[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0041] Reference below Figure 1-Figure 3 The rotating shaft 400 assembly, the central control display screen and the vehicle according to the embodiments of the present application are described.
[0042] The present application embodiment provides a rotating shaft 400 assembly, which is applied to a central control display screen of a vehicle, such as Figure 1-Figure 3 As shown, the rotating shaft 400 assembly includes a bearing base 100 , a bearing cover 300 , a rotating shaft 400 and an elastic member 200 .
[0043] The bearing base 100 may be a trapezoidal structure, a truncated cone structure or other shaped structures, for example Figure 1-Figure 3 As shown, the bearing base 100 is a rectangular structure.
[0044] like Figure 1-Figure 3 As shown, the bearing cover 300 is installed on the bearing base 100, and a mounting position 110 is defined between the bearing cover 300 and the bearing base 100. The upper surface of the bearing base 100 is provided with an arc-shaped groove that is recessed downward relative to the upper surface of the bearing base 100. The bearing cover 300 defines an arc-shaped groove that bends upward. When the bearing cover 300 is installed on the bearing base 100, the arc-shaped groove of the bearing cover 300 cooperates with the arc-shaped groove of the bearing base 100 to form a circular mounting position 110.
[0045] like Figure 1-Figure 3 As shown, the rotating shaft 400 is rotatably installed on the mounting position 110 around its own axis, and the diameter of the circular mounting position 110 formed by the bearing cover 300 and the bearing base 100 can be larger than the diameter of the rotating shaft 400 to reduce the friction between the rotating shaft 400 and the bearing cover 300 and the bearing base 100 during rotation.
[0046] like Figure 1-Figure 3 As shown, the elastic member 200 is installed on the bearing cover 300, and the elastic member 200 elastically stops against the outer circumference of the rotating shaft 400, that is, the elastic member 200 and the rotating shaft 400 are interference fit so that the elastic member 200 applies a certain pressure to the rotating shaft 400. The elastic member 200 can elastically stop against the outer circumference of the upper end of the rotating shaft 400, and can also elastically stop against the outer circumference of the lower end of the rotating shaft 400.
[0047] In the actual implementation process, Figure 1-Figure 3As shown, when installing the rotating shaft 400 assembly, first install the bearing cover 300 on the bearing base 100, and install the elastic member 200 on the bearing cover 300, and then install the rotating shaft 400 axially on the mounting position 110 between the bearing cover 300 and the bearing base 100. When installing the rotating shaft 400, the rotating shaft 400 squeezes the elastic member 200 outward. At this time, the elastic member 200 gives a reaction force to the rotating shaft 400. When the rotating shaft 400 rotates, the elastic member 200 continues to give a certain pressure to the rotating shaft 400, that is, the friction between the elastic member 200 and the rotating shaft 400 increases, and the resistance to the rotation of the rotating shaft 400 increases. At this time, the rotating shaft 400 rotates at a lower rotation speed.
[0048] According to the rotating shaft 400 assembly provided in the embodiment of the present application, the friction between the elastic member 200 and the rotating shaft 400 can be increased by utilizing the peripheral elastic stop between the elastic member 200 and the rotating shaft 400, thereby reducing the speed of the rotating shaft 400 during rotation, reducing the unexpected rotation of the rotating shaft 400 under the action of vibration and impact, and improving the safety of the user. In addition, the cost of the elastic member 200 is relatively low, which can help reduce the production cost of the vehicle.
[0049] In some embodiments, Figure 1 and Figure 3 As shown, the elastic member 200 includes a connected mounting section 210, a cantilever section 220 and a contact section 230. The mounting section 210 is mounted on the bearing cover 300. The end face of the contact section 230 facing the rotating shaft 400 contacts the outer peripheral surface of the rotating shaft 400 and elastically stops. The cantilever section 220 is connected between the mounting section 210 and the contact section 230.
[0050] The mounting section 210 may be mounted on the upper surface of the bearing cover 300 or on the side of the bearing cover 300, for example. Figure 1 and Figure 3 As shown, the mounting section 210 is mounted on the upper surface of the bearing cover 300 .
[0051] The contact section 230 may contact the outer circumference of the upper end of the rotating shaft 400, or may contact the outer circumference of the lower end or other positions of the rotating shaft 400, for example. Figure 1 and Figure 3 As shown, the contact section 230 contacts the outer circumference of the upper end of the rotating shaft 400 , and the cantilever section 220 is connected between the contact section 230 and the mounting section 210 .
