Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to an armrest box hinge assembly and a vehicle. Background Art

[0002] In modern automotive design, the center console armrest is a crucial component, often used to store small items and provide a comfortable experience for the driver and passengers. The opening and closing of the armrest typically relies on hinge structures, which need to be strong and durable enough to withstand frequent use.

[0003] In the prior art, a hinge is located between a fixed part and a rotating part of a hinge structure. When installed in an armrest box, the fixed part is fixedly connected to the box body, and the rotating part is connected to the box lid, making the lid easy to open and close. When the armrest box is closed, the hinge is exposed to the interior space of the armrest box. Frequent opening and closing of the armrest box to store items can easily cause dust, dirt, and other impurities to enter between the hinge parts of the hinge structure, causing wear and damage to the hinge, thereby affecting its service life and performance.

[0004] In view of this, an embodiment of the present application provides an armrest box hinge assembly and a vehicle, which protect the hinge part through a hinge cover to prevent dust, dirt and other impurities from invading the hinge part, thereby extending the service life of the hinge part.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] On the one hand, an embodiment of the present application provides an armrest box hinge assembly, comprising:

[0007] The hinge assembly includes: a hinge sleeve and a hinge part, the hinge sleeve is provided with a rack surrounding a first rotation axis, and the hinge part is fixedly arranged on the hinge sleeve; a box bracket, the box bracket and the hinge part are pivotally matched around the first rotation axis, the box bracket is provided with a damping gear, and the damping gear is engaged with the rack so that the hinge assembly can rotate around the first rotation axis relative to the box bracket.

[0008] The armrest hinge assembly of this utility model, by placing the hinge member in the hinge cover, is not exposed to the environment during the armrest opening and closing process, effectively preventing the intrusion of dust, dirt, and other impurities into the hinge member, thereby extending the service life of the hinge member. The coordination between the damping gear and the rack makes the opening and closing process of the armrest box smoother, improving the user experience.

[0009] In one possible implementation, the hinge cover includes: a first base and first rotating parts located on opposite sides of the first base along a first direction, and the racks are formed on the sides of the two first rotating parts facing each other; the hinge member includes a second base and second rotating parts located on opposite sides of the second base along the first direction; the first base and the second base are fixedly connected; the two second rotating parts correspond to the two first rotating parts one by one and are arranged relative to each other, and the two second rotating parts are respectively located on the inner sides of the two first rotating parts.

[0010] In this way, the hinge member and the hinge cover are fixedly connected by the fixed connection between the first base and the second base, thereby improving the structural reliability of the hinge assembly.

[0011] In a possible implementation, one of the first substrate and the second substrate is provided with a positioning structure, and the other is provided with a positioning and matching structure, and the first substrate and the second substrate are connected via the positioning structure and the positioning and matching structure.

[0012] In this way, through the coordinated connection between the positioning structure and the positioning matching structure, the positioning accuracy of the first base and the second base during the installation process is improved, thereby improving the structural stability of the hinge assembly.

[0014] In this way, the cooperation between the positioning column and the positioning hole not only facilitates the installation between the first base and the second base, but also provides a fixing effect when the positioning column is passed through the positioning hole, preventing the connection between the hinge sleeve and the hinge part from loosening, thereby improving the stability of the hinge assembly.

[0015] In a possible implementation, the end of the second rotating portion away from the second base has a first pivot connection portion protruding toward the first rotation axis, the first pivot connection portion is provided with a first pivot hole penetrating along the first direction, the box bracket is provided with a second pivot connection portion corresponding one-to-one to the first pivot connection portion, and the second pivot connection portion is provided with a second pivot hole penetrating along the first direction.

[0016] The hinge assembly further includes a pivot shaft, and the hinge member and the box bracket are connected by the pivot shaft passing through the first pivot hole and the second pivot hole.

[0018] In a possible implementation, there is one pivot shaft, and the pivot shaft passes through the two first pivot holes of the hinge member and the two second pivot holes of the box bracket respectively.

[0019] This single pivot axis ensures synchronization and coordination between the hinge and the case frame during opening and closing, preventing jamming or noise caused by asynchrony between multiple pivot axes and improving the user experience. A single pivot axis passes through both the first and second pivot holes, providing a stronger mechanical connection and enhancing the stability of the structural connection between the hinge assembly and the case frame. This prevents loosening or detachment during use, improving durability.

[0020] In one possible implementation, the end of the first rotating part away from the first base has a third pivot connection part protruding toward the first rotation axis, and the third pivot connection part is provided with a third pivot hole passing through along the first direction, and the pivot shaft is also passed through the third pivot hole.

