Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle components, in particular to an adapter seat, an electric drive assembly and a vehicle. BACKGROUND

[0002] The copper bar connecting seat is widely used on the electric drive assembly of the vehicle, for connecting the motor controller and the drive motor, realizing the intercommunication of the motor controller and the drive motor, and transmitting the current. In order to transmit the current between the copper bar connecting seat and the motor controller, the connecting position of the copper bar connecting seat and the motor controller is usually made of metal. When the copper bar connecting seat and the motor controller are tightly connected, metal debris is generated due to the friction between the copper bar and the motor controller. Since the connecting position is close to the circuit board arranged in the motor controller, the metal debris falls on the circuit board, causing the short circuit of the circuit board and failure.

[0003] CN218005341U discloses a double electric control three-phase copper bar support seat, relating to the technical field of electric vehicle electric control connecting parts, comprising a support seat, a first three-phase copper bar and a second three-phase copper bar, the first three-phase copper bar and the second three-phase copper bar are integrally formed with the support seat by injection molding, a first mounting seat for mounting the support seat is fixedly arranged on one side of the support seat, a second mounting seat for mounting the support seat is fixedly arranged on the other side of the support seat, and a third mounting seat for mounting the support seat is fixedly arranged at one end of the support seat.

[0004] The above-mentioned scheme will cause the metal debris generated by the friction between the copper bar connecting seat and the motor controller to fall on the motor controller, resulting in the short circuit failure of the motor controller. Utility model content

[0005] The purpose of the present application is to provide an adapter seat, an electric drive assembly and a vehicle, which can solve the problem of metal debris falling on the motor controller and causing the short circuit failure of the motor controller.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0007] According to the first aspect of the present application, an adapter seat is provided for electrically connecting with a drive motor and a motor controller to realize the electrical connection between the drive motor and the motor controller, the adapter seat comprising an electrical connector and a collection member. The two ends of the electrical connector are respectively an input end and an output end. The input end is used for electrically connecting with the motor controller, and the output end is used for electrically connecting with the drive motor. The input end is provided with an input connecting hole. The collection member is arranged on the input end and connected with the input end. The collection member forms a collection cavity with an opening. The opening is arranged opposite to the input connecting hole and communicates with each other.

[0008] According to the above technical means, the electrical connector is electrically connected to the motor controller through its input end, and electrically connected to the drive motor through its output end. The input connection hole at the input end connects to the motor controller. The AC power output from the motor controller can be transmitted to the drive motor through the electrical connector and converted into mechanical energy by the drive motor. Metal debris generated by friction when the adapter is connected to the motor controller can enter the collection chamber through the opening. Alternatively, friction between the adapter and the motor controller in the collection chamber can cause metal debris to fall directly into the collection chamber. Collecting metal debris through the collection component prevents metal debris from falling onto the controller body and causing a short circuit fault.

[0009] In one possible implementation, the inner wall of the collection cavity is formed with internal threads.

[0010] According to the above technical means, a bolt can be passed through the input connection hole and extended into the collection cavity to engage with the internal thread. In this way, the electrical connector and the collection component are connected together by the bolt, ensuring the stability of current transmission.

[0011] In one possible implementation, there are multiple electrical connectors and multiple collection devices. Each electrical connector has an input terminal with a collection device. The adapter also includes a housing with an internal clearance channel, and the housing has a first opening and a second opening communicating with both ends of the clearance channel. The electrical connector passes through the clearance channel, and the input terminal and the output terminal extend out of the clearance channel through the first opening and the second opening, respectively.

[0012] According to the aforementioned technical means, the housing separates the electrical connectors located within the clearance channel from other components, preventing damage caused by collisions. Simultaneously, the clearance channel also serves to secure the electrical connectors, as they are typically sheet metal bent structures. This housing-secured connectors reduce deformation caused by changes in the input and output connection positions. Furthermore, the input and output terminals extend beyond the clearance channel through the first and second openings, ensuring that the housing does not interfere with the connection between the electrical connectors and the motor controller and drive motor.

