 can be circumferentially adjacent surfaces of the terminal block body 1, or the first mounting surface 11 and the second mounting surface 12 are surfaces arranged in the height direction of the terminal block body 1.

[0051] The first mounting surface 11 and the second mounting surface 12 are both provided with wire harness interfaces 13, and the wire harness interfaces 13 on the first mounting surface 11 and the wire harness interfaces 13 on the second mounting surface 12 are arranged in the height direction of the terminal block body 1.

[0052] The first mounting surface 11 and the second mounting surface 12 are not coplanar, and the wire harness interfaces 13 on the first mounting surface 11 and the wire harness interfaces 13 on the second mounting surface 12 are arranged in staggered positions in the height direction, which facilitates the arrangement of the wire harnesses and prevents the influence between the wire harnesses.

[0053] The conductive bar in the present application is mounted on the terminal block body 1, and the conductive bar is a conductive member for electrically connecting the motor wire harness and the terminal of the motor controller. Exemplarily, the conductive bar includes but is not limited to a conductive copper bar.

[0054] In the present application, the wire harness interfaces 13 are arranged on different surfaces of the terminal block body 1, and the wire harness interfaces 13 are arranged in staggered positions in the height direction, that is, the terminal block body 1 is arranged in multiple layers in the height direction, which is beneficial to improve the wire outlet utilization rate of the terminal block body 1, and double wire harnesses can be arranged under the same terminal block length, greatly reducing the requirement for wiring space, reducing the size of the motor controller, and meeting the requirements of most customers for single-layer wire outlet, that is, it is beneficial to improve the internal space utilization of the motor controller and improve the power density of the product. In addition, compared with the way of increasing multiple wire harness interfaces 13 in the length direction, the way of arranging the wire harness interfaces 13 in multiple layers in the height direction of the terminal block body 1 is more beneficial to reduce the overall volume of the terminal block body 1 and reduce the weight of the motor controller with the terminal block, thereby meeting the requirements of product lightening and saving costs.

[0055] In some embodiments, the first mounting surface 11 and the second mounting surface 12 are arranged side by side in the first direction, and the first mounting surface 11 and the second mounting surface 12 are each provided with multiple wire harness interfaces 13 in the second direction. Specifically, the first mounting surface 11 and the second mounting surface 12 are arranged in parallel, and exemplarily, the first mounting surface 11 and the second mounting surface 12 can be opposite two side surfaces of the rectangular terminal block body 1. In the present application, the terminal block body 1 is a stepped surface, and the first mounting surface 11 and the second mounting surface 12 are different steps of the terminal block body 1.

[0056] It should be noted that the arrangement direction of the first mounting surface 11 and the second mounting surface 12 is the first direction, and the second direction is the length direction of the first mounting surface 11 and the second mounting surface 12, and multiple wire harness interfaces 13 are arranged along the direction. The number and spacing of the wire harness interfaces 13 can be set according to different needs, and are within the protection scope. The first direction and the second direction are both perpendicular to the height direction of the terminal block body 1.

[0057] The wire harness interfaces 13 of the first mounting surface 11 and the wire harness interfaces 13 of the second mounting surface 12 are arranged in staggered positions in the height direction, thereby realizing layering. Exemplarily, the first mounting surface 11 is arranged with only one layer of wire harness interfaces 13 in the height direction, and the second mounting surface 12 is arranged with only one layer of wire harness interfaces 13 in the height direction.

[0058] The terminal body 1 in the present application is a stepped structure in the height direction. For example, the terminal body 1 is divided into a first section and a second section in the height direction, and the second section is the top and the first section is the bottom. The first section is convex to the second section in the first direction. The first section forms the first mounting surface 11, and the second section forms the second mounting surface 12. The first mounting surface 11 is convex to the second mounting surface 12 in the first direction, so that the first mounting surface 11 and the second mounting surface 12 are arranged in the first direction to avoid affecting each other during the wiring harness assembly process.

[0059] In combination Figure 4 and Figure 5 As shown in the drawings, the terminal in the present application further includes a first conductive row positioning nut column 31 and a second conductive row positioning nut column 32.

[0060] It should be noted that in the present application, the terminal body 1 has two layers of wiring harness interfaces 13, and each layer of wiring harness interface 13 corresponds to one end of the conductive row. For example, the first end of the conductive row is connected to the first conductive row positioning nut column 31, and the second end of the conductive row is connected to the second conductive row positioning nut column 32. Optionally, the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32 correspond one-to-one, and are arranged one-to-one with the conductive row. For the number and arrangement of the conductive row of the wiring harness interface 13 of other layers, please refer to the following description.

[0061] The first conductive row positioning nut column 31 is installed on the first mounting surface 11 and used to position the first end of the conductive row. The first end of the conductive row is used to connect the wiring harness connected to the wiring harness interface 13 of the first mounting surface 11. The second conductive row positioning nut column 32 is installed on the second mounting surface 12 and used to position the second end of the conductive row. The second end of the conductive row is used to connect the wiring harness connected to the wiring harness interface 13 of the second mounting surface 12.

