Description

Technical Field

[0001] The present application relates to the field of new energy vehicles, and in particular to a new energy vehicle steering wheel and a production process thereof. Background Art

[0002] A car steering wheel is a component used by the car to control the direction of travel. The simplest steering wheel is generally composed of a frame and foam. The frame, which is generally zinc alloy or aluminum alloy, includes an inner hub, an outer rim and spokes connecting the hub and the rim. The foamed part is mainly located on the rim and wraps the rim. The foaming material is generated in a foaming machine. The frame is fixed in the foaming machine during production. Some steering wheels also have leather sewn on the surface. With the development of the automobile industry, various control buttons and airbags are also integrated on the steering wheel. The most common case is the horn. The control buttons and airbags are mainly integrated in the wheel hub position. Therefore, the wheel hub part in the middle of the current car steering wheel is often larger.

[0003] The above-mentioned car steering wheel is facing the driver during use. Due to the obstruction of the car steering wheel, the car air conditioning in the driver's seat is not very effective at the beginning, and the air-conditioned wind is easily blocked. The most conventional solution is to increase air-conditioning outlets in other directions, but this requires high space utilization and adjustment inside the car. Therefore, it is possible to consider compounding the air outlet of the air conditioner onto the steering wheel for exhaust, connecting the air-conditioning outlet to the steering wheel, and exhausting air through the steering wheel rim.

[0004] The foam material of existing car steering wheels is not particularly good at venting, and its own gas emission performance is too poor, so air holes need to be processed. However, due to the molding and assembly characteristics of the foam material, processing the air holes is even more difficult, and another solution is needed to adapt the steering wheel to the function of composite air conditioning venting. Summary of the invention

[0005] On the first hand, in order to enable the steering wheel to cooperate with the car air conditioner to ventilate air, the present application provides a new energy car steering wheel.

[0006] The present application provides a new energy vehicle steering wheel that adopts the following technical solution: A new energy vehicle steering wheel comprises a frame, a wooden cover and a leather cover, wherein the frame comprises a middle mounting portion, a rim and spokes, wherein the rim is in a circular ring shape, the middle mounting portion is located at the center of the rim, the spokes are connected to the inner side of the rim and the outer side of the middle mounting portion, there are three spokes, two of the three spokes are symmetrically arranged, and the last spoke is arranged perpendicular to the other two spokes, the wooden cover is sleeved on the outer side of the rim and wraps the rim, the wooden cover is formed with a gas dispersion gap, the rim is provided with a circle of annular gas dispersion grooves, an air conditioning air pipe is installed on the spokes, one end of the air conditioning air pipe is located in the gas dispersion groove and inputs gas, the other end passes through the middle mounting portion and is connected to the air outlet part of the automobile air conditioning system, the gas dispersion groove diffuses gas through the gas dispersion gap, the leather cover is sewn to and wraps the wooden cover, and the leather cover is provided with a plurality of gas dispersion holes.

[0007] By adopting the above technical scheme, the cold air or warm air of the air-conditioning system is input into the rim of the frame through the air-conditioning air pipe, and the wooden sleeve is assembled outside the rim. On the one hand, the wooden sleeve has better air dispersion performance. On the other hand, the wooden sleeve can be assembled from multiple parts, which is more convenient for the generation of air dispersion gaps. At the same time, the wooden sleeve assembled to the frame can be produced separately, which is also convenient for processing air dispersion gaps, so as to better cooperate with the air-conditioning system to disperse air at the driving position, so that the driving position can also complete temperature adjustment more quickly after the air-conditioning is turned on. The wrapped leather cover can also better disperse other overflows in the steering wheel through the air dispersion pores. At the same time, in winter, the steering wheel can also be heated to a certain extent by the air-conditioning air, which plays a steering wheel heating function, so that the steering wheel does not need to add electric auxiliary heating for heating. It has a composite function and is safer than electric auxiliary heating. In summer, it can provide coolness when holding the steering wheel.