[0013] In one possible implementation, the housing is formed with a fixing part located between the input end and the output end along the extending direction of the electrical connector, and disposed close to the electrical connector.

[0014] According to the above technical means, the fixing part of the housing can be fixed on the motor controller, and support is provided at the corresponding position of the electrical connector. This reduces the phenomenon of poor contact or even damage to the motor controller caused by warping and deformation of the electrical connector due to uneven stress when connecting the motor controller to the input end and then connecting the drive motor to the output end.

[0015] In one possible implementation, the fixing part is a fixing hole.

[0016] According to the above technical means, the adapter and the motor controller can be fastened by passing a bolt through the fixing hole and the corresponding threaded hole on the motor controller.

[0017] In one possible implementation, the housing further includes multiple positioning portions spaced apart. These positioning portions are used to connect to the motor controller and position the housing.

[0018] Based on the above technical means, before fixing the adapter, it can be connected to the housing of the motor controller through multiple positioning parts to limit the displacement of the adapter in the plane where the multiple positioning parts are located. This makes the fixing position of the adapter more accurate when it is fixed to the motor controller, and prevents the electrical connection from deforming due to the offset of the fixing position.

[0019] In one possible implementation, the positioning part is a positioning hole.

[0020] According to the above technical means, the displacement of the adapter in the plane where the positioning part is located can be limited by passing the positioning pin through the positioning hole and then through the corresponding pin hole on the motor controller.

[0021] According to a second aspect of this application, an electric drive assembly is provided, including a drive motor, a motor controller, and an adapter as described in any one of the first aspects. The motor controller includes a housing and a controller body, the controller body being electrically connected to the input terminal of an electrical connector. The drive motor is electrically connected to the output terminal of the electrical connector.

[0022] One end of the adapter is electrically connected to the controller body, and the other end of the adapter is electrically connected to the drive motor.

[0023] Using the aforementioned technical means, the adapter's housing can be fixed to the outer casing. Simultaneously, the AC power converted by the controller can be transmitted to the drive motor through the adapter.

[0024] In one possible implementation, the housing has an opening. The adapter also includes a casing with an interior forming a clearance channel, and the casing has a first opening and a second opening communicating with both ends of the clearance channel. Electrical connectors pass through the clearance channel, with the input and output terminals extending out of the clearance channel through the first and second openings, respectively. The casing includes a first connecting plate and a second connecting plate connected to each other. The second connecting plate is located on one side of the first connecting plate, with one end connected to the first connecting plate and the other end extending away from the first connecting plate. The interiors of the first and second connecting plates together form the clearance channel, and the end of the second connecting plate away from the first connecting plate forms a second opening. The first connecting plate covers the opening and is connected to the housing, while the second connecting plate passes through the opening.

[0025] According to the aforementioned technical means, the housing separates the electrical connectors located within the clearance channel from other components, preventing damage caused by collisions. Simultaneously, the clearance channel also serves to secure the electrical connectors, as they are typically sheet metal bent structures. This housing-secured connectors reduce deformation caused by changes in the input and output connection positions. Furthermore, the input and output terminals extend beyond the clearance channel through the first and second openings, ensuring that the housing does not interfere with the connection between the electrical connectors and the motor controller and drive motor.

[0026] Because the first connecting plate and the second connecting plate are connected and form a clearance channel inside, electrical connectors can pass through the interior of the first and second connecting plates. Thus, the input terminal can extend through a first opening on the end of the first connecting plate away from the second connecting plate and connect to the motor controller, while the output terminal can pass through an opening and connect to the drive motor through a second opening on the end of the second connecting plate away from the first connecting plate. Furthermore, the hot air generated by the drive motor is blocked at the opening near the drive motor. This prevents hot air from entering the housing through the opening and coming into contact with the cooler housing, causing condensation that could drip onto the controller body and cause malfunction. Simultaneously, the connection between the first connecting plate and the housing fixes the position of the connector within the housing, preventing collisions with other components that could cause malfunctions.