[0052] like Figure 1 and Figure 3 As shown, the end surface of the contact segment 230 facing the rotating shaft 400 contacts and elastically stops against the outer peripheral surface of the rotating shaft 400 , that is, the contact segment 230 elastically stops against the rotating shaft 400 in the form of surface contact.
[0053] By setting the end face of the contact section 230 facing the rotating shaft 400 to contact and elastically stop the outer peripheral surface of the rotating shaft 400, the contact area between the elastic member 200 and the rotating shaft 400 can be increased, the wear of the elastic member 200 on the outer peripheral surface of the rotating shaft 400 can be reduced, and the service life of the rotating shaft 400 can be extended.
[0054] In some embodiments, Figure 1 and Figure 3 As shown, the contact segment 230 is an arc-shaped structure, and the curvature of the contact segment 230 is equal to the curvature of the rotating shaft 400 .
[0055] The contact segment 230 may be a superior arc structure or an inferior arc structure, for example Figure 1 and Figure 3 As shown, the contact segment 230 is a minor arc structure.
[0056] like Figure 1 and Figure 3 As shown, the curvature of the contact segment 230 is equal to the curvature of the shaft 400, that is, the bending degree of the contact segment 230 is the same as the bending degree of the shaft 400. When the end surface of the contact segment 230 facing the shaft 400 contacts the shaft 400, the end surface of the contact segment 230 facing the shaft 400 can fit integrally with the shaft 400.
[0057] By setting the contact section 230 to an arc-shaped structure and making the curvature of the contact section 230 equal to the curvature of the rotating shaft 400, the contact area between the contact section 230 and the rotating shaft 400 can be further increased, the elastic stopping force of the elastic member 200 on the rotating shaft 400 can be improved, and the wear of the elastic member 200 on the rotating shaft 400 can be reduced.
[0058] In some embodiments, Figure 1 and Figure 3 As shown, the axial width of the contact segment 230 along the rotation axis 400 is greater than the axial width of the cantilever segment 220 along the rotation axis 400 .
[0059] Among them, Figure 1 and Figure 3 As shown, the contact section 230 , the cantilever section 220 and the mounting section 210 can all be sheet-like structures with relatively small thickness, and the contact section 230 , the cantilever section 220 and the mounting section 210 all have a certain width along the axial direction of the rotating shaft 400 .
[0060] By setting the axial width of the contact section 230 along the rotating shaft 400 to be greater than the axial width of the cantilever section 220 along the rotating shaft 400, the contact area between the contact section 230 and the rotating shaft 400 can be further increased, the elastic stopping force of the elastic member 200 on the rotating shaft 400 can be improved, and the wear of the elastic member 200 on the rotating shaft 400 can be reduced. At the same time, the material usage of the cantilever section 220 can be reduced, thereby reducing production costs.
[0061] In some embodiments, Figure 3 As shown, the cantilever section 220 includes a first section 221 and a second section 222 connected in sequence, the first section 221 is connected to the mounting section 210, and the second section 222 is connected to the contact section 230, the first section 221 is bent relative to the mounting section 210 in a direction away from the bearing base 100, the first section 221 and the second section 222 are bent, and the axial distance from the end of the second section 222 close to the first section 221 to the rotating shaft 400 is greater than the axial distance from the end of the second section 222 away from the first section 221 to the rotating shaft 400.
[0062] The first section 221 is connected to the mounting section 210, and the first section 221 is bent relative to the mounting section 210 in a direction away from the rotation axis 400. The first section 221 and the mounting section 210 may be bent at an angle or at a rounded angle. Figure 3 As shown, the first section 221 and the mounting section 210 are rounded bends, that is, the connection between the first section 221 and the mounting section 210 is rounded to improve the elastic deformation capacity between the first section 221 and the mounting section 210 and reduce the probability of fracture between the first section 221 and the mounting section 210.
[0063] The second section 222 is bent relative to the first section 221 toward the rotation axis 400. The second section 222 and the first section 221 may be bent at an angle or at a rounded angle. Figure 3 As shown, there is a rounded bend between the second section 222 and the first section 221, that is, the connection between the second section 222 and the first section 221 is rounded to improve the elastic deformation capacity between the second section 222 and the first section 221 and reduce the probability of fracture between the second section 222 and the first section 221.
[0064] like Figure 3 As shown, the axial distance from the end of the second section 222 close to the first section 221 to the rotating shaft 400 is greater than the axial distance from the end of the second section 222 away from the first section 221 to the rotating shaft 400, that is, the end of the second section 222 away from the first section 221 is inclined toward the rotating shaft 400.
