Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, in particular to a new driver enclosure structure. Background Art

[0002] In modern transportation, ensuring the safety and concentration of drivers is of utmost importance, especially in public transportation such as buses and tour buses. To this end, a common safety measure is to install a so-called "driver enclosure" around the driver's seat, which is a physical barrier designed to protect the driver from passenger interference and thus ensure driving safety. The driver enclosure usually comes with an opening door for the driver to enter and exit the driving area conveniently.

[0003] Under the framework of the prior art, the driver enclosure system is usually designed to consist of two key components: the rear enclosure component and the front guardrail component. The rear enclosure component adopts an L-shaped structure and is firmly installed at the rear of the driver's seat of the vehicle body. Its design purpose is to form a solid protective barrier to isolate the driver from the passenger area and ensure the safety and concentration of the driver during operation. The front guardrail component is more complex. It not only includes a guard door hinged to one side of the rear enclosure component but also is equipped with a locking structure fixed to the side of the instrument panel inside the vehicle body. One end of the guard door is connected to the rear enclosure component by a hinge, allowing the opening and closing of the door, while the other end forms a detachable connection with the locking structure, ensuring that the driver can easily enter and leave the driver's seat and also providing the necessary enclosure and safety for the entire enclosure system.

[0004] However, the driver enclosure design in the prior art has various deficiencies, which not only affect the safety of users but also reduce the comfort and aesthetics of the riding experience.

[0005] Specifically, the current driver enclosure structure is mainly composed of aluminum alloy weldments. Although this construction method provides basic strength and stability, its rough appearance lacks additional protective measures and comfort considerations. The exposed metal edges may cause harm to the driver or other occupants, especially in case of an emergency.

[0006] In addition, during long-distance trips, the tour guide backrest is an essential part of tourist vehicles. It provides the necessary support for tour guides, enabling them to stand steadily and face the passengers to give explanations. However, the existing tour guide backrest designs often draw on the slow-rebound backrest mechanism disclosed in a similar Chinese patent CN215042272U and adopt a rotary structure connected to the driver's enclosure. The above connection method exposes two main drawbacks in practical applications: First, the stability and safety of the rotary connection are relatively low, and it may shift due to vibration during vehicle driving, posing a safety hazard to tour guides and passengers; Second, when the tour guide does not use it, the backrest cannot be completely hidden or retracted, resulting in a messy driver's enclosure area, lacking a sense of neatness and professionalism.

[0007] In view of this, the inventor specifically designed a new type of driver's enclosure structure, and this case came into being. Summary of the Utility Model

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0047] Please refer to Figures 1 to 13 , which is a new driver enclosure structure as the best embodiment of the present utility model.

[0048] Such as Figure 1 , 2 , 3, and 4 show, it includes a rear enclosure assembly 10. The rear enclosure is arranged behind the driver's position and is integrally L-shaped, having a connecting section 11 that is arc-shaped and bent.

[0049] Such as Figure 1 , 2As shown, it further includes a front guardrail assembly 20, which includes a guardrail door 21 hinged to one side of the connection section 11 and a locking structure 22 fixed to the side of the vehicle body instrument panel. The other side of the guardrail door 21 is detachably connected to the locking structure 22;

[0050] A lumbar support cushion assembly 30, which includes a slide rail 31, a lumbar support cushion frame 32 slidably arranged along the slide rail 31, and a locking member 33 for controlling the locking state of the lumbar support cushion frame 32 and the slide rail 31. The slide rail 31 is horizontally arranged along the inner side of the panel section close to the driver's position so that the lumbar support cushion assembly 30 slides telescopically along the bending position of the connection section 11;

[0051] Among them, a decorative panel 12 is provided on the outer side of the rear enclosure assembly 10 away from the driver's position. An upper foamed decorative member 40 is covered on the outer side of the lumbar support cushion assembly 30, and the upper foamed decorative member 40 is provided with a relief opening 41 opposite to the lumbar support cushion assembly 30.

