Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a trunk guide rail structure. Background Technology

[0002] Traditional car trunks typically feature a single, fixed flat surface with no independent internal partitions. Only some models are equipped with simple hooks for basic item placement with nets. As living standards improve, users increasingly demand more refined trunk space partitioning and measures to prevent items from sliding out. Current trunk partitions require pre-installed, fixed mounting bases, especially for vertical partitions, which are typically fixed to the trunk floor. However, these fixed bases cannot be moved, resulting in fixed and unadjustable partition proportions and limited flexibility. Adjusting the position of vertical partitions requires adding multiple mounting bases to the trunk floor, which is cumbersome and occupies additional space, reducing overall trunk capacity. Therefore, a flexible partition adjustment mechanism is urgently needed. Utility Model Content

[0003] This utility model aims to solve the technical problems existing in the prior art. In particular, it innovatively proposes a trunk guide rail structure, which can provide an installation carrier for the adjustable base of the trunk item partition and can adjust the position of the trunk item partition to reasonably divide the trunk space.

[0004] To achieve the above objectives, this utility model provides a trunk guide rail structure, including a pair of guide grooves extending forward and backward on the left and right sides of the trunk floor plate, respectively. The guide grooves are used for sliding the partition adjustment base of the trunk partition. A limit strip is provided in the guide groove corresponding to the retractable locking tongue at the bottom of the partition adjustment base. The limit strip is provided with locking teeth for the locking tongue to engage.

[0005] In the above scheme: the locking tongue is horizontally positioned, and flanges are provided on both sides of the guide groove opening. The limiting strip is located directly below one flange and is L-shaped. The horizontal portion of the L-shaped limiting strip is fixedly installed at the bottom of the guide groove, and the locking teeth are provided on the vertical portion of the limiting strip. Positioning it directly below the flanges avoids the area directly below the groove opening as much as possible, facilitating the insertion of the partition adjustment base.

[0006] In the above solution: a positioning stop is provided at the bottom of the guide groove for positioning the limiting strip, and a positioning groove is recessed on the bottom side of the flange directly above the limiting strip for the top of the limiting strip to engage. This facilitates the positioning of the limiting strip. After positioning by the positioning stop and the positioning groove, the limiting strip is then fixed in the guide groove by rivets, improving the installation efficiency of the limiting strip.

[0007] In the above solution: a guide strip is provided within the guide groove corresponding to the locking hook of the partition adjustment base. The contact surface between the guide strip and the locking hook is an arc surface that matches the bent part of the locking hook, allowing the locking hook to slide against the guide strip. This facilitates the sliding of the trunk partition adjustment base on the guide groove, and because the locking hook abuts against the guide strip, it is not easy for it to come off.

[0008] In the above solution: Both ends of the guide groove are provided with end caps, and the end caps are provided with guide and limiting structures for insertion into the guide groove; the end caps are also horizontally provided with claws located below the guide groove, the ends of the claws are provided with upward-facing barbs, and the bottom side of the guide groove is provided with anti-detachment grooves for the barbs to engage. The barbs can hook into the guide groove, physically preventing detachment.

[0009] In the above solution: the bottom side of the guide groove is provided with a receiving groove corresponding to the claw recess, so that the claw is flush with the bottom of the guide groove. The exterior is neat and aesthetically pleasing, and it is not easily disengaged due to collisions with other objects.

[0010] In the above scheme: the guide limiting structure includes a bottom limiting block inserted into the guide groove and side guide limiting blocks spaced apart on the left and right sides. The bottom limiting block is located between the two side guide limiting blocks, and the two side guide limiting blocks abut against the side walls of the guide groove respectively. The bottom of the bottom limiting block abuts against the bottom of the guide groove. A ring of ribs is provided on the outer side of each side guide limiting block. Setting the guide limiting structure as three independent elements—left, right, and bottom—provides a certain degree of flexibility and is reasonably designed. Furthermore, if one element deforms or breaks, the other two can be used to hold it in place, preventing it from falling out. The ribs increase friction, further preventing it from falling out.

[0011] The above solution also includes a trunk floor bracket installed at the bottom of the guide channel. The trunk floor bracket is used to support the trunk floor. One side of the trunk floor bracket is fixed to the bottom of the guide channel, and the other side of the trunk floor bracket is located outside the guide channel, forming a support platform for supporting the trunk floor. The top of the trunk floor bracket is provided with a slot for the side of the trunk floor to be inserted.

[0012] In the above solution: the slot is inclined towards the rear of the vehicle, so that the front end of the rear trunk floor can be inserted into the slot. This makes it easy to open the trunk floor from the rear of the car and directly insert the front end of the trunk floor into the trunk floor brackets on both sides. The design is reasonable.

[0013] In the above solution: the bottom of the guide groove is mounted on the vehicle body by guide rail mounting bolts spaced at the front and rear. The guide rail mounting bolts are equipped with pads, and the bottom of the guide groove is provided with a mounting groove for accommodating the pads, making the installation convenient and stable.

[0014] In summary, the beneficial effects of this utility model are as follows: the guide grooves guide the forward and backward movement of the partition adjustment base, thereby adjusting the position of the trunk partition; the limiting strip matches the locking tongue of the partition adjustment base, thereby locking the position of the partition adjustment base and ensuring the installation stability of the partition. A pair of guide grooves are located on both sides of the trunk floor bracket, avoiding the toolbox and facilitating access to items inside. Combined with the subsequently installed trunk floor bracket, the trunk floor can be placed and opened, resulting in a reasonable flow of movement and improved convenience.

