Description

Technical Field

[0001] This utility model application relates to the field of automotive steering wheel technology, specifically to automotive steering wheel connection structures. Background Technology

[0002] The car steering wheel is the core control device for the driver to steer the vehicle. Located in the cockpit, it is connected to the front wheels through the steering column and steering system. Its basic function is to convert the driver's rotation input into the steering angle of the wheels, thereby precisely guiding the vehicle's driving trajectory. Modern steering wheels integrate multiple functions, such as horn, multimedia control, cruise control settings, and driver assistance switches, and are often equipped with airbags. With the development of technology, the shape of the steering wheel has also evolved from the early round shape to a sporty flat-bottom design, and continues to evolve towards more precise control, more intelligent interaction, and more comprehensive safety protection.

[0003] Currently, the main method of fixing steering wheel covers to the frame relies on adhesive bonding. This method has very obvious drawbacks: First, under long-term high temperature, temperature difference changes, and frequent gripping and twisting, the adhesive is prone to aging and failure, resulting in loosening, displacement, or even separation between the cover and the frame, which seriously affects the driving experience and product quality. Second, in the event of a vehicle collision, the traditional bonding method cannot contribute to the overall crumple zone energy absorption of the steering wheel, and its connection interface may tear uncontrollably, without optimizing energy absorption. Summary of the Invention

[0004] To address the problem that the steering wheel cover and frame are primarily fixed using adhesive bonding, which is prone to aging and failure, leading to loosening, displacement, or even separation between the cover and the frame, this invention provides a steering wheel connection structure to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A car steering wheel connection structure includes a steering wheel body, an outer ring of the steering wheel body fixed to the outside of the steering wheel body, two protective sleeves on the outer side of the outer ring of the steering wheel, a number of limiting buckles fixed at the top and bottom of the outer ring of the steering wheel, a limiting groove that matches the position and number of the limiting buckles inside each protective sleeve, a fixing groove at both ends of the outer side of each protective sleeve, and a fixing ring fitted in each fixing groove.

[0006] Furthermore, an anti-slip collar is fixed to one end of the fixing collar, and a binding strap is bound to the end of the anti-slip collar away from the fixing collar. Both ends of the binding strap are provided with second fixing holes.

[0007] Furthermore, both ends of the fixing collar are fixed with connecting plates, and each of the two connecting plates has a first fixing hole. The fixing collar is fixed to the outer ring of the steering wheel by means of bolts passing through the first fixing holes and being threadedly connected to the outer ring of the steering wheel.

[0008] Furthermore, the protective sleeve is shaped as a transverse semi-circular shape, and both of the fixing grooves are located at the end of the protective sleeve furthest from the driver.

[0009] Furthermore, the limiting buckle is a "T"-shaped protrusion, and the limiting groove is an inverted "T"-shaped groove that matches the shape of the limiting buckle.

[0010] Furthermore, a fixing block is fixed to one end of the outer ring of the steering wheel near the binding band. The fixing block has a threaded hole that matches the position of the second fixing hole. The binding band is fixed to the fixing block by means of a bolt passing through the second fixing hole and being threadedly connected to the fixing block.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by having the limiting buckles on the top and bottom surfaces of the steering wheel outer ring correspond to the limiting grooves inside the two protective sleeves respectively, and by rotating the limiting buckles after they are engaged in the limiting grooves, the protective sleeve is fixed to the steering wheel outer ring by engaging. Furthermore, by setting the fixing ring inside the fixing groove opened on the outside of the protective sleeve, and then fixing the fixing ring to the steering wheel outer ring with bolts, the problem of the steering wheel protective sleeve and the frame mainly relying on adhesive bonding, which is prone to aging and failure, resulting in loosening, displacement, or even separation between the protective sleeve and the frame, is solved.

