[0033] In the following description, with reference to the accompanying drawings, several embodiments of the present application are described. It should be understood that other embodiments may also be used, and mechanical composition, structure, electrical and operational changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used here are only to describe specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "below", "lower", "above", "upper", etc., may be used in the text to facilitate the description of the relationship between an element or feature shown in the figure and another element or feature.

[0034] Although the terms first, second, etc. are used in some instances to describe various elements in this document, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first measuring element may be referred to as a second measuring element, and similarly, a second measuring element may be referred to as a first measuring element without departing from the scope of the various described embodiments. The first measuring element and the second measuring element are both describing a certain measuring element, but unless the context clearly indicates otherwise, they are not the same measuring element. Similar situations also include a first preset position relationship and a second preset position relationship, etc.

[0035] In view of the technical problems mentioned in the background technology, the present application discloses a measuring device and a measuring equipment, which configures at least the area surrounding the control device in the rear shell that accommodates the control device as an insulating material to block the heat generated by the control device from being transmitted to the front shell used to configure the first and second measuring elements, so as to avoid the heat generated by the control device affecting the relative position relationship between the measuring components, thereby ensuring the measurement accuracy.

[0036] The measuring device is a device for measuring the geometric features of the object to be measured. In one embodiment, the object to be measured is, for example, a component, assembly, or mold in the fields of electronics, optics, industrial production, or medical equipment, and the geometric features are, for example, the size, shape, surface quality, and / or texture of the object to be measured.

[0037] For example, the measuring device can be configured as a three-coordinate measuring machine, and further, can be configured as an articulated arm three-coordinate measuring machine. In the following embodiments, the measuring device is configured as an articulated arm three-coordinate measuring machine as an example, which should not be understood as a limitation to the present application.

[0038] See also Figure 1 , which is a schematic diagram of the structure of a measuring device in one embodiment of the present application, as shown in the figure, the measuring device includes an articulated arm 1, a base 2, and a measuring device 3. The articulated arm 1 has a proximal end and a distal end relative to each other, the proximal end of which is connected to the base 2, and the distal end of which is configured with the measuring device 3 for measuring the object to be measured. It should be noted that Figure 1 The measuring device connected to the distal end of the articulated arm 1 is only an exemplary description. In other examples, the measuring device may also be configured to include other structures or be composed of other structures. In addition, in subsequent embodiments, in order to clearly illustrate the relative positions of various parts, structures, assemblies, mechanisms, components, equipment, or devices in the measuring device, the proximal end and the distal end of the articulated arm are used as the reference for distinction. The side of each part, structure, assembly, mechanism, component, equipment, or device that is relatively close to the proximal end of the articulated arm is called the proximal end (also called the proximal side), and the side that is relatively close to the distal end of the articulated arm is called the distal end (also called the distal side).

[0039] In one embodiment, the articulated arm 1 provides the measuring device with the freedom to move in space, so that the measuring device can move to the object to be measured for measurement. For example, the measuring device can move to the point to be measured aligned with the object to be measured for measurement; wherein the point to be measured corresponds to the position or area to be measured on the object to be measured, and the point to be measured is aligned with the position where the measuring device is located so that the point to be measured can be measured, which can be, for example, the measuring device can move to the top of the object to be measured for non-contact measurement or the measuring device moves to contact with the point to be measured of the object to be measured for contact measurement.

