Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle handrail hinge, handrail, and vehicle. Background Technology

[0002] In the field of automotive interior human-machine interaction, the armrest box, as a functional component frequently touched by drivers and passengers, directly impacts the user experience due to the ease of operation and safety of its opening mechanism. In existing technologies, automotive armrests typically employ a hinged connection structure, with the armrest cover connected to the main body via a hinge assembly. Users must press a switch to trigger a spring-driven mechanism to open the armrest cover. However, this traditional design suffers from the following significant technical drawbacks:

[0003] The current armrest opening process involves two stages: "spring opening - manual rotation." After the spring unfolds, the armrest cover needs to reach equilibrium with its weight to maintain a stable, slightly open state (typically 8°-30°). Furthermore, the opening angle relies entirely on the passive balance between the spring stiffness and the armrest cover's gravitational torque, lacking an active control mechanism. The spring force is significantly affected by factors such as ambient temperature and material creep, resulting in opening angle deviations of up to ±15° between different batches of products or even the same product at different usage periods, severely impacting the consistency of the armrest cover's opening angle. If the armrest opens too high, it can easily collide with the user's hand, affecting the user experience. Utility Model Content

[0004] To solve, or at least partially solve, the aforementioned technical problems, the primary objective of this utility model is to provide a vehicle armrest hinge. An auxiliary hinge frame is added to the hinge, connecting a pivot and an elastic element on a fixed frame. A limiting part is provided on the fixed frame. When the armrest cover is unlocked, the elastic element uses its elastic potential energy to drive the auxiliary hinge frame to rotate. The limiting part restricts the auxiliary hinge frame to only drive the pivot and the armrest cover hinge frame to rotate by a first preset angle, thereby opening the armrest cover by a first preset angle. This ensures the consistency of the armrest cover opening angle across the vehicle, prevents the armrest cover from popping up too high and injuring the user, and improves the user experience.

[0005] The second objective of this invention is to provide a handrail.

[0006] The third objective of this utility model is to provide a vehicle.

[0007] The first aspect of this utility model provides a vehicle armrest hinge, comprising:

[0008] A fixing frame, wherein the fixing frame is provided with an elastic element and a limiting part;

[0009] The armrest cover hinge frame is rotatably mounted on the fixed frame via a pivot. The armrest cover hinge frame has a locked state and an unlocked state. When the armrest cover hinge frame is in the locked state, the elastic element has elastic potential energy.

[0010] An auxiliary hinge frame is fixedly connected to the rotating shaft at one end and to the elastic element at the other end. When the armrest cover hinge frame is in the unlocked state, the elastic element drives the auxiliary hinge frame and the armrest cover hinge frame to rotate synchronously until the auxiliary hinge frame abuts against the limiting part, so that the armrest cover hinge frame opens to a first preset angle.

[0011] Furthermore, the armrest cover hinge frame is provided with a main hinge hole, and at least a portion of the structure in the main hinge hole abuts against the outer peripheral wall of the rotating shaft, so as to realize that the armrest cover hinge frame rotates synchronously with the rotating shaft;

[0012] After the armrest cover hinge frame opens to the first preset angle, the armrest cover hinge frame can overcome the friction between the main hinge hole and the rotating shaft under the action of external force, so as to rotate relative to the rotating shaft and open to the second preset angle.

[0013] Furthermore, the rotating shaft has an abutment portion, and the main hinge hole has a protrusion portion. The protrusion portion abuts against the abutment portion, and when the protrusion portion is subjected to external force, it can overcome the frictional force between itself and the abutment portion and pass over the abutment portion, so that the armrest cover hinge frame rotates relative to the rotating shaft.

[0014] Furthermore, the rotating shaft includes a connected round shaft section and a flat shaft section, the round shaft section being rotatably mounted on the fixed frame, and the flat shaft section being matched and connected to the auxiliary hinge frame;

[0015] The main hinge hole is a round hole and is fitted outside the flat shaft section. The abutting part is an angular structure of the flat shaft section, which abuts against the protrusion on the inner wall of the main hinge hole.

