As shown in fig. 1 to 13, a floor panel 100 includes: a pedal body 20. As a specific embodiment, the pedal body 20 is formed by one-time die casting.

As a preferred embodiment, the pedal body 20 includes: a pedal body 22 and a pedal body reinforcing insert 21. The pedal body reinforcing insert 21 is embedded inside the pedal body 22. Specifically, the pedal body reinforcing insert 21 traverses the pedal body 22. More specifically, the pedal body reinforcing insert 21 traverses the pedal body 22 in the longitudinal direction, and has high strength in keeping integrity in the longitudinal direction. The number of the pedal body reinforcing inserts 21 is several. Several pedal body reinforcing inserts 21 are arranged side by side. Specifically, the number of the pedal body reinforcing inserts 21 is 3. As an alternative embodiment, the number of the pedal body reinforcing inserts may be set to 1, 2 or more as required.

In a preferred embodiment, the pedal body reinforcing insert 21 is formed with a plurality of pedal body reinforcing insert flow holes 211. The pedal body reinforcing insert flow holes 211 allow alloy fluid to flow through during die casting. The pedal body reinforcing insert flow hole 211 is a through hole. The pedal body 20 is an aluminum alloy die-cast product, and the alloy liquid is an aluminum alloy liquid. And the pedal body reinforcing insert 21 is a reinforcement made of a steel material. The pedal body reinforcing insert positioning structures are arranged at equal intervals. The pedal body reinforcing insert flow holes 211 are arranged at equal intervals. A plurality of pedal body reinforcing insert circulation holes 211 are formed between the two adjacent pedal body reinforcing insert positioning structures.

The high temperature aluminum alloy liquid in the mold passes through the pedal body reinforcing insert flow holes 211 to provide a mold flow channel for fast filling of the mold cavity. When cooling, because the alloy liquid has filled footboard main part and has strengthened inserts circulation hole 211, footboard main part body 22 passes footboard main part through footboard main part and strengthens inserts circulation hole 211 and strengthen inserts 21 after the shaping to make footboard main part body 22 and footboard main part strengthen inserts 21 and further connect into unified whole, reduce because the influence of the different cooling rate of material and shrinkage factor to product quality in the cooling process, the off-the-shelf qualification rate of very high yield product.

As a preferred embodiment, the pedal body reinforcing insert 21 is provided with a pedal body reinforcing insert locating structure for securing the pedal body reinforcing insert 21 within the mold.

As a specific embodiment, the number of the pedal body reinforcing insert positioning structures is multiple. The plurality of pedal body reinforcing insert positioning structures are arranged along the extending direction of the pedal body reinforcing insert 21. Specifically, the pedal body reinforcing insert positioning structure is a pedal body reinforcing insert positioning hole 212. The pedal body reinforcing insert 21 is defined at a designated position of the mold by the insertion of the bracket member into the pedal body reinforcing insert positioning hole 212. More specifically, the pedal body 20 further includes: the pedal body reinforces the insert positioning rod 221. The pedal body reinforcing insert locating bar 221 and the bracket member cooperate to define the pedal body reinforcing insert 21 in a designated location of the mold.

The pedal main body 22 is formed with a pedal main body fixing hole 222. The pedal body reinforcing insert positioning hole 212 is provided on one side of the pedal body reinforcing insert 21. The pedal body reinforcement insert positioning holes 212 are blind holes. The pedal body securing apertures 222 communicate with the pedal body reinforcement insert positioning apertures 212.

The pedal body reinforcing insert positioning rod 221, the pedal body reinforcing insert positioning hole 212, and the pedal body fixing hole 222 are arranged along a straight line. The pedal body reinforcing insert positioning rod 221 and the bracket member clamp the pedal body reinforcing insert 21 from both sides, helping to keep the pedal body reinforcing insert 21 fixed and prevent from being separated from the position by the impact of the mold flow. The pedal body reinforcing insert positioning bar 221 prevents the pedal body reinforcing insert 21 from moving toward the front surface of the pedal body 20 and ensures the thickness of the pedal body 20 at the front surface of the pedal body reinforcing insert 21. The material of the pedal body reinforcing insert positioning rod 221 is the same as that of the pedal body 22.

As an alternative embodiment, the pedal body reinforcing insert positioning structure may not be provided as a hole. For example, the pedal body reinforcing insert positioning structure is provided as a column body, and the column body is inserted into the bracket for positioning. The bracket is formed on the column body matched structure to strengthen the positioning of the insert for the pedal body. That is, the pedal body reinforcing insert positioning structure is a structure that can cooperate with the mold to define the pedal body reinforcing insert 21 at a specified position of the mold. The pedal body reinforcing insert positioning structure can be positioned at the upper end and the lower end of the pedal body reinforcing insert and also can be positioned at the left end and the right end of the pedal body reinforcing insert.

