Description

Technical Field

[0001] The invention belongs to the field of automobile cameras, and in particular relates to a camera folder for an automobile. Background Art

[0002] With the vigorous development of the automobile industry, there are more and more vehicles, which has brought a lot of convenience to people's lives and transportation. However, due to the high speed of cars, there are more and more traffic accidents on the road. In many traffic accidents, the descriptions of the accidents by both parties are inconsistent, which often increases the difficulty for traffic police to determine the responsibility. Therefore, in order to restore the authenticity of traffic accidents and make it easier for traffic police to determine the responsibility for the accidents, monitoring systems such as cameras are installed on cars.

[0003] In order to ensure the integrity of the driving process, the camera needs to have the function of steering and folding. One way is to directly purchase a camera with steering and folding function and install it on the car, but this type of camera has poor compatibility with the car, and it is easy to interfere with other parts of the car during rotation. It also cannot monitor the important camera areas of the car. The other way is to design a folder specifically for installing the camera on the car according to the use requirements of the car. During the use of the folder, due to suspension or other usage conditions, the folder should be made of lightweight materials as much as possible, such as plastic. However, the corresponding lightweight materials have low strength and poor impact resistance. When folding quickly, it is easy to be damaged by instantaneous impact, which is not conducive to the long-term use of the folder. Summary of the Invention

[0004] In view of the above-mentioned shortcomings, the present invention proposes a camera folder for automobiles that can reduce damage to the folder during rapid folding and effectively increase the service life of the folder.

[0005] The technical solution adopted by the present invention to solve the above problems is: a camera folding device for a car, comprising a shell, a mounting shaft, a driving gear, an adjusting connector, a base and a pedestal, wherein the base is fixedly connected to the shell, and the base is fixedly connected to the mounting shaft; under electric drive conditions, the driving gear and the base rotate synchronously; the adjusting connector is connected to the driving gear for circumferential limited movement, and along the axial direction, one side of the adjusting connector is connected to the driving gear for limited movement, and an adjusting spring is provided between the other side of the adjusting connector and the driving gear; the shell is arranged above the adjusting connector, and a plurality of limiting inclined blocks are provided on a side of the shell close to the adjusting connector, and one side of the limiting inclined block along the circumferential direction is an inclined surface, and the other side is a vertical surface; the adjusting connector is provided with a plurality of limiting abutment blocks, and the arc between two adjacent limiting inclined blocks is the movement range of the limiting abutment block. During the folding process, the limiting abutment block moves from abutting against the vertical surface of one limiting inclined block to the inclined surface direction of another limiting inclined block.

[0006] Compared with the prior art, the advantage of the present invention is that: during the rapid folding process, when the driving gear moves quickly into place, the limit abutment block on the adjustment connecting piece abuts against the inclined surface on the limit bevel block, and the adjustment connecting piece moves in the direction of the adjustment spring, squeezing the adjustment spring to form a deceleration and buffering effect of the driving gear, thereby avoiding damage to the connection between the driving gear and the transmission assembly due to inertia during continued rotation after the transmission assembly stops.

[0007] As an improvement, a limit hook is provided on the inner side of the driving gear, and a limit groove is provided on the adjusting connecting piece, and the limit hook is abutted against the bottom of the limit groove to realize the upward axial movement limit of the adjusting connecting piece. Through the improvement, the upward axial movement limit of the adjusting connecting piece is realized, and the situation in which the adjusting connecting piece is continuously abutted against the shell under the action of the adjusting spring is avoided, thereby avoiding the friction between the adjusting connecting piece and the shell during the rotation between the two limit bevel blocks, and avoiding the collision between the limit abutting block and the bottom end of the inclined surface of the limit bevel block during the rotation of the adjusting connecting piece. Because there is a corner at the connection between the bottom end of the limit bevel block and the shell, it is easy to be damaged under collision, thereby better protecting the use of the limit bevel block, and the design of the limit groove can avoid the limit hook protruding from the design requirements of the upper surface of the adjusting connecting piece, making the design flatter of the driving gear.

