Technical Field

[0001] This utility model relates to the field of schoolbag technology, and more specifically, it relates to a cushioning and shock-absorbing device for bearing the weight at the bottom of a schoolbag. Background Technology

[0002] Backpacks are primarily used for storing and carrying school supplies. A backpack typically has a main compartment for storing and carrying books and textbooks, as well as several small pockets for storing pencils, notebooks, erasers, and other stationery items for students to use at any time. It also usually has a double shoulder strap system to distribute the weight between the student's sides, reducing strain on the back and shoulders.

[0003] Currently, backpacks become very heavy when filled with a large number of books. When students walk or run for extended periods while carrying these backpacks, the books sway inside, affecting their balance. Furthermore, the backpack constantly bumps against the student's back, causing back pain and inconvenience. In summer, the backpack's close contact with the back causes excessive sweating, making the backpack wet. Therefore, we have designed a cushioning and shock-absorbing device for the bottom of the backpack to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cushioning and shock-absorbing device for the bottom of a schoolbag. By setting up the cushioning and shock-absorbing component, it can provide support and cushioning. The cushioning and shock-absorbing component can also be removed from the schoolbag body for easy cleaning of the inside of the schoolbag. The cushioning pad can reduce the impact of the schoolbag body on the student's back during activities, and it can also promote air circulation, reducing the stuffiness caused by excessive sweating on the back in summer and the phenomenon of the schoolbag getting wet.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a cushioning and shock-absorbing device for bearing the weight of the bottom of a schoolbag. It includes a schoolbag body with a storage cavity for placing books inside. A cushioning and shock-absorbing component is placed at the bottom of the storage cavity. The outer wall of the cushioning and shock-absorbing component is covered with an anti-slip layer that abuts against the inner wall of the storage cavity. A support vertical plate is fixedly connected to one side of the upper end of the anti-slip layer, and a strap is fixedly connected to the other side of the upper end of the anti-slip layer. The strap and the support vertical plate are connected by multiple snaps arranged at equal intervals. The schoolbag body is provided with a shoulder strap, and multiple cushioning pads are installed on the side of the schoolbag body near the shoulder strap.

[0007] As a preferred embodiment of this utility model, the buffer and shock absorption assembly includes an upper plate and a lower plate, with a buffer column connecting the upper plate and the lower plate. The anti-slip layer is wrapped around the outer side of the upper plate and the lower plate, and the anti-slip layer is fixedly connected to the upper surface of the upper plate and the lower surface of the lower plate.

[0008] As a preferred technical solution of this utility model, the buffer column includes a buffer sleeve fixedly connected to the bottom of the lower plate, a sliding plate slidably connected inside the buffer sleeve and abutting against its inner side wall, a sliding column fixedly connected to the upper end of the sliding plate, the sliding column slidingly penetrating the upper side wall of the buffer sleeve and extending above it, and a plurality of springs connecting the sliding plate and the inner bottom of the buffer sleeve.

[0009] As a preferred embodiment of this utility model, the snap fastener includes a male snap fastener fixedly installed on the side wall of the strap, and a female snap fastener is fixedly installed on the side wall of the supporting vertical plate, wherein the male snap fastener and the female snap fastener are compatible.

[0010] As a preferred embodiment of this utility model, the upper plate, lower plate and supporting vertical plate are all made of plastic.

[0011] As a preferred embodiment of this utility model, the cushioning pad is composed of an air bladder and a breathable mesh fabric, with the breathable mesh fabric wrapped around the outside of the air bladder.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, by placing the book between the strap and the supporting vertical plate, can restrict the book, thereby reducing the shaking of the book when the student is active. When the upper plate is subjected to the vertical force of the book, the buffer column can play a role in buffering and shock absorption. Thus, the buffer and shock absorption component can play a supporting and buffering role. In addition, the buffer and shock absorption component can be removed from the backpack body, which is convenient for cleaning the inside of the backpack body.

[0014] 2. By setting up a cushioning pad, this utility model can reduce the impact of the backpack body on the student's back during activities. The small contact area between the cushioning pad and the human body allows for a gap between the backpack body and the student's back, which is conducive to air circulation, does not affect the body's perspiration, and reduces the phenomenon of excessive sweating on the back in summer, which can easily cause stuffiness and make the backpack wet.

[0025] Please see Figures 1-6 Structural diagram; the present invention provides the following technical solution:

[0026] Specifically, it refers to a cushioning and shock-absorbing device for the bottom load-bearing of a schoolbag, including a schoolbag body 1, which is opened and closed by a zipper. The schoolbag body 1 has a storage cavity 2 for placing books inside. A cushioning and shock-absorbing component is placed at the bottom of the storage cavity 2. The outer wall of the cushioning and shock-absorbing component is covered with an anti-slip layer 6 that abuts against the inner wall of the storage cavity 2. The cushioning and shock-absorbing component includes an upper plate 3 and a lower plate 4. A buffer post 5 is connected between the upper plate 3 and the lower plate 4. The buffer post 5 can play a cushioning and shock-absorbing role. The anti-slip layer 6 is wrapped around the outer side of the upper plate 3 and the lower plate 4. The anti-slip layer 6 can play a protective role for the upper plate 3 and the lower plate 4, and can increase the friction between the upper plate 3 and the inner wall of the storage cavity 2 inside the schoolbag body 1. Thus, the cushioning and shock-absorbing component can be stably placed at the bottom of the storage cavity 2, and can be taken out by pulling it outward.

