Description

Technical Field

[0001] This utility model relates to the field of automotive design and manufacturing technology, specifically to a steering system and a vehicle. Background Technology

[0002] The steering column is part of the car's steering system, primarily responsible for converting the rotational motion of the steering wheel into the steering motion of the wheels, thereby controlling the vehicle's direction. When the vehicle is turned off, the steering wheel is generally restricted from turning, i.e., it is locked. With the upgrading of vehicle configurations and the increasing prevalence of keyless start features, existing steering wheel locking structures are no longer sufficient to meet the requirements. Furthermore, existing steering wheel locking structures require mechanical locking with an ignition lock, which is relatively large and its placement angle and orientation must meet ergonomic requirements, resulting in significant space requirements and installation challenges.

[0003] Therefore, there is a need to provide an improved steering system to overcome or reduce at least some of the disadvantages present in the prior art. Utility Model Content

[0029] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is by no means a limitation of the present invention or its applications or uses. Furthermore, the dimensions and proportions of the components in the drawings are merely schematic and do not strictly correspond to actual products.

[0030] This utility model provides a steering system 100, such as Figure 1 , Figure 6 , Figure 7 and Figure 9 As shown, the steering system 100 includes a steering column 101 and a steering wheel locking structure 102, wherein the steering wheel locking structure 102 is detachably attached to the steering column 101; and the steering wheel locking structure 102 is configured to switch between a locked state and an unlocked state, and the steering wheel locking structure 102 includes a mounting sleeve 120 and a locking mechanism 130; the steering column 101 passes through the mounting sleeve 120 in the axial direction, the mounting sleeve 120 has a first opening 121 in the radial direction, and the locking mechanism 130 is disposed at the first opening 121 on the outer peripheral wall of the mounting sleeve 120; in the locked state, the locking mechanism 130 engages with a limiting hole 1110 on the steering column 101 to fix and lock the steering column 101; in the unlocked state, the locking mechanism 130 disengages from the limiting hole 1110 on the steering column 101 to release the steering column 101.

[0031] The steering system 100 of this embodiment includes a steering column 101 and a steering wheel locking structure 102. The steering wheel locking structure 102 is detachably attached to the steering column 101, meaning it is a separate structure. The steering column 101 and steering wheel locking structure 102 are separate structures. This allows the steering wheel locking structure 102 to be used with different steering columns 101, improving scalability. In other words, the steering wheel locking structure 102 of this embodiment is completely independent of the steering column 101, enabling it to be used with steering columns 101 on different vehicle models, thus exhibiting high versatility. This facilitates platform-based vehicle design and reduces costs. By configuring the steering wheel locking structure 102 to include a mounting sleeve 120 and a locking mechanism 130, the steering wheel locking structure 102 can be arranged with a simple structural design and small structural volume. The small structural volume eliminates the need to consider ergonomics and reduces the space requirements for arrangement. Simultaneously, the simple structure makes arrangement easy and reduces the difficulty of arrangement. By having the steering column 101 pass through the mounting sleeve 120 in the axial direction, and the mounting sleeve 120 having a first opening 121 in the radial direction, the locking mechanism 130 is disposed at the first opening 121 on the outer peripheral wall of the mounting sleeve 120. Figure 7 As shown, in the locked state, the locking mechanism 130 engages with the limiting hole 1110 on the steering column 101 to fix and lock the steering column 101, and as... Figure 9As shown, in the unlocked state, the locking mechanism 130 disengages from the limiting hole 1110 on the steering column 101 to release the steering column 101, thereby enabling the steering wheel locking structure 102 to switch between the locked and unlocked states, and thus achieve the purpose of locking or releasing the steering wheel.

[0032] like Figure 10 As shown, the present invention also provides a vehicle 200, which includes the aforementioned steering system 100. The steering system 100 of this embodiment can be used in all vehicles employing steer-by-wire technology.

