Description
Technical Field
The utility model relates to a case and bag field technique, concretely relates to back of body pad and knapsack.
Background
With the ever-increasing standard of life and consumption of people, various backpacks become indispensable articles for daily use of people. The human back bears pressure when the knapsack is used, and the phenomenon of humpback is easily caused after long-time use, therefore, the back of the knapsack body is mostly provided with a back cushion in the prior knapsack, and the back cushion provides a buffer effect to protect the human back. However, the existing back cushion is generally only a flat cushion block with good flexibility, the most important structure of the back of a human body, which is most easily affected by the pressure of the backpack, is a spine, and the existing back cushion cannot be perfectly attached to the spine of the back of the human body, so that the existing back cushion has poor protection effect on the back of the human body.
Chinese patent application No. CN201520143111.8, application No. 2015.03.13 discloses a back pad and a backpack using the same. This knapsack is including the back of the body of filling up, and this back of the body of filling up is EVA elasticity expanded material, and the back of the body of filling up is including basic unit portion, spine portion, protruding portion and two gasket portions to and, the periphery of this back of the body of filling up is provided with the meshbelt, and the surface covering of the back of the body of filling up has single-layer screen cloth or lycra cloth. The sense of this product when the arch can let the user knapsack is enlarged, in time adjusts braces, knapsack position etc. protruding shape design can laminate user back when the knapsack, and is comfortable and alleviate and bears the burden, and gasket portion can adapt to crooked in order to paste tight user back muscle better, when laminating comfortable, the muscle burden of releiving as far as possible to can follow great scope and crooked adaptation user.
However, the two pad portions of the back pad tend to be higher at the middle and lower at the outer side from the middle toward the outer side. Therefore, the height of the bulges at the middle parts of the two gasket parts is higher than that of the bulges at the outer parts of the two gasket parts, when a user carries the backpack, the pressure of the outer parts of the two gasket parts on the back of the user is higher than that of the middle parts of the two gasket parts on the back of the user, the pressure of the back pad on the back of the human body is uneven, and the user feels uncomfortable after long-term use.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-6, a backpack comprises a back pad 1 disposed on the back surface of the backpack, the back pad 1 comprises a protection pad 2, a strap adjusting part 3 and a reinforcing part 4, the protection pad 2 is formed on the surface of the back pad 1 in an upward protruding manner, a buffer space is formed between the protection pad and the back pad, the buffer space is a hollow space, and an elastic material such as sponge can be filled in the buffer space, in this embodiment, the buffer space is a hollow space,
the protection pad 2 comprises a first protection pad 21 and a second protection pad 22; the number of the first protection pads 21 is more than two, the first protection pads 21 are symmetrically arranged on the left side and the right side of the back cushion 1 and are obliquely arranged from the middle of the back cushion 1 to the two sides of the back cushion 1; the second protection pad 22 is disposed at the middle of the back pad 1 and below the first protection pad 21.
The first protection pad 21 is inclined from the upper end to the lower end of the back pad 1. This allows the force of the upper end of the back pad 1 to better act on the user's back. The height of the highest point of the first protection pad extension 211 on the same side of the back pad 1 increases from the upper end of the back pad 1 to the lower end thereof. Due to the physiological curvature of the upper end and the lower end of the back of the human body, the back cushion can be better attached to the back of a user.
The first protection pad 21 includes a first protection pad extension portion 211 and a first protection pad top surface 212 surrounded by the first protection pad extension portion 211, and a connection portion between the first protection pad extension portion 211 and the first protection pad top surface 212 is in arc transition connection. The adoption of the arc transition connection can increase the beauty of the protection pad 2 on one hand, and can prevent the scratching phenomenon of a user caused by the sharp corner at the joint between the extension part and the top surface of the protection pad 2 on the other hand.
The top surface 212 of the first protection pad is inclined downwards from one side far away from the middle part of the back pad 1 to one side close to the middle part of the back pad 1; a first ventilation groove 23 is formed between the adjacent first protection pad extension parts 211; the second protection pad 22 includes a second protection pad extension part 221 and a second protection pad top surface 222 surrounded by the second protection pad extension part 221, the second protection pad top surface 222 includes a second protection pad top surface 2221 close to the first protection pad 21 and a second protection pad top surface 2222 at the lower end of the back pad 1, and the second protection pad top surface 2221 is inclined downward from the side far away from the middle of the back pad 1 to the side close to the middle of the back pad 1; the second protection pad top surface 2222 is inclined downward from a side far from the lower end of the back pad 1 to a side close to the lower end of the back pad 1. A second ventilation groove 24 is formed between the second protection pad extension part 221 and the first protection pad extension part 211.
Because the back of the human body is not a plane, the human body has certain physiological curvature. First protection pad 21 symmetry sets up at back of the body pad 1 both sides, second protection pad 22 sets up at back of the body pad 1 middle part and is located the lower extreme of first protection pad 21, and first protection pad 21 and second protection pad 22 are close to the top surface of first protection pad 21 and set up to the inboard side direction slope from the outside, make the outside of first protection pad 21 and second protection pad 22 form one and use back of the body pad 1 middle part as the accommodation space at center, thereby first protection pad 21 and second protection pad 22 outside laminate with the user better, user's back bending can enter into the accommodation space more effectively, make back of the body pad 1 upper force can be more direct and act on one's body at the user effectively, it is effectual to make user back atress, it is comfortable to use. The first ventilative groove 24 that ventilates with the second of shaping on the back pad 1 strengthens the gas permeability of back pad 1, lets user's back can contact with the air of circulation, improves the comfort of using. By arranging the lower end portion of the second protection pad 22 to be inclined toward the lower end of the back pad 1, the lower end of the back pad 1 is more effectively contacted with the waist of the user, partial force of the lower portion of the back pad 1 can be effectively applied to the waist of the user, and the stress effect is further improved.
The strap adjusting part 3 is arranged between the first protection pads 21 at the left and right ends of the back cushion 1, and the strap adjusting part 3 can change the position and height of the straps on the back cushion and is suitable for users of different ages. The strap adjusting part 3 comprises a plurality of adjusting parts with different heights, the straps are connected around the adjusting parts, when the height position of the straps needs to be adjusted, the straps are detached from the current adjusting parts, and then the straps are connected around the adjusting parts with other heights. A reinforcement portion 4 provided between the first protection pad 21 and the strap adjusting portion 3. Reinforcing part 4 is for covering the both ends of regulating part and with back of the body pad fixed connection's part, and reinforcing part 4 is connected with the back of the body pad through the mode of sewing, and the atress effect of braces regulating part can be strengthened to the reinforcing part, extension back of the body pad life.
