Technical Field

[0001] The present invention relates to the technical field of household items, and particularly relates to a lunch break mat. Background Art

[0002] A lunch break mat is a mat used for laying on the ground for taking a lunch break or a short nap, which can relieve fatigue and improve mental state, thereby improving the efficiency of work and study. For people engaged in mental work and primary and middle school students, taking a nap is more worthy of promotion.

[0003] Existing lunch break mats are usually folding lunch break mats, which are unfolded and laid on the ground during the lunch break and folded and stored after the lunch break. Some folding lunch break mats with a headrest function also have a headrest pad with a width of 20-30 cm at one end, which can be used as a headrest after being flipped when needed.

[0004] However, during the use of a folding lunch break mat with a headrest function, the surface of the headrest pad for the user's head to lean on is laid on the ground when the headrest pad is not in use, resulting in the surface of the headrest pad for the user's head to lean on being relatively dirty. For some users who pay attention to personal hygiene, it will affect the normal use of the headrest function. Summary of the Invention

[0005] The purpose of the present invention is to provide a lunch break mat with the function of preventing the surface of the headrest for the user's head from getting dirty.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A lunch break mat includes three connected and foldable first pads, a second pad connected to the first pads, and a headrest pad connected to the second pad. A light-shielding mechanism for achieving light shielding after unfolding is provided on the second pad. The light-shielding mechanism includes two mounting seats arranged on both sides of the second pad, a first support rod in a "U" shape arranged between the two mounting seats, a cushion cloth arranged in the first support rod and under the headrest pad, a second support rod in a "U" shape rotatably connected between the two mounting seats, a plurality of intermediate support rods in a "U" shape rotatably connected to the mounting seats, and a light-shielding cloth. The light-shielding cloth is arranged between the first support rod, the plurality of intermediate support rods and the second support rod; One end of the cushion cloth close to the second pad is connected to the second pad; The headrest pad is flipped and supported on the second pad to achieve the headrest function, and the second support rod and the plurality of intermediate support rods of the light-shielding mechanism drive the light-shielding cloth to unfold to achieve the light-shielding function.

[0007] By adopting the above technical scheme, firstly, the padding cloth of the shading mechanism can prevent the headrest pad from directly contacting the ground during use, thereby preventing the surface of the headrest pad for the user's head to lean on from getting dirty, and the shading cloth of the shading mechanism can be opened after the second support rod and multiple middle support rods are rotated to realize the shading function; in addition, for female users with long hair, their heads are surrounded by the shading mechanism, thereby preventing their hair from being scattered on the ground; at the same time, the shading mechanism is located within the range of the padding cloth, and some mobile phones and other items used before going to bed can be temporarily placed for temporary storage, which are not easy to be lost; ultimately, the headrest pad is prevented from getting dirty, a shading lunch break environment is provided for the user, the user's hair is prevented from getting dirty, and some items can be temporarily stored.

[0008] The present invention is further configured as follows: when the shading cloth of the shading mechanism is fully unfolded, the upper end of the second support rod extends upwardly and obliquely toward the direction close to the first cushion body, and a fixing structure is provided between the headrest pad and the shading mechanism for fixing the shading cloth in the shading function when the headrest pad is in the headrest function.

[0009] By adopting the above technical solution, when the shading cloth of the shading mechanism is fully unfolded, the upper end of the second support rod extends upwardly in an inclined direction close to the first cushion body. At this time, under the action of gravity on the second support rod, the shading cloth tends to remain in the unfolded state; at the same time, in conjunction with the fixed structure provided between the headrest pad and the shading mechanism, it is further ensured that the shading cloth remains in the unfolded state, thereby avoiding the shading mechanism from closing when it is accidentally touched.

[0010] The present invention is further configured as follows: the fixing structure includes a limiting portion integrally arranged on both sides of the headrest pad and having a limiting groove, and a limiting sleeve arranged at both ends of the second support rod and embedded in the limiting groove; when the limiting sleeve of the second support rod is embedded in the limiting groove, the limiting portion is squeezed and deformed.

