Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a novel automotive seat armrest. Background Technology

[0002] Car seat armrests are functional components installed on the sides or center of seats to provide arm support for occupants, primarily improving seating comfort by distributing arm pressure. As the automotive industry upgrades towards intelligence and high-end features, seat armrests have evolved from simple support components into comprehensive carriers integrating human-computer interaction, storage, and charging functions. They are widely used in passenger vehicles (especially mid-to-high-end sedans and SUVs) and commercial vehicles, becoming a key component in enhancing vehicle interior quality and user experience.

[0003] Currently, to achieve multi-functionality within limited armrest space, the rigidity and strength of the seat armrest are generally sacrificed. When the pressure of the arm is concentrated on a single point on the armrest, it can easily cause deformation, such as sagging of the top crossbar. Furthermore, existing armrest frames are typically directly mounted on the seat cushion side panels, requiring continuous remodeling of the side panels during actual production, significantly increasing costs. Moreover, existing seat armrests are prone to swaying due to resonance during vehicle operation, affecting ride comfort and failing to meet users' demands for a high-quality driving experience.

[0004] Therefore, there is an urgent need to design a new type of car seat armrest that can significantly improve the rigidity and strength of the armrest while achieving a high degree of functional integration. This effectively avoids problems such as armrest deformation and sagging of the top crossbar, thus improving user comfort and convenience. Simultaneously, it can directly utilize the existing seat cushion side panel structure, eliminating the need for remodeling, significantly reducing mold costs and parts costs, and balancing structural reliability and economy. Furthermore, it effectively avoids swaying and resonance issues, and combined with a high-rigidity frame structure, ensures the stability of the armrest under complex road conditions, providing occupants with a superior driving and riding experience.

[0008] In a preferred embodiment of this application, the device further includes a touchscreen, a USB port, and a phone storage slot; the touchscreen is mounted on the touchscreen mounting plate; the USB port and the phone storage slot are arranged sequentially from top to bottom on the outer protective plate and are located on the front side of the armrest frame; the outer surface of the phone storage slot is also provided with soft rubber.

[0009] In a preferred embodiment of this application, an armrest connecting bracket is also included; the armrest connecting bracket is disposed on the side plate of the seat cushion and is fixedly connected to the side plate of the seat cushion.

[0010] In a preferred embodiment of this application, the armrest connecting bracket includes a first connecting bracket, a second connecting bracket, a third connecting bracket, and a fourth connecting bracket; the first connecting bracket is fixedly disposed on the rear end side of the seat cushion side panel; the second connecting bracket is engaged in the middle of the seat cushion side panel; the third connecting bracket is disposed on the front end side of the seat cushion side panel; and the fourth connecting bracket is disposed at the bottom end of the seat cushion side panel for fixed connection with the front vertical tube.

[0011] In a preferred embodiment of this application, the rear vertical tube support is provided with a plug-in block; one end of the plug-in block is fixed to the rear vertical tube support, and the other end is bent upward and outward, and the whole is inverted L-shaped; the side plate of the seat cushion is provided with a plug-in through hole that matches the plug-in block.

[0012] In a preferred embodiment of this application, the first connecting bracket, the third connecting bracket, and the fourth connecting bracket are each provided with a threaded through hole; the second connecting bracket is provided with two threaded through holes, and the two threaded through holes are symmetrically arranged on both sides of the insertion through hole; the armrest frame is fixed to the seat cushion side plate by bolts passing through the five threaded through holes respectively.

[0013] In a preferred embodiment of this application, the first connecting bracket is vertically disposed at one end of the seat cushion side plate, and the first connecting bracket is also provided with a fastening screw hole, the fastening screw hole and the threaded through hole being respectively disposed at the upper end and the lower end of the first connecting bracket; the first connecting bracket is fixedly connected to the rear vertical tube by means of a bolt passing through the fastening screw hole.

