Description

Technical Field

[0001] This utility model relates to the automotive field, and in particular to a seat motor, a body control system, and an automobile. Background Technology

[0002] refer to Figure 1A The current vehicle body domain controller is a core component of modern automotive electrical and electronic architecture, responsible for integrating and managing functions traditionally executed by multiple independent body control modules. Its internal structure and system design are complex. Current vehicle body domain controllers typically integrate multiple seat motor control units and transmit control commands to each seat motor via CAN bus, with the seat motor merely acting as an execution unit. Thus, the domain controller must handle complex seat motor control logic, resulting in complex hardware and software design, high development costs, and long development cycles. Furthermore, each seat motor requires long-distance wiring harnesses to connect the domain controller and the seat motor; and the domain controller must be equipped with higher computing power and higher-specification chips and hardware, significantly increasing system costs.

[0003] refer to Figure 1B Some manufacturers separate the control units of multiple seat motors integrated in the domain controller and create independent motor control units. The domain controller sends instructions to the independent motor control unit via CAN line, and the motor control unit then connects to each seat motor via multiple CAN lines to send execution instructions to each seat motor. In this way, although the hardware and software design and development costs of the domain controller are reduced, it is necessary to design and install independent motor control units and require independent motor control unit housings.

[0075] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0076] refer to Figure 1AThe current vehicle body domain controller is a core component of modern automotive electrical and electronic architecture, responsible for integrating and managing functions traditionally executed by multiple independent body control modules. Its internal structure and system design are complex. Current vehicle body domain controllers typically integrate multiple seat motor control units and transmit control commands to each seat motor via CAN bus, with the seat motor merely acting as an execution unit. Thus, the domain controller must handle complex seat motor control logic, resulting in complex hardware and software design, high development costs, and long development cycles. Furthermore, each seat motor requires long-distance wiring harnesses to connect the domain controller and the seat motor; and the domain controller must be equipped with higher computing power and higher-specification chips and hardware, significantly increasing system costs.

[0077] refer to Figure 1B Some manufacturers separate the control units of multiple seat motors integrated in the domain controller and create independent motor control units. The domain controller sends instructions to the independent motor control unit via CAN line, and the motor control unit then connects to each seat motor via multiple CAN lines to send execution instructions to each seat motor. In this way, although the hardware and software design and development costs of the domain controller are reduced, it is necessary to design and install independent motor control units and require independent motor control unit housings.

[0078] Therefore, refer to Figure 2 This application provides a seat motor in which the control units of multiple seat motors originally integrated into a domain controller are independently designed as miniaturized controllers and integrated into the existing seat motors. This reduces the length of the wiring harness, lowers the difficulty and cost of system development, and also reduces the hardware cost of the independent motor control unit.

[0079] For example, this application discloses an automobile, including a body control system, wherein the body control system includes a domain controller and a seat motor, and the domain controller and the seat motor are connected via a LIN bus.

[0080] For example, refer to Figures 3 to 4 The seat motor includes: a motor body 100, an integrated housing 200, a control PCB board 300, and a Hall effect PCB board 400. The integrated housing 200 includes a first mounting portion 210 and a second mounting portion 220. The first mounting portion 210 is located radially (i.e.,...) of the motor body 100. Figure 3 The second mounting part 220 is provided on the outer side of the motor body 100 in the axial direction (i.e., the Y direction shown). Figure 3 On one side (in the X direction shown), the first mounting part 210 and the second mounting part 220 are integrally formed; the control PCB board 300 is mounted on the first mounting part 210; the Hall PCB board 400 is mounted on the second mounting part 220, and the control PCB board 300 and the Hall PCB board 400 are electrically connected and arranged parallel to each other. Figure 3A visible).

[0081] Using the above technical solution, the control PCB board 300 is mounted on the first mounting part 210, and the Hall PCB board 400 is mounted on the second mounting part 220. The control PCB board 300 and the Hall PCB board 400 are electrically connected. In this way, the control unit (i.e., the control PCB board 300) is also integrated into the seat motor. That is, the control unit originally integrated into the domain controller is integrated into the seat motor. From a hardware perspective: the integration level of the domain controller hardware module is reduced (the control unit module of the seat motor is removed), thereby reducing complexity and chip computing power. Furthermore, since the control unit is also integrated into the seat motor, there is no need for a wiring harness to connect the actuator of the seat motor to the domain controller, reducing the amount of wiring harness used from the domain controller to the seat motor. From a software perspective: the domain controller software module is removed, reducing the software development time and cost of the domain controller. At the same time, the design and assembly concept of this seat motor structure is modular, facilitating upgrades and modifications to the entire vehicle system.

