Description

Technical Field

[0001] The present application relates to the field of controller technology, and in particular to a circuit board mounting structure, a controller and a vehicle. Background Art

[0002] The electric power steering controller is a power steering controller that relies on a motor to provide auxiliary torque and is an essential component of the vehicle steering control system.

[0003] In the related art, the circuit board structure of the steering controller includes two layers of circuit boards (Printed Circuit Board, PCB for short), wherein the lower PCB board is installed on a heat dissipation fixing seat, and the upper PCB board is fixed on the top of the lower PCB board through a support column. Since the lower PCB board is arranged with power devices, motor interfaces, inductors, etc. on both sides, and the space is limited, currently only two screws are used to fix the lower PCB board in the middle, but this form of fixation is unstable and the connection is not reliable. In addition to factors such as assembly errors, the power part of the lower PCB board will not fit well with the heat dissipation fixing seat, affecting heat dissipation. If the number of screws on the lower PCB board is increased, it will inevitably take up more circuit board space, which is not conducive to the layout of the circuit board and the electrical performance of the circuit board.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In the related art, the circuit board structure of the steering controller includes two layers of circuit boards, the lower PCB board is installed on the heat dissipation fixing seat, and the upper PCB board is fixed on the top of the lower PCB board through a support column. Since the lower PCB board is arranged with power devices, motor interfaces, inductors, etc. on both sides, and the space is limited, currently only two screws are used to fix the lower PCB board in the middle. However, this form of fixation is unstable and the connection is not reliable. Coupled with factors such as assembly errors, the power part of the lower PCB board will not fit well with the heat dissipation fixing seat, affecting the heat dissipation. If the number of screws on the lower PCB board is increased, it will inevitably take up more circuit board space, which is not conducive to the layout of the circuit board and the electrical performance of the circuit board.

[0041] In view of this, an embodiment of the present application provides a circuit board installation structure.

[0042] See also Figure 1 and Figure 2A circuit board mounting structure includes a fixing base 1, a first circuit board 5, a mounting sleeve 2, and an abutment member; the fixing base 1 is provided with a plurality of support columns 11, and the first circuit board 5 passes through the plurality of support columns 11 and is connected to the fixing base 1.

[0043] The mounting sleeve 2 is sleeved on the supporting column 11 , one end of the mounting sleeve 2 abuts against the first circuit board 5 , and the other end of the mounting sleeve 2 abuts against the abutting member to fix the first circuit board 5 to the fixing seat 1 .

[0044] Specifically, for the electric power steering, the circuit board installation structure includes two layers of circuit boards, namely the first circuit board 5 and the second circuit board 6. The circuit board installation structure is connected to the end of the motor, and is connected by the fixing seat 1 and the end of the motor by pressing. In order to match the shape of the motor, the shape of the fixing seat 1 and the circuit board can be set to be disc-shaped. The fixing seat 1 serves as the installation base for the two layers of circuit boards. Four support columns 11 are arranged on the fixing seat 1. The first circuit board 5 is installed on the fixing seat 1 through the support columns 11; the four support columns 11 are distributed on the edge of the fixing seat 1 to form four corner supports for installing the second circuit board 6. The second circuit board 6 is arranged above the first circuit board 5 and connected to the top of the support column 11.

[0045] The abutment piece is connected to one end of the support column 11 away from the fixing seat 1 and abuts against the mounting sleeve 2 to apply force to the mounting sleeve 2, thereby pressing the first circuit board 5 downward to fix the first circuit board 5 to the fixing seat 1.

[0046] Optionally, the abutment member includes a gasket 3 and a screw 4, a threaded hole is provided inside the support column 11, and a through hole for the screw 4 to pass through is correspondingly provided on the second circuit board 6. The top end of the support column 11 away from the fixing seat 1 is lower than the end of the mounting sleeve 2 away from the fixing seat 1.

[0047] Since the end surface of the mounting sleeve 2 away from the fixing seat 1 is higher than the supporting column 11, during the assembly process, when the screw 4 is used to pass through the gasket 3 and the second circuit board 6 to connect and lock the second circuit board 6 and the supporting column 11, the gasket 3 will press the mounting sleeve 2 from above, so that the mounting sleeve 2 is subjected to force and thus pressed against the first circuit board 5. At this time, the first circuit board 5 is subjected to a downward pressing force at the position of the supporting column 11, and thus obtains the same fastening effect as the installation screws, thereby improving the stability of the installation. At the same time, it does not occupy the installation space on the first circuit board 5, thereby ensuring the electrical performance of the circuit board.

