The utility model embodiment provides a kind of front bumper check apron, be arranged at cab assembly and bumper assembly it
Between, the check apron includes skeleton and the elastomeric overmold part that links together with the skeleton by quadric injection mould, on the skeleton
Portion is provided with notch section in the position interferenceed with the cab assembly and electrical harness, and the skeleton is by being formed in skeleton
The mounting hole of one end and fixed on the bumper assembly, the outer edge of the skeleton is provided with cladding slot, the elasticity bag
Cover the external visible location that part is integrally covered in the skeleton by the cladding slot.
Optionally, multiple bonding holes are provided on the skeleton.
Optionally, the ball indentation hardness of the skeleton is 25-35MPa.
Optionally, the elastomeric overmold part is TPE coverings, and shore a hardness is 70 ± 5HA.
Compared with prior art, the front bumper check apron that the utility model embodiment provides is by skeleton and elastomeric overmold part two
Secondary injection is formed, and the notch for preventing generating interference with driver's cabin and electrical harness during driver's cab turnover is provided on skeleton
Portion, so as to prevent the interference between check apron and driver's cabin.In addition, the external position in skeleton integrally covers elastomeric overmold
Part so that non-notch outside check apron prevents inner body exposed to outer.

Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
Fig. 1 is the front bumper check apron that the utility model embodiment provides using layout drawing；Fig. 2 is real for the utility model
The structure diagram of the front bumper check apron of example offer is provided；Fig. 3 is the front bumper check apron that the utility model embodiment provides
Working state schematic representation；Fig. 4 is the sectional view in A-A directions in Fig. 3；Fig. 5 is the sectional view in B-B directions in Fig. 3.
As shown in Figures 1 to 5, the utility model embodiment provides a kind of front bumper check apron 1, is arranged at cab assembly
Between 4 and bumper assembly 6 (as shown in Figure 1), the forepart that entire vehicle is formed with cab assembly 4 and bumper assembly 6 is made
Type plays the role of beautifying moulding, while cabin interior is played and is blocked.Check apron 1 provided in this embodiment includes skeleton 2
With the elastomeric overmold part 3 to be linked together with the skeleton 2 by quadric injection mould, 2 top of skeleton with the driver's cabin
The position of assembly 4 and electrical harness interference is provided with notch section, and the skeleton 2 is by being formed in the mounting hole 13 of skeleton one end
And fixed on the bumper assembly 6, the outer edge 12 of the skeleton 2 is provided with cladding slot, and the elastomeric overmold part 3 passes through
The cladding slot is integrally covered in the external visible location of the skeleton.
Further, multiple bonding holes 11 are provided on the skeleton.Specifically, as shown in Fig. 2, in the front side of skeleton 2
Multiple bonding holes can be set with right side, elastomeric overmold part 3 can be penetrated into bonding hole, is bonded together with skeleton, ensure cladding
The bonding strength of part and skeleton.
Further, mounting hole 13 can protrude the front end for being formed in skeleton 2, can form 4 mounting holes in the front end of skeleton 2
13, as shown in Fig. 2, check apron 1 can be fixed on bumper assembly 6 by this 4 mounting holes.
In the utility model, notch section is used to ensure that the outer edge 12 of skeleton 2 will not be dry with the generation of cab assembly 4
It relates to.It is bonded hole and cladding slot is used for when carrying out quadric injection mould, can ensure the strength of connection of skeleton 2 and elastomeric overmold part 3, root
According to the decrement and compression stress that elastic coating member is subject in switching process, portion is locally thickeied and is thinned, ensure compression by
Power is uniform.
In one exemplary embodiment, front bumper check apron 1 is made of MODIFIED PP skeleton 2 and TPE covering quadric injection moulds；
MODIFIED PP material by EPDM modifications and adds 20% talcum powder composition, ball indentation hardness 25-35MPa for PP；TPE material is
Can with post forming can coated elastomer, shore a hardness be 70 ± 5 (HA), have excellent flex life and low hysteresis.
The decrement and compression stress that the TPE coverings are subject to according to covering in switching process, portion are locally thickeied and are thinned, and ensure pressure
Contracting uniform force, when driver's cabin is restored to normal condition, check apron can spring back to home position within the regular hour, -40
DEG C to all having good compression resilience under 80 DEG C of environment.In addition, in one example, decorative pattern is may be provided on TPE coverings,
So that visual experience sense is stronger.
In practical applications, the front bumper check apron 1 of the utility model is mounted on bumper assembly 6 by mounting hole 13
On, front bumper check apron 1 is at 21 position of TPE coverings original position, as shown in Figure 4.When repairing engine, cab assembly