[0052] Specifically, the rear enclosure assembly 10 includes a vertical rod 50, a welded frame 60 vertically fixed to one side of the middle part of the vertical rod 50, and a decorative panel 12 covering the outer side of the welded frame 60. A wall support structure 65 is provided on the side of the welded frame 60 away from the vertical rod 50, and a ground support structure 66 is provided at the bottom of the welded frame 60.

[0053] In this embodiment, the welded frame 60 includes a top rod 61, a middle rod 62, and a bottom rod 63 that are sequentially and parallelly distributed up and down. The top rod 61, the middle rod 62, and the bottom rod 63 are each composed of a straight line segment extending horizontally and a bent segment (not marked in the figure) that is arc-shapedly bent at one end of the straight line segment. The same ends of the top rod 61, the middle rod 62, and the bottom rod 63 away from the bent segment are fixedly connected by a side rod. The end of the bent segment is connected to the vertical rod 50. The decorative panel 12 entirely covers the outer sides of the middle rod 62 and the bottom rod 63 and also forms a curved covering at the bent segment position, thereby forming a curved connection section 11 at the bent segment position.

[0054] Among them, in combination with Figure 1 , the decorative panel 12 is an aluminum-plastic board. A plurality of connecting pieces 67 are respectively fixed to the sides of the middle rod 62 and the bottom rod 63 away from the driver's position. The aluminum-plastic board is fixedly locked to the connecting pieces 67 by bolts. In order to further beautify the connection position of the aluminum-plastic board and form further protection, a lower foamed decorative member 13 is covered on the outer side of the bottom rod 63 to hide the bolts and the corresponding connection structures while forming bottom protection.

[0055] In particular, the top rod 61 and the bottom rod 63 are arranged in the middle of the vertical rod 50. The vertical rod 50 is installed between the door aisle and the roof as a support. The ground support structure 66 is fixed to the lower end of the bottom rod 63 by an L-shaped ground support rod 661, and its height is higher than the bottom of the vertical rod 50 to accommodate the higher passenger seat behind the driver's seat. The wall support structure 65 is used to fix the side of the weldment frame 60 to the side wall inside the vehicle, thereby forming an all-round fixation of the rear enclosure to form a stable safety protection.

[0056] Preferably, Figure 5 , 6 As shown in , 7, the slide rail 31 includes a pair of slide bar fixing plates 311 parallel to each other and a guide slide bar 312 arranged between the slide bar fixing plates 311, the two slide bar fixing plates 311 are arranged between the top rod 61 and the middle rod 62 and make the guide slide bar 312 distributed along the extension direction of the top rod 61, and the lumbar pad frame 32 is slidably set on the guide slide bar 312 through at least two guide sliders 34 distributed front and back along the length direction of the guide slide bar 312.

[0057] Specifically, a square connecting pipe fitting 313 is provided between the top rod 61 and the middle rod 62 and on the side close to the connecting section 11, wherein one sliding rod fixing plate 311 is locked and fixed to the side wall of the connecting pipe fitting 313, and the other sliding rod fixing plate 311 is locked and fixed to the side wall of the side rod. In this embodiment, there are two guide sliding rods 312, which are fixed in parallel between the two sliding rod fixing plates 311.

[0058] like Figure 6 As shown, the side of the lumbar pad frame 32 close to the clearance opening 41 is covered with a flexible pad 321. In order to cooperate with the extension and support of the lumbar pad assembly 30, a part of the reserved area is reserved on the side of the lumbar pad frame 32 away from the clearance opening 41 without being covered with the flexible pad 321. Instead, two groups of guide sliders 34 distributed in a front-to-rear array are fixed inside the reserved area, and the two groups of guide sliders 34 are slidably connected to one of the guide slide bars 312 respectively.

