Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a rotating car armrest with a seat belt limiting structure. Background Technology

[0002] In automotive interior design, armrests are important components that enhance driving comfort and convenience, providing elbow support for drivers and passengers and allowing them to place their arms to relieve fatigue during travel. With the increasing demands for space utilization and ease of use in automotive interior design, new rotating armrests have emerged. Rotating armrests aim to solve the problems of traditional fixed armrests, which occupy a lot of space and easily obstruct passage when passengers get in and out of the car or adjust their seating position, thereby further optimizing the utilization efficiency of the car's interior space.

[0003] In related technologies, the rotating car armrests currently in the field are mainly composed of two core components: the housing and the armrest rod. The armrest rod and the housing are assembled by a rotating connection, and the armrest can be folded or unfolded by rotating to adapt to different usage scenarios. The housing is usually fixedly installed on the side of the car seat to ensure the overall installation stability of the armrest.

[0004] Meanwhile, to accommodate the use of car seat belts, the corresponding seat belt structure includes a buckle and webbing. Inside the housing, there is also a buckle slot. In actual use, the driver and passengers can pull the webbing to push the buckle into the housing, so that the buckle inlet and the buckle slot inside the housing can be inserted and engaged, thereby realizing the installation and fixation of the seat belt.

[0005] However, after the buckle and slot are fully engaged, the buckle is prone to displacement and wobbling, which can lead to poor overall stability of the seat belt. The wobbling of the buckle may cause the engagement between the buckle and the slot to loosen, affecting the driver's and passengers' confidence in the reliability of the seat belt assembly. Utility Model Content

[0006] To address the aforementioned issues, this application provides a rotating car handrail with a seatbelt limiting structure.

[0007] This application provides a rotating car handrail with a seatbelt limiting structure, which adopts the following technical solution: it includes a housing, a limiting member is provided inside the housing, the limiting member is fixed inside the housing, the limiting member is provided with a limiting groove, the snap fastener is provided with a limiting shell, the snap fastener is fixed to one end of the limiting shell, the end of the limiting shell away from the snap fastener is connected to a webbing, and the limiting shell is built into the limiting groove.

[0008] By adopting the above technical solution, during vehicle operation, the driver's body movements cause the webbing associated with them to swing. Since the limiting shell is fixedly connected to the webbing via the snap fastener, the swing of the webbing synchronously causes the limiting shell to swing as well. When the limiting shell swings, because the limiting shell is built into the limiting groove, the side wall of the limiting shell abuts against the side wall of the limiting groove, thereby constraining the swing of the limiting shell through the limiting groove. This effectively limits the displacement space of the limiting shell inside the shell, thereby causing the snap fastener fixed to it to maintain a stable state synchronously. This reduces the swing amplitude and frequency of the snap fastener caused by vibration and other factors during vehicle operation, improves the overall stability of the snap fastener assembly, and reduces the problem of the snap fastener loosening due to shaking. When using the seat belt, the driver and passengers can intuitively perceive the stability of the snap fastener assembly, thereby increasing their confidence in the reliability of the seat belt assembly.

[0009] This limiting shell can simultaneously position the snap-fit ​​buckle. Since the snap-fit ​​buckle is fixedly connected to the limiting shell, the snap-fit ​​buckle is positioned accordingly after the position of the limiting shell is stably constrained, always remaining within the preset snap-fit ​​path range. In this way, when performing snap-fit ​​operations later, the snap-fit ​​buckle is already in the position corresponding to the snap-fit ​​position, improving the convenience of snap-fit ​​operations.

[0010] Preferably, the outer wall of the housing is provided with a first through-hole for the limiting shell to pass into the interior of the housing, and the first through-hole communicates with the limiting groove.

[0011] By adopting the above technical solution, the first inlet provides a channel for the limiting shell and the snap fastener fixedly connected to the limiting shell to enter the interior of the shell. The first inlet is connected to the limiting groove, so that the limiting shell and the snap fastener can be directly aligned with the limiting groove after being inserted, thereby allowing the outer wall of the limiting shell to smoothly abut against the inner wall of the limiting groove.

[0012] Preferably, the outer side wall of the limiting shell away from the snap fastener abuts against the side wall of the first through-hole.

[0013] By adopting the above technical solution, the first through-hole serves as the channel for the limiting shell and the snap fastener to enter the interior of the housing. The abutment between the side wall of the first through-hole and the outer side wall of the limiting shell away from the snap fastener can restrict the displacement of the limiting shell from the entrance end. At the same time, combined with the limiting groove's limiting effect on the limiting shell, the first through-hole and the limiting groove together constrain both ends of the limiting shell, thereby ensuring that the snap fastener fixed thereto remains stable. This further reduces the overall swing space and amplitude of the limiting shell and improves the overall stability of the snap fastener after assembly.