[0026] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0027] like Figures 1-11As shown, a trunk guide rail structure includes a pair of guide rail assemblies located on the left and right sides of a trunk floor 5. Each guide rail assembly includes a guide groove 1 extending forward and backward and a trunk floor bracket 4 mounted at its bottom. The guide grooves 1 on both sides are used to restrict the trunk floor 5, and the trunk floor bracket 4 is used to support the trunk floor 5. Correspondingly, a clearance portion is provided on the vehicle body for mounting the guide grooves 1 and the trunk floor bracket 4. A toolbox is located below the trunk floor 5; therefore, the trunk floor 5 referred to in this utility model is also a toolbox cover.

[0028] A trunk floor bracket 4 is positioned at the joint of the front and rear trunk floor panels 5. One side of the trunk floor bracket 4 is fixed to the bottom of the guide groove 1, while the other side of the trunk floor bracket 4 is located outside the guide groove 1, forming a support platform 401 for supporting the trunk floor panels 5. The height of the support platform 401 is lower than the portion of the trunk floor bracket 4 fixed to the bottom of the guide groove 1, creating a step 403 between the two portions, which aligns the trunk floor panels 5.

[0029] The top of the trunk floor bracket 4 is provided with a slot 402 for the side of the trunk floor 5 to be inserted. The slot 402 is inclined towards the rear of the vehicle, so that the front end of the rear trunk floor 5 can be inserted into the slot 402. This makes it convenient to lift the trunk floor 5 from the rear of the car and directly insert the front end of the trunk floor 5 into the trunk floor brackets 4 on both sides. The design is reasonable.

[0030] The guide groove 1 has its opening facing upwards, and its bottom is mounted on the vehicle body via guide rail mounting bolts 104 spaced at both ends. The guide rail mounting bolts 104 are equipped with pads 105, and the bottom of the guide groove 1 has a mounting groove for accommodating the pads 105.

[0031] Both sides of the guide groove 1 are provided with flanges, and the guide groove 1 is used to guide the partition adjustment base 2. The top of the partition adjustment base 2 is provided with an insertion hole for inserting a vertical rear trunk partition, and the bottom of the partition adjustment base 2 is provided with locking hooks 201 and locking tongues 202 spaced apart on the left and right. The locking hooks 201 and locking tongues 202 extend downwards from the flanges on both sides, so that the partition adjustment base 2 can be locked in the guide groove 1.

[0032] Guide bars 101 and limiting bars 103 are provided below the flanges on both the left and right sides of the guide groove 1. The locking hook 201 is bent into a hook shape on the side away from the locking tongue 202. The contact surface between the guide bar 101 and the locking hook 201 is an arc surface that matches the bent part of the locking hook 201, so that the locking hook 201 can slide against the guide bar 101 and will not fall out during the back-and-forth movement of the partition adjustment base 2.

[0033] The limiting strip 103 is provided with locking teeth for the latch 202 of the horizontally positioned partition adjustment base 2 to engage. The latch 202 of the partition adjustment base 2 is telescopically oriented, and a button 203 is provided on the partition adjustment base 2 for retracting the latch 202. The limiting strip 103 is located directly below the flange on either side of the groove, allowing the bottom of the partition adjustment base 2 to extend into the guide groove 1. The partition adjustment base 2 is an externally purchased component and is a product applicable to this technical solution. The latch 202 and button 203 on the partition adjustment base 2 are conventional features on locks, intended to cooperate with the lower limiting strip 103, and are not innovative features of this technical solution.

[0034] The limiting strip 103 has an L-shaped cross-section. The horizontal portion of the L-shaped limiting strip 103 is fixedly installed at the bottom of the guide groove 1 by multiple spaced rivets 109. The vertical portion of the limiting strip 103 is located near the groove opening, and the retaining teeth are located at the top of the vertical portion of the limiting strip 103. A positioning stop 110 is provided at the bottom of the guide groove 1 for positioning the limiting strip 103. A positioning groove 111 is recessed on the bottom side of the flange directly above the limiting strip 103 for the top of the limiting strip 103 to engage, facilitating the positioning of the limiting strip 103. After positioning by the positioning stop 110 and the positioning groove 111, the limiting strip 103 is fixed in the guide groove 1 by the rivets 109, improving the installation efficiency of the limiting strip 103.

[0035] Both ends of the guide groove 1 are provided with end caps 102. The end of the end cap 102 that inserts into the guide groove 1 is provided with a bottom limiting block 109 and two side guide limiting blocks 108 spaced apart on the left and right. The bottom limiting block 109 and the two side guide limiting blocks 108 are all used to insert into the guide groove 1, with the bottom limiting block 109 located between the two side guide limiting blocks 108. The two side guide limiting blocks 108 are respectively used to engage between the limiting strip 103, the guide strip 101, and the side wall of the guide groove 1, and a ring of ridges is provided on the outer side of the side guide limiting blocks 108 to increase friction.

[0036] The bottom of the bottom limiting block 109 abuts against the bottom of the guide groove 1, and a claw 106 located outside the guide groove 1 is provided below the bottom limiting block 109. The end of the claw 106 is provided with an upward-facing barb, and the bottom side of the guide groove 1 is provided with an anti-disengagement groove 107 for the barb to engage. The bottom side of the guide groove 1 is recessed with a receiving groove corresponding to the claw 106, so that the claw 106 is flush with the bottom of the guide groove 1.
