Abstract

The anti-pinch electric bed includes a base, a load-bearing group pivotally connected to the base, a swing group pivotally connected to the base and capable of driving the load-bearing group to swing relative to the base, and a drive group. The swing group has a long slot, and the long slot has a first slot end and a second slot end. The drive group has a driving body pivotally connected to the base, a telescopic column capable of telescoping relative to the driving body, and a slot rod connected to the telescopic column, and the slot rod can be slidably inserted into the long slot of the swing group. When the slot rod abuts against the first slot end and the telescopic column is shortened relative to the driving body, the driving group drives the load-bearing group to swing away from the base through the swing group; and when the telescopic column is extended relative to the driving body, causing the load-bearing group to swing and approach the base, and when the load-bearing group is blocked by external force, the telescopic column continues to extend relative to the driving body, causing the slot rod to slide from the first slot end to the second slot end. In this way, when the load-bearing group is blocked, the continuous action of the driving group will not cause the swing group to deflect, thereby solving the problem that the known load-bearing group still deflects.

Description

Anti-pinch electric bed

Technical Field

The application relates to the electric bed technology, in particular to an anti-pinch electric bed.

Background

The present invention relates to an electric bed, and more particularly to an electric bed with a support unit and a driving unit, wherein the support unit is arranged on a base in a tilting manner, and the driving unit is used for supporting an upper body and/or a lower body of a user through a mattress. When the driving set drives the carrying set to swing from top to bottom and a foreign object or a human body is located below the carrying set, if the carrying set continuously swings, the foreign object or the human body may be clamped between the carrying set and the base to be injured, or the foreign object may cause damage to components of the electric bed, so that a safety protection mechanism needs to be provided to improve the defect of the conventional electric bed. Although some electric beds are provided with sensors to improve the above problems, the sensors are used to detect the presence or absence of foreign matters and control the operation of the electric beds, which is not only costly, but also may have problems of incomplete and reliable sensing. Thus, there remains a need for such an electric bed that can be simplified and that ensures safety.

Disclosure of utility model

The main objective of the present application is to provide an anti-pinch electric bed, which can avoid pinching objects or human bodies or damaging the electric bed without driving the bearing set to swing when the bearing set is blocked and the driving set is still operating.

In order to achieve the above purpose, the application provides an anti-pinch electric bed, which comprises a base, a bearing group, a connecting swing group and a driving group. The bearing group is pivoted to the base and can swing relative to the base. The continuous swinging group is pivoted to the base and can swing relative to the base, and is connected with the bearing group to drive the bearing group to swing relative to the base, and the continuous swinging group is provided with a long groove, and the long groove is provided with a first groove end and a second groove end. The driving group is provided with a driving body pivoted to the base, a telescopic column capable of stretching relative to the driving body, and a slot rod connected to the telescopic column, wherein the slot rod can slidably penetrate through the long groove of the connecting swing group. When the slot rod is propped against the first slot end and the telescopic column is shortened relative to the driving body, the driving group drives the swinging group to swing relative to the base, so that the bearing group is driven to swing relative to the base and away from the base; when the telescopic column stretches relative to the driving body, the bearing group swings relative to the base and is close to the base, and the bearing group is blocked by external force, the telescopic column stretches continuously relative to the driving body, so that the slot rod slides from the first slot end to the second slot end.

By the technical characteristics, when the bearing group deflects downwards and touches the object to be blocked, the telescopic column of the driving group continuously acts, and only the slot rod slides in the long slot of the connecting group, at the moment, the connecting group can not be acted by the driving group, so that the connecting group can be prevented from continuously swinging downwards to clamp objects or human bodies or avoid damaging the electric bed.

The application provides for the detailed construction, features, assembly or manner of use of the anti-pinch electric bed, as will be described in the detailed description of the embodiments that follow. However, those of ordinary skill in the art will appreciate that the detailed description and specific embodiments presented herein are meant to be illustrative of the application and are not limiting upon the scope of the application as claimed.

Detailed Description

Applicant hereby gives notice that throughout this specification, including the embodiments described below and claims, directional terms may be employed to advantage in all directions in the drawings. Next, in the embodiments to be described below and the drawings, the same component numerals denote the same or similar components or structural features thereof.

