[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] Please also read Figures 1 to 7The accessory identification device 10 provided in the embodiment of the present application is now described. The accessory identification device 10 comprises: a main body shell 11 and an accessory main body 12.
[0034] The main body shell 11 is provided with at least two sensing elements 111, and at least two sensing elements 111 are arranged at intervals in the same direction; the accessory body 12 can be rotatably installed on the main body shell 11, and the accessory body 12 is provided with at least one annular triggering member 121, and the annular triggering member 121 is used to trigger the sensing elements 111 at different positions to identify different types of accessory bodies 12. By providing at least two sensing elements 111 on the main body shell 11 and providing at least one annular triggering member on the accessory body, the sensing elements 111 at different positions can be triggered by changing the position of the annular triggering member to identify different types of accessory bodies; due to the provision of the annular triggering member, the accessory body rotatably installed on the main body shell 11 can also keep triggering the sensing elements 111; the accessory identification device 10 can be used in conjunction with the rotatably installed accessory, thereby improving the versatility of the accessory identification device 10.
[0035] Specifically, the at least two sensing elements 111 have at least two installation methods.
[0036] The first installation method is that at least two sensing elements 111 are installed on the main shell 11 from the inside to the outside with a distance therebetween; at least two sensing elements 111 are installed on the main shell 11 from the inside to the outside; the accessory body 12 has at least two, and each accessory body 12 is installed with an annular triggering member 121 of different diameters or different quantities; when the annular triggering members 121 of different diameters and / or different quantities trigger the sensing elements 111 at different positions and / or different quantities, the types of different accessory bodies 12 can be identified.
[0037] It should be noted that the at least two sensing elements 111 mentioned in the present application are installed in the main body shell 11 at intervals from the inside to the outside; in fact, the sensing elements are arranged in sequence at intervals in a direction gradually away from the starting point with the center of the main body shell 11 as the starting point, so as to achieve the installation method in which the at least two sensing elements 111 are installed in the main body shell 11 at intervals from the inside to the outside.
[0038] Exemplarily, when there are two accessory bodies, the two accessory bodies are defined as a first accessory body and a second accessory body; a first annular trigger 1211 is set on the first accessory body, and a second annular trigger 1212 is set on the second accessory body, and the diameter of the second annular trigger 1212 is greater than the diameter of the first annular trigger 1211. According to the setting of each annular trigger of the accessory body, a first sensing element 1111 and a second sensing element 1112 are installed on the main body shell 11 from the inside to the outside. When the first accessory body is installed on the main body shell 11, the first annular trigger 1211 can trigger the first sensing element 1111 to obtain the type information of the first accessory body; when the second accessory body is installed on the main body shell 11, the second annular trigger 1212 can trigger the second sensing element 1112 to obtain the type information of the second accessory body. Therefore, it is only necessary to change the diameter of the annular trigger to obtain the type information of the accessory body by triggering the sensing elements 111 at different positions.
[0039] It is understandable that when there is a third accessory body in the accessory body, the first annular trigger 1211 and the second annular trigger 1212 are simultaneously provided on the third accessory body; when the third accessory body is installed on the main body shell 11, the first annular trigger 1211 and the second annular trigger 1212 can be used to trigger the first sensing element 1111 and the second sensing element 1112 to obtain the type information of the third accessory body. In other words, when multiple sensing elements are provided, the type information of the corresponding accessory body can be identified by only changing the size of the annular trigger; or the type information of the corresponding accessory body can be identified by a combination of changing the size of the annular trigger and changing the number of the annular triggers.
[0040] The second installation method is that at least two sensing elements 111 are installed on the main shell 11 from top to bottom; the accessory body 12 has at least two, and each accessory body 12 is installed with annular trigger parts of different heights and / or different numbers; when the annular trigger parts 121 of different heights and / or different numbers trigger the sensing elements 111 of different positions and / or different numbers, the types of different accessory bodies 12 can be identified.
