Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0002] An all-terrain vehicle (ATV) is a vehicle designed to travel on a variety of complex terrains. ATVs have strong off-road capabilities and can easily handle complex terrains such as mud, sand, snow, and rocks.

[0003] All-terrain vehicles typically include a frame, body panels, running gear, suspension system, powertrain, transmission system, and seat. The frame includes longitudinal beams that support the all-terrain vehicle. In existing technology, the longitudinal beams have relatively low structural strength, resulting in insufficient structural strength, reduced impact resistance, and consequently, compromised safety of the all-terrain vehicle.

[0004] Therefore, improving the safety of all-terrain vehicles is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this application is to provide an all-terrain vehicle with higher safety.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An all-terrain vehicle includes a frame, a running gear, a suspension system, a powertrain, and doors. The running gear is at least partially located below the frame. The suspension system connects the running gear to the frame. The powertrain is supported by the frame and driven by the running gear. The doors include a door body connected to the frame and a sealing structure for sealing a gap between the door body and the frame. The frame includes a roof support structure including a longitudinal beam extending substantially along the length of the frame. The longitudinal beam is at least partially recessed to form a first recess and a second recess for increasing the strength of the longitudinal beam structure. The first and second recesses extend substantially along the length of the frame. The first recess includes a sealing surface substantially perpendicular to the width of the frame. When the door body is closed, the sealing structure is located between the sealing surface and the door body.

[0008] Furthermore, the first recess includes a gap surface that is substantially perpendicular to the sealing surface, and when the door body is in the closed state, the distance between the door body and the gap surface along the height direction of the vehicle frame is equal everywhere.

[0009] Furthermore, a longitudinal plane perpendicular to the width direction of the frame and passing through the center of the frame width is defined. The first recess is located on the side of the longitudinal beam away from the longitudinal plane and is located at the lower part of the longitudinal beam. The second recess is located on the side of the longitudinal beam close to the longitudinal plane and is located at the upper part of the longitudinal beam.

[0010] Furthermore, a longitudinal plane perpendicular to the width direction of the frame and passing through the center of the frame width is defined. The longitudinal beam includes a first mating part and a second mating part located between the first recess and the second recess. The first mating part is located on the side of the longitudinal beam away from the longitudinal plane, and the second mating part is located on the side of the longitudinal beam close to the longitudinal plane. The side of the first recess away from the longitudinal plane and the side of the second recess away from the longitudinal plane are connected by the first mating part, and the side of the first recess close to the longitudinal plane and the side of the second recess close to the longitudinal plane are connected by the second mating part.

[0011] Furthermore, the all-terrain vehicle includes a first canopy, which is at least partially located within and fixed to the second recess.

[0012] Furthermore, the longitudinal beam includes a first longitudinal beam and a second longitudinal beam distributed along the width direction of the vehicle frame. Both the first longitudinal beam and the second longitudinal beam include a second recess. The first roof is fixed on both sides along the width direction of the vehicle frame through the second recess of the first longitudinal beam and the second recess of the second longitudinal beam, respectively.

[0013] Furthermore, the all-terrain vehicle includes a second canopy that at least partially covers the first mating part and is fixedly connected to the first mating part.

[0014] Furthermore, the first mating part has a fixing surface that is substantially perpendicular to the height direction of the frame, and a threaded sleeve is built into the first mating part. The threaded sleeve is also located on the fixing surface, and the second canopy is fixedly connected to the threaded sleeve by fasteners.

[0015] Furthermore, the all-terrain vehicle also includes a driver's cab and a handle located inside the driver's cab. The second mating part has a mounting surface facing the driver's cab, and the acute angle opening formed by the mounting surface and the longitudinal plane faces downward. The handle is fixed to the mounting surface.

[0016] Furthermore, the all-terrain vehicle also includes a driver's cab and an interior panel fixed to the roof structure. The second mating part has a mounting surface facing the driver's cab, and the acute angle opening formed by the mounting surface and the longitudinal plane faces downward. The interior panel is at least partially attached to the mounting surface.

[0017] The first and second recesses in the aforementioned all-terrain vehicle can disperse the stress in the longitudinal beams, thereby improving the structural strength of the longitudinal beams, enhancing their impact resistance, and ultimately improving the safety of the all-terrain vehicle.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0032] like Figures 1 to 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, and a powertrain 15.