[0048] In an optional embodiment, when the gasket 3 and the screw 4 are used to connect and lock the second circuit board 6 and the support column 11, the gasket 3 presses the second circuit board 6 and then the mounting sleeve 2. Specifically, the mounting sleeve 2 is sleeved on the outside of the support column 11, one end of the mounting sleeve 2 abuts against the first circuit board 5, and the end surface of the other end is higher than the top surface of the support column 11. The bottom surface of the second circuit board 6 is located above the support column 11 and abuts against the mounting sleeve 2. The gasket 3 is located above the second circuit board 6. The screw 4 passes through the gasket 3 and the second circuit board 6 in turn, and is connected and locked with the support column 11 inside the mounting sleeve 2. After locking, the gasket 3 presses the second circuit board 6, and the mounting sleeve 2 abuts between the second circuit board 6 and the first circuit board 5. The pressure is transmitted from the gasket 3 to the second circuit board 6, and then from the second circuit board 6 to the mounting sleeve 2, and finally from the mounting sleeve 2 to the first circuit board 5, so as to achieve the fastening of the first circuit board 5.

[0049] In another preferred embodiment, when the gasket 3 and the screw 4 are used to connect and lock the second circuit board 6 and the support column 11, the gasket 3 directly presses the mounting sleeve 2, and the specific configuration is as follows:

[0050] The mounting sleeve 2 includes a main body 21 and a protrusion connected to one end of the main body 21; the main body 21 is sleeved on the outer periphery of the support column 11, and an end face of the main body 21 away from the protrusion abuts against the first circuit board 5, an end face of the main body 21 close to the protrusion is lower than the top surface of the support column 11, and the top surface of the protrusion is higher than the top surface of the support column 11; the protrusion protrudes from the surface of the second circuit board 6, and the abutment member presses against the protrusion.

[0051] See also Figure 3-Figure 5 Taking the cylindrical support column 11 as an example, the main body 21 is matched and set to a cylindrical shape, which is sleeved on the outer periphery of the support column 11, and the protrusion is connected to the end of the main body 21 away from the first circuit board 5. The bottom end face of the main body 21 abuts against the surface of the first circuit board 5, and the protrusion is located upward at the top of the main body 21.

[0052] In an optional embodiment, the position of the protrusion can be set at the edge of the second circuit board 6. When assembling, the second circuit board 6 is placed on the top of the support column 11, the bottom surface of the second circuit board 6 contacts the top surface of the support column 11, and the top surface of the protrusion is slightly higher than the surface of the second circuit board 6. When locking, the gasket 3 is used to press the protrusion from above the second circuit board 6, and the screw 4 passes through the gasket 3 and the second circuit board 6 in turn, and is screwed into the inside of the support column 11 to connect and fix the second circuit board 6 and the support column 11.

[0053] By setting the protrusion so that the protrusion is slightly higher than the surface of the second circuit board 6, the gasket 3 can directly press the protrusion during locking to make the mounting sleeve 2 bear force. At the same time, since the end surface of the top of the main body 21 is lower than the top surface of the support column 11, the bottom surface of the second circuit board 6 abuts against the support column 11 instead of the main body 21 during assembly. The mounting sleeve 2 is pressed tightly between the gasket 3 and the first circuit board 5, and the pressure is directly transmitted from the gasket 3 to the mounting sleeve 2, and then to the first circuit board 5. In this way, the contact between the second circuit board 6 and the mounting sleeve 2 can be reduced, thereby preventing the second circuit board 6 from being deformed by the extrusion stress of the mounting sleeve 2, preventing the components installed on the second circuit board 6 from being damaged and cracked, and ensuring that the second circuit board 6 can work normally and stably.

[0054] In another optional embodiment, the protrusion may be arranged in a manner of passing through the second circuit board 6. A mounting hole is provided on the second circuit board 6 corresponding to the protrusion, and the protrusion passes through the mounting hole and protrudes from the surface of the second circuit board 6.

[0055] During assembly, the second circuit board 6 is placed on the top of the support column 11, so that the protrusion passes through the mounting hole on the second circuit board 6 and protrudes from the surface of the second circuit board 6, and the gasket 3 is used to press the protrusion from above the second circuit board 6. The screw 4 passes through the gasket 3 and the second circuit board 6 in turn, and is screwed into the inside of the support column 11 to connect and fix the second circuit board 6 and the support column 11.

