Description

Technical Field

[0001] This utility model relates to the field of radar detection technology, and in particular to a handheld radar device. Background Technology

[0002] With the widespread application of digital topographic maps, people have learned from the advantages of two-dimensional digital topographic map models and overcome the shortcomings of two-dimensional digital topographic maps in spatial representation and application, proposing many methods and tools for surveying and expressing three-dimensional spatial information.

[0003] Currently, mainstream equipment on the market is segmented based on target groups and functional positioning. Low-end equipment can meet the needs of users with low accuracy requirements, while high-end equipment offers more surveying methods and higher accuracy, making it more professional, but only suitable for users with high price tolerance. Therefore, there are currently no products on the market that can simultaneously meet the needs of both types of users. For example, existing mainstream handheld products are relatively low-end and are limited in terms of detection methods and accuracy. If such handheld devices were scalable and could be connected to high-precision detection modules, they could fill the market gap and meet the needs of high-end users. However, considering the small size and compact structure of handheld devices, it is difficult to make them expandable, and few manufacturers have developed related products. Utility Model Content

[0004] The main objective of this invention is to provide a handheld radar device with expandability.

[0005] To achieve the above objectives, this utility model provides a handheld radar device, including a main unit. The main unit includes a housing and a first detection module disposed on the housing. The key feature is that the housing is provided with an extension portion for connecting external components. The extension portion has a first wall and a second wall facing each other in a first direction, and a third wall intersecting the first wall and the second wall. The first wall and the second wall have groove portions extending in a second direction. The groove portions have two partition side walls and an opening portion communicating with the third wall. The extension portion also includes a slot portion disposed on the first wall and / or the second wall. The third wall is provided with a data interface. The second direction is orthogonal to the first direction and parallel to the engagement direction of the data interface.

[0006] The external component includes a body and a locking member movably disposed on the body. The body has a slider portion that engages with two recessed portions respectively. The locking member can move in a first direction. The locking member has an outward protrusion that engages with a slot portion on the side near the extension portion. The body also includes a baffle portion that can shield the third wall in a second direction.

[0007] As can be seen from the above scheme, the external component and the extension part can be engaged in the second direction through the cooperation of the slider part and the groove part. When engaged with the extension part, the external component can be locked to the extension part by a locking member movably mounted on the main body. Specifically, this is achieved by allowing the protruding part to enter the slot part, thereby restricting relative movement and separation between the external component and the extension part in the second direction. The restriction on both sides of the slider part by the partition sidewall can suppress the external component from wobbling in the corresponding direction during engagement, further ensuring the connection stability between the external component and the extension part. In the above-mentioned engagement state, the baffle part can shield the third wall with the data interface in the second direction, thereby protecting the data interface. When the external component is a functional extension component, the data connector can be mounted on the baffle part, so that the data connector and the data interface can be simultaneously connected during the engagement process between the external component and the extension part in the second direction.

[0008] A further embodiment is that the external component has a first accommodating section that extends through the main body in a first direction, and the locking member includes a rod disposed in the first accommodating section. The middle part of the rod is hinged to the main body and can rotate along a plane defined by the first direction and the second direction. The first end of the rod is connected to the main body through a force-applying member that can elastically deform along the first direction, and the protrusion is provided on the side of the second end of the rod near the extension.

[0009] As can be seen from the above scheme, the rod body can be used as a specific implementation of the locking component. The first end of the rod body, which is rotatably set on the main body, can serve as the operating end for manual unlocking, and the second end can serve as the functional end for locking the external component and the main unit. The force-applying component can use the force generated by its own elastic deformation to keep the protrusion in the slot, thereby maintaining the locking state between the external component and the main unit.

[0010] A further embodiment includes an extension portion comprising an outwardly protruding body disposed on a third-direction side of the housing, a first wall and a second wall being first-direction end walls of the outwardly protruding body, a third wall being second-direction end walls of the outwardly protruding body, a groove portion located on the first wall and the second wall on the side closer to the housing, the extension portion also including a guide strip portion formed on the first wall and the second wall on the side away from the housing, a slot portion recessed on the guide strip portion, a partition side wall comprising a third-direction end wall of the housing, an external component including a guide groove portion cooperating with the guide strip portion, the external component shielding the third-direction side of the outwardly protruding body, the third direction being orthogonal to the first direction and the second direction.