[0027] The buffer column 5 includes a buffer sleeve 501 fixedly connected to the bottom of the lower plate 4. A sliding plate 502 is slidably connected inside the buffer sleeve 501 and abuts against its inner side wall. The sliding plate 502 abuts against the inner side wall of the buffer sleeve 501, so that the sliding plate 502 can generate a large friction force between the sliding plate 502 and the buffer sleeve 501. A sliding column 503 is fixedly connected to the upper end of the sliding plate 502. The sliding column 503 slides through the upper side wall of the buffer sleeve 501 and extends above it. Multiple springs 504 are connected between the sliding plate 502 and the inner bottom of the buffer sleeve 501. When the student runs and the upper plate 3 is subjected to the force of the book, the springs 504 can play a buffering and shock-absorbing role. The sliding plate 502 slides inside the buffer sleeve 501, and the energy of the springs 504 is consumed by friction, reducing the phenomenon of repeated rebound.

[0028] A support vertical plate 8 is fixedly connected to one side of the upper end of the anti-slip layer 6. The support vertical plate 8 fits against the inner wall of the placement cavity 2. The upper plate 3, lower plate 4, and support vertical plate 8 are all made of plastic, which can provide support. The plastic material is lightweight, which can reduce the overall weight of the backpack body 1 to a certain extent, making it suitable for students to carry daily. At the same time, it has good flexibility, can be bent to a certain extent, and is not easy to break. A strap 7 is fixedly connected to the other side of the upper end of the anti-slip layer 6. The strap 7 is connected to the support vertical plate 8 by multiple equally spaced snaps 9. The book is placed in the placement cavity 2 and located between the strap 7 and the support vertical plate 8. According to the height of the book, the strap 7 and the support vertical plate 8 are connected by snaps 9 that are adapted to the height of the book. This can encircle the book between the strap 7 and the support vertical plate 8, which helps to fix the book and reduce the impact of the book shaking when the student runs. The snaps 9 include a male snap 901 fixedly installed on the side wall of the strap 7 and a female snap 902 fixedly installed on the side wall of the support vertical plate 8. The male snap 901 and the female snap 902 are adapted to each other and can fasten the strap 7 and the support vertical plate 8 tightly.

[0029] The backpack body 1 is equipped with shoulder straps. Multiple cushioning pads 10 are installed on the side of the backpack body 1 near the shoulder straps. The cushioning pads 10 are composed of air bladders and breathable mesh fabric. The breathable mesh fabric is wrapped around the outside of the air bladders. The cushioning pads 10 are hemispherical. The cushioning pads 10 can reduce the impact of the backpack body 1 on the student's back when the student is active. The breathable mesh fabric can ensure breathability. The cushioning pads 10 can also create a gap between the backpack body 1 and the student's back. The cushioning pads 10 have a small contact area with the human body, which is conducive to air circulation and does not affect the body's perspiration. This reduces the phenomenon of stuffiness caused by excessive sweating on the back in summer and the easy wetting of the backpack.

[0030] The working principle of the cushioning and shock absorption device for supporting the bottom of a schoolbag provided by this utility model is as follows:

[0031] Working principle: A cushioning and shock-absorbing device for the bottom of a schoolbag. In use, the book is placed in the placement cavity 2 between the strap 7 and the support vertical plate 8. According to the height of the book, the strap 7 and the support vertical plate 8 are connected by snaps 9 that are adapted to the height of the book. This can encircle the book between the strap 7 and the support vertical plate 8, which can restrict the book and reduce the shaking of the book. When students are active, it can reduce the impact of the book shaking on the students when they run. When the upper plate 3 is subjected to the vertical force of the book, the spring 504 can play a cushioning and shock-absorbing role. The sliding plate 502 slides in the cushioning sleeve 501, and the energy of the spring 504 is consumed by friction, reducing the phenomenon of repeated rebound. Thus, the cushioning and shock-absorbing component can play a supporting and cushioning and shock-absorbing role.

[0032] The cushioning pad 10 is hemispherical, which can reduce the impact of the backpack body 1 on the student's back during activities. The cushioning pad 10 also creates a gap between the backpack body 1 and the student's back. The cushioning pad 10 has a small contact area with the human body, which is conducive to air circulation and does not affect the body's perspiration. This reduces the stuffiness caused by excessive sweating on the back in summer and the phenomenon of the backpack getting wet easily.

[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