[0016] Furthermore, the fixing frame includes a fixed hinge arm, the rotating shaft is rotatably mounted on one end of the fixed hinge arm, and the limiting part is disposed on the fixed hinge arm and is disposed opposite to the auxiliary hinge frame.

[0017] Furthermore, the limiting part includes a limiting plate that is laterally disposed on the fixed hinge arm, and the auxiliary hinge frame has a limiting block for abutting against the limiting plate;

[0018] And / or, the connection between the limiting plate and the fixed hinge arm is provided with reinforcing ribs.

[0019] Furthermore, the fixing frame includes a fixing bracket, the fixing hinge arms are disposed opposite to each other at the top two ends of the fixing bracket, the elastic element and the auxiliary hinge frame are respectively installed on both sides of the fixing hinge arm, and the other end of the auxiliary hinge frame extends downward beyond the fixing hinge arm and is hinged to one end of the elastic element.

[0020] And / or, the fixing frame includes a mounting shaft installed between the two ends of the fixing bracket, and the elastic element is a torsion spring sleeved on the mounting shaft.

[0021] Furthermore, the other end of the auxiliary hinge frame forms a connecting portion, which is recessed away from the armrest cover hinge frame and forms a clearance space between the armrest cover hinge frame and the armrest cover hinge frame. One end of the elastic member passes through the connecting portion and is located within the clearance space.

[0022] The second aspect of this utility model provides an armrest, which includes an armrest box, an armrest cover, and any of the hinges described above, wherein the armrest cover is rotatably mounted on the armrest box via the hinge.

[0023] The third aspect of this utility model provides a vehicle including any of the armrest hinges or armrests described above.

[0024] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0025] (1) This utility model adds an auxiliary hinge frame to the armrest hinge. The auxiliary hinge frame connects the rotating shaft and the elastic element on the fixed frame. A limiting part is provided on the fixed frame. When the armrest cover is unlocked, the elastic element drives the auxiliary hinge frame to rotate through its elastic potential energy. The limiting part restricts the auxiliary hinge frame to only drive the rotating shaft and the armrest cover hinge frame to rotate by a first preset angle, thereby opening the armrest cover by a first preset angle. This ensures the consistency of the opening angle of the vehicle's armrest cover, avoids the armrest cover from popping up too high and injuring the user when it is opened, and improves the user experience.

[0026] (2) When the armrest cover is opened to the first preset angle under the drive of the auxiliary hinge frame, if the armrest cover is subjected to force to overcome the frictional force of contact with the pivot, the armrest cover hinge can continue to rotate relative to the pivot and open to the second preset angle, so that the armrest cover can be opened to the second preset angle, making it convenient for the user to take out the items inside the armrest box.

[0043] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0045] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0046] like Figures 1 to 7 As shown, an embodiment of this utility model provides a vehicle armrest hinge, which allows the armrest cover to be rotatably mounted on the armrest box or vehicle body structure via the hinge, for closing or opening the armrest box opening.

[0047] The handrail hinge includes a fixed frame 2, a handrail cover hinge frame 1, and an auxiliary hinge frame 5.

[0048] The fixed frame 2 is provided with a limiting part 212, and a retractable elastic element 4 is installed on the fixed frame 2. The armrest cover hinge frame 1 is rotatably mounted on the fixed frame 2 via a pivot 3. The armrest cover hinge frame 1 has a locked state and an unlocked state. When the armrest cover hinge frame 1 is in the locked state, the elastic element 4 has elastic potential energy, which can be the potential energy generated by compression or stretching.

