Description

Technical Field

[0001] The utility model belongs to the technical field related to scanning instruments, and particularly relates to a scanning head. Background Art

[0002] Currently, most of the existing scanning heads are powered by directly connecting to a power source through a power cable and a power adapter, and a small number of scanning heads are powered by external batteries.

[0003] It is understandable that when using a power cable and a power adapter to directly connect to the power supply, the plug of the power cable needs to be always plugged into the power socket so that the power socket can keep supplying power to the scanning head. This will make the scanning head dependent on the power socket when in use. The scanning head cannot be moved anytime and anywhere, and it is also unable to cope with emergencies such as power outages, making the scanning head unusable in harsh environments. When using an external battery for power supply, the battery cable and battery box that come with the external battery will make the scanning head very bulky as a whole, which does not conform to the development trend of simplicity and refinement of the scanning head, and the external battery also needs to be maintained. Therefore, it is particularly necessary to provide a new power supply method to power the scanning head. Utility Model Content

[0004] In view of this, it is necessary to provide a scanning head for solving the above technical problems.

[0005] A scanning head, comprising:

[0006] The scanning head body comprises a scanning head body and a housing, wherein the scanning head body is arranged inside the housing;

[0007] The battery module is arranged inside the housing and electrically connected to the scanning head body, and is used to supply power to the scanning head body.

[0008] It can be understood that the battery mold that supplies power to the scanning head body is arranged inside the casing, so that the scanning head can make full use of the internal space of the casing for power supply. In this way, the built-in power supply of the scanning head can be realized, which not only does not affect the overall volume of the scanning head and meets the development trend of simplicity and sophistication of the scanning head, but also facilitates the user to use and carry the scanning head; at the same time, the battery module is used to power the scanning head body, so that the operation of the scanning head will not be affected by emergencies such as power failures in the working environment, so as to adapt to working in harsh environments and expand the application scenarios of the scanning head.

[0009] In one embodiment, the battery module includes a battery protection board, a battery and a battery compartment cover, the battery protection board is connected to a conductive sheet, and the battery protection board can be electrically connected to the battery through the conductive sheet; the battery compartment cover is arranged on the outside of the battery and is detachably connected to the housing;

[0010] Wherein, the battery protection board is electrically connected to the scanning head body.

[0011] In one of the embodiments, a circuit protection module is integrated on the battery protection board. When the power supply from the battery to the battery protection board is abnormal, the circuit protection module can cut off the power supply circuit between the battery and the battery protection board.

[0012] It can be understood that the circuit protection module is used to cut off the power supply circuit between the battery and the battery protection board when power supply abnormality occurs. In this way, it can protect the battery protection board and extend the service life of the battery protection board.

[0013] In one embodiment, a circuit boost module is also integrated on the battery protection board, and the battery protection board can supply power to the scanning head body through the circuit boost module;

[0014] The voltage when the battery protection board supplies power to the scanning head body is greater than the voltage when the battery supplies power to the battery protection board.

[0015] It is understandable that the circuit boost module is used to increase the voltage when the battery is powered, so that the voltage usage requirements of the scanning head body when it is working can be met, so that the scanning head can be suitable for low-voltage batteries.

[0016] In one of the embodiments, the battery protection board is further integrated with a first detection sensor, which can detect the capacity of the battery and generate a first feedback signal.

[0017] It is understandable that the first detection sensor is used to detect the capacity of the battery, so that signal feedback of the battery capacity can be achieved.

[0018] In one of the embodiments, the battery protection board is further integrated with a second detection sensor, which can detect the transmission enable when the battery supplies power to the battery protection board and generate a second feedback signal.

[0019] It is understandable that the second detection sensor is used to detect the transmission enable when the battery is powered, so that signal feedback can be provided on the working state when the battery supplies power to the battery protection board.

[0020] In one of the embodiments, a buckle is formed on one of the housing and the battery compartment cover, and a slot is formed on the other, and the buckle can be engaged with the slot to limit the battery compartment cover to the housing.