[0033] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0034] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panels 12, the running gear 13, the suspension system 14, and the powertrain 15. The body panels 12 are at least partially connected to the frame 11. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. Specifically, the running gear 13 includes a front wheel 131 and a rear wheel 132, both of which are connected to the frame 11 via the suspension system 14. The powertrain 15 is drive-connected to the running gear 13; specifically, the powertrain 15 can be drive-connected to at least one of the front wheel 131 or the rear wheel 132.

[0035] Specifically, the frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 connected in sequence. Along the length of the frame 11, the middle frame 112 is located between the front frame 111 and the rear frame 113. The body panel 12 is at least partially connected to the middle frame 112 and forms a driver's cab 20 with the middle frame 112, the driver's cab 20 being used to provide seating space for the driver and / or passengers.

[0036] In this embodiment, the mid-frame 112 includes a front strut 1121, a strut 1122, and a rear strut 1123. The strut 1122 is located between the front strut 1121 and the rear strut 1123. For the all-terrain vehicle 100, the front strut 1121 is the A-pillar of the all-terrain vehicle 100, the strut 1122 is the B-pillar of the all-terrain vehicle 100, and the rear strut 1123 is the C-pillar of the all-terrain vehicle 100.

[0037] like Figure 3 and Figure 4 As shown, in one embodiment, the frame 11 includes a side support 118 for the driver and passengers to step on. The side support 118 extends at least partially along the length of the frame 11 and is fixedly connected to the center frame 112. Specifically, a longitudinal plane 101 is defined perpendicular to the width direction of the frame 11 and passes through the center of the width of the frame 11. The maximum distance between the center frame 112 and the longitudinal plane 101 along the width direction of the frame 11 is less than the maximum distance between the side support 118 and the longitudinal plane 101 along the width direction of the frame 11. This arrangement facilitates the driver and passengers getting on and off the vehicle by using the side support 118, thereby improving the convenience of getting on and off the vehicle for the driver and / or passengers, and ultimately enhancing the usability of the all-terrain vehicle 100.

[0038] In one implementation, the side brackets 118 are located on at least one side of the cab 20 along the width direction of the frame 11. It should be noted that when the side brackets 118 are located on either side of the cab 20, both side brackets 118 can meet the entry and exit needs of personnel on both sides of the all-terrain vehicle 100, thereby improving the convenience of the all-terrain vehicle 100. When the side brackets 118 are located on one side of the cab 20, one side bracket 118 is sufficient to meet the entry and exit needs of the all-terrain vehicle 100. Furthermore, installing one side bracket 118 can reduce the cost of the all-terrain vehicle 100. Therefore, this application does not limit the number of side brackets 118 installed on either side of the cab 20.

[0039] Specifically, one end of the side bracket 118 is connected to the front support column 1121, and the other end of the side bracket 118 is connected to the rear support column 1123. In one embodiment, the side bracket 118 is welded to the front support column 1121 and the rear support column 1123 respectively, thereby improving the connection stability between the side bracket 118 and the front support column 1121 and the rear support column 1123.

[0040] More specifically, the side bracket 118 is also connected to the support column 1122. In some embodiments, the support column 1122 and the side bracket 118 are connected by a connecting pipe, and the connecting pipe is welded to the support column 1122 and the side bracket 118 respectively. This arrangement can further improve the connection stability between the side bracket 118 and the frame 11.

[0041] More specifically, the frame 11 also includes a bottom frame 116, located at the lower part of the frame 11, for providing support for the all-terrain vehicle 100; that is, the bottom frame 116 is the chassis of the all-terrain vehicle 100. Side supports 118 are also connected to the bottom frame 116. This arrangement improves the connection stability between the side supports 118 and the frame 11, enabling the side supports 118 to withstand greater weight. In some embodiments, the bottom frame 116 and the side supports 118 are connected by connecting pipes, and the connecting pipes are welded to both the bottom frame 116 and the side supports 118, thereby improving the connection stability between the side supports 118 and the bottom frame 116.