[0011] As can be seen from the above scheme, by setting the extension part based on the third-party convex side protruding from the housing, the external component connected to it is also located on the outside of the main unit. This avoids interference between the external component and the main unit during installation and also helps to improve the design freedom in terms of the shape and size of the external component. In addition, besides the cooperation between the slider part and the groove part, the external component and the extension part can also cooperate through the guide bar part and the guide groove part, which further improves the connection stability. The external component shielding the third-party convex side can better protect the extension part from damage caused by collision.

[0012] A further embodiment includes an abutment movably disposed on the main body, the abutment being movable in a third direction and abutting against the third-direction side of the external protrusion.

[0013] As can be seen from the above scheme, the introduction of the connecting component can further improve the connection stability between the external component and the host, and prevent the external component from shaking or swinging relative to the host in a third direction, thereby helping to ensure the detection accuracy of the handheld radar device in the multi-measurement mode.

[0014] A further embodiment is that the main body has a second receiving section recessed on the side near the third direction of the outer protrusion. The second receiving section has a rotating shaft and an arc-shaped inclined guide groove on the third direction side. The inclined guide groove includes a flat bottom section and an inclined bottom section. The abutment can also rotate along the plane defined by the first direction and the second direction. The abutment includes a pressure plate part and a lever part. The pressure plate part has a shaft groove that cooperates with the rotating shaft and a protrusion that cooperates with the inclined guide groove. The lever part passes through the second receiving section and the second direction side of the main body.

[0015] As can be seen from the above scheme, the pressure plate can be rotated by moving the lever, and the protrusion can slide along the flat bottom section of the inclined guide groove to the inclined bottom section and finally move to abut against the third side wall of the second accommodating area. The pressure plate can then move towards the protrusion in the third direction and abut against it, thereby preventing the external component from shaking or swaying relative to the main unit.

[0016] A further option is that the external component is a main expansion component with a second detection module, and the main expansion component has a first data connector that matches the data interface.

[0017] As can be seen from the above scheme, the main expansion component has detection capabilities and can communicate with the host via the first data connector. It can supplement or enhance the host's built-in surveying and mapping methods, thereby achieving multi-measurement integration. The main expansion component, as an optional add-on for users, does not significantly increase the overall size and weight of the device when installed on the host, and its cost is lower than purchasing a host with equivalent surveying and mapping performance separately.

[0018] A further proposed solution is that the first and second detection modules include a radar module, and / or a three-dimensional scanning module, and / or a multispectral sensor module, and / or an infrared imaging module.

[0019] As can be seen from the above scheme, the main expansion component serves as a supplement or enhancement to the host detection method. The two modules can use the same type of detection modules with different detection accuracies, or they can use different types of detection modules. Both configuration modes help to improve the overall detection efficiency and detection accuracy of the equipment.

[0020] A further design is that the first wall and the second wall are two opposing side walls of the housing in the first direction, and both the first wall and the second wall are provided with slots. The third wall is the end wall of the housing in the second direction. The external component is a secondary expansion component with a third detection module. The secondary expansion component has a second data connector that matches the data interface. The third detection module includes an RTK high-precision positioning module.

[0021] As can be seen from the above scheme, the introduction of a secondary expansion component can also enhance the performance of the main unit in conjunction with the first detection module. The expansion component, based on the housing, utilizes the space on the second side of the housing for functional expansion. The secondary expansion component, locked to its corresponding slot by two locking members, ensures the stability of the connection between the secondary expansion component and the main unit. The RTK high-precision positioning module is relatively small, and its placement on radar equipment has no special requirements, making it suitable for use as a third detection module.

[0022] A further option is that the handheld radar device also includes an external display extension that communicates with the main unit. The external display extension has a display module, and both the main unit and the external display extension have built-in wireless communication modules. The external display extension is detachably mounted on the housing.

[0023] As can be seen from the above solution, the external display extension can communicate with the host and provide real-time visual display of the surveying results, which facilitates users to perform simultaneous detection and monitoring operations, thereby helping to improve surveying efficiency.