[0033] The composition of the steering system 100 of this utility model embodiment will be described in more detail below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 6 , Figure 7 and Figure 9 As shown, the steering system 100 includes a steering column 101 and a steering wheel locking structure 102, wherein the steering wheel locking structure 102 is detachably attached to the steering column 101. The steering wheel locking structure 102 is configured to switch between a locked state and an unlocked state and includes a mounting sleeve 120 and a locking mechanism 130. Figure 7 As shown, the steering column 101 passes through the mounting sleeve 120 in the axial direction, and the mounting sleeve 120 has a first opening 121 in the radial direction on its top wall. A locking mechanism 130 is provided at the top portion of the outer peripheral wall of the mounting sleeve 120 at the first opening 121. Figure 7 In the middle, the steering wheel locking structure 102 is in the locked state, and the locking mechanism 130 engages with the limiting hole 1110 on the steering column 101 to fix and lock the steering column 101. At this time, the steering wheel cannot be rotated. Figure 9 In the middle, the steering wheel locking structure 102 is in the unlocked state, and the locking mechanism 130 disengages from the limiting hole 1110 on the steering column 101 to release the steering column 101. At this time, the steering wheel can be rotated.

[0035] In some embodiments, the steering column 101 may include a steering column body 113 and a limiting sleeve 111. The limiting sleeve 111 is fixed to the outer peripheral wall of the steering column body 113, and a limiting hole 1110 is formed on the limiting sleeve 1111. The steering column body 113 may be the steering shaft of the steering column 101. One end of the steering shaft is connected to the steering wheel and can rotate with the steering wheel. The specific structure of the steering column 101 itself can adopt any structure in the prior art, and is not limited here. The connection structure between the steering column 101 and the steering wheel can adopt any structure in the prior art, and is not limited here. When the limiting sleeve 111 is provided, the state switching of the steering system 100 is mainly achieved through the cooperation of the locking mechanism 130 with the limiting sleeve 111, especially the limiting hole 1110 on the limiting sleeve 111. The limiting sleeve 111 can be fixed to the outside of the steering column body 113 by means of welding, for example, or the limiting sleeve 111 can be integrated into the steering column body 113. By setting the limiting sleeve 111, the locking mechanism 130 and the steering column 101 can be stably engaged in the locked state without drilling holes in the steering column body 113, which can improve the generalization and platformization of components and reduce the cost of components and development expenses.

[0036] The number of limiting holes 1110 can be one or more. Figure 3 In the embodiment shown, the number of limiting holes 1110 is one. Figure 3 As shown, the limiting hole 1110 can be an oblong hole. By setting oblong holes of different sizes, such as oblong holes of different lengths, different locking angle ranges of the steering wheel can be achieved. It can be understood that, given a fixed machining dimension of the limiting hole 1110, the actual application dimension of the limiting hole 1110 can also be adjusted by setting additional adjustment structures. For the adjustment structure, any existing structure capable of adjusting the hole diameter can be used, and no limitation is made here. The number of limiting holes 1110 can be multiple, such as two or more, such as two, three, or four. When there are multiple limiting holes 1110, these multiple limiting holes 1110 can be evenly spaced circumferentially around the limiting sleeve 111. By setting multiple limiting holes 1110, the steering wheel can be locked at different positions.

[0037] Figure 1 and Figure 2 In addition to the steering column 101 and the steering wheel locking structure 102, the diagram also shows components associated with the steering column 101, such as the mounting structure of the steering column 101 and the power structure. These structures are all existing structures and will not be described in detail here. Furthermore, the specific configuration of these structures can adopt any structure in the prior art and will not be limited here.

[0038] refer to Figures 2 to 4 The mounting sleeve 120 has a second opening 122 in the axial direction, through which the steering column 101 passes. A first mounting structure 123 is formed around the second opening 122 in the mounting sleeve 120. A second mounting structure 112 is formed on the side of the steering column 101 facing the second opening 122. The first mounting structure 123 and the second mounting structure 112 are adapted to each other, thereby achieving a detachable attachment between the steering wheel locking structure 102 and the steering column 101. The mounting seat 110 of the steering column 101 refers to the component associated with the steering column 101 and having a relatively stable positional relationship. It can be a separate component or integrated into other components associated with the steering column 101; this is not limited here.