[0040] In one embodiment, if Figure 1 As shown, the articulated arm 1 includes a first arm component 10, a second arm component 11, and seven shaft assemblies, each of which can provide rotary rotation or hinge rotation. Figure 1The seven axis components are respectively the first axis component 12, the second axis component 13, the third axis component 14, the fourth axis component 15, the fifth axis component 16, the sixth axis component 17, and the seventh axis component 18. The first axis component 12 is connected to the base 2, and provides a rotary rotation around the axis of the base 2 as the center. The second axis component 13 is connected to the proximal end of the first arm component 10 and connected to the first axis component 12. The second axis component 13 provides a hinge rotation around an axis perpendicular to the first arm component 10 (which may correspond to the axis of the second axis component). The third axis component 14 is connected to the distal end of the first arm component 10, and provides a rotary rotation around the axis of the first arm component 10 as the center. The fourth axis component 15 is connected to the proximal end of the second arm component 11 and connected to the third axis component 14. The fourth axis component 15 provides a hinge rotation around an axis perpendicular to the second arm component 11 (which may correspond to the axis of the fourth axis component 15). The fifth axis assembly 16 is connected to the distal end of the second arm component 11, and provides a rotational rotation centered on the axis of the second arm component 11. The sixth axis assembly 17 is connected to the proximal end of the second arm component 11 and is connected to the fifth axis assembly 16. The sixth axis assembly 17 provides a hinged rotation around an axis perpendicular to the second arm component 11 (which may correspond to the axis of the sixth axis assembly 17). The seventh axis assembly 18 is connected to the measuring device, and the seventh axis assembly 18 provides a rotational rotation of the measuring device.

[0041] In some embodiments, the axis assemblies (e.g., the first axis assembly 12 and the second axis assembly 13) that are combined together to connect the first arm member 10 to the base 2 are collectively referred to as the first joint mechanism. Similarly, the axis assemblies (e.g., the third axis assembly 14 and the fourth axis assembly 15) that are combined together to connect the first arm member 10 and the second arm member 11 are collectively referred to as the second joint mechanism. The axis assemblies (e.g., the fifth axis assembly 16, the sixth axis assembly 17, and the seventh axis assembly 18) that are combined together to connect the measuring device to the second arm member 11 are collectively referred to as the third joint mechanism. In some embodiments, the positions of the axis assemblies and the number of axis assemblies included in each joint mechanism may also be different from those in FIG. Figure 1 Different from what is shown in the figure, for example, the third axis assembly 14 can be moved to the proximal end of the first arm member 10, and together with the first axis assembly 12 and the second axis assembly 13, serve as the first joint mechanism, and the fourth axis assembly 15 serves as the second joint mechanism. Of course, other methods of combining the axis assemblies can also be used, which will not be described in detail here.

[0042] like Figure 1 In the embodiment shown, the articulated arm 1 is provided with seven shaft assemblies to provide seven axis rotations. Figure 1 The measuring device in the illustrated embodiment is referred to as a seven-axis coordinate measuring machine.

[0043] It should be understood that Figure 1 The configuration of two arm components and seven axis assemblies in the middle articulated arm is merely an exemplary description, and the present application is not limited thereto. The articulated arm can be configured with any number of arm components, and the axis assemblies connecting adjacent arm components, arm components and bases, or arm components and measuring devices can also be configured with any number. The articulated arm can provide rotation along more or less than seven axes, as long as the articulated arm includes at least one arm component connected to the base and an axis assembly connected between the base and the arm component to provide hinged rotation.

[0044] In one embodiment, the arm component in the articulated arm may be configured as an elongated cylindrical shape and may be made of a suitable rigid material, for example, a lightweight and high-strength metal alloy such as an aluminum alloy, a magnesium alloy, or a carbon composite material.

[0045] In one embodiment, each axis assembly includes an encoder, which can be configured as an angle encoder, which can provide rotation information of the corresponding axis assembly, so that the rotation information provided by the encoders of all axis assemblies can determine the position of the measuring device relative to the base. Further, the main control device configured in the base can determine the three-dimensional coordinates of the point to be measured based on the position of the measuring device relative to the base and the acquired position data.

