Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a handrail structure. It also relates to a vehicle equipped with the handrail structure. Background Technology

[0002] The secondary instrument panel, as an important component of the cockpit's functional area, primarily serves for storage, integrating control buttons, or enhancing interior aesthetics. However, in existing models, the height of the secondary instrument panel's armrest is generally lower than the support required for the driver's elbows when naturally hanging down. Especially for the driver, the gap between the elbow and the armrest in their steering wheel-holding posture results in the forearm being in an unnatural, suspended position for extended periods. This design, especially during long-distance driving, easily leads to driver elbow fatigue due to the lack of effective support, resulting in poor vehicle comfort. Utility Model Content

[0003] In view of this, the present invention aims to provide a handrail structure that can better support the elbows of drivers and passengers, thereby improving driving and riding comfort.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An armrest structure is applied to a sub-dashboard, including a mounting bracket disposed on the sub-dashboard, an armrest body rotatably disposed on the mounting bracket, and a locking mechanism disposed between the armrest body and the mounting bracket;

[0006] The armrest body has a concealed state that is at least partially hidden within the sub-dashboard, and a used state that is rotated out from one side of the sub-dashboard, the locking mechanism being able to lock the armrest body in the used state.

[0007] Furthermore, the locking mechanism has multiple locking positions and is capable of locking the handrail body in different usage states; and / or,

[0008] The locking mechanism includes a pawl rotatably mounted on the handrail body, a ratchet portion mounted on the mounting bracket, and a first elastic member disposed between the pawl and the handrail body. Under the action of the first elastic member, the pawl engages with the ratchet portion and locks the handrail body in the use state.

[0009] Furthermore, the pawl is provided with a guide portion, and the mounting bracket is provided with a mating portion;

[0010] Under the action of the first elastic member, the guide portion abuts against the mating portion, which can guide the pawl to engage with the ratchet portion.

[0011] Furthermore, the mating part includes a mating block disposed above the ratchet portion, the mating block having a first mating surface and a second mating surface located on one side of the first mating surface;

[0012] As the armrest body is rotated out, the first mating surface and the second mating surface abut against the guide portion in sequence, guiding the pawl to engage with the ratchet portion.

[0013] Furthermore, the mounting bracket is provided with a guide groove located above the ratchet portion, and a guide surface located between the guide groove and the ratchet portion;

[0014] The guide surface abuts against the guide portion, which can guide the guide portion into the guide groove and disengage the pawl from the ratchet tooth portion.

[0015] Furthermore, the guide groove is an arc-shaped groove with the rotation center of the armrest body as the center, and the top of the arc-shaped groove extends to the top of the mating part;

[0016] As the armrest body is screwed in, the guide portion can disengage from the top of the guide groove and abut against the mating portion.

[0017] Furthermore, the guide portion includes a guide post inserted into the pawl, and a second elastic member abutting between the guide post and the pawl;

[0018] Under the action of the second elastic element, the guide post abuts against the mounting bracket.

[0019] Furthermore, a limiting part is provided between the mounting bracket and the handrail body, which can limit the rotation angle of the handrail body.

[0020] Furthermore, a damping part is provided between the handrail body and the mounting frame. The damping part can apply resistance to the rotation of the handrail body and keep the handrail body at any position during the rotation process.

[0021] This utility model has the following advantages:

[0022] (1) The armrest structure described in this utility model, by setting the armrest body on the sub-dashboard, allows the armrest body to have both a hidden state and a usable state. Therefore, when not in use, the armrest body can be hidden, effectively preventing interference with the driver and passengers. When in use, the armrest body can be rotated out from one side of the sub-dashboard, bringing it closer to the driver's elbow and supporting it, thus effectively preventing fatigue caused by elbow drooping and improving driving comfort. Simultaneously, the locking mechanism enhances the stability of the armrest body's support for the elbow, resulting in a better overall performance of the armrest structure.

[0023] (2) The locking mechanism has multiple locking positions and can lock the handrail body in different usage states, thus meeting the needs of people of different body types. The locking mechanism consists of a pawl, a ratchet, and a first elastic element. Under the action of the first elastic element, the pawl and the ratchet are tightly engaged, thereby providing a stable locking force to firmly lock the handrail body in the usage state. This effectively prevents the handrail body from accidentally shaking during use, improving the safety of drivers and passengers. Moreover, the structure is simple, which not only facilitates installation and manufacturing but also reduces processing costs and potential failure points.

