[0051] This utility model discloses a control device to facilitate miniaturization and lightweight design. This utility model also provides a vehicle.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] like Figures 1-14 As shown, this embodiment of the present invention provides a control device, including a housing 100, a circuit board 200, and a cover connector 300. The housing 100 has a receiving cavity 130 and a first frame opening 120 communicating with the receiving cavity 130; the circuit board 200 can be placed into the receiving cavity 130 through the first frame opening 120; the cover connector 300 has a first connector 320 and a cover plate 310 disposed around the periphery of the first connector 320, the first connector 320 being electrically connected to the circuit board 200, and the cover plate 310 being able to close the first frame opening 120.

[0054] The control device provided in this embodiment of the utility model, since the first connector 320 is electrically connected to the circuit board 200 and located inside the housing 100, during the assembly process, the circuit board 200 enters the receiving cavity 130 through the first frame opening 120, and the cover plate 310 cooperates with the first frame opening 120 to close and complete the assembly operation. Since the cover plate 310 is arranged around the periphery of the first connector 320, the cover plate 310 and the first connector 320 are integrated into a single component. When the cover plate 310 is closed with the first frame opening 120 of the housing 100, the positioning of the first connector 320 relative to the housing 100 is achieved, and the electrical connection between the first connector 320 and the circuit board 200 ensures the transmission of electrical signals between the first connector 320 and the circuit board 200, thereby ensuring the realization of the control device function. By avoiding the separate setting of a cover plate structure and connector structure to close the first frame opening 120, the first connector 320 is used as part of the first frame opening 120, which improves the structural compactness between components and saves the amount of material used in the cover plate 310. This optimizes the lightweight design of the control device while facilitating its miniaturization.

[0055] Furthermore, it facilitates the assembly of the control device. In particular, with the circuit board 200 and cover connector 300 connected and structurally stable, the control device can be assembled simply by assembling the circuit board 200 and cover connector 300 relative to the housing 100, simplifying the assembly steps and saving time and effort.

[0056] The cover plate 310, serving as the outer contour cover, ensures a proper fit with the housing 100. A chamfered structure (such as a C-shaped chamfer) can be provided at the mating point between the housing 100 and the cover plate connector 300 (cover plate 310) to reduce assembly force. The cover plate 310 (and the housing 100) can be made of plastic, specifically PBT-GF30, to ensure injection molding strength and temperature resistance during the welding process between the first connector 320 and the cover plate 310.

[0057] The circuit board 200 can be a PCBA (Printed Circuit Board Assembly) or other types of circuit boards, without specific restrictions.

[0058] To facilitate wiring within the installation space, the control device also includes a second connector 210; the first connector 320 connects to the side of the circuit board 200 closest to the first frame opening 120, and the second connector 210 connects to the side of the circuit board 200 furthest from the first frame opening 120. Taking a sunshade controller used in a vehicle as an example, the first connector 320 and the second connector 210 can respectively serve as connectors for the motor end and the control end of the control device. The control end receives corresponding signals, which are then processed by the control device (including determining the working status of the sunshade, etc.). The motor end outputs corresponding signals to control the motor's operation and achieve the opening, closing, and position adjustment of the sunshade. Since the first connector 320 is connected to the side of the circuit board 200 near the first frame opening 120, and the second connector 210 is connected to the side of the circuit board 200 away from the first frame opening 120, the connection end and the control end of the control device are arranged opposite to each other at both ends of the control device. This facilitates reasonable wiring in limited spaces (such as inside a vehicle). Under the condition of coordinating the layout of the connection end and the control end, the length requirements at both ends of the control device can be effectively reduced to reduce the size requirements of the control device. This further facilitates the miniaturization design of the control device, reduces the space occupied by the control device, and makes the installation of the control device convenient.

[0059] In some embodiments, the control device further includes a first positioning structure, a second positioning structure, and a third positioning structure. The first positioning structure is used to position the circuit board 200 relative to the housing 100 along a first direction, the second positioning structure is used to position the circuit board 200 relative to the housing 100 along a second direction, and the third positioning structure is used to position the circuit board 200 relative to the housing 100 along a third direction; the first direction, the second direction, and the third direction are all different. By positioning the circuit board 200 with the first positioning structure, the second positioning structure, and the third positioning structure, the circuit board 200 can be positioned relative to the housing 100 in at least three different directions to achieve the positioning effect of the circuit board 200 within the receiving cavity 130.

[0060] Preferably, any two of the first, second, and third directions are perpendicular to each other. That is, the first and second directions are perpendicular to each other, the first and third directions are perpendicular to each other, and the second and third directions are perpendicular to each other. This makes the angle between any two of the first, second, and third directions 90° (allowing for machining error). Of course, the angle between any two of the first, second, and third directions can also be other angles, such as 30°, 45°, 60°, 120°, or 180°. The first direction can be the X direction, the second direction can be the Y direction, and the third direction can be the Z direction.