[0082] It should be noted that the seat motor provided in this application embodiment is not only applicable to seat leveling motors, but also to other motors, such as seat backrest motors. Figure 13 As shown), seat height motor ( Figure 14 (as shown) and seat diving motor ( Figure 15 (As shown).

[0083] Specifically, refer to Figure 5 The motor body 100 along the axial direction (i.e. Figure 5 Extending in the X direction (as shown), and hollow inside, with a motor shaft 130 inside, the motor shaft 130 is along the axial direction of the motor body 100 (i.e., Figure 5 Extending along the axial direction of the motor body 100 (as shown in the X direction), the motor body 100 includes a first end 140 and a second end 150 (i.e., the aforementioned axial side). The second end 150 is provided with two snap-fit ​​grooves 120, which are located along the circumference of the motor body 100 (i.e., along the X direction). Figure 5 As shown in direction A, the integrated housing 200 is inserted into the card slot 120 to connect with the motor body 100.

[0084] It should be noted that the specific number and shape of the snap-fit ​​slots 120 are not limited in this application embodiment, as long as the integrated housing 200 can be connected to the motor body 100. For example, three snap-fit ​​slots 120 can also be provided.

[0085] It is understood that the embodiments of this application do not limit the connection method between the integrated housing 200 and the motor body 100, and it can also be as follows: Figures 13 to 15 The screw shown is a 900 connection.

[0086] For example, refer to Figure 3A The seat motor also includes an upper cover 500, which covers the first mounting portion 210 and is connected to the first mounting portion 210 to form a first receiving portion 230. The control PCB board 300 is located in the first receiving portion 230. The upper cover 500 provides a sealing and protection function for the control PCB board 300, preventing interference from the external environment to the control PCB board 300.

[0087] Specifically, refer to Figure 4 The top cover 500 has an opening on the side facing the first mounting part 210, and the first mounting part 210 has an opening on the side facing the top cover 500. After the top cover 500 is placed on the first mounting part 210, the two openings are connected to form a first receiving part 230, and the control PCB board 300 is located in the first receiving part 230.

[0088] For example, the upper cover 500 is connected to the first mounting portion 210 by a snap-fit ​​connection. Specifically, along the circumference of the motor body 100 (i.e., Figure 4 (As shown in direction A), the upper cover 500 has locking holes 510 on both sides, and the first mounting part 210 has a corresponding protrusion 211. The protrusion 211 is inserted into the locking hole 510 to realize the connection between the upper cover 500 and the first mounting part 210.

[0089] It should be noted that the specific shapes of the protrusion 211 and the card hole 510 are not limited in the embodiments of this application, as long as the protrusion 211 can be confined within the card hole 510. For example, the card hole 510 shown in the embodiments of this application can be an inverted trapezoid, and the side of the protrusion 211 can be a trapezoid.

[0090] It is understood that the embodiments of this application do not limit the connection method between the top cover 500 and the first mounting part 210. For example, the top cover 500 and the first mounting part 210 can also be connected by other methods such as adhesive.

[0091] For example, refer to Figure 6 The first receiving part 230 is provided with four pillars 231. The four pillars 231 are spaced apart along the outer periphery of the first mounting part 210. The upper surfaces of the four pillars 231 are on the same horizontal plane. The control PCB board 300 is placed on the upper surfaces of the four pillars 231, so that the control PCB board 300 placed on the upper surfaces of the pillars 231 is in a horizontal state.

[0092] For example, one of the columns 231 has a limiting post 232 on its upper surface, and the control PCB board 300 has a first opening 310 corresponding to the limiting post 232. The other column 231 has a limiting post 232 next to it, and the control PCB board 300 has a first opening 310 corresponding to the limiting post 232. The two limiting posts 232 are located on the diagonal of the control PCB board 300. The first opening 310 passes through and connects to the limiting post 232 to limit and guide the control PCB board 300. This can limit the back-and-forth movement of the control PCB board 300 and also allow the control PCB board 300 to be accurately installed in the first mounting part 210.

[0093] It should be noted that the specific number of limiting posts 232 is not limited in this application embodiment. It is also possible that all four posts 231 are provided with limiting posts 232. Similarly, the specific number of first openings 310 is not limited in this application embodiment, as long as it is the same as the number of limiting posts 232.

[0094] It is understood that the specific position of the limiting post 232 is not limited in the embodiments of this application. For example, the two limiting posts 232 may be located on the diagonal of the control PCB board 300, or the two limiting posts 232 may be located on the same side of the control PCB board 300, or the two limiting posts 232 may be located on the upper surface of two of the posts 231. The specific selection depends on the internal space of the first mounting part 210.

[0095] For example, refer to Figure 7 and Figure 8 The first mounting part 210 has an arc-shaped mounting surface 212 on the side away from the upper cover 500. The arc-shaped mounting surface 212 is attached to the radial outer surface of the motor body 100, thereby reducing the spatial installation height and improving the installation stability.