[0049] One end of the auxiliary hinge frame 5 is fixedly connected to the rotating shaft 3, and the other end of the auxiliary hinge frame 5 is connected to the elastic element 4. When the armrest cover hinge frame 1 is in the unlocked state, the elastic element 4 drives the auxiliary hinge frame 5 and the armrest cover hinge frame 1 to rotate synchronously until the auxiliary hinge frame 5 abuts against the limiting part 212, so that the armrest cover hinge frame 1 opens to the first preset angle.

[0050] It should be noted that during the opening of the armrest cover hinge frame 1 to the first preset angle, both the armrest cover hinge frame 1 and the auxiliary hinge frame 5 are fixedly connected in the circumferential direction relative to the pivot 3. When the hinge is applied to the vehicle armrest, the armrest cover hinge frame 1 is fixed to the armrest cover, and the fixing frame 2 is fixed to the armrest box or the vehicle body structure. The armrest cover hinge frame 1 and the auxiliary hinge frame 5 can rotate relative to the fixing frame 2.

[0051] This utility model adds an auxiliary hinge frame 5 to the armrest hinge. The auxiliary hinge frame 5 connects the rotating shaft 3 and the elastic element 4 on the fixed frame 2. A limiting part 212 is provided on the fixed frame 2. When the armrest cover is unlocked, the elastic element 4 drives the auxiliary hinge frame 5 to rotate through its elastic potential energy. The limiting part 212 restricts the auxiliary hinge frame 5 to only drive the rotating shaft 3 and the armrest cover hinge frame 1 to rotate by a first preset angle, thereby opening the armrest cover by a first preset angle. This ensures the consistency of the opening angle of the vehicle's armrest cover, avoids the armrest cover from popping up too high when opened and injuring the user, and improves the user experience.

[0052] In the above scheme, the elastic element 4 includes a tension spring or a torsion spring, etc.

[0053] like Figures 3 to 7 As shown, the armrest cover hinge frame 1 is provided with a main hinge hole 111. At least a portion of the structure within the main hinge hole 111 abuts against the outer peripheral wall of the rotating shaft 3, so as to realize that the armrest cover hinge frame 1 rotates synchronously with the rotating shaft 3. After the armrest cover hinge frame 1 opens to the first preset angle, under the action of external force, the armrest cover hinge frame 1 can overcome the friction between the main hinge hole 111 and the rotating shaft 3, so as to rotate relative to the rotating shaft 3 and open to the second preset angle.

[0054] This invention involves a portion of the structure within the main hinge hole 111 of the armrest cover hinge frame 1 abutting against the outer peripheral wall of the rotating shaft 3. When the armrest cover hinge frame 1 is in the unlocked state, the auxiliary hinge frame 5, driven by the elastic potential energy of the elastic element 4, rotates the rotating shaft 3. At this time, the transmission force on the rotating shaft 3 cannot overcome the frictional force between the rotating shaft 3 and the main hinge hole 111, causing the armrest cover hinge frame 1 and the rotating shaft 3 to rotate synchronously, opening to a first preset angle. After the armrest cover hinge frame 1 opens to the first preset angle, if the force on the armrest cover hinge frame 1 can overcome the frictional force between the main hinge hole 111 and the rotating shaft 3, the armrest cover hinge frame 1 can continue to rotate relative to the rotating shaft 3, opening to a second preset angle, allowing the armrest cover to open to the second preset angle, facilitating the user to retrieve items inside the armrest box.

[0055] It should be noted that the first and second preset angles of rotation of the armrest cover hinge frame 1 are both relative to the angles of rotation when the armrest cover hinge frame 1 is in the locked state, with the second preset angle being greater than the first preset angle. Furthermore, after the armrest cover hinge frame 1 opens to the first preset angle, the armrest cover hinge frame 1 is subjected to an external force that overcomes the friction between the main hinge hole 111 and the rotating shaft 3. During this process, the external force can be the user's manual force of pulling the armrest cover upwards, or it can be the driving force of other cooperating automatic moving modules that drive the armrest cover or the armrest cover hinge frame 1 to rotate.