[0062] In the present application, the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32 can realize the installation of the conductive row. By providing the conductive row positioning nut column 3 (including the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32), when installing the outgoing copper row (including the first conductive row and the second conductive row), the outgoing conductive row is fixed to the conductive row positioning nut column 3 by screws. The outgoing conductive row includes but is not limited to copper row.

[0063] In some embodiments, the conductive row corresponds one-to-one to the wiring harness interface 13, the number of the first conductive row positioning nut column 31 corresponds one-to-one to the first end of the conductive row, and the number of the second conductive row positioning nut column 32 corresponds one-to-one to the second end of the conductive row. Or the number of the first conductive row positioning nut column 31 is less than the number of the first end of the conductive row, and the number of the second conductive row positioning nut column 32 is less than the number of the second end of the conductive row.

[0064] The number of the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32 can be set according to different needs, and are within the protection scope.

[0065] In optional embodiments, the first conductive row positioning nut column 31 and / or the second conductive row positioning nut column 32 are injection molded in the terminal block body 1. Specifically, the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32 are placed in advance in a mold for injection molding the terminal block body 1, so that the first conductive row positioning nut column 31 and the second conductive row positioning nut column 32 are injection molded in the terminal block body 1 during the injection molding of the terminal block body 1.

[0066] In the present application, the conductive row positioning nut column is injection molded on the terminal block body 1, solving the problem of deformation and tearing of the terminal block body 1 caused by excessive torque during the installation of the wire harness.

[0067] As shown in Figure 3 , the terminal block in the present application further comprises a hexagonal nut column 2.

[0068] The hexagonal nut column 2 is arranged at the wire harness interface 13, and it can be understood that the hexagonal nut column 2 forms the wire harness interface 13 and is used for connecting with the wire harness.

[0069] It should be noted that the nut column for wiring in the present application adopts a hexagonal nut column, which can increase the connection area of the hexagonal nut column 2 and the terminal block body 1, is conducive to the installation of the hexagonal nut column 2, and is conducive to improving the connection strength of the hexagonal nut column 2 and the terminal block body 1.

[0070] In some embodiments, the hexagonal nut column 2 is injection molded integrally with the terminal block body 1. Specifically, the hexagonal nut column 2 is placed in advance in a mold for injection molding the terminal block body 1, so that the hexagonal nut column 2 is injection molded in the terminal block body 1 during the injection molding of the terminal block body 1.

[0071] The nut column for wiring in the present application adopts a hexagonal nut column 2, and adopts an injection molding connection mode, which increases the anti-torsion ability of the hexagonal nut column 2 injection molded in the terminal block body 1, and fundamentally solves the problem of the nut column slipping and falling off from the terminal block body 1 during the installation of the wire harness.

[0072] Since the terminal block body 1 is a plastic or rubber part injection molded, it is easy to cause damage to the terminal block body 1 when it is assembled and connected with other parts. Based on this, the mounting seat 14 of the terminal block body 1 in the present application is embedded with a strength reinforcing part, wherein the strength of the strength reinforcing part is greater than the strength of the terminal block body 1.

[0073] It should be noted that the strength reinforcing member includes but is not limited to a metal member, and the connection mode of the strength reinforcing member to the mounting seat 14 of the terminal block body 1 includes but is not limited to bonding or injection molding.

[0074] Exemplarily, a steel sleeve is added in the mounting seat 14 of the terminal block body 1, so as to increase the strength of the mounting seat 14 of the terminal block body 1, solve the problem of rupture of the terminal block body 1 caused by large screw torque during installation of the conventional terminal block body 1 to the box, and effectively ensure the integrity of the terminal block body 1 while meeting the large torque installation.

[0075] In some embodiments, the steel sleeve is placed in the mold of the terminal block body 1 in advance, and the steel sleeve is embedded and injection molded into the terminal block body 1 during injection molding of the terminal block body 1.

[0076] As shown above, the terminal block body 1 of the terminal block in the application adopts a double-layer design, which improves the utilization rate of the internal space of the motor controller, increases the power density of the product, reduces the weight of the motor controller, meets the light weight requirement of the product, and saves the cost by reducing the volume; the conductive bar positioning nut column is injection molded on the terminal block body 1 to prevent the copper bar from deforming during wiring of the motor controller; the upper and lower interface surfaces are the wiring harness installation surfaces of the whole vehicle, and the OT terminals of the wiring harness are bolted to the corresponding positions during installation; due to the large installation torque, the hexagonal nut column 2 is molded into the terminal block body 1, which can increase the torsional resistance of the terminal block to 40 N·m.

[0077] In addition, the application protects a motor controller assembly including a terminal block and a motor controller, wherein the terminal block is the terminal block disclosed in the above embodiments, and therefore the motor controller assembly with the terminal block also has all the technical solutions described above. For the structure of the motor controller, please refer to the known motor controller.

[0079] In some embodiments, the high-voltage distribution box is integrated into the motor controller of the motor controller assembly, and for the specific functional parts of the high-voltage distribution box, please refer to the known high-voltage distribution box.