[0021] It can be understood that the positioning of the battery compartment cover on the housing is achieved by utilizing the snap fit between the snap buckle and the slot, so that the battery compartment cover can be easily assembled and disassembled relative to the housing.

[0022] In one of the embodiments, an elastomer is disposed on the housing and / or the battery compartment cover. The elastomer is disposed between the housing and the battery compartment cover and can be deformed under pressure, and the battery compartment cover can pop open from the housing under the push of the deformed elastomer.

[0023] It is understandable that the elastic body is used to bounce the unlocked battery compartment cover away from the housing, so that the battery compartment cover can be easily removed from the housing.

[0024] In one of the embodiments, a pull rope is connected to the housing, the pull rope portion is arranged between the battery and the housing, and the battery can be removed from the housing under the drive of the pull rope.

[0025] It is understandable that the battery can be easily removed from the housing by using a pull cord to drive the battery out of the housing.

[0026] In one embodiment, the housing has a handle portion, and the handle portion can be held by a human hand;

[0027] The battery module is arranged in the area where the handle portion is located, wherein the battery module includes a battery compartment cover, and the battery compartment cover is arranged on the outer side of the handle portion.

[0028] It is understandable that the battery compartment cover of the battery module is arranged on the outside of the handle portion of the housing, so that it is convenient to replace the batteries in the battery module and improve the internal space utilization of the scanning head.

[0029] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0030] The scanning head for which protection is sought in the present application has a battery mold for supplying power to the scanning head body disposed inside the casing, so that the scanning head can make full use of the internal space of the casing for power supply. In this way, the built-in power supply of the scanning head can be achieved, which not only does not affect the overall volume of the scanning head and meets the development trend of simplicity and sophistication of the scanning head, but also makes it convenient for users to use and carry the scanning head. At the same time, the scanning head body is powered by a battery module, so that the operation of the scanning head will not be affected by emergencies such as power failures in the working environment, so as to adapt to working in harsh environments and expand the application scenarios of the scanning head.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] The scanning head 100 for which protection is requested in the present application is specifically a scanning head applied to a handheld three-dimensional scanner.

[0042] like Figure 1 As shown, a scanning head 100 provided in an embodiment of the present application includes a scanning head body 10 and a battery module 20. The scanning head body 10 includes a scanning head body 11 and a housing 12. The scanning head body 11 is disposed inside the housing 12. The battery module 20 is disposed inside the housing 12 and is electrically connected to the scanning head body 11, and is used to supply power to the scanning head body 11. Here, the scanning head body 11 is the power-consuming part of the scanning head 100 when it is working.

[0043] It can be understood that the battery module 20 that supplies power to the scanning head body 11 is arranged inside the casing 12, so that the scanning head 100 can make full use of the internal space of the casing 12 for power supply. In this way, the built-in power supply of the scanning head 100 can be realized, which not only does not affect the overall volume of the scanning head 100, and meets the development trend of simplicity and refinement of the scanning head 100, but also facilitates the user to use and carry the scanning head 100; at the same time, the battery module 20 is used to power the scanning head body 11, so that the operator does not need an external power cord when using the scanning head 100 to work, thereby improving the convenience of using the scanning head 100, and the operation of the scanning head 100 will not be affected by emergencies such as power failures in the working environment, so as to adapt to working in harsh environments, thereby expanding the application scenarios of the scanning head 100.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the housing 12 has a handle 120, which can be held by a human hand; the battery module 20 is arranged in the area where the handle 120 is located, wherein the battery compartment cover 23 of the battery module 20 is arranged on the outside of the handle 120. In this way, it is convenient to replace the battery 22 in the battery module 20, and improve the internal space utilization of the scanning head 100. Here, the outside of the handle 120 specifically refers to the side of the channel where the handle 120 is located on the scanning head 100 for a human hand to reach in and grab the handle 120. It should be noted that after the scanning head 100 is miniaturized, the support structure requirements of the handle 120 on the scanning head 100 will also be reduced, and the battery module 20 is arranged in the handle 120 on the housing 12 for a human hand to hold, which can meet the use requirements of the scanning head 100.