[0046] like Figure 1 As shown, the base 2 is used to be installed on a measuring platform. In this way, the base 2 can be used as a connecting part so that the articulated arm 1 can rotate in space with the measuring platform as the base point, so that the measuring device can be freely oriented in space and positioned near the object to be measured or positioned in contact with the object to be measured for measurement. In one example, the base 2 may include a mounting device 20, and the mounting device 20 allows the measuring device to be removably set on the measuring platform, and the measuring platform is, for example, an inspection table, a processing platform, a wall, a ground, or a tripod. For example, the mounting device 20 can be configured as a threaded ring structure, and the measuring device can be placed on the measuring platform for measurement by tightening the threaded ring structure on the measuring platform, and the measuring device can be removed from the measuring platform or the direction of the measuring device can be adjusted by loosening the threaded ring structure on the measuring platform. Furthermore, an operating part can be configured on the threaded ring structure to facilitate tightening or loosening operations.

[0047] In one embodiment, if Figure 2 As shown, it is a schematic diagram of the structure of the measuring device configured on the measuring device in one embodiment of the present application. As shown in the figure, the measuring device 3 includes a base 36, and the base 36 is connected to the distal end of the articulated arm 1. Further, Figure 1 It is connected to the seventh axis assembly 18 so that the measuring device 3 can be configured at the distal end of the articulated arm 1.

[0048] In one embodiment, the measuring device 3 further comprises a probe, which is detachably mounted on the base 36. In one example, an interface unit may be configured on the base 36, and the interface unit includes a probe interface module and a trigger component interface module. The probe interface module is configured as at least one, and the probe may be detachably mounted on the base 36 through one probe interface module, and more probe interface modules may be used to connect more probes. The trigger component interface module is used to connect a trigger component, and the trigger component may be, for example, Figure 1 The handle shown may also be a keypad.

[0049] In one embodiment, the probe interface module is configured as one, that is, one probe can be configured on the base 36. Figure 2 As shown, the probe interface module is configured as two, wherein the first probe interface module 361 can be configured at the front end or front of the substrate 36, and the second probe interface module 360 ​​can be configured at the side of the substrate 36. In the present embodiment, the probe interface module is configured as two (360, 361) to allow detachable connection of one or two probes. In one example, a probe can be connected, and the probe can be selectively connected to the first probe interface module 361 or the second probe interface module 360. In another example, two probes can be connected, respectively connected to the first probe interface module 361 and the second probe interface module 360.

[0050] In one embodiment, the probe may be configured as follows Figure 2 The contact probe 37 shown can be moved to contact the measured point of the object to be measured to perform contact measurement. In some examples, the contact probe is configured to include a contact probe having different ends that can physically contact the object to be measured, including but not limited to a ball, touch-sensitive, curved, or extended probe.

[0051] In one embodiment, the probe may be configured as a non-contact probe. Specifically, the non-contact probe may include a light source (e.g., a laser) and an optical sensor (e.g., a camera), and may obtain coordinate data of the object to be measured by a triangulation method. The non-contact probe may be configured, for example, as follows Figures 3 to 10 The structure described in any embodiment in its related description.

[0052] It should be noted that Figure 1 The illustrated embodiment is described by taking the measuring device 3 connected to the distal end of the articulated arm 1 through its base 36 as an example, which does not limit the structure and connection method of the measuring device of the present application. Figure 1 Instead of using the base 36 shown in the figure, the probe is used as a measuring device or the probe is used in combination with other components as a measuring device, for example, as described later. Figures 3 to 10 The probe and its related structures shown in any embodiment in the related description can also be called a measuring device for measurement, or cooperate with a handle to form a handheld measuring device for measurement, etc.

[0053] In one embodiment, see Figures 3 to 5 , Figure 3 and Figure 4 They are schematic diagrams showing the structure of the probe in different viewing angles in one embodiment of the present application. Figure 5 The schematic diagram of the disassembled structure of the probe in one embodiment of the present application is shown. As shown in the figure, the probe includes a first measuring element 31, a second measuring element 32, a control device 33, and a shell component 34. The shell component is used to set the first measuring element 31, the second measuring element 32, and the control device 33. At least the area around the control device 33 in the shell component 34 is configured as a heat-insulating material to maintain the preset position relationship between the first measuring element 31 and the second measuring element 32. It should be understood that the probe can form a measuring device alone or in combination with other components as described above. In view of this, in some embodiments, such as Figures 3 to 5 The probe described in the embodiments may also be referred to as a measuring device.