[0056] The first preset angle is 5° to 20°, and the second preset angle is 80° to 150°. The specific angle can be set according to actual needs. This embodiment is only an example and is not intended to impose specific limitations. Preferably, the first preset angle is 10° and the second preset angle is 90°.

[0057] like Figures 4 to 7 As shown, the rotating shaft 3 has an abutment portion 3121, and a protrusion 112 is provided on the main hinge hole 111. The protrusion 112 abuts against the abutment portion 3121, and when the protrusion 112 is subjected to an external force, it can overcome the frictional force between itself and the abutment portion 3121 and pass over the abutment portion 3121, so that the armrest cover hinge frame 1 rotates relative to the rotating shaft 3.

[0058] The rotating shaft 3 can be entirely round, with a micro-protrusion structure on one component of the round shaft and the main hinge hole 111, which abuts against the other component of the round shaft and the main hinge hole 111 to generate friction. The rotating shaft 3 can also include a non-round shaft section.

[0059] like Figure 4 and Figure 6 As shown, the rotating shaft 3 includes a pin 31 and a nut 32. The pin 31 passes through the fixing frame 2, the auxiliary hinge frame 5 and the handrail cover hinge frame 1 in sequence, and is then fixedly connected by the nut 32.

[0060] The pin 31 includes at least a round shaft section 311 and a flat shaft section 312. The round shaft section 311 is rotatably mounted on the fixed frame 2, and the flat shaft section 312 is matched and connected to the auxiliary hinge hole 514 of the auxiliary hinge frame 5. The flat shaft section 312 refers to a shaft section with a non-circular cross-section.

[0061] The pin 31 also includes a limiting shaft section 313 and a threaded shaft section 314. The limiting shaft section 313 is coaxially connected to the round shaft section 311, and the threaded shaft section 314 is coaxially connected to the flat shaft section 312. That is, the pin 31 includes the limiting shaft section 313, the round shaft section 311, the flat shaft section 312, and the threaded shaft section 314, which are coaxially connected in sequence. The limiting shaft section 313 abuts against the inner side of the fixed hinge arm 21 to prevent the pin 31 from dislodging from the pivot hole 211. The round shaft section 311 is rotatably mounted on the pivot hole 211 of the fixed hinge arm 21, and the pivot hole 211 is a round hole that matches the round shaft section 311. The flat shaft section 312 passes through the auxiliary hinge hole 514 of the auxiliary hinge frame 5, and the two are shaped and circumferentially fixed. The threaded shaft section 314 is threadedly connected to the nut 32 to mount the pin 31 on the fixed hinge arm 21.

[0062] The flat shaft segment 312 includes shaft segments with cross-sections of rectangles, rounded rectangles, or combinations of planar and arc surfaces.

[0063] like Figure 5 and Figure 7As shown, the main hinge hole 111 is a round hole and is fitted outside the flat shaft section 312. The abutment part 3121 is an angular structure of the flat shaft section 312, which abuts against the protrusion 112 on the inner wall of the main hinge hole 111.

[0064] When the user pulls the armrest cover upwards, it causes the protrusion 112 of the armrest cover hinge frame 1 to move, overcoming the friction between the protrusion 112 and the abutment 3121, so that the protrusion 112 passes over the abutment 3121, and the armrest cover hinge frame 1 can rotate and open to the second preset angle relative to the flat shaft section 312.

[0065] Specifically, the main hinge hole 111 is a circular hole. The flat shaft section 312 is a flat shaft formed by cutting the opposite sides of the circular shaft into planes. The outer peripheral wall of the flat shaft section 312 includes two planes and two arc surfaces. The abutment part 3121 is located at the connection between the plane and the arc surface of the flat shaft section 312.

[0066] The protrusions 112 are spaced circumferentially on the inner wall of the main hinge hole 111. One end of the protrusion 112 abuts against the abutment 3121, and both ends of the protrusion 112 are gradually raised towards the middle in the extension direction, so as to facilitate the protrusion 112 passing over the abutment 3121 after being subjected to force.

