Electric rockers effectively soothe infants, helping them enter deep sleep more quickly, thus reducing crying and providing a sense of security and comfort during the rocking process.

[0003] Existing electric cradles typically consist of a cradle and support legs to support the overall structure and enable the rocking function. However, the height between the cradle and the support legs is often not adjustable, making it difficult for users to flexibly adjust the height of the cradle according to the actual usage scenario. This results in the need to frequently bend over or lift the baby when picking them up or putting them down, which is inconvenient and affects the user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing electric baby cradles mentioned above typically consist of a cradle and supporting legs to support the overall structure and achieve the rocking function. However, the height between the cradle and the supporting legs is often not adjustable, making it difficult for users to flexibly adjust the height of the cradle according to actual usage scenarios. This results in frequent bending or lifting when holding or placing the baby, causing inconvenience in operation. The technical solution adopted by this utility model to solve this problem is: A height adjustment mechanism for an electric rocker bed includes a rocker bed support, a support leg, and a height adjustment assembly disposed between the rocker bed support and the support leg. The height adjustment assembly includes a slide mechanism connected to the rocker bed support and a locking mechanism connected to the support leg. The slide mechanism includes a plurality of locking grooves spaced apart in a vertical direction. The locking mechanism engages with the locking grooves to adjust the height of the rocker bed support relative to the support leg.

[0006] Furthermore, the slide mechanism includes an inner sleeve and an outer sleeve fitted on the outer wall of the inner sleeve. The inner sleeve can move vertically relative to the outer sleeve. The outer wall of the outer sleeve is provided with a baffle portion and an opening portion.

[0007] Furthermore, the locking mechanism includes a locking mounting seat sleeved on the outer wall of the outer sleeve, a locking tongue block hinged in the locking mounting seat, and a first spring member arranged in the horizontal direction. The locking tongue block passes through the opening and engages with the locking groove under the elastic force of the first spring member. One side of the first spring member abuts against the inner wall of the locking mounting seat, and the other side of the first spring member abuts against the locking tongue block.

[0008] Furthermore, the shaker support is provided with a first connecting hole, the outer sleeve is provided with a second connecting hole, and the inner sleeve is provided with a third connecting hole. The third connecting hole is arranged vertically and is elongated. A connector is provided between the first connecting hole, the second connecting hole, and the third connecting hole. The inner sleeve is provided with a second spring member arranged vertically at the end near the third connecting hole. One side of the second spring member abuts against the inner sidewall of the inner sleeve, and the other side of the second spring member abuts against the connector, so that the inner sleeve can move vertically relative to the outer sleeve.

[0009] Furthermore, the locking mounting base is provided with a receiving groove extending in a horizontal direction, and a hinge shaft is provided in the receiving groove. The locking tongue block is hinged to the locking mounting base through the hinge shaft.

[0010] Furthermore, the locking groove includes a first inclined surface and a second inclined surface connected to the first inclined surface. The cross-section of the locking groove is "V" shaped. The locking tongue block includes a first abutting surface arranged in the horizontal direction and abutting against the first inclined surface, a second guide surface arranged in an inclined direction and adapted to the second inclined surface, and a third limiting surface located between the first abutting surface and the second guide surface and arranged in the vertical direction.

[0011] Furthermore, the locking mounting base is provided with a limiting groove that is arranged vertically and communicates with the receiving groove. The limiting groove is used to restrict the locking tongue block from rotating around the hinge axis in a preset plane.

[0012] Furthermore, the first inclined surface and the second inclined surface are inclinedly connected and have rounded corners, and the two sides of the third limiting surface are inclinedly connected to the first abutting surface and the second guiding surface respectively and have rounded corners.

[0013] Furthermore, the number of locking grooves is the same as the number of openings, and the locking grooves and openings are arranged in a one-to-one correspondence in the vertical direction.

[0014] Furthermore, the locking mounting base is provided with a mounting groove for mounting the first spring member, and the mounting groove extends along the length direction of the first spring member.

[0015] The beneficial effects of this utility model are as follows: This invention features a sliding mechanism connected to the rocker frame and a locking mechanism connected to the support legs.

