The present disclosure claims the priority to the Chinese patent application with the filing number 202220725644.7, filed on Mar. 29, 2022 with the Chinese Patent Office, and entitled “Pick-up Truck Mattress”, the contents of which are incorporated herein by reference in entirety.
The present disclosure relates to the field of inflatable beds, and in particular, relates to a pick-up truck mattress.
The inflatable beds utilize the characteristic that air is permeable to enable the human body to be fit with the bed completely when sleeping, and allow various parts of the human body to be uniformly stressed, so that the blood circulation disorder caused by uneven stress of the conventional beds is effectively improved. The air bed is also known as health care bed in the foreign countries. The inflatable beds can be inflated when in use, with an inflation amount being controlled. The inflatable beds can be deflated when not in use, thus reducing the volume, facilitating storage, and being quite flexible to use. The inflatable beds in the prior art are substantially in regular shapes, such as square or circular shape, and cannot be used directly in the pick-up trucks.
An objective of the present disclosure is to provide a pick-up truck mattress, which can be adapted to the structure of a pick-up truck, perfectly matches with the pick-up truck, and is not easy to have obvious bulges or depressions after being placed on the pick-up truck, with high usage comfort.
An embodiment of the present disclosure is implemented as follows.

In an optional embodiment, an outer side wall of the annular air chamber does not protrude from outer sides of the convex portions.
The embodiments of the present disclosure have the following beneficial effects.
To sum up, the pick-up truck inflatable mattress provided in the present embodiment can be firstly placed in the cargo compartment of the pick-up truck, and the inflatable mattress can be allowed to form two avoidance grooves whose positions are corresponding to positions of two rear wheels of the pick-up truck. Then, the inflatable mattress is inflated by an inflation pump for inflation operation, and after the inflatable mattress is inflated, the two avoidance grooves perfectly avoid the two convex shell portions configured, in the cargo compartment, to positioning the rear wheels, that is, the two convex shell portions can cooperate with the two avoidance grooves. In this way, the convex shell portions are utilized to position the inflatable mattress, so that the inflatable mattress is not easy to move with respect to the cargo compartment, improving the stability; moreover, the convex shell portions provided inside the cargo compartment in a protruding manner will not interfere with the inflatable mattress, and the inflatable mattress is not easy to be jacked up, thus after being laid in the cargo compartment of the pick-up truck, the inflatable mattress has high flatness and is comfortable to use. Moreover, the annular air chamber is located at one sides of the avoidance grooves and shields the avoidance grooves, thus, the annular air chamber will shield the convex shell portions, and the user will not directly contact the convex shell portions, with high comfort level. The inflatable mattress, designed with independent main air chamber and annular air chamber, has high strength, is not easy to be deformed, and has high comfort level, compared with that designed with one air chamber.

At present, when a pick-up truck is used, a mattress can be placed in a cargo compartment of the pick-up truck, and people can rest on the mattress, thus improving the comfort of use. In the prior art, the mattresses are mostly inflatable mattresses each having one air chamber. However, in order to enable the mattress to avoid convex shell portions corresponding to rear wheels in the cargo compartment, the mattress needs to be set relatively thick, thus the stability of the mattress is poor.
In view of this, the designer designs a pick-up truck mattress. By designing the mattress with two air chambers in communication with each other, an air chamber located at the periphery can enhance the strength of edges of a middle air chamber, and the stability is good during use.
Referring to
In the present embodiment, it should be understood that the main air chamber 100 and the annular air chamber 200 are in communication with each other, and thus when an inflation pump is used to perform inflation, a gas can simultaneously or sequentially enter the main air chamber 100 and the annular air chamber 200, so that the main air chamber 100 and the annular air chamber 200 satisfy the use requirements. For example, a flow dividing pipe in communication with the annular air chamber 200 may be provided in the main air chamber 100. The flow dividing pipe is in communication with the main air chamber 100, and the flow dividing pipe is provided therein with a unidirectional valve to allow only the gas in the main air chamber 100 to enter the annular air chamber 200. In the case that the inflation pump is used to inflate the main air chamber 100, when air pressure in the main air chamber 100 reaches a certain value, the unidirectional valve is opened under the action of the air pressure, and then the gas enters the annular air chamber 200 through the flow dividing pipe to inflate the annular air chamber 200.