[0027] According to a third aspect of this application, a vehicle is provided, including the electric drive assembly described in the second aspect.

[0028] It should be noted that the technical effects of the electric drive assembly in the second aspect and the vehicle in the third aspect can be referred to the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] Electric vehicles, as representatives of new energy vehicles, are characterized by converting the electrical energy stored in the power battery into mechanical energy to drive the vehicle.

[0043] Generally speaking, the current output by the power battery is direct current (DC). The DC current is transmitted to the motor controller in the electric drive assembly of the vehicle. The motor controller integrates an inverter, which can convert the DC current output by the power battery into alternating current (AC). At the same time, it is input into the drive motor through electrical connectors. This AC current can be used by the drive motor. The drive motor uses the obtained AC current to generate a rotating magnetic field, which in turn causes the rotor of the drive motor to rotate, converting electrical energy into mechanical energy.

[0044] The power generated by the drive motor is transmitted to the wheels through the vehicle's transmission system, which may include components such as gearboxes and differentials. These components change the direction and speed of the power to adapt to different driving conditions.

[0045] Electrical connectors are widely used in the electric drive assemblies of vehicles to connect the motor controller and the drive motor, enabling communication between the two and transmitting current.

[0046] The electrical connector connects to the motor controller and the drive motor at both ends. The end connected to the motor controller is the input terminal, and the end connected to the drive motor is the output terminal. The input terminal is first fastened to the motor controller with bolts, and then the output terminal is fastened to the drive motor with bolts, thereby enabling the motor controller to input current to the drive motor.

[0047] Because of the simple structure of the aforementioned electrical connectors, and because the connection point between the electrical connector and the motor controller is typically made of metal for current transmission, metal shavings often occur during installation due to friction between the connector and the motor controller when they are being tightened. Since the connection point is close to the circuit board inside the motor controller, these metal shavings can fall onto the circuit board, causing a short circuit and resulting in a malfunction.

[0048] To address the problem of short-circuit faults in motor controllers caused by metal debris falling onto them, this application provides a vehicle, which can be an electric vehicle. To achieve the basic functions of the vehicle, it may include components such as a body, chassis, electric drive assembly, and electrical system.

[0049] The vehicle body may include a frame, doors, and windows. The frame forms the overall external shape of the vehicle and creates the passenger space. Doors can be rotatably connected to the frame, allowing the interior of the passenger space to be opened or closed. Windows can be mounted on the doors or the frame, providing passengers with a view of the outside environment.

[0050] The chassis may include components such as the transmission system and the drive system. The drive system drives the wheels to rotate. Depending on the drive method, drive systems can be classified as front-wheel drive, rear-wheel drive, and four-wheel drive. The transmission system transmits power generated by the power system to the wheels.

[0051] An electric drive system provides power to a vehicle, enabling it to perform basic driving functions. An electric drive system includes a drive motor, a motor controller, and an adapter.

[0052] To supply power to electrical components such as the drive motor, the electric drive assembly also includes a power battery. This power battery can be used to provide electrical energy.

[0053] The motor controller can convert the DC power output from the power battery into AC power used to drive the motor.

[0054] The motor controller includes a controller body, one end of an adapter is electrically connected to the controller body, and the other end of the adapter is electrically connected to the drive motor.

[0055] In this way, the AC power converted by the controller can be transmitted to the drive motor through the adapter.

[0056] In one possible implementation, such as Figure 1 As shown, Figure 1 This is a partial structural diagram of an electric drive assembly 100 provided in an embodiment of this application. The motor controller also includes a housing 11, which can isolate the controller body from the outside, thereby protecting the controller body.