[0059] Furthermore, if Figure 4 , 6As shown, in order to reduce the overall space occupied by the lumbar support cushion assembly 30, the lumbar support cushion framework 32 is designed to include two parallelly distributed support rods 35 and a support surface 36 welded and fixed between the two support rods 35. The support surface 36 is flush welded with the outer sides of the two support rods 35 to form a hollow area (not marked in the figure) between the inner and outer sides of the two support rods 35. Four guide sliders 34 are installed and fixed on the hollow area inside the support surface 36. In addition, a relatively large space is reserved in the thickness design of the side rod. The thickness of the top rod 61 or the middle rod 62 is less than the thickness of the side rod, and the top rod 61 and the middle rod 62 are installed and fixed on the inner side of the side rod close to the driver's position. The lumbar support cushion framework 32 is movably arranged on the outer side of the top rod 61 and the middle rod 62 away from the driver's position, and the sum of the thickness of the support rod 35 and the thickness of the top rod 61 or the middle rod 62 is also less than the thickness of the side rod. The upper foam decorative piece 40 is installed and fixed through the space remaining in the thickness of the side rod to cover and hide the top rod 61, the middle rod 62, the lumbar support cushion assembly 30, and the connecting piece 67 at the bottom of the middle rod 62. Thus, the lumbar support cushion assembly 30 can be integrally hidden in the space corresponding to the thickness of the side rod and the connection section 11, reducing the thickness of the lumbar support cushion assembly 30 to a certain extent and keeping its overall size streamlined.

[0060] As Figure 8 shown, in this embodiment, the shape of the upper foam decorative piece 40 is adapted to the top rod 61 and the middle rod 62, including a horizontal part 42 and an arc-shaped bent part 43. Among them, the arc-shaped bent part 43 covers the sliding path of the lumbar support cushion assembly 30, and a notch (i.e., the relief notch 41) for facilitating the pulling out of the lumbar support cushion assembly 30 is opened at its upper end. One end of the flexible pad 321 also forms an arc-shaped outer surface 322 that can be fitted with the notch and is integrally formed with the arc-shaped bent part 43. Thus, when the lumbar support cushion assembly 30 is completely retracted, its outer surface forms an entire arc-shaped surface with the connection section 11 of the rear enclosure assembly 10, making the lumbar support cushion assembly 30 perfectly hidden in the driver's surrounding structure.

[0061] Preferably, as Figure 5 、 6As shown, the locking member 33 includes an elastic stop pin 331 movably arranged on the lumbar cushion frame 32 and a control pull rope 332 for controlling the retractable state of the elastic stop pin 331. The weldment frame 60 is provided with a plurality of limiting holes 621 along the moving path of the elastic stop pin 331, which are limitedly matched with the elastic stop pin 331 in the extended state. In this embodiment, the limiting hole 621 is opened on the length square of the middle rod 62, the elastic stop pin 331 is arranged above the position of the middle rod 62, the control pull rope 332 is a brake line set of a bicycle, including a brake rope 3321 and a rope set 3322, the flexible pad 321 is retracted at the position of the give way opening 41 to form a give way groove 323, a control flap 324 is pivotally connected in the give way groove 323, a fixing plate 325 is provided on the inner side of the flexible pad 321 and on one side of the control flap 324, another fixing plate 325 is also provided on the upper end of the elastic stop pin 331, and the two ends of the rope set 3322 are connected to each other. The ends are respectively fixed on the two fixing plates 325, and the end of the brake rope 3321 passes through the inner side of the rope set 3322 and is respectively connected to the inner side of the fixing plate 325 and the elastic limiting pin 331. Therefore, when the control flap 324 is flipped from the outside, the brake rope 3321 is pulled to pull up the elastic limiting pin 331 to disengage it from the limiting hole 621. By setting the position and number of the limiting holes, when the lumbar pad assembly 30 moves to the corresponding set position, the elastic limiting pin 331 is automatically inserted into the new limiting hole 621, thereby completing the position fixation of the lumbar pad assembly 30.

