Description

Technical Field

[0001] This application relates to the field of automobile trunk structure, and in particular to a multifunctional limiting device for automobile trunk mat. Background Technology

[0002] The trunk of a car is the main place to store luggage and other items that people carry when traveling. However, in actual use, luggage and other items placed in the trunk may collide or tip over due to the car's acceleration or sudden braking.

[0003] Chinese Patent CN219857030U discloses a luggage stop bar, a limiting device, and a car trunk mat, used to lock in the car trunk to limit luggage. The luggage stop bar includes: a support cylinder with a sealing cover detachably connected to one end; a button slidably connected to one end of the support cylinder; a sliding rod slidably connected inside the support cylinder, with a locking block connected to one end of the sliding rod, the sliding rod being located between the button and the locking block, and the locking block being located outside the support cylinder; two luggage stop bars are provided, and two guide rails are arranged in parallel, with each luggage stop bar corresponding to one guide rail, and a limiting rod connecting the two luggage stop bars.

[0004] During use, the limiting rods are effective at restricting large or tall items such as luggage, but less effective at restricting short items that are stacked together. When a car accelerates or brakes suddenly, small items can still slide out through the space between the two limiting rods, and these items are easily damaged, which is problematic. Utility Model Content

[0005] In order to improve the problem of poor restriction effect on small-volume items in the above-mentioned technology, this application provides a multi-functional limiting device for car trunk mats.

[0006] The multi-functional limiting device for a car trunk mat provided in this application adopts the following technical solution: A multifunctional limiting device for a car trunk mat includes a support cylinder and a retractable rod. The support cylinder is symmetrically arranged at both ends of the retractable rod. Limiting rods are provided at the top and bottom of the support cylinder. The end of the limiting rod facing away from the support cylinder is slidably sleeved on the end of the retractable rod. A U-shaped groove plate is provided on the limiting rod. A limiting component for blocking items is provided between the two limiting rods at the top and bottom of the support cylinder.

[0007] By adopting the above technical solution, the limiting component compensates for the obstruction space between the two limiting rods at the top and bottom of the support cylinder, thereby reducing the possibility that small items may slide out through the space between the two limiting rods when the car accelerates or brakes suddenly.

[0008] Optionally, the limiting component includes a baffle disposed between the two limiting rods on the support cylinder, the side of the baffle being inserted into the U-shaped concave side of the groove plate.

[0009] By adopting the above technical solution, the user inserts both sides of the baffle into the U-shaped concave side of the slot plate, so that the baffle blocks the space between the two limiting rods, thereby reducing the possibility of small items sliding out of the space between the two limiting rods.

[0010] Optionally, the baffle plate is provided with several weight-reduction holes.

[0011] By adopting the above technical solution, while ensuring the structural strength of the baffle itself, opening a large number of weight-reducing holes on the baffle can greatly reduce the weight of the baffle, thereby reducing the fuel consumption cost of the car.

[0012] Optionally, an intermediate plate is arranged between the two baffles. The intermediate plate has several oblong holes. Fastening bolts are inserted into the weight-reducing holes of the baffles. The fastening bolts pass through the oblong holes of the intermediate plate and are fastened with fixing nuts. The fixing nuts press the intermediate plate tightly against the baffles.

[0013] By adopting the above technical solution, for cars with a wider rear end, the distance between the support cylinders at both ends of the retractable bar will increase, resulting in a larger gap between the two baffles. At this time, the user can fix the middle plate between the two baffles by fixing nuts and fastening bolts, thereby blocking the space between the two baffles by the middle plate, thus reducing the possibility of small items sliding out through the space between the two baffles.

[0014] Optionally, one of the support cylinders has an extension plate on its baffle, and the other support cylinder has a slot for inserting the extension plate on its baffle.

[0015] By adopting the above technical solution, as the distance between the two baffles increases, the expansion plate slides to always block the space between the two baffles, thereby reducing the possibility of small items sliding out of the space between the two baffles.

[0016] Optionally, the limiting component includes multiple limiting strips slidably disposed on the groove plate, the multiple limiting strips being arranged along the length direction of the groove plate, the groove plate being located at both ends of the limiting strips, and an elastic pull rope being provided between each two adjacent limiting strips. One limiting strip closer to the support cylinder is fixedly disposed on the groove plate, and a locking plate is provided at the end of the groove plate away from the support cylinder. A limiting member is provided on the locking plate, and the limiting member is used to limit the position of the limiting strip farthest from the support cylinder.

[0017] By adopting the above technical solution, under the action of the elastic pull rope, the limiting member restricts the position of the limiting strip furthest from the support cylinder, so that multiple limiting strips are evenly distributed along the length direction of the groove plate, thereby achieving the effect of blocking small-volume items.

[0018] Optionally, the limiting element includes a locking pin slidably disposed on the locking plate, a locking hole for the locking pin to pass through is provided on the groove plate, a ring plate is provided on the locking pin, and a compression spring is provided between the ring plate and the locking plate to press the ring plate tightly on the groove plate.