[0057] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of an adapter 20 provided in an embodiment of this application. The adapter 20 includes a housing 21 and an electrical connector 22. Figure 2 and Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of an adapter 20 provided in an embodiment of this application. The two ends of the electrical connector 22 are an input end 221 and an output end 222, respectively. The input end 221 is used for electrical connection with the motor controller; specifically, the input end 221 is connected to the controller body. The output end 222 is used for electrical connection with the drive motor. Thus, the electrical connector 22 is electrically connected to the motor controller through the input end 221, and the electrical connector 22 is electrically connected to the drive motor through the output end 222.

[0058] The input terminal 221 has an input connection hole 2211. The input connection hole 2211 of the input terminal 221 is connected to the motor controller by bolts.

[0059] In this way, the AC power output by the motor controller can be transmitted to the drive motor through the electrical connector 22, and then converted into mechanical energy by the drive motor.

[0060] An obstacle avoidance channel is formed inside the housing 21, and the housing 21 has a first opening and a second opening that communicate with both ends of the obstacle avoidance channel. The electrical connector 22 passes through the obstacle avoidance channel, and the input end 221 and the output end 222 extend out of the obstacle avoidance channel through the first opening and the second opening, respectively.

[0061] In this way, the housing 21 separates the electrical connector 22, which is located in the clearance channel, from other components, preventing damage caused by collisions between the electrical connector 22 and other components. At the same time, the clearance channel also serves to fix the electrical connector 22, because the electrical connector 22 is usually a bent sheet metal structure. The electrical connector 22 fixed by the housing 21 reduces the deformation of the electrical connector 22 caused by changes in the connection position between the input end 221 and the output end 222.

[0062] In addition, the input terminal 221 and the output terminal 222 extend out of the clearance channel through the first opening and the second opening, so that the housing 21 will not affect the connection between the electrical connector 22 and the motor controller and the drive motor.

[0063] Among them, such as Figure 2 and Figure 3 As shown, the housing 21 includes a first connecting plate 211 and a second connecting plate 212 that are connected to each other. The second connecting plate 212 is located on one side of the first connecting plate 211, with one end connected to the first connecting plate 211 and the other end extending away from the first connecting plate 211.

[0064] The first connecting plate 211 and the second connecting plate 212 together form a clearance channel, and the end of the second connecting plate 212 away from the first connecting plate 211 forms a second opening. Because the first connecting plate 211 and the second connecting plate 212 are connected and form a clearance channel inside, the electrical connector 22 can pass through the interiors of the first connecting plate 211 and the second connecting plate 212. Thus, the input terminal 221 can extend through the first opening at the end of the first connecting plate 211 away from the second connecting plate 212 and connect to the motor controller, and the output terminal 222 can pass through the opening 111 (…). Figure 1 It is connected to the drive motor through a second opening at the end of the second connecting plate 212 away from the first connecting plate 211.

[0065] The outer casing 11 has an opening 111, and the first connecting plate 211 covers the opening 111. Figure 1 ), connected to the outer casing 11, the second connecting plate 212 passes through the opening 111 ( Figure 1 ).

[0066] Thus, the first connecting plate 211 covers the opening 111, as follows: Figure 1 As shown, the hot air generated by the drive motor is blocked at the opening 111 on the side near the drive motor. This prevents the hot air from entering the housing 11 through the opening 111 and coming into contact with the cooler housing 11, causing condensation. Condensation dripping onto the controller body could then cause a malfunction. Simultaneously, the connection between the first connecting plate 211 and the housing 11 secures the connecting seat within the housing 11, preventing collisions with other components that could lead to malfunctions.

[0067] like Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of an adapter 20 provided in an embodiment of this application. The adapter 20 also includes a collecting member 23, which is disposed on and connected to the input end 221. The collecting member 23 forms a collecting cavity with an opening. The opening is disposed opposite to and communicates with the input connection hole 2211.

