Vehicle CD column assembly and vehicle

Abstract

The invention relates to a rotary connector circuit protection system, a steering wheel assembly and a vehicle. The rotary connector circuit protection system comprises a power source, a rotary connector and a control module. One end of the power supply is electrically connected to one end of the control module, the other end of the power supply is grounded, and the other end of the control module is electrically connected to the rotary connector; and when the vehicle is in a power-on state, the control module is used for detecting the current of the rotary connector and disconnecting the current of the rotary connector under the condition that the current of the rotary connector is greater than or equal to a preset value. Therefore, if the control module detects that the current of the rotary connector is greater than or equal to the preset value, the overcurrent of the rotary connector is relatively large, the flat cable is easy to overheat and ablate, the control module cuts off the current of the rotary connector, and no current passes through the flat cable, so that the ablation caused by overheat is avoided, and the service life is prolonged; the risk that the rotary connector is prone to burning a vehicle or even exploding is reduced, and the safety of the vehicle is improved.

The present application can also be implemented or applied in other different specific embodiments, and various modifications or changes can be made to the details of the present application based on different views and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, but not for limiting the protection scope of the present application.

[0035] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the structures related to the present application are shown in the drawings, but not drawn according to the number, shape and size of the structures in actual implementation. The type, number and proportion of each structure in actual implementation can be arbitrarily changed, and the structure layout type can also be more complex.

[0036] The present embodiment provides a vehicle CD pillar assembly, which is part of a vehicle body, as shown in Figures 1-7 , wherein Figure 3 The arrow in the figure represents the stress transmission direction, and the vehicle CD pillar assembly comprises a C pillar structure 10, a D pillar structure 20 and a wheel bulge structure 30.

[0037] The D pillar structure 20 is connected to the C pillar structure 10 along the first direction X.

[0038] In the case that the vehicle CD column assembly is subjected to a first stress transmitted along the first direction X, the C column structure 10 transmits the first stress to the D column structure 20 along the first direction X;

[0039] The drum bump structure 30 is connected to the bottom of the C column structure 10 along the third direction Z;

[0040] In the case that the vehicle CD column assembly is subjected to a second stress transmitted along the third direction Z, the second stress is transmitted to the C column structure 10 on the drum bump structure 30 along the third direction Z, and the C column structure 10 decomposes the second stress into a first partial stress transmitted along the first direction X and a second partial stress transmitted along the second direction Y;

[0041] The first direction X is perpendicular to the second direction Y and the third direction Z respectively.

[0042] In the embodiments of the present application, the vehicle CD column assembly is composed of the C column structure 10, the D column structure 20 and the drum bump structure 30, which greatly reduces the number of parts, is beneficial to the lightweight design of the vehicle, and makes the connection process between the structures relatively simple, which is beneficial to improve the production efficiency and can also avoid the existence of a region with a large stress concentration. When the vehicle CD column assembly is subjected to a first stress transmitted along the first direction X, the C column structure 10 can transmit the first stress to the D column structure 20 along the first direction X because the D column structure 20 is connected to the C column structure 10 along the first direction X, and then the rear apron of the vehicle can be transmitted to realize the force transmission closed loop of the first stress along the first direction X.

The first partial stress can be transmitted to the D column structure 20 along the first direction X, and then the rear apron of the vehicle can be transmitted to realize the force transmission closed loop of the first partial stress along the first direction X. The second partial stress is transmitted along the second direction Y through the C column structure 10, and then the roof cross beam of the vehicle can be transmitted to realize the force transmission closed loop of the second partial stress along the second direction Y. Thus, the vehicle CD column assembly has a good force transmission effect on the whole vehicle, and the vehicle has high stiffness and strength. Compared with the prior art, the number of parts of the vehicle CD column assembly in the embodiments of the present application can be reduced to less than half of the traditional CD column structure 20. Specifically, the C column structure 10, the D column structure 20 and the drum bump structure 30 can be connected relatively stably and reliably by welding, which reduces the welding level and makes the welding process simple, facilitating the layout of the production line and effectively improving the production efficiency.