[0011] By adopting the above technical solution, by arranging a limiting part with a limiting groove on both sides of the headrest pad, and arranging limiting grooves at both ends of the second support rod, when the second support rod is rotated into place, the limiting part will first be squeezed and deformed, and then when the limiting sleeve is embedded in the limiting groove of the limiting part, the second support rod of the shading mechanism is fixed, thereby realizing the fixation of the shading cloth with shading function.

[0012] The present invention is further configured as follows: when the headrest pad and the second support rod of the shading mechanism are in an initial state, the second support rod is located below the limiting portion; the operation steps of using the headrest pad and the shading mechanism are as follows: (S1) when the plurality of first pad bodies, the second pad bodies and the headrest pad are unfolded and laid flat on the ground, firstly, the second support rod of the shading mechanism is held and rotated, during which the second support rod applies an upward force to the limiting portion so that the headrest pad rotates upward, and the headrest pad automatically turns over under the action of gravity after turning over more than 90 degrees to realize the headrest function; (2) when the headrest pad has realized the headrest function and the second support rod is about to turn to the limit state, pressure is applied to both sides of the headrest pad toward the middle so that the headrest pad is deformed, thereby causing the second support rod to turn to the limit state, and then when the headrest pad recovers its deformation, the limiting sleeve of the second support rod is embedded in the limiting groove of the limiting portion of the headrest pad for fixation.

At this time, during the unfolding process of the shading mechanism, the headrest pad can be driven to flip and enter the headrest function. The operation steps are as follows: (S1) When the plurality of first cushion bodies, the second cushion bodies and the headrest pad are unfolded and laid flat on the ground, the second support rod of the shading mechanism is first held and rotated. During this process, the second support rod applies an upward force to the limiting part to make the headrest pad rotate upward, and the headrest pad automatically flips under the action of gravity after flipping more than 90 degrees to achieve the headrest function; (2) When the headrest pad has achieved the headrest function and the second support rod is about to rotate to the limit state, pressure is applied to both sides of the headrest pad toward the middle to make the headrest pad deform, so that the second support rod rotates to the limit state, and then when the headrest pad recovers its deformation, the limiting sleeve of the second support rod is embedded in the limiting groove of the limiting part of the headrest pad to be fixed.

[0014] The present invention is further configured as follows: connecting sleeves with plug-in slots are provided on both sides of the second pad body, the opening of the plug-in slots faces the side close to the first pad body, the mounting seat is laterally plugged into the plug-in slots of the connecting sleeves, and a zipper is provided between the pad cloth and the second pad body to achieve a detachable connection.

[0015] By adopting the above technical solution, the mounting seat is plugged into the plug-in slot of the connecting sleeve, and the opening of the plug-in slot faces the side close to the first pad body. The pad cloth and the second pad body are detachably connected by a zipper, so that the shading mechanism can be stably installed and fixed. In addition, when the zipper connection is cancelled and the connecting sleeve and the mounting seat are plugged in, the shading mechanism can be disassembled, which has the function of selecting whether to install according to actual needs and facilitating disassembly and cleaning.

[0017] By adopting the above technical solution, when the shading cloth of the shading mechanism is fully unfolded, the upper end of the second support rod extends upwardly at an angle toward the direction close to the first cushion body. At this time, under the action of gravity on the second support rod, the shading cloth tends to maintain the unfolded state. The second support rod of the shading mechanism can be fixed by passing the connecting belt through the metal ring and fixing it to the side of the headrest cushion by the snap buckle, thereby fixing the shading cloth with shading function.

[0019] By adopting the above technical scheme, the linkage mechanism includes connecting plates arranged on both sides of the headrest pad, two first linkage arms respectively hinged at one end arranged on the connecting plates, and two second linkage arms respectively hinged at one end arranged on the second support rod, so as to realize the headrest pad to realize the headrest function during the unfolding process of the shading cloth of the shading mechanism; at the same time, when the shading cloth of the shading mechanism is fully unfolded, the line connecting the rotation center of the second support rod along the vertical upward direction is used as the dividing line, and the first linkage arm and the second linkage arm are located on the side of the dividing line close to the first cushion body.

