Description

Technical Field

[0001] The present application belongs to the technical field of automobile floors, and specifically relates to a floor structure used in a cab of a new energy truck. Background Art

[0002] With the vigorous development of my country's new energy vehicle industry, various types of new energy vehicles have emerged one after another, and new energy trucks have also increased. Generally, the cab of a truck is divided into the main control area at the front and the driver's seat installation area at the rear. The main control area is used to install the main console, brake plate, accelerator pedal, etc., and the driver's seat installation area is used to install the driver's seat. Since traditional fuel vehicles usually install the engine and radiator in the middle and lower part of the rear section of the cab floor, the floor structure of the traditional fuel vehicle cab usually has an upward bulge in the driver's seat installation area to accommodate the engine and radiator below. Figure 5 The cab of a conventional fuel truck is shown in the figure. It can be seen that there is an upward bulge in the middle of the cab floor 6. New energy trucks do not have engines, and the radiator is usually set together with the motor system located at the rear of the cab. However, the floor structure of the current new energy truck cab is improved on the floor structure of the fuel truck cab, so the bulge still exists, and there is a useless cavity under the bulge, which affects the internal space of the cab. Utility Model Content

[0003] The present application provides a floor structure applied to a cab of a new energy truck to solve the technical problems of an unreasonable floor structure of a cab of a traditional new energy truck and a small internal space of the cab.

[0004] The technical solution adopted in this application is:

[0005] A floor structure applied to a cab of a new energy truck comprises a supporting frame and a bearing shell located on top of the supporting frame, wherein the bearing shell comprises a first bearing portion for bearing a driver's seat and a second bearing portion located behind the first bearing portion, wherein the first bearing portion has a first bearing surface, and the second bearing portion has a second bearing surface, and the first bearing surface is flush with the second bearing surface in the vertical direction.

[0006] The floor structure applied to the cab of a new energy truck described in this application also includes the following additional technical features:

[0007] A left wheel guard and a right wheel guard for accommodating tires are respectively disposed on both sides of the bearing shell, and the left wheel guard and the right wheel guard are both higher than the bearing shell.

[0008] It also includes a vertical enclosing plate connected to the bearing shell, the vertical enclosing plate is located on a side of the second bearing portion away from the first bearing portion and is respectively connected to the left wheel guard and the right wheel guard.

[0009] The vertical enclosing plate is connected to the bearing shell by welding. The bearing shell is provided with an outwardly extending welding portion at the second bearing portion. The vertical enclosing plate includes a vertical plate extending in a vertical direction and a welding flange extending in a horizontal direction.

[0010] The support frame includes a front support beam and a rear support beam, the front support beam and the rear support beam are connected by a longitudinal connecting beam, the front support beam is located at the bottom of the first bearing surface, and the rear support beam is located at the bottom of the second bearing surface.

[0011] The longitudinal connecting beam includes a left longitudinal beam and a right longitudinal beam, the left longitudinal beam is welded to the front supporting cross beam and the rear supporting cross beam respectively, and / or the right longitudinal beam is welded to the front supporting cross beam and the rear supporting cross beam respectively.

[0012] A reinforcing crossbeam is also provided between the front supporting crossbeam and the rear supporting crossbeam, and two ends of the reinforcing crossbeam are respectively welded to the left longitudinal beam and the right longitudinal beam.

[0013] The left longitudinal beam is provided with a left bent portion bent toward the right longitudinal beam at one end close to the front supporting cross beam, and / or the right longitudinal beam is provided with a right bent portion bent toward the left longitudinal beam at one end close to the front supporting cross beam.

[0014] The first bearing portion and the second bearing portion are integrally formed.

[0015] The supporting frame is connected to the bearing shell by welding.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The floor structure applied to the cab of a new energy truck of the present application includes a supporting frame and a bearing shell located on the top of the supporting frame, and the bearing shell includes a first bearing part and a second bearing part. The first bearing part is used to bear the main console and brakes, power pedals, etc., and the second bearing part is used to bear the main driver's seat and the co-driver's seat. Since the first bearing surface and the second bearing surface are flush in the vertical direction, the vertical distance between the second bearing surface and the top of the cab is increased, and a larger vertical space is reserved for the part of the cab corresponding to the second bearing part. The space between the main driver's seat and the co-driver's seat can be used as a storage area, etc., which increases the driver's experience; in addition, since the first bearing surface and the second bearing surface are flush in the vertical direction, there is no bend between the first bearing part and the second bearing part, and the bearing shell is a horizontal plate-like structure as a whole, which reduces the difficulty of manufacturing the bearing shell and helps to enhance the structural strength of the bearing shell. On the premise of ensuring the same structural strength, it helps to reduce the structural strength requirements for the material for manufacturing the bearing shell, thereby helping to reduce the manufacturing cost of the bearing shell.

