Description

a baby cradle

technical field

The utility model relates to a baby cradle.

Background technique

Because the baby is sleeping most of the time every day, and often feels uncomfortable due to hunger, peeing and other reasons, it is usually necessary to place the baby in a special cradle, which is convenient for adults to take care of when the baby is crying.

However, the traditional cradle cannot be shaken automatically. Once the adult has something to leave for a long distance and for a long time, he cannot shake the cradle in time to comfort the baby. Therefore, someone has added a voice-activated drive system to the cradle. When the voice-activated switch of the voice-activated system receives the cry of the baby, the voice-activated drive system will control the cradle to shake and comfort the baby. However, because the way of shaking is usually left and right, which is quite different from the movement of the fetus in the mother's body (the movement of the fetus in the mother's body is similar to ups and downs), so this kind of shaking from side to side makes the baby feel uncomfortable and affects Soothing effect.

For example, Chinese patent document 201718869U "intelligent electric multifunctional cradle" discloses a cradle, which is composed of a cradle body, a main control CPU, an infrared emitting device, and a remote controller. The main control CPU and the infrared emitting device are connected to collect signals and control the work of the multifunctional cradle. . It also includes a magnetic driving device, which generates repelling and attracting magnetic power with the permanent magnet on the cradle main body.

The above-mentioned cradle adopts the way of shaking from side to side, so although it can control the cradle to shake after receiving the cry of the baby to comfort the baby, but because this way is quite different from the movement of the fetus in the mother's body, the effect Relatively poor.

For this reason, the applicant improved the existing cradle and applied for a patent, the patent number is 201220586198.2, and the name is "voice-activated baby cradle". The voice-activated baby cradle includes a voice-activated drive system, a cradle body, a positioning frame, a support frame, a protective cover and at least two springs, the voice-activated drive system is installed on the support frame, and it is characterized in that: the two ends of each spring are respectively connected The supporting frame and the positioning frame, the cradle body is placed on the positioning frame. The protective cover is sleeved on the corresponding spring, and the top end of the protective cover is installed on the hanging end of the suspension rod above the corresponding spring. Since the movement mode of the cradle body is changed from shaking from side to side to up and down, which is closer to the state of the fetus in the mother's body, it can make the baby feel more comfortable, and two or more springs located outside the cradle body are used to pull the cradle body , can make the cradle body more uniform in force, and can prevent the spring from moving above the cradle body, affecting the baby's sleep, and it is also convenient for adults to take and place the baby and the cradle body.

However, the applicant found through a large number of experiments that since the spring of this baby cradle is located above the cradle body, once an adult or baby touches the spring during use, the constantly expanding and contracting spring is likely to pinch the skin of the adult or baby, causing injury. Even if the protective cover is added, the bottom end of the spring will still be exposed, and there is still a potential safety hazard. In addition, once the baby turns over, the center of gravity of the cradle will shift, which will cause friction between the spring and the protective cover, which will not only cause wear and tear on the spring and protective cover, seriously affect the service life of the spring and protective cover, but also generate noise, affecting the baby's sleep.             

Invention content

The technical problem to be solved by the utility model is to provide a baby cradle, which can effectively prevent adults or babies from touching the springs, and at the same time prevent as much as possible Wear springs to avoid noise. The technical scheme adopted is as follows:

A baby cradle, comprising a cradle body, a bottom frame, and a cradle lifting mechanism, the cradle lifting mechanism is installed on the bottom frame, and the cradle lifting mechanism is connected to the cradle body, and it is characterized in that: the baby cradle also includes at least two elastic supports mechanism, the bottom ends of each elastic support mechanism are fixed on the chassis, and the top ends of each elastic support mechanism are connected to the cradle body.

In a preferred solution, the elastic support mechanism includes a support protection sleeve, a positioning ring, a spring and a telescopic rod, the bottom end of the support protection sleeve is fixed on the chassis, and the positioning ring is installed on the top end of the support protection sleeve On the opening, the top end of the telescopic rod is connected to the cradle body, the bottom end of the telescopic rod passes through the positioning ring and is inserted into the support protection sleeve, the spring is located in the support protection sleeve and the spring is sleeved on the telescopic rod, The positioning ring is connected, and the telescopic rod is connected at the bottom end of the spring. Since the telescopic rod is restricted by the positioning ring, it is difficult to move in the horizontal direction (that is, shake), so the telescopic rod can only rise or fall along the vertical direction, which makes it impossible for the baby to roll over and the center of gravity of the cradle itself to shift. Acts on the spring so the spring does not rub against the support protection sleeve or telescoping rod.

In a better solution, except for the connection between the top end of the spring and the positioning ring, and the connection between the bottom end of the spring and the telescopic rod, there are gaps between other parts of the spring and the support protection sleeve and between the telescopic rod. The connection between the top end of the spring and the positioning ring will contact the positioning ring, and the connection between the bottom end of the spring and the telescopic rod will contact the telescopic rod. And spring except spring top and positioning ring junction, spring bottom and telescopic rod junction, other parts all do not contact support protection sleeve and telescopic rod. In this way, it is possible to better avoid the friction between the spring and the telescopic rod or the support protection sleeve, causing wear and tear, affecting the life of parts such as the spring, and also better avoiding noise from friction and affecting the baby's sleep.

