Detailed Implementation

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] like Figure 1 - Figure 2As shown, a vehicle-mounted object fixing device comprises a crossbeam 1, a target object fixing assembly 3 and a supporting mechanism 4. The target object fixing assembly 3 is fixedly assembled on the supporting mechanism 4 for fixing target objects. The target object fixing assembly 3 comprises a clamping plate supporting plate 31, a clamping plate abutting plate 32 and a clamping block 33. The clamping plate supporting plate 31 and the clamping plate abutting plate 32 are oppositely arranged on the supporting mechanism 4 so as to form a clamping gap between the clamping plate supporting plate 31 and the clamping plate abutting plate 32. The clamping block 33 is arranged in the clamping gap. The clamping block 33 is connected with a clamping adjusting screw 34 at a side close to the clamping plate supporting plate 31. The clamping adjusting screw 34 is screwed through the clamping plate supporting plate 31 and connected with an adjusting handle 39 at an end away from the clamping block 33. The supporting mechanism 4 is movably assembled on the crossbeam 1.

[0061] The crossbeam 1 is the main supporting structure of the vehicle-mounted object fixing device. In use, the crossbeam 1 is placed on the walls of the vehicle compartment to support and connect other components, such as the crossbeam fixing mechanism 2, the supporting mechanism 4 and the target object fixing assembly 3. The crossbeam fixing mechanism 2 fixes the crossbeam 1 by abutting against the inner walls of the vehicle compartment. The supporting mechanism 4 drives the target object fixing assembly 3 to change position by being slidably arranged on the crossbeam 1. The target object fixing assembly 3 directly clamps objects in the vehicle compartment, thereby fixing the objects.

[0062] Moreover, since the crossbeam 1 spans the vehicle compartment and the supporting mechanism 4 is movably assembled on the crossbeam 1, the target object fixing assembly 3 supported by the supporting mechanism 4 can move across the vehicle compartment, thereby better adapting to the positions of target objects in the vehicle compartment.

[0063] Meanwhile, the target object fixing assembly 3 and the supporting mechanism 4 can be arranged in parallel on the crossbeam 1 in a corresponding number according to the specific number of objects to be fixed, without increasing other components, so that the device can meet the demand for fixing multiple objects.

[0064] As Figure 10 - Figure 12As shown, specifically, the clamping plate support plate 31 and the clamping plate abutting plate 32 are oppositely arranged on the support frame 41, and the clamping gap is formed between the two. The clamping plate support plate 31 is used to support the clamping adjusting screw 34 and the clamping block 33, and the clamping adjusting screw 34 and the clamping plate support plate 31 are threadedly connected, so that when the clamping adjusting screw 34 is rotated, the clamping adjusting screw 34 moves relative to the clamping plate support plate 31, thereby pushing the clamping block 33 to move in the clamping gap. In use, the part of the target object to be fixed is placed in the clamping gap. By rotating the clamping adjusting screw 34, the clamping block 33 can be pushed to abut against the target object, while the other side of the target object is abutted by the clamping plate abutting plate 32, so that the target object is clamped and fixed, and stable clamping and fixing of the target object is achieved through the self-locking property of the clamping adjusting screw 34.

[0065] Further, due to the different shapes of target objects, the clamping block 33 can be arranged in a shape corresponding to the clamped part of the target object, such as a circular arc shape, a strip shape, etc., and of course the clamping plate abutting plate 32 corresponding thereto can also be arranged in a corresponding shape according to the shape of the target object. Further, a buffer pad such as rubber can also be arranged on the side of the clamping block 33 and the clamping plate abutting plate 32 in contact with the target object. In this way, damage that may be caused during clamping and transportation can be reduced, and the friction can also be increased to increase the clamping effect.

[0066] Further, the clamping adjusting screw 34 is provided with an adjusting handle 39 at the end away from the clamping block 33. The adjusting handle 39 can facilitate the rotation of the clamping adjusting screw 34, so that the user can easily adjust the clamping block 33, and the force fed back to the hand through the adjusting handle 39 during clamping can be used to well judge whether the clamping is tight.

[0067] As shown in the drawings, Figure 12 Further, as shown, the clamping adjusting screw 34 is provided with a connecting ring 35 at the end inside the clamping gap, and the diameter of the connecting ring 35 is smaller than the diameter of the clamping adjusting screw 34, so that a step is formed between the connecting ring 35 and the clamping adjusting screw 34. The clamping adjusting screw 34 is provided with a mounting screw hole 36 in communication with the inside of the connecting ring 35, and the clamping block 33 is provided with a mounting through hole 37 in a stepped shape. The connecting ring 35 is connected into the small-diameter part of the mounting through hole 37, the mounting through hole 37 is provided with a mounting bolt 38 matched with the mounting screw hole 36, and the nut part of the mounting bolt 38 is matched with the large-diameter part of the mounting through hole 37.

