Description

Technical Field

[0001] This utility model relates to the field of automotive tie rod technology, specifically a horizontal tie rod for new energy vehicles with anti-detachment effect. Background Technology

[0002] The tie rods in automobiles are mainly used to control wheel rotation. The steering tie rods at both ends of the tie rods are connected to the wheels, allowing for flexible control of wheel steering. The steering tie rods at both ends of the tie rods are connected to the wheels through ball joints, and grease ensures the smooth movement of the ball joints inside the tie rods.

[0003] Currently, some ball joints are covered with dust covers to prevent grease from leaking out and dust from entering. However, after long-term use, cracks or even breakage may appear on the surface of the dust covers. In this case, grease leaks out, and dry friction between the ball joint and the steering tie rod can easily cause the ball joint to detach. The tie rod may then fall off while the vehicle is in motion and collide with the ground, which can easily cause damage. In addition, when a tie rod that has detached from one end hits the ground and bounces back, it may hit the battery at the bottom of a new energy vehicle, posing a greater threat to the driver's life. Utility Model Content

[0004] The purpose of this invention is to provide a new energy vehicle horizontal and vertical tie rod with anti-detachment effect to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy vehicle tie rod with anti-detachment effect, comprising a tie rod body, a steering tie rod body installed at both ends of the tie rod body, a ball head movably sleeved inside the steering tie rod body, a ball rod fixedly connected to the top of the ball head, a collar slidably sleeved on the surface of the ball rod, and a dust cover sleeved on the surface of the ball rod, and further comprising:

[0006] A positioning mechanism that can be detachably connected to the surface of the cue stick, with reinforcing plates installed on the surfaces of both positioning mechanisms;

[0007] The guide mechanism installed between the reinforcing plates includes a hollow cylinder disposed between the two reinforcing plates. A U-shaped frame is fixedly sleeved on the surface of the hollow cylinder, and a connecting mechanism that can rotate with the steering tie rod body is installed on the surface of the U-shaped frame.

[0008] Preferably, the positioning mechanism includes two positioning rods that movably pass through the ball. One end of each positioning rod is fixedly connected to a rotating rod. The other end of one positioning rod is provided with a threaded groove, and the other end of the other positioning rod is fixedly connected to a threaded cylinder. The threaded cylinder is threadedly connected to the threaded groove, and the reinforcing plate is rotatably sleeved on the surface of the positioning rod.

[0009] Preferably, a light rod is fixedly connected to the other end of one side positioning rod, and a groove is provided at the other end of the other side positioning rod, with the surface of the light rod fitting against the inner wall of the groove.

[0010] Preferably, a guide rod is fixedly connected to one end of each of the two reinforcing plates. A limit rod is fixedly connected to one end of one guide rod, and a limit groove is formed at one end of the other guide rod. The surface of the limit rod is in contact with the inner wall of the limit groove, and the guide rod slides through the hollow cylinder.

[0011] Preferably, a ring is fixedly sleeved on the surface of the guide rod, and the ring is in contact with the inner wall of the hollow cylinder.

[0012] Preferably, the connecting mechanism includes a vertical block rotatably sleeved on the surface of the C-shaped frame, a rubber sleeve detachably connected to the surface of the vertical block, and through grooves opened on the surfaces of both the vertical block and the rubber sleeve, with a connecting rod detachably connected inside the through grooves, and the rubber sleeve sleeved on the surface of the steering tie rod body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the cooperation of the connecting mechanism and the steering tie rod body, can control the falling height of the steering tie rod body when the ball joint detaches from inside the steering tie rod body, preventing one end of the steering tie rod body from colliding with the ground. The positioning mechanism, reinforcing plate, and guiding mechanism can work with the horizontal tie rod body and the steering tie rod body to adjust the angle, avoiding direct damage to the horizontal tie rod body and the steering tie rod body caused by the rigid connection, reducing losses. It solves the problem that when the connection between the steering tie rod and the ball joint on both sides of some horizontal tie rods detaches, one end of the steering tie rod falls directly and hits the ground and bounces back, which not only easily damages itself, but also threatens the battery under the car.

[0023] 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.