[0056] Furthermore, the mounting hole and the protrusion are clearance-matched. Through the clearance-matching method, the protrusion of the mounting sleeve 2 passes through the second circuit board 6, but does not contact the second circuit board 6, but is pressed against the gasket 3, thereby avoiding the extrusion stress of the mounting sleeve 2 on the second circuit board 6 to the greatest extent.

[0057] According to the actual assembly needs, the installation sleeve 2 can be installed on all the support columns 11, or the installation sleeve 2 can be installed on one or several support columns 11. In the case where the installation sleeve 2 is installed on some support columns 11, the end surface of the top of the main body 21 is lower than the top surface of the support column 11, which can prevent the second circuit board 6 from being lifted by the installation sleeve 2 at this position. The second circuit board 6 is supported on the support column 11, and the horizontal height of all support columns 11 is consistent, which can ensure the horizontality of the installation of the second circuit board 6. In this way, the stress on the second circuit board 6 is minimized, which can avoid process problems such as component damage, solder cracking of pads, and circuit board wiring breakage.

[0058] As an example, the distance between the end surface of one end of the main body 21 close to the protrusion and the top surface of the support column 11 can be set to 0.5 mm.

[0059] The shape of the support column 11 can be set to be the same or different according to the actual space size, and its cross section can be circular, polygonal or other shapes. The column body of the support column 11 can be as large as possible without occupying the circuit board installation space. The installation gap between the mounting sleeve 2 and the support column 11 is as small as possible under the condition of meeting mass production. If the gap is too large, it is easy to loosen the installation and affect the installation stability. If the gap is too small, it may not be assembled due to processing and assembly errors. It can be controlled within 0.2mm-0.3mm.

[0060] Optionally, the number of the protrusions is at least two, and at least two of the protrusions are arranged opposite to each other.

[0061] As an example, two protrusions may be provided, including a first protrusion 22 and a second protrusion 23. Figure 3 As shown, in order to match the cylindrical main body 21, the shape of the first protrusion 22 and the second protrusion 23 can be set to an arc shape, and the height of the two is consistent to ensure the horizontality during assembly. The first protrusion 22 and the second protrusion 23 are arranged relative to each other, so that when the gasket 3 presses the protrusion downward, the pressure can be transmitted axially along the main body 21 from one opposite side, and the force distribution is relatively balanced. The shape and size of the first protrusion 22 and the second protrusion 23 may not be exactly the same, and can be set according to actual needs.

[0062] See also Figure 6 The second circuit board 6 is provided with a first mounting hole 61 and a second mounting hole 62 corresponding to the first protrusion 22 and the second protrusion 23 respectively. During assembly, the first protrusion 22 passes through the first mounting hole 61 and protrudes from the surface of the second circuit board 6, and the second protrusion 23 passes through the second mounting hole 62 and protrudes from the surface of the second circuit board 6.

[0063] In practical applications, the shape, number and distribution of the protrusions can be reasonably adjusted according to the shape of the second circuit board 6 and the installation space.

[0064] Optionally, the thickness of the main body 21 is greater than or equal to 1 mm.

[0065] Specifically, during assembly, the bottom end face of the main body 21 abuts against the first circuit board 5. When the gasket 3 presses the protrusion, the pressure is transmitted downward from the protrusion along the axial direction of the main body 21 to the bottom end of the main body 21, thereby pressing the first circuit board 5. The area of ​​contact between the main body 21 and the first circuit board 5 affects the fastening effect of the first circuit board 5. Setting the thickness of the main body 21 to be greater than or equal to 1 mm can ensure that the installation sleeve 2 fully contacts and presses the first circuit board 5 during assembly, thereby ensuring the stability of the installation.

[0066] Optionally, the mounting sleeve 2 further includes a positioning portion 24, the positioning portion 24 is connected to one end of the mounting sleeve 2 close to the fixing seat 1, a positioning hole matching the size of the positioning portion 24 is opened on the first circuit board 5, and the positioning portion 24 is arranged in the positioning hole.

