They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] The following is for reference. Figures 1-7 The specific structure of the probe module 100 disclosed in this utility model is described.

[0034] This utility model discloses a probe module 100, with reference to... Figures 1-3 As shown, the probe module 100 includes a main board 110, a protective cover 130, and a fixing structure 140. The main board 110 is provided with multiple probe units 120. The protective cover 130 has an open side. The protective cover 130 and the main board 110 define a protective cavity 101. The multiple probe units 120 are located in the protective cavity 101. The fixing structure 140 is provided on the side of the main board 110 away from the probe units 120 and is connected to the open side. The fixing structure 140 is used to fix the probe module 100 to the cooling base 200. Understandably, during the actual assembly process, after fixing multiple probe units 120 onto the motherboard 110, the fixing structure 140 is installed on the side of the motherboard 110 away from the probe units 120. Then, the protective cover 130 is placed over the probe units 120 and fixedly connected to the fixing structure 140. At this point, the entire probe module 100 is assembled into a modular structure. When installing the probe module 100 onto the cooling base 200, it is only necessary to install the modular structure onto the cooling base 200, so that the fixing structure 140 and the cooling base 200 are connected. The probe module 100 of this invention can be completed with a fixed connection. Compared with the existing technology, which usually involves first installing the probe and its circuit board onto the cooling base and then covering the probe and its circuit board with a protective cover, the probe module 100 of this invention adds a fixing structure 140 for connecting the main board 110 and the protective cover 130. This allows the probe module 100 to be assembled first and then installed onto the cooling base 200. This makes the assembly operation of the probe module 100 and the cooling base 200 very simple and less likely to cause deformation of the protective cover 130. It also provides better protection and shielding for the probe unit 120.

[0035] refer to Figure 3As shown, the motherboard 110 has multiple connector terminals 1111, which are spaced apart along the length of the motherboard 110. The probe unit 120 is detachably connected to the motherboard 110 via the connector terminals 1111. It is understood that connecting the probe unit 120 to the motherboard 110 via the connector terminals 1111 facilitates the installation and removal of the probe unit 120, thereby further simplifying the assembly of the probe module 100. Furthermore, by using the connector terminals 1111, after multiple probe units 120 are inserted into the motherboard 110, there is almost no gap between adjacent probe units 120, and the distance between the probe unit 120 and the motherboard 110 is also small, which helps to improve the structural compactness of the probe module 100, thus contributing to the miniaturization design of animal imaging equipment.

[0036] Optionally, there are multiple sets of connector terminals 1111, with each probe unit 120 corresponding to one set of connector terminals 1111, and each set of connector terminals 1111 includes at least two connector terminals 1111. It is understood that each probe unit 120 connects to the motherboard 110 through at least two connector terminals 1111, which helps improve the reliability of the connection between the probe unit 120 and the motherboard 110, thereby ensuring communication between them. In this embodiment, each set of connector terminals 1111 includes two connector terminals 1111. Of course, in other embodiments of this invention, each set of connector terminals 1111 may also include three, four, or even more connector terminals 1111, and the number of connector terminals 1111 can be determined according to the size of the probe unit 120.

[0037] refer to Figure 3 As shown, there are multiple fixing structural members 140, which are arranged at intervals along the outer contour of the opening side. The fixed connection between the main board 110 and the protective cover 130 by multiple fixing structural members 140 can improve the connection stability and sealing of the main board 110 and the protective cover 130. On the one hand, it ensures the structural reliability of the probe module 100, and on the other hand, it provides better protection and shielding for the probe unit 120.

[0038] Optionally, at least one fixing structure 140 is located at a corner of the protective cover 130. The protective cover 130 is usually formed into a cuboid cover by bending sheet metal, and its corners are relatively easy to deform. In this embodiment, placing the fixing structure 140 at the corner of the protective cover 130 can improve the strength of the protective cover 130 and prevent the protective cover 130 from deforming during the installation process.

[0039] refer to Figures 3-5As shown, each fixing structure 140 includes a first fixing part 141 and a second fixing part 142 connected together. The first fixing part 141 is connected to the motherboard 110 and the cooling base 200 through a first connector (not shown in the figure), and the second fixing part 142 is connected to the protective cover 130 through a second connector (not shown in the figure). Understandably, in the actual assembly process, the first fixing part 141 is pre-fixed to the motherboard 110, then the protective cover 130 is placed over the probe unit 120 and the motherboard 110. Next, a second connector passes through the protective cover 130 and connects to the second fixing part 142, fixing the protective cover 130 to the motherboard 110. Finally, the assembled probe module 100 is placed on the cooling base 200, and the first fixing part 141 is connected to the motherboard 110 and the cooling base 200 via the first connector to complete the assembly. The connection method using the first and second connectors ensures the connection stability between the fixing structure 140 and the motherboard 110, the cooling base 200, and the protective cover 130, which is beneficial for ensuring the installation stability of the probe module 100. In this embodiment, the first and second connectors are connecting screws. Of course, in other embodiments of this utility model, the first and second connectors can also be fixing pins or other structures.

[0040] It should be further explained that there are several ways to pre-fix the first fixing part 141 to the motherboard 110. For example, in some embodiments, a fixing screw can be used to fix the first fixing part 141 to the motherboard 110. When installing the probe module 100, the fixing screw can be removed to install the first connector. In some embodiments, double-sided adhesive can be used to temporarily stick the first fixing part 141 to the motherboard 110. In some embodiments, a plug-in post can be provided on the first fixing part 141 and a plug-in hole can be provided on the motherboard 110. The first fixing part 141 can be fixed to the motherboard 110 by plugging in.