[0024] (3) By providing a guide portion on the pawl and a mating portion on the mounting bracket, and with the guide portion abutting against the mating portion under the action of the first elastic element, the pawl can be guided to engage with the ratchet teeth. This effectively ensures that the teeth of the pawl engage quickly with the ratchet teeth, allowing the handrail body to be quickly locked in use. Moreover, the preload of the first elastic element keeps the guide portion pressed against the mating portion, further enhancing engagement stability and effectively preventing the pawl from accidentally disengaging due to vehicle vibration or external interference, thereby improving the stability of the handrail body in use.

[0025] (4) The mating part includes a mating block with a first mating surface and a second mating surface, which has a simple structure and is easy to design and implement. Moreover, the first mating surface and the second mating surface can abut against the guide part in sequence during the rotation of the handrail body, making the pawl move more smoothly during the engagement with the ratchet, which helps to ensure the normal operation of the locking mechanism and the reliability of locking. In addition, the mating part also makes the engagement process between the pawl and the ratchet more stable, which can effectively reduce the impact force and shaking generated at the moment of engagement, and help to improve the structural stability of the locking mechanism itself.

[0026] (5) By setting a guide groove on the mounting bracket and a guide surface located between the guide groove and the ratchet part, and making the guide surface abut against the guide part, the pawl can be guided to disengage from the ratchet part. Thus, the driver only needs to apply a small external force to disengage the pawl from the ratchet part, which can improve the unlocking convenience and enhance the operating experience.

[0027] (6) The guide groove is designed as an arc-shaped groove with the rotation center of the handrail body as the center. It can match the rotational movement of the handrail body, which helps to ensure the relative movement coordination between the components and makes the operation of the handrail structure smoother. The top of the arc-shaped groove extends to the top of the mating block. When the handrail body is screwed in, the guide part can disengage from the top of the arc-shaped groove and smoothly abut against the mating part. This facilitates the re-screwing and locking of the handrail body and ensures the smoothness of the handrail body's screwing in and out. As a result, the screwing in and out operation of the handrail body is easier and more convenient.

[0028] (7) The guide part includes a guide post inserted on the pawl and a second elastic member abutting between the guide post and the pawl. Under the action of the second elastic member, the guide post abuts against the mounting bracket. Thus, when the guide post enters the guide groove through the guide surface, it can be inserted into the guide groove under the action of the second elastic member and can have good abutting stability with the groove wall of the guide groove, thereby improving the guiding effect of the guide groove on the guide post.

[0029] (8) By setting a limiting part between the mounting bracket and the handrail body to limit the rotation angle of the handrail body, the handrail body can be effectively prevented from rotating excessively during use, thereby avoiding safety hazards or inconvenience caused by excessive rotation angle.

[0030] (9) By setting a damping part between the handrail body and the mounting bracket, the handrail body can be kept at any position during the rotation process. This can improve the stability of the handrail body in the hidden state, thereby effectively preventing the handrail body from accidentally rotating out due to shaking during driving, thus interfering with the driver's driving operation and effectively reducing the driving safety risk caused by the handrail body accidentally rotating out.

[0031] Another objective of this invention is to provide a vehicle equipped with the handrail structure described above.

[0032] The vehicle described in this utility model, by providing the armrest structure as described above, not only hides the armrest body when not in use, effectively preventing interference with the driver and passengers, but also allows the armrest body to be rotated out from one side of the sub-dashboard when in use, supporting the elbow and thus effectively preventing fatigue caused by elbow drooping, and improving driving comfort.

[0057] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0058] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] In existing technologies, the height of the passenger-side dashboard armrest is generally lower than the support required when the driver's elbow is naturally hanging down. In long-distance driving scenarios, the driver's elbows become fatigued due to the lack of effective support. Moreover, although some models have armrest structures that can support the elbows, most of these armrests are too far from the driver's elbows, resulting in poor support and minimal effect on reducing driver fatigue.

[0060] Therefore, this embodiment proposes a novel armrest structure for use on a sub-dashboard. The armrest structure includes a mounting bracket 3 mounted on the sub-dashboard, an armrest body 1 rotatably mounted on the mounting bracket 3, and a locking mechanism between the armrest body 1 and the mounting bracket 3. The armrest body 1 has a concealed state, at least partially hidden within the sub-dashboard, and a usable state, rotated out from one side of the sub-dashboard. The locking mechanism can lock the armrest body 1 in the usable state.

