Description

Infection-preventing medical transfer bed

Technical Field

The utility model relates to a transport means technique for loading and uninstalling patient especially relates to a prevent infecting medical transportation bed.

Background

At present, a medical transfer bed is used for moving and transferring patients with inconvenient actions before and after a surgery, the patients are transferred to the transfer bed from a sickbed, and then transferred to an operating table or equipment needing examination/treatment from the transfer bed, or the patients are reversely transferred.

The medical transfer bed sold or used in the market at present mainly comprises two parts, wherein one part is a vehicle body used for moving, and the other part is a moving bed plate mechanism used for transversely moving and receiving patients; for example, the medical patient transport cart disclosed in chinese patent No. 98205338.X includes a cart body and a transport bed top (moving bed plate mechanism) which is composed of transport rollers, driven rollers, and transport cloth belts mounted on the transport rollers and the driven rollers, and the transport bed top can be horizontally translated back and forth under the action of a motor. Also, as disclosed in chinese patent 200610052776.3, "medical patient transfer cart", the moving bed plate mechanism employs a double-layer combination structure of an upper moving bed/upper moving cloth and a lower moving bed/lower moving cloth, and specifically includes a cloth winding shaft frame, a cloth winding shaft, an end joint seat body, a clutch gear, an upper moving bed/upper moving cloth, a lower moving bed/lower moving cloth, and the like.

However, these medical transfer beds have the following disadvantages:

1. problem of hygiene

The transmission strap or the upper and lower moving cloth is directly contacted with the body of a patient, the cloth cover is easy to be dirty and comprises stains such as blood stains, human body exudate, treatment medicine exudate and the like, because the transmission strap or the upper and lower moving cloth is the annular closed transmission cloth, the transmission cloth is hidden in a machine and is difficult to clean and replace, the disassembly and assembly workload of replacing the transmission cloth is not inferior to that of assembling a new machine, and therefore, the problem of the dirty cloth cover cannot be solved. Although the problem of cross infection can be solved by changing the upper and lower moving cloths once every time a patient is transported, the method is not practical, and after the medical equipment is disassembled, the professional is required to debug the equipment again, so that the time is long, and the method is not an optimal solution. In order to avoid cross infection between patients caused by the fact that different patients use the same transfer trolley, the transfer bed capable of automatically laying isolation cushions needs to be designed.

2. Structural problems

The transmission cloth belt (Chinese patent 98205338.X) or the upper moving cloth (Chinese patent 200610052776.3) is driven by the driving rubber roller to rotate, so that the transmission cloth belt or the upper moving cloth sleeved on the rubber roller is driven to transversely move back and forth to be close to or far away from an operating table/sickbed, and as the transmission of the cloth cover needs a certain tension force, the tension degree of the cloth cover needs to be adjusted after long-term use, the cloth cover needs to be replaced when being stretched to a certain degree, otherwise, the guardrails arranged at the two sides of the vehicle body cannot be closed; the cloth cover of the structure is easy to move left and right and needs to be debugged; in addition, the arrangement of the rubber roller can cause many problems, for example, the gap existing between the rubber roller 15 and the end connector seat body 16 in the specification of the medical patient transfer vehicle disclosed in the Chinese patent 200610052776.3, namely the figure 16, is easy to roll clothes into the rubber roller, and the clamp can be used for clamping during the process of transferring patients; and the problems that the rubber roller is aged, the rubber roller needs to be replaced, the running state of the equipment needs to be debugged again and the like exist.

For example, the transmission mechanism of the chinese patent 200610052776.3 adopts a clutch for transmission, and the clutch adopts a mechanical control structure in which two clutch gears are engaged and disengaged, and has the disadvantages of complicated design structure and easy occurrence of failure; particularly, when the clutch part needs to be combined, when the two teeth of the two clutch gears are not coordinated, the combination is not smooth, and when the clutch part needs to be separated, under the condition that the two teeth are meshed, the separation resistance exists, so that the difference of the moving and the positioning is large, and the patient can not be completely transferred.

In addition, the transmission cloth belt or the upper and lower moving cloth is annular closed transmission cloth which is in direct contact with the body of the patient and is a main part for directly receiving and delivering the patient; due to the requirement of medical sanitation, cloth interfaces crack easily caused by the disinfection of cloth surfaces of the transmission cloth belts or the up-and-down moving cloth, and the structural strength is not enough.

