Description

Technical Field

[0001] This utility model relates to the field of medical and health care device technology, specifically a portable lumbar support frame. Background Technology

[0002] Lumbar spine diseases can cause symptoms such as lower back pain, leg pain, leg swelling, soreness, numbness, intermittent claudication, sciatica, muscle atrophy, and even urinary and fecal incontinence, which seriously affect patients' quality of life and work ability. Therefore, through in-depth research on the structure and biomechanical principles of the human lumbar spine, ergonomic principles are applied to the design of lumbar spine support frames, so that they can better conform to the curve of the human lumbar spine, provide more uniform and effective support, and reduce lumbar spine pressure.

[0003] Chinese patent CN102512010A discloses a lumbar support cushion with a curved upper central part corresponding to the shape of the pelvis. The upper rear part is equipped with a fixed frame and includes a support for the lumbar spine. The upper part of this lumbar support cushion is curved to correspond to the curvature of the pelvis, thus supporting the pelvis. The lumbar support ensures the stability of the lumbar spine and also ensures correct sitting posture. Therefore, by maintaining the correct sitting posture, even sitting for a long time will not induce lumbar spine disease and pain.

[0004] According to the aforementioned existing technology, in daily use, due to the wide variety of common chair types and specifications, the specifications of lumbar support frames are usually not adjustable and fixed to the chair according to the chair specifications. When leaning against the chair in different postures, the lumbar support frame will shift and fall off the chair. In addition, common lumbar support frames are large in size and not easy to store, which makes it impossible to frequently carry them to various environments to support and protect the lumbar spine.

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, this utility model provides a portable lumbar support frame to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a portable lumbar support frame, comprising a support plate, an adjustment block movably provided on the surface of the support plate, a telescopic rod provided inside the adjustment block, and a fitting plate movably provided at the end of the telescopic rod away from the adjustment block, the fitting plate being arc-shaped, and the support plate providing support and protection for the lumbar region through the fitting plate;

The outer surface of the ball joint is provided with a limiting ring, and the end of the limiting ring facing the bonding plate is provided with a return spring. The other end of the return spring is connected to one side of the bonding plate.

[0010] Preferably, when the bonding plate is under pressure, the bonding plate deflects in the direction of pressure, and the return spring is in a stretched state;

[0011] When the bonding plate is not under pressure, the bonding plate gradually deflects in the initial direction, and the return spring is in a contracted state.

[0012] Preferably, the support plate is provided with a first electrically controlled slide rail on the side near the adjusting block for longitudinal sliding of the adjusting block;

[0013] The surface of the support plate is provided with a fixing block, and one side of the fixing block is provided with a fastening strap. The number of fixing blocks and fastening straps is set to two. Each fixing block and fastening strap is symmetrically distributed on the surface of the support plate. The ends of the two fastening straps away from the fixing blocks are respectively provided with pins and holes. The pins and holes are compatible with each other. The support plate is fixed by the two symmetrically arranged fastening straps.

[0014] Preferably, a rotary motor is provided on one side of the inner wall of the adjusting block, and the output end of the rotary motor is connected to the telescopic rod. The rotary motor is used to control the rotation of the telescopic rod, the ball joint, and the bonding plate.

[0015] The number of each of the adjusting block, rotary motor, telescopic rod, ball joint, return spring, and bonding plate is two, and each of the adjusting block, rotary motor, telescopic rod, ball joint, return spring, and bonding plate is symmetrically arranged on the surface of the support plate.

[0016] Preferably, an electronic spring is provided on the outer surface of the telescopic rod, the electronic spring being used to control the telescopic rod to extend or retract, and the electronic spring being located on the outer surface of the telescopic rod near the adjusting block;

[0017] When the electronic spring is energized, it extends towards the bonding plate, while the telescopic rod is extended and the bonding plate extends away from the adjusting block.

[0018] When the electronic spring is de-energized, it retracts towards the adjusting plate, the telescopic rod is in a retracted state, and the bonding plate retracts towards the adjusting plate.

[0019] Preferably, the back of the support plate is provided with a second electrically controlled slide rail, and two symmetrically arranged fixed sliders are slidably provided on the outer surface of the second electrically controlled slide rail. The fixed sliders move laterally along the support plate through the second electrically controlled slide rail. The back of the support plate is provided with a control panel.