In addition, the headrest cushion 3 is turned over and supported on the second cushion body 2 to realize the headrest function.

[0030] As Figures 1 to 3 shown, a light-shielding mechanism 4 for realizing light shielding after unfolding is provided on the second cushion body 2. The light-shielding mechanism 4 includes two mounting seats 41 provided on both sides of the second cushion body 2, a first support rod 42 arranged between the two mounting seats 41 and in a "U" shape, a cushion cloth 43 arranged inside the first support rod 42 and under the headrest cushion 3, a second support rod 44 rotatably connected between the two mounting seats 41 and in a "U" shape, a plurality of intermediate support rods 45 rotatably connected to the mounting seats 41 and in a "U" shape, and a light-shielding cloth 46. The light-shielding cloth 46 is arranged between the first support rod 42, the plurality of intermediate support rods 45, and the second support rod 44. The second support rod 44 and the plurality of intermediate support rods 45 of the light-shielding mechanism 4 drive the light-shielding cloth 46 to unfold to realize the light-shielding function. Among them, the lengths of the first support rod 42, the second support rod 44, and the plurality of intermediate support rods 45 are different, and in the initial state, they can be on the side of the headrest cushion 3 away from the second cushion body 2.

[0031] As Figure 3 and Figure 4As shown, the second cushion body 2 is provided with a connecting sleeve 21 with a plug-in slot 211 on both sides, the opening of the plug-in slot 211 faces the side close to the first cushion body 1, the mounting seat 41 is transversely plugged into the plug-in slot 211 of the connecting sleeve 21, and a zipper 6 for detachable connection is provided between the cushion cloth 43 and the second cushion body 2. When the shading cloth 46 of the shading mechanism 4 is fully unfolded, the upper end of the second support rod 44 extends upwardly in a direction close to the first cushion body 1.

[0032] like Figures 3 to 5 As shown, a shading cloth 46 (see FIG. 1 ) is provided between the headrest pad 3 and the shading mechanism 4 to achieve the shading function when the headrest pad 3 is in the headrest function. Figure 2 ) is fixed with a fixing structure 5. The fixing structure 5 includes a limiting portion 51 which is integrally arranged on both sides of the headrest pad 3 and has a limiting groove 511, and a limiting sleeve 52 which is arranged at both ends of the second support rod 44 and is embedded in the limiting groove 511; when the limiting sleeve 52 of the second support rod 44 is embedded in the limiting groove 511, the limiting portion 51 is squeezed and deformed. At the same time, when the headrest pad 3 and the second support rod 44 of the shading mechanism 4 are in the initial state, the second support rod 44 is below the limiting portion 51; the operation steps of using the headrest pad 3 and the shading mechanism 4 are as follows: (S1) When multiple first pad bodies 1, second pad bodies 2, and headrest pads 3 are unfolded and laid flat on the ground, first, the second support rod 44 of the shading mechanism 4 is held and rotated. During this process, the second support rod 44 applies an upward force to the limiting portion 51, so that the headrest pad 3 rotates upward, and the headrest pad 3 flips over more than After the headrest pad 3 is turned 90 degrees, it automatically flips over under the action of gravity to realize the headrest function; (2) when the headrest pad 3 has realized the headrest function and the second support rod 44 is about to rotate to the limit state, pressure is applied to the two sides of the headrest pad 3 toward the middle to cause the headrest pad 3 to deform, thereby causing the second support rod 44 to rotate to the limit state, and then when the headrest pad 3 recovers its deformation, the limiting sleeve 52 of the second support rod 44 is embedded in the limiting groove 511 of the limiting portion 51 of the headrest pad 3 to be fixed.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, a first lifting ring 47 is provided on the second support rod 44, and a second lifting ring 11 is provided on the end of the first pad body 1 farthest from the second pad body 2, so as to facilitate lifting of the entire nap mat when it is folded.