[0061] The armrest structure of this embodiment, by setting the armrest body 1 on the sub-dashboard, allows the armrest body 1 to have both a hidden and a usable state. Therefore, when not in use, the armrest body 1 can be hidden to prevent interference with the driver and passengers. When in use, the armrest body 1 can be rotated out from one side of the sub-dashboard, bringing it closer to the driver's elbow and supporting it, effectively preventing fatigue caused by elbow drooping and improving driving comfort. Simultaneously, the locking mechanism enhances the stability of the armrest body 1 in supporting the elbow, resulting in a better overall performance of the armrest structure.

[0062] Based on the above overview, an exemplary structure of the handrail in this embodiment can be found in [reference]. Figures 1 to 7 As shown, for ease of understanding, we will first provide a general overview of the structure of the sub-dashboard. Figure 3 As shown, the sub-instrument panel in this embodiment is the same as that in the prior art, and generally includes a sub-instrument panel body 15, a left cover plate 16 located on the left side of the sub-instrument panel body 15, a right cover plate 20 located on the right side of the sub-instrument panel body 15, a center armrest box 17 and a storage box 21 provided on the sub-instrument panel body 15, a rear cover plate 18 provided on the rear side of the sub-instrument panel body, and an upper cover plate 19 provided on the top. Since the improvement points of this embodiment do not involve the improvement of the sub-instrument panel, the structure of the sub-instrument panel will not be described in detail, and the prior art can be referred to.

[0063] In this embodiment, the handrail structure is specifically mounted on the handrail box 17 via the mounting bracket 3, and a through hole for the handrail body 1 to pass through is provided on the left cover plate 16. Furthermore, as... Figure 2 As shown, the through hole is located at the junction of the left cover plate 16 and the upper cover plate 19. To further improve usability, the upper cover plate 19 and the left cover plate 16 are provided with a receiving space to accommodate the armrest body 1, and the side of the armrest body 1 in the concealed state is flush with the side of the sub-dashboard. This not only provides better aesthetics but also prevents the armrest body 1 from protruding and interfering with the driver and passengers.

[0064] In addition, as a specific embodiment, this embodiment has only one armrest structure, and the armrest body 1 can rotate to the left along the left-right direction of the vehicle to be in use and support the driver's elbow. It should be noted that in other embodiments, two armrest structures can also be provided, with the two armrest structures rotating out from the left and right sides of the sub-dashboard respectively, so as to support the elbows of the driver and passenger respectively.

[0065] Specifically, such as Figure 8 As shown, the mounting bracket 3 in this embodiment is generally L-shaped and includes a base plate 3b and a side plate 3a. The armrest body 1 is specifically mounted on the side plate 3a. Here, to facilitate the installation of the mounting bracket 3 on the armrest box 17, as shown... Figure 8 As shown, four protrusions 306 are provided on the base plate 3b, and each protrusion 306 has a mounting hole. The mounting bracket 3 is screwed to the bottom of the armrest box 17 by screws passing through the mounting holes. To further improve the stability of the mounting bracket 3 on the armrest box 17, see [reference needed]. Figure 4 As shown, on the side of the side plate 3a away from the bottom plate 3b, there are two protruding mounting plates 306. At the same time, the mounting bracket 3 is also screwed to the armrest box 17 by screws passing through each mounting plate 306.

[0066] Furthermore, both the side panel 3a and the bottom panel 3b are plate-shaped structures, which occupy less space and are easy to install on the sub-dashboard without causing any difficulties in arrangement. Moreover, installing the bottom panel 3b at the bottom of the armrest box 17 will not affect the structure and function of the armrest box 17 or the covers themselves. Therefore, the armrest structure of this embodiment can be well implemented on the sub-dashboard.

[0067] It should be noted that the structure of mounting bracket 3 is not limited to... Figure 8 As shown, as long as the armrest body 1 can be installed and fixed to the armrest box 17, it is sufficient. In addition, the mounting bracket 3 can be connected to the armrest box 17 by screwing through the base plate 3b and the mounting plate 306, or it can be connected to the armrest box 17 by other conventional connection methods, such as snap-fit ​​or welding.

[0068] Furthermore, as a preferred embodiment, see [link to previous document]. Figure 9 and Figure 10 As shown, the armrest body 1 of this embodiment includes a main body and a cantilever 101 connected to the main body. The cantilever 101 is rotatably mounted on the side plate 3a of the mounting bracket 3 via a pivot 2, while the main body supports the elbows of the driver and passengers. Specifically, see... Figure 10As shown, the cantilever 101 in this embodiment includes a first rod 1011 extending radially along the pivot 2, an arc-shaped second rod 1012 located at the free end of the first rod 1011, and a third rod 1013 extending to one side of the second rod 1012. The pivot 2 specifically passes through the first rod 1011, and one end of the pivot 2 has a limiting platform abutting against the first rod 1011, while the other end has a groove and a first retaining spring 12 located within the groove. Furthermore, the first retaining spring 12 abuts against the side plate 3a, thereby restricting the axial movement of the pivot 2 under the action of the first retaining spring 12 and the limiting platform.