[0068] The mounting through hole 37 is in T shape as a whole, and the side close to the clamping adjusting screw 34 and the connecting ring 35 is the small diameter part. The connecting ring 35 is inserted into the small diameter part of the mounting through hole 37, and can rotate or slide freely in the small diameter part of the mounting through hole 37. However, the diameter of the clamping adjusting screw 34 is larger than the diameter of the small diameter part of the mounting through hole 37, so that when the connecting ring 35 is inserted into the small diameter part of the mounting through hole 37, the end of the clamping adjusting screw 34 abuts against the clamping block 33. Then, by penetrating the mounting bolt 38 into the mounting screw hole 36 through the large diameter part of the mounting through hole 37, the clamping adjusting screw 34 and the clamping block 33 can be connected.

[0069] Moreover, the nut part of the mounting bolt 38 matches the large diameter part of the mounting through hole 37, so that the nut part of the mounting bolt 38 can be completely hidden into the mounting through hole 37, thereby not affecting the clamping of the clamping block 33 on the target object.

[0070] Since the connecting ring 35 can rotate in the mounting through hole 37, when the clamping adjusting screw 34 and the connecting ring 35 are rotated, the clamping block 33 is not affected by the rotation, i.e. does not rotate together. In this way, when the clamping block 33 has a specific shape, the clamping effect of the specific shape of the clamping block 33 is ensured.

[0071] As shown in Figure 4 - Figure 5 Specifically, in the present embodiment, the cross beam fixing mechanism 2 includes two sets of fixing assemblies for abutting against the inner walls of the vehicle on both sides of the cross beam 1, so as to fix the cross beam 1. The fixing assembly includes a connecting plate 21, a quick clamp 22 and an abutting block 23. The connecting plate 21 is connected with the cross beam 1, the quick clamp 22 is fixedly assembled on one side of the connecting plate 21 through a connecting screw 24, and the abutting block 23 is assembled at the end of the telescopic rod of the quick clamp 22.

[0072] The connecting plate 21 is used to connect with the crossbeam 1, serving as the basic support structure for the fixing components and ensuring that other components such as the quick clamp 22 and the abutment block 23 can be stably assembled and function. The quick clamp 22 is fixedly mounted on one side of the connecting plate 21 by the connecting screw 24. Its main function is to drive the abutment block 23 to abut against the inner wall of the vehicle through its telescopic rod, thereby fixing the crossbeam 1. The quick clamp 22 is an existing tool that can quickly and firmly clamp or fix workpieces. The principle of the quick clamp 22 is mainly based on the dead point principle of a mechanical four-bar linkage. It will not be described in detail here. The abutment block 23 is mounted at the end of the telescopic rod of the quick clamp 22 for direct contact with the inner wall of the vehicle.

[0073] In use, the handle of the quick-release clamp 22 is moved, causing the telescopic rod of the quick-release clamp 22 to push the abutment block 23 to move, so that the abutment block 23 is tightly abutted against the inner wall of the carriage. Furthermore, the self-locking effect of the quick-release clamp 22 ensures that the abutment block 23 remains tightly abutted against the inner wall of the carriage. When the fixing components on both sides of the crossbeam 1 are tightly abutted against the inner wall of the carriage, the crossbeam 1 is supported inside the carriage, thereby fixing the crossbeam 1.

[0074] When it is necessary to remove the crossbeam 1 from the carriage, the handle of the quick clamp 22 is moved, and the telescopic rod of the quick clamp 22 moves the abutment block 23 back to its initial position to unlock it. In this way, the crossbeam 1 can be quickly installed or removed simply by operating the quick clamp 22.

[0075] Furthermore, the abutment block 23 is provided with a reinforcing rib 27 on the side near the quick clamp 22.

[0076] By adding reinforcing ribs 27, the deformation resistance of the abutment block 23 under pressure can be improved, ensuring that the abutment block 23 can stably abut against the inner wall of the carriage, thereby maintaining the fixing effect of the crossbeam 1.

[0077] like Figure 3 As shown, further, the crossbeam 1 is provided with a plurality of first sliding grooves 11, and the opening of each first sliding groove 11 is semi-closed.

[0078] The beam fixing mechanism 2 can be slidably mounted on the beam 1 through the first sliding groove 11, so that the beam fixing mechanism 2 can change its position on the beam 1.