[0062] Preferably, Figure 1 , 8 As shown in Figure 9, the outer side of the upper foam decorative part 40 is recessed inward away from the driver's seat to form a mounting groove 44, and a reversible table top 45 is pivoted in the mounting groove 44. The bottom of the table top 45 is pivoted to the mounting groove 44 and the top is detachably connected to the mounting groove 44. In this embodiment, iron sheets 46 are respectively provided on the inner side of the table top 45 and on both sides of its length direction, and a magnetic sheet 47 is provided in the mounting groove 44 opposite to the iron sheet 46. One side of the top of the table top 45 is recessed to form a handle groove 451, and the bottom of the handle groove 451 is recessed to form an inclined handle surface 452. Therefore, the handle groove 451 and the handle surface 452 can facilitate the table top 45 to be flipped down for use, and the magnetic combination of the iron sheet 46 and the magnetic sheet 47 can facilitate the flipping and fixing of the table top 45. Through the table top 45, the function of the upper foam decorative part 40 can be further enriched, so that it can have certain storage functionality while forming protection.

[0063] In particular, a storage groove 453 is recessed on the inner side of the table top 45, and a plurality of parallel strip grooves 454 are provided near the hinge position of the table top 45. A mobile phone can be conveniently placed through the strip grooves 454 to limit the bottom of the mobile phone, so that it can be conveniently leaned against the installation groove 44, thereby increasing the convenience of storage.

[0064] Preferably, as shown in Figure 10 , 11 , as shown in Fig. 12, the guard door 21 includes an upper support 211, a lower support 212, a door shaft 213, a door panel 214 and a lock 215. The door panel 214 is fixed to one side of the door shaft 213, and the door shaft 213 is hinged between the upper support 211 and the lower support 212. The upper support 211 and the lower support 212 are fixed to the side of the connecting section 11. The lock 215 is arranged on the side of the door panel 214 away from the door shaft 213. The locking structure 22 includes a side frame 221 and a lock piece 222 detachably connected to the lock 215.

[0065] Preferably, a torsion spring reset structure 70 is provided between the upper support 211 and the door shaft 213 so that the door panel 214 has a closing tendency to rotate towards the locking structure 22.

[0066] Specifically, as shown in Figure 11 , the upper support 211 includes a horizontal seat 2111 and a side connecting plate 2112. The side connecting plate 2112 is in an arc shape adapted to the outer peripheral surface of the vertical rod 50 and is fixedly locked to the vertical rod 50 by bolts, so that the horizontal seat 2111 is distributed perpendicular to the vertical rod 50. A first mounting hole (not marked in the figure) is opened on the horizontal seat 2111. An upper limit shaft 71 is fixedly locked vertically in the first mounting hole. A hollow shaft cavity 2131 is formed inside the door shaft 213, and an upper limit piece 72 is fixed at the upper end of the shaft cavity 2131. Four limit grooves 721 are opened around the circumference of the upper limit piece 72. The upper limit shaft 71 penetrates into the shaft cavity 2131, and a reset torsion spring 73 is sleeved on the outer peripheral side thereof. The upper end of the reset torsion spring 73 is fixedly connected to the lower end of the upper limit shaft 71, and the lower end of the reset torsion spring 73 is limited in one of the limit grooves 721. End caps 2132 are covered on both the upper and lower sides of the door shaft 213. Thus, when the door panel 214 is opened, the reset torsion spring 73 twists along with the drive of the door shaft 213 and the upper limit piece 72, accumulating elastic potential energy. When the door panel 214 is released, it rotates towards the initial state under the action of the elastic potential energy of the torsion spring to achieve reset.

[0067] To strengthen the structural stability of the reset torsion spring 73, a disc-shaped limit disc is formed at the lower end of the upper limit shaft 71.

[0068] Preferably, an angle limit structure 80 is provided between the lower support 212 and the door shaft 213 to limit the rotation and opening / closing angle of the door panel 214.

