Description

TECHNICAL FIELD

[0001] The utility model relates to a lifter especially relates to a glass lifter assembly of vehicle door with observation port. BACKGROUND

[0002] In truck door design, glass lifter is an important functional component, especially on truck doors with observation ports, its application scenario and use process are more special. Under normal circumstances, the glass lifter on the truck door is used to control the lifting of the window glass to realize ventilation, lighting or sealing functions. However, in the structure of the door with observation port, the design of the glass lifter is challenged due to the existence of the observation port. The traditional glass lifter needs to bypass the observation port area during operation, which leads to the complication of its movement trajectory and may affect the stability and reliability of the operation, increasing the risk of mechanical component wear.

[0003] Chinese patent document CN111890891A is a heavy truck door assembly with an observation window for the co-driver, which includes a door body made of a door inner plate assembly and a door outer plate edge covering, with a large-size observation window in the lower part and an observation window glass bonded on the observation window. The upper window is welded with a partition guide rail assembly at the front and rear 3 / 4, constituting the static and dynamic two areas of the front and rear windows, wherein the front area is provided with a fixed glass assembled on the door body by bolts, and the rear area is provided with a lifting glass assembled on the electric glass lifter by bolts, and the electric glass lifter is assembled on the door body by bolts. The door body is provided with a door trim panel and a door sealing system.

[0004] The prior art proposes a single-track glass lifter design scheme, aiming to partially solve the interference problem between the observation port and the glass lifter. This design avoids blocking the observation port by limiting the lifting range of the glass, but its defects are also obvious. First of all, the single-track design can only realize the lifting of partial glass, which cannot meet the user's demand for full-window lifting. Secondly, due to its structural limitations, it cannot adapt to double-rail glass lifters, thus failing to provide a more efficient and stable lifting experience. In addition, in actual application, the single-track design may cause uneven stress during glass lifting, further reducing the durability and safety of the system. These problems show that there is still much room for improvement in the prior art. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model provides a glass lifter assembly for a vehicle door with an observation port, which can be arranged around the observation port and has a double-rail.

[0006] In order to achieve the above object, the technical scheme of the utility model is as follows: a glass lifter assembly of a vehicle door with an observation port, comprising a vehicle door provided with an observation port, a lifter provided on the vehicle door, the lifter comprising slide rails fixedly arranged on the left and right sides of the observation port and arranged in parallel, a steel rope sequentially penetrating from both ends of the two slide rails and a rotating motor for driving the steel rope, a clamping plate for clamping glass is arranged on each slide rail and the clamping plate moves up and down along the slide rail under the driving of the steel rope controlled by the rotating motor, the steel rope is arranged around the observation port, two rope tensioning points are arranged on the upper side of the observation port and no rope tensioning point is arranged on the lower side of the observation port.

[0007] The utility model has the advantages that: the steel rope is arranged around the observation port and two rope tensioning points are arranged on the upper side of the observation port, so that the steel rope can be effectively prevented from falling into the observation port area due to gravity, thereby ensuring the stability and safety of the glass lifting process.

[0008] Further, one of the rope tensioning points is arranged between the two slide rails and is located at a position deviated to one side of the center line of the two slide rails, and the other rope tensioning point is arranged on the other slide rail.

[0009] By reasonably distributing the positions of the two rope tensioning points, the stress of the steel rope during operation is more uniform, and the problems of deformation or fracture caused by local stress concentration are avoided.

[0010] Further, the driving motor is fixed on the vehicle door, the driving motor comprises a wire wheel for fixing and driving the steel rope, and the rope tensioning point between the two slide rails is the wire wheel of the driving motor.

[0011] The wire wheel driving the motor is used as the rope tensioning point between the sliding rails, which not only integrates the functional components, but also reduces the use of independent tensioning devices, making the overall structure more compact and simple. This design makes full use of the functions of existing components, avoids the addition of complex parts, and reduces production and assembly costs. At the same time, since the wire wheel itself has high strength and wear resistance, it can better withstand the tension of the steel rope, further improving the durability and reliability of the system. As a preferred mode, the wire wheel surface can be provided with a non-slip coating or groove design to enhance the friction with the steel rope and prevent slipping; in addition, the driving motor can be fixed to the inner wall of the door through a damping pad to reduce vibration and noise during operation.

[0012] Further, the rope tensioning points arranged on the sliding rails are buckles, and the steel ropes respectively passing out of the two sliding rails are clamped in the buckles.