[0008] Optionally, the wooden sleeve includes a short tube, a lower cover and an upper cover, the short tube is a part of a circular tube, there are multiple short tubes, the multiple short tubes are sequentially mounted on the rim, and the opening of the short tube on one side facing the middle mounting portion is set as an entrance, the inner wall of the short tube is in contact with the outer wall of the rim, the cross-section of the rim is circular, the three spokes are respectively set as the first spoke, the second spoke and the third spoke, the first spoke and the second spoke are symmetrically arranged on the left and right, the diameter of the part of the rim at the first spoke and the second spoke is smaller than the opening width of the entrance, the diameter of the part of the rim for the short tube to be mounted is larger than the opening width of the entrance, and the short The surface of the tube on the side of the inlet is a plane, and the multiple short tubes wrap the rim except the part close to the first spoke and the second spoke. The lower cover and the upper cover are assembled to form a tubular ring with a hollow interior, and the lower cover and the upper cover are respectively provided with the short tubes above and below and cooperate to wrap all the short tubes. The outer side of the lower cover only reaches the middle thickness position of the rim, and the inner side of the lower cover protrudes from the middle thickness position of the rim and fills the part of the short tube where the inlet is opened. The inner side of the upper cover is a vertical surface, and the inner side of the upper cover cooperates with the protruding part of the lower cover to form the air dispersion gap, and the leather cover wraps the upper cover and the lower cover and fixes the upper cover and the lower cover.

[0009] By adopting the above technical scheme, the wooden sleeve is assembled from multiple short tubes, a lower cover and an upper cover, wherein the setting of the short tubes simultaneously meets the requirements of the setting of the air dispersion gap and the assembly firmness. Compared with the method of directly punching holes on the short tubes to form the air dispersion gaps, the structural strength of the short tubes is better maintained and the processing difficulty is reduced. After the short tubes enter through the smaller diameter position on the rim, they can be initially fixed by rotating to other positions of the rim. The assembly of the upper cover and the lower cover not only stabilizes the short tubes, but also makes the wooden sleeve a circular tubular structure to meet the requirements of the steering wheel structure. The upper cover and the lower cover are more convenient to assemble and install, and the gap generated is just used for the air dispersion process.

[0010] Optionally, the short tube is located at the position of the third spoke and cooperates with the third spoke to limit the rotation of the corresponding short tube. The short tube between the first spoke and the third spoke and the short tube between the second spoke and the third spoke are both embedded end to end to achieve a stable relative position between adjacent short tubes. The upper cover protrudes toward the lower cover and is provided with a filling ridge, which fills the gap between the lower cover and the rim at the outer side of the first spoke and the second spoke position corresponding to the first spoke and the second spoke.

[0011] By adopting the above technical scheme, the automatic rotation of some short tubes is limited by the third spoke, so that the short tubes on the left and right of the third spoke are better restricted in rotational movement. Since the short tubes, as parts outside the skeleton, need to have a certain elastic deformation ability, the steering wheel makes a completely rigid collision from time to time when in contact with a person. Therefore, the short tubes have a certain rotational deformation possibility on the rim, especially the shorter the length of the short tube, the greater the possibility of deformable rotation. The short tubes are further limited by the third spoke, and the relative state of adjacent short tubes is further kept stable by the head-to-tail embedding between adjacent short tubes. The upper cover is provided with the filling convex strips, on the one hand, to achieve the pre-positioning installation of the upper cover, especially the precise positioning of the upper cover in the left and right directions.

[0012] Optionally, a ventilation groove is provided inside the end surface of only the portion of the short tube located between the first spoke and the second spoke, and an annular convexity is formed on the outer side of the short tube, and embedding grooves and embedding blocks are respectively provided on the two end surfaces of the remaining short tubes, and the embedding blocks are embedded in the embedding grooves to achieve embedding fit between adjacent short tubes, the lower cover is pre-clamped and fixed to the annular convexity, and the upper cover is pre-clamped and fixed to the embedding blocks and the embedding grooves.

[0013] By adopting the above technical scheme, the opening of the ventilation groove, on the one hand, facilitates the smooth flow of gas inside the wooden casing, so that the gas can be better discharged from the air dispersion gap; on the other hand, the opening of the ventilation groove also realizes the pre-clamping and fixing of the lower cover, and the setting of the embedded block can be further used for the pre-clamping and fixing of the upper cover. The various structures are coordinated layer by layer to realize a variety of wood degrees.