3. Safety problem

For example, in the medical patient transfer cart in chinese patent 200610052776.3, the driving mechanism drives the rubber roller to rotate, so that there is a problem that the transmission cloth sleeved on the rubber roller moves back and forth, which may cause a patient to collide with the end connector base 16 due to misoperation, or even fall to the frame of the transfer bed across the end connector base 16. Under the normal state, when a person lies on the transmission cloth, the driving mechanism stops driving the rubber roller to rotate, the transmission cloth is in a static state, and the person only needs to move the up-down moving plate to complete receiving and conveying to a required position. If a patient is on the transfer bed, the patient may hit the end connector base 16 by pressing a button inserted into the bed by mistake, or even fall to the bed frame of the transfer bed across the end connector base 16, resulting in a medical accident.

Compared with the prior art, the beneficial effects of the utility model reside in that:

(1) one of the core points of the utility model is that by arranging the isolation pad laying mechanism, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the upper and lower moving plates, the upper isolation pad fixed on the locking strip is simultaneously rolled between the patient and the upper moving cloth along with the extension of the upper and lower moving plates, thereby isolating the patient from the upper moving cloth; when the moving bed plate mechanism receives a patient and needs to retract the upper and lower moving plates, the locking strip is unlocked and locked, the upper isolation pad moves synchronously along with the upper and lower moving plates and the upper moving cloth and is always arranged between the patient and the upper moving cloth, so that bloodstains or treatment medicines on the patient cannot pollute the upper moving cloth due to the isolation of the upper isolation pad, the upper moving cloth cannot be polluted due to the patient receiving, and the risk of cross infection among the patients is reduced. In addition, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the upper and lower moving plates, the lower isolation pad fixed on the receiving and delivering side of the frame is simultaneously rolled between the lower moving cloth and the operating bed along with the extension of the upper and lower moving plates, and the lower moving cloth cannot be polluted by blood or treatment medicines remained on the operating bed; when the moving bed plate mechanism receives a patient and needs to withdraw the upper and lower moving plates, the lower isolation pad is left on the operating bed, so that blood or treatment medicines remained on the operating bed can not pollute the transfer bed due to the isolation of the lower isolation pad, the sanitary standard of the operating bed during secondary use is ensured, and the risk of cross infection among patients is reduced.

Generally speaking, the utility model discloses prevent infecting medical transportation bed lays the mechanism through setting up the isolation pad, makes it can be in the patient of connecing and send patient in-process, goes up the isolation pad and can guarantee to go up to remove cloth and can not contaminated from beginning to end, and after sending patient back the sick bed simultaneously, go up the isolation pad and stay on the sick bed in step, also can realize the health between patient and the sick bed and keep apart. The lower isolation pad can ensure that the lower movable cloth is not polluted by blood or treatment medicines remained on the operating bed in the process of receiving a patient, and meanwhile, when the patient is received to the transfer bed, the lower isolation pad is synchronously remained on the operating bed to isolate an infection source.

