Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile wiper fixing structure, in particular to an automobile wiper fixing assembly structure. BACKGROUND

[0002] The working principle of the automobile wiper is that the motor drives the transmission mechanism to convert the rotary motion of the motor into the reciprocating swing of the wiper arm, thereby driving the wiper blade to perform the water scraping action on the windshield. The automobile wiper and the wiper motor are usually connected by a connecting rod mechanism. The automobile wiper and the wiper motor are usually connected to the automobile frame by the mounting bracket.

[0003] The mounting bracket in the prior art is mostly in bulk, that is, the wiper is connected to the automobile frame by the wiper bracket, and the wiper motor is connected to the automobile frame by the motor bracket. When the motor vibrates, it can cause the motor bracket and the automobile frame to loosen. Once the connection is loose, it not only greatly reduces the stability of the wiper motor, but also may cause abnormal shaking of the wiper during operation, poor water scraping effect and other problems. SUMMARY

[0004] In order to improve the stability of the installation between the wiper motor and the wiper, the application provides an automobile wiper fixing assembly structure.

[0005] The automobile wiper fixing assembly structure provided by the application adopts the following technical scheme:

[0006] An automobile wiper fixing assembly structure, comprising a fixed tube, a fixed plate and two shaft sleeves, the fixed tube is a hollow tube, a plurality of reinforcing ribs are distributed along the axial direction of the fixed tube, the fixed plate is arranged on the fixed tube, a first mounting hole is formed in the fixed plate, two shaft sleeves are arranged at both ends of the fixed tube in the length direction, and each shaft sleeve is provided with a mounting block having a second mounting hole.

[0007] By adopting the above technical scheme, the fixed tube is designed as a hollow tube with reinforcing ribs, which not only ensures its strength and rigidity and can withstand various stresses during wiper operation, but also reduces the weight. On this basis, the fixed plate is connected to the fixed tube, and the shaft sleeves are arranged at both ends of the fixed tube. This connection mode makes the entire assembly form a stable overall structure, and each component cooperates with each other to resist the external force generated by the wiper motor and the wiper during operation, thereby reducing the possibility of wiper failure caused by loosening or deformation of the components.

[0008] Preferably, the reinforcing ribs are arranged in a cross-sectional shape, and the four ends of the reinforcing ribs are fixedly connected to the inner wall of the fixed tube.

[0009] By adopting the technical scheme, the cross-shaped reinforcing rib can form a stable support frame inside the fixed tube. When the wiper blade is subjected to external force, the structure can uniformly disperse the force in all directions of the fixed tube, reducing the possibility of deformation or rupture of the fixed tube due to excessive local stress, thereby improving the structural strength and stability of the fixed tube; the layout of the cross-shaped reinforcing rib enables the fixed tube to better resist twisting deformation when subjected to torsional force.

[0010] Preferably, one end of the shaft sleeve is provided with a mounting column that can be inserted and matched with the end of the fixed tube, and the side surface of the mounting column is uniformly distributed with a plurality of limiting grooves in the circumferential direction. When the mounting column is inserted and matched with the fixed tube, the end of the fixed rod is deformed to form a limiting protrusion matched with the limiting grooves.

[0011] By adopting the technical scheme, the insertion and matching of the mounting column and the end of the fixed tube can achieve accurate positioning between the shaft sleeve and the fixed tube, ensuring that the installation position of the shaft sleeve on the fixed tube is accurate. The limiting grooves uniformly distributed on the side surface of the mounting column are matched with the limiting protrusion deformed at the end of the fixed tube, so that a reliable mechanical connection is formed between the shaft sleeve and the fixed tube. This connection method can effectively prevent the shaft sleeve from moving axially and circumferentially on the fixed tube, ensuring the stability of the wiper blade fixing assembly structure. Even under the working condition of long-time high-frequency vibration of the wiper blade, the shaft sleeve is not easy to loosen.

[0012] Preferably, a plurality of positioning grooves are arranged on the hollow tube, and an arc-shaped plate that can be fitted with the outer peripheral surface of the fixed tube is arranged on the fixed plate, and a plurality of clamping blocks that can be matched with the positioning grooves are arranged on the arc-shaped plate. When the fixed plate is installed on the hollow tube, the clamping blocks are respectively clamped and matched with the positioning grooves.