[0020] The fixed slider has a compression spring inside, and the other end of the compression spring has a limiting slider on one side. The limiting slider has a clamping member on the other side. The clamping member is L-shaped and slides inside the fixed slider through the limiting slider.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a portable lumbar support frame, which has the following advantages:

[0023] 1. This portable lumbar support frame uses two symmetrically arranged fixed sliders and two symmetrically arranged fastening straps on the support plate. The user stretches the fastening straps and wraps them around the back of the seat, making the support plate fit tightly against the seat back, thus achieving a fixing effect on the support plate. In addition, through the control panel and the second electrically controlled slide rail, the two symmetrically arranged fixed sliders move relative to each other on the surface of the second electrically controlled slide rail until they move to the left and right edges of the seat back. The two symmetrically arranged fixed sliders form a secondary fixing effect at the bottom of the support plate, thereby preventing displacement and detachment during use.

[0024] 2. This portable lumbar support frame incorporates a pressure sensor on the surface of the telescopic rod near the electronic spring. This sensor monitors the pressure on two symmetrically positioned contact plates in real time and adjusts the working state of the contact plates accordingly. This prevents damage to the contact plates caused by sudden high pressure. Furthermore, by detecting the pressure on the two contact plates, the frame reflects and determines whether the user's sitting posture is healthy. By adjusting the interaction between the telescopic rod and the contact plates, the frame improves the user's posture, preventing lumbar spine problems caused by incorrect posture.

[0025] 3. This portable lumbar support frame, by setting up a control panel and retracting two electronic springs, allows the side of the fitting plate facing the support plate to fit against the adjustment block, thereby shortening the space between the fitting plate and the support plate. At the same time, the user can shorten the distance between the fitting plate and the support plate by wrapping the fastening strap around the support plate in the opposite direction and fixing it through the pin and the hole, reducing the space occupied and making it easier to store. The fastening strap is also used to fix the fitting plate by wrapping it in reverse. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-9A portable lumbar support frame includes a support plate 2. An adjustment block 13 is movably provided on the surface of the support plate 2. A telescopic rod 10 is provided inside the adjustment block 13. A fitting plate 8 is movably provided at the end of the telescopic rod 10 away from the adjustment block 13. The fitting plate 8 is arc-shaped. The support plate 2 provides support and protection for the lumbar region through the fitting plate 8. A ball joint 9 for deflecting the fitting plate 8 is provided at the end of the telescopic rod 10 near the fitting plate 8. A limiting ring 17 is provided on the outer surface of the ball joint 9. A return spring 12 is provided at the end of the limiting ring facing the fitting plate 8. The other end of the return spring 12 is connected to one side of the fitting plate 8.

[0038] like Figure 1 As shown, the support plate 2 has a first electrically controlled slide rail 14 for longitudinal sliding of the adjusting block 13 on the side near the adjusting block 13. A fixing block 16 is provided on the surface of the support plate 2, and a fastening band 1 is provided on one side of the fixing block 16. The number of fixing blocks 16 and fastening bands 1 is two, and each fixing block 16 and fastening band 1 is symmetrically distributed on the surface of the support plate 2. The ends of the two fastening bands 1 away from the fixing block 16 are respectively provided with pins 3 and holes, which are mutually compatible. The support plate 2 is fixed by the two symmetrically arranged fastening bands 1. The back is provided with a second electrically controlled slide rail 15. Two symmetrically arranged fixed sliders 6 are slidably arranged on the outer surface of the second electrically controlled slide rail 15. The fixed sliders 6 move laterally along the support plate 2 via the second electrically controlled slide rail 15. The back of the support plate 2 is provided with a control panel 5. The fixed slider 6 is provided with a compression spring 702 inside. The other end of the compression spring 702 is provided with one side of a limiting slider 701. The other side of the limiting slider 701 is provided with a clamping member 7. The clamping member 7 is L-shaped and slides inside the fixed slider 6 via the limiting slider 701.

[0039] In use, the first electronically controlled slide rail 14 controls the adjusting block 13 to slide longitudinally along the support plate 2, thereby changing the height of the fitting plate 8. This not only adapts to various seat types but also to the back height of the users, thus increasing the applicability of the device. Secondly, the electronic spring 11 controls the telescopic rod 10 to extend or retract towards the fitting plate 8, thereby changing the distance between the fitting plate 8 and the support plate 2. This adapts to the sitting postures of people with different postures, achieving adaptation to the lumbar spine of different people, and better supporting and protecting the user's waist. Then, the symmetrically arranged fixed sliders 6 fix and clamp the left and right edges of the seat, thereby improving the stability of the support plate 2 during use and preventing the support plate 2 from shifting or falling off due to uneven force.

[0040] like Figure 4As shown, a rotary motor 4 is provided on one side of the inner wall of the adjusting block 13. The output end of the rotary motor 4 is connected to the telescopic rod 10. The rotary motor 4 is used to control the rotation of the telescopic rod 10, the ball joint 9 and the bonding plate 8. There are two of each of the adjusting block 13, rotary motor 4, telescopic rod 10, ball joint 9, return spring 12 and bonding plate 8. Each of the adjusting block 13, rotary motor 4, telescopic rod 10, ball joint 9, return spring 12 and bonding plate 8 is symmetrically arranged on the surface of the support plate 2.