[0041] refer to Figures 4-5 and Figure 7As shown, the second fixing part 142 has one or two abutment surfaces 1421, which abut against the inner sidewall of the opening side. Each abutment surface 1421 is provided with a second connector. It can be understood that by providing abutment surfaces 1421 on the inner sidewall of the opening side on the second fixing part 142, the second fixing part 142 can provide good support for the protective cover 130. While ensuring the connection between the fixing structure 140 and the protective cover 130, it is beneficial to improve the deformation resistance of the protective cover 130, thereby improving the protection and shielding effect on the probe module 100. It should be noted that, and further explanation is needed, that in the actual design, all the fixing structural members 140 can be of one type, that is, the second fixing part 142 of the fixing structural member 140 is provided with two abutment surfaces 1421 (the structure of this embodiment). The fixing structural member 140 installed at the corner of the opening side of the protective cover 130 and the fixing structural member 140 installed at the middle position of the opening side of the protective cover 130 are completely identical in structure. Of course, two types of fixing structural members 140 can also be designed, one with one abutment surface 1421 and used for installation at the middle position of the opening side of the protective cover 130, and the other with two abutment surfaces 1421 and used for installation at the corner position of the opening side of the protective cover 130.

[0042] Optionally, the protective cover 130 can be made of metal. Using metal for the protective cover 130 can provide good protection and shielding. The specific type of metal chosen for the protective cover 130 can be selected based on a comprehensive consideration of processing requirements and equipment manufacturing costs.

[0043] Optionally, the fixing structure 140 is an injection-molded part. Using an injection-molded part for the fixing structure 140 facilitates manufacturing and reduces costs; it also makes the fixing structure 140 lighter, thus contributing to the lightweight manufacturing of the probe module 100. Of course, in other embodiments of this invention, the fixing structure 140 can also be made of other materials according to actual needs.

[0044] refer to Figures 4-5 As shown, the motherboard 110 has a dual-board structure, including a first board 111 and a second board 112. The first board 111 is used to mount the probe unit 120. The first connector passes through the cooling base 200 and the first fixing part 141 of the fixing structure 140 in sequence and connects to the second board 112. It can be understood that the motherboard 110 has a dual-board structure, and the fixing structure 140 is mounted on the second board 112. The size of the fixing structure 140 is not limited by the distance between the first board 111 and the second board 112, and can be designed according to actual needs, providing good flexibility.

[0045] In an alternative embodiment of this utility model, the motherboard 110 has a dual-board structure, including a first board 111 and a second board 112. The first board 111 is used to mount the probe unit 120. A first connector passes sequentially through the cooling base 200, the first board 111, and the first fixing part 141 of the fixing structure 140 to connect with the second board 112. Compared to the embodiment in which the fixing structure 140 is mounted on the second board 112, in the alternative embodiment, the fixing structure 140 is sandwiched between the first board 111 and the second board 112. In actual installation, it is only necessary to install the fixing structure 140 into the gap between the first board 111 and the second board 112, without the need for a special pre-fixing structure, which facilitates assembly.

[0046] refer to Figure 6 As shown, the protective cover 130 includes an integrally formed top plate 131, two first side plates 132 and two second side plates 133. The two first side plates 132 are connected to both sides of the top plate 131 along its width direction, and the two second side plates 133 are connected to both sides of the top plate 131 along its length direction. The first side plates 132 are provided with first extensions 1321 that abut against the second side plates 133 at both ends along the length direction of the top plate 131. Understandably, in the actual manufacturing process, a single sheet metal can be bent to form two first side plates 132 and two second side plates 133 connected to the top plate 131 to initially form a cuboid-shaped cover. Then, at the corner of the cuboid-shaped cover, the first extension 1321 of the first side plate 132 extending beyond the second side plate 133 is bent inward and abutted against the second side plate 133 to complete the manufacturing of the protective cover 130. This bending and forming method can simplify the manufacturing process of the protective cover 130, reduce the manufacturing cost of the protective cover 130, and the first extension 1321 can improve the sealing of the entire protective cover 130, thereby improving the protection and shielding effect of the probe unit 120.

[0047] In addition, to further improve the sealing performance of the protective cover 130, the joints of the first side plate 132 and the second side plate 133 can be connected together by welding.

[0048] In an alternative embodiment of this invention, the second side plate 133 is provided with second extensions at both ends along the width direction of the top plate 131, which abut against the first side plate 132. Providing second extensions on the second side plate 133 can also improve the sealing performance of the entire protective cover 130, thereby enhancing the protection and shielding effect on the probe unit 120.

[0049] This utility model also discloses an animal imaging device, including the aforementioned probe module 100, multiple cooling bases 200, and an animal chamber. The animal chamber is used to accommodate the animal to be imaged. The multiple cooling bases 200 are arranged around the animal chamber, and at least one probe module 100 is disposed on each cooling base 200. Because of the aforementioned probe module 100, in the actual assembly process, the probe module 100 can be assembled first and then installed onto the cooling base 200. This makes the assembly operation of the probe module 100 and the cooling base 200 very simple and less likely to cause deformation of the protective cover 130, thus providing good protection and shielding for the probe unit 120, thereby improving the imaging quality and accuracy of the animal imaging device.