[0024] A further solution is to include a magnetic module on the external display extension and the main unit in the handheld radar device.

[0025] As can be seen from the above solutions, existing smartphones all have high-definition display modules and wireless communication modules, which can serve as external display extensions for handheld radar devices. Furthermore, smartphones with wireless charging capabilities all have built-in magnetic components. Therefore, setting up a magnetic module inside the host device is a relatively easy connection solution between it and the smartphone.

[0026] The handheld radar device involved in this utility model can connect to external components with detection functions by introducing an extension section on the main unit, thereby supplementing or enhancing the mapping means built into the main unit. The introduction of the extension section can ensure the convenience of disassembly and assembly and the stability of connection between the main unit and the external components.

Detailed Implementation

[0046] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0048] Given that the current market only offers low-end handheld devices for 3D spatial mapping, handheld devices with scalability and the ability to connect to high-precision detection modules can fill the market gap and meet the needs of high-end users. However, considering the small size and compact structure of handheld devices, it is difficult to make them expandable, and few manufacturers have developed related products.

[0049] See Figure 1-5 and Figure 7 The expandable handheld radar device provided by this utility model includes a host 100, the host 100 includes a housing 110 and a first detection module 120 disposed on the housing 110, and the housing 110 has an extension portion 130 for connecting an external component 200.

[0050] A coordinate system (XYZ) is established with reference to host 100. The Z-axis is parallel to the height of host 100, and is defined here as parallel to the plumb line direction; specifically, the +Z-axis is defined as the opposite direction of the plumb line direction. The X and Y axes are orthogonal to the Z-axis, and can be two horizontally extending orthogonal directions. Here, the X-axis is defined as parallel to the length of host 100, and the Y-axis is defined as parallel to the width of host 100. Furthermore, the Y-axis is defined as the first direction, and the Z-axis as the second direction.

[0051] The extension portion 130 has a first wall 131 and a second wall 132 facing each other in the Y-axis direction (i.e., the first direction) and a third wall 133 intersecting the first wall 131 and the second wall 132. The first wall 131 and the second wall 132 have a groove portion 134 extending in the Z-axis direction (i.e., the second direction). The groove portion 134 has two partition sidewalls 134a and an opening portion 134b that communicates with the third wall 133. The extension portion 130 also includes a slot portion 135 provided on the first wall 131 and / or the second wall 132. The third wall 133 is provided with a data interface 136. The engagement direction of the data interface 136 is parallel to the Z-axis direction.

[0052] The external component 200 includes a body portion 210 and a locking member 220 movably disposed on the body portion 210. The body portion 210 has a slider portion 211 that respectively engages with two recessed portions 134. The locking member 220 can move along the Y-axis direction. The locking member 220 has an outward protrusion 221 that engages with the slot portion 135 on the side near the extension portion 130. The body portion 210 also includes a baffle portion 212 that can shield the third wall 133 in the Z-axis direction.

[0053] The external component 200 and the extension 130 can be engaged in the Z-axis direction through the cooperation of the slider portion 211 and the groove portion 134. When engaged with the extension 130, the external component 200 can be locked to the extension 130 by a locking member 220 movably mounted on the body portion 210. Specifically, this is achieved by having the protrusion 221 enter the slot portion 135, thereby restricting relative movement and separation between the external component 200 and the extension 130 in the Z-axis direction. The restriction on both sides of the slider portion 211 by the partition sidewall 134a suppresses wobbling of the external component 200 in the X-axis direction during engagement, further ensuring the connection stability between the external component 200 and the extension 130. In the engaged state, the baffle portion 212 can shield the third wall 133, where the data interface 136 is located, in the Z-axis direction, thereby protecting the data interface 136. When the external component 200 is a functional expansion component, the data connector can be set on the baffle portion 212, so that the data connector and the data interface 136 can be docked synchronously during the engagement process between the external component 200 and the expansion portion 130 in the Z-axis direction.