In a preferred embodiment, the depth direction of the pedal body reinforcing insert positioning hole 212, the depth direction of the pedal body reinforcing insert circulation hole 211, and the direction in which the pedal body reinforcing insert 21 penetrates the pedal body 22 are perpendicular to each other. The hole depth direction of the pallet body reinforcing insert positioning hole 212 is parallel to the thickness direction of the pallet body 20. The hole depth direction of the pedal body reinforcing insert flow holes 211 is perpendicular to the thickness direction of the pedal body 20. The hole depth direction of the pedal body reinforcing insert positioning hole 212 is perpendicular to the hole depth direction of the pedal body reinforcing insert flow hole 211. The arrangement of the pedal body reinforcing insert positioning hole 212 in the hole depth direction, the pedal body reinforcing insert circulation hole 211 in the hole depth direction and the pedal body reinforcing insert 21 in the direction penetrating through the pedal body 22 increases the position stability of the pedal body reinforcing insert 21, reduces the impact of mold flow on the pedal body reinforcing insert 21, and increases the strength of the pedal body 20 as much as possible.

In one embodiment, the front surface of the pedal body 22 is provided with an anti-slip structure. The back of the pedal main body 22 is provided with a reinforcing rib. The pedal body reinforcing insert 21 is in a strip shape and is wrapped in the reinforcing ribs. The reinforcing ribs form the pedal body fixing holes 222. After the product is formed, whether the pedal body fixing hole 222 is filled or not can be considered as required.

In the direction in which the pedal body reinforcing insert 21 penetrates the pedal body 22, both ends of the pedal body reinforcing insert 21 are exposed from both ends of the pedal body 22. Both ends of the pedal body reinforcing insert 21 in the longitudinal direction are exposed from the pedal body 22. The exposed portion may be cut or not cut as desired.

As a preferred embodiment, the floor panel 100 further comprises: the comb support plate 10.

The comb support plate 10 is formed by one-time die casting. The comb support plate 10 is mounted with a comb structure. That is, the comb tooth structure is independent of the comb tooth support plate, and the comb tooth structure can also be called as a comb plate at the moment. It may be a direct mounting, i.e. the comb structure is directly fixed to the comb support plate. Or indirectly, e.g. the comb structure is mounted to the comb support plate via an intermediate part, i.e. the comb support structure. The comb tooth support structure can realize the same installation of the comb tooth structure. The installation mode is adopted, different comb tooth structures can be conveniently adapted according to needs, the maintenance and the replacement of the comb tooth structures are facilitated, and only partial structures need to be replaced without replacing the whole structure when the maintenance is replaced.

As an alternative embodiment, the comb tooth structure is formed by a comb tooth support plate, i.e. the comb tooth structure is formed as a part of the comb tooth support plate. The number of parts is reduced, the assembly process is reduced, and the production efficiency is accelerated.

The comb support plate 10 is connected to the pedal body 20. The comb support plate 10 is connected to one end of the pedal body 20. The comb tooth structure is provided at the other end of the comb tooth support plate 10. The comb support plate 10 and the pedal body 20 may be coupled in an overlapping manner. The end of the comb support plate may be placed above the end of the pedal body, or the end of the pedal body may be placed above the end of the comb support plate. The convex block can be arranged at the lapping position of the comb tooth support plate and the pedal main body to increase the lapping length and improve the reliability. Specifically, a bump is added to the lower of the two overlapping parts. For example, the end of the pedal body is lapped above the end of the comb tooth support plate, i.e., the end of the comb tooth support plate is located below, and a projection is added to the end of the comb tooth support plate. Specifically, the number of bumps is 3.

The end of the pedal body 20 remote from the comb support plate 10 may be overlapped to increase the length as needed. As an alternative embodiment, the overlapping section of increased length may also be integrally formed as part of the pedal body.

As a preferred embodiment, the comb support plate 10 includes: the comb support plate body 12 and the comb support plate reinforcing insert 11. The comb support plate reinforcing inserts 11 are embedded in the comb support plate body 12. A comb support plate reinforcing insert 11 traverses the comb support plate body 12. Specifically, the comb support plate reinforcing inserts 11 traverse the comb support plate body 12 in the longitudinal direction, which is an integral structure that helps maintain high strength.

The comb support plate body 12 and the pedal main body 22 are made of aluminum alloy in the same material. The materials of the comb supporting plate reinforcing insert 11 and the pedal main body reinforcing insert 21 are the same and are steel pieces. Specifically, the comb support plate reinforcing insert 11 and the pedal body reinforcing insert 21 are high-strength structural steel.