[0034] Implementation effect: First, the padding cloth 43 of the shading mechanism 4 can prevent the headrest pad 3 from directly contacting the ground during use, thereby preventing the surface of the headrest pad 3 for the user's head to lean on from getting dirty, and the shading cloth 46 of the shading mechanism 4 can be opened after the second support rod 44 and the multiple middle support rods 45 are rotated to realize the shading function; in addition, for female users with long hair, their heads are surrounded by the shading mechanism 4, thereby preventing their hair from being scattered on the ground; at the same time, the shading mechanism 4 is located within the range of the padding cloth 43, and some mobile phones and other items used before going to bed can be temporarily placed for temporary storage, which are not easy to be lost; ultimately, the headrest pad 3 is prevented from getting dirty, a shading lunch break environment is provided for the user, the user's hair is prevented from getting dirty, and some items can be temporarily stored.

[0035] When the shading cloth 46 of the shading mechanism 4 is fully unfolded, the upper end of the second support rod 44 extends upwardly and obliquely toward the direction close to the first cushion body 1. At this time, under the action of gravity on the second support rod 44, the shading cloth 46 tends to remain in the unfolded state; at the same time, in conjunction with the fixing structure 5 provided between the headrest pad 3 and the shading mechanism 4, it is further ensured that the shading cloth 46 remains in the unfolded state, thereby avoiding the shading mechanism 4 from closing when it is accidentally touched.

[0036] By arranging a limiting portion 51 with a limiting groove 511 on both sides of the headrest pad 3, and arranging a limiting groove 511 at both ends of the second support rod 44, when the second support rod 44 is rotated into place, the limiting portion 51 will first be squeezed and deformed, and then when the limiting sleeve 52 is embedded in the limiting groove 511 of the limiting portion 51, the second support rod 44 of the shading mechanism 4 is fixed, thereby realizing the fixation of the shading cloth 46 with shading function.

[0037] When the second support rod 44 of the pillow and shading mechanism 4 is in the initial state, the second support rod 44 is below the limiting portion 51. At this time, during the unfolding process of the shading mechanism 4, the headrest cushion 3 can be driven to flip over and be in the headrest function. The operation steps are as follows: (S1) When the plurality of first cushion bodies 1, second cushion bodies 2, and headrest cushions 3 are unfolded and laid flat on the ground, first, the second support rod 44 of the shading mechanism 4 is held and rotated. During this process, the second support rod 44 applies an upward force to the limiting portion 51, so that the headrest cushion 3 rotates upward , and the headrest pad 3 automatically turns over under the action of gravity after turning over more than 90 degrees to realize the headrest function; (2) when the headrest pad 3 has realized the headrest function and the second support rod 44 is about to rotate to the limit state, pressure is applied to the two sides of the headrest pad 3 toward the middle to cause the headrest pad 3 to deform, thereby causing the second support rod 44 to rotate to the limit state, and then when the headrest pad 3 recovers its deformation, the limiting sleeve 52 of the second support rod 44 is embedded in the limiting groove 511 of the limiting portion 51 of the headrest pad 3 to be fixed.

[0038] The mounting seat 41 is inserted into the insertion slot 211 of the connecting sleeve 21, and the opening of the insertion slot 211 faces the side close to the first pad body 1. The pad cloth 43 and the second pad body 2 are detachably connected through the zipper 6, so that the shading mechanism 4 can be firmly installed and fixed; in addition, when the connection of the zipper 6 is cancelled and the connecting sleeve 21 and the mounting seat 41 are plugged in, the shading mechanism 4 can be disassembled, which has the function of selecting whether to install according to actual needs and facilitating disassembly and cleaning.

