Technical Field
[0001] This utility model relates to the field of automotive technology, specifically to a connection structure and a drive-by-wire automotive steering control module. Background Technology
[0002] Steer-by-wire is an advanced automotive steering technology that eliminates the physical mechanical connection between the steering wheel and the wheels (such as the steering column and steering linkage), replacing it with electronic signals and an electronically controlled actuator system.
[0003] In the prior art, Chinese utility model with announcement number CN220163979U discloses a steer-by-wire bracket, which uses two clamps to clamp the conductor wire inward to fix it and prevent the conductor wire from shifting or getting tangled.
[0004] However, currently, the control cable for the brushless motor in traditional steer-by-wire control modules needs to be plugged in and unplugged separately during installation. Therefore, a certain length of cable needs to be reserved. After installation, the cable is not only exposed and prone to tangling, but also occupies a significant amount of space, which is detrimental to the overall installation and placement of the steer-by-wire module. To address these issues, this invention proposes a connection structure and a steer-by-wire automotive control module. Utility Model Content
[0005] The purpose of this invention is to provide a connection structure and a drive-by-wire vehicle steering control module to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection structure, comprising: A connecting ring, the edge of which is fixed with an arc-shaped flange, the surface of which is provided with a guide groove concentric with the connecting ring, the inner cavity of which is slidably installed with a matching limiting slider, a top block is provided in the middle of the arc-shaped flange, and a docking socket is provided on the edge of the connecting ring and fixed therewith, and a busbar is provided on the docking socket. The brushless motor has a flange fixed at the edge of its flange, which is fixedly connected to the limit slider by bolts. The side of the brushless motor is provided with a docking plug fixed thereto. When the brushless motor rotates, the docking plug is electrically connected to the docking socket. The flange has a helical tooth groove in the middle that corresponds to the top block.
[0007] Preferably, both the arc-shaped flange and the flange flange are provided in two sets, and are distributed in a ring array around the axis of the connecting ring.
[0008] Preferably, the cross-sections of the guide groove and the limiting slider are both set to an "I" shape, and the surface of the limiting slider is provided with a threaded slot, and the bolts on the flange are threaded into the inner cavity of the threaded slot.

[0010] Preferably, a receiving groove is formed in the middle of the surface of the arc-shaped flange, the top block is located in the inner cavity of the receiving groove, and a helical tooth block is fixed on the surface of the top block. The helical tooth block is adapted to the helical tooth groove, and the central angle of the helical tooth groove is greater than the central angle of the helical tooth block.
[0011] Preferably, a limiting buckle is fixed on the side of the top block, and a limiting groove communicating with the inner cavity of the storage slot is provided on the side of the arc-shaped flange, and the limiting buckle is slidably engaged in the limiting groove.
[0012] Preferably, a groove is provided in the middle of the bottom of the storage slot, and a thrust spring is provided in the groove, with the upper end of the thrust spring abutting against the top block.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example 1, please refer to Figures 1-6 This utility model provides a technical solution: a connection structure, including: a connecting ring 1 and a brushless motor 2.
[0019] Specifically, an arc-shaped flange 11 is fixed to the edge of the connecting ring 1. A guide groove 12 concentric with the connecting ring 1 is opened on the surface of the arc-shaped flange 11. A limiting slider 13 adapted to it is slidably installed in the inner cavity of the guide groove 12. Since the guide groove 12 is concentric with the connecting ring 1, the sliding path of the limiting slider 13 in the inner cavity of the guide groove 12 is around the center of the connecting ring 1. A top block 16 is provided in the middle of the arc-shaped flange 11. A docking socket 14 fixed to it is provided on the edge of the connecting ring 1. A busbar 15 is provided on the docking socket 14. The surface of the docking socket 14 is arc-shaped, and the axis of the arc-shaped surface coincides with the axis of the connecting ring 1. The busbar 15 is completely housed in the protective frame and cannot be bent or deformed. Secondly, a flange 21 is fixed to the edge of the flange of the brushless motor 2. The flange of the brushless motor 2 corresponds to the connecting ring 1, and the flange 21 corresponds to the arc-shaped flange 11. The flange 21 is fixedly connected to the limiting slider 13 by bolts. Therefore, the brushless motor 2 can be installed on the surface of the connecting ring 1. A docking plug 22 is provided on the side of the brushless motor 2 and fixed thereto. When the brushless motor 2 rotates, the docking plug 22 is electrically connected to the docking socket 14. Figure 2As shown, when the brushless motor 2 is connected to the connecting ring 1, since the limiting slider 13 can slide in the inner cavity of the guide groove 12, the brushless motor 2 can also rotate around its own axis at a certain angle. By rotating the brushless motor 2, the docking plug 22 and the docking socket 14 can be plugged in and engaged. A helical tooth groove 23 corresponding to the top block 16 is provided in the middle of the flange flange 21. The helical tooth groove 23 is mainly used to prevent the brushless motor 2 from rotating in the opposite direction after it rotates, thereby realizing the rotational positioning of the brushless motor 2. Finally, the bolts are tightened further to achieve stable installation of the brushless motor 2.