[0069] The main body includes a first cover plate 103 and a second cover plate 104 fastened to the front and rear sides of the third rod 1013, and a handrail panel 102 covering the top of the third rod 1013. Furthermore, to improve support, the handrail panel 102 abuts against the third rod 1013 and is screwed together with screws (not shown in the figure). The first cover plate 103 and the second cover plate 104 are respectively snapped together with the handrail panel 102, and the snapping method uses a conventional buckle and snap-hole structure.

[0070] Therefore, in specific implementation, the third rod 1013 of the cantilever 101 can be screwed to the armrest panel 102 first, then the first cover plate 103 is fastened to one side of the third rod 1013 and snapped into the armrest panel 102, and then the second cover plate 104 is fastened to the other side of the third rod 1013 and snapped into the armrest panel 102. Furthermore, to improve user comfort, a foam layer and an outer skin covering the foam layer can be further provided on the armrest panel 102. This structure can be based on a seat structure, or a rubber pad can be directly placed on the top of the armrest panel 102, which also improves user comfort.

[0071] Furthermore, to further improve the usability, a damping part is provided between the handrail body 1 and the mounting bracket 3. The damping part can apply resistance to the rotation of the handrail body 1 and hold the handrail body 1 in any position during rotation. By providing a damping part between the handrail body 1 and the mounting bracket 3 to hold the handrail body 1 in any position during rotation, the stability of the handrail body 1 in the concealed state can be improved. This effectively prevents the handrail body 1 from accidentally rotating out during driving, thus interfering with the driver's driving operation and effectively reducing the driving safety risk caused by the handrail body 1 accidentally rotating out.

[0072] In a preferred embodiment, the damping part includes a pad assembly fitted onto the rotating shaft 2. Specifically, this pad assembly includes a first pad 7 sandwiched between the side plate 3a of the mounting bracket 3 and the cantilever 101, and a second pad 9, a third pad 10, and a fourth pad 11 sequentially sandwiched between the cantilever 101 and the limiting platform of the rotating shaft 2. The first pad 7, the second pad 9, and the fourth pad 11 are all made of nylon to generate greater friction, while the third pad 10 is made of metal to improve the structural strength of the pad assembly. Thus, during the rotation of the handrail body 1, the pads can exert resistance through mutual friction, and when the operating force on the handrail body 1 is removed, the handrail body 1 is held in any position.

[0073] It should be noted that, in addition to using a common hinge structure and the aforementioned damping section, the hinge 2 can also directly use a damping shaft, which would allow the cantilever 101 to be rotatably mounted on the side plate 3a of the mounting bracket 3 via the damping shaft. For example, a damping shaft used in existing laptops or other existing structures can be used.

[0074] Furthermore, as a further embodiment, a limiting part is provided between the mounting frame 3 and the handrail body 1, which can limit the rotation angle of the handrail body 1. By providing a limiting part between the mounting frame 3 and the handrail body 1 to limit the rotation angle of the handrail body 1, it is possible to effectively prevent the handrail body 1 from rotating excessively during use, thereby avoiding safety hazards or operational inconvenience caused by excessive rotation angle.

[0075] In one preferred embodiment, refer to Figure 5 and Figure 8 As shown, the limiting part in this embodiment includes a limiting groove 301 provided on the side plate 3a of the mounting bracket 3, and a limiting post 6 provided on the first rod 1011 of the cantilever 101. The limiting post 6 is inserted into the limiting groove 301 and can slide within the limiting groove 301 as the handrail body 1 rotates. Furthermore, when the limiting post 6 slides to abut against the side walls of the limiting groove 301 at both ends, it can restrict the rotation of the handrail body 1. Moreover, the width of the limiting groove 301 can be adapted to the limiting post 6, thereby guiding the rotation of the handrail body 1 by the abutment of the limiting post 6 against the side walls of the limiting groove 301, thus improving the smoothness of the handrail body 1's rotation. Specifically, the limiting post 6 can be inserted into the cantilever 101 or integrally formed with the cantilever 101.