By engaging the locking mechanism with the locking slots at different heights, users can flexibly adjust the height of the rocker frame relative to the support legs according to the actual usage scenario, eliminating the need for frequent bending or lifting. This improves operational convenience and effectively solves the problem that existing electric rockers typically have a rocker and support legs to support the overall structure and achieve the rocking function. However, the height between the rocker and the support legs is often not adjustable, making it difficult for users to flexibly adjust the height of the rocker according to the actual usage scenario, resulting in frequent bending or lifting when holding or placing the baby, which is inconvenient.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 11 The height adjustment mechanism shown includes a rocking table support 1, a support leg 2, and a height adjustment assembly disposed between the rocking table support 1 and the support leg 2. The height adjustment assembly includes a slide mechanism 3 connected to the rocking table support 1 and a locking mechanism 4 connected to the support leg 2. The slide mechanism 3 includes a plurality of locking grooves 30 spaced apart in the vertical direction. The locking mechanism 4 is inserted into the locking grooves 30 to adjust the height of the rocking table support 1 relative to the support leg 2. This invention features a sliding mechanism connected to the rocker frame and a locking mechanism connected to the support legs. The sliding mechanism includes several locking slots spaced vertically. By engaging the locking mechanism with the locking slots at different heights, users can flexibly adjust the height of the rocker frame relative to the support legs according to the actual usage scenario, eliminating the need for frequent bending or lifting. This improves operational convenience and effectively solves the problem that existing electric rockers typically have a rocker and support legs to support the overall structure and achieve the rocking function. However, the height between the rocker and the support legs is often not adjustable, making it difficult for users to flexibly adjust the height of the rocker according to the actual usage scenario, resulting in frequent bending or lifting when holding or placing the baby, which is inconvenient.

[0020] Furthermore, the locking mechanism 4 and the locking groove 30 are designed to ensure stability after height adjustment, avoid safety hazards to the baby caused by the shaking of the rocking crib support 1 or height instability, and help provide the baby with a safe and comfortable sleeping environment.

[0021] Optionally, in some embodiments, the slide mechanism 3 includes a rack arranged vertically, the back of which is connected to the rocker support 1, and the front of which is provided with a plurality of locking grooves 30 spaced apart along the height direction. The locking grooves 30 can be rectangular notches or trapezoidal grooves, thereby providing multiple locking positions for height adjustment. The locking mechanism 4 includes a mounting housing mounted on the support bracket 2, a locking pin disposed in the mounting housing and slidable in the horizontal direction, a return spring for resetting, and a push button exposed in the mounting housing. Under normal conditions, the locking pin is engaged by the elastic action of the return spring. When the force is applied, the pin extends into the locking groove of the rack, thereby locking the height of the rocking table bracket 1 and the support leg 2. When the user needs to adjust the height, press the exposed button. Pressing the button causes the locking pin to retract horizontally against the spring force of the return spring, disengaging from the current locking groove 30 on the rack. Then, move the rocking table bracket 1 up and down, so that the rack moves synchronously with the rocking table bracket 1 until the target height is reached. At this time, release the button, the return spring returns to its deformation and pushes the locking pin to extend horizontally, re-inserting into the locking groove 30 of the rack at the corresponding height, thereby achieving quick positioning and locking of the rocking table height.

[0022] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the slide mechanism 3 includes an inner sleeve 31 and an outer sleeve 32. The outer sleeve 32 is fixed to the rocking bed support 1. The inner sleeve 31 is located inside the outer sleeve 32 and can move vertically relative to the outer sleeve 32 and the rocking bed support 1. The outer wall of the inner sleeve 31 is provided with locking grooves 30 spaced apart vertically. The outer wall of the outer sleeve 32 is provided with an opening 322 and a baffle 321. Multiple baffles 321 and openings 322 are provided and are alternately connected along the height of the outer sleeve 32. The locking mechanism 4 includes a locking mounting base 41 fixed to the support leg 2, a locking tongue block 42 hinged in the locking mounting base 41, and a first spring member 43 arranged horizontally. Under the thrust of the first spring member 43, the locking tongue block 42 can pass through the opening 322 on the outer sleeve 32 and extend into the locking groove 30.

[0023] Furthermore, the support frame 2 is equipped with a rocking motor for driving the rocking table bracket 1 to swing. The support frame 2 includes a first housing that is fixedly installed, and a second housing that is connected to the first housing and the rocking table bracket 1 respectively. The rocking motor is installed in the first housing, and the output shaft of the rocking motor is connected to the transmission mechanism or the rocking table bracket 1 in the second housing. Through the reciprocating rotation or eccentric rotation of the output shaft of the rocking motor, the second housing and the rocking table bracket 1 connected thereto are driven to achieve a smooth rocking motion.