[0013] By adopting the technical scheme, the cooperation of the positioning grooves and the clamping blocks can ensure that the fixed plate is accurately installed at the predetermined position of the hollow tube; and through the clamping cooperation between the clamping blocks and the positioning grooves, the possibility of displacement or rotation of the fixed plate on the hollow tube can be reduced, thereby enhancing the structural stability of the wiper blade fixing assembly.

[0014] Preferably, a damping gasket is arranged on the arc-shaped plate, and the damping gasket abuts against the outer surface of the hollow tube when the fixed plate is installed on the hollow tube.

[0015] By adopting the technical scheme, the damping gasket can effectively absorb and buffer vibration, reducing the transmission of vibration between the fixed plate and the hollow tube; and the damping gasket can fill the possible small gap between the arc-shaped plate and the hollow tube, making the connection between the fixed plate and the hollow tube more compact and flat, thereby improving the stability of the entire wiper blade fixing assembly.

[0016] Preferably, a flange structure is arranged at the edge of the fixed plate.

[0017] By adopting the technical scheme, the flanging structure can increase the thickness and rigidity of the edge of the fixing plate, and increase the bearing capacity of the fixing plate.

[0018] Preferably, a plurality of reinforcing plates are fixedly connected to the mounting block and the shaft sleeve, and the plurality of reinforcing plates are uniformly distributed around the circumference of the reinforcing plate.

[0019] By adopting the technical scheme, the mounting block and the shaft sleeve are key components in the wiper fixing assembly, and the reinforcing plate can effectively increase the stability of the connection between the mounting block and the shaft sleeve. The reinforcing plate can disperse the force, reduce the possibility of relative deformation and displacement between the mounting block and the shaft sleeve, and reduce the possibility of loosening and cracking at the connection part, thereby improving the strength and reliability of the entire structure.

[0020] The technical effects of the utility model mainly lie in the following aspects:

DETAILED DESCRIPTION

[0030] The following will be described in detail in combination with the accompanying Figures 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0031] The present application discloses a fixed assembly structure of a car wiper.

[0032] With reference to Figure 1 and Figure 2 , the fixed assembly structure of the car wiper of the present embodiment comprises a fixed pipe 1, a fixed plate 2 and two shaft sleeves 3. The fixed pipe 1 is a hollow pipe, and a plurality of reinforcing ribs 4 are distributed along the axial direction of the fixed pipe 1. The reinforcing ribs 4 are arranged in a cross-section, and the four ends of the reinforcing ribs 4 are fixedly connected to the inner wall of the fixed pipe 1.

[0033] With reference to Figure 1 and Figure 2 , the fixed plate 2 is fixedly connected to the fixed pipe 1 by pressure riveting, and the edge of the fixed plate 2 is provided with a flanging structure. A plurality of first mounting holes 5 for mounting a motor are formed in the fixed plate 2, and a third mounting hole 7 for mounting the fixed plate 2 on a vehicle frame is formed in the fixed plate 2. The two shaft sleeves 3 are arranged at the two ends of the fixed pipe 1 in the length direction, and the two shaft sleeves 3 are respectively provided with mounting blocks 8 for mounting the shaft sleeves 3 on second mounting holes 6 of the vehicle frame. The third mounting hole 7 and the two second mounting holes 6 form a three-point support to increase the stability of the whole on the vehicle frame.

[0034] With reference to Figure 1 and Figure 2The fixed tube 1 is designed as a hollow tube with reinforcing ribs 4, which not only ensures its strength and rigidity and can withstand various stresses during the operation of the wiper, but also reduces the weight. On this basis, the fixed plate 2 is connected to the fixed tube 1, and the shaft sleeve 3 is arranged at both ends of the fixed tube 1. This connection mode makes the entire combined component form a stable overall structure, and each part cooperates with each other to resist external forces generated during the operation of the wiper motor and the wiper, thereby reducing the possibility of wiper failure caused by loose or deformed parts.

[0035] With reference to Figure 2 and Figure 4 , the cross-shaped reinforcing ribs 4 can form a stable support frame inside the fixed tube 1. When the wiper is subjected to external forces, this structure can evenly distribute the force in all directions of the fixed tube 1, reducing the possibility of deformation or rupture of the fixed tube 1 due to excessive local stress, thereby improving the structural strength and stability of the fixed tube 1. The layout of the cross-shaped reinforcing ribs 4 enables the fixed tube 1 to better resist twisting deformation when subjected to torsional forces.