[0067] Specifically, the mounting sleeve 2 is provided with a positioning portion 24 near the fixing seat 1, and a corresponding positioning hole is opened on the first circuit board 5. During assembly, the positioning portion 24 faces the first circuit board 5, and the main body 21 is mounted on the support column 11, so that the positioning portion 24 is inserted into the positioning hole. The positioning portion 24 cooperates with the positioning hole to play a positioning role, prevent the mounting sleeve 2 from rotating, ensure the accurate position of the protrusion, and ensure that the protrusion can accurately cooperate with the mounting hole on the second circuit board 6 during subsequent assembly, avoiding interference, and improving the convenience and accuracy of assembly.

[0068] The positioning portion 24 can be configured to be columnar or block-shaped, and the specific shape and size can be reasonably adjusted according to the installation space of the first circuit board 5 .

[0069] Optionally, the material of the mounting sleeve 2 includes plastic.

[0070] Specifically, the material of the mounting sleeve 2 is preferably a plastic with a certain elasticity and high temperature resistance. The elastic material allows the mounting sleeve 2 to be slightly deformed when subjected to force, and the screws 4 and gaskets 3 can flatten the protrusions protruding from the surface of the second circuit board 6 when locking, thereby achieving the locking of the second circuit board 6 and the support column 11; in addition, since the power part of the circuit board will generate heat when working, the use of high temperature resistant materials can prevent the mounting sleeve 2 from aging and softening due to heat, which is beneficial to extending the service life of the mounting sleeve 2 and ensuring installation reliability.

[0071] Optionally, a pad 12 protruding toward the first circuit board 5 is provided on the fixing seat 1 , and the bottom surface of the first circuit board 5 abuts against the top surface of the pad 12 at one end away from the fixing seat 1 .

[0072] For the electric power steering, the circuit board mounting structure is connected to the end of the motor, and is connected by pressing the fixing seat 1 with the end of the motor housing. The fixing seat 1 is usually an aluminum seat, and its surface needs to be coated with thermal conductive silicone grease to dissipate the heat of the power part of the circuit board. By arranging a pad 12 on the fixing seat 1, it can be used to support the first circuit board 5, so that the first circuit board 5 is lifted by the pad 12 during assembly, and the bottom surface of the first circuit board 5 abuts against the surface of the pad 12, thereby avoiding direct contact between the first circuit board 5 and the surface of the fixing seat 1, and avoiding the thermal conductive silicone grease from overflowing and squeezing out, resulting in a short circuit between the electrical copper foil on the circuit board and the aluminum fixing seat 1.

[0073] Furthermore, the cushion block 12 is disposed on the support column 11 and is located at one end of the support column 11 close to the fixing seat 1 .

[0074] like Figure 2 As shown, the pads 12 can be arranged at the root of the support column 11 , and the horizontal heights of all the pads 12 are consistent to ensure the horizontality of the installation of the first circuit board 5 .

[0075] The assembly process of the embodiment of the present application is as follows:

[0076] Place the first circuit board 5 through the support column 11 and onto the pad 12 on the fixing seat 1, and fix the first circuit board 5 to the fixing seat 1 with screws; put the mounting sleeve 2 on the support column 11, insert the positioning portion 24 of the mounting sleeve 2 into the positioning hole on the first circuit board 5, so that the lower end of the main body 21 of the mounting sleeve 2 abuts against the first circuit board 5; install the second circuit board 6 on the upper end of the support column 11, let the protruding portion of the mounting sleeve 2 pass through the mounting hole on the second circuit board 6, so that the second circuit board 6 is placed on the top of the support column 11, and the protruding portion protrudes from the surface of the second circuit board 6; use the pad The sheet 3 presses the protruding part, and the screw 4 passes through the gasket 3 and the second mounting plate and is screwed into the support column 11, so that the second circuit board 6 is connected and fixed to the support column 11. At this time, the mounting sleeve 2 is pressed downward by the pressure of the gasket 3, so that the first circuit board 5 can obtain a tightening force in this area without installing screws; at the same time, the mounting sleeve 2 is made of elastic plastic, and the screw 4 and the gasket 3 will flatten the protruding part protruding from the surface of the second circuit board 6 when locked, so that the second circuit board 6 is also locked, and finally the force on the entire circuit board is in a balanced state.

[0077] The circuit board mounting structure described in the embodiment of the present application is not limited to use in a steering controller. According to different actual usage scenarios, the shape of the circuit board, the number of support columns 11, etc. can be flexibly adjusted.