[0021] The design of the third pivot connection ensures synchronization and coordination between the first and second rotating parts and the case bracket during opening and closing, avoiding jamming or unusual noises caused by asynchrony between multiple connections and enhancing the user experience. The pivot axis simultaneously passes through the first, second, and third pivot holes, creating a multi-point fixed connection, further enhancing the overall stability of the hinge assembly, preventing loosening or detachment of the connection between the hinge assembly and the case bracket during use, and improving the durability of the hinge assembly.

[0022] In one possible implementation, a first through hole is provided on the first pivot connection portion, and the first through hole is radially spaced apart from the first pivot hole; the hinge assembly also includes a spring member, which is sleeved on the pivot shaft, and the two ends of the spring member are respectively passed through the first through holes on the two first pivot connection portions.

[0023] The spring element allows the armrest cover to automatically return to its original position or remain in its designated position after opening, providing an elastic reset function and enhancing user convenience and experience. Furthermore, the spring element absorbs and cushions external impact and vibration during the opening and closing of the armrest cover, reducing direct impact on the hinge assembly and protecting it and internal components, thereby extending the life of the hinge assembly.

[0055] In the prior art, a hinge is located between a fixed part and a rotating part of a hinge structure. When installed in an armrest box, the fixed part is fixedly connected to the box body, and the rotating part is connected to the box lid, making the lid easy to open and close. When the armrest box is closed, the hinge is exposed to the interior space of the armrest box. Frequent opening and closing of the armrest box to store items can easily cause dust, dirt, and other impurities to enter between the hinge parts of the hinge structure, causing wear and damage to the hinge, thereby affecting its service life and performance.

[0056] In view of this, an embodiment of the present application provides an armrest box hinge assembly and a vehicle, which protect the hinge part through a hinge cover to prevent dust, dirt and other impurities from invading the hinge part, thereby extending the service life of the hinge part.

[0057] First, embodiments of the present application provide an armrest hinge assembly. The armrest hinge assembly can be used in a vehicle, which can include large cars, small cars, special-purpose vehicles, and the like. For example, based on the power type, the vehicle in this application can be a pure electric vehicle, a hybrid vehicle, a fuel vehicle, and the like.

[0058] refer to Figures 1 to 9 The armrest box hinge assembly 100 may include a hinge assembly 110 and a box support 120. The armrest box body and the box cover are connected via the armrest box hinge assembly 100. The box support 120 is fixedly connected to the box body. The hinge assembly 110 is connected to the box cover. When the box cover is opened, the hinge assembly 110 rotates relative to the box support 120 about a first rotation axis.

[0059] The hinge assembly 110 may include a hinge cover 111 and a hinge part 112. The hinge cover 111 is provided with a rack 111a surrounding the first rotation axis. The hinge part 112 is fixed to the hinge cover 111, so that the hinge assembly 110 forms an integral structure, which is easy to install, replace and maintain.

[0060] A damping gear 121 is provided on the box bracket 120, and the damping gear 121 is engaged with the rack 111a. When the box lid is opened, the hinge assembly 110 rotates around the first rotation axis relative to the box bracket 120, and the damping gear 121 is engaged and rotated with the rack 111a, making the opening and closing process of the box lid smoother. In addition, through the cooperation between the damping gear 121 and the rack 11a, the box lid can stay at any angle during the opening and closing process without automatically closing, which is convenient for users to take and put items.

[0061] It can be understood that in this embodiment, due to the meshing transmission between the rack 111a of the hinge guard 111 and the damping gear 121 of the box bracket 120, the hinge guard 111 and the hinge member 112 are fixedly connected, and the hinge member 112 is pivotally engaged with the box bracket 120. Therefore, when the rack 111a rotates relative to the damping gear 121, the hinge guard 111 can drive the hinge member 112 to rotate relative to the box bracket 120 about the first axis. The mutual cooperation among the hinge guard 111, the hinge member 112, and the box bracket 120 improves the synchronization and reliability of the operation of the armrest box hinge assembly 100.

[0062] The armrest hinge assembly 100 of the present invention, by locating the hinge member 112 within the hinge sheath 111, protects the hinge member 112 from exposure to the environment during the armrest opening and closing process, effectively preventing dust, dirt, and other impurities from entering the hinge member 112, thereby extending the service life of the hinge member 112. The coordination between the damping gear 121 and the rack 111a makes the armrest opening and closing process smoother, enhancing the user experience.