[0067] like Figures 1 to 2 as well as Figure 6 As shown, the fixing frame 2 includes a fixing bracket 22 and a fixing hinge arm 21. The fixing hinge arms 21 are spaced apart and opposite to each other at both ends of the top of the fixing bracket 22 along a first direction. (See reference 2017 for the first direction). Figure 3 The pivot 3 is rotatably mounted on one end of the fixed hinge arm 21, and the limiting part 212 is provided on the fixed hinge arm 21 and is disposed opposite to the auxiliary hinge frame 5. It should be noted that the limiting part 212 is located on one side of the rotation direction of the auxiliary hinge frame 5, so that the auxiliary hinge frame 5 can abut against the limiting part 212 after rotation.

[0068] The limiting part 212 includes a limiting plate that is laterally disposed on the fixed hinge arm 21, and a limiting block 513 on the auxiliary hinge frame 5 for abutting against the limiting plate. The limiting block 513 has a limiting surface that matches and abuts against the limiting plate.

[0069] A reinforcing rib 213 is provided at the connection between the limiting plate and the fixed hinge arm 21 to enhance the connection strength between the limiting plate and the fixed hinge arm 21. Preferably, the reinforcing rib 213 is a pressed structure. A bent structure is formed at the connection between the fixed hinge arm 21 and the limiting plate, and a bent reinforcing plate 214 is provided on the inner side of the bent structure to further enhance the connection strength between the limiting plate and the fixed hinge arm 21.

[0070] Furthermore, the fixed hinge arms 21 are positioned opposite each other at the top of the fixed bracket 22. The elastic element 4 and the auxiliary hinge frame 5 are respectively installed on both sides of the fixed hinge arms 21. One end of the auxiliary hinge frame 5 is connected to the fixed hinge arm 21 through the pivot 3. The other end of the auxiliary hinge frame 5 extends downward beyond the fixed hinge arm 21 and is hinged to one end of the elastic element 4. When the elastic element 4 releases its elastic potential energy and generates displacement, it drives the other end of the auxiliary hinge frame 5 to move synchronously, causing the auxiliary hinge frame 5 to rotate around the mounting point of the fixed hinge arm 21. This allows the movement trajectories of the elastic element 4 and the auxiliary hinge frame 5 to avoid each other in space, effectively solving the interference problem that may occur between the two during movement.

[0071] The armrest cover hinge frame 1 includes a connecting bracket 12 and a rotating hinge arm 11 connected sequentially along a second direction. (See the second direction section.) Figure 3 The first direction is perpendicular to the second direction. Rotating hinge arms 11 are spaced apart and positioned opposite each other at both ends of the connecting bracket 12 along the first direction, located inside or outside the fixed hinge arm 21, depending on actual production needs. Starting from the connecting bracket 12, the rotating hinge arm 11 extends downwards along a first arc trajectory to its lowest point, and then extends upwards along a second arc trajectory to its end point, its overall structural shape resembling a U-shape.

[0072] The fixed hinge arm 21 extends upward at an angle from the top of the fixed bracket 22 away from the connecting bracket 12.

[0073] Preferably, the elastic element 4 is located inside the fixed hinge arm 21 and mounted on the fixed bracket 22. The auxiliary hinge frame 5 and the armrest cover hinge frame 1 are both located outside the fixed hinge arm 21. The auxiliary hinge frame 5 is located between the armrest cover hinge frame 1 and the fixed hinge arm 21, which makes reasonable use of space and facilitates the installation of each component.

[0074] A partition sleeve 6 is provided between the auxiliary hinge frame 5 and the armrest cover hinge frame 1, which is fitted on the pivot 3, so that the auxiliary hinge frame 5 and the armrest cover hinge frame 1 are spaced apart.

