- Please refer to
FIG. 1 toFIG. 9 , the specific structure of a preferred embodiment of the present invention is shown, which is an intelligent and multifunctional sofa bed, including asofa seat 1, amovable frame 2, adriving device 3, a folding frame 4 and afirst transmission device 5. - Referring to
FIG. 1 ,FIG. 2 ,FIG. 3 andFIG. 7 , thesofa seat 1 is provided with abottom frame 11, themovable frame 2 is movably installed on thebottom frame 11, thedriving device 3 is installed on thebottom frame 11 and is used to drive themovable frame 2 to reciprocate back and forth in high frequency to generate vibration; the folding frame 4 is rotatably installed on themovable frame 2, thefirst transmission device 5 is installed on themovable frame 2, and is used to drive the folding frame 4 to rotate, thereby realizing the folding or unfolding of the folding frame 4; thefirst transmission device 5 is used to drive the folding frame 4 to be folded on themovable frame 2 to form a rest sofa in a first position; thefirst transmission device 5 is used to drive the folding frame 4 to unfold beyond themovable frame 2 to form a rest bed in a second position. Specifically, as themovable frame 2, thedriving device 3, the folding frame 4 and thefirst transmission device 5 are provided, thefirst transmission device 5 can drive the folding frame 4 to perform automatic folding, therefore, the problem of inconvenient operation of the traditional manual folding sofa bed is solved, and the convenience of use is improved; in addition, thedriving device 3 drives themovable frame 2 to generate high-frequency reciprocating motion, the user can turn on a vibration mode to relax the body while resting, which enriches the functions of the sofa bed and improves the user experience. - Next, the folding frame 4 includes a
first folding frame 41, asecond folding frame 42 and athird folding frame 43, one end of thefirst folding frame 41 is pivotally connected to themovable frame 2, one end of thesecond folding frame 42 is pivotally connected to the other end of thefirst folding frame 41, one end of thethird folding frame 43 is pivotally connected to the other end of thesecond folding frame 42. In the first position, thefirst transmission device 5 drives thefirst folding frame 41 together with thesecond folding frame 42 and thethird folding frame 43 to fold until thefirst folding frame 41 and thesecond folding frame 42 are folded and attached together to form a backrest of the rest sofa, and thethird folding frame 43 is translated onto themovable frame 2 to form a cushion of the rest sofa; in the second position, thefirst transmission device 5 drives thefirst folding frame 41 together with thesecond folding frame 42 and thethird folding frame 43 to unfold, thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are co-linear and coplanar to form a rest bed. - The
first folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are pivotally connected by setting a pivot at one end and a shaft hole for inserting the pivot at the other end, alternatively, thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are connected by hinges. Specifically, one end of thefirst folding frame 41 is pivotally connected to the upper rear side of themovable frame 2. Thefirst transmission device 5 drives thefirst folding frame 41 to rotate upward and backward when folded, thereby driving thesecond folding frame 42 rotates downward and backward, and makes thefirst folding frame 41 and thesecond folding frame 42 overlap in the front and rear directions, and thesecond folding frame 42 drives thethird folding frame 43 to move backward and above themovable frame 2. It can be seen that thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are ingeniously pivoted, then the folding action is simple and easy to realize. And at least one cushion is provided above thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43. - Furtherly, one end of the
third folding frame 43 away from thesecond folding frame 42 is provided with a roller member that is rolled and held on the bearing surface of thebottom frame 11. The roller member includes asupport leg 431 and aroller 432, thesupport leg 431 is installed on the bottom of thethird folding frame 43 and extending downward, theroller 432 is installed at the bottom of thesupport leg 431. Thethird folding frame 43 assist its own movement via theroller 432 when folded. On one hand, the smoothness of the movement of thethird folding frame 43 during folding is improved, on the other hand, the noise generated when thethird folding frame 43 moves is eliminated. - Referring to
FIG. 1 ,FIG. 2 ,FIG. 3 andFIG. 8 , the sofa bed further includes a weight sensor 6, alimit switch 7 and acontrol unit 8. The weight sensor 6, thelimit switch 7 and thefirst transmission device 5 are respectively connected with thecontrol unit 8 in signal. The weight sensor 6 and thelimit switch 7 transmit signals to thecontrol unit 8, thecontrol unit 8 controls thedriving device 3 and thefirst transmission device 5 to work. - Continued, the weight sensor 6 is used to identify the weight of the folding frame 4 and trigger the folding frame 4 to fold. The weight sensor 6 is installed on the
movable frame 2. When the weight sensor 6 recognizes that the weight is below the set value, thefirst transmission device 5 drives the folding frame 4 to automatically fold on themovable frame 2. Specifically, when the folding frame 4 is unfolded into a sofa bed, thefirst folding frame 41 abuts against the weight sensor 6; when the folding frame 4 is folded into a sofa, thethird folding frame 43 abuts against the weight sensor 6. As an example, when thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are opened, it is now a sofa bed, thefirst folding frame 41 abuts against the weight sensor 6, and obtains the weight setting value M1 according to the weight when thefirst folding frame 41 abuts against the weight sensor 6. - In more detail, once the user sits or places heavy objects on the
first folding frame 41, thesecond folding frame 42 and thethird folding frame 43, thefirst transmission device 5 stops when the weight is greater than the set value M1, in order to prevent thefirst transmission device 5 from being automatically folded when there is a heavy object on the folding frame 4. In this way, it can be ensured that during the automatic folding process driven by thefirst transmission device 5, there will be no heavy objects on the folding frame 4, and this design can protect the sofa bed. - Once the user leaves, the weight of the folding frame 4 is below the set value Ml, at this time, the weight sensor 6 will send a signal to the
control unit 8, thecontrol unit 8 will control thefirst transmission device 5 to fold the folding frame 4, so as to realize the function of automatic folding when the user leaves. It should be noted here that thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are pivotally connected. As thefirst folding frame 41, thesecond folding frame 42 and thethird folding frame 43 are unfolded, even when only thefirst folding frame 41 abuts against the weight sensor 6, the weight of thesecond folding frame 42 and thethird folding frame 43 is transferred to thefirst folding frame 41 after being unfolded. - Continued, there are two
limit switches 7, the twolimit switches 7 are signally connected to thefirst transmission device 5 via thecontrol unit 8. When the folding frame 4 rotates to trigger one of thelimit switches 7, thefirst transmission device 5 stops working so that the folding frame 4 is folded. When the folding frame 4 rotates to trigger anotherlimit switch 7, thefirst transmission device 5 stops working so that the folding frame 4 completes the folding. Specifically, thelimit switch 7 includes atrigger 71 and asensing piece 72, thetrigger 71 is installed on the upper rear side of themovable frame 2, thesensing piece 72 is installed on the rear side of thefirst folding frame 41. When thefirst folding frame 41 is rotated to be folded, thesensing piece 72 contacts thetrigger 71, thetrigger 71 transmits a signal to thecontrol unit 8, thecontrol unit 8 controls thefirst transmission device 5 to stop working, thereby completing the folding. The principle of triggering to unfold is the same as that of folding, which will not be described here. - Referring to