[0054] The external component 200 has a first accommodating section 230 that extends through the main body 210 in the Y-axis direction. The locking member 220 includes a rod 222 disposed in the first accommodating section 230. The middle part of the rod 222 is hinged to the main body 210 and can rotate along the YZ plane. The first end of the rod 222 is connected to the main body 210 through a force-applying member 223 that can elastically deform along the Y-axis direction. The protrusion 221 is provided on the side of the second end of the rod 222 near the extension 130.

[0055] The rod 222 can be a relatively simple implementation of the locking member 220. The first end of the rod 222, which is rotatably set on the main body 210, can serve as the operating end for manual unlocking. The second end of the rod 222 can serve as the functional end for locking the external component 200 and the main unit 100. The force-applying member 223 can hold the protrusion 221 in the slot 135 by the force generated by its own elastic deformation, thereby maintaining the locking state between the external component 200 and the main unit 100. In this embodiment, a compression spring is used as the force-applying member 223.

[0056] Considering the product positioning, the first detection module 120 integrated into the host 100 has relatively low requirements for detection accuracy. In the following embodiments, the first detection module 120 includes a first radar module 121 configured on the +Z axis side of the housing 110, and first optical lenses 122 configured on opposite sides of the housing 110 in the Y axis direction. The two first optical lenses 122 can have some differences in their functional positioning. For example, one can focus on capturing visual contour and texture information, while the other focuses on capturing environmental color information. The positions of the two first optical lenses 122 can be interchanged. The above is only one configuration example of the first detection module 120. Based on different host 100 design schemes and positioning, the first detection module 120 can also have other configuration options.

[0057] The housing 110 is connected to a handle 400 on the -Z side for easy gripping and operation. The circuit system inside the main unit 100 also includes a main control module (not shown in the figure) electrically connected to the first detection module 120 and the data interface 136. Additionally, the main unit 100 contains a battery (not shown in the figure) to power the circuit system. Both the main control module and the battery can refer to conventional configurations in the art and are not limited here. The battery can be configured inside the handle 400, which has a charging interface (not shown in the figure), allowing direct charging of the battery via the handle 400. The main unit 100 and the handle 400 are electrically connected via a power supply interface 140. A quick-release structure can also be introduced between the handle 400 and the main unit 100 for a fixed connection. When the power of a single handle 400 is depleted, it is easy to replace it with another handle 400 to recharge the main unit 100. Furthermore, the handheld radar device proposed in this invention can be applied to the field of Simultaneous Localization and Mapping (SLAM).

[0058] See Figure 15 In some embodiments, the end of the handle 400 may also be connected to a base 410 to place the main unit 100 with the external component 200 connected to it stably on other objects, or to further achieve a fixed connection with other objects by means of the base 410.

[0059] Example 1 See Figure 1-5 The handheld radar device proposed in this embodiment conforms to the general description above in terms of its basic structure and the connection form of the external component 200. In this embodiment, the protective cover 200a is used as the external component 200. The extension 130 is based on the protrusion 130a provided on the +X axis direction side of the housing 110. The first wall and the second wall 132 are the Y axis direction end walls of the protrusion 130a, and the third wall 133 is the +Z axis direction end wall of the protrusion 130a. The groove 134 is located on the side of the first wall 131 and the second wall 132 close to the housing 110. The extension 130 also includes a guide strip 137 formed on the side of the first wall 131 and the second wall 132 away from the housing 110. The slot 135 is recessed on the guide strip 137. The partition side wall 134a includes the +X axis direction end wall of the housing 110. The protective cover 200a also includes a guide groove 213 that cooperates with the guide strip 137. The external component 200 covers the +X axis direction side of the protrusion 130a.

[0060] The extension portion 130 is provided based on the protrusion 130a protruding from the +X axis direction side of the housing 110. The external component 200 connected to it is also located on the outside of the main unit 100, which avoids interference between the external component 200 and the main unit 100 during installation and also helps to increase the design freedom in terms of the shape and size of the external component 200. Furthermore, in addition to the cooperation between the slider portion 211 and the groove portion 134, the external component 200 and the extension portion 130 can also cooperate through the guide strip portion 137 and the guide groove portion 213, further improving the connection stability. The external component 200 shielding the +X axis direction side of the protrusion 130a better protects the extension portion 130 from damage caused by collisions.