[0014] The technical solution provided in this application has the following beneficial effects:

[0015] (1) The novel automotive seat armrest provided in this application includes an armrest frame and an outer protective plate. When an occupant places their arm on the armrest, the upper horizontal tube of the armrest frame first bears the pressure, and then transmits the pressure to the front and rear vertical tubes. The pressure is then dispersed through the rear vertical tube support, forming a circular force transmission. This allows the entire armrest frame to bear the load evenly, reducing problems such as armrest frame deformation caused by stress concentration. Simultaneously, by setting the armrest frame as a closed U-shaped frame, when the armrest is subjected to lateral torque under pressure, the closed U-shaped frame forms torsional stiffness, preventing the frame from twisting along the axis, thereby further improving the stiffness and stability of the armrest frame. Setting the mounting plate support as a zigzag shape allows for the dispersion and transmission of load through multiple turning points, reducing deformation or damage caused by concentrated force, further improving the overall structural stability, and thus providing better support. Compared to existing armrest structures, the solution provided in this application can significantly improve the rigidity and strength of the seat armrest while achieving a high degree of functional integration. It effectively avoids problems such as armrest deformation and sagging of the top crossbar, thereby improving user comfort and convenience.

[0016] (2) By directly welding the first, third, and fourth connecting brackets to the seat cushion side panel, and then snapping the second connecting bracket onto the seat cushion side panel, and providing five threaded through holes on the armrest connecting bracket, the armrest connecting bracket and the armrest frame can be fixedly connected by bolts passing through the threaded through holes, thereby fixing the armrest frame to the seat cushion side panel. In this process, there is no need to re-molde the seat cushion side panel; the armrest frame can be fixed to the existing seat cushion side panel through the armrest connecting bracket, greatly reducing costs. At the same time, by providing fastening screw holes on the first connecting bracket, compared with the five-bolt connection method, the cantilever can be further shortened, the connection rigidity can be increased, and the natural frequency can be changed, so that the natural frequency of the seat armrest is staggered from the resonant frequency of the vehicle body, effectively avoiding coupling resonance caused by close frequencies, and greatly improving comfort. Compared to existing armrest structures, the solution provided in this application can directly adopt the existing seat cushion side panel structure without remodeling the seat cushion side panel, which greatly reduces mold costs and parts costs, and balances structural reliability and economy; moreover, it can effectively avoid swaying and resonance problems, and with the high rigidity frame structure, it ensures the stability of the armrest under complex road conditions, providing passengers with a better driving experience.

[0026] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0027] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0028] Currently, in order to achieve multiple functions within a limited armrest space, the rigidity and strength of the seat armrest are generally sacrificed. When the pressure of the arm is concentrated on a certain point on the armrest, it is easy to cause deformation of the armrest, such as the top crossbar sagging.

[0029] To address the aforementioned issues, this application provides a novel automotive seat armrest that significantly improves the rigidity and strength of the armrest while achieving a high degree of functional integration. This effectively prevents issues such as armrest deformation and sagging of the top crossbar, thereby enhancing user comfort and convenience.

[0030] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figures 1-5The novel car seat armrest of this application includes an armrest frame 1, an outer protective plate 2, a touch screen 3, a USB interface 4, and a mobile phone storage slot 5. The outer protective plate 2 is arranged around the outside of the armrest frame 1. The touch screen 3, the USB interface 4, and the mobile phone storage slot 5 are arranged sequentially from top to bottom on the outer protective plate 2 and are located on the front side of the armrest frame 1.

[0033] Specifically, the handrail frame 1 includes an upper horizontal tube 11, a front vertical tube 12, a rear vertical tube 13, and a rear vertical tube support 14. The front vertical tube 12 and the rear vertical tube 13 are parallel and vertically arranged, and the top ends of the front vertical tube 12 and the rear vertical tube 13 are fixedly connected to both ends of the upper horizontal tube 11, and the bottom ends are fixedly connected to the rear vertical tube support 14, so that the upper horizontal tube 11, the front vertical tube 12, the rear vertical tube 13, and the rear vertical tube support 14 form a U-shaped frame. By setting the handrail frame 1 as a closed U-shaped frame, when it is subjected to force, the force can be transmitted to the entire frame (i.e., the force is transmitted in a ring), forming a synergistic resistance, thereby significantly reducing the deformation of individual members and effectively solving problems such as frame deformation, such as the sagging of the top horizontal bar, in existing structures.