[0014] Optionally, both end surfaces of the lower portion of the short tube are provided with embedding holes, and gravity pieces are embedded in the embedding holes. Driven by the gravity pieces, the short tube maintains a state in which the entrance is directed toward the middle mounting portion.

[0015] By adopting the above technical solution and setting the gravity piece, on the one hand, the short tube can better maintain the state of opening toward the middle mounting portion under the action of the gravity piece, solve the gravity imbalance state of the short tube caused by opening the entry port, reduce the relative deformation stress between the short tube and the wheel rim, and make the state of the short tube more stable. On the other hand, the gravity piece can also be used as a fastener for the lower cover mounting position, making the lower cover mounting more firmly.

[0016] In the second aspect, in order to produce the above-mentioned steering wheel, the present application provides a production process of a new energy vehicle steering wheel, which adopts the following technical solution: A production process for a new energy vehicle steering wheel comprises the following steps: S1, casting the frame, making the various parts of the wooden case and the leather case; S2. Put the short tube onto the corresponding position of the wheel rim of the frame; When assembling the short tubes, the skeleton is fixed, and the short tubes are installed alternately by four manipulators. The four manipulators are arranged at four corners, and the four manipulators are grouped in pairs. The skeleton is fixed on a rotatable platform, and the rotation of the skeleton is controlled. The two manipulators of one pair of manipulators respectively install the short tubes between the first spoke and the third spoke and the short tubes between the first spoke and the second spoke, and the two manipulators of the other pair of manipulators respectively install the short tubes between the second spoke and the third spoke and the short tubes between the second spoke and the first spoke. The manipulators clamp the short tubes into the position where the diameter of the wheel rim is smaller than the size of the entrance, and then complete the installation of the short tubes by rotating the skeleton.

[0017] S3, complete the installation of the lower cover and the upper cover in sequence; S4, after the frame and the wooden sleeve are installed, they are placed in a foaming machine for foaming; The first spoke, the second spoke and the third spoke are foamed, wherein the first spoke and the second spoke are provided with pipe grooves connected to the air diffusion groove, the air conditioning air pipe is installed in the pipe grooves and covered with foam for fixation, and foaming is also performed at the position where the wheel rim diameter is smaller than the size of the inlet port to fill the gap between the lower cover and the upper cover to further strengthen the clamping and fixing state of the lower cover and the upper cover.

[0018] S5. Sew the leather cover onto the wooden cover.

[0019] By adopting the above technical scheme, the four manipulators are assembled alternately in groups of two, which is more efficient. The short pipes are installed by rotating the skeleton rather than the manipulators, which is more green and energy-saving. The air conditioning air duct is fixed through the foaming process, making the air conditioning air duct installation more firmly. At the same time, there is no need for a separate reinforcement process. The foaming fills the space reserved between the upper cover and the lower cover, further fastening the various components of the skeleton and the wooden sleeve together to form a whole.

[0020] Optionally, in step S2, the manipulator for installing the short tube between the first spoke and the third spoke and the manipulator for installing the short tube between the second spoke and the third spoke among the four manipulators have the function of rotating around the skeleton, and when installing the short tube between the first spoke and the third spoke, the manipulator rotates the short tube until it abuts against the previous short tube, and when installing the short tube between the second spoke and the third spoke, the manipulator also rotates the short tube until it abuts against the previous short tube.

[0021] By adopting the above technical solution, when installing the short tubes that cooperate with the third spoke, the corresponding manipulator installs the short tubes to the corresponding positions by rotating relative to the skeleton, wherein the first one is installed to cooperate with the third spoke, and the subsequent short tubes are installed to be embedded with the previous short tubes, so that the cooperation state between the short tubes is completed during installation, avoiding deformation of the short tubes and the inability to achieve the cooperation state.

[0022] Optionally, in step S4, the air conditioning air pipe is connected to an air pump, and during the air intake and foaming process, air is supplied to the air conditioning air pipe at a certain rate through the air pump.

[0023] By adopting the above technical solution, the air pipe of the air conditioner is not easily blocked during foaming.

