Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steering switch, and particularly relates to an automobile steering combination switch and an automobile. BACKGROUND

[0002] At present, the handle function of the Hall sensor of the automobile steering combination switch can be realized by the relative position change between the magnet and the sensor to identify different gears. That is, during the handle swing, the position change of the magnet relative to the Hall sensor is detected by the Hall sensor to identify different gears.

[0003] In the related art, the swing range of the handle head of the automobile steering combination switch needs to have enough space to ensure the movement displacement of the magnet. The current product size of the automobile steering combination switch allows the distance from the handle rotating shaft axis to the steering column axis to be set large enough, for example, the distance therebetween can reach 90 mm. In the case that the distance is enough, a conventional swing-type magnet can be arranged. However, when the distance from the handle rotating shaft axis to the steering column axis is insufficient, for example, the distance therebetween is only about 41 mm, a conventional swing-type magnet cannot be arranged.

[0004] Therefore, how to avoid the problem that the swing-type magnet cannot be arranged due to insufficient swing space of the handle head is a technical problem to be solved by the person skilled in the art at present. CONTENT OF THE INVENTION

Through the rotation of the magnet, the different gears of the handle assembly are associated with the rotation angle of the magnet in the limited space, so as to realize gear detection, and solve the problem that the swing type magnet cannot be arranged due to insufficient swing space of the handle head.

[0051] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0053] See also Figure 1 and Figure 2 The automobile steering combination switch provided in the embodiment of the present application includes an upper cover 10, a bracket 30 with a magnet 20 and a handle assembly 40.

[0054] Among them, the bracket 30 is rotatably connected to the upper cover 10, and the bracket 30 is used to drive the magnet 20 to rotate; a driving pin 421 is provided on the handle assembly 40, and the driving pin 421 cooperates with the bracket 30. The handle assembly 40 is used to drive the driving pin 421 to rotate relative to the upper cover 10, and the driving pin 421 pushes the bracket 30 to rotate. The handle assembly 40 includes a handle rotating pin 41, and the magnet 20 is located between the handle rotating pin 41 and the driving pin 421.

[0055] In addition, the vehicle steering combination switch also includes a Hall sensor, which is communicatively connected to the PCBA80 (Printed Circuit Board Assembly). The Hall sensor is disposed toward the magnet 20 and is used to sense the rotation of the magnet 20 to identify different gear positions.

[0056] In this way, the swing of the handle assembly 40 is transmitted to the bracket 30 through the driving pin 421 on the handle assembly 40, so that the bracket 30 drives the magnet 20 to rotate. Through the rotation of the magnet 20, the different gears of the handle assembly 40 are correspondingly associated with the rotation angle of the magnet 20 in a limited space, so that gear detection is realized, and the problem that the swing type magnet 20 cannot be arranged due to insufficient swing space of the handle head is solved.

[0057] Please refer to Figure 3 Since the magnet 20 is located between the handle rotating pin 41 and the driving pin 421, according to the rotation relationship: the rotation angle of the bracket 30 / the rotation angle of the handle assembly 40 = the rotation radius r1 of the driving pin 421 / the rotation radius r2 of the bracket 30. Since the ratio of the rotation radius r1 of the driving pin 421 and the rotation radius r2 of the bracket 30 is greater than 1, the ratio of the rotation angle of the bracket 30 and the rotation angle of the handle assembly 40 is also greater than 1, that is, the rotation angle of the handle assembly 40 is amplified to the rotation angle of the bracket 30 through the ratio of the distance between the driving pin 421 and the handle rotating pin 41 (the rotation radius of the driving pin 421) and the rotation radius of the bracket 30, so as to amplify the data of the rotation amount of the magnet 20 sensed by the Hall sensor, and improve the stability of gear sensing.

[0058] In order to amplify the rotation angle of the handle assembly 40 to the rotation angle of the bracket 30, the ratio of the distance between the axis of the driving pin 421 and the axis of the handle rotating pin 41 to the distance between the axis of the driving pin 421 and the rotation axis of the bracket 30 is in the range of 2:1~3:1.

[0059] In some embodiments, the rotation angle of the bracket 30 / the rotation angle of the handle assembly 40 = the rotation radius r1 of the driving pin 421 / the rotation radius r2 of the bracket 30 = 22.685 / 9.185≈2.47, that is, the angle amplification ratio is 2.47.

[0060] In this way, the rotation angle of the handle assembly 40 is amplified to the rotation angle of the bracket 30 through the ratio of the rotation radius of the driving pin 421 and the rotation radius of the bracket 30, so as to amplify the data of the rotation amount of the magnet 20 sensed by the Hall sensor, and improve the stability of gear sensing.

[0061] In order to facilitate the cooperation between the driving pin 421 and the bracket 30, the bracket 30 is provided with a driving groove 321, and the upper cover 10 is provided with a through hole 11. The driving pin 421 passes through the through hole 11 and extends into the driving groove 321, so that the driving pin 421 is driven by the handle assembly 40 to drive the bracket 30 to rotate.