[0041] In use, a rotary motor 4 is installed inside the adjusting block 13, and the rotary motor 4 is turned on to drive the telescopic rod 10 and control the telescopic rod 10 to rotate. This causes the fitting plate 8 to deflect in the direction of rotation of the rotary motor 4. In addition, by setting multiple adjusting blocks 13, rotary motor 4, telescopic rod 10, ball joint 9, return spring 12 and fitting plate 8, and using two symmetrically arranged fitting plates 8, the user's back is fully covered, avoiding gaps between the user's back and the seat, which would prevent the lumbar spine from being supported and protected, thus preventing lumbar lesions.

[0042] like Figure 5 As shown, an electronic spring 11 is provided on the outer surface of the telescopic rod 10. The electronic spring 11 is used to control the telescopic rod 10 to extend and retract. The electronic spring 11 is located on the outer surface of the telescopic rod 10 near the adjusting block 13. When the electronic spring 11 is energized, it extends towards the bonding plate 8, and the telescopic rod 10 is in an extended state. The bonding plate 8 extends away from the adjusting block 13. When the electronic spring 11 is de-energized, it retracts towards the adjusting plate, and the telescopic rod 10 is in a retracted state. The bonding plate 8 retracts towards the adjusting plate. When the bonding plate 8 is under pressure, it deflects in the direction of pressure, and the return spring 12 is in a stretched state. When the bonding plate 8 is not under pressure, it gradually deflects in the initial direction, and the return spring 12 is in a contracted state.

[0043] In use, an electronic spring 11 is installed on the outer surface of the telescopic rod 10 and activated, causing the electronic spring 11 to extend towards the bonding plate 8. This causes the telescopic rod 10 to extend towards the bonding plate 8 along with the electronic spring 11, thus adjusting the distance between the bonding plate 8 and the support plate 2. Secondly, when the user leans their back against the surface of the bonding plate 8, the bonding plate 8 deflects towards the area of ​​higher pressure through the ball joint 9. Subsequently, when the user's back is no longer in contact with the surface of the bonding plate 8 (the bonding plate 8 is not under stress), the return spring 12, in conjunction with the ball joint 9, returns the bonding plate 8 to its original state.

[0044] In summary, during use, first place the support plate 2 and the fitting plate 8 on the surface of the seat, so that the support plate 2 fits against the back of the seat. Then, through the control panel 5 on the back of the support plate 2, slide the two symmetrically arranged fixing sliders 6 on the surface of the second electric slide rail 15 (the two symmetrically arranged fixing sliders 6 slide relative to each other along the second electric slide rail 15). When the fixing sliders 6 are moved to the left and right edges of the backrest, they clamp and fix the left and right sides of the backrest. Then, the user needs to stretch the fastening strap 1 on the support plate 2 and cooperate with the pin 3 and the hole to make the upper area of ​​the support plate 2 fit against the backrest of the seat. Through the cooperation of the fastening strap 1 and the fixing sliders 6, the support plate 2 is fixed, avoiding the situation where the support plate 2 shifts or falls off due to uneven pressure caused by the user's sitting posture.

[0045] After the support plate 2 is fixed, the user simply needs to sit normally on the seat and lean against the surface of the mating plate 8 towards their lower back. This provides support and protection for the user's lumbar spine, preventing lumbar spine problems caused by prolonged sitting. Furthermore, if the user is tall and the position of the mating plate 8 does not correspond to their lumbar spine area, the user can adjust the position by using the control panel 5 on the back of the support plate 2 and the first electrically controlled slide rail 14 to move the adjustment block 13 longitudinally along the surface of the support plate 2. The adhesive plate 8 is adjusted according to the user's lumbar spine area until the area facing the adhesive plate 8 corresponds to the user's lumbar spine area. When it is necessary to adjust the distance between the adhesive plate 8 and the support plate 2, simply turn on the electronic spring 11 again through the control panel 5, so that the electronic spring 11 extends towards the adhesive plate 8, thereby controlling the extension rod 10 to extend towards the adhesive plate 8. At this time, the adhesive plate 8 moves towards the user's lumbar spine under the cooperation of the extension rod 10 and the electronic spring 11, so that the adhesive plate 8 can fully support and protect the user's lumbar spine.

