[0010] Optionally, the locking member is installed at the rotational connection between the first connecting rod and the second connecting rod; when the first connecting rod and the second connecting rod are parallel to each other, the locking member is locked on the fixing column.

[0011] Optionally, the locking member is an elastic member, and when the length directions of the first connecting rod and the second connecting rod are parallel to each other, the locking member contacts and is compressed against an outer peripheral surface of the fixing column.

[0012] Optionally, the first connecting rod is connected to the fixed column through a first rotating shaft, and a strip groove is provided on the outer circumferential surface of the fixed column, and the first rotating shaft passes through the strip groove and can move up and down in the strip groove; the first rotating shaft is above the movable column, and a spring is installed between the bottom of the first inner cavity and the first rotating shaft; a second inner cavity is provided at the upper end of the movable column, the first inner cavity and the second inner cavity are connected, the second connecting rod is connected to the movable column through a second rotating shaft, and the second rotating shaft passes through the movable column; the first rotating shaft and the second rotating shaft are connected by a tension spring.

[0016] As described above, the braking device of the automobile assembly trolley of the utility model has at least the following beneficial effects:

[0017] 1. The braking device of the automobile assembly trolley is connected to the automobile assembly trolley through a brake block and a telescopic component, and when the telescopic component is extended outward to drive the brake block to press against the ground, the locking member is designed to lock the telescopic component, so that when the automobile assembly production workshop adjusts the production line, when the operator moves the automobile assembly trolley, in addition to using the wheel locking mechanism to control the braking of the automobile assembly trolley, the operator can also use the braking device of the present application to further limit the automobile assembly trolley to a suitable position in the workshop; and because the telescopic component of the braking device is connected to the automobile assembly trolley, the braking device is still applicable to non-wheeled automobile assembly trolleys; thereby solving the problem that the wheel locking type braking device in the prior art has insufficient braking force and cannot be applied to non-wheeled automobile assembly trolleys.

[0018] 2. During use of the braking device of the automobile assembly trolley, as the first connecting rod and the second connecting rod rotate, when the second connecting rod drives the movable column to slide to the bottom, that is, the first connecting rod and the second connecting rod are parallel to each other, the locking member is installed at the rotation connection between the first connecting rod and the second connecting rod, and the locking member is directly locked on the fixed column, so that the first connecting rod and the second connecting rod cannot rotate, and the movable column will not slide again, thereby ensuring the braking function of the brake block at the lower end of the movable column on the automobile assembly trolley.

The braking device of the automobile assembly trolley is designed with a connection relationship between the first rotating shaft, the second rotating shaft, the spring, the tension spring fixed column and the rotating column. When the operator needs to move the automobile assembly trolley, the operator only needs to bend the connecting rod component to disengage the locking part and the fixing part. The movable column retracts under the action of the tension spring, driving the brake block to disengage from the ground, thereby realizing the release of the automobile assembly trolley by the braking device. There is no need to design additional components outside the fixed column to control the state of the braking device when it is released, and the structural space of the existing components is fully utilized. At the same time, due to the design of the spring, a buffer is provided for the up and down movement of the first rotating shaft, thereby improving the stability of the entire device.

DETAILED DESCRIPTION

[0026] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0027] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0028] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0029] See also Figure 1 and Figure 2 The utility model provides a braking device for an automobile assembly trolley, comprising a brake block 1, wherein the brake block 1 and the automobile assembly trolley are connected via a telescopic component 2; the telescopic component 2 is extended outward by the driving of a connecting rod component 3, and the extension of the telescopic component 2 drives the brake block 1 to press against the ground, and friction is generated between the brake block 1 and the ground, thereby preventing the automobile assembly trolley from moving and realizing the braking function of the braking device; in order to prevent the telescopic component 2 from retracting and affecting the braking effect during braking, a locking member 4 is installed on the connecting rod component 3, and when the telescopic component 2 is extended outward, the locking member 4 locks the telescopic component 2 to ensure the braking effect of the braking device.

[0030] Through the above design, when the automobile assembly production workshop adjusts the production line, when the operator moves the automobile assembly trolley, in addition to using the wheel locking mechanism to control the braking of the automobile assembly trolley, the operator can also use the braking device of the present application to further limit the automobile assembly trolley to a suitable position in the workshop; and because the telescopic component 2 of the braking device is connected to the automobile assembly trolley, the braking device is still applicable to non-wheeled automobile assembly trolleys; thereby solving the problem of insufficient braking force of the wheel locking type braking device in the prior art and the inability to be applied to non-wheeled automobile assembly trolleys.