[0065] like Figure 3 As shown, since the end of the second section 222 away from the first section 221 is inclined toward the rotating shaft 400, and the end of the second section 222 away from the first section 221 is connected to the contact section 230, when the elastic member 200 and the rotating shaft 400 are elastically stopped, the second section 222 applies a downwardly inclined force to the contact section 230, so that the contact section 230 can fit the rotating shaft 400 and apply a downward force to the rotating shaft 400, thereby increasing the friction between the rotating shaft 400 and the elastic member 200 and reducing the rotation speed of the rotating shaft 400.
[0066] It should be noted that the length, width and other dimensions of the first section 221 and the second section 222 can be determined by combining finite element analysis and physical sample testing.
[0067] By configuring the first section 221 and the second section 222 , the second section 222 can provide an inclined downward force to the contact section 230 to improve the stability of the fit between the contact section 230 and the shaft 400 , thereby improving the stability of the force exerted by the elastic member 200 on the shaft 400 .
[0068] In some embodiments, Figure 1 As shown, the mounting section 210 has a first connection structure 211 for connecting to the bearing cover 300, the bearing cover 300 has a second connection structure for connecting to the bearing base 100, and the rotating shaft 400 assembly also includes a connecting member, which is connected to both the first connection structure 211 and the second connection structure.
[0069] The first connection structure 211 may be a first mounting hole, and the first mounting hole may be multiple or one, for example. Figure 1 As shown, there are multiple first mounting holes.
[0070] The second connection structure may be a second mounting hole. The second mounting hole may be multiple or one. For example, Figure 1 As shown, there are multiple second mounting holes, and the first mounting holes are equal in size to the second mounting holes.
[0071] The connecting piece may be a screw, a bolt or other types of threaded connecting pieces.
[0072] During the actual implementation, when installing the bearing cover 300 and the bearing base 100, the bearing cover 300 is placed on the upper surface of the bearing base 100, and the elastic member 200 is placed on the bearing cover 300, and the first connecting structure 211 of the installation section 210 of the elastic member 200 corresponds to the second connecting structure of the bearing cover 300, and then the connecting member is passed through the first connecting structure 211 and the second connecting structure in sequence and fixed on the bearing base 100.
[0073] In other embodiments, the first connection structure 211, the second connection structure and the connection member may all be snap-fit members, and the three are connected by snap-fit connection.
[0074] By configuring the first connection structure 211, the second connection structure and the connection piece, the bearing cover 300 and the elastic member 200 can be installed simultaneously using the same connection piece, thereby reducing the number of connection pieces and further reducing the production cost of the shaft 400 assembly.
[0075] In some embodiments, Figure 1 and Figure 3As shown, there are multiple cantilever segments 220 and multiple mounting segments 210 . The multiple cantilever segments 220 are respectively connected to two opposite sides of the contact segment 230 , and the multiple mounting segments 210 are respectively connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 .
[0076] Among them, Figure 1 and Figure 3 As shown, there can be two cantilever sections 220 and two mounting sections 210. The two cantilever sections 220 are respectively located on both sides of the contact section 230 along the length direction of the bearing base 100. The two mounting sections 210 are also respectively located on both sides of the contact section 230 along the length direction of the bearing base 100, and are respectively connected to the cantilever sections 220 located on the same side.
[0077] Since the contact section 230 obtains the force applied to the rotating shaft 400 through the cantilever section 220, providing a plurality of cantilever sections 220 can increase the force applied to the rotating shaft 400 by the contact section 230, thereby improving the stability of the fit between the contact section 230 and the rotating shaft 400. At the same time, by providing a plurality of mounting sections 210, the connection stability between the elastic member 200 and the bearing cover 300 can be improved.
[0078] In other embodiments, the cantilever segments 220 and the mounting segments 210 may also be three, five, six or other numbers, depending on actual conditions.
[0079] In some embodiments, Figure 1 and Figure 3 As shown, the multiple cantilever segments 220 located on both sides of the contact segment 230 are symmetrically arranged relative to the contact segment 230; and / or, the multiple mounting segments 210 connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 are symmetrically arranged relative to the contact segment 230.