[0068] In this way, metal debris generated by friction when the adapter 20 connects to the motor controller can enter the collection chamber through the opening. Alternatively, the adapter 20 and the motor controller may rub against each other in the collection chamber, causing metal debris to fall directly into the collection chamber. Collecting metal debris through the collection component 23 prevents metal debris from falling onto the controller body and causing a short circuit fault in the controller body.

[0069] For example, the collection component 23 is welded to the input terminal 221.

[0070] In one possible implementation, the inner wall of the collection cavity is formed with internal threads.

[0071] In this way, the bolt can be passed through the input connection hole 2211 and extended into the collection cavity to engage with the internal thread. Thus, the electrical connector 22 and the collection component 23 are connected together by bolts, ensuring the stability of current transmission.

[0072] In one possible implementation, there are multiple electrical connectors 22 and multiple collectors 23. Each electrical connector 22 has an input terminal 221 with a collector 23.

[0073] In this way, multiple electrical connectors 22 can transmit alternating current of different phases. At the same time, metal debris generated when each input terminal 221 is connected to the motor controller can be collected by the corresponding collection unit 23.

[0074] For example, there are three electrical connectors 22, which are used to transmit current in the three phases of U, V and W respectively.

[0075] Furthermore, an isolation wall is provided between each electrical connector 22 within the clearance channel to prevent phase-to-phase short circuits caused by contact between the electrical connectors 22.

[0076] In one possible implementation, such as Figure 2 As shown, the housing 21 has a fixing part 2111. Along the extending direction of the electrical connector 22, the fixing part 2111 is located between the input end 221 and the output end 222, and is disposed close to the electrical connector 22.

[0077] In this way, the fixing part 2111 of the housing 21 can be fixed on the outer shell 11, and support is provided at the corresponding position of the electrical connector 22. This reduces the phenomenon that poor contact or even damage to the motor controller may occur due to warping and deformation of the electrical connector 22 caused by uneven stress when connecting the motor controller and the input terminal 221 and then connecting the drive motor and the output terminal 222.

[0078] In one possible implementation, the number of fixing parts 2111 can be one. This can reduce the warping deformation of the electrical connector 22 to a certain extent.

[0079] In one possible implementation, there can be multiple fixing parts 2111. This allows the adapter 20 to fit more closely to the housing 11, reducing the degree of warping deformation of the electrical connector 22.

[0080] In order to fix the fixing part 2111 to the outer casing 11, the fixing part 2111 may include various forms.

[0081] In one possible implementation, the fixing part 2111 is a fixing hole.

[0082] In this way, the adapter 20 can be securely connected to the housing 11 by passing a bolt through the fixing hole and the corresponding threaded hole 112 on the housing 11.

[0083] In one possible implementation, such as Figure 2 As shown, the housing 21 also has a plurality of positioning parts 2112, which are spaced apart. The positioning parts 2112 are used to connect with the motor controller to position the housing 21.

[0084] In this way, before fixing the adapter 20, it can be connected to the housing 11 of the motor controller through multiple positioning parts 2112 to limit the displacement of the adapter 20 in the plane where the multiple positioning parts 2112 are located, so that the fixing position of the adapter 20 can be more accurate when it is fixed with the motor controller, and prevent the electrical connector 22 from deforming due to the offset of the fixing position.

[0085] In order to limit the displacement of the adapter 20 in the plane where the positioning part 2112 is located, the positioning part 2112 may include various forms.

[0086] In one possible implementation, the positioning part 2112 is a positioning hole.

[0087] In this way, the displacement of the adapter 20 in the plane of the positioning part 2112 can be limited by the positioning pin passing through the positioning hole and then through the corresponding pin hole 113 on the outer shell 11.

[0088] In one possible implementation, the positioning part 2112 can be a positioning post.

[0089] In this way, the displacement of the adapter 20 in the plane of the positioning part 2112 can be limited by directly inserting the positioning pin into the corresponding pin hole 113 on the outer shell 11.

[0090] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