[0076] It is understandable that the limiting part may include a limiting groove 301 on the side plate 3a and a limiting post 6 on the cantilever 101. Alternatively, the limiting groove 301 may be located on the cantilever 101, and the limiting post 6 on the side plate 3a. Or, in addition to providing a limiting groove 301 on the side plate 3a, the limiting post 6 may abut against both ends of the limiting groove 301 to limit the rotation angle of the handrail body 1. Two opposing limiting plates may also be provided on the side plate 3a, and the rotation angle of the handrail body 1 may be limited by the abutment between the limiting post 6 and the two limiting plates. However, in this case, it is clear that the rotation of the handrail body 1 cannot be guided.

[0077] In this embodiment, as a further implementation, the locking mechanism has multiple locking positions and can lock the armrest body 1 in different usage states. This can meet the support needs of drivers and passengers of different body types. Here, as a preferred embodiment, the locking mechanism includes a pawl 4 rotatably mounted on the armrest body 1, a ratchet portion 304 mounted on the mounting bracket 3, and a first elastic member disposed between the pawl 4 and the armrest body 1. Furthermore, under the action of the first elastic member, the pawl 4 engages with the ratchet portion 304, locking the armrest body 1 in the usage state. It can be understood that the engagement of the pawl 4 with the ratchet portion 304 refers to the teeth of the pawl 4 and the grooves formed by the ratchet portion 304 being conformally arranged and abutting against each other.

[0078] This design provides a stable locking force, firmly locking the handrail body 1 in use. This effectively prevents the handrail body 1 from shaking or shifting due to accidental force during use, improving the safety and comfort of drivers and passengers. Moreover, the simple structure not only facilitates installation and manufacturing but also reduces processing costs and potential failure points caused by complex structures, while also improving the product's durability.

[0079] As a further embodiment, the pawl 4 is provided with a guide portion, and the mounting bracket 3 is provided with a mating portion. Under the action of the first elastic member, the guide portion and the mating portion abut against each other, guiding the pawl 4 to engage with the ratchet portion 304. By providing the guide portion and the mating portion, the rapid engagement of the pawl 4 and the ratchet portion 304 can be effectively ensured, allowing the handrail body 1 to be quickly locked in the use state. Moreover, the preload of the first elastic member keeps the guide portion pressed against the mating portion, further enhancing the engagement stability and effectively preventing the pawl 4 from accidentally disengaging due to vehicle vibration or external interference, thereby improving the stability of the handrail body 1 in use.

[0080] Specifically, the structure of the pawl 4 in this embodiment is shown below. Figure 11 and Figure 12As shown, it includes a rod body portion and a claw portion located at one end of the rod body portion. A shaft hole is provided at one end of the rod body portion, and three teeth are spaced apart on the claw portion. Simultaneously, a clearance groove 401 is provided at the location of the shaft hole in the rod body portion, allowing the pawl 4 to be rotatably mounted on the first rod body 1011 of the cantilever 101 via a shaft 8 located within the shaft hole. Furthermore, in a preferred embodiment, the first elastic element is specifically a torsion spring 5 sleeved on the shaft 8, located within the clearance groove 401, with its two ends inserted into the first rod body 1011 and the rod body portion. Additionally, under the elastic action of the torsion spring 5, the pawl 4 has a tendency to rotate instantaneously, thus pressing the pawl 4 against the ratchet portion 304, thereby locking the handrail body 1 in the use state.

[0081] In addition, as a specific embodiment, such as Figure 6 As shown, one side of the shaft 8 has a flange that protrudes radially outward, abutting against the first rod 1011. Simultaneously, the other end of the shaft 8 has a circumferentially oriented groove, within which a second retaining spring abuts against the pawl 4. Therefore, the flange and the second retaining spring restrict axial movement of the shaft 8, preventing it from disengaging from the first rod 1011 and the pawl 4. It should be noted that the arrangement of the pawl 4 and the first rod 1011 is not limited to the above structure; any arrangement that allows relative rotation between the pawl 4 and the first rod 1011 is acceptable.

[0082] Correspondingly, such as Figure 8 As shown, a locking block protruding towards the base plate 3b is provided on the side plate 3a of the mounting bracket 3. The ratchet portion 304 is provided on the locking block, and specifically, the ratchet portion 304 includes a plurality of ratchet teeth arranged sequentially along the rotation direction of the armrest body 1. In one specific embodiment, seven ratchet teeth are arranged sequentially and can engage with the teeth of the pawl 4 in five locking positions, thereby locking the armrest body 1 in five different usage states, that is, five different support heights, which can meet the requirements of drivers and passengers of different body types.