(2) The second core of the utility model is that the locking strip is arranged on the upper moving cloth longitudinally and fixed on the upper moving cloth, and the locking strip is driven by the locking strip driving mechanism to move transversely so as to draw the upper moving cloth to move transversely back and forth on the upper moving plate; when the moving bed plate mechanism receives a patient and needs to retract the upper and lower moving plates and send the patient and needs to extend the upper and lower moving plates (namely when the upper moving plate loads a patient), the upper and lower moving plates move transversely under the driving of the moving bed driving mechanism, the locking strip driving mechanism drives the locking strip and the upper moving plate to move synchronously and transversely, the patient lying on the upper moving plate and the locking strip are relatively static, the friction force generated by the lower moving cloth in relative rotation to the lower moving plate is overcome in the process, the friction force at the contact surface of the upper and lower moving cloth is overcome, the upper moving plate, the upper moving cloth and the patient are relatively static, the lower moving cloth moves relative to the lower moving plate and the upper moving plate, but the contact part of the lower moving cloth and the sickbed surface of the sickbed is still relatively static, the resistance is still small, and the problem. When the moving bed plate mechanism is used for receiving a patient and needs to extend out of the upper and lower moving plates, and sending the patient and needs to retract the upper and lower moving plates, the locking strip driving mechanism self-locks the locking strip to fix the locking strip at an initial position, at the moment, the upper moving plate and the lower moving plate simultaneously move forwards and backwards and transversely (the forward transverse movement means that the upper and lower moving plates are gradually inserted between the patient and a sickbed, and the backward transverse movement means that the upper and lower moving plates are gradually withdrawn between the patient and the sickbed), the lower moving cloth moves relative to the lower moving plate, the contact part of the lower moving cloth and the sickbed/operating bed is kept relatively static with the bed surface, the binding surfaces of the upper moving cloth and the lower moving cloth are also kept relatively static, and the contact part of the upper moving cloth and the patient is also kept relatively static with the patient, therefore, in the moving plate moving up and down, there is no other relative movement, that is, there is no sliding friction between the movable cloth and the bed surface of the sickbed/patient, so the resistance is very small, and the sickbed and the patient are relatively static with the movable cloth contacting with them, and the bed sheet can ensure that the movable plate is smoothly inserted under the patient, and the bed sheet is not driven, the patient is not pushed, and the patient is not pushed or pulled. The whole receiving and delivering process is very smooth, and the friction force and the resistance are small.

Generally speaking, the utility model discloses a power unit that sets up locking strip and locking strip has replaced the mode of transporting cloth through the rotation of drive rubber roll among the prior art, has simplified moving bed plate mechanism's structure, need not the rubber roll just does not have the relevant problem of rubber roll, for example need not to adjust cloth cover tensioning, cloth cover position of walking, press from both sides hair, roll up clothes, the rubber roll ageing need to be changed the rubber roll, the complicated transmission of clutch, the medical accident that takes place to fall and hinder because of the maloperation scheduling problem; meanwhile, the utility model can deliver patients more smoothly, compared with the prior art, the resistance and the friction force in the process of delivering patients are greatly reduced, and the movable plate can be inserted under the patients very smoothly without human intervention; the movable cloth has no friction coefficient requirement, the movable resistance is smaller, the power consumption is smaller, a driving motor with smaller power can be adopted, the transmission is simpler, the load capacity of the whole vehicle is more favorably improved, and the production cost is more favorably reduced.

(3) The upper moving cloth and/or the lower moving cloth are designed into an open form, so that the requirements of disassembly and replacement can be met, the purpose of preventing infection is achieved, and the strength cannot be influenced after disinfection.

The utility model discloses the working process of medical transportation bed of preferred embodiment:

as shown in fig. 26-27, the initial state of the medical transfer bed before the patient is delivered is that the moving bed plate mechanism is stopped on the frame of the vehicle body, and the right side of the medical transfer bed is an operating bed or a hospital bed; the locking strip of the moving bed plate mechanism is locked at the receiving and sending side of the upper moving plate, and the fixing piece is fixed on the frame;

(1) the process that the upper and lower moving plates extend out when a patient is connected is as follows: the locking strip motor of the locking strip driving mechanism is self-locked, the motor does not rotate, the second transmission roller chain is also static, the locking strip is fixed at an initial position and does not move, at the moment, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism to move forwards in a transverse direction, the lower moving cloth moves relative to the lower moving plate, the contact part of the lower moving cloth and the sickbed/operating bed is kept relatively static with the bed surface, the binding surface of the upper moving cloth and the lower moving cloth is also kept relatively static, and the contact part of the upper moving cloth and the patient is also kept relatively static with the patient, so that in the whole moving process of the upper moving plate and the lower moving plate, except the relative movement of the moving cloth and the corresponding moving plate, no other relative movement exists; namely, the sliding friction between the movable cloth and the operating bed or the sickbed surface and between the patient and the upper movable cloth do not exist, so that the resistance is very small, and the contact surface of the bed sheet or the disposable mattress on the bed and the lower movable cloth is relatively static in fact, so that the movable plate can be ensured to be smoothly inserted under the body of the patient, the bed sheet or the disposable mattress can not be driven, and the patient can not be pushed; the patient can be connected to the upper moving bed without human intervention;

in addition, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the up-and-down moving plate, an upper isolation pad fixed on the locking strip is simultaneously involved between the patient and the upper moving cloth along with the extension of the up-and-down moving plate, so that the patient is isolated from the upper moving cloth; the lower isolation pad fixed on the receiving side of the frame is simultaneously rolled between the lower moving cloth and the operating bed along with the extension of the upper moving plate and the lower moving plate, and the lower moving cloth can not be polluted by blood or treatment medicines remained on the operating bed.