[0013] By fixing the steel rope at the tensioning point on the sliding rail in the form of a buckle, not only is the operation simple, but also the installation and disassembly of the steel rope can be quickly completed, greatly facilitating the later maintenance work. In addition, the buckle design can effectively constrain the position of the steel rope, avoid its deviation or derailment during operation, and thus ensure the smoothness and consistency of the glass lifting action. As a preferred mode, the inside of the buckle can be designed as an arc contact surface to match the shape of the steel rope to reduce wear and tear and disperse pressure; at the same time, locking screws can be provided outside the buckle to further reinforce the steel rope and prevent loosening.

[0014] Further, the steel rope is provided with two transmission sleeves clamped in the buckle, and the steel ropes respectively passing out of the two sliding rails and clamped in the buckle are each sleeved with a transmission sleeve, the outer diameter surface of the transmission sleeve and the buckle form an interference fit, and the inner diameter surface of the transmission sleeve and the steel rope form a clearance fit.

[0015] By providing a transmission sleeve on the steel rope and forming an interference fit between the transmission sleeve and the buckle and a clearance fit between the transmission sleeve and the steel rope, the transmission efficiency can be significantly improved while ensuring normal operation of the steel rope, preventing the buckle from being directly clamped to the steel rope to cause failure. This design not only protects the steel rope from excessive extrusion damage, but also ensures that the buckle firmly clamps the steel rope to maintain a stable tensioning state. As a preferred mode, the transmission sleeve can be made of a high-molecular polymer material, such as polyurethane or nylon, to balance flexibility and wear resistance; at the same time, the length of the transmission sleeve can be customized according to the diameter of the steel rope and the size of the buckle to achieve the best fit effect and further optimize the transmission performance.

[0019] The glass lifter assembly with an observation port of the embodiment of the utility model as shown in the figure comprises a door 1, a lifter and a driving motor 51. Figs. 1-3 The door 1 is provided with an observation port 11, and two parallel slide rails 2 are fixedly installed on the left and right sides of the observation port 11, which are used for supporting the up and down movement of the glass. The two ends of the slide rail 2 are penetrated by a steel wire 3, and the steel wire 3 is driven by the driving motor 51, so as to realize the lifting function of the glass. A clamping plate 4 is further arranged on the slide rail 2, which can clamp the glass and move up and down along the slide rail 2 under the driving of the steel wire 3, so as to complete the lifting action of the glass.

[0020] The steel wire 3 is arranged around the four peripheral edges of the observation port 11, and two rope tensioning points 5 are arranged above the steel wire 3, and no rope tensioning point 5 is arranged below the steel wire 3. Such design can effectively prevent the steel wire 3 from falling into the area of the observation port 11 due to gravity, and simplify the structure design. One of the two rope tensioning points 5 is located between the two slide rails 2 and is more inclined to one of the slide rails 2; the other rope tensioning point 5 is directly arranged on the other slide rail 2. Such distribution mode not only ensures that the steel wire 3 will not fall, but also maintains the simplicity of the overall structure.

[0021] The driving motor 51 is fixed on the door 1 and comprises a rotatable wire wheel 511 for fixing and driving the steel wire 3. The rope tensioning point 5 located between the two slide rails 2 is actually the wire wheel 511 of the driving motor 51, which not only saves space but also improves the transmission efficiency. In addition, the other rope tensioning point 5 arranged on the slide rail 2 is a buckle 52, which is used to firmly fix the steel wire 3 penetrating out of the two slide rails 2. In order to further optimize the structure, two steel wires 3 are clamped in the buckle 52, and a transmission sleeve 31 is further sleeved on each steel wire 3. The outer diameter surface of the transmission sleeve 31 is in interference fit with the buckle 52, and the inner diameter surface is in clearance fit with the steel wire 3. Such design can not only improve the transmission efficiency of the steel wire 3, but also avoid the buckling phenomenon of the buckle 52 to the steel wire 3.

[0022] The working principle of the technical scheme is as follows: when the driving motor 51 starts, the wire wheel 511 starts to rotate and pulls the steel wire 3 to move. Since the two ends of the steel wire 3 are respectively inserted into the slide rail 2, the movement of the steel wire 3 can drive the clamping plate 4 to move up and down along the slide rail 2. The clamping plate 4 clamps the glass, thereby realizing the lifting function of the glass. The two rope tensioning points 5 provided above the observation port 11 ensure that the steel wire 3 always remains in a tensioned state, preventing it from falling into the observation port 11 area due to gravity. The transmission sleeve 31 in the buckle 52 is designed by interference fit and clearance fit, which further improves the transmission efficiency of the steel wire 3, and also avoids the problem of jamming caused by excessive friction.

[0023] The above embodiment is only one of the preferred specific embodiments of the present application, and the usual changes and replacements made by those skilled in the art within the scope of the technical scheme of the present application are all included in the protection scope of the present application.