[0046] When the user's lower back is fully in contact with the fitting plate 8, the fitting plate 8, in conjunction with the ball joint 9 and the return spring 12, will deflect towards the area of ​​higher pressure. This ensures that the fitting plate 8 can always support and protect the user's lumbar spine area when the user changes any sitting posture, preventing gaps when the user leans against it, which could lead to lumbar spine problems after prolonged sitting. In addition, when the user's lumbar spine is no longer in contact with the surface of the fitting plate 8, the return spring 12 will use its own elasticity to control the fitting plate 8 and the ball joint 9 to move back to their initial state, ultimately achieving the effect of the fitting plate 8 returning to its original position through the return spring 12.

[0047] When it is necessary to carry it, simply use the control panel 5 to retract the two electronic springs 11, so that the side of the bonding plate 8 facing the support plate 2 is in contact with the adjusting block 13, thereby shortening the space between the bonding plate 8 and the support plate 2. At the same time, the user can wrap the fastening strap 1 around the support plate 2 in the opposite direction and fix the bonding plate 8 by using the pin 3 and the hole. During this process, the electronic spring 11 is always in a retracted state and works with the fastening strap 1 to shorten the distance between the bonding plate 8 and the support plate 2, reducing the space occupied and making it easier to store. At the same time, the fastening strap 1 is used to fix the bonding plate 8 by reversing the wrapping.

[0048] Secondly, when different groups of people use the lumbar support frame, the pressure applied to the frame varies. If the pressure on the frame is too high and the force distribution is not adjusted in time, the frame may be damaged on the spot, posing a safety hazard to the user.

[0049] Therefore, during use, a pressure sensor is set at one end of the electronic spring 11 near the telescopic rod 10, and the pressure sensor detects the force on the bonding plate 8 in real time, and makes dynamic adjustments based on the force data on the two bonding plates 8, so as to avoid damage when one or two bonding plates 8 are subjected to high pressure. The two symmetrically arranged pressure sensors are respectively denoted as area A and area B, and correspond to the left bonding plate 8 and the right bonding plate 8.

[0050] When the pressure sensors in areas A and B detect pressure on the bonding plate 8, the pressure data detected in the two areas are compared. If the pressure data in both areas are within the preset value and the pressure data in the two areas are relatively uniform, it means that the user is in a leaning state and the user's leaning posture is normal. The two bonding plates 8 are also always in close contact with the user's back. Therefore, no adjustment is needed, and the pressure sensors in the two areas can continue to detect the force state of the two bonding plates 8 in real time.

[0051] If the pressure difference between area A and area B is too large, it indicates that the user's posture is tilted towards area A, resulting in higher pressure in area A than in area B. This posture can damage the user's lumbar spine and easily lead to lesions. In this case, the electronic spring 11 in area A is controlled by the control panel 5 to extend towards the bonding plate 8. At the same time, the telescopic rod 10 also moves towards the bonding plate 8, causing the bonding plate 8 in area A to push towards the user's lumbar spine. This makes the extension of the telescopic rod 10 and the bonding plate 8 in area A greater than that in area B. This pushes the side the user is leaning towards, thereby leveling the user's lumbar spine and changing the pressure distribution in the user's lower back. At the same time, the extension of the telescopic rod 10 and the bonding plate 8 in area A towards the user's lower back also reminds the user to change to a correct sitting and leaning posture, avoiding lumbar lesions caused by incorrect sitting or leaning posture.

[0052] It is worth noting that if the pressure data detected in area B is much higher than that in area A, it means that the user's leaning or sitting posture is tilted towards area B, and the adjustment method is the opposite of that described above.

[0053] If the pressure sensors in both areas are much higher than the preset values, it indicates that the user's weight has seriously exceeded the device's bearing capacity. At this time, the control panel 5 immediately causes the two electronic springs 11 to drive the telescopic rods 10 to retract towards the support plate 2. During this process, the two rotary motors 4 control the two bonding plates 8 to rotate relative to each other. When rotating, the two electronic springs 11 are used to control the two telescopic rods 10 to form a gap (equivalent to the contraction speed of area A being higher than that of area B). At this time, the rotary motors 4 control the two bonding plates 8 to overlap. If the pressure continues to be high or an unexpected situation occurs, the pressure on the bonding plates 8 can be evenly distributed to avoid one side being directly damaged due to excessive pressure.

[0054] It is worth noting that electronic springs are a common existing technology in the market, and they utilize typical electrostrictive materials such as lead zirconate titanate. These materials exhibit significant electrostrictive properties, producing observable dimensional changes under the influence of an electric field. By applying a voltage to the electrodes through an external power source, an electric field is formed within the material. The magnitude and polarity of the voltage determine the strength and direction of the electric field, thereby controlling the expansion and contraction behavior of the electronic spring. Positive and negative voltages will cause the electronic spring to expand and contract in different directions. For example, within a certain range, a positive voltage may cause the material to elongate, while a negative voltage will cause it to contract.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