[0061] Specifically, the first positioning structure includes a first gap-eliminating rib 311, which is located on the side wall of the cover plate 310. When the cover plate 310 closes the first frame opening 120, the first gap-eliminating rib 311 abuts against the inner wall of the first frame opening 120. Because the first gap-eliminating rib 311 abuts against the inner wall (side) of the first frame opening 120, the cover plate 310 and the first frame opening 120 are fitted with a clearance. The clearance dimension between the cover plate 310 and the first frame opening 120 (e.g., ...) is... Figure 7 The first gap dimension a and the third gap dimension d are determined based on the height of the first gap-eliminating rib 311. Specifically, both sides of the cover plate 310 have first gap-eliminating ribs 311, and the height of the first gap-eliminating ribs 311 on both sides can be the same, preferably 0.15mm, so that the single-sided gap between the cover plate 310 and the first frame opening 120 is 0.15mm. Alternatively, the height of the first gap-eliminating ribs 311 on both sides of the cover plate 310 can be set to different or other dimensions to adjust the single-sided gap dimension between the cover plate 310 and the first frame opening 120. It is understood that the arrangement direction of the two sides of the cover plate 310 is the same as the first direction. The first gap dimension a and the third gap dimension d are preferably 0.15mm, but the dimensions of the first gap dimension a and the third gap dimension d can also be other values, such as 0.1mm or 0.2mm, etc. The specific dimensions are determined according to actual needs and are not specifically limited here.

[0062] The circuit board 200 is connected to the cover plate connector 300, which allows the circuit board 200 to be connected to the first connector 320 through a conductive element, and the cover plate 310 is connected to the first connector 320. Therefore, when the cover plate 310 closes the first frame opening 120, the circuit board 200 can be indirectly positioned with the housing 100 in the first direction through the cover plate 310.

[0063] To facilitate installation and reduce frictional loss between the circuit board 200 and the inner wall of the receiving cavity 130 during assembly, the sidewall of the circuit board 200 faces the first direction, and the sidewall of the circuit board 200 is clearance-fitted with the inner wall of the receiving cavity 130. For example... Figure 9 As shown, the fifth gap size f between the sidewall of the circuit board 200 and the inner wall of the receiving cavity 130 is 0.1 mm. Of course, the fifth gap size f can also be 0.15 mm or 0.2 mm, etc., and no specific limitation is made here, all of which are within the protection scope.

[0064] like Figure 8As shown, in the control device provided by this embodiment of the present invention, the second positioning structure includes an inner snap-fit ​​assembly disposed in the first frame opening 120 and a second gap-eliminating rib 133 disposed in the receiving cavity 130 and protruding towards the first frame opening 120. The inner snap-fit ​​assembly is used to abut against the outer surface of the cover plate 310; the second gap-eliminating rib 133 is used to abut against the side of the circuit board 200 facing away from the cover plate 310. Through the above arrangement, the cover plate 310 and the circuit board 200 are clamped between the inner snap-fit ​​assembly and the second gap-eliminating rib 133 to achieve positioning in the second direction ( Figure 8 Positioning in the horizontal direction. Dimensional chain analysis can be performed on the dimensions of the above components (such as the height of the second gap-eliminating rib 133 protruding from the inner wall of the receiving cavity 130) and the distance between the inner snap-fit ​​assembly and the second gap-eliminating rib 133 to confirm installation tolerances and ensure positioning effect.

[0065] To further improve the positioning effect, the inner snap-fit ​​assembly has at least one inner snap-fit, and the receiving cavity 130 has a limiting rib, which corresponds one-to-one with the inner snap-fit ​​and forms a groove for clamping the cover plate 310. For example... Figure 10 As shown, the inner snap-fit ​​assembly includes a first inner snap-fit ​​121 located at the bottom of the inner wall of the first frame opening 120 and a second inner snap-fit ​​122 located at the top of the inner wall of the first frame opening 120. The receiving cavity 130 has a first limiting rib 131 and a second limiting rib 132. The first inner snap-fit ​​121 corresponds one-to-one with the first limiting rib 131, forming a groove between them to clamp the cover plate 310. The second limiting rib 132 corresponds one-to-one with the second inner snap-fit ​​122, forming a groove between them to clamp the cover plate 310. This configuration further improves the positioning stability of the cover plate 310 in the second direction, reduces noise and other abnormal sounds generated when subjected to vibration, and thus improves the positioning effect of the circuit board 200 in the second direction.

