Description

Technical Field

[0001] The invention belongs to the field of automobile seat structures, and in particular relates to a split flip-type light armrest cup holder frame. Background Art

[0002] The rear center armrest of a car is a common seat mechanism that can improve the riding comfort of rear passengers. The armrest is generally a flip-up structure. When folded, it serves as part of the backrest of the rear center seat; when flipped forward and opened to a horizontal position, it forms an armrest. The armrest is often integrated with a cup holder assembly for placing items such as tea cups. The cup holder assembly can be fixed on the armrest, and the cup holder can be used directly when the armrest is opened; or it can be a sliding hidden design that only slides out when in use. The former design has a simple structure but slightly poor aesthetics, while the latter improves aesthetics but has a complex structure. With the development trend of lightweight automobiles, the lightweighting of automobile seat frames is an important part of the lightweighting of the entire vehicle, and its ways include using lightweight materials and reducing the use of connectors. For the armrest cup holder frame, in order to ensure its strength and reduce the use of connectors, assembly and welding processes, etc., it is necessary to consider the mechanical properties and production process and optimize the overall structural design. Summary of the invention

[0003] In view of this, the present invention provides a split flip-type lightweight armrest cup holder frame.

[0004] The technical solution is as follows:

[0005] A split flip-type light armrest cup holder frame, the key of which is that it includes an armrest frame and a cup holder frame, both of which are in the shape of rectangular plates, and both ends of the two are respectively a connecting end and a free end, the cup holder frame is located on one side of the armrest frame, the free end of the cup holder frame and the free end of the armrest frame face the same direction, and the connecting end of the cup holder frame is hinged to the armrest frame to allow the cup holder frame to be folded and pressed against the corresponding surface of the armrest frame, or to be unfolded relative to the armrest frame.

[0006] The advantage of adopting the above design is that the armrest frame and the cup holder frame can be flipped separately. When used in the rear seat of the vehicle, since the armrest frame is small, the cup holder can be opened separately without opening the armrest, which is beneficial to reduce the space occupied in the rear row. In addition, the armrest frame and the cup holder frame are separately formed with lightweight metal and then assembled to avoid welding connection, bolt connection, etc., and are suitable for lightweight metal processing technology.

[0007] As a preferred technical solution, the armrest frame comprises a plate-shaped armrest frame body, a hinged bracket is fixedly provided on one side of the armrest frame body facing the cup holder frame, and the hinged bracket is close to the connection end of the armrest frame body;

[0008] The cup holder frame comprises a rectangular cup holder body, a connecting end of which is provided with an articulated seat, and the articulated seat corresponds to the articulated bracket;

[0009] The hinge seat and the hinge bracket are provided with a same hinge shaft.

[0010] The above design facilitates the connection between the cup holder frame and the armrest frame.

[0011] As a preferred technical solution, the armrest frame body comprises a first plane portion, a curved surface portion, and a second plane portion connected in sequence from the free end to the connection end, wherein the second plane portion is located outside the plane where the first plane portion is located;

[0012] The hinge bracket is connected to one end of the first plane portion close to the curved surface portion, the hinge bracket extends away from the first plane portion and deviates toward the second plane portion, and a rotation limiting area is formed between the hinge bracket and the curved surface portion;

[0013] A flip limit plate is fixedly provided at the connecting end of the cup holder body, and the flip limit plate rotates in the rotation limit area. When the cup holder frame is unfolded relative to the armrest frame, the flip limit plate abuts against the side of the hinged bracket facing the curved surface portion.

[0014] The above design is adopted because when the armrest and the cup holder are all folded to the backrest position, they constitute a part of the seat backrest. At this time, the armrest frame and the cup holder frame are both in a vertical position, and the cup holder frame is located in front of the armrest frame. When the cup holder frame is folded, the cup holder frame is flush with the second plane portion or slightly higher than the second plane portion, so that the two surfaces are roughly flush. This design can improve riding comfort and avoid excessive reliance on the foam part to achieve a smooth transition between the cup holder and the armrest. In addition, the design of the rotation limit area and the flip limit plate prevents the cup holder frame from excessive rotation.