[0096] For example, refer to Figure 3A and Figure 4 The control PCB board 300 and the Hall PCB board 400 are electrically connected via six first connection pins 600. A first opening 110 is provided at one axial end (i.e., the second end 150) of the motor body 100, extending radially along the motor body 100 (i.e., along the radial direction of the motor body 100). Figure 3A (As shown in the Y direction), the first mounting part 210 is provided with a second opening 213 that is directly opposite to and connected to it, and six first connecting pins 600 pass through the first opening 110 and the second opening 213 to connect to the control PCB board 300.

[0097] Specifically, the Hall PCB board 400 has six first solder points 410, and the control PCB board 300 has six second solder points 320. One end of the six first connecting pins 600 passes through the first opening 110 and the second opening 213 and is soldered to the second solder point 320 of the control PCB board 300. The other end of the first connecting pins 600 is soldered to the first solder point 410 of the Hall PCB board 400.

[0098] It should be noted that the shapes of the first opening 110 and the second opening 213 are not limited in this embodiment, as long as the first connecting PIN 600 can pass through. For example, the first opening 110 and the second opening 213 shown in this embodiment are rectangular, and their shapes can also be different. Similarly, the number of the first connecting PIN 600 is not limited in this embodiment; it can be selected according to actual needs, such as five, eight, or ten.

[0099] For example, the second mounting portion 220 includes a rear cover 221, the motor body 100 is hollow inside, and the rear cover 221 is connected to the end of the motor body 100 on one axial side (i.e., the second end 150) to form a second receiving portion 240. Figure 3A As can be seen, the second receiving part 240 is connected to the first opening 110 and the second opening 213 and is equipped with the Hall PCB board 400.

[0100] For example, refer to Figure 9 The integrated housing 200 also includes a connector port 800, which is located on the side of the rear cover 221 facing away from the motor body 100. However, the specific location of the connector port 800 is not limited in this embodiment, and the connector port 800 can also be as follows: Figures 13 to 15 It is located on the side of the first mounting portion 210 away from the rear cover 221. That is to say, the specific location of the seat motor connector port 800 will vary depending on the type of seat.

[0101] For example, combined Figure 3A and Figure 4 The second receiving part 240 is provided with four second connecting pins 810, and the control PCB board 300 is provided with four third solder points 330. One end of the four second connecting pins 810 passes through the first opening 110 and the second opening 213 and is soldered to the third solder point 330 of the control PCB board 300. The other end of the second connecting pins 810 is located in the connector port 800. The connector port 800 is integrally formed with the first mounting part 210 and the second mounting part 220.

[0102] It should be noted that the number of the second connection PIN810 is not limited in this application embodiment. The number can be selected according to actual needs, such as five, eight, ten, etc.

[0103] For example, a reinforcing member 820 is provided on the side of the back cover 221 facing away from the connector port 800. The other end of the second connecting PIN 810 passes through the reinforcing member 820 so that it is located inside the connector port 800. By providing the reinforcing member 820, the thickness through which the second connecting PIN 810 passes is increased, thereby increasing the load-bearing capacity of the back cover 221. Specifically, the reinforcing member 820 consists of two reinforcing plates 821, which are spaced apart and both protrude in the direction toward the second connecting PIN 810.

[0104] For example, refer to Figure 10 and Figure 11 The rear cover 221 has a placement portion 222 and a locking portion 223 on the side facing the motor body 100. The placement portion 222 is located on the outer periphery of the rear cover 221 and is spaced apart along the outer periphery of the rear cover 221. The placement portion 222 has two fixing slots 224 located on the same horizontal plane. The Hall PCB board 400 is inserted into the fixing slot 224 to limit the Hall PCB board 400 to the placement portion 222. Along the radial direction of the motor body 100 (i.e., Figure 10 (As shown in the Y direction), the latch 223 is located below the reinforcing member 820. The latch 223 includes a limiting latch 225. The Hall PCB board 400 has a corresponding latch groove 420. The limiting latch 225 passes through the latch groove 420 to limit the Hall PCB board 400 (as shown in the Y direction). Figure 11 visible).

[0105] With the above technical solution, the two fixing slots 224 are on the same horizontal plane, so that the Hall PCB board 400 inserted into the fixing slot 224 is also in a horizontal state, and the radial displacement of the Hall PCB board 400 is limited to prevent it from moving radially along the motor body 100. After the limiting buckle 225 passes through the buckle slot 420, it can limit the Hall PCB board 400 from moving axially along the motor body 100.