[0054] In one embodiment, the first measuring element 31 and the second measuring element 32 cooperate to measure the object to be measured. The first measuring element 31 is exemplified as a camera (e.g., a camera), and the second measuring element 32 is exemplified as a laser. In this embodiment, the second measuring element 32 emits a laser (e.g., a line laser) toward the object to be measured, and the object to be measured modulates the laser. The first measuring element 31 captures the modulated laser so that the control device 33 or / and the main control device in the base can perform relevant calculations based on the image data captured by the first measuring element 31 to obtain the geometric features of the object to be measured.

[0055] In a specific embodiment, the measurement principle is described in detail by taking the first measuring element 31 as a camera device and the second measuring element 32 as a laser as an example. Figure 6, shows a schematic diagram of the first measuring element and the second measuring element in cooperation with each other for measurement in one embodiment of the present application. As shown in the figure, the measuring device performs measurement based on the direct oblique laser triangulation method. During measurement, the second measuring element 32 emits laser in a direction perpendicular to the object D to be measured, and the first measuring element 31 photographs the modulated laser in a direction not perpendicular to the object D to be measured. For another example, when the measuring device performs measurement based on the oblique direct laser triangulation method, the second measuring element 32 emits laser in a direction not perpendicular to the object to be measured, and the first measuring element 31 photographs the modulated laser in a direction perpendicular to the object to be measured.

[0056] It should be noted that, in other examples, according to different principles of measuring the object to be measured, more than two measuring elements may be configured, and the types of measuring elements may also be selectively configured, for example, the first measuring element and the second measuring element may also be configured as camera devices or as lasers. In the following embodiments, the first measuring element is a camera device and the second measuring device is a laser.

[0057] The control device 33 is electrically connected to the first measuring element 31 and the second measuring element 32, respectively, and is used to control the first measuring element 31 and the second measuring element 32. In one embodiment, the control device 33 controls the second measuring element 32 to emit laser according to preset laser parameters and controls the first measuring element 31 to acquire image data according to preset shooting parameters. The preset laser parameters include: repetition frequency, pulse width, or laser power, etc., and the preset shooting parameters include: aperture, exposure time, or sensitivity, etc. Further, the control device 33 can also perform data processing on the image data captured by the first measuring element 31.

[0058] In one embodiment, the control device 33 includes a memory and a processor connected to the memory.

[0059] In some embodiments, the memory is used to store at least one program, and the at least one program can be executed by the processor to control the first measuring element and the second measuring element, and perform data processing on image data captured by the first measuring element.

[0060] Here, the memory includes a read-only memory, a random access memory, or a non-volatile memory, etc. For example, the memory includes a flash memory device or other non-volatile solid-state storage device. In some embodiments, the memory may also include a memory away from one or more processors, such as a network attached memory accessed via an RF circuit or an external port and a communication network, wherein the communication network may be the Internet, one or more intranets, a local area network, a wide area network, a storage area network, etc., or a suitable combination thereof.

[0061] In some embodiments, the processor is configured as one or more. The processor is operable to perform data read and write operations with the memory. The processor includes one or more general-purpose microprocessors, one or more application-specific processors (ASICs), one or more digital signal processors, one or more field programmable logic arrays (FPGAs), or any combination thereof.

[0062] The control device 33 may further include a communication unit. In some embodiments, the communication unit is configured as at least one, for example, the communication unit includes a network communication unit, which is a device for data transmission using a wired or wireless network, examples of which include but are not limited to: an integrated circuit including a network card, a local area network module such as a WiFi module or a Bluetooth module, a wide area network module such as a mobile network, etc.