[0079] In this embodiment, the fixing assembly further comprises a fixing assembly slider 25 and a fixing screw 26. The fixing assembly slider 25 is fixedly assembled on the side of the connecting plate 21 away from the quick clamp 22. The side of the fixing assembly slider 25 away from the connecting plate 21 is slidingly assembled inside the first sliding groove 11, and the shape of the part of the fixing assembly slider 25 inside the first sliding groove 11 is the same as that of the first sliding groove 11. The fixing screw 26 is threaded through the connecting plate 21 and the fixing assembly slider 25 from the side of the connecting plate 21 away from the fixing assembly slider 25.

[0080] The sliding assembly of the fixing assembly slider 25 inside the first sliding groove 11 enables the position adjustment of the connecting plate 21 and the quick clamp 22 connected thereto along the beam 1.

[0081] The opening of the first sliding groove 11 is semi-closed, i.e., the internal space of the first sliding groove 11 is large, and the opening is small. This allows the fixing assembly slider 25, which has the same shape as the first sliding groove 11, to be prevented from falling out of the first sliding groove 11 when it is inside the first sliding groove 11, thereby playing a limiting role. The part of the fixing assembly slider 25 inside the first sliding groove 11, which has the same shape as the first sliding groove 11, can also sufficiently fill the first sliding groove 11, thereby ensuring the smoothness and stability of the sliding and preventing shaking during sliding or after being fixed.

[0082] The fixing screw 26 is threaded through the connecting plate 21 and the fixing assembly slider 25, so that the fixing screw 26 can be turned on the side of the connecting plate 21 away from the first sliding groove 11 and the side of the connecting plate 21 exposed to the outside for easy access. Turning the fixing screw 26 makes it threaded through the connecting plate 21 and the fixing assembly slider 25 and finally abut against the inner wall of the first sliding groove 11. The friction generated by the abutment of the fixing screw 26 and the inner wall of the first sliding groove 11 fixes the fixing assembly on the beam 1.

[0083] The provision of the fixing assembly slider 25 enables the position adjustment of the beam fixing mechanism 2 according to actual needs, thereby improving the flexibility and adaptability of the device. This sliding assembly mode simplifies the installation and disassembly process and improves the operation efficiency. The fastening effect of the fixing screw 26 ensures the stability of the beam fixing mechanism 2 and prevents loosening or displacement during use, thereby improving the safety and reliability of the entire device.

[0084] In this way, when the cross beam 1 is placed in a vehicle compartment of different sizes, the cross beam fixing mechanism 2 is slid in the first sliding groove 11 to move to a position close to the inner wall of the vehicle compartment for fixing. The accommodating device can be adapted to different types of vehicles of different sizes.

[0085] Specifically, when the cross beam 1 is installed on the vehicle compartment, the cross beam 1 is first placed horizontally on the vehicle compartment. Then, the two fixing assemblies of the cross beam fixing mechanism 2 are respectively slid to the vicinity of the two inner walls of the vehicle compartment. Then, the fixing screw 26 is rotated so that the fixing screw 26 abuts against the first sliding groove 11, so that the fixing assembly is fixed at the current position on the cross beam 1. Then, the cross beam 1 can be fixed to the vehicle compartment by operating the quick clamps 22 to push the abutting blocks 23 to abut against the inner wall of the vehicle compartment.

[0086] As shown in Figure 3 In this embodiment, a second sliding groove 12 is further formed in the cross beam 1, and a guide rail 13 is arranged in the second sliding groove 12.

[0087] The second sliding groove 12 is formed in the cross beam 1, and the guide rail 13 is arranged in the second sliding groove 12, so that the support mechanism 4 can slide on the cross beam 1 along the path of the guide rail 13.

[0088] As shown in Figure 6 - Figure 9 Specifically, the support mechanism 4 includes a support assembly for supporting and moving the target object fixing assembly 3. The support assembly includes a support frame 41, two pulleys 42, and two wheel shafts 43. The support frame 41 is located on one side of the cross beam 1 where the second sliding groove 12 is formed. The two wheel shafts 43 are arranged in the support frame 41, and the two pulleys 42 are rotatably arranged on the two wheel shafts 43, respectively, and are arranged on the guide rail 13.

[0089] The support frame 41 is in the shape of a V and wraps around the cross beam 1 and faces the second sliding groove 12. The pulleys 42 are rotatably arranged in the support frame 41 through the wheel shafts 43 and also contact the guide rail 13. That is, the pulleys 42 can rotate along the guide rail 13 to move the support frame 41. The support frame 41 is connected to the target object fixing assembly 3, so that when the support frame 41 moves, the target object fixing assembly 3 moves together, thereby achieving the effect of moving the target object fixing assembly 3 on the cross beam 1.