[0024] like Figures 1 to 11 The slide mechanism 3 shown includes an inner sleeve 31 and an outer sleeve 32 sleeved on the outer wall of the inner sleeve 31. The inner sleeve 31 can move vertically relative to the outer sleeve 32. The outer wall of the outer sleeve 32 is provided with a baffle portion 321 and an opening portion 322. Multiple baffle portions 321 and opening portions 322 are provided and are alternately connected along the height direction of the outer sleeve 32. A plurality of locking grooves 30 are spaced apart along the height direction of the inner sleeve 31. Furthermore, the inner sleeve 31 and the outer sleeve 32 adopt a nested structure to form a double support, which is more resistant to the lateral sway of the rocker bracket 1 than a single slide structure, and helps to avoid deviation during height adjustment. Secondly, the outer sleeve 32 can cover most of the area of ​​the inner sleeve 31, which helps to reduce dust and debris from entering the slide, reduce component wear, and effectively extend the service life of the slide mechanism 3.

[0025] Furthermore, when the locking groove 30 is aligned with the opening 322, the locking tongue block 42 of the locking mechanism 4 can pass through the opening 322 and insert into the locking groove 30 to achieve rigid locking; while when the inner sleeve 31 is pulled up to the point where the locking groove 30 is aligned with the baffle 321, the baffle 321 blocks the locking tongue block 42 from entering, thereby unlocking; the baffle 321 and the opening 322 are alternately arranged to effectively prevent accidental locking or slippage, which is conducive to ensuring safe use.

[0026] Furthermore, the sleeve structure of the inner sleeve 31 and the outer sleeve 32, as well as the alternating arrangement of the baffle part 321 and the opening part 322, ensure that the entire slide mechanism 3 maintains the compactness and stability of the structure while providing height adjustment function, and avoids shaking or instability caused by height adjustment.

[0027] like Figures 1 to 11 The locking mechanism 4 shown includes a locking mounting base 41 sleeved on the outer wall of the outer sleeve 32, a locking tongue block 42 hinged in the locking mounting base 41, and a first spring member 43 arranged in the horizontal direction. The locking tongue block 42 passes through the opening 322 under the elastic force of the first spring member 43 and is inserted into the locking groove 30. One side of the first spring member 43 abuts against the inner side wall of the locking mounting base 41, and the other side of the first spring member 43 abuts against the locking tongue block 42. Furthermore, the first spring 43 abuts against the inner wall of the locking mounting base 41 and the locking tongue block 42 on both sides, which helps to continuously provide a stable lateral elastic force to the locking tongue block 42, ensuring that the locking tongue block 42 is tightly inserted into the locking groove 30, and avoiding loosening of the lock due to the swing of the rocker or slight collision. Secondly, the locking tongue block 42 is installed in the locking mounting base 41 by means of hinge, and the movement trajectory is fixed, which helps to accurately align the opening 322 of the outer sleeve 32 with the locking groove 30 of the inner sleeve 31, further ensuring the reliability of the lock and effectively reducing the safety risks during use.

[0028] Furthermore, the locking mechanism 4 drives the locking tongue block 42 to automatically reset through the elastic force of the first spring 43, and can maintain the insertion and engagement with the locking groove 30 under normal conditions without the need for additional manual fixing; when the user needs to adjust the height, the locking tongue block 42 is subjected to external force and overcomes the elastic force of the first spring 43, and the locking tongue block 42 disengages from the locking groove 30. After the rocker support 1 moves to the target height, the locking tongue block 42 will automatically pass through the opening 322 and insert into the corresponding locking groove 30 under the action of the first spring 43. The whole process does not require additional tools, which helps to improve the convenience of daily use.

[0029] Furthermore, when the user pulls the inner sleeve 31 upward, the inner sleeve 31 drives the locking groove 30 to move upward synchronously. The side wall of the locking groove 30 will exert an upward force on the locking tongue block 42, causing the locking tongue block 42 to flip away from the locking groove 30 around its hinge point with the locking mounting base 41. During this process, the locking tongue block 42 will squeeze the first spring member 43, causing the first spring member 43 to compress in the horizontal direction. As the inner sleeve 31 continues to move upward, the locking groove 30, which was originally aligned with the opening 322 of the outer sleeve 32, gradually shifts away from the opening 322 and eventually becomes aligned with the baffle part 321. At this time, the locking tongue block 42 completely disengages from the locking groove 30, and the height adjustment mechanism achieves smooth unlocking.

