DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following further elaborates on the present invention in detail with reference to the accompanying drawings.
[0024] Embodiment:
[0025] Refer to Figure 1 - Figure 5, a vehicle engine compartment frame disclosed by the present utility model includes a first wooden board 1 and a second wooden board 2. Positioning holes 3 are provided at both ends of the first wooden board 1. Second wooden boards 2 are arranged on both sides of the first wooden board 1. On the side of the second wooden board 2 close to the first wooden board 1, a clamping block 4 and a fixing block 5 are respectively arranged from top to bottom. A jack 6 communicating with the positioning hole 3 is provided at the top of the clamping block 4. A fixing assembly 7 for fixing the first wooden board 1 is arranged in the fixing block 5.
[0026] In this embodiment, when installing the front engine compartment frame, the end of the first wooden board 1 is inserted between the clamping block 4 and the fixing block 5 of the second wooden board 2. As the first wooden board 1 is inserted, the positioning hole 3 at the end of the first wooden board 1 will gradually engage with the jack 6 of the clamping block 4 and the fixing assembly 7 of the fixing block 5. When the axes of the fixing assembly 7, the jack 6, and the positioning hole 3 coincide, a slender columnar object is inserted into the jack 6 and the positioning hole 3 until it contacts the fixing assembly 7, and then the fixing assembly 7 is pressed once, which can activate the fixing assembly 7 and make the fixing assembly 7 pop into the positioning hole 3 and the jack 6, achieving the effect of fixing the first wooden board 1, making the assembly of the front engine compartment frame simpler and improving the installation efficiency of the front engine compartment frame.
[0027] When disassembling, a slender columnar object is also used to press the fixing assembly 7, and the fixing assembly 7 is pressed into the fixing block 5, so that the fixing assembly 7 can be separated from the first wooden board 1 without continuous pressing, effectively reducing the disassembly difficulty of the front engine compartment frame, thereby improving the disassembly efficiency of the front engine compartment frame and facilitating the maintenance and repair of the front engine compartment frame.
[0028] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, the fixing assembly 7 is composed of a positioning pin 71, a support spring, and a limiting unit 72. A spring groove 8 is provided at the top of the fixing block 5. A positioning pin 71 for penetrating the first wooden board 1 is slidably connected in the spring groove 8. An avoidance groove 9 is provided at the bottom of the positioning pin 71, and a support spring is arranged between the positioning pin 71 and the spring groove 8. A limiting unit 72 is arranged between the outer side wall of the positioning pin 71 and the spring groove 8.
[0029] In this embodiment, by providing a spring groove 8 in the fixing block 5 and connecting a positioning pin 71 in the spring groove 8 through a support spring, the elastic force of the support spring can be used to push the positioning pin 71 out of the spring groove 8 for inserting the positioning pin 71 into the positioning hole of the first wooden board 1 and the jack 6 of the clamping block 4, thereby quickly connecting the first wooden board 1 and the second wooden board 2.
[0030] However, due to the setting of the support spring, during the process of pressing the positioning pin 71 into the spring groove 8, as long as the pressure on the positioning pin 71 is removed, the positioning pin 71 will be pushed back by the support spring, resulting in increased difficulty in disassembling the first wooden board 1 and the second wooden board 2. Therefore, a limiting unit 72 is provided between the positioning pin 71 and the spring groove 8, such as Figure 3 As shown, after the positioning pin 71 is pressed into the spring groove 8, the limiting unit 72 will hold the positioning pin 71 in the spring groove 8. Then, by pressing the positioning pin 71 again, the positioning pin 71 can be released to re-extend from the spring groove 8, making the use of the fixing assembly 7 simpler and easier to operate, and improving the installation and disassembly efficiency of the front engine compartment frame.
[0031] In a further preferred embodiment of the present invention, as Figure 3 shown, the limiting unit 72 includes a track groove 721, a connecting rod 722, and a roller 723. A track groove 721 is formed on the outer sidewall of the positioning pin 71, and a roller 723 is rotatably arranged in the track groove 721. One side of the roller 723 away from the positioning pin 71 is connected to the inner sidewall of the spring groove 8 through a connecting rod 722.
[0032] In this embodiment, by processing a track groove 721 on the outer sidewall of the positioning pin 71 and using the connecting rod 722 installed on the inner wall of the spring groove 8 to limit the movement range of the track groove 721, the effect of restricting the ejection of the positioning pin 71 can be achieved, so that when disassembling the front engine compartment frame, it is not necessary to continuously apply pressure to the positioning pin 71, making the separation of the first wooden board 1 and the second wooden board 2 simpler.
