Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to a vehicle toolbox. Background Technology

[0002] A car spare tire toolbox is a container specifically designed for storing automotive repair tools. It's typically placed in the spare tire well or elsewhere in the trunk. A spare tire toolbox can hold essential driving tools such as an air pump, tire repair tools, a tow rope, and battery cables, making them convenient for drivers to use while driving. When a tire goes flat, the tire repair tools and air pump can be used to repair and inflate it. When the vehicle needs to be towed, the tow rope can be used. These tools can help drivers save themselves in emergencies and avoid being stuck due to a lack of tools.

[0003] However, when existing automotive toolboxes are placed in the trunk, their connection to the spare tire often relies on a single fixing method (such as bolting the toolbox to secure the spare tire). This single fixing structure has significant shortcomings: firstly, it is difficult to create a stable limiting effect, causing relative wobbling between the toolbox and the spare tire; secondly, during vehicle operation, this wobbling can further cause direct collisions between the spare tire cover and the spare tire, and between the spare tire and the toolbox, ultimately producing continuous abnormal noises and affecting the driving experience. Utility Model Content

[0004] This utility model provides a vehicle toolbox to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a vehicle toolbox, comprising a circular toolbox body, a tool groove inside the toolbox body, and a frustum-shaped structure on the outside of the toolbox body; a mounting hole is provided at the center of the toolbox body, and a fixing locking mechanism is provided on the mounting hole; a plurality of connecting holes are provided on the outside of the mounting hole, and a fixing snap-fit ​​mechanism is provided in each connecting hole.

[0006] Furthermore, the fixing and locking mechanism includes a mounting cylinder, a protective round washer, a fixing threaded rod, and a rotary switch disc. The top of the mounting cylinder is provided with five plug-in plates, which are horizontally and equally spaced on the top of the mounting cylinder. The mounting cylinder is fixedly connected to the mounting hole through the five plug-in plates. The rotary switch disc is fixedly disposed on the top of the fixing threaded rod. The protective round washer is sleeved on the fixing threaded rod and is located between the rotary switch disc and the upper surface of the toolbox body. The mounting cylinder is provided with a through hole, through which the fixing threaded rod extends to the bottom of the toolbox body.

[0007] Furthermore, each of the fixed locking mechanisms includes a wing nut, a fixing rod, and a locking element. The wing nut is rotatably connected in the tool groove and located on the connecting hole. The fixing rod is divided into a threaded section and a smooth section from top to bottom. The threaded section is threadedly connected to the wing nut. The locking element is disposed inside the fixing rod. Two movable holes are provided at the smooth section.

[0008] Furthermore, the snap-fit ​​component includes a movable block, a snap-fit ​​threaded rod, a knob, and two snap-fit ​​rods. The movable block is slidably connected to the inside of the fixed rod. The bottom of the snap-fit ​​threaded rod is rotatably connected to the top of the movable block. The rod body of the snap-fit ​​threaded rod is threadedly engaged with the internal threaded hole at the top of the fixed rod, and its top extends beyond the top of the fixed rod and is fixedly connected to the knob. The two snap-fit ​​rods are symmetrically slidably connected in the two movable holes. Each snap-fit ​​rod has a notch with an inclined block on the notch. The side wall of the movable block has an inclined groove that slides with the inclined block.

[0009] Furthermore, there are several connection holes, specifically five connection holes, which correspond to the five hub holes on the spare tire's hub.

[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0011] Firstly, this utility model uses five horizontally spaced plug-in plates at the top of the mounting cylinder to form a stable connection with the mounting hole in the middle of the toolbox body, ensuring that the mounting cylinder does not shift on the toolbox. The fixing threaded rod extends through the through hole on the mounting cylinder to the bottom of the toolbox body. When it is necessary to fix the toolbox and the spare tire, rotating the rotary switch disc at the top can drive the fixing threaded rod downward into the center fixing hole of the spare tire hub and the pre-set screw hole in the vehicle trunk, realizing the longitudinal locking of the toolbox and the spare tire. The protective round washer sleeved on the fixing threaded rod can fill the gap between the fixing threaded rod and the mounting cylinder during the locking process and buffer the pressure during locking, avoiding damage to the components caused by hard contact.

[0012] Solving the problem of longitudinal swaying when fixed in a single location: Compared with the simple fixation of a single bolt in the traditional system, this mechanism uses a double longitudinal fixation of "plug plate positioning + threaded rod locking" to firmly lock the toolbox to the spare tire, which greatly reduces the longitudinal relative displacement between the toolbox and the spare tire during vehicle operation and fundamentally reduces the probability of abnormal noise caused by longitudinal collision.