[0042] In one embodiment, the vehicle body panel 12 includes a foot pedal 123. The foot pedal 123 is for the driver and / or passenger to step on. A plurality of mounting brackets 1181 are provided on the side support 118, and the foot pedal 123 covers the side support 118 and is fixedly connected to the mounting brackets 1181. In this embodiment, the foot pedal 123 has a flat surface for the driver and / or passenger to step on. This arrangement increases the stepping area of ​​the driver and passenger on the side support 118, thereby facilitating the use of leverage by the occupants.

[0043] Specifically, a reinforcing rib 1231 is formed within the foot pedal 123, and the reinforcing rib 1231 is arranged around and abuts against the side support 118. This arrangement improves the structural strength of the foot pedal 123. Simultaneously, the reinforcing rib 1231 allows the side support 118 to support the foot pedal 123, further enhancing its structural strength and enabling it to withstand greater weight.

[0044] In one embodiment, the body panel 12 includes a bottom cladding panel 124, which is fixedly connected to the bottom frame 116 to form the bottom of the cockpit 20 for supporting the driver and passengers. The bottom cladding panel 124 is also fixedly connected to a mounting bracket 1181. This arrangement allows the mounting bracket 1181 to integrate multiple mounting points connected to the bottom cladding panel 124, simplifying the mounting point structure on the bottom frame 116. Simultaneously, the mounting bracket 1181 also improves the stability of the bottom cladding panel 124.

[0045] Specifically, the mounting bracket 1181 is provided with a first mounting point 1181a for fixing the foot pedal 123, and a second mounting point 1181b for fixing the bottom cover plate 124. In some embodiments, the first mounting point 1181a and the second mounting point 1181b are the same mounting point. This arrangement simplifies the structure of the mounting bracket 1181, thereby improving its processing efficiency; it also reduces the number of mounting points on the mounting bracket 1181, further simplifying its structure. Furthermore, using a single fastener to install the mounting bracket 1181, foot pedal 123, and bottom cover plate 124 simplifies the assembly process, thus improving the ease of assembly of the all-terrain vehicle 100.

[0046] In this embodiment, the mounting bracket 1181 has at least one weight-reduction hole 1181c, which is located near the first mounting point 1181a. This arrangement helps to reduce the weight of the mounting bracket 1181, thereby making the all-terrain vehicle 100 lighter.

[0047] like Figures 5 to 7 As shown, in one embodiment, the all-terrain vehicle 100 also includes a door 22, which is supported by a frame 11. The door 22 includes a door body 221 and a sealing structure 222. The door body 221 is connected to the frame 11, and the sealing structure 222 is used to seal the gap between the door body 221 and the frame 11. The frame 11 includes a roof support structure 115. Specifically, the roof support structure 115 is located above the front frame 111, the middle frame 112, and the rear frame 113, and is connected to the front frame 111, the middle frame 112, and the rear frame 113, respectively. The all-terrain vehicle 100 also includes a body sealing structure 24, which is used to seal the all-terrain vehicle 100. The body sealing structure 24 includes a canopy 242, which is at least partially mounted on the roof support structure 115 so that the roof support structure 115 can support the canopy 242.

[0048] The top beam structure 115 includes a longitudinal beam 1151 extending substantially along the length of the frame 11. The longitudinal beam 1151 is at least partially recessed to form a first recess 1151c and a second recess 1151d. The first recess 1151c and the second recess 1151d enhance the structural strength of the longitudinal beam 1151, and both recesses extend substantially along the length of the frame 11. This configuration allows for stress dispersion in the longitudinal beam 1151 via the first recess 1151c and the second recess 1151d, thereby increasing the structural strength of the longitudinal beam 1151 and improving its impact resistance, thus enhancing the safety of the all-terrain vehicle 100. Furthermore, the first recess 1151c and the second recess 1151d increase the structural strength of the longitudinal beam 1151 without increasing its thickness, achieving weight reduction of the longitudinal beam 1151.

[0049] Specifically, the first recess 1151c includes a sealing surface 1151e, which is substantially perpendicular to the width direction of the frame 11. When the door body 221 is in the closed state, the sealing structure 222 is located between the sealing surface 1151e and the door body 221. This arrangement ensures that the sealing surface 1151e is substantially on the same plane, thereby preventing the sealing structure 222 from being misaligned on the sealing surface 1151e. This, in turn, improves the sealing performance between the sealing structure 222 and the sealing surface 1151e, thus enhancing the sealing performance between the frame 11 and the door body 221.