[0031] In another embodiment, see Figure 2The telescopic component 2 includes a fixed column 21 and a movable column 22. The fixed column 21 is fixedly connected to the automobile assembly trolley; the upper end of the movable column 22 is slidably installed on the fixed column 21, and the brake block 1 is fixedly installed on the lower end of the movable column 22. The connecting rod component 3 drives the movable column 22 to slide on the fixed column 21. This embodiment provides a specific structural form of the telescopic component 2. The extension and retraction functions of the telescopic component 2 are realized by sliding the movable column 22 along the fixed column 21. The movable column 22 is powered by the connecting rod component 3. The entire structural form is simple. The operator applies external force to the connecting rod component 3 to drive the movement of the movable column 22.

[0032] In another embodiment, see Figure 2 and Figure 3 The lower end of the fixed column 21 is provided with a first inner cavity, and the upper end of the movable column 22 is slidably installed in the first inner cavity. The extension and contraction movement of the telescopic component 2 is the sliding movement of the movable column 22 in the first inner cavity. Designers can also use a method of setting a sliding track on the outer circumference of the fixed column 21 to achieve the sliding of the movable column 22 on the fixed column 21, but it is obvious that the utility model adopts the method of setting the first inner cavity at the lower end of the fixed column 21, which is simpler in structure, occupies less space, and the sliding process of the movable column 22 is more stable than the method of designing a sliding track on the outer circumference of the fixed column 21.

[0033] In another embodiment, see Figure 1 and Figure 2 The connecting rod component 3 includes a first connecting rod 31 and a second connecting rod 32; the upper end of the first connecting rod 31 is rotatably connected to the fixed column 21; the lower end of the first connecting rod 31 is rotatably connected to the upper end of the second connecting rod 32, and the lower end of the second connecting rod 32 is rotatably connected to the movable column 22; the operator realizes the rotation of the first connecting rod 31 and the second connecting rod 32 by bending the first connecting rod 31 or the second connecting rod 32; when the second connecting rod 32 rotates upward, it will move the movable column 22 upward; when the second connecting rod 32 rotates downward, it will move the movable column 22 downward; as the movable column 22 moves up and down, the extension and retraction functions of the entire telescopic component 2 are realized.

[0034] like Figure 1 and Figure 2 As shown, the first connecting rod 31 is symmetrically distributed on both sides of the telescopic part 2, and the second connecting rod 32 is also symmetrically distributed on both sides of the telescopic part 2. The first connecting rod 31 and the second connecting rod 32 are designed to be symmetrically shaped and distributed on both sides of the telescopic part 2, which fully ensures the stability of the first connecting rod 31 and the second connecting rod 32 when rotating, that is, ensures the stability of the entire connecting rod part 3 when driving the movable column 22 to move.

[0035] In another embodiment, see Figure 1 and Figure 2 The locking piece 4 is installed at the rotation connection between the first connecting rod 31 and the second connecting rod 32; when the second connecting rod 32 rotates downward, that is, the first connecting rod 31 and the second connecting rod 32 are parallel to each other, when the movable column 22 extends outward from the fixed column 21 to the lowest point, the locking piece 4 is locked on the fixed column 21, and the first connecting rod 31 and the second connecting rod 32 are no longer allowed to rotate, thereby fixing the position of the movable column 22, preventing the movable column 22 from retracting into the fixed column 21 during braking, affecting the braking effect.

[0036] In another embodiment, see Figure 2 The locking member 4 is an elastic member, for example, rubber is selected to make the elastic member, and the rubber elastic member is also provided with convex patterns or protrusions. When the length directions of the first connecting rod 31 and the second connecting rod 32 are parallel to each other, that is, when the movable column 22 extends outward from the fixed column 21 to the lowest point, the locking member 4 and the outer peripheral surface of the fixed column 21 are in contact and compressed, and the locking member 4 and the outer peripheral surface of the fixed column 21 generate friction, which prevents the first connecting rod 31 and the second connecting rod 32 from continuing to rotate, that is, the second connecting rod 32 can no longer drive the movable column 22 to move, thereby ensuring the contact between the brake block 1 and the ground, that is, ensuring the braking effect of the device.

[0037] like Figure 2 As shown, the locking member 4 can also be symmetrically arranged on both sides of the telescopic component 2 to ensure the stability of the connecting rod component 3 when it is locked.