[0024] Optionally, a touch controller is provided under two areas of the wheel rim corresponding to a group of initial positions of the manipulator, and the touch controller is flipped. When the manipulator moves toward the direction of the skeleton, it pushes the touch controller to flip inward. When all the short tubes are installed, the two sections of the short tubes are clamped and fixed by the two touch controllers, and the end surfaces of the two touch controllers facing the third spoke are provided with stop buttons. When the short tubes abut the stop buttons, the manipulator no longer rotates. After the short tube set is installed on the skeleton, the upper cover is first clamped, the lower cover is placed in the foaming machine, and the skeleton with the short tubes and the upper cover installed is placed in the foaming machine while the lower cover and the skeleton are assembled.

[0025] By adopting the above technical solution, after the short tubes are installed, if the subsequent robot moves to the original position again, it will push the other short tubes. However, it is too complicated to make the program move to the corresponding position each time, and the requirements for operation are too high. There cannot be any mistakes, and the fault tolerance rate is low. In this solution, through the existence of the touch controller, the short tube at the third spoke position is kept in the restriction of the third spoke state through repeated movement, and the robot still moves to the same position. When the last short tube is installed, the previous short tube rotates around the rim to abut the touch controller, so that the robot stops rotating relative to the skeleton, solving the above problem. The touch controller also stabilizes the relative position of the short tubes, facilitates the assembly of the upper cover, and makes the upper cover better pre-installed, while the lower cover is assembled in the foaming machine, and the whole assembly process is more reasonable and orderly.

[0026] Optionally, the leather case is first cut into a circular ring shape, and when the leather case is cut, the middle part of the leather case circular ring is first clamped, and then the edge of the leather case is cut and formed, and at the same time, when the leather case is cut, the edge of the leather case is pierced to complete at least two circles of sewing holes, wherein the sewing holes on the outer side are used for sewing and forming.

[0027] By adopting the above technical scheme, the sewing holes are opened at the same time during cutting, and the sewing holes are opened first and then the leather cover is sewn, which makes the sewing process of the leather cover more labor-saving. At the same time, the sewing holes at the sewing position after the leather cover is sewn can also be used for better air dissipation, and the opening of two rows of sewing holes allows the inner sewing holes to be used for air dissipation.

[0028] To sum up, the cold air or warm air of the air-conditioning system is input into the rim of the frame through the air-conditioning air pipe, and the wooden cover is used for assembly outside the rim. On the one hand, the wooden cover has better air dispersion performance. On the other hand, the wooden cover can be assembled from multiple parts, which is more convenient for the generation of air dispersion gaps. At the same time, the wooden cover assembled to the frame can be produced separately, which is also convenient for processing air dispersion gaps, so as to better cooperate with the air-conditioning system to disperse air at the driving position, so that the driving position can also complete temperature adjustment more quickly after the air-conditioning is turned on. The wrapped leather cover can also better disperse other air in the steering wheel through the air dispersion pores. At the same time, in winter, the steering wheel can also be heated to a certain extent by the air-conditioning air, which plays a steering wheel heating function, so that the steering wheel does not need to add electric auxiliary heating for heating. It has composite functions and is safer than electric auxiliary heating. In summer, it can provide coolness when holding the steering wheel. BRIEF DESCRIPTION OF THE DRAWINGS

The two manipulators 8 of one pair of manipulators 8 respectively install the short tube 21 between the first spoke 131 and the third spoke 133 and the short tube 21 between the first spoke 131 and the second spoke 132, and the two manipulators 8 of the other pair of manipulators 8 respectively install the second spoke 13 2 and the short tube 21 between the third spoke and the short tube 21 between the second spoke 132 and the first spoke 131, that is, the manipulator 8 located on the same side installs the first section short tube 211 or the second section short tube 212, the manipulator 8 clamps the short tube 21 into the position of the rim 12 for the short tube 21 to enter, and then completes the installation of the short tube 21 by rotating the skeleton 1. The rotation angle of the skeleton 1 is the angle of the first spoke 131 rotating from an adjacent manipulator 8 to the nearest adjacent manipulator 8, and when the first spoke 131 and the second spoke 132 are located between the two manipulators 8, the four manipulators 8 just correspond to the four short tubes 21 on the rim 12 that are closest to the first spoke 131 and the second spoke 132.