[0062] It can be understood that the driving pin 421 extends into the driving slot 321 of the bracket 30 through the through hole 11 of the upper cover 10, and as the handle assembly 40 is operated, the handle assembly 40 drives the driving pin 421 to rotate, the driving pin 421 drives the bracket 30 to rotate relative to the upper cover 10, so as to realize the rotation of the magnet 20.

[0063] In some embodiments, the bracket 30 includes a bracket body 31 and two oppositely arranged driving bodies 32. The bracket body 31 is provided with a mounting slot for mounting the magnet 20, and the driving slot 321 is arranged between the two driving bodies 32. The two driving bodies 32 are connected to the bracket body 31 by a connecting body, and the two driving bodies 32 are spaced apart and arranged downward to form the driving slot 321 for accommodating the driving pin 421 between the two driving bodies 32.

[0064] Please refer to Figure 4 In order to facilitate the assembly of the bracket 30, the upper cover 10 is provided with a first rotating slot 12 and a second rotating slot 13. The second rotating slot 13 is arranged outside the first rotating slot 12. The first rotating slot 12 is a circular slot, and the second rotating slot 13 is an arc-shaped slot. The bracket body 31 is rotatably mounted in the first rotating slot 12 by a bearing, and the two driving bodies 32 are rotatably arranged in the second rotating slot 13. The through hole 11 is arranged in the second rotating slot 13.

[0065] In some embodiments, the handle assembly 40 further includes a handle shell 42 connected with the handle rotating pin 41. The handle shell 42 has a cavity for accommodating the top pin 43, and the driving pin 421 is integrally formed with the handle shell 42.

[0066] Specifically, the driving pin 421 extends upward as a structure extending upward from the top of the handle shell 42, for extending upward through the through hole 11 of the upper cover 10 and into the space between the two driving bodies 32 of the second rotating slot 13. As the handle assembly 40 is operated, the handle assembly 40 drives the driving pin 421 to rotate, the driving pin 421 drives the bracket 30 to rotate relative to the upper cover 10, so as to realize the rotation of the magnet 20.

[0067] In some embodiments, the handle assembly 40 further includes a top pin 43 arranged inside the handle shell 42, and the automobile steering combination switch further includes a gear curve block 44. The top pin 43 is used for swinging relative to the gear curve block 44 to switch gears.

[0068] In the embodiment, the gear cam block 44 has a high gear, a low gear and a zero gear, and the zero gear is between the high gear and the low gear. The handle assembly 40 is pushed by the internal tappet 43 (cam tappet) structure after operation, and automatically returns to the zero gear of the gear cam block 44. Since the gear cam block 44 is a V-shaped circular arc at the zero gear, the spring on the tappet 43 drives the handle assembly 40 to return to the bottom of the V-shaped circular arc. Due to inertia, the handle assembly 40 does not stop immediately when it reaches the zero gear, but overshoots the zero gear to the reverse position, and then moves towards the zero gear again, and again overshoots the zero gear. Thus, the handle assembly 40 will have multiple back-and-forth movements at the bottom of the V-shaped circular arc, causing the zero gear to vibrate until the return energy is exhausted due to friction.

[0069] The return vibration will cause two problems: first, the reverse gear signal appears, and second, the vibration noise.

[0070] Please refer to Figure 5 , Figure 6 and Figure 7 To solve the above problems, the handle assembly 40 is provided with a rack 50 on the side close to the gear cam block 44, and the automobile steering combination switch further comprises a damping gear 60 rotatably connected to the gear cam block 44. The damping gear 60 is engaged with the rack 50, and the damping gear 60 is used to generate damping when the tappet 43 returns from the first position to the second position of the gear cam block 44, so as to reduce the return speed of the tappet 43.

[0071] The first position can be the high gear, and the second position can be the zero gear. That is, the rack 50 is added to the head of the handle assembly 40, and the rack 50 is engaged with a damping gear 60. During the process that the tappet 43 returns from the high gear to the zero gear of the gear cam block 44, the kinetic energy of the tappet 43 when it returns from the high gear to the zero gear of the gear cam block 44 is consumed by the rotation damping of the damping gear 60 (the tappet 43 slides from the high gear to the low gear of the gear cam block at a relatively high speed, and the sliding speed is reduced by the resistance of the damping gear 60 through the linkage of the rack 50 and the damping gear 60), so as to reduce the return speed of the tappet 43 (increase the damping of the tappet 43 when it returns to the zero gear). Thus, the back-and-forth vibration of the tappet 43 when it returns to the zero gear is avoided.

[0072] In this way, by eliminating the return vibration, the reverse gear signal when the tappet 43 returns to the zero gear is avoided, the false signal of the product on the whole vehicle is prevented, the vibration noise when the tappet 43 returns to the zero gear is avoided, and the NVH performance of the product is better. The NVH performance is the comprehensive performance of noise (Noise), vibration (Vibration) and harshness (Harshness) generated by the automobile during driving, which directly affects the comfort of driving and riding.