[0008] As an improvement, a circumferential limit block is provided on the inner side of the driving gear, and a circumferential limit groove is provided on the outer side of the adjusting connecting piece. The circumferential limit block and the circumferential limit groove are matched for circumferential limiting. Through the improvement, the synchronous rotation of the driving gear and the adjusting connecting piece is achieved.

[0009] As an improvement, a limit mounting plate is provided at one end of the mounting shaft close to the shell, and an abutment spring is provided between the limit mounting plate and the driving gear. The abutment spring ensures that the driving gear and the base are maintained in an axial abutment state, and the base and the base are maintained in an axial abutment state. Through the improvement, firstly, the elastic force of the abutment spring is utilized, and after wear between parts occurs, the gap formed by wear is eliminated under the action of the elastic force, so that the driving gear and the base, and the base and the base are always maintained in an abutment state, avoiding abnormal noise and errors during the folding process, and ensuring high precision and stability during the folding process.

[0010] As an improvement, the driving gear is provided with an adjustment spring groove for installing the adjustment spring and an abutment spring groove for installing the abutment spring. The adjustment spring groove and the abutment spring groove are arranged separately. Through the improvement, the elastic axiality of the adjustment spring and the abutment spring is guaranteed, thereby ensuring the adjustment stability of the adjustment spring and the elastic force stability of the abutment spring.

[0011] As an improvement, a connecting ring is provided at the bottom of the base, the upper end of the connecting ring is against the driving gear, and the lower end of the connecting ring is against the base, and the side of the driving gear close to the connecting ring is provided with a first connecting groove for the connecting ring to be embedded, and the side of the base close to the connecting ring is provided with a second connecting groove for the connecting ring to be embedded. Through the improvement, compared with the conventional spring-eliminating gap structure, the present invention has the function of eliminating two gaps with only one spring. Although the base is provided on the side of the connecting ring away from the driving gear, the design of the shaft limit mounting plate is used to transfer the elastic force point of the base to the side of the driving gear away from the connecting ring, thereby arranging an abutment spring between the base and the driving gear, so that the elastic force on one side of the abutment spring can be maintained. The springs on the other side ensure that the driving gear and the connecting ring are against each other, while the elastic force on the other side ensures that the base and the connecting ring are against each other. Compared with the design in which multiple springs act on the driving gear and the base respectively, the structure of the present invention occupies less space, has a more compact structure, and is more stable in force. The eliminated gap will not appear in other areas of the structure, and the tightness of the folder is always maintained. At the same time, the design of the abutting spring can also make the force of the folder more centralized. When the folder is used in an inclined position, the elastic force of the abutting spring ensures the friction between the driving gear and the connecting ring and the friction between the base and the connecting ring, which can reduce the unidirectional tilt deviation caused by gravity, and avoid the wear of the lower end of the tilt being much greater than the wear of the upper end of the tilt, thereby better ensuring the service life of the folder.

[0012] As an improvement, a first friction plate is provided in the first connecting groove, and the first friction plate is provided between the connecting ring and the driving gear. A second friction plate is provided in the second connecting groove, and the second friction plate is provided between the connecting ring and the base. Through the improvement, the design of the first friction plate can make the wear between the connecting ring and the driving gear concentrated on the first friction plate, thereby avoiding the wear of the connecting ring and the driving gear. During maintenance, only the first friction plate needs to be replaced, thereby ensuring the long-term use of the connecting ring and the driving gear. The first friction plate is provided in the first connecting groove to avoid the first friction plate from derailing, ensuring that the first friction plate is always provided between the driving gear and the connecting ring. The design of the second friction plate can make the wear between the connecting ring and the base concentrated on the second friction plate, thereby avoiding the wear of the connecting ring and the base. During maintenance, only the second friction plate needs to be replaced, thereby ensuring the long-term use of the connecting ring and the base. The second friction plate is provided in the second connecting groove to avoid the second friction plate from derailing, ensuring that the second friction plate is always provided between the base and the connecting ring.