[0024] Please see Figure 1-7 As shown, a new energy vehicle tie rod with anti-detachment effect includes a tie rod body 1, a steering tie rod body 2 installed at both ends of the tie rod body 1, a ball joint 3 movably sleeved inside the steering tie rod body 2, a ball rod 4 fixedly connected to the top of the ball joint 3, a collar 5 slidably sleeved on the surface of the ball rod 4, and a dust cover 6 sleeved on the surface of the ball rod 4. The dust cover 6 can protect the lubricant and the ball joint 3, ensuring the smoothness of the ball joint 3 when moving inside the steering tie rod body 2. After the operator connects the ball rod 4 to the wheel, the collar 5 is sleeved on the ball rod 4. A positioning mechanism 7 is detachably connected to the surface of the ball rod 4. The positioning mechanism 7 includes two movable parts that pass through the ball rod 4. The positioning rod 71 has a rotating rod 72 fixedly connected to one end. The other end of one positioning rod 71 has a threaded groove 73 and is fixedly connected to a smooth rod 75. The other end of the other positioning rod 71 has a groove 76 and is fixedly connected to a threaded cylinder 74. The threaded cylinder 74 is threadedly connected to the threaded groove 73. The surface of the smooth rod 75 fits against the inner wall of the groove 76. After the operator passes the two positioning rods 71 ​​through both sides of the ball rod 4, one positioning rod 71 can be rotated. At this time, the threaded cylinder 74 and the threaded groove 73 cooperate, and the two positioning rods 71 ​​are connected. At the same time, the smooth rod 75 extends into the interior of the groove 76, which can strengthen the stability of the connection of the positioning rods 71.

[0025] The positioning mechanism 7 is installed on the cue stick 4 to fix the position of the cue stick 4 and the collar 5. Reinforcing plates 8 are installed on the surfaces of both sides of the positioning mechanism 7. The reinforcing plates 8 are rotatably sleeved on the surface of the positioning rod 71. A guide mechanism 9 is installed between the two reinforcing plates 8. The guide mechanism 9 includes a hollow cylinder 91 disposed between the two reinforcing plates 8. A U-shaped frame 10 is fixedly sleeved on the surface of the hollow cylinder 91. A connecting mechanism 11 is installed on the surface of the U-shaped frame 10. The connecting mechanism 11 can connect the U-shaped frame 10 and the steering tie rod body 2. When the ball head 3 detaches from the interior of the steering tie rod body 2, the connecting mechanism 11 can connect the steering tie rod body 2 and the U-shaped frame 10, preventing the steering tie rod body 2 from detaching. The connecting mechanism 11 includes a vertical block 111 rotatably sleeved on the surface of the C-shaped frame 10. A rubber sleeve 112 is detachably connected to the surface of the vertical block 111. Both the surface of the vertical block 111 and the rubber sleeve 112 are provided with through grooves. A connecting rod 113 is detachably connected inside the through grooves. The rubber sleeve 112 is sleeved on the surface of the steering tie rod body 2. After the rubber sleeve 112 is engaged with the vertical block 111, the operator passes the connecting rod 113 through the through groove. The connecting rod 113 can connect the vertical block 111 and the rubber sleeve 112. At this time, the connecting mechanism 11 can support the steering tie rod body 2 and prevent the ball head 3 from falling out of the inside of the steering tie rod body 2, so that the steering tie rod body 2 will fall directly.

[0026] One end of each of the two reinforcing plates 8 is fixedly connected to a guide rod 92. One end of one guide rod 92 is fixedly connected to a limiting rod 93, and one end of the other guide rod 92 is provided with a limiting groove 94. The surface of the limiting rod 93 is in contact with the inner wall of the limiting groove 94. When the two positioning mechanisms 7 are connected, the reinforcing plate 8 can drive the two guide rods 92 to move towards each other. At this time, the limiting rod 93 is in contact with the limiting groove 94, and the guide rod 92 slides through the hollow cylinder 91. The guide rod 92 can move stably inside the hollow cylinder 91. A ring 95 is fixedly sleeved on the surface of the guide rod 92. The ring 95 is in contact with the inner wall of the hollow cylinder 91. The ring 95 can limit the range of movement of the guide rod 92 and prevent the guide rod 92 from detaching from the hollow cylinder 91.

[0027] Working principle: When the steering tie rod body 2 moves, it can drive the wheel to move through the ball joint 3 and the ball rod 4. The dust cover 6 is broken due to long-term use, and the internal grease is leaking out. The ball joint 3 and the steering tie rod body 2 continue to dry rub against each other. When the ball joint 3 falls out of the steering tie rod body 2, the connecting mechanism 11 pulls it to prevent the steering tie rod body 2 from falling directly, thereby reducing the damage to the steering tie rod body 2. The operator turns the rotating rod 72 to drive the positioning rod 71 to rotate. After the connection between the threaded groove 73 and the threaded cylinder 74 is released, the positioning mechanism 7 can be removed. The operator replaces the damaged dust cover 6. After the ball joint 3 is installed inside the steering tie rod body 2, the operator reinstalls the positioning mechanism 7 for subsequent use of the car steering.