[0015] As a preferred technical solution, one of the hinged brackets is respectively arranged on both sides close to the handrail frame body, and the two hinged brackets are parallel and opposite to each other;

[0016] A hinge seat is provided on each side of the connecting end of the cup holder body, and the two hinge seats are respectively located outside the two hinge brackets;

[0017] The flip limiting plate is connected between the two hinge seats.

[0018] The above design is helpful to keep the cup holder frame rotating smoothly.

[0019] As a preferred technical solution, the above-mentioned hinged bracket includes a strip-shaped support plate, one end of which is fixedly connected to the handrail frame body, and the other end of the support plate extends away from the handrail frame body and deviates from the connecting end of the handrail frame body, and the extended end of the support plate is fixedly provided with a hinge block;

[0020] A reinforcing rib is connected between the hinge block and the armrest frame body, and the reinforcing rib is arranged along the support plate and connected thereto.

[0021] By adopting the above design, the reinforcing ribs and the supporting plates form a space frame structure, which can be designed to be thinner while ensuring strength.

[0022] As a preferred technical solution, the reinforcing rib is located on the side of the support plate facing away from the rotation limit area, and the reinforcing rib smoothly extends from the hinge block to the armrest frame body and gradually widens;

[0023] There are at least two reinforcing ribs, all of which are arranged along the hinge axis, and the distance between two adjacent reinforcing ribs gradually increases from the hinge block to the handrail frame body.

[0024] With the above design, since the cup holder is opened, especially when loading objects, the closer it is to the armrest body, the greater the shear stress of the support plate, so the reinforcing ribs are gradually widened, and the reinforcing ribs arranged axially along the pin shaft hole strengthen the hinge block as a whole. When approaching the armrest body, the spacing between the reinforcing ribs increases, so that the force on the armrest body is dispersed and the load-bearing capacity is better.

[0025] As a preferred technical solution, the above-mentioned flip limit plate is arranged along the connecting end of the cup holder body, and a hinge seat is provided at each of its two ends;

[0026] The hinge seat comprises a rotating block, which is fixedly arranged at the corresponding end of the flip limit plate, and a rotating hole is penetrated through the rotating block;

[0027] The two rotating holes are arranged on the same hole center line, and a hinge shaft is movably inserted into the rotating hole, and the hinge shaft is inserted into the corresponding hinge bracket.

[0028] With the above design, the rotating block, the flip limit plate and the cup holder body have simple structures and can be integrally formed.

[0029] As a preferred technical solution, a stiffening plate is connected between the rotating block and the flip limit plate, and the stiffening plate extends to and is connected to the cup holder body.

[0030] The above design improves the connection strength between the rotating block and the flip limit plate.

[0031] As a preferred technical solution, there are at least two stiffening plates, all of which are arranged in parallel and perpendicular to the flip limit plate;

[0032] A thinning groove is provided on the outer wall of the rotating block outside the stiffening plate.

[0033] With the above design, the design of the stiffening plate facilitates demoulding after mold forming, and the thinning grooves provided on the rotating block can reduce the possibility of defects due to large wall thickness during mold forming.

[0034] As a preferred technical solution, the above-mentioned articulated shaft is a self-extruding screw, and the rod of the self-extruding screw is composed of two parts, wherein the part close to its front end is a threaded rod, and the part close to the screw head is a smooth rod, the threaded rod is inserted into the articulated bracket and cooperates with its thread, the smooth rod is movably inserted into the articulated seat, and the outer cover of the smooth rod is provided with a noise reduction sleeve.

[0035] The above design facilitates the assembly connection between the cup holder frame and the armrest frame.

[0036] Compared with the prior art, the present invention has the following beneficial effects: the armrest frame and the cup holder frame can be flipped separately. When used in the rear seat of a vehicle, since the armrest frame is small, the cup holder can be opened separately without opening the armrest, which is beneficial to reducing the space occupied in the rear row. Moreover, the two frames are formed separately to adapt to the processing technology of the material itself. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present invention is further described below in conjunction with embodiments and drawings.