[0018] 2. As a preferred embodiment of the present application, the two sides of the bearing shell are respectively provided with a left wheel guard and a right wheel guard for accommodating tires, and the left wheel guard and the right wheel guard are both higher than the bearing shell. Since the tires need a certain turning space during the left and right turning process, the left wheel guard and the right wheel guard are provided to provide turning space for the left tire and the right tire located under the floor structure, so as to prevent the tires from scratching the floor structure during the turning process, thereby affecting driving safety; at the same time, since the left wheel guard and the right wheel guard are provided, there is no need to worry about interference with the turning of the tires when designing the vertical installation position of the floor structure, so the vertical installation position of the floor structure in the cab can be adjusted to adapt to different types and different heights of driver's seats, thereby improving the adaptability to the driver's seat; at the same time, when the vertical size of the driver's seat to be installed is large and the floor structure needs to be installed at a lower position in the cab, the vertical height between the second bearing surface and the top of the cab is increased, further widening the usable space in the cab.

[0019] 3. As a preferred embodiment of the present application, the support frame includes a front support beam and a rear support beam, the front support beam and the rear support beam are connected by a longitudinal connecting beam, the front support beam is located at the bottom of the first load-bearing surface, and the rear support beam is located at the bottom of the second load-bearing surface. Since the first bearing surface is used to bear the brake plate and the power pedal, and serves as the driver's leg placement area, and the second bearing surface is used to bear the main driving seat and the co-pilot seat, etc., the first bearing part and the second bearing part both have the function of bearing a certain weight. By respectively arranging the front supporting beam and the rear supporting beam at the bottom of the first bearing surface and the second bearing surface, the bearing capacity of the first bearing part and the second bearing part can be effectively improved, and the structural strength of the floor structure can be increased. The arrangement of the longitudinal connecting beam connects the front supporting beam and the rear supporting beam as a whole. When one of the front supporting beam and the rear supporting beam bears more force, taking the rear supporting beam as an example, when the rear supporting beam bears more force, the longitudinal connecting beam can transfer this part of the force to the front supporting beam, so that the front supporting beam and the rear supporting beam jointly bear the gravity applied to the second bearing part, avoiding the possibility of stress concentration in the bearing shell, thereby improving the supporting stability of the floor structure.

[0038] like Figures 1 to 4 As shown, a floor structure applied to a cab of a new energy truck includes a support frame 1 and a bearing shell 2 located on the top of the support frame 1, the bearing shell 2 includes a first bearing portion for bearing a driver's seat and a second bearing portion located behind the first bearing portion, the first bearing portion has a first bearing surface 21, the second bearing portion has a second bearing surface 22, and the first bearing surface 21 is flush with the second bearing surface 22 in the vertical direction.

[0039] The floor structure applied to the cab of a new energy truck of the present application includes a supporting frame 1 and a bearing shell 2 located on the top of the supporting frame 1, and the bearing shell 2 includes a first bearing part and a second bearing part. The first bearing part is used to bear the main console and brakes, power pedals, etc., and the second bearing part bears the main driver's seat and the co-driver's seat. Since the first bearing surface 21 and the second bearing surface 22 are flush in the vertical direction, the vertical distance between the second bearing surface 22 and the top of the cab is increased, and a larger vertical space is reserved for the part of the cab corresponding to the second bearing part. The space between the main driver's seat and the co-driver's seat can be used as a storage area, etc., which increases the driver's experience. In addition, since the first bearing surface 21 and the second bearing surface 22 are flush in the vertical direction, there is no bend between the first bearing part and the second bearing part, and the bearing shell 2 is a horizontal plate-like structure as a whole, which reduces the difficulty of manufacturing the bearing shell 2 and helps to enhance the structural strength of the bearing shell 2. On the premise of ensuring the same structural strength, it helps to reduce the structural strength requirements for the material for manufacturing the bearing shell 2, thereby helping to reduce the manufacturing cost of the bearing shell 2.

