Description

EPS packaging box for gearbox

Technical Field

The invention belongs to the technical field of packaging boxes, and in particular relates to an EPS packaging box for a gearbox.

Background technique

With the advancement of automobile technology and the improvement of people's consumption level, cars have entered the homes of ordinary people. Especially in recent years, the number of vehicles in my country has increased year by year, and many cars have benefited from this.

For car companies, more and more car companies have built different departments in different regions in order to reduce costs. For example, R&D departments are often set up in economically developed regions, while production workshops are set up in regions with cheap labor. For cars, they contain many parts, among which the more important ones are powertrains such as engines and gearboxes. In the prior art, due to the large weight of the gearbox, which is usually between 70 and 80 kg, and even more than 80 kg, the gearbox packaging box uses a wooden box with a foam lining. The disadvantages of this method are: a large amount of wood boards are used, nails and tools are required during the installation process, resulting in high labor intensity and high packaging costs; the weight of the wood boards is relatively high, resulting in high logistics costs; the foam lining only contacts several important parts of the outer surface of the transmission, and cannot play a comprehensive protective role, and there is no connection between the foam liners, resulting in the internal fixation being easy to loosen; the packaging box can only accommodate one transmission, and the storage rate is relatively low.

In summary, there are some areas in which the packaging methods in the prior art need to be improved during the entire logistics and transportation process.

Summary of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art and to provide an EPS packaging box for a gearbox, which can accommodate multiple gearboxes and can achieve more comprehensive fixation by making more contact with the surface of the gearbox.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

As shown in Figures 1 and 2, an EPS packaging box for a gearbox includes an upper box body 1 and a lower box body 11. When in use, the lower box body 11 is placed on the ground, and the upper box body 1 is buckled on the lower box body 11 to form a complete packaging box, so the lower box body 11 mainly plays a supporting role.

The upper case 1 has a plurality of cavities 2 formed by being recessed inward from its connection end surface. The cavities 2 are centrally symmetrically distributed in the first direction and arranged at equal intervals in the second direction. The two cavities 2 located in the first direction are separated by a longitudinal partition 6, and the two cavities 2 located in the second direction are separated by a transverse partition 17. The lower case 11 has a plurality of cavities 20 formed by being recessed inward from its connection end surface. The cavities 20 are centrally symmetrically distributed in the first direction and arranged at equal intervals in the second direction. The two cavities 20 located in the first direction are separated by a longitudinal partition 12, and the two cavities 20 located in the second direction are separated by a transverse partition 18. As a typical arrangement, there are 2 cavities 2 in the first direction and 3 cavities in the second direction, forming a 2×3 distribution. Similarly, there are 2 cavities 20 in the first direction and 3 cavities in the second direction, forming a 2×3 distribution. When the upper case 1 and the lower case 11 are buckled together, a total of 6 completed cavities are formed, which can accommodate 6 gearboxes. Since the first cavity 22 and the second cavity 20 in the first direction are centrally symmetrically distributed, the center of gravity of the entire packaging box can be located in the center, which is convenient for loading and unloading.

The lower box body 11 is also provided with a plurality of reinforcing members corresponding to each cavity 20. According to actual needs, the reinforcing members are PP boards, wooden boards, PP special-shaped members or wooden special-shaped members that are compatible with the stress-bearing parts at the bottom of the gearbox. The reinforcing members are arranged inside the lower box body in the form of embedded parts during injection molding, thereby greatly improving the support and pressure resistance.

A plurality of connection slots 3 are distributed on the connection end surface of the upper box 1 and the connection end surface of the lower box 11. The connection slots 3 can be inserted with reinforcement blocks to make the upper box 1 and the lower box 11 plugged into one. As a typical implementation, the connection slots 3 are arranged at the four corners of the connection end surface of the upper box 1 and at the connection between the side wall of the upper box 1 and the transverse partition; the reinforcement blocks are PP blocks or wooden blocks, which can play a good role in positioning, connection and fixing. The first direction is the width direction of the packaging box, and the second direction is its length direction.

After the upper box body 1 and the lower box body 11 are plugged together, the first cavity 22 and the corresponding second cavity 20 can completely accommodate the gearbox.

The bottom wall of cavity 1 2 is parallel to the connecting end face of the upper box body 1, corresponding to the larger plane on the gearbox; the bottom wall of cavity 2 20 has at least a stepped structure that gradually increases from right to left along the first direction, corresponding to the stepped surface on the other side of the gearbox.

A protrusion 4 is provided in the cavity 12, and the protrusion 4 is connected to the front wall and the bottom wall of the cavity 12, and the protrusion 4 can be matched with a recess 1 on the front side of the gearbox.

The bottom wall of the cavity 1 2 has a protrusion 10 protruding upward and a gas avoidance groove 5 recessed downward, and the protrusion 10 has a curved surface that can be matched with the curved recess on the top of the gearbox; the gas avoidance groove 5 is a rectangular structure, and the part of the top of the gearbox that cannot be subjected to pressure can be avoided through the gas avoidance groove 5 to avoid damage.

A weight-reducing groove 9 is provided on the longitudinal partition 6, and a weight-reducing groove 28 is provided on the transverse partition 17; the weight-reducing groove 9 is close to the connection between the longitudinal partition 6 and the transverse partition 17, and the weight-reducing groove 28 is distributed to both sides from the connection between the longitudinal partition 6 and the transverse partition 17. As a typical structure, the cross-sectional shape of the weight-reducing groove 9 is a triangle, and the cross-sectional shape of the weight-reducing groove 28 is a rectangle or a polygon combining a rectangle and a triangle.

The longitudinal partition 1 6 and the longitudinal partition 2 12 are respectively inclined relative to the transverse partition 1 17 and the transverse partition 2 18. The ends of the longitudinal partition 1 6 and the longitudinal partition 2 12 are thickened to improve the connection strength.

The mold cavity 20 has a protrusion 3 16 and a protrusion 4 13 both extending along the first direction. The protrusion 3 16 is connected to the rear wall and the bottom wall of the mold cavity 20. The protrusion 3 16 can be adapted to the second recess on the front side of the gearbox. The two ends of the protrusion 4 13 form a gap with the left and right side walls of the mold cavity 20.

The second cavity 20 has a positioning block 14 protruding inward, and the positioning block 14 is connected to the bottom and right wall of the second cavity 20. The top surface of the positioning block 14 is higher than the connecting end surface of the second cavity 20, thereby forming a positioning side surface 15 close to the second longitudinal partition 12. The positioning side surface 15 can contact the side surface of the corresponding longitudinal partition 16 of the upper box body 1. The left wall of the first cavity 22 has a positioning groove 17 extending along the third direction, and the left wall of the second cavity 20 has a positioning groove 19 extending along the third direction; the third direction is the height direction. The cross-sectional shape of the positioning groove 17 and the positioning groove 19 is semicircular.

In the present invention, since the upper box body 1 and the lower box body 11 are used in a buckled manner, the left side of the upper box body 1 corresponds to the right side of the lower box body 11 .

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
