Description

Technical Field

[0001] The utility model relates to the technical field of automobile ball heads, in particular to a windshield wiper ball head for a pure electric commercial vehicle. Background Art

[0002] The connecting rod assembly includes a driver side connecting rod and a passenger side connecting rod. The crank is connected through a double ball head and drives the driver side connecting rod and the passenger side connecting rod. The connecting rod assembly also includes a driver side rocker arm and a passenger side rocker arm, as well as a driver side support shaft and a passenger side support shaft. The above two support shafts respectively support the wiper arm assemblies located on the driver side and the passenger side.

[0003] After searching, the application with patent publication number CN207157170U discloses a ball head for a car wiper system. The ball head body includes a first ball head portion, a second ball head portion and a joint portion. The interior of the first ball head portion is hollow, and a transmission column is axially extended at the center of the upper end of the second ball head portion. The first ball head portion is sleeved on the outside of the transmission column, and the first ball head portion is anti-rotatably engaged with the transmission column. A threaded column is axially extended at the upper end of the transmission column, and the upper end of the threaded column passes through the first ball head portion and is connected to an adjusting nut. The ball head is installed on the connecting rod through the threaded column and the nut, thereby improving the convenience of installation.

[0004] However, due to the setting of the threaded column and the nut, when the ball head and the ball head buckle are rotated, the threaded column is likely to rotate on the nut, causing the threaded column and the nut to loosen and shake, and the connection is not firm. At the same time, since the two sets of connecting rods are connected by the ball head and the ball head buckle, the stability of the connection between the ball head buckle and the connecting rod is low, causing the ball head buckle to easily fall off the connecting rod.

[0005] Therefore, we proposed a wiper ball head for pure electric commercial vehicles. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a wiper ball head for a pure electric commercial vehicle, which solves the problems of the loose connection of the ball head of the prior device and the low stability of the snap connection of the ball head.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a wiper ball head for a pure electric commercial vehicle, comprising a connecting rod A and a connecting rod B;

[0008] The left side of the connecting rod A is equipped with a ball head, and the right side of the ball head is fixedly installed with a bolt. The left side of the connecting rod A is provided with a through hole that matches the specification of the bolt, and the inner wall of the through hole is fixedly installed with a thread A that matches the specification. After the bolt passes through the through hole, it protrudes from the connecting rod A. The right side of the connecting rod A is equipped with a sealing cover that matches the specification of the bolt, and the inner wall of the sealing cover is equipped with a thread B that matches the specification, and the thread B rotates in opposite directions to the thread A.

[0009] A through mounting hole is provided on the right side of the connecting rod B, and four groups of mounting grooves with relative positions are provided on the inner wall of the mounting hole. A ball head buckle with matching specifications is assembled in the mounting hole, and a limiting sleeve located on the right side of the connecting rod B is fixedly installed on the outer wall of the right side of the ball head buckle, and four groups of limiting grooves with relative positions and matching specifications are provided on the outer wall of the limiting sleeve, and four groups of limiting blocks with relative positions and matching specifications as well as the mounting grooves are fixedly installed on the outer wall of the ball head buckle, and a ball head groove matching the specifications of the ball head is provided on the right side of the ball head buckle.

[0010] Preferably, a groove is provided on the left side of the ball head, which can reduce the friction between the left side of the ball head and the ball head buckle, thereby improving the stability and smoothness of the rotation between the ball head and the ball head buckle.

[0011] Preferably, the contact surface between the bolt and the left side of the connecting rod A is equipped with a sealing gasket A of matching specifications, and the sealing gasket A is made of rubber material, which can improve the stability and sealing of the connection between the left side of the connecting rod A and the bolt and prevent dust from entering the through hole.

[0012] Preferably, the contact surface between the sealing cover and the right side of the connecting rod A is equipped with a sealing gasket B of matching specifications, and the sealing gasket B is made of rubber material, which can improve the stability and sealing of the connection between the right side of the connecting rod A and the sealing cover.

[0013] Preferably, a relatively positioned slot is provided on the right side of the limit block, which can improve the stability and firmness of the connection between the ball head buckle and the connecting rod B.

[0014] Preferably, a gap is left between the limit block, the limit sleeve and the ball head buckle, and iron powder glue is installed in the gap, so that the ball head buckle and the connecting rod B can be connected into a whole, preventing the ball head buckle from expanding and cracking, which would cause the ball head and the ball head buckle to loosen.

[0015] 1. The wiper ball head for pure electric commercial vehicles is installed on the connecting rod A through the arrangement of bolts, threads A and sealing covers. The ball head is installed on the connecting rod A through the bolts and threads A, and then the sealing cover is installed on the right end of the bolt. The threads A and B rotate in opposite directions. When the bolts and threads A rotate, the threads B in opposite directions can limit the bolts, thereby ensuring the firmness of the connection between the ball head and the connecting rod A.

[0016] 2. At the same time, by setting the ball head buckle, limit sleeve and limit block, the ball head buckle is installed on the connecting rod B. The limit sleeve can limit the top surface of the connecting rod B, and the limit block can limit the bottom surface of the connecting rod B, thereby ensuring that the ball head buckle is stuck in the installation hole and ensuring the stability of the connection between the ball head buckle and the connecting rod B.