[0043] At the same time, the manipulator 8 among the four manipulators 8 that installs the short tube 211 of the first section has the function of rotating around the skeleton 1. When installing the short tube 211 of the first section, the manipulator 8 rotates the short tube 21 to abut against the previous short tube 21. Specifically, the manipulator 8 drives the short tube 21 to rotate just to partially enter the position of the third spoke 133. By continuously installing the short tubes 21 to the corresponding positions, it is ensured that the first short tube 21 must cooperate with the third spoke 133, and it is also ensured that the subsequent short tubes 21 must be installed in abutment with the previous short tubes 21. At the same time, the angle that the manipulator 8 needs to move around the skeleton 1 is reduced as much as possible, the rotation time is reduced, and the efficiency of alternating installation is improved.

[0044] In summary: among the four manipulators 8, the manipulator 8 used for installing the short tube 211 of the first section has three degrees of freedom: turnover, rotation and horizontal displacement. The rotation is used for loading and unloading, the horizontal displacement is used for placing the short tube 21 on the rim 12, and the turnover is used to drive the short tube 21 to move on the rim 12. The manipulator 8 for installing the short tube 212 of the second section has only two degrees of freedom: rotation and horizontal displacement.

[0045] As can be seen from the above, when the short tube 21 of the first section is installed, the short tube 21 before is repeatedly pushed. A touch controller 9 is arranged below two areas of the rim 12 corresponding to the initial position of a group of manipulators 8. The touch controller 9 is flipped. When the manipulator 8 moves toward the skeleton 1, it pushes the touch controller 9 to flip inward. When all the short tubes 21 are installed, the two sections of the short tube 21 are clamped and fixed by the two touch controllers 9, that is, the touch controller 9 can flip into the area of ​​the rim 12 corresponding to the first spoke 131 and the second spoke 132, and the two touch controllers 9 face the first spoke 131 and the second spoke 132. A stop button is provided on the end face of the segment short tube 211. When the short tube 21 abuts against the stop button, the manipulator 8 no longer rotates. The touch controller 9 also plays a positioning restriction role when entering the space of the smaller diameter part of the rim 12. That is, when a group of manipulators 8 that do not correspond to the touch controller 9 are assembling the short tube 21, the touch controller 9 can limit the rotation of the skeleton 1 to the corresponding angle and the skeleton 1 cannot rotate any further. At the same time, when the manipulator 8 corresponding to the touch controller 9 is assembling the short tube 21, the program design requires the assembly of the second to last set of short tubes 21 to achieve the above functions.

[0046] S3, completing the installation of the lower cover 22 and the upper cover 23 in sequence; After the short tube 21 is installed on the skeleton 1, the upper cover 23 is first clamped, and the lower cover 22 is placed in the foaming machine. The skeleton 1 with the short tube 21 and the upper cover 23 installed is placed in the foaming machine and the assembly of the lower cover 22 and the skeleton 1 is completed. The touch controller 9 is provided with an air pressure protrusion structure. When the upper cover 23 is installed, the air column protrudes through the foot switch to better clamp the first section short tube 211 and the second section short tube 212. The air column corresponding to the first section short tube 211 is compounded with the stop switch, that is, the stop switch is columnar, and the first section short tube 211 is clamped and fixed by controlling the stop switch to protrude.

[0047] S4, after the frame 1 and the wooden casing 2 are installed, they are placed in a foaming machine for foaming; The first spoke 131, the second spoke 132 and the third spoke 133 are foamed, and at the same time, the corresponding position of the rim 12 is also foamed to fill the gap between the lower cover 22 and the upper cover 23 to further strengthen the clamping and fixing state of the lower cover 22 and the upper cover 23. Before foaming, the air conditioning air pipe 6 is connected to the air pump, and during the air intake foaming process, air is supplied to the air conditioning air pipe 6 at a certain rate through the air pump.

[0048] S5, sew the leather cover 3 outside the wooden cover 2.

[0049] Among them, the leather case 3 is first cut, and the leather case 3 is cut into a circular ring. When the leather case 3 is cut, the middle part of the circular ring of the leather case 3 is first clamped, and then the edge of the leather case 3 is cut and formed. At the same time, when the leather case 3 is cut, the edge of the leather case 3 is pierced to complete at least two circles of sewing holes 32, and the outer sewing holes 32 are used for sewing and forming.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