[0013] As an improvement, the base is further provided with a base auxiliary inclined block on one side close to the base, and the base is provided with a base auxiliary inclined block on one side close to the base, and the base auxiliary inclined block has the same structure as the base auxiliary inclined block, and both the base auxiliary inclined block and the base auxiliary inclined block include a small slope inclined surface and a large slope inclined surface. When the limit abutment block moves along the inclined surface of the limit oblique block, the small slope inclined surface of the base auxiliary oblique block and the small slope inclined surface of the base auxiliary oblique block approach each other, and when the limit abutment block abuts against the vertical surface of the limit oblique block, the large slope inclined surface of the base auxiliary oblique block abuts against the large slope inclined surface of the base auxiliary oblique block. Through the improvement, during use, when the limit abutment block abuts against the limit oblique block, the limit abutment block performs relative movement. If the folding device is not in a good condition, the lifting device may be in a state of disrepair and the lifting of the lifting device may cause the lifting of the lifting device to a faulty state, and the lifting of the lifting device may cause the lifting of the lifting device to a faulty state, so that the lifting device can be effectively prevented from being dislodged from the lifting device.

[0014] As an improvement, a downward extension portion is provided at the lower end of the base, and the extension portion is provided on the outside of the base and wraps the base. Through the improvement, dust is prevented from entering between the bases.

[0015] As an improvement, a connecting tooth assembly is provided between the driving gear and the base. When the camera is electrically driven, the connecting tooth assembly ensures a fixed connection. When the camera is manually folded, the connecting tooth assembly is separated. Through the improvement, the camera needs to have the function of manual folding in some cases, so the driving gear needs to be connected and separated from the base under manual folding to avoid the rotation of the driving gear caused by manual folding.

[0023] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, a camera folder for a car includes a housing 1, a mounting shaft 2, a driving gear 3, an adjusting connector 4, a base 5 and a pedestal 6. The base 6 is fixedly connected to the housing 1, and the base 5 is fixedly connected to the mounting shaft 2. Under electric drive conditions, the driving gear 3 and the base 5 rotate synchronously. The adjusting connector 4 is circumferentially limited and movable connected to the driving gear 3. Along the axial direction, one side of the adjusting connector 4 is limited and movable connected to the driving gear 3. An adjusting spring 7 is provided between the other side of the adjusting connector 4 and the driving gear 3. The housing 1 is arranged above the adjusting connector 4, and the housing 1 is close to the adjusting connector. Three limiting oblique blocks 1.1 are provided on one side of the component 4, and one side of the limiting oblique block 1.1 along the circumferential direction is an inclined surface, and the other side is a vertical surface. Three limiting abutment blocks 4.1 are provided on the adjusting connecting component 4, and the arc between two adjacent limiting oblique blocks 1.1 is the moving range of the limiting abutment block 4.1. In the unfolded state, the limiting abutment block 4.1 abuts against the vertical surface of one limiting oblique block 1.1, and the limiting abutment block 4.1 cannot move toward the vertical surface direction of one limiting oblique block 1.1. During the folding process, the limiting abutment block 4.1 moves from the position abutting against the vertical surface of one limiting oblique block 1.1 to the inclined surface direction of another limiting oblique block 1.1.

[0025] like Figure 3 As shown, a limit hook 3.1 is provided on the inner side of the driving gear 3, and a limit groove 4.2 is provided on the adjusting connecting member 4. The limit hook 3.1 is abutted against the bottom of the limit groove 4.2 to achieve the upward axial movement limit of the adjusting connecting member 4. A circumferential limit block 3.2 is provided on the inner side of the driving gear 3, and a circumferential limit groove 4.3 is provided on the outer side of the adjusting connecting member 4. The circumferential limit block 3.2 and the circumferential limit groove 4.3 are matched for circumferential limit.

[0026] like Figure 2 、 Figure 3 As shown, a limiting mounting piece 2.1 is provided at one end of the mounting shaft 2 close to the housing 1, and an abutment spring 8 is provided between the limiting mounting piece 2.1 and the driving gear 3. The abutment spring 8 ensures that the driving gear 3 and the base 6 are maintained in an axial abutment state, and the base 6 and the base 5 are maintained in an axial abutment state. An adjusting spring groove 3.3 for installing an adjusting spring 7 and an abutment spring groove 3.4 for installing an abutment spring 8 are provided in the driving gear 3, and the adjusting spring groove 3.3 and the abutment spring groove 3.4 are separately arranged.