[0036] With reference to Figure 1 and Figure 2 , the flanging structure on the fixed plate 2 can increase the thickness and rigidity of the edge of the fixed plate 2, and increase its ability to withstand external forces. The flanging structure can reduce the possibility of deformation, cracking or damage of the edge of the fixed plate 2, thereby improving the structural strength and stability of the entire fixed plate 2.

[0037] With reference to Figure 3 and Figure 5 , one end of the shaft sleeve 3 is provided with a mounting column 16 which can be inserted and matched with the end of the fixed tube 1. The side surface of the mounting column 16 is uniformly distributed with a plurality of limiting grooves 9 along the circumference thereof. When the mounting column 16 is inserted and matched with the fixed tube 1, a limiting protrusion 10 is formed on the end of the fixed tube 1 by deforming the end of the fixed tube 1. The insertion and matching of the mounting column 16 with the end of the fixed tube 1 can realize the precise positioning between the shaft sleeve 3 and the fixed tube 1, ensuring that the installation position of the shaft sleeve 3 on the fixed tube 1 is accurate. The limiting grooves 9 uniformly distributed along the circumference of the side surface of the mounting column 16 are matched with the limiting protrusion 10 formed by deforming the end of the fixed tube 1, so that a reliable mechanical connection is formed between the shaft sleeve 3 and the fixed tube 1. This connection mode can effectively prevent the shaft sleeve 3 from moving axially and circumferentially on the fixed tube 1, ensuring the stability of the structure of the wiper fixing combined component. Even under the working condition of long-time high-frequency vibration of the wiper, the shaft sleeve 3 is not easy to loosen.

[0038] With reference to Figure 2 and Figure 4The hollow pipe is provided with a plurality of positioning grooves 11, and the fixing plate 2 is fixedly connected with an arc-shaped plate 12 which can be attached to the outer circumferential surface of the fixing pipe 1, and the arc-shaped plate 12 is fixedly connected with a plurality of clamping blocks 13 which can be matched with the plurality of positioning grooves 11, and when the fixing plate 2 is installed on the hollow pipe, the plurality of clamping blocks 13 are respectively clamped and matched with the positioning grooves 11. The matching of the positioning grooves 11 and the clamping blocks 13 can ensure that the fixing plate 2 is accurately installed on the predetermined position of the hollow pipe, and through the clamping and matching between the clamping blocks 13 and the positioning grooves 11, the possibility of displacement or rotation of the fixing plate 2 on the hollow pipe can be reduced, and the structural stability of the wiper fixing assembly is enhanced.

[0039] With reference to Figure 2 and Figure 4 , the arc-shaped plate 12 is fixedly connected with a damping pad 14 on the side surface close to the fixing pipe 1, and when the fixing plate 2 is installed on the hollow pipe, the damping pad 14 is in abutment with the outer surface of the hollow pipe. The damping pad 14 can effectively absorb and buffer vibration, reduce the transmission of vibration between the fixing plate 2 and the hollow pipe, and the damping pad 14 can fill the possible small gap between the arc-shaped plate 12 and the hollow pipe, so that the connection between the fixing plate 2 and the hollow pipe is more compact and flat, thereby improving the stability of the entire wiper fixing assembly.

[0040] With reference to Figure 1 and Figure 5 , a plurality of reinforcing plates 15 are further included, and the plurality of reinforcing plates 15 are fixedly connected on the mounting block 8 and the shaft sleeve 3, and the plurality of reinforcing plates 15 are uniformly distributed around the circumferential direction of the reinforcing plate 15. The mounting block 8 and the shaft sleeve 3 are key components in the wiper fixing assembly, and the arrangement of the reinforcing plate 15 can effectively increase the stability of the connection between the two. The reinforcing plate 15 can disperse the acting force, reduce the possibility of relative deformation and displacement between the mounting block 8 and the shaft sleeve 3, and reduce the possibility of loosening and cracking at the connection part, thereby improving the strength and reliability of the entire structure.

[0041] Of course, the above is only a typical example of the present application, and in addition to this, the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