[0051] like Figures 1-2 As shown, a split flip-type light armrest cup holder frame includes an armrest frame 100 and a cup holder frame 200, both of which are in the shape of rectangular plates, and both ends of the two are respectively a connecting end and a free end, the cup holder frame 200 is located at one side of the armrest frame 100, the free end of the cup holder frame 200 and the free end of the armrest frame 100 face the same direction, and the connecting end of the cup holder frame 200 is hinged to the armrest frame 100 to allow the cup holder frame 200 to be folded against the corresponding surface of the armrest frame 100, or to be unfolded relative to the armrest frame 100.

[0052] The armrest frame 100 includes a plate-shaped armrest frame body, and a hinge bracket 110 is fixedly provided on one side of the armrest frame body facing the cup holder frame 200, and the hinge bracket 110 is close to the connecting end of the armrest frame body. The cup holder frame 200 includes a rectangular cup holder frame body, and a hinge seat 210 is provided at the connecting end of the cup holder frame body, and the hinge seat 210 corresponds to the hinge bracket 110, and the hinge seat 210 and the hinge bracket 110 are provided with the same hinge shaft 300.

[0053] When installed on the rear seat of the car and in a folded state, the free ends of the armrest frame 100 and the cup holder frame 200 are both facing upward, and the connecting end of the armrest frame 100 is hinged to the seat base below.

[0054] like Figures 4 to 6As shown, the armrest frame body includes a first plane portion 101, a curved surface portion 102 and a second plane portion 103 connected in sequence from the free end to the connection end, and the second plane portion 103 is located outside the first plane portion 101. The purpose of this design is that when the cup holder frame 200 is folded, the cup holder frame 200 is flush with the second plane portion 103 or slightly higher than the second plane portion 103, so that the two surfaces have a smooth transition. Since the armrest and the cup holder are all folded to the backrest position, they constitute a part of the seat backrest. At this time, the armrest frame 100 and the cup holder frame 200 are both in a vertical position, and their free ends are both facing upward, and the cup holder frame 200 is located in front of the armrest frame 100. Therefore, the above design can improve the riding comfort and avoid excessive reliance on the foam part to make the cup holder and the armrest transition smoothly.

[0055] The hinge bracket 110 is connected to one end of the first plane portion 101 close to the curved surface portion 102. The hinge bracket 110 extends away from the first plane portion 101 and deviates toward the second plane portion 103. A rotation limit zone 120 is formed between the hinge bracket 110 and the curved surface portion 102. To ensure the stable installation of the cup holder frame 200, one hinge bracket 110 is respectively provided on both sides close to the armrest frame body, and the two hinge brackets 110 are parallel and directly opposite.

[0056] The edge of the handrail frame body is provided with a continuous reinforcing flange 104, and the reinforcing flange 104 and the hinge bracket 110 are located on the same side of the handrail frame body. A reinforcing edge strip 105 is provided on the handrail frame body near the reinforcing flange 104, and the reinforcing edge strip 105 is parallel to the reinforcing flange 104 adjacent thereto, and the reinforcing edge strip 105 and the reinforcing flange 104 are located on the same side of the handrail frame body, and an edge reinforcing rib is connected between the reinforcing edge strip 105 and the reinforcing flange 104.

[0057] The two surfaces of the handrail body are respectively integrally formed with mesh-distributed reinforcing ribs, the reinforcing ribs are in a cross grid or honeycomb shape, and the area between any two adjacent reinforcing ribs is open to the corresponding surface of the handrail body. The first plane portion 101 is provided with an X-shaped reinforcing protrusion 106, and each end of the X-shaped reinforcing protrusion 106 is close to the corresponding edge of the first plane portion 101.

[0058] The above structures all increase the strength of the handrail frame.

[0059] A safety belt clearance notch 130 is formed at a side edge of the free end of the first plane portion 101 .

[0060] The second plane portion 103 is provided with base connection blocks 107 on both sides of the end portion corresponding to the connection end of the handrail frame body, and the base connection block 107 is connected to the reinforcing flange 104, and a bolt hole 108 is provided on the base connection block 107. A flip limit groove 109 is provided on the base connection block 107, and the notch direction of the flip limit groove 109 is opposite to the direction of the reinforcing flange 104, and the flip limit groove 109 passes out of the corresponding reinforcing flange 104.