[0044] For example, in the embodiments of the present application, the vehicle will generate stress transmission due to vibration during driving, and the stress transmitted to the vehicle CD column assembly can generally include stress transmitted along a first direction X and stress transmitted along a second direction Y, wherein the first stress transmitted along the first direction X can be derived from the upper side beam of the vehicle, and the second stress transmitted along a third direction Z can be derived from the stress transmitted upward from the rocker and chassis shock absorber at the bottom of the vehicle to the wheel cover. For example, the first direction X can be the length direction of the vehicle body, the second direction Y can be the width direction of the vehicle body, and the third direction Z can be the height direction of the vehicle body, and the first direction X and the second direction Y and the third direction Z are perpendicular to each other in pairs.

[0046] In the embodiment of the present application, when the vehicle CD column assembly is subjected to a first stress transmitted along the first direction X, since the first connecting plate assembly extends along the first direction X and the D column structure 20 is connected to the first connecting plate assembly along the first direction X, that is, the first connecting plate assembly and the D column structure 20 both extend along the first direction X, therefore the first connecting plate assembly can transmit the first stress to the D column structure 20 along the first direction X, and then transmit the rear apron of the vehicle, so as to realize the force transmission closed loop of the first stress along the first direction X. When the vehicle CD column assembly is subjected to a second stress transmitted along the third direction Z, the second stress can be transmitted to the C column structure 10 along the third direction Z on the drum package structure 30, and the first connecting plate assembly and the second connecting plate assembly of the C column structure 10 can decompose the second stress into a first partial stress and a second partial stress, wherein the first partial stress is transmitted to the D column structure 20 along the first direction X through the first connecting plate assembly, and then can transmit the rear apron of the vehicle, so as to realize the force transmission closed loop of the first partial stress along the first direction X; the second partial stress is transmitted along the second direction Y through the second connecting plate assembly, and then can transmit the roof cross beam of the vehicle, so as to realize the force transmission closed loop of the second partial stress along the second direction Y. Therefore, the vehicle CD column assembly has a good force transmission effect on the whole vehicle, so that the vehicle has a high stiffness and strength.

[0047] Optionally, in the embodiment of the present application, the first connecting plate assembly includes a first connecting plate 111 and a second connecting plate 121, the first connecting plate 111 and the second connecting plate 121 extend along the first direction X, the second connecting plate assembly includes a third connecting plate 112 and a fourth connecting plate 122, the third connecting plate 112 and the fourth connecting plate 122 extend along the second direction Y; the C column structure 10 includes a C column outer plate 11 and a C column inner plate 12, the C column inner plate 12 is connected to the C column outer plate 11 along the second direction Y, the first connecting plate 111 and the third connecting plate 112 are arranged on the C column outer plate 11, the second connecting plate 121 and the fourth connecting plate 122 are arranged on the C column inner plate 12, and the D column structure 20 is connected to the C column inner plate 12 along the first direction X.

[0048] That is, the C-pillar outer plate 11 and the C-pillar inner plate 12 form the C-pillar structure 10, the first connecting plate 111 extending along the first direction X is arranged on the C-pillar outer plate 11, the second connecting plate 121 extending along the first direction X is arranged on the C-pillar inner plate 12, and the first connecting plate 111 and the second connecting plate 121 form a first connecting plate assembly extending along the first direction X to transmit a first stress along the first direction X to which the vehicle CD pillar assembly is subjected. In addition, the third connecting plate 112 extending along the second direction Y is arranged on the C-pillar outer plate 11, the fourth connecting plate 122 extending along the second direction Y is arranged on the C-pillar inner plate 12, and the second connecting plate 121 and the fourth connecting plate 122 form a second connecting plate assembly extending along the second direction Y. In this way, when a second stress along the third direction Z is transmitted to the vehicle CD pillar assembly, the second stress can be decomposed into a stress along the second direction Y by the third connecting plate 112 and the fourth connecting plate 122.

[0049] In some optional embodiments of the present application, the C-pillar outer plate 11 and the C-pillar inner plate 12 can be arranged in a bent structure to form a cavity by connecting the C-pillar outer plate 11 and the C-pillar inner plate 12, so as to improve the transmission effect of the stress, so that the vehicle CD pillar assembly has better force transmission reliability and stability. Specifically, the first connecting plate 111 and the second connecting plate 121 form a cavity extending along the first direction X, so that the first connecting assembly has a better force transmission effect on the stress transmitted along the first direction X. The third connecting plate 112 and the fourth connecting plate 122 form a cavity extending along the second direction Y, so that the second connecting assembly has a better force transmission effect on the stress transmitted along the second direction Y.