(2) The process of retracting the upper and lower moving plates when receiving a patient: after the upper moving plate loads a patient, the locking strip motor rotates, and synchronously drives the second outer side main chain wheels at the two longitudinal sides of the moving bed plate mechanism to rotate through the linkage action of the second connecting rod shaft, at the moment, the locking strips fixed on the second transmission roller chain are pulled to move relatively, and the locking strips are transferred to one side far away from the receiving and delivering side; when the moving bed driving mechanism drives the upper moving plate and the lower moving plate to transversely retract, the locking strips and the upper moving plate synchronously move, and the cloth surface of the upper moving cloth is static relative to the upper moving plate; the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth moves relatively relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth, which is contacted with the sickbed/operating bed, is still relatively static with the sickbed/operating bed;

in addition, when the moving bed plate mechanism receives a patient and needs to retract the upper and lower moving plates, the locking strip is unlocked and locked, the upper isolation pad moves synchronously along with the upper and lower moving plates and the upper moving cloth and is always arranged between the patient and the upper moving cloth, so that bloodstains or treatment medicines on the patient cannot pollute the upper moving cloth due to the isolation of the upper isolation pad, the upper moving cloth cannot be polluted due to the patient receiving, and the risk of cross infection among the patients is reduced; the lower isolation pad is left on the operating bed, so that blood or treatment medicines remained on the operating bed can not pollute the transfer bed due to the isolation of the lower isolation pad, the sanitary standard of the operating bed during secondary use is ensured, and the risk of cross infection among patients is reduced.

(3) The process of extending the upper and lower movable plates when a patient is sent out is as follows: the patient is transferred to the medical transfer bed, namely the upper moving plate still loads the patient, and the moving bed driving mechanism drives the upper and lower moving plates to move forwards and transversely extend; the locking strip and the upper moving plate move synchronously because the locking strip motor still rotates; at the moment, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth relatively moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth, which is in contact with the sickbed/operating bed, is still relatively static with the sickbed/operating bed;

in addition, when the moving bed plate mechanism of the transfer bed sends a patient to extend out of the up-and-down moving plate, the patient and the upper isolation pad synchronously and transversely move along with the extension of the up-and-down moving plate.

(4) When a patient is sent, the process of retracting the upper and lower moving plates is as follows: when a patient is sent to the upper part of a sickbed/an operation bed, the locking strip motor of the locking strip driving mechanism is self-locked, the motor does not rotate, the second transmission roller chain is also still, the locking strip is fixed at the initial position and does not move, at the moment, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism to move backwards and transversely, the lower moving cloth moves relative to the lower moving plate, the contact part of the lower moving cloth and the sickbed/operation bed is kept relatively still with the bed surface, the joint surface of the upper moving cloth and the lower moving cloth is also kept relatively still, and the contact part of the upper moving cloth and the patient is also kept relatively still with the patient, so that in the whole moving process of the upper moving plate and the lower moving plate, the moving cloth and the corresponding moving plate do not move relatively, and the transfer is completed.

In addition, after the patient is sent to the sick bed top, loosen the upper isolation pad of fixing on the locking strip, when the moving bed board mechanism of transport bed withdraws from top to bottom the movable plate after sending the people, the upper isolation pad is stayed between patient and the sick bed, has guaranteed the isolated state between patient and the sick bed, reduces infected risk.

After above-mentioned step (1) - (4), the transport bed has accomplished the action of once transporting and the action of laying of an isolation pad simultaneously, and the isolation pad between the upper and lower removal board has been used, at this moment, can utilize rolling motor to drive narrow strip edgewise 613, makes a set of isolation pad take one's place down, also can not utilize rolling motor to drive taking one's place of a set of isolation pad down certainly, and above-mentioned two kinds of running state can not influence the normal transport function of transport bed, explain the utility model discloses the isolation pad function of laying of addding, the structure is ingenious, can not produce any influence to the normal transportation of transport bed.