[0020] To guide the rotation of the brushless motor 2, both the arc-shaped flange 11 and the flange flange 21 of this application are provided in two sets, and are distributed in a circular array around the axis of the connecting ring 1, such as... Figure 3 and Figure 4 As shown, there are four guide grooves 12 and four limiting sliders 13, which are located at the two ends of the two sets of arc-shaped flanges 11, respectively. This ensures that the connection between the brushless motor 2 and the connecting ring 1 is more stable, so that after the brushless motor 2 and the connecting ring 1 are initially connected, the brushless motor 2 can only rotate and move through the limiting sliders 13, without tilting or shifting.
[0021] In order to allow the bolts on the flange flange 21 to be inserted and connected, the cross sections of the guide groove 12 and the limiting slider 13 of this application are both set to "I" shape. Therefore, the limiting slider 13 can only slide in the inner cavity of the guide groove 12 and will not separate from it. A threaded slot 131 is provided on the surface of the limiting slider 13. The bolts on the flange flange 21 are inserted into the inner cavity of the threaded slot 131 through the thread, thereby ensuring that after the bolts on the flange flange 21 are tightened, the flange flange 21 can be locked and fixed with the limiting slider 13.
[0022] For the installation of the mating socket 14, this application also includes a socket bracket 141 fixed to the mating socket 14, and the socket bracket 141 is fixed to the side of the connecting ring 1 by bolts, such as... Figure 4 As shown, the socket bracket 141 is mainly used for the installation and positioning of the docking socket 14. The socket bracket 141 is L-shaped, which can avoid motion interference to the rotation of the brushless motor 2.
[0023] To prevent the brushless motor 2 from rotating in the opposite direction and causing the connector 22 to separate from the socket 14, this application also includes a receiving groove 17 formed in the middle of the surface of the arc-shaped flange 11. A top block 16 is located in the inner cavity of the receiving groove 17. The top block 16 can move up and down along the depth direction of the receiving groove 17, so as to be completely received into the inner cavity of the receiving groove 17 or protrude to the upper side of the opening of the receiving groove 17. A helical tooth block 161 is fixed on the surface of the top block 16. The helical tooth block 161 is adapted to the helical tooth groove 23. When the top block 16 is completely received into the inner cavity of the receiving groove 17, the helical tooth block 161 and the helical tooth groove 23 are in a separated state, and the openings of the helical tooth block 161 and the helical tooth groove 23 are both facing the rotation direction of the brushless motor 2. The direction of rotation is reversed. Therefore, when the brushless motor 2 rotates in the forward direction, the engagement between the helical tooth block 161 and the helical tooth groove 23 will not hinder the rotation of the brushless motor 2. Only when the brushless motor 2 rotates in the reverse direction will the engagement between the helical tooth block 161 and the helical tooth groove 23 hinder the rotation of the brushless motor 2. In other words, the engagement between the helical tooth block 161 and the helical tooth groove 23 can form a structure similar to a one-way ratchet, thereby preventing the docking plug 22 from disengaging from the docking socket 14 due to the reverse rotation of the brushless motor 2. In addition, the central angle of the helical tooth groove 23 is larger than the central angle of the helical tooth block 161. Therefore, during the rotation of the brushless motor 2, the helical tooth block 161 can always maintain mutual engagement with the helical tooth groove 23.
[0024] To prevent the top block 16 from completely separating from the storage groove 17, this application also includes a limiting buckle 162 fixed on the side of the top block 16, and a limiting groove 171 communicating with the inner cavity of the storage groove 17 on the side of the arc-shaped flange 11. The limiting buckle 162 is slidably engaged in the limiting groove 171. Figure 6 As shown, the engagement of the limiting buckle 162 and the limiting slot 171 can limit the vertical sliding of the top block 16, preventing the top block 16 from completely separating from the storage slot 17.
[0025] In order to provide thrust to the top block 16, this application also has a groove in the middle of the bottom of the storage groove 17, and a thrust spring 18 is provided in the groove. The upper end of the thrust spring 18 abuts against the top block 16. The thrust spring 18 is provided to provide thrust to the top block 16, so that the top block 16 always tends to move away from the bottom of the storage groove 17, thereby ensuring that the helical tooth block 161 always maintains mutual engagement with the helical tooth groove 23.
[0026] This application also discloses a drive-by-wire vehicle steering control module, including the connection structure described above.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