[0039] A first lifting ring 47 is provided on the second support rod 44, so that the shading mechanism 4 can be conveniently deployed by pulling the second support rod 44, and when the lunch nap mat is in a folded state as a whole, the first lifting ring 47 and the second lifting ring 11 are lifted, which has the function of facilitating the transportation of the lunch nap mat. By providing the first Velcro 8, the two first pad bodies 1 can be kept in a bonded state after folding, and by providing the second Velcro 9, the first pad body 1 and the second pad body 2 can be in a bonded state after folding, so that the lunch nap mat is not easy to fall apart when the folded state is carried. The thermal insulation inner core layer is a non-glue cotton processed by adding graphene to polyester masterbatch. At this time, the graphene is permanently implanted in the polyester fiber. While maintaining the excellent performance of traditional polyester fiber, the excellent thermal conductivity of graphene is utilized to make the thermal insulation inner core layer have excellent light absorption and heat generation functions. When exposed to natural light, the uniform graphene in the thermal insulation core layer can quickly absorb the heat energy in the light, and conduct it and wrap it in the thermal insulation core layer, thereby achieving the effect of rapid temperature rise after absorbing light, making the thermal insulation core layer have the characteristics of fast heating and high temperature rise, thereby improving the comfort of using the lunch nap mat.

[0040] Embodiment 2: A nap mat, such as Figure 3 and Figure 7 As shown, the difference from the embodiment 1 lies in the difference in the fixing structure 5 and the provision of a linkage mechanism 7. The fixing structure 5 includes two metal rings 53 with flat holes arranged at both ends of the shading cloth 46 near the second support rod 44, two connecting belts 54 with one end each arranged on the side of the headrest pad 3, and two snap fasteners 55 respectively arranged between the two sides of the headrest pad 3 and the other end of the connecting belt 54; the connecting belt 54 passes through the metal ring 53 and is fixed to the side of the headrest pad 3 through the snap fastener 55.

[0041] like Figure 1 , Figure 7 and Figure 8As shown, a linkage mechanism 7 is provided between the headrest pad 3 and the shading mechanism 4 to drive the headrest pad 3 to realize the headrest function during the unfolding process of the shading cloth 46 of the shading mechanism 4. The linkage mechanism 7 includes a connecting piece 71 provided on both sides of the headrest pad 3, two first linkage arms 72 respectively hingedly provided on the connecting piece 71 at one end, and two second linkage arms 73 respectively hingedly provided on the second support rod 44 at one end, and the other end of the first linkage arm 72 and the other end of the second linkage arm 73 are hinged; when the shading cloth 46 of the shading mechanism 4 is fully unfolded, the first linkage arm 72 and the second linkage arm 73 are located on the side of the dividing line close to the first cushion body 1, with the line connecting the rotation center of the second support rod 44 in the vertical upward direction as the dividing line.

[0042] Implementation effect: When the shading cloth 46 of the shading mechanism 4 is fully unfolded, the upper end of the second support rod 44 extends upwardly at an angle toward the direction close to the first cushion body 1. At this time, under the action of gravity on the second support rod 44, the shading cloth 46 tends to maintain the unfolded state. The connecting belt 54 passes through the metal ring 53 and is fixed to the side of the headrest cushion 3 through the snap buckle 55, so that the second support rod 44 of the shading mechanism 4 can be fixed, thereby realizing the fixation of the shading cloth 46 with shading function.

[0043] The linkage mechanism 7 includes a connecting piece 71 arranged on both sides of the headrest pad 3, two first linkage arms 72 respectively hinged at one end thereof and arranged on the connecting piece 71, and two second linkage arms 73 respectively hinged at one end thereof and arranged on the second support rod 44, so as to drive the headrest pad 3 to realize the headrest function during the unfolding process of the shading cloth 46 of the shading mechanism 4; at the same time, when the shading cloth 46 of the shading mechanism 4 is fully unfolded, the line connecting the rotation center of the second support rod 44 in the vertical upward direction is used as the dividing line, and the first linkage arm 72 and the second linkage arm 73 are located on the side of the dividing line close to the first cushion body 1. At this time, under the action of gravity on the first linkage arm 72 and the second linkage arm 73, the shading cloth 46 has a tendency to maintain the unfolded state.