[0061] When using the host 100 alone for surveying, there is no need to remove the protective cover 200a. The protective cover 200a is only required to be removed when an external component 200 with detection function is connected to expand the functionality.

[0062] Example 2 See Figure 6-9 The handheld radar device proposed in this embodiment conforms to the general description above in terms of its basic structure and the way it connects with the external component 200. In this embodiment, the main expansion component 200b with a second detection module 240 is used as the external component 200. The main expansion component 200b has a first data connector 214 that matches the data interface 136. The main expansion component 200b mates with the expansion portion 130 based on the external protrusion 130a in Embodiment 1, and the mating method is the same as the mating method between the protective cover 200a and the external protrusion 130a. The relevant structural features follow the reference numerals in the drawings of Embodiment 1.

[0063] Based on this, the main extension member 200b also includes an abutment member 250 movably disposed on the main body 210. The abutment member 250 can move along the X-axis direction and abut against the +X-axis direction side of the outer protrusion 130a. The main body 210 has a second accommodating section 260 recessed on the side near the +X-axis direction side of the outer protrusion 130a. The second accommodating section 260 has a rotating shaft 261 and an arc-shaped inclined guide groove 262 on the -X-axis direction side. The inclined guide groove 262 includes a flat bottom section 262a and an inclined bottom section 262b. The abutment member 250 can also rotate along the YZ plane. The abutment member 250 includes a pressure plate section 251 and a lever section 252. The pressure plate section 251 has a shaft groove 2511 that mates with the rotating shaft 261 and a protrusion 2512 that mates with the inclined guide groove 262. The lever section 252 passes through the second accommodating section 260 and the -Z-axis direction side of the main body 210.

[0064] The introduction of the abutment member 250 can further improve the connection stability between the external component 200 and the host 100, and prevent the main extension member 200b from shaking or swaying relative to the host 100 in the X-axis direction, thereby helping to ensure the detection accuracy of the handheld radar device in the multi-measurement mode. By tossing the lever 252, the pressure plate 251 can be rotated, and the protrusion 2512 can slide along the flat bottom section 262a of the inclined guide groove 262 to the inclined bottom section 262b and finally move to abut against the side wall surface in the X-axis direction of the second accommodating interval 260. The pressure plate 251 can correspondingly move close to the outer protrusion 130a in the X-axis direction and abut against the outer protrusion 130a, thereby preventing the main extension member 200b from shaking or swaying relative to the host 100.

[0065] The main expansion component 200b has a detection function and can be connected to the main control module of the host 100 (not shown in the figure) through the first data connector 214 to realize communication and interaction with the host 100 and be powered by the battery of the host 100. Therefore, it can be used as a supplement or enhancement to the surveying and mapping means built into the host 100 and realize multi-measurement integration.

[0066] The main expansion component 200b, which can be purchased later by the user, does not significantly increase the overall size and weight of the device when added to the main unit 100. Compared to purchasing a separate main unit with the same surveying performance as the main expansion component 200b, it is less expensive. Furthermore, since the main expansion component 200b and the main unit 100 move along the same trajectory and can synchronize data in real time, it is more conducive to achieving multi-measurement integration. Considering that the main expansion component 200b and the main unit 100 are connected via the expansion section 130 and have good connection stability, the main expansion component 200b has relatively few limitations in terms of weight and size.

[0067] The configuration of the second detection module 240 is quite diverse, therefore this embodiment has multiple implementation forms, see [link to relevant documentation]. Figure 6-9In this embodiment, a second radar module 241 is used as the second detection module 240 to enhance the detection capabilities of the host 100. Preferably, the second radar module 241 has a higher detection accuracy than the first radar module 121. See also... Figure 10 , 11 In this embodiment, an optical scanner 242 is used as the second detection module 240. The optical scanner 242 can be a grating scanner or a spot scanner. The optical scanner 242 is used to enhance the optical detection performance of the host 100 and facilitate the modeling of small objects. Both grating scanners and spot scanners are not available in existing handheld radar devices, and both belong to the category of three-dimensional scanning modules.