[0034] like Figure 1 As shown, to increase the comfort of the seat armrests, the outer panel 2 is further provided with a layer of skin 10, and armrest foam is provided at the hand support position. The armrest foam is located under the skin. To better install the touch screen 3 and facilitate occupant operation, the armrest frame 1 also includes a touch screen mounting plate 15. The touch screen mounting plate 15 is made of sheet metal, and one end of the touch screen mounting plate 15 is fixedly connected to the top of the front vertical tube 12, while the other end extends forward and diagonally upward. The touch screen 3 is mounted on the touch screen mounting plate 15. By tilting the touch screen mounting plate 15 forward and upward, it better aligns with the occupant's line of sight, allowing the occupant to operate the touch screen 3.

[0035] Furthermore, to provide better support for the touchscreen 3, the armrest frame 1 also includes a mounting plate support 16. The mounting plate support 16 is made of steel wire, and one end of the mounting plate support 16 is fixedly connected to the front end of the touchscreen mounting plate 15, while the other end is fixedly connected to the bottom end of the front vertical tube 12. Preferably, as shown... Figure 2 As shown, the mounting plate support 16 is generally zigzag-shaped, and it has mounting holes to facilitate subsequent wiring harness installation. By framing the mounting plate support 16 as a zigzag shape, the load can be distributed and transferred through multiple turning points, reducing deformation or damage caused by concentrated stress, improving the overall stability of the structure, and thus providing better support.

[0036] To effectively prevent damage to the phone stored in the phone storage slot 5 due to vibration and impact, the new car seat armrest also includes soft rubber, which is applied to the outer surface of the phone storage slot 5. By using soft rubber, cushioning is increased, thereby protecting the phone from impact damage.

[0037] In this first embodiment, the novel automotive seat armrest provided by this application includes an armrest frame and an outer protective plate. When an occupant places their arm on the armrest, the upper horizontal tube of the armrest frame first bears the pressure, then transmits the pressure to the front and rear vertical tubes, and then disperses the pressure through the rear vertical tube support, forming a circular force transmission. This allows the entire armrest frame to bear the load evenly, reducing problems such as armrest frame deformation caused by stress concentration. Simultaneously, by setting the armrest frame as a closed U-shaped frame, when the armrest is subjected to lateral torque under pressure, the closed U-shaped frame forms torsional stiffness, preventing the frame from twisting along the axis, thereby further improving the stiffness and stability of the armrest frame. Setting the mounting plate support as a zigzag shape can disperse and transmit the load through multiple turning points, reducing deformation or damage caused by concentrated force, further improving the overall stability of the structure, and thus providing better support. Compared to existing armrest structures, the solution provided in this application can significantly improve the rigidity and strength of the seat armrest while achieving a high degree of functional integration. It effectively avoids problems such as armrest deformation and sagging of the top crossbar, thereby improving user comfort and convenience.

[0038] Example 2

[0039] Existing armrests are typically mounted directly on the seat cushion side panels, requiring the side panels to be remodeled during production, significantly increasing costs. Furthermore, existing seat armrests are prone to wobbling due to resonance during vehicle operation, affecting ride comfort and failing to meet users' demands for a high-quality driving experience. To address these issues, this application proposes a corresponding solution; please refer to [link / reference]. Figures 1-5 Specifically:

[0040] Based on the structure of Embodiment 1 above, the novel car seat armrest provided in Embodiment 2 of this application further includes an armrest connecting bracket 6. The armrest connecting bracket 6 is disposed on the seat cushion side plate 9 and fixedly connected to the seat cushion side plate 9. Specifically, the armrest connecting bracket 6 includes a first connecting bracket 61, a second connecting bracket 62, a third connecting bracket 63, and a fourth connecting bracket 64. The first connecting bracket 61 is fixedly disposed on the rear end side of the seat cushion side plate 9, the second connecting bracket 62 is snapped into the middle of the seat cushion side plate 9, the third connecting bracket 63 is disposed on the front end side of the seat cushion side plate 9, and the fourth connecting bracket 64 is disposed on the bottom end of the seat cushion side plate 9 for fixed connection with the front vertical tube 12. The first connecting bracket 61, the third connecting bracket 63, and the fourth connecting bracket 64 are all connected to the seat cushion side plate 9 by welding.