[0039] like Figure 4 and Figure 7 As shown, the mounting sleeve 120 has a closed end on the left side and an open second opening 122 on the right side. One end of the steering column 101 passes through the second opening 122 into the mounting sleeve 120. Figure 4 As shown, the mounting sleeve 120 extends outward in the circumferential direction around the second opening 122 to form a first mounting structure 123. It can be understood that the mounting sleeve 120 may also extend outward in a portion around the second opening 122 to form the first mounting structure 123. For example... Figure 2 and Figure 3 As shown, the mounting base 110 of the steering column 101 has a second mounting structure 112 formed on the side facing the second opening 122. The first mounting structure 123 and the second mounting structure 112 are adapted to achieve a detachable attachment between the steering wheel locking structure 102 and the steering column 101.

[0040] The first mounting structure 123 can be integrated into the mounting sleeve 120, or it can be a separate structure from the mounting sleeve 120. Preferably, the first mounting structure 123 is integrated into the mounting sleeve 120 and is formed in one piece with the mounting sleeve 120, which can simplify the installation steps, etc.

[0041] The second mounting structure 112 can be integrated into the mounting base 110, or it can be a separate structure from the mounting base 110. Preferably, the second mounting structure 112 is integrated into the mounting base 110, which can ensure the stability of the second mounting structure 112.

[0042] The first mounting structure 123 and the second mounting structure 112 can be structures that are fixed by fasteners such as screws, or they can be snap-fit ​​structures, etc.

[0043] In some embodiments, such as Figure 3 and Figure 4As shown, the first mounting structure 123 is a mounting flange 1231 with a first mounting hole 1232, and the second mounting structure 112 is a mounting post 1121 with a second mounting hole 1122. The first mounting hole 1232 and the second mounting hole 1122 are fixed together by a fastener (not shown in the figure). By configuring the first mounting structure 123 as a mounting flange 1231 with the first mounting hole 1232 and the second mounting structure 112 as a mounting post 1121 with the second mounting hole 1122, and connecting them by bolting with a flange, a detachable and secure attachment of the steering column 101 and the steering wheel locking structure 102 can be easily achieved using fasteners such as screws.

[0044] Continue to refer to Figure 3 There are three mounting posts 1121, and the three mounting posts 1121 are arranged in a triangle. Each mounting post 1121 has a second mounting hole 1122. Correspondingly, as... Figure 4 As shown, three first mounting holes 1232 are evenly spaced on the mounting flange 1231. By providing three mounting posts 1121, the stable attachment of the steering column 101 and the steering wheel locking structure 102 can be further ensured. It is understood that other numbers of mounting posts 1121 can also be provided; the three mounting posts 1121 can also be distributed in other shapes; each mounting post 1121 can also have more than one second mounting hole 1122; correspondingly, the shape of the mounting flange 1231, the position and number of the first mounting holes 1232, etc., can also be adjusted.

[0045] The locking mechanism 130 can be an electromagnetically controlled telescopic bolt mechanism. For example... Figures 5 to 8 As shown, the locking mechanism 130 includes a housing 131, a telescopic latch assembly 132, and a coil 133. At least a portion of the telescopic latch assembly 132 and the coil 133 are disposed within the housing 131, and the coil 133 is sleeved on the telescopic latch assembly 132. In the locked state, the coil 133 is de-energized, causing the telescopic latch assembly 132 to extend and engage with the limiting hole 1110. In the unlocked state, the coil 133 is energized, causing the telescopic latch assembly 132 to retract and disengage from the limiting hole 1110. The coil 133 can be energized to generate an electromagnetic field, which acts on the telescopic latch assembly 132 to perform telescopic movement. When the vehicle is turned off and power is cut off, the coil 133 is de-energized, and the telescopic latch assembly 132 is in the extended state to fix the steering column 101, preventing the steering column 101 from rotating and thus locking the steering wheel. When the vehicle is ignited and powered on, the coil 133 is energized, causing the telescopic latch assembly 132 to retract and release the steering column 101, allowing the steering column 101 to rotate normally, thereby enabling the steering wheel to rotate normally.