[0106] For example, the seat motor also includes a brush 700. A brush holder 710 is provided on the side of the rear cover 221 facing the motor body 100. The brush holder 710 is spaced along the outer edge of the rear cover 221. A brush fixing groove 720 is provided on the side of the brush holder 710 facing the brush 700. The brush 700 is confined in the brush fixing groove 720 to fix it to the brush holder 710. The brush 700 is connected to the Hall PCB board 400 through a connecting wire (not shown in the figure).

[0107] For example, refer to Figure 12 Along the axial direction of the motor body 100 (i.e. Figure 12 (As shown in the X direction), a connector 520 is provided on the side of the upper cover 500 away from the rear cover 221. The connector 520 is attached to the radial outer surface of the motor body 100. The interior of the connector 520 is hollow to form a connection hole 521. The upper cover 500 and the motor body 100 are connected by a strip 522. The strip 522 passes through the connection hole 521 and wraps around the radial outer surface of the motor body 100. It can be understood that it can also be like... Figures 13 to 15 No strip 522 is set. Because... Figures 13 to 15 The seat motor shown has a first mounting portion 210 extending axially along the motor body 100 with a length less than that shown. Figure 3 The length of the seat leveling motor shown is such that its installation stability can be secured by an extended screw 900.

[0108] In summary, the seat motor provided in this embodiment connects two parallel PCBs (control PCB 300 and Hall PCB 400) via six first connecting pins 600, and is simultaneously fixed to the integrated housing 200. After the top cover 500 is installed with the first mounting part 210, it is further fixed to the motor body 100 by the strip 522. The integrated housing 200 integrates the connector port 800, the rear cover 221 (i.e., the end cover of the second end 150 of the motor body 100), the first mounting part 210 (for mounting the control PCB 300), and the brush holder 710. The integrated housing 200 is the main carrier between the Hall PCB 400 and the control PCB 300. These parts are assembled together by the first connecting pins 600 and the second connecting pins 810. The top cover 500 and the strip 522 serve to protect and fix the integrated housing 200. The integrated housing 200 and the motor body 100 are connected by snap-fit ​​or screws 900.

[0109] This offers at least the following advantages: From an electronic system perspective: it reduces the amount of wiring harness used from the domain controller to the seat motor; it lowers the integration of the domain controller hardware modules, reducing complexity and chip computing power; and it eliminates the seat controller software module, reducing the software development time and cost of the domain controller. From a seat motor structure perspective: the seat motor controller saves on the cost of the housing and connectors of an independent controller; the design concept of the control PCB board can be standardized and applied to other seat motors; the seat motor structure and the design and assembly concept of the motor can be modularized, facilitating the upgrading and modification of the entire vehicle system; and the arc-shaped contour design of the integrated housing fits the motor body, reducing the installation space height.

[0110] The Hall PCB board 400 is pushed into the fixed position of the back cover 221 along the horizontal fixing groove 224 to ensure the horizontal position of the Hall PCB board 400. The limiting buckle 225 passes through the corresponding buckle groove 420 on the Hall PCB board 400 to prevent the Hall PCB board 400 from falling off. Then, the brush 700 is fixed on the brush fixing seat 710, thereby mounting the brush 700 on the integrated housing 200. Then, the other end of the first connecting PIN 600 is soldered to the first solder point 410 of the Hall PCB board 400, and the brush 700 is soldered to the fourth solder point (not shown) of the Hall PCB board 400 through the connecting wire.

[0111] Then, the control PCB board 300 is placed on the upper surface of the column 231 and passes through the limiting column 232 through the first opening 310, thereby installing the control PCB board 300 in the first mounting part 210. Then, one end of the first connecting PIN 600 passes through the first opening 110 and the second opening 213 and is soldered to the second solder point 320 of the control PCB board 300. One end of the second connecting PIN 810 passes through the first opening 110 and the second opening 213 and is soldered to the third solder point 330 of the control PCB board 300. The other end of the second connecting PIN 810 is located inside the connector port 800.

[0112] Finally, the arc-shaped mounting surface 212 of the integrated housing 200 fits against the radial outer surface of the motor body 100, and the rear cover 221 is snapped onto the motor body 100 by snapping onto the snap-fit ​​groove 120 of the second end 150. The upper cover 500 is connected to the integrated housing 200 by a snap-fit ​​connection, and the strip 522 fixes the upper cover 500 and the motor body 100 through the connecting hole 521 of the upper cover 500.

[0113] Other types of seat motors, such as seat back motors ( Figure 13 As shown), seat height motor ( Figure 14 (as shown) and seat diving motor ( Figure 15 The structural design concept is similar to that shown, except that the position of the connector port 800 is changed. The motor body 100 and the integrated housing 200 are fixed by screws 900, and the additional fixing of the top cover 500 by the strip 522 is removed.