[0050] More specifically, the first recess 1151c includes a gap surface 1151f, which is substantially perpendicular to the sealing surface 1151e. Furthermore, when the door body 221 is closed, the distance between the door body 221 and the gap surface 1151f along the height direction of the frame 11 is equidistant. This arrangement helps to ensure more uniform airflow between the door body 221 and the gap surface 1151f during the operation of the all-terrain vehicle 100, thereby reducing noise generated during operation and improving the NHV (Noise, Vibration, and Harshness) performance of the all-terrain vehicle 100. In addition, through the above arrangement, interference from the gap surface 1151f during the opening and closing of the door body 221 can be avoided, thus improving the smoothness of the door body 221's opening and closing. It should be noted that the gap surface 1151f in this application is perpendicular to the height direction of the frame 11.

[0051] In one implementation, a longitudinal plane 101 is defined, perpendicular to the width direction of the frame 11 and passing through the center of the width of the frame 11. A first recess 1151c is located on the side of the longitudinal beam 1151 away from the longitudinal plane 101, and is situated at the lower part of the longitudinal beam 1151. A second recess 1151d is located on the side of the longitudinal beam 1151 close to the longitudinal plane 101, and is situated at the upper part of the longitudinal beam 1151. This arrangement allows the first recess 1151c to be located on the outer side of the frame 11, i.e., on the side away from the driver's compartment 20, so that the sealing surface 1151e can cooperate with the door body 221 for sealing. Meanwhile, the second recess 1151d is located on the inner side of the frame 11, that is, on the side closer to the driver's cab 20, which facilitates the connection between the second recess 1151d and other components of the all-terrain vehicle 100, such as the roof 242. Furthermore, through the above arrangement, the first recess 1151c and the second recess 1151d can be symmetrically distributed on the longitudinal beam 1151, thereby avoiding a reduction in the structural strength of the longitudinal beam 1151 due to their close proximity. This improves the structural strength and operational stability of the longitudinal beam 1151, thus enhancing the safety and structural strength of the all-terrain vehicle 100.

[0052] In another embodiment, the longitudinal beam 1151 further includes a first mating portion 1151g and a second mating portion 1151h. The first mating portion 1151g and the second mating portion 1151h are located between the first recess 1151c and the second recess 1151d, and are used to connect the first recess 1151c and the second recess 1151d. Specifically, the first mating portion 1151g is located on the side of the longitudinal beam 1151 away from the longitudinal plane 101, i.e., the first mating portion 1151g is located on the side of the longitudinal beam 1151 away from the cockpit 20; the second mating portion 1151h is located on the side of the longitudinal beam 1151 closer to the longitudinal plane 101, i.e., the second mating portion 1151h is located on the side of the longitudinal beam 1151 closer to the cockpit 20. The side of the first recess 1151c away from the longitudinal plane 101 is connected to the side of the second recess 1151d away from the longitudinal plane 101 via a first mating part 1151g. The side of the first recess 1151c near the longitudinal plane 101 is connected to the side of the second recess 1151d near the longitudinal plane 101 via a second mating part 1151h. With this configuration, the first mating part 1151g and the second mating part 1151h can connect and support the first recess 1151c and the second recess 1151d.

[0053] In this embodiment, the ceiling 242 includes a first ceiling 2421 (see reference 2421). Figure 8 and Figure 9 ) or second canopy 2422 (refer to) Figure 6 and Figure 7 ).

[0054] like Figure 8 and Figure 9 As shown, in one embodiment, when the roof 242 includes a first roof 2421, the first roof 2421 is at least partially located within and fixed to the second recess 1151d. This arrangement allows the first roof 2421 to be directly connected to the longitudinal beam 1151, thus avoiding the need for additional mounting points on the frame 11 for connection with the first roof 2421, thereby simplifying the overall structure of the frame 11. In some embodiments, the first roof 2421 and the second recess 1151d are fixed with screws to ensure a stable connection between them.