Example 2

Compared with the example 1, the infection-preventing medical transfer bed in the example 2 is different from the single-layer structure of the isolation pad, namely, one side of the single-layer isolation pad is fixed on the receiving and sending side of the locking strip or the frame, and the rest structure is the same as the example 1. The embodiment illustrates that when the isolation pad is a bed sheet, the bed sheet required in different places can be replaced according to actual use requirements. Of course, the isolation pad of this embodiment 2 can be laid by the automatic unwinding device.

As shown in fig. 26 to 27, an infection-preventing medical transfer bed comprises a vehicle body with a lifting mechanism and universal casters, a moving bed plate mechanism for laterally moving a patient; the moving bed plate mechanism is arranged on a frame of the vehicle body; the moving bed plate mechanism comprises an upper moving plate 1, upper moving cloth 2, a lower moving plate 3 and lower moving cloth 4; the lower moving plate is arranged below the upper moving plate, and the upper moving plate and the lower moving plate synchronously move forwards or backwards and transversely; the upper moving cloth is coated on the periphery of the upper moving plate, a locking strip 5 is longitudinally fixed on the upper moving cloth, and the locking strip is locked on the delivery side of the upper moving cloth or moves along with the upper moving cloth after being unlocked; the lower moving cloth is coated on the periphery of the lower moving plate, and two ends of the lower moving cloth are fixed on a frame of the vehicle body and positioned on the receiving and delivering side of the lower moving plate; this prevent infection medical transportation bed still includes the isolation pad mechanism of laying, isolation pad mechanism of laying includes the isolation pad (this isolation pad can be for last isolation pad 611 or lower isolation pad 612), the isolation pad is laid and is moved between the cloth at last and move down, the side of delivering is fixed in connecing of locking strip or frame to isolation pad one side.

Example 3

Compared with the embodiment 1, the medical transfer bed of the embodiment 3 is different from the locking strip driving mechanism, and the rest of the structure is the same as the embodiment 1. In this embodiment, the locking bar driving mechanism is one of the existing locking mechanisms, such as a ratchet, a structure similar to the ratchet principle, a brake mechanism, or an electromagnetic device. When the locking mechanism such as a ratchet wheel or an electromagnetic device is released to unlock the lock (namely, the upper moving plate loads a patient), the friction force between the upper moving cloth and the upper moving plate is large enough to overcome the friction generated by the passive movement of the lower moving cloth, so that the upper moving cloth, the patient and the upper moving plate are relatively static because the patient presses on the upper moving cloth.

(1) the process that the upper and lower moving plates extend out when a patient is connected is as follows: the locking strip driving mechanism (such as a ratchet wheel or an electromagnetic device) is self-locked with the locking strip, the locking strip is fixed at an initial position and does not move, at the moment, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism to move forwards in a transverse direction, the lower moving cloth moves relative to the lower moving plate, the contact part of the lower moving cloth and the sickbed/operating bed and the bed surface are kept relatively static, the binding surfaces of the upper moving cloth and the lower moving cloth are also kept relatively static, and the contact part of the upper moving cloth and the patient are also kept relatively static, so that in the integral moving process of the upper moving plate and the lower moving plate, the moving cloth and the corresponding moving plate do not move relatively and do not move relatively; namely, the sliding friction between the movable cloth and the operating bed or the sickbed surface and between the patient and the upper movable cloth do not exist, so that the resistance is very small, and the contact surface of the bed sheet or the disposable mattress on the bed and the lower movable cloth is relatively static in fact, so that the movable plate can be ensured to be smoothly inserted under the body of the patient, the bed sheet or the disposable mattress can not be driven, and the patient can not be pushed; the patient can be connected to the upper moving bed without human intervention;

in addition, when a moving bed plate mechanism of the transfer bed receives a patient and extends out of the up-down moving plate, the up-down moving plate pushes off a connecting point on the easy-tearing position of the isolation pad, so that the isolation pad is disconnected with the edge of the narrow strip; the upper isolation pad fixed on the locking strip is simultaneously involved between the patient and the upper moving cloth along with the extension of the up-down moving plate, so that the patient is isolated from the upper moving cloth; the lower isolation pad fixed on the receiving side of the frame is simultaneously rolled between the lower moving cloth and the operating bed along with the extension of the upper moving plate and the lower moving plate, and the lower moving cloth can not be polluted by blood or treatment medicines remained on the operating bed.