[0038] In another embodiment, see Figure 2The first connecting rod 31 is connected to the fixed column 21 through the first rotating shaft 33. A strip groove 212 is provided on the outer peripheral surface of the fixed column 21. The first rotating shaft 33 passes through the strip groove 212 and can move up and down in the strip groove 212; the first rotating shaft 33 is above the movable column 22, and a spring 5 is installed between the bottom of the first inner cavity and the first rotating shaft 33; a second inner cavity 221 is provided at the upper end of the movable column 22, and the first inner cavity and the second inner cavity 221 are connected. The second connecting rod 32 is connected to the movable column 22 through the second rotating shaft 34, and the second rotating shaft 34 passes through the movable column 22; the first rotating shaft 33 and the second rotating shaft 34 are connected by a tension spring 6. In this embodiment, the connection relationship between the first rotating shaft 33, the second rotating shaft 34, the spring 5, the tension spring 6, the fixed column 21 and the rotating column is designed. When the operator needs to move the automobile assembly trolley, the operator only needs to bend the connecting rod component 3 to disengage the locking member 4 from the fixing member, and the movable column 22 retracts under the action of the tension spring 6, driving the brake block 1 to disengage from the ground, thereby realizing the release of the automobile assembly trolley by the braking device, without the need to design additional components outside the fixed column 21 to control the state of the braking device when it is released, thereby making full use of the structural space of the existing components; at the same time, due to the design of the spring 5, a buffer is provided for the up and down movement of the first rotating shaft 33, thereby improving the stability of the entire device.

[0039] In another embodiment, see Figure 1 A foot pedal 7 is installed on the second connecting rod 32. When the automobile assembly trolley needs to be braked, the operator steps on the foot pedal 7 to rotate the first connecting rod 31 and the second connecting rod 32 to their normal positions, and the locking member 4 locks the fixing column 21 to achieve the braking effect of the device.

[0040] In another embodiment, see Figure 1 and Figure 4 A handle 8 is installed on the first connecting rod 31. When the automobile assembly trolley needs to be released, the operator manually pulls the handle 8, the locking member 4 and the outer peripheral surface of the fixed column 21 are out of contact, and under the action of the tension spring 6, the first connecting rod 31 and the second connecting rod 32 rotate to a mutually perpendicular position, and the movable column 22 retracts into the fixed column 21, driving the brake block 1 to be out of contact with the ground, thereby achieving the purpose of release.

[0041] In another embodiment, see Figure 1 The brake block 1 is a disc made of rubber. The bottom surface of the brake block 1 is provided with convex patterns and protrusions, which increase the friction when the brake block 1 contacts the ground. Rubber is cheap. Compared with metal materials, the cost of using rubber as the manufacturing material is lower. In addition, during the braking process, the rubber brake block 1 will not damage the ground of the assembly workshop.

[0042] In other embodiments, Figure 1 As shown, a connecting plate 9 is fixedly installed on the upper end of the fixing column 21, and the connecting plate 9 is fixedly installed on the bottom surface of the automobile assembly trolley by means of bolts. A connecting plate 9 is fixedly installed on the upper end of the fixing column 21, and then the connecting plate 9 is fixedly connected to the bottom surface of the automobile assembly trolley. This makes the installation more secure, and the fixing method of the bolts facilitates subsequent disassembly and maintenance.

[0043] In summary, the utility model is designed such that the brake block 1 and the automobile assembly trolley are connected by the telescopic component 2, and when the telescopic component 2 is extended to drive the brake block 1 to press against the ground, the locking member 4 locks the telescopic component 2, so that when the automobile assembly production workshop adjusts the production line, when the operator moves the automobile assembly trolley, the operator can use the braking device of the present application to further limit the automobile assembly trolley to a suitable position in the workshop in addition to using the wheel locking mechanism to control the braking of the automobile assembly trolley; and because the telescopic component 2 of the present braking device is connected to the automobile assembly trolley, the present braking device is still applicable to non-wheeled automobile assembly trolleys; thereby solving the problem that the wheel locking type braking device in the prior art has insufficient braking force and cannot be applied to non-wheeled automobile assembly trolleys. At the same time, through the design of the connection relationship between the first rotating shaft 33, the second rotating shaft 34, the spring 5, the tension spring 6, the fixed column 21 and the rotating column, when the operator needs to move the automobile assembly trolley, the operator only needs to bend the connecting rod component 3 to disengage the locking member 4 from the fixed member, and the movable column 22 retracts under the action of the tension spring 6, driving the brake block 1 to disengage from the ground, thereby realizing the release of the automobile assembly trolley by the braking device, without the need to design additional components outside the fixed column 21 to control the state of the braking device when it is released, and making full use of the structural space of the existing components; at the same time, because of the design of the spring 5, a buffer is provided for the up and down movement of the first rotating shaft 33, thereby improving the stability of the entire device. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