[0069] Specifically, as shown in Figure 12As shown in the figure, the lower support 212 includes a base 2121 welded and fixed to the peripheral side of the vertical rod 50. A second mounting hole 2122 is formed in the base 2121. A lower limit shaft 81 is inserted into the second mounting hole 2122. An annular limit edge 82 is provided in the middle of the lower limit shaft 81. And a 1 / 4 cylindrical angle limit seat 83 cut vertically is provided at the top of the lower limit shaft 81. The angle limit seat 83 includes two mutually perpendicular limit surfaces 831 and an arc surface 832 connecting the two limit surfaces 831. The arc surface 832 forms an integral body with the outer surface of the lower limit shaft 81. The convergence position of the limit surfaces 831 is the axis position of the lower limit shaft 81. A lower limit piece 84 is fixed to the lower end of the shaft cavity 2131 of the door shaft 213. A semi-circular angle limit cavity 85 is formed in the middle of the lower limit piece 84. The angle limit cavity 85 includes a straight side and an arc side (not marked in the figure). The center of the angle limit cavity 85 is collinear with the axis of the lower limit shaft 81 and its arc surface is adapted to the arc surface 832 of the angle limit seat 83. Thus, when the door panel 214 rotates, the lower limit piece 84 rotates following the door panel 214 and the door shaft 213. The straight side of the angle limit cavity 85 contacts the two limit surfaces 831 respectively during the rotation process. Finally, the opening and closing angle of the door panel 214 is limited between the included angle range of the two limit surfaces 831. Cooperating with the torsion spring reset structure 70, the opening and closing angle limitation and automatic reset of the door panel 214 are realized.

[0070] In addition, in this embodiment, the lock 215 is installed on the side of the door panel 214 close to the driver's position, and the door panel 214 is an outward-opening type away from the driver's position.

[0071] Particularly, as Figure 3 shown, in order to further hide the lumbar support assembly 30, another decorative panel 14 is covered on the side of the rear enclosure assembly 10 close to the driver's position and at the positions of the top rod 61 and the middle rod 62.

[0072] As Figure 1 shown, a glass plate 15 or an acrylic plate is installed and fixed at the upper end of the welded frame 60 of the rear enclosure assembly 10. In this embodiment, it is a glass plate 15, so as to facilitate the driver to observe the situation inside the vehicle.

[0073] The utility model effectively overcomes the defects existing in the traditional driver's surround structure by introducing the innovative lumbar support assembly 30, improves the comfort and safety of drivers and tour guides, and at the same time enhances the beauty and functionality of the vehicle interior, specifically as follows:

[0074] The present utility model realizes the smooth telescoping of the lumbar support cushion assembly 30 through the slide rail 31, providing a more stable and comfortable support point for the tour guide. Compared with the original rotary structure, it not only improves the stability but also ensures that it can be fully retracted when not in use, keeping the interior space of the vehicle clean and tidy. In addition, through the cooperation between the lumbar support cushion framework 32 and the slide rail 31, the structural strength of the lumbar support cushion assembly 30 is enhanced, and the locking member 33 locks and limits the position of the lumbar support cushion, thereby effectively improving the safety during driving. In particular, by integrally covering the installation position of the lumbar support cushion assembly 30 with the foamed decorative member 40 and adding the decorative panel 12 to the rear enclosure assembly 10, the traditional metal welding parts are optimized, not only decorating and beautifying the outer surface of the lumbar support cushion assembly 30 but also providing an additional protective layer to avoid potential harm to the driver and other passengers caused by the exposed metal edges.

[0075] In addition, through the combination of the control pull rope 332 and the elastic limit pin 331, the operation of the lumbar support cushion assembly 30 becomes simple and intuitive, and locking or releasing can be achieved without complex adjustment steps.

[0076] In addition, the upper foamed decorative member 40 not only improves the appearance texture of the driver's enclosure but also integrates the table board 45, achieving the unity of functionality and aesthetics.

[0077] In addition, the structures of the rear enclosure assembly 10 and the front guardrail assembly 20 are carefully designed. Through the reasonable layout of elements such as the vertical pole 50, the welded part framework 60, the wall support structure 65, and the ground support structure 66, both the firmness of the structure and the light weight and durability are taken into account.

[0078] In particular, the improvement of the guard door 21, such as the addition of the torsion spring reset structure 70 and the angle limit structure 80, not only ensures the smooth opening and closing of the door but also increases the tendency of automatic closing, reduces the risk of accidental opening, and improves the convenience and safety of use.

[0079] The present utility model has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
