Description
Technical field
The utility model relates to a kind of control appliance of electric automobiles, specifically, relates to a kind of casing of electric vehicle controller.
Background technology
At present, electric motor car comprises electric bicycle, electro-tricycle, battery-operated motor cycle etc., controller is as the control maincenter part of electric motor car, need have well shockproof, heat dispersion, otherwise be easy to cause the work of electric motor car undesired and even operate malfunctioningly, its radiating effect of existing controller is bad, the heat radiation degree that mainly is power tube is not enough, do not have excellent contact between power tube and the radiator, the fin transition is inhomogeneous, can not reach the requirement of heat radiation etc.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of install firm, shockproof effect is good and the casing of electric vehicle controller of power tube good heat dissipation.
The technical scheme that realizes above-mentioned purpose is: a kind of casing of electric vehicle controller, comprise loam cake, shell block and wiring board, described wiring board is embedded in the shell block, its improvement is: the inner chamber of described shell block has the groove seat near on the side perisporium of bottom, in the wiring board one end insertion groove seat, engage by buckle between described loam cake and the shell block, cover on described and have card article, snap in the power tube on the wiring board between the inner chamber opposite side of card article and shell block, has first raised line on the card article, the inner chamber opposite side of shell block has second raised line, and described power tube is spacing by first raised line and second raised line.
Described first raised line is a wedge shape, and lozenges contacts with power tube.
Described buckle comprises the circular protrusions that has on C shape ring that loam cake has and the shell block, when loam cake engages with shell block, during the C shape that the circular protrusions on the shell block snaps in loam cake is encircled.
Two lateral walls of described shell block have radiating ribs.
Cover on described and have radiating ribs.
The beneficial effects of the utility model: engage by bayonet socket between loam cake and the shell block, need not screw, operation easily, install firm, power tube is spacing by first raised line and second raised line, shockproof effect is good, raised line is spacing to power tube, make power tube well to contact with shell block with loam cake, the heat that power tube work produces just can be as soon as possible by leaving on loam cake and the shell block, and the power tube thermal diffusivity is good, and raised line is a wedge shape, more increase the contact area of power tube and loam cake, helped heat radiation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further detailed description.
As shown in Figure 1, a kind of casing of electric vehicle controller, comprise loam cake 1, shell block 2 and wiring board 3, described wiring board 3 is embedded in the shell block 2, the inner chamber of described shell block 2 has groove seat 2-1 near on the side perisporium of bottom, in the wiring board 3 one end insertion groove seat 2-1, engage by buckle 1-2 between described loam cake 1 and the shell block 2, has card article 1-1 on the described loam cake 1, snap in the power tube 3-1 on the wiring board 3 between the inner chamber opposite side of card article 1-1 and shell block 2, have the first raised line 1-1-1 on the card article 1-1, the inner chamber opposite side of shell block 2 has the second raised line 2-2, described power tube 3-1 is spacing by the first raised line 1-1-1 and the second raised line 2-2, installs firm and has improved shockproof effect.
As shown in Figure 1, the described first raised line 1-1-1 is a wedge shape, and lozenges contacts with power tube 3-1.The first raised line 1-1-1 has radiating ribs near the site distribution of loam cake 1, and power tube 3-1 contacts with lozenges, and meaning has also increased area of dissipation, and like this, power tube 3-1 rapid heat dissipation is that radiating effect is all right.
As shown in Figure 1, described buckle 1-2 comprises that the C shape that loam cake 1 has is encircled the circular protrusions 2-3 that has on 1-2-1 and the shell block 2, and when loam cake 1 engaged with shell block 2, the circular protrusions 2-3 on the shell block 2 snapped among the C shape ring 1-2-1 of loam cake 1.Buckle is closely tight.The good airproof performance of shell block 2.
As shown in Figure 1, two lateral walls of described shell block 2 have radiating ribs.Strengthened radiating effect.
As shown in Figure 1, have radiating ribs on the described loam cake 1, strengthened radiating effect.The periphery of same described shell block 2 is a C shape groove near the both sides of bottom.
Installation process of the present utility model is, wiring board 3 is snapped in the groove seat 2-1 on the inner chamber one side perisporium of shell block 2, power tube 3-1 is leaned against on the inner chamber opposite side perisporium of shell block 2, with loam cake 1 one sides elder generation and shell block 2 buckles, power tube 3-1 is contacted with the lozenges of the first raised line 1-1-1, again loam cake 1 opposite side is fastened by bayonet socket 1-2 and shell block 2 fully.Casing of electric vehicle controller of the present utility model have install firm, shockproof effect is good and the advantage of power tube good heat dissipation.