[0073] It should be noted that the radian and time length of the zero position jitter depend on the size of the circular arc at the zero position of the V-shaped surface, the angle slope of the two sides and the damping of the motion system. If the angle of the V-shaped surface is limited alone, the top pin 43 will hit the reverse side of the V-shaped surface during the return, and the return noise will occur, which cannot meet the customer's NVH demand. Therefore, the damping of the return process of the top pin 43 is increased to reduce the speed of the top pin 43 returning to zero, so as to avoid the back and forth jitter of the top pin 43 returning to zero.

[0074] The automobile steering combination switch further comprises a switch housing 70, the switch housing 70 comprises a housing body 71 and two clamp elastic arms 72, and a slot 73 is arranged between the two clamp elastic arms 72 and the housing body 71.

[0075] It should be noted that, please see Figures 8 to 12 When the automobile steering combination switch is assembled to the steering column, the fastening clamp on the switch housing 70 needs to be tightly held on the column. The clamp on such a housing is made of plastic material, and because the slot 73 needs to be arranged between the clamp elastic arm 72 and the housing body 71 (to make a cantilever to realize elastic deformation), the axial connection strength of the clamp and the housing body 71 is weakened. When subjected to a larger external force, due to the existence of the slot 73, the deformation and displacement between the housing body 71 and the clamp elastic arm 72 occur, and the switch housing 70 is easily detached from the column. Therefore, the connecting rib plate 711 is additionally arranged on the housing body 71 to enhance the connection strength between the clamp elastic arm 72 and the housing body 71, so that the clamp elastic arm 72 is directly associated with the housing body 71, and the axial deformation and detachment of the housing body 71 are prevented.

[0076] Specifically, the connecting rib plate 711 is arranged on the housing body 71 and located between the two clamp elastic arms 72, and the switch housing 70 further comprises a clamp connecting piece 74, the clamp connecting piece 74 passes through the two clamp elastic arms 72 and the connecting rib plate 711 to connect the two clamp elastic arms 72 and the housing body 71. Of course, the clamp connecting piece 74 is specifically a clamp bolt.

[0077] In this way, the connecting rib plate 711 is arranged between the two clamp elastic arms 72, and the through hole 11 on the connecting rib plate 711 cooperates with the clamp bolt to establish the connection between the housing body 71 and the clamp elastic arm 72 in the up-down direction.

[0078] It can be understood that due to the existence of the slot 73 of the clamp elastic arm 72, when the handle is subjected to a large up-down external force, the shell body 71 will be separated from the bottom clamp elastic arm 72 or close to the bottom, and the slot 73 will be expanded or reduced. After the addition of the connecting rib plate 711, the clamp elastic arm 72 can pull or push the shell body 71 which is about to be displaced through the connecting rib plate 711, thereby avoiding the skewing of the switch shell 70, ensuring the correct assembly posture of the switch shell 70 on the pipe column, avoiding various rotating abnormal noises caused by the skewing of the switch shell 70, and solving the problems of deformation of the plastic clamp shell at the slot 73, skewing of the shell assembly posture, and disengagement of the buckle 75.

[0079] Please refer to Figure 13 and Figure 14 , the switch shell 70 further comprises a buckle 75, the buckle 75 is provided with a clamping protrusion 751, the clamping protrusion 751 is used for clamping with a clamping groove on the steering column, and the buckle 75 is further provided with a stop rib 752, the stop rib 752 is arranged on the side of the buckle 75 away from the clamping protrusion 751, and the stop rib 752 is used for abutting against the clamp elastic arm 72 and the connecting rib plate 711 to prevent the buckle 75 from disengaging from the steering column.

[0080] When the switch shell 70 is subjected to a large external force (the external force is transmitted into the switch shell 70 through the handle assembly 40), the buckle 75 will have a tendency to deform outward and disengage. By adding the stop rib 752 to the back of the buckle 75, the deformation and disengagement of the buckle 75 are prevented.

[0081] Please refer to Figure 15 and Figure 16 When the switch shell 70 is subjected to a large external force (the external force is transmitted into the switch shell 70 through the handle assembly 40), the buckle 75 will have a tendency to deform outward and disengage. By adding the stop rib 752 to the back of the buckle 75, the deformation and disengagement of the buckle 75 are prevented.

[0082] In summary, the automobile steering combination switch provided by the application realizes the Hall sensor induction of the handle stop position through the rotary motion of the magnet 20, realizes the arrangement of the stop position function structure in a limited small motion space, and solves the problem that the swing type magnet 20 cannot be arranged due to insufficient swing space of the handle head. At the same time, by adding the rack 50 to the handle head and the damping gear 60 matched with the rack 50, the shaking of the handle zero position is eliminated, and the reverse stop position signal and shaking noise are avoided. In addition, by adding the connecting rib position in the elastic arm 72 of the plastic clamp of the shell and adding the stop rib 752 at the back of the buckle 75, the assembly firmness of the shell is obviously improved, and the rotation abnormal noise or other function problems caused by the inclination of the product assembly posture due to external force are avoided.