Referring to fig. 1 to 7, the anti-pinch electric bed according to the preferred embodiment of the present application mainly includes a base 10, a carrying set 20, a swinging set 30 and a driving set 40. In the figure, the front and rear sides of the electric bed are provided with a group of bearing groups 20, a swinging group 30 and a driving group 40 which are matched with each other, and the structure and the action mechanism of the mechanisms at the front and rear sides are similar, so the embodiment is only taken as one side for illustration.

The base 10 has three first pivoting portions 11, a second pivoting portion 13, and two escape grooves 12. Each first pivoting portion 11 has a hole and is coaxially disposed, wherein two first pivoting portions 11 are located at two side edges, the other first pivoting portion 11 is located in the middle of the bottom surface, each escape slot 12 is located at two side edges and is formed in an arc shape with the first pivoting portions 11 at two sides as the center, and the second pivoting portion 13 has a hole and is located at the other side. Next, the top surface of the base 10 is directly or indirectly fixed with a fixing member 16 by a locking assembly (not shown).

The bearing set 20 has two bearings 21 and a plurality of bearings 22. Each of the swing supporting pieces 21 has a third pivot portion 211 and a fourth pivot portion 212, each of the third pivot portions 211 has a first pivot portion P1 for pivotally connecting each of the first pivot portions 11 of the base 10, and each of the fourth pivot portions 212 has a first end. Each carrier 22 is pivotally connected to each of the swing pieces 21 by a plurality of pivot pieces 23. In this embodiment, the fixing member 23 and the carrying member 22 are used for supporting a mattress (not shown), the fixing member 23 corresponds to the hip position of the user, the carrying member 22 corresponds to the back and head position of the user, and one end of the carrying member 22 is pivotally connected to the fixing member 23, so that the carrying member 22 can swing up and down (i.e. away from or near the base 10) relative to the fixing member 23 (i.e. relative to the base 10).

The swinging set 30 has a cross bar 30a, two end pieces 30b respectively fixed at two ends of the cross bar 30a, three fifth pivoting portions 31 respectively located at the two end pieces 30b and the middle section of the cross bar 30a, two sixth pivoting portions 32 respectively located at the two end pieces 30b, two slot pieces 33 respectively extending downward from the middle section of the cross bar 30a, and two slot pieces 331 respectively located at the two slot pieces 33. Each fifth pivot portion 31 has a hole and is pivoted to each first pivot portion 11 of the base 10 by each first pivot member P1, each sixth pivot portion 32 has a hole and is pivoted to each fourth pivot portion 212 of the carrying set 20 by each second pivot member P2, and each second pivot member P2 is inserted into each escape slot 12 of the base 10. Each slot piece 33 is linked with the first pivot piece P1 as a center, each slot piece 33 is provided with a long slot 331 which takes an arc shape with the first pivot piece P1 as a center, each long slot 331 is provided with a first slot end 3311 and a second slot end 3312, and each first slot end 3311 and each second slot end 3312 are respectively positioned at two ends of each long slot 331.

The bearing set 20 and the swinging set 30 are pivoted to the base 10 together by the first pivot P1, in other words, the pivot center of the swinging set 30 and the base 10 and the pivot center of the bearing set 21 and the base 10 of the bearing set 20 are coaxial.

The drive group 40 has a drive body 41, a telescopic column 42 and a socket rod 43. The driving body 41 is pivotally connected to the second pivot portion 13 of the base 10 by the third pivot member P3, the telescopic column 42 is telescopic by the driving body 41, the telescopic column 42 is located between the two slots 33, the slot rod 43 is connected to the front end of the telescopic column 42, and the slot rod 43 is disposed through each of the elongated slots 331 of the swinging set 30, so that when the telescopic column 42 is elongated or shortened relative to the driving body 41 by the driving body 41, the slot rod 43 can slide between each of the first slot end 3311 and the second slot end 3312.

Wherein the first slot end 3311 of the wobble set 30 is closer to the drive set 40 than the second slot end 3312. The slot rod 43 of the driving set 40 can abut against the first slot end 3311 of the swinging set 30, and the swinging angle of the swinging set 30 is controlled by the telescopic column 42. Specifically, when the telescopic column 42 of the driving set 40 is shortened, the telescopic column 42 drives the swinging set 30 through the slot 33 to drive the swing bearing 21 to pivot counterclockwise about the first pivot P1 as a rotation center, so that the load bearing set 20 is deflected and lifted away from the base 10, and when the telescopic column 42 of the driving set 40 is extended, the load bearing set 20 is deflected and lowered relative to the base 10 to approach the base 10. The manner of operation and efficacy of the anti-pinch electric bed provided by the preferred embodiment of the present application is further described below.