[0033] However, due to the setting of the connecting rod 722, friction will occur between the connecting rod 722 and the track groove 721 when the positioning pin 71 moves along the axis of the spring groove 8, resulting in damage to the connecting rod 722 and the track groove 721. Moreover, the resistance generated during friction is relatively large, which will increase the resistance of the positioning pin 71 to bounce and reset, affecting the efficiency of the positioning pin 71 to fix the first wooden board 1. Therefore, a roller 723 is connected to the connecting rod 722. By contacting the inner wall of the track groove 721 with the roller 723, the sliding friction is changed into rolling friction, which can effectively reduce the friction damage and the resistance when the positioning pin 71 moves, and make the use effect of the limiting unit 72 better.
[0034] In a further preferred embodiment of the present invention, as Figure 5 shown, two sets of track grooves 721 are provided and connected end to end in sequence. Each set of track grooves 721 is composed of a long uphill section 7211, a long downhill section 7212, a short uphill section 7213, and a short downhill section 7214. The long uphill section 7211, the short downhill section 7214, the short uphill section 7213, and the long downhill section 7212 are connected end to end in sequence and form a plurality of intersecting corners at the connection points.
[0035] In this embodiment, since the positioning pin 71 has two states of popping out and retracting, and the movement state of the positioning pin 71 is controlled by the support spring and the limiting unit 72, the positioning pin 71 can have different forms at different positions in the track groove 721 by changing the shape of the track groove 721 in the limiting unit 72.
[0036] As Figure 5 shown, the track groove 721 is composed of a long uphill section 7211, a long downhill section 7212, a short uphill section 7213, and a short downhill section 7214, and the long uphill section 7211, the short downhill section 7214, the short uphill section 7213, and the long downhill section 7212 are connected end to end in sequence, so that the highest point of the track groove 721 forms a trough, which can be used to hold the roller 723, thereby using the roller 723 to limit the upward movement of the positioning pin 71, making the positioning pin 71 retract in the spring groove 8, facilitating the separation of the first wooden board 1 from the second wooden board 2.
[0037] By arranging two sets of track grooves 721 on the outer side wall of the positioning pin 71, the two sets of track grooves 721 are connected end to end, and a set of rollers 723 and connecting rods 722 are arranged in each set of track grooves 721, the force on the positioning pin 71 can be made uniform when it moves, so that the movement of the positioning pin 71 is more stable, and the roller 723 holds the positioning pin 71 when it moves to the bottom end of the track groove 721, so that the positioning pin 71 will not come out of the spring groove 8 when it extends out of the spring groove 8 to fix the first wooden board 1, which is used to ensure the use stability of the fixing component 7.
[0038] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5 shown, the head end of each corner is concavely formed with a concave surface, so that the concave surface and the corresponding tail end form a stepped surface 10.
[0039] In this embodiment, since the track groove 721 is provided with a long uphill section 7211, a long downhill section 7212, a short uphill section 7213, and a short downhill section 7214, and the long uphill section 7211, the long downhill section 7212, the short uphill section 7213, and the short downhill section 7214 are connected in sequence in the manner as Figure 5 shown, the roller 723 can continuously move along the track groove 721.
[0040] When the roller 723 moves to the corner of the long uphill section 7211 and the short downhill section 7214, as the pressure on the positioning pin 71 is removed, the positioning pin 71 will move upward under the push of the support spring, so that the roller 723 moves downward relative to the positioning pin 71. At this time, the center of the roller 723 at the corner is located on the left side of the lower edge of the long uphill section 7211 and the short downhill section 7214, which will cause the roller 723 to be tractionally reset by the inclined plane of the long uphill section 7211 when moving downward, resulting in the positioning pin 71 not being stably pressed into the spring groove 8, affecting the running stability of the limiting unit 72.
[0041] Therefore, by observing Figure 4 it can be found that a concave surface is provided at the head of the short uphill section 7213 at the corner, so that there is a stepped surface 10 between the head of the short uphill section 7213 and the tail of the short downhill section 7214. Then, by observing Figure 5 it can be found that stepped surfaces 10 for check prevention are provided at the head and tail of each corner, which can prevent the roller 723 from being reset when moving to the corner, so as to ensure that the roller 723 can only move forward, thereby making the limiting effect of the track groove 721 more stable.
[0042] In a further preferred embodiment of the present invention, as Figure 3 shown, a gap is left between the end of the connecting rod 722 close to the roller 723 and the roller 723, and a compression spring is arranged in the gap.
[0043] In this embodiment, by leaving a gap between the roller 723 and the connecting rod 722 and arranging a compression spring in the gap, a force away from the connecting rod 722 can be applied to the roller 723 by the compression spring, so that the roller 723 jumps off the step under the push of the compression spring when moving to the corner of the track groove 721, thereby ensuring that the roller 723 cannot be reset when moving to the corner, and further ensuring the running stability of the limiting unit 72.
[0044] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
