Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to an automobile seat crossbeam connecting plate assembly. Background Art

[0002] The automotive seat crossbeam connector is a specialized structure designed to enhance the stability and bending strength of the seat crossbeam. It is designed to improve the overall performance of the seat crossbeam, particularly in terms of side impact resistance. This structure incorporates a reinforcement between the seat crossbeam and the floor panel, thereby improving the overall bending resistance and side impact resistance of the seat crossbeam.

[0003] Conventional front seat crossbar connecting plates are typically welded to the vehicle frame floor. Due to this fixed joint structure, during actual production and assembly, the seat connection and crossbar hole locations occasionally experience misalignment, potentially due to manufacturing tolerances in the seat or crossbar. This not only impacts subsequent vehicle assembly, but forced assembly can also negatively impact the stability of the entire connection mechanism during subsequent use. Therefore, a new automotive seat crossbar connecting plate assembly is needed to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 4 The figure shows the entire structure of a car seat crossbeam connecting plate assembly of the utility model. Figure 1-Figure 4 In this embodiment, a car seat crossbeam connecting plate assembly includes a base plate 100 fixed to the frame floor, and first fixing ears 110 are provided on both sides of the top ends of the base plate 100. A top plate 200 is arranged above the base plate 100, and second fixing ears 210 are provided on both sides of the bottom ends of the top plate 200, corresponding to the first fixing ears 110. The first fixing ears 110 and the second fixing ears 210 are adjustable front-to-back, and third fixing ears 220 are provided at both ends of the top of the top plate 200. A crossbeam plate 300 is arranged above the top plate 200, and fourth fixing ears 310 are provided at both ends of the bottom of the crossbeam plate 300, corresponding to the third fixing ears 220. The third fixing ears 220 and the fourth fixing ears 310 are adjustable left-to-right.

[0022] In order to facilitate the initial positioning of the base plate 100, a positioning groove that fits in with the base plate 100 is provided on the frame floor. It can be understood that during the initial assembly, the base plate 100 can be directly placed in the positioning groove on the frame floor. The two can be connected by welding, bolts, etc. In this embodiment, welding is preferably used, and welding can provide a stable basic support for the connecting plate assembly.

[0023] The first fixing ear 110 also has a horizontal waist-shaped hole 1101, and the second fixing ear 210 has a circular hole 2101 corresponding to the waist-shaped hole 1101 in the center. A first bolt 400 is passed through and connected between the waist-shaped hole 1101 and the circular hole 2101. During installation, the second fixing ears 210 on both sides of the bottom of the top plate 200 can be directly clamped on the outside of the first fixing ear 110, and then the relative position of the top plate 200 can be slid back and forth according to the hole position of the seat connection part. After adjustment, the first bolt 400 is immediately screwed into the circular hole 2101 and the waist-shaped hole 1101, thereby realizing the installation and fixation between the first fixing ear 110 and the second fixing ear 210, and the top plate 200 and the base plate 100. Similarly, the third fixing lugs 220 further have horizontal waist-shaped holes 2201 near their ends, and the fourth fixing lugs 310 have circular holes 3101 at their ends corresponding to the waist-shaped holes 2201. Second bolts 500 are inserted and connected inside the waist-shaped holes 2201 and the circular holes 3101. During installation, the fourth fixing lugs 310 at both ends of the bottom of the crossbeam 300 are simply clamped inside the two third fixing lugs 220. The relative positions of the fourth fixing lugs 310 and crossbeam 300 are then slid left and right based on the hole locations. Once adjusted, the second bolts 500 are then screwed into the waist-shaped holes 2201 and the circular holes 3101, thereby securing the crossbeam 300 to the top plate 200. In summary, through the cooperation of the base plate 100, the first fixing ear 110, the top plate 200, the second fixing ear 210, the third fixing ear 220, the fourth fixing ear and the bolts, the car seat can be effectively prevented from being assembled and fixed due to the docking offset caused by the original manufacturing tolerance and the associated impact on the subsequent vehicle assembly, as well as the forced assembly that may have an adverse effect on the later use stability of the entire connection mechanism. It is also beneficial to later maintenance and replacement.

[0024] Furthermore, the interior of the crossbeam 300 is hollow, and the inner side of the hollow structure has multiple side-by-side reinforcement ribs 320 along the length of the crossbeam 300. Because the chair crossbeam supports the stability and bending strength of the chair crossbeam, the combination of the hollow structure and the reinforcement ribs 320 effectively ensures the mechanical strength and overall stability of the crossbeam 300.

[0025] Furthermore, the main sections of the base plate 100 and the top plate 200 are porous or hollow structures. By adopting the hollow design of the base plate 100 and the top plate 200, the weight of the entire beam-plate connecting plate assembly can be reduced, and the purpose of energy and material saving can also be achieved.

[0026] In summary, in the embodiment of the present invention, a car seat crossbeam connecting plate assembly is installed by clamping the second fixing ears 210 on both sides of the bottom of the top plate 200 on the outside of the first fixing ears 110, and then sliding the relative position of the top plate 200 back and forth according to the hole position of the seat connection part. After adjustment, the first bolt 400 is screwed into the round hole 1 2101 and the waist-shaped hole 1 101, thereby achieving the installation and fixation between the first fixing ear 110 and the second fixing ear 210, and the top plate 200 and the base plate 100. The fourth fixing ears 310 at both ends of the bottom of the crossbeam plate 300 are clamped on the inner sides of the two third fixing ears 220, and then sliding the relative positions of the fourth fixing ears 310 and the crossbeam plate 300 left and right according to the hole position. After adjustment, the second bolt 500 is screwed into the waist-shaped hole 2201 and the round hole 2 3101, thereby achieving the installation and fixation between the crossbeam plate 300 and the top plate 200. It can effectively prevent docking deviation caused by original manufacturing tolerances and the subsequent impact on vehicle assembly.

[0027] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