Fig. 8 shows that the driving set 40 is extended, the slot rod 43 of the telescopic column 42 of the driving set 40 abuts against the first slot end 3311 of the slot 331 of the swinging set 30, and the bearing set 20 is in a horizontal posture relative to the base 10, at this time, if the telescopic column 42 is shortened, the slot rod 43 abuts against the first slot end 3311, the telescopic column 42 pulls the slot piece 33 to rotate the swinging set 30 counterclockwise, so as to drive the bearing set 20 to swing upwards. In fig. 9, the driving set 40 is shown to be minimized, and the swinging set 30 is pulled to rotate counterclockwise, so as to drive the bearing set 20 to swing upwards to the top dead center.

When the operation carrying set 20 is swung downwards from the state shown in fig. 9, the telescopic column 42 of the driving set 40 is controlled to be in a state that can be lengthened or actively lengthened, at this time, the carrying set 20 will have a natural tendency to swing downwards due to the effect of the weight of the carrying set 20 or the effect of the mattress and the weight of the user, so when the carrying set 20 is swung downwards, the swinging set 30 is driven to rotate clockwise by the second pivot piece P2 around the first pivot piece P1, and at this time, the slot rod 43 of the driving set 40 can still be kept at the position of the first slot end 3311 of the slot 331 of the linkage swinging set 30. Fig. 4 shows the carrier 20 being tilted downward from the state of fig. 9 to an inclined state in which the carrier 20 forms an angle a with the base 10 or horizontally, and the slot bar 43 is still maintained at the first end 3311 of the slot 331 as described above.

As shown in fig. 10, when the carrying set 20 is continuously deflected downwards from the state of fig. 4 but is blocked by external force or foreign matter, the driving set 40 still continues to stretch, and the slot rod 43 slides along the long slot 331 from the first slot end 3311 to the second slot end 3312 until abutting against the second slot end 3312, and during this sliding process, the carrying set 20 is temporarily not deflected downwards again due to the blocking of external force or foreign matter, so that the same included angle a is still maintained between the carrying set 20 and the base 10 or the horizontal. In other words, when the foregoing occurs, the electric bed provided by the present application provides a buffering time (i.e. the time for the slot rod 43 to slide from the first slot end 3311 to the second slot end 3312) to allow the user to remove the external force or the foreign matter, or when the external force is caused by the load-bearing set 20 of the lower hem pressing against the human body, the touched person may have the buffering time to leave the path of the lower hem of the load-bearing set 20 to avoid further clipping injury by the load-bearing set 20, or may also issue a warning sound and light or control the driving set 40 to stop when the load-bearing set 20 stops deflecting downward to continuously operate the driving set 40, so as to ensure safety.

As can be seen from the above description, in the anti-pinch electric bed provided in the present embodiment, when the downward deflection of the carrying set 20 is blocked, the driving set 40 continuously drives the extension of the telescopic column 42 to prevent the swinging set 30 from deflecting, i.e. to prevent the carrying set 20 from being deflected, thereby avoiding the pinching injury or the electric bed damage, and achieving the purpose of the present application.

In addition to the above examples, the present application can be alternatively implemented as follows, and the object of the present application can be achieved.

For example, the first pivot portion 11 of the base 10 is not limited to the aforementioned three but may be one. The number of the load bearing members 21 of the load bearing group 20 is not limited to two as described above, and may be one instead. The fifth pivot portion 31 of the swinging set 30 is not limited to the three as described above, and may be one or two. The number of the groove pieces 33 of the swing set 30 is not limited to two as described above, and may be one.

Or the pivot center of the swinging set 30 and the base 10 is not limited to the pivot center of the swinging piece 21 of the bearing set 20 and the base 10, and can be changed into different pivot centers.

Or the carrier 22 is not limited to having to connect the pendulum 21 with the pivot connection piece 23 as before, but may instead be directly fixed to the pendulum 21.

In addition, the base 10, the carrying set 20, the swinging set 30 and the driving set 40 are not limited to be disposed only on the front side of the electric bed, or only on the rear side of the electric bed, but may be disposed on both the front and rear sides of the electric bed, and the front and rear carrying sets 20 may be connected to each other or not. Finally, it should be understood that the components disclosed in the foregoing embodiments of the present application are merely exemplary, and are not intended to limit the scope of the present application, and other equivalents and alternatives thereof are also intended to be encompassed by the claims.