[0012] 2. In this utility model, by fixing an anti-slip ring at one end of the fixing ring, the fixing ring is set inside the fixing groove, and the anti-slip ring also wraps around the outer side of the protective sleeve, thereby improving the driver's grip on the anti-slip ring and improving the anti-slip performance. At the same time, the end of the anti-slip ring away from the fixing ring is also fixed to the fixing block by the binding strap, so that the anti-slip ring is stably fixed on the protective sleeve.

[0016] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The car steering wheel connection structure includes a steering wheel body 1, an outer ring 2 of the steering wheel body 1 fixed on the outside of the steering wheel body 1, two protective sleeves 3 on the outer side of the outer ring 2, several limiting buckles 4 fixed at the top and bottom of the outer ring 2, a limiting groove 5 that matches the position and number of the limiting buckles 4 inside each protective sleeve 3, and a fixing groove 6 at both ends of the outer side of each protective sleeve 3, with a fixing ring 7 fitted in each fixing groove 6, so that the fixing of the protective sleeve 3 and the outer ring 2 of the steering wheel is more stable.

[0018] Specifically, both ends of the fixing collar 7 are fixed with connecting plates 71, and both connecting plates 71 are provided with first fixing holes 72. The fixing collar 7 is fixed to the outer ring 2 of the steering wheel by means of bolts passing through the first fixing holes 72 and being threadedly connected to the outer ring 2 of the steering wheel. The protective sleeve 3 is shaped as a transverse semi-circular shape. Both fixing grooves 6 are set at the end of the protective sleeve 3 away from the driver. The limiting buckle 4 is a "T" shaped protrusion. The limiting groove 5 is an inverted "T" shaped groove that matches the shape of the limiting buckle 4, so that the outer ring 2 of the steering wheel and the protective sleeve 3 are engaged and fixed by the limiting buckle 4 and the limiting groove 5.

[0019] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a non-slip collar 8 is fixed to one end of the fixed collar 7, and a binding strap 9 is tied to the end of the non-slip collar 8 away from the fixed collar 7. Both ends of the binding strap 9 are provided with second fixing holes 91, so that the end of the non-slip collar 8 away from the fixed collar 7 can be fixed by the binding strap 9.

[0020] Specifically, a fixing block 10 is fixed to one end of the outer ring 2 of the steering wheel near the fixing band 9. The fixing block 10 has a threaded hole that matches the position of the second fixing hole 91. The fixing band 9 is fixed to the fixing block 10 by means of bolts passing through the second fixing hole 91 and being threadedly connected to the fixing block 10, thereby improving the fixing strength of the fixing band 9.

[0021] Working principle: After aligning the limiting grooves 5 inside the two protective sleeves 3 with the limiting buckles 4 and inserting them, the "T"-shaped protrusion of the limiting buckle 4 engages in the "T"-shaped groove of the limiting groove 5. Then, by rotating the protective sleeve 3, the limiting buckle 4 is engaged into the limiting groove 5, which increases the fixing strength. Then, the two fixing rings 7 are respectively fitted into the fixing grooves 6 on both sides of the two protective sleeves 3. Then, the fixing bolt passes through the first fixing hole 72 on the connecting plate 71 and is threadedly connected to the outer ring 2 of the steering wheel to fix it, thereby fixing the fixing rings 7 to the outer ring 2 of the steering wheel. At the same time, the protective sleeve 3 is also fixed by the limiting of the fixing rings 7.

[0022] While the fixing collar 7 is secured to the protective sleeve 3, the fixing collar 7 also drives the anti-slip collar 8 to be secured to the outside of the protective sleeve 3. At the same time, a binding strap 9 is tied to the end of the anti-slip collar 8 away from the fixing collar 7. After the second fixing hole 91 on the binding strap 9 overlaps with the fixing block 10, the binding strap 9 and the fixing block 10 are fixed together by the fixing bolt. At this time, one end of the anti-slip collar 8 is fixed to the fixing collar 7, and the other end is tied to the protective sleeve 3 by the binding strap 9, achieving stable fixation and improving the driver's operating feel.
