Description

Technical Field

[0001] The utility model relates to the technical field of vehicle compartment reinforcement, in particular to a device for reinforcing a commercial truck vehicle compartment. Background Art

[0002] To ensure superior mechanical strength and wear resistance, modern commercial truck cabins often use a "well"-shaped rectangular frame as the skeleton structure of the entire cabin. The entire skeleton structure is divided into six large blocks, namely the six faces of a rectangular parallelepiped. These six large frames are then welded together to form a complete cabin skeleton. To increase the strength and rigidity of the entire cabin, special reinforcement devices are often installed at the connection between each longitudinal beam and cross beam of the skeleton. However, the reinforcement devices of existing cabin processing manufacturers generally have problems such as poor shear resistance and low stability.

[0003] For example, a Chinese utility model patent with the publication number CN209043619U discloses a truck test cargo box reinforcement device. The connection between the longitudinal beam and the cross beam in this solution is fixed only by a longitudinal and cross beam connecting plate composed of two steel sheets in the solution. The longitudinal and cross beam connecting plates of this structure obviously have problems such as poor shear resistance and low stability. Based on this, a device for strengthening the cargo box of a commercial truck is proposed. Utility Model Content

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figure 1-Figure 5 , a device for strengthening a commercial truck compartment of this embodiment includes a longitudinal beam 16, two wedge plates 1 and a second support plate 5 located on one side thereof, one side of the two wedge plates 1 is respectively fixedly connected with a first rear support ear 3, the lower sides of the two wedge plates 1 are respectively fixedly connected with a first lower stabilizing plate 13, a first support plate 2 is clamped between the two first rear support ears 3, a second support plate strengthening mechanism is provided on one side of the first support plate 2 to provide support for the second support plate 5, a longitudinal beam limiting mechanism for fixing the longitudinal beam 16 is provided above the first rear support ear 3, a longitudinal beam strengthening mechanism for providing support for the longitudinal beam 16 is provided on one side of the wedge plate 1, a wedge plate shearing mechanism for improving the shear resistance of the wedge plate 1 is provided on the upper side of the wedge plate 1, the second support plate strengthening mechanism includes two second front support ears 12 fixedly connected to one side of the first support plate 2, the upper sides of the two second front support ears 12 They are respectively fixedly connected with second side support ears 4 which abut against the upper sides of the first rear support ears 3. The longitudinal beam limiting mechanism includes a second support plate 5 arranged on the upper sides of the two second side support ears 4. The upper side of the second support plate 5 is fixedly connected with two third limiting plates 7 for fixing the longitudinal beam 16 from both sides. The longitudinal beam strengthening mechanism includes a first upper support ear 10 fixedly connected to the upper sides of the two wedge-shaped plates 1. The third limiting plate 7 and the first upper support ear 10 abut against a second upper support ear 11 fixedly connected to the upper side of the first support plate 2. The wedge plate shearing mechanism includes an inclined connecting plate 8 fixedly connected to the upper sides of the two wedge plates 1. Reinforcing ribs 9 are provided on the inclined connecting plate 8. The first limiting hole 6 is provided on the third limiting plate 7, the first upper support ear 10 and the second upper support ear 11. A second limiting hole 14 is provided on the second support plate 5, and a third limiting hole 15 is provided on the first support plate 2.

[0026] All materials of the reinforced structure are made of high-strength metal of special material. When multiple such reinforcement devices are set on the crossbeam 17, the longitudinal beam 16 can be bolted through the third limit plate 7. The intersection of the reinforced crossbeam 17 and the longitudinal beam 16 can significantly improve the shear resistance of the crossbeam 17, so that the gravity of the cargo borne by the longitudinal beam 16 is evenly distributed to the crossbeam 17, thereby improving the overall stability of the car. At least 3 crossbeams 17 can be installed at the bottom of the car. The more crossbeams 17 are installed, the higher the reinforcement performance.

[0027] The implementation principle of a commercial truck compartment reinforcement device in the embodiment of the present application is as follows: the first lower stabilizing plate 13 is placed on the upper surface of the crossbeam 17, and the longitudinal beam 16 is placed on the upper surface of the second support plate 5. At this time, the gravity of the longitudinal beam 16 can be divided into two force directions according to the vectorial nature of the force. In the first decomposed direction, the second support plate 5 applies pressure to the second side support ear 4, and then the second side support ear 4 is further decomposed to apply pressure to the first rear support ear 3 and the second front support ear 12 respectively, and the force of the second front support ear 12 is transmitted to the lower end of the first support plate 2. , that is, it acts on the crossbeam 17. Similarly, the first rear support ear 3 also acts on the crossbeam 17 through the first lower stabilizing plate. The second decomposition direction is transmitted by the iron pin set in the first limiting hole 6. The gravity of the longitudinal beam 16 is transmitted to the second upper support ear 11 and the first upper support ear 10 through the third limiting plate 7 and the iron pin. The first upper support ear 10 then transmits the force to the two wedge plates 1, and the wedge plate 1 transmits it to the crossbeam 17. Similarly, the force on the second upper support ear 11 is transmitted to the first support plate 2, and then transmitted to the crossbeam 17 through the first support plate 2.

[0028] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