[0041] More specifically, to facilitate rapid positioning and assembly, the rear vertical tube bracket 14 is provided with a plug-in block 141; one end of the plug-in block 141 is fixed to the rear vertical tube bracket 14, and the other end is bent upward and outward, forming an inverted L shape. The seat cushion side plate 9 is provided with a plug-in through hole 91 that matches the plug-in block 141; by inserting the plug-in block 141 into the plug-in through hole 91, the function of rapid positioning and assembly is achieved. Further, in order to fix the armrest frame 1 and the armrest connecting bracket 6, the first connecting bracket 61, the third connecting bracket 63, and the fourth connecting bracket 64 are each provided with a threaded through hole 7; the second connecting bracket 62 is provided with two threaded through holes 7, and the two threaded through holes 7 are symmetrically arranged on both sides of the plug-in through hole 91. Correspondingly, the armrest frame 1 is also provided with five threaded through holes 7, and the armrest frame 1 is fixed to the seat cushion side plate 9 by bolts passing through the five threaded through holes 7 respectively.

[0042] Furthermore, to address the issue of seat armrests wobbling due to resonance during vehicle operation, the first connecting bracket 61 is vertically positioned at one end of the seat cushion side panel 9. The first connecting bracket 61 also includes a fastening screw hole 8, which, along with the threaded through hole 7, is located at the upper and lower ends of the first connecting bracket 61, respectively. Correspondingly, the rear vertical tube 13 also has a fastening screw hole 8. Bolts are passed through the fastening screw holes 8 to securely connect the first connecting bracket 61 to the rear vertical tube 13. By providing the fastening screw hole 8, the cantilever can be further shortened, increasing connection rigidity and causing a change in the natural frequency. This causes the natural frequency of the seat armrest to be offset from the resonant frequency of the vehicle body, effectively preventing coupling resonance caused by close frequencies and significantly improving comfort.

[0043] It should be noted that, in order to facilitate the connection between the handrail frame 1 and the handrail connecting bracket 6, the handrail frame 1 further includes a front vertical tube bracket 17. The front vertical tube bracket 17 is disposed at the lower end of the front vertical tube 12 and is fixedly connected to the front vertical tube 12. The front vertical tube bracket 17 is provided with a threaded through hole 7, and the fourth bracket is fixedly connected to the front vertical tube bracket 17 by bolts passing through the bolt through hole.

[0044] In Embodiment 2 of this application, the novel automotive seat armrest further includes an armrest connecting bracket. By directly welding the first, third, and fourth connecting brackets to the seat cushion side panel, and then snapping the second connecting bracket onto the seat cushion side panel, and providing five threaded through holes on the armrest connecting bracket, a fixed connection between the armrest connecting bracket and the armrest frame can be achieved by passing bolts through these threaded through holes. This fixes the armrest frame to the seat cushion side panel. In this process, there is no need to re-molde the seat cushion side panel; the armrest frame can be fixed to the existing seat cushion side panel using the armrest connecting bracket, significantly reducing costs. Simultaneously, by providing fastening screw holes on the first connecting bracket, compared to a five-bolt connection, the cantilever can be further shortened, increasing connection rigidity and causing a change in the natural frequency. This causes the natural frequency of the seat armrest to be offset from the resonant frequency of the vehicle body, effectively avoiding coupling resonance caused by close frequencies and greatly improving comfort. Compared to existing armrest structures, the solution provided in this application can directly adopt the existing seat cushion side panel structure without remodeling the seat cushion side panel, which greatly reduces mold costs and parts costs, and balances structural reliability and economy; moreover, it can effectively avoid swaying and resonance problems, and with the high rigidity frame structure, it ensures the stability of the armrest under complex road conditions, providing passengers with a better driving experience.