[0013] Enhanced stability and durability: The protective round pad not only buffers locking pressure but also reduces frictional wear between the fixed threaded rod and the mounting cylinder, extending the service life of the mechanism; the five equally spaced plug plates ensure that the mounting cylinder is subjected to uniform force, preventing loosening of the installation due to excessive local force.

[0014] Secondly, the toolbox body and spare tire in this utility model are fixed in a way that allows the toolbox to be tightly engaged with the spare tire hub in the horizontal direction. This, combined with the longitudinal locking mechanism, forms a "double fixation" that completely eliminates lateral relative sway between the toolbox and the spare tire, preventing abnormal noise caused by lateral collisions. The extension length of the fixing rod can be adjusted by rotating the wing nut, and the extension range of the locking rod can be controlled by rotating the knob. This allows the mechanism to adapt to spare tire hubs with different bore diameters and thicknesses, improving the versatility of the toolbox. It eliminates the need to design a separate fixing structure for different vehicle models, reducing production and adaptation costs. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The following detailed description, in conjunction with the accompanying drawings, illustrates the technical solution of a vehicle toolbox provided by various embodiments of this utility model.

[0027] Reference Figures 1 to 7 As shown, this utility model embodiment provides a vehicle toolbox, including a circular toolbox body 1. The toolbox body 1 has a tool groove 10 inside, which can be customized according to the shape of commonly used repair tools such as air pumps and tire repair tools, so as to accurately limit the tools in the groove and prevent the tools from shaking inside the toolbox. The exterior of the toolbox body 1 has a frustum structure. The design of the vehicle toolbox body 1 as a circle with a frustum structure on the outside makes it more compatible with the spare tire compartment and spare tire hub of the car. The toolbox body 1 has a mounting hole 11 at the center, and a fixing locking mechanism 2 is provided on the mounting hole 11. Several connecting holes 12 are provided on the outside of the mounting hole 11, and a fixing snap-fit ​​mechanism 3 is provided in each connecting hole 12.

[0028] Specifically, the fixing and locking mechanism 2 includes a mounting cylinder 21, a protective round pad 22, a fixing threaded rod 23, and a rotary switch disc 24. The top of the mounting cylinder 21 is provided with five plug-in plates 211, which are horizontally and equally spaced on the top of the mounting cylinder 21. The mounting cylinder 21 is fixedly connected to the mounting hole 11 through the five plug-in plates 211. The rotary switch disc 24 is fixedly disposed on the top of the fixing threaded rod 23. The protective round pad 22 is sleeved on the fixing threaded rod 23 and is located between the rotary switch disc 24 and the upper surface of the toolbox body 1. The mounting cylinder 21 is provided with a through hole, and the fixing threaded rod 23 extends through the through hole to the bottom of the toolbox body 1.

[0029] The five horizontally spaced plug-in plates 211 on the top of the mounting cylinder 21 form a stable connection with the mounting hole 11 in the middle of the toolbox body 1, ensuring that the mounting cylinder 21 does not shift on the toolbox. The fixing threaded rod 23 extends through the through hole on the mounting cylinder 21 to the bottom of the toolbox body 1. When it is necessary to fix the toolbox and the spare tire, rotating the rotary switch disc 24 on the top can drive the fixing threaded rod 23 to be screwed down into the center fixing hole of the spare tire hub and the pre-set screw hole in the vehicle trunk, thereby achieving longitudinal locking of the toolbox and the spare tire. The protective round pad 22 sleeved on the fixing threaded rod 23 can fill the gap between the fixing threaded rod 23 and the mounting cylinder 21 during the locking process and buffer the pressure during locking to avoid damage to the components caused by hard contact.

[0030] Solving the problem of longitudinal swaying in single fixation: Compared with the simple fixation of a single bolt in traditional systems, this mechanism uses a double longitudinal fixation of "plug plate 211 positioning + threaded rod locking" to firmly lock the toolbox to the spare tire, greatly reducing the longitudinal relative displacement between the toolbox and the spare tire during vehicle operation, and fundamentally reducing the probability of abnormal noise caused by longitudinal collision.

[0031] Improved stability and durability: The protective round pad 22 not only buffers the locking pressure, but also reduces frictional wear between the fixed threaded rod 23 and the mounting cylinder 21, extending the service life of the mechanism; the five equally spaced plug plates 211 ensure that the mounting cylinder 21 is subjected to uniform force, avoiding loosening of the installation due to excessive local force.