[0050] For example, in the embodiments of the present application, the first connecting plate 111 and the third connecting plate 112 can be an integral molding structure, so that the first connecting plate 111 and the third connecting plate 112 have better connection strength and reduce material loss and manufacturing processes. Similarly, the second connecting plate 121 and the fourth connecting plate 122 can be an integral molding structure, so that the second connecting plate 121 and the fourth connecting plate 122 have better connection strength.

[0051] Optionally, in the embodiments of the present application, the C-pillar structure 10 further includes a back door mounting plate 13, the second connecting plate 121 and the fourth connecting plate 122 are arranged in a spaced manner to form an opening, and the back door mounting plate 13 is connected to the opening to close the opening. In this way, the opening between the second connecting plate 121 and the fourth connecting plate 122 is closed by the back door mounting plate 13, so as to close one end of the C-pillar outer plate 11 and the C-pillar inner plate 12.

[0052] Compared with the prior art, the C-pillar outer plate 11 is cut from the area outside the back door mounting surface, and the opening is closed by the back door mounting plate 13. In this way, the structure of the C-pillar outer plate 11 is relatively simple, the stamping difficulty is reduced, the manufacturing process is reduced, and the C-pillar outer plate 11 has good bending and torsional stiffness. Specifically, in the embodiment of the application, the back door mounting plate 13 can be a back door hinge mounting plate, and the back door hinge mounting plate can be provided in a box structure to enhance the stiffness of the back door mounting plate 13 to the back door connecting structure.

The back door reinforcing piece 131 is used to connect the back door stay rod. In this way, the back door stay rod has a relatively stable and reliable connection effect through the back door reinforcing piece 131. For example, the back door reinforcing piece 131 can be a reinforcing plate, and the reinforcing plate can be welded to the protruding reinforcing piece mounting portion 113 of the C-pillar outer plate 11. In addition, the reinforcing plate can also be connected to the reinforcing piece mounting portion 113 by a fastener, such as a bolt or a screw, and the specific connection mode of the back door reinforcing piece 131 is not limited in the embodiment of the application.

Specifically, the vehicle CD-pillar assembly is arranged near the tail end of the vehicle, and therefore the retractor reinforcing piece 22 is used to connect the rear row, i.e., the second row, safety belt retractor.

[0055] For example, in the embodiment of the present application, the C-pillar inner panel 12 is provided with a circular arc structure adapted to the shape of the vehicle, and the C-pillar inner panel 12 is divided into the C-pillar inner panel 12 and the D-pillar structure 20 at a position of a rear straight line segment of the circular arc structure of the C-pillar inner panel 12 passing the door stop, that is, the position of the circular arc structure of the C-pillar inner panel 12 passing the door stop is set as the position of the division, and the C-pillar inner panel 12 is divided into the C-pillar inner panel 12 and the D-pillar structure 20. Since the lower the position of the division, the lower the utilization rate of the connecting plate, it is obtained through experiments that the position of the circular arc structure of the C-pillar inner panel 12 passing the door stop is set as the position of the division, and the utilization rate of the material of the C-pillar inner panel 12 is maximized. In addition, according to different vehicle models, the position of the division can also be set as a position of a rear straight line segment of the circular arc structure of the C-pillar inner panel 12 passing the door stop, which is 16 mm, 17 mm, 19 mm or 20 mm, and the like, and can be set according to actual needs.

Moreover, the cavity is formed at the through hole 311, and the vibration isolation glue is clamped in the through hole 311, so that the vehicle has better air tightness and NVH (Noise, Vibration, Harshness) performance, improves the driving comfort, and also enhances the power transmission performance of the vehicle and improves the rigidity of the vehicle body. Specifically, the side inner reinforcing plate 32 can extend to the wheel cover bottom of the vehicle, and the wheel drum outer plate 31 and the side inner reinforcing plate 32 together form the cavity.