[0063] refer to Figures 1 to 4 In some embodiments, the hinge cover 111 may include a first base 111b and two first rotating parts 111c. The first base 111b may be substantially plate-shaped. The two first rotating parts 111c are respectively located on the first base 111b along the first direction (such as Figure 1 On opposite sides of the first rotating portion 111c (in the X direction shown), racks 111a are formed on the sides facing each other. Correspondingly, damping gears 121 are provided on both sides of the box support 120 to mesh with the racks 111a. This improves the stability of the rotational cooperation between the hinge cover 111 and the box support 120.

[0064] The hinge 112 may include a second base 112a and two second rotating parts 112b. The second base 112a may be substantially plate-shaped. The two second rotating parts 112b are respectively located on opposite sides of the second base 112a along the first direction to match with the first rotating part 111c.

[0065] The first base 111b and the second base 112a are fixedly connected. For example, the first base 111b and the second base 112a can be fixed by welding, or the first base 111b and the second base 112a can be fixed by screws, or the first base 111b and the second base 112a can be fixed by clamping.

[0066] The two second rotating portions 112 b correspond to the two first rotating portions 111 c one by one and are arranged opposite to each other. The two second rotating portions 112 b are respectively located on the inner sides of the two first rotating portions 111 c.

[0067] The hinge member 112 and the hinge cover 111 are fixedly connected, which improves the structural reliability of the armrest hinge assembly 100. In addition, the hinge cover 111 is located on the inner side of the hinge member 112, which protects it from external dust, dirt and other impurities, thereby extending the service life of the armrest hinge assembly 100.

[0068] refer to Figure 2 and Figure 4 According to some embodiments of the present invention, one of the first base 111b and the second base 112a is provided with a positioning structure 113, and the other is provided with a positioning and matching structure 114. For example, the first base 111b is provided with the positioning structure 113, and the second base 112a is provided with the positioning and matching structure 114, or the first base 111b is provided with the positioning and matching structure 114, and the second base 112a is provided with the positioning structure 113.

[0069] The first base 111b and the second base 112a are connected via the positioning structure 113 and the positioning and matching structure 114, which improves the positioning accuracy of the first base 111b and the second base 112a during installation, thereby improving the structural stability of the hinge assembly 110. In addition, the coordination between the positioning structure 113 and the positioning and matching structure 114 makes the assembly process of the hinge assembly 110 simpler and faster, reducing the complexity and time cost of the hinge assembly 110 and improving production efficiency.

[0070] Continue to refer Figure 2 and Figure 4 According to some embodiments of the present invention, a positioning column 111d is provided on the first base 111b, and the positioning column 111d is arranged along the second direction (such as Figure 1The second base 112a extends in the Z direction (as shown), and the positioning post 111d constitutes the aforementioned positioning structure 113. The second base 112a is provided with a positioning hole 112c, which penetrates the second base 112a along the second direction and constitutes a positioning and mating structure 114. The positioning post 111d is inserted into the positioning hole 112c, so that the first base 111b and the second base 112a are stacked in the second direction to form an integrated hinge assembly 110.

[0071] The axial hole cooperation between the positioning column 111d and the positioning hole 112c not only facilitates the installation between the first base 111b and the second base 112a, but also the cooperation between the positioning column 111d and the positioning hole 112c provides a fixing effect, preventing the connection between the hinge cover 111 and the hinge part 112 from loosening, thereby improving the stability of the hinge assembly 110.

[0072] refer to Figure 2 、 Figure 3 and Figure 4 According to some embodiments of the present invention, the second rotating portion 112b has a first pivot connection portion 112d at one end away from the second base 112a, and the first pivot connection portion 112d protrudes toward the first rotation axis. The first pivot connection portion 112d is provided with a first pivot hole 112e, and the first pivot hole 112e passes through the first pivot connection portion 112d along the first direction. The box bracket 120 is provided with a second pivot connection portion 122, and the second pivot connection portion 122 corresponds to the first pivot connection portion 112d one-to-one. The second pivot connection portion 122 is provided with a second pivot hole 123, and the second pivot hole 123 passes through the second pivot connection portion 122 along the first direction. The armrest box hinge assembly 100 may also include a pivot shaft 130, which passes through the first pivot hole 112e and the second pivot hole 123 to connect the hinge member 112 and the box bracket 120. In this way, a reliable mechanical connection is provided for the box bracket 120 and the hinge assembly 110, the stability of the armrest box hinge assembly 100 is enhanced, and the connection between the hinge assembly 110 and the box bracket 120 is prevented from loosening or falling off during use.

[0073] refer to Figure 1 、 Figure 2 and Figure 8 According to some embodiments of the present invention, the pivot shaft 130 may be one, and the pivot shaft 130 passes through the two first pivot holes 112e of the hinge member 112 and the two second pivot holes 123 of the box bracket 120 respectively.