[0090] And the two pulleys 42 and two wheel shafts 43 are arranged, so that the support frame 41 has two fulcrums on the guide rail 13, which is more balanced and prevents the support frame 41 from shaking. Of course, more than two can also be arranged, depending on the specific situation and needs, which is not limited in this embodiment.

[0091] Compared with directly sliding in the second sliding groove 12, the pulley 42 is rotatably sleeved on the wheel shaft 43 and placed on the guide rail 13, which can effectively reduce the frictional resistance of the support mechanism 4 during movement, making movement easier. And improve the stability. The cooperation of the pulley 42 and the guide rail 13 ensures the stability of the support mechanism 4 during movement, avoiding safety hazards caused by shaking or deviation.

[0092] At the same time, because the pulley 42 is directly placed on the guide rail 13, it is convenient to install and disassemble. The installation and disassembly process of the vehicle object fixing device is more convenient.

[0093] As shown in Figure 3 Further, the guide rail 13 is arranged in a trapezoidal shape with a small outer diameter and a large inner diameter, and the shape of the pulley 42 matches the shape of the guide rail 13.

[0094] The design of the trapezoidal guide rail makes the pulley better fit the guide rail during movement, reducing instability caused by shaking or deviation and enhancing the stability of the entire device. The trapezoidal shape with a small outer diameter and a large inner diameter makes the pulley 42 easier to slide into the guide rail 13 during installation and maintain the correct position during use, simplifying the installation operation and avoiding the impact of improper installation or position deviation on the normal operation of the device. The complete matching of the shape of the pulley 42 and the guide rail 13, i.e. the pulley 42 is provided with a groove matching the shape of the guide rail 13, can reduce the friction of the pulley when sliding on the guide rail, thereby reducing wear and noise and prolonging the service life of the device.

[0095] Specifically, the support mechanism 4 further comprises a locking assembly for locking the support mechanism 4 when the target object fixing assembly 3 reaches a predetermined position. The locking assembly comprises a locking frame 44, a locking rod 45 and a locking block 46. The locking frame 44 is located on the side of the cross beam 1 away from the support assembly, and the locking frame 44 is fixedly connected with the support frame 41. The locking rod 45 slides through the locking frame 44, and one end of the locking rod 45 is located inside the first sliding groove 11. The locking block 46 is threadedly sleeved on one end of the locking rod 45 located in the first sliding groove 11, and the length of the locking block 46 is greater than the width of the first sliding groove 11.

[0096] The locking frame 44 is also in the shape of a V and can be connected and matched with the support frame 41, so that the locking frame 44 and the support frame 41 can completely wrap the cross beam 1. The locking block 46 is located inside the first sliding groove 11, the locking rod 45 penetrates through the locking frame 44 and the locking block 46, and the locking block 46 and the locking rod 45 are threadedly connected. In this way, when the locking rod 45 is rotated, the locking block 46 moves on the locking rod 45 when the locking block 46 cannot rotate with the locking rod 45.

[0097] When the length of the locking block 46 is greater than the width of the first sliding groove 11, the locking block 46 cannot rotate in the first sliding groove 11, thereby realizing the condition that the locking block 46 cannot rotate with the locking rod 45. In this way, when the locking rod 45 is rotated, the locking block 46 moves on the locking rod 45, and because the opening of the first sliding groove 11 is semi-closed, the opening of the first sliding groove 11 is smaller than the internal space, so the locking block 46 abuts against the groove wall at the opening of the first sliding groove 11, and the abutting force becomes greater with the rotation of the locking rod 45. Therefore, the locking block 46 and the cross beam 1 are fixed to each other, and the locking rod 45 also penetrates through the locking frame 44, so the locking frame 44 is also fixed. Therefore, the entire support mechanism 4 is fixed, and the target object fixing assembly 3 connected with the support mechanism 4 is also fixed. The support mechanism 4 can be quickly fixed after driving the target object fixing assembly 3 to the position corresponding to the target object to be clamped and fixed.

[0098] Further, the locking rod 45 is provided with a locking handle 47 at an end away from the first sliding groove 11.

[0099] The locking handle 47 can facilitate the rotation of the locking rod 45, so that the user can easily lock and unlock the support mechanism 4 and the target object fixing assembly 3, thereby reducing the operation difficulty and labor intensity.

[0100] It should be noted that each of the embodiments in the specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts between the embodiments can be referred to each other.