[0030] like Figures 1 to 11 The shaker bracket 1 shown is provided with a first connecting hole 11, the outer sleeve 32 is provided with a second connecting hole 323, and the inner sleeve 31 is provided with a third connecting hole 311. The third connecting hole 311 is arranged vertically and is elongated. A connector is provided between the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311. The inner sleeve 31 is provided with a second spring member 312 arranged vertically at the end near the third connecting hole 311. One side of the second spring member 312 abuts against the inner sidewall of the inner sleeve 31, and the other side of the second spring member 312 abuts against the connector, so that the inner sleeve 31 can move vertically relative to the outer sleeve 32. Furthermore, the elongated third connecting hole 311 allows the inner sleeve 31 to move vertically relative to the connector, that is, the inner sleeve 31 can move vertically relative to the outer sleeve 31. One end of the second spring 312 abuts against the inner wall of the inner sleeve 31, and the other end of the second spring 312 abuts against the connector. When the inner sleeve 31 is pulled up, it is compressed and stored energy. After releasing, the inner sleeve 31 is driven downward by the elastic force to reset, so that the locking groove 30 automatically aligns with the opening 322, thereby realizing the convenient operation of "pulling-releasing-automatic locking".

[0031] Specifically, the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311 are simultaneously connected to the connector, making the rocking bed bracket 1, the inner sleeve 31, and the outer sleeve 32 form a whole. Under normal conditions, the locking groove 30 of the inner sleeve 31 is aligned with the opening 322 on the outer sleeve 32. When the user needs to adjust the height, the inner sleeve 31 is pulled upward. At this time, the rocking bed bracket 1 and the outer sleeve 32 remain stationary because the first connecting hole 11 and the second connecting hole 323 are simultaneously fixed with the connector. Only the inner sleeve 31 can move vertically relative to the outer sleeve 32 and the rocking bed bracket 1 by means of the elongated third connecting hole 311. During the movement, the second spring 312 is compressed, and the locking groove 30, which was originally aligned with the opening 322 of the outer sleeve 32, gradually shifts away. The opening 322 is aligned with the baffle 321, and the lower end of the third connecting hole 311 abuts against the connector. At this time, the user can simultaneously move the rocking bed bracket 1, the inner sleeve 31, and the outer sleeve 32 to adjust the height. Because the locking groove 30 is aligned with the baffle 321, the locking tongue block 42 cannot extend into the locking groove 30. When the adjustment is in the appropriate position, the user releases the inner sleeve 31, and the second spring 312 restores its elastic deformation, pushing the inner sleeve 31 to move and reset relative to the outer sleeve 32 and the rocking bed bracket 1 in the vertical direction until the connector abuts against the upper end of the third connecting hole 311. At this time, the locking groove 30, which is aligned with the baffle 321, is aligned with the opening 322 again, and the locking tongue block 42 can pass through the opening 322 and extend into the locking groove 30 to complete the height locking.

[0032] Optionally, in some embodiments, the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311 are aligned, and the connector is a cylindrical pin. The pin passes through the second connecting hole 323 of the outer sleeve 32, the first connecting hole 11 of the rocking bed bracket 1, and the elongated third connecting hole 311 of the inner sleeve 31 in sequence. The two ends of the pin may be provided with snap rings or flared structures to prevent the pin from coming out during use. Since the third connecting hole 311 is vertically elongated, the inner sleeve 31 can move vertically on the pin 5, while the rocking bed bracket 1 and the outer sleeve 32 are fixed by the pin 5 due to the round hole fit and cannot move relative to each other. One end of the second spring 312 abuts against the inner wall of the inner sleeve 31, and the other end abuts against the pin.

[0033] Optionally, in some embodiments, the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311 are aligned, and the connecting member is a bolt with a nut. The bolt passes through the second connecting hole 323 of the outer sleeve 32, the first connecting hole 11 of the rocking bed bracket 1, and the elongated third connecting hole 311 of the inner sleeve 31 in sequence. The end of the bolt is locked by a nut. Because the third connecting hole 311 is elongated, the inner sleeve 31 can move vertically on the bolt. The rocking bed bracket 1 and the outer sleeve 32 are rigidly connected by the bolt 6. One end of the second spring member 312 abuts against the inner wall of the inner sleeve 31, and the other end abuts against the rod of the bolt 6.

[0034] like Figures 1 to 11 The locking mounting base 41 shown is provided with a receiving groove 411 extending in the horizontal direction. The receiving groove 411 is provided with a hinge shaft 412. The locking tongue block 42 is hinged to the locking mounting base 41 through the hinge shaft 412. Furthermore, the hinge shaft 412 is fixed in the receiving groove 411, providing a fixed rotation center for the locking tongue block 42, so that the locking tongue block 42 can only rotate around the hinge shaft 412, and the movement trajectory is precise and controllable, avoiding the problem of failure to insert smoothly or loose locking due to the offset of the locking tongue block 42.