[0014] Preferably, the width of the first through-hole and the limiting groove is greater than the width of the limiting shell.

[0015] By adopting the above technical solution, the width of the first insertion port and the limiting groove is set to be greater than the width of the limiting shell. That is, the limiting shell is radially constrained by the side wall of the first insertion port and the inner side wall of the limiting groove, which limits the large displacement of the limiting shell and ensures the basic stability of the buckle. At the same time, the space reserved by the width difference allows the limiting shell to swing slightly. This slight swing can provide a certain degree of assembly tolerance when the limiting shell and the buckle are inserted into the shell, reducing the problem of insertion jamming due to perfect size fit. It can also buffer the impact of vibration when the driver inserts or removes the buckle of the seat belt or when the vehicle vibrates slightly. It will not cause stiffness and restraint to the driver's operation due to the structure being completely fixed. While ensuring the overall stability of the buckle, it improves the comfort of the driver during use.

[0016] Preferably, the edges of the first through-hole and the limiting groove are both rounded.

[0017] By adopting the above technical solution, during the process of the limiting shell and the snap fastener passing through the first through-hole and entering the limiting groove, the rounded corners allow the limiting shell to enter the limiting groove more smoothly and form an abutment fit with the groove wall, improving the convenience of assembly operations.

[0018] Preferably, it further includes an installation component, which is fixed to the side of the limiting member away from the housing, and the snap-fit ​​buckle is disposed on the side of the limiting member away from the housing, and the snap-fit ​​buckle engages with the installation component.

[0019] By adopting the above technical solution, the contact between the limiting shell and the limiting groove can continuously exert radial constraint on the limiting shell, ensuring the basic stability after the snap-fit ​​buckle is assembled. The snap-fit ​​buckle and the mounting part are respectively set on the side of the limiting shell away from the shell and the side of the limiting part away from the shell, so that the contact position between the limiting shell and the limiting groove corresponds to the side of the limiting shell closer to the shell. The snap-fit ​​buckle and the limiting part are reasonably offset in space. The contact structure between the limiting shell and the limiting groove will not block the snap-fit ​​path of the snap-fit ​​buckle and the mounting part, realizing that the contact positioning of the limiting shell and the snap-fit ​​fixing of the snap-fit ​​buckle and the mounting part do not hinder each other.

[0020] Preferably, the mounting component is provided with a second through-hole and a snap-fit ​​inlet, the second through-hole and the snap-fit ​​inlet are connected, the width of the second through-hole is greater than the width of the snap-fit ​​buckle, and the width of the snap-fit ​​inlet is less than the width of the snap-fit ​​buckle.

[0021] By adopting the above technical solution, since the width of the second through-hole is greater than that of the snap fastener, the snap fastener can directly pass through the second through-hole when entering the installation part. The second through-hole is connected to the snap fastener entrance. After the snap fastener passes smoothly through the second through-hole, it can further enter the snap fastener entrance. The width of the snap fastener entrance is smaller than that of the snap fastener, so that the snap fastener and the snap fastener entrance can be snapped together, thereby achieving the snap fastening and fixing of the snap fastener.

[0022] Preferably, the end of the snap fastener away from the limiting shell is provided with a first snap fastening part, and the side of the snap fastening inlet away from the second through-hole is provided with a second snap fastening part. The edge of the snap fastening inlet can undergo elastic deformation, and the sidewall of the first snap fastening part abuts against the sidewall of the second snap fastening part.

[0023] By adopting the above technical solution, the snap fastener is pushed towards the snap fastening inlet. Because the edge of the snap fastening inlet has elastic deformation capability, even if the width of the snap fastening inlet is smaller than the snap fastener, the edge of the snap fastening inlet will undergo adaptive deformation under the pushing force, ensuring that the first snap fastening part can smoothly pass into the snap fastening inlet. After the first snap fastening part has completely passed through the snap fastening inlet, the elastic deformation of the edge of the snap fastening inlet is restored. At this time, the side wall of the first snap fastening part and the side wall of the second snap fastening part are tightly abutted. With the abutting cooperation between the side wall of the first snap fastening part and the second snap fastening part, as well as the dimensional constraint of the snap fastening inlet width on the snap fastener, the snap fastener is restricted within the snap fastening inlet.

[0024] Preferably, the edges of the first snap-fit ​​portion and the snap-fit ​​inlet are both rounded.

