Description

Technical Field

[0001] The present application belongs to the technical field of nut boxes, and in particular relates to a movable nut box and a car. Background Art

[0002] During the production and assembly of automobiles, it is usually necessary to install the functional mechanisms of the automobile (such as luggage racks, battery brackets, battery packs, seats, etc.) on the automobile body through nuts, and welding is also required when necessary. In the prior art, there are two types of nuts used for installation: fixed and movable. The position of fixed nuts cannot be adjusted, which will affect the assembly accuracy. In addition, due to reasons such as welding levels and tolerance accumulation, technicians usually choose nut boxes with flexible adjustable installation positions to reduce the difficulty of installation.

[0003] However, in actual applications, we have found that the existing nut boxes are not easy to assemble. For example, in some sliding nut boxes, the nuts protrude from the box body, resulting in a thicker thickness, occupying a larger installation space, and affecting the compactness of the assembly; in some sliding nut boxes, the nut cannot be locked in position after adjustment. After assembly is completed, the nut can still slide in the box body, affecting the stability of the assembly; at the same time, since the nut box needs to adapt to different installation spaces during assembly, multiple sizes of nut boxes need to be prepared during installation, which has a high manufacturing cost. Summary of the invention

[0028] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0029] Figure 1 It is a structural schematic diagram of a movable nut box in an embodiment of the present application. Figure 2 This is one of the partial structural exploded diagrams of a movable nut box in the embodiment of the present application; Figure 1As shown, the movable nut 300 box includes: a fixed seat 100, the fixed seat 100 is provided with a slide groove 110, and the middle of the slide groove 110 is provided with a first adjustment hole 111; a sliding member 200 is slidably connected with the slide groove 110, and the sliding member 200 is provided with a mounting groove; a nut 300 is fixed in the mounting groove, and the height of the nut 300 protruding from the movable plate does not exceed the height of the side wall of the slide groove 110; the nut 300 is arranged above the first adjustment hole 111; an adjustment component 400, including an expansion Box 410 and adjustment unit 420, the expansion box 410 is provided with an installation cavity, the fixing seat 100 is arranged in the expansion box 410, the adjustment unit 420 is arranged between the fixing seat 100 and the installation cavity, and the distance between the fixing seat 100 and the expansion box 410 is adjusted by the adjustment unit 420 to adjust the overall thickness of the nut 300 box; a fixing component is respectively connected to the fixing seat 100 and the expansion box 410, and the nut 300 box is fixed to different installation positions of the vehicle through the fixing component. By setting the nut 300 in the installation groove of the sliding member 200, and the protruding position of the nut 300 does not exceed the fixing seat 100, the overall structure is lighter and thinner, which is conducive to the assembly between connectors in a confined space; by setting the adjustment component 400, the thickness of the nut 300 box is adjusted, which can compensate for the assembly gap between connectors and reduce the assembly tolerance. It is suitable for working conditions where the nut 300 box needs to be used for auxiliary support and positioning, and the nut 300 box can be adapted to different installation environments. A first adjustment hole 111 is provided in the middle of the slide groove 110, which is convenient for screwing the bolt into the nut 300 to a greater depth, thereby improving the adaptability of the installation. The nut 300 box has a wide range of applications, low manufacturing cost, and is easy to promote.

[0030] In some embodiments, the first adjustment hole 111 is a long hole, and the first adjustment hole 111 is arranged on the sliding path of the nut 300. When the nut 300 slides to different positions to cooperate with the bolt, the end of the bolt can be screwed into the first adjustment hole 111 without abutting against the fixing seat 100 to avoid affecting the assembly.

Specifically, the adjusting slide plate 421 and the fixing seat 100 are connected by an inclined plane, which can change the direction of the force so that the force can be transmitted along the inclined plane. The accuracy of the thickness adjustment can be improved by adjusting the inclination of the inclined plane. At the same time, the inclined plane adjustment will not take up too much space, so that the nut 300 box as a whole remains light and thin; the labor-saving effect of the inclined plane adjustment is very significant; when the inclination angle of the inclined plane is smaller, the thrust-to-weight ratio is higher, the required thrust is smaller, and the adjustment using the adjusting rod 422 is also more labor-saving.

Specifically, by cooperating with the thread on the screw portion 4221 and the threaded hole, the thickness of the nut 300 box can be adjusted steplessly, the thickness of the entire nut 300 box can be adjusted, the assembly gap between the connectors can be compensated, and the assembly tolerance can be reduced. It is suitable for working conditions where the nut 300 box needs to be used for auxiliary support and positioning, and the applicability of the nut 300 box is also improved. In other embodiments, a plurality of snap-in sockets may be provided on the adjustment rod 422 , and a spring buckle may be provided at the opening of the expansion box 410 , which is connected with different snap-in sockets through the spring buckle to achieve graded adjustment of the adjustment slide 421 by the adjustment rod 422 .

[0034] In some embodiments, the adjustment box is provided with a second adjustment hole 411 corresponding to the first adjustment hole 111; and the adjustment slide 421 is provided with a third adjustment hole 4212. Specifically, the second adjustment hole 411 and the third adjustment hole 4212 are both long holes, the size of the second adjustment hole 411 is the same as the size of the first adjustment hole 111, and is located directly below the second adjustment hole 411; the third adjustment hole 4212 is located between the first adjustment hole 111 and the second adjustment hole 411, the length of the third adjustment hole 4212 is greater than the first adjustment hole 111, and it is necessary to ensure that when the adjustment slide 421 slides, the third adjustment hole 4212 is always located on the sliding path of the nut 300, so as to ensure that the adjustment slide 421 and the expansion box 410 will not affect the screwing depth of the bolt and the nut 300 when they cooperate.