[0035] Furthermore, the hinge shaft 412 is set in the horizontal direction, so that the locking tongue block 42 can reliably rotate around the hinge shaft 412 in the vertical plane, with a clear movement trajectory, avoiding skew or jamming, which helps to ensure that the locking tongue block 42 smoothly exits the locking groove 30 when unlocking and accurately inserts when locking.

[0036] Furthermore, the receiving groove 411 is integrally formed inside the locking mounting base 41, and the hinge shaft 412 can be directly embedded or fixed in the receiving groove 411. After the locking tongue block 42 is installed from the side or end, it is sleeved on the hinge shaft 412. No additional fasteners are required, which helps to simplify the assembly process and reduce manufacturing costs.

[0037] Furthermore, the hinge shaft 412 and the locking tongue block 42 are located inside the locking mounting base 41, which effectively prevents dust and foreign objects from entering the hinge area, which helps to reduce wear and improve the reliability and lifespan of long-term use.

[0038] like Figures 1 to 11 The locking groove 30 shown includes a first inclined surface 301 and a second inclined surface 302 connected to the first inclined surface 301. The cross-section of the locking groove 30 is "V" shaped. The locking tongue block 42 includes a first abutting surface 421 arranged horizontally and abutting against the first inclined surface 301, a second guide surface 422 arranged inclined and adapted to the second inclined surface 302, and a third limiting surface 423 located between the first abutting surface 421 and the second guide surface 422 and arranged vertically. Specifically, when the user pulls the inner sleeve 31 upward, the locking groove 30 moves upward synchronously with the inner sleeve 31. At this time, the second inclined surface 302 of the locking groove 30 will form an inclined engagement with the second guide surface 422 of the locking tongue block 42. Due to the upward pulling force of the inner sleeve 31, the second inclined surface 302 will generate an oblique pushing force on the second guide surface 422. This pushing force can be decomposed into a component force that drives the locking tongue block 42 to rotate around the hinge axis 412.

[0039] Furthermore, when the locking tongue block 42 is fully inserted, the first horizontal abutting surface 421 of the locking tongue block 42 abuts against the first inclined surface 301 of the locking groove 30, which can effectively withstand the vertical downward load generated when the rocker is working, prevent the locking tongue block 42 from being pressed out, and help ensure that the height is locked firmly and reliably.

[0040] Furthermore, the third limiting surface 423 is arranged vertically and located between the first abutting surface 421 and the second guide surface 422, which further restricts the position of the locking tongue block 42 in the locking groove 30, ensuring that the locking tongue block 42 will not move laterally in the locked state, which is beneficial to improving the reliability of locking.

[0041] like Figures 1 to 11 The locking mounting base 41 shown is provided with a limiting groove 413 arranged in the vertical direction and communicating with the receiving groove 411. The limiting groove 413 is used to restrict the locking tongue block 42 from rotating around the hinge axis 412 in a preset plane. Furthermore, the limiting groove 413 is arranged vertically and communicates with the receiving groove 411, which can limit the locking tongue block 42 from both sides in the vertical direction, forcing the locking tongue block 42 to only rotate around the hinge axis 412 in the preset vertical plane, so as to avoid the locking tongue block 42 from being deviated or tilted in the horizontal direction due to the swing of the rocker, vibration or external force.

[0042] Furthermore, the limiting groove 413 restricts the locking of the bolt block 42, allowing it to engage more accurately with the locking groove 30 when locked, which helps reduce locking failures caused by inaccurate positioning of the bolt block 42. When unlocking, the limiting groove 413 also ensures that the bolt block 42 can smoothly exit from the locking groove 30, avoiding unlocking difficulties caused by the bolt block 42 getting stuck or shifting.

[0043] like Figures 1 to 11 The first inclined surface 301 and the second inclined surface 302 shown are inclinedly connected and have rounded corners. The two sides of the third limiting surface 423 are inclinedly connected to the first abutting surface 421 and the second guiding surface 422 respectively and have rounded corners. Furthermore, the connection between the first inclined surface 301 and the second inclined surface 302, as well as the connection between the third limiting surface 423 and the first abutting surface 421 and the second guiding surface 422 respectively, are all rounded to avoid stress concentration caused by sharp edges, which helps to reduce the risk of cracks or plastic deformation under repeated insertion and removal and vibration loads, and effectively extends the service life of the mechanism.

[0044] Furthermore, during the process of the locking tongue block 42 inserting into or retracting from the locking groove 30, the rounded corner serves as a smooth transition area, which can guide the smooth sliding between the contact surfaces and avoid jamming, abnormal noise, or wear caused by the scraping of the sharp corners, making the height adjustment operation smoother.