[0045] like Figure 1 As shown, in one embodiment, the battery module 20 includes a battery protection board 21, a battery 22 and a battery compartment cover 23. The battery protection board 21 is connected to a conductive sheet 211, and the battery protection board 21 can be electrically connected to the battery 22 through the conductive sheet 211; the battery compartment cover 23 is arranged on the outside of the battery 22 and is detachably connected to the housing 12; wherein the battery protection board 21 is electrically connected to the scanning head body 11. That is to say, when the battery module 20 is working, the battery 22 can supply power to the scanning head body 11 through the battery protection board 21. Here, the battery protection board 21 is set as a circuit board.

[0046] As can be seen from the above, the housing 12 is used to directly support the battery protection board 21 and the battery 22. This can reduce the possibility of the battery module 20 becoming loose or moving when assembled on the housing 12, thereby improving the structural stability of the scanning head 100; on the other hand, it can also reduce the redundant space of the scanning head 100, making the structure of the scanning head 100 more compact.

[0047] In one embodiment, a via pad (not shown) and a bolt hole (not shown) are reserved on the battery protection board 21. The via pad is used to weld the conductive sheet 211, and the bolt hole can be passed through by fasteners such as screws and bolts to fix the battery protection board 21 to the housing 12. Here, there are two conductive sheets 211, and the parts of the two conductive sheets 211 away from the battery protection board 21 can abut against the positive and negative electrodes of the battery 22 to fix the battery 22 to the position between the two conductive sheets 211, and realize the electrical connection between the battery 22 and the battery protection board 21. It should be noted that the conductive sheet 211 is set as a metal spring.

[0048] like Figure 4 As shown, in one embodiment, a circuit protection module 212 is integrated on the battery protection board 21. When the power supply from the battery 22 to the battery protection board 21 is abnormal, the circuit protection module 212 can cut off the power supply circuit between the battery 22 and the battery protection board 21, so as to protect the battery protection board 21 and extend the service life of the battery protection board 21. Here, the circuit protection module 212 includes a battery protection chip (not shown) and a field effect transistor (not shown). By using the operation of the battery protection chip and the field effect transistor, the power supply circuit between the battery 22 and the battery protection board 21 is cut off when the power supply from the battery 22 to the battery protection board 21 is abnormal. It should be noted that the specific structure and working principle of the battery protection chip and the field effect transistor can adopt the existing conventional method, which will not be elaborated here.

[0049] like Figure 4As shown, in one embodiment, a circuit boost module 213 is also integrated on the battery protection board 21, and the battery protection board 21 can supply power to the scanning head body through the circuit boost module 213; wherein, the voltage when the battery protection board 21 supplies power to the scanning head body 11 is greater than the voltage when the battery 22 supplies power to the battery protection board 21. In other words, the circuit boost module 213 can boost the voltage when the battery 22 supplies power to meet the voltage usage requirements of the scanning head body 11 when it is working. This enables the scanning head 100 to be suitable for low-voltage batteries. Here, the above-mentioned circuit boost module 213 includes a boost chip (not shown in the figure), which can increase the voltage of the battery 22 from 3.6V to 14.3V and supply power to the scanning head body 11. It should be noted that the specific structure and working principle of the above-mentioned boost chip can adopt the existing conventional method, which will not be elaborated here.

[0050] like Figure 4 As shown, in one embodiment, a first detection sensor 214 is also integrated on the battery protection board 21, and the first detection sensor 214 can detect the capacity of the battery 22 and generate a first feedback signal. In other words, the battery module 20 can provide signal feedback on the capacity of the battery 22 when it is working. It should be noted that the specific structure of the first detection sensor 214 and the working principle of how to detect the capacity of the battery 22 and generate the first feedback signal when working can all adopt existing conventional methods, which will not be elaborated here.