[0068] See Figure 12 , 13 In this embodiment, a second optical lens 243 is used as the second detection module 240 to enhance the optical detection means of the host 100. Preferably, the second optical lens 243 has a higher resolution than the first optical lens 122. Furthermore, a filter 243a can be installed on the second optical lens 243 to improve its performance; here, the filter 243a can be understood as an accessory of the second optical lens 243.

[0069] As can be seen from the above, the second detection module 240 in this embodiment can incorporate a detection module of the same type as the first detection module 120, or it can incorporate a detection module different from the first detection module 120. Both configuration modes help improve the overall detection efficiency and accuracy of the device. The above embodiments are only some configuration examples of the second detection module 240. Furthermore, both the first detection module 120 and the second detection module 240 can also be selected from other types of detection modules with relatively mature technology, such as multispectral sensor modules, infrared imaging modules, etc.

[0070] See Figure 3 , 6 This embodiment also includes an external display extension 300 that is communicatively connected to the host 100. The external display extension 300 includes a display module 310. Both the host 100 and the external display extension 300 have built-in wireless communication modules (not shown in the figure). The external display extension 300 is detachably mounted on the housing 110. In this embodiment, the external display extension 300 is magnetically connected to the host 100, and the host 100 has a magnetic module 150 disposed on the -X-axis side of the housing 110. This embodiment uses a smartphone with wireless charging capability as the external display extension 300, which has a magnetic component (not shown in the figure) that can act as a magnetic module.

[0071] The external display extension 300 can communicate with the host 100 and provide real-time visual display of the surveying results, facilitating simultaneous detection and monitoring operations by the user and thus improving surveying efficiency. Existing smartphones all possess high-resolution display modules 310 and wireless communication modules, which can serve as external display extensions 300 for handheld radar devices. Users can simply attach their smartphones to the host 100 and complete the connection and pairing process to use them as external display extensions 300, eliminating the need to purchase dedicated external display extensions and thus saving on hardware costs.

[0072] Considering that smartphones with wireless charging capabilities all have built-in magnetic connectors, setting up a magnetic module 150 inside the main unit 100 is a relatively easy connection solution between it and the smartphone. The connection method between the main unit 100 and the external display expansion component 300 is not limited to magnetic attraction. In other embodiments, the housing 110 and the external display expansion component 300 can also be detachably connected by means of snap-fit, fitting, or adhesive.

[0073] In other implementations, the external display extension 300 can also be a dedicated accessory developed for the host 100. This type of external display extension 300 can have a built-in power supply or draw power from the host 100 via a relevant physical interface. The external display extension 300 and the host 100 can communicate wirelessly or via a physical data interface. This customized solution for the external display extension 300 ensures a high degree of compatibility with the host 100.

[0074] Example 3 See Figure 14-16 The handheld radar device proposed in this embodiment conforms to the general description above in terms of its basic structure and the way it connects with the external component 200. In this embodiment, the external component 200 is a secondary expansion member 200c equipped with a third detection module 270, and the secondary expansion member 200c has a second data connector 215. The third detection module 270 mounted on the secondary expansion member 200c in this embodiment has an RTK (Real-Time Kinematic) high-precision positioning module, which can provide real-time location information to the host 100. The RTK high-precision positioning module is small in size and has no special requirements for its placement on the radar device, making it suitable for use as the third detection module 270.

[0075] In this embodiment, an extension portion 130 is provided based on the housing 110. The first wall 131 and the second wall 132 are two side walls of the housing 110 facing each other in the Y-axis direction. The first wall 131 and the second wall 132 are both provided with a slot portion 135. The third wall 133 is the end wall of the housing 110 in the +Z-axis direction.

[0076] The introduction of the secondary expansion component 200c can also work in conjunction with the first detection module 120 to improve the performance of the host 100. The expansion part 130 based on the housing 110 can utilize the space arranged on the +Z axis side of the housing 110 for functional expansion. The secondary expansion component 200c can be locked with the corresponding slot part 135 by two locking parts 220 to ensure the connection stability between the secondary expansion component 200c and the host 100.

[0077] See Figure 3 In order to protect the data interface 136 when the secondary expansion piece 200c is not connected, a soft rubber cover 138 can be provided on the housing 110 to cover the data interface 136. The end of the soft rubber cover 138 is fixedly connected to the housing 110 to prevent loss.