[0061] like Figure 4 and 7 As shown, the articulated bracket 110 includes a strip-shaped support plate 111, one end of which is fixedly connected to the handrail frame body, and the other end of which extends away from the handrail frame body and deviates toward the connecting end of the handrail frame body, and a hinge block 112 is fixedly provided at the extended end of the support plate 111. The hinge block 112 is cylindrical, and a pin shaft hole 114 is passed through the center of the hinge block 112, and the hole center line of the pin shaft hole 114 is parallel to the handrail frame body.

[0062] A reinforcing rib 117 is connected between the hinge block 112 and the armrest body. The reinforcing rib 117 is arranged along the support plate 111 and connected thereto. The reinforcing rib 117 is perpendicular to the armrest body. The reinforcing rib 117 is located on the side of the support plate 111 facing away from the rotation limit zone 120. The reinforcing rib 117 smoothly extends from the hinge block 112 to the armrest body and gradually widens. This is because after the cup holder frame 200 is installed, especially when the cup holder frame 200 is unfolded and load-bearing, at this time, if Figure 2 As shown, the free end of the armrest frame 100 faces upward, the cup holder frame 200 is in a horizontal position, and the upper part of the connection between the hinged bracket 110 and the armrest frame body is subjected to tension. Therefore, the reinforcing rib 117 is arranged above the support plate 111, and the reinforcing rib 117 is perpendicular to the armrest frame body to withstand shear force, thereby improving the strength of the hinged bracket 110.

[0063] Furthermore, there are at least two reinforcing ribs 117, all of which are arranged along the hinge axis 300, and the distance between two adjacent reinforcing ribs 117 gradually increases from the hinge block 112 to the armrest body, so as to further improve the connection strength between the support plate 111 and the armrest body.

[0064] In this embodiment, there are three reinforcing ribs 117 , wherein the middle reinforcing rib 117 is connected to the middle of the hinge block 112 , and the other two reinforcing ribs 117 are connected to both ends of the hinge block 112 .

[0065] In addition, a protruding ring 113 is provided at the outer end of the hinge block 112 corresponding to the pin shaft hole 114 , the inner hole of the protruding ring 113 is connected with the pin shaft hole 114 , and the thickness of the protruding ring 113 is smaller than the wall thickness of the pin shaft hole 114 in the inner part of the hinge block 112 .

[0066] like Figures 8 to 11 As shown, the cup holder body includes a quadrilateral frame 230, the inner hole of the frame 230 is provided with a longitudinal strip 231 and a transverse strip 232, the longitudinal strip 231 and the transverse strip 232 are cross-arranged, and the two ends of the longitudinal strip 231 and the transverse strip 232 are respectively connected to the frame 230 to divide the inner hole of the frame 230 into four cup holder box mounting holes 233. The cross-sections of the frame 230, the longitudinal strip 231 and the transverse strip 232 are all groove-shaped, and the grooves face any side of the cup holder body. The longitudinal strip is provided with a weight-reducing hole.

[0067] The end of the cup holder body away from the flip limit plate 220 is fixedly connected to a foam member fixing plate 240, and an open locking member installation box 241 is provided at the edge of the foam member fixing plate 240 away from the cup holder body. The locking member installation box 241 is subsequently used to install a locking member therein, and the locking member is connected to the hanging member on the first plane portion 101 of the armrest frame.

[0068] A flip limit plate 220 is fixedly provided at the connection end of the cup holder body. The flip limit plate 220 is provided along the connection end of the cup holder body. The flip limit plate 220 is lower than the side of the cup holder body facing the armrest frame 100. One of the hinge seats 210 is fixedly provided at each end of the flip limit plate 220. Two hinge seats 210 are located on the side of the flip limit plate 220 facing the armrest frame 100. Rotation holes 212 are respectively penetrated on the two hinge seats 210. The center lines of the two rotation holes 212 are collinear, and the center lines of the two rotation holes 212 are parallel to any one side surface of the cup holder body.