[0051] like Figure 4 As shown, in one embodiment, a second detection sensor 215 is also integrated on the battery protection board 21, and the second detection sensor 215 can detect the transmission enable when the battery 22 supplies power to the battery protection board 21 and generate a second feedback signal. In other words, when the battery module 20 is working, it can provide signal feedback on the working state when the battery 22 supplies power to the battery protection board 21. It should be noted that the specific structure of the above-mentioned second detection sensor 215 and the working principle of how to detect the transmission enable when the battery 22 supplies power to the battery protection board 21 and generate the second feedback signal when working can all adopt the existing conventional methods, which will not be elaborated here.

[0052] like Figure 2 , Figure 3As shown, in one embodiment, one of the housing 12 and the battery compartment cover 23 is formed with a buckle 121, and the other is provided with a slot 231, and the buckle 121 can be engaged with the slot 231 to limit the battery compartment cover 23 to the housing 12. In this way, when the battery compartment cover 23 needs to be assembled to the housing 12, one end of the battery compartment cover 23 can be first inserted into the housing 12, and the battery compartment cover 23 can be driven to cover the housing 12, and then the assembly of the battery compartment cover 23 on the housing 12 is realized by the engagement between the buckle 121 and the slot 231, so that the battery compartment cover 23 can be easily disassembled and assembled relative to the housing 12.

[0053] In this embodiment, the buckle 121 is provided on the housing 12, and the slot 231 is provided on the battery compartment cover 23. The buckle 121 rotates on the housing 12 after being pressed by a human hand, which can eliminate the position interference between the buckle 121 and the part of the battery compartment cover 23 where the slot 231 is provided, and then the battery compartment cover 23 is driven to cover the housing 12. After that, the human hand releases the pressing of the buckle 121, so that the buckle 121 and the slot 231 can be engaged. Of course, in other embodiments, the buckle can also be provided on the battery compartment cover 23, and the slot can be provided on the housing 12, which will not be elaborated here.

[0054] like Figure 3 As shown, in one embodiment, an elastic body 122 is provided on the housing 12 and / or the battery compartment cover 23. The elastic body 122 is provided between the housing 12 and the battery compartment cover 23 and can be deformed under pressure, and the battery compartment cover 23 can be ejected from the housing 12 under the push of the deformed elastic body 122, so that once the battery compartment cover 23 is released from the snap fit between the buckle 121 and the slot 231 on the housing 12, the battery compartment cover 23 can be automatically ejected from the housing 12 under the push of the elastic body 122, so that the battery compartment cover 23 can be easily removed from the housing 12. Here, there are two elastic bodies 122, and the two elastic bodies 122 are symmetrically arranged on both sides of the housing 12, so that there are two points of action when the battery compartment cover 23 is ejected from the housing 12, so that it can be ensured that the battery compartment cover 23 can be ejected from the housing 12 under the push of the elastic body 122. Here, the elastic body 122 can be specifically configured as a rubber body, a silicone body, etc.

[0055] like Figure 3As shown, in one embodiment, a pull cord 123 is connected to the housing 12, and the pull cord 123 is partially disposed between the battery 22 and the housing 12, and the battery 22 can be pulled out of the housing 12 under the drive of the pull cord 123. In this way, when people replace the battery 22, they can pull the pull cord 123 by hand, and the battery can be easily pulled out of the housing 12 by using the pull cord 123, so that the battery 22 can be easily removed from the housing 12. Here, the pull cord 123 is set to a flat structure, and the part of the pull cord 123 that extends out of the battery 22 can be completely covered by the battery compartment cover 23, so as not to affect the overall appearance of the scanning head 100.

[0056] In summary, the scanning head 100 of the present application sets the battery module 20 for powering the scanning head body 11 inside the casing 12, so that the scanning head 100 can make full use of the internal space of the casing 12 for power supply. In this way, the built-in power supply of the scanning head 100 can be realized, which not only does not affect the overall volume of the scanning head 100, and meets the development trend of simplicity and sophistication of the scanning head 100, but also facilitates the user to use and carry the scanning head 100; at the same time, the battery module 20 is used to power the scanning head body 11, so that the operation of the scanning head 100 will not be affected by emergencies such as power failures in the working environment, so as to adapt to working in harsh environments, thereby expanding the application scenarios of the scanning head 100.

[0057] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