[0025] By adopting the above technical solution, during assembly, the first snap-fit ​​part needs to push the edge of the snap-fit ​​entrance to undergo elastic deformation in order to pass through the snap-fit ​​entrance. The rounded corners allow the first snap-fit ​​part to pass through the snap-fit ​​entrance more smoothly, while reducing wear caused by long-term contact.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A snap-fit ​​fastener is fixed to one end of the limiting shell. The end of the limiting shell away from the snap-fit ​​fastener is connected to the webbing, and the limiting shell is built into a limiting groove. When the car is moving, the driver's body movements will cause the webbing to swing. Because the limiting shell is fixedly connected to the webbing via the snap-fit ​​fastener, the swing of the webbing will synchronously cause the limiting shell to swing. Since the limiting shell is built into the limiting groove, the side wall of the limiting shell abuts against the side wall of the limiting groove during swinging. The limiting groove thus constrains the swinging of the limiting shell, effectively limiting the displacement space of the limiting shell within the shell, thereby... The moving buckle remains stable, reducing the amplitude and frequency of its swing caused by vehicle vibrations, minimizing loosening issues, and allowing passengers to intuitively perceive the buckle's stability when using the seatbelt, thus increasing their confidence in the seatbelt's assembly reliability. Simultaneously, the limiting shell's positioning also synchronously positions the buckle. Because the buckle is fixed to the limiting shell, once the limiting shell's position is stable, the buckle's engagement position remains within the preset engagement path range, eliminating the need for additional alignment during subsequent engagement operations and improving engagement convenience.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a rotating car armrest with a seatbelt limiting structure. (See also...) Figure 1 and Figure 2The action is applied to the snap fastener 1, which includes a housing 3, a limiting member 4, and a limiting shell 2. The housing 3 is fixed next to the seat in the vehicle, the limiting member 4 is fixed inside the housing 3, and the limiting member 4 is provided with a limiting groove 41. The snap fastener 1 is provided with a limiting shell 2. The snap fastener 1 is fixed to one end of the limiting shell 2, and the end of the limiting shell 2 away from the snap fastener 1 is connected to the webbing. When the webbing swings, the inner side wall of the limiting groove 41 abuts against the outer side wall of the limiting shell 2.

[0036] This explains that during vehicle operation, the driver's body movements cause the webbing associated with them to swing. Since the limiting shell 2 is fixedly connected to the webbing via the snap fastener 1, the swinging of the webbing synchronously causes the limiting shell 2 to swing as well. When the limiting shell 2 swings, its side wall abuts against the side wall of the limiting groove 41, thus constraining the swing of the limiting shell 2. This effectively limits the displacement space of the limiting shell 2 within the shell 3, thereby causing the snap fastener 1, which is fixed to it, to maintain a stable state. This reduces the swing amplitude and frequency of the snap fastener 1 caused by vibration and other factors during vehicle operation, improving the overall stability of the snap fastener 1 after assembly and reducing the problem of the snap fastener 1 becoming loose due to shaking. When using the seat belt, passengers can intuitively perceive the stability of the snap fastener 1 assembly, thereby increasing their confidence in the reliability of the seat belt assembly.

[0037] Furthermore, this limiting of the limiting shell 2 can simultaneously position the snap-fit ​​position of the snap-fit ​​buckle 1. Since the snap-fit ​​buckle 1 is fixedly connected to the limiting shell 2, after the position of the limiting shell 2 is stably constrained, the snap-fit ​​position of the snap-fit ​​buckle 1 is also positioned accordingly, always remaining within the preset snap-fit ​​path range. In this way, when performing snap-fit ​​operations later, the snap-fit ​​buckle 1 is already in the position corresponding to the snap-fit ​​position, improving the convenience of the snap-fit ​​operation.

[0038] Reference Figure 3 and Figure 4 Specifically, the limiting member 4 is fixed to the side wall of the housing 3 by bolts. The limiting housing 2 is a rectangular structure with a smooth transition. The shape of the limiting groove 41 is adapted to the outer side wall of the limiting housing 2. One end of the limiting housing 2 is fixedly connected to the snap fastener 1. The left and right ends of the limiting housing 2 and the side wall near the snap inlet 52 abut against the side wall of the limiting groove 41. The limiting housing 2 is made of plastic.