[0055] Specifically, the longitudinal beam 1151 includes a first longitudinal beam 1151a and a second longitudinal beam 1151b distributed along the width direction of the frame 11. Both the first longitudinal beam 1151a and the second longitudinal beam 1151b include a second recess 1151d. The first roof 2421 is fixed on both sides along the width direction of the frame 11 via the second recesses 1151d of the first longitudinal beam 1151a and the second recesses 1151d of the second longitudinal beam 1151b. This arrangement allows the second recesses 1151d on the first longitudinal beam 1151a and the second longitudinal beam 1151b to support both sides of the first roof 2421 along the width direction of the frame 11, thereby improving the connection stability between the first roof 2421 and the longitudinal beam 1151. In addition, the second recess 1151d on the first longitudinal beam 1151a and the second longitudinal beam 1151b can limit the first roof 2421 along the width direction of the frame 11, thereby further improving the connection stability between the first roof 2421 and the first longitudinal beam 1151a and the second longitudinal beam 1151b.

[0056] like Figure 6 and Figure 7As shown, in another embodiment, when the canopy 242 includes a second canopy 2422, the second canopy 2422 at least partially covers the first mating portion 1151g and is fixedly connected to the first mating portion 1151g. This arrangement allows the second canopy 2422 to be directly connected to the longitudinal beam 1151, thus avoiding the need for additional mounting points on the frame 11 for connection to the second canopy 2422, thereby simplifying the overall structure of the frame 11. Furthermore, by placing the second canopy 2422 on the first mating portion 1151g away from the cab 20, more mounting space can be reserved on the longitudinal beam 1151 on the side closer to the cab 20, which facilitates the installation of other components of the all-terrain vehicle 100 on the longitudinal beam 1151.

[0057] Specifically, the first mating part 1151g has a fixing surface 1151i, which is substantially perpendicular to the height direction of the frame 11. A threaded sleeve is built into the first mating part 1151g and is also located on the fixing surface 1151i. The second canopy 2422 is fixedly connected to the threaded sleeve by fasteners. In some embodiments, the fasteners can be screws, which engage with the threaded sleeve to fix the second canopy 2422 to the first mating part 1151g, thereby improving the connection stability between the second canopy 2422 and the longitudinal beam 1151. Furthermore, making the fixing surface 1151i substantially perpendicular to the height direction of the frame 11 allows it to be a plane, facilitating the machining of mounting points on the fixing surface 1151i, such as for installing the threaded sleeve. This arrangement improves the ease of installation between the threaded sleeve and the fixing surface 1151i. Furthermore, the fixing surface 1151i perpendicular to the height direction of the frame 11 can fit better with the second roof 2422, which helps to improve the assembly compactness of the second roof 2422 and the longitudinal beam 1151, and also helps to improve the sealing between the second roof 2422 and the longitudinal beam 1151.

[0058] In one embodiment, the all-terrain vehicle 100 also includes a handle (not shown) located inside the driver's cab 20. The handle allows the driver and passenger to grip it, thus facilitating their balance. The second mating part 1151h has a mounting surface 1151j facing the driver's cab 20. The acute angle opening formed by the mounting surface 1151j and the longitudinal plane 101 faces downwards, and the handle is fixed to the mounting surface 1151j. This arrangement allows the handle connected to the mounting surface 1151j to face the driver or passenger, facilitating gripping and improving ease of use. Furthermore, in this embodiment, the mounting surface 1151j is a plane, which facilitates machining mounting points for the handle on the mounting surface 1151j, thereby improving the ease of assembly between the handle and the longitudinal beam 1151. It should be noted that mounting points for other components can also be added to the mounting surface 1151j to allow the longitudinal beam 1151 to connect with other components.