More preferably, the elastic support mechanism further includes a telescopic rod positioning ring, the telescopic rod positioning ring is installed on the telescopic rod, and the telescopic rod positioning ring is located under the spring and inside the support protection sleeve.

In a better solution, the top end of the elastic support mechanism is connected to the edge of the top opening of the cradle body.

In a better solution, there are three or four elastic support mechanisms.

Compared with the prior art, the beneficial effect of the utility model is that, since the original suspension structure is replaced by an elastic support mechanism, the baby in the cradle body can be effectively prevented from being injured by the spring; since the spring is completely located in the support protection sleeve, The safety performance is greatly improved. Since the friction between the spring and other parts is effectively avoided, the life of the spring and other parts is significantly extended, which greatly reduces the cost of maintenance and use; the improved structure reduces the consumption of materials and the baby The space occupied by the cradle effectively reduces the production cost, and the baby cradle is lighter and smaller, more convenient to move, and easier to place and store.

Detailed ways

Example 1

As shown in Figures 1-3, the baby cradle in this embodiment includes a cradle body 1, a chassis 2, a cradle lifting mechanism 9 and four elastic support mechanisms 3, and the cradle lifting mechanism 9 is installed on the chassis 2, And the cradle lifting mechanism 9 is connected to the cradle body 1, the bottom ends of each elastic support mechanism 3 are fixed on the chassis 2, and the top ends of each elastic support mechanism 3 are connected to the edge of the top opening of the cradle body 1.

The elastic support mechanism 3 includes a support protection sleeve 4, a positioning ring 5, a spring 6, a telescopic rod 7 and a telescopic rod positioning ring 8, and the bottom end of the support protection sleeve 4 is fixed on the chassis 2. The positioning ring 5 is installed on the top opening of the support protection sleeve 4, the top end of the telescopic rod 7 is connected to the cradle body 1, the bottom end of the telescopic rod 7 passes through the positioning ring 5, and is inserted into the support protection sleeve 4, and the spring 6 Located in the support protection sleeve 4 and the spring 6 is sleeved on the telescopic rod 7, the top end of the spring 6 is connected to the positioning ring 5, the bottom end of the spring 6 is connected to the telescopic rod 7, and the telescopic rod positioning ring 8 is installed on the telescopic rod 7 , and the retractable rod positioning ring 8 is located below the spring 6 and inside the support protection sleeve 4 . Since the telescopic rod 7 is limited by the positioning ring 5 and the telescopic rod positioning ring 8, it is difficult to move (i.e. shake) in the horizontal direction, so the telescopic rod 7 can only rise or fall along the vertical direction, which makes even if the baby turns over , the center of gravity of the cradle body 1 is shifted, and the spring 6 will not be affected, so the spring 6 will not rub against the support protection sleeve 4 or the telescopic rod 7 .

In addition to the connection between the top of the spring 6 and the positioning ring 5 and the connection between the bottom of the spring 6 and the telescopic rod 7, the spring 6 has a gap between the other parts of the spring 6 and the support protection sleeve 4 and between the telescopic rod 7. void. The joint between the top of the spring 6 and the positioning ring 5 will contact the positioning ring 5, and the joint between the bottom end of the spring 6 and the telescopic rod 7 will contact the telescopic rod 7. And spring 6 except spring 6 tops and positioning ring 5 junctions, spring 6 bottoms and telescopic rod 7 junctions, other parts all do not contact support protection sleeve 4 and telescopic rod 7. Like this, can better avoid that spring 6 and telescopic bar 7 or supporting protective sleeve 4 rub against, cause wearing and tearing, affect the lifespan of parts such as spring 6, also can avoid friction to produce noise better, affect baby's sleep.

In the initial state, the four elastic support mechanisms 3 provide support for the cradle body 1, and the cradle body 1 is located at the highest position. When the cradle lifting mechanism 9 pulls down the cradle body 1, when the pulling force of the cradle lifting mechanism 9 is greater than the supporting force of the four elastic support mechanisms 3, the cradle body 1 overcomes the elastic force of the spring 6 and descends until the cradle body 1 is at the lowest point. When the pulling force of the cradle lifting mechanism 9 is less than the supporting force of the four elastic supporting mechanisms 3, the elastic force of the spring 6 drives the cradle body 1 to rise. The cradle lifting mechanism 9 drives the cradle body 1 to go up and down repeatedly, so as to realize the purpose of shaking the cradle body 1 up and down.

Since the above-mentioned elastic support mechanism is used to replace the original suspension structure, the baby in the cradle body 1 can be effectively prevented from being pinched by the spring 6 . It can be seen from FIG. 3 that the spring 6 is completely located in the support protection sleeve 4, so the safety performance is greatly improved. Since the friction between the spring 6 and other components is effectively avoided, the service life of the spring 6 and other components is significantly prolonged, which greatly reduces maintenance and use costs. The improved structure reduces the consumption of materials and the space occupied by the baby cradle, thus effectively reducing the production cost, and the baby cradle is lighter and smaller, more convenient to move, and easier to place and store.