[0080] Among them, only the multiple cantilever segments 220 located on both sides of the contact segment 230 can be symmetrically arranged relative to the contact segment 230, or only the multiple mounting segments 210 connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 can be symmetrically arranged relative to the contact segment 230, or the multiple cantilever segments 220 located on both sides of the contact segment 230 can be symmetrically arranged relative to the contact segment 230, and the multiple mounting segments 210 connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 can be symmetrically arranged relative to the contact segment 230, for example. Figure 1 and Figure 3 As shown, the multiple cantilever segments 220 located on both sides of the contact segment 230 are symmetrically arranged relative to the contact segment 230 , and the multiple mounting segments 210 connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 are symmetrically arranged relative to the contact segment 230 .
[0081] like Figure 1 and Figure 3As shown, since the two cantilever sections 220 and the two mounting sections 210 are symmetrically arranged relative to the contact section 230, and the contact section 230 is located at the highest point of the rotating shaft 400, that is, the structures on both sides of the contact section 230 along the length direction of the bearing base 100 are the same, the contact section 230 is subjected to equal forces from the two cantilever sections 220. At this time, the combined force of the forces exerted on the contact section 230 by the two cantilever sections 220 is vertically downward, so that the contact section 230 fits the rotating shaft 400.
[0082] By arranging the multiple cantilever segments 220 located on both sides of the contact segment 230 symmetrically relative to the contact segment 230, and arranging the multiple mounting segments 210 connected to the multiple cantilever segments 220 located on both sides of the contact segment 230 symmetrically relative to the contact segment 230, the stability of the pressure direction to which the contact segment 230 is subjected can be improved, thereby improving the stability of the fit between the contact segment 230 and the rotating shaft 400.
[0083] In some embodiments, Figure 1 As shown, the bearing cover 300 includes a mounting portion 310 and a plurality of limiting portions 320 .
[0084] The mounting portion 310 is mounted on the bearing base 100, and the mounting section 210 is mounted on the mounting portion 310. The shape and structure of the mounting portion 310 may be the same as that of the mounting section 210, or the shape and structure of the mounting portion 310 may be different from that of the mounting section 210. For example, Figure 1 As shown, the shape and structure of the mounting portion 310 are the same as the shape and structure of the mounting section 210 .
[0085] like Figure 1 As shown, there may be two mounting parts 310, the two mounting parts 310 are respectively located on both sides of the arc-shaped groove of the bearing base 100, multiple limiting parts 320 are connected to the mounting parts 310, multiple limiting parts 320 are all located between the two mounting parts 310, and the two ends of the limiting parts 320 are respectively connected to the two mounting parts 310.
[0086] like Figure 1 As shown, the limiting portion 320 and the bearing base 100 define a mounting position 110 . The limiting portion 320 is an arc-shaped structure and cooperates with the bearing base 100 to form the mounting position 110 .
[0087] like Figure 1 As shown, a plurality of limit portions 320 are spaced apart and distributed along the axial direction of the rotating shaft 400, and the contact segment 230 and the cantilever segment 220 are both located between two adjacent limit portions 320, and the axial width of the contact segment 230 and the cantilever segment 220 along the rotating shaft 400 is smaller than the spacing between two adjacent limit portions 320, so that the contact segment 230 and the cantilever segment 220 can directly contact the rotating shaft 400 at the gap between two adjacent limit portions 320.
[0088] By arranging the contact section 230 and the cantilever section 220 between two adjacent limiting portions 320, the elastic member 200 can be installed in the space originally required for installing the shaft 400, thereby reducing the overall volume and occupied space of the shaft 400 assembly, and further reducing the overall weight of the shaft 400 assembly.
[0089] An embodiment of the present application further provides a central control display screen, which includes a display device and a rotating shaft 400 assembly such as any one of the above, and the rotating shaft 400 assembly is installed on the display device.
[0090] According to the central control display screen provided in the embodiment of the present application, by adopting any of the above-mentioned shaft 400 components, the friction between the elastic member 200 and the shaft 400 can be increased, thereby reducing the speed of the shaft 400 during rotation, reducing the unexpected rotation of the shaft 400 under vibration and impact, and improving the safety of the user. In addition, the cost of the elastic member 200 is relatively low, which can help reduce the production cost of the vehicle.
[0091] An embodiment of the present application also provides a vehicle, which includes a center console and a center control display screen as described above, and the center control display screen is installed on the center console.
[0092] According to the vehicle provided in the embodiment of the present application, by adopting any of the above-mentioned central control display screens, the friction between the elastic member 200 and the rotating shaft 400 can be increased, thereby reducing the speed of the rotating shaft 400 during rotation, reducing the unexpected rotation of the rotating shaft 400 under the action of vibration and impact, and improving the safety of the user. In addition, the cost of the elastic member 200 is relatively low, which can help reduce the production cost of the vehicle.