[0059] In another embodiment, the body panel 12 also includes an interior trim panel 126. The interior trim panel 126 is fixed to the roof support structure 115 and is used to improve the sound insulation and heat insulation of the all-terrain vehicle 100. The second mating part 1151h has a mounting surface 1151j facing the driver's cabin 20. The acute angle opening formed by the mounting surface 1151j and the longitudinal plane 101 faces downwards, and the interior trim panel 126 is at least partially in contact with the mounting surface 1151j. In this embodiment, the mounting surface 1151j is a plane, which allows the interior trim panel 126 to fit more closely to the mounting surface 1151j, avoiding gaps between the interior trim panel 126 and the longitudinal beam 1151, thereby improving the assembly compatibility between the interior trim panel 126 and the longitudinal beam 1151. Furthermore, mounting points for connecting the interior trim panel 126 can be added to the mounting surface 1151j to allow the interior trim panel 126 to be fixedly connected to the longitudinal beam 1151. In this embodiment, since the mounting surface 1151j is a plane, it is advantageous to process mounting points on the mounting surface 1151j and to improve the connection stability at the mounting points. In some embodiments, the interior panel 126 is fixedly connected to the mounting surface 1151j by screws, so that the interior panel 126 and the mounting surface 1151j can be stably connected.

[0060] like Figure 10 and Figure 11As shown, in one embodiment, the interior panel 126 is at least partially fixed to the longitudinal beam 1151. The interior panel 126 has at least one notch 1261, which overlaps with the longitudinal beam 1151 in at least one direction. A grip portion 1151k is formed on the portion of the longitudinal beam 1151 that overlaps with the notch 1261. This arrangement facilitates gripping by the driver and passengers within the cockpit 20, enabling the grip portion 1151k to function as a handle, thereby helping the driver and passengers maintain their balance. Furthermore, in this embodiment, there is no need to additionally install a handle structure on the longitudinal beam 1151, thus eliminating the need for fasteners to assemble the grip portion 1151k and preventing it from falling off, thereby improving the connection stability of the grip portion 1151k. In addition, the above arrangement also simplifies the structure of the all-terrain vehicle 100, thereby improving the space utilization of the all-terrain vehicle 100.

[0061] The all-terrain vehicle 100 also includes seat 19 (see reference). Figure 1 Specifically, seat 19 includes a front seat 191 and a rear seat 192. Notch 1261 includes a first notch 1261a and a second notch 1261b. The first notch 1261a is located near the front seat 191, and the second notch 1261b is located near the rear seat 192. This arrangement allows the grip portion 1151k formed at the first notch 1261a to be easily held by occupants of the front seat 191; the grip portion 1151k formed at the second notch 1261b is also easily held by occupants of the rear seat 192, thus enabling occupants of both the front and rear seats 191 to stabilize their balance by gripping the grip portion 1151k.

[0062] More specifically, there are two of each of the first notch 1261a and the second notch 1261b. The two first notches 1261a are located on both sides of the front seat 191 along the width direction of the frame 11, and the two second notches 1261b are located on both sides of the rear seat 192 along the width direction of the frame 11. This arrangement allows occupants on both sides of the front seat 191 and the rear seat 192 to hold onto the gripping part 1151k, thus enabling occupants of the all-terrain vehicle 100 to stabilize their body balance by holding onto the gripping part 1151k.

[0063] In this embodiment, the notch 1261 exposes the second recess 1151d, which forms a grip portion 1151k. This arrangement, since the second recess 1151d is at least partially recessed within the longitudinal beam 1151, increases the contact area when the driver and passenger grip the grip portion 1151k, thereby improving grip stability. Furthermore, since the second recess 1151d is only a component of the longitudinal beam 1151, and the notch 1261 only exposes a portion of the second recess 1151d without exposing the entire longitudinal beam 1151, the area of ​​the notch 1261 on the interior panel 126 is reduced, improving the integrity of the interior panel 126, enhancing its structural strength, and ultimately improving the protection of the interior panel 126 for the passenger compartment 20.

[0064] As an optional implementation, the opening of the notch 1261 is oriented towards the cockpit 20. This arrangement facilitates the driver and passengers in gripping the exposed grip portion 1151k through the opening of the notch 1261, thereby improving the convenience for the driver and passengers in gripping the grip portion 1151k.

[0065] In this application, when the driver and passengers get on and off the vehicle, they can simultaneously step on the side support 118 and hold the grip part 1151k, which helps them maintain their balance and improves their safety when getting on and off the vehicle. Furthermore, in this application, goods can be loaded on the canopy 242. When personnel are loading or unloading goods from the canopy 242, they can also maintain their balance by holding the grip part 1151k, thereby improving their safety during loading and unloading.

[0066] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