[0069] When the cup holder frame 200 is assembled with the armrest frame 100, the two hinge seats 210 are respectively located outside the two hinge brackets 110. The flip limit plate 220 rotates in the rotation limit area 120. When the cup holder frame 200 is unfolded relative to the armrest frame 100, the flip limit plate 220 abuts against the side of the hinge bracket 110 facing the curved surface 102. The flip limit plate 220 is provided with a reinforcing ridge 221 along its length direction. The reinforcing ridge 221 is close to the side of the flip limit plate 220 away from the cup holder body. The flip limit plate 220 is provided with a weight reduction hole, which is close to the cup holder body.

[0070] The hinge seat 210 includes a rotating block 211, which is fixedly arranged at the corresponding end of the flip limit plate 220, and a rotating hole 212 is penetrated on the rotating block 211. The two rotating holes 212 are arranged on the same hole center line. A stiffening plate 214 is connected between the rotating block 211 and the flip limit plate 220, and the stiffening plate 214 extends to the cup holder body and is connected thereto. There are at least two stiffening plates 214, all of which are arranged in parallel and perpendicular to the flip limit plate 220 and the hole center line of the rotating hole 212, and a thinning groove 213 is provided on the outer wall of the rotating block 211 outside the stiffening plate 214.

[0071] The articulated bracket 110 corresponds to the rotating block 211 one by one, and the rotating block 211 protrudes from the corresponding stiffening plate 214 on one side of the inner end corresponding to the rotating hole 212, and the extending ring 113 is located between the articulated block 112 and the rotating block 211, so that the contact area between the two is reduced and the rotation friction is reduced.

[0072] In this embodiment, the hinge shaft 300 is a self-squeezing screw. Fig.12 and 13 As shown, the self-extruding screw includes a screw cap 301 and a rod. The rod of the self-extruding screw consists of two parts, wherein the part near the front end is a threaded rod 303, and the part near the screw head is a smooth rod 302. The cross section of the threaded rod 303 is a rounded triangle, and its cross section is surrounded by three arc-shaped edges. The thread teeth of the threaded rod 303 are triangular thread teeth. Figure 3 As shown, the threaded rod 303 is inserted into the hinged bracket 110 and matched with its thread, the smooth rod 302 is movably inserted into the rotating hole 212, and the smooth rod 302 is covered with a noise reduction sleeve 400 made of polymer material.

[0073] The armrest frame 100 and the cup holder frame 200 are formed in one piece by using a mold, and then the pin hole 114 whose inner diameter is smaller than the outer diameter of the threaded rod 303 is processed on the hinge block 112 of the armrest frame 100, and then assembled by self-extrusion screws. The armrest frame 100 is made of light metal such as magnesium alloy and aluminum alloy, and its hardness is smaller than that of the self-extrusion screw, but its plastic deformation ability is relatively strong. During assembly, the threaded rod 303 of the self-extrusion screw enters the hinge block 112 from the pin hole 114 and squeezes its inner wall. Compared with the circular thread, the triangular thread has both cutting and squeezing deformation effects, so that the threaded rod 303 is firmly connected with the hinge block 112, preventing the cup holder from loosening due to flipping during use, and the assembly is very simple.

[0074] The structural design of the armrest frame 100 and the cup holder frame 200 facilitates bidirectional demoulding along the direction perpendicular to the armrest frame body or the cup holder frame body. For the armrest frame 100, since the angle between the hinge bracket 110 and the armrest frame body is an acute angle, a slider is used for demoulding.

[0075] The width of the cup holder body decreases gradually from the connecting end to the free end thereof, the maximum width of the cup holder body does not exceed the width of the armrest body, and the length of the cup holder body is less than the length of the armrest body. After the foam parts and other necessary components are installed on the armrest frame 100 and the cup holder frame 200, they are rotatably connected to the seat base through the base connecting block 107. When the armrest is flipped forward to open, the flip limit groove 109 on the armrest frame 100 plays a limiting role. The armrest frame provided in this embodiment is convenient for the occupant to open the cup holder assembly forward alone while keeping the armrest in a locked state. Since the cup holder occupies a small space, it occupies less space after opening; it is also possible to keep the cup holder and the armrest relatively locked and flip the armrest to open.

[0076] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