[0074] On the one hand, the connection through a pivot shaft 130 ensures the synchronization and coordination of the hinge 112 and the box bracket 120 during the opening and closing process, avoiding jamming or abnormal noise caused by the asynchrony of multiple pivot shafts 130, and improving the user experience. On the other hand, a pivot shaft 130 passes through the two first pivot holes 112e and the two second pivot holes 123 at the same time, providing a more reliable mechanical connection, enhancing the stability of the connection structure between the hinge assembly 110 and the box bracket 120, and preventing the connection between the hinge assembly 110 and the box bracket 120 from loosening or falling off during use, thereby improving the durability of the armrest box hinge assembly 100.

[0075] refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 According to some embodiments of the present invention, the first rotating portion 111c has a third pivoting portion 111e at one end away from the first base 111b. The third pivoting portion 111e protrudes toward the first rotation axis. A third pivot hole 111f is defined in the third pivoting portion 111e. The third pivot hole 111f extends through the third pivoting portion 111e in the first direction, and the pivot shaft 130 is also disposed in the third pivot hole 111f.

[0076] Thus, the design of the third pivot connection 111e ensures synchronization and coordination between the first rotating portion 111c, the second rotating portion 112b, and the box bracket 120 during opening and closing, avoiding jamming or abnormal noise caused by asynchrony of multiple connections, and improving the user experience. By simultaneously passing the pivot shaft 130 through the first pivot hole 112e, the second pivot hole 123, and the third pivot hole 111f, a multi-point fixed connection is formed, further enhancing the overall stability of the hinge assembly 110, preventing the connection between the hinge assembly 110 and the box bracket 120 from loosening or falling off during use, and improving the durability of the armrest box hinge assembly 100.

[0077] refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8According to some embodiments of the present invention, a first through hole 112f is provided on the first pivot connection portion 112d, and the first through hole 112f is radially spaced apart from the first pivot hole 112e. The armrest hinge assembly 100 may further include a spring member 140, which is sleeved on the pivot shaft 130, and the two ends of the spring member 140 are respectively passed through the first through holes 112f on the two first pivot connection portions 112d. By providing the spring member 140, on the one hand, the spring member 140 enables the armrest cover to automatically reset or remain in the set position after opening, providing an elastic reset function for the armrest, thereby improving the user's convenience and experience. On the other hand, the spring member 140 can absorb and buffer external impact force and vibration during the opening and closing process of the armrest cover, reducing direct impact on the hinge assembly 110, protecting the hinge assembly 110 and internal components, and thus extending the service life of the armrest hinge assembly 100.

[0078] Optionally, a second through hole can be provided on each of the two third pivot connection parts 111e, and the second through hole is coaxially arranged with the first through hole 112f. After the two ends of the spring member 140 pass through the first through hole 112f respectively, they can also be passed through the second through hole. In this way, the hinge cover 111 and the hinge member 112 are subjected to force synchronously, thereby improving the force stability of the hinge assembly 110.

[0079] refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the pivot shaft 130 may include a rod 130a and a head 130b. The head 130b is provided at one end of the rod 130a and abuts against a side of one of the first pivot connections 112d facing away from the box bracket 120. The rod 130a passes through the two first pivot connections 112d, and a slot 130c is provided at one end of the rod 130a away from the head 130b. The slot 130c is located on a side of the other first pivot connection 112d away from the box bracket 120. The armrest box hinge assembly 100 may further include a rotating shaft anti-slip member 150. The rotating shaft anti-slip member 150 is disposed in the slot 130c and abuts against a side of the first pivot connection 112d away from the box bracket 120.

[0080] The head portion 130b of the pivot shaft 130 abuts against the side of one of the first pivot connection portions 112d facing away from the box support 120, while the shaft anti-slip member 150 is located on the side of the other first pivot connection portion 112d facing away from the box support 120. This provides a dual fixation, improves the connection stability of the pivot shaft 130, and prevents the pivot shaft 130 from loosening or shifting during use. Furthermore, the installation method in which the shaft anti-slip member 150 cooperates with the retaining groove 130c also simplifies the installation and removal of the pivot shaft 130, reduces the number of installation steps and installation time for the pivot shaft 130, and improves production efficiency.

[0081] refer to Figure 9 The operating principle of the armrest box hinge assembly 100 of the present invention is:

[0082] When the armrest box lid is closed, the spring member 140 rotates and tightens to store force. When the armrest box lid is opened, the spring member 140 releases the stored force, and the damping gear 121 meshes with the rack 111a to drive the armrest box lid to open, and when it reaches the limit point, it reaches the corresponding angle and hovers.