[0083] It is understandable that the number of teeth on the pawl 4 and the number of teeth on the ratchet part 304 are not limited to those shown in the figure. They can be adjusted according to design requirements to change the number of locking positions.

[0084] Furthermore, in a preferred embodiment, the guide portion of this embodiment includes a guide post 13 inserted into the pawl 4, and a second elastic member abutting between the guide post 13 and the pawl 4. Under the action of the second elastic member, the guide post 13 abuts against the mounting bracket 3. Therefore, when the guide post 13 enters the guide groove 302 via the guide surface 305, it can be inserted into the guide groove 302 under the action of the second elastic member, and can have good abutment stability with the groove wall of the guide groove 302, thereby improving the guiding effect of the guide groove 302 on the guide post 13.

[0085] Specifically, such as Figure 13 As shown, the guide post 13 has a receiving hole extending axially to one end, and the second elastic element is specifically a spring 14 disposed in the receiving hole. During assembly, the spring 14 can be placed in the receiving hole, and then the guide post 13 can be inserted into the fixing hole of the rod portion of the pawl 4. At this time, under the action of the spring 14, the guide post 13 can abut against the side plate 3a of the mounting bracket 3, thereby preventing the guide post 13 from disengaging from the pawl 4 and allowing the guide post 13 to rotate relative to the pawl 4. This reduces the friction between the guide post 13 and the mating part, improving the smoothness of the pawl 4's movement.

[0086] And reference Figure 8 and Figure 14 As shown in the diagram, in a preferred embodiment, the mating part includes a mating block 303 disposed above the ratchet portion 304. The mating block 303 has a first mating surface 3031 and a second mating surface 3032 located on one side of the first mating surface 3031. Furthermore, as the armrest body 1 is rotated out, the first mating surface 3031 and the second mating surface 3032 sequentially abut against the guide portion, guiding the pawl 4 to engage with the ratchet portion 304.

[0087] The mating part of this embodiment includes a mating block 303 with a first mating surface 3031 and a second mating surface 3032. Its structure is simple and easy to design and implement. Furthermore, the first mating surface 3031 and the second mating surface 3032 can sequentially abut against the guide part during the rotation of the handrail body 1, making the movement of the pawl 4 smoother during engagement with the ratchet portion 304. This helps ensure the normal operation and reliable locking of the locking mechanism, effectively preventing the pawl 4 from jamming or getting stuck during movement. This makes the transition from the handrail body 1 to the usage state smoother, improving the user experience.

[0088] Furthermore, the mating mechanism makes the engagement process between the pawl 4 and the ratchet tooth 304 more stable, effectively reducing the impact and shaking that may occur at the moment of engagement, thus improving the structural stability of the locking mechanism itself. It also extends the service life of the pawl 4 and enhances the stability of the entire handrail structure during use, providing safer and more reliable support.

[0089] Specifically, such as Figure 8 As shown, the mating block 303 is formed by a mating protrusion 306 provided on the side plate 3a. The first mating surface 3031 is generally horizontal, while the second mating surface 3032 includes a first portion arranged at an obtuse angle to the first mating surface 3031 and a second portion arranged generally perpendicular to the first mating surface 3031. Thus, the pawl 4 can be guided to engage with the ratchet portion 304 by the abutment of the guide post 13 with the first mating surface 3031 and the second mating surface 3032.

[0090] In addition, as a further embodiment, the mounting bracket 3 is provided with a guide groove 302 located above the ratchet portion 304, and a guide surface 305 located between the guide groove 302 and the ratchet portion 304. Furthermore, the guide surface 305 abuts against the guide portion, guiding the guide portion into the guide groove 302 and disengaging the pawl 4 from the ratchet portion 304. Here, through the sliding engagement between the guide surface 305 and the guide portion, i.e., the guide post 13, the driver or passenger only needs to apply a small external force (such as pulling the armrest body 1 upwards) to disengage the pawl 4 from the ratchet portion 304, thus unlocking the vehicle without any further operation, simplifying the process. Moreover, since the guide groove 302 and the guide surface 305 are integrated into the mounting bracket 3, no additional unlocking mechanism is required, resulting in a compact structure suitable for confined spaces within a vehicle.

[0091] Here, as a preferred embodiment, such as Figure 8 As shown, the guide groove 302 is an arc-shaped groove centered on the rotation center of the armrest body 1, with the top of the arc-shaped groove extending above the mating block 303. Furthermore, as the armrest body 1 is screwed in, the guide portion can disengage from the top of the guide groove 302 and abut against the mating portion. The guide groove 302 is formed by the inward indentation of the side plate 3a. Therefore, by providing the aforementioned spring 14 between the guide post 13 and the pawl 4, when the guide post 13 slides into the guide groove 302 from the guide surface 305, the spring 14 can release energy to extend the guide post 13 and insert it into the guide groove 302, thereby ensuring contact between the guide post 13 and the groove wall of the guide groove 302.