[0046] Continue to refer to Figures 5 to 9The telescopic locking tongue assembly 132 may include a fixed iron core 1321, an elastic element 1322, and a moving iron core 1323, which are stacked sequentially in the radial direction of the mounting sleeve 120. In the locked state, the elastic element 1322 extends the moving iron core 1323 towards the side closer to the steering column 101 until the moving iron core 1323 engages with the limiting hole 1110. In the unlocked state, the moving iron core 1323 compresses the elastic element 1322 and retracts towards the side away from the steering column 101 until the moving iron core 1323 disengages from the limiting hole 1110. The radial direction of the mounting sleeve 120 is also the radial direction of the steering column 101. The locking mechanism 130 of this embodiment is a split structure, which can improve the generalization and platformization of components, and reduce component costs and development expenses.

[0047] The housing 131 protects the telescopic latch assembly 132 and the coil 133. For example... Figure 5 and Figure 7 As shown, the housing 131 may include a housing body 1311 and an end cap 1312. The housing body 1311 has a through structure from top to bottom. The end cap 1312 is disposed at one end opening of the housing body 1311 to close the housing body 1311. The other end opening of the housing 131 is used for the moving iron core 1323 to pass through.

[0048] Both the fixed iron core 1321 and the moving iron core 1323 are made of magnetically conductive materials, such as iron alloys. In this embodiment, the fixed iron core 1321 is fixedly installed inside the housing 131, and the moving iron core 1323 is capable of telescoping, with the telescoping direction being the radial direction of the mounting sleeve 120. An elastic element 1322 is sandwiched between the fixed iron core 1321 and the moving iron core 1323. The elastic element 1322 can be a spring, an elastic rubber pad, a spring sheet, etc., but is typically a spring.

[0049] like Figure 9 As shown, when the vehicle is powered on, the coil 133 is energized, and the fixed iron core 1321 and the moving iron core 1323 form an electromagnetic force and attract each other. The moving iron core 1323 moves toward the fixed iron core 1321 to compress the elastic member 1322 located between the two. The moving iron core 1323 is in the retracted position and disengages from the limiting hole 1110. The steering system 100 is in the unlocked state, and the steering wheel can be rotated.

[0050] like Figure 5 As shown, when the vehicle is powered off, coil 133 is de-energized, and the fixed iron core 1321 and moving iron core 1323 do not generate electromagnetic force. Under the action of elastic member 1322, moving iron core 1323 moves toward limiting hole 1110. Moving iron core 1323 is in the extended position and engages with limiting hole 1110 to fix steering column 101. Steering system 100 is in a locked state, steering wheel cannot be rotated, steering angle is limited, and system safety is ensured.

[0051] In some embodiments, the locking mechanism 130 may further include: a guide seat 134, located between the mounting sleeve 120 and the housing 131, and having a guide hole 1341 for the moving iron core 1323 to pass through. Figure 5 and Figure 7 As shown, the outer peripheral wall of the mounting sleeve 120 protrudes outward to form a mounting boss (not labeled in the figure). A first opening 121 is provided at the mounting boss. A guide seat 134 is disposed in the first opening 121. The locking mechanism 130 is fixedly installed on the mounting boss by screws and other fasteners. The moving iron core 1323 passes through the guide hole 1341.

[0052] The steering system of this utility model embodiment can achieve the switching between the locked and unlocked states of the steering wheel locking structure with a simple structure, thereby realizing the control of the steering wheel rotation.