[0063] In one embodiment, if Figure 5 As shown, the housing assembly 34 includes a front housing 340, a rear housing 341, and a cover 342. The side of the housing assembly 34 where the first measuring element 31 and the second measuring element 32 are installed is the front side of the housing assembly 34, and the side opposite to the front side is the rear side of the housing assembly 34. In the subsequent embodiments, in order to clearly explain the relative positions of various components, structures, assemblies, mechanisms, components, equipment, or devices in the housing assembly 34, the front side and the rear side of the housing assembly 34 are used as references for distinction. The side of each component, structure, assembly, mechanism, component, equipment, or device that is relatively close to the front side of the housing assembly 34 is called the front side (also called the front end), and the side that is relatively close to the rear side of the housing assembly 34 is called the far rear side (also called the rear end).

[0064] See also Figure 7 Combined with Figure 5 , Figure 7 Shown is a schematic diagram of the structure of the front shell in one embodiment of the present application. As shown in the figure, a first mounting portion 34010 and a second mounting portion 34020 are formed on the front shell 340. The first mounting portion 34010 is used to configure the first measuring element 31, and the second mounting portion 34020 is used to configure the second measuring element 32.

[0065] In one embodiment, the first mounting portion 34010 and the second mounting portion 34020 are, for example, hole structures, and the ends of the first measuring element 31 and the second measuring element 32 are located in the hole structures to achieve connection with the front housing 340. Figure 5 As shown, the front end of the first measuring element 31 is located in the hole structure corresponding to the first mounting portion 34010, and the rear end of the first measuring element 31 is located in the support member 3411 of the rear shell 341. The first measuring element 31 is fixed by the cooperation of the rear shell 341, and the rear end of the second measuring element 32 is located in the hole structure corresponding to the second mounting portion 34020 to fix the second measuring element 32.

[0066] In one embodiment, the first measuring element and the second measuring element are disposed on the front housing in a first preset position relationship, wherein the first preset position relationship includes a preset distance between the first and second measuring elements and a preset angle between the first and second measuring elements.

[0067] The preset distance between the first and second measuring elements and the preset angle between the first and second measuring elements are the distance and angle between the first and second measuring elements when the first and second measuring elements are mounted on the front housing. In one embodiment, the preset angle is the angle between the optical axes of the first and second measuring elements, for example, Figure 3 The angle θ shown is shown in FIG. The preset distance is the baseline length of the first and second measuring elements, and the baseline is a line segment connecting the optical centers of the first and second measuring elements.

[0068] In one embodiment, the front housing 340 is configured to include a first plane structure 3401, a second plane structure 3402, and a bending structure 3403, wherein the bending structure 3403 is connected between the first plane structure 3401 and the second plane structure 3402, and is used to make the normal lines of the two planes form the preset angle. Specifically, the bending structure 3403 is connected to the first plane structure 3401 through a first bending angle, and is connected to the second plane structure 3402 through a second bending angle. The first bending angle and the second bending angle need to be designed so that the first plane structure 3401 and the second plane structure 3402 are not on the same line, so that the normal lines of the two planes can form the preset angle. In this way, when the first measuring element 31 and the second measuring element 32 are respectively arranged vertically on the first plane structure 3401 and the second plane structure 3402, the first measuring element 31 and the second measuring element 32 can be arranged on the front housing 340 at the preset angle. The preset distance between the first measuring element 31 and the second measuring element 32 is determined by factors such as the lengths of the first planar structure 3401 and the second planar structure 3402 , and the installation positions of the first measuring element 31 and the second measuring element 32 on the first planar structure 3401 and the second planar structure 3402 , respectively.

[0069] It should be noted that the bending structure may not be provided in the front shell, and the first plane structure and the second plane structure may be directly connected at a certain angle to serve as the front shell structure. In addition, the structure of the front shell may be reconfigured according to different measurement principles, for example, the positional relationship between the first plane structure and the second plane structure may be reconfigured.

[0070] In one embodiment, the front housing is configured as a metal housing made of a metal material. Examples of the metal material include aluminum alloy, magnesium alloy, aluminum-magnesium alloy, stainless steel, etc. Configuring the front housing as a metal housing can ensure that the front housing has good rigidity, thereby not only maintaining the first preset relationship between the first and second measuring elements stable, but also protecting internal components to reduce the risk of product damage.