[0045] Furthermore, the rounded corners play a guiding role in the initial contact stage. Even if there are slight assembly deviations or movement offsets between the locking tongue block 42 and the locking groove 30, the rounded corners can naturally guide them into the correct mating position, thereby improving the locking success rate.

[0046] like Figures 1 to 11 The number of locking grooves 30 shown is the same as the number of openings 322, and the locking grooves 30 and the openings 322 are arranged in a one-to-one correspondence in the vertical direction; Furthermore, the number of locking grooves 30 and openings 322 are the same and they correspond one-to-one in the vertical direction, so that each locking groove 30 can precisely cooperate with the locking tongue block 42 of the locking mechanism 4 through the corresponding opening 322, thereby forming a clear and fixed height adjustment position.

[0047] Furthermore, since the locking groove 30 and the opening 322 correspond one-to-one in the vertical direction, the locking tongue block 42 can be quickly and accurately inserted into the locking groove 30, which helps to reduce the time and operation steps required for locking. When unlocking, the locking tongue block 42 can quickly exit from the locking groove 30, making the unlocking process faster and effectively improving the efficiency of the entire height adjustment process.

[0048] like Figures 1 to 11The locking mounting base 41 shown is provided with a mounting groove 414 for mounting the first spring member 43, and the mounting groove 414 extends along the length direction of the first spring member 43. Furthermore, the mounting groove 414 extends along the length of the first spring member 43, which helps to constrain the movement trajectory of the first spring member 43 during compression or extension, prevents the first spring member 43 from bending, shifting or twisting laterally when subjected to force, and helps to ensure that the elastic force always acts stably on the locking tongue block 42 in the horizontal direction, effectively ensuring the reliability of locking and unlocking actions.

[0049] Furthermore, the mounting slot 414 provides a preset mounting space for the first spring component 43. During assembly, the first spring component 43 can be directly placed in the mounting slot 414, and then the locking tongue block 42 can be installed without additional positioning fixtures or complex adjustments, which is conducive to improving production efficiency and reducing assembly errors.

[0050] Furthermore, the first spring member 43 is confined within the mounting groove 414, which helps to avoid unexpected friction or collision with the inner wall of the locking mounting base 41 or other components, helps to reduce wear and fatigue damage, effectively extends the service life of the first spring member 43, and reduces the risk that the locking tongue block 42 cannot be reset due to the failure of the first spring member 43.

[0051] The working principle is as follows: Under normal conditions, the locking tongue block 42 is hinged to the receiving groove 411 of the locking mounting base 41 via the hinge shaft 412, and the limiting groove 413 limits the movement of the locking tongue block 42 in the vertical plane; the first spring member 43 is installed in the mounting groove 414 extending along its length direction, one side of the first spring member 43 abuts against the inner sidewall of the locking mounting base 41, and the other side of the first spring member 43 abuts against the locking tongue block 42. The first spring member 43 is in a naturally extended state, pushing the locking tongue block 42 through the opening 322 of the outer sleeve 32 and engaging with the locking groove 30 of the inner sleeve 31. The locking groove 30 and the opening 322 correspond one-to-one in the vertical direction. At the same time, the second connecting hole 323 of the outer sleeve 32, the first connecting hole 11 of the rocking bed bracket 1, and the elongated third connecting hole 311 of the inner sleeve 31 are connected by a connector. The second spring member 312 of the inner sleeve 31 is in a naturally extended state, forming a stable high-locking structure. When the user needs to adjust the height, the inner sleeve 31 is pulled upwards. At this time, the rocking bed bracket 1 and the outer sleeve 32 remain stationary because the first connecting hole 11 and the second connecting hole 323 are synchronously fixed with the connector. Only the inner sleeve 31 can move vertically relative to the outer sleeve 32 and the rocking bed bracket 1 through the elongated third connecting hole 311. The inner sleeve 31 drives the locking groove 30 to move upwards synchronously. The second inclined surface 302 of the locking groove 30 cooperates with the inclined surface of the second guide surface 422 of the locking tongue block 42, pushing the locking tongue block 42 around... The hinge shaft 412 flips away from the locking groove 30. At this time, the first spring 43 is compressed by the locking tongue block 42 in the mounting groove 414. As the inner sleeve 31 moves up, the second spring 312 is also gradually compressed by the connecting piece. The locking groove 30 gradually shifts away from the opening 322 and aligns with the baffle 321 of the outer sleeve 32. The locking tongue block 42 cannot extend into the locking groove 30 because of the baffle 321. At this time, the user can move the rocking bed bracket 1, the inner sleeve 31 and the outer sleeve 32 at the same time to adjust the height. After adjusting to the appropriate height, the user releases the inner sleeve 31, and the second spring 312 returns to its elastic deformation, pushing the inner sleeve 31 to move vertically relative to the outer sleeve 32 and the rocker bracket 1 until the connector abuts against the upper end of the third connecting hole 311; at the same time, the first spring 43 extends in the mounting groove 414, pushing the locking tongue block 42 to flip in the opposite direction. When the locking groove 30 of the inner sleeve 31 is vertically aligned with the opening 322 of the outer sleeve 32 again, the locking tongue block 42 passes through the opening 322 and re-inserts into the locking groove 30. The first spring 43 returns to its natural extended state, and the second spring 312 also returns to its natural extended state, thus completing the height locking.