[0092] By designing the guide groove 302 as an arc-shaped groove centered on the rotation center of the handrail body 1, it can match the rotational movement of the handrail body 1, which helps to ensure the relative motion coordination between the components and effectively avoids interference or jamming, making the operation of the handrail structure smoother. Extending the top of the arc-shaped groove to above the mating block 303 allows the guide part to disengage from the top of the arc-shaped groove and smoothly abut against the mating part when the handrail body 1 is screwed in, effectively ensuring the smoothness of the screwing in and out movements of the handrail body 1, improving the convenience and stability of operation, and enhancing the user experience.

[0093] Based on the above overall description, during the installation of the handrail structure in this embodiment, the limiting post 6 is first installed on the cantilever 101, and then the guide post 13 and spring 14 are installed on the pawl 4 to assemble a pawl assembly. Next, the pawl assembly 4 and torsion spring 5 are installed in the shaft hole of the cantilever 101 via the shaft body 8 to assemble the cantilever assembly. Then, the cantilever assembly and gasket assembly are installed on the mounting bracket 3, so that the pawl 4 and ratchet portion 304 on the cantilever assembly engage, allowing the limiting post 6 on the cantilever assembly to insert into the limiting groove 301, thus assembling the handrail support assembly. Finally, the handrail panel 102 is screwed onto the cantilever 101 of the handrail support assembly, the first cover plate 103 is snapped onto the handrail panel 102, and then the second cover plate 103 is snapped onto the handrail panel 102, thus completing the assembly of the handrail structure.

[0094] When the armrest structure is installed on the sub-dashboard, first screw the armrest structure onto the armrest box 17 to form the armrest box assembly. Then, screw the storage box 21 onto the sub-dashboard body 15 and the armrest box assembly. Next, use clips to install the upper cover 19 onto the sub-dashboard body 15 and the storage box 21. Then, use clips and screws to install the left cover 16 onto the assembly consisting of the sub-dashboard body 15, the storage box 21, and the upper cover 19. Then, use clips to install the right cover 20 onto the assembly. Finally, use clips to install the rear cover 18 onto the sub-dashboard body 15 and the armrest box 17, thus completing the installation of the armrest structure on the sub-dashboard.

[0095] In this embodiment, the armrest structure, when in use, rotates the armrest panel 102 of the armrest body 1 by pulling it upwards, stopping when it reaches a comfortable position for the driver. At this point, pressing down on the armrest panel 102 locks its position. To adjust the position of the armrest panel 102 downwards, first, pull the armrest panel 102 to rotate it to its highest position. After reaching this position, pressing down on the armrest panel 102 rotates it back to its lowest position. Then, the armrest panel 102 can be adjusted upwards to the driver's desired comfortable position; at this point, pressing down on the armrest panel 102 locks the armrest body 1.

[0096] Specifically, firstly, the armrest panel 102 is in the hidden state at position P1-2. At this time, the guide post 13 is located at position P1-1 on the first mating surface 3031, and the limiting post 6 is located at the top position P1-3 of the limiting groove 301. At this time, if the armrest panel 102 is pressed inward, since the limiting post 6 is located at the extreme position at the top of P1-3, it cannot continue to move, so the armrest panel 102 does not move.

[0097] Pulling the armrest panel 102 outwards rotates the armrest panel 102 and cantilever 101 to a 20° position, the armrest panel 102 is at position P2-2. The cantilever 101 drives the guide post 13 on the pawl 4 to move to the right along the first mating surface 3031 to position P2-1. Due to the action of the torsion spring 5, the guide post 13 on the pawl 4 will press against the first mating surface 3031 at this time. At the same time, the limiting post 6 is located at position P2-3 in the limiting groove 301.

[0098] Continue pulling the armrest panel 102 outwards until it rotates to a 50° position along with the cantilever 101. At this point, the armrest panel 102 is at position P3-2. The cantilever 101 then moves the guide post 13 on the pawl 4 to the left along the first mating surface 3031 to position P3-1. Due to the force of the torsion spring 5, the guide post 13 on the pawl 4 presses against the first mating surface 3031, and the limiting post 6 is located at position P3-3 in the limiting groove 301.