[0071] In one embodiment, the rear housing 341 is located at the rear side of the front housing 340 and connected to the front housing 340. The front housing 340 and the rear housing 341 may be detachably connected or non-detachably connected. In one example, the front housing 340 and the rear housing 341 are detachably connected, for example, the front housing 340 and the rear housing 341 are detachably connected by screws, rivets, a snap-fit ​​structure, etc. In this way, it is convenient to install and repair the first measuring element 31, the second measuring element 32, and the control device 33 on the housing assembly 34. In another example, the front housing 340 and the rear housing 341 are non-detachably connected, for example, the front housing 340 and the rear housing 341 are connected by glue or other materials. In this way, the weight of the connecting member is reduced, and the weight of the overall structure of the front housing 340 and the rear housing 34 can be reduced.

[0072] In one embodiment, see Figure 8 Combined with Figure 5 , Figure 8 The structure diagram of the rear housing in one embodiment of the present application is shown. As shown in the figure, the rear housing 341 has a receiving cavity 3410. The receiving cavity 3410 is used to receive the control device 33. For example, the control device 33 is located at the rear side of the receiving cavity 3410.

[0073] Since the control device 23 continuously generates heat during use of the measuring device, the heat generated by the control device 23 is continuously transferred to the front shell 340 through the rear shell 341. Therefore, the front shell 340 is heated and continuously expands, resulting in a significant change in the first preset position relationship between the first measuring element 31 and the second measuring element 32, thereby seriously affecting the measurement accuracy of the object to be measured by using the first measuring element 31 and the second measuring element 32 to cooperate with each other.

[0074] To this end, at least the area surrounding the control device in the rear housing is configured with a heat insulating material to prevent the heat generated by the control device from being transmitted to the front housing, thereby maintaining the first preset position relationship between the first and second measuring elements. It should be noted that maintaining the first preset position relationship does not require the first preset position to remain unchanged, as long as a slight change in the first preset position relationship does not affect the measurement accuracy.

[0075] In one embodiment, see Fig. 9 , which is a schematic diagram showing that the control device is configured in the rear housing in one embodiment of the present application, and it is possible to only Fig. 9The area in the rear shell 341 shown in the figure that is in contact with the control device 33 is configured as a heat insulating material, or the area in the rear shell 341 that extends to a preset width based on the area in contact with the control device 33 is set as a heat insulating material, as long as the area in the rear shell 341 where the heat insulating material is set includes the area in contact with the control device 33.

[0076] Furthermore, the entire rear shell can be configured as a heat-insulating material, which not only ensures the heat-insulating effect to more effectively block the heat generated by the control device from being transmitted to the front shell, but also reduces the difficulty of processing the rear shell.

[0077] In one embodiment, the thermal insulation material is a material with a low thermal expansion coefficient. For example, the thermal expansion coefficient of the thermal insulation material is 0.1×10 -6 (m / mK) to 4×10 -6 (m / mK). However, this is not limiting, and in other embodiments, the thermal insulation material may be selected by taking both strength and thermal expansion coefficient into consideration.

[0078] In one example, the heat insulating material is a carbon fiber material, which has a high hardness and a low thermal expansion coefficient, and can effectively block heat transfer and ensure the strength of the rear shell. In other examples, the heat insulating material can also be a ceramic material with a high hardness, such as silicon nitride ceramic material.

[0079] In one embodiment, see Figure 3 The rear housing 341 is also provided with an interface unit 35 which is in a second preset position relationship with the first measuring element 31 and the second measuring element 32. Figure 3 As shown, the second preset position relationship includes the distance and angle between the interface unit 35 and the first measuring element 31 when the interface unit 35 is configured on the rear housing 341, and the distance and angle between the interface unit 35 and the second measuring element 32. When the first measuring element 31, the second measuring element 32, and the interface unit 35 are configured on the rear housing 341 and the front housing in a fixed posture, the second preset position relationship is determined. In any embodiment in which at least the area surrounding the control device in the rear housing 341 is configured as a heat insulating material, the propagation of heat toward the interface unit 35 can also be blocked, thereby further ensuring that the second preset position relationship will not be changed due to heat.