[0052] The implementation method of Example 1 is as follows: A height adjustment mechanism for an electric rocker includes a rocker support 1, a support leg 2, and a height adjustment assembly disposed between the rocker support 1 and the support leg 2. The height adjustment assembly includes a slide mechanism 3 connected to the rocker support 1 and a locking mechanism 4 connected to the support leg 2. The slide mechanism 3 includes a plurality of locking grooves 30 spaced apart in the vertical direction. The locking mechanism 4 is engaged with the locking grooves 30 to adjust the height of the rocker support 1 relative to the support leg 2.

[0053] This invention features a sliding mechanism connected to the rocker frame and a locking mechanism connected to the support legs. The sliding mechanism includes several locking slots spaced vertically. By engaging the locking mechanism with the locking slots at different heights, users can flexibly adjust the height of the rocker frame relative to the support legs according to the actual usage scenario, eliminating the need for frequent bending or lifting. This improves operational convenience and effectively solves the problem that existing electric rockers typically have a rocker and support legs to support the overall structure and achieve the rocking function. However, the height between the rocker and the support legs is often not adjustable, making it difficult for users to flexibly adjust the height of the rocker according to the actual usage scenario, resulting in frequent bending or lifting when holding or placing the baby, which is inconvenient.

[0054] The implementation method of Example 2 is as follows: Based on Embodiment 1, Embodiment 2 further includes the following implementation: The slide mechanism 3 includes an inner sleeve 31 and an outer sleeve 32 sleeved on the outer wall of the inner sleeve 31. The inner sleeve 31 can move vertically relative to the outer sleeve 32. The outer wall of the outer sleeve 32 is provided with a baffle portion 321 and an opening portion 322. Multiple baffle portions 321 and opening portions 322 are provided and are alternately connected along the height direction of the outer sleeve 32. Several locking grooves 30 are spaced apart along the height direction of the inner sleeve 31.

[0055] The implementation method of Example 3 is as follows: Based on Embodiment 2, Embodiment 3 further includes the following implementation: The locking mechanism 4 includes a locking mounting base 41 sleeved on the outer wall of the outer sleeve 32, a locking tongue block 42 hinged in the locking mounting base 41, and a first spring member 43 arranged in the horizontal direction. The locking tongue block 42 passes through the opening 322 under the elastic force of the first spring member 43 and is inserted into the locking groove 30. One side of the first spring member 43 abuts against the inner side wall of the locking mounting base 41, and the other side of the first spring member 43 abuts against the locking tongue block 42.

[0056] The implementation method of Example 4 is as follows: Based on Embodiment 2, Embodiment 4 further includes the following implementation: The shaking table support 1 is provided with a first connecting hole 11, the outer sleeve 32 is provided with a second connecting hole 323, and the inner sleeve 31 is provided with a third connecting hole 311. The third connecting hole 311 is arranged vertically and is elongated. A connector is provided between the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311. The inner sleeve 31 is provided with a second spring member 312 arranged vertically at the end near the third connecting hole 311. One side of the second spring member 312 abuts against the inner sidewall of the inner sleeve 31, and the other side of the second spring member 312 abuts against the connector, so that the inner sleeve 31 can move vertically relative to the outer sleeve 32.

[0057] The implementation method of Example 5 is as follows: Based on Embodiment 3, Embodiment 5 also has the following implementation method: The locking mounting base 41 is provided with a receiving groove 411 extending in the horizontal direction, and a hinge shaft 412 is provided in the receiving groove 411. The locking tongue block 42 is hinged to the locking mounting base 41 through the hinge shaft 412.

