Description

TECHNICAL FIELD

[0001] The utility model relates to a indicating lamp device of oral digital impression instrument. BACKGROUND

[0002] In the process of establishing a three-dimensional tooth mold image, an operator usually performs optical scanning on the upper and lower jaw regions in the patient's oral cavity in a handheld oral digital impression instrument mode, and then performs image recognition and synthesis through a rear-end host computer to display a corresponding three-dimensional tooth mold image on a screen for subsequent preparation of dental implantation or false tooth production.

[0003] The oral digital impression instrument needs to indicate the working state of the device during use. Currently, the industry mainly uses LED status lights to indicate the working state of the device to guide the operator to switch different work flows. In the indicating light of the oral digital impression instrument, the position, size, color uniformity, power consumption, heat consumption, state adjustability, and appearance texture of the indicating light are all important indicators.

[0004] In the existing design of the indicating light of the oral digital impression instrument, the LED light ring is the best LED light status indication scheme for users. The advantages of this scheme are that it is convenient for users to observe from various angles. The traditional LED light ring uses multiple LED groups to realize a ring-shaped light belt. This scheme realizes the LED light ring through a large number of LED light groups. The main problem of this scheme is that if a small number of LED lights are used, color non-uniformity will occur. To ensure the appearance texture, a large number of LED lights need to be added. However, increasing the number of LED lights will cause the space size to be large, which in turn causes the size of the oral digital impression instrument to be too large, affecting the device holding experience. Moreover, the setting constraints, power consumption, and heat consumption increase. INVENTION CONTENTS

[0005] The utility model is made to solve the above technical problems, and aims to provide an indicating light device of an oral digital impression instrument, which is space-saving, efficient, energy-saving, high in uniformity, and state-adjustable.

[0006] One embodiment of the utility model relates to an indicating light device of an oral digital impression instrument, which is arranged between a scanning head and a body of the oral digital impression instrument. The indicating light device comprises at least one light inlet portion, which is arranged correspondingly to a light emitting element arranged in the interior of the body and receives light emitted from the light emitting element; a light outlet portion, which is formed in a ring shape and exposed between the scanning head and the body; and a light guide portion, which is arranged in a manner of extending from the light inlet portion to the light outlet portion. The end edge of the light inlet portion side of the light guide portion is formed in a shape of being closer to the light outlet portion in the axial direction as the position in the circumferential direction is farther away from each light inlet portion.

[0007] According to the indicating lamp device, by arranging less light emitting elements, power consumption and energy consumption can be reduced, and the device is not restricted in size, and the size of the digital dental impression instrument will not be increased. In addition, the end edge of the light guide part on the light entry part side is formed in an arc shape, and the position on the axis direction is closer to the light exit part as the position on the circumferential direction is farther away from the light entry part. By the light guide part with such a structure, the light received from the light entry part can be homogenized and guided to the light exit part.

[0008] Preferably, the light entry part is opposite to the light emitting element with a uniform gap.

[0009] According to the indicating lamp device, the light can enter the light guide part within a certain angle range, and the light from the light emitting element can be better received, and the light receiving efficiency and the uniformity of the light exit part can be improved.

[0010] In addition, the light exit part is a lamp ring indicating part, which is arranged outwardly protruding from the light guide part, and the outer periphery of the lamp ring indicating part is consistent with the outer periphery of the scanning head and the body.

[0011] According to the indicating lamp device, by arranging the lamp ring indicating part, the operator can easily observe the lamp ring indicating part from any angle.

[0012] Preferably, the indicating lamp device further comprises a mounting and positioning part for mounting and positioning the scanning head fixing seat of the digital dental impression instrument, and the mounting and positioning part comprises a mounting part formed by extending from the inner surface of the light exit part towards the scanning head, for mounting the scanning head fixing seat outside; and at least one positioning part, which is a recess formed by recessing from the upper surface of the mounting part, for engaging the circumferential positioning part of the scanning head fixing seat.

[0013] According to the indicating lamp device, the mounting and positioning part for mounting and positioning the scanning head fixing seat comprises the mounting part and the at least one recess as the positioning part. The mounting part is mounted with the scanning head fixing seat outside, and the at least one recess as the positioning part engages the circumferential positioning part, such as a convex part, of the scanning head fixing seat, to achieve the mounting and positioning of the scanning head fixing seat. The structure of the digital dental impression instrument can be simplified, and the miniaturization of the digital dental impression instrument can be further achieved.

[0014] As another way of the installation and positioning part for installing and positioning the scanning head fixing seat of the digital dental impression device, the installation and positioning part comprises: an installation part formed by extending from the inner surface of the light emitting part towards the scanning head, for externally sleeving the scanning head fixing seat; and at least one positioning part, which is a protruding part formed by protruding from the upper surface of the installation part, for engaging with the circumferential positioning part of the scanning head fixing seat.