[0080] In one embodiment, see Fig.10 , which is a schematic diagram of the structure in which the probe and the substrate are separated in one embodiment of the present invention. As shown in the figure, the interface unit 35 is used to connect the probe to the substrate 36. Specifically, it can be as follows Fig.10As shown, the interface unit 35 may include a connector 350, which is used to be locked or unlocked by the second probe interface module 360, so that the probe can be fixed on the base 36 or detached from the base 36. Further, the interface unit 35 is configured with a plurality of first positioning members 351 unevenly distributed along its circumference, and the second probe interface module 360 ​​is configured with a plurality of second positioning members 3600 equal to the number of the first positioning members 351, and the plurality of second positioning members 3600 and the plurality of first positioning members 351 have the same distribution rule in the circumferential direction, so that the interface unit 35 can be accurately positioned and installed on the second probe interface module 360. Fig.10 In the illustrated embodiment, the first positioning member 351 is a positioning hole, and the number of the positioning holes is three, and the second positioning member 3600 is a positioning rod, and the number of the positioning rods is also three.

[0081] In another embodiment, the interface unit 35 can be used to connect a trigger device, and after the trigger device locks the connector 350, the probe can be operated by triggering the trigger device. The trigger device is, for example, a handle or a keypad. In this embodiment, the interface unit 35 is connected to the handle to form a handheld scanner.

[0082] See also Figure 5 Combined with Figure 8 ,like Figure 5 and Figure 8 As shown, the cover 342 is located at the rear side of the rear housing 341, and the cover 342 is used to cover the rear housing 341 to close the accommodating cavity 3410. Specifically, the shape of the cover 342 matches the shape of the rear end of the rear housing 341 to close the accommodating cavity 3410.

[0083] In one embodiment, the rear housing 341 and the cover 342 are detachably connected to facilitate maintenance of the control device and related circuits. For example, the cover 342 and the rear housing 341 have matching cards and structures so that the cover 342 is clamped on the rear housing 341. For another example, the cover 342 and the rear housing 341 are connected by screws. In other embodiments, the cover 342 can also be set on the rear housing 341 by, for example, bonding.

[0084] In one embodiment, see Figure 4 Combined with Figure 5The cover 342 is formed with a heat dissipation port 3420. When the cover 342 is covered on the rear housing 341, the heat dissipation port 3420 is located at the rear side of the control device 33. The heat dissipation port 3420 is used to dissipate the heat generated by the control device 33 to the outside, so as to further reduce the influence of the heat generated by the control device 33 on the first preset position relationship. Figure 4 In the embodiment shown, a grille structure is formed at the heat dissipation opening 3420. This can improve the heat dissipation efficiency and protect the components inside the housing assembly 34 (for example, the control device 33, the first measuring element 31, and the second measuring element 32).

[0085] In one embodiment, in order to accelerate the conduction of heat generated by the control device to the rear, a heat-conducting layer is further disposed on the front side of the cover body, and the heat-conducting layer is used to conduct the heat generated by the control device to the cover body. The heat-conducting layer is, for example, a layer structure formed by a heat-conducting material such as a heat-conducting glue or a heat-conducting silicone grease. In other embodiments, the heat-conducting layer can also be disposed on the rear side of the control device.

[0086] To summarize, in order to overcome the technical problem in the related art that the heat generated by the control device will affect the relative position relationship between the measuring components, the measuring device and measuring equipment provided in the present application can block the heat generated by the control device from being transmitted to the front shell used to configure the first and second measuring elements by configuring at least the area surrounding the control device in the rear shell that accommodates the control device as insulating material, so as to avoid the heat generated by the control device from affecting the relative position relationship between the measuring components, thereby ensuring the measurement accuracy.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