[0019] By adopting the above technical solution, the compression spring pushes the locking pin into the locking hole on the groove plate through the ring plate. At this time, the limiting plate that is furthest from the support cylinder will be blocked by the locking pin. At the same time, the elastic pull rope is stretched. Moreover, the user can see the position of different items through the gap between two adjacent limiting plates, which makes it convenient for the user to take the items.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting component compensates for the obstruction space between the two limiting rods at the top and bottom of the support cylinder, thereby reducing the possibility that small items may slide out through the space between the two limiting rods when the car accelerates or brakes suddenly. 2. The user inserts both sides of the baffle into the U-shaped concave side of the slot plate, so that the baffle blocks the space between the two limiting rods, thereby reducing the possibility of small items sliding out through the space between the two limiting rods; 3. For cars with a wider rear end, the distance between the support cylinders at both ends of the retractable bar will increase, resulting in a larger gap between the two baffles. In this case, the user can fix the middle plate between the two baffles by fixing nuts and fastening bolts, thereby blocking the space between the two baffles and reducing the possibility of small items sliding out through the space between the two baffles. 4. The compression spring pushes the locking pin into the locking hole on the groove plate through the ring plate. At this time, the limiting plate farthest from the support cylinder will be blocked by the locking pin. At the same time, the elastic pull rope is stretched. Moreover, the user can see the position of different items through the gap between two adjacent limiting plates, which makes it convenient for the user to take the items. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0028] This application discloses a multi-functional limiting device for a car trunk mat.

[0029] Example 1 Reference Figure 1 A multi-functional limiting device for a car trunk mat includes a support cylinder 1 and a retractable rod 2. The support cylinder 1 is symmetrically arranged at both ends of the retractable rod 2. A limiting rod 3 is bolted to the top and bottom of the support cylinder 1. The end of the limiting rod 3 facing away from the support cylinder 1 is slidably sleeved on the end of the retractable rod 2.

[0030] Reference Figure 1The limiting rod 3 has an integrally formed U-shaped groove plate 4. The U-shaped open ends of the groove plates 4 on the two limiting rods 3 at the top and bottom of the support cylinder 1 are opposite each other. A limiting component for blocking items is arranged between the two limiting rods 3 at the top and bottom of the support cylinder 1.

[0031] Reference Figure 1 The limiting component includes a baffle 51 arranged between two limiting rods 3 on the support cylinder 1. The side of the baffle 51 is inserted into the U-shaped concave side of the groove plate 4, and several weight reduction holes 6 are provided on the baffle 51.

[0032] The implementation principle of Example 1 is as follows: When the car is accelerating or braking suddenly, the baffle 51 blocks the space between the two limiting rods 3. At this time, small items cannot slide out through the space between the two limiting rods 3, thereby reducing the possibility of items sliding out and getting damaged.

[0033] Example 2 refer to Figure 2 The difference between this embodiment and embodiment 1 is that: an intermediate plate 7 is arranged between the two baffles 51, and a number of waist-shaped holes 8 are opened on the intermediate plate 7. Fastening bolts 9 are inserted into the weight reduction holes 6 of the baffles 51, the fastening bolts 9 pass through the waist-shaped holes 8 on the intermediate plate 7, and a fixing nut 10 is bolted to the fastening bolts 9. The fixing nut 10 presses the intermediate plate 7 tightly onto the baffles 51.

[0034] The implementation principle of Example 2 is as follows: For cars with a wider rear size, the user can increase the distance between the two support cylinders 1 by pulling the limiting rod 3 at the end of the retractable rod 2, and then fix the middle plate 7 between the two baffles 51 by fastening the bolt 9 and fixing nut 10, so as to adapt to cars with different widths. At the same time, the middle plate 7 ensures that small items cannot slide out between the two baffles 51.

[0035] Example 3 refer to Figure 3 The difference between this embodiment and embodiment 1 is that: an extension plate 11 is welded on the baffle 51 on one of the support cylinders 1, and a slot 12 for inserting the extension plate 11 is provided on the baffle 51 on the other support cylinder 1.

[0036] The implementation principle of Example 3 is as follows: when the distance between the two support cylinders 1 changes, the space between the two baffles 51 can be automatically blocked by the sliding of the extension plate 11, which greatly reduces the difficulty of adjustment for the user.

[0037] Example 4 refer to Figure 4The difference between this embodiment and embodiment 1 is that the limiting component includes multiple limiting strips 52 that are slidably arranged on the groove plate 4. The multiple limiting strips 52 are arranged along the length direction of the groove plate 4. The groove plate 4 is located at both ends of the length direction of the limiting strips 52. An elastic pull rope 53 is attached between each two adjacent limiting strips 52. The elastic pull rope 53 can be an elastic rope in the prior art.

[0038] refer to Figure 4 and Figure 5 A limiting strip 52 near the support cylinder 1 is bolted to the groove plate 4. A door-shaped locking plate 54 is welded to the end of the groove plate 4 away from the support cylinder 1. A limiting member 55 is arranged on the locking plate 54. The limiting member 55 is used to limit the position of the limiting strip 52 farthest from the support cylinder 1.

[0039] Reference Figure 5 The limiting member 55 includes a locking pin 551 that slides through the locking plate 54. The groove plate 4 has a locking hole 552 for the locking pin 551 to pass through. A ring plate 553 is welded to the locking pin 551. A compression spring 554 supports the ring plate 553 and the locking plate 54. The compression spring 554 is used to press the ring plate 553 tightly onto the groove plate 4.

[0040] The implementation principle of Example 4 is as follows: When the user pulls the locking pin 551, the compression spring 554 is compressed, and the side of the locking pin 551 facing away from the compression spring 554 moves away from the U-shaped concave side on the slot plate 4. Then, the user moves the limiting strip 52 furthest from the support cylinder 1 to the end of the slot plate 4 away from the support cylinder 1. Subsequently, the user releases the locking pin 551, the compression spring 554 returns to its original deformation, and the locking pin 551 is reinserted into the locking hole 552 on the slot plate 4.

[0041] Under the restoring deformation force of the elastic pull rope 53, the side of the limiting strip 52 furthest from the support cylinder 1 will abut against the locking pin 551. At this time, multiple limiting strips 52 are evenly distributed along the length of the groove plate 4, thereby achieving the function of blocking small items. At the same time, the user can see the position of different items through the gap between two adjacent limiting strips 52, which makes it convenient for the user to take the items.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