[0027] like Figure 2As shown, a connecting ring 6.1 is provided at the bottom of the base 6, the upper end of the connecting ring 6.1 is abutted against the driving gear 3, and the lower end of the connecting ring 6.1 is abutted against the base 5, and the side of the driving gear 3 close to the connecting ring 6.1 is provided with a first connecting groove 3.5 for the connecting ring 6.1 to be embedded, and the side of the base 5 close to the connecting ring 6.1 is provided with a second connecting groove 5.1 for the connecting ring 6.1 to be embedded, a first friction plate 9 is provided in the first connecting groove 3.5, and the first friction plate 9 is provided between the connecting ring 6.1 and the driving gear 3, a second friction plate 10 is provided in the second connecting groove 5.1, and the second friction plate 10 is provided between the connecting ring 6.1 and the base 5, and the lower end of the base 6 is provided with a downward extension 6.3, and the extension 6.3 is provided on the outside of the base 5 and wraps the base 5.

[0028] like Figure 5 、 Figure 6 As shown, the base 6 is further provided with a base auxiliary inclined block 6.2 on the side close to the base 5, and the base 5 is provided with a base auxiliary inclined block 5.2 on the side close to the base 6. The structure of the base auxiliary inclined block 6.2 is the same as that of the base auxiliary inclined block 5.2. The base auxiliary inclined block 5.2 and the base auxiliary inclined block 6.2 both include a small slope inclined surface and a large slope inclined surface. When the limit abutment block 4.1 moves along the inclined surface of the limit oblique block 1.1, the small slope inclined surface of the base auxiliary oblique block 5.2 and the small slope inclined surface of the base auxiliary oblique block 6.2 approach each other. When the limit abutment block 4.1 abuts against the vertical surface of the limit oblique block 1.1, the large slope inclined surface of the base auxiliary oblique block 5.2 abuts against the large slope inclined surface of the base auxiliary oblique block 6.2.

[0029] A connecting gear assembly 11 is provided between the driving gear 3 and the base 5. When the camera is electrically driven, the connecting gear assembly 11 ensures a fixed connection. When the camera is manually folded, the connecting gear assembly 11 is separated.

[0030] The three abutment bevels and the three limiting abutment blocks 4.1 are arranged in a uniform array along the circumference. The interval between two adjacent abutment bevels is 120 degrees, and the meshing cycle of the connecting teeth on the connecting tooth assembly 11 is also 120 degrees. That is, when manually folding, after the connecting tooth assembly 11 is separated, it needs to rotate 120 degrees before the connecting tooth assembly 11 can be re-engaged, thereby ensuring the consistency of the camera folding angle. After manual folding, the electrically driven folding does not require re-reference positioning. Multiple meshing teeth are provided in each meshing cycle of the connecting tooth assembly 11 to ensure the strength of the meshing.

[0031] The lateral abutment slope of the connecting teeth on the connecting tooth assembly 11 is the same as the slope of the large slope of the base auxiliary inclined block 6.2 and the slope of the large slope of the base auxiliary inclined block 5.2. When manual folding is performed, the camera may be in a state where the vertical surface of the limit abutment block 4.1 and the limit inclined block 1.1 are abutted. At this time, manual folding is performed, and the base 5 and the base 6 rotate relative to each other. The large slope of the base auxiliary inclined block 6.2 and the large slope of the base auxiliary inclined block 5.2 rotate close to each other, and the base 5 is equivalent to the base 6 moving downward, which can assist the connecting tooth assembly 11 to separate.

[0032] During use, under the electric drive condition, the folder only keeps rotating, while under the manual drive condition, the folder lifting process will occur because of the need to separate the base 5 and the driving gear 3.

[0033] The above description is merely a description of the preferred embodiment of the present invention and is not to be construed as limiting the scope of the claims. The present invention is not limited to the above embodiment, and variations in the specific structure are permitted. Any variations within the scope of the independent claims of the present invention are also within the scope of protection of the present invention.