[0039] Furthermore, the housing 3 includes a first through-hole 31, the shape of which matches the shape of the limiting housing 2. The first through-hole 31 is connected to the limiting groove 41. The width of the first through-hole 31 and the limiting groove 41 is slightly larger than the width of the limiting housing 2. Furthermore, when the limiting housing 2 swings, the side wall of the limiting housing 2 away from the snap fastener 1 will abut against the side wall of the first through-hole 31 on the outer side wall of the housing 3, thereby constraining the swing of the limiting housing 2 through the first through-hole 31.

[0040] This explains that the first inlet 31 provides a channel for the limiting shell 2 and the snap fastener 1 fixedly connected to the limiting shell 2 to enter the interior of the shell 3. The first inlet 31 is connected to the limiting groove 41, so that the limiting shell 2 and the snap fastener 1 can be directly aligned with the limiting groove 41 after being inserted. The abutment between the side wall of the first inlet 31 and the outer side wall of the limiting shell 2 away from the snap fastener 1 can restrict the displacement of the limiting shell 2 from the inlet end of the limiting shell 2. At the same time, combined with the limiting effect of the limiting groove 41 on the limiting shell 2, the first inlet 31 and the limiting groove 41 together form a constraint on both ends of the limiting shell 2, thereby driving the snap fastener 1 fixed thereto to always maintain a stable state, further reducing the overall swing space and amplitude of the limiting shell 2 and improving the overall stability of the snap fastener 1 after assembly.

[0041] Meanwhile, since the width of the first inlet 31 and the limiting groove 41 is slightly larger than the width of the limiting shell 2, the limiting shell 2 is radially constrained by the side wall of the first inlet 31 and the inner side wall of the limiting groove 41, limiting the large displacement of the limiting shell 2 and ensuring the basic stability of the buckle 1. At the same time, the space reserved by the width difference allows the limiting shell 2 to swing slightly. This slight swing can provide a certain degree of assembly tolerance when the limiting shell 2 and the buckle 1 are inserted into the shell 3, reducing the problem of insertion jamming due to the perfect fit of the size. It can also buffer the impact of vibration when the driver inserts or removes the buckle 1 of the seat belt or when the vehicle vibrates slightly, so as not to cause stiff restraint to the driver's operation due to the complete fixation of the structure. While ensuring the overall stability of the buckle 1, it improves the comfort of the driver during use.

[0042] Furthermore, the limiting shell 2, the first through-hole 31, and the limiting groove 41 are all rounded. The limiting shell 2 needs to pass through the first through-hole 31 and enter the limiting groove 41. The rounded corners of the limiting shell 2, the first through-hole 31, and the limiting groove 41 can replace sharp edges, allowing the limiting shell 2 to pass smoothly and form contact with the first through-hole 31 and the limiting groove 41, effectively reducing assembly jamming and improving operational convenience. During vehicle operation, the limiting shell 2 may experience slight displacement due to the swing of the webbing. At this time, the rounded corner contact reduces local wear on the limiting shell 2, the first through-hole 31, and the limiting groove 41.

[0043] Reference Figure 5 and Figure 6Furthermore, it also includes a mounting component 5, which is fixed to the end of the limiting component 4 away from the side wall of the housing 3. A snap-fit ​​buckle 1 is located on the side of the limiting housing 2 away from the housing 3, and the snap-fit ​​buckle 1 engages with the mounting component 5. Specifically, the mounting component 5 is provided with a second through-hole 51 and a snap-fit ​​inlet 52. The second through-hole 51 is located at the end of the mounting component 5 near the first through-hole 31, and the snap-fit ​​inlet 52 is located at the end of the mounting component 5 away from the first through-hole 31. The snap-fit ​​inlet 52 corresponds to the first through-hole 31. Furthermore, a second engaging portion 521 is provided at the end of the engaging inlet 52 away from the second through inlet 51, and a second engaging portion 521 is provided at both ends of the engaging inlet 52. The engaging buckle 1 is provided with a first engaging portion 11, and the first engaging portion 11 engages with the second engaging portion 521. In this embodiment, a first engaging portion 11 is provided on both sides of the end of the engaging buckle 1 away from the limiting shell 2, and the first engaging portion 11 is a protrusion.

[0044] Furthermore, the width of the second through-hole 51 is greater than the overall width of the snap fastener 1, the width of the snap fastener 52 is less than the overall width of the snap fastener 1, and the length of the second snap fastening portion 521 at both ends of the snap fastener 52 is relatively matched with the length of the first snap fastening portion 11 at both ends of the snap fastener 1, and the two ends of the snap fastener 52 can undergo elastic deformation.