(2) The process of retracting the upper and lower moving plates when receiving a patient: after the upper moving plate loads a patient, the ratchet wheel is unlocked, and the moving bed driving mechanism drives the upper moving plate and the lower moving plate to transversely retract; generally, as the patient presses on the upper moving cloth, the friction force between the upper moving cloth and the upper moving plate is large enough to overcome the friction generated by the passive movement of the lower moving cloth, so that the upper moving cloth and the patient are relatively static, and the locking strip is transferred to the side far away from the receiving and delivering side; at the moment, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth relatively moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth, which is in contact with the sickbed/operating bed, is still relatively static with the sickbed/operating bed;

(3) The process of extending the upper and lower movable plates when a patient is sent out is as follows: the patient is transferred to the medical transfer bed, namely the upper moving plate still loads the patient, the ratchet wheel still loosens and locks, and the moving bed driving mechanism drives the upper and lower moving plates to transversely extend forwards; the patient still presses the upper moving cloth, and the friction force between the upper moving cloth and the upper moving plate is large enough to overcome the friction generated by the passive movement of the lower moving cloth, so that the upper moving cloth and the patient are relatively static; at the moment, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth relatively moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth, which is in contact with the sickbed/operating bed, is still relatively static with the sickbed/operating bed;

In the steps (2) - (3), for the patient with thinness and light weight, even if the patient presses the upper moving cloth, the friction force generated by the patient is small and is not enough to overcome the friction generated by the passive movement of the lower moving cloth, so that the patient can be driven by the lower moving cloth to move, therefore, in order to avoid the situation, in the steps (2) - (3), the clutch is additionally arranged, the synchronous movement of the moving plate and the locking strip is realized, and the upper moving cloth is ensured not to move; and the power consumption thereof is reduced as compared with the two drive mechanisms of embodiment 1.

(4) When a patient is sent, the process of retracting the upper and lower moving plates is as follows: when a patient is sent to the upper part of a sickbed/an operating bed, the ratchet wheel locks the locking strip, at the moment, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism to move backwards in a transverse direction, the upper moving cloth and the patient contact part and the patient also keep relatively static, the lower moving cloth moves relative to the lower moving plate, the lower moving cloth and the sickbed/operating bed contact part and the bed surface also keep relatively static, the binding surfaces of the upper moving cloth and the lower moving cloth also keep relatively static, and the upper moving cloth and the patient contact part and the patient also keep relatively static.

Therefore, this embodiment 4 provides a medical transportation bed of easy change removal cloth, and this medical transportation bed difference lies in will moving cloth and/or move cloth design into the open-ended form down, can satisfy the demand of dismantling the change, reaches the infection-preventing purpose. The rest of the structure is the same as in example 1.

Specifically, compared with example 1, the medical transfer bed of example 4 is different in that a longitudinal opening is arranged on the upper moving part; two sides of the longitudinal opening of the upper moving cloth are respectively connected with a rigid limiting strip 12; a limiting groove is arranged between the upper clamping strip and the lower clamping strip; the rigid limiting strip is arranged in the limiting groove.

Preferably, as shown in fig. 24-25, the fixing member 13 of the present embodiment includes two sets, each set of the fixing member includes a fixing seat 131 and a rigid fastening strip 132; each fixing seat is provided with a through groove 1311 for the downward moving cloth to pass through, and the width of the rigid fastening strip is larger than that of the through groove. In addition, two strip-shaped notches 221 are formed in the frame of the vehicle body, after the lower moving cloth covers the periphery of the lower moving plate, cloth openings at two ends of the lower moving cloth sequentially penetrate through the strip-shaped notches of the frame and the through grooves of the fixing seat respectively, and then the lower moving cloth is fixed with the rigid fastening strips respectively and limited outside the through grooves of the fixing seat. Preferably, the rigid fastening strip is provided with a groove 1221, and the cloth opening of the lower moving cloth is inserted into the groove and then fixed to the rigid fastening strip by a rivet. As a further preferred scheme, each set of the fixing members may be provided in a sectional manner, as shown in fig. 25, which is divided into three sections in this embodiment, and may be divided into two sections. The segmented mount has the benefit of increasing the rigidity of the vehicle frame.