[0040] As a preferred embodiment of the present application, Figure 1 , Figure 3As shown, the left wheel guard 3 and the right wheel guard 4 for accommodating tires are respectively provided on both sides of the bearing shell 2, and the left wheel guard 3 and the right wheel guard 4 are both higher than the bearing shell 2. Since the tires need a certain turning space during the left and right turning process, the left wheel guard 3 and the right wheel guard 4 are provided to provide turning space for the left and right tires located under the floor structure, so as to prevent the tires from scratching the floor structure during the turning process, thereby affecting the driving safety; at the same time, since the left wheel guard 3 and the right wheel guard 4 are provided, there is no need to worry about the interference with the turning of the tires when designing the vertical installation position of the floor structure, so the vertical installation position of the floor structure in the cab can be adjusted to adapt to different types and different heights of driver's seats, thereby improving the adaptability to the driver's seat; in addition, when the vertical size of the driver's seat to be installed is large and the floor structure needs to be installed at a lower position in the cab, the vertical height between the second bearing surface 22 and the top of the cab is increased, further widening the usable space in the cab. Furthermore, as people's current requirements for the quality of their peers increase, the requirements for the shockproof effect of vehicles are getting higher and higher. Some airbag seats with shock-absorbing function can effectively reduce the degree of bumps experienced by passengers in the driver's seat. The shock-absorbing effect of this airbag seat is related to the size of the airbag. The larger the airbag, the higher the vertical height of the airbag seat, and the larger the vertical installation space required. Under this embodiment, the load-bearing shell 2 can freely adjust the vertical installation position within a certain range, so it can better meet the installation requirements of the airbag seat and enhance the riding experience of the passengers.

[0041] Preferably, the left wheel guard cover 3 and the right wheel guard cover 4 are both connected to the bearing shell 2 by welding. The left wheel guard cover 3 and the right wheel guard cover 4 are welded to the top of the bearing shell 2.

[0042] As a preferred embodiment of this implementation, Figure 3 As shown, it also includes a vertical enclosing plate 5 connected to the bearing shell 2, the vertical enclosing plate 5 is located on the side of the second bearing part away from the first bearing part and is respectively connected to the left wheel guard 3 and the right wheel guard 4. By providing the vertical enclosing plate 5, the bearing shell 2 and the cab can be connected as a relatively sealed whole, reducing the probability of a gap between the bearing shell 2 and the side wall of the cab, etc., on the one hand, it plays a role in improving the sealing of the cab, and on the other hand, the vertical enclosing plate 5 connects the left wheel guard 3 and the right wheel guard 4 as a whole, increases the tightness of the connection between the left wheel guard 3 and the right wheel guard 4, and improves the installation stability of the left wheel guard 3 and the right wheel guard 4.

[0043] As a preferred example under this embodiment, Figure 4As shown, the vertical enclosing plate 5 is connected to the bearing shell 2 by welding, the bearing shell 2 is provided with an outwardly extending welding portion 23 at the second bearing portion, and the vertical enclosing plate 5 includes a vertical plate 51 extending in the vertical direction and a welding flange 53 extending in the horizontal direction.

[0044] The vertical enclosing plate 5 is installed on the bearing shell 2 by welding, which improves the connection strength between the vertical enclosing plate 5 and the bearing shell 2. When the vehicle is bumpy or shaken during driving, the sealing stability of the vertical enclosing plate 5 to the interior space of the cab can be guaranteed. In addition, when assembling the floor structure, the supporting frame 1 and the bearing shell 2 are usually installed inside the cab before the subsequent components are installed. When welding the vertical enclosing plate 5, the welding portion 23 and the welding flange 53 are provided so that the welding position between the vertical enclosing plate 5 and the bearing shell 2 is located on the outside of the second bearing portion relative to the first bearing portion. The operator can perform the welding operation on the vertical enclosing plate 5 from outside the cab, which greatly reduces the restrictions on the welding operation in the working space, thereby greatly reducing the difficulty of welding and helping to improve the installation efficiency of the vertical enclosing plate 5.

[0045] As a preferred embodiment of the present application, Figure 2 As shown, the support frame 1 includes a front support beam 11 and a rear support beam 12, and the front support beam 11 and the rear support beam 12 are connected by a longitudinal connecting beam. The front support beam 11 is located at the bottom of the first bearing surface 21, and the rear support beam 12 is located at the bottom of the second bearing surface 22. Since the first bearing surface 21 is used to bear the brake pedal and the power pedal, and serves as the driver's leg placement area, and the second bearing surface 22 is used to bear the main driving seat and the co-pilot seat, etc., the first bearing part and the second bearing part both have the function of bearing a certain weight. By respectively arranging the front supporting beam 11 and the rear supporting beam 12 at the bottom of the first bearing surface 21 and the second bearing surface 22, the bearing capacity of the first bearing part and the second bearing part can be effectively improved, and the structural strength of the floor structure can be increased. The arrangement of the longitudinal connecting beam connects the front supporting beam 11 and the rear supporting beam 12 as a whole. When one of the front supporting beam 11 and the rear supporting beam 12 bears more force, for example, the rear supporting beam 12 bears more force, the longitudinal connecting beam can transfer this part of the force to the front supporting beam 11, so that the front supporting beam 11 and the rear supporting beam 12 jointly bear the gravity applied to the second bearing part, avoiding the possibility of stress concentration in the bearing shell 2, thereby improving the supporting stability of the floor structure.