In addition, the main air chamber 100 and the annular air chamber 200 can be independently provided with an air release valve, so as to independently control the air pressure in the main air chamber 100 and the annular air chamber 200, and further independently control the flexibility.
Referring to
Further, the main air chamber 100 further includes first pull straps 150, and the first pull straps 150 each have one end connected to the top wall 140, and the other end connected to the bottom wall 110, improving the stability of the main air chamber 100.
Optionally, the second enclosure 130 may be provided as an integrated structure, or the second enclosure 130 is formed by connecting a plurality of connecting pieces end to end in sequence. The second annular edge 124 of the first enclosure 120 is connected to the third annular edge of the second enclosure 130, wherein the joint where the two are connected is a first connecting portion whose profile is in an “H” shape. The fourth annular edge 132 of the second enclosure 130 is connected to an outer edge of the top wall 140, wherein the joint where the two are connected is a second connecting portion whose profile is in an “H” shape.
In the present embodiment, optionally, the annular air chamber 200 surrounds the second enclosure 130, and an outer circumferential wall of the annular air chamber 200 does not protrude beyond the convex portions 121 of the second enclosure 130, and further, the outer circumferential wall of the annular air chamber 200 is substantially located in the same plane as an outer side of the convex portions 121 of the second enclosure 130.
Optionally, the annular air chamber 200 includes an annular sheet 210, a third enclosure 220, and a second annular sheet 210. The annular sheet 210 and the second annular sheet 210 are both connected to the third enclosure 220. The annular sheet 210, the third enclosure 220, and the second annular sheet 210 are all provided around the second enclosure 130 and define an annular cavity, together with the second enclosure 130. A side of the annular sheet 210 away from the third enclosure 220 is connected to the second connecting portion, and a side of the second annular sheet 210 away from the third enclosure 220 is connected to the first connecting portion.
Further, the annular sheet 210 includes two first connecting bodies 211 and two first blocking bodies 212. The two first connecting bodies 211 and the two first blocking bodies 212 are arranged alternately and connected end to end; and the two first blocking bodies 212 each protrude beyond the first connecting bodies 211 in a direction from the outside to the inside of the annular air chamber 200. The second annular sheet 210 includes two second connecting bodies 211 and two second blocking bodies 221. The two second connecting bodies 211 and the two second blocking bodies 221 are arranged alternately and connected end to end; and the two second blocking bodies 221 each protrude beyond the second connecting bodies 211 in a direction from the outside to the inside of the annular air chamber 200. The two first blocking bodies 212 and the two second blocking bodies 221 are respectively provided corresponding to and opposite to each other in the thickness direction of the main air chamber 100, and the second blocking bodies 221 are configured to shield one sides of the avoidance grooves 122 close to the top wall 140. That is to say, after the mattress is inflated, positions where the first blocking bodies 212 and the second blocking bodies 221 are located are corresponding to the positions of the avoidance grooves 122, to shield one sides of the avoidance grooves 122 away from the bottom wall 110, so that after the mattress is placed in the cargo compartment of the pick-up truck, portions of the annular air chamber 200 corresponding to the second blocking bodies 221 cover the convex shell portions configured to avoid the rear wheels on the cargo compartment.
Optionally, the annular air chamber 200 further includes second pull straps 230, and the second pull straps 230 are simultaneously connected to the annular sheet 210 and the second annular sheet 210. Specifically, the second pull straps 230 are simultaneously connected with the paired first blocking bodies 212 and the second blocking bodies 221.
The pick-up truck mattress provided by the present embodiment has high use comfort and high stability.
The above are merely for preferred embodiments of the present disclosure and not intended to limit the present disclosure. For one skilled in the art, various modifications and variations can be made to the present disclosure. Any amendments, equivalent replacements, improvements and so on made within the spirit and principle of the present disclosure should be covered within the scope of protection of the present disclosure.