[0041] Exemplarily, when there are two accessory bodies, the two accessory bodies 12 are defined as a first accessory body and a second accessory body; a first annular trigger 1211 is set on the first accessory body, and a second annular trigger 1212 is set on the second accessory body, and the first annular trigger 1211 and the second annular trigger 1212 are installed at a vertical interval. According to the setting of each annular trigger of the accessory body, a first sensing element 1111 and a second sensing element 1112 are installed from top to bottom on the main body shell 11. When the first accessory body is installed on the main body shell 11, the first annular trigger 1211 can trigger the first sensing element 1111 to obtain the type information of the first accessory body; when the second accessory body is installed on the main body shell 11, the second annular trigger 1212 can trigger the second sensing element 1112 to obtain the type information of the second accessory body. Therefore, by changing the position of the annular trigger in the height direction, the sensing elements at different positions can be triggered by the annular triggers at different heights to obtain the type information of the accessory body.
[0042] It is understandable that when there is a third accessory body in the accessory body, the first annular trigger 1211 and the second annular trigger 1212 are simultaneously provided on the third accessory body; when the third accessory body is installed on the main body shell 11, the first annular trigger 1211 and the second annular trigger 1212 can be used to trigger the first sensing element 1111 and the second sensing element 1112 to obtain the type information of the third accessory body. In other words, when multiple sensing elements are provided, the type information of the corresponding accessory body can be identified by only changing the position of the annular trigger in the height direction; the type information of the corresponding accessory body can also be identified by a combination of changing the position of the annular trigger in the height direction and changing the number of annular triggers.
[0043] Specifically, by setting a certain number of sensing elements, different numbers of annular triggering parts can be set in conjunction with the sensing elements to trigger sensing elements at different positions to obtain type information of different accessory bodies. Figure 7 shown.
[0044] In more detail, the sensing element is installed in the above two ways, because both of them adopt an annular trigger member; with such a structure, when the accessory body is installed in the main body shell 11, no matter whether the accessory body is fixedly installed or rotatably installed, as long as the accessory body is installed in place, even if the accessory body rotates, the annular trigger member always keeps triggering the sensing element.
[0045] The main body shell 11 is provided with a first assembly part 1101, and the accessory body 12 is provided with a second assembly part 1201. The cross sections of the first assembly part 1101 and the second assembly part 1201 are both circular. The first assembly part 1101 is provided with a first magnetic attraction component 1102, and the second assembly part 1201 is provided with a second magnetic attraction component 1202. When the accessory body 12 is rotatably mounted on the main body shell 11, the first magnetic attraction component 1102 and the second magnetic attraction component 1202 are oppositely attracted. With such a structure, when the accessory body 12 is installed, the installation of the accessory body 12 can be completed only by the opposite attraction of the first magnetic attraction component 1102 and the second magnetic attraction component 1202, and the accessory body 12 can also rotate relative to the main body shell 11.
[0046] A first inner cylinder 114 is provided at the bottom of the first bracket 112, and a first rotation limiting notch 115 is provided in the first inner cylinder 114; a first rotation limiting convex portion 122 is provided at the top center of the accessory body 12, and when the accessory body 12 is assembled to the main body shell 11, the first rotation limiting convex portion 122 can be rotatably inserted into the first rotation limiting notch 115. With such a structure, the reliability of the rotation of the accessory body relative to the main body shell 11 can be improved by utilizing the cooperation between the first rotation limiting convex portion 122 and the first rotation limiting notch 115, and the accessory body 12 is not likely to fall off when rotating. At the same time, the first inner cylinder 114 can provide protection for the internal sensing element to prevent the problem of users accidentally inserting accessories with too large specifications and damaging the sensing element.
[0047] Preferably, the first magnetic attraction component 1102 is an iron ring, and the second magnetic attraction component 1202 is a magnet. In addition, the first magnetic attraction component 1102 and the second magnetic attraction component 1202 can also be magnets.
[0048] A first bracket 112 is installed at the center of the main body shell 11 , and the sensing element 111 is installed on the first bracket 112 . The multiple sensing elements are connected to the first circuit board 113 via wired connections; alternatively, the multiple sensing elements can be integrated on the first circuit board 113 .
[0049] It should be noted that the sensing element is a Hall switch, and the annular trigger is an annular magnet; the annular magnet generates a magnetic field, and when the annular magnet is aligned with the Hall switch, the magnetic field exerts a force on the Hall switch, thereby generating a potential difference on both sides of the Hall element. By measuring the magnitude of this potential difference, the magnetic field strength of the magnet can be indirectly obtained, and the effect of identifying the annular magnet can be obtained.