[0046] As a preferred embodiment of this implementation, Figure 2As shown, the longitudinal connecting beam includes a left longitudinal beam 13 and a right longitudinal beam 14, the left longitudinal beam 13 is welded to the front supporting beam 11 and the rear supporting beam 12 respectively, and / or the right longitudinal beam 14 is welded to the front supporting beam 11 and the rear supporting beam 12 respectively. By providing the left longitudinal beam 13 and the right longitudinal beam 14, the connection strength between the front supporting beam 11 and the rear supporting beam 12 is improved, and at the same time, a transmission channel is added for the stress transfer between the front supporting beam 11 and the rear supporting beam 12, further reducing the possibility of stress concentration in the support frame 1; in addition, the left longitudinal beam 13 and the right longitudinal beam 14 are respectively connected to the front supporting beam 11 and the rear supporting beam 12 by welding. On the one hand, the welding connection method can reduce the difficulty of installing the left longitudinal beam 13 and the right longitudinal beam 14, and on the other hand, welding can improve the connection strength between the left longitudinal beam 13 and the right longitudinal beam 14 and the front supporting beam 11 and the rear supporting beam 12; furthermore, the left longitudinal beam 13 and the right longitudinal beam 14 themselves can also play a bearing and supporting role for the gravity transmitted by the load-bearing shell 2, further improving the structural strength of the support frame 1.

[0047] As a preferred example under this embodiment, Figure 2 As shown, a reinforcing crossbeam 15 is further provided between the front supporting crossbeam 11 and the rear supporting crossbeam 12, and the two ends of the reinforcing crossbeam 15 are respectively welded to the left longitudinal beam 13 and the right longitudinal beam 14. By providing the reinforcing crossbeam 15, on the one hand, the contact area between the supporting frame 1 and the load-bearing shell 2 can be increased, and the stress transmission area from the load-bearing shell 2 to the supporting frame 1 can be increased, thereby improving the supporting stability of the supporting frame 1 for the load-bearing shell 2. On the other hand, the reinforcing crossbeam 15 also adds a new stress transmission channel between the left longitudinal beam 13 and the right longitudinal beam 14. When the gravity borne by the left longitudinal beam 13 or the right longitudinal beam 14 is uneven, the reinforcing crossbeam 15 can play a role in stress transmission between the left longitudinal beam 13 and the right longitudinal beam 14, thereby reducing the possibility of stress concentration in the left longitudinal beam 13 or the right longitudinal beam 14.

[0048] As another preferred example under this embodiment, Figure 2 As shown, the left longitudinal beam 13 is provided with a left bent portion 131 bent toward the right longitudinal beam 14 at one end close to the front supporting cross beam 11, and / or the right longitudinal beam 14 is provided with a right bent portion 141 bent toward the left longitudinal beam 13 at one end close to the front supporting cross beam 11. Since the cab needs to be provided with other components such as support components or steering components, a certain installation space is required. By providing the left bent portion 131 and the right bent portion 141, assembly space is reserved for other components of the cab, reducing the probability of the floor structure interfering with the installation of the cab components, so that the floor structure of the present application can have a better adaptability to cabs of different structural forms.

[0049] As a preferred embodiment of the present application, the first bearing part and the second bearing part are integrally formed. The first bearing part and the second bearing part are integrally formed, which, on the one hand, improves the structural strength of the bearing shell 2 and helps to improve the bearing stability of the bearing shell 2; on the other hand, it saves the operation of connecting and assembling the first bearing part and the second bearing part after they are separately manufactured and formed, which helps to simplify the assembly process of the floor structure and improve the assembly efficiency of the floor structure.

[0050] The present application does not limit the structural form of the bearing shell 2, and the first bearing part and the second bearing part may also be manufactured separately and then connected together by welding or other methods.

[0051] As a preferred embodiment of the present application, the support frame 1 is connected to the load-bearing shell 2 by welding. Connecting the support frame 1 and the load-bearing shell 2 by welding can effectively improve the tightness of the connection between the support frame 1 and the load-bearing shell 2, and reduce the possibility of relative displacement between the support frame 1 and the load-bearing shell 2 when the vehicle shakes or bumps during the vehicle operation.

[0052] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0053] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0054] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