[0058] The implementation method of Example 6 is as follows: Based on Embodiment 3, Embodiment 6 further includes the following implementation: The locking groove 30 includes a first inclined surface 301 and a second inclined surface 302 connected to the first inclined surface 301. The cross-section of the locking groove 30 is "V" shaped. The locking tongue block 42 includes a first abutting surface 421 arranged horizontally and abutting against the first inclined surface 301, a second guide surface 422 arranged inclinedly and adapted to the second inclined surface 302, and a third limiting surface 423 located between the first abutting surface 421 and the second guide surface 422 and arranged vertically.

[0059] The implementation method of Example 7 is as follows: Based on Embodiment 5, Embodiment 7 also has the following implementation method: The locking mounting base 41 is provided with a limiting groove 413 that is arranged in the vertical direction and communicates with the receiving groove 411. The limiting groove 413 is used to restrict the locking tongue block 42 from rotating around the hinge axis 412 in a preset plane.

[0060] The implementation method of Example 8 is as follows: Based on Embodiment 6, Embodiment 8 further includes the following implementation: the first inclined surface 301 and the second inclined surface 302 are inclinedly connected and have rounded corners, and the two sides of the third limiting surface 423 are inclinedly connected to the first abutting surface 421 and the second guiding surface 422 respectively and have rounded corners.

[0061] The implementation method of Example 9 is as follows: Based on Embodiment 2, Embodiment 9 also has the following implementation method: the number of locking grooves 30 is the same as the number of openings 322, and the locking grooves 30 and openings 322 are arranged in a one-to-one correspondence in the vertical direction.

[0062] The implementation method of Example 10 is as follows: Based on Embodiment 3, Embodiment 10 also has the following implementation method: The locking mounting base 41 is provided with a mounting groove 414 for mounting the first spring member 43, and the mounting groove 414 extends along the length direction of the first spring member 43.

[0063] The implementation method of Example 11 is as follows: Example 11, based on Example 1, further includes the following implementation: The slide mechanism 3 includes a rack arranged vertically, the back of which is connected to the rocker support 1. The front of the rack has multiple locking grooves 30 spaced apart along the height direction. The locking grooves 30 can be rectangular notches or trapezoidal grooves, thereby providing multiple locking positions for height adjustment. The locking mechanism 4 includes a mounting housing mounted on the support bracket 2, a locking pin located inside the mounting housing and slidable horizontally, a reset spring for resetting, and a push button exposed outside the mounting housing. Under normal conditions, the locking pin resets... The spring's elastic force causes it to extend into the locking groove of the rack, thus locking the height of the rocking table bracket 1 and the support leg 2. When the user needs to adjust the height, pressing the exposed button causes the locking pin to retract horizontally against the spring force of the return spring, disengaging it from the current locking groove 30 on the rack. Then, the rocking table bracket 1 is moved up and down, causing the rack to move synchronously with the rocking table bracket 1 until the target height is reached. At this point, releasing the button restores the return spring's deformation and pushes the locking pin to extend horizontally, re-inserting it into the corresponding locking groove 30 on the rack, thus achieving rapid positioning and locking of the rocking table height.

[0064] The implementation method of Example Twelve is as follows: Based on Example 4, Example 12 further includes the following implementation: The first connecting hole 11, the second connecting hole 323, and the third connecting hole 311 are aligned. The connecting element is a cylindrical pin. The pin passes through the second connecting hole 323 of the outer sleeve 32, the first connecting hole 11 of the rocking bed bracket 1, and the elongated third connecting hole 311 of the inner sleeve 31 in sequence. The two ends of the pin can be provided with snap rings or flared structures to prevent the pin from coming out during use. Since the third connecting hole 311 is a vertical elongated shape, the inner sleeve 31 can move vertically on the pin 5. The rocking bed bracket 1 and the outer sleeve 32 are fixed by the pin 5 due to the round hole fit and cannot move relative to each other. One end of the second spring 312 abuts against the inner wall of the inner sleeve 31, and the other end abuts against the pin.

[0065] The implementation method of Example Thirteen is as follows: The difference between Embodiment Thirteen and Embodiment Twelve is that the first connecting hole 11, the second connecting hole 323, and the third connecting hole 311 are aligned, and the connecting member is a bolt with a nut. The bolt passes through the second connecting hole 323 of the outer sleeve 32, the first connecting hole 11 of the rocking bed bracket 1, and the elongated third connecting hole 311 of the inner sleeve 31 in sequence. The end of the bolt is locked by a nut. Because the third connecting hole 311 is elongated, the inner sleeve 31 can move vertically on the bolt. The rocking bed bracket 1 and the outer sleeve 32 are rigidly connected by the bolt 6. One end of the second spring member 312 abuts against the inner wall of the inner sleeve 31, and the other end abuts against the rod of the bolt 6.
