The miniature model car has smaller parts and components, and has high requirement on assembly size precision. However, the overall size of the mini-car is too small, and the car body is fixed more inconveniently, so that the user can not assemble and disassemble the mini-car by himself. The invention provides a model car dismounting jig, when the model car is dismounted, a model car 1000 (a miniature model car, the same shall apply below without special description) of the model car 1000 can be fixed in the model car dismounting jig, so that the model car can be dismounted conveniently.

Fig. 1 is an exploded schematic view of a model car disassembly and assembly jig according to an embodiment of the present invention, fig. 2 is a schematic view of a structure of a model car disassembly and assembly jig according to an embodiment of the present invention, fig. 3 is a schematic view of a model car 1000 and a lower cover, fig. 4 is a schematic view of a model car 1000, an upper cover and a lower cover, and referring to fig. 1 to 4, the model car disassembly and assembly jig according to an embodiment of the present invention includes: an upper cover 100 and a lower cover 200.

The upper cover 100 includes a first body 110 and a first connecting portion 120, and the first connecting portion 120 is connected to a surface of the first body 110. The lower cover 200 includes a second body 210, a second connecting portion 220 and a supporting portion 290, the second connecting portion 220 is connected to the surface of the second body 210, the second body 210 has a maintenance hole 230 formed therethrough, the supporting portion 290 is disposed at both sides of the maintenance hole 230 to support the model car 1000, the model car 1000 can be exposed through the maintenance hole 230, and the first connecting portion 120 and the second connecting portion 220 are detachably connected to allow the model car 1000 to be clamped between the upper cover 100 and the lower cover 200.

Specifically, the second body portion 210 is provided with a through-hole 230, the size of the hole 230 is adapted to the size of the model car 1000, the model car 1000 is placed on the lower cover 200, and the bottom of the model car 1000 can be exposed through the hole 230 (as shown in fig. 3). When the model car 1000 is to be detached, the model car 1000 is fixed to the lower cover 200 to detach and attach parts of the front surface of the model car 1000, and after the front surface is detached, the upper cover 100 and the lower cover 200 are connected (as shown in fig. 2) to clamp the model car 1000 between the upper cover 100 and the lower cover 200. Turning over the model car dismouting tool, make model car 1000 invert (as shown in fig. 4), carry out dismouting through maintenance hole 230 to the spare part at the back of model car 1000, the whole dismouting process carries out centre gripping through model car dismouting tool to model car 1000 and fixes, prevents that model car 1000 from removing, and convenience of customers dismouting by oneself.

The supporting portion 290 may be a surface of the second body portion 210, and the mold is directly placed on the second body portion 210. The supporting portion 290 may also be a protrusion protruding from the surface of the second main body portion 210 to extend the depth of the maintenance hole 230, so as to prevent some structures on the model car 1000 from passing through the maintenance hole 230 and being supported on the workbench, thereby improving the versatility of the model car assembling and disassembling jig of this embodiment. It can be appreciated that the provision of the convex supporting portion 290 does not require an increase in the depth of the service hole 230 by increasing the thickness of the second body portion 210, to save manufacturing materials.

The upper cover 100 and the lower cover 200 are provided in a square configuration, which should not be construed as the only limitation of the present embodiment as long as the mold vehicle 1000 can be fixed.

It should be noted that the front and back of model car 1000 cannot be interpreted as the top and bottom of model car 1000, and the order of attaching and detaching model car 1000 differs depending on the structure of model car 1000. For example, some models 1000 require that the screws on the bottom of the chassis be removed first to remove the housing of the model 1000. Therefore, model car 1000 needs to be placed upside down on support 290, where the front of model car 1000 is interpreted as the bottom surface, not the top of model car 1000. That is, the front is merely interpreted as the model car 1000 facing the surface for the first time when disassembly is performed.

In addition, in some model cars 1000, the outer shell is easy to remove, the parts are mainly concentrated on the chassis, and the parts are arranged on the upper surface and the lower surface of the chassis, so that when the model car 1000 is disassembled, the outer shell can be removed firstly, and then the chassis is prevented from being arranged on the supporting part 290, so that the parts are removed. For whole car, the volume on chassis is littleer, consequently can reduce the overall dimension of model dismouting tool for the model car dismouting tool of this embodiment is littleer, conveniently carries.
