no. 1 Embodiment approach ＞

[0020] figure 1 It is a figure which shows the structure which installed the cab floor structure 10 of 1st Embodiment in a vehicle.

[0021] The vehicle has a cab 1 , a rear frame 2 , a front frame 3 , and side frames 4 . The vehicle is, for example, a truck.

[0022] The cab 1 is a box-shaped portion having a driver's seat. The cab 1 has a cab floor structure 10 and a seat 11 . The cab floor structure 10 is a structure for securing the rigidity of the cab floor 100 when a load is applied to the cab floor 100 which is the floor of the cab 1 from the front of the vehicle. Details of the cab floor structure 10 will be described later. The seat 11 is a seat on which a passenger sits. The length of the cab floor structure 10 in the front-rear direction of the vehicle is greater than the length of the seat 11 in the front-rear direction of the vehicle, for example.

[0023] The rear bracket 2 is a member for fixing the rear end side of the bottom surface of the cab 1 to the s...

no. 2 Embodiment approach ＞

[0039] The cab floor structure 10a of the second embodiment differs from the cab floor structure 10 of the first embodiment in that the reinforcing member 110a has a gap between the lower surface of the reinforcing member 110a and the recessed portion 104 .

[0040] Figure 5 An enlarged view showing a cab floor structure 10a of the second embodiment.

[0041] The cab floor structure 10a has a cab floor 100 and a reinforcement member 110a.

[0042] The reinforcing member 110a has a plurality of recesses 111a and protrusions 112a. The plurality of concave portions 111 a of the reinforcement member 110 a are in contact with the plurality of convex portions 103 of the cab floor 100 . The convex portion 112 a of the reinforcing member 110 a is not in contact with the concave portion 104 in all areas, but a gap is provided between the convex portion 112 a and the concave portion 104 . By having such a configuration, the reinforcing member 110 a can increase the rigidity of the c...

Abstract

The present invention provides a cab floor structure that ensures rigidity in a cab floor against loads from the front part of the vehicle. The cab floor structure (10) and a reinforcing member (110),wherein the cab floor structure (10) has a cab floor (100) which forms the floor of the cab (1) of a vehicle, a plurality of convex portions (103) formed in the front-rear direction of the vehicle, and at least one recess ( 104); the reinforcing member (110) is in contact with at least the plurality of convex portions (103) of the cab floor (100). The reinforcing member (110) has a curved surfacewhich is arranged on the cab floor (100) side and a linear surface which is arranged on the side opposite to the cab floor (100).

Description

technical field [0001] The present invention relates to a construction for reinforcing the cab floor of a vehicle. Background technique [0002] A cab floor structure is provided in the vehicle. Patent Document 1 discloses a floor panel structure provided with reinforcing members for reinforcing a central floor panel portion and side floor panel portions. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2010-149620 Contents of the invention [0006] The problem to be solved by the invention [0007] In the prior art, the case where an impact load is applied from the front of the vehicle is not considered. In the case of a cab floor having a concave-convex shape in the front-rear direction of the vehicle, there arises a problem that when a load is applied from the front of the vehicle, the cab floor bends, making it impossible to secure a living space for the driver. [0008] Therefore, the present inven...