[0099] Continue pulling the armrest panel 102 outwards until it rotates to a 70° position along with the cantilever 101. At this position, the armrest panel 102 is at position P4-2. The cantilever 101 drives the guide post 13 on the pawl 4 to slide along the second mating surface 3032 to the left of the first mating surface 3031 to position P4-1, causing the pawl 4 and the ratchet portion 304 to engage. Due to the elastic force of the torsion spring 5, the pawl 4 will press against the ratchet portion 304. When the driver presses down on the armrest panel 102, the ratchet portion 304 will support the pawl 4, preventing it from rotating. At this point, the armrest panel 102 is locked, and the limiting post 6 is located at position P4-3 in the limiting groove 301.

[0100] Pulling the armrest panel 102 outwards rotates it and the cantilever 101 to a 90° position, placing the armrest panel 102 at position P5-2. The cantilever 101 then moves the guide post 13 on the pawl 4 to position P5-1, engaging the pawl 4 with the ratchet tooth 304. Due to the force of the torsion spring 5, the pawl 4 presses against the ratchet tooth 304. When the driver presses down on the armrest panel 102, the ratchet tooth 304 supports the pawl 4, preventing it from rotating. At this point, the armrest panel 102 is locked, representing its highest usable position. The limiting post 6 is located at position P5-3 in the limiting groove 301.

[0101] Continue pulling the armrest panel 102 upwards until it rotates to a 120° position along with the cantilever 101. At this point, the armrest panel 102 is at position P6-2. The cantilever 101 causes the guide post 13 on the pawl 4 to slide up along the guide surface 305 into the guide groove 302 at position P6-1, disengaging the pawl 4 from the ratchet tooth 304. Due to the force of the torsion spring 5, the guide post 13 on the pawl 4 presses against the arc-shaped limiting surface. At this point, when the driver continues to rotate the armrest panel 102 upwards, the limiting post 6 is located at the lower left limit position of P6-3 in the limiting groove 301. Therefore, the armrest panel 102 cannot continue to rotate upwards, and it reaches its highest rotatable point.

[0102] After the armrest panel 102 reaches its highest point, it can rotate downwards. When the armrest panel 102, along with the cantilever 101, rotates to a position of 60°, the armrest panel 102 is at position P7-2. The cantilever 101 drives the guide post 13 on the pawl 4 to slide along the arc-shaped limiting groove 301 to position P7-1. Due to the elastic force of the torsion spring 5, the guide post 13 on the pawl 4 will press against the groove wall of the arc-shaped limiting groove 301, and the limiting post 6 will be located at position P7-3 in the limiting groove 301.

[0103] Continue rotating the armrest panel 102 downwards. When the armrest panel 102, along with the cantilever 101, reaches the 0° position, it is at position P1-2. The cantilever 101 drives the guide post 13 on the pawl 4 to slide down along the arc-shaped limiting groove 301 to position P1-1 on the first mating surface 3031. Due to the elastic force of the torsion spring 5, the guide post 13 on the pawl 4 presses against the first mating surface 3031, and the limiting post 6 is located at position P1-3 in the limiting groove 301. The armrest panel 102 returns to its hidden state. To adjust the position of the armrest panel 102 upwards, repeat the above operation.

[0104] In addition to manually rotating the handrail body 1 as described above, the handrail body 1 can also be driven to rotate by a motor or other driving mechanism. In this case, the motor can be mounted on the side plate 3a, and the motor shaft can be connected to the rotating shaft 2 of the handrail body 1, and the rotating shaft 2 can be fixedly connected to the handrail body 1. Thus, the motor can drive the handrail body 1 to rotate via the rotating shaft 2.

[0105] Therefore, the armrest structure of this embodiment, by adopting the above structure, not only supports the elbows of the driver and passengers, but also has multiple support heights to meet the requirements of people of different body types. Moreover, it is convenient to operate, simple in structure, and easy to design and implement. In addition, because the armrest body 1 can rotate out to one side of the sub-dashboard and is located on one side of the sub-dashboard, it is closer to the driver and passengers than armrests in other existing technologies, thus providing better support and better solving the problem of driver and passenger fatigue.

[0106] In addition, this embodiment also relates to a vehicle having the above-described handrail structure.

[0107] In this embodiment, the vehicle features the aforementioned armrest structure, which not only conceals the armrest body 1 when not in use, preventing interference with the driver and passengers, but also allows the armrest body 1 to be rotated out from one side of the instrument panel when in use, supporting the elbow and effectively preventing fatigue caused by elbow drooping, thus improving driving comfort.

[0108] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