[0015] Similarly, the indicator light device is also used for installing and positioning the scanning head fixing seat, comprising an installation part and at least one protruding part as a positioning part, which engages with the circumferential positioning part, such as a recess, of the scanning head fixing seat. Therefore, the structure of the digital dental impression device can also be simplified, and the miniaturization of the digital dental impression device is further realized.

[0016] Preferably, two light emitting elements are provided, and two light inlet parts are respectively arranged corresponding to the two light emitting elements, and each light inlet part is opposite to each light emitting element through a uniform gap.

[0017] In the present application, two light emitting elements are used, which can reduce power consumption and heat consumption compared with the previous case of using multiple LED groups to realize the ring-shaped light belt.

[0018] In addition, the two light inlet parts are arranged at positions symmetrical to the axis of the machine body inside the machine body.

[0019] According to the indicator light device of the structure, by arranging the two light inlet parts at positions symmetrical to the axis of the machine body inside the machine body, the uniformity of light emission can be fundamentally ensured.

[0020] Preferably, a rounded corner is arranged on the upper surface and the lower surface of the lamp ring indicating part facing the scanning head and the machine body.

[0021] By arranging a rounded corner on the upper surface and the lower surface of the lamp ring indicating part facing the scanning head and the machine body, good installation of the indicator light device, the scanning head and the machine body can be realized, and the appearance gap difference problem can be reduced.

[0022] In addition, the indicator light device is a transparent structure body integrally formed by molding.

In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0048] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] First, refer to Figure 1 and Figure 2 The general structure of the oral digital impression instrument using the indicator lamp device of the present application is described.

[0050] Figure 1 is a perspective view of an oral digital impression instrument using an indicator lamp device of the present application. Figure 2 is a perspective exploded view of an oral digital impression instrument using an indicator lamp device of the present application.

[0051] As Figure 1 and Figure 2As shown, the oral digital impression apparatus as the main structure includes a scanning head 21, a scanning head fixing seat 22, a machine body 23 and an indicator light device 11. The scanning head 21 is connected with the machine body 23 through the scanning head fixing seat 22 and the indicator light device 11, thereby forming an integrated structure. When using the oral digital impression apparatus, the operator holds the machine body 23 to send the scanning head 21 into the oral cavity of the patient, thereby performing optical scanning on the upper and lower jaw regions of the patient. A not-shown mirror and the like are arranged in the inside of the scanning head 21, and a not-shown power supply device, an optical element, a processor and the like are arranged in the inside of the machine body 23. In addition, optical channels and gas channels are formed in the inside of the scanning head 21 and the machine body 23.

[0052] The indicator light device 11 of the utility model is clamped between the scanning head 21 and the machine body 23. The specific structure of the indicator light device 11 is described with reference to Figure 5 、 Figure 6 、 Figure 7 in addition, in the embodiment, the case of setting two LED lamps is taken as an example for description.

[0053] The indicator light device 11 mainly includes a light inlet part 11A, a lamp ring indicating part 11B, a mounting positioning part 11C and a light guide part 11D. In the embodiment, the indicator light device 11 is a transparent structure body integrally formed by molding, which is an integral molding piece of plastic PC material as an example.

[0054] The light inlet part 11A is formed in a shape corresponding to the outer shape of the LED lamp 12 as a light emitting element, and in the state that the indicator light device 11 is installed, the light inlet part 11A is opposite to the LED lamp 12 with a uniform gap in a manner of surrounding the LED lamp 12 from the outside.

[0055] The LED lamp 12 is a single-color LED lamp or a multi-color LED lamp, and the color, brightness and working state can be changed by adjusting the current and frequency of each independent interface. The mounting mode of the LED lamp 12 is described with reference to Figure 8 In the embodiment, the case of setting two LED lamps 12 is taken as an example for description. Since the power supply device, optical element, processor and the like are arranged in the inside of the machine body 23, the space inside is very limited. The two LED lamps 12 are arranged as much as possible at positions symmetrical to the axis of the machine body 23 in the inside of the machine body 23, and the positions of the two LED lamps 12 in the axial direction can be slightly staggered, then the two LED lamps 12 are connected with the button S through the connecting part 13, and further electrically connected with the not-shown power supply device through the bus L. In this way, the space in the inside of the machine body 23 can be reasonably used, and the size of the machine body will not be increased for setting the LED lamp.

[0056] Since two LED lights 12 are arranged in positions inside the body 23 which are symmetrical with respect to the axis of the body 23, two light-incident portions 11A are arranged respectively corresponding to the two LED lights 12. The two light-incident portions 11A are arranged uniformly in the circumferential direction.