[0066] like Figure 7 As shown, in some embodiments, the third positioning structure includes a third gap-eliminating rib 312, which is located on the top and / or bottom surface of the cover plate 310. The circuit board 200 is connected to the cover plate connector 300. When the cover plate 310 closes the first frame opening 120, the third gap-eliminating rib 312 abuts against the inner wall of the first frame opening 120. Specifically, the third gap-eliminating rib 312 is located on the top and / or bottom surface of the cover plate 310, and the top and / or bottom surface is adjacent to the side wall of the cover plate 310. Because the third gap-eliminating rib 312 abuts against the inner wall (top and / or bottom surface) of the first frame opening 120, the cover plate 310 and the first frame opening 120 are fitted with a clearance. The clearance size between the cover plate 310 and the first frame opening 120 (e.g., Figure 7The second gap dimension b and the fourth gap dimension e are determined based on the height of the third gap-eliminating rib 312. Specifically, the cover plate 310 may only have the third gap-eliminating rib 312 at the bottom, or it may have the third gap-eliminating rib 312 at the top of the cover plate 310. The height of the third gap-eliminating rib 312 at the bottom and top of the cover plate 310 may be the same, preferably 0.15 mm, so that the single-sided gap between the cover plate 310 and the first frame opening 120 is 0.15 mm. Alternatively, the height of the third gap-eliminating rib 312 at the bottom and top of the cover plate 310 may be set to different or other dimensions to adjust the single-sided gap dimension between the cover plate 310 and the first frame opening 120. It is understood that the arrangement direction of the bottom and top of the cover plate 310 is the same as the third direction. The second gap dimension b and the fourth gap dimension e are preferably 0.15 mm, but the dimensions of the second gap dimension b and the fourth gap dimension e may also be other values, such as 0.1 mm or 0.2 mm, etc. The specific dimensions are determined according to actual needs and are not specifically limited here.

[0067] like Figure 9 As shown, in some other embodiments, the third positioning structure includes: a support portion disposed within the receiving cavity 130, the support portion being used to support the first surface of the circuit board 200; and a crushing structure 134 disposed within the receiving cavity 130 and opposite to the support portion, the crushing structure 134 being used to mate with the second surface of the circuit board 200, the first surface and the second surface of the circuit board 200 being opposite to each other. The crushing structure 134 can be in contact with the second surface of the circuit board 200, in a clearance fit, or in a compression fit, etc. Taking a clearance fit as an example, there is a sixth gap size g between the crushing structure 134 and the second surface of the circuit board 200. The sixth gap size g is preferably 0.1 mm, but other sizes such as 0.15 mm or 0.2 mm can also be used; no specific limitation is made here, and all are within the scope of protection. The number of crushing structures 134 can be multiple. In this embodiment, there are two crushing structures 134 along the first direction ( Figure 9 Arranged horizontally in the middle.

[0068] like Figure 1 , Figure 5 and Figure 10 As shown, the top surface of the housing 100 is a concave-convex surface, with its central portion protruding beyond the two side portions. The concave-convex arrangement direction is a first direction, which is perpendicular to the assembly direction in which the circuit board 200 is placed within the receiving cavity 130. This design strengthens the top surface of the housing 100, thereby improving the strength of the first frame opening 120. Figure 6As shown, the first frame opening 120 has a structure similar to the Chinese character "pin" (品), with a relatively large middle space and relatively small spaces on both sides. On the basis of ensuring that the first connector 320 can be installed through the middle space, the cross-sectional size of the first frame opening 120 is further reduced. That is, it can not only ensure the arrangement of the first connector 320 and be relatively aesthetically pleasing, but also has the function of enhancing the strength of the first frame opening 120.

[0069] Furthermore, the top surface of the housing 100 has reinforcing ribs, and the extending direction of the reinforcing ribs is the first direction, and the first direction is perpendicular to the assembly direction of the circuit board 200 placed in the accommodation cavity 130. Through the above settings, the injection molding deformation of the first frame opening 120 is further reduced.

[0070] As Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the bottom surface of the housing 100 has an installation interface 110 for installation. The installation interface 110 can be a slot structure. One end of the installation interface 110 is a closed end 112, and the other end of the installation interface 110 is an open end 111. The open end 111 has an open slot 113, so that the installation structure of the part where the control device needs to be installed can enter the open slot 113 from the open end 111 and be limited by the closed end 112, realizing the assembly operation of the control device.

[0071] Taking the case where the control device needs to be installed in a vehicle as an example, the above-mentioned part where the control device needs to be installed can be an in-vehicle component, and the installation interface 110 serves as an interface for mechanical installation with the vehicle end.

[0072] The embodiment of the present utility model also provides a vehicle, including a sunshade and a control device for controlling the sunshade to block the window of the vehicle, and the control device is the control device as described in any one of the above.

[0073] Since the above control device has the above technical effects, the vehicle with the above control device should also have the same technical effects, which will not be elaborated here.

[0074] In this specification, each embodiment is described in a progressive manner. The key points of each embodiment are the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. <0000​The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