[0032] Specifically, each of the fixed locking mechanisms 3 includes a wing nut 31, a fixing rod 32, and a locking member 33. The wing nut 31 is rotatably connected in the tool groove 10 and located on the connecting hole 12. The fixing rod 32 is divided into a threaded section 321 and a smooth section 322 from top to bottom. The threaded section 321 is threadedly connected to the wing nut 31. The locking member 33 is disposed in the fixing rod 32. Two moving holes 323 are provided at the smooth section 322.

[0033] Specifically, the snap-fit ​​component 33 includes a movable block 331, a snap-fit ​​threaded rod 332, a knob 333, and two snap-fit ​​rods 334. The movable block 331 is slidably connected to the inside of the fixed rod 32. The bottom of the snap-fit ​​threaded rod 332 is rotatably connected to the top of the movable block 331. The rod body of the snap-fit ​​threaded rod 332 is threadedly engaged with the internal threaded hole at the top of the fixed rod 32, and its top extends beyond the top of the fixed rod 32 and is fixedly connected to the knob 333. The two snap-fit ​​rods 334 are symmetrically slidably connected in the two movable holes 323. Each snap-fit ​​rod 334 is provided with a notch 335. The notch 335 is provided with a wedge 336. The side wall of the movable block 331 is provided with a groove 337 that slidably engages with the wedge 336.

[0034] When fixing the toolbox body 1 and the spare tire, first align the five connecting holes 12 on the toolbox with the five hub holes on the spare tire hub. Then, rotate the wing nut 31 to move the fixing rod 32 downward along the connecting hole 12, and move the bare rod section 322 on the fixing rod 32 through the hub hole on the hub to below the hub hole.

[0035] Then, rotate the knob 333 on the top of the snap-fit ​​threaded rod 332 to drive the moving block 331 to slide up and down inside the fixed rod 32. The inclined groove 337 on the side wall of the moving block 331 and the inclined block 336 on the notch 335 of the snap-fit ​​rod 334 form a sliding fit. When the moving block 331 slides upward, the inclined groove 337 will generate a lateral thrust on the inclined block 336, pushing the two symmetrical snap-fit ​​rods 334 to extend outward along the moving hole 323 of the smooth rod section 322. After the two snap-fit ​​rods 334 are extended outward, the two snap-fit ​​rods 334 are located on the outside of the smooth rod section 322.

[0036] Rotating the wing nut 31 again moves the fixing rod 32 upward along the connecting hole 12, moving the snap-fit ​​rod 334 to the bottom of the wheel hub hole, thus fixing the toolbox body 1 and the spare tire. This allows the toolbox to be tightly snapped into the spare tire wheel hub in the horizontal direction, forming a "double fixation" with the longitudinal locking mechanism 2, completely eliminating the lateral relative sway between the toolbox and the spare tire and preventing abnormal noise caused by lateral collisions. The extension length of the fixing rod 32 can be adjusted by rotating the wing nut 31, and the extension range of the snap-fit ​​rod 334 can be controlled by rotating the knob 333. This allows the mechanism to adapt to spare tire wheel hubs with different hole diameters and thicknesses, improving the versatility of the toolbox and eliminating the need to design a separate fixing structure for different vehicle models, thus reducing production and adaptation costs.

[0037] If disassembly is required, rotate the knob 333 in the opposite direction to make the moving block 331 slide downward, the thrust of the inclined groove 337 on the inclined block 336 will disappear, the locking rod 334 will retract, and then rotate the wing nut 31 upward to remove the fixing rod 32.

[0038] Specifically, there are five connection holes 12, which correspond to the five hub holes on the spare tire's hub.

[0039] The five connections correspond one-to-one with the five hub holes on the spare tire hub. Each connection hole 12 is equipped with a fixing snap-fit ​​mechanism 3, forming a "five-point lateral fixing" layout. When all the fixing snap-fit ​​mechanisms 3 work simultaneously, the five snap-fit ​​points can apply a uniform lateral fixing force to the toolbox from different directions on the spare tire hub, making the toolbox and the spare tire hub a whole, avoiding the problem of uneven force caused by single-point or few-point fixing. Achieving all-round limiting and completely eliminating abnormal noise: The five-point lateral fixing, combined with the longitudinal locking of the fixing locking mechanism 2, forms a three-dimensional fixing system of "longitudinal and lateral + multi-point", completely covering all possible directions of shaking between the toolbox and the spare tire, avoiding collisions between the spare tire cover and the spare tire, and between the spare tire and the toolbox during vehicle operation, solving the problem of continuous abnormal noise from the root and improving the driving experience.