[0045] This explains that, since the mounting component 5 is fixed to the end of the limiting component 4 away from the side wall of the housing 3, and the second through-hole 51 is located at the end close to the first through-hole 31, and the width of the second through-hole 51 is greater than the overall width of the snap fastener 1, the snap fastener 1 can easily pass through the mounting component 5 from the second through-hole 51. At the same time, the snap fastener 52 is located at the end of the mounting component 5 away from the first through-hole 31 and corresponds to the first through-hole 31, which can guide the snap fastener 1 to accurately connect along the predetermined path.

[0046] Meanwhile, since the snap-fit ​​positions of the snap-fit ​​buckle 1 and the mounting part 5 are respectively set on the side of the limiting shell 2 away from the shell 3 and the side of the limiting part 4 away from the shell 3, the abutment position of the limiting shell 2 and the limiting groove 41 is respectively on the side of the limiting shell 2 close to the shell 3. The snap-fit ​​buckle 1 and the limiting part 4 are reasonably staggered in space. The abutment structure of the limiting shell 2 and the limiting groove 41 will not block the snap-fit ​​path of the snap-fit ​​buckle 1 and the mounting part 5, so that the abutment positioning of the limiting shell 2 and the snap-fit ​​fixing of the snap-fit ​​buckle 1 and the mounting part 5 do not hinder each other.

[0047] Furthermore, during assembly, the elastic deformation at both ends of the snap-fit ​​inlet 52 can adaptively expand under the push of the snap-fit ​​buckle 1, providing a passage space for the wider snap-fit ​​buckle 1 and the first snap-fit ​​part 11. When the first snap-fit ​​part 11 is fully inserted into the snap-fit ​​inlet 52, the elastic deformation is restored, and the sidewalls of the second snap-fit ​​parts 521 at both ends of the snap-fit ​​inlet 52 abut against the sidewalls of the first snap-fit ​​parts 11 on both sides of the snap-fit ​​buckle 1, realizing the snap-fit ​​engagement of the first snap-fit ​​part 11 and the second snap-fit ​​part 521.

[0048] In addition, the edges of the snap-fit ​​inlet 52 and the first snap-fit ​​part 11 are both rounded. During assembly, the first snap-fit ​​part 11 needs to push the edge of the snap-fit ​​inlet 52 to undergo elastic deformation in order to pass through the snap-fit ​​inlet 52. The rounded corners allow the first snap-fit ​​part 11 to pass through the snap-fit ​​inlet 52 more smoothly, while also reducing wear caused by long-term contact.

[0049] In addition, the embodiments of this application also include a handrail 6, which is rotatably connected to the mounting component 5. This is prior art and will not be described in detail here.

[0050] The implementation principle of a rotating car handrail with a seat belt limiting structure in this application embodiment is as follows: First, the housing 3 is fixed next to the seat in the car. The limiting member 4 with the limiting groove 41 is fixed inside the housing 3 by bolts. The shape of the limiting groove 41 is adapted to the outer wall of the limiting housing 2. At the same time, one end of the buckle 1 is fixed to the limiting housing 2, and the other end of the limiting housing 2 is connected to the webbing. The mounting member 5 is fixed to the end of the limiting member 4 away from the housing 3.

[0051] When the driver operates, he then holds the limiting shell 2 connected to the webbing and inserts the limiting shell 2, along with the snap fastener 1, through the first through-hole 31 on the outside of the housing 3. Since the first through-hole 31 is connected to the limiting groove 41 on the limiting member 4 and its width is slightly larger than that of the limiting shell 2, the limiting shell 2 can smoothly enter the housing 3 and form an abutment with the inner side wall of the limiting groove 41. Then, he continues to push the snap fastener 1 so that the snap fastener 1 passes through the second through-hole 51 on the mounting member 5 near the first through-hole 31. Then, he pushes the snap fastener 1 to move towards the snap fastener 52 of the mounting member 5. The two ends of the snap fastener 52 expand elastically under the action of the thrust until the first snap fastener 11 on both sides of the snap fastener 1 is completely inserted into the snap fastener 52. At this time, the snap fastener 52 recovers its elastic deformation, and the second snap fastener 521 at both ends of the snap fastener 52 abuts and locks against the side wall of the first snap fastener 11.

[0052] During vehicle operation, the driver's body movements cause the webbing associated with them to swing. Since the limiting shell 2 is fixedly connected to the webbing via the snap fastener 1, the swinging of the webbing synchronously causes the limiting shell 2 to swing as well. When the limiting shell 2 swings, the side wall of the limiting shell 2 away from the snap fastener 1 abuts against the side wall of the first through-hole 31 on the outer wall of the shell 3, thereby constraining the swinging of the limiting shell 2 through the first through-hole 31. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