As a preferred embodiment, the comb support plate reinforcing insert 11 is provided with a comb support plate reinforcing insert positioning structure for fixing the comb support plate reinforcing insert 11 in the mold. The positioning structure of the comb tooth supporting plate reinforcing insert is a hole. Which may also be referred to as comb support plate, reinforces insert locating holes 111. The comb support plate reinforcing insert positioning hole 111 is used for fixing the comb support plate reinforcing insert 11 in the mold. The comb support plate reinforcing insert positioning hole 111 is a through hole. The comb-support-plate reinforcing inserts 11 may be defined at the designated positions of the die by inserting the bracket members into the comb-support-plate reinforcing insert positioning holes 111 in the same positioning manner as the pedal-body reinforcing inserts 21. The comb support plate 10 further includes: the insert locating bar 121 is reinforced by the comb support plate. The comb-support-plate reinforcing-insert positioning rod 121 and the bracket member together define the comb-support-plate reinforcing insert 11 at a designated position of the mold.

The comb support plate body 12 forms comb support plate body fixing holes 122. The comb support plate reinforcing insert positioning rod 121 and the comb support plate body fixing hole 122 are located on both sides of the comb support plate reinforcing insert 11. The center of the comb support plate reinforcing insert positioning hole 111 passes through the comb support plate body fixing hole 122. The comb support plate reinforcing insert positioning hole 111 and the comb support plate body fixing hole 122 are aligned, and two holes are penetrated by one support. The comb support plate reinforcing insert positioning rod 121 is disposed in a manner not aligned with the comb support plate body fixing hole 122. The comb support plate reinforcing insert 11 is of a plate-like structure. The comb support plate reinforcing insert positioning hole 111 is a through hole. The bracket can penetrate through the comb tooth supporting plate to reinforce the insert positioning hole 111 and is exposed out to increase stability. The comb support plate reinforcing insert positioning rod 121 prevents the comb support plate reinforcing insert 11 from moving to the front of the comb support plate 10 and ensures the thickness of the comb support plate 10 in the front of the comb support plate reinforcing insert 11. The material of the comb support plate reinforcing insert positioning rod 121 is the same as that of the comb support plate body 12.

In a preferred embodiment, the comb support plate reinforcing insert 11 is provided with comb support plate reinforcing insert flow holes 112 that allow the alloy liquid to flow through during the die casting process. The comb tooth support plate reinforcing insert flow holes 112 are through holes. The high temperature aluminum alloy liquid in the mold passes through the comb supporting plate reinforcing insert flow holes 112 to provide a mold flow passage for fast filling of the mold cavity. When cooling, because the broach backup pad has been filled to the alloy liquid and has strengthened inserts circulation hole 112, shaping back broach backup pad body 12 passes broach backup pad through broach backup pad and strengthens inserts circulation hole 112 and strengthen inserts 11 to make broach backup pad body 12 and broach backup pad strengthen inserts 11 and further connect into unified whole, reduce in the cooling process because the influence of the different cooling rate of material and shrinkage factor to product quality, the off-the-shelf qualification rate of very high yield product.

In a preferred embodiment, the comb-support-plate reinforcing insert 11 has a bent plate-like structure, and further increases the strength, so that the strength can be satisfied with a small thickness. The structural arrangement of the comb support plate reinforcing insert 11 can reduce or adapt to the thinner comb support plate 10. The comb support plate reinforcing insert positioning holes 111 and the comb support plate reinforcing insert circulation holes 112 penetrate the comb support plate reinforcing inserts 11 in the thickness direction of the plate-like structure. Specifically, the comb-support-plate reinforcing insert positioning holes 111 and the comb-support-plate reinforcing insert circulation holes 112 are parallel to each other in the hole depth direction.

The comb support plate reinforcing inserts 11 are partially exposed on at least one of both sides of the comb support plate body 12 in the thickness direction of the comb support plate 10. Alternatively, the comb support plate reinforcing inserts 11 are partially exposed on at least one of the front and back surfaces of the comb support plate 10. Specifically, the comb support plate reinforcing insert 11 is partially exposed at the back of the comb support plate 10. More specifically, one end portion of the comb support plate reinforcing insert 11, which is formed near the comb support plate 10 or to which the comb structure is mounted, is exposed to the back surface of the comb support plate 10. The intensity of broach structure mounted position department has been increased promptly, has still avoided both sides parcel broach backup pad 10 to cause the aluminum alloy thickness of both sides thinner, the unstable problem of product quality. The two ends of the comb tooth supporting plate reinforcing insert 11 are partially exposed on the back and the front of the comb tooth supporting plate 10, and the mold core is conveniently utilized to position the comb tooth supporting plate reinforcing insert 11.

As an alternative embodiment, the comb support plate reinforcing insert may be provided in the same structure as the pedal body reinforcing insert 21. The mounting and positioning means can also be provided in exactly the same manner as the pedal body reinforcing insert 21.