[0057] The light ring indicating portion 11B is configured as a light-emitting portion. After the light emitted by the LED light 12 enters the light-incident portion 11A, the light enters the light ring indicating portion 11B via the light guide portion 11D. The light ring indicating portion 11B is exposed between the scanning head 21 and the body 23, and the operator can easily observe the light ring indicating portion 11B from any angle. The light ring indicating portion 11B is formed in a ring shape and is arranged in a manner protruding outward from the light guide portion 11D. The outer periphery of the light ring indicating portion 11B coincides with the outer periphery of the scanning head 21 and the body 23. In addition, as shown in the figure, a round corner R is arranged on the upper surface and the lower surface of the light ring indicating portion 11B which face the scanning head 21 and the body 23. By arranging the round corner R, good installation of the indicating light device 11, the scanning head 21 and the body 23 can be achieved, and the problem of appearance gap difference can be reduced. Figure 6

[0058] The mounting and positioning portion 11C protrudes further in the direction of the scanning head 21 from the upper surface of the light ring indicating portion 11B which faces the scanning head 21, and includes a mounting portion 11C1 and at least one positioning portion 11C2 (four in this example). The mounting portion 11C1 is formed in a manner extending further in the direction of the scanning head 21 from the inner surface of the light ring indicating portion 11B, and the scanning head fixing seat 22 is mounted on the mounting portion 11C1 in a manner of being externally sleeved. The positioning portion 11C2 is a recess formed in a manner recessed from the upper surface of the mounting portion 11C1. The positioning portion 11C2 is engaged by a protrusion which is not shown and serves as a circumferential positioning portion of the scanning head fixing seat 22, and limits the circumferential position of the scanning head fixing seat 22.

[0059] The light guide portion 11D is arranged in a manner extending from the light-incident portion 11A to the light ring indicating portion 11B. The light guide portion 11D is formed in a ring shape which surrounds the inside of the body 23 as a whole. The lower end edge of the light guide portion 11D is formed in a shape such as a substantially arc shape, in which the position in the axial direction is closer to the light ring indicating portion 11B as the position in the circumferential direction is further away from the light-incident portion 11A. By being arranged in this way, the light received by the light-incident portion 11A from the LED light 12 can be uniformly transmitted to the light ring indicating portion 11B and diffused outward from the light ring indicating portion 11B.

[0060] When the oral digital impression apparatus is started, the LED light 12 emits multi-color LED light beams. These light beams enter the light guide portion 11D via the light-incident portion 11A, are homogenized by the light guide portion 11D, and are guided to the light ring indicating portion 11B.

[0061] According to the indicating light device with the above structure, the following technical effects are achieved: ​

[0062] 1) The LED lamps are arranged in the settable part inside the body, which can reduce power consumption and energy consumption, and the arrangement is not restricted, and the size of the digital dental impression instrument will not be increased. In addition, fewer LED lamps can also save the IO port of the control chip. Each LED lamp can be independently adjusted to form a variety of LED states, and the left and right independent adjustment can adapt to various space structure occasions.

[0063] 2) The light guide part can uniformly guide the light of the LED lamp received from the light receiving part to the lamp ring indicating part, and diverge from the lamp ring indicating part to the outside.

[0064] 3) The lamp ring indicating part is formed in a ring shape and is exposed between the scanning head and the body, so that the operator can easily observe the lamp ring indicating part from any angle.

[0065] The above describes the embodiments of the present application and their variants, but it should be understood that the present disclosure is not limited to the above embodiments and structures. The present disclosure also includes various variants and equivalent variants. In addition, various combinations, methods, and further combinations of only one element, more than one element, or less than one element are also within the scope and idea of the present disclosure.

[0066] For example, in the above embodiment, two LED lamps are arranged as an example, but the present application is not limited thereto, and one LED lamp or more than three LED lamps can also be arranged. In the case of arranging one LED lamp, one light receiving surface is arranged correspondingly, and in the case of arranging three LED lamps, three light receiving surfaces are arranged correspondingly. Regardless of the number of LED lamps, the light guide part is arranged to uniformly guide the light of the LED lamp received from the light receiving part to the lamp ring indicating part.

[0067] In addition, it is more ideal to coat the inner surface of the lamp ring indicating part with a reflective material to increase the brightness of the light emitted from the lamp ring indicating part.

[0068] In the above embodiment, the indicating lamp device includes the light receiving part 11A, the lamp ring indicating part 11B, the mounting positioning part 11C, and the light guide part 11D. However, the mounting positioning part 11C can be omitted. That is, the scanning head fixing seat 22 is not positioned through the indicating lamp device.

[0069] Further, in the above-described embodiment, the positioning portion 11C2 is exemplified as a recessed portion formed in a manner of being recessed from the upper surface of the mounting portion 11C1. The positioning portion 11C2 is engaged with a non-illustrated convex portion of the scan head fixing seat 22 as a circumferential positioning portion, and limits the circumferential position of the scan head fixing seat 22. The present application is not limited thereto, and can be formed as a positioning portion 11C2 that is a protruding portion formed in a manner of protruding from the upper surface of the mounting portion 11C1. The positioning portion 11C2 is engaged with a non-illustrated recessed portion of the scan head fixing seat 22 as a circumferential positioning portion, and limits the circumferential position of the scan head fixing seat 22.