[0075] The other end of the auxiliary hinge frame 5 forms a connecting part 511. The connecting part 511 is recessed to the side away from the armrest cover hinge frame 1 and forms a clearance space between it and the armrest cover hinge frame 1. One end of the elastic member 4 passes through the connecting part 511 and is located in the clearance space.

[0076] The fixing frame 2 includes a mounting shaft 23, which is located between the two ends of the fixing bracket 22 in the first direction. The elastic element 4 is a torsion spring sleeved on the mounting shaft 23, and the two ends of the torsion spring are respectively mounted on the fixing bracket 22 and the connecting part 511 located on both sides of the mounting shaft 23 in the axial direction.

[0077] Specifically, the fixed bracket 22 includes a fixed plate 221 and side plates 222. The side plates 222 are spaced apart and opposite to each other at both ends of the fixed plate 221 along a first direction, and the side plates 222 and the fixed plate 221 are connected at an angle. The fixed hinge arm 21 extends obliquely upward from the top of the side plate 222. The side plate 222 is provided with a fixing part 2221 for fixing the fixed bracket 2 to the armrest box or the structure of the vehicle body.

[0078] The two ends of the mounting shaft 23 are respectively mounted on the two side plates 222. One end of the torsion spring passes around the side plate 222 and is rotatably snapped onto the connecting part 511, while the other end is snapped into the snap-fit ​​hole 2211 of the fixing plate 221.

[0079] When the armrest cover hinge frame 1 is in the locked state, the two ends of the torsion spring rotate relative to each other with the mounting shaft 23 as the fulcrum, and its winding part generates elastic deformation and stores elastic potential energy. When the armrest cover hinge frame 1 is unlocked and enters the unlocked state, the torsion spring drives the two ends to return to the initial position through the elastic reset action. During this process, the end of the torsion spring near the connecting part 511 generates a rotational motion towards the fixed bracket 22. This rotational motion is transmitted to the connecting part 511 through the hinge point, forming a displacement along an arc trajectory. The displacement of the connecting part 511 drives the auxiliary hinge frame 5 to rotate around its mounting point with the fixed hinge arm 21. The rotation of the auxiliary hinge frame 5 forms a lever effect through the rotating shaft 3, which ultimately drives the armrest cover hinge frame 1 to rise.

[0080] The auxiliary hinge frame 5 includes a hinge plate 51. The upper end of the hinge plate 51 is provided with an auxiliary hinge hole 514. The hinge plate 51 bends away from the rotating hinge arm 11 and extends downward to form a bent connecting part 511. The lower end of the connecting part 511 is provided with a slot 512, which is engaged with one end of a torsion spring.

[0081] The upper end of the hinge plate 51 protrudes to form a limiting block 513 on the side near the connecting bracket 12.

[0082] This utility model also provides an armrest (not shown in the figure), including any of the hinges described above. In addition to supporting the user's arm, the armrest has internal storage space for storing items.

[0083] The armrest includes an armrest box and an armrest cover. The armrest cover is rotatably mounted on the armrest box via a hinge, used to close or open the opening of the armrest box. When the opening of the armrest box is open, the user can take out items inside.

[0084] One end of the armrest cover is fixedly connected to an armrest cover hinge, and the adjacent end of the armrest box is fixedly connected to a fixing bracket. The other end of the armrest cover is provided with a locking hook, which can be locked or unlocked with a locking part on the armrest box.

[0085] When the armrest cover hinge bracket is locked, the armrest cover is in a horizontal or nearly horizontal position. When the armrest cover is opened to the first preset angle, it is in the slightly open position; when the armrest cover is opened to the second preset angle, it is in the fully open position.

[0086] This utility model also provides a vehicle (not shown in the figure) including any of the hinges or handrails described above.

[0087] The vehicle provided in this embodiment of the utility model has the beneficial effects of the hinges or armrests of any of the above embodiments because it includes the hinges or armrests of any of the above embodiments, which will not be described again here.
